[ Example 1 ]: Composite beam Deck module

3A and 3B are front views of a horizontal frame panel and a vertical frame panel constituting a deck module according to the present invention, FIG. 3B is a moment diagram of the horizontal frame panel of FIG. 3B, 4 is a perspective view of a deck module according to the present invention by assembling the horizontal frame panel and the vertical frame panel of Fig.

Referring to these drawings, a deck module 11 according to the present invention is a long, thin, high-strength plate-like structure body, and is formed along one side of a plate-shaped body 100, At least one horizontal frame panel (10a) on which a plurality of horizontal frame panels (100a) are formed; The frame body 10a has a plate-like structure similar to the horizontal frame panel 10a and has a relatively short length as compared with the horizontal frame panel 10a. The frame body 10a is inserted into the assembly groove 100a of the horizontal frame panel 10a, And at least one vertical frame panel 10b installed so as to intersect the vertical frame panel 10a.

At this time, an escape groove 100c is formed in a region to receive compressive force with respect to the stress neutral plane of the body of the horizontal frame panel 10a.

That is, in the horizontal frame panel 10a, when the composite structure is formed, the area of the body 100 to be subjected to the compressive force with respect to the stress neutral plane during the vertical load operation in the composite structure is previously stored in the escape grooves 100c Is formed.

The escape grooves 100c are formed at both the left and right ends of the body 100 of the transverse frame panel 10a except for the central portion and the central portion. The escape grooves formed at the central portion and the escape grooves formed at the left and right ends, Are formed on the opposite sides with respect to the neutral plane.

This is based on the mechanical principle and takes into account the directionality of the moment which is caught by the center portion and both ends of the composite structure due to the vertical load applied to the composite structure in the state where the composite structure is formed.

Unlike the present embodiment, however, the escape grooves 100c may be formed only in the central portion of the body 100 of the horizontal frame panel 10a.

A plurality of assembly grooves 100a formed in the horizontal frame panel 10a and the vertical frame panel 10b are formed along the longitudinal direction of the plate so that the intersections between the two frame panels can be adjusted. In order to increase the bonding force between the frame panels 10a and 10b and the concrete 300 placed in the body region where the assembly grooves 100a of the frame panel 10a and the vertical frame panel 10b are not formed, Holes 100b are formed.

At this time, the size and shape of the through hole 100b can be various forms other than those shown in the figure.

Specifically, among the frame panels installed horizontally or vertically, the frame panel in the direction in which the frame panels are arranged is erected so that the entrance of the assembly groove 100a faces upward, and is later disposed in the direction intersecting the frame panel Is assembled so that the entrance of the assembly groove 100a faces downward. That is, the assembly groove 100a of one frame panel unit faces upward, and the assembly groove 100a of the other unit faces downward and is fitted into the assembly groove 100a. have.

In the present embodiment, the horizontal frame panels 10a are arranged so that the entrance of the assembly groove 100a faces upward, the vertical frame panels 10b are arranged with the entrance of the assembly groove 100a facing downward, And the assembling grooves of the vertical frame panels 10a and 10b are assembled to meet with each other, thereby forming a stable lattice structure.

In this embodiment, in order to improve the bonding force between the deck module and the concrete 300 to be combined with each other and to reduce the material, the through hole 100b is formed on the surface of the horizontal frame panel 10a and the vertical frame panel 10b constituting the deck module. However, the structure for improving the bonding force with concrete is not limited to this.

That is, in order to enhance the shear composite force with the concrete to be laid, it is also possible to provide a shear connection member (not shown), which is a projected structure together with the through hole 100b, on the surface of each frame panel. Only the shear connector may be provided instead of the sheath connector 100b.

It is also possible to increase the bonding strength between the horizontal frame panel 10a and the vertical frame panel 10b on the respective sides of the frame 300 with a plurality of unevenness or roughened surface roughness.

The composite beam-producing deck module 11 of the present invention having the above-described structure is assembled in such a manner that the assembly grooves of one frame panel unit are directed upward while the assembling grooves of the other units face downward So that it can be modularized without a separate welding operation.

