Description

Technical Field

[0001] This invention relates to a multi-story prefabricated steel structure wall panel, and particularly to a multi-story prefabricated steel structure wall panel applicable to the field of prefabricated steel structure wall panels. Background Technology

[0002] Multi-story prefabricated steel structure wall panels can assist in the prefabricated construction of buildings, thereby shortening construction costs and accelerating construction progress. When existing steel structure wall panels are assembled on the construction site, they are either fitted with slots or locked with bolts. However, the connection between adjacent wall panels cannot ensure firmness, which affects the reliability of the assembled wall panels during use.

[0003] To address the issue of wall panel assembly stability, a certain prefabricated steel structure wall panel on the market adopts a boltless fastening assembly design, which has a certain market share.

[0004] Chinese invention patent CN202211112544.8 discloses a low-energy prefabricated steel structure residential composite wall panel, including a wall panel. A first connecting block is fixedly installed at the bottom of the wall panel, and a second connecting cavity is formed at the top of the wall panel. A second connecting block is movably installed inside the second connecting cavity. A first connecting cavity is formed on the left side of the wall panel, and a third connecting block is fixedly installed on the right side of the wall panel. A rotating column is movably installed inside the wall panel, and a gear is fixedly installed at the tail end of the rotating column. This invention connects two adjacent wall panels together, and the two adjacent wall panels cooperate with each other through a connecting mechanism. The connection between the two wall panels is tight, and the installation between adjacent wall panels is convenient. Connecting two adjacent wall panels is simple, convenient, and quick, and does not require excessive tools for chiseling the wall, effectively preventing dust generation and achieving a better environment.

[0005] Although the use of screws is reduced during the assembly of the prefabricated steel structure wall panels, the rectangular design of the wall panels makes it easy to create dead corners when splicing at right angles, which can become areas for dust accumulation and are difficult to clean. In addition, the prefabricated steel structure wall panels use a large number of auxiliary parts during the overall assembly process, which is inconvenient to operate. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to ensure the firmness of the assembly between adjacent wall panels, avoid the occurrence of assembly dead corners, and simplify the assembly process.

[0007] To address the aforementioned problems, this invention provides a multi-story prefabricated steel structure wall panel, comprising a No. 1 panel and a No. 2 panel. Both No. 1 and No. 2 panels have isosceles trapezoidal cross-sections. Both sides of the No. 1 panel are provided with internal slots. One side of the No. 2 panel is provided with an insertion slot and a branch slot arranged perpendicular to the insertion slot. A cavity is arranged on the side of the No. 2 panel away from the insertion slot. A gear and a rack located below the gear and meshing with the gear are installed inside the cavity. An insertion strip is connected to the end of the rack near the No. 1 panel and penetrates the No. 2 panel. The insertion strip is engaged with the branch slot, the insertion slot, and the internal slot. An internal rotating rod is installed through the gear. A receiving screw is threaded into the internal rotating rod. A special-shaped wedge is installed on the outer side of the receiving screw.

[0008] In the above-mentioned multi-story prefabricated steel structure wall panels, by using the No. 1 and No. 2 panels with a cross-section that can be spliced ​​into isosceles trapezoids, the generation of splicing dead corners can be avoided when splicing the vertical corners of the wall panels. At the same time, when splicing horizontally, vertical constraints can be applied simultaneously, making the splicing process of this invention labor-saving and convenient.

[0009] As a further improvement of this application, a circular plate is inlaid on the top of the irregular wedge, and a through channel is provided on the surface of the second plate, and the through channel matches both the irregular wedge and the circular plate.

[0010] As a further improvement of this application, the irregular wedge has a storage cavity inside, and a retaining strip with a length equal to the length of the retaining screw is fixedly wrapped around the surface of the end of the retaining screw near the storage cavity. The retaining strip is slidably fitted and connected to the inner wall of the storage cavity, and the retaining strip is engaged with the inner wall of the inner rotating rod.

[0011] As a further improvement of this application, the rear wall of the cavity is provided with a sliding track, and the tail end of the inner rotating rod is slidably connected to the inside of the sliding track.

