Description

[Detailed Description of the Invention] The present invention relates to a temporary fencing structure that constitutes a temporary fencing for temporarily enclosing or dividing a construction site such as road work or construction work, or other areas.

FIG. 1 shows a conventional fencing structure 1 of this kind. This fencing structure 1 consists of a first structure in which one ends of two linear members 2a and 2b are connected to each other so as to be openable and closable. legs 2 and 2
A second leg 3 formed by opening and closing one end of the linear members 3a and 3b of the book, and an upper horizontal member 4 and a lower horizontal member 5 attached between these legs 2 and 3. , 6, and other members.

When constructing a temporary fence using the conventional temporary fence structure 1, in many cases, a plurality of temporary temporary structure structures 1 are arranged in a straight line as shown in FIG. A temporary fence was constructed by attaching a pipe material 7 to an upper horizontal member 4 with a wire 8 or the like across the temporary fence structure 1.

However, such a conventional temporary structure 1 has the following various drawbacks.

(b) If there is a step on the installation surface, the pipe material 7 is placed between the temporary structure 1 placed on the high part of the installation surface and the temporary structure 1 placed on the low place of the installation surface. Since it cannot be installed across the gap, the temporary structure must be discontinuous at the step.

(b) Since the pipe material 7 can only be attached to the temporary fencing structure 1 in a direction parallel to the upper horizontal material 4, even if there is no step on the temporary fencing installation surface, the temporary fencing structure can be attached as shown in Figure 3. When trying to bend one row, one pipe material cannot be attached across two temporary fencing structures 1 at the bending part A.
In this case, temporary scaffolding must be discontinuous.

(C) The pipe material 7 causes the center of gravity to shift upward, making it unstable and prone to falling over, so it is necessary to stabilize the lower horizontal members 5 and 6 by placing the earthenware 9 on them as shown in Figure 2. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a temporary structure that can overcome the various drawbacks of the conventional structures.

The temporary fence structure according to the present invention includes a first leg member, a second leg member, an upper binding material attached between the upper ends of both the leg members, and an upper binding member attached between the lower end portions of the both leg members. a lower connecting member; an upper support that is erected on the upper connecting member or the first leg member and extends in the vertical direction, and to which a pipe material is laterally attached via a fitting; and the lower connecting member; The pipe material is erected on the pipe material and extends in the vertical direction, and the mounting member has a lower support to which a pipe material different from the pipe material can be laterally attached via the tool. Each of the mounting tools includes a first clamping member and a second clamping member coupled to each other, and is rotatably supported by the first clamping member, and together with the second clamping member, a third clamping member that sandwiches the pillar or the lower pillar; a fourth clamping member that is rotatably supported by the second clamping member and that sandwiches the pipe material together with the second clamping member; Bolts and nuts for tightening the first clamping member and the third clamping member so that the upper strut or the lower strut is clamped between the clamping member and the third clamping member; and the second clamping member. and a bolt and a nut for tightening the second clamping member and the fourth clamping member so that the pipe material is clamped between the upper strut and the lower strut. At least each of the attachments has a length that allows attachment of two or more tools.

Hereinafter, the present invention will be explained in more detail based on embodiments shown in the drawings.

4 and 5 show an embodiment of the fencing structure according to the present invention.

In these figures, between the upper ends of the first leg member 11 and the second leg member 12 each made of round pipe material,
A plate-shaped upper binding material 13 connects both ends of the plate-shaped upper binding material 13 to the both leg members 1.
It is attached horizontally by welding to the upper end of the 1°12.

Further, between the lower end portions of the leg members 11 and 12, a lower bonding member 14 made of channel material is horizontally attached by welding both ends to the leg members 11 and 12.

Here, the spacing between the leg members 11, 12 is narrow at the top and widens toward the bottom.

An upper support 15 made of a round pipe material is erected at a portion of the upper binding material 13 directly above the first leg member 11 by welding its lower end to the upper binding material 13, It extends in the vertical direction.

The upper support 15 may be erected directly on the first leg member 11, or the upper support 15 may be erected on a portion of the upper binding material 13 that is not directly above the first leg member 11. You may.

Further, the upper end of the upper support column 15 is open, and normally this opening is covered with a lid 16.

A lower support 17 made of a round pipe material is erected on the lower binding material 14 by welding its lower end to the lower binding material 14, and extends in the vertical direction.

