External enclosure weight-reduction pre-fabricated wall connecting joint and construction method thereof

Abstract

The invention provides an external enclosure weight-reduction pre-fabricated wall connecting joint and a construction method thereof. The external enclosure weight-reduction pre-fabricated wall connecting joint comprises a first pre-fabricated double-sided composite wall and a second pre-fabricated double-sided composite wall; the first pre-fabricated double-sided composite wall and the second pre-fabricated double-sided composite wall are spliced in the vertical direction and are connected and fixed through a cast-in-situ beam; inserting ribs and partition boards are disposed at the upper endof the first pre-fabricated double-sided composite wall; the inserting ribs are buried in the first pre-fabricated double-sided composite wall and are partially exposed out of the upper end of the first pre-fabricated double-sided composite wall; the portions, exposed out of the first pre-fabricated double-sided composite wall, of the inserting ribs penetrate through the partition boards to extend into the cast-in-situ beam; a first pre-buried part is buried in the lower end of the second pre-fabricated double-sided composite wall; a second pre-buried part is buried in the upper end of the cast-in-situ beam; the second pre-fabricated double-sided composite wall is fixed to the cast-in-situ beam in a matched mode through the first pre-buried part and the second pre-buried part; and accordingly construction and popularization of a pre-fabricated enclosure wall are facilitated.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a prefabricated wall connection structure and a construction method thereof. Background technique [0002] With the development of prefabricated buildings, prefabricated double skin walls are increasingly used in prefabricated buildings. It is mentioned in GBT51231-2016, the technical standard structure specification for prefabricated concrete buildings, that traditional prefabricated walls are connected with steel bars to holes, and the vertical connection is realized by integral pouring of concrete. In the actual installation process, it is necessary to insert the steel bars into the corresponding holes. Since the number of steel bars in this connection node is large, and the inner diameter of the hole is only slightly larger than the diameter of the steel bars, it will increase the difficulty of on-site construction, and there are still Concrete grouting is no...
