DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shroud surrounding a construction site.

[0002]

2. Description of the Related Art In general, a surrounding plate surrounding a construction site is formed by bending both side edges of a vertically long plate made of a steel plate, aluminum, an alloy thereof, or a synthetic resin material into a U-shape in plan view. It is. And such a surrounding plate surrounds the periphery of the construction site by arranging the U-shaped edges of the surrounding plate adjacent to the horizontal rail portion of the fixed frame framed around the construction site in a state where they are in contact with each other. After engaging the hook portion at the tip with the horizontal frame member of the fixed frame with the "U" shaped metal fitting having the hook at the distal end portion straddling the horizontal frame member of the fixed frame. The edge of the shroud, which is engaged with the hook at the tip end by bolts or the like, is drawn toward the horizontal frame member side of the fixed frame and fixed to surround the construction site with the shroud.

[0003] However, in the above-mentioned conventional enclosing plate which is connected in a state where two side edges bent in a U-shape in plan view are connected to each other, a gap is easily formed between the two side edges. was there. In addition, a special “U” created separately from the shroud is attached to the side of the fixed frame.
In addition to being expensive to fix with the shape fittings, if the "U" shape fittings are lost or the number is insufficient, it becomes impossible to mount or can only be mounted in an unstable state. there were.

To cope with such a problem, for example, as shown in Japanese Patent No. 2640711, both side edges of an enclosing plate are bent into a crank shape that can be fitted to each other to form a fitting portion. A connector in which a connector insertion hole is formed in the fitting portion has been proposed. In such a surrounding plate, when the wires are arranged side by side, a wire or the like is inserted through a connector insertion hole of an adjacent surrounding plate, and the inserted wire or the like is wound around a horizontal rail portion of a fixed frame to fix the surrounding plate. It is.

[0005]

However, in the case of the shroud described in the above-mentioned publication, the connector insertion hole is formed in a fitting portion which is bent in a crank shape, so that it is located on the construction site side (the shroud of the shroud). It is difficult for workers who stand and operate this connector to see this connector insertion hole, and in reality, it is necessary to check the connector insertion hole in the state of holding a hand and insert the wire,
Not only is it troublesome and takes a lot of time,
There has been a problem that there is a high risk that a hand may be damaged by a sharp edge portion cut off by shearing or pressing during hand gesture.

Further, when the ground portion on which the shrouds are juxtaposed is inclined, the through holes of the joints formed in the adjacent shrouds are displaced from each other and are covered with each other so that the through holes of the joints can be inserted. There was also a problem that the holes could not be used. In view of the above, the present invention has been proposed in view of the above problems. Even when a shroud is installed and used on a slope, the connector insertion hole can be easily visually recognized, and the connector can be easily and safely inserted. It is an object of the present invention to provide a construction site shroud capable of fixing a shroud.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, a construction site shroud according to the present invention, when laid at both end portions of a vertically long plate material, has the edges of adjacent shrouds that are adjacent to each other. A construction site enclosure in which a crank-shaped engagement connection portion is formed in a plan view so as to fit, and the crank-shaped engagement connection portion is brought into contact with each other so that an enclosure plate is continuously provided around the construction site. In the plate, the distal end portion of the crank-shaped fitting connection portion is bent toward the center portion so as to be parallel to the enclosing plate, and a connector insertion hole is formed in the parallel bent portion. .

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a construction site shroud according to the present invention. FIG. 1 is a plan view showing a part of an enclosing plate installed so as to surround the periphery of a construction site. In the figure, reference numeral 1 indicates a number of enclosing enclosing plates.

A plurality of the surrounding plates 1 are arranged in a state where their side edges abut against a horizontal frame member 3 of a fixed frame 2 framed by a pipe or the like so as to surround the periphery of the construction site. It is fixed at 4.

Each of the enclosing plates 1 is formed into a colorful shape by forming a synthetic resin layer 6 on the surface of a plate 5 made of a substantially rectangular thin steel plate, aluminum, an alloy thereof, or a synthetic resin material by, for example, an adhesive or baking. Finished.
As shown in FIG. 2, both side edges of the enclosing plate 1 are first bent in a crank shape toward the back surface 1 a side in a plan view, and then bent inward from the end thereof so as to be parallel to the back surface of the enclosing plate 1. The parallel bent portion 7 is formed.

Next, the edge portion 8 of the parallel bent portion 7 is further bent in a direction approaching the back surface 1a, and the crank-shaped portions of the both side edges are formed into a fitting connection portion 9 which can be fitted to each other. Have been.

A connecting part insertion hole 1 for inserting the connecting part 4 is formed in the parallel bent part 7 on both side edges of the surrounding plate 1.
0 is drilled. This connecting tool insertion hole 10 is
A long hole is previously punched out at equal intervals by a press at a position to be the parallel bent portion 7, and the edge portion 8, the parallel bent portion 7, and the crank-shaped fitting connection portion 9 are formed by being bent in order. After the enclosure plate 1 is completed, the connector insertion hole 10 can be formed with a punch such as a drill.

Further, the shape of the connector insertion hole 10 is not limited to a long hole, but may be various shapes such as a square, a triangle, a circle, and an ellipse.

A procedure for surrounding the construction site using the construction site enclosure plate 1 configured as described above will be described below. First, a fixing frame 2 for fixing the surrounding plate 1 around the construction site is assembled. Next, the enclosing plate 1 is set up along the horizontal rail portion 3 of the fixed frame 2 in a state where the fitting connection portions 9 on the side edges thereof abut against each other.

Thereafter, as shown in FIG. 3, the worker attaches the connecting member 4 made of a wire or the like from the back side of the enclosing plate 1 to the biparallel bent portion 7 on the distal end side of each fitting connection portion 9 to be abutted. When the connection tool insertion hole 10 and the horizontal bar portion 3 of the fixed frame 2 are entangled and the three members are securely fixed, the shroud plate 1 is fixed to the horizontal bar portion 3 of the fixed frame 2. is there.

When the construction site surrounded by the surrounding plate 1 has undulations, as shown in FIG. 4, the horizontal bar portion 3 of the fixed frame 2 has a shape inclined along the undulations of the construction site. Are vertically stepped, but in such a case as well, the connecting member 4 made of a wire or the like is connected to the cross bar portion 3 and the When the three members are securely fixed by being hooked to the adjacent connector insertion holes 10 and 10, the shroud 1
It is fixed securely.

In this case, the connector insertion hole 10 can be added to the parallel bent portion 7 on site by a drill or the like.

[0018]

As described above, the shroud for a construction site according to the present invention forms a fitting connection by bending both end edges of a vertically long plate material into a crank shape in plan view. The distal end of the fitting connection portion is bent toward the center so as to be parallel to the surrounding plate, and a connector insertion hole is formed in the parallel bent portion.

Therefore, in the shroud of the present invention, since the connector insertion hole is always exposed to the parallel bent portion parallel to the back of the shroud, the operation is performed while standing on the construction site side (the back of the shroud). The operator can confirm the position of the connector insertion hole at a glance.

[0020] Thus, there is no danger that the hand will be damaged by the sharp edge portion when the connecting tool insertion hole is confirmed in the state of holding the hand as in the prior art. There is an advantage that the surrounding plate can be fixed by inserting a connecting tool such as the above into the connecting tool insertion hole.

Further, even when the ground portion on which the shrouds are juxtaposed is inclined, the connector insertion holes formed in the adjacent shrouds as in the related art do not shift and are not covered with each other. In addition, the shroud plate can be easily installed even on an uneven construction site, and there is an advantage that the degree of freedom of juxtaposition of the shroud plate is increased.
