JPH05106343A - Timbering for beam mold - Google Patents

Abstract

PURPOSE:To simply install and remove a mold at a narrow position of a beam by suspending a horizontal member supporting the bottom sheathing board of a beam mold at the upper ends of the right and left stanchions, and rotatably fitting a beam side timbering supporting the side sheathing board of the beam mold to the horizontal member. CONSTITUTION:A horizontal member supporting the bottom sheathing board 2 of a beam mold is suspended on the upper end sections of the right and left stanchions 1, and multiple intermediate joint members 4 are suspended at the intermediate sections. The right and left stanchions 1 are made expandable. A beam side timbering 6 supporting a side sheathing board 5 is fitted at the center section of the horizontal member. The timbering 6 is constituted of an arm section 8 made rotatable by a fitting pin 7, a support section 9 at the tip of the arm section 8, and a slant member 10 reinforcing it, the timbering 6 is rotated to arrange the support section 9 along the outside of the sheathing board 5, and the side sheathing board 5 is supported and rotated in the opposite direction and suspended at the center section of the horizontal member. The assembling/disassembling work of the beam side timbering 6 is not required, and mold releasing can be simply performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam form support.

[0002]

2. Description of the Related Art In general, a beam formwork used in reinforced concrete construction is a weir plate made of wood or metal that is in direct contact with concrete, and a support or flap material for supporting the weir plate and fixing it at a predetermined position. It is composed of supporting works such as.

Many of these barrier plates and supporting members have a systematic structure so that they can be mechanically assembled and demolded as easily as possible. For example, the side contacting the side surface of the beam. The dam plate is formed in a horizontally elongated panel shape along the beam, and is supported by a beam-side support structure composed of many vertical and horizontal sidings.

[0004]

However, in the beam side support work as described above, when the installation intervals of the beams to be constructed are relatively large and a wide space can be secured on the beam side part, the support work of the beam support side is not possible. Installation and removal can be done without any problems, but as shown in Fig. 3, when the installation intervals of the beams are very close to each other and they are diagonal to each other, it is not possible to secure sufficient space on the side of the beam. In many cases, it is very difficult to install and remove the support work because they interfere with each other.

The present invention was proposed in order to solve the above-mentioned conventional problems, and can be easily installed even in an extremely narrow place where a sufficient space cannot be secured on the side portion of the beam to be constructed. The purpose of the present invention is to provide a support for beam formwork that can be removed.

[0006]

In the beam form supporting work according to the present invention, a horizontal member for supporting a bottom dam plate of the beam form is installed on the upper ends of the left and right columns, and the beam is attached to the horizontal member. It is configured by rotatably attaching beam side supporting works for supporting the side dam plate of the formwork.

[0007]

1 and 2 are side views of a beam form supporting work showing an embodiment of the present invention. In the figures, two right and left columns 1,1 built at predetermined intervals are shown. A horizontal member 3 for supporting the bottom dam plate 2 of the beam form is installed on the upper end,
A plurality of intermediate connecting members 4, 4 are installed in the intermediate portion.
The left and right struts 1, 1 are configured to be expandable and contractible, for example, pipe supports are used.

A beam-side supporting structure 6 for supporting the side dam plate 5 of the beam form is attached to a substantially central portion of the horizontal member 3.

The beam-side support 6 includes an arm 8 rotatably attached to a substantially central portion of the horizontal member 3 by an attachment pin 7, a support portion 9 vertically installed on the tip of the arm 8, and It is composed of a diagonal member 10 for reinforcing the supporting portion 9.

Each of the arm portion 8, the support portion 9 and the diagonal member portion 10 is constructed so as to be detachable and extendable like the strut 1, and is made of wood or steel.

The beam side support 6 rotates the mounting pin 7 to attach the supporting portion 9 to the side dam plate 5 of the beam form, and the arm portion 8 to the horizontal member 3 with a plurality of fixing bolts. 1
The side dam plate 5 can be supported by bolting it with 1,11 (see Fig. 1), and when removing the formwork, remove the fixing bolts 11,11 and hang it on the central part of the horizontal member 3. (See FIG. 2).

Therefore, if this beam form supporting work is used, the work of assembling and removing the side supporting structure for supporting the side dam plate 5 of the beam form becomes unnecessary, and the side dam is removed when removing the form. It is possible to easily remove the mold by pulling down the plate 5 right underneath. Especially, as shown in FIG. 3, the installation intervals of the beams are very close to each other, and the beams are diagonally attached to each other to support the beams. Excellent power when there is very little space to assemble.

Since the left and right columns 1, 1 are configured to be expandable and contractible, it is possible to freely adapt to different beam heights, and the arm portion 8, the support portion 9 and the diagonal member portion 10 Also, since it is configured to be expandable and contractible, it is possible to freely cope with a case where the beam width and the beam formation are changed by appropriately changing the lengths of these members.

[0014]

Since the present invention is constructed as described above, it has the following effects.

It is possible to support the side dam plate of the beam form by rotating the beam side support around the mounting pin and attaching the supporting portion to the outside of the side dam plate of the beam form, and also to support the side dam plate of the beam form. At the time of removing the frame, the beam-side support can be rotated in the opposite direction around the mounting pin and can be hung on the central portion of the horizontal member 3.

Therefore, the work of assembling and removing the side support work for supporting the side dam plate of the beam form becomes unnecessary, and when the form is removed, the side dam plate can be easily removed by pulling it down directly below. You can For this reason, since the installation intervals of the beams are very close and the beams are diagonally aligned with each other, it is very effective when there is very little space for assembling the support work on the side portions of the beams.

Further, since the structure is extremely simple, it is easy to handle and the manufacturing cost is extremely low.
