Prefabricated retaining wall block}

The present invention relates to a prefabricated retaining wall block, and more specifically, to a prefabricated retaining wall block that is provided in the shape of a prefabricated block and forms an insulating layer inside to improve the convenience of work and prevent the risk of fire.

In general, formwork is a structure temporarily installed to make a concrete structure into a predetermined shape and size. Plywood for concrete formwork is mainly used, but depending on the construction, hard fiberboard, synthetic resin, aluminum panel, and steel plate are also used.

However, the formwork was installed simply to shape the concrete structure, and there was the hassle of dismantling and organizing it once the concrete was completed.

Therefore, there is a need for a form that can function as a formwork and at the same time be formed as a single piece and serve as a plate.

In addition, the outer wall 117 may be in the form of attaching a pattern mold to an existing form so as to have an embossed portion 117a and an intaglio portion 117b.

Figure 7 is a cross-sectional view of the body of a prefabricated retaining wall block according to an embodiment of the present invention. At this time, the bodies 110, 120, and 130 may represent the first body 110 to the third body 130.

Referring to Figure 7, the body (110, 120, 130) may include an inner skin layer (110a, 120a, 130a) and an outer skin layer (110b, 120b, 130b).

The inner skin layers 110a, 120a, and 130a may be made of carbon fiber, glass fiber, and/or metal fiber. Because of this, the inner skin layers 110a, 120a, and 130a may have low thermal conductivity. For example, the inner skin layers 110a, 120a, and 130a may be provided by mixing at least one or two of carbon fiber, glass fiber, and metal fiber. As another example, the inner skin layers 110a, 120a, and 130a may be comprised solely of carbon fiber, glass fiber, and metal fiber. As another example, the inner skin layers 110a, 120a, and 130a may be provided by overlapping at least one or two carbon fibers, glass fibers, and metal fibers. Additionally, the carbon fiber may be cotton carbon fiber. At this time, cotton carbon fiber can be manufactured by mixing decane compounds (e.g., octadecane, tetrodecane, nonadecane, hexadecane, etc.), which are latent heat substances, with heat-generating paint, dipping or spraying, and pressing. Moreover, cotton carbon fiber can have a heating effect due to its latent heat material properties.

For this reason, the prefabricated retaining wall block according to an embodiment of the present invention is provided with an inner layer (110a, 120a, 130a) composed of cotton carbon fiber and/or glass fiber, thereby improving insulation and heat generation functions to prevent fire and perform construction in winter. Because this is possible, stability and winter constructability can be secured.

The outer skin layers 110b, 120b, and 130b may be composed of one or two or three types of silica powder, colored stone powder, unsaturated polyester resin, epoxy resin, vinyl ester resin, and acrylic resin.

Hereinafter, the assembly sequence of the prefabricated retaining wall block 100 according to an embodiment of the present invention will be described.

First, the first body 110 is installed at a set position for retaining wall construction.

At this time, the protrusions 111 and 112 of the first body 110 are coupled to align with the grooves 113, 114, 123, 124, 133, and 134. Here, in order to combine the first body 110 by a set construction length, a plurality of first bodies 110 may be combined in one direction.

At this time, the connecting member 150 is coupled between the first bodies 110 facing each other. The connecting member 150 may be installed to connect the opposing first bodies 110 to each other whenever each first body 110 is installed.

Next, when the assembly direction is changed, one end of the opposing second bodies 120 are coupled to the opposing first bodies 110, respectively. For this reason, the prefabricated retaining wall block 100 according to an embodiment of the present invention is provided with bodies 110, 120, and 130 facing each other, so that double-sided insulation is possible, thereby solving problems affecting the internal structure due to environmental nutrients.

At this time, one end of each of the opposing first bodies 110 is coupled to the other end of each of the vertically opposing second bodies 120. Next, as described above, the first body 110 is extended and installed.

Because of this, the first body 110 and the second body 120 are extended and installed according to the set standards of the retaining wall as described above. That is, the first body 110 and the second body 120 are extended and installed to match the construction section.

Meanwhile, when the assembly of the first body and the second body according to the construction section is completed, the third body 130 is coupled to the last installed first body 110 or the second body 120. At this time, the prefabricated retaining wall block has a closed space formed by the first body, the second body, and the third body.

In this way, when the assembly of the first floor is completed, the above-described series of processes are repeated to stack and install the body (110, 120, 130) combination as a multi-stage prefabricated retaining wall block (100).

Next, the reinforcing material 140 is inserted into the body assembly of the multi-stage prefabricated retaining wall block 100. Here, the reinforcing material 140 may be installed and then inserted in stages or in plural stages depending on its length.

Finally, the prefabricated retaining wall block 100 is cured by pouring mortar 160 into the sealed space formed between the bodies 110, 120, and 130.

As a result, the prefabricated retaining wall block 100 can form a retaining wall in which the first to third bodies 110 to 130, the connecting member 150, and the mortar 160 facing each other are integrated.

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiment presented in the present specification, and those skilled in the art who understand the spirit of the present invention can add components within the scope of the same spirit. , other embodiments can be easily proposed by change, deletion, addition, etc., but this will also be said to be within the scope of the present invention.
