Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a prefabricated wall structure incorporating a self-locking structure. Background Technology

[0002] Prefabricated construction refers to a construction method in which some or all of the building components are manufactured in a prefabrication plant, then transported to the construction site by appropriate means of transportation, and assembled using reliable installation methods and machinery to become a functional building.

[0003] Existing prefabricated wall structures incorporating self-locking mechanisms can be referenced in Chinese Invention Patent No. CN201910765870.0, which discloses a prefabricated wall structure incorporating a self-locking mechanism. "It is assembled from prefabricated wall panels. A corner stabilizing device is provided between two prefabricated wall panels at a corner. The corner stabilizing device includes a first angle steel, a second angle steel, and a connecting plate disposed between the first and second angle steels. One end of the connecting plate is fixedly connected to the first angle steel, and the other end is fixedly connected to the second angle steel. The connecting plate divides the first and second angle steels into two installation spaces. A sliding groove is provided on the connecting plate, which is arranged along the direction close to the first angle steel.

Both ends of the slider are provided with a clamping plate for pressing the prefabricated wall panel to the first angle steel. This utility model has the advantages of stable connection and easy angle control."

[0004] However, due to the updating of modern building design concepts, adjacent prefabricated wall panels are assembled at different angles. In the above building structure, it is not possible to achieve large-angle assembly between adjacent prefabricated wall panels. Therefore, a prefabricated wall structure combined with a self-locking structure is proposed. Utility Model Content

[0006] This utility model provides the following technical solution: a prefabricated wall structure with a self-locking structure, including two sets of walls arranged opposite to each other, and a horizontal adjustment component disposed on the outer wall of the opposite surface of the two sets of walls. An angle adjustment component is disposed on the inner wall of the opposite surface of the two sets of horizontal adjustment components, and a connecting shaft is disposed at the opposite end of the two sets of angle adjustment components.

[0007] As a preferred technical solution of this utility model: the horizontal adjustment component includes a connecting plate, a supporting connecting tube is fixedly assembled on the bottom outer wall of the connecting plate near the connecting shaft, a rotating groove is opened on the top outer wall of the connecting plate corresponding to the supporting connecting tube, a connecting shaft is rotatably sleeved on the inner wall of the supporting connecting tube, an inlay groove is opened on the outer wall of the connecting plate near the connecting shaft, and an external hexagonal nut is rotatably sleeved on the inner wall of the inlay groove.

[0008] As a preferred technical solution of this utility model: the inner wall of the external hexagonal nut is provided with an internal thread, and the outer wall of the external hexagonal nut near the connecting shaft is provided with an external hexagonal groove.

[0009] As a preferred technical solution of this utility model: the horizontal adjustment assembly further includes a horizontal plate disposed on the side of the connecting plate near the wall. The outer wall of the horizontal plate near the connecting plate has a first movable groove. The outer wall of the first movable groove is fixedly fitted with a fixing plate by bolts. The outer wall of the fixing plate has two second movable grooves. The inner wall of the second movable groove is provided with an external threaded rod. The outer wall of the external threaded rod near the first movable groove is fixedly fitted with a limiting circular plate. The outer wall of the horizontal plate near the wall is fixedly fitted with several J-shaped rods.

[0010] As a preferred technical solution of this utility model: the opposite surfaces of the moving groove and the fixed plate are provided with a plurality of protrusions, and the opposite surfaces of the limiting circular plate, the fixed plate and the moving groove are provided with a plurality of protrusions.

[0011] As a preferred technical solution of this utility model: the diameter of the external threaded rod is smaller than the diameter of the second movable groove, the diameter of the second movable groove is smaller than the diameter of the limiting circular plate, and the limiting circular plate can move within the inner wall of the first movable groove.

[0012] As a preferred technical solution of this utility model: the angle adjustment component includes a rotating shaft tube, a rotating shaft rotatably connected to the rotating shaft tube is inlaid on the outer wall of the same side of the rotating shaft tube, a limiting rotating block is threadedly connected to the outer edge of the rotating shaft, a sleeve groove is formed through the top outer wall of the limiting rotating block, an internal thread groove is formed along the axial direction of the rotating shaft, an internal thread limiting groove is formed on the outer wall of the limiting rotating block and communicates with the inner wall of the sleeve groove, and a limiting bolt is threadedly connected to the inner wall of the internal thread limiting groove.

