Description
Technical Field
The utility model belongs to the technical field of the building, concretely relates to prefabricated outer wall off-load structure with even wall spare.
Background
In the prior art, for a building needing to arrange an external frame on an external wall, a wall connecting piece is usually arranged in the building, and a supporting or unloading structure is formed by connecting the wall connecting piece and the external frame; the wall connecting piece in the traditional technology mainly has the following two construction modes:
firstly, referring to fig. 1, in this way, a lower outer wall 2 is constructed first, then a cast-in-place slab 8 is cast on the lower outer wall 2, a wall connecting member 6 is embedded in the cast-in-place slab 8, the wall connecting member 6 generally protrudes out of the end face of the cast-in-place slab 8, then an upper outer wall 3 is constructed, and at this time, a hole through which a connecting rod passes is reserved on the upper outer wall 3. However, in this way, because the installation of the existing external frame 1 has variability, the position of the reserved hole is very easy to be inaccurate, and an additional hole needs to be additionally arranged; and the later plugging of the holes is difficult, and the water leakage probability is increased.
Secondly, referring to fig. 2, in this way, the lower outer wall 2 is also constructed firstly, but different from the first way, the hollow pipe and the wall connecting piece 6 are embedded in the cast-in-situ slab 8, and the wall connecting piece 6 is connected with the hollow pipe, so that the influence on the cast-in-situ slab 8 when the protruding end face of the wall connecting piece 6 is arranged can be avoided, and the reserved hole can be avoided. However, this approach places greater demands on the placement of the outriggers 1 and less variability in the mounting of the outriggers; and after post-cutting, holes will likewise be present to be treated.
Moreover, with the continuous development of the concept and practice of the fabricated building, the prefabricated components such as the KT board and the like are increasingly put into the building industry, and because the cast-in-place laminated board has certain thickness limitation, the thickness of the cast-in-place laminated board is generally 140mm, so that the two construction modes of the wall connecting piece can have the following problems in the prior art if the construction mode of the KT board and the post-cast layer is adopted:
1. the KT plate has the thickness of the KT plate, so that the overall thickness of a post-cast layer in the cast-in-place laminate is reduced, the pre-embedded depth of the wall connecting piece is limited, and the structural stress is influenced;
2. because the KT plate is a prefabricated plate, if a hollow pipe embedding mode is adopted, the embedding height of the hollow pipe can be increased, and the actual embedding length of the embedded hollow pipe is insufficient due to the fact that the overall thickness of a post-cast layer is reduced; when the hollow pipe is pre-buried for setting up at the top terminal surface of KT board, more can influence the combination between post-cast layer and the KT board, equally can influence the structure atress, and the aftertreatment is troublesome.
