Description

The invention relates to a route section in the glued laminated timber, in particular for a multipurpose road, serving in particular as a driving route under the support surface for lines deck surface, spaced from the top surface, in particular serving as a further route and / or support surface for lines end surface and a over the entire Length of the route section extending cavity.

From the EP 1 805 366 B1 is a multipurpose road made of laminated wood. This has a central cavity which has a top surface which serves as a travel path. In addition to this, a further route or a support surface for lines can be provided in the interior.

A disadvantage of the prior art has been found that with increasing support load made of glued timber construction is no longer able to remove such forces acting on the multipurpose road in the underlying supports. The load-bearing capacity of the glulam timber forming the multipurpose road is thus the limiting factor for the navigability or loading capacity of the multipurpose roadway known from the prior art.

A further disadvantage is that the available in the known multipurpose road cavity is limited and only a certain number of lines for resources or the like can be included. In addition, there is no possibility to carry out a spatially separated implementation of compatible substances in the cavity. This can only take place if complicated separation measures are carried out on the individual lines, for example gas or electricity or oil lines, which are associated with considerable costs.

Object of the present invention is therefore to provide a route section for a multipurpose road, which is able to derive high contact forces permanently to the substructure of the multipurpose road and also to provide separate rooms for a variety of transport cables or lines available.

This object is achieved by the path section described above, which is provided for a multipurpose road.

According to the invention, it is provided that the route section has a two-layered or multi-layered structure, wherein this two-layered or multi-layered structure is achieved by drawing in a plurality of side walls between the top surface and the end surface. The additional side walls improve the discharge of the support loads. In addition, the sidewalls stabilize the entire construction of the track section as well as the multipurpose road formed therefrom. In addition to the improved dissipation of support loads and the overall structure of the multipurpose road is greatly simplified. In addition, additional rooms or chambers in the route section and thus the entire multipurpose road are provided by the additional side walls, which allows the spatially separate transport of different media or raw materials.

The side walls preferably have a similar or different structure. Depending on the forces introduced or the type and direction of the introduction of force, the side walls are selected in the route section. Thus, for example, internal side walls, which are also weather-protected due to further angezusetzendem side walls, only of glued laminated timber or glued laminated timber, which has reinforcements inside, while the outer, the route section to the outside final side walls of a glulam with an additional , in particular weather-resistant or stabilizing layer are provided. Of course, there is also the possibility that the side walls of the route section have a similar structure.

It is considered advantageous if at least one side wall is formed from glulam. In this case, of course, there is the possibility and it is encompassed by the invention when the side panel consisting of glulam undergoes a modification or reinforcement, for example in the form of inserted or interposed reinforcing or stabilizing layers.

The glulam wood known from timber construction can consist of solid wood, plywood or hardboard webs. The laminated timber always has a layered structure, because the layers are usually made of the same type of wood. The advantage of glued laminated timber is that the otherwise disadvantageous properties of the wood, namely the tendency to shrink or swell, are made uniform by the combination or clever connection of the individual layers. The shrinkage tendency of glued laminated timber is thus far below that of solid wood. For the production of glued laminated timber, the individual layers are bonded by weather-resistant glues, in particular, and hardened by a pressing process. These layers may additionally have further modifications in order to further improve the equalization of the shrinkage tendency of the solid wood.

In connection with the present invention, it is considered favorable if the side wall or side walls has an at least two-layered construction. The two layers can be formed either the same or different.

An embodiment which is regarded as favorable provides that a first layer of the side wall is formed from wood or glued laminated timber, and a second layer of laminated wood or wood is applied as the second layer, or the second layer is formed as a cast-on layer of concrete. This is considered to be particularly favorable when fiber reinforced or reinforced concrete is used to form the further layer.

If the first layer is made of wood or glued laminated timber, it is provided in a further development of the line section according to the invention that the first and second layers are connected via a positive connection, in particular a dovetail connection.

