Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet for construction work used for a construction site such as a new construction, demolition, and renovation of a building or a painting site, a sheet for preventing paint scattering, or a sheet for displaying an advertisement used for outdoor advertisement. And a sheet to be stretched by such a sheet tensioning tool.

[0002]

At a construction site, a scaffold is provided around a building, and a sheet is stretched to further surround the scaffold. Conventionally, the unit sheet and the unit sheet or the sheet and the scaffold when tensioning the sheet are
A rope or a wire is successively passed through eyelet holes provided in each sheet to be connected.

By the way, it is very poor in workability to stretch the sheet through the eyelet hole by thus using a rope.
I spend a lot of time. In addition, such a connection by a rope requires preparing a unit sheet having eyelets formed therein, and the unit sheet itself has to be expensive and is not so satisfactory. Such a problem also occurs in a sheet stretched at a painting site, a sheet for displaying an advertisement used in an outdoor advertisement, and the like.

The present invention has been made in view of the above points, and an object of the present invention is to provide a combination of sheet tensioning tools capable of extremely easily performing sheet tensioning and tensioning using the combination. To provide the sheets to be done.

[0005]

According to the present invention, the object is a combination of a first sheet tensioning tool and a second sheet tensioning tool, the first sheet tensioning tool comprising: An edge of a sheet which has a first hole for slidably receiving an enlarged portion formed at one outermost edge extending in the lateral direction of the uppermost sheet or the lowermost sheet and which is continuously provided to the enlarged portion of the sheet. A semi-cylindrical portion that has a first slit formed continuously with the first hole so that the portion passes, and a semi-cylindrical portion that extends in the lateral direction and that extends along the longitudinal direction of the semi-cylindrical portion and A mounting plate portion integrally formed with the semi-cylindrical portion facing the slit of the mounting plate portion, the mounting plate portion having a long hole extending along the longitudinal direction of the semi-cylindrical portion. The second sheet tensioning tool is formed of two integrally formed laterally long semi-cylindrical parts. One semi-cylindrical portion of the second sheet tensioning tool slidably receives the enlarged portion formed at the other outermost edge of the uppermost or lowermost sheet extending in the lateral direction. While having a second hole, a second hole formed continuously to the second hole so that the edge of the sheet continuously connected to the enlarged portion formed at the other outermost edge of the sheet passes. It has a slit, the other semi-cylindrical portion of the second sheet tensioning tool is formed to face the second slit, and is adjacent to the uppermost or lowermost sheet in the vertical direction. A third hole for slidably receiving an enlarged portion formed at one outermost edge of the other sheet which is to be continuously connected with the other sheet, and formed at one outermost edge of the other sheet. So that the edge of the other sheet connected to the enlarging part that passed through,
A third slit continuous with the third hole and formed to face the second slit, and the second sheet tensioning tool further includes the second sheet tensioning device. A long hole through which a cord-like body that connects the tool to the frame can be inserted is extended along the longitudinal direction of the two integrally formed semi-cylindrical portions, and the two holes are provided between the second hole and the third hole. This is achieved by a combination of the first and second sheet tensioning tools that are provided so as to penetrate the connecting portion of the semi-cylindrical portion.

In addition, according to the invention, said object is a sheet to be stretched by said combination,
Achieved by a sheet having an ampulla at least at the opposite outermost edges.

The sheet tensioning tool of the present invention is made of wood,
It may be made of metal or synthetic resin, but from the viewpoint of mechanical strength and lightness, it is preferably made of hard plastic or aluminum, and most preferably aluminum.
Further, in the sheet tensioning tool of the present invention, in order to reduce the weight, a hollow portion may be formed as long as mechanical strength permits. On the other hand, the length of the sheet tensioning tool of the present invention may correspond to the length of the long side and the short side edge of the applied sheet, but instead of this, the long side and the short side of the applied sheet. The length may be sufficiently shorter than the length of the sheet, and a plurality of such short sheet tensioning tools may be applied to adjacent edges of both sheets to stretch the sheet. Especially when the length of the edge of the sheet is several meters or more, if the required number of sheet tensioning tools of about 1 meter long are used to connect the adjacent edges of both sheets,
Seat tension work can be easily performed.

