Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to an assembly wall installation structure for building engineering. Background Technology
[0002] Prefabricated walls typically utilize galvanized light steel keel as a supporting framework and high-strength magnesium oxide flat panels as non-removable panels. Environmentally friendly, flame-retardant, lightweight slurry is poured inside the high-strength magnesium oxide flat panels, eventually solidifying and forming the wall. This allows a significant amount of on-site work to be transferred to the factory, where the prefabricated walls are manufactured and transported to the construction site for reliable assembly and installation.
[0003] Chinese utility model patent CN222362646U discloses a prefabricated wall panel. The right side of the wall panel has an upper fixing plate and a lower fixing plate. The upper fixing plate has a first fixing hole, and the lower fixing plate has a second fixing hole. The first and second fixing holes are coaxially arranged. The left side of the wall panel has a slot. First, the left and right sides of the two walls are brought close together and aligned. Then, the two walls are pushed into contact. The upper fixing plate on the right side of the wall panel pushes the sliding plate on the left side of the wall panel inward, compressing a first spring. Simultaneously, the lower fixing plate on the right side of the wall panel enters the slot on the left side of the wall panel. When the fixing block is directly above the first fixing hole, the fixing block falls into the first and second fixing holes, thus securing the two walls together. Furthermore, both sides of the wall panel have insertion holes and insertion rods. When the insertion rod is inserted into the insertion hole, a locking block on the insertion rod engages with a slot in the insertion hole to achieve a locked fixation.
[0004] While the above technologies can achieve a stable connection between walls, once the walls are connected, they are difficult to separate, replace or dismantle, and are difficult to recycle. Utility Model Content
[0005] To address the technical problem that existing prefabricated walls are difficult to replace or disassemble, resulting in poor wall recycling efficiency, this utility model provides a prefabricated wall installation structure for building engineering that is easy to replace and disassemble and has good recycling efficiency.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] The prefabricated wall installation structure for building engineering includes a first wall and a second wall. The first wall has a plug on its right side and a slot on its left side. The plug mates with the slot. The first wall has at least one mounting groove on its right side, in which a connecting component is installed. The second wall has a first slot corresponding to the mounting groove on its left side, and a second slot is formed on the side wall of the first slot. The connecting component includes a mounting frame, a first screw, a first threaded sleeve, and at least one retaining plate. The first end of the first screw passes through the left side wall of the mounting frame and is inserted into the mounting frame. The first threaded sleeve is located within the mounting frame and threadedly engages with the first screw. The first threaded sleeve has at least one first inclined surface facing the right side of the mounting frame. The retaining plate has a first inclined surface that engages with the first inclined surface. The second inclined surface, which is parallel to the first inclined surface, also includes a T-shaped slide rail and a T-shaped slide groove that are connected to each other. One of the T-shaped slide rail and the T-shaped slide groove is set on the first inclined surface, and the other is set on the second inclined surface. The inner side wall of the mounting frame is provided with at least one horizontal guide groove to the right. One end of the card plate has a first protrusion that mates with the guide groove. The right side of the mounting frame has a clearance hole, and the card plate passes through the clearance hole. The end of the card plate away from the first protrusion has a second protrusion. When the first screw is rotated, the card plate is pushed to the right. When the second protrusion reaches the second slot, the card plate is displaced in a direction perpendicular to the pushing direction, so that the second protrusion is engaged in the second slot. When the first screw is rotated, the card plate is retracted to the left, and the second protrusion is disengaged from the second slot.
[0008] Furthermore, the first screw sleeve has two first inclined surfaces, which are located on the front and rear sides of the first screw sleeve, respectively. Each first inclined surface corresponds to a locking plate. The inner front wall and inner rear wall of the mounting frame are provided with guide grooves. Rotating the first screw drives the locking plate to be fed to the right. When the second protrusion reaches the second locking groove, one of the two locking plates is displaced in the forward direction, and the other locking plate is displaced in the rearward direction.
