1. after the lower layer steel concrete composite pipe 1 is installed and fixed, the tower crane hoists the upper layer steel concrete composite pipe 2 in place, so that the upper connecting flange plate 19 at the lower end part of the upper layer steel concrete composite pipe 2 is butted with the lower connecting flange plate 24 at the upper end part of the lower layer steel concrete composite pipe 1, and the specific butt joint process is as follows: when the upper connecting flange plate 19 and the lower connecting flange plate 24 basically correspond up and down, because two guide slope surfaces are arranged at the outer sides of the guide blocks 26 which protrude downwards from the lower surface of the upper connecting flange plate 19, the lower ends of the guide blocks 26 can easily enter the rectangular holes 25 in the lower connecting flange plate 24, the left guide slope surface, the front guide slope surface and the rear guide slope surface at the periphery of the guide block 26 at the left side are respectively matched with the guide slope surfaces on the first plate 27, the second plate 28 and the third plate 29 at the left side, after the right guide slope surface, the front guide slope surface and the rear guide slope surface at the periphery of the guide block 26 at the right side are respectively matched with the guide slope surfaces on the first plate 27, the second plate 28 and the third plate 29 at the right side, the upper connecting flange plate 19 and the lower connecting flange plate 24 are in butt joint neatly, and the upper layer steel concrete composite pipe 2 and the lower layer steel concrete composite pipe 1 are automatically aligned up and down without horizontal deviation rectification adjustment.
Then, installing temporary positioning devices on the front side and the rear side of the upper-layer steel concrete composite pipe 2 and the lower-layer steel concrete composite pipe 1, determining that the upper-layer steel concrete composite pipe 2 and the lower-layer steel concrete composite pipe 1 are vertically aligned and are ensured to be on the same vertical plane, pressing the pressing rod 10 downwards, pulling the upper pull rod assembly 11 downwards through a front pull hole on the pressing rod 10 of a set of pressing type positioners on the front side, pulling the lower pull rod assembly 12 upwards through a rear pull hole on the pressing rod 10, and basically locking the pressing rod 10 when the lower end side part of the upper pull rod assembly 11 is contacted with the upper end side part of the lower pull rod assembly 12;
the set of push type locators on the rear side are operated in the same push mode. Therefore, the upper fixing piece 3 and the lower fixing piece 4 are connected into a whole after being tensioned by the upper pull rod assembly 11 and the lower pull rod assembly 12, at the moment, if the upper layer steel concrete composite pipe 2 and the lower layer steel concrete composite pipe 1 have small deviation in verticality, a wrench can be used for clamping the internal thread sleeve 15 or the turnbuckle to rotate for fine adjustment until the vertical planes of the upper layer steel concrete composite pipe 2 and the lower layer steel concrete composite pipe 1 are kept consistent, then a tower crane can be controlled to loosen the upper layer steel concrete composite pipe 2, the tower crane continues to hoist other assembly type components, and then a welding gap between the upper connecting flange plate 19 at the lower end part of the upper layer steel concrete composite pipe 2 and the lower connecting flange plate 24 at the upper end part of the lower layer steel concrete composite pipe 1 is welded. In the welding process, the tower crane can be used for other hoisting operation, so that the construction efficiency is improved.
2. Two positioning grooves 9 are formed in the supporting plate 7, and the hanging positions of the upper pull rod assembly 11 and the lower pull rod assembly 12 and the positioning grooves 9 can be adjusted, so that the pressing force operation of the pressing rod 10 is facilitated.
3. After the welding between the upper connecting flange plate 19 at the lower end part of the upper layer steel concrete composite pipe 2 and the lower connecting flange plate 24 at the upper end part of the lower layer steel concrete composite pipe 1 is finished, the temporary positioning device is disassembled, and the next butt joint of the upper layer steel concrete composite pipe 2 and the lower layer steel concrete composite pipe 1 is carried out and then the temporary positioning device is installed for use. The upper fixing piece 3 and the lower fixing piece 4 are installed by the aid of the stud bolts, and the upper fixing piece and the lower fixing piece are rapid, convenient and reusable.
4. The invention makes the construction process of the shear wall become simple, and then improve the construction progress, the steel-concrete composite pipe is formed by bending the steel plate with the reinforcing rib 20 on the inner and outer surfaces, the contact area of the steel and the concrete is increased by the tie bar 17 to enhance the strength and the integrity of the rectangular cylindrical structural steel plate 16, the reinforcing mesh 18 which is not in contact with the outer side wall of the rectangular cylindrical structural steel plate 16 is arranged on the outer side of the periphery of the rectangular cylindrical structural steel plate 16, so that the combination of the outer concrete wrapped on the outer side of the rectangular cylindrical structural steel plate 16 and the rectangular cylindrical structural steel plate 16 is firmer, and the anti-deformation performance of the steel-concrete composite pipe is improved.
5. The guide block 26 not only serves as a guide when the steel plate is dropped and butted, but also serves to reinforce the strength of the lower port of the rectangular tubular steel plate. The bottom plate 30 functions to reinforce the strength of the upper port of the rectangular tubular-structured steel plate. The bottom plate 30 is provided with a lower pouring through hole 31 which is vertically corresponding to an upper pouring through hole 32 formed in the guide block 26, and when concrete is poured in the inner part, the effect of improving the connection strength between the upper layer steel concrete composite pipe 2 and the lower layer steel concrete composite pipe 1 can be achieved through the concrete.
