Description

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 a repaired outer wall for RC construction etc., new construction,
The RC structure is the same as the S structure, and the SRC structure is C on the existing wall.
Shaped steel (lip channel steel), L-shaped steel (equal side or unequal side angle steel), or square pipe (square steel pipe) is attached with anchor bolts as a mounting base, and a wall material with a male and female connection structure on the left and right , Was attached to the attachment base by a fixture such as a self-drilling screw.

[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, cracks, concrete peeling, and the like have been increasing in recent years due to alkali-aggregate reaction, and countermeasures against them are urgently desired. Furthermore, the outer wall formed in this way is inferior in workability, and if there is unevenness (unevenness) in the wall foundation, adjustment is not effective and a separate member for adjusting unevenness is required, There was a problem in workability and finish.

[0004]

In order to eliminate such drawbacks, the present invention is to construct an outer wall material having a male-female connecting structure on the left and right on a newly constructed or an existing outer wall as a foundation. In this structure, it 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 regular intervals. Then, fix one surface of the fixed base on the mounting base so that they are orthogonal to each other with a fixing tool such as bolts, and connect the outer wall material to the other surface of the fixed base by connecting the male and female and fixing it with the wall base. The outer wall structure has a cushion material formed between the mounting base and the fixed base.

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. 1 and 2 show examples of horizontal lining, and FIGS. 3 and 4 show examples of vertical lining. A is a cushion material, B is a mounting base, C is a fixed base, D is a wall material,
α is a wall base and β is a fixture.

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.

As shown in FIG. 5, the cushion material A is integrally formed on the back surface of the mounting base B, which will be described later, so that when the mounting base B is fixed to the wall base α, the wall base α is uneven (uneven). For mounting the mounting base B without any unevenness, and the material thereof is, for example, soft synthetic resin foam, rubber, synthetic rubber or the like, and has at least cushioning properties.

The mounting base B is a mounting piece 1 as shown in FIG.
The flat bar (flat steel) which is widely used, or a C-shaped rope (lip groove-shaped rope), a square pipe (square steel pipe) or the like (not shown).

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

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

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

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

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

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

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 D as shown in FIG. 7B is installed horizontally on an existing outer wall made of RC structure to be renovated. Therefore, a mounting base B made of flat steel (thickness 3 mm × width 50 mm) and having a cushion material A made of a soft synthetic resin foam adhered to the back surface is provided with a pitch P ₂ (about 600 to 3000 mm).
Then, it is fixed on the wall base α by a fixing tool β consisting of anchor bolts without any landing. Next, the thickness is 2.3 mm, the fixing parts 2, 3
Long fixed base C made of Z-shaped steel with a length of 30 mm
Are fixed to the mounting piece 1 of the mounting base B by welding at a pitch P ₁ (about 450 to 600 mm).

After the installation of the mounting base B is completed, the wall material D is laid sideways on the fixed base C, the male and female connecting portions 5 and 8 of the wall material D are connected, and the mounting portion 7 is self-drilled on the fixed base C. It is fixed by a fixing tool β composed of a screw and is constructed from the lower stage to the upper stage. In addition, out corner, entering corner, around windows,
Various accessories are used for eaves, foundations, etc.

[0017]

As described above, according to the outer wall structure of the present invention, the cushion material absorbs the unevenness of the wall base,
Since the mounting base can be fixed without unevenness, construction is quick and easy. The dry outer wall material can prevent the RC and SRC structures from being destroyed by the alkaline aggregate reaction due to the sand containing salt, and prevent the deterioration of the wall foundation. A space is formed between the wall foundation and the dry outer wall material, and this space serves as an air cycle air passage. The RC structure and SRC structure can be repaired in a short period of time, and the outer wall can be formed 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.
