Description

  The present invention relates to a construction apparatus and construction method for a multilayer building structure in the construction field.

  When building the upper layer of a multi-layer building structure, it is necessary to lift the building member up to the upper layer. Conventionally, a fixed crane is installed inside or on the side of the building structure. We were lifting up. However, if a fixed crane is installed inside or on the side of the building structure, the installation part cannot be constructed, so the part where the fixed crane was installed must be post-constructed, and the construction period Increase in cost and cost. Moreover, in order to avoid such post-construction, it can be considered that a fixed crane is installed around a building structure. However, if a fixed crane is installed around the building structure, the distance to the suspended load increases, so it is necessary to increase the capacity of the crane compared to the case where it is placed close to each other, resulting in an increase in cost. I will.

  In addition, there is a precast method as a means for shortening the construction period in the construction of a building structure, but because the precast building material in the precast method is heavy, the load on the crane becomes larger and the precast method is adopted. However, the cost could not be reduced. Because of these problems, construction of building structures in confined areas, which are common in urban areas, is carried out by conventional methods such as rebar construction, formwork construction, concrete construction, etc. on site, which can shorten the construction period. was difficult.

  The present invention has been made in view of such a problem, and is a construction apparatus for a multi-layered building structure capable of improving the construction efficiency and reducing the cost even in a place with a small construction space such as a narrow space. It is a technical problem to provide a construction method.

  The present invention is a construction apparatus for a multilayer building structure, and is configured as follows in order to solve the above technical problem. The present invention includes a first crane that is movable in the horizontal direction and builds a building body by assembling building members, and a lifting device that conveys the first crane and building members in the vertical direction. A construction apparatus for a multi-layered building structure, wherein the lifting device mounts a mast erected adjacent to a building structure to be built and the first crane, and moves up and down along the mast. It is provided with a 2nd crane provided in a plane stand and the said plane stand, and conveying a building member in a perpendicular direction and a plane direction.

By using the construction device, the building member and the first crane are transported in the vertical direction using the lifting device, and the transported building member is transported in the horizontal direction by the second crane. Layers or two-layer housings can be constructed. According to such a construction method, since the lifting device only needs to move in the vertical direction, it is possible to use a device having a simple structure and a small capacity, and can be downsized. Therefore, the installation area can be reduced, and it can be installed adjacent to the building structure. On the other hand, the first crane transports the building members raised and lowered by the lifting device in the horizontal direction and assembles the frame. In other words, the first crane only needs to be capable of moving in the horizontal direction and constructing a frame for one layer or two layers, and therefore has a simple structure and a small capacity. And miniaturization can be achieved. Moreover, since the mast of the said raising / lowering apparatus is arrange | positioned adjacent to the building structure to be constructed | assembled, a building member can be conveyed to the vicinity of a construction location, and a housing can be constructed | assembled. Therefore, the first crane does not require an excessive capacity and is suitable.

  In addition, after building a frame for one or two layers, when building the upper layer, the first crane is moved onto the lifting device and lifted to the upper layer portion to be constructed by the lifting device. be able to. And again, it builds for one layer or two layers using the 1st crane. By repeating this, a multi-layered building structure can be constructed efficiently.

  Furthermore, since the 2nd crane is provided in the plane stand of the said raising / lowering apparatus, a building member can be conveyed using this 2nd crane. By using this second crane, the building member can be lifted easily, so that the construction efficiency can be further improved. In addition, as described above, the building members are transported in the horizontal direction on the construction floor using the first crane or the carriage. In particular, when the position to be constructed is separated from the lifting device, work efficiency can be improved by using a cart that can move in the horizontal direction. However, when the lifting device and the place to be constructed are close, if a building member is transported from the lifting device using a carriage or the like, it takes time to temporarily place the building member on the carriage or the like, and the work efficiency may be reduced. . In such a case, the construction efficiency can be further improved by transporting the building member to a place to be constructed using the second crane.

  In addition, the construction apparatus for a multilayer building structure according to the present invention includes a carriage that horizontally conveys the building members conveyed by the lifting device, a traveling rail that is a traveling path of the carriage and the first crane, It is desirable to have.

  In the present invention, by using the carriage, the building member can be constructed by the first crane while the building member is conveyed to the first crane side by the carriage. Can be done. Therefore, it is possible to improve work efficiency. In particular, it can be suitably used when the area of a plane such as a large-scale building structure is large.

  Various apparatuses can be used for the first crane and the carriage used in the present invention, but some apparatuses require a traveling rail. When using such an apparatus, it is desirable to install and disassemble the traveling rail using the first crane. The first crane is used to construct a housing, disassemble the travel rail from the constructed location, and place the disassembled travel rail on the constructed portion. Next, when the upper layer portion is constructed, since the disassembled traveling rail is placed on the upper layer portion, it is only necessary to install the traveling rail. Thus, by installing and disassembling the traveling rail using the first crane, it is possible to perform work efficiently and to reduce the work period and cost.

