Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustment component for assembling precast shear walls. Background Technology

[0002] Precast shear walls are concrete walls pre-cast in a factory. After being transported to the construction site, they are connected to the main structure or other precast components using reliable connection methods, ultimately forming a unified load-bearing structural system. Factory production ensures the stability and uniformity of shear wall quality, reduces the impact of human factors on construction quality, and ensures high dimensional accuracy of components. With much of the work completed in the factory, only hoisting and connection operations are required on-site, significantly reducing wet work on the construction site, shortening the construction period, and improving construction efficiency.

[0003] During the installation of precast shear walls, it is necessary to adjust the planar position of the precast shear walls. At this time, the construction workers will use two diagonal braces to make horizontal displacement of the precast shear walls. One diagonal brace will be connected to the high point of the precast shear wall to ensure that the precast shear wall does not deform too much during adjustment, and the other will be connected to the low point of the precast shear wall to ensure that the diagonal brace has a sufficient adjustment angle.

[0004] However, when it is necessary to adjust the horizontal position between precast shear walls, there is no good way to adjust and control the horizontal position of the precast shear walls. This will result in the vertical gaps between the precast shear walls not being straight enough, resulting in poor wall quality after construction and inability to guarantee safety.

[0005] To address the above shortcomings, a structural device is needed to adjust the horizontal position of precast shear walls, thereby improving the problem of uneven vertical gaps caused by the inability to adjust the horizontal position of precast shear walls. Utility Model Content

[0006] This invention aims to overcome the problem that vertical gaps in precast shear walls are not straight due to the inability to adjust the horizontal position, and provides an adjustment component for assembling precast shear walls.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustment assembly for assembling a precast shear wall, comprising a first connecting plate located on one precast shear wall and a second connecting plate located on another precast shear wall, an adjustment assembly being provided between the first connecting plate and the second connecting plate, the first connecting plate being movably connected to the adjustment assembly, and the first connecting plate being able to move the precast shear wall to which it is connected away from or closer to the second connecting plate.

[0008] As a further embodiment of this utility model: the adjustment component includes a connecting rod, the two ends of which are respectively connected to the first connecting plate and the second connecting plate to form a movable connection.

[0009] As a further embodiment of this utility model: the first connecting plate is provided with a fixing member, and the end of the connecting rod near the first connecting plate is connected to the fixing member, and the fixing member is fastened to the first connecting plate.

[0010] As a further embodiment of this utility model: the second connecting plate is provided with a sleeve, the surface of the connecting rod is provided with threads, and the sleeve is threadedly connected to one end of the connecting rod near the second connecting plate.

[0011] As a further embodiment of this utility model: both sides of the first connecting plate are connected to a first side plate, and the first side plate is provided with a strip groove for accommodating the connecting rod. The fixing member is located on both sides of the first side plate and abuts against the first side plate.

[0012] As a further embodiment of this utility model: both sides of the second connecting plate are connected to second side plates, and the second side plates are provided with through holes for the connecting rod to pass through. The sleeve is located between the two second side plates and corresponds to the position of the through holes.

[0013] As a further embodiment of this utility model: the fixing member is two abutment plates located on two first side plates respectively.

[0014] As a further embodiment of this utility model: the sleeve is a threaded sleeve, which is connected to the sidewalls of the two second side plates that are close to each other.

[0015] As a further embodiment of this utility model: the end of the connecting rod near the threaded sleeve is provided with a thread, and the threaded end of the connecting rod is located inside the threaded sleeve.

[0016] As a further embodiment of this utility model: both the first connecting plate and the second connecting plate are provided with bolt sleeves for connecting with the precast shear wall.

