Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for assembling beams and columns that support a scaffolding floor in high-altitude scaffolding when constructing a structure, such as a factory or warehouse.

(Prior Art) Conventionally, when constructing a high-altitude scaffolding for constructing the roof of a structure such as a factory or warehouse, pillars were erected at appropriate intervals along opposing walls on both sides. However, a method has been adopted in which beams are erected and assembled between the ends of each column, and a scaffolding floor for work is erected between the upper surfaces of the opposing beams.

(Problem to be Solved by the Invention) According to the above method, when a beam is erected between the upper ends of each column, the upper end of each column and the beam must be connected at a high place. First, there were many dangers during the work, and the positioning of the pillars and beams had to be done at high places, resulting in poor workability.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to reduce work at high places and improve safety and workability.

(Means for solving the problem) In order to achieve the object, the technical means taken by the present invention is to separate the first and second connecting members 7a and 7b with the beam member 10 at one end in the column length direction. Pillar material 9
is arranged lying down on the ground with the first connecting member 7a higher than the second connecting member 7b, and a beam 10 having a rectangular cross section and round bars 2 placed at each vertex position is attached to the pillar 9. The first connecting member 7a is rotatably connected to one round bar 2 of the beam 10 from the side thereof, and then the beam 10 is placed horizontally from the ground. After floating the column 9 and positioning it directly below the beam 10 through rotation around the round bar 2 to which the first connecting member 7a is connected, the second connecting member 7b is placed under the beam 10. The other round bar on the side 2
The pillar material 9 is connected to the beam material 10 and the pillar material 9 is assembled to the beam material 10.

(Function) In the present invention, the pillar material 9 is initially arranged in a recumbent state on the ground, and after the beam material 10 is arranged perpendicularly to the pillar material 9 in plan view, the first connecting member 7a is connected to the beam material 10. It is rotatably connected to one round bar 2 from its side. Therefore, if the beam 10 is then placed in a horizontal state and lifted off the ground, for example, as shown in FIG. It rotates naturally, and the pillar material 9 can be placed in an upright position.

Then, by positioning the pillar 9 directly below the beam 10 and connecting the second connecting member 7b of the pillar 9 to the other round bar 2 below the beam 10, A beam member 10 is assembled and fixed to the upper end of the vertical column member 9.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 3, reference numeral 1 is a beam structural member used in the present invention, and in this embodiment, the beam structural member 1 is a cylindrical pipe material (round bar) placed at each vertex of a square. 2, a connecting member 3 that connects each pipe material 2, and joining flanges 4 provided at both ends of each pipe material 2. The connecting member 3 is made of a pipe material, a channel material, or the like, and is provided in a truss structure extending between two adjacent pipe materials.

The beam structure member 1 has a hollow shape with a space 5 formed therein. As shown in FIG. 3, the joining flange 4 is formed into a circular shape, and bolt insertion holes 6 are formed at predetermined intervals in the circumferential direction on the outer periphery.

First and second connecting members 7a and 7b made of H-shaped steel are fastened to the joint flange 4 at one end of the beam structural member 1 with bolts 8 across the pair of joint flanges 4, respectively. In this way, a long column-shaped column 9 is formed which has first and second connecting members 7a and 7b with the beam 10 spaced apart from each other at one end in the column length direction.

Reference numeral 10 designates a beam material also made of the beam structural member 1.

In this embodiment, as shown in FIGS. 1 and 2, the pair of pillars 9 are in a recumbent state and the first connecting member 7a is positioned higher than the second connecting member 7b. The beams 10 are arranged parallel to each other and spaced apart from each other on the ground, and the beams 10 are arranged orthogonally on the ground across the connecting members 7a and 7b of the pillars 9. It is connected to the first connecting member 7a on the upper side of each pillar 9 in a holding manner using two U-shaped bolts 11.

Therefore, at this time, the ends of the two pipe members 2 on the upper side of each pillar member 9 are connected to the first connecting member 7a and the U-shaped bolt 11 provided on the first connecting member 7a, as shown in FIG. It is rotatably connected to one pipe material 2 on the beam material 10 side from the side via the pipe material 2 .

Next, as shown in FIG. 1, if the beam material 10 is horizontally lifted upward using a wire 12 or the like by a lifting machine such as a crane, the pipe material 2 is held by the U-shaped bolt 11. Since they are connected in a shape, only the pillars 9 are rotated relative to each other around the pipe material 2, and each pillar 9 is made to stand upright.

Then, through the relative rotation, the pillar material 9 is moved to the beam material 1.
0, the two pipe members 2 on the other side of the beam member 10 and the second connecting member 7b of the column member 9 are brought into contact with each other, and the pipe members 2 and the connecting member 7b thereof are brought into contact with each other. As described above, by connecting with U-shaped bolts 11, the scaffolding floor support frame 13 assembled with the beams 10 and pillars 9 that support the scaffolding floor 16 can be constructed. And, as shown in Figure 1,
Opposing the scaffold floor support frame 13, another scaffold floor support frame 13 similarly constitutes a frame, and a support pipe 14 is appropriately constructed between both scaffold floor support frames 13, and a support pipe 14 is installed as appropriate on the support pipe 14. A safety net is appropriately provided on the safety net, and a scaffolding board 15 is provided on the safety net, and a scaffolding floor 16 at a high place is constructed here.

Incidentally, reference numeral 17 denotes a brace appropriately provided between each of the pillar members 9.

In this way, according to this embodiment, when constructing the scaffolding floor support frame 13 that supports the scaffolding floor 16, one side of the connection between each column 9 and the beam 10 can be made on the ground, and only the other side can be connected. Since the work is carried out at high places, the connection work at high places can be halved, improving safety and workability. Further, since the initial connection between each column 9 and the beam 10 can be performed on the ground, and the positioning can be easily performed, workability can be improved.

Furthermore, according to this embodiment, the pillars 9 are rotatably connected using the cylindrical pipes 2 placed at each vertex position of the beam structural member 1, so there is no waste in the structural members. Moreover, since the pipe material 2 is cylindrical and connected to the pipe material 2 via the U-shaped bolt 11, the work is easy and the pillar material 9 can be smoothly moved when the beam material 10 is lifted. There is also the advantage that rotation is realized.

As shown in FIG. 1, with only both beams 10 constituting the opposing scaffolding floor support frames 13 lifted, the scaffolding floor 1 is placed between the upper surfaces of both beams 10.
6 and lift both beams 10 upward at the same time, both scaffolding floor support frames 13 can be constructed at the same time.
Furthermore, in this case, the construction work of the scaffolding floor 16 can be performed at a low position, and the U-shaped bolts 11 can be installed at a high position.
can also be attached from the scaffold floor 16, further improving workability and safety.

(Effect of the invention) As explained above, according to the present invention, the pillar material 9
One side of the connection between the beam 10 and the beam 10 can be performed on the ground, and it is sufficient to connect only the other side at a high place, so the work to connect the beam 10 and the column 9 at a high place is halved, improving safety and Work efficiency can be improved.

In addition, since the initial connection of each column 9 and beam 10 is performed on the ground, alignment of these members can be done more easily on the ground than before, and from this point of view as well, workability can be improved. can.
