The present invention relates to a prefabricated building earth plate easy to adjust the width, and more particularly, to improve the earth plate installed in order to prevent the fall of the earth wall in the construction work such as digging work easier to install the earth plate than conventional earth plate The present invention relates to a prefabricated building earth plate that is easy to adjust its width to allow a wide span.

The land use of Korea is mainly concentrated in large cities, and due to the lack of available land, high-rise and high-density urban areas are accelerating. As the structure of underground structures increases due to the use of high-rise and densified lands, close construction with neighboring buildings is inevitable. It is a frequent occurrence, resulting in a number of social problems caused by a number of complaints and civil and criminal disputes, including property loss. Therefore, the selection of construction method and member for earth wall temporary construction work in underground excavation has emerged as a very important factor.

In general, in order to prevent the collapse or spillage of soil at the edge of the ground excavation part in the underground ground work of the building, or incision site in the civil engineering work, H-beams have a predetermined depth on the ground at regular intervals as shown in FIG. 1. After fixing with a roller, the earthen board construction is made of sandwiching the earth plate between the H-beams, generally the earth plate is made of wood or bent iron plate.

Accordingly, after the H-beams are put on the ground, the earth and sand are excavated to a predetermined depth, and the earth and sand plates are sandwiched between the H-beams to be stacked so that the surrounding soil is not introduced into the construction site.

At this time, the earth plate should have the flexural strength (compressive strength) that can support the earth pressure acting on the underground incision surface. If the flexural strength is insufficient compared with the earth pressure, shear failure of the earth plate will occur and the flange of H-beam Escape from and leads to the collapse of the soil.

Therefore, in order to achieve the purpose of the earth block, the earth plate should have both flexural strength and compressive and tensile strength that can cope with the earth pressure, and the H-beam serves as a support for supporting the earth plate from being pushed back.

However, since the flexural strength of the earth plate increases as the material thickness increases, and the specific gravity or density of the material increases, the volume or weight of the earth plate becomes large when the earth plate is applied to the earthquake construction that requires high earth pressure. There were only disadvantages. In addition, when the width of the earth plate is widened, the earth plate is bent due to the earth pressure.

And when the H-beam is installed to install the earth plate, the span is not constant. In the case of the wood earth plate, the span, which is the interval of the H beam, is measured one by one. It is inconvenient to install, excessive installation time and installation cost, and disassembly is almost impossible due to earth pressure.

In addition, although it must be dismantled and collected, it is difficult to be recycled due to uneven specifications, which are each cut and dismantled, so that it is usually buried as it is not dismantled. I'm concerned.

In the case of earthen boards made of steel or synthetic resins as well as wood earthen boards, they are usually manufactured in a constant size, so there is a problem in that the force between the H beams is embedded at regular intervals.

The present invention has been made in order to solve the problems as described above, it is possible to install the earth plate in spite of the gap between the non-uniform H-beams, it is possible to install the earth plate with a wide span by configuring the width of the earth plate can be adjusted widely There is a purpose to be. Therefore, there is no need to put a lot of H-beams, the purpose is to save time and money.

In addition, the purpose is to stably support the widened earth plate to prevent local twist, and to prevent the collapse of the local area.

And the upper and lower coupling of the earth plate is firmly fixed, there is an object to prevent the coupling force is weakened by the gap between the upper and lower earth plate.

In order to achieve the above object, the present invention has a central support part integrally formed at the center of two plate bodies, and expansion plate installation grooves are formed at both sides of the central support part, and a top and bottom coupling groove is formed at the top of the central support part. The upper and lower coupling protrusions are formed in the same shape on the lower surface of the branch, and one end of the fixing band is fixed to both sides of the plate body on one side, and grooves with hook bars are formed on both sides of the other plate body, and the hooks formed on the other end of the fixing band are hooked. A main body plate detachably fastened to the bar and having two anchor holes penetrating up and down in the central support unit; The spring is fixed to the two fixing plates, the bellows cover is installed around the spring, one fixing plate is bolted to the bottom of the expansion plate mounting groove, the other fixing plate is fixed to the bottom of the hollow part of the expansion plate Spring assembly; A hollow part having one side open is formed in the plate body inserted into the expansion plate installation groove of the main body plate, and a locking jaw is formed on both sides of the end portion having the open part of the hollow part, and guide grooves are formed at both sides of the plate body. An expansion plate to which the fixing cover is fixed to the other end by bolts so that the fixing cover portion is inserted into the H beam; One side is bent by the letter A to form a locking jaw, the locking jaw is inserted into the expansion plate installation groove of the body plate is fixed to the end of the plate with a bolt, the guide projection is formed on one side is inserted into the guide groove of the expansion plate of the expansion plate A guide plate for guiding the movement; Two branched anchors are integrally formed on the bottom surface of the coupling protrusion, the head is formed on the upper surface of the coupling protrusion, the coupling protrusion is inserted into the anchor hole of the width adjustment earth plate fixed to the ground; To provide a prefabricated building earth plate easy to adjust the width.
