Abstract

(57) [Summary] [Purpose] Easy installation and removal of fall prevention shelves. [Structure] A slide guide 10 is provided on the lower surface of the scaffolding plate body 9. The slide guide 10 slidably supports the fall prevention shelf 11 on the lower surface of the scaffolding plate body 9.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a composite scaffolding board used at a construction site.

[0002]

[Prior Art]

 Generally, at a construction site, as shown in FIG. 6 or FIG. 7, a scaffold 2 is assembled outside a building 1, and a fall prevention shelf 3 is provided between the scaffold 2 and the building 1 to prevent parts from falling. ing.

In the case of FIG. 6, a bracket 4 is attached to the scaffold 2, and a wooden or steel plate 5 is laid on the bracket 4 to form a fall prevention shelf 3.

In the case of FIG. 7, single pipes 6 are projected from the scaffold 2 at predetermined intervals, and nets 7 are attached to these single pipes 6 to form a fall prevention shelf 3.

[0005]

[Problems to be solved by the device]

 However, such a method of forming the fall prevention shelf 3 has the following problems. (A) After the scaffolding 2 is assembled, after the outer wall body of the building 1 is completed, the fall prevention shelf 3 requires time and labor for material intake and construction. (B) Since it is necessary to remove the fall prevention shelf 3 at each step of dismantling the formwork, plastering work, and spraying work (tiling work), it takes time and effort. (C) It is difficult to recover because it requires binding wires and tools. (D) Regular inspection and maintenance are required.

An object of the present invention is to provide a composite scaffolding plate that can be easily attached / detached to / from a fall prevention shelf.

[0007]

[Means for Solving the Problems]

 To explain the configuration of the present invention to achieve the above object, the composite scaffolding plate according to the present invention is provided with a slide guide on the lower surface of the scaffolding plate body, and prevents falling onto the lower surface of the scaffolding plate body via the slide guide. The shelf is slidably supported.

[0008]

[Action]

 In such a composite scaffolding plate, since the scaffold body and the fall prevention shelf are integrated, the fall prevention shelf can be carried to the installation place together when constructing the scaffold, and it is possible to save labor. . Also, it is pulled out from the scaffold body when needed and stored under the scaffold body when it is no longer needed.

[0009]

【Example】

 1 to 3 show an embodiment of a composite scaffolding plate 8 according to the present invention. In this composite scaffolding plate 8, slide guides 10 are provided on the lower surfaces of both ends in the longitudinal direction of a scaffolding plate main body 9 made of steel, and a fall prevention shelf is provided on the lower surface of the scaffolding plate main body 9 via these slide guides 10. 11 is slidably supported.

The fall prevention shelf 11 has a structure in which an expanded metal 11b is stretched over a rectangular metal frame 11a. A stopper 12 is provided on the lower surface of the scaffolding body 9 to limit the length of pulling out the fall prevention shelf 11. Further, hooks 13 are provided at both ends in the longitudinal direction of the scaffold body 9.

Such a composite scaffolding plate 8 is installed by hooking a hook 13 on the pipe of the scaffolding 2. When the fall prevention shelf 3 is required, pull out the fall prevention shelf 3 from under the scaffolding plate body 9 as shown in the figure. When the fall prevention shelf 3 is no longer needed, it is stored under the scaffolding plate body 9. The metal frame 11a is not limited to the expanded metal, and various nets may be stretched.

[0012]

[Effect of the device]

 As described above, since the composite scaffolding plate according to the present invention has a structure in which the fall prevention shelf is slidably supported on the lower surface of the scaffolding plate body, the following effects can be obtained. (A) A fall prevention shelf can be installed at the same time as scaffolding assembly. (B) Various parts such as brackets for mounting the fall prevention shelf are not required. (C) The fall prevention shelf can be put in and taken out from under the scaffolding plate main body if necessary. (D) Assembling and disassembling the fall prevention shelf is unnecessary. (E) Make daily maintenance easier.
