DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake stage (hereinafter, simply referred to as an "elevator stage") installed on a scaffold for receiving materials and the like from a construction elevator. The present invention relates to a structure that is an assembled unit type and has improved workability and safety during installation.

[0002]

2. Description of the Related Art Conventionally, when a building to be constructed is a relatively high-rise building, a construction elevator is installed outside a scaffold assembled around the building to transport materials, equipment, personnel, and the like. Sometimes. However, if the construction elevator is installed directly outside the scaffold, the brace for reinforcing the scaffold or the like hinders the transfer of materials or the like directly from the elevator to the scaffold. Therefore, in general, a scaffold is not provided at a portion facing the elevator, and instead, a separate take-in stage is provided as a dedicated landing for receiving materials and the like from the construction elevator.

[0003] The seed take-in stage is completed by laying a wooden scaffold plate on a peco beam or a beam frame as a large drawing material and a single tube as a joist material, and assembled on a floor for each floor. It is.

[0004]

However, according to the above-mentioned prior art, there is a problem that a large number of parts must be connected and the assembling and disassembly of the take-in stage is extremely troublesome. In addition, since the assembling / disassembling operation itself is performed at a high place, there is a problem in terms of safety.

By the way, it is convenient and safe if a take-up stage assembled in advance on the ground can be lifted and installed and fixed on a scaffold. However, in this case, the spacing between the left and right scaffolds on which the take-in stage is to be installed does not always match the lateral width of the elevator stage, and it is rather difficult to keep the left-right spacing constant at all times due to errors in assembling the scaffolds.
Further, usually, the scaffold spacing is often narrower than the elevator stage by the size of the connecting portion, and it has heretofore been impossible to lift and install the assembled elevator stage.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an elevator stage that can be assembled and disassembled with good workability and safely.

[0007]

In order to achieve the above-mentioned object, according to the present invention, a vertical member of a scaffolding frame can be freely connected to the left and right of an assembled stage base including a beam frame, a joist frame, a flooring material and the like.

[0008]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 are a front view and a plan view of an elevator stage. The illustrated elevator stage mainly includes five members of a beam frame 1, a joist frame 2, a floor panel 3, a handrail frame 4, and a gate 5, and has a unit structure in which these members are previously assembled on the ground. In the figure, T indicates scaffolding frames provided on the left and right sides of this stage.

The structure of each member and the assembling method will be described. First, as shown in FIG. 3, a beam frame 1 is constructed by reinforcing several round pipes 1a into a rectangular body by a diagonal member 1b. A single clamp 1c is welded to five places of the upper chord material. A fixing plate 1e having a bolt hole 1d is welded to the left and right sides of the frame. Further, a mounting plate 6 for fixing the present stage to the scaffolding frame is provided on the fixing plate 1e so as to be extendable and contractible.

More specifically, as shown in FIGS. 4 and 5, the mounting bracket 6 in the present embodiment has a long hole 6 with a square pipe 6b bolted to a clamp 6a at upper and lower locations.
The slide plates 6d formed with c are welded. And this mounting bracket 6 is a slide plate 6d
With the fixing plate 1e sandwiched between 6d, bolts are inserted into the long holes 6c of the slide plate 6d and the bolt holes 1d of the fixing plate 1e, and are fixed to the left and right sides of the beam frame 1 by fastening with nuts (FIG. 1). reference). By loosening the nut, the slide plate 6c can be expanded and contracted right and left. When assembling the stage, two sets of the beam frames 1 are arranged in parallel in the front-rear direction, and are connected by the cross braces 7 (see FIG. 2).

Next, as shown in FIG. 6, three joist frames 2 are formed by welding several square pipes 2a into a rectangular shape.
b is fixed by bolts 2c, and a telescopic pipe 2d formed by inserting an inner pipe into an outer pipe is welded to five places on its lower surface. The joist frame 2 is fixed on the beam frame 1 by a clamp 1c welded to the upper chord of the beam frame 1 (see FIG. 1). Then, seven floor panels 3 are laid on the joist frame 2 fixed to the beam frame 1 (see FIG. 2), and the stage foundation is completed. The floor panel 3 is fixed to the joist frame 2 by corner fittings 8 (see FIG. 1). Further, the base plate 9 is bolted to the four corners on the floor panel 3 (see FIG. 2), and the handrail frame 4 is inserted into the projection 9a (see FIG. 1). Further, a gate 5 is clamped and fixed between the left and right handrail frames 4 to complete the elevator stage. Instead of the floor panel 3, a steel or plywood scaffold may be used as the floor material.

