Description

Technical Field

[0001] This application relates to the field of partition wall panels, and more particularly to a prefabricated lightweight partition wall panel and its connection structure. Background Technology

[0002] With the acceleration of modern building industrialization and greening, prefabricated buildings have become an important development direction in the construction industry due to their advantages such as high construction efficiency, controllable quality, energy saving and environmental protection. In the interior non-load-bearing partition projects of prefabricated buildings, lightweight partition boards are widely used because of their characteristics such as light weight, high strength, good thermal insulation and sound insulation performance, and strong workability.

[0003] Currently, common prefabricated lightweight partition boards on the market, such as gypsum board and calcium silicate board, usually have their sides prefabricated with male and female tenon structures. During installation, construction workers interlock the male and female tenons of two adjacent partition boards to form a preliminary interlocking connection. Then, special mortar, adhesives (such as construction adhesives, structural adhesives, etc.) or foaming filler materials are applied to the gap between the tenon and the mortise to fill the gap and enhance the connection between the boards.

[0004] Because mortar or glue needs to be filled into the tenon joints, this process is a wet operation on site. The operation procedures are relatively complicated and require high levels of skill and proficiency from the workers. The overall installation progress is slow and needs improvement. Summary of the Invention

[0005] To improve the installation progress of lightweight partition walls, this application provides a prefabricated lightweight partition wall and its connection structure.

[0006] Firstly, the connection structure of the prefabricated lightweight partition wall panel provided in this application adopts the following technical solution:

[0007] A connection structure for a prefabricated lightweight partition wall panel includes a connecting frame, a top frame, connecting ribs, connecting blocks, and supporting ribs. The connecting frame has an installation groove with one open end for insertion into a wall. The top frame is located above the connecting frame and covers the opening of the installation groove. The top frame has a receiving groove. The connecting frame has a first rib located on both sides of the installation groove. The first rib and the connecting frame are spliced ​​to form a through hole. The through hole allows the connecting rib to pass through. The top frame has a second through hole and a first through hole communicating with the receiving groove. The second through hole allows the first rib to be inserted. When the first rib is inserted into the second through hole, the first through hole faces the first through hole, allowing the connecting rib to pass through.

[0008] The top frame has a through hole three, which is located on both sides of the mounting groove. The through hole three is for the support rib to pass through. The connecting frame has slots on both sides for the connecting block to be inserted. The connecting block has two through holes four, which are respectively for the support ribs on the two connecting frames to be inserted.

[0009] A fixing plate is provided on the top frame, the fixing plate is located in the receiving groove, and the fixing plate corresponds to the three through holes. An elastic plate is provided on the fixing plate, the elastic plate is located below the fixing plate, and the elastic plate and the fixing plate form an included angle α, the included angle α is an acute angle. A five through hole is opened on the fixing plate, and a six through hole is opened on the elastic plate. When the elastic plate is attached to the fixing plate, the five through holes and the six through holes are connected. The five through holes and the six through holes are for the support rib to pass through. An annular groove is opened on the support rib, and the annular groove is for the elastic plate to be inserted.

[0010] By adopting the above technical solution, during installation, the wall is inserted into the installation groove, and then the top frame is placed above the connecting frame, so that the first reinforcing bar is inserted into the second through hole. Next, the connecting reinforcing bar is inserted through the first through hole and passes through the first through hole. The top frame and the connecting frame are connected by the connecting reinforcing bar abutting against the inner wall of the receiving groove. Then, the connecting blocks are inserted into the slots on the two connecting frames respectively, and the elastic plate is pressed to make the elastic plate fit against the fixing plate. Then, the supporting reinforcing bars are sequentially passed through the fifth, sixth, third, and fourth through holes until the lower end of the supporting reinforcing bars abuts against the connecting frame. The elastic plate is opened, and it elastically resets and snaps into the annular groove. The elastic plate presses against the inner wall of the annular groove, thereby positioning the lower end of the support rib against the connecting frame. After the support ribs on the two connecting frames pass through the four holes on the connecting block and are positioned, the connection between the two adjacent connecting frames is completed. This replaces the wet construction method of filling the tenon joint with mortar and glue in the traditional male and female tenon structure, simplifies the construction process, reduces the dependence on workers' skills, shortens the construction cycle, realizes the whole dry method of quick installation, and improves the installation progress of lightweight partition wall panels.

