Detailed Implementation

[0027] 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 some embodiments of the present invention, and not all embodiments. 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.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example: Refer to Figures 1-6 A steel tube bundle composite shear wall, comprising,

[0030] The precast wall panel 1 has a splicing end A and a splicing end B at both ends, and the splicing end A is connected to the splicing end B of another adjacent precast wall panel 1.

[0031] The guide connection assembly includes a first guide part disposed at splice A end and a second guide part disposed at splice B end. The first guide part includes a casting pipe 2 for stabilizing splice A end, and the casting pipe 2 is connected to splice A end. The second guide part includes a connecting groove 3 that has a positioning function relative to the casting pipe 2, and the casting pipe 2 is connected to the connecting groove 3. A connector is provided between the first guide part and the second guide part.

[0032] The precast wall panel 1 is divided into a precast section and a post-construction section. The precast section is used to securely splice end B and position and splice end A, while the post-construction section is used to securely splice end A.

[0033] This invention assembles a steel pipe bundle shear wall by correspondingly setting splicing ends A and B on precast wall panels 1, and connecting splicing ends A on one precast wall panel 1 to splicing ends B on an adjacent precast wall panel 1. A guide connection component is provided at the connection point of the two precast wall panels 1, and splicing ends A are securely connected using a pouring pipe. Simultaneously, a connecting groove 3 on the second guide section provides rapid guidance relative to the pouring pipe 2, and the pouring pipe 2 is connected to the connecting groove 3. This improves the splicing speed of the precast wall panels 1, accelerates assembly construction efficiency, and allows for pouring into the connecting groove 3 via the pouring pipe 2. The concrete is used to fix the whole structure. Combined with the reinforcement of the first and second guide parts by the connectors, the connection strength at the joint of splice A end and splice B end is improved, reducing the possibility of fracture at the joint of the combined shear wall. Furthermore, the precast wall panel 1 is provided with a precast part that can simultaneously stabilize splice B end and position the splice A end, thereby improving the construction speed of the precast wall panel 1 and accelerating the construction efficiency. At the same time, the subsequent masonry part stabilizes the splice A end that is positioned and connected to the precast part, thereby improving the structural strength of the overall steel pipe bundle shear wall and enhancing the bending and shear resistance of the shear wall.

[0034] Furthermore, the prefabricated part includes a base 4, and truss reinforcement 5 is fixedly connected inside the base 4. The post-construction part includes a number of rectangular tubes 6 fixedly connected to the base 4 at one end. The rectangular tubes 6 are arranged sequentially from left to right. The outer periphery of the number of rectangular tubes 6 is covered with a post-construction concrete slab 7. The post-construction concrete slab 7 is integrally formed with the base 4. The casting pipe 2 is located at the other end of the rectangular tubes 6 away from the base 4. The casting pipe 2 is connected to the number of rectangular tubes 6.

[0035] In this technical solution, before pouring to form the base 4, the truss reinforcement 5 is tied and fixed in the mold, and then the rectangular tubes 6 are arranged in sequence on one side of the truss reinforcement 5. Then, concrete is poured in the mold to fix the truss reinforcement 5 and the rectangular tubes 6 together. After integral molding, the concrete slab 7 and the base 4 are built, and the end of the rectangular tube 6 away from the base 4 is connected to the pouring pipe 2 so as to facilitate the later pouring of concrete into the rectangular tube 6.

[0036] In one embodiment of the present invention, a snap-fit ​​plate 17 is fixedly connected to one side of a rectangular tube 6, and an installation groove adapted to the snap-fit ​​plate 17 is opened on one side of another rectangular tube 6 adjacent to the snap-fit ​​plate 17. By inserting and cooperating the snap-fit ​​plate 17 with the installation groove, the connection strength and assembly efficiency of several rectangular tubes 6 are improved. Furthermore, when the pouring pipe 2 pours concrete into the rectangular tube 6, the connection strength between several rectangular tubes 6 is increased, thereby improving the stress in the shear wall and ensuring the integrity of the precast wall panel 1.

