Description

[Detailed description of the invention] Industrial field of application This invention is a temporary structure such as scaffolding at a building construction site, etc., which is erected on the outside surface so as to surround the construction site, and bolts or other bolts are removed from the construction site. This invention relates to a construction sheet used to prevent construction materials from falling over the scaffolding surface and to ensure the safety of passersby.

PRIOR TECHNOLOGY This type of construction sheet is rectangular with a certain width and length, and eyelet metal fittings are attached to its periphery at equal intervals as shown in Figure 2. The required number of sheets are connected vertically and horizontally using strings, wire ropes, etc. using the eyelet hardware described above.

Problems to be Solved by the Invention In the above-mentioned conventional construction sheet, the upper sheet and the lower sheet are strongly tied together using strings, wire ropes, etc. at the positions of the eyelet metal fittings A, but the horizontal eyelet metal fittings are , A is likely to form a gap, and for this reason, when construction materials fall inside the construction site, there is a risk that they will fly out through the gap A.

In addition, by providing a protective curtain inside the upper sheet C to cover the above-mentioned gap H as shown in Fig. 3,
Although the above problem has been solved to some extent, construction materials include sharp objects, and if such sharp construction materials fall while pressing the upper seat plate outward, If it hits the joint with the protective screen, there is a risk of damaging the joint.

In particular, recently construction sheets have been used on construction sites as long-term leases or rentals, or have been repurposed repeatedly, so further improvements in safety and durability are desired.

The present invention attempts to solve the above problems.

Means to Solve the Problem This idea is to make a rectangle with a certain width and length, attach eyelet metal fittings at equal intervals around the periphery, and attach the required number of sheets to the eyelet metal fittings according to the scale of the construction site. In construction sheets that are connected vertically and horizontally using strings or wires to surround the construction site, the vertical dimension is slightly longer than the standard dimension to form a covering section at the bottom that covers the seams of the sheet. It consists of a sheet main body and a small sheet connecting piece that has the same width as the seat main body but has a short vertical dimension and has metal eyelets attached at equal intervals to its lower end to form a seat connecting part. The sheet connecting portion at the lower end of the sheet connecting piece is sewn to the lower outer surface side of the main body at a position above the lower end of the sheet main body and covered by the covering portion of the sheet main body, and the sheet connecting portion is This is connected to the upper end of the next seat body located below.

Function The construction sheet of this invention has the above-mentioned structure, so that there is no stepped part on the inside facing the construction site that is harmful to falling construction materials, and sharp construction materials do not touch the sheet. Even if it falls while pushing outward,
It can be slid down smoothly without resistance, just like sliding down a slide. Embodiment FIG. 1 is a cross-sectional view of main parts showing an embodiment of the construction sheet according to the present invention, in which 1 is a seat body that becomes, for example, an upper seat, 2 is a small piece for connecting the seats, and 3 is, for example, a lower seat. In other seat bodies, the other end (for example, the lower end) of this seat body 3 has a structure similar to that of the present invention.

The sheet body 1 is made of flame-retardant fibers with a predetermined strength or flame-retardant treated fibers, or synthetic fibers that have been subjected to flame-retardant treatment. It is cut into a rectangular shape with predetermined dimensions, and the periphery is folded back and sewn to be reinforced, and at that time, the periphery is reinforced by wrapping the synthetic resin sewing rope 4 as a core material together with the sewing tape 5 or the cloth, In addition, eyelet metal fittings 6 are attached to the edges of each side at equal intervals, and the sheet body 1 has:
The covering portion 1a of the sheet connecting portion 2a of the sheet connecting piece 2 is formed to extend continuously. This extended length is 150mm longer than the standard for conventional sheets.

The sheet connecting piece 2 is made of the same material as the sheet main body 1 (in some cases, a different material may be used), and has a sheet connecting part 2a at one end, and the other end 2b is formed on the outer surface side A of the sheet main body 1. is sewn in place. The width of this sheet connecting piece 2 is the same as that of the seat main body 1, and its length is determined by the fixing margin of the other end 2b fixed to the seat main body 1, the folded reinforcement part of the seat connecting part 2a, and the eyelet hardware 6. The installation cost should be minimal. For example, the length of the sheet connecting piece 2 is 100 mm, and it is sewn to the outer surface of the sheet body 1 at a distance of 250 mm from the sheet connecting portion 2a at one end of the sheet body 1 to the other end.

The sheet connecting portion 2a is sewn together with the sewing tape 5 using the sewing rope 4 as a core material so that the end portions of the sheet connecting pieces 2 are folded back to double wrap around the core material.

Further, the other end 2b of the sheet connecting piece 2 is folded back so as to wrap around the sewing tape 5, and in this state is attached to the outer surface side A of the sheet body 1 at a plurality of locations. The meeting position of the other end 2b is a position where the sheet connecting portion 2a is covered with the covering portion 1a.

A similar sheet connecting portion 3a is formed at the end of the other seat body 3, and both sheet connecting portions 2
a, 3a are tightly connected with strings, wires, etc. at the positions of the eyelet metal fittings 6, 6.

In the above embodiment, the sheet body 1 has a net shape, but is not limited thereto.

Effects of the invention According to this invention, there is no stepped part on the inside of the construction site that is harmful to falling construction materials, and even if sharp construction materials fall while being pressed against the outside of the sheet, It smoothly passes through the sheet connection part without resistance, just like sliding on a slide, preventing damage to the sheet, and also ensures safety by preventing the construction materials mentioned above from breaking through the sheet and flying out. It can improve the durability of the sheet and increase the durability of the sheet.
This method has the advantage that it can be implemented easily and inexpensively, since it is only necessary to slightly extend the standard dimensions of the conventional sheet and to attach a small piece for connecting the sheets to the outer surface of the sheet.