That is, the deck module 11 of the present invention facilitates adjustment of the assembly interval between members due to the design due to the fine fitting grooves 100a at regular intervals, and reduces the work error through modularization of the members, .

Also, since the deck module 11 is factory-manufactured and provided to the site, it is possible to form a composite beam by pouring concrete and curing in the field.

In the case of FIG. 10, it is assumed that the deck module is not shown because it is substantially encapsulated in the concrete but is shown as a solid line for the sake of understanding.

Referring to these drawings, the composite beam 111a of the present embodiment adopts a deck module 11a of a modified structure different from that of the deck module 11 of the structure shown in the above-mentioned [second embodiment].

However, The deck module 11b is completed by disposing the assembly of the horizontal frame panel 10a and the vertical frame panel 10b having the U-shaped cross-section 400 on the inner side of the U-shaped deck plate 200, It is needless to say that the concrete 300 may be poured and cured inside the deck plate 200.

The construction process of the composite beam 111b according to the present embodiment having the above-described structure can also be divided into three as in the above-described [Embodiment 2] or [Embodiment 3] Except for being laid, the construction will proceed on the same principle, so detailed explanation will be omitted.

The composite beam 111b of the present embodiment manufactured and constructed as described above has the following advantages.

The composite beam 111b of the present embodiment can meet the required strength more effectively as the concrete is placed on the frame panel assembly in a state in which the reinforcing bar 400 is laid, so that the improved structural performance can be expected.

Accordingly, it is possible to reduce the deflection due to the construction load, minimize the necessity of the tilting, and reduce the installation cost and workload by reducing the related costs and air.

On the other hand, in each of the above-described embodiments, it is assumed that the intersecting high strength frame panel assembly has a frame panel installed only in the vertical direction with respect to the plurality of frame panels 10a installed in the horizontal direction, The number of frame panels in the vertical direction is preferably larger than the number of frame panels in the horizontal direction, and the interval of the frame panels 10b arranged in the vertical direction is But they may be set differently from each other.

Since the length of each frame panel and the distance between the mounting grooves 100a can be changed according to the design content, there is no particular limitation, and the depth of the mounting groove 100a is not particularly limited.

[ Example 5 ]: For composite slabs Deck module  The composite slab

16 is a perspective view of a deck module using a frame panel according to the present invention, FIG. 17 is a perspective view of a composite slab using the deck module of FIG. 16, and FIG. 18 is a flowchart to be.

Referring to these figures, the deck module for a composite slab according to the present invention comprises a plate body 100, at least one lateral At least one vertical frame panel 10b assembled to an assembly groove 100a of the horizontal frame panel 10a and installed so as to cross the horizontal frame panel 10a, And a flat plate type deck plate 200a for supporting the vertical frame panels 10a and 10b from below.

At this time, the horizontal frame panel 10a and the vertical frame panel 10b are basically the same shape, and the assembly groove 100a formed in the horizontal frame panel 10a and the vertical frame panel 10b, respectively, A plurality of frame panels 10a and 10b are formed along the longitudinal direction of the plate so that the intersecting positions of the frame panels can be adjusted, and the assembling grooves of the panels 10a and 10b are formed in directions opposite to each other in consideration of assembling performance.

Further, the positions of the mounting grooves of the panels 10a and 10b can be adjusted in consideration of the assemblability.

In order to increase the bonding force between the frame panels 10a and 10b and the concrete 300 placed in the body region where the assembly grooves 100a of the horizontal frame panel 10a and the vertical frame panel 10b are not formed, A plurality of through holes 100b are formed.

On the other hand, in the body 100 of the horizontal frame panel 10a and the vertical frame panel 10b, in a state in which the composite structure is constituted, a region to be subjected to the compressive force with respect to the stress neutral plane at the time of vertical load action, Is formed.

The escape grooves 100c are formed at the central portion of the body 100 and at both the left and right ends of the body 100. The escape grooves formed at the center of the body and the escape grooves formed at both ends of the body 100 are formed on opposite sides do.

Specifically, in the horizontal and vertical frame panels 10a and 10b, the escape grooves 100c at the central portion of the body 100 are formed on the upper side with respect to the neutral plane, As shown in Fig.