The upper support 15 and the lower support 17 each have a length that allows attachment of at least two attachment tools 18, which will be described below.

Reference numeral 18 in FIG. 6 shows an example of a mounting tool used when constructing a temporary fence using the temporary fence structure 10 (this mounting tool 18 itself is conventionally known).

Next, to explain the mounting tool 18, the first clamping member 19 and the second clamping member 20, which are curved in a roughly dogleg shape, are fixed to each other.

At one end of these clamping members 19 and 20, one end of a third clamping member 21 and a fourth clamping member 22 are rotatably supported via pins 23 and 24, respectively. Recesses 25 and 26 are provided at the other ends of the members 21 and 22, respectively.
is provided.

Furthermore, one end of a tightening member 27.28 is rotatably supported at the other end of the clamping members 19, 20 via a pin 29.30, and the bolt 27.2 is rotatably supported via a pin 29.30.
Nuts 31 and 32 are screwed into 8.

Here, the first clamping member 19, the third clamping member 21, and the pins 23, 29, the second clamping member 20, the fourth clamping member 22, and the pins 24, 30 are oriented at 90 degrees to each other. are different.

Then, with the support column 15.17 or the pipe material sandwiched between the first clamping member 19 and the third clamping member 21, the bolt 27 is inserted into the recess 25, and then the nut 31 is tightened. By pressing the rotating member 21 from the outside, the supports 15, 17 or the pipe material can be held between the first holding member 19 and the third holding member 21.

In exactly the same way, with the support column 15.17 or pipe material sandwiched between the second clamping member 20 and the fourth clamping member 22, the bolt 28 is inserted into the recess 26, and then the nut 3 is inserted.
2 and presses the fourth clamping member 22 from the outside with the nut 32, the strut 15.17 or the pipe material is clamped between the second clamping member 20 and the fourth clamping member 22. be able to.

Therefore, as described above, for example, between the first clamping member 19 and the third clamping member 21, the struts 15 or 17
If the pipe material is held between the second holding member 20 and the fourth holding member 22, the pipe material can be attached to the support 15 or 17 via the tool 18. .

FIG. 7 shows an example of a temporary structure made up of the above-mentioned temporary structure structures 10, and shows an appropriate number of upper supports 1 of the temporary structure structures 10
5, one or two pieces each are attached horizontally to the pipe materials 33, 36, 37 via the fittings 18, and one piece each is attached to the lower support 17 of each temporary structure 10. The pipe material 34.3 is attached via the fitting 18.
8 are attached horizontally to form a temporary fence (35 is a sign board suspended from pipe material 33, 37).

Note that the spacing between each temporary fence structure 10 can be freely adjusted depending on the situation.

In this way, according to the temporary fence structure 10, pipe material can also be attached to the lower part of the structure 10 using the lower struts 17, which allows the center of gravity of the temporary fence to be located downward, unlike the conventional method. It is possible to prevent the temporary scaffolding from falling down without using a straw mat or the like.

Furthermore, by attaching pipe material to the lower part of each temporary fence structure 10 in this way, the strength of the temporary fence can be improved and it is also possible to prevent people from passing through it.

Furthermore, as shown in part B of FIG. 7, for example, the two fittings 18 are attached to the upper support column 15 so as to form arbitrary angles to each other, and furthermore, these two fittings are attached to the fittings 18.
By attaching different pipe materials 36, 37 to the two pipe materials 36, 37, it is possible to connect the two pipe materials 36, 37 so as to make an arbitrary angle to each other.

Therefore, the temporary fence can be bent at any angle and the temporary fence can be prevented from becoming discontinuous even at the bent portion.

In addition, in FIG. 7, in order to avoid cluttering the diagram, only one attachment 18 is attached to the lower support 17, but the lower support 17 also has the same attachment as the upper support 15. Similarly, the two fittings can attach fittings 18, and these fittings can each attach one piece of pipe material to fittings 18.

Figure 8 shows the temporary structure 1 when there is a step on the installation surface.
An example of the structure of a tent made by 0 is shown below.

As shown in the figure, even if there is a step C, in the temporary structure 10 installed at a high place, the support columns 15, 17
The installation tool 18 is attached to the lower part of the structure, while the support 15.1 is
By attaching the fitting 18 to the high position of the pipe material 39.7, the pipe material 39.
40 can be passed over, making it possible to continue the temporary scaffolding even at stepped sections.