[0013] As a preferred technical solution of this utility model: the rotating shaft tubes of the two sets of angle adjustment components are set at the rotating groove and are sleeved with the sleeve shaft. The positions of the rotating shafts in the two sets of angle adjustment components are staggered vertically. The limiting rotating blocks in the two sets of angle adjustment components are rotatably connected to the outer edge of the connecting shaft.

[0014] This utility model has the following beneficial effects:

[0015] 1. This prefabricated wall structure with a self-locking mechanism uses a J-shaped rod to connect the horizontal plate to the wall. An external threaded rod moves a limiting circular plate within the cavity formed by the fixed plate and the moving groove. When the horizontal plate is not level with the outer wall, the extra space provided by the limiting circular plate within the moving groove and the fixed plate allows the external threaded rod to correspond to the inner wall of the external hexagonal nut. The outer wall of the external hexagonal nut near the connecting shaft has an external hexagonal groove, allowing it to be rotated with an internal hexagonal wrench. The internal thread on the inner wall of the external hexagonal nut allows it to be threadedly connected to the external threaded rod. By changing the positions of the four external hexagonal nuts and four external threaded rods, the horizontal alignment between the connecting plate and the wall can be achieved.

[0016] 2. This prefabricated wall structure with a self-locking structure fixes the angle between the two sets of walls by rotating the limiting block in the angle adjustment component connected to the two sets of horizontal adjustment components, and by rotating the limiting bolt connected to the inner wall of the internal thread limiting groove, the limiting bolt and the connecting shaft abut together. The angle between the two sets of walls can be changed by rotating the connecting shaft to connect the two sets of walls.

[0017] 3. This prefabricated wall structure with a self-locking mechanism changes the position of the limiting block on the outer wall of the rotating shaft by rotating the rotating shaft, thereby changing the distance between the connecting shaft and the connecting plate. By rotating the two sets of angle adjustment components respectively, the positions of the limiting block and the rotating shaft in the two sets of angle adjustment components are different, thereby achieving the left and right offset of the connecting shaft on the plane of the connecting plate. This allows the distance between the two sets of walls and the connecting shaft to be changed by changing the position of the limiting block, thereby achieving the adjustment of the rotation angle of the two sets of walls through the connecting shaft. This solves the problem in the prior art that large-angle assembly between adjacent prefabricated wall panels cannot be achieved. Attached Figure Description

[0036] In a preferred embodiment: the inner wall of the external hexagonal nut 406 is provided with an internal thread, and the outer wall of the external hexagonal nut 406 near the connecting shaft 2 is provided with an external hexagonal groove.

[0037] In the above structure, by opening a rotating groove 403 and setting the sleeve shaft 404 on the inner wall of the support connecting tube 402, the connecting part of the angle adjustment component 3 and the horizontal adjustment component 4 can be connected to the horizontal adjustment component 4 and the rotating shaft tube 301 through the sleeve shaft 404. By rotating the external hexagonal nut 406 onto the inner wall of the inlay groove 405, the external hexagonal nut 406 has an external hexagonal groove on the outer wall of the end near the connecting shaft 2, so that the external hexagonal nut 406 can be rotated by an existing internal hexagonal wrench. The internal thread is provided on the inner wall of the external hexagonal nut 406, so that the external hexagonal nut 406 can be threadedly connected to the external thread rod 4013.

[0038] In a preferred embodiment: the horizontal adjustment assembly 4 further includes a horizontal plate 407 disposed on the side of the connecting plate 401 near the wall 1. The outer wall of the horizontal plate 407 near the connecting plate 401 is provided with a first moving groove 408. The outer wall of the first moving groove 408 is fixedly mounted with a fixed plate 409 by bolts. The outer wall of the fixed plate 409 is provided with two second moving grooves 4010. The inner wall of the second moving groove 4010 is provided with an external threaded rod 4013. The outer wall of the external threaded rod 4013 near the first moving groove 408 is fixedly mounted with a limiting circular plate 4011. The outer wall of the horizontal plate 407 near the wall 1 is fixedly mounted with a plurality of J-shaped rods 4012.