By using appropriate positive connections, the shear behavior between the superimposed layers is substantially improved and the stability of the side wall or wall thus formed is further improved. The wood-concrete composite formed in this way represents an economical construction form. The advantages of the wood-concrete composite are manifold. While the concrete is in the bending pressure zone of the structure, the wood or layer formed of wood lies in the bending tension zone. Thus, the dominant strength properties of both materials can be used, in particular the compressive strength of the concrete and the tensile strength of the wood. The combination of concrete and wood significantly increases the load bearing capacity of the construction. By the Auflagerung a concrete layer on the glued laminated timber layer also the susceptibility to vibration of a pure wooden wall is improved or reduced. The combination of wood and concrete also reduces the sound insulation properties of the walls thus formed and also significantly improves fire safety. The wall construction formed is not limited to the use of glued laminated timber. There is also the possibility that here trunk wood, solid wood or wood panels are used. The use of veneer panels or board materials made of wood materials is equally possible in combination with the concrete. In addition to the addition of fibers to the concrete layer, which should improve their tensile strength, there is of course also the possibility that the wood or concrete layer connecting reinforcements, for example. Armierungseisen or bolts are used, which stand both in the wood layer and the concrete layer and thus ablating the shear forces occurring improved.

Since concrete and wood have different coefficients of expansion, there is the additional possibility and it is considered favorable when a release layer is applied between the two layers, which is able to compensate for the different dimensions without causing any cracks or other distortions in the individual layers comes.

A further embodiment of the side wall or walls considered to be favorable provides that layers of glued laminated timber are provided and at least one reinforcing layer, in particular of metal, preferably of steel, is provided between the layers. Of course, in addition to the use of metal or steel, it is also possible here to use any suitable reinforcing layers with materials. Thus, for example, it is conceivable that, instead of a metal or steel insert or reinforcing layer, a layer made of a fiber composite material is inserted between the layers of laminated wood. The reinforcing layer takes the layers formed from glulam from each other. Of course, alternatively or additionally, it is also possible to insert reinforcing layers into the glued laminated timber or to create corresponding reinforcing layers in the formation of the glued laminated timber side wall in combination with a reinforcing layer.

It is considered advantageous if the reinforcing layer has a fold at at least one end. The first layer of glued laminated timber then rests on this fold or is encompassed by it.

In the reinforcing layer projections may additionally be provided, which protrude into the layer of glued laminated timber or positively engage in this and here significantly improve the connection between the reinforcing layer and glulam location.

Another possibility for the connection between reinforcing layer and glulam layer or the layer of wood or glued laminated timber is that at least one recess or bore is provided in the reinforcing layer and in layers of wood or glulam. In the recess or bore then the reinforcing layer and the layers of wood or glulam penetrating fastener is inserted or inserted and thus leads to a permanent stable connection between reinforcing layer and wood layer or layer of wood.

In a preferred development, the connecting elements can also be used to receive connecting means which engage or are introduced into the wood or glulam layer. This results in a further improved stabilization of the connection between reinforcement layer and wood layer is created.

It is considered advantageous if the cavity is subdivided into several chambers extending in the longitudinal direction of the route section. This subdivision is achieved by installing one or more side walls. The side walls thus not only assume a support and stabilization function for the route section, but also a subdivision or breakdown of the inner cavity provided in the route section and thus the multi-purpose road formed from the route section. The chambers are available for the arrangement of supply, disposal or transport lines. In addition, there is the possibility that here transport pipes, eg. For oil, natural gas pipelines, water pipes or the like are laid in the multipurpose road. This ensures optimal use of the route. This not only serves as a transport route for goods or the like, but can also be used for the long-distance transport of raw materials or energy. By Kammerung the cavity can also be done here the transport of critical media. Thus, for example, electricity can be transported separately from gas without having to take additional safety measures, such as, for example, a separate insulation of the respective transport tubes or lines. In addition to the reinforcing layer or stabilizing layer, a shielding or insulating layer can be applied to the side wall. Here, for example, electrosmog or the like can be shielded, so that the multipurpose road is also available for use, for example. In densely populated areas available.