[0009] Furthermore, the mounting groove extends a certain depth from the front side to the rear side of the first wall. The mounting groove has a T-shaped cross-section and includes a vertical groove and a horizontal groove. The vertical groove is perpendicular to and connected to the horizontal groove, and the connecting component is installed in the horizontal groove.
[0010] Furthermore, a limiting block is provided at the second end of the first screw. The limiting block is located in the vertical groove, and the vertical projection of the limiting block in the vertical plane partially falls outside the vertical projection of the transverse groove in the vertical plane.
[0011] Furthermore, the front side of the first wall is provided with an inclined baffle located above the mounting groove.
[0012] Furthermore, the front side of the first wall is rotatably connected to a first connecting hook, and the front side of the second wall is fixedly provided with a fixing block. It also includes a second screw and a second screw sleeve. One end of the second screw is fixedly connected to the fixing block, and the second screw sleeve is threadedly connected to the second screw. The end of the second screw sleeve away from the fixing block is rotatably connected to a second connecting hook. The rotation axes of the second screw sleeve and the second connecting hook are coaxial. When the second screw sleeve is rotated, the second connecting hook moves to the right until the first connecting hook and the second connecting hook are connected and tightened.
[0013] Furthermore, there are two mounting slots, which are symmetrically arranged with the insert block as the center.
[0014] The beneficial effects of this utility model are:
[0015] This invention achieves an efficient, stable, and easily adjustable connection between the first and second walls through a simple locking mechanism and convenient disassembly. Specifically, when the first screw is rotated to push the locking plate to the right, the interaction between the first and second inclined surfaces causes the locking plate to shift perpendicular to the pushing direction, allowing the second protrusion to accurately engage with the second slot, ensuring a tight connection between the first and second walls. The T-shaped slide rail and T-shaped groove work together to ensure the stability and accuracy of the locking plate's movement, preventing loosening or detachment and improving the overall stability of the wall structure. When wall disassembly is required, the first screw is rotated in the opposite direction, causing the locking plate to retract to the left, and the second protrusion disengages from the second slot. The entire process requires no complex tools or steps, greatly improving construction efficiency and facilitating later maintenance or modification work. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0025] Reference Figures 1 to 4 This utility model provides an assembly wall installation structure for building engineering.
[0026] like Figures 1 to 4As shown, this embodiment provides a prefabricated wall installation structure for building engineering, including a first wall 1 and a second wall 2. The right side of the first wall 1 has an insert 3, and the left side of the second wall 2 has a slot 4. The insert 3 cooperates with the slot 4. Alternatively, the insert 3 can be located on the left side of the second wall 2, and the slot 4 on the right side of the first wall 1. The right side of the first wall 1 has at least one mounting groove 5, in which a connecting component is installed. The left side of the second wall 2 has a first slot 6 corresponding to the mounting groove 5, and a second slot 7 is formed on the side wall of the first slot 6. The connecting component includes a mounting frame 8, a first screw 9, a first threaded sleeve 10, and at least one retaining plate 11. The first end of the first screw 9 passes through the left side wall of the mounting frame 8 and is inserted into the mounting frame 8. The first threaded sleeve 10 is located within the mounting frame 8 and threadedly engages with the first screw 9. The first threaded sleeve 10 has at least one first inclined surface 12 facing the right side of the mounting frame 8. The retaining plate 11 has a surface parallel to the first inclined surface 12. The second inclined surface 13 also includes a T-shaped slide rail 14 and a T-shaped slide groove 15 that are connected to each other. This allows for relative sliding between the clamping plate 11 and the first threaded sleeve 10, and also prevents the clamping plate 11 from derailing during sliding. One of the T-shaped slide rail 14 and the T-shaped slide groove 15 is located on the first inclined surface 12, and the other is located on the second inclined surface 13. The inner side wall of the mounting frame 8 is provided with at least one horizontally right-facing guide groove 16, and one end of the clamping plate 11 has a groove that mates with the guide groove 16. The first protrusion 17 has a clearance hole 18 on the right side of the mounting frame 8. The clamping plate 11 passes through the clearance hole 18. The end of the clamping plate 11 away from the first protrusion 17 has a second protrusion 19. Rotating the first screw 9 pushes the clamping plate 11 to the right. When the second protrusion 19 reaches the second slot 7, the clamping plate 11 is displaced perpendicular to the pushing direction, so that the second protrusion 19 is engaged in the second slot 7. Rotating the first screw 9 retracts the clamping plate 11 to the left, and the second protrusion 19 disengages from the second slot 7.
