Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to a top fixing connector for a prefabricated partition wall. Background Technology

[0002] Currently, many buildings use prefabricated walls for internal partitioning. Prefabricated walls are efficient and easy to assemble and disassemble, so more and more buildings are using them to partition interior spaces. Patent publication CN117468603A discloses a method for installing and fixing prefabricated walls. The method disclosed uses bolts or screws to directly fix the wall to the ceiling. This method of fixing the wall directly with bolts or screws has two drawbacks. First, the wall has poor resistance to torsion. When the wall is impacted by external objects, it is very easy for the wall to twist, which reduces the connection strength between the wall and the ceiling. Second, the wall can easily transmit vibrations directly to the ceiling, causing discomfort to upstairs residents. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a top fixing connector for prefabricated partition walls. When the prefabricated partition wall vibrates or shakes under external force, the blocking and buffering effect of the connecting channel steel plate can reduce the vibration on the ceiling, thereby reducing the discomfort caused to upstairs residents. At the same time, the impact on the connection strength between the first fixing plate and the ceiling is also relatively small.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A top fixing connector for a prefabricated partition wall includes a first fixing plate, a second fixing plate, and a connecting channel steel plate. The two ends of the connecting channel steel plate are respectively fixedly engaged with the first fixing plate and the second fixing plate. The first fixing plate is flat, the second fixing plate is flat, and the connecting channel steel plate is perpendicular to the first fixing plate and the second fixing plate. The first fixing plate and the second fixing plate are parallel and do not contact each other. The first fixing plate has a first fixing hole, and the second fixing plate has a second fixing hole.

[0006] The method of using this type of top fixing connector is as follows: First, the first fixing plate is used to fix and connect to the ceiling of the building, and the second fixing plate is used to fix and connect to the prefabricated partition wall. During connection, the first fixing plate can be fixed to the ceiling by screws or expansion bolts passing through the first fixing hole, and the second fixing plate can be fixed and connected to the prefabricated partition wall by screws passing through the second fixing hole. After the connection is completed, the top installation of the prefabricated partition wall is completed. After the top installation of the prefabricated partition wall is completed, since the first fixing plate and the second fixing plate are connected and fitted together by connecting channel steel plates, the first fixing plate and the second fixing plate do not directly contact each other. The three sides of the connecting channel steel plate are fixed to the first fixing plate by welding, and the fixing method with the second fixing plate is the same. Therefore, in this type of fixing connector, the connecting channel steel plate transmits force between the first fixing plate and the second fixing plate.

[0007] When the prefabricated partition wall vibrates or shakes under external force, the vibration of the ceiling can be reduced due to the buffering effect of the connecting channel steel plate, thereby reducing the discomfort caused to the upstairs residents. At the same time, the impact on the connection strength between the first fixed plate and the ceiling is also relatively small.

[0008] Optionally, there are multiple first fixing holes, and the first fixing holes are distributed on both sides of the connecting channel steel plate.

[0009] Optionally, there are multiple second fixing holes, and the second fixing holes are distributed on both sides of the connecting channel steel plate.

[0010] Optionally, it also includes a pearl cotton padding layer, which is disposed on the second fixed plate, and the connecting channel steel plate and the pearl cotton padding layer are respectively located on both sides of the second fixed plate.

[0011] A pearl cotton pad is provided on one side of the second fixed panel. The pearl cotton pad is a flexible material. After the prefabricated partition wall is fixed together with the second fixed panel, the pearl cotton pad is located between the second fixed panel and the prefabricated partition wall. The presence of the pearl cotton pad can buffer the second fixed panel and the prefabricated partition wall.

[0012] Optionally, a plastic waterproof membrane is provided on one side of the first fixing plate. The plastic waterproof membrane is tightly bonded to the first fixing plate, and the plastic waterproof membrane and the connecting channel steel plate are located on both sides of the first fixing plate.

[0013] The specific plastic waterproof membrane can be a PE membrane, a PP membrane, or a PVC membrane. After the first fixing plate is fixed to the ceiling, the plastic waterproof membrane is located between the first fixing plate and the ceiling. This can prevent the condensate on the ceiling from directly contacting the first fixing plate, thereby slowing down the corrosion and aging rate of the first fixing plate.

[0014] Optionally, there are multiple connecting channel steel plates, and all the connecting channel steel plates do not contact each other.

