Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used to fix a sheet to a pipe-shaped member of a scaffold temporarily installed at a construction or civil engineering work site. In particular, it relates to a fitting that passes through the seat eyelet.

[Conventional technology]

Scaffolding temporarily erected at construction and civil engineering sites has traditionally used thin logs and fixed-length pipes as members, but recently scaffolds of fixed dimensions and sizes have been used to facilitate the installation and removal of temporary works. We are trying to streamline on-site construction by using system scaffolding that has been processed into a shape.

With conventional scaffolding that uses logs and other materials,
Since the installation spacing of the members is set independently of the dimensions of the sheets, the sheets covering this scaffolding are made by overlapping the eyelets of the two sheets at one point at the ends of the mutually adjacent sheets, and then using wires. Methods such as tying them up were used.

However, in system scaffolding, in order to use a reasonable number of sheets and have a good appearance, the joints of adjacent sheets are dimensioned so that there are no gaps at the ends. ,
The eyelets of the two sheets do not overlap. What's more, the joints of the sheets are now aligned with the scaffolding pipes.

[Problem that the invention attempts to solve]

For this reason, conventional attachments cannot be used, so wires, ropes, etc. are used to connect them, but these are time-consuming and difficult to secure to scaffolding members.
The problem was that the sheet could shift or come off due to strong winds.

An object of the present invention is to solve this drawback and provide a fixture for attaching a scaffold pipe to a sheet, which has good workability and prevents the sheet from loosening when attaching the sheet to a system scaffold.

[Means for solving problems]

The present invention has a structure of a fitting for attaching a sheet covering architectural scaffolding to the scaffolding pipe at the junction of two sheets, which has an approximately arcuate shape and an eyelet provided on each of the two sheets. Two legs are formed whose inner sides are curved against the outer surface of the scaffolding pipe, and jaws are formed at the inner bases of the two legs, and a jaw is formed near the tips of the two legs. The present invention is characterized in that two holes are respectively inserted through which wires are inserted, which are wound around the scaffolding pipe and tightly fastens the fixture to the scaffolding pipe.

The legs are made of a soft plastic material, and the wire is made of iron wire covered with a plastic covering, and when the wire is tied to the scaffolding pipe, the jaws installed at the inner bases of the two legs are It is preferable that the structure is such that the tip thereof deforms into a shape that is stably supported by contacting the outer surface of the scaffolding pipe.

[Effect]

The two legs of the fixture are inserted through two opposing eyelets of the two sheets, with a portion of each leg holding the inner edge of the eyelet. Insert wires into the two holes provided near the tips of the legs of the fixture and tighten them to the scaffolding pipe.

As a result, the eyelets of the two sheets are held at a constant interval by the legs of the fixture, so the seat mounting pitch remains constant and does not change even in strong winds. The legs of the fixture are made of a flexible plastic material so that they can be bent towards the scaffolding pipe and stably supported on the outer surface of the pipe. If the wire is covered with plastic, the frictional force of contact between the wire and the scaffolding pipe will be further increased, and the possibility of the sheet slipping down will be greatly reduced.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of this embodiment installed on a scaffolding pipe and a sheet, and FIG. 2 is a front view thereof.

1 and 2, the fixture 1 of the present invention has two legs 1A, two holes 1B are provided in the tip 1C of the legs 1A, and two holes 1B are provided in the inner base of the legs 1A. The jaw 1D is formed. The legs 1A are then inserted into the eyelets 3A and 3B of the sheets 2A and 2B, respectively, and attached to the scaffolding pipe 4.

Here, the feature of the present invention is that the fixture 1 has a substantially arcuate shape, and the fixture 1 has two
At the junction of the sheets 2A and 2B, the two legs 1A are inserted through the eyelets 3A and 3B provided on each sheet, and are curved against the outer surface of the scaffolding pipe 4. Two holes 1B are formed through the distal ends 1C of the legs, and jaws 1D are provided at the inner bases of the legs 1A.

Furthermore, the leg tips 1C of the fixture 1 are made of a soft plastic material, the wires are made of iron wire covered with a plastic covering, and the two legs 1A are made of wires that are attached to the scaffolding pipe 4. When tied up, the jaws 1D and inner tips of the legs abut against the outer surface of the scaffolding pipe, deforming into a shape that is stably supported.

A method of attaching the fixture of the present invention will be explained with reference to FIG. In FIG. 3, for clarity, the wire 5, which has a structure in which the iron wire 5B is covered with a plastic coating 5A, is indicated by a chain line with a black circle.

As shown in FIG. 1, after attaching the fixture 1 to the eyelet of the seat, the wire 5 is crossed as shown by the arrow X in FIG. is deformed in the direction of arrow Y, resulting in the state shown by the broken line. Therefore, the jaw 1D and the tip 1C of the leg 1A are strongly abutted against the outer surface of the scaffolding pipe 4. After the wire 5 sufficiently draws the fixture 1 to the scaffolding pipe 4, it is twisted and tightened.

When the leg 1A of the fixture is inserted into the eyelet, the leg 1A is bent back and its tip part holds a part of the inner edge of the eyelet, so the distance between the eyelets is unified to the pitch of the leg of the fixture. .

When the wire is tightened, the legs of the fixture will come into strong contact with the outer surface of the scaffolding pipe, and since the wire has a plastic coating, the frictional force will be large.
When the sheet is attached to the scaffolding pipe, the contact force becomes even stronger.

FIG. 4 is a front view of another embodiment of the present invention, which is an example of a fixture 1' having a large contact area in order to increase the contact force between the sheet and the scaffolding pipe.

FIG. 5 is a perspective view of the fixture of the present invention sold as a component.

[Effect of idea]

According to the present invention, the installation of the scaffolding pipe and the sheet is easy because the sheets are held together by simply inserting the fixture into the eyelet, and there is no need to wrap the fixture itself around the scaffolding pipe to fix it.
The installed appearance of the sheet is good, and construction can be carried out with little risk of loosening even in strong winds. Furthermore, since the seat eyelets are not held in place by thin wires like conventional wires, there is an effect that the eyelets are less likely to be damaged.