[0037] Furthermore, the splicing end A includes a number of connecting holes 8 opened on the end of the post-constructed concrete slab 7 away from the base 4. The number of connecting holes 8 is the same as that of the rectangular tube 6 and they correspond one-to-one. The connecting holes 8 are connected to the rectangular tube 6.

[0038] The splicing end B includes several connecting steel bars 9 fixed to one end of the preset base 4 away from the rectangular tube 6. The number of connecting steel bars 9 is the same as the number of connecting holes 8 on the adjacent post-constructed concrete slab 7 and they correspond one-to-one.

[0039] In this technical solution, when a precast wall panel 1 is spliced ​​with another adjacent precast wall panel 1, the connecting steel bar 9 is inserted into the connecting hole 8, and then the concrete is poured simultaneously using the pouring pipe 2 to connect the steel bar 9, the connecting hole 8 and the rectangular tube 6, thereby improving the assembly efficiency of the composite shear wall. It is also understood that the diameter of the connecting hole 8 is larger than the diameter of the connecting steel bar 9 to ensure that the concrete can smoothly enter the rectangular tube 6 during pouring.

[0040] Furthermore, the first guide section also includes several supporting shells 10, which are fixed to the end face of the post-constructed concrete slab 7 and communicate with the connecting holes 8. The number of supporting shells 10 and connecting holes 8 are the same and correspond one-to-one. One end of the pouring pipe 2 passes through several supporting shells 10 and communicates with them. The end of the connecting steel bar 9 away from the preset base 4 extends into the connecting hole 8.

[0041] Reference Figure 4 , Figure 6 The supporting shell 10 covers the outside of the connecting hole and is connected to the connecting hole 8. At the same time, one end of the pouring pipe 2 extends into the supporting shell 10 and is connected to the supporting shell 10. It can be understood that not only can the supporting shell 10 be used to position and lock the connecting steel bar 9 to improve the structural strength of the connection after pouring, but also the connection and fixation of the precast wall panel 1 can be achieved simply by extending the connecting steel bar 9 into the supporting shell 10 and then pouring the supporting shell 10, which improves the construction efficiency. When the pouring pipe 2 is poured, the concrete enters the supporting shell 10 and then enters the rectangular pipe 6, and the supporting shell 10, the connecting steel bar 9 and the rectangular pipe 6 are poured and fixed together. This not only facilitates the pouring and construction of the combined shear wall and improves the construction efficiency, but also, after the concrete is poured and solidified, the supporting shell 10 and the pouring pipe 2 are integrally formed, so that the first guide part set for supporting the splicing end A has strong internal stress, forming a high-strength structure at the splicing position of the precast wall panel 1, effectively improving the bending and shear resistance of the shear wall connection.

[0042] Furthermore, a number of bases 11 are fixedly connected to one end of the pre-built base 4 away from the post-constructed concrete slab 7. A connecting groove 3 is opened on the side of the base 11 away from the pre-built base 4, and the base 11 is spaced apart from the adjacent supporting shell 10. A guide groove 12 is opened on the side wall of the base 11, and the pouring pipe 2 is slidably connected to the guide groove 12. A pouring hole is opened at one end of the pouring pipe 2 that extends into the connecting groove 3.

[0043] Furthermore, the supporting shell 10 has a trapezoidal structure, with the smaller end of the supporting shell 10 facing the connecting steel bar 9, and the length of the base 11 extending out of the preset base 4 is less than the length of the connecting steel bar 9 extending out of the preset base 4.

[0044] Reference Figures 2-3 With the supporting shell 10 and the base 11 spaced apart, the trapezoidal guide end of the supporting shell 10 helps the base 11 to quickly extend into the gap of the supporting shell 10. At the same time, the connecting steel bar 9 extends into the supporting shell 10 to speed up the assembly efficiency. Meanwhile, the pouring pipe 2 extends into the connecting groove 3 opened on the base 11. The guide groove 12 limits the pouring pipe 2, so that the precast wall panels 1 have the stability of being plugged and fixed during pouring, ensuring the smooth progress of the pouring process and further improving the construction efficiency.

