Description

Technical Field

[0001] This invention belongs to the field of prefabricated interior partition wall technology, specifically a fine-decoration construction connection mechanism for prefabricated interior partition walls. Background Technology

[0002] With social development and technological advancements, prefabricated buildings are becoming increasingly widespread. Prefabricated buildings are constructed using industrial methods, which reduce energy consumption, improve efficiency, and ensure quality, aligning with the future development direction of architecture. Interior partitions in prefabricated walls are used to divide the interior space of a building. These partitions are non-load-bearing and are generally required to be lightweight and thin.

[0003] Existing precast interior partition walls are generally composed of multiple precast panels connected together. The existing installation structure uses plug-in connection, with connecting steel bars inside the plug joint, and then concrete is poured. The overall construction connection is very troublesome. Moreover, this connection method is very inconvenient for adjusting the flatness of the precast panel connection and the flatness error of the ground surface. In order to solve the above problems, a fine decoration construction connection mechanism for precast interior partition walls is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a connection mechanism for the fine decoration construction of prefabricated interior partition walls in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: a prefabricated interior partition wall finishing construction connection mechanism, including a lower floor slab, an upper floor slab, several prefabricated partition wall panels, several straight positioning plates, and several L-shaped positioning plates. The prefabricated partition wall panels can be stacked together. Positioning slots are provided on both sides and four edges of each prefabricated partition wall panel. The straight positioning plates and the L-shaped positioning plates are inserted into the positioning slots of the prefabricated partition wall panels. A connecting hole penetrating the prefabricated partition wall panel is provided in the positioning slot. A fixing screw is connected between two corresponding straight positioning plates on two sides of the prefabricated partition wall panel. The fixing screw passes through the connecting hole. Locking nuts are threaded to both sides of the fixing screw. A fixing screw is connected between two corresponding L-shaped positioning plates on two sides of the prefabricated partition wall panel. The fixing screw passes through the connecting hole. Locking nuts are threaded to both sides of the fixing screw. The bottom of the L-shaped positioning plate is fixedly connected to the lower floor slab and the upper floor slab. The straight positioning plate has threaded holes on both sides, and an adjusting bolt is internally threaded into each threaded hole. Side plates are welded to the four corners of the straight positioning plate. Threaded holes are also provided on the side plates, and adjusting bolts are threaded into each threaded hole. The upper part of the L-shaped positioning plate has a threaded hole, and an adjusting bolt is internally threaded into each threaded hole. Side plates are welded to both sides of the upper part of the L-shaped positioning plate, and threaded holes are also provided on the side plates, with adjusting bolts threaded into each threaded hole. The bottom of each L-shaped positioning plate is equipped with adjustment pads of various thicknesses.

[0006] In a preferred embodiment, the straight positioning plate has a through hole, and the fixing screw passes through the through hole.

[0007] In a preferred embodiment, the L-shaped positioning plate has a second through hole, and the second fixing screw passes through the second through hole.

[0008] In a preferred embodiment, cement mortar is applied into the positioning slot.

[0009] In a preferred embodiment, the top surface of the lower floor slab has a pre-reserved inner groove, and the L-shaped positioning plate is inserted into the inner groove.

[0010] In a preferred embodiment, the bottom surface of the upper floor slab has a pre-reserved inner groove II, and the L-shaped positioning plate is inserted into the inner groove II.

[0011] In a preferred embodiment, the L-shaped positioning plate has a mounting hole at its lower part, and an anchor bolt is inserted into the mounting hole. The L-shaped positioning plate is fixedly connected to the lower floor slab and the upper floor slab through the anchor bolt.

[0012] In a preferred embodiment, both the first inner groove and the second inner groove are filled with cement mortar.

[0013] In a preferred embodiment, the joints between the prefabricated partition walls are filled with cement mortar, and the joints between the prefabricated partition walls and the lower floor slab and the upper floor slab are filled with cement mortar.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, the structure uses a straight positioning plate and a fixing screw to form a whole partition wall from multiple prefabricated partition wall panels. The L-shaped positioning plate and the fixing screw can be used to fix the prefabricated partition wall panels to the upper and lower floor slabs, thereby realizing the installation of the prefabricated partition wall panels. The overall structure uses standard parts for connection, which makes assembly convenient and quick and has good practicality.

