Single-sided prefabricated concrete steel wire net rack insulation board wall and construction method thereof

Abstract

The invention relates to a single-sided prefabricated concrete steel wire net rack insulation board wall and a construction method thereof. The wall is provided with a single-sided prefabricated concrete steel wire net rack insulation board and a cast-in-place concrete inner wall which are fixedly connected into a whole, and the single-sided prefabricated concrete steel wire net rack insulation board comprises a steel wire net rack sandwich insulation board and a prefabricated concrete outer wall; and the prefabricated concrete outer wall forms a semi-covered edge structure on the top surfaceand the bottom surface of a thermal insulation material layer close to the outer side edge. During on-site construction, structural steel bars of the single-sided prefabricated concrete steel wire netrack insulation board and the inner wall are installed in an aligned mode, a steel wire net on the inner side of the steel wire net rack sandwich insulation board and the structural steel bars are pulled and fixed through pulling and connecting steel bars, an inner wall inner side form is installed, and the concrete inner wall is cast between the thermal insulation material layer and the inner side form in situ. Due to the fact that the single-sided prefabricated concrete steel wire net rack insulation board and cast-in-place concrete inner wall main bars are more convenient to pull and connect, connection is firmer, the process is easier to control, and therefore the construction quality of a corresponding cast-in-place wall can be obviously improved.

Description

technical field [0001] The invention relates to a cast-in-place exterior wall body with a prefabricated exterior wall insulation board and a construction method thereof. Background technique [0002] At present, the common prefabricated external wall insulation board is a three-layer sandwich structure, with a steel wire grid sandwich insulation board in the middle, and prefabricated concrete inner and outer leaf walls on the inner and outer sides, which can realize the integration of structure and insulation. Due to factory prefabrication, the quality is stable, and it also saves on-site concrete construction man-hours. But the disadvantage is that the connection operation between the prefabricated external wall insulation board and the main reinforcement of cast-in-place components such as cast-in-place walls and connecting beams is inconvenient. In order to realize the connection, some pre-embed connectors in the prefabricated inner leaf wall, and some need to reserve ho...

Problems solved by technology

But the disadvantage is that the connection between the prefabricated external wall insulation board and the main reinforcement of cast-in-place components such as cast-in-place walls and connecting beams is inconvenient.

In order to realize the connection, some prefabricated connectors are embedded in the prefabricated inner leaf wall, and some need to reserve holes in the prefabricated inner leaf wall, which increases the difficulty of manufacturing the prefabricated external wall insulation board, and involves the construction of the wall on site. The quality and precision of the connection structure of prefabricated external wall insulation boards are not easy to guarantee, resulting in inconvenience in the construction of the corresponding walls, and it is difficult to control the quality of the construction process