[0045] Furthermore, the connector includes two oppositely arranged connecting plates 13. One end of the connecting plate 13 is fixedly connected to the outer wall of the post-constructed concrete slab 7, and the other end of the connecting plate 13 is slidably connected to the adjacent preset base 4. The two connecting plates 13 cooperate to form a pouring groove that is adapted to the first guide part and the second guide part, and the pouring pipe 2 is located in the pouring groove.

[0046] Reference Figure 1 The connecting plates 13 are arranged opposite each other to form a pouring groove. During pouring, baffles (not shown in the figure) can be selectively set to block both sides of the pouring groove. At the same time, a hole connected to the pouring pipe 2 is opened on one side of the baffle for pouring concrete. During the pouring process, the concrete is sequentially introduced into the supporting shell 10, the rectangular tube 6, and the connecting groove 3 through the pouring pipe 2. Finally, under the cooperation of the pouring groove formed by the connecting plates 13 and the baffle, the concrete is poured into a casting block that is compatible with the precast wall panel 1, forming an integral composite shear wall. This process not only improves construction efficiency, but also the added supporting shell 10 and connecting groove 3 further improve the bond strength of the concrete to the two precast wall panels 1 and strengthen the bending shear force at the connection.

[0047] Furthermore, a reinforcing member is provided on the connecting plate 13, which is used to lock the connecting plate 13 and the second guide portion.

[0048] Furthermore, the reinforcing member includes a locking bolt 14 disposed in the connecting groove 3, and the connecting plate 13 has a through hole corresponding to the locking bolt 14. One end of the locking bolt 14 is threaded through the through hole and connected to a locking nut 15.

[0049] Reference Figure 5 By using the reinforcing member to lock the connecting plate 13 and the base 11, the structural strength of the connection of the precast wall panel 1 is further improved. At the same time, the concrete pouring reinforces the locking bolt 14, further increasing the contact area between the concrete and the connection structure. Furthermore, the locking bolt 14 and the locking nut 15 apply prestress by pressing the connecting plate 13 and the base 11. During the concrete pouring and solidification process, the expansion force generated by the concrete solidification is mutually canceled by the reaction of the prestress, effectively reducing the possibility of the connecting plate 13 bulging outward or even being damaged due to internal stress.

[0050] In one embodiment of the present invention, reference is made to Figure 5 A support plate 16 is fixedly connected to the inner wall of the connecting plate 13 corresponding to the base 11. The support plate 16 slides in contact with the outer wall of the base 11. One end of the locking bolt 14 extends out of the base 11 and passes through the support plate 16 and the connecting plate 13.

[0051] The working process of this embodiment is as follows:

[0052] The truss reinforcement 5 is tied and fixed inside the mold, and then rectangular tubes 6 are arranged sequentially on one side of the truss reinforcement 5. Concrete is then poured into the mold to integrally form the truss reinforcement 5 and rectangular tubes 6 into a precast wall panel 1. After the mold is disassembled, the precast wall panel 1 is transported to the installation site by means of hoisting or other methods. The trapezoidal guide end of the supporting shell 10 helps the base 11 to quickly extend into the gap of the supporting shell 10. At the same time, the connecting steel bar 9 extends into the supporting shell 10 to speed up the assembly efficiency. Meanwhile, the pouring pipe 2 extends into the connecting groove 3 opened on the base 11. The guide groove 12 is used to limit the pouring pipe 2, and the connecting plate 13 is used to form a pouring groove. During pouring, a baffle can be selectively set to block both sides of the pouring groove. At the same time, a hole connected to the pouring pipe 2 is opened on one side of the baffle for pouring concrete. During the pouring process, the concrete is sequentially introduced into the supporting shell 10, the rectangular tube 6, and the connecting groove 3 through the pouring pipe 2, and finally poured into a pouring block that is compatible with the precast wall panel 1 under the cooperation of the pouring groove formed by the connecting plate 13 and the baffle, thus forming an integral composite shear wall.