[0027] like Figure 1 As shown, it should be noted that a structure for the left side of the second wall 2 can be provided corresponding to the left side of the first wall 1, and a structure for the right side of the first wall 1 can be provided corresponding to the right side of the second wall 2, thus realizing the connection between multiple first walls 1 and second walls 2.
[0028] The first screw 9 can be driven by electric or manual means. When driven by electric means, the motor can rotate forward or backward. The motor is installed in the mounting slot 5 and the motor drive shaft is connected to the first screw 9, thereby controlling the first screw 9 to rotate forward or backward. When driven by manual means, the mounting slot 5 extends at least partially through to the front side of the first wall 1 to ensure that there is operating space for the operator to manually drive the first screw 9 on the front side of the first wall 1.
[0029] like Figures 1 to 4As shown, the mounting groove 5 can be set as a square groove or other shaped groove. Preferably, the mounting groove 5 penetrates a certain depth from the front side to the rear side of the first wall 1, so as to ensure that there is operating space for the operator to manually drive the first screw 9 on the front side of the first wall 1. The cross-section of the mounting groove 5 is T-shaped. With this design, the mounting groove 5 includes a vertical groove 51 and a horizontal groove 52. The vertical groove 51 is perpendicular to and connected to the horizontal groove 52. The connecting component is installed in the horizontal groove 52. The cooperation structure of the first screw 9 and the first screw sleeve 10 drives the movement of the clamping plate 11 on the one hand, and provides a force point for the clamping plate 11 on the other hand.
[0030] The mounting frame 8 of the connecting component can be fixedly installed in the horizontal groove 52. At this time, the first end of the first screw 9 passes through the left side wall of the mounting frame 8 and abuts against the right inner side wall of the mounting frame 8. When the second protrusion 19 of the clamping plate 11 is engaged in the second clamping groove 7, this design provides a point of force for the clamping plate 11. The mounting frame 8 of the connecting component can be movably installed in the horizontal groove 52. A limiting block 20 is provided at the second end of the first screw 9. The limiting block 20 is located in the vertical groove 51. The vertical projection of the limiting block 20 in the vertical plane partially falls outside the vertical projection of the horizontal groove 52 in the vertical plane. The limiting block 20 abuts against the side wall of the vertical groove 51. When the second protrusion 19 of the clamping plate 11 is engaged in the second clamping groove 7, it provides a point of force for the clamping plate 11. With this design, the first end or the second end of the first screw 9 is provided with a limiting abutment to provide a point of force for the clamping plate 11, ensuring a firm connection between the first wall 1 and the second wall 2.
[0031] like Figure 1 As shown, the number of mounting slots 5 can be set to one or more, preferably two. The two mounting slots 5 are symmetrically arranged with the insert block 3 as the center. This ensures a firm connection, balanced force, and reduces costs.
[0032] like Figure 2 , Figure 3 and Figure 4As shown, the first threaded sleeve 10 has at least one first inclined surface 12 facing the right side of the mounting frame 8. One or more first inclined surfaces 12 can be provided. When there are two or more first inclined surfaces 12, the first inclined surfaces 12 are arranged in a ring around the central axis of the first threaded sleeve 10. At this time, two or more clamping plates 11 are correspondingly provided. The first inclined surface 12 is parallel to the second inclined surface 13 of the clamping plate 11. The first protrusion 17 of the clamping plate 11 cooperates with the guide groove 16. With this design, when the first screw 9 is rotated to push the clamping plate 11 to the right, the clamping plate 11 is displaced in a direction perpendicular to the pushing direction, so that the second protrusion 19 is engaged in the second groove 7. When the first screw 9 is rotated to retract the clamping plate 11 to the left, the second protrusion 19 is disengaged from the second groove 7. By providing multiple clamping plates 11 and using the second protrusion 19 of the clamping plate 11 to engage with the second groove 7, the connection between the first wall 1 and the second wall 2 is further strengthened.
