Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a steel frame structure, a reinforced concrete structure, or a steel frame reinforced concrete structure.
The present invention relates to an outer wall structure for mounting a dry outer wall material (hereinafter, simply referred to as a wall material) on a wall foundation such as a structure, an RC structure, or an SRC structure.

[0002]

2. Description of the Related Art Generally, new construction, S construction, RC construction, S construction
In order to form the outer wall for RC construction, etc., there was no choice but to reinforce the existing outer wall in the RC construction and the SRC construction, to reinforce the existing outer wall, to remove the existing outer wall, and to rebuild it again as a new construction. .

[0003]

However, RC
It took a huge amount of money to demolish and rebuild the SRC and SRC structures, and it took a lot of days from the demolition to the completion. Further, in the old RC and SRC structures, cracking of concrete, exfoliation of concrete, and the like have been increasing in recent years due to alkali aggregate reaction (salt damage), and countermeasures against them are urgently desired.

[0004]

In order to eliminate such drawbacks, the present invention constructs a wall material having a male-female connecting structure on the left and right on a new or existing outer wall as a base. The structure consists of a long flat mounting base made of flat steel and a long fixed base with a Z-shaped cross section. Multiple mounting bases are arranged in a line on the wall base and fixed at fixed intervals. Then, a plurality of fixed bases are fixed on the mounting base so that one surface of the fixed base is orthogonal to each other, and the wall material is fixed on the other surface of the fixed base to the wall base by male and female connection and fixing with a fixing tool. It is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the outer wall structure according to the present invention will be described in detail below with reference to the drawings. FIGS. 1 and 2 show examples of horizontal stretching, and FIGS. 3 and 4 show vertical stretching. A is a mounting base, B is a fixed base, C is a wall material, α is a wall base, and β is a fixture. is there.

More specifically, the wall base α is made of a newly constructed frame or a renovated S structure (steel frame structure), RC structure (reinforced concrete structure), SRC structure (steel frame reinforced concrete structure), and the fixing tool β is self-supporting. It consists of drilling screws (tex, pan, flat, hex, etc.), bolts, nuts, washers, anchor bolts, etc., or welding.

The mounting base A is a mounting piece 1 as shown in FIG.
It is composed of a flat bar (flat steel) that is widely used.

The mounting piece 1 is a portion for mounting the mounting base A on the wall base α, and fixes the proper position to the wall base α by a fixing tool β such as an anchor bolt.
It also functions as a base to which a fixed base B described later is attached.

The fixed base B is a long steel material as shown in FIG. 6, has a Z-shaped cross section, and has a rising piece 4 formed between the fixed portions 2 and 3.

The fixed base B is attached by welding to the mounting piece 1 of the mounting base A attached to the wall base α so as to be orthogonal to each other, and also functions as a base for mounting a wall material C described later.

As shown in FIGS. 7A and 7B, the wall material C includes a core material C ₃ between a metal surface material C ₁ and a sheet-shaped back surface material C _2.
It is a horizontal or vertical wall material C that can be applied by a dry method and is made of a metal-based siding material formed by sandwiching or a ceramic-based siding material, an ALC plate, a ceramic plate, or the like.

More specifically, the wall member C has a male connecting portion 5 having an engaging groove 6 formed in a generally U-shaped cross section at one edge in the width direction and a mounting portion 7 protruding outward, and the other end. It has a long shape (about 2424 to 7272 mm) in which a female type connecting portion 8 having an insertion edge 9 having an edge protruding outward is formed.

The mounting portion 7 functions as a fixing portion when the wall material C is applied to the fixed base material B, and together with the connection of the male and female connecting portions 5 and 8, the wall material C is connected via the fixture β. Is applied to the fixed base B.

Next, a construction example of the outer wall structure according to the present invention will be briefly described. First, as shown in FIG. 1 and FIG.
It is assumed that a wall material C as shown in FIG. 7B is installed laterally on an existing outer wall made of RC structure to be repaired. Then, the mounting base A made of flat steel (thickness 3 mm × width 50 mm) is fixed on the wall base α at a pitch P ₂ (600 to 3000 mm or so) by a fixing tool β made of anchor bolts. Next, the thickness is 2.3 mm, and the lengths of the fixing portions 2 and 3 are 30 m.
m long Z-shaped steel fixed base B pitch P
₁ (450 to 600 mm) and fixed to the mounting piece 1 of the mounting base A by welding.

After the fixed base material B has been installed, the wall material C is laid on the fixed base material B sideways, the male and female connecting portions 5 and 8 of the wall material C are connected, and the mounting portion 7 is self-drilled on the fixed base material B. It is fixed by a fixing tool β composed of a screw and then constructed. Various kinds of accessories are used for the projecting corner, the entering corner, the windows, the eaves, the base, and the like.

[0016]

As described above, according to the outer wall structure of the present invention, since the construction is performed using the dry outer wall material, the RC
Structure and SRC structure are not destroyed by the alkaline aggregate reaction due to the sand containing salt, and the deterioration of the wall foundation can be prevented. A space is formed between the wall foundation and the dry outer wall material, and this space serves as an air cycle ventilation layer. RC
It is possible to form the outer wall in a short period of time by repairing the structure and SRC structure, and with reliable waterproofness. A new outer wall can be formed without breaking the existing outer wall. Significant cost reduction can be achieved compared to rebuilding. Since the existing outer wall has a fireproof structure, the dry outer wall material does not require fireproof performance. It has an external heat insulation structure. There are characteristics and effects.
