Technical Field
[0001] This utility model relates to the field of hole-expanding anchor bolt technology, and in particular to a hole-expanding anchor bolt for building curtain walls. Background Technology
[0002] Building curtain walls are building envelopes or decorative structures composed of a supporting structural system and panels. They have a certain displacement capacity relative to the main structure and do not share the load and action of the main structure. They have advantages such as superior physical properties, light weight, flexible design, and strong seismic resistance. The use of expanded hole anchors for building curtain walls can improve the reliability of anchoring, adapt to different substrates and load conditions, enhance seismic performance, and facilitate construction and installation. Traditional expanded hole anchors for building curtain walls are complicated to use, have low construction efficiency, high requirements for substrates, limited anchoring stability, and high cost. In order to achieve the anchoring requirements of modern anchors, new types of expanded hole anchors for building curtain walls are used.
[0003] In existing technologies, once the expanded bolts are fixed, they are generally difficult to remove due to the expansion of the expansion plates. If the bolts are forcibly removed, it may damage the wall, leading to bolt damage and increased construction costs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an enlarged-hole anchor for building curtain walls, which aims to solve the problem that enlarged-hole anchors are generally difficult to disassemble after being fixed due to the expansion of the expansion plate. If the anchor is forcibly disassembled, it may damage the wall, resulting in anchor damage and increased construction costs.
[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0025] Specifically, rotating bolt 21 drives moving ring 16 to move bracket 2 15, which in turn drives connecting rod 2 13 to move, causing expanding plate 14 to move simultaneously. Under the action of fixing block 1 and bracket 1 11, connecting rod 1 12 will rotate when connecting rod 2 13 moves, thus preventing damage to anchor bolts and walls after disassembly and achieving cost reduction.
[0026] Reference Figure 1 and Figure 3The load-bearing component includes a load-bearing block 2, the lower surface of the load-bearing block 2 is fixedly connected to the upper surface of the fixed block 1, the inner wall of the load-bearing block 2 is rotatably connected to a bolt 21, the outer wall of the bolt 21 is rotatably connected to the inner wall of the fixed block 1, the inner wall of the bolt 21 is provided with a positioning groove 22, and the outer wall of the load-bearing block 2 is provided with a fixing ring 3.
[0027] Specifically, by rotating bolt 21 on the inner wall of bearing block 2, connecting rod 12 and connecting rod 23 are retracted or extended, thereby achieving the effect of enlarging the hole in the wall.
[0028] Reference Figure 1 and Figure 4 A connecting block 31 is slidably connected to the outer wall of the fixed ring 3. A push rod 32 is slidably connected to the inner wall of the connecting block 31. A spring 33 is provided on the outer wall of the push rod 32, and the outer wall of the spring 33 is fixedly connected to the outer wall of the connecting block 31. A locking block 34 is fixedly connected to the outer wall of the push rod 32, and the outer wall of the locking block 34 is slidably connected to the inner wall of the positioning groove 22. A second push rod 35 is fixedly connected to the inner wall of the connecting block 31, and the outer wall of the second push rod 35 is slidably connected to the inner wall of the fixed ring 3. A second spring 36 is provided on the outer wall of the second push rod 35. The outer wall of spring 2 36 is fixedly connected to the outer wall of fixed ring 3; the outer wall of push rod 2 35 is slidably connected to rotating ring 37, and the outer wall of rotating ring 37 is slidably connected to the inner wall of fixed ring 3; the outer wall of rotating ring 37 is fixedly connected to limiting block 38, and the outer wall of limiting block 38 is slidably connected to the inner wall of push rod 2 35; the inner wall of push rod 2 35 is provided with limiting groove; the outer wall of limiting block 38 is slidably connected to the inner wall of limiting groove; the upper surface of rotating ring 37 is fixedly connected to lever 39, and the outer wall of lever 39 is slidably connected to the inner wall of fixed ring 3.
[0029] Specifically, during installation, the bolt 21 is rotated on the inner wall of the bearing block 2. At the same time, the bolt 21 pushes the locking block 34, causing the push rod 32 to move. This causes the spring 33 on the push rod 32 to deform. The rebound of the spring 33 allows the locking block 34 to be stably pushed back to lock the bolt 21. When disassembly is required, the lever 39 is first moved to rotate the rotating ring 37. The rotating ring 37 pushes the push rod 35, causing the spring 36 to deform. The spring 36 then drives the connecting block 31 to move, causing the push rod 32 to move the locking block 34 away from the inner wall of the bolt 21. This achieves the effect of automatically locking and unlocking the bolt 21.
[0030] Working principle: When this device is needed, the bearing block 2 and bolt 21 are first inserted into the hole opened in the wall. Rotating bolt 21 moves the moving ring 16, causing the bracket 15 to move simultaneously. The movement of bracket 15 causes the connecting rod 13 to rotate simultaneously, further moving the expanding plate 14. Under the action of the fixing block 1 and bracket 11, the connecting rod 12 rotates synchronously when the connecting rod 13 rotates. The movement of the expanding plate 14 increases the contact area between the anchor bolt and the inside of the wall, thereby achieving the effect of expanding the hole. At the same time as the bolt 21 rotates, the bolt 21 pushes the locking block 34 to move, causing the push rod 32 to move. The spring 33 on the push rod 32 will deform, and the locking block 34 can prevent the anchoring force of the bolt 21 from decreasing due to vibration. When disassembly is required, the lever 39 is moved to drive the rotating ring 37 to move the push rod 35. At the same time as the push rod 35 moves, the limiting block 38 will be locked into the limiting groove, and the spring 36 will undergo elastic deformation. The movement of the spring 36 will drive the connecting block 31 to make the push rod 32 drive the locking block 34 to leave the positioning groove 22 opened on the bolt 21. This anchor can be disassembled without damaging the anchor and the wall, thus reducing costs. On the other hand, it can automatically lock and unlock the bolt 21.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
