Abstract

PURPOSE:To fix a shade cloth to a scaffold with high work efficiency by fitting and inserting a clip of a plate-like member having a U-shaped section and both side walls curved back to back with each other between adjacent scaffolding posts. CONSTITUTION:A clip 20 of a plate-like member having a U-shaped section consisting of a coupling section 24 and two side walls 23 and 23 extended substantially from tooth ends thereof in parallel with each other and both side walls 23 curved back to back with each other is provided. The clip 20 is made of an entirely elastic steel plate or it is made of hard plastic as a unit. The clop 20 is fitted and inserted between two adjacent scaffolding posts 12 and 12 from above of the shade cloth 21 stretched around along the inside of the external frame of the scaffold, and the shade cloth 21 is fixed to the scaffold.

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip, and more particularly to a clip for locking a shade cloth of a construction scaffold between adjacent scaffold supports.

0002

[Prior Art] In recent years, in order to prevent pieces of exterior wall materials from falling and causing damage to passersby and vehicles on the road at construction sites, wire mesh has been placed around scaffolding. There is. However, since such a wire mesh is inevitably made with a coarse mesh, it is impossible to prevent small pieces such as nails and gravel from falling. In order to prevent these small pieces from passing through the wire mesh, recently, shade cloth such as cold sand has been placed overlappingly on the inside of the wire mesh.

[0003] However, the known method of stretching shade cloth around a wire mesh requires extremely primitive and labor-intensive work such as tying it directly to the inner surface of the wire mesh or to scaffolding supports using strings or thin wires. It's here. Moreover, when such a method is adopted, it has been observed that the shade cloth often becomes scratched or torn, making it unable to withstand repeated reuse.

0004

SUMMARY OF THE INVENTION In order to avoid the above-mentioned undesirable situation and to simplify the installation work and shorten the work time, the present invention aims to install a shade cloth by inserting it into the gap between adjacent scaffolding supports. The purpose of the present invention is to provide a flexible clip that can be used to stop

[0005]

[Means for Solving the Problems] The clip according to the present invention has flexibility and is fitted between two adjacent scaffolding supports from above a shade cloth stretched along the inside of a scaffold outer frame in advance. A plate-like member with a U-shaped cross section, which is used to lock the shade cloth to a scaffold by inserting the shade cloth into the scaffold, and is composed of a connecting portion and two side wall portions extending substantially parallel to each other from both ends of the connecting portion. and further characterized in that said side walls are curved back-to-back to engage each of said scaffolding posts.

[0006] In a preferred embodiment of the present invention, the clip is entirely made of an elastic steel plate, and in a further embodiment, it is made of a single piece of hard plastic. Of course, it is also possible to manufacture a combination of these, in which the side wall connection portion is molded from hard plastic and the side wall portion is integrally molded from an elastic steel plate.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the clip according to the present invention will be described below with reference to the accompanying drawings. As seen in FIG. 1, any one scaffold 10 of the horizontally connected scaffold assembly is supported at each of its four corners by cylindrical supports 12, and is made up of a plurality of scaffold boards 11 formed in a layered manner. It is made from. In use, the scaffolds are arranged laterally next to each other, while each adjacent cylindrical column 12 is connected parallel and perpendicularly to each other by connecting members. The construction of such scaffolds and their attachment methods are extremely common. Furthermore, each of these scaffolds has a coarse screen or wire mesh 13 attached to its outer periphery to prevent debris from falling.

As seen in FIG. 2, a clip 20 according to the present invention has a substantially U-shaped structure for locking a nylon shade cloth 21 between a pair 22 of adjacent tubular scaffold posts 12. It has a cross section. As can be seen in FIGS. 2 and 3, this U-shaped cross-section clip 20 has a connecting portion 24 and two portions extending substantially parallel to each other from the connecting portion.
It consists of two side wall portions 23, 23, which are generally curved back to back and engage the opposing surfaces of the pair of struts 22, respectively. In this embodiment, the clip 20 is made of an elastic steel plate and has an integral structure.

[0009] When attaching the clip 20 to the scaffold support 12, it is preferable to first stretch the shade cloth 21 along the inside of the outer frame of the scaffold 10, and then temporarily fasten the shade cloth 21 at appropriate intervals. As a result, the shade cloth 21 covers the pair of columns 22 which extend parallel to each other, and is then completed by fitting the side wall portions 23, 23 into the gap between the pair of columns. By inserting the clips between the posts, the shade cloth 21 is pushed between the posts, and as a result, the shade cloth 21 is strongly tensioned between each of the scaffold posts. In addition, at this time, the outer surface of the side wall portion 23 which is curved as a whole is attached to the surface of the cylindrical scaffold support 12 with the shade cloth 21.
The shade cloth is thus securely locked between the adjacent posts.

[0010] Except in special cases, this clip 20 has a length that covers the entire width of the shade cloth 21.
As a result, the entirety of the shade cloth 21, which is laterally connected to each other, is stretched tightly and seamlessly inside the screen or wire mesh 13 described above.

The above-mentioned clip is shown in FIGS. 2 and 3.
As can be seen from the figure, for convenience, we have shown an example in which the entire body is made of one steel plate, but there are also other examples, such as those made integrally of flexible hard plastic, or the connecting part 2.
4 may be made of hard plastic and the side wall portion 23 may be made of an elastic thin steel plate, and it goes without saying that these also fall within the scope of the present invention.

0012

[Effects of the Invention] As described above, the clip according to the present invention can lock the shade cloth stretched around the inner circumference of the scaffold to the scaffold with a single touch, and therefore can be attached directly to the wire mesh or to the scaffolding support with a string or thin Since time-consuming work such as tying with wire etc. is avoided, work efficiency including removal is greatly improved, and since it is possible to avoid creating scratch holes in the shade cloth, it is possible to repeatedly reuse it. Excellent in this respect. Furthermore, the advantage that the structure is extremely simple and therefore easy to manufacture cannot be overlooked.