[0012] As a further improvement of this application, the length of the receiving screw is greater than the length of the receiving cavity, and the distance between the outer surface of the irregular wedge and the tail end of the receiving screw in the receiving state is equal to the distance between the outer surface of the irregular wedge and the surface of the gear.

[0013] As a further improvement of this application, the tail end of the sliding track is located above the rack in the initial state, and the bottom projection of the through channel is located on the surface of the gear.

[0014] As another improvement of this application, both Plate 1 and Plate 2 are equipped with inner constraint rails. The lower half of the inner constraint rails is provided with through grooves that match the inserts. A limit bracket is installed on the inner wall of the inner constraint rails near the top. A magnetic insert with a cross-sectional area larger than the limit bracket is placed on the top surface of the limit bracket. The end surface of the insert is coated with a magnetic coating that repels the magnetic insert. Both Plate 1 and Plate 2 are provided with constraint grooves on the same vertical axis as the magnetic inserts near the bottom.

[0015] As a further improvement to this application, the magnetic insert is slidably connected to the inside of the constraint inner rail, and the length of the magnetic insert is equal to the distance between the limit bracket and the top of the constraint inner rail.

[0016] In summary, this invention utilizes plates number one and number two, with cross-sections of isosceles trapezoids that can be spliced ​​together. This allows for full utilization of space and avoids dead corners when splicing wall panels at vertical corners. Simultaneously, during horizontal splicing, the irregularly shaped wedges drive the storage screw to rotate, which in turn drives the gear to rotate. The meshing action between the gear and rack then facilitates the smooth movement of the insert into adjacent slots, inner slots, or insertion grooves, forming a secure splicing and locking mechanism. Furthermore, the horizontal insertion action of the insert can support the vertical magnetic insert, thus creating a vertical connection and locking effect for the wall panels. This makes splicing this invention labor-saving and convenient. Attached Figure Description

[0030] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] Implementation method 1:

[0032] Figures 1-8 A multi-story prefabricated steel structure wall panel is shown, including a No. 1 panel 1 and a No. 2 panel 2. The cross-section of the No. 1 panel 1 and the No. 2 panel 2 is an isosceles trapezoid. Both sides of the No. 1 panel 1 are provided with inner slots 11. One side of the No. 2 panel 2 is provided with a plug groove 21 and a branch groove 22 arranged perpendicular to the plug groove 21. A cavity is arranged on the side of the No. 2 panel 2 away from the plug groove 21. A gear 32 and a rack 33 located below the gear 32 and meshing with the gear 32 are installed inside the cavity. The end of the rack 33 near the No. 1 panel 1 is connected to a plug 34 that passes through the No. 2 panel 2. The plug 34 is engaged with the branch groove 22, the plug groove 21 and the inner slot 11. An inner rotating rod 31 is installed through the inside of the gear 32. The inner rotating rod 31 is threadedly connected to a receiving screw 36. A special-shaped wedge 3 is installed on the outside of the receiving screw 36.

[0033] The top of the irregular wedge 3 is inlaid with a circular plate, and the surface of the second plate 2 is provided with a through channel 35, which matches both the irregular wedge 3 and the circular plate.

[0034] The irregular wedge 3 has a storage cavity inside. The surface of the storage screw 36 near the storage cavity is surrounded by a snap-fit ​​strip 361 with a length equal to the length of the storage screw 36 itself. The snap-fit ​​strip 361 is slidably fitted into the inner wall of the storage cavity and snaps into the inner wall of the inner rotating rod 31.

[0035] The rear wall of the cavity is provided with a sliding track, and the tail end of the inner rotating rod 31 is slidably connected to the inside of the sliding track;

[0036] The length of the receiving screw 36 is greater than the length of the receiving cavity, and the distance between the outer surface of the irregular wedge 3 and the tail end of the receiving screw 36 in the receiving state is equal to the distance between the outer surface of the irregular wedge 3 and the surface of the gear 32.

