Compared with traditional construction methods, prefabricated buildings can shorten the construction period, reduce construction site construction waste, and reduce resource consumption and environmental pollution through factory prefabrication and on-site assembly. However, in the interlayer structure, the interlayer structure based on assembly still has the following technical defects: first, there is a defect of large welding work amount in the actual construction process; further, compared with the traditional interlayer structure, it has the defect of complex operation process. Second, like the traditional interlayer structure, both ignore the adverse effects of horizontal forces under conditions such as earthquakes. Based on this, the present embodiment aims to provide a prefabricated building interlayer for concrete structures to simultaneously improve the above technical defects.

In this embodiment, the transition plates are steel plates, which are fixed on the inner bottoms of the U-shaped structures of the fixed parts through pre-embedded steel bars. The sliding particles are specifically carbon powder.
[0038] The two ends of the support parts 4 are movably clamped in the U-shaped structures of the corresponding fixed parts 2, and the sliding particles are placed between the lower surfaces of the support parts 4 and the transition plates. The interlayer main bodies are detachably installed on the support parts 4. In this embodiment, the support parts 4 are specifically steel beams.
[0039] In the specific implementation, if it is necessary to build the building interlayer based on the area expansion demand. First, evenly spread the carbon powder on the transition plate; then, clamp the two ends of the support parts 4 in the U-shaped structures of the fixed parts; finally, install the interlayer main body on the support parts 4. Thus, the fabricated installation of the entire building interlayer is realized, without the need for wet work on site and without the need for welding work, greatly simplifying the building difficulty and construction complexity of the building interlayer. At the same time, the sliding parts 3 arranged between the support parts 4 and the fixed parts 2 can realize the relative position fine adjustment between the support parts 4 and the transition plate through the sliding particles, avoiding the adverse effects of the horizontal force transmitted by the support parts 4 on the original building main body 1 under rigid cooperation.

At this time, the corresponding excess design can avoid the direct collision between the support member 4 and the fixing member 2 when the sliding particles slide along the transition plate.
[0042] Similarly, a gap is also provided between the support member 4 and the building main body 1 to reduce the horizontal force transmission and avoid the adverse effects on the structure of the building main body 1. In actual application, the gap between the support member 4 and the building main body 1 is in the range of 30mm-80mm. Specifically, the gap between the support member 4 and the building main body 1 in the embodiment is 50mm.
[0043] As a preferred embodiment, a buffer plate is also provided on the inner side wall of the U-shaped structure of the fixing member to further avoid the abrasion of the support member 4 on the structure of the fixing member 2. In specific implementation, the buffer plate is nailed to the fixing member 2. In the embodiment, the buffer plate is specifically a polytetrafluoroethylene plate, and the thickness thereof is in the range of 3mm-8mm. Preferably, the thickness of the polytetrafluoroethylene plate used in the embodiment is 5mm.
[0044] As a preferred embodiment, in order to avoid the influence on the normal use of the corresponding building without installing the building interlayer, the fixing member 2 protrudes from the thickness of the building main body in the horizontal direction, and the thickness is in the range of 150mm-250mm. In the embodiment, the specific thickness of the fixing member 2 protruding from the building main body is 200mm.
