Remodeling structure and remodeling method {REMODELING STRUCTURE AND CONSTRUCTION METHOD THEREOF}

The present invention relates to the field of construction, and more particularly, to a remodeling method for buildings.

The remodeling of residential spaces is the remodeling of limited residential spaces in order to secure efficient spaces and convenient living routes. The focus is on creating a space for the convenience of members with a new design that can meet the changed needs of living culture.

It is also used as a financial means to preserve real estate value. There are two types of residential space remodeling: single-family houses and multi-family houses.

The remodeling of commercial spaces is mainly the renovation of commercial buildings, such as old and old rental buildings and retail and retail buildings, to suit the modern sense.

It is used as a re-technological means to maximize the effect of the building by remodeling it with new design and building finishing materials. Especially, the construction cost is much lower than the new building because it is constructed without touching the skeleton of the building at all.

Recently, it has also attracted attention as a reinforcement structure for earthquakes.

Basically, the remodeling structure is required to make full use of structural materials such as columns and beams of the existing building so that the structure has greater overall strength and structural stability.

However, the conventional remodeling structure is based on the premise of dismantling a part of an existing building such as a masonry, which is expensive for dismantling and waste disposal, and causes harmful stress on the columns and beams of the existing building. In many cases, problems such as harming the overall structural stability by remodeling have been raised.

The present invention is derived to solve the above problems, it is possible to remodel without removing the existing building to reduce the cost of dismantling and waste disposal, harmful to the columns, beams of the existing building The purpose of the present invention is to propose a remodeling structure and a remodeling method that can minimize the occurrence of stress and increase structural stability.

The present invention provides a remodeling method using the remodeling structure, the method comprising: forming an anchor insertion hole (11) on the outer surface of the column (10) and the upper and lower beams (20); Installing an anchor (30) in the anchor insertion hole (11) and injecting a binder; Installing the PC panel (100) on both side pillars (10) and upper and lower beams (20) such that the anchor (30) is coupled to the anchor coupling hole (110) of the PC panel (100); Injecting a binder into the anchor coupling hole (110); Installing adjacent PC panels (100a) having the same structure as the PC panels (100) in the adjacent areas of the pillars (10) and the upper and lower beams (20) in the same manner; And filling the grout in the space between the PC panel 100 and the adjacent PC panel 100a to form the outer grouting charging unit 140.

The present invention enables remodeling without dismantling existing buildings, thereby reducing the cost of dismantling and waste disposal, minimizing the occurrence of harmful stresses on columns and beams of existing buildings, and enhancing structural stability. Make sure

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

As shown in Figure 1 below, the remodeling structure according to the present invention basically relates to the remodeling structure for reinforcing the two pillars 10 and the upper and lower beams 20 coupled to the existing building, both pillars 10 And an anchor 30 installed to protrude outward to the anchor insertion hole 11 formed on the outer surface of the upper and lower beams 20. Anchor coupling hole 110 is formed so that the anchor 30 is coupled, the PC panel 100 is installed on both sides of the column 10 and the upper and lower beams 20 and supported by the anchor 30; It is configured to include.

That is, by installing the anchor 30 on the outer side of both pillars 10 and the upper and lower beams 20 coupled to the existing building, thereby taking a structure that the PC panel 100 is supported on the outside, Rigidity is achieved by integrating the two pillars 10 and the upper and lower beams 20 coupled thereto without removing any existing masonry in the inner region of the two pillars 10 and the upper and lower beams 20 coupled thereto. Make it possible to achieve large reinforcement structures.

This has the effect of changing the support structure by the pillars 10 and beams 20 of the existing building to a support structure by a more robust bearing wall, so as to have a very large rigidity against lateral loads (eg, earthquake loads) during external forces. do.

Since the present invention does not need to dismantle the existing building, it is possible to reduce the cost of dismantling and disposal of the waste, while minimizing the generation of harmful stress on the pillars and beams of the existing building, thereby improving structural stability. To help.

In some cases, there may be a gap between the outer surface of the wall 40 and the inner surface of the PC panel 100, such as a masonry of an existing building installed in the inner regions of the two pillars 10 and the upper and lower beams 20, By filling the grout, it is preferable to form the inner grouting filling part 120 (FIG. 3).

When the windows 12 of the existing building are formed in the inner regions of the two pillars 10 and the upper and lower beams 20, the through-holes 130 are formed in the core of the PC panel 100 so as to penetrate the windows 12. ), Effective reinforcement can be achieved without compromising the function of existing buildings.

The PC panel 100 is preferably formed over the entire outer area of the pillar 10 and the beam 20 of the existing building for effective reinforcement (FIG. 6).

This can be implemented by a method in which adjacent PC panels 100a having the same structure as the PC panel 100 are installed in the same manner in the adjacent areas of the pillars 10 and the upper and lower beams 20, in this case, the PC panels. It is more preferable for the integration of the structure to form the outer grouting filling section 140 by filling the grout in the space between the 100 and the adjacent PC panel 100a (FIG. 6).

Hereinafter, a remodeling method using a remodeling structure according to the present invention will be described.

Anchor insertion holes 11 are formed on the outer surfaces of both pillars 10 and the upper and lower beams 20, and anchors 30 are installed in the anchor insertion holes 11, and then a binder such as epoxy is injected. Ensure a firm fixation (Figures 3, 4).

The PC panel 100 is installed on both pillars 10 and the upper and lower beams 20 so that the anchor 30 is coupled to the anchor coupling hole 110 of the PC panel 100 (FIGS. 1 and 2).

When the window 12 exists in an existing building, the window through hole 130 of the PC panel 100 is installed to penetrate with each other.

A binder such as epoxy is injected into the anchor coupling hole 110 of the PC panel 100 so that the anchor 30 and the PC panel 100 are firmly coupled to each other.

The inner grouting filling part 120 is formed by filling grout between the outer surface of the wall 40 of the existing building and the inner surface of the PC panel 100 installed in the inner regions of both pillars 10 and the upper and lower beams 20.

Adjacent PC panels 100a having the same structure as the upper PC panels 100 are also installed in the adjacent areas of the two pillars 10 and the upper and lower beams 20 in the same manner.

The grout is filled in the space between the PC panel 100 and the adjacent PC panel 100a to form the outer grouting charging part 140 (FIG. 6).

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.