Next, a method of installing the elevator stage assembled on the ground on the scaffolding frame T according to the above procedure will be described. First, the mounting brackets 6 provided on the left and right sides of the beam frame 1 slide the slide plate 6d to the inside of the beam frame to reduce the amount of protrusion, and make the total length of the elevator stage shorter than the scaffold interval ( 1). In this state, the elevator stage is lifted to a target floor by a hoist or the like. Then, the mounting bracket 6 is pulled out to the outside (scaffold side) by work from the scaffolding frame side, and the clamps 6a (eight in the case of the present embodiment) of the mounting bracket 6 are connected to the vertical member t of the scaffolding frame T. Then, the installation of the elevator stage is completed (see FIG. 2).

As described above, according to the above-mentioned elevator stage, it is only necessary to lift the stage base assembled in advance by a hoist and fix it to the scaffolding frame T by the clamp 6a of the mounting bracket 6. Easy. In addition, when assembling the elevator stage or the like, there is no need to connect a plurality of members constituting the stage foundation at a high place, so that the installation can be performed safely.
Further, in the above embodiment, since the telescopic pipe 2d is fixed to the joist frame 2, if the telescopic pipe 2d is extended, the laying area of the floor panel 3, that is, the floor area of the stage foundation can be changed. . Further, since the beam frame 1 and the joist frame 2 can be separated via the clamp 1c, fine adjustment of the elevator stage can be performed in the front-back direction with respect to the scaffold to be installed. Further, in the present embodiment, since the joist frame 2 is constituted by a plurality of frame bodies 2b... 2b which can be divided, when not in use, the joist frame 2 is divided so that the storage space can be reduced and transportation can be facilitated. Furthermore, even if it is necessary to disassemble at a high place, the heavy joist frame 2 can be divided, so that it can be easily disassembled.

In the above-described embodiment, the fixing plate 1e of the beam frame 1 is used as the mounting bracket 6 by the slide plate 6d.
However, as shown in FIG. 7, the configuration may be such that the slide plate 6d is held by the fixed plate 1e. Further, the expansion and contraction structure of the mounting bracket 6 does not need to be limited to the slide plate 6d having the long hole 6c. As shown in FIG. 8, a pipe 10 that can be inserted into the upper chord 1a and the lower chord 1a of the beam frame 1 is prepared. It may be provided with a clamp 6a. Further, as shown in FIG. 9, a pipe 11 with a clamp is foldably connected to the left and right sides of the beam frame 1, and the pipe 11 is extended by a cross brace 12. May be held. Furthermore, the mounting bracket 6 may be provided on the joist frame 2 so as to be able to expand and contract. What is needed in the present invention is to assemble the stage foundation in advance from a beam frame, a joist frame, and the like on the ground, and to provide a mounting bracket that can be connected to the vertical member of the scaffolding frame on the left and right sides of the stage foundation so as to be extendable and contractible. .

The specific structures of the beam frame and the joist frame need not be limited to those in the above embodiment. The beam material can support the load of materials and equipment, and the joist frame can lay and support the floor panel. Any structure may be used. Similarly, flooring materials are not limited to floor panels, and other widely used scaffolding boards can be employed.

[0016]

As described above, according to the present invention, the elevator stage previously assembled on the ground is lifted by the hoist and fixed to the scaffolding frame, so that there is no assembling work at a high place and the safety is secured. is there. In addition, the installation of the elevator stage also requires merely extracting the extendable mounting bracket provided on the stage base including the beam frame and the joist frame from the scaffold, and fixing the clamp provided on the mounting bracket to the scaffolding frame. Therefore, the work is simple and safe. Also,
The same applies to dismantling work. Furthermore, since the elevator stage can be divided into members such as a beam frame and a joist frame after use, transportation and storage are easy.

Furthermore, since the clamp with the clamp is made extendable and contractible, the elevator stage can be fixed to the scaffolding frame even if the distance between the left and right scaffolding frames is not kept constant due to an assembly error or the like. Furthermore, since the clamp of the mounting bracket was fixed to the vertical member of the scaffolding frame,
Unlike fixing to a horizontal member, the clamp can be fixed to any type of building frame.