[0017] Compared with the prior art, the beneficial effects of this technical solution are as follows: the adjustment component can drive the precast shear wall to move away from or closer to the second connecting plate through the first connecting plate, thereby adjusting the horizontal position between the two precast shear walls and avoiding the situation where the vertical gap between the two precast shear walls is not straight.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7An adjustment assembly for assembling precast shear walls includes a first connecting plate 2 located on one precast shear wall 1 and a second connecting plate 3 located on another fixed precast shear wall 1. An adjustment assembly 4 is provided between the first connecting plate 2 and the second connecting plate 3. The first connecting plate 2 and the adjustment assembly 4 form a movable connection. The first connecting plate 2 can move the precast shear wall 1 it is connected to away from or closer to the second connecting plate 3. When the first connecting plate 2 moves, the second connecting plate 3 does not move, so that the second connecting plate 3 serves as the moving base of the first connecting plate 2, allowing the first connecting plate 2 to move horizontally relative to the second connecting plate 3 normally. Bolt sleeves 5 are provided on the side of the first connecting plate 2 and the second connecting plate 3 near the precast shear wall 1. The first connecting plate 2 and the second connecting plate 3 are fixed to their respective precast shear walls 1 by bolt sleeves 5. The two ends of the adjusting component 4 are respectively connected to the first connecting plate 2 and the second connecting plate 3. The connection between the first connecting plate 2 and the adjusting component 4 is a movable connection that can slide along a specific axis. When the adjusting component 4 starts to move, the adjusting component 4 can move the first connecting plate 2 and the precast shear wall 1 connected to it in a horizontal direction relative to the second connecting plate 3 and the corresponding precast shear wall 1, moving away from or closer to it.

[0023] Specifically, a hydraulic cylinder 6 is provided at the lower part of the first connecting plate 2 and the second connecting plate 3. The hydraulic cylinder 6 can lift the first connecting plate 2 and the second connecting plate 3, thereby causing the precast shear wall 1 connected to the first connecting plate 2 and the second connecting plate 3 to be suspended in the air, so as to achieve the purpose of the precast shear wall 1 being able to move in the horizontal direction.

[0024] In some embodiments: the adjusting component 4 includes a connecting rod 41, with both ends of the connecting rod 41 passing through the first connecting plate 2 and the second connecting plate 3 respectively to form a movable connection. The connecting rod 41 is a rigid rod body, with one end of the connecting rod 41 passing through the first connecting plate 2 and the other end passing through the second connecting plate 3. The first connecting plate 2 is provided with a fixing member 21, and the end of the connecting rod 41 near the first connecting plate 2 is connected to the fixing member 21. The fixing member 21 is fixed to the first connecting plate 2 and is adapted to the first side plate 22. The end of the connecting rod 41 near the first connecting plate 2 forms a rigid connection with the fixing member 21. The fixing of the fixing member 21 and the first side plate 22 can ensure that there is no relative displacement between the fixing member 21 and the first connecting plate 2, so that when the connecting rod 41 moves the fixing member 21, the force of the connecting rod 41 can be transmitted to the first connecting plate 2 through the fixing member 21, thereby moving the first connecting rod 2 and thus moving the precast shear wall 1.

[0025] Specifically: The second connecting plate 3 is provided with a sleeve 31, and the surface of the connecting rod 41 is threaded. The sleeve 31 is threadedly connected to the end of the connecting rod 41 near the second connecting plate 3. The sleeve 31 is fixedly disposed between the two second side plates 32 of the second connecting plate 3, and has internal threads. The outer surface of the end of the connecting rod 41 near the second connecting plate 3 is machined with external threads. The thread parameters of the two are matched, and the connection is achieved by thread engagement. The threaded connection allows the connecting rod 41 to move axially when it rotates relative to the sleeve 31, thereby causing the first connecting plate 2 to move away from or closer to the second connecting plate 3.

[0026] Furthermore: Both sides of the first connecting plate 2 are connected to the first side plate 22. The first side plate 22 is provided with a strip groove 23 for accommodating the connecting rod 41. The fixing member 21 is located on both sides of the first side plate 22. The fixing member 21 abuts against the first side plate 22. The fixing member 21 consists of two independent parts. The two fixing members 21 are located on the two sides of the two first side plates 22 that are far apart from each other. The two fixing members 21 are tightly abutted against the two first side plates 22 respectively. In this way, when the connecting rod 41 moves the first connecting plate 2 relatively away from or relatively close to the second connecting plate 3, the fixing member 21 can always abut against the first side plate 22, so that the connecting rod 41 can move the first connecting plate 2 relatively.

