Description

  The present invention relates to a system for constructing an outer wall portion of a building, and more particularly to a construction system suitable for application to large-scale repair work for an outer wall portion of an existing building.

  As is well known, when a building is constructed, a temporary scaffold is usually installed to cover the entire building, and a steel framework scaffold is the most common as the temporary scaffold. However, when the framework scaffold is erected from the ground surface, its installation height is naturally limited, and it is difficult to apply it to the construction of high-rise buildings that usually exceed 45 m.

  Also, in recent years, large-scale renovation work may be performed to completely repair or renovate the outer wall while using an existing building. In such a case, temporary scaffolding may be provided. It is not preferable to install a conventional general framework scaffold so as to cover the entire existing building because the usability of the building under construction is greatly impaired, and lighting and ventilation are hindered.

  When the framework scaffold cannot be installed as described above, or when it is not preferable to install the framework scaffold, a gondola scaffold is often adopted instead. The gondola scaffolding is installed by suspending and supporting the gondola from the top of the building so that it can be moved up and down along the outer wall (and moving in the horizontal direction as needed). In this way, various operations are performed on the outer wall from the top of the gondola, and it is widely used when constructing a high-rise or super-high-rise building or when performing various operations on the outer wall of an existing building.

  By the way, in the case of using a gondola scaffold, it is common to load various materials necessary for work on the gondola together with the workers and transport them to the work position, but ordinary gondola is loaded with very large materials or heavy materials In general, work with gondola scaffolding is generally limited to light work such as window surface cleaning, inspection and inspection of the outer wall, sealing work and painting work on the outer wall, etc. It was difficult to apply to full-scale construction such as mounting of outer wall panels, window glass, sashes, etc. When dare to perform such full-scale work on the gondola scaffolding, a crane for material lifting is separately installed on the roof or outside of the building, and the crane lifts the material to the working position by crane operation. After guiding and positioning, work is performed from the gondola, but using such a gondola and crane together is inevitable, so there is a significant restriction in construction and efficient operation. That work is not something you can expect.

In addition, in order to efficiently transport materials when using a gondola scaffolding, Patent Document 1 has a gondola body supported by a crane and a lifting mechanism for lifting a material holding unit on the gondola body. A construction gondola has been proposed in which materials are loaded into a material holding unit and lifted up to just below the gondola body by a lifting mechanism.
JP 2003-268968 A

  In the construction gondola shown in Patent Document 1, the lifting mechanism for lifting the material is indirectly lifted by the crane via the gondola body, so that both the gondola body and the material are used as the crane. In addition to the need to have a scale capable of simultaneously lifting, the operation of the gondola main body and the operation for material lifting cannot be made completely independent. Construction efficiency is not obtained.

  In view of the above circumstances, an object of the present invention is to provide an effective construction system capable of efficiently performing work on an outer wall portion by a gondola and material conveyance necessary for the work.

  The invention according to claim 1 is a construction system for constructing an outer wall portion of a building, wherein a gondola on which an operator is boarded can be moved up and down along the outer wall portion from a temporary support frame installed on the upper portion of the building and moved horizontally. It is provided with a transport means for supporting and suspending various materials for construction of the outer wall section between the ground surface section and the work position along the outer wall section, and the transport means is mounted on the support frame. Traveling with a structure in which a material is suspended and supported by a wire from a trolley that travels in a horizontal direction along a provided rail, and the material is transported horizontally by traveling the trolley and the material is vertically transported by winding and unwinding the wire. It is a type conveyance mechanism.

  The invention according to claim 2 is a construction system for constructing an outer wall portion of a building, wherein a gondola on which an operator is boarded can be moved up and down along the outer wall portion from a temporary support frame installed on the upper portion of the building and moved horizontally. It is provided with a conveying means for supporting and suspending various materials for construction of the outer wall portion along the outer wall portion between the ground surface portion and the work position, and the conveying means comprises the material on the ground surface. Vertical conveying means for vertically conveying between the section and the upper part of the building, and horizontal conveying means for horizontally conveying the material delivered between the vertical conveying means at least in the upper part of the building, the horizontal conveying means comprising a support frame It is a traveling type transport mechanism that is configured to suspend and support a material by a wire from a trolley that travels horizontally along a rail provided on the rail, and to transport the material horizontally by traveling the trolley. To.

