Embodiment Construction

[0016] Below in conjunction with embodiment, further illustrate the present invention.

[0017] see figure 1 , figure 2 , a sandwich insulation concrete exterior wall panel based on horizontal joints and vertical joints to prevent leakage. From the outside to the inside, it consists of a reinforced concrete outer leaf 1 (outer layer) with a thickness of 50mm and an extruded polystyrene board 2 with a thickness of 75mm. 1, a reinforced concrete inner leaf 7 with a thickness of 200mm, and a reinforced concrete outer leaf 1 (inner layer) with a thickness of 30mm. The reinforced concrete outer leaf 1 of the outer layer is provided with grooves around it, and between two adjacent grooves There is a seam 4 with a width of 10mm, and the inside of the seam 4 is filled with a rubber strip 8 with a thickness of 10mm. The exterior of the seam 4 is sealed with a waterproof sealant 9 compatible with concrete, and the thickness of the waterproof sealant 9 is 10mm.

Abstract

The invention discloses a leakage-proof sandwich thermal insulation concrete outer wall board based on horizontal joints and vertical joints. The outer wall board comprises reinforced concrete and an extruded polystyrene board; the extruded polystyrene board is arranged between an outer reinforced concrete leaf and an inner reinforced concrete leaf, rabbets are formed in the periphery of the outer reinforced concrete leaf, a joint is arranged between two adjacent rabbets, and is filled with rubber strips, and the outer portion of the joint is blocked by waterproof seal gum compatible with concrete; the rabbets are arranged and are in lap joint, connection of the outer wall board is facilitated, the joint is arranged between the rabbets, according to blockage between the joints, the rubber strips are plugged into the rabbets, the waterproof seal gum is used for blockage, the lap joint positions of the rabbets have the good seal performance, the phenomenon that in a traditional steel structure residence outer wall maintaining structure, the mounting and contact portions of steel beams and steel columns with brickwork or strip plates are not tight in blockage and are likely to generate cracks is avoided, and the phenomenon that a masonry wall is subject to plastering, and the pasted extruded polystyrene board is prone to falling is avoided.

Description

technical field [0001] The invention relates to a prefabricated steel structure residential external wall maintenance structure, in particular to a sandwich thermal insulation concrete external wall panel based on horizontal joints and vertical joints to prevent leakage. Background technique [0002] In steel structure houses, the water seepage of the exterior wall mainly occurs in the contact parts between the exterior wall maintenance structure and the steel columns and steel beams. The traditional external wall maintenance structure mainly adopts concrete aerated block masonry or ALC autoclaved aerated concrete slab installation; there are gaps with steel columns and steel beams during block masonry or slab installation, and the gap sealing is mainly Mortar is used to block, and at the same time, steel wire mesh or alkali-resistant mesh cloth needs to be added to prevent cracks at the contact parts of different materials, and then plastered on the wall, pasted with extrud...