[0015] 2. In this invention, the structure uses the adjusting bolts of the straight positioning plate and the adjusting bolts of the L-shaped positioning plate to move the front and rear sides of the prefabricated partition wall panel, thereby adjusting the verticality between two adjacent prefabricated partition wall panels. This achieves precise adjustment of the flatness of the prefabricated partition wall panel connection. Furthermore, the installation height of the L-shaped positioning plate is finely adjusted using adjusting shims, thereby adjusting the vertical installation error of the inner partition wall composed of prefabricated partition wall panels. This mainly avoids the problem of the prefabricated partition wall panel tilting due to unevenness of the floor slab. Thus, the inner partition wall composed of prefabricated partition wall panels can be finely adjusted, making the installation more accurate and the operation more convenient and faster.

[0016] 3. In this invention, the structure fills the joint with cement mortar and uses the adjusting bolts 2 on the side plate 1 and 4 on the side plate 2 to hold the prefabricated partition wall panel in place. This effectively prevents the prefabricated partition wall panel from becoming unstable due to the gap between the fixing screw and the connecting hole, thus ensuring the stability of the prefabricated partition wall panel as an internal partition wall.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The following will combine Figures 1-6 A detailed description is provided of a prefabricated interior partition wall finishing construction connection mechanism according to an embodiment of the present invention.

[0021] Example:

[0022] This invention provides a connection mechanism for the finishing construction of prefabricated interior partition walls, as per the embodiments of the present invention. Figure 1 , Figure 2 and 3 As shown, the structure includes several prefabricated partition wall panels 3 and several straight positioning plates 4. The straight positioning plates 4 are metal parts. The prefabricated partition wall panels 3 can be stacked together. Positioning slots 6 are opened on both sides and four sides of the prefabricated partition wall panels 3. The straight positioning plates 4 are inserted into the positioning slots 6 of the prefabricated partition wall panels 3. The positioning slots 6 are provided with connecting holes 9 that penetrate the prefabricated partition wall panels 3. A fixing screw 7 is connected between the corresponding straight positioning plates 4 on both sides of the prefabricated partition wall panels 3. The fixing screw 7 passes through the connecting holes 9. Locking nuts 8 are threaded on both sides of the fixing screw 7. The prefabricated partition wall panels 2 are stacked together to form an internal partition wall structure. The fixing screw 7 passes through the connecting holes 9 of the prefabricated partition wall panels 3. Then, the straight positioning plates 4 are connected together on both sides of the fixing screw 7 by the locking nuts 8. This fixes two adjacent prefabricated partition wall panels 3 together to form the overall structure of the internal partition wall. The positioning slot 6 of this structure can roughly position the position of the support positioning plate 4, and at the same time, the positioning slot 6 ensures that the structure of the straight positioning plate 4 does not protrude from the outer surface of the prefabricated partition wall panel 3.

[0023] refer to Figure 3 and Figure 4 As shown, a through hole 23 is provided on the straight positioning plate 4, and a fixing screw 7 passes through the through hole 23. This structure uses the through hole 23 to allow the fixing screw 7 to pass through the positioning plate 4, thereby facilitating the locking nut 8 to lock the two straight positioning plates 4 together.

[0024] refer to Figure 1 , Figure 2 and Figure 5As shown, the structure includes a lower floor slab 1, an upper floor slab 2, and several L-shaped positioning plates 5. The L-shaped positioning plates 5 are metal parts and are inserted into the positioning slots 6 of the prefabricated partition wall slab 3. A fixing screw 10 is connected between the two corresponding L-shaped positioning plates 5 on the two sides of the prefabricated partition wall slab 3. The fixing screw 10 passes through the connecting hole 9, and locking nuts 11 are threaded on both sides of the fixing screw 10. The bottom of the L-shaped positioning plate 5 is fixedly connected to the lower floor slab 1 and the upper floor slab 2. This structure uses the fixing screw 10 to pass through the connecting hole 9 and the locking nuts 11 to connect the two L-shaped positioning plates 5 together. The fixing screw 10 limits the position of the prefabricated partition wall slab 3, and the L-shaped positioning plates 5 can be fixed on the lower floor slab 1 and the upper floor slab 2, so that the internal partition wall composed of the prefabricated partition wall slab 3 can be fixed between the upper and lower floor slabs, thereby ensuring that the internal partition wall composed of the prefabricated partition wall slab 3 and the upper and lower floor slabs form an integral structure. The positioning slot 6 of this structure can roughly position the L-shaped positioning plate 5, and at the same time, the positioning slot 6 ensures that the upper structure of the L-shaped positioning plate 5 does not protrude from the outer surface of the prefabricated partition wall 3.