[0011] Optionally, the connecting block has a through hole two, which is located between and connects the two through holes four. The connecting block has elastic abutment pieces on both sides, which correspond to the through holes four, and the two elastic abutment pieces face downwards and approach each other.

[0012] By adopting the above technical solution, when the supporting rib passes through the fourth perforation, the supporting rib compresses the elastic clamping plate, causing the elastic clamping plate to deform, thereby allowing the supporting rib to pass through the fourth perforation. Once the supporting rib has completely passed through the fourth perforation and reached the predetermined position, the elastic clamping plate elastically resets and clamps the supporting rib, forming an additional radial clamping force on the supporting rib. When encountering vibrations or inter-story displacement caused by an earthquake, it can absorb and dissipate some of the earthquake energy, preventing the connection structure from brittlely failing due to instantaneous impact, which is beneficial to improving the seismic performance of the partition wall panel.

[0013] Optionally, the connecting frame has a through hole seven, which corresponds one-to-one with the through hole three, and the through hole seven is located between the through hole three and the slot, and the through hole seven is for the support rib to pass through.

[0014] By adopting the above technical solution, when the connecting block is subjected to lateral shear force and attempts to move the supporting ribs, the supporting ribs at the perforation seven will be constrained by the connecting frame, resisting the relative slippage between the connecting block and the connecting frame, thereby enhancing the connection reliability between adjacent connecting frames and reducing the risk of disintegration of the partition wall in earthquake scenarios.

[0015] Optionally, it also includes a cover plate and positioning ribs. The cover plate is provided with a fixing piece. The cover plate covers the receiving groove. The fixing piece is located in the receiving groove. The fixing piece and the cover plate are spliced ​​to form a through hole eight. The through hole eight is for the positioning rib to pass through. The top frame is provided with a second rib. The second rib is located in the receiving groove and on both sides of the receiving groove. The two second ribs are spliced ​​to form a through hole nine. The through hole nine is for the fixing piece to be inserted. When the fixing piece is inserted into the through hole nine, the positioning rib passes through the through hole eight from below the elastic plate, and the elastic plate abuts against the positioning rib. The through hole one is for the positioning rib to pass through.

[0016] By adopting the above technical solution, after the supporting ribs are positioned, the cover plate is placed above the top frame. At the same time, the fixing plate is inserted into the nine-hole, and then the positioning ribs are sent into the through hole one and through the eight-hole. At this time, the elastic plates on both sides press against the positioning ribs, and the positioning ribs press against the fixing plate, thus positioning the cover plate on the top frame. By covering the receiving groove with the cover plate, dust and debris are prevented from entering the receiving groove and corroding the connecting ribs and positioning ribs. At the same time, the cover plate, the top frame, and the connecting frame form a complete outer surface, providing a flat and solid base layer for the subsequent finishing layer (such as putty, paint, wallpaper) construction, which is convenient for construction.

[0017] Optionally, the positioning rib is provided with a positioning groove for the elastic plate to be inserted.

[0018] By adopting the above technical solution, after the positioning rib is fed into the through hole and through the eight holes, the positioning rib is moved until the elastic plate and the positioning groove are aligned. The elastic plate is then elastically reset and locked into the positioning groove. The positioning rib is positioned by the elastic plate abutting against the inner wall of the positioning groove, thus preventing the positioning rib from shifting under vibration.

[0019] Optionally, the fixing piece is an elastic piece, and the fixing piece has inclined surfaces on both sides, the inclined surfaces on both sides are inclined downward and close to each other, and the inclined surfaces on both sides respectively abut against the two ribs.

[0020] By adopting the above technical solution, when the cover plate is closed and the fixing piece is inserted into the perforation nine, the inclined surfaces on both sides of the fixing piece will first contact the two ribs two. During the continued pressing process, the inclined surfaces guide the fixing piece to undergo elastic compression and narrowing, so as to smoothly insert it into the perforation nine formed between the two ribs two. When the fixing piece passes the two ribs two, the fixing piece immediately resets. During the restoration process, the inclined surfaces on both sides adhere to and press against the ribs two, avoiding material damage caused by direct collision of rigid sharp corners.