In order to further improve the stability of the route section, it is considered favorable if stiffening frames are arranged in the chambers. On the one hand, these stiffening frames stabilize the individual chambers or cavities of the route section and thus of the multipurpose road. On the other hand, it is considered advantageous if additional stanchions or supports for pipes and / or lines guided in the chambers are provided on the stiffening frame. By installing or using appropriate stiffening frame, a functionalization of the route section can be performed later. If, for example, additional pipes or conduits are to be inserted into the cavity or the individual chambers of the route section, then by choosing the suitable stiffening frame or brackets and / or supports arranged on the stiffening frame, they can be aligned or set up accordingly. The stiffening frame can of course also be provided directly in the production of the route section in this.

In a preferred embodiment of the route section, this has two outer side walls and two inner side walls. The outer side walls in this case have a first layer of wood or glued laminated timber, on which a second, with the first layer positively connected layer is applied. This second layer is formed as cast from concrete pad. The inner side walls of the route section consist in the preferred embodiment of glulam with at least one arranged between the layers reinforcing layer, in particular of metal or other suitable material, eg. A fiber composite material. For the individual layers of the side walls can be conveniently introduced a shielding or insulation layer. Of course, the above-described route section is not limited to the design with two outer and two inner side walls, but rather there is the possibility here to install or introduce a freely selectable number of additional walls. Also, the formation of the individual side walls is not limited to the embodiment described above, but rather it is possible to provide the described side walls in various combinations or arrangement variants.

It is considered advantageous if the relative to the cavity outer surface of the route section of concrete, in particular a fiber reinforced or reinforced concrete are formed. These concrete walls are preferably combined with a layer of wood or glulam. The advantage of the outer side walls made of concrete is that it is significantly improved by the weather resistance of the route sections and the multipurpose road formed therefrom.

The stability of the route section is further increased by support elements, for example. Struts, stiffeners or the like are provided in the cavity. A considered as favorable type of bracing or stiffening is the use of a steel or corrugated steel carrier. This may preferably be formed as T or double T-steel or corrugated steel beams. As low it is considered in this context, if in the cavity or in the interior of the chambers of the route sections guides, receptacles or arrangement points are provided for the support elements. In addition to the guide elements, in which the support elements engage positively or can be inserted or inserted, there is also the Possibility that the respectively provided support elements, eg. Struts, stiffeners or steel or corrugated steel carrier with the top surface and the end surface or a part thereof are frictionally connected, in particular screwed, verniet- or vernagelbar. The use of additional stiffeners or struts further increases the bearing loads that can be absorbed by the line and thus improves their stability and versatility, in particular as regards the transport of goods or the arrangement of pipes or conduits inside the multipurpose line formed from the route sections.

Equally encompassed by the invention is a multipurpose line formed from a plurality of line sections as previously described. As possible, considered as favorable embodiment is considered, if the side walls of the individual route sections have trapezoidal shape and the route sections are arranged alternately to each other. The obliquely extending end faces of the trapezoidal side walls lie in each case with the essential part of their surface non-positively or positively against each other. In order to improve the connection between the contact points or to achieve a seal of the multipurpose roadway formed from the route sections, in particular the contact point of the end faces is permanently elastic sealed or provided between the contact points at least one seal. This seal is able to compensate for expansions or shrinkages of the side walls or the individual line sections and thus to provide a permanently torsion-free and gap-free multi-purpose roadway.

In this context, it is considered favorable if the angle of inclination of the frontal contact surfaces of the route sections with respect to the base area is at least 5%.

Another alternative and advantageous development of the multipurpose road provides that the side walls of the individual route sections have aligned perpendicular to the longitudinal axis of the route section end faces. The end faces also lie with the essential part of their surface non-positively or positively against each other. Again, the contact points of the end faces are permanently elastic sealed or at least one seal is provided between the contact points, which compensates for the movement of the individual line sections and yet ensures the tightness of the multipurpose line. In the multipurpose road, a number of route sections and / or routes are advantageously arranged one above the other or next to each other. As a route within the meaning of the present invention, all paths or routes are to be seen, which are passable by vehicles. These include, in particular, freely passable sections but also track sections or guide rails for track-guided vehicles, such as, for example, magnetic tracks or the like.

