Description

Technical Field

[0001] This invention relates to the field of support device technology, and in particular to an anti-deformation support device for a thin-walled double-limb steel plate composite shear wall. Background Technology

[0002] In the process of segmented fabrication, transportation, and temporary on-site storage of thin-walled double-limb steel plate composite shear walls, in order to effectively control the plastic deformation of the free edges of the double-limb steel plate joints (designed without joint end diaphragms), reduce misalignment of the steel plate wall joints, and improve on-site assembly accuracy and welding quality, the common practice is to weld independent steel strips at intervals inside the free edges of the double-limb steel plate joints for internal bracing. However, in traditional internal bracing structures, welding the steel strips to the thin-walled steel plate wall will cause residual welding stress and strain. At the same time, when the vertical deviation between the independent steel strips and the upper and lower double-layer steel plate walls is too large, translational misalignment deformation of the upper and lower layers is prone to occur during compression. This not only places high demands on the assembly accuracy and welding deformation control of the steel strips in the factory, but also makes them unusable, resulting in wasted labor and materials. Therefore, how to design a deformation-resistant support device that can effectively support the free edges of thin-walled double-limb steel plate walls and can be reused has become a problem that needs to be solved by those in this field. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned shortcomings by providing an anti-deformation support device for a thin-walled double-limb steel plate composite shear wall, which can effectively support the free edges of the thin-walled double-limb steel plate wall and can be reused repeatedly.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a deformation-resistant support device for a thin-walled double-limb steel plate composite shear wall, comprising: Two U-shaped clamps, one above the other, can respectively clamp onto the upper and lower free edges of the joint of the thin-walled double-limb steel plate wall; A support adjustment component is disposed between the two U-shaped clamps. The support adjustment component can adjust the distance between the two U-shaped clamps and can also limit and fix them after the distance is adjusted. The support adjustment component includes: The telescopic component has its telescopic end and fixed end connected to two U-shaped clamps, respectively. A height adjustment component is provided on the telescopic component. It can drive the telescopic end of the telescopic component to move up and down, and can also limit its movement after the telescopic end has moved to the corresponding height.

[0005] Furthermore, the telescopic component includes an internally hollow adjustment seat, an adjustment plate slidably disposed inside the adjustment seat, and a strip-shaped, vertically arranged guide groove on the side wall of the adjustment seat. One side of the height adjustment component passes through the guide groove and is connected to the adjustment plate.

[0006] Furthermore, the height adjustment component includes a first mounting platform disposed on the adjustment plate. The bottom of the first mounting platform is detachably provided with an abutment platform having a sloping bottom. A second mounting platform is slidably disposed on the outer wall of the adjustment seat. The top of the second mounting platform is detachably provided with an abutment block having rounded corners. When the abutment block moves laterally, it can abut against the sloping bottom of the abutment platform and drive the adjustment plate to move up and down. The adjusting seat is provided with a mounting bracket, which has a through hole. An adjusting shaft is rotatably inserted into the mounting bracket laterally. A threaded section with a diameter larger than the adjusting shaft and a threaded surface is provided at the corresponding position of the adjusting shaft. The threaded section is screwed into the second mounting platform. Two blocking nuts are also screwed onto the threaded section, which are located on both sides of the second mounting platform. The inner diameter of the through hole is larger than the diameter of the threaded section.

[0007] Furthermore, an installation ring is provided on the inner side of the mounting bracket, and the installation ring is sleeved on the corresponding position of the adjusting shaft. Anti-loosening nuts are provided on both sides of the adjusting shaft.

[0008] Furthermore, it also includes a diagonal brace assembly, which includes a support rod hinged to the bottom of the top U-shaped clamp. The end of the support rod away from the U-shaped clamp is hinged to a threaded platform. The threaded platform is slidably mounted on an adjustment seat. An adjustment screw is rotatably and vertically mounted on the adjustment seat, and the adjustment screw is screwed into the threaded platform.

[0009] Furthermore, there are multiple support adjustment components, and each of the threaded platforms is connected by a connecting shaft.

[0010] Furthermore, it also includes a lower support assembly, which is movably disposed at the bottom of the telescopic component.

[0011] Furthermore, a gasket is provided on the inner wall of the U-shaped clamp.

[0012] Furthermore, the U-shaped clamp includes a U-shaped clamping platform, a positioning nut is welded to the top of the clamping platform, and a stud is screwed onto the positioning nut, penetrating the top wall of the clamping platform and extending therein. There are two studs and two positioning nuts, and a limit plate is rotatably provided at the bottom of the stud.

