Abstract

PROBLEM TO BE SOLVED: To reduce the weight of a work fence to improve the setting, removing and moving properties thereof and stably and firmly support the fence. SOLUTION: This support base for work fence comprises a base part 1 molded into a hollow body having a reinforcement rib 5 arranged on the reverse side so as to have proper rigidity, size and height by use of a resin as material, and two support cylinders 3 having inside diameters substantially equal to the outer shape of the leg part of a fence, which are arranged in row on the upper surface of the base part 1, and the leg parts 10 of the fences 9 are fitted to the support cylinders, respectively to continuously raise the fences in the extension direction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for a construction fence which is used, for example, when a fence is installed so as to surround a construction site. The feature is that.

[0002]

2. Description of the Related Art Conventionally, a support for a construction fence has been made of, for example, concrete having a hole into which a leg of the fence is fitted, or iron made by cutting an H-shaped steel into an appropriate length.

[0003]

Since the construction fence is temporarily installed, the use of concrete or iron for the support base increases the weight. However, there is a disadvantage that a great deal of labor is required when removing after completion. In addition, sandbags and blisters placed on a relatively lightweight support base formed in a flat shape may cause problems such as inconvenient treatment of soil and water used for weight. was there.

[0004] In view of the above, the problem to be solved by the present invention is that it is lightweight and convenient to carry, can firmly attach and detach and support the fence legs, can be easily installed and removed, and has a small space. In some cases, there is a need to develop a support for a construction fence that can eliminate the need for placing weights.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a fence on the upper surface of a base made of resin and having a hollow body having appropriate rigidity, size and height with reinforcing ribs disposed on the back surface. Two supporting cylinders having inner diameters substantially equal to the outer shapes of the legs are provided side by side, and the legs of the fence are fitted to the supporting cylinders, respectively, so that the fences are erected continuously in the extending direction. And a support for the construction fence.

The support base of the present invention constructed as described above is relatively lightweight because it is entirely made of resin. for that reason,
Easy to transport, install and remove. Since the legs of the fence are fitted to and supported by the support cylinder provided on the support base, the fence can be stably installed and can be firmly erected.

On one side of a plane portion provided with two support cylinders, a slope portion having a large number of anti-slip projections is extended,
According to the second aspect of the present invention in which the slope portion can be used as a weight mounting table, the entire base portion is eccentric toward the slope portion side. When the eccentric slope is used as a weight mounting table, the weight is prevented from slipping on the mounting table, and the operation of mounting and removing the weight is easy.

[0008] A plurality of insertion holes for pegs are formed on the upper surface of the base, and the support table is fixed at a desired installation position by pegs driven into the installation surface through the insertion holes. According to the invention of item 3, when a sandbag or a waterbag cannot be used as the weight for supporting the fence, a peg is driven into the insertion hole on the upper surface of the base to fix the support on the installation surface. Can be.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an embodiment, FIG. 2 is a longitudinal elevation view along a length direction, and FIG. 3 is a cross-sectional elevation view showing a use state.

In FIG. 1, reference numeral 1 denotes a resin base, and FIG.
As shown in the figure, a rib 2 for reinforcement is provided on the back surface to provide rigidity and to an appropriate size, for example, a height 3
It is formed to have a thickness of 0 mm, a width of 150 nn, a length of 300 mm, and a thickness of about 4 mm for each part. Reference numeral 3 denotes a flat part 4 formed on the right side of the base part 1 in the drawing, and reinforcing ribs 5 are similarly arranged on the peripheral surface.
Two support cylinders 6 provided at a height of 0 mm, a slope portion eccentrically extended to one of the flat portions 4, and a number of anti-slip projections 7 arranged from the slope portion 6 to the flat portion 4 , 8
Are insertion holes for pegs which are respectively opened at four corners of the base 1 formed in a substantially rectangular shape.

As shown in FIG. 3, the supporting base having the above-described structure is provided on one supporting cylinder 3 with one leg 10 of the fence 9.
And the other support tube 3 is fitted with another leg 10 of a fence 9.
The fence is used to connect the fences in the extension direction. Needless to say, the fence 9 can be extended in a desired angle direction from the support base.

When a weight is needed to support the standing fence 9, a sandbag or a waterbag is placed on the sloped portion 6, and the antiskid protrusion 7 prevents the weight from slipping to compensate for the lack of weight. When it is difficult to use a sandbag or a waterbag, and if it is possible to drive a peg into the installation surface, drive the peg into the through holes 8 at the four corners.
The support base can be fixed on the installation surface.

In carrying out the present invention, the shape of the base 1 is not limited to the illustrated embodiment, but may be changed to an arbitrary shape such as a disk, an ellipse, or a square.
Needless to say, the length, thickness, interval, and the like of the support cylinder 3 can be changed in design. The resin for forming the support is preferably PC, POM, 6NY, or the like.

[0014]

According to the present invention constructed as described above and used as described above, the weight of the support for the construction fence can be reduced. Therefore, transportation, installation, movement, and removal as equipment used for temporary construction are facilitated. Further, since the legs of the fence are fitted to and supported by the support cylinders provided on the support table, the fence can be stably installed and a strong standing can be obtained.
