Description

Technical Field

[0001] This utility model relates to the field of building measurement technology, and in particular to a right-angle positioning device suitable for prefabricated wall panels. Background Technology

[0002] With the booming development of prefabricated buildings, right-angle positioning devices for prefabricated wall panels have emerged as a key tool to ensure construction quality and efficiency.

[0003] The right-angle locator for prefabricated wall panels is a precision device specifically designed for right-angle positioning during the installation of prefabricated wall panels. It is typically made of high-strength, wear-resistant materials, with a robust structure and ingenious design. Its core components include a precise right-angle positioning module, an adjustable fixing device, and an operating handle. When installing wall panels, the construction worker only needs to place the locator in the predetermined position and adjust the fixing device to ensure a tight fit with the wall panel. The right-angle positioning module ensures that the angle of the wall panel installation is accurate, and the error can be controlled within a very small range.

[0004] This small locator holds immense significance. From a quality perspective, it effectively solves the problem of wall panel installation angle deviation caused by manual operation in traditional construction, ensuring the verticality and squareness of the building structure, greatly improving the overall quality of prefabricated buildings, and reducing rework and maintenance costs caused by angle deviation later. From an efficiency perspective, using a right-angle locator can significantly shorten the wall panel installation time.

[0005] Existing right-angle positioners cannot adjust the clamping width when positioning wall panels of different sizes, making them prone to stress and requiring excessive force. Furthermore, they cannot be adjusted for rotation, remaining at a right angle, which makes them susceptible to deformation due to pressure from the wall panel during adjustment. The existing positioning and fixing mechanism can only fix the two sides, leaving the middle position unfixed, which can lead to errors. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model discloses a right-angle locator device suitable for prefabricated wall panels, effectively solving the problems in the background art. In use, the clamping plates on the right-angle arms can be freely adjusted to accommodate different wall panel thicknesses. The position of the clamping plates holding the wall panel can be adjusted by sliding slider B. When the wall panel is large, slider B can be slid outwards as much as possible, making the clamping position further outwards, thus increasing the clamping force arm and reducing effort. This utility model can fix the wall panel at either the inner or outer angle. Furthermore, the connection between the two right-angle arms is rotatable. For fixing large components like wall panels, the right-angle arms are first fixed to the two wall panels, then adjusted to a right angle to guide the wall panels to be perpendicular. The device is then reinforced with limiting clips, ensuring it remains stable and perpendicular to the wall panel. This not only makes fixing effortless but also protects the device from deformation caused by the wall panel.

[0007] A right-angle locator device suitable for prefabricated wall panels has two right-angle arms connected by a rotating shaft. The upper part of the rotating shaft extends three times the thickness of the right-angle arm. One end of a connecting rod is rotatably connected to a short shaft on one of the right-angle arms, and the other end of the connecting rod is rotatably connected to a short shaft on slider A. Slider A is slidably installed in a groove on the other right-angle arm. The right-angle arm is also provided with two slots, in which buckles are slidably installed to lock the two sides of slider A.

[0008] Preferably, slider A is provided with a pointer, and the right-angled arm pointed to by the pointer is provided with a scale, and the protruding scale line in the middle of the scale represents that the two right-angled arms are perpendicular to each other.

[0009] Preferably, both right-angle arms are provided with open slide grooves, and sliders B are slidably installed in the slide grooves. The upper end of slider B is provided with a short shaft, which is rotatably connected to the round hole below connector A. Connector A is provided with two horizontal round holes, and long rods A are slidably installed in the round holes. One end of long rod A is fixedly installed with a clamping plate, and the other end of long rod A is fixedly installed with a short plate A.

[0010] Preferably, the clamping plate has a slot on its underside, the size of which is the same as the protrusion at one end of the right-angle arm, so that they are locked together when not in use.

[0011] Preferably, the short plate A is threadedly connected to the threaded rod A, and one end of the threaded rod A is rotatably connected to the round hole in the middle of the connector A.

[0012] Preferably, a connector B is movably mounted on the rotating shaft. The connector B has two horizontal circular holes. A long rod B is slidably mounted in the circular holes. A transition plate is fixedly mounted on one end of the long rod B. The other end of the long rod B is fixedly connected to a short plate B. The short plate B is threadedly connected to a threaded rod B. One end of the threaded rod B is rotatably connected to the circular holes on the connector B.

[0013] Preferably, a vertical rod is fixedly installed on the lower side of the transition plate, and a limit clip is fixedly installed at the lower end of the vertical rod. The limit clip is heart-shaped.

[0014] The advantages of this utility model compared with the prior art are: 1. When using this utility model, the clamping plate on the right-angle arm can be freely adjusted in distance to adapt to different wall panel thicknesses, and the position of the clamping plate holding the wall panel can be adjusted by sliding slider B. When the wall panel is large, slider B can be slid outward as much as possible to make the clamping position further outward, thereby making the clamping lever arm larger and the clamping more labor-saving.