[0013] The beneficial effects of this invention are reflected in: In this invention, the distance between the telescopic end and the fixed end of the telescopic component is adjusted by a height adjustment component, so that the distance between the two U-shaped clamps can be adaptively adjusted according to the distance between the upper and lower free edges of the thin-walled double-limb steel plate wall. In addition, the height adjustment component can also limit the telescopic end of the telescopic component after it moves to the corresponding height, thereby supporting the upper and lower free edges of the thin-walled double-limb steel plate wall. Therefore, this device can effectively control the deformation of the steel plate wall joint during the manufacturing, transportation and stacking stages, and the device can also be disassembled and reused later.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-7 This invention discloses an anti-deformation support device for a thin-walled double-limb steel plate composite shear wall, comprising two U-shaped clamps 1 distributed vertically, which can be clamped at the upper and lower free edges of the thin-walled double-limb steel plate wall 7 respectively. A support adjustment component is provided between the two U-shaped clamps 1, which can adjust the distance between the two U-shaped clamps 1 and limit and fix them after the distance is adjusted.

[0018] In one embodiment, the support adjustment assembly includes a support adjustment component 2, which is composed of a support screw 201, a first mounting nut 202, and a second mounting nut 203. There are two of each of the first mounting nuts 202 and the second mounting nuts 203, which are respectively disposed at the top and bottom of the corresponding U-shaped clamp 1. The first mounting nut 202 is welded to the corresponding U-shaped clamp 1. The support screw 201 is also interposed between the two U-shaped clamps 1, and the support screw 201 is screwed into the first mounting nut 202 and the second mounting nut 203.

[0019] In practice, workers first need to drill holes at the corresponding positions of the thin-walled double-limb steel plate wall 7, then install two U-shaped clamps 1 at the corresponding free edges of the joint, then insert the support screw 201 through the hole, and install it between the two U-shaped clamps 1 by rotating the support screw 201 and the second mounting nut 203. This can effectively control the deformation of the joint of the steel plate wall during the manufacturing, transportation and stacking stages. At the same time, the device can be disassembled and reused later.

[0020] In another embodiment of this application, the support adjustment assembly includes a telescopic component 3 and a height adjustment component 4. The telescopic end and the fixed end of the telescopic component 3 are respectively connected to two U-shaped clamps 1. The height adjustment component 4 is disposed on the telescopic component 3 and can drive the telescopic end of the telescopic component 3 to move up and down. It can also limit the telescopic end of the telescopic component 3 after it moves to the corresponding height.

[0021] In specific implementation, the height adjustment component 4 is used to adjust the distance between the telescopic end and the fixed end of the telescopic component 3, so that the distance between the two U-shaped clamps 1 can be adaptively adjusted according to the distance between the upper and lower free edges of the thin-walled double-limb steel plate wall 7. In addition, the height adjustment component 4 can also limit the telescopic end of the telescopic component 3 after it moves to the corresponding height, thereby supporting the upper and lower free edges of the thin-walled double-limb steel plate wall 7.

[0022] In one embodiment, the telescopic component 3 includes an internally hollow adjusting seat 301, an adjusting plate 302 is slidably inserted inside the adjusting seat 301, and a strip-shaped and vertically arranged guide groove is provided on the side wall of the adjusting seat 301. One side of the height adjusting component 4 passes through the guide groove and is connected to the adjusting plate 302.

[0023] In one embodiment, the height adjustment component 4 includes a first mounting platform 401 mounted on the adjustment plate 302. A contact platform 402 with a sloping bottom is detachably mounted on the bottom of the first mounting platform 401. A second mounting platform 403 is laterally slidable on the outer wall of the adjustment plate 301. A rounded-corner contact block 404 is detachably mounted on the top of the second mounting platform 403. When the contact block 404 moves laterally, it engages with the sloping bottom of the contact platform 402, thereby causing the adjustment plate 302 to move up and down. An adjustment base 301 is equipped with a mounting bracket 405. The mounting bracket 405 has a through hole. An adjustment shaft 406 is rotatably inserted into the mounting bracket 405. The corresponding part of the adjustment shaft 406 has a threaded section 407 with a diameter larger than the adjustment shaft 406 and a thread on its surface. The threaded section 407 is screwed into the second mounting platform 403. Two blocking nuts 408 are also screwed onto the threaded section 407 and are located on both sides of the second mounting platform 403. The inner diameter of the through hole is larger than the diameter of the threaded section 407.