The multi-purpose road according to the invention is characterized in that the route sections are each arranged on at least one buttress. The pillars are preferably arranged in one or more rows.

It is considered to be advantageous if the or the supporting pillars at its or its the line section bearing end (s), support (s) made of wood, in particular solid wood / has. This support interacts with the end face of the track section or a part thereof or forms the final surface itself. It is considered favorable if the grain of the wood is oriented substantially perpendicular to the longitudinal direction of the line section. This has the advantage that in the fiber direction of the wood, the shrinkage tendency is less than parallel to the fiber direction and thus no significant dimensional or shape or position changes of the wood support take place. To form the support, it is considered favorable if durable, in particular a steel stock, a steel strip, a steel strip or the like interconnected logs or wooden beams are used. In particular, the use of solid wood proves to be advantageous here, since so the favorable properties of the wood can be fully utilized and a completely made of regenerative materials support pillars is provided. It is further considered to be advantageous if the support has a shoulder and the shoulder forms a contact surface for the side walls. This embodiment simplifies the construction of the route section or the multipurpose road substantially. Thus, for example, a route section which is previously formed or an inner body of the route section is first placed on the support and afterwards the side walls are attached to this route body. The support or paragraph provided there then determines the position of the side wall and stabilizes the entire construction.

A development considered advantageous provides that a compensation gap is provided in the support. This compensating joint also extends in the direction of the fiber into the support and can compensate for movements of the line sections or dimensional changes of the materials. Furthermore, a compensation joint proves to be advantageous if, for example, individual route sections are removed from the multipurpose line in order to be replaced or repaired.

In order to ensure a positive connection of the support and the raceway section, it is considered advantageous if complementary guide elements are provided in the support and the surface facing the support of the route section. These can be formed, for example, as a conical guide cam and complementary recesses. When placing the route sections on the support or the pillars, these guide elements interlock, so that the route section slides onto the support and is positioned accordingly. Of course, in addition to or as an alternative to the shape-complementary recesses or guide elements in the support, there is also the possibility that connection structures which are complementary to one another or are provided at the contact points between the route sections are provided. These connection structures can also be designed as separate components detachably fixed to the contact points, in particular made of metal or plastic, and enable or ensure a precise and highly accurate connection between the line sections of the multipurpose line according to the invention. In order to seal the route section against each other, it is considered favorable if at least one circumferential seal, in particular at least one steel spring seal, is arranged at the front-side contact points of the route sections. This is compressed when placing or inserting the route sections and thereby seals the contact point between the route sections permanently. In addition to the use of a steel spring gasket, of course, there is also the possibility that here elastic seals, such as. Rubber profiles or the like can be used.

The invention equally includes a wall, in particular a side wall for a multipurpose road or a route section. This wall preferably has a structure made of wood, for example. Glued wood or glued laminated timber with an applied on at least one surface of the wood or glulam wood reinforcing layer. As low is considered, if the structure is formed in two layers.

A preferred embodiment of the wall according to the invention provides that the reinforcing layer is formed as a concrete layer and a positive and / or non-positive bond between the wood or glulam or concrete layer is provided. The concrete layer used here is in particular a layer of fiber concrete or reinforced concrete. In order to take into account the expansion coefficients of wood and concrete, there is the possibility that a separating layer is arranged between the wood or glulam and the concrete layer. Thus provided is a wall made of a wood concrete composite, which combines the properties of both materials in a particularly advantageous manner. In addition, the weather resistance and thus durability of the wood or glued laminated timber wall is significantly improved by the support or layer of concrete. In order to produce a positive connection of wood and concrete, it is considered favorable if a dovetail joint is formed here. The wood layer may in this case have correspondingly shaped grooves, which are milled or introduced after the formation of the glued laminated timber or the layer formed therefrom. During the potting of the wood layer with concrete, these grooves are also poured with concrete and improve the strength between wood layer and concrete layer.