  A third aspect of the present invention is the construction system according to the second aspect of the present invention, wherein the vertical conveying means is a temporary lift that mounts materials and moves up and down along the outer wall portion.

  Invention of Claim 4 is the construction system of invention of Claim 2, Comprising: A vertical conveyance means suspends and supports material with a wire from the winding machine installed in the upper part of a building, and is a lifting mechanism of the structure which raises / lowers In addition, the traveling transport mechanism as the horizontal transport means is characterized in that the material is suspended and supported by a wire from a hoist installed in the upper part of the building via a trolley.

  Invention of Claim 5 is the construction system of invention of Claim 4, Comprising: The lifting mechanism as a vertical conveyance means suspended and supported material through the trolley, and provided this trolley in the support frame It is possible to move in a direction in which the support arm separates from the building, and by moving the trolley, the material can move in the direction to separate from the building.

  The invention according to claim 6 is the construction system according to claim 5, wherein the lifting mechanism as the vertical conveying means is a vertical conveying of material by a guide wire stretched between the support arm and the ground surface portion. It is the structure which guides.

  The invention according to claim 7 is the construction system according to any one of claims 1 to 6, wherein the suspension scaffold is suspended and supported from the support frame to the lower position of the gondola, and at least around the work position. The covering curing net is suspended from the support frame and installed.

  According to the present invention, it is possible to carry out the material conveyance work by the conveyance means independently of the work on the gondola, and therefore, the material conveyance is more efficient than when the material conveyance is performed by the crane or the gondola itself. It is possible to carry out construction on the outer wall portion in the upper part of the building efficiently.

  In addition, the material is transferred by a gondola in the upper part of the building with the vertical transport in the vertical direction and the horizontal transport in the horizontal direction independent, so that the transport distance is large or heavy. Even when it is long, material conveyance can be performed efficiently. In particular, the conveyance efficiency can be sufficiently increased by performing vertical conveyance by a temporary lift or a wire-type lifting mechanism and performing horizontal conveyance at the upper part of the building by a traveling conveyance mechanism.

  In addition, it is possible to simplify the support frame by installing the hoisting machine in the lifting mechanism and traveling transport mechanism at the top of the building, and the lifting mechanism can change the lifting position of the material to the direction of separating from the building Or by providing a guide wire for guiding the vertical conveyance, the vertical conveyance can be performed more stably and at a high speed. Furthermore, if the suspension scaffold and the curing net are suspended and supported from the support frame, work safety at a high place can be ensured without any trouble.

  1 to 2 show a first embodiment of the present invention. The construction system according to the present embodiment is an application example in the case where the outer wall of an existing building 1 of a middle-level is completely renewed. A temporary support frame 2 is installed on the roof of the building 1 and the gondola 3 Is supported so as to be movable up and down and horizontally movable, and various materials 4 such as outer wall panels are transported from the ground surface to the working position by a traveling transport mechanism 5 as a transport means.

  The support frame 2 is made of steel and is installed so as to project from the roof to the outside of each outer wall surface. The gondola 3 and the trolley 6 in the traveling transport mechanism 5 are moved horizontally in the lower part of the projecting portion. Rails 7 and 8 are provided horizontally along the outer wall surface.

  The gondola 3 is suspended and supported by a wire 9 from a rail 7 so that it can be moved up and down and moved horizontally, and an operator rides on this and moves to a desired work position to perform various operations related to the construction of the outer wall. Is.

