Dry-hang external wall insulation board and novel application thereof as dismounting-free building template

Abstract

The invention discloses a dry-hang external wall insulation board and a novel application thereof as a dismounting-free building template. The dry-hang external wall insulation board comprises a panel, upper and lower wall boards, two side wall boards, a bottom plate and an insulation core material, wherein the panel is arranged at the top ends of the wall boards; the outer side surface of the upper wall board extends out of the upper side surface of the panel; a bulk water slope is arranged between the top edge of the outer side surface of the upper wall board and the bottom edge of the upper side surface of the panel; the lower side surface of the panel extends out of the outer side surface of the lower wall board; the part of the panel, extending out of the lower wall board forms a pressure plate mounted by being matched with the bulk water slope; a pressure plate slope is arranged between the bottom edge of the lower side surface of the panel and the top edge of the outer side surface of the lower wall board; a pouring connection piece is embedded between the panel and the bottom plate; the pouring connection piece comprises a fixing rod, a nut at the outer end of the fixing rod and a screw rod matched with the nut; the nut is arranged at the end of the bottom plate; the screw rod extends out of the bottom plate; a U-shaped opening positioning sleeve is arranged on the screw rod; fastening nuts are arranged at the two ends of the U-shaped opening positioning sleeve. The dry-hang external wall insulation board is suitable for dismounting-free self-insulation self-decoration templates of cast-in-situ shear walls and beam columns.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials and building templates, more precisely, relates to a dry-hanging external wall thermal insulation board used as a building template without dismantling and a construction method thereof.

Problems solved by technology

[0002] The basic structure of the existing dry-hanging external wall insulation board is: an insulation layer is arranged in a rectangular frame formed by four side wall panels, and a panel is arranged on the insulation layer. The top surface of the siding is flat, and after the wall is formed, rainwater and snow water can easily seep into the cracks along the flat siding, causing leakage accidents in the cracks

The second is that the outer surface of the wallboard is a simple plane. After the insulation board is installed as a wall, the insulation strip in the board seam will push the caulking mortar outward under the action of thermal expansion, resulting in a gap between the caulking mortar and the insulation board. Cracks, even cause the caulking mortar to fall off, causing water seepage on the wall, reducing the insulation effect, and in severe cases, the wall is damaged due to leakage

The third is that when there is no bottom plate on the opposite side of the panel, the deformation stress of the panel due to temperature, dryness and humidity is not restricted by the corresponding bottom plate, and it is very easy to produce deformation

There are the following defects: 1: There are hidden dangers of debonding and delamination between the two-sided cement board and the polystyrene foam board pasted in it; 2. When pouring, the gravity of the concrete is transmitted to the inner and outer cement boards through the flexible polystyrene foam board , easy to cause displacement and damage to the board body; 3. After the board body is displaced and deformed, it is impossible to bind the solid board joints. Under the action of the gravity of the concrete, the grout leakage is serious; 4. There are many construction links and a long period , The cost is high, and the wall surface is prone to cracks and cracks after the wall is completed