As an alternative to the positive connection, it is considered favorable if connecting means are provided for frictional connection or stabilization of the wood-concrete composite. These connecting means, for example. Bolts, webs or the like are on the one hand in the wood or glulam, on the other hand in the concrete layer.

An alternative variant of the wall according to the invention provides that here a reinforcing layer of metal, preferably steel or another stabilizing material, such as. A fiber composite material is formed and on at least one side of the reinforcing layer, a layer of glued laminated timber is applied. Alternatively, the layer of glued laminated timber can also be built on the reinforcing layer. In other words, the reinforcement layer is provided even before the glulam is formed. The individual layers of the glulam are then placed on the reinforcing layer or placed on this and thus formed the glulam on the reinforcing layer. In order to achieve an improvement in the connection between the reinforcing layer and the layer of glued laminated timber, it is considered favorable if the reinforcing layer has a fold on at least one end and the glued laminated timber is supported and / or gripped by the bent edge. This fold also offers advantages in the construction of the glued laminated timber layer on the reinforcing layer, as this provides a clear specification of the position of the glued laminated timber or of the individual layers of the glued laminated timber.

A further advantageous embodiment provides that in the reinforcing layer and the layers of glued laminated wood holes or recesses and the reinforcing layer and the layers of glulam by cross-connecting elements, in particular dowels, flat dowels, bolts, screws, pins or nails are provided in the holes or Recesses used and further improve the connection between the reinforcing layer and the wood layer.

A development of the wall provides that two provided with glued laminated timber and back interconnected reinforcing layers are provided, which are bolted together, welded, riveted or glued.

The wall can of course also be formed from a combination of a wood-concrete composite with additionally applied or incorporated reinforcing layer as described above.

The invention also includes a method of making a track section as previously described. In this case, a trench section base body is provided which has a cover surface which protrudes on both sides of the trench section base body in both directions. The roadway section main body is arranged on a support or end surface projecting on both sides of the roadway section main body in the width. The route section is then completed by placing it on both sides, in particular instead of two or more side walls on the route section main body. As a result, a two-or multi-shell construction is formed. The side walls are preferably formed from glulam which has recesses or grooves, which are in particular formed as dovetail grooves. From the layer of glued laminated wood, a layer of particular fiber-reinforced concrete is poured and thereby cast the grooves, in particular dovetail grooves with concrete. As a result, the stability of the side walls is significantly improved and higher bearing loads can be removed. Alternatively or additionally, at least one reinforcing layer, in particular made of metal, preferably steel or a fiber composite material can be provided for forming the side walls and applied on at least one side of the reinforcing layer, a layer of glued laminated wood or the layer of glued laminated timber on the reinforcing layer. The reinforcing layer has preferably at one end a fold on which the laminated timber is supported. The reinforcing layer and the layers of glued laminated timber preferably have holes or recesses into which the reinforcing layer and the layers cross-connecting elements, in particular dowels, flat dowels, bolts, screws, pins or nails are used to provide a connection between the reinforcing layer and layer of glued laminated timber.

A further possibility of producing a side wall in the method according to the invention for producing a route section provides that two reinforcing layers provided with glued laminated timber are connected to one another at the rear, in particular screwed, welded, riveted or glued. Alternatively or additionally, there is also the possibility that glued laminated wood layers provided with a concrete layer are connected to layers having a reinforcing layer.

The cover surface protruding from the line section main body preferably has an overlapping projection, while a fold or a shoulder is provided in the closing surface, which likewise projects beyond the line section main body. In the method according to the invention, the side walls are first introduced with one end into the overlapping projection and then placed against the fold or the shoulder, after which a connection of the top surface and side wall or end surface and side wall is performed. In the production of the line section conical recesses or depressions are provided in the end face in particular, or projecting conical cams are introduced, which serve to be engaged in the arrangement of the route section on a pillar or a support provided thereon with corresponding complementary complementary structures.

