Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of steel plate shear wall installation fixed construction tools, specifically a kind of steel plate shear wall installation fixing device. BACKGROUND

[0002] In modern building structure, steel plate shear wall is widely used in high-rise building and large industrial building due to its good seismic performance and bearing capacity. Steel plate shear wall includes arranged steel plate shear wall body, steel column located on both sides of steel plate shear wall body and uniform arrangement of pull hole on steel plate shear wall body. Steel column can be cylinder or steel plate. However, during the installation process of steel plate shear wall, how to achieve quick, accurate and stable fixation is a key problem. Traditional installation and fixation method often has low installation precision, poor fixation and poor applicability, which leads to low construction efficiency and may affect the overall stability of building structure.

[0003] There are two common steel plate shear wall fixation construction methods. The first one is to use temporary positioning code plate to position between steel plate shear wall and steel column. Code plate spacing is set every 1m. Steel plate wall is positioned in place. Code plate and steel plate wall are welded firmly. After steel plate wall and steel column are welded, code plate can be removed. Although the device is simple, it cannot achieve accurate positioning and installation. Code plate is only set on one side of steel plate wall. When operator welds and fixes, steel plate is easy to shift, which leads to inaccurate steel plate wall welding. It can be seen that the device has poor operability.

[0004] The second one is a new type of positioning pull rod that can improve the installation convenience of temporary support. During the installation process of steel plate shear wall, flat head bolt of steel plate shear wall body and pre-buried anchor ring of ground are fixed. The length of telescopic pull rod is adjusted to provide pulling force. For steel plate shear wall with high design height, multiple steel plates are needed to be welded on site to form one side of steel plate shear wall. Different height steel plates need corresponding type of pull rod. The type of pull rod is required. The anchor of pull rod bottom cannot meet the installation requirements when construction is in progress. The operability is poor. UTILITY MODEL CONTENTS

[0033] like Figures 1-4 As shown, this utility model provides a steel plate shear wall installation and fixing device, which mainly includes an adjustment device 1 and a positioning and fixing device 3.

[0034] Multiple adjustment devices 1 are used to fix the steel columns 5 on both sides of the steel plate shear wall 4, and are symmetrically arranged on both sides of the steel plate shear wall 4. In this embodiment, each steel column 5 is provided with two adjustment devices 1, and the two adjustment devices 1 are symmetrically arranged on both sides of the steel plate shear wall 4. The adjustment device 1 includes a first clamping plate 11, a first mounting plate 13, a second clamping plate 14, and a second mounting plate 15. The first clamping plate 11 has a first threaded hole, and a locking bolt 12 is threaded through the first threaded hole. One end of the first mounting plate 13 is perpendicularly connected to the first clamping plate 11, and the second clamping plate 14 is perpendicularly connected to the other end of the first mounting plate 13. An installation groove for the steel column 5 to extend into is provided between the second clamping plate 14 and the first clamping plate 11, which facilitates the installation of the adjustment device 1 on the steel column 5. The length of the first clamping plate 11 is greater than the length of the second clamping plate 14 to further prevent the adjustment device 1 from shaking. 13 is perpendicularly connected to the second clamping plate 14 and located on the side of the second clamping plate 14 away from the first clamping plate 11. The second clamping plate 14 has a second threaded hole. A third mounting plate 16 is perpendicularly connected to the side of the second clamping plate 14 away from the first clamping plate 11. The third mounting plate 16 has a limiting hole, which is coaxial with the second threaded hole. The adjusting screw 2 is screwed through the second threaded hole and passes through the limiting hole. The limiting hole limits the axial movement trajectory of the adjusting screw 2, preventing the adjusting screw 2 from deflecting and ensuring the smoothness and accuracy of the adjustment process. The limiting hole can also be a threaded hole screwed to the adjusting screw 2. One end of the adjusting screw 2 is fixedly provided with a washer 7 for pressing against the steel plate shear wall 4. The washer 7 can increase the contact area and prevent damage to the steel plate shear wall 4.

