etc. were provided.

(Problem that the invention aims to solve) However, the former type is used for partitions and blindfolds in homes and businesses, and the latter type is used as gates in homes, etc., and both are used at construction sites and other places. Not only is it troublesome to attach and detach the entrances of trucks, etc. to temporary enclosure pipes, etc., but it is also impossible to rotate the screens and gates that have been reduced when opening them to the inside of the construction site, etc., making it difficult to close the frontage of the entrances and exits. It has the disadvantage of being narrow, making it unsuitable for entrances and exits for construction sites, trucks, etc. Moreover, the expansion and contraction of the hinge fittings, support arms, horizontal pantograph bodies, vertical pantograph bodies, etc. is not smooth and lacks reliability, and furthermore, the strength of the hinge fittings, support arms, horizontal pantograph bodies, vertical pantograph bodies, etc. It was weak and extremely inconvenient during typhoons.

This idea was devised to solve the above-mentioned problems, and it not only makes it extremely easy to attach and detach the temporary fence pipes at the entrances and exits of construction sites and trucks, etc. This makes it ideal for entrances and exits at construction sites and trucks, etc. Moreover, it can be opened and closed very smoothly and quickly, and the frontage of the entrance and exit can be used widely.Furthermore, the expansion and contraction action of the expansion and contraction member of the gate body is extremely smooth. Moreover, the present invention provides a temporary gate for construction sites, etc., which is reliable and extremely convenient even during typhoons.

(Means for solving the problem) In order to achieve the above-mentioned purpose, this invention has a suitable number of pipes on one side for fixing to temporary fence pipes, etc. at entrances and exits for construction sites, trucks, etc. Hanging columns arranged alternately in the left and right direction between fixed columns with hinge clamps attached vertically at appropriate intervals and rotatable rearward, and movable columns with casters attached to the lower ends. The main body folding material forms a gate main body in which a telescopic member is arranged which is telescopically connected in a diagonal lattice shape with a large number of telescoping arms, and the telescopic member of this gate main body is connected to the main body folding material. Stopper holes are respectively drilled near the upper and lower ends, and bolts and nuts at the upper and lower intersections of each telescoping arm are passed through each of the stopper holes so that the gate slides vertically during expansion and contraction. A waterproof bellows sheet is stretched on the front surface of the main body via sheet attachment members that are elastically fixed to the upper and lower ends of the fixed pillar, movable pillar, and hanging pillar, and is further attached to the hanging pillar of the gate main body. A plurality of reinforcing tubes with support tubes are mounted on the rear hook.

To be able to carry into a site, etc., and also to rotate a gate body and a bellows sheet, which are reduced in size when opened, to the inside of a construction site, etc. Also, when extending, the bolts and nuts at the upper intersection of each telescoping arm slide downward and stop at the bottom of the stopper hole, and at the same time, the bolts and nuts at the lower intersection of each telescoping arm slide upward and stop at the bottom of the stopper hole. It is stopped at the upper part, and when it is contracted, it acts in the opposite direction to that when it is expanded. Furthermore, it functions as a cannula, making it possible to significantly strengthen and strengthen the gate body.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

In the figure, A is a gate body, and this gate body A has three hinge clamps 1 on one side (rear side) for fixing to temporary enclosure pipes P1, P2, etc. at entrances and exits of construction sites, trucks, etc. C-shaped steel fixed columns 2 are attached at appropriate intervals in the vertical direction and rotatable to the rear, and casters 3 are attached to the lower ends, and handles 4 are attached to the front and rear surfaces of approximately the center in the vertical direction.
Between the movable column 5 of the shaped steel and the other side (ventral surface), 9 hanging columns 6 and 10 main body folding members 7 arranged alternately expand and contract in a diagonal lattice shape with 24 telescoping arms 8. It is formed so that freely connected telescopic members 9 are disposed therein.

That is, the hanging column 6 of the expandable member 9 is formed so that a pair of main columns 10 made of channel steel face each other, and the upper and lower ends of the main columns 10 are connected by a horizontal bar 11.
Further, the main body folding material 7 has a flat plate shape and is connected to the hanging pillar 6.
It is slightly shorter than the length of , and stopper holes 12 are formed near the upper and lower ends, respectively.
Furthermore, the extendable arm 8 has a flat plate shape and has different lengths.
For example, there are 16 pieces for 6 lattice parts, 4 pieces for 4 lattice parts, and 4 pieces for 2 lattice parts, and the 4 pieces for the 2 shortest lattice parts. are arranged at the four corners of the telescopic member 9, four pieces for the next four longest lattice parts are arranged inside them, and 16 pieces for the six longest lattice parts are arranged inside them. Connect in a shape. In addition, in order to make the telescoping arms 8 telescopic, each telescoping arm 8 is crossed at four points at the positions of the hanging pillar 6, fixed pillar 2, and movable pillar 5, and each intersection of the telescoping arm 8 is made swingable. The second intersection from the bottom is swingably supported by bolts 13 and nuts on the hanging column 6, fixed column 2, and movable column 5, while at the position of the main body folding material 7. Each telescoping arm 8 intersects at three points, and each intersection of the telescoping arm 8 is swingably supported by a bolt 14 and a nut. 12 and is formed to slide vertically when expanding and contracting.

Then, on the front surface of the gate main body A, a bellows sheet B made of a waterproof synthetic fiber waterproof cloth with ventilation slits is fixed to the upper and lower ends of the fixed pillar 2, movable pillar 5, and hanging pillar 6 in a flexible manner. It is stretched through a mounting member 15.

