Description

Technical Field

[0001] The present application relates to the technical field of prefabricated panels, and in particular to a prefabricated panel connection structure. Background Art

[0002] Precast panels are the floor slabs used in early buildings, which are the modules or panels needed for engineering projects. They are called precast panels because they are precast concrete parts produced and processed in the prefabrication yard and then transported directly to the construction site for installation.

[0003] Most of the existing connections between prefabricated panels are inconvenient to assemble and disassemble. If installation errors occur between prefabricated panels, these prefabricated panels cannot be reused, resulting in a waste of resources and poor practicality. Therefore, a prefabricated panel connection structure is needed to improve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present application provides a prefabricated panel connection structure with high practicality, which completes the disassembly and assembly of the first prefabricated panel and the second prefabricated panel through the cooperation of a connecting mechanism and a limiting mechanism, thereby improving work efficiency.

[0006] (II) Technical solution

[0008] Two limiting mechanisms are symmetrically arranged on the first prefabricated plate, one of which includes a clamping block, one end of which is arranged in an arc structure, a fixed plate is fixedly installed on one of the working grooves of the first prefabricated plate, a clamping slot is provided on the second prefabricated plate, a sliding slot is provided on the fixed plate, two telescopic columns are symmetrically fixedly installed on the sliding slot, one end of the two telescopic columns away from the sliding slot is fixedly connected to the clamping block, the clamping block is slidingly connected to the sliding slot and the clamping slot respectively, the two telescopic columns are both provided with springs, the two ends of each spring are fixedly connected to the sliding slot and the clamping block respectively, a sliding rod is fixedly installed on the clamping block, a sliding hole is provided on the fixed plate, and the sliding rod is slidingly connected to the sliding hole.

[0009] Preferably, the connecting mechanism includes two bolts, a connecting plate is fixedly installed on the first prefabricated plate, a connecting hole is opened on the second prefabricated plate corresponding to the connecting plate, two first limiting holes are symmetrically opened on the connecting plate, and two second limiting holes are symmetrically opened on the second prefabricated plate, one of the first limiting holes and one of the second limiting holes are connected by a screw, and the two bolts are respectively screwed with the two screws.

[0010] Furthermore, an auxiliary plate is fixedly mounted on the sliding rod.

[0011] Furthermore, rubber pads are attached to the inner walls of the two bolts.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present application provides a prefabricated panel connection structure, which has the following beneficial effects:

[0014] The prefabricated plate connecting structure is configured such that the first prefabricated plate and the second prefabricated plate are gradually brought closer together, and since one end of the two clamping blocks is set to an arc structure, the second prefabricated plate squeezes the two clamping blocks so that the multiple telescopic columns drive the multiple springs to perform a compression operation, thereby retracting the clamping blocks into the sliding grooves. When the positions of the clamping grooves and the clamping blocks coincide with each other, the elastic force of the two springs themselves drives the clamping blocks to reset, so that the clamping blocks and the clamping grooves are clamped, thereby limiting the second prefabricated plate, and completing the connection operation of the first prefabricated plate and the second prefabricated plate through the cooperation of the connecting mechanism, thereby realizing the connection of the first prefabricated plate and the second prefabricated plate. When the first prefabricated plate and the second prefabricated plate need to be disassembled, the limiting operation of the connecting mechanism on the second prefabricated plate is released, and the two sliding bars are pulled, so that the two clamping blocks are separated from the two clamping grooves, and the disassembly can be completed by moving the second prefabricated plate, thereby improving work efficiency and having high practicality.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example

[0022] See also Figure 1-3 A prefabricated panel connection structure comprises a first prefabricated panel 1 and a second prefabricated panel 2, wherein the first prefabricated panel 1 and the second prefabricated panel 2 are connected by a connection mechanism, both ends of the first prefabricated panel 1 and the second prefabricated panel 2 are provided with working grooves, the connection mechanism comprises two bolts 6, a connection plate 3 is fixedly mounted on the first prefabricated panel 1, a connection hole 4 is provided on the second prefabricated panel 2 corresponding to the connection plate 3, two first limiting holes are symmetrically provided on the connection plate 3, two second limiting holes are symmetrically provided on the second prefabricated panel 2, one of the first limiting holes and one of the second limiting holes are connected by a screw rod 5, and two bolts 6 are respectively screwed on the two screw rods 5, and the arrangement of the two screw rods 5 and the two bolts 6 makes the connection between the first prefabricated panel 1 and the second prefabricated panel 2 more stable.