  The travel type transport mechanism 5 as a transporting means for the material 4 is one that supports the hook block 11 by a wire 10 from a trolley 6 that can travel along the rail 8, and lifts the material 4 and transports it in the vertical direction. In addition, the trolley 6 is caused to travel along the rail 8 so as to be conveyed in the horizontal direction. The trolley 6 in the traveling transport mechanism 5 may be an electric type, and a hoisting machine may be mounted on the trolley 6 so that the trolley 6 itself functions as a traveling hoist (so-called terha). Since the weight of the machine needs to be estimated in the rail 8 and the support frame 2, the hoisting machine is installed on the roof, and the wire 10 is guided to the trolley 6 through the sheave installed at an appropriate position. In that case, since the weight of the hoisting machine is not applied to the rail 8 or the support frame 2, the configuration thereof can be simplified.

  In addition, a suspension scaffold 12 is suspended and supported from the support frame 2 at a position below the gondola 3, and a curing net 13 is attached between the suspension scaffold 12 and the support frame 2, and the suspension scaffold 12 and the curing net are attached. 13 is suspended and supported from the support frame 2 so as to be able to be raised and lowered so that its installation position can be changed according to the progress of construction. The suspension scaffold 12 can suitably employ a net or a lightweight expanded metal for the main purpose of drop curing. In any case, as shown in FIG. 2, an opening 14 for allowing the material 4 to be vertically conveyed by the traveling conveyance mechanism 5 is secured at a key point of the suspension scaffold. The curing net 13 is mainly intended for drop curing, and may cover the entire upper part of the suspension scaffold 12 as shown in the figure, but may be provided so as to cover at least the work position and its periphery.

  As described above, in the construction system of the present embodiment, the suspension scaffold 12 is installed below the work position, the curing net 13 is attached above the suspension platform 12, and the gondola 3 is moved inside thereof to obtain the gondola 3 as desired. The various materials 4 necessary for the work there are vertically transported from the ground surface by the traveling transport mechanism 5 and are transported as they are to the work position. The material 4 is used to perform various operations related to the construction of the outer wall.

  Therefore, in the construction system of this embodiment, even a large and heavy material 4 such as an outer wall panel can be efficiently transported to the position where it should be installed by the traveling transport mechanism 5, and the gondola 3 The upper worker can concentrate solely on the work of attaching the material 4 that has been conveyed without being involved in the material conveyance. That is, in the construction system of this embodiment, the conveyance work of the material 4 and the work on the gondola 3 can be performed completely independently, compared to the case of using the conventional gondola scaffold shown in Patent Document 1. Simplify work and improve workability. In addition, there is no restriction on construction due to interference between the crane and the gondola as in the case of lifting materials by separately installing cranes on the rooftop or outside, so that excellent construction efficiency can be obtained as a whole. is there. Of course, the suspension scaffold 12 and the curing net 13 can ensure work safety at high places without any problem, and the usability is greatly impaired as in the case of covering the entire building surface with a conventional framework scaffold. There is no sacrifice of lighting or ventilation.

  As shown in FIG. 1, the gondola 3 and the traveling transport mechanism 5 may be suspended and supported from the common support frame 2, but when the weight of the material 4 to be transported is large, for example, FIG. As shown in (a), the supporting frame 2A for supporting the traveling transport mechanism 5 is used as a main frame, and the subframe 2B for supporting the gondola 3 is assembled thereto, or the traveling frame as shown in (b). The support frame 2A of the transport mechanism 5 and the support frame 2B of the gondola 3 may be provided independently.

  4 to 5 show a second embodiment. This is a suitable application example when the building 1 is a high-rise building or a super-high-rise building. The difference from the first embodiment is that the conveying means for the material 4 is composed of a vertical conveying means and a horizontal conveying means. The other points are basically the same as those in the first embodiment. That is, in a high-rise or super-high-rise building 1, the required lift for transporting the material 4 in the vertical direction is naturally increased, and the transport time required for one transport is also increased. Rather, it is not efficient to perform both vertical conveyance and horizontal conveyance by one conveyance means. Therefore, in the present embodiment, the vertical transfer and horizontal transfer of the material 4 are performed independently by the vertical transfer means and the horizontal transfer means, and the material 4 is delivered between them at the upper part of the building. From the gondola 3.

