Technical Field

[0001] This utility model relates to the field of curved structure wall installation technology, and in particular to a fastener for reinforcing curved structure walls. Background Technology

[0002] Structural walls, also known as shear walls, wind-resistant walls, or earthquake-resistant walls, are walls in buildings or structures that primarily bear horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing structural shear failure. In building design, curved walls, due to their unique shape, are an effective way to enhance architectural aesthetics. However, because of their curved characteristics, the selection of reinforcement points is more cautious and complex compared to flat walls. Furthermore, commonly used reinforcement components are often applied to relatively simple flat walls and are difficult to adapt to the complex shapes and dimensional changes of curved structural walls, resulting in suboptimal reinforcement effects.

[0023] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0025] Reference Figures 1-6 This embodiment provides a fastener for reinforcing curved structural walls. It includes a support column 1 axially parallel to the leeward side of the curved structural wall, and a retaining component 2 arranged axially along the support column 1. In use, the support column 1 is fixed with anchor bolts 22c to ensure structural stability and prevent tilting. The end of the retaining component 2 furthest from the support column 1 contacts the leeward side of the curved structural wall and applies pressure to it, thereby reinforcing the wall and enhancing its wind resistance. Furthermore, in this embodiment, the retaining component 2 is arranged axially along the support column 1, increasing the number of reinforcement points and preventing excessive pressure concentration on the leeward side of the curved structural wall, which could cause damage to the cable outlet.

[0026] Specifically, the reinforcement component 2 includes an installation ring 21 sleeved on the outside of the support column 1, and a reinforcement rod 22 movably connected to the installation ring 21. The outer circumferential surface of the installation ring 21 is provided with an annular groove 21a. One end of the reinforcement rod 22 is provided with an elastic pressure plate 23 that abuts against the concave surface of the curved structural wall. The other end of the reinforcement rod 22 is provided with a slider 24 that can slide along the annular groove 21a. The slider 24 and the annular groove 21a can slide together, so that during use, the position of the elastic pressure plate 23 in contact with the leeward side of the curved structural wall can be changed by rotating and adjusting the reinforcement rod 22. This allows for reasonable adjustment of the reinforcement points according to the size and shape of the curved structural wall without moving the support column 1.

[0027] Specifically, the side wall of the annular groove 21a is coaxially provided with an arc-shaped groove 21c, and the side wall of the slider 24 is provided with an anti-detachment block 29 embedded in the arc-shaped groove 21c.

[0028] like Figure 2 As shown, two symmetrically structured retaining rods 22 are movably connected to a single mounting ring 21. In use, by unfolding the two retaining rods 22 outward, the elastic pressure plates 23 at the ends of the two retaining rods 22 can contact two different positions on the leeward side of the curved structural wall. Since the two retaining rods 22 can rotate independently, even if the support column 1 is installed on the symmetrical line offset from the curved structural wall, by adjusting the rotation of the retaining rods 22, the two elastic pressure plates 23 can contact two symmetrical positions on the leeward side of the curved structural wall. This allows the retaining rods 22 to provide symmetrical support to the curved structural wall, ensuring uniform load-bearing on both sides of the leeward side of the curved structural wall.

[0029] As an optional embodiment, the outer circumferential surface of the mounting ring 21 is provided with slots 21b arranged circumferentially, and the end of the retaining rod 22 near the mounting ring 21 is movably provided with a rotating shaft 25. The outside of the rotating shaft 25 is movably sleeved with an insert rod 26. One end of the insert rod 26 can be inserted into the slot 21b, and the insert rod 26 can rotate in the first direction to disengage from the slot 21b.

[0030] Furthermore, the insertion rod 26 has a through-slot 26a, and the end of the retaining rod 22 near the mounting ring 21 is also provided with a spring buffer 27. The output rod end of the spring buffer 27 passes through the through-slot 26a and is provided with a pull-back block 28. The pull-back block 28 can make the insertion rod 26 rotate in the second direction and embed into the slot 21b.

[0031] Specifically, such as Figure 2 and 5 As shown, both retaining rods 22 on the mounting ring 21 can be rotated to the sides. To prevent them from rotating back after being rotated, the retaining rods 22 are locked by the cooperation of the insert rod 26 and the slot 21b. That is, when the insert rod 26 is inserted into the slot 21b, the rotation of the retaining rods 22 can be locked.

[0032] Specifically, the first direction is the direction in which the side wall of the slot 21b (or the outer circumference of the mounting ring 21) applies a pushing force to the insertion rod 26 when the retaining rod 22 rotates. Under this pushing force, the insertion rod 26 rotates and disengages from the slot 21b. When the insert rod 26 rotates out of the slot 21b, it simultaneously pushes the pull-back block 28, causing the output rod of the elastic damper 27 to extend. The elastic damper 27 is existing technology and can be either a hydraulic elastic damper or a spring damper. The second direction is opposite to the first direction. After the insert rod 26 is out of the slot 21b, it continues to rotate the retaining rod 22, so that the end of the insert rod 26 used to lock the retaining rod 22 is placed outside the other slot 21b. At this time, the insert rod 26 does not contact any side of the mounting ring 21 and is not subject to the thrust in the first direction. At this time, under the elastic recovery of the elastic damper 27, the pull-back block 28 pulls the insert rod 26 back to rotate in the second direction, so that the end of the insert rod 26 can automatically embed into the other slot 21b and relock the retaining rod 22.