The invention further comprises a method for forming a multipurpose road, in particular from a plurality of road sections as described above. For this purpose, a route section is placed on at least two buttresses. The pillars have at their the track section end facing pads for the route section, with which the route sections are connected. In the supports or the support pillar facing surface of the route section preferably complementary structures are arranged. The structures guarantee that during the placement of the line section on the buttress form-fitting these are brought or engaged. The shape-complementary structures thereby guarantee a sliding of the route sections on the pillars or the conditions provided there and position it precisely the route sections. Another advantage of this is that even when replacing the route sections, eg. For revision or repairs, a new or outdated route section can be placed in the same way on the pads and a satisfactory positioning is guaranteed due to the complementary shape structures.

The multipurpose road is particularly suitable for the construction of supply or traffic routes in rough terrain or over long distances. To the construction of the multipurpose road to To simplify and to avoid the creation of additional roads or the like for the transport of material for the further construction of the multipurpose road, it is considered favorable if on an already partially assembled multipurpose road transport vehicles, with at least one route section and / or buttresses and / or other materials are loaded for the further construction of the multipurpose road, are moved to the end of the multipurpose road and are unloaded there in particular by a preferably on, next to or on the multi-purpose road mobile crane. The crane can spend the route section or the abutments or the material up to the final position. It is also possible that on an already partially assembled multipurpose road transport vehicles are moved, which are loaded with cables or lines to be laid in the cavity or on or between the side walls of the multipurpose road. These cables or lines can be removed during the construction of the multipurpose road directly from the transportable thereon trolley and installed in the route section or arranged on this. It thus eliminates the additional transport of the appropriate materials to the route construction site.

To ensure a closed transport cycle, it is provided that at the end of the already partially assembled multipurpose road, the crane transports the unloaded trolley to another route on or within the same route section or in the cavity and the trolley thus moves back to the place of loading, while another Dolly is moved to the end of the multipurpose road.

Thus provided is a multipurpose line or lines forming this under production and force absorption points, which further develops the state of the art and substantially improves the stability and load-carrying capacity of known multipurpose lines. Through the use of differently designed or produced side walls or suitable combinations thereof, a modification of the multipurpose road and the vote on the ablated bearing loads can be performed. The main use of renewable raw materials, in particular of wood, guarantees on the one hand the cost-effective, on the other hand the sustainable production process and substantially reduces the costs compared to the use of steel beams or reinforced concrete composites. However, the suitable combination of track components can ensure the same stability.

1a shows a route section 10 Essentially made of glued laminated timber 24 is constructed. The route section 10 has a total of a two-shell construction. An inner route body 11 has a top surface 12 as well as a finishing area 13 , Between deck area 12 and finishing area 13 are two inner sidewalls 21 as well as two outer sidewalls 20 arranged. In addition to the finish area 13 has the track section shown here 10 about an edition 14 (see. 4 ), on the route section 10 is attached. In the route section 10 a total of three chambers are provided. Two outer chambers are used to accommodate cables 18 , These are in particular so-called high-voltage direct current transmission cable. These are in the outer chambers of the route section 10 arranged and thus spatially separated from the inner cavity of the route section 10 , In this are pipes 17 For example, arranged for the transport of gas, water or oil. In addition, in the cavity gas-insulated power conductors 16 intended. The from the route section shown here 10 formed multipurpose road thus serves for a recording or disposal of a route 19 on the top surface 12 is arranged, on the other hand as a recording and conduction space for conductors 16 , Electric wire 18 and pipes 17 , In addition to the pipes arranged in the cavity for raw materials or electricity can here another route 19 be made available, for example, can be used for the revision of the cavity. For this purpose, rails are inside the cavity 32 laid. The on the top surface 12 arranged tracks 31 are used to move a trolley 41 who in 1a only shown in sections.

The outer side wall 20 has in the embodiment of 1a a total of three-layered construction. While an inner, the cavity facing first layer 42 out Glulam is the second, outer layer 43 in the embodiment of a concrete overlay 23 educated. Between the two layers in the exemplary embodiment was a release layer 29 arranged, showing the different expansion coefficients of the two layers 42 . 43 balances.