[0039] In a preferred embodiment: the opposing surfaces of the movable groove 408 and the fixed plate 409 are provided with a plurality of protrusions, and the opposing surfaces of the limiting circular plate 4011, the fixed plate 409, and the movable groove 408 are provided with a plurality of protrusions.

[0040] By setting the protrusion, after the limiting circular plate 4011 and the internal thread limiting groove 306 are fixed, the connecting plate 401 and the horizontal plate 407 are attached to each other, thereby pulling the limiting circular plate 4011 to the side of the connecting plate 401, so that the limiting circular plate 4011 and the fixing plate 409 are fixed by the protrusion.

The diameter of the external threaded rod 4013 is smaller than the diameter of the second moving groove 4010, and the diameter of the second moving groove 4010 is smaller than the diameter of the limiting circular plate 4011. The limiting circular plate 4011 can move within the inner wall of the first moving groove 408, allowing the external threaded rod 4013 to drive the limiting circular plate 4011 to move within the cavity formed by the fixed plate 409 and the first moving groove 408, thereby allowing the horizontal plate 407 to connect with the wall 1. When the outer wall of wall 1 is not level, the extra space for the limiting circular plate 4011 to move within the inner wall formed by the moving groove 408 and the fixed plate 409 can be used to achieve the correspondence between the inner wall of the external thread rod 4013 and the external hexagonal nut 406. Then, by rotating the external hexagonal nut 406, the external hexagonal nut 406 and the external thread rod 4013 can be threaded together. By changing the position of the threaded connection between the four external hexagonal nuts 406 and the four external thread rods 4013, the horizontal adjustment between the connecting plate 401 and wall 1 can be achieved.

[0043] In a preferred embodiment: the angle adjustment assembly 3 includes a rotating shaft tube 301, a rotating shaft 302 rotatably connected to the rotating shaft tube 301 is inlaid on the outer wall of the same side of the rotating shaft tube 301, a limiting rotating block 303 is threadedly connected to the outer edge of the rotating shaft 302, a sleeve groove 304 is provided through the top outer wall of the limiting rotating block 303, an internal thread groove 305 is provided along the axial direction of the rotating shaft 302, an internal thread limiting groove 306 is provided on the outer wall of the limiting rotating block 303 and communicates with the inner wall of the sleeve groove 304, a limiting bolt is threadedly connected to the inner wall of the internal thread limiting groove 306, and the rotating shaft 302 is threadedly connected to the limiting rotating block 303 through the internal thread groove 305;

[0044] An internal hexagonal groove is provided on the end of the rotating shaft 302 away from the rotating shaft tube 301;

[0045] In a preferred embodiment: the rotating shaft tubes 301 of the two sets of angle adjustment components 3 are disposed at the rotating groove 403 and are sleeved with the sleeve shaft 404. The positions of the rotating shafts 302 in the two sets of angle adjustment components 3 are staggered vertically. The limiting rotating blocks 303 in the two sets of angle adjustment components 3 are rotatably connected to the outer edge of the connecting shaft 2.

[0046] In the above structure, two sets of rotating shaft tubes 301 are rotatably connected to the connecting plate 401 via a sleeve shaft 404. The connecting shaft 2 rotatably connects the limiting rotating blocks 303 in the two sets of angle adjustment components 3, forming a triangular arrangement between the horizontal adjustment component 4 and the connecting shaft 2 via the two sets of angle adjustment components 3. The rotating shaft 302 is rotatably connected to the rotating shaft tubes 301 via a rotating sleeve. The rotating shaft 302 is threadedly connected to the limiting rotating block 303 via an internal thread groove 305. The connecting shaft 2 is rotatably connected to the limiting rotating block 303 via a sleeve groove 304, allowing personnel to rotate the rotating shaft. 302. Change the position of the limiting block 303 on the outer wall of the rotating shaft 302, thereby changing the distance between the connecting shaft 2 and the connecting plate 401. By rotating the two sets of angle adjustment components 3 respectively, the positions of the limiting block 303 and the rotating shaft 302 in the two sets of angle adjustment components 3 are different, thereby achieving the left and right offset of the connecting shaft 2 on the plane of the connecting plate 401. The limiting bolt connected by the inner thread of the internal thread limiting groove 306 is rotated to make the limiting bolt and the connecting shaft 2 abut against each other, thereby fixing the connecting shaft 2 and the limiting block 303.