[0033] like Figure 3 and Figure 4 As shown, preferably, the first threaded sleeve 10 has two first inclined surfaces 12, which are located on the front and rear sides of the first threaded sleeve 10, respectively. One first inclined surface 12 corresponds to one retaining plate 11, and one retaining plate 11 corresponds to one second retaining groove 7. The front inner wall and the rear inner wall of the mounting frame 8 are both provided with guide grooves 16. Rotating the first screw 9 drives the retaining plate 11 to be fed to the right. When the second protrusion 19 reaches the second retaining groove 7, one of the two retaining plates 11 is displaced in the forward direction, and the other retaining plate 11 is displaced in the rearward direction.
[0034] Regarding the setting of the width of the first slot 6, the width of the first slot 6 can be greater than or approximately equal to the width of the end of the card plate 11 with the second protrusion 19. "Approximately equal to" means that the width of the first slot 6 is slightly greater than (smaller fitting clearance) the width of the end of the card plate 11 with the second protrusion 19. When the width of the first slot 6 is greater than the width of the end of the card plate 11 with the second protrusion 19, since the card plate 11 has room to move in both the pushing direction and perpendicular to the pushing direction, the card plate 11 will be displaced in both the pushing direction and perpendicular to the pushing direction when entering the first slot 6, until the second protrusion 19... When the second card slot 7 is inserted into the first card slot 6, the card plate 11 will not wobble in the first card slot 6 due to the tight fit between the insert block 3 and the slot 4. When the width of the first card slot 6 is approximately equal to the width of the end of the card plate 11 with the second protrusion 19, the card plate 11 has room to move only in the pushing direction, while its movement is restricted in the direction perpendicular to the pushing direction. When the card plate 11 enters the first card slot 6, it only moves in the pushing direction until the second protrusion 19 reaches the second card slot 7. At this point, the card plate 11 moves in both the pushing direction and the direction perpendicular to the pushing direction, so that the second protrusion 19 is inserted into the second card slot 7.
[0035] like Figure 1As shown, furthermore, a sloping baffle 21 is provided on the front side of the first wall 1 above the mounting groove 5. The sloping baffle 21 can be used to shield rainwater and prevent rainwater from eroding the connecting components.
[0036] like Figure 1 As shown in the embodiment of this solution, a first connecting hook 22 is rotatably connected to the front side of the first wall 1, and a fixing block 23 is fixedly installed on the front side of the second wall 2. The second wall 2 also includes a second screw 24 and a second threaded sleeve 25. One end of the second screw 24 is fixedly connected to the fixing block 23, and the second threaded sleeve 25 is threadedly connected to the second screw 24. A second connecting hook 26 is rotatably connected to the end of the second threaded sleeve 25 away from the fixing block 23. The rotation axes of the second threaded sleeve 25 and the second connecting hook 26 are coaxial. Rotating the second threaded sleeve 25 moves the second connecting hook 26 to the right until the first connecting hook 22 and the second connecting hook 26 are connected and tightened. In addition to the internal connection between the first wall 1 and the second wall 2, an external connection structure is added to make the connection between the first wall 1 and the second wall 2 more stable.
[0037] The second threaded sleeve 25 is rotatably connected to the end away from the fixed block 23 with a second connecting hook 26. When the second threaded sleeve 25 is short, in order to avoid interference between the second screw 24 and the second connecting hook 26 during the rotation of the second threaded sleeve 25, a clearance groove can be opened on the second connecting hook 26. When the second threaded sleeve 25 is rotated, the second threaded sleeve 25 moves to the right, and the second screw 24 can be placed in the clearance groove after extending out of the second threaded sleeve 25. Alternatively, the second threaded sleeve 25 can be designed to be as long as possible, so that the second screw 24 moves inside the second threaded sleeve 25 without extending out of the second threaded sleeve 25, and the second screw 24 will not interfere with the movement of the second connecting hook 26.
