Abstract

PURPOSE:To facilitate a construction as well as to improve fire-resistance, waterproofing characteristic and durability by laying a sheet-like substance all over an insulating layer fixed to a skeleton through furring strips, and loading and fixing exterior panels thereon. CONSTITUTION:An insulating layer 2 consisting of non-painted plates of a ALC plate is fixed to a skeleton 1 to make a foundation. After that, furring strips 3 and 3 are mounted thereon at a certain pitch, and a metallic sheet-like substance 4 with the shape preservation is laid and fixed all over the furring strips 3 and 3 to form a waterproofing sheet material. Exterior panels 6 are loaded and fixed on the waterproofing sheet material, and a joint material 8 is filled to a cross joint 7a and bed joint 7b.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to external walls of buildings and structures, particularly external wall structures that require fire protection and fire resistance and can be constructed with panels.

[Conventional technology]

In general, ALC plates with a thickness of 100 to 150 mm are refractory, especially fire resistant for 1 hour. This panel has the ability to pass a 2-hour fire resistance test.

[Problem that the invention attempts to solve]

However, although this type of panel has excellent fire resistance,
It had the disadvantages of deteriorating weather resistance, causing cracks, and being inferior to freezing and thawing. Furthermore, since a thick coating film was applied as a finishing material, not only did it increase costs, but it also required repainting every five years.

Furthermore, this type of panel has the disadvantage of being weak against external impacts. Furthermore, conventional AI and C boards used large amounts of caulking material in joints and other joints to waterproof and finish them.

[Means to solve the problem]

In order to eliminate these drawbacks, the present invention uses an unpainted ALC board as a base, constructs an hourglass-like rim on top of it, and lays and fixes a shape-retaining metal sheet material on top of this rim. By using this as a waterproof sheet material and attaching and fixing exterior panels to this sheet material, we propose an exterior wall structure with excellent heat insulation, waterproofness, fire resistance, ease of construction, earthquake resistance, corrosion resistance, and sound insulation. It is.

〔Example〕

An embodiment of the wall structure according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a partially cutaway perspective view showing a typical example of the above-mentioned outer wall structure, where ■ is a body, 2 is a heat insulating layer, 3 is a rim, 4 is a sheet-like material, 6 is an exterior panel, and 8 is a It is a joint material. To explain further, the frame 1 consists of one type of main pillar, stud, etc., and in the figure, C-shaped steel, depending on the case, ■-shaped steel, L-shaped steel, etc. are fixed horizontally or vertically. Thermal insulation layer 2 is A with excellent fire prevention and insulation properties.
An LC board, preferably an unpainted board, is fixed vertically or horizontally to the frame l with nails, bolts, etc., and its size and thickness vary depending on the site of use and purpose. The rim 3 is fixed onto the heat insulating layer 2 via bolts and nuts, and the hook bolt α (second
The bolt portion (shown in the figure) is made longer and protrudes from the heat insulating layer 2, and the furring 3 is fixed to it via a nut β.

In addition, the sheet-like material 4 has the function of removing waterproof material, crank prevention material of the heat insulating layer 2, and caulking material, and is coated on the rim 3 with a thin metal sheet material with a rippled cross section, such as stainless steel (20 microns to 0.1 mm). It is made of asphalt felt (with uneven ridges), etc. Note that one type of fixing device 5 such as a screw is used for fixing to the furring 3. In particular, the connecting portion between the sheet-like materials 4 is one in which two to three crests of the yamabushi are polymerized.

The exterior panel 6 is made of one type, such as a block type or an elongated type, and uses a shape as shown in FIGS. 3(a) to 3(d), for example. The fitting of joint 7 is shown in Figure 4 (a
) and (b). That is, (
a) The figure shows a structure in which the joint 7 is filled with a joint material 8. Φ) The figure shows a joint 7 formed integrally with a base material 9, a metal fitting 10, and a cover material 11. In particular, it is used for vertical joints 7a, and for horizontal joints 7b. is filled with joint material 8.

What has been described above is only one embodiment of the outer wall structure according to the present invention, and the sheet-like material 4 is made of a heat-insulating form 12 with sheet materials 4a interposed on both sides, as shown in FIG.
It is also possible to have an outer wall structure using

[Effects of the Invention] As described above, according to the outer wall structure according to the present invention, ■ effective use of ALC boards with fire retardant and heat insulating properties, and a fire resistant structure (
1 hour). ■It has both design and fire protection properties. ■ Eliminating the weak points of ALC boards, it is possible to create an outer wall structure that is both low cost and highly durable.

■Easy to install. ■Excellent waterproofness. It has the following characteristics.