[0025] refer to Figure 5 and Figure 6 As shown, the L-shaped positioning plate 5 has an installation hole 27 at the bottom, and an anchor bolt 28 is inserted into the installation hole 27. The L-shaped positioning plate 5 is fixedly connected to the lower floor slab 1 and the upper floor slab 2 through the anchor bolt 28. In this structure, the L-shaped positioning plate 5 is fixedly connected to the upper and lower floor slabs through the anchor rod 28.

[0026] refer to Figure 5 and Figure 6 As shown, the L-shaped positioning plate 5 has a through hole 24, and the fixing screw 10 passes through the through hole 24. This structure uses the through hole 24 to allow the fixing screw 10 to pass through the L-shaped positioning plate 5, so that the locking nut 8 can lock the two straight positioning plates 4 together.

[0027] refer to Figure 1 As shown, the top surface of the lower floor slab 1 has a pre-reserved inner groove 25. The L-shaped positioning plate 5 is inserted into the inner groove 25. The setting of the inner groove 25 in this structure ensures that the structure on the L-shaped positioning plate 5 will not protrude from the top of the lower floor slab 1.

[0028] refer to Figure 1 As shown, the bottom surface of the upper floor slab 2 has a pre-reserved inner groove 26. The L-shaped positioning plate 5 is inserted into the inner groove 26. The setting of the inner groove 26 in this structure ensures that the structure on the L-shaped positioning plate 5 will not protrude from the bottom surface of the upper floor slab 2.

[0029] refer to Figures 3-6As shown, threaded holes 12 are provided on both sides of the straight positioning plate 4, and adjusting bolts 13 are threadedly connected to the threaded holes 12. Threaded holes 317 are provided on the upper part of the L-shaped positioning plate 5, and adjusting bolts 318 are threadedly connected to the threaded holes 317. This structure can move the front and rear sides of the prefabricated partition wall panel 3 by rotating the adjusting bolts 13 and 318 in the threaded holes 12 and 317, thereby adjusting the verticality between two adjacent prefabricated partition wall panels 3, and thus achieving precise adjustment of the flatness of the connection between the prefabricated partition wall panels 3.

[0030] refer to Figure 1 As shown, each of the L-shaped positioning plates 5 is provided with an adjustment pad 22 at its bottom. The adjustment pad 22 has multiple models and thicknesses. This structure uses the adjustment pad 22 to finely adjust the installation height of the L-shaped positioning plate 5, thereby adjusting the vertical position installation error of the internal partition wall composed of the prefabricated wall cutting panels 3. This can mainly avoid the problem of the prefabricated wall cutting panels 3 tilting due to the unevenness of the top surface of the lower floor slab 2.

[0031] refer to Figures 3-6 As shown, side plates 14 are welded to the four corners of the straight positioning plate 4. Threaded holes 15 are opened on the side plates 14, and adjusting bolts 16 are threaded onto the threaded holes 15. Side plates 19 are welded to the upper two sides of the L-shaped positioning plate 5. Threaded holes 20 are opened on the side plates 19, and adjusting bolts 21 are threaded onto the threaded holes 20. This structure uses the adjusting bolts 16 on the side plates 14 and the adjusting bolts 21 on the side plates 19 to hold the prefabricated partition wall 3 in place, thereby preventing the prefabricated partition wall 3 from becoming unstable due to the gap between the fixing screw and the connecting hole 9.

[0032] refer to Figure 1 and Figure 2 As shown, cement mortar is applied into the positioning slot 6. Applying cement mortar into the positioning slot 6 can cover the straight positioning plate 4 structure in the positioning slot 6, thereby improving the aesthetics and overall integrity of the prefabricated partition wall panel 3 connection.