  That is, as shown in FIG. 4, also in this embodiment, like the traveling transport mechanism 5 in the above-described embodiment shown in FIG. 1, the traveling transport that supports and transports the material 4 from the trolley 19 by the wire 20. Although the mechanism 21 is provided, this is mainly provided as a horizontal conveyance means for performing horizontal conveyance in the upper part of the building, and the vertical conveyance from the ground surface to the upper part of the building is independent of the vertical conveyance means. The temporary lift 22 is used.

  The temporary lift 22 in this embodiment is composed of a rail 23 attached to the outer wall surface of the building and fixed to the inside of the suspension scaffold 12 and a cage 24 that is guided thereby to move up and down. By loading and raising 4, the material 4 is vertically conveyed to the upper part of the building 1 through the opening 14 secured at the important point of the suspension scaffold 12. In the present embodiment, the traveling transport mechanism 21 and the gondola 3 are brought close to the material 4 transported up to the upper part of the building by the temporary lift 22, and the traveling material transport mechanism 21 is manually moved from the gondola 3 by the worker. The material 4 is transported horizontally to the working position by the traveling transport mechanism 21 and also transported in the vertical direction as necessary, and the gondola 3 is also moved to the working position and works there. .

  In the second embodiment, since the vertical conveyance and horizontal conveyance of the material 4 are performed independently, it is possible to perform the vertical conveyance and the horizontal conveyance simultaneously in parallel, and a large and heavy material 4 is also temporarily installed. Since the vertical transfer can be performed stably and quickly by the lift 22, the transfer efficiency is improved more than in the case of the first embodiment, particularly when the material 4 has a large body weight and a long transfer distance. It is possible, and it is more preferable when the building 1 is a high-rise building or a super-high-rise building.

  Next, FIGS. 6 to 13 show a third embodiment. FIG. 6 is a schematic diagram showing the basic configuration of the construction system according to the third embodiment, which performs the vertical conveyance and horizontal conveyance of the material independently as in the case of the second embodiment. The traveling transport mechanism 31 as the horizontal transport means is configured to lift and transport the material 4 by the wire 30, but as the vertical transport means, the material 4 is lifted by the wire 32 and the lifted material 4 is moved to the building. Thus, a lifting mechanism 33 that is slightly moved also in the direction of separation and contact is employed. In the third embodiment as well, the gondola 3, the suspension scaffold 12, the curing net 13, and the support frame 2 that supports and supports them are basically configured in the same manner as in the first and second embodiments. Since it is good, description about them is omitted, and illustration thereof is also omitted in FIGS.

  The construction system of the third embodiment will be specifically described below with reference to FIGS. In the schematic diagram shown in FIG. 6, the traveling transport mechanism 31 as the horizontal transport means and the lifting mechanism 33 as the vertical transport means are shown only on one outer wall surface, but in this embodiment, For the entire outer wall surface of the building 1, as shown in FIG. 7, four traveling transport mechanisms 31 as horizontal transport means are installed over the entire circumference of the building, and a lifting mechanism 33 as vertical transport means. Two sets are installed at the corners of the building 1 so as to be shared with the outer wall surfaces in two directions.

  That is, the lifting mechanism 33 as the vertical conveying means in the present embodiment is a gate-shaped support having two pairs of support arms 34 projecting in two directions toward the outside of the building 1 as shown in FIGS. Frames 35 are installed at the corners of the roof, and the electric trolleys 36 are moved to the lengths of the support arms 34 (that is, in the direction of coming into contact with the building 1) as shown in FIG. The hook block 37 is suspended and supported by the wire 32 from each pair of trolleys 36 and the material 4 such as an outer wall panel is lifted through the hook block 37. Then, as schematically shown in FIG. 12, the wire 32 is routed between the two trolleys 36 and the two hook blocks 37 through a large number of sheaves 39 from the hoisting machine 38 installed on the roof, and the hoisting machine 38 The trolley 36 and the trolley 36 are linked and controlled so that any trolley 36 can be selectively moved along the support arm 34 and any hook block 37 can be selectively raised or lowered. Thus, the material 4 can be lifted, that is, vertically conveyed along one of the outer wall portions.

