[0031] Reference Figure 1 and 3 A first operating hole 12 is provided at the top of the first barrel 11, and a first mounting hole 13 is provided at the bottom of the first barrel 11. The first mounting hole 13 is used to mount the first bolt, and the first operating hole 12 is used to provide an operating space when mounting / removing the first bolt; for example, a worker passes the head of an electric screwdriver through the first operating hole 12 and inserts it into the inner cavity of the first barrel 11 to drive the first bolt to rotate.

[0032] Reference Figure 1 , 45, a second operating hole 24 is provided at the top of the second barrel 21, and a second mounting hole 25 is provided at the bottom of the second barrel 21. The second mounting hole 25 is used to mount the second bolt, and the second operating hole 24 is used to provide an operating space when mounting / removing the second bolt; for example, a worker passes the head of an electric screwdriver through the second operating hole 24 and inserts it into the inner cavity of the second barrel 21 to drive the second bolt to rotate.

[0033] Reference Figure 1 , 2 , 4, 5, 6, the end of the second barrel 21 away from the third barrel 31 is fixedly installed with a vertical plate 22 (for example, fixedly connected by welding or fixedly connected by bolts). A rotating roller 26 is installed in the inner cavity of the second barrel 21, and the circumferential surface of the rotating roller 26 can rotate, for example: the two ends of the integral rotating roller 26 are respectively rotatably connected to the inner wall of the second barrel 21 (for example, connected by bearings); or the split rotating roller 26 includes an inner and outer ring body connected by balls and can rotate with each other, and the end of the inner ring body is fixedly connected to the inner wall of the second barrel 21 (for example, fixedly connected by bolts), and the outer ring body can rotate relative to the inner ring body. The rotating roller 26 is used to reduce friction when pulling the cable 4.

[0034] Reference Figure 1 , 2 As shown in FIG7 , the third barrel 31 is a self-locking telescopic rod, such as a screw-on telescopic rod.

[0035] Reference Figure 3 , the cross section of the first barrel 11 is a regular quadrilateral; Figure 4 The cross section of the second barrel 21 is a regular quadrilateral. The cross section of the middle part of the third barrel 31 is circular. The cross sections of the ends of the third barrel 31 are all regular quadrilaterals, so that the two ends of the third barrel 31 are hinged with the first barrel 11 and the second barrel 21 respectively.

[0036] Reference Figure 1 , 2 , 4, 5, 6, the vertical plate 22 is vertically arranged with respect to the upper surface of the second barrel 21. The vertical plate 22 is fixedly connected with the upper surface of the second barrel 21 by the reinforcing ribs 23. The reinforcing ribs 23 and the vertical plate 22 are fixed by welding, and the reinforcing ribs 23 and the upper surface of the second barrel 21 are fixed by welding to improve the impact resistance of the vertical plate 22 and improve the service life of the vertical plate 22.

[0037] Reference Figure 4 and 5 There are two reinforcing ribs 23, and the two reinforcing ribs 23 are respectively arranged on both sides of the second operating hole 24 to ensure that the second operating hole 24 is exposed to the outside, to prevent the reinforcing rib 23 from blocking the second operating hole 24, and to further prevent the reinforcing rib 23 from hindering the operating tool (such as an electric screwdriver) from passing through the second operating hole 24.

[0038] Reference Figure 3 and 4 The first operation hole 12 and the second operation hole 24 are both regular quadrilaterals to ensure that the area of ​​the first operation hole 12 is increased as much as possible while adapting to the reinforcing ribs 23 on both sides. The first installation hole 13 and the second installation hole 25 are both circular to adapt to the installation of the first bolt and the second bolt.

[0039] Reference Figure 3 and 4 The first operating hole 12 is located directly above the first mounting hole 13; the second operating hole 24 is located directly above the second mounting hole 25 to ensure convenient operation for the staff.

[0040] The rotating roller 26 is a variable diameter roller, and the diameter of the middle part of the rotating roller 26 is smaller than the diameter of the end part; when the cable 4 is overlapped or wrapped around the surface of the rotating roller 26, the cable 4 is located at the position with the smallest diameter in the middle part of the rotating roller 26, so as to prevent the cable 4 from moving into the gap between the end part of the rotating roller 26 and the inner wall of the second barrel 21, thereby improving the functional reliability of the utility model and reducing the failure rate.