[0037] The tail end of the sliding track is located above the rack 33 in the initial state, and the bottom projection of the through channel 35 is located on the surface of the gear 32.

[0038] Specifically, the cross sections of Plate 1 and Plate 2 can be spliced ​​together to form a seamless wall panel. Then, the irregular wedge 3 is pulled out of the interior of Plate 2, and the receiving screw 36 is pulled out and inserted into the circular part of the through channel 35 until the end of the receiving screw 36 is inserted into the interior of the inner rotating rod 31 and continues to rotate, driving the inner rotating rod 31 and the gear 32 fixedly connected to the inner rotating rod 31 to rotate. Under the action of meshing transmission, the rack 33 moves to drive the insert 34 to extend out of the interior of Plate 2 and into the inner slot 11 on the surface of Plate 1, strengthening the splicing firmness between Plate 1 and Plate 2.

[0039] Afterwards, the storage screw 36 is pulled out of the inner rotating rod 31 and pushed into the storage cavity. Then, the irregular wedge 3 is pushed into the through channel 35. As the irregular wedge 3 goes deeper, the slope of its surface will gradually push the inner rotating rod 31 up, thereby driving the gear 32 to rise and disengage from the rack 33. This can effectively prevent the rotation of the inner rotating rod 31 in an unnecessary state, maintain the connection between the insert 34 and the first plate 1. At the same time, in this state, the irregular wedge 3 forms a filling treatment on the surface of the second plate 2, which can ensure the flatness of the surface of the second plate 2. It can also be used as a tool on the spot during assembly and disassembly, which is convenient for operation.

[0040] Furthermore, when vertically splicing wall panels, the present invention can splice two No. 2 panels 2 together. During this process, the insert 34 extending from the inside of one of the No. 2 panels 2 enters the slot 22, thus successfully completing the firm splicing and locking between adjacent No. 2 panels 2. The vertical wall panel part formed by splicing in this state does not form dead corners compared with the existing technology of direct overlapping operation, and occupies less indoor space.

[0041] The second implementation method:

[0042] Figures 9-11As shown, components that are the same as or corresponding to those in the first embodiment are represented by reference numerals corresponding to those in the first embodiment. For simplicity, only the differences from the first embodiment will be described below. The difference between this second embodiment and the first embodiment is that: both plate 1 and plate 2 are equipped with inner constraint rails 4. The lower half of the inner constraint rails 4 is provided with a through groove that matches the insert 34. A limit bracket 41 is installed on the inner wall of the inner constraint rails 4 near the top. A magnetic insert 42 with a cross-sectional area larger than the limit bracket 41 is placed on the top surface of the limit bracket 41. The end surface of the insert 34 is coated with a magnetically attracted coating that repels the magnetic insert 42. Both plate 1 and plate 2 are provided with constraint grooves 5 near the bottom, which are on the same vertical axis as the magnetic insert 42.

[0043] The magnetic insert 42 is slidably connected to the inside of the inner constraint rail 4, and the length of the magnetic insert 42 is equal to the distance between the limiting bracket 41 and the top of the inner constraint rail 4.

[0044] Specifically, during vertical splicing, as the insert 34 enters the inner slot 11 or the fork slot 22, under the action of magnetic repulsion, the magnetic insert 42, which was originally placed on the surface of the limiting bracket 41, moves upward and inserts into the constraint slot 5 inside the first plate 1 or the second plate 2 above, making it stable and secure.

[0045] Furthermore, when it is necessary to disassemble or assemble the wall constructed by the present invention, the irregular wedge 3 is removed, and the lifting effect of the irregular wedge 3 is lost. The gear 32 falls and continues to mesh with the rack 33. Then, the receiving screw 36 is inserted into the inner rotating rod 31 and rotated in the opposite direction, thereby removing the insert 34 from the inside of the first plate 1. At this time, the magnetic insert 42 is disengaged from the inside of the constraint groove 5, and the horizontal and vertical disassembly operations can be completed simultaneously, making the disassembly and assembly of the present invention more convenient.

[0046] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
