Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for an anchor pressure receiving plate which is excellent in aesthetics and can sufficiently cope with changes in the slope of the slope.

[0002]

2. Description of the Related Art As methods for stabilizing slopes, there are a vegetation method, a method of constructing a method frame, a method of arranging concrete blocks and the like.

The method of constructing a method frame requires a great deal of labor for installing and assembling the formwork on the slope, and also involves a risk of spraying mortar.

The construction method for placing concrete blocks is
This concrete block is often arranged as an anchor pressure plate.

FIGS. 6 and 7 show a typical example of an anchor pressure receiving plate 1 made of a concrete block. As a plan view, the anchor pressure receiving plate 1 is composed of a base portion 2 and a cross-shaped leg portion 3 extending radially from the base portion 2. The base 2 is formed with an anchor insertion hole 4 through which a tension member 5 as an anchor is inserted.

A large number of the anchor pressure receiving plates 1 are arranged adjacent to each other so that one side of the cross forms a line along the length direction of the slope (L direction). Further, when the ground proof stress of the slope is small, the load can be reduced and the anchors can be arranged in a staggered manner in order to increase the number of anchors.

The anchor pressure receiving plate 1 has, for example, a side length of about 2 to 3 m, and a thickness of 400 to 600 at the central portion.
mm, 250 to 350 mm at the end, and a downward slope is formed toward the end.

At the time of construction, a wire is hung on a hanging bolt planted on each foot surface of the anchor pressure receiving plate 1 and is lifted by a crane or the like to be placed at a predetermined position.

Then, or simultaneously, in parallel, a tension member 5 such as a steel rod is inserted into the anchor insertion hole 4 and an anchor body 6 is formed at the tip end thereof by pouring cement milk or the like, and at the same time, A pressure bearing plate, in which an anchor head such as a nut is housed in a recess formed in the base 2, is fixed in a state in which a tensile force is applied between the pressure support plate and the anchor body 6 with the bottom surface of the recess as a seat. These anchors are performed for each block.

[0010]

The anchor pressure receiving plate 1 is preferably small from the viewpoint of landscape protection and can be installed stably without being affected by uneven ground. However, if the pressure receiving plate itself is made small, the pressure receiving pressure is small and the pressure receiving plate itself may move.

Further, in order to prevent the soil between the anchor pressure receiving plates 1 from coming off, the anchor pressure receiving plates 1 should be installed as close as possible, that is, the legs 3 should be close to each other. Therefore, the area occupied by the anchor pressure receiving plate 1 is large on the ground, and the scenery becomes poor.

The present invention eliminates the disadvantages of the above-mentioned conventional example, the anchor pressure receiving plate itself is made small, and the landscape protection can be improved, and the movement of the pressure receiving plate and the removal of the soil between the pressure receiving plates are prevented. An object of the present invention is to provide a support structure for an anchor pressure receiving plate.

[0013]

In order to achieve the above-mentioned object, the present invention firstly sewes anchor pressure plates abutting against the ground at appropriate intervals with wires or steel materials. Secondly, the anchor pressure receiving plate has a rectangular shape, and is connected side by side like a tread of a rope ladder.
First, the wire or the steel material is placed in the bag body and the solidified material is filled in the bag body. Fourthly, the bag body is expanded by the solidified material press-fitting at the portion outside the through portion of the anchor pressure receiving plate. It is a summary.

According to the first aspect of the present invention, the anchor pressure plates that are in contact with the ground at appropriate intervals are connected to each other by sewing with a wire or a steel material, so that the size is small. Even objects can be fixed so that they do not move.

Since the size of the anchor pressure receiving plate itself is small, it can be scattered on the ground,
The landscape is protected. Moreover, the small size of the anchor pressure receiving plate itself enables the installation without being affected by the unevenness of the ground surface.

Further, even if there is a space between the anchor pressure receiving plates, it is possible to prevent the soil from coming off by disposing the wire or the steel material on this portion.

According to the present invention as set forth in claim 2, in addition to the above-mentioned action, the anchor pressure receiving plate is connected in a sewn manner with a wire or a steel material, and has a rectangular shape so that two positions are stable. You can connect with.

According to the third aspect of the present invention, if the wire or the steel material is used alone, the wire or the steel material expands or contracts due to the temperature difference, and when these are directly fixed to the anchor pressure receiving plate, the anchor pressure receiving plate is rather returned. May move. Therefore, the wire or steel material is placed in the bag body, and the bag body is inflated by filling the bag body with a solidifying material, which connects the anchor pressure plate to each other, and the change in the wire or steel material directly affects the anchor pressure plate. I tried not to convey it.

According to the present invention as set forth in claim 4, the anchor pressure receiving plate can be firmly fixed by expanding the portion of the bag outside the penetrating portion of the anchor pressure receiving plate by press-fitting the solidifying material.
