Abstract

PURPOSE:To enlarge a retaining wall block by a method in which left and right-handed side walls or an intermediate wall is connectedly provided to the front wall of a retaining wall block, coupling grooves are formed on the inner surfaces of the walls and coupled with a closing plate to form a space, and concrete is placed into the space. CONSTITUTION:In a retaining wall block(a) consisting of a front wall 1, left and right-handed walls 2 and 3, and an intermediate wall 4, coupling grooves 2', 3', and 4' are formed in the inner surfaces of the walls 2, 3, and 4 which are facing each other in such a way as to enable coupling positions to be selected. The blocks(a) are set in parallel with a foundation 5, and a closing plate 6 is coupled with the grooves 2' and 3' or between the grooves 2' and 4' and the grooves 3' and 4' to form a space 7 between the wall 1 and the walls 2 and 3 or between the walls 2 and 3 and the wall 4. Concrete 8 is placed into the space 7. A large-size and heavy retaining wall block can thus be set.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of forming a large and heavy concrete block retaining wall.

[Problems to be solved by conventional technology and invention]

Recently, large retaining wall blocks have been frequently used,
The larger the size, the more strength is required.

If the wall thickness is increased to meet the required strength, it will inevitably become very heavy, making it difficult to carry and handle, making construction that much more difficult.

The present invention provides a method for forming a concrete block retaining wall that solves this problem.

[Means to solve the problem]

The present invention will now be described in detail with reference to the accompanying drawings.

A concrete block retaining wall in which a plurality of concrete block bodies are arranged side by side or stacked to form a retaining wall, and the left and right side walls 2 and 3 or the left and right side walls are connected to the front wall l of the retaining wall block body a. Fitting grooves 2°, 3', and 4' are vertically provided on the opposing inner surfaces of the side walls 2 and 3 and their intermediate walls 4 near the rear edges, and these retaining wall block bodies a are placed side by side on the foundation 5, and the Fit the closing plate 6 between the fitting grooves 2'' and 3° or between the fitting grooves 2'' and 4° and the fitting grooves 3'' and 4°, and Concrete 8 is poured into a gap 7 formed by side walls 2 and 3, an intermediate wall 4 therebetween, and a blocking plate 6, and the blocking plate 6 is removed or left as is to form a retaining wall. This relates to a load forming method for block retaining walls.

[Effect]

A foundation 5 is made by a conventional method, and retaining wall block bodies a are placed on it at predetermined positions.

Next, the closing plate 6 is fitted between the fitting grooves 2° and 3°, or between the fitting grooves 2° and 4°, and between the fitting grooves 3° and 4°, respectively.

Concrete 8 is placed inside this closing plate 6.

〔Example〕

The retaining wall block a in the drawing shows a case in which a bolt-and-nut system is adopted as the means 15 for connecting adjacent side walls 2 and 3.

Further, as a means for fixing to the closing plate 6, the abutting step portion 9
The figure shows a case in which a device is provided to prevent it from falling.

The drawing shows a case in which multiple fitting grooves 2°, 3°, and 4° are arranged in parallel, and by selecting the fitting position, the size of the gap 7 can be varied and the added weight can also be varied. There is.

4 and 5 illustrate the case where reinforcing beams 10 are installed at the lower rear edges of the left and right side walls 2 and 3 and the intermediate wall 4, but -
In the case of stacking, the base plate 11 may be formed by closing the entire bottom.

During construction, the closing plate 6 may be removed after concrete pouring, and the removed side may be the front.

Moreover, the front shape of the retaining wall block body a is square.

Various shapes are used, such as rectangular and other shapes, flat ones, uneven ones, patterns, and ones with side grooves.

The blocking plate 6 may be made of wood or strong iron, such as a control panel or template.

In the figure, reference numeral 12 is a pouring connection window, 13 is a recess for front and rear sliding up,
Reference numeral 14 indicates a drain hole, and 14° indicates a semicircular concave portion thereof, which assists the coupling means 15.

〔Effect of the invention〕

Since the present invention is constructed as described above, the retaining wall block body a is produced in a factory, transported to the construction site, placed side by side at a predetermined position, and then the back side of the retaining wall block body a is closed with a closing plate, and the inner side of the retaining wall block body a is closed. Because concrete is poured, very heavy retaining wall blocks will be installed.

In this case, even if the retaining wall block a is large, it becomes a light block by subtracting the weight of the concrete that will be poured later from the original weight of the block, making it easier to handle and less likely to be bumped during construction. It is easier to install it in a fixed position.

On the other hand, adding weight can be done simply by pouring concrete, making the work extremely easy.

This is a concrete retaining wall formation method that exhibits excellent practicality when constructing large retaining walls.