[0024] In practice, rotating the adjusting shaft 406 and the threaded section 407 can drive the second mounting platform 403 to move laterally on the first mounting platform 401. During this process, the abutment block 404 moves along with it, and its rounded corner contacts the inclined surface of the abutment platform 402, thereby driving the abutment block 404 to move up or down. The adjusting plate 302 will also move along with it, thus changing the distance between the two U-shaped clamps 1. After the position of the second mounting platform 403 is adjusted, the blocking nuts 408 on both sides are rotated to make it fit against the second mounting platform 403 and limit its position. Multiple of these devices are usually installed on one side of the thin-walled double-limb steel plate wall 7. Two or three of these devices on the same side can be adjusted synchronously through an adjusting shaft 406, thereby omitting most of the repetitive and tedious operation steps.

[0025] In addition, the height adjustment component 4, through the engagement of the abutment block 404 with the inclined surface of the abutment platform 402, transforms the vertical load-bearing into lateral force, thus dispersing stress concentration and improving its load-bearing stability and service life. The double blocking nut 408 achieves bidirectional locking of the second mounting platform 403, resisting vibration displacement and improving positioning accuracy. In actual situations, the abutment block 404 of different heights can be replaced to adapt to the free edge spacing of the two interfaces of the thin-walled double-limb steel plate wall 7, thus reducing maintenance costs and improving the flexibility of use.

[0026] In one embodiment, a mounting ring 409 is inserted into the inner side of the mounting bracket 405. The mounting ring 409 is sleeved on the corresponding position of the adjusting shaft 406. Anti-loosening nuts 410 are provided on both sides of the adjusting shaft 406. Specifically, the corresponding position of the adjusting shaft 406 is threaded, and the anti-loosening nut 410 can be screwed onto the thread.

[0027] In practice, since the inner diameter of the through hole on the mounting bracket 405 is larger than the diameter of the threaded section 407, there is a gap between the adjusting shaft 406 and the through hole for the mounting ring 409 to be inserted. When the adjusting shaft 406 is rotated, the anti-loosening nut 410 does not contact the mounting bracket 405. After the mounting bracket 405 is adjusted, the anti-loosening nut 410 is rotated to make it fit tightly against the mounting bracket 405. The anti-loosening nuts 410 on both sides of the adjusting shaft 406 fit tightly against the mounting bracket 405 on the corresponding telescopic component 3, thereby preventing the adjusting shaft 406 from being dislodged and positioning it.

[0028] In one embodiment, the device further includes a diagonal brace assembly 5, which includes a support rod 501 hinged to the bottom of the top U-shaped clamp 1. A threaded platform 502 is hinged to one end of the support rod 501 away from the U-shaped clamp 1. The threaded platform 502 is slidably mounted on an adjusting seat 301. An adjusting screw 503 is rotatably and vertically mounted on the adjusting seat 301. The adjusting screw 503 is screwed into the threaded platform 502.

[0029] In practice, rotating the adjusting screw 503 can drive the threaded table 502 to move up or down. Its cooperation with the support rod 501 can provide secondary support for the U-shaped clamp 1 on the adjusting plate 302 after the movement is completed, thus improving the safety of the device.

[0030] In one embodiment, there are multiple support adjustment components, and each threaded platform 502 is connected by a connecting shaft 504.

[0031] In practice, each threaded platform 502 and support rod 501 is provided with insertion holes, and the connecting shaft 504 can be inserted into each insertion hole. Therefore, the operator can adjust the threaded platform 502 to the corresponding height in advance according to the corresponding size of the thin-walled double-limb steel plate wall 7, and finally rotate the support rod 501 until its insertion hole is aligned with the insertion hole on the threaded platform 502. Finally, the connecting shaft 504 is inserted into each insertion hole. This method does not require the operator to put their hand into the thin-walled double-limb steel plate wall 7 to rotate the adjusting screw 503, thus improving the convenience of operation.

[0032] In one embodiment, the device further includes a lower support component 6, which is movably disposed at the bottom of the telescopic component 3.

[0033] In practice, the lower support assembly 6 can be lowered to contact the ground, thereby further distributing the pressure on the device and its connection with the thin-walled double-limb steel plate wall 7. The lower support assembly 6 can be positioned by using threads and nuts.

[0034] In one embodiment, a soft pad (not shown) is installed on the inner wall of the U-shaped clamp 1.

[0035] Please see Figure 8 In one embodiment, the U-shaped clamp 1 includes a U-shaped clamping platform 101. A positioning nut 104 is welded to the top of the clamping platform 101. A stud 102 is screwed onto the positioning nut 104, penetrating the top wall of the clamping platform 101 and extending therein. There are two studs 102 and two positioning nuts 104. A limit plate 103 is rotatably mounted on the bottom of the stud 102.

[0036] In practice, workers can rotate the two studs 102 to change their relative position with the positioning nut 104, thereby causing the limiting plate 103 to move up or down and to clamp the upper and lower free edges of the thin-walled double-limb steel plate wall 7 of different thicknesses.

[0037] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