[0015] When using this invention, it can be fixed at either the inner or outer corner of the positioning wall panel. Furthermore, the connection between the two right-angle arms is rotatable. For fixing large components like wall panels, the right-angle arms are first fixed to the two wall panels, then adjusted to right angles to guide the wall panels to be perpendicular to each other. Finally, the device is reinforced and fixed by the limiting clips, ensuring that the device remains stable and perpendicular to the wall panels. This not only makes fixing effortless but also protects the device from being squeezed and deformed by the wall panels. Attached Figure Description

[0027] Implementation, for example Figures 1-8 As shown, a right-angle locator device suitable for prefabricated wall panels;

[0028] In one optional embodiment of this utility model, such as Figure 4As shown, there are two right-angle arms 1, which are rotatably connected by a pivot 2. The upper part of the pivot 2 extends three times the thickness of the right-angle arm 1. One end of the connecting rod 3 is rotatably connected to a short shaft on one of the right-angle arms 1, and the other end of the connecting rod 3 is rotatably connected to a short shaft on the slider A5. The slider A5 is slidably installed in a groove on the other right-angle arm 1. The right-angle arm 1 is also provided with two slots, in which buckles 4 are slidably installed. The buckles 4 can lock the two sides of the slider A5.

[0029] In one optional embodiment of this utility model, such as Figure 4 As shown, slider A5 has a pointer, and the pointer points to a scale on the right-angled arm 1. The protruding scale line in the middle of the scale represents that the two right-angled arms 1 are perpendicular to each other.

[0030] In one optional embodiment of this utility model, such as Figure 5 , Figure 6 As shown, both right-angle arms 1 are provided with open slide grooves, and sliders B6 are slidably installed in the slide grooves. The upper end of slider B6 is provided with a short shaft, which is rotatably connected to the round hole below connector A7. Connector A7 is provided with two horizontal round holes, and long rods A9 are slidably installed in the round holes. One end of long rod A9 is fixedly installed with a clamping plate 8, and the other end of long rod A9 is fixedly installed with a short plate A10.

[0031] In one optional embodiment of this utility model, such as Figure 5 As shown, a slot is provided on the bottom of the clamping plate 8. The size of the slot is the same as the protrusion at one end of the right-angle arm 1, and they are locked together when not in use.

[0032] In one optional embodiment of this utility model, such as Figure 6 As shown, the short plate A10 is threadedly connected to the threaded rod A11, and one end of the threaded rod A11 is rotatably connected to the round hole in the middle of the connector A7.

[0033] In one optional embodiment of this utility model, such as Figure 7 , Figure 8 As shown, a connector B12 is movably mounted on the rotating shaft 2. The connector B12 has two horizontal circular holes. A long rod B13 is slidably mounted in the circular holes. A transition plate 14 is fixedly mounted on one end of the long rod B13. The other end of the long rod B13 is fixedly connected to a short plate B15. The short plate B15 is threadedly connected to a threaded rod B18. One end of the threaded rod B18 is rotatably connected to the circular hole on the connector B12.

[0034] In one optional embodiment of this utility model, such as Figure 8 As shown, a vertical rod 16 is fixedly installed on the lower side of the transition plate 14, and a limiter 17 is fixedly installed at the lower end of the vertical rod 16. The limiter 17 is heart-shaped.

[0035] Working principle: When using this utility model, it can fix the right angle of the wall panel from the inside or the outside. First, when the device is installed on the inside of the wall panel, the two right angle arms 1 are roughly placed on the upper end of the inside of the wall panel. At the same time, the connector A7 is rotated to rotate the clamping plate 8 to the outer end of the wall panel. Then, the threaded rod A11 is rotated to tighten the clamping plate 8 inward until the wall panel is clamped. The other wall panel is clamped in the same way. After clamping, the angle between the wall panels is adjusted. At this time, the adjustment is fine-tuning. The wall panel will drive the two right angle arms 1 to rotate, thereby driving the connecting rod 3 on the right angle arm 1 to move. The connecting rod 3 drives the slider A5 to slide in the groove on the right angle arm 1 until the pointer of the slider A5 points to the protruding scale line on the scale of the right angle arm 1. At this time, it means that the two right angle arms 1 are perpendicular. At the same time, the buckle 4 is also aligned with the slider A5. The buckle 4 is moved to lock the slider A5, and the fixation is completed.

[0036] Then, manually rotate the threaded rod B18 to drive the limit card 17 on the outside of the wall panel to lock the right angle of the two wall panels. The right angle groove in the middle of the limit card 17 will lock the right angle of the wall panel, thus completing the reinforced fixing and positioning.

[0037] When the device is installed on the outside of the wall panel, the clamping plate 8 needs to be rotated to the inside of the wall panel. Simultaneously, the connector B12 needs to be lifted and rotated, causing the limiting clip 17 to also rotate to the inside of the wall panel for positioning and fixation. The installation method is the same as for the inside installation. Clamp the clamping plate 8 to the wall panel. When clamping, the sliding position of the slider B6 can be selected according to the size of the wall panel. For larger wall panels, the slider B6 can be slid outwards to increase the fixing width. When clamping, the inclined surfaces on both sides of the vertical slot in the middle of the limiting clip 17 are in close contact with the inside of the wall panel, thus completing the reinforced fixing and positioning.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
