Task of the present invention is, designs the composite member that a kind of pitched roof polycrystalline substance is used.When using this composite member, the roof polycrystalline substance that manufactures both had been applicable to new building, also was suitable for the reparation of outdated building.Can adopt the prefabricated component that is essentially modular size at this, and only need a small amount of member that the length and the width of the reality on roof are carried out necessary adjustment.A so-called roof or a member " length " be meant along ridge-eaves parallax direction elongation, its " width " be meant with eaves or with the elongation of ridge parallel direction.
The present invention is this task that realizes like this: the composite member as planar plate members will have two frameworks of installing at least on ridge-eaves direction, and eaves flap spare, a ridge cover piece and at least one a standard cover piece that is parallel to eaves and ridge installation is at least respectively arranged between framework.Cover piece has normal width, and the dimension width of framework should be able to make it be similar to a millboard photograph frame, and two side frame constitutes an aperture, and cornice cover piece, ridge cover piece and one or more standard cover plate can be installed in this aperture.
When supporting member length, when the length of the length of cornice cover piece or ridge cover plate and roof length need be adjusted, then only must handle, when making it be installed on the roof one width in two frameworks, one spacing is arranged each other, and this distance adapts with size of mesh opening.Best two frameworks are processed into same widths.Because all in accordance with regulations the production technology manufacturings of a lot of houses today, its building size all is unified.Because this situation, its roof length, supporting member length and cover piece length are relatively also just consistent.And, also can compensate the not too serious scale error that causes owing to different roofs projection.
For wide roof, be reduced to the normal width (preferably 3.60m) of cover piece in order to make its aperture width, then can predesignate an additional standard supporting member with a normal width.The wide whole mark that preferably equals a standard cover piece width of standard supporting member.The preferably long 6m of standard supporting member, wide 1.0m.Just on the plane width between the standard supporting member of 1.20m, constitute the size of a grid thus.Can also reach compact 30cm size of mesh opening by additional standard supporting member (for example 90cm and 60cm width) this moment.Obviously, when adjusting the width on roof, also can put into a standard supporting member as framework.
Free plane length between the supporting member can be determined by the difference between the total length of supporting member length and cornice cover piece, ridge cover piece and standard cover piece (i.e. all standard cover pieces).In order to seal the slit of existence, can adopt to have standardized width and special length-adjustable adjustment cover piece in case of necessity.
Because adopt unified size can produce a fairly large number of all the other members, only need just can determine framework and determine the adjustment cover plate by its length according to width according to the special size on roof this moment.Obviously, the normal width of cornice cover piece, ridge cover piece, adjustment cover piece and standard cover piece always equates.A good standard cover plate length is 1.20m, and width is 3.60m.Therefore, can link together each other, and a standard cover piece also can be used as cornice cover piece or the use of ridge cover piece along a plurality of standard cover plates of ridge-eaves direction.
This just provides the advantage of making: standard supporting member, ridge cover piece, cornice cover piece and standard cover piece can create by producing in batches in a large number according to modular size.Cover plate and supporting member can couple together by bolt each other.
A supporting member will have a carriage along ridge-eaves direction trend at least, and this carriage can make the bending stiffness that improves supporting member.This carriage can be made of a steel, and can be truss-like, perhaps makes " worker " type cross section, to alleviate the weight on the web.In order not hinder the attractive in appearance of supporting member, carriage can be made cavity type.
Cover plate is made from a formula, and by supporting members supports.Cover plate can have the carriage that is similar to supporting member, and in this case, this carriage is to be parallel to eaves or ridge, and can constitute very wide from the supporting type covering plate structure.
Carriage is Extension support member and cover plate not, and the roof inner room towards polycrystalline substance plane, roof can become a smooth structure face like this.Obtain the member and the additional volume of a lower height thus.
Principle of the present invention is that combined member is being equipped with supporting member along ridge-eaves direction, and these supporting members are that an end is fixed, and the weight on roof is sent on the stringer, has fixing from the supporting type cover plate on supporting member.Obviously, one very wide, have on the roof of an above standard cover piece, must be provided with a standard supporting member respectively at least.
The jointing edge of member will be designed to have a step interface with front/rear projection, or is designed to the tongue and groove connected mode, and they can be docked each other.Between member, should note sealing, particularly weather-proof sealing will be arranged in the member upper zone.Sealing can be adopted as the plasticity weather strip that separates, and is preferably made by neoprene or similar material, perhaps the coating by durable plastic material is coated on the mating face of member.
