Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention attaches a dry type outer wall material to the outer wall of a structure in which an ALC member is attached to a body for imparting makeup, waterproofness, durability, vibration isolation and workability. This is related to the cover structure of the ALC outer wall.

[Conventional technology]

Generally, in a structure using an ALC member, in order to impart cosmetic properties to the outer wall, waterproof property, frost damage prevention, and durability enhancement,
The structure was such that the paint was applied after the ALC member was fixed on the body.

[Problems to be solved by the invention]

However, in the case of such a structure, the durability of the coating film is about 5 years, and since the coating film is formed by spraying, pinholes are considerably generated, which is essentially vulnerable to frost damage.
There was a defect that the C member was destroyed, or the water reached the reinforcing bars and the body to corrode them. Also, the deterioration of the coating film is 5
Since it is around the age, it has to be re-sprayed for maintenance each time, which has the disadvantage of high cost. Furthermore, when forming the base on the uneven decorative surface, not only the mounting surface becomes unstable, but there is also a disadvantage that the ALC member is destroyed by vibration such as an earthquake.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention reuses the threaded portion of the hook bolt which is the fixture of the existing outer wall when constructing the ALC member which becomes the outer wall in the new construction, and special fixtures through the fixture. The furring strips are arranged vertically and horizontally and fixed, and the dry outer wall material is fixed to this with nails, screw screws, and metal fittings, efficiently, easily, and at low cost.
We propose a cover structure for the ALC outer wall, which is free from the fear of frost damage, which is a weak point of ALC members, and has greatly improved heat insulation, aesthetic appearance, durability, and vibration isolation.

It can also be formed as in (b). Further, in FIG. 1, the headstock may be formed on the upper surface of the parapet. Further, it is also possible to form a plurality of steps only on the furring strip 15 on the outer circumference like a hoop and use this as a base. Further, unlike the case of FIGS. 8 (a) and 8 (b), the projecting corner may have a structure in which the furring strip 15 is simply made orthogonal. Further, a cushion material 15d can be attached to the back surface of the reinforcing flat plate 14 as shown in FIG. 14 (a).

As described above, according to the ALC outer wall cover structure of the present invention, the base is easily and inexpensively and efficiently used by using the hook bolts that are used to attach the ALC member to the base of the structure having the ALC member as the outer wall. In addition to being able to easily form a dry type outer wall material that is waterproof, durable, and heat-insulating on its base, it can be formed by absorbing vibrations and irregularities on the decorative surface of the ALC member in a short period of time. It has features that can prevent frost damage, change over time, and corrosion of the body. Also, the appearance is beautiful and ALC
Since there is a gap between the member and the dry type outer wall material, even if there is dew condensation or water leakage, the base does not corrode and there is an advantage in excellent soundproofing. Further, there is no strength reinforcing material in the middle part of one ALC member, but there is a feature that the strength as a base can be sufficiently exhibited by arranging the reinforcing flat plates in a tag shape.