[0023] See also Figure 1-4Two limiting mechanisms are symmetrically arranged on the first prefabricated plate 1, one of which includes a clamping block 11, one end of which is set as an arc structure, a fixed plate 7 is fixedly installed on one of the working grooves of the first prefabricated plate 1, a clamping slot 8 is provided on the second prefabricated plate 2, a sliding slot 9 is provided on the fixed plate 7, and two telescopic columns 10 are symmetrically fixedly installed on the sliding slot 9, and one end of the two telescopic columns 10 away from the sliding slot 9 is fixedly connected to the clamping block 11, and the clamping block 11 is slidably connected to the sliding slot 9 and the clamping slot 8 respectively, and springs 12 are respectively mounted on the two telescopic columns 10, and the two ends of each spring 12 are fixedly connected to the sliding slot 9 and the clamping block 11 respectively. By gradually approaching the first prefabricated plate 1 and the second prefabricated plate 2, since one end of the two clamping blocks 11 is set as an arc structure, the second prefabricated plate 2 squeezes the two clamping blocks 11, so that the multiple telescopic columns 10 drive the multiple springs 12 to compress The second prefabricated plate 2 is then moved to a position where the two blocks 11 are retracted and retracted, thereby allowing the blocks 11 to be retracted into the slots 9. When the slots 8 and the blocks 11 are aligned, the elastic force of the two springs 12 drives the blocks 11 to be reset, thereby allowing the blocks 11 to be clamped with the slots 8, thereby limiting the position of the second prefabricated plate 2. The connection operation of the first prefabricated plate 1 and the second prefabricated plate 2 is completed through the cooperation of the connecting mechanism, thereby realizing the connection between the first prefabricated plate 1 and the second prefabricated plate 2. A sliding rod 13 is fixedly installed on the block 11, and a sliding hole is provided on the fixed plate 7. The sliding rod 13 is slidably connected with the sliding hole. When the first prefabricated plate 1 and the second prefabricated plate 2 need to be disassembled, the limiting operation of the second prefabricated plate 2 by releasing the connection mechanism is performed, and the two sliding rods 13 are pulled, thereby allowing the two blocks 11 to be disengaged from the two slots 8. The second prefabricated plate 2 can be moved to complete the disassembly, thereby improving work efficiency and having high practicality.

[0024] See also Figure 1-4 An auxiliary plate 14 is fixedly mounted on the slide bar 13 , and the installation of the auxiliary plate 14 facilitates better pulling of the slide bar 13 .

[0025] See also Figure 2 It should also be noted that rubber pads 15 are attached to the inner walls of the two bolts 6. The provision of the two rubber pads 15 increases the friction force, making the screw rod 5 and the bolt 6 more stable.

[0026] In summary, when the prefabricated plate connection structure is in use, the first prefabricated plate 1 and the second prefabricated plate 2 are gradually brought closer together to allow the connection plate 3 to be clamped with the connection hole 4. Since one end of the two clamping blocks 11 is set as an arc structure, the second prefabricated plate 2 squeezes the two clamping blocks 11, so that the multiple telescopic columns 10 drive the multiple springs 12 to perform compression operations, so that the clamping blocks 11 are retracted into the sliding grooves 9. When the positions of the clamping grooves 8 and the clamping blocks 11 coincide with each other, the elastic force of the two springs 12 drives the clamping blocks 11 to reset, thereby The clamping block 11 is clamped with the clamping slot 8, thereby limiting the position of the second prefabricated panel 2, and the connection between the first prefabricated panel 1 and the second prefabricated panel 2 is completed by the cooperation of the two screw rods 5 and the two bolts 6. When the first prefabricated panel 1 and the second prefabricated panel 2 need to be disassembled, the limiting operation of the screw rods 5 and the bolts 6 on the first prefabricated panel 1 and the second prefabricated panel 2 is released, and the two sliding rods 13 are pulled by the two auxiliary plates 14, so that the two clamping blocks 11 are disengaged from the two clamping slots 8, and the second prefabricated panel 2 can be moved to complete the disassembly.
