Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improved scaffold for assembling, and more particularly to providing an assembling scaffold having a support member provided with a pressing and clamping member that is screwed in a horizontal direction. .

[Prior Art] Conventional scaffolds used for construction work were assembled from the ground. Therefore, in the construction work using this scaffold, it is necessary to collect a large amount of materials to make the scaffold, and it takes time and labor to assemble the scaffold and dismantle the scaffold after the construction work is completed. It was In particular, the use of this conventional scaffolding for the construction work of high-rise buildings consumes a great deal of scaffolding material and the time and labor for assembling the scaffolding, so in the construction work of high-rise buildings this conventional scaffolding Was extremely lacking in practicality. In addition, since the exterior work and repair work of a building are performed on a part or several places of the building, and it is desired that this work can be performed easily, the exterior work of the building and the like are The scaffold was impractical.

Therefore, for example, as in the scaffolding device described in Japanese Utility Model Publication No. 57-55873, an assembly scaffold has been developed in which an anchor is previously driven into a floor or a beam of a building and a pipe material or the like is assembled to the anchor. According to this, unlike the conventional scaffolding, it is not necessary to construct the scaffolding frame from the ground, so that the scaffolding material can be reduced, and the labor for assembling and disassembling the scaffolding can be omitted. The scaffold is also practical in the construction work of high-rise buildings.

[Problems to be solved by the invention] However, the scaffold described in Japanese Utility Model Publication No. 57-55873 cannot be installed unless an anchor is driven into the floor or beams of the building in advance. It is a scaffold that is difficult to use for building a building where it is inappropriate to expose the anchor to the floor due to the internal shape or usage. In addition, there are many existing buildings that do not have anchors on the floor, etc. Therefore, this scaffold cannot be used for exterior work and repair work of these buildings. .

The present invention simplifies and economically installs sash frames, makes tiles, makes exterior leaks such as caulks or repairs, and especially makes partial exterior works easy.
The purpose is to provide a scaffolding that is practical in the construction work of high-rise buildings.

[Means for Solving the Problems] In order to achieve such an object, the present invention constructs an assembly scaffold as follows.

That is, the mounting scaffold is formed by arranging the side frames 1 formed by assembling a pair of pipe members 2 in parallel so that the surfaces of the side frames face each other, and by mounting the scaffolding plate 12 between the side frames 1. A support member 3 is projectingly provided on an extension line of the surface of the side frame 1 on one of the pipe members 2 constituting the side frame 1, and a vertical portion 4 bent downward of the support member 3 is formed. It is assumed that the pressure pressing member 5 that is screwed in the horizontal direction is provided in the.

[Operation] Since the vertical portion 4 of the support member 3 projecting from the pipe material 2 constituting the assembly scaffold according to the present invention is provided with the pressing and clamping member 5 which is screwed in the horizontal direction, this support is provided. The member 3 is attached to the projecting portion 13 of the building, and the pressing and compressing member 5 is attached to the projecting portion 13 of the building.
When 5b is screwed so as to touch, the pressing frame 5b and the mounting plate 6 clamp the projecting part 13 of the building, and the side frame 1 is assembled to the projecting part 13 of the building.

The scaffolding plate 12 is made of a rectangular plate material. Hooks 12a are attached to the four corners of the scaffold plate.

Connect the connecting pipes 9 and 9 provided on the lower side frame 1a from the lower free ends of the pipe members 2 and 2 forming the upper side frame 1b.
And the holes 11 provided in the connecting pipes 9 and 9.
The lower side frame 1a and the upper side rod 1b are inserted by inserting a stopper such as a pin into the hole 11b from the opening of the hole 11a with the holes 11b and 11b provided in the pipe members 2 and 2 aligned with each other. Can be assembled together.

FIG. 2 shows the assembled scaffold according to the present invention assembled to the projecting portion 13 of the building. That is, after attaching the support member 3 assembled to the lower side frame 1a to the projecting portion 13 of the building and assembling the pair of side frames 1 to the projecting portion 13 of the building so that the surfaces of the side frames 1 face each other. ,
The hooks 12a, 12a of the scaffolding plate 12 are hooked on the support rods 7, 7 on the upper side of the lower side frames 1a, 1a so as to cross the lower side frames 1a, 1a, respectively, to thereby extend the projecting portion of the building.
The mounting scaffold according to the present invention is mounted on the 13.

A plurality of braces 14 are stretched between the side frames 1 and 1 in parallel with each other using the braces 10 and 10.

FIG. 3 shows an embodiment in which the assembly scaffolds according to the present invention are attached to the outer wall of the opening of the building in two rows, upper and lower.

FIG. 3 shows an embodiment in which the assembly scaffolds according to the present invention are attached to the outer wall of the opening of the building in two rows, upper and lower.

First, in the assembled scaffold according to this embodiment, the assembled scaffold according to the present invention is attached to the projecting portions 13, 13 of two consecutive floors of the building, respectively, and the connecting pipe 9 provided on the upper side of the assembled scaffold on the lower floor. , 9 are inserted through the lower free ends of the pipes 2, 2 which form the assembled scaffolds on the upper floor, and the two assembled scaffolds are integrated into two upper and lower scaffolds.

Next, a pipe support 14 extending from the floor to the ceiling of the building is provided in the building, and the pipe support 14 and the pipe member 2 constituting the scaffolding to be assembled are connected by a support rod 15 and a clamp 16.

When the shape of the overhanging portion 13 provided on the balcony or the like of the building on the outer wall side of the building is not flat, the pressing and pressing portion
Since the overhanging portion 13 cannot be sufficiently clamped and pinched by the 5a and the mounting plate 6, the assembly of the scaffold to the building becomes insufficient, so in such a case, between the overhanging portion 13 and the mounting plate 6. It is preferable to attach the scaffolding 17 and the scaffolding to the projecting portion 13 of the building.

Protective net 18 on the side of the assembly scaffold that is not in contact with the building
May be used in tension by locking one end of the protective net 18 to the bill of the building and tying the other end of the protective net 18 to an anchor buried in the ground.

[Advantage of the Invention] The assembled scaffold according to the present invention can be assembled to the outer wall of the building by attaching the support member 3 assembled to the side frame 1 constituting the assembled scaffold to the projecting portion 13 in the opening of the building. Therefore, it is not necessary to carry out the scaffolding framework from the ground, it is practical for the exterior construction of high-rise buildings, the scaffolding material can be reduced, and the labor for assembling and disassembling the scaffolding can be saved. It has practical utility in the exterior work and repair work of a building that is performed only in a part or several places of an unnecessary building.

Further, since the assembly scaffold according to the present invention can be assembled to the building only by screwing the pressing and pressing member 5, it is necessary to provide a special equipment such as an anchor to the building for assembling the scaffold. There is no. Therefore, the assembling scaffold according to the present invention can be generally used for exterior construction of a building regardless of whether the building has equipment for assembling scaffolding such as anchors, and the scaffold installation cost is low. It has the features to be completed.