In order to satisfy house-owner, can consider for example to have roof dormer window, skylight, chimney, ventilation installation, solar energy module or similar device with the standard cover piece that has the roof system member in the individual demand of removing overhead.Owing to be standardized all, the standard cover piece of installing before also just can making is changed other standard cover piece by special roof system member afterwards.For example, when later dismounting roof, can change the standard cover piece of a sealing into a standard cover piece that has skylight or dormer window.
Adopt two compensation cover piece its advantages to be, can change the position of the standard cover piece between eaves and the ridge, for example, oldly consider window and can be installed in the breastwork height of regulation according to roof gradient and installation specification in order to make one by this cover piece.A cover piece that has skylight, chimney or ventilation installation of manufacturing may be narrower than a standard cover piece, for example narrow half normal width, but,, accurately cooperate thereby the chimney position is obtained very with the chimney position in the building by being provided with the cover piece of special cooperation in its side.
The member of composite member can be formed by pourable material such as whole manufacturing of concrete.If member is to be formed by natural polymerization material, light weight concrete construction or the manufacturing of scum silica frost concrete, then can make element structure very light.
In order to reach very good sound insulation, effect of heat insulation, the flat part of composite member can be made the multilayer shape, covering layer is arranged and place therebetween sound insulation and/or isolation layer.Covering layer can adopt such as sawdust board or lightweight concrete slab.For sound insulation will be adopted such as mineral fibers, and also to use mineral fibers and/or polyurethane foam for heat insulation.In order to enlarge the roof inner room simply, can be to modifying through the work plane of processing already towards the covering layer of roof inner room, for example with paintedly whitewash, methods such as coating or decoration surface.
According to the shape structure that further changes of the present invention, composite member also will have a cornice stringer member that can be installed in the eaves district at least, and the eaves side of supporting member just can be supported on this cornice stringer member, so just can make composite member reach accurate installation.
Supporting member is positioned at the end of ridge side, connects in the folding mode each other, and therefore, for a saddle type roof that two cornice members are installed, this syndeton has been enough.
If composite member is additional to have at least one and be positioned at the ridge district and be parallel to the ridge stringer member that ridge is installed, (the ridge side at this member upper plate shape supporting member can be fixed on the stringer member) then is of great benefit to for disconnected supporting member.This situation of in the end mentioning, supporting member is positioned at the ridge side end can cut into the oblique angle, like this, just can dock each other in they of ridge district.Another kind of situation is, is positioned at the ridge district ridge member that a cross section can be installed is wedge shape, the interconnective slit therebetween of sealing simultaneously of this member and supporting member.The ridge member also can constitute the supporter of the ridge pantile that need lay simultaneously.The stringer number of packages order of composite member and layout are generally unrestricted, depend on roof shape, and for example, for the pentroof of an assembling, composite member may need four or more some more stringer member.
The stringer member of composite member is solid, is for example formed by steel, concrete, timber or composite material manufacturing.If the stringer member is made by hollow profile, then its structure is very light and very stable again.This structure also has attendant advantages: the pipeline that can lay electric, coal gas, water, exhaust or similar object in the stringer member.
Stringer member cross section can be not quite similar, and so just can make the ridge stringer member of installing in the ridge district make a cross section of fitting mutually with it according to the roof gradient, as triangle.
But, when the cross section of purlin part then is of great benefit to when circular: all supporting members of installing along ridge-eaves direction all the time can be tangent with the stringer member under different roof gradients.A kind of like this stringer member just can be made tubulose, and has the hole row of the slot that tangentially distributes.A supporting member meets at right angles with the Connection Element (for example bolt) that comes out from its inner surface, and these connectors can be encased within the slotted hole of stringer member, supporting member is adopted with the stringer member be threaded.
Support on the stringer member preferably places position between the supporting member, and ridge cover piece and eaves cover piece can not be on the stringer member like this, but can only be bearing on the supporting member.Support member has a smooth upper surface that can lean against on the planar plate members, and a concave bottom surfaces that adapts with the bending of stringer member is arranged.
If when having the gable member (this gable member shape is equivalent to the cross sectional form on the roof of manufacturing), then can begin to carry out the installation of whole under-roof structure from the top edge of the superiors according to another kind of structural group component of the present invention.For simple saddle type roof, the gable member can be made (for example) and see the leg-of-mutton finished product member gable of composition from the front.In order to slow down the transportation problem of heaviness and very big gable member, gable spare can be assembled by dividing member.The gable member also may have window, for example has a very large-area triangle gable window.According to the layout and the number of window, can produce the gable member in professional mode.The gable member also can be made moulding like this, for example, and for the combined type pentroof or roll over the roof again, the section configuration of gable member then given in advance.