[0033] Specifically, the pull-back block 28 is spherical, the output rod of the elastic buffer 27 extends and retracts linearly, while the movement of the insertion rod 26 is a rotational motion. When the insertion rod 26 and the output rod of the elastic buffer 27 move, the relative positions of the pull-back block 28 and the long groove 26a will change. The pull-back block 28 is spherical, which can effectively reduce the jamming when the output rod of the elastic buffer 27 extends and retracts.

[0034] Specifically, the diameter of the pull-back block 28 is larger than the width of the long slot 26a, ensuring that when the insertion rod 26 moves in the first direction, the output rod of the elastic buffer 27 can be extended by pulling the pull-back block 28, and also ensuring that when the output rod of the elastic buffer 27 retracts, the insertion rod 26 can be moved in the second direction by pulling the pull-back block 28 to be re-inserted into the slot 21b.

[0035] As an optional embodiment, the retaining rod 22 includes an adjusting cylinder 22a that is axially vertically arranged on the mounting ring 21. The adjusting cylinder 22a has a slot 22a-1 arranged axially and one end is open. An adjusting post 22b is slidably inserted into the slot 22a-1.

[0036] Furthermore, the outer wall of the adjusting cylinder 22a is provided with a threaded hole 22a-2 that communicates with the slot 22a-1 at one end near the opening. A bolt 22c is connected to the threaded hole 22a-2 by an internal thread. One end of the bolt 22c that extends into the slot 22a-1 can abut against the side wall opposite to the adjusting column 22b.

[0037] Specifically, the slider 24 is located at the end of the adjusting cylinder 22a away from the opening, and the elastic pressure plate 23 is located at the end of the adjusting column 22b that extends out of the slot 22a-1.

[0038] Specifically, the anti-reinforcing rod 22 is designed to be telescopically adjustable. Its purpose is that when the support column 1 is installed on the symmetry line of the offset curved structural wall, rotating and adjusting the two anti-reinforcing rods 22 will inevitably result in one needing to contract and the other needing to extend, so as to ensure that the elastic pressure plate 23 can press against the leeward side of the curved structural wall. The anti-reinforcing rod 22 after length adjustment is locked by setting bolts 22c.

[0039] As an optional embodiment, the end of the adjusting column 22b connected to the elastic pressure plate 23 is provided with two symmetrically arranged mounting rods 22b-1. The two mounting rods 22b-1 extend outward in a figure-eight shape and have a notched perforation 22b-1a at the movable end. The elastic pressure plate 23 is in the shape of an arc-shaped plate. The outer convex surface of the elastic pressure plate 23 is adjacent to the curved structural wall and is bonded with a rubber pad 23a. The inner concave surface of the elastic pressure plate 23 is provided with a connecting frame 23b, and the connecting frame 23b can be inserted into the perforation 22b-1a from the notch.

[0040] Furthermore, the size of the perforation 22b-1a is larger than the cross-sectional size of the connecting frame 23b, so that the connecting frame 23b has a certain amount of room to move within the perforation 22b-1a. This ensures that when the elastic pressure plate 23 deforms in response to the curved structural wall with different curvatures, the connecting frame 23b can deform synchronously with the elastic pressure plate 23 and recover synchronously after the elastic pressure plate 23 recovers.

[0041] Specifically, by setting rubber pad 23a, the contact between the elastic pressure plate 23 and the curved structural wall is soft, which plays a buffering role and reduces stress concentration when the elastic pressure plate 23 contacts the curved structural wall, thus reducing the damage to the curved structural wall.

[0042] Specifically, the elastic pressure plate 23 is an arc-shaped plate, which means that when using this device, there is no need to consider whether the elastic pressure plate 23 is compatible with the curvature of the curved structural wall. Through compression, the elastic pressure plate 23 can automatically fit into curved structural walls with different curvatures.

[0043] As an optional embodiment, the reinforcing fastener also includes a spacer 3, which is sleeved on the outside of the support column 1 and disposed between two adjacent mounting rings 21 to space between two adjacent abutment components 2 and prevent the abutment components 2 from sliding down the support rod.

[0044] Specifically, during use, the spacing between two adjacent anti-fixing components 2 should be reasonably arranged according to the height of the curved structure wall, and a partition cylinder 3 of corresponding length should be installed according to the interval.

[0045] As an optional embodiment, to ensure that the mounting ring 21 does not deflect when supporting the curved structural wall, the support column 1 is a prism, and both the mounting ring 21 and the partition cylinder 3 are provided with mounting holes H that are the same as the radial cross-sectional contour of the support column 1.

[0046] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
