In order to solve the problem of waterproofing due to the formation of the elongated hole 311, a waterproof layer 200 is formed on the outer surface of the inner assembly 100 (an inner space of the inner and outer assemblies) instead of the outer surface of the outer assembly 300 .

Therefore, when it is necessary to construct a plurality of corrugated steel sheets by overlapping with each other due to a large design load, there is an effect that the structure can be stably and efficiently installed.

The above structure is also applicable to a structure (sandwich structure) in which the corrugation of the inner corrugated steel plate 110 forming the inner assembly 100 is engaged with the corrugation of the outer corrugated steel plate 310 forming the outer assembly 300 The structure of the upper waterproofing layer 200 can be applied to a structure in which the inner surface of the corrugated steel sheet 110 is joined to the corrugated surface of the corrugated steel sheet 310 (FIG. 2) It is more effective.

In this case, the method of constructing the arch structure according to the present invention is performed by the following process.

The inner corrugated steel plate 110 is formed by assembling a plurality of the inner corrugated plates 100 of the inner corrugated steel plate 110 and the adjacent inner corrugated steel plates 110a adjacent thereto The bolt 410 is commonly connected to the circular coupling hole 111a and the head portion 411 of the bolt 410 is directed toward the inside and the tail portion 412 of the bolt 410 is engaged with the circular coupling hole 111, As shown in FIG.

The inner corrugated steel plate 110 and the adjacent corrugated steel plate 110a are fixed to each other to secure a gap for the waterproof layer 200 and to prevent the bolt 410 from being separated from the tail portion of the bolt 410 412).

That is, the inner corrugated steel plate 110 and the adjacent inner corrugated steel plate 110a are combined by the combined structure of the bolt 410 and the spacer 420. [

The waterproof layer 200 is formed by applying a waterproof material to the outer surface of the inner assembly 100. [

The outer corrugated steel plate 310 is installed so as to cover the outer surface of the waterproof layer 200 by assembling a plurality of corrugated steel plates 310 to form the outer assembly 300, The end of the tail portion 412 of the bolt 410 is exposed and the nut 430 is screwed to the end portion of the tail portion 412 of the bolt 410.

That is, the inner corrugated steel plate 110, the adjacent inner corrugated steel plate 110a, and the outer corrugated steel plate 310 are coupled by the coupling structure of the bolt 410, the spacer 420 and the nut 430.

This is advantageous in that a mutual coupling of a plurality of internal corrugated steel sheets and a coupling with an external corrugated steel sheet are made by a single fastening structure at one point, so that the number of perforations can be minimized and an excellent waterproof structure can be obtained.

Second, the fastening member 400 is coupled to the circular coupling hole 111 of the internal corrugated steel plate 110, and the head portion 411 is directed toward the inside and the tail portion 412 is connected to the circular coupling hole 111 A bolt 410 installed to protrude outwardly; A spacer 420 screwed to the center of the tail portion 412 of the bolt 410 so as to secure a space for the waterproof layer 200 and to prevent the bolt 410 from coming off; Shaped engaging hole 311 of the external corrugated steel plate 310 and the elongated concave engaging hole 311 of the adjacent external corrugated steel plate 310a provided adjacent to the elongated concave engaging hole 311 of the external corrugated steel plate 310, And a nut 430 screwed to the end of the tail portion 412 of the exposed bolt 410 (FIG. 4).

In this case, the method of constructing the arch structure according to the present invention is performed by the following process.

The inner corrugated steel plate 110 is assembled by assembling a plurality of bolts 410 to the circular coupling hole 111 of the inner corrugated steel plate 110 and the bolts 410 And the tail portion 412 of the bolt 410 protrudes outward through the circular coupling hole 111. In this case,

The spacer 420 is screwed to the central portion of the tail portion 412 of the bolt 410 so as to secure the space for the waterproof layer 200 and to prevent the bolt 410 from coming off.

That is, the tail portion 412 of the bolt 410 is exposed to the outside in order to engage with the external corrugated steel sheet.

The waterproof layer 200 is formed by applying a waterproof material to the outer surface of the inner assembly 100.

The outer corrugated steel plate 310 is formed so as to cover the outer surface of the waterproof layer 200 by a plurality of assemblies to form the outer assembly 300. The outer corrugated steel plate 310 has a rectangular- And the tail portion 412 of the bolt 410 is commonly connected to the long hole type coupling hole 131a of the adjacent external corrugated steel plate 310a provided by the long hole type coupling hole 311, The nut 430 is screwed to an end portion of the tail portion 412 of the tubular body 410.

Also in this embodiment, since the mutual coupling of the inner corrugated steel plate and the plurality of outer corrugated steel plates is made by one fastening structure at one point, there is an advantage that the waterproof structure can be obtained by minimizing the number of perforations .

The spacer 420 of the fastening member 400 has a role of mutually fixing the internal corrugated steel plate 110 and the adjacent internal corrugated steel plate 110a and securing an interval for the waterproof layer 200, 410, and the like.

In order to perform this role more efficiently, the spacer 420 includes a body portion 421 of a polygonal plate structure; A screw portion 423 formed in the hollow 422 of the body portion 421 to be screwed with the bolt 410; And an elastic support portion 424 extending outward from an edge of the body portion 421 (Figs. 7 and 8).

In this case, the body portion 421 of the polygonal plate structure is structured so as to protrude to some extent outward without being completely recessed in the circular coupling hole 111 of the inner corrugated steel plate 110 due to the polygonal structure and the elastic supporting portion 424 It is possible to more reliably perform the role of securing the interval for the waterproof layer 200. [

When the trunk portion 421 and the elastic support portion 424 have a unitary bending structure, the above-described effect can be obtained more stably.

The threaded portion 423 is formed by a plurality of pieces 420 protruding inwardly from the hollow 422 of the body portion 421 so as to be threadedly engaged with the bolt 410 even though the body 421 has a plate- And a plurality of the engraved portions 423a are preferably formed to have different protruded heights.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