The sheet in the present invention may be a general sheet obtained by extrusion molding such as a nylon sheet or a vinyl sheet, or a cloth or non-woven fabric made of natural fiber or chemical fiber or a combination thereof. Sheet may be used. Further, the sheet in the present invention does not have to be completely clogged, and may be a mesh sheet called a so-called net.

In the present invention, the enormous portion of the sheet includes:
The edge of the sheet itself may be swelled by integral formation, or may be obtained by rolling the edge of the sheet itself.Furthermore, the edge of the sheet may be folded back. The sewn portion may be an enlarged portion formed by inserting a rope into a loop formed therein. The enlarging portion of the sheet in the present invention does not have to be formed at all the outermost edges of the sheet, and may be formed at least at the opposite outermost edges of the sheet in relation to the sheet tensioning tool to be used. . Further, it is not necessary to have the enlarged portion continuously over at least the entire length of the opposing most edge portion, and it is necessary to have the enlarged portion discretely at least at the opposing most edge portion, in other words, a discretely enlarged portion. You can. The cross-sectional shape of the enlarged portion may be circular, triangular or quadrangular, or even more polygonal.

The hole formed in the sheet tensioning tool that slidably receives the enlarged portion may be a through hole that opens to the outside at both ends, but at least one end is the outside for inserting the enlarged portion. The hole may be a hole having a bottom, and the other end may be closed. Regarding the cross-sectional shape of the hole, in relation to the shape of the enlarged part, even if it is circular,
It may be a triangle or a quadrangle, or may be a polygon having more than that.

The width of the slit formed in the sheet tensioning tool should be such that the enlarged portion of the sheet does not come out through this slit. If it is too narrow, the flexibility of the sheet is lost and the sheet tensioning work is difficult. In addition, the edge of the sheet may be damaged. In order to prevent damage to the edge of the sheet, it is preferable that the portion of the sheet tensioning tool that defines the slit is formed smoothly.

There is only one elongated hole through which the cord-like body for connecting the second sheet tensioning tool to the frame can be inserted, as long as the sheet tensioning tool can be connected to the frame. In order to connect the long sheet tensioning tool to the framework without causing a tilt, without decreasing the height, it is preferable to provide a plurality of the sheet tensioning tools discretely in the longitudinal direction. A rope, a wire, or a belt with a buckle can be exemplified as the string-shaped body inserted into the long hole, but it is needless to say that it may be another one.

The seat assembly assembled using the sheet tensioning tool of the present invention is not limited to being applied to construction work, but may be applied to, for example, a painting site or an advertisement display.

In the combination of the present invention, a wire or rope is inserted through the long hole of the attachment plate portion of the first sheet tensioning tool, and the wire or rope is wound around the lateral member of the scaffold,
The first sheet tensioning tool is fixed to the scaffold, and the enlarged portion formed in the first hole of the semicylindrical portion of the first sheet tensioning tool, for example, at the outermost edge of the uppermost sheet. Insert the second sheet tensioning tool into the second hole of one of the semi-cylindrical parts, and insert the enlarged portion formed at the lowermost outer edge of the uppermost sheet into the second sheet. Into the third hole of the other semi-cylindrical part of the tensioning tool, insert the enlarging part formed at the uppermost edge part of the uppermost sheet of the next stage, which is connected to the uppermost sheet, and perform this work. Further, the seat assembly can be obtained by repeating the operation with respect to the other prepared sheet tensioning tools and sheets and the lowermost sheet. Then, for example, if the seats are stretched from the bottom to the top in line with the progress of the construction work of a high-rise building and the seat assembly is raised one after another in correspondence with the height of the building under construction work, (2) Connect the string-like body that has passed through the long hole of the sheet tensioning tool to the frame, temporarily fix the uppermost sheet tensioning tool to the frame during the construction work, and after this temporary fixing, seat on the upper part. When tensioning the sheet, the temporary fixing is released and a new sheet is applied to the sheet tensioning tool.