That is, in this embodiment, the horizontal frame panel 10a and the vertical frame panel 10b are basically of the same type (except for the direction of forming the assembly groove), unlike the above-described [Embodiment 1] - [Embodiment 4] (I.e., a synthetic concrete floor) by cross-installing in a transverse direction and a longitudinal direction.

The process of fabricating the composite slab using the frame panel and the deck module thus constructed is as follows.

At least two or more frame panels prepared are inserted and assembled into the assembly groove so as to intersect with each other in the horizontal and vertical directions.

Then, the frame panel assembly disposed horizontally and vertically is fixed on the plate-type deck plate 200a to complete the manufacture of the deck module 11c.

Thereafter, the concrete 300 is placed and cured on the deck plate 200a so that the frame panel assembly disposed in the horizontal and vertical directions of the deck module 11c is sealed.

The construction process of the composite slab 1111 manufactured by the above process can be divided into the following four cases according to which of the above manufacturing processes is carried out at the factory.

First, the entire composite slab 1111 including the deck module 11c is prefabricated in advance, and the manufactured composite slab 1111 can be transported to the construction site and installed in place.

Secondly, the deck module 11c is prefabricated in advance, and the concrete pouring and curing 300 is performed in the field after the deck module 11c is transported to the field.

Third, a frame panel assembly is prefabricated and transported to the site, then a frame panel assembly is placed on the flat deck plate 200a provided on the site, and then the concrete 300 is placed and cured .

Fourth, the entire processes such as assembling between the frame panels 10a and 10b and the process of fabricating the deck module 11c, placing the concrete 300, and curing may all be performed immediately on site. In this case, the production process is the construction process.

After completion of the construction of the composite slab 1111, the plate-type deck plate 200a constituting the composite slab 1111 is left as it is as a part of the composite slab after the concrete 300 is laid and cured .

When the deck plate 200a supporting the frame panel assembly 11c assembled in the transverse direction and the longitudinal direction is used by using the plywood made of wood, after the curing of the concrete is completed after the concrete 300 is poured, Can be removed.

The composite slab 1111 of the present invention manufactured and constructed as described above has the following advantages.

First, the high-strength steel plate unit is assembled at the calculated intervals according to a given load condition, the flow of the concrete is smoothly performed when the concrete is poured through the through hole 100b, and the adhesion strength of the concrete 300 can be increased.

 In addition, the conventional deck plate is limited to a unidirectional slab system. When the load is transmitted in one direction, the deck due to the applied load may occur largely. However, the composite deck floor system according to the present invention is one- ) And a two-directional slab system can be realized, which makes it possible to implement a system advantageous for both lateral and longitudinal deflection control.

In addition, since the use of the high-strength frame panel and the lattice of the existing composite deck floor system can achieve a greatly improved flexural performance and a reduction in deflection due to the large reinforced area, the long span slab Which is more advantageous in implementation.

Particularly, the composite slab 1111 of the present invention is applied to a high-strength non-welded fixed type frame panel capable of achieving a long span and a low floor height while achieving an optimum shape capable of reducing material, thereby reducing the construction error It is possible to secure a high quality of construction through the installation, and it is possible to shorten the cost and the air related to the permanent facility by reducing the installation facility and workload. In other words, the horizontal and vertical frame panels 10a and 10b constituting the composite slab 1111 of the present invention, through mechanical consideration of the vertical load received in the state in which the composite structure is formed, By forming the groove 100c, the material can be saved without loss of resistance against bending and shearing failure.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them.

That is, in the present invention, the length of the horizontal frame panel and / or the vertical frame panel, the forming direction and the forming position of the mounting groove formed in each panel, the depth of the mounting groove, Of course, it can be varied.

Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.

The present invention can reduce the construction error and the quality of the construction quality due to the improved structural performance and excellent workability when the composite concrete structure is constructed through the modularization of the optimum type high strength member based on the mechanical principle, The construction cost can be reduced through shortening of the air.

Therefore, the present invention can be effectively applied to the construction of beams and slabs of large-sized and high-rise buildings such as large-scale discount stores, runners and the like, and the modularization of members can be effectively utilized for remodeling work, .