For simple pitched roof, composite member has one and is positioned at positive triangular ramp gable member, and it correspondingly leans on the base on inclined-plane, so flat bed board just can lay to coverage rate, promptly on the gable sidewall of building.See between from the top view direction by ridge end lead-out wire, eaves and ansa, pitched roof has a leg-of-mutton side, its benefit is, when leg-of-mutton initial mating cover piece was arranged in the composite member, then these cooperated cover pieces can completely cover surface between framework and the oblique gable respectively.In this case, be to descend suddenly by the roof to lighting the framework that rectangle is installed.
For rugged shape pitched roof, composite member can have its front be about leg-of-mutton, tiltedly gable spare and trapezoidal second adjust cover piece by the pinnacle constituted a deformity that is the angle of inclination towards ridge, these are adjusted cover pieces and fill up plane between framework and the oblique gable member of deformity respectively, still will install rectangular frame being positioned at the unexpected drop point in roof in this case.
When installing, for example when having ranks transverse to the partition wall ridge and be installed on the skeleton, gable spare can be installed on the partition wall in each ranks house, can save the stone-laying of gable thus.Also of this sort when repairing the outdated building thing, mostly be the fire prevention wall because be positioned at the partition wall of adjoining building, the wall intensity than tail eaves side on its structure is big.Gable spare can be fixed with crab-bolt or angle steel respectively, thereafter again by the stringer strengthening member.
A such structure cornice stringer member in this case: it want to bear the self-supporting supporting member cause, along the component of the lateral force of tail eaves directive effect.These power are sent on the relevant gable spare with the connection of gable spare through cornice stringer member.At this moment, the vertical stress component with respect to roof gravity is to be incorporated in the gable wall by gable spare.Like this, the eaves abutment wall wall of building just has not been subjected to the load that applied by the roof.Therefore the eaves side does not just need the load bearing wall of building yet, for example this moment a glass metope can be installed.Same horizontal component is also born by gable spare, does not therefore also just need stay column.
For the secured stringers member, the edge of gable member has the end that the supporting of certain intervals is used for placing the stringer member.This linkage is considered the advantage of two aspects: the first, can bear around the moment of torsion of purlin part longitudinal axis, and this moment of torsion is not produce owing to lateral force in the stringer member and component center along the eaves directive effect do not overlap.Second aspect is, can make being connected between gable spare and the stringer member reach accurate cooperation all the time by supporting.Because the geometry of linkage is tightly to cooperate with the stringer element cross-section, therefore transmission that for example combination by shape just can realizable force.Linkage can guarantee can make these stringer members not transmit power simultaneously above the unsettled cross-ties cover plate at building all the time at the cornice stringer member that install in the cornice zone to the spacing between the edge of gable spare.As long as when the roof is very wide, just need additional support about purlin row member middle part greatly.When the roof is narrower, can not need cornice stringer member in cornice cover piece district, such gable member only just has one section cornice stringer member in the supporting member district.In this case, a cornice stringer member part is preferably made the short fixed cantilever of an end, and it can connect with gable spare agley.
Linkage can be made such as groove, groove or can be placed to the structure of the fastener formula that gable spare inner surface gets on.Fastener can be with a flange that can be installed to gable spare, and half housing of vertically arranging with flange or gable is arranged, as the linkage of stringer member.Half housing and stringer member can interconnect by pin.Like this, when making the roof polycrystalline substance, can fix as soon as possible.Obviously, a ledge that exposes from its inner surface also should be arranged as linkage on gable spare.The upper side of composite member planar plate members is equipped with the roof lath through processing, like this, can be after installing, at once just can waveform push up watt cover it above.
If the upper side of planar plate members has the projection with the ridge runs parallel, and these projections are to arrange with the spacing of roof lath each other usually, then can directly cover planar plate members without roof lath.
If the upper side of plate type member has and the corresponding moulding of the shape of roof pantile, then can saving take the more work that covers with pantile, and be unlikely to lose and cover the interested image appearance of this people of making of pantile.
The upper side of planar plate members also can be provided with path, roof material, and its covering layer can be made in advance.Preferably consider to adopt the goods that to guarantee to seal up flat roof as path, roof material.
Be furnished with a roof groove if supporting member and cornice cover piece are positioned at its cornice side area, bottom, roof rain-proof structure then can promptly be installed.When assembling, as long as roof groove various piece has been coupled together each other hermetically.If the cornice side of supporting member and cornice cover piece has an angle up, then can produce an especially simply structure, after installing, only need surpass the band whole width of eaves, that make by path, roof material to one and be routed in the groove that constitutes therefrom just.
