Problems solved by technology

[0040] In addition, in the modified version of Fig. 12(B), the depth of the strip-shaped groove on the side of the heat-insulating layer is 10 mm, which has less heat insulation defects. However, since the strip-shaped groove of the extruded cement board is molded, the insulation The strip-shaped groove of the heat layer is formed by the incision process of the subsequent processing of the formed plate. Therefore, the lamination of the extruded cement board and the heat insulation layer according to the designed shape is a complicated and precise operation, which improves the ventilation function. From the point of view, the point of view of heat insulation defect, and the point of view of production, that is, the effect of improving the ventilation function is relatively small, the production is complicated and difficult, and the heat insulation function is lost due to the incision through the belt-shaped groove, so the effect of implementation Small, and the construction of imparting air-permeable structure by laying and pasting the composite panels on the concrete exterior wall is the same as the case of using the composite panels in Fig. 12(A) cumbersome, or more cumbersome, and difficult, low-productivity work, so in the construction of the external wall structure developed by the applicant of prior art example 2 (Fig. 11), use Fig. 12 of prior art example 3 (A) type of composite paneling to be implemented

Embodiment Construction

[0200] [Composite panel 1 (Figure 5, Figure 6)]

[0201] Composite panel 1, typically, is used as the outer screed formwork of concrete exterior wall W, and Fig. 5 (A) is the perspective view observed from cement board (external decoration substrate) 1A side, Fig. 5 (B) is from The front view seen from the cement board side, Fig. 6(A) is a longitudinal sectional view, and Fig. 6(B) is an enlarged view of part B of Fig. 6(A).

[0202] Composite panel 1, as shown in Figure 6(A), is a laminated panel of heat insulation layer 1B and cement board 1A, heat insulation layer 1B is extruded polystyrene foam (JISA9511) with a thickness T3 of 75mm, cement Board 1A, as shown in FIG. 6(B), can use magnesia cement board 1A-1 with magnesium oxide and silica sand as the main components and embedded glass fiber non-woven fabric GC on both sides. It has a thickness of T212mm and a specific gravity of 0.9 to 1.1. The bending strength is 100~120kgf / cm 2 , moisture permeability resistance 14m 2...

Abstract

The object of the present invention is to lay air-permeable external heat-insulating composite panels for the external wall structure that suppresses condensation inside the external wall in reinforced concrete buildings with external heat insulation, and to construct the outside of the panels in a cost-effective manner. The moisture-permeable structure made of cheap plastered walls can be easily modified into a breathable structure by laying face bricks on the outer surface when the outer wall is renewed. The solution is: on the thermal insulation layer (1B) of foamed plastics, configure banded grooves (G) for ventilation, and paste it with a cement board (1A) layer with lower moisture permeability resistance than the thermal insulation layer (1B), As a composite panel (1), the composite panel (1) is laid on the concrete exterior wall W, and as an external heat-insulating exterior wall, the lower end of the strip groove (G) group of the composite panel (1) is airtight The strip groove (G) is used as the air heat insulation layer, and at the same time, on the outer surface of the cement board (1A), the exterior finishing finishing with a lower moisture permeability resistance than the cement board (1A) is carried out to make a permeable For the wet external heat insulation external wall, when the external decorative surface material is replaced with a face brick with high moisture permeability resistance, the lower end of the strip-shaped groove (G) of the composite panel (1) can be easily converted into an air-permeable surface. External thermally insulated facades.

Description

technical field [0001] The present invention relates to a moisture-permeable exterior wall structure of a reinforced concrete exterior heat-insulating building. When constructing the exterior wall structure, a composite panel used as an outer dummy box of the concrete exterior wall, and a dado applied to the lower end of the composite panel Demarcation edge hardware, in more detail, relates to vapor-permeable exterior wall structures that are easily retrofitted to breathable exterior thermally insulated exterior walls, composite paneling with a breathable The utility model relates to a dado boundary hardware piece for refitting a ventilating structure, and belongs to the technical field of construction. Background technique [0002] External heat-insulated buildings made of reinforced concrete cover the outside of the concrete frame with a heat-insulating layer, so it can suppress the cracking of the concrete frame caused by the thermal stress of the sun, and because the con...
