Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 4 and subsequent drawings, the ramen structures proposed in the present invention include a plurality of walls 400 spaced apart from each other; An arch portion (100) having both ends connected to an upper portion of the plurality of walls (400) and forming an arcuate structure; An upper plate part 200 formed by placing concrete on the upper part of the arch part 100 and the wall body 400; And a hollow portion 300 formed at both ends of an area between the arch portion 100 and the upper plate portion 200.

The reason why the hollow portion 300 is formed in the raymen structure is as follows.

Generally, the bending moment generated in the arcuate raymen structure is concentrated on the center and right corner portions 15 and 24 of the slab 11, and when the slabs 11 and 21 and the concrete of the wall 12 are simultaneously installed, An excessive bending moment is generated in the projections 15 and 24 (Figs.

Therefore, as shown in FIG. 2, in the conventional arched-type raymen structure, the cross sections of the right angles 15 and 24 are made larger than the center cross-section of the slab 11 to bear an excessive bending moment.

Therefore, in the present invention, when the wall body 400 is firstly installed, the arch portion 100 is assembled, and the upper plate portion 200 is poured, a bending moment is generated in the right corner portions 15 and 24 It is possible to maintain the cross section of the right corners 15 and 24 at the center cross section size.

In addition, for the purpose of reducing the dead load, a structure is shown in which hollow portions 300 are formed at both ends (FIG. 4).

As a result, compared with the conventional structure in which the concrete is entirely installed in the hollow 300, the concrete pouring area can be drastically reduced, thereby improving the efficiency, workability, and economy of the cross section.

Further, since the self weight is reduced through the hollow portion 300, the structural stability of the ramen structure can be further improved.

In addition, as shown in FIG. 4, the raymen structure of the present invention can be applied to a raymetal bridge and, as shown in FIG. 11, it can be applied to a box-type tunnel, which is advantageous in terms of applicability.

The present invention is characterized in that the arch portion 100 is formed in a structure in which a plurality of corrugated steel plates 110 are coupled to each other (Figs. 5 to 7).

The effect obtained through this structure is as follows.

First, a plurality of corrugated steel plates 110 serve as a deck plate for the upper plate 200 formed by placing concrete on the upper part.

With this structure, it is possible to effectively distribute the loads acting on the upper plate portion 200 by the plurality of corrugated steel plates 110, and to resist the bending moment, thereby securing the rigidity against deformation.

Therefore, it is possible to prevent the occurrence of buckling, thereby improving the structural stability of the ramen structure.

Secondly, the corrugated steel sheet 110 has an advantage that it can reduce the thickness of the cross section of the upper plate 200, and is easily installed in an assembled structure.

In addition, since the composite structure of the corrugated steel plate 110 and the upper plate 200 combined with concrete does not need to backfill the upper part of the upper plate 200, .

That is, in the case of a bridge using a corrugated steel plate in the past, a structural backfill should be made in the lateral direction of the bridge because there is a characteristic of an underground structure acting together with the surrounding ground.

However, according to the present invention, since the corrugated steel plate 110 and the upper plate 200 are integrated by concrete, there is no need to backfill the soil, and it is very easy to form a long bridge.

Therefore, there is an effect of improving workability and usability.

Fourth, at the time of pouring concrete for forming the upper plate 200, the corrugated steel plate 110 serves as a corrugation, so that it is not necessary to provide a separate corrugate.

Therefore, it has an advantage that the workability can be improved and the working time can be shortened.

The structure of the ramen structure of the present invention will be described in more detail as follows.

The hollow portion 300 of the present invention is preferably provided with a reinforcing member 310 to connect the arch portion 100 and the upper plate portion 200 (Figs. 4 and 9).

The installation structure of the reinforcing member 310 may be implemented in the following embodiments.

The reinforcing member 310 includes a pillar member 311 installed along the width direction of the bridge and a lightweight member 313 installed in the remaining space of the hollow portion 300 excluding the space in which the pillar member 311 is installed. (Fig. 4).

Second, the reinforcing member 310 may be installed in a structure including a plurality of partitions 312 provided at intervals along the longitudinal direction of the structure and a lightweight member 313 provided between the plurality of partitions 312 (Fig. 9).

The column member 311 and the partition wall 312 are formed by a formwork and are integrally formed with the top plate 200 when the concrete for forming the top plate unit 200 is poured.

Therefore, the column member 311 and the partition wall 312 effectively bear the load received from the upper portion, and at the same time, serve to integrate the arch portion 100 and the upper plate portion 200 integrally, thereby further improving the structural rigidity do.

In addition, instead of placing the concrete in the area of the hollow part 300, a structure in which a lightweight lightweight member 313 is provided so as to bear only the dead load (self weight) actually applied to the hollow part 300, It is possible to obtain an effect of improving the economical efficiency through an effective cross-sectional structure.

The lightweight member 313 may be any of the members capable of exhibiting the above functions, but it is more preferable in terms of function and economy to use the styrofoam 314. [

As described above, the arch portion 100 used in the ramen structure of the present invention is formed by a structure in which a plurality of corrugated steel plates 110 are coupled to each other.

More specifically, a structure in which a plurality of corrugated steel plates 110 are coupled to each other is implemented as follows (Figs. 5 and 6).

That is, one side of the left corrugated steel plate 110a and the other side of the right corrugated steel plate 110b of the plurality of corrugated steel plates 110 are formed by coupling with the bolts 2 and the nuts 3 in the vertical direction .