[0041] Reference Figure 5 and 6 The bottom end of the vertical plate 22 is provided with an inclined surface 221 or an arc surface. When the cable 4 is crimped at the bottom end of the vertical plate 22, the inclined surface 221 / arc surface is used to reduce the wear of the cable 4 and improve the service life of the utility model. The inclined surface 221 and the arc surface are both formed by bending, which is convenient for manufacturing.

[0042] Reference Figure 8 The first barrel 11 and the third barrel 31 are hinged at the side wall, and the second barrel 21 and the third barrel 31 are hinged at the side wall, providing space for the movement of the cable 4.

[0043] Reference Fig. 9 The third barrel 31 includes a first outer barrel 311, a second outer barrel 312 and an inner barrel 313. A first convex ring 3111 is provided on the inner surface of the first outer barrel 311, and the first convex ring 3111 is in the shape of a circular ring protruding inwards; a second convex ring 3121 is provided on the inner surface of the second outer barrel 312, and the second convex ring 3121 is in the shape of a circular ring protruding inwards; a plurality of alternately arranged external threads 3131 are provided on the outer surface of the inner barrel 313, and a first internal thread is provided on the inner surface of the first convex ring 3111, and a second internal thread is provided on the inner surface of the second convex ring 3121. When the first internal thread is engaged with one section of the external thread 3131 and the second internal thread is engaged with one section of the external thread 3131, the length of the third barrel 31 is fixed. When one or more of the first outer barrel 311, the second outer barrel 312 and the inner barrel 313 are rotated until the first internal thread is disengaged from the external thread 3131 or the second internal thread is disengaged from the external thread 3131, the staff can quickly extend and retract the third barrel 31.

[0044] Reference Figure 1 and 7 The working steps and principles of the utility model are as follows: ① The utility model is installed on the upper surface of the floor 02 by the first bolt and the second bolt, so that the vertical plate 22 is flush with the end of the trough body for placing the shear wall 0 on the floor 02; ② Use a lifting device (such as a crane and a sling 01) to lift the shear wall 0 and move it to a position close to the top of the trough body; ③ Pass one end of the cable 4 through the gap between the rotating roller 26 and the lower surface of the inner cavity of the second cylinder body 21, and then tie it to the protruding steel bar 001 at the bottom of the shear wall 0; ④ Use the lifting equipment to slowly lower the shear wall 0, and at the same time tighten the other end of the cable 4. ⑤ Untie or cut the cable 4, remove the second bolt (the first connector 1 remains in position and the first bolt remains installed), and flip the second connector 2 and the telescopic assembly 3 upward; ⑥ Extend the telescopic assembly 3, continue to flip the second connector 2 upward until the second connector 2 is in a vertical state, and then install the third bolt in the second mounting hole 25. The third bolt is detachably connected to the embedded nut on the side wall of the shear wall 0 through a thread to achieve side support.

[0045] Reference Figure 2 In step ④, the other end of the cable 4 passes through the telescopic assembly 3 and the first connecting member 1 and then passes through the first barrel 11. The other end of the cable 4 is tightened by manpower or equipment (such as a winch). Figure 6 During step ④, the other end of the cable 4 passes through the second operating hole 24, and the other end of the cable 4 is tightened by manpower or equipment (such as a winch).

[0046] Reference Figure 7 and 9 When the first connecting member 1 is connected to the floor 02 and the second connecting member 2 is connected to the side wall of the shear wall 0, since the second connecting member 2 cannot rotate, the telescopic assembly 3 is in a length locked state to achieve self-locking.

[0047] The utility model has a simple structure, reliable functions, and convenient loading and unloading. The shear wall 0 is pulled to the desired position by using the second connecting member 2 and the cable 4, thereby improving the installation accuracy and optimizing the project quality. At the same time, the second connecting member 2 and the telescopic assembly 3 can be flipped up and used as side supports, further simplifying the subsequent support construction steps and improving the overall construction efficiency.
