Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to a lightweight concrete, a lightweight assembled wall and a building wall construction system constructed thereof. Background Art

[0002] Prefabricated walls are usually composed of ordinary concrete and its steel skeleton. Ordinary concrete refers to cement concrete that is prepared by uniformly mixing cement as a cementitious material, sand and stone as aggregates, water, and admixtures and additives added in a certain proportion when necessary. Its disadvantage is that the sand and stone as aggregates make the prefabricated wall heavy, which not only increases the construction difficulty and cost, but also requires a high load-bearing capacity of lifting equipment such as tower cranes, and makes manual traction and alignment construction difficult. Summary of the invention

[0003] The purpose of the present invention is to provide a lightweight concrete, a lightweight prefabricated wall and a building wall construction system constructed therefrom, so as to solve the problem of heavy weight and high cost of ordinary concrete and prefabricated walls made therefrom.

The prefabricated exterior wall includes a gangue concrete structure and a sandwich insulation layer therein. The gangue concrete structure includes gangue concrete and steel bars cast therein. The gangue concrete is a lightweight concrete formed by using gangue as aggregate instead of stone in ordinary concrete.

[0005] Furthermore, in the lightweight assembled wall provided by the present invention, the sandwich insulation layer is pre-buried in the double-layer coal gangue concrete structure through inner and outer layer connectors.

[0006] Furthermore, in the lightweight assembled wall provided by the present invention, the sandwich insulation layer is close to the outer side.

[0007] Furthermore, in the lightweight assembled wall provided by the present invention, both ends of the inner side surface of the prefabricated exterior wall in the length direction have rectangular notches, and the rectangular notches partially overlap with the projections of both ends of the sandwich insulation layer in the prefabricated exterior wall.

[0009] The present invention further provides a lightweight prefabricated wall, which is a prefabricated interior wall. The prefabricated interior wall is a coal gangue concrete structure. The coal gangue concrete structure includes coal gangue concrete and steel bars cast therein. The steel bars extend out of the coal gangue concrete. The coal gangue concrete is a lightweight concrete formed by using coal gangue as aggregate instead of stone in ordinary concrete.

[0010] The present invention also provides a building wall construction system for the above-mentioned lightweight assembled wall construction, wherein the building wall construction system is a building interior wall, and the building interior wall includes the prefabricated interior wall and the cast-in-place interior walls connected at both ends thereof, and the steel bars of the prefabricated interior wall are implanted in the cast-in-place interior wall.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The lightweight concrete, lightweight prefabricated wall and the building wall construction system constructed by the present invention adopt coal gangue as aggregate to replace the stone in ordinary concrete, so that the industrial waste of coal gangue can be recycled as raw material, avoiding the problem of coal gangue being usually disposed of as waste, and has the advantage of being green and environmentally friendly; coal gangue has the advantage of low material cost compared with stone; the lightweight prefabricated wall made of the lightweight concrete and the construction system thereof can reduce the weight of the lightweight prefabricated wall under the condition of equal volume, facilitate the hoisting and traction of the lightweight prefabricated wall, and reduce the construction difficulty.

[0015] The building wall construction system provided by the present invention can improve the thermal insulation performance and construction efficiency of the building exterior wall when it is a building exterior wall composed of a prefabricated exterior wall, a cast-in-place exterior wall and a cast-in-place insulation layer; the sandwich insulation layer of the prefabricated exterior wall and the cast-in-place insulation layer on the cast-in-place exterior wall are continuously distributed in a projection perpendicular to the exterior wall, thereby avoiding the cold bridge phenomenon, improving the thermal insulation performance of the building exterior wall, and reducing energy consumption.