[0021] Optionally, the two elastic plates are positioned downwards and far apart from each other.

[0022] By adopting the above technical solution, after the positioning rib is fed into the through hole and passes through the perforation hole, the positioning rib continues to move. The positioning rib can press the elastic plate along the surface of the elastic plate, causing the elastic plate to deform, which facilitates the passage of the positioning rib.

[0023] Optionally, the connecting rib is provided with a limiting groove for the supporting rib to be inserted.

[0024] By adopting the above technical solution, the connecting rib is limited by the support rib abutting against the inner wall of the limiting groove, thereby locking the connecting rib in the preset position, preventing the connecting rib from detaching from the perforation, and enhancing the stability of the connection between the top frame and the connecting frame.

[0025] Secondly, this application provides a prefabricated lightweight partition wall panel, which adopts the following technical solution:

[0026] A prefabricated lightweight partition wall panel includes a wall and a connection structure for the prefabricated lightweight partition wall panel.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. It replaces the wet construction method of filling the tenon joint with mortar and glue in the traditional male and female tenon structure, simplifies the construction process, reduces the dependence on workers' skills, shortens the construction cycle, realizes the whole dry method of quick installation, and improves the installation progress of lightweight partition wall panels.

[0029] 2. By setting elastic clamping plates, additional radial clamping force is formed on the supporting ribs. When encountering vibrations or inter-story displacements caused by earthquakes, it can absorb and dissipate some of the seismic energy, avoid brittle failure of the connection structure due to instantaneous impact, and help improve the seismic performance of the partition wall panel.

[0030] 3. Covering the receiving groove with a cover plate prevents dust and debris from entering and corroding the connecting and positioning ribs. At the same time, the cover plate, top frame, and connecting frame form a complete outer surface, providing a flat and solid base layer for subsequent finishing layer construction, which facilitates construction.

[0049] The implementation principle of a prefabricated lightweight partition wall panel in this application embodiment is as follows:

[0050] During installation, the wall 1 is inserted into the mounting groove 21, and then the top frame 3 is placed above the connecting frame 2, so that the first reinforcing bar 9 is inserted into the second through hole 32. Next, the connecting reinforcing bar 4 is inserted through the first through hole 33 and passes through the first through hole 10. The top frame 3 and the connecting frame 2 are connected by the connecting reinforcing bar 4 abutting against the inner wall of the bottom of the receiving groove 31. Then, the connecting blocks 7 are inserted into the slots 22 on the two connecting frames 2 respectively, and the elastic plate 13 is pressed so that the elastic plate 13 fits against the fixing plate 12. Then, the supporting reinforcing bars 8 are inserted according to... The support rib 8 is then perforated through holes 5 (121), 6 (131), 3 (34), 7 (23), and 4 (71) until its lower end abuts against the connecting frame 2. The elastic plate 13 is then released, and it elastically resets and snaps into the annular groove. The elastic plate 13 presses against the inner wall of the annular groove, thereby positioning the lower end of the support rib 8 against the connecting frame 2. After the support ribs 8 on the two connecting frames 2 are perforated through holes 4 (71) on the connecting block 7 and positioned, the connection between the two adjacent connecting frames 2 is completed.

[0051] Then, squeeze one of the elastic plates 13 to make it fit against the fixed plate 12, and send the positioning rib 6 into the through hole 33 and past the squeezed elastic plate 13. Then, place the cover plate 5 above the top frame 3. At the same time, the fixing piece 16 is inserted into the through hole 15. Then continue to move the positioning rib 6 so that the positioning rib 6 passes through the through hole 17 until the elastic plate 13 and the positioning groove 61 are aligned. The elastic plate 13 elastically resets and is inserted into the positioning groove 61. At this time, the elastic plates 13 on both sides press against the positioning rib 6, and the positioning rib 6 presses against the fixing piece 16 to realize the positioning of the cover plate 5 on the top frame 3. This can prevent dust and debris from entering the receiving groove 31 and corroding the connecting rib 4 and the positioning rib 6.

[0052] It replaces the wet construction method of filling the tenon joint with mortar and glue in the traditional male and female tenon structure, simplifies the construction process, reduces the dependence on workers' skills, shortens the construction cycle, realizes the whole dry method of quick installation, and improves the installation progress of lightweight partition wall panels.
