Description

Technical Field

[0001] The utility model relates to the field of building construction, and particularly relates to a partition structure between walls. Background Technique

[0002] Some fair-faced concrete building exterior walls serve as infill walls, which are components outside the load-bearing of the frame structure. As components outside the frame structure, the infill walls coordinate the loads of vertical components on the same floor, enabling the building to form a complete lateral force resistance system. The parts where the infill walls are connected to the frame columns on both sides need to be treated with weak connection of concrete to prevent the concrete in the infill wall part from changing the load of the frame column and having an adverse impact on the structural force. In actual construction, generally, the construction column is first poured, and after a certain partition is made at the connection part, the infill wall is then constructed. At the same time, there is also a thermal insulation layer in the infill wall. When pouring the infill wall, the thermal insulation layer needs to be fixed in the center of the formwork first.

[0003] The method of pouring successively has the problem that there is a gap between the formwork poured later and the frame column poured earlier. If not handled well, slurry will seep out, affecting the appearance of the joint. And if poured successively, embedded connectors need to be pre-buried in the structural column to ensure a certain connection relationship between the infill wall and the structural column, which requires reserving the position of the embedded parts in the formwork design. Therefore, how to handle the connection between the infill wall and the frame column, which can achieve the appearance effect of fair-faced concrete buildings and at the same time not affect the load of the original frame beam-column structure, is a difficult problem. Summary of the Invention

[0004] Aiming at the problem of how to connect the infill wall and the frame column, the utility model provides a PVC strip for weak connection between the fair-faced concrete exterior wall frame structure and the infill wall, and realizes the weak connection between the frame structure and the infill wall with the PVC strip.

[0005] The technical solution of the utility model:

[0006] A PVC strip for weak connection between the fair-faced concrete exterior wall frame structure and the infill wall, the length of the PVC strip is equal to the height of the infill wall, and both sides of the PVC strip have two wing plates extending outwards, and the overall cross-section of the PVC strip is in the shape of "艹".

[0007] In the formwork pouring system, the PVC strip is used as a partition between the frame column and the infill wall, and the end of the thermal insulation board in the infill wall is stuck in the card slot formed by the two wing plates outside the PVC strip.

[0008] Adjusting bolts are installed on the two wing plates outside the PVC strip, and the end of the bolt is connected to a pressing plate.

[0009] There are perforations on the two wing plates inside the PVC strip, and the PVC strip is fixed by wire binding through the perforations.

[0010] The width of the PVC strip is less than the thickness of the infill wall.

[0011] Advantages of the present invention:

[0012] 1. By using the PVC strip as the partition structure between the fair-faced concrete exterior wall frame structure and the infill wall, it is possible to simultaneously pour the frame structure and the infill wall during casting. The PVC strip can isolate the two casting cavities, with only a certain gap at the edges. The two sides of the PVC strip are respectively embedded in the frame structure and the infill wall, achieving a weak connection between the frame structure and the infill wall.

[0013] 2. The wing plates on the outer side of the PVC strip can serve as the card slots for the insulation layer in the infill wall, facilitating the positioning and fixing of the insulation layer in the formwork. Description of the drawings

[0018] Embodiment 1:

[0019] As Figure 1 , there are two wing plates extending outward on both the front and back sides of the PVC strip. The cross-section of the PVC strip is in the shape of "艹". The installation structure of the PVC strip is as Figure 3 . The PVC strip is used as the partition between the infill wall 3 and the frame column 4. The length of the PVC strip is equal to the height of the infill wall 3. The width of the PVC strip is slightly less than the thickness of the infill wall 3. The left end of the insulation board 2 in the center of the infill wall 3 is stuck in the card slot formed by the two wing plates on the right side of the PVC strip.

[0020] Embodiment 2:

[0021] In this embodiment, the outer wing plates of the PVC strip are improved based on Embodiment 1. Two groups of adjusting bolts are installed on the two outer wing plates to clamp the insulation board 2 by using the adjusting bolts. Further, a backing plate is installed at the end of the adjusting bolts.

[0022] Embodiment 3:

[0023] This embodiment improves upon embodiment 1 by creating holes in the PVC strips. These holes, along with steel wires, allow the PVC strips to be tied and fixed to the reinforcing bars in the structural column.