The in 1a shown route section 10 has a total of two outer side walls 20 that the track section 10 limit. Relative to the outer side walls 20 inside the track section 10 arranged are the two inner side walls 21 , These, too, mainly consist of glued laminated timber 24 , To both the inner sidewalls 21 as well as the entire structure of the route section 10 To stabilize, have these inner sidewalls 21 a reinforcement layer 22 on. This also has connecting elements 25 in the glued laminated timber 24 stand up and there over fasteners 26 are anchored. The glued laminated timber 24 will build the inner sidewall 21 with the reinforcement layers 22 connected. In the embodiment of 1a are the outer side walls 20 made of a wood-concrete composite, while the inner sidewalls 21 made of a composite consisting of glued laminated timber 24 and reinforcement layer 22 are formed. As an alternative to the embodiment shown here, of course, the side walls 20 . 21 be arranged reversed, ie the inner side walls 21 are made from the wood-concrete composite, while the outer sidewalls 20 one with a reinforcing layer 22 provided glulam wood 24 are formed. Of course, there is also the possibility that both inner and outer side walls 20 . 21 are formed in the embodiments shown here. In addition, the side walls 20 . 21 only made of glued laminated timber 24 being constructed. The use of a wood-concrete composite or one with a reinforcing layer 22 equipped glulam timber 24 improves the stability of the track section 10 and allows higher bearing loads on the route 19 or the use of heavier or larger sized pipes or lines in the interior of the route section 10 or the route formed therefrom.

For the production of the route section 10 becomes first an inner route basic body 11 made available. This includes the inner sidewalls 21 as well as the top surface 12 and the closing surface 13 , This route basic body 11 will be on the pad 14 (see. 4 ), the paragraphs 44 having. These are the outer side walls 20 after insertion in the in the top surface 12 provided longitudinal grooves 45 employed and thus the outer dimensions or dimensions of the route section 10 Are defined.

1b shows a detail of the inner sidewall 21 of in 1a shown route section 10 , This is made of a total of two layers of glued laminated timber 24 built up. Between the two layers of glulam 24 is a reinforcement layer 22 arranged. This consists in the embodiment of 1b from steel. Of course, there is also the possibility that here a reinforcement layer 22 is arranged from a fiber composite material or the like. At the reinforcement layer 22 are fasteners 25 arranged in the glued laminated timber 24 stand for. These fasteners 25 be in the production of the inner sidewall 21 co-sponsored. First, this is a reinforcing layer 22 provided at the adjoining the glued laminated timber 24 is built. The reinforcement layer 22 has recesses 33 on, in which the connecting element 25 is introduced so that this in the glued laminated timber 24 is built in. In addition stabilizing effect of the lanyard 26 , In the embodiment, a nail in the connecting element 25 and the boards below 40 of glued laminated timber 24 is introduced. The thus formed inner side wall 21 can then for the construction of the route section 10 be used. The use does not remain on the inner sidewall here 21 limited. Similarly, there is the possibility that the outer side wall consists of a correspondingly formed structure. Registered forces are transmitted through the reinforcement layer 22 and the glulam 24 in the edition 14 ablated.

2 shows another possible embodiment of an outer side wall 20 , which of course also inside, ie as inner sidewall 21 Can be used. This is also made of glued laminated timber 24 that with dovetail grooves 28 was provided. On the glued laminated timber 24 became a concrete pad 23 applied. The glued laminated timber 24 was for this purpose with the concrete, which is in particular fiber concrete, shed. Here were the dovetail grooves 28 filled with the concrete, so here is a dovetail spring 27 has trained. This favors the shear resistance of the two superposed layers and improves the stability of the outer sidewall thus formed 20 additionally. Also the glulam 24 , this in 2 Use is made of individual boards 40 built up. Only after the construction of the glued laminated timber 24 Here are the corresponding dovetail grooves 28 milled.

The result is a wood-concrete composite that combines the advantages of the two materials, ie the high compressive strength of the concrete is complemented by the high tensile strength of the wood. Thus, on the thus formed outer side wall 20 higher bearing loads in the with the sidewall 20 equipped multipurpose road can be applied, derived. The construction is thus stabilized overall.
