SUMMARY OF THE INVENTION In view of the above drawbacks, a first object of the present invention is to prevent theft of a plate-like panel while making use of the advantages of the conventional embodiment. Obtaining a temporary gate for the construction site. A second object of the present invention is to provide a temporary gate for a construction site which can easily cope with the need to change the width of the entrance of the construction site or the construction site in accordance with the progress of the construction or the like. It is to get.

[0007]

According to the present invention, a temporary gate at a construction site according to the present invention is formed by combining a plurality of X-type swing arms 3 in which a gate body 1 constituting a temporary gate 1A swings scissors. A telescopic frame 4, a first connecting support rod 7 pivotally connected to one end of the telescopic frame, and having a caster 6 at a lower end thereof;
On the other hand, a second connecting support rod 10 pivotally connecting the other end of the telescopic frame 4 is provided.
And a plurality of foldable panel plates 20 whose ends are fixedly attached to the second connection support rod 10 and the first connection support rod 7, and both end edges of the panel plate 20. The shaft tube 21
The upper and lower portions of both end edges of the panel plate 20 or the portions near the upper and lower portions are provided on the outer end side of the shaft tube portion 2.
1 and a mounting bolt 22 having a bolt portion 24 provided on the inner end side thereof in a direction intersecting with the cylindrical portion 23. A plurality of horizontal through holes are formed in the upper and lower portions or upper and lower portions of the first connecting rod 7 and the second connecting rod 10, and the bolt portions of the mounting bolts 22 penetrating these horizontal through holes 30. via a plurality of fastener to be screwed respectively 24, first the panel plate 20 connected支杆7 and the second
It is characterized in that it is detachably fixed to the connecting support rod 10.

[0008]

In the above construction, each gate body 1 can be expanded and contracted right and left. When each gate body 1 expands and contracts,
The swivel casters 6 slide on the ground, and the unit panels 20a, 20a of each panel plate 20 also open and close.

Next, in the case where the temporary gate 1A is installed at the entrance of the construction or construction site, if a thief tries to remove the panel board 20 from each gate main body 1,
It is impossible for the thief to remove the panel plate 20 from the outside of the gate body 1, and must always get over the temporary gate 1A, and
A plurality of fasteners 31 to be screwed with the bolt portions 24 of each mounting bolt 22 must be removed one by one.

Next, for example, when the width of the doorway is reduced due to the progress of the construction, the nuts of the connected gate body 1 and the connecting means 8 connecting the connected gate members are removed, and the required number of gates are removed. All you have to do is unlink the body. The gate body 1 can be increased by the connecting means 8 when necessary.

The gate body 1 constituting the temporary gate 1A has a telescopic frame 4 formed by combining a plurality of X-type rocking arms 3 that rock with scissors, and a pivotal end of this telescopic frame. And a lower end provided with a horizontal plate 5 interposed therebetween.
Alternatively, the first connecting support rod 7 having two, in this embodiment, one free caster 6, and the other end side of the telescopic frame 4 on the other hand, and the other main body 1 of the same type are connected. A second connection support rod 10 having a plurality of connection holes 9 that can be integrally connected via connection means 8 such as bolts and nuts.

The end of each swing arm 3 constituting the telescopic frame is connected to at least the first connecting support 7 or the second connecting support 1.
0 through a plurality of pivot pieces 11 and 12. Each of the three swinging arms 3 is attached to three upper and lower pivoting pieces 11 that pivotally support one end of the telescopic frame 4 and three upper and lower pivoting pieces 12 that pivotally support the other end of the telescopic frame 4. The guide slots 13 and 14 are formed to guide the end portions in the vertical direction corresponding to the expansion and contraction movement of the expansion and contraction frame 4.

The first connecting support 7 is also connected to the connecting means 8.
There are formed a plurality of connection holes 15 through which other same-type gate bodies 1 can be connected continuously or integrally in an inverted state.

Next, reference numeral 20 denotes a plurality of panel boards whose ends are respectively fixed to the first connecting rod 7 and the second connecting rod 10 so as to be located outside the telescopic frame 4 of each gate body 1. . These panel boards 20 can be wholly or partially removed from the gate body 1 when not needed. Panel board 2
0 denotes a unit panel 20 divided into two as in the conventional embodiment.
a, 20a, and these unit panels 20a, 2a
Oa can be folded through an appropriate hinge (not shown).

First, reference numeral 21 denotes a shaft cylinder portion fixedly provided at the upper and lower portions of the both end portions of the panel plate 20 or near the upper and lower portions. A total of four such shaft cylinder portions 21 are appropriately welded to both end portions of each panel plate 20.

Reference numeral 22 designates a tubular portion 23 located below the shaft tubular portion 21 on the outer end side, and a bolt continuously provided on the inner end side in a direction crossing the tubular portion 23. A mounting bolt having a portion 24. As shown in FIG. 7, the mounting bolt 22 is connected to the panel plate by means of a pivot pin 25 penetrating through the shaft cylindrical portion 21 and the cylindrical portion 23 and a lock nut 26 welded to the lower end of the pivot pin 25 projecting therefrom. 20 are provided integrally.

Reference numeral 30 denotes a plurality of horizontal through holes formed in the upper and lower portions of the first connecting rod 7 and the second connecting rod 10 or near the upper and lower portions. These horizontal through holes 30
Penetrates in the front-rear direction of the gate body 1 as shown in FIG.

Reference numeral 31 denotes a plurality of fixing nuts which are screwed with the bolt portions 24 of the mounting bolts 22 penetrating the horizontal through holes 30. These nuts 31 are located on the back side of the gate body 1.

[0021]

As is clear from the above description, the present invention has the following effects. (1) The plate-like panel 20 can be prevented from being stolen while taking advantage of the advantages of the conventional embodiment. That is,
If the thief attempts to remove the panel board 20 from each gate body 1, the thief cannot remove the panel board 20 from the outside of the gate body 1 without fail, and must climb over the temporary gate 1A, and furthermore, A plurality of fasteners 31 to be screwed with the bolt portions 24 of the bolts 22 must be removed one by one. (2) A plurality of gate bodies 1 of the same type can be integrally connected to the first connection support rod 7 and the second connection support rod 10 via connection means 8 such as bolts and nuts. When the connection holes 15 and 9 are provided, it is possible to easily cope with the case where the width of the entrance of the construction or the construction site has to be changed according to the progress of the construction or the like.