[0035] Multiple positioning and fixing devices 3 are used to be installed at the joint between two steel plate shear walls 4. In this embodiment, the joint between the two steel plate shear walls 4 includes both horizontal and vertical directions, and two positioning and fixing devices 3 are installed on each joint. Each positioning and fixing device 3 includes two clamping members 31 and four first bolts 32. The two clamping members 31 are symmetrically arranged on both sides of the steel plate shear wall 4 and locked by the first bolts 32. Specifically, the clamping member 31 includes a fourth mounting plate 311 and a third clamping plate 312. The fourth mounting plate 311 is rectangular, and mounting holes are opened at the four corners of the fourth mounting plate 311. The four first bolts 32 correspond to the four mounting holes respectively, and each first bolt 32 passes through the mounting hole of the fourth mounting plate 311, the tie hole 6 of the steel plate shear wall, and the mounting hole of another fourth mounting plate 311 in sequence, and is locked by a nut. One end of the third clamping plate 312 is perpendicularly connected to the middle of the fourth mounting plate 311, and the other end is used to abut against the steel plate shear wall 4. In this embodiment, the end of the third clamping plate 312 that abuts against the steel plate shear wall 4 is fixedly provided with multiple slope plates 8. The slope plates 8 are perpendicular to the third clamping plate 312, and the end face of the slope plate 8 away from the fourth mounting plate 311 coincides with the end face of the third clamping plate 312 that abuts against the steel plate shear wall 4. This design can better fit the surface of the steel plate shear wall 4, locate the joints between the steel plate shear walls 4, and enhance the fixing effect. In this embodiment, a welding groove 9 is opened in the middle of the end face of the third clamping plate 312 that abuts against the steel plate shear wall 4 for the joint between two steel plate shear walls 4 to pass through, which facilitates the subsequent welding of the joint between the steel plate shear walls 4.

[0036] The specific operating steps of this utility model are as follows: First, install the positioning and fixing device 3 on the edge of the installed steel plate shear wall 4. Specifically, place two clamping pieces 31 against the two ends of the steel plate shear wall 4 respectively, and pass the two first bolts 32 through the mounting hole of one clamping piece 31, the tie hole 6 on the edge of the steel plate shear wall, and the mounting hole of the other clamping piece 31 respectively, and lock them with nuts so that a gap is formed between the two third clamping plates 312 for the insertion of another steel plate shear wall 4; then, install two adjusting devices 1 symmetrically on the steel columns 5 on both sides. Specifically, install the adjusting device 1 on the steel column 5 through the mounting groove, and then tighten the steel column 5 with the locking bolt 12. At this time, the washer 7 at one end of the adjusting screw 2 and the steel plate shear wall 4 are engaged. The first steel plate shear wall 4 is brought into contact with the second steel plate shear wall 4. Then, the next steel plate shear wall 4 is hoisted using a vertical transport device and inserted into the gap between the two installed third clamping plates 312. The limiting effect of the slope plate 8 and the third clamping plates 312 positions the steel plate shear wall 4. The verticality of the steel plate is then adjusted by rotating the adjusting screws 2 on both sides of the steel plate shear wall 4. After adjustment, the adjusting screws 2 are tightened. Then, two more first bolts 32 are passed through the mounting holes of one clamping member 31, the tie holes 6 on the edge of this steel plate shear wall, and the mounting holes of another clamping member 31, and locked with nuts. Following the above steps, multiple positioning and fixing devices 3 are installed on the weld between the two steel plate shear walls 4, thus completing the installation and fixing of the steel plate shear wall 4. Finally, welding is performed according to the welding sequence of the steel plate shear wall 4 welds. The positioning and fixing devices 3 are equipped with welding channels, enabling through welding of the steel plate shear wall 4. After welding, the adjusting device 1 and the positioning and fixing devices 3 can be removed.
