Abstract

PURPOSE: A lagging equipment by assembling the thin plate steel material is provided to improve the safety and use for a long time while the lagging equipment is reusable. CONSTITUTION: In the lagging equipment by assembling the thin plate steel material, three thin plate moulding member(1) make a triangle and are fixed by bolt and then connected to the ground by screw anchor bolt. The connection member is installed in the inside of the triangle by press, so that the member which is placed in the vertex is not pushed by earth pressure.

Description

Thin Steel Prefabricated Earth Facilities {.}

The present invention relates to the structure of the earth plate. More specifically, the weight is significantly reduced while the strength is improved, thereby increasing the safety at the construction site, reusing the soil for a long time, and making a complete product in the factory and assembling it on site. It will reduce logistics cost and construction cost and will keep the site environment clean.

Conventionally, the shaft is made of stone and woven with wire to prevent it from flowing down. Recently, it was used as cement or welded steel, but the flatness is heavy and many construction difficulties arise. In order to solve the advantages, the present invention can be completely combined by using a roll-formed steel sheet, and also plays a role of semi-permanently blocking the flow of soil by preventing loosening in a simple manner after the fastening.

In particular, the use of roll-formed steel plate used a method of light weight and improved strength. In order to facilitate on-site construction, the site is carried out by pressing holes through the intersecting parts by press to carry out the on-site construction. This makes it possible to contribute greatly to construction cost reduction.

Accordingly, the present invention is to compensate for the above-mentioned shortcomings, and the weight is remarkably reduced, the strength is improved, and the safety at the construction site is increased. Provide the structure of

Explanation of Signs of Important Parts of Drawings

(1) thin plate molding material

(2) connecting molding materials

(3) connection bolt

(4) fixed files

In order to achieve this purpose, the present invention maximizes the fixed strength by arranging the roll molding material (1) in the same shape and length in a triangle as shown in Fig. 1 and connecting them with bolts (3) as shown in Fig. 2. In addition, the fixing part with the ground has a structure to fix the connection with the ground simply and completely by using the screw anchor bolt as shown in Fig. 3 (4). This prevents the triangular vertex member from being pushed out by earth pressure. In addition, since the partial shape is triangular, continuous connection is possible so that the entire incision can be covered.
