Embodiment 1
[0034] Such as Figure 1-3 As shown, this embodiment provides a wall connection structure on both sides of a prefabricated laminated wall, including a laminated wall 1 and connectors 2. Several groups of connectors 2 are provided on the front and rear sides of the laminated wall 1, and the connectors 2 are in the form of "I" shape, the height of the connector 2 is 300-400mm, and the distance between adjacent connectors 2 on the same side is 500-600mm.
[0035] In this embodiment, "I"-shaped connectors 2 are used to replace the traditional "V"-shaped truss at the joints of the walls on both sides of the laminated wall 1. Compared with the traditional "V"-shaped truss structure, the "V"-shaped Type trusses are unevenly stressed up and down, and the stress surfaces are mainly concentrated on the left and right sides, and the direction of the force gradually changes. However, the shape of the "I"-shaped connector 2 adopted in the present invention is regular, and the stress surfac...
Embodiment 2
[0043] Such as Figure 1-3 As shown, this embodiment provides a method for connecting the walls on both sides of the prefabricated laminated wall 1, including the following steps:
[0044] S1: Fix and arrange the steel bars on the front and rear sides of the laminated wall 1, and then establish two upper and lower formworks 4 on the front and rear sides of the laminated wall 1, and establish several connecting pieces 2 between the two formworks 4. ", the height of the connector 2 is 300-400mm, and the distance between adjacent connectors 2 on the same side is 500-600mm;
[0045] S2: pouring is performed between the two formworks 4 on the front of the laminated wall 1, and the connector 2 is pre-embedded;
[0046] S3: Turn over the trolley to close the mold;
[0047] S4: pouring is performed on the two formworks 4 on the back side of the laminated wall 1, and the connectors 2 are pre-embedded to obtain a finished product.
[0048]In this embodiment, "I"-shaped connectors 2 a...

Abstract
The invention discloses a connecting structure for wall bodies at two sides of a prefabricated composite wall and a method thereof, and relates to the technical field of composite wall assembly. The connecting structure comprises a composite wall and a plurality of groups of connecting parts; the connecting parts are arranged at the front side and the rear side of the composite wall; the connecting parts are I-shaped; the height of the connecting parts is 300-400 mm; and the distance between every two adjacent connecting parts at the same side is 500-600 mm. The connecting method includes the steps that S1, steel bars are fixed and placed at the front side and the rear side of the composite wall, then an upper formwork and a lower formwork are built at the front side and the rear side of the composite wall, and the multiple connecting parts are built between the two formworks; S2, pouring is conducted between the two formworks on the front face of the composite wall, and the connecting parts are pre-buried in the two formworks; S3, a trolley is turned over for die assembly; and S4, pouring is conducted on the two formworks on the back face of the composite wall, the connecting parts are pre-buried in the formworks, and a finished product is manufactured. The connecting structure for the wall bodies at two sides of the prefabricated composite wall and the method thereof have the advantages that the integrity of the composite wall can be guaranteed, the factors of water and electricity pre-burying are considered, deformation and dislocation of the wall bodies at the two sides can be avoided, and the secondary pouring integrity effect is improved.
Description
technical field [0001] The invention relates to the technical field of assembly of laminated walls, in particular to a connection structure and a method for connecting walls on both sides of a prefabricated laminated wall. Background technique [0002] At present, the main structure of open-cut underground stations in domestic subway projects usually adopts a laminated lining structure (that is, a laminated wall) or a composite lining structure. Board, thermal insulation material board, prefabricated outer leaf board, middle cast-in-place layer, prefabricated inner leaf board and other multi-layer structures, generally used in stations. The design concept of the laminated lining structure is to give full play to the structural capacity of the underground wall of the enclosure structure, and participate in permanent work as a part of the main structure, thereby saving engineering investment. Its characteristic is that the underground wall and the inner lining structure are s...