[0033] Reference Figure 1 As shown, cement mortar is applied into both the inner groove 1 25 and the inner groove 2 26. This structure uses cement mortar to cover the L-shaped positioning plate 5 structure in the inner groove 1 25 and the inner groove 2 26, thereby making the upper and lower floor slabs more aesthetically pleasing and flat.

[0034] refer to Figure 1As shown, the joints between the prefabricated partition wall panels 3 are all filled with cement mortar, and the joints between the prefabricated partition wall panels 3 and the lower floor slab 1 and the upper floor slab 2 are also filled with cement mortar. This structure uses cement mortar to seal the joints between the prefabricated partition wall panels 3 and the joints between the prefabricated partition wall panels 3 and the lower floor slab 1 and the upper floor slab 2, thereby weakening the gaps in the prefabricated interior partition walls. At the same time, the cement mortar can connect and reinforce the prefabricated partition wall panels 3 and the prefabricated partition wall panels 3 and the lower floor slab 1 and the upper floor slab, making the entire prefabricated interior partition wall structure more stable.

[0035] The implementation principle of the prefabricated interior partition wall finishing construction connection mechanism according to an embodiment of this application is as follows: In use, the operator first places the prefabricated partition wall panel 3 vertically on the lower floor slab 1. Then, the fixing screw 10 passes through the connecting hole 9 of the prefabricated partition wall panel 3. Next, the L-shaped positioning plate 5 is fitted onto the fixing screw 10 through the through hole 24, and the lower part of the L-shaped positioning plate 5 is inserted into the inner groove 25 of the lower floor slab 1. Then, the locking nut 11 is used to connect the L-shaped positioning plate 5 to the prefabricated partition wall panel 3, and it is inserted into the positioning slot 6 of the prefabricated partition wall panel 3. Then, the lower floor slab is positioned according to the position of the mounting hole 27 on the L-shaped positioning plate 5. Finally, the anchor rod 28 is inserted to fix the L-shaped positioning plate 5 onto the lower floor slab 1. When positioning plate 5 is installed, adjusting pads 22 are added according to the flatness of the lower floor slab 1 to adjust the height of L-shaped positioning plate 5. After it is fixed, prefabricated partition wall panels 3 are stacked on the upper and left and right sides in sequence. To connect the prefabricated partition wall panels 3, first pass the fixing screw 7 through the connecting hole 9, then put the two straight positioning plates 4 on both sides of the fixing screw 7, and connect them together with locking nuts 8, thereby fixing the two prefabricated partition wall panels 3 together. The connection method between the prefabricated partition wall panel 3 and the upper floor slab 2 is the same as the connection between the prefabricated partition wall panel 3 and the lower floor slab 2. The L-shaped positioning plate 5 will be inserted into the inner groove 26 of the upper floor slab 2. According to the above installation method, multiple prefabricated partition wall panels 3 can be combined together to form a prefabricated inner partition wall. During installation, the prefabricated partition wall panel 3 can be adjusted by rotating the adjusting bolts 13 and 18 in the threaded holes 12 and 17, thereby adjusting the verticality between two adjacent prefabricated partition wall panels 3 and achieving precise adjustment of the flatness of the connection between the prefabricated partition wall panels 3. Furthermore, rotating the adjusting bolts 16 on the side plate 14 and 21 on the side plate 29 can hold the prefabricated partition wall panel 3 in place, thereby preventing the prefabricated partition wall panel 3 from becoming unstable due to the gap between the fixing screw and the connecting hole 9. After the prefabricated partition wall panel 3 is completed, the user uses cement mortar to seal the joints between the prefabricated partition wall panels 3 and the joints between the prefabricated partition wall panel 3 and the lower floor slab 1 and the upper floor slab 2, thereby weakening the gaps in the prefabricated interior partition wall. At the same time, the cement mortar can reinforce the connection between the prefabricated partition wall panels 3 and between the prefabricated partition wall panels 3 and the lower floor slab 1 and the upper floor slab, making the entire prefabricated interior partition wall structure more stable. In addition, the cement mortar can cover the L-shaped positioning plate 5 structure in the inner groove 1 25 and the inner groove 2 26, thereby making the upper and lower floor slab planes more beautiful and flat. Similarly, the cement mortar can cover the straight positioning plate 4 structure in the positioning slot 6, thereby improving the aesthetics and overall integrity of the connection of the prefabricated partition wall panel 3.