  Moreover, this invention is the construction method of the multilayer building structure using the above-mentioned construction apparatus, Comprising: The 1st process of installing the said raising / lowering apparatus adjacent to the structure which should be built, and the said raising / lowering apparatus are used. After performing the second step of conveying the first crane and the building member in the vertical direction and the third step of constructing a one-layer or two-layer housing using the first crane, The second step and the third step are performed.

  According to the present invention, the building method and the first crane are transported in the vertical direction using the lifting device, and the transported building member is transported in the horizontal direction by the first crane. In 1 layer or 2 layers can be constructed. And a multilayer building structure can be constructed | assembled efficiently by repeating this 2nd process and 3rd process.

  Furthermore, the construction method of the multi-layer building structure according to the present invention includes the step of installing the traveling rail using the first crane after the second step, and traveling the first crane to the location to be constructed. It is desirable to perform the step of transporting the building member to the first crane side using the carriage.

  The present invention can be suitably used for the construction of various building structures formed in multiple layers. For example, the present invention can be suitably used for a building structure in a precast method in a reinforced concrete structure. In the precast method, these precast members are assembled in the field as precast members that are assembled in advance at a factory for each of a plurality of blocks. Therefore, many building members are heavy in weight, and in the conventional construction method, the load of the first crane to be lifted is particularly large, and the increase in cost and construction period is remarkable. However, since the construction method according to the present invention constructs the housing using both the lifting device and the first crane, the load on the lifting device and the first crane is reduced even for heavy building members. It becomes possible. Therefore, the construction method of the multilayer building structure according to the present invention can be suitably used in the precast method.

  As described above, according to the construction apparatus and construction method for a multilayer building structure according to the present invention, the construction efficiency can be improved and the cost can be reduced even in a place with a small construction space such as a confined area. In addition, since the building members are lifted by the lifting device and the frame is constructed by the first crane, work can be performed in the vicinity of the building members that are suspended, and the load on each crane can be reduced. Is possible. Furthermore, even in places where construction space is small, even heavy reinforced concrete building structures can be constructed by the precast construction method, so that quality and safety can be improved. It becomes possible to shorten.

  Hereinafter, an embodiment of construction of a multilayer building structure according to the present invention will be described in detail based on the drawings. In the present embodiment, a 12-story apartment house made of reinforced concrete is constructed by a precast method. FIG. 1 is an explanatory schematic diagram of a method for constructing an apartment house according to the present embodiment, FIG. 2 is a view as viewed from an arrow A in FIG. 1, and FIG. 3 is a plan view of FIG.

A loading crane 14 as a second crane. The lifting device 1 moves the building member, the first crane 3, and the carriage 2 in the vertical direction, and places the building member on the carriage 2 by using a loading crane 14 provided on the flat table 12.

The first crane 3 is movable in the horizontal direction, and constructs a frame by assembling precast building members. Since the first crane 3 can be moved to an appropriate place in the horizontal direction to construct a frame, a smaller crane can be employed as compared with a crane in a conventional construction method. Further, the traveling rail 4 for traveling the first crane 3 and the carriage 2 is also laid and removed by using the first crane 3.

First, the plane table 12 is raised in a state where the first crane 3 is placed, and the first crane 3 is conveyed to the floor to be constructed. Using this first crane 3, the carriage 2 and the traveling rail 4 are conveyed to the construction floor. When these devices are conveyed to the construction floor, the traveling rail 4 is laid using the first crane 3 and the first crane 3 is moved to the construction site. While moving the first crane 3, the building member is lifted using the load crane 14 of the lifting device 1 and placed on the carriage 2. Using this cart 2, the building member is conveyed to the crane 3 side. Then, the frame is sequentially constructed while the crane 3 is moved backward (see FIG. 4).

  In this way, the construction of the chassis is advanced, and when the construction of the chassis has proceeded to a distance at which the building members can be directly loaded by the first crane 3, the first crane 3 is moved onto the plane table 12 of the lifting device 1. At the same time, the carriage 2 and the traveling rail 4 are placed on the upper floor using the first crane 3. And when constructing the last block in a construction floor, the 1st crane 3 is fixed to the mast 11 of the raising / lowering apparatus 1 so that it can receive reaction force. In this way, the remaining part is constructed (see FIG. 5).

  In this way, when the construction for the first floor is completed, the plane table 12 is raised with the first crane 3 placed thereon. Next, the traveling rail 4 is laid on the construction floor to be newly constructed using the first crane 3 (see FIG. 6).

  Next, the first crane 3 that has been fixed to the mast 11 is removed, and the first crane 3 is moved to a place to be constructed. Further, the carriage 2 is moved onto the traveling rail 4 (see FIG. 7). And again, a building is constructed using the 1st crane 3, conveying a building member to the crane 3 side using the trolley | bogie 2. FIG. By repeating this process, a 12-story apartment house can be constructed.
