Basement double-layer overlapping prefabricated outer wall

Abstract

The invention discloses a basement double-layer overlapping prefabricated outer wall. The basement double-layer overlapping prefabricated outer wall comprises a double-layer overlapping prefabricated plate connected between an upper floor and a lower floor, the double-layer overlapping prefabricated plate comprises a first prefabricated wall plate and a second prefabricated wall plate, a casting concrete layer is arranged between the first prefabricated wall plate and the second prefabricated wall plate, and the first prefabricated wall plate and the second prefabricated wall plate are connected through truss bars. A plurality of inversed-U-type steel bars are arranged at the position, close to the upper portion, inside the casting concrete layer, and closed hoops are arranged on the lower portion of the first prefabricated wall plate and the lower portion of the second prefabricated wall plate. Compared with the prior art, the basement double-layer overlapping prefabricated outer wall is connected with the floors more firmly, connection between the double-layer overlapping wall plates is more stable, and convenience is provided for cast-in-place concrete.

Description

technical field [0001] The invention relates to the field of construction, in particular to a double-layer laminated prefabricated exterior wall installed in a basement. Background technique [0002] At present, the exterior wall of the basement is mainly formed by in-situ pouring. During construction, the workload of formwork support and steel bar binding is heavy, and there are many problems such as cracking and leakage caused by incomplete concrete pouring on site; especially in the special environment of the basement, a more reliable and durable outer wall is required. The double-layer laminated slab mainly used in the upper shear wall structure is used in the basement exterior wall instead of the cast-in-place shear wall, so that the construction of the basement exterior wall can also meet the requirements of building industrialization. The prefabricated double-layer laminated prefabricated prefabricated slab can Used as the stress reinforcement of the basement exterio...

Problems solved by technology

During construction, the workload of formwork support and steel bar binding is heavy, and there are many problems such as cracking and leakage caused by incomplete concrete pouring on site; especially in the special environment of the basement, a more reliable and durable outer wall is required. The double-layer laminated slab mainly used in the upper shear wall structure is used in the basement exterior wall instead of the cast-in-place shear wall, so that the construction of the basement exterior wall can also meet the requirements of building industrialization. The prefabricated double-layer laminated prefabricated prefabricated slab can Used as the stress reinforcement of the basement exterior wall, although this double-layer laminated prefabricated slab has good compactness, high waterproof performance, and is easy to install, it only needs to be hoisted in place and then poured concrete in the double-layer laminated slab. The construction is quick and saves However, if the double-layer laminated slab in the upper shear wall structure is directly applied to the outdoor wall of the basement, there are problems such as insufficient reliability of the connection between prefabrication and cast-in-place joints, and easy cracking and leakage in the joint area.