That is, as shown in FIG.
20 sheet folding materials 17 on top and bottom with
and 12 sheet holding tubes 19 having approximately the same length as the fixed column 2, movable column 5, suspension column 6, etc., and having threaded portions 18 at the upper and lower ends, and each of the upper and lower sheets can be folded. Cylindrical portions 16 at one end of the material 17 adjacent to each other
are connected via bolts 21 and nuts 22 to seat mounting brackets 20 with U-shaped sides fixed to the upper and lower ends of the fixed column 2, movable column 5, and hanging column 6, respectively, and the upper and lower sheet folding materials 17 adjacent cylindrical portions 16 at the other end are matched with each other, and the matched cylindrical portions 16 of the upper sheet folding material 17 and the lower sheet folding material 1 are aligned.
A seat holding tube 19 is attached to each of the matched cylinder portions 16 of 7.
The threaded portions 18 at the upper and lower ends of the two are inserted and connected with nuts 23, respectively.

In addition, a reinforcing tube 25 is mounted on each hook 24 attached to the rear surface of each hanging column 6 of the gate body A near the second intersection from the bottom of the telescopic arm 8, and the tips of a plurality of hooks 24 are A floating prevention fitting 26 of the reinforcing pipe 25 is removably connected to the reinforcing pipe 25, and a plurality of pipes whose lower ends are pivotally supported on ground stakes, anchor bolts, etc. are installed at appropriate locations on the reinforcing pipe 25. The upper end of the support tube 27 is fixed.

(Effect of the invention) Since this invention is configured as described above, when used for single-opening, each hinge clamp 1 of the fixed pillar 2 of the gate body A is temporarily attached to one side of the entrance/exit of a construction site or a truck. The gate main body A and the bellows sheet B are tightened and fixed to the surrounding construction pipe P1 etc. so that they rotate inward when opened, and the opening/closing operation is performed by holding the handle 4 of the movable pillar 5 of the gate main body A and expanding and contracting it. The movable pillar 5 of the gate body A is received by a lock fitting 28 attached to the other temporary enclosure pipe P2 or the like at the entrance/exit of a construction site, truck, etc. In addition, when used for double-door doors, the fixed pillars 2 of both gate bodies A should be placed so that the one for single-door doors is opposite to the temporary enclosure pipes P1, P2, etc. at both entrances and exits of construction sites, trucks, etc. Tighten and fix the hinge clamps 1, respectively, so that both movable columns 5 meet in the middle of the entrance/exit. On the other hand, when not in use, by loosening the hinge clamp 1 of the gate body A, it can be removed from the temporary enclosure pipes P1 and P2 at the entrance to a construction site or a truck. In other words, it can be fixed or removed simply by tightening or loosening the hinge clamp 1 of the gate body A.
It is extremely easy to attach and detach the temporary fence pipes at the entrances and exits of construction sites and trucks.

Moreover, since the waterproof bellows sheet B is stretched over the front of the gate body A using the sheet mounting member 15, the construction site, etc. can be hidden from view from the outside, and there is no beam installed on the top of the gate body A. Therefore, even tall items can be brought into construction sites, making it ideal for entrances and exits of construction sites and trucks.

In addition, the gate main body A and the bellows seat B can be expanded and contracted by the telescopic member 9 and the seat attachment member 15, and the casters 3 are attached to the lower end of the movable column 5 of the gate main body A, so that the gate main body A can be opened and closed. Operation is extremely smooth and quick. In addition, by attaching an appropriate number of hinge clamps 1 to one side of the fixed pillar 2 of the gate body A at appropriate intervals in the vertical direction and rotatably rearward, the gate body A and the bellows sheet are reduced in size when opened. Since B can be rotated to the inside of the construction site, etc., the frontage of the entrance can be used widely.

Furthermore, the main body folding material 7 of the expandable member 9 of the gate main body A
Stopper holes 12 are respectively drilled near the upper and lower ends of the arm, and bolts 14 and nuts at the upper and lower two intersections of each telescoping arm 8 are passed through each stopper hole 12 so that the arm slides in the vertical direction during expansion and contraction. Due to this structure, when extended, the bolts 14 and nuts at the upper intersection of each telescoping arm 8 slide downward and are stopped at the bottom of the stopper hole 12, and at the same time, the bolts 14 and nuts at the lower intersection of each telescoping arm 8 slide downward. It slides upward and is stopped at the upper part of the stopper hole 12, and when it is contracted, it acts in the opposite way to the above-mentioned expansion, so that the expansion and contraction action of the expansion and contraction member 9 of the gate body A can be extremely smooth and reliable.

In addition, the hook 24 on the rear surface of the hanging pillar 6 of the gate body A
By mounting a plurality of reinforcing tubes 25 with support tubes 27 on top, the gate main body A can be reinforced extremely robustly by functioning as a cane, which is extremely convenient during typhoons and the like. In this case, the floating prevention metal fitting 26 can also prevent the reinforcing tube 25 from floating.

As explained above, according to this invention, it is not only extremely easy to attach and detach the temporary enclosure pipes, etc. at the entrances and exits of construction sites and trucks, etc., but it is also ideal for the entrances and exits of construction sites and trucks, etc. Moreover, the opening/closing operation is extremely smooth and quick, and the frontage of the entrance/exit can be used widely.Furthermore, the expansion/contraction action of the expansion/contraction member of the gate body is extremely smooth and reliable, making it extremely convenient even during typhoons.