  As shown in FIG. 12, the hoisting machine 38 is of an endless type, and a wire reel 40 for winding up the surplus wire 32 is attached thereto. Reference numeral 41 denotes an overload prevention device attached to the end of the wire 32. Further, as shown in FIGS. 9 to 10, a guide wire 42 is stretched vertically between the distal end portion of the support arm 34 and the ground surface portion, and the hook block 37 is guided by the guide wire 42. It can move up and down stably.

  According to the lifting mechanism 33, when the material 4 is lifted, the trolley 36 is positioned on the distal end side of the support arm 34 and fixed there, so that the lifting position of the material 4 is shown in FIG. As shown by the solid line, it can be sufficiently separated from the outer wall, so that it is possible to reliably prevent the material 4 from coming into contact with the outer wall due to swinging during lifting, and capable of sufficiently high-speed conveyance. is there. Further, when the lifted material 4 is transferred to the traveling transport mechanism 31 as the horizontal transport means in the upper part of the building, the material 4 is slightly moved to the building side as shown by the broken line by moving the trolley 36 to the building side. Since the material 4 can be moved horizontally and thereby the material 4 can be sufficiently brought close to the traveling transport mechanism 31, the delivery operation can be performed easily and safely.

  On the other hand, the travel-type transport mechanism 31 as the horizontal transport means in the present embodiment is provided with a rail 46 at a position protruding from the support frame 45 installed on the roof to the outside of the outer wall surface, and can be driven along the rail 46. The hook block 48 is suspended and supported by the wire 30 from the trolley 47 of the type. In this embodiment, as shown in FIG. 13, an endless hoisting machine 49 and a wire reel 50 are installed on the roof, and from there The wire 30 is routed between the trolley 47 and the hook block 48 via a number of sheaves 51, and the material 4 is mainly conveyed horizontally by controlling the hoisting machine 49 and the trolley 47 in an associated manner, and In the upper part of the building, it can also be transported in the vertical direction.

  Also in the third embodiment, the material 4 is lifted to the upper part of the building by the lifting mechanism 33, and the material 4 is transferred to the traveling transport mechanism 31 by the work from the top of the gondola 3 and further transported horizontally. It is possible to efficiently carry the material 4 to the work position and work from the gondola 3 at the work position.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the specific configuration of the gondola, each transport means, the support frame, and other elements is subject to construction. Various design changes and applications can be made without departing from the scope of the present invention, depending on the form and scale of the building, the contents of work to be performed, and the like.

  For example, the above embodiment is an application example in the case of renewing the outer wall part for an existing building, especially when various materials are transported from the ground part to the upper part of the building in order to attach a new outer wall panel to the existing building. However, it goes without saying that each transport means can transport in both directions between the ground surface and the top of the building, for example, when dismantling from an existing building is transported to the ground surface. It can be efficiently carried out in the reverse procedure by each of the above conveying means.

  Further, the present invention is not only applied to the renovation work of an existing building, but also can be applied to a new construction work of a high-rise or super-high-rise building in which a framework scaffold cannot be installed when a new building is constructed. In that case, the support frame for hanging and supporting the gondola and the transport means should be installed on the rooftop floor where construction has been completed, or it may be installed on the middle floor above the building and appropriately replaced to the upper floor as construction progresses .

  Further, in the above embodiment, a single gondola is installed on each outer wall surface, but it is of course possible to install a plurality of gondola on each outer wall surface as needed, and the form of the building, the contents of work, the shape of the material For example, an L-shaped, concave, or two-story gondola may be used in accordance with the size, etc., and the material between the vertical conveying means and the horizontal conveying means is separate from such a gondola. It may be possible to provide a dedicated gondola to carry out the work. Further, in order to prevent the gondola from swinging during work and to improve stability, it is preferable to provide a gondola support mechanism that can be connected and fixed to the building during work and can be released during movement. If there is no need for a suspension scaffold or a curing net, they can be omitted.
