Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retaining wall used for installing a formwork on a retaining wall, such as an L-shaped retaining wall, and then pouring concrete thereon to increase the height of the retaining wall. The present invention relates to a member for setting a formwork on the upper side.

[0002]

2. Description of the Related Art As shown in FIG. 3, an L-shaped retaining wall 70 is formed by integrally forming a concrete bottom plate 71 and a retaining wall 73 in an L-shape. A large number of joints are provided on the boundary line of the embankment portion such as a school, a school, a roadway, etc. while joining the joining surfaces 75, 75 on both sides thereof,
The soil is applied to the portion H on one side, and is used to securely support the embankment by the retaining wall 73.

If it is necessary to make the embankment higher than the height of the retaining wall 73, a concrete form is attached to the upper side of the retaining wall 73 and concrete is poured in before embankment. It is necessary to further increase the height of the retaining wall 73.

[0004]

However, the retaining wall 73
Is usually several meters high, and mounting a formwork thereon requires a rather complicated and potentially dangerous operation such as installing a scaffold on the bottom plate 71.

The present invention has been made in view of the above points, and an object of the present invention is to provide a member for installing a formwork on a retaining wall, which can easily install the formwork on the retaining wall. It is in.

[0006]

In order to solve the above-mentioned problems, the present invention has a rod-like or plate-like shape, the entire shape of which is formed in a U-shape so as to straddle the upper side of the retaining wall. At least one end thereof is bent in a direction away from the retaining wall to form a scaffolding plate holder, and further, a guide portion for supporting a formwork is provided on each of the upper corners of the U-shape. A member for installing the formwork on the wall was constructed. In this case, the formwork setting member is divided into two parts either at its upper side or at the corners at both ends of the upper side, and the divided parts are joined by engaging / removable connecting means.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view showing a mold setting member 10, a mold 51, and the like according to an embodiment of the present invention. FIG. 2 is a side view of the mold setting member 10.
As shown in both figures, the form-installing member 10 is composed of a first member 11 and a second member 31.

Here, the first member 11 is formed by bending a rod member at a substantially right angle to form a corner 17 between the upper side 13 and the side 15.
The scaffold plate holder 19 is formed by bending the lower end of the side portion 15 outward at a substantially right angle, and the tip is slightly bent upward.

Further, a female screw (coupling means) 21 is provided on a tip end surface of the upper side portion 13. The corner 17
At the upper part, a guide portion 23 which is bent in a substantially U-shaped cross section and has an upward opening is attached. The inner surface of the guide portion 23 is drawn downward to form a retaining wall contact portion 25. At the top of the outer surface is a mounting hole 2
7 are provided. Further, a plate 29 for preventing rocking is mounted on the scaffold plate holder 19.

On the other hand, the second member 31 forms a side portion 33 and a scaffold plate holder 35 by bending the rod member into a substantially “L” shape, and the tip of the scaffold plate holder 35 is slightly upward. It is configured to be bent. A plate 45 for preventing rocking is also attached to the scaffold plate holder 35.

A guide portion 39 having the same shape as the guide portion 23 is attached to the upper end of the side portion 33. The inner surface of the guide portion 39 is drawn downward to form a retaining wall contact portion 41. A mounting hole 43 is provided in the upper part of the outer surface. A male screw (coupling means) 37 screwed to the female screw 21 is provided to project from the upper end of the side portion 33 toward the first member 11.

Next, a description will be given of a method of using the member 10 for setting a form. That is, first, as shown in FIG. 3, a large number of L-shaped retaining walls 70 are installed side by side while joining the joint surfaces 75 on both sides thereof.

Next, as shown in FIG. 1, a cylindrical PVC tube 40 (having the same length as the width of the retaining wall 73) is inserted into the upper side portion 13 of the first member 11, and the end of the cylindrical tube 40 is formed. The male screw 37 of the second member 31 is inserted into the female screw 21, and the second member 31 (or the first member 11) is screwed and integrated by rotating.

The screwing of the two is performed to a position where the two retaining wall contact portions 25 and 41 respectively contact both surfaces of the retaining wall 73 (that is, both ends of the cylinder 40) and clamp the same, or to the vicinity thereof.

As a result, the form-mounting member 10 is integrated, and as a whole, is formed in a substantially "U" shape so as to straddle the upper side of the retaining wall 73 as shown in FIG. The form-mounting member 10 is attached to a plurality of locations on the retaining wall 73 provided side by side. And both scaffold board holders 19, 35
The scaffolds 50, 50 are placed on top. The scaffold plates 50, 50 are prevented from swinging left and right (in FIG. 4, in front and back of the paper) by the plates 29, 45. And the scaffold plates 50,5
A person climbs on 0 and performs the following work.

That is, as shown in FIGS. 1 and 4, the molds 51, 51 are inserted into the respective guides 23, 39, and the mounting holes 27, 43 provided in the guides 23, 39 and the molds 5 are formed.
The pins 55 are inserted into the holes 53 provided in the holes 1 and 51 to fix them.

On the molds 51, 51, if necessary, another molds 51, 51 are stacked by a required number and fixed by a desired fixing method (not shown) to a desired height.

Then, concrete is poured between the forms 51, 51 and solidified to increase the height of the retaining wall.
After the first member 51 and the scaffold plates 50 are removed, the second member 31 is rotated by rotating the second member 31 (or the first member 11), and the second member 31 is removed as it is. The member 11 is removed from the tube 40 and removed. The tube 40 is fixed in the cast concrete as it is and serves as a drain hole.

In the above embodiment, the mold setting member 10 is divided into two parts at the portion where the guide part 39 is provided.
The portion provided with the guide portion 23 may be divided into two parts. Also, the portion to be divided may be the portion of the upper side portion 13, but if it is divided into two in particular at any one of the guide portions 23 and 39, that is, at any one of the upper corner portions, the detachment can be easily performed, It is suitable.

Further, in the above embodiment, the member 10 for setting the form is used.
Is formed by a rod, but may be formed by a plate. Further, it is also possible to extend the side portions 15, 33 from below the scaffold plate holders 19, 35, and to attach a diagonal bar between the extended portion and the scaffold plate holders 19, 35 to reinforce this. good.

In the above-described embodiment, the member 10 for setting the form is used.
Although the scaffold plate holders 19 and 35 are provided on both sides of the frame, they may be provided only on one side.

It is needless to say that the retaining wall to which the present invention is applied is not limited to the L-shaped retaining wall, but may be used for other various retaining walls.

[0023]

As described in detail above, according to the present invention, it is possible to easily install a formwork on a retaining wall, and it is safe, easy and quick to place concrete on the retaining wall. It has an excellent effect that it can be performed.