[0015] Optionally, a plastic sleeve is provided in the second fixing hole, and the length of the plastic sleeve is equal to the depth of the second fixing hole.

[0016] After the second fixing plate is fixed to the prefabricated partition wall by means of screws, the screws are located in the plastic sleeve of the second fixing hole. Both the second fixing plate and the first fixing plate are steel plates. After the plastic sleeve is set, the bolt is located in the plastic sleeve. When the prefabricated partition wall is twisted or vibrates relative to the second fixing plate, the plastic sleeve can reduce the twisting and vibration transmission between the screw and the second fixing plate.

[0017] Optionally, the outer wall of the plastic sleeve (which may be, but is not limited to, made of PPR material) is bonded to the wall of the second fixing hole.

[0018] The beneficial effects of this utility model are: when the prefabricated partition wall vibrates or shakes under the action of external force, the vibration of the ceiling can be reduced due to the blocking and buffering effect of the connecting channel steel plate, thereby reducing the discomfort caused to the upstairs residents. At the same time, the impact on the connection strength between the first fixed plate and the ceiling is also relatively small. Attached Figure Description

The first fixing plate 1 has a first fixing hole 101, and the second fixing plate 2 has a second fixing hole 201.

[0028] The method of using this type of top fixing connector is as follows: First, the first fixing plate 1 is used to fix and connect to the ceiling of the building, and the second fixing plate 2 is used to fix and connect to the prefabricated partition wall. During connection, the first fixing plate 1 can be fixed to the ceiling by screws or expansion bolts passing through the first fixing hole 101, and the second fixing plate 2 can be fixed and connected to the prefabricated partition wall by screws passing through the second fixing hole 201. After the connection is completed, the top installation of the prefabricated partition wall is completed. After the top installation of the prefabricated partition wall is completed, since the first fixing plate and the second fixing plate 2 are connected and fitted together by the connecting channel steel plate 3, the first fixing plate 1 and the second fixing plate 2 do not directly contact each other. The three sides of the connecting channel steel plate 3 are fixed to the first fixing plate 1 by welding, and the fixing method with the second fixing plate 2 is the same. Therefore, in this type of fixing connector, the connecting channel steel plate 3 transmits force between the first fixing plate 1 and the second fixing plate 2.

[0029] When the prefabricated partition wall vibrates or shakes under external force, the vibration of the ceiling can be reduced due to the blocking and buffering effect of the connecting channel steel plate 3, thereby reducing the discomfort caused to the upstairs residents. At the same time, the impact on the connection strength between the first fixed plate 1 and the ceiling is also relatively small.

[0030] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, there are multiple first fixing holes 101, and the first fixing holes 101 are distributed on both sides of the connecting channel steel plate 3.

[0031] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, there are multiple second fixing holes 201, and the second fixing holes 201 are distributed on both sides of the connecting channel steel plate 3.

[0033] A pearl cotton pad 5 is provided on one side of the second fixed plate 2. The pearl cotton pad 5 is a flexible material. After the prefabricated partition wall is fixed together with the second fixed plate 2, the pearl cotton pad 5 is located between the second fixed plate 2 and the prefabricated partition wall. The presence of the pearl cotton pad 5 can buffer the second fixed plate 2 and the prefabricated partition wall.

[0034] As attached Figure 1 Appendix Figure 2 and appendix Figure 3As shown, a plastic waterproof membrane is provided on one side of the first fixed plate 1. The plastic waterproof membrane is tightly bonded to the first fixed plate 1. The plastic waterproof membrane and the connecting channel steel plate 3 are located on both sides of the first fixed plate 1, respectively.

[0035] The specific plastic waterproof membrane can be a PE membrane, a PP membrane, or a PVC membrane. After the first fixed plate 1 is fixed to the ceiling, the plastic waterproof membrane is located between the first fixed plate 1 and the ceiling. This can prevent the condensate on the ceiling from directly contacting the first fixed plate 1, thereby slowing down the corrosion and aging rate of the first fixed plate 1.

[0036] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, there are multiple connecting channel steel plates 3, and all the connecting channel steel plates 3 do not contact each other.

[0037] As attached Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, a plastic sleeve 6 is provided inside the second fixing hole 201, and the length of the plastic sleeve 6 is equal to the depth of the second fixing hole 201.