[0047] Working principle: By setting a J-shaped rod 4012, the horizontal plate 407 is connected to the wall 1 through the J-shaped rod 4012. The external threaded rod 4013 can drive the limiting circular plate 4011 to move within the cavity formed by the fixed plate 409 and the moving groove 408. This allows the external threaded rod 4013 to move within the extra space of the limiting circular plate 4011 within the cavity formed by the moving groove 408 and the fixed plate 409 when the horizontal plate 407 is not horizontally connected to the outer wall of the wall 1. Corresponding to the inner wall of the external hexagonal nut 406, the outer wall of the external hexagonal nut 406 near the connecting shaft 2 is provided with an external hexagonal groove, so that the external hexagonal nut 406 can be rotated by an existing internal hexagonal wrench. The internal thread provided on the inner wall of the external hexagonal nut 406 allows the external hexagonal nut 406 to be threadedly connected with the external threaded rod 4013. By changing the position of the threaded connection between the four external hexagonal nuts 406 and the four external threaded rods 4013, the horizontal adjustment between the connecting plate 401 and the wall 1 can be achieved.

[0048] Two sets of rotating shaft tubes 301 are rotatably connected by sleeve shaft 404 and connecting plate 401, and the limiting rotating block 303 in the two sets of angle adjustment components 3 is rotatably sleeved by connecting shaft 2, so that the horizontal adjustment component 4 and the connecting shaft 2 form a triangular arrangement through the two sets of angle adjustment components 3;

[0049] The rotating shaft 302 and the rotating shaft tube 301 are rotatably connected. The rotating shaft 302 is threadedly connected to the limiting rotating block 303 through the internal thread groove 305. The connecting shaft 2 is rotatably connected to the limiting rotating block 303 through the sleeve groove 304. This allows personnel to change the position of the limiting rotating block 303 on the outer wall of the rotating shaft 302 by rotating the rotating shaft 302, thereby changing the distance between the connecting shaft 2 and the connecting plate 401. By rotating the two sets of angle adjustment components 3 respectively, the positions of the limiting rotating block 303 and the rotating shaft 302 in the two sets of angle adjustment components 3 are different, thereby achieving the left and right offset of the connecting shaft 2 on the plane of the connecting plate 401. This allows the distance between the two sets of walls 1 and the connecting shaft 2 to be changed by changing the position of the limiting rotating block 303, thereby adjusting the rotation angle of the two sets of walls 1 through the connecting shaft 2.

[0050] By symmetrically and oppositely setting the horizontal adjustment components 4 on the outer walls of the two walls 1, the two sets of angle adjustment components 3 connected to the two sets of horizontal adjustment components 4 are set up vertically. The limiting rotating block 303 in the two sets of angle adjustment components 3 is rotated and sleeved by the connecting shaft 2, so that the two sets of walls 1 are rotatably connected through the angle adjustment components 3 and the horizontal adjustment components 4.

[0051] The rotating shaft 302 and the rotating shaft tube 301 are rotatably connected. The rotating shaft 302 is threadedly connected to the limiting rotating block 303 through the internal thread groove 305. The connecting shaft 2 is rotatably connected to the limiting rotating block 303 through the sleeve groove 304. This allows the operator to change the position of the limiting rotating block 303 on the outer wall of the rotating shaft 302 by rotating the rotating shaft 302, thereby changing the distance between the connecting shaft 2 and the connecting plate 401. By rotating the two sets of angle adjustment components 3 respectively, the positions of the limiting rotating block 303 and the rotating shaft 302 in the two sets of angle adjustment components 3 are different, thereby achieving the left and right offset of the connecting shaft 2 on the plane of the connecting plate 401. The limiting bolt is threadedly connected to the inner wall of the internal thread limiting groove 306. By rotating the limiting bolt, the limiting bolt and the connecting shaft 2 abut against each other, thereby fixing the diameter of the connecting shaft 2 and the limiting rotating block 303.

[0052] By rotating the limiting block 303 in the angle adjustment component 3 connected to the two sets of horizontal adjustment components 4, and rotating the limiting bolt connected to the inner wall thread of the internal thread limiting groove 306, the limiting bolt and the connecting shaft 2 are brought into contact, thereby fixing the angle between the two sets of walls 1.
