Abstract

PROBLEM TO BE SOLVED: To facilitate installation working by installing a foundation on ground, supporting a protection fence on the support of the foundation, and connecting to insert a plurality of the foundations through an H-shaped steel insertion cylinder on an H-shape steel. SOLUTION: A support 7 is erected from the upper face of a foundation 1 installed on ground, a protection fence 10 is supported on the upper part of the support 7, and an H-shaped steel insertion cylinder 3 is attached to the upper face or the inside and outside face of the foundation 1. A plurality of the foundations have a prescribed interval to be installed on ground G, and are fixed by an anchor 13 through a fitting 4 on the ground G. The support 7 is inserted in the support attaching cylinder 2 of the foundation 1, and the protection fence 10 is fixed and supported on the upper part of the support 7 by bolts 8 and nuts 9. Furthermore, the H shape steel 5 is inserted in the H-shaped steel insertion cylinder 3 of the foundation 1 to mutually connect a plurality of the foundations 1. Thus, it has the same strength as an angular pipe as a foundation mutual connection means, and since the H-shape steel of the weight not exceeding 70% of the angular pipe is used, the installation working of the protection fence can be made easy.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary support fence support structure.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG.
(21) is provided with a pillar mounting hole (22) from the upper surface, and further the foundation (21)
A support insertion tube (23A) and a square pipe insertion tube (23B) are integrally mounted on the upper surface of the support, and a support post (23A) is inserted into the support mounting hole (22) of the foundation (21) through the support insertion tube (23A). 27), and the support (27)
The protective fence (30) body is fixedly supported by bolts (28) and nuts (29) on the upper part of the square pipe, and a plurality of foundations (21) having such a configuration are connected to the square pipe through the square pipe insertion cylinder (23B). A support structure is provided for the protective fence (30), which is connected through (25). The foundation (21) is installed on the ground G, and anchors (3) are provided via L-shaped fittings (24) attached to the lower side of the foundation (21).
It is fixed to the ground G by 1).

[0003]

The above-mentioned conventional protective fence (30)
In the above supporting structure, the weight of the square pipe (25) was large (about 20 kg / m), and the installation work was difficult. Square pipe
Instead of (25), there is also provided a configuration in which foundations are connected to each other by a groove type rope. In this configuration, the channel rope is connected to the foundation via the bracket by bolts. However, when the automobile collides with the protective fence, the bolts are broken, the interconnections of the foundations are separated, and the foundation moves.

[0004]

According to the present invention, as a means for solving the above problems, a support (7) is erected from the upper surface of a foundation (1) installed on the ground, and the support (7) is provided on the support (7). Guard fence (10)
The main body is supported, and an H-shaped steel insertion tube (3) is attached to the upper surface or the inner and outer surfaces of the base (1).
(1) through the H-shaped steel insertion tube (3) through the H-shaped steel (5)
To provide a support structure for the protective fence (10), which is connected by passing through. The foundation (1) is preferably made of a steel ingot,
Further, it is desirable that a locking means (4) is provided below the base (1).

[0005]

[Function] A plurality of foundations (1) supporting the protective fence (10) are connected by an H-beam (5) through an H-beam insertion tube (3). The H-shaped steel (5) has the same strength as a square pipe and sufficiently withstands the load at the time of collision. Further, the H-shaped steel (5) is lighter than the square pipe (about 14 to 15 kg / m), and the installation work is easy.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in FIGS. 1 to 6. (1) is a foundation, and the foundation (1) is composed of a steel ingot such as an ingot or a billet. Become
A column mounting cylinder (2) is mounted on the upper surface by welding or the like, and a rectangular H-shaped steel insertion tube (3) is further mounted on the upper surface by welding or the like.

Further, a stepped L-shaped bracket (4) as a locking means is attached to the lower edge of the main body of the base (1) by welding or the like. The H-shaped steel (5) has a pair of left and right bolt holes (6) at both ends of the upper surface as shown in FIG.

As shown in FIG. 3 and FIG.
Are installed on the ground G at predetermined intervals, and
It is fixed to the ground G by the anchor (13) via (4). A column (7) is inserted into the column (2) of the foundation (1), and a bolt (8) and a nut are mounted on the column (7).
The protective fence (10) is fixed and supported by (9).

Further, the H-shaped steel insertion cylinder (3) of the foundation (1) has H
A plurality of the foundations (1) are interconnected by the insertion of the section steel (5). As shown in FIG. 5, the H-shaped steel (5) is crossed at the end with a splice plate (11) on the upper surface, and the bolt (12) is inserted through a pair of left and right bolt holes (6).
And fixedly connected by a nut (not shown).

In order to connect the H-beams (5) other than in the above embodiment, a splice plate (11A) is inserted across the end side as shown in FIG. 6 and fixed with bolts (12A) and nuts (not shown). May be connected. Further, the H-shaped steel insertion tube may be attached to the outer surface or the inner surface of the foundation.

[0011]

According to the present invention, since the H-section steel having the same strength as the square pipe and weighing about 70% of the square pipe is used as the means for connecting the foundations, the work of installing the protective fence can be easily performed.
