BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in order to suppress adverse effects on the outside due to noise and dust generated during work at a construction site, provides sheets to a wall plate such as a temporary enclosure universal plate surrounding the site. The present invention relates to a fixture for tensioning.

[0002]

2. Description of the Related Art In recent years, the importance of work and the safety of the surroundings at a construction site, especially in urban areas, it is obligatory by law to enclose a building with a temporary enclosure. The temporary enclosure is made by connecting rectangular metal panels, which are generally called universal plates, but it is easy to get stains and scratches due to repeated use with a single color, and when viewed from the outside it kills the surrounding landscape and damages the surrounding landscape. It imposes a mental burden on residents and passers-by. Therefore, there are some places that try to eliminate disproportion with the surroundings by designing a painting on the surface or designing the completed appearance of the building after enclosing the surroundings with a temporary enclosure universal plate, but relatively At the construction site with a short installation period, it is the current situation that it is rarely done because of the increase in costs. Therefore, a dedicated curing sheet for decoration is used so that it can be used in the field where the construction period is relatively short.
Techniques for installing and tensioning a tortoise (for example, JP-A-3-221667 and JP-A-4-92056) have been disclosed.

[0003]

However, the curing sheet used in these construction methods is stretched on the pipe of the temporary scaffold by passing a string or the like in the eyelet formed around the sheet as in the conventional case. Since it is fixed to the scaffolding, the work process does not increase, but when attaching it to the temporary enclosure, use an adhesive tape etc. as a separate member,
Another problem is that it requires application of an adhesive to the surface and takes a long construction time. Sheets having an adhesive treatment on the back surface have been proposed in terms of easy attachment, but the cost increase cannot be denied.

The present invention has been made as a result of intensive studies in view of the above problems. The purpose of the present invention is to easily attach and detach sheets in which sheets are stretched on a wall plate such as a temporary enclosure universal plate. It was an attempt to solve the problem with a fixture so that it could be reused.

DISCLOSURE OF THE INVENTION The present invention is a sheet-like member made of metal or other material, which is bent so as to have a substantially U-shaped cross-sectional shape, and a sheet-end inserting member. A wall plate sheave characterized in that it comprises an attachment fixing portion 1 elongated in the bending direction of the portion, and a slit hole 3 having a predetermined length is formed in the attachment fixing portion in a direction perpendicular to the bending portion 5. It is a fixing tool.

The universal plate used for the temporary enclosure is formed by connecting rectangular metal panels. As a connecting method, a through hole is provided in a portion where the universal plates are overlapped with each other, a bolt is inserted, and the nut is fixed with a nut. The present invention is a jig for tensioning sheets by using bolts and nuts fixed to the through holes necessary for connection.

As a basic structure, it is composed of two members, that is, a seat end insertion portion 2 and a mounting and fixing portion 1. See
The toe end insertion portion 2 is for locking the edges of the sheets, and has a substantially U-shaped cross section with an opening,
Also included are those having a substantially circular shape with a large curvature and those having a cross-sectional shape with a bottom portion wider than the opening portion. The attachment fixing portion 1 is for inserting a bolt into the slit hole 3 formed and tightening it with a nut to fix it to the wall plate. The two members can be formed as separate members and joined to each other, but they can also be formed by bending a single plate-shaped object or can be integrally molded of synthetic resin.

At this time, it is necessary that the edge of the sheet to which the sheet is locked has rigidity, and a thick edge is used for the conventional edge rope, or the edge edge is folded several times. It is configured by joining in a bag shape and inserting a molded product.

[0009]

The sheet sheet seat fixing device of the present invention is constructed such that the sheets are stretched on the wall sheet by utilizing the members conventionally used for constructing the universal plate. The structure can be stretched without any special treatment, and can be used repeatedly by using bolts and nuts.

EXAMPLES The structure of the present invention will be described below with reference to examples.

The vicinity of the center of the steel plate is bent into a substantially U shape to form a seat end insertion portion 2, and a long steel plate extending in the bending direction of the seat end insertion portion is used as a mounting fixing portion 1 and the tip of the mounting fixing portion. The seat end insertion portion 2 was attached to the sheet by welding. At this time, the seat end insertion portion 2 is mounted so that the opening is located above and the mounting fixing portion 1
A slit fixing hole 3 is formed in a vertical direction with respect to the bent portion 5 to form a sheet plate sheet fixing tool of the first embodiment, the opening is attached at a lower position, and the slit hole 3 is similarly formed. Is used as a sheet plate seat fixing tool of the second embodiment, and FIG. 1 (a) is a perspective view of the first embodiment, and FIG. 1 (b) is a perspective view of the second embodiment.

When the sheet 6 is stretched on the wall plate using the sheet plate sheet fixing device of the first and second examples, the first example is attached to the sheet 3 at three positions on the upper surface of the sheet. As shown in FIGS. 2 (a) and 2 (b), sectional views are shown in which the fixtures of Example 2 are stretched at three locations on the lower surface of the toe.

When the sheets are stretched, the upper and lower edges of the sheet 6 are folded back and joined in a bag shape, and a plate-shaped molded product 7 is inserted in the space. The sheet fixing member on the upper surface of the sheet has the sheet end insertion portion 2 opened upward, and the sheet end edge in which the plate-shaped molded product 7 is inserted is inserted into the opening from the upper side to insert the sheet. Even if the toe 6 is pulled downward, it will not come off unless it is loosened. In order to prevent the seat 6 from slackening, the vertical slit holes 3 formed in the mounting and fixing portion 1 are used. The upper surface sheet fixing tool is downward and the lower surface sheet fixing tool is upward. The sheet 6 can be strengthened by temporarily fixing the sheet 6 and inserting the sheet edge into the sheet end insertion portion 2 and moving them in the opposite directions.

The third embodiment is a modification of the seat end insertion portion 2. The cross-sectional shape of the sheet end insertion portion 2 is curved in a substantially circular shape, and the molded product 7 to be inserted into the space portion of the sheet edge is cylindrical. Example 4 is also a modified example, in which the sheet end insertion portion 2 is bent into a generally trapezoidal cross section with a narrow opening side, and a molded article 7 to be inserted into the sheet edge has a similar cross section. Is. Example 5 is a modified example of the slit hole 3 in which the sheet end insertion portion 2 is formed by bending a plate-like object having a shape close to a narrow rod. FIG. 3 is a sectional view showing a state in which Example 3 is attached to the upper surface of the sheet, FIG. 4 is a sectional view showing a state in which Example 4 is attached to the upper surface of the sheet, and FIG. The figure is shown in FIG.

Here, it is necessary to slide the seat edge from the side surface into the seat end insertion portion 2 of the seat fixing device of the third and fourth embodiments. Toe end insertion part 2
