Example Embodiment

[0035] Such as figure 1 As shown, the prefabricated concrete sandwich thermal insulation exterior wall of the present invention includes an outer prefabricated reinforced concrete slab 1, a transverse laminated rib 5, a longitudinal laminated rib 6, an insulation board 3, an insulation waterproof mortar 2, an inner prefabricated reinforced concrete board 4 and a main body Structurally connected, load-bearing embedded parts 7 and self-weight embedded parts 8 (such as Picture 8 , Picture 9 Shown). The shape of the plate end meets the requirements of structural waterproofing. The thickness of the outer precast reinforced concrete slab 1 is not less than 50mm in accordance with the design specification, and the steel bars 41 (such as Figure 7 As shown), the diameter and spacing of the steel bars are determined by the load. Laminated ribs 5, 6 (such as Figure 5 with Image 6 (Shown) not only has the pulling effect of the inner and outer prefabricated reinforced concrete slabs 1,...

Abstract

The invention aims to provide a precast concrete sandwiched heat-insulation external wall, which can meet various structural systems. The precast concrete sandwiched heat-insulation external wall for realizing the purpose is characterized by comprising an outer side precast concrete plate, heat-insulation waterproof mortar, overlapped ribs, an inner side precast concrete plate and a connecting part used for being connected with a main body structure, the heat-insulation waterproof mortar and the overlapped ribs are arranged between the outer side precast concrete plate and the inner side precast concrete plate, and the overlapped ribs are connected with the inner side precast reinforcement concrete plate and the outer side precast reinforcement concrete plate in a pulled manner, and are sealed in the heat-insulation waterproof mortar.

Description

technical field [0001] The invention relates to thermal insulation walls, in particular to wall components suitable for industrialized residential construction methods. Background technique [0002] China's urbanization process is rapid, and the rapidly growing demand for housing has stimulated the rapid development of the housing industry. Our country has a large low-cost labor force, which has fueled the growth of construction companies and created serious problems. Due to the difficult working environment in the construction industry, construction personnel entering the construction industry are relatively low-quality, highly mobile, and lack of training. If you want to ensure the quality of the project, the management cost is very high, and even uncontrollable. In the absence of high-quality construction personnel, how to ensure the quality of the project, not only to meet the rapidly expanding housing market demand, but also to ensure high-quality housing construction ...