[0027] Optionally, a second side plate 32 is connected to both sides of the second connecting plate 3. The second side plate 32 has a through hole 33 for the connecting rod 41 to pass through. The sleeve 31 is located between the two second side plates 32 and corresponds to the position of the through hole 33. The second side plates 32 are vertically connected to the two sides of the second connecting plate 3 and are symmetrically distributed. The through hole 33 is opened at the center of the second side plate 32. The axis of the through hole 33 coincides with the axis of the sleeve 31, and the diameter of the through hole 33 is slightly larger than the diameter of the connecting rod 41, so that the connecting rod 41 can pass through the through hole 33 and enter the sleeve 31. The connecting rod 41 thus forms a threaded connection with the sleeve 31. Moreover, the two ends of the sleeve 31 are fixedly connected to the side of the two second side plates 32 that are close to each other, so that the position of the sleeve 31 can correspond to the position of the through hole 33, allowing the connecting rod 41 to pass through the through hole 33 and enter the sleeve 31.

[0028] Furthermore: the end of the connecting rod 41 near the threaded sleeve 311 is threaded, and the threaded end of the connecting rod 41 is located inside the threaded sleeve 311. The fixing member 21 consists of two abutment plates 211 located on the two first side plates 22 respectively. The sleeve 31 is the threaded sleeve 311, which is connected to the side walls of the two second side plates 32 that are close to each other. The threaded sleeve 311 is a cylindrical structure with open ends. The outer circular surface of the threaded sleeve 311 is fixedly connected to the side of the two second side plates 32 that are close to each other. The inner hole of the threaded sleeve 311 is machined with an internal thread that matches the external thread of the connecting rod 41. The fixed connection ensures that the threaded sleeve 311 will not be displaced when the connecting rod 41 rotates, so that the connecting rod 41 can move axially through the threaded transmission.

[0029] In other embodiments: the connecting rod 41 can be a double-ended screw with both positive and negative threads, and both precast shear walls 1 can move. The fixing member 21 is a nut. When the connecting rod 41 starts to rotate, the connecting rod 41 can make the first connecting plate 2 and the second connecting plate 3 move simultaneously by engaging with the nut and the threaded sleeve 311. Because the connecting rod 41 is a double-ended screw with both positive and negative threads, the first connecting plate 2 and the second connecting plate 3 move in opposite directions when they move simultaneously, so as to make the two precast shear walls 1 move away from each other or move closer to each other.

[0030] In other embodiments: the fastener 21 can be an elastic buckle structure. The end of the connecting rod 41 near the first connecting plate 2 is connected to the end of the elastic buckle by a pin. The first connecting plate 2 is provided with a groove that matches the elastic buckle. The elastic buckle can be locked into the groove. After being locked, the elastic buckle can be slightly deformed under a certain external force to adapt to the small movement of the connecting rod 41 and ensure the stability of the connection.

[0031] Specifically, both the first connecting plate 2 and the second connecting plate 3 are provided with bolt sleeves 5 for connecting to the precast shear wall 1. The bolt sleeves 5 are installed on the end faces of the first connecting plate 2 and the second connecting plate 3 facing the precast shear wall 1, and there are 4 to 6 of them arranged in a matrix. Their inner diameter matches the diameter of the connecting bolts pre-embedded on the precast shear wall 1. The precast shear wall 1 achieves a fixed connection between the first connecting plate 2, the second connecting plate 3, and the corresponding precast shear wall 1 through the engagement of the bolts and threaded sleeves 5.

[0032] To adjust the gap between the two precast shear walls 1, the connecting rod 41 can be rotated clockwise. After rotation, the connecting rod 41 will move towards the second connecting plate 3 through the threaded connection with the threaded sleeve 311. When the connecting rod 41 moves, it will drive the first connecting plate 2 to move through the abutment plate 211. This will allow the precast shear wall 1 connected to the first connecting plate 2 to move towards the other precast shear wall 1, thereby reducing the gap between the two precast shear walls 1. At the same time, if the connecting rod 41 is reversed, the first connecting plate 2 can move the precast shear wall 1 connected to it away from the other precast shear wall 1.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