In addition, in the installation shown in FIG. 6, the members corresponding to the first clamping member 19 and the second clamping member 20 in the tool 18 are
When mounting a type of structure that can be rotated with respect to each other using a tool, the posts 1 should be attached to both the elevated structure 10 and the lower structure 10.
5. For attachment to 17, even if the mounting position is the same, the pipe material can be passed between the two horizontal bodies 10 (in this case, the pipe material is passed between the two horizontal bodies 10). (The pipe material is tilted with respect to the horizontal direction.)

In addition, in this temporary scaffold structure, the first leg member 11
Since the upper binding material 13 is attached between the second leg members 12, when installing the pipe material, if the pipe material is placed on the upper binding material 13, each temporary structure structure 10 can be attached. It can be kept standing on the temporary fence installation surface.

Therefore, when installing pipe materials, there is an inconvenience that one worker must be attached to each temporary fence structure 10 and each worker must hold each temporary fence structure 10 by hand. can be avoided.

In addition, in this temporary scaffold structure, the first leg member 11
Since the upper binding material 13 and the lower binding material 14 are attached between the second leg member 12, when attaching the pipe material to the lowest part of the upper strut 15 and the lower strut 17, the attachment is performed using the fitting 18. By attaching it to the upper strut 15 and lower strut 17 while being placed on the upper binding material 13 and the lower binding material 14, the resulting temporary structure can be made more robust.

In addition, in the assembly example shown in the drawings, a plane including the temporary scaffolding structure 10 (leg members 11, 12, binding materials 13, 14, struts 1
5, 17... The plane including the lower support struts) is assembled so that it is perpendicular to the pipe materials 33, 34, 37, 38, 39°40, so the depth of the temporary structure itself (
(dimensions perpendicular and horizontal to the pipe material) will be relatively large, but if this is inconvenient, install the temporary structure 10 by loosening the nuts of the tool 18 and attaching it to the support 15.17.
If the plane containing the wainscot board structure 10 is rotated at an appropriate angle around
The depth of the temporary fence itself can be reduced.

In addition, such measures cannot be taken even after the bolts and nuts of the installation tool 18 have been tightened and the temporary structure has been completed.
It can be carried out by loosening bolts and nuts as necessary, and multiple temporary fencing structures 1 constituting one temporary fencing can be carried out.
It is also possible to take such measures only for the necessary temporary fence structures 10 out of 0, and reduce the depth of only the necessary portions of the temporary temporary fence having a certain length.

Furthermore, according to this embodiment, the upper support 1 as shown in FIG.
The flashing light 41 can be attached to the temporary structure 10 very easily by removing the lid 16 covering the top support 5 and fitting the lower end of the flashing light 41 to the inner peripheral surface of the upper support column 15.

It goes without saying that the attachment tools used when constructing a temporary fence using the temporary fence structure according to the present invention are not limited to those shown in FIG. 6 above.

As described above, the temporary fence structure according to the present invention can (a) prevent the temporary fence from becoming discontinuous even at stepped portions;

(b) The temporary fence can be bent at any angle and the temporary fence can be prevented from becoming discontinuous even at the bent portion.

(c) When installing the pipe material, if the pipe material is first placed on the upper binding material, each temporary fence structure can be maintained in a standing state on the temporary fence installation surface.

This avoids the inconvenience of having one worker attached to each temporary structure and having to hold each temporary structure by hand when installing pipe materials. be able to.

2) When installing pipe material at the lowest part of the upper and lower supports, attach it to the upper and lower supports with the fittings placed on the upper and lower binding materials, and the temporary The frame can be made more robust.

(E) If necessary, attach the pipe material to the temporary fencing structure using tools, with the plane containing the temporary fencing structure facing diagonally to the pipe material. Depth of the temporary fence itself (dimension in the horizontal direction perpendicular to the pipe material)
can be made smaller.

In addition, such measures do not require that the bolts and bolts of the mounting
Even after tightening the nuts and completing the temporary installation, you can loosen the bolts and nuts if necessary.
In addition, such measures are taken only for necessary temporary structures among the multiple temporary structures that make up one temporary structure,
It is also possible to reduce the depth of only the necessary part of a temporary fence of a certain length.

(f) Even if you do not use a straw mat, etc., there is no risk of the temporary scaffolding falling over.

(g) The spacing between the temporary fence structures can be adjusted freely depending on the situation.

This provides an excellent effect.
