Leakage-proof sandwich thermal insulation concrete outer wall board based on horizontal joints and vertical joints

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...

Problems solved by technology

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 extruded polystyrene board, and then plastered, due to the flexibility of several materials Cracks are easy to occur due to different thermal expansion and contraction, which is one of the main reasons for water seepage
