The present invention proposes a remodeling structure and a remodeling method for minimizing the generation of harmful stresses on the columns and beams of existing buildings, thereby improving structural stability.

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

As shown in Figure 1 below, the present invention basically relates to a remodeling structure for reinforcing the two pillars (1) and the beam (2) coupled to the existing building, both sides installed on the inner side of the two pillars (1) Fixing member 10; An upper fixing member 20a installed on a bottom surface of the upper beam 2a among the beams 2 coupled to both pillars 1; A lower fixing member 20b installed on an upper surface of the lower beam 2b among the beams 2 coupled to both pillars 1; It characterized in that it comprises a; PC panel 200 is fixed by both side fixing member 10, the upper fixing member (20a) and the lower fixing member (20b).

That is, for the remodeling, the existing structure installed in the inner region of both pillars 1 and the beam 2 coupled to the existing building is removed, and the PC panel 200 described above is fixed to the fixing member 10 in the region. 20a, 20b) to be integrated to increase the rigidity and structural stability of the structure (Fig. 1,2).

In addition, when such a structure takes a configuration repeated in the vertical direction for all or part of the existing building (PC panel 200 for all areas between a plurality of beams from the top to the bottom of both pillars 1) When installed), as the PC panel 200 acts as a bearing wall (shear wall) will exhibit a very large strength and structural stability compared to the existing structure.

Such a structure has an advantage of maximizing the inherent strength possessed by these structural members without generating any harmful stress on the columns 1 and beams 2 of the existing building.

Both fixing members 10, the upper fixing member (20a) and the lower fixing member (20b) serves to fix and integrate the PC panel 200 with respect to the pillar (1) and beam (2) of the existing building, It is preferable to take the 'b' shaped structure 100 as shown in Figures 3 to 7 in terms of convenience of work and efficiency of the structure.

The 'b' shaped fixing member 100 is an existing building coupling portion 110 to be coupled to the surface (1) or beam (2) to the surface contact; It is configured to include; PC panel coupling portion 120 to be coupled to the PC panel 200.

Since the point of remodeling will be a very old service life of the existing building, it will be common for the columns 1 and beams 2 to be placed in a situation where they do not maintain a right angle to each other and cause a certain deformation. An end portion of the PC panel 200 installed between the 100a and the 100b may have some gap with the wall surface of the pillar 1.

In order to make it a tight structure by the filling of the mortar, the mortar injection hole 11 is formed between the upper end of the inner 'b'-shaped fixing member 100a coupled to both pillars 1 and the bottom of the upper beam 2a. By doing so, it is necessary to be able to inject mortar through it.

There may be a variety of ways to form the mortar injection hole 11, but as shown in Figure 4, the PC panel coupling portion 120 of the 'b' shaped fixing member 100 compared to the existing building coupling portion 110 When taking the structure formed so that the upper end is short, it is preferable in that the mortar injection hole 11 is naturally formed in the upper portion of the PC panel coupling portion 120.

The upper fixing member 20a or the lower fixing member 20b for fixing the upper and lower portions of the PC panel 200 may be installed over the entire area of the beam 2, but in this case, the center thereof is far from the pillar 1. Due to the structure will not have a different meaning and will only cumbersome work, such an upper fixing member 20a or lower fixing member 20b is preferably installed in the edge region of the beam (2) (Fig. 2) .

However, even in this case, it is preferable in terms of structural stability that the length of the upper fixing member 20a or the lower fixing member 20b is more than the width of the pillar 1.

Among the existing building coupling members 112 that couple the upper fixing member 20a or the lower fixing member 20b to the beam 2, the existing building coupling member installed closest to the pillar 1 is connected to the pillar 1. It is preferable in terms of increasing rigidity that the spacing is within 10 cm.

It is preferable that the coupling structure of the upper fixing member 20a, the lower fixing member 20b, and the PC panel 200 also has a welding coupling structure as in the case of the both fixing members 10 described above (Figs. 6 and 7).

Hereinafter, an embodiment of the remodeling method according to the present invention using the remodeling structure described above will be described.

The inner part of both columns 1 and the beam 2 coupled to the existing building is removed (FIGS. 8 and 9).

A coupling hole 3 is formed inside and outside of both pillars 1, the upper beam 2a and the lower beam 2b by a drill, and the inner 'b' shaped fixing member by the existing building coupling member 112. The existing building coupling portion 110 of 100a is coupled to the inner coupling hole 3 of both pillars 1, the upper beam 2a and the lower beam 2b (FIG. 10).

Mortar is injected through the mortar inlet 11 to fill the space between the PC panel 200 and the pillar 1, and the reinforcing plate 210 and the inner 'b' shaped fixing member 100a of the PC panel 200. And the PC panel coupling part 120 of the outer 'b' shaped fixing member 100b by main welding (FIG. 14).

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