Here, the tail portion of the bolt 2 is set to face upward, and the tail portion of the bolt 2 is fastened by the cap 4 with the upper portion closed, and is fixed by welding.

A large number of bolts 2, nuts 3 and caps 4 are provided along the lateral direction and longitudinal direction of the bridge in order to engage the plurality of corrugated steel plates 110 and the tail portion of the bolt 2 100, so that the upper members also function as studs in the arch portion 100 (FIG. 7).

Therefore, the bolts 2 and the caps 4 protruding upward from the arch portion 100 provide an effect of enhancing the structural stability by increasing the bonding force to the concrete placed on the upper portion of the arch portion 100.

In addition, the waterproof member 5 is joined to the space between one side of the left corrugated steel plate 110a and the other side of the right corrugated steel plate 110b (Fig. 6).

The waterproofing member 5 is a member for airtightly holding the joint portion of the left corrugated steel plate 110a and the right corrugated steel plate 110b, and is preferably provided in a thin plate-like structure.

The waterproofing member 5 may be any member that exhibits the above functions, but it is preferable to use the gasket 6 from the functional and structural viewpoints.

The ramen structure of the present invention is characterized in that an engaging portion 120 is formed to engage both ends of the arch portion 100 and the upper portion of the wall body 400 (FIG. 8).

In order to mount both ends of the arch part 100 on the upper part of the wall 400, the upper part of the wall body 400 has to have a structure corresponding to both ends of the arch part 100, There is a problem that construction is very difficult.

Accordingly, in the present invention, the structure of the coupling part 120 is shown as follows, so that both ends of the arch part 100 can be stably coupled to the upper part of the wall body 400.

That is, an arch mounting groove is formed in the upper portion of the wall body 400 so that both ends of the arch portion 100 can be mounted on the upper portion of the wall body 400.

The engaging portion 120 is provided in the arch mounting groove and includes a channel 122 formed in a section corresponding to the end surface of the arch portion 100 and a channel 122 formed in a cross section corresponding to the cross section of the arch portion 100, And anchor bolts 121 for fastening the both ends of the arch part 100, which are mounted on the upper part of the body 100, to the upper part of the channel 122 and the wall 400.

It is very easy to form the channel 122 having a small cross sectional area in a structure corresponding to the cross section of the arch portion 100. It is also easy to install such a channel 122 on the upper portion of the wall 400. [

Therefore, it is relatively easy to fix both ends of the arch portion 100 to the upper portion of the wall 400 by using the channel 122, and it is possible to obtain an advantage of ensuring the accuracy of the operation.

In addition, since the arch part 100 and the wall body 400 are firmly connected to each other by the anchor bolts 121, the structure of the integral type frame structure can be more effectively realized, thereby maximizing the structural rigidity of the bridge.

Next, a method of constructing a rheme structure using the rheme structure of the present invention will be described.

First, a wall installation step is performed in which a plurality of walls 400 are installed so that the lower part is fixed on the ground.

4, a plurality of walls 420 may be installed at a distance from each other to form a bridge having a ramen structure.

In addition, as shown in FIG. 11, in order to form a box-shaped tunnel of a ramen structure, the wall 430 and the foundation may be integrally formed in a box-like structure.

Next, both ends of the arch portion 100 are coupled to the upper portions of the plurality of walls 400, respectively.

In the step of installing the arch, the end of the corrugated steel plate 110 is fixed to the upper part of the wall body 400 using the anchor bolts 121, and then a plurality of corrugated steel plates 110 joined to the upper part of the wall body 400 And the corrugated steel sheet 110 are sequentially joined to each other to form the arch portion 100.

As described above, in the corrugated steel plate joining step, a waterproofing member 5 is disposed in a space between one side of the left corrugated steel plate 110a and the other side of the right corrugated steel plate 110b among the plurality of corrugated steel plates 110 And the other side of the right corrugated steel plate 110b is coupled to the other side of the left corrugated steel plate 110a by the bolts 2 and the nuts 3 in the up and down direction, And a bolt joining step in which the upper portion is tightened by a cap 4 having a closed structure.

In order to realize a structure in which the hollow portion 300 is formed at both ends of the area between the arch portion 100 and the upper plate portion 200, a mold and a lightweight member are installed to form the mold and the lightweight member 313.

The steps of installing the mold and the lightweight member may be performed by the following processes in order to implement the structure of any one of the two embodiments described above.

First, a plurality of lightweight members 313 are disposed on the concrete pouring area inside the mold so as to form the pillar member 311 in the hollow part 300, spaced apart from each other along the width direction of the bridge (FIG.

Secondly, a plurality of lightweight members 313 are disposed on the concrete pouring area inside the mold so as to form the partition wall 312 in the hollow part 300 so as to be spaced apart from each other along the longitudinal direction of the bridge (FIG.

After the mold and the lightweight member 313 are installed in any one of the above two embodiments, the hollow portion and the upper plate portion forming the hollow portion 300 and the upper plate portion 200 by placing the concrete in the mold .

The ramen structure of the present invention can secure the structural rigidity by efficiently sharing the load received from the upper plate portion 200 by the corrugated steel plate 110 and thus providing the extended upper plate portion 200 extending from the wall 400 It can also be constructed as a structure.

In such a construction, it is preferable in terms of structural stability that the steel pipe pile 410 is coupled to the lower part of the wall body 400 and is embedded in the ground, and then the extended upper plate part 200 is installed .

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.
