A steel abutment assembly is arranged inside the lower part of the prefabricated concrete body. The top end of the vertical abutment steel protrudes above the upper surface of the prefabricated concrete body, and the bottom end is inserted into the steel abutment assembly. When the upper and lower two layers of full prefabricated shear wall plates are fixed in abutment with each other, the top end of the vertical abutment steel of the lower layer is inserted into the steel abutment assembly of the upper layer, and is fixed in abutment with the bottom end of the vertical abutment steel of the upper layer.

[0029] The present invention will be further described below with reference to the accompanying drawings: The present invention will be further described below through specific embodiments, but it is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0030] Example 1, as Figures 1-2 As shown, the assembled integral reinforced cage composite shear wall includes a precast outer leaf wall panel 1, a precast inner leaf wall panel 2, and a straight-line reinforced cage 3. The reinforcing mesh on one side of the straight-line reinforced cage 3 is embedded in concrete to form the precast outer leaf wall panel 1, and the reinforcing mesh on the other side of the straight-line reinforced cage 3 is embedded in concrete to form the precast inner leaf wall panel 2. The precast outer leaf wall panel 1 and the precast inner leaf wall panel 2 are arranged opposite each other to form a cast-in-place cavity 4, which is filled by pouring concrete. Tie bars 5 are provided in the cast-in-place cavity 4, and the two ends of the tie bars 5 are respectively connected to the reinforcing mesh on both sides of the straight-line reinforced cage 3. A hook module 6 is provided on the inner side of the precast inner leaf wall panel 2.

[0031] The straight-line steel cage 3 described in this utility model is prefabricated on an automated production line. Then, the prefabricated outer leaf wall panel 1 and prefabricated inner leaf wall panel 2 are poured with concrete on a fixed mold. The prefabricated outer leaf wall panel 1 and prefabricated inner leaf wall panel 2 form a cast-in-place cavity 4. Tie bars 5 connect the prefabricated leaf panels on both sides to form a whole, ensuring safety and durability. With the presence of the cast-in-place cavity 4, the wall of the same width and height is about half the weight of a conventional shear wall, making on-site hoisting easier. This solves and optimizes the problem of slow installation speed, high installation difficulty, and inefficiency caused by the excessive weight of traditional prefabricated concrete shear wall components.

[0032] During subsequent construction, reinforcing bars can be inserted into the cast-in-place cavity 4, followed by pouring concrete into the cavity 4 to connect the upper and lower walls into a whole. This increases the joint surface of the vertical connection method for precast composite shear walls, making the connection method very reliable. Furthermore, because the dimensions inside the cavity are much larger than the space required for inserting reinforcing bars, construction is easier during installation. The large cavity space facilitates observation, ensuring that the grout fills the cavity completely, thus guaranteeing construction quality.

[0033] Example 2, as Figures 1-2 As shown, the assembled monolithic reinforced cage composite shear wall includes a precast outer leaf wall panel 1, a precast inner leaf wall panel 2, and a straight-line reinforced cage 3. The reinforcing mesh on one side of the straight-line reinforced cage 3 is embedded in concrete to form the precast outer leaf wall panel 1, and the reinforcing mesh on the other side of the straight-line reinforced cage 3 is embedded in concrete to form the precast inner leaf wall panel 2. The precast outer leaf wall panel 1 and the precast inner leaf wall panel 2 are arranged opposite each other to form a cast-in-place cavity 4, which is filled with poured concrete. Tie bars 5 are installed within the cast-in-place cavity 4, with both ends of the tie bars 5 overlapping the reinforcing mesh on both sides of the straight-line reinforced cage 3. A hook module 6 is installed on the inner side of the precast inner leaf wall panel 2. The tie bars 5 are reinforcing bar tie bars.

[0034] The precast leaf slabs are connected by steel bars, improving the overall structural performance and shear resistance; there are no seams between the slabs, eliminating the need for joint treatment and ensuring good waterproofing. Due to the presence of cavities, the walls are lighter and can be hoisted faster, allowing for the use of smaller hoisting equipment under the same conditions, thus meeting the requirements for better, faster, and more environmentally friendly construction.

[0035] Furthermore, referring to Figure 3 The hook module 6 includes a steel plate 6.1, on both sides of which are welded additional steel plate reinforcing bars 6.2 and hook reinforcing bars 6.3. The additional steel plate reinforcing bars 6.2 are embedded in the precast inner leaf wall panel 2. The additional steel plate reinforcing bars 6.2 are all horizontally arranged, and multiple bars are arranged at intervals from top to bottom. This facilitates on-site hoisting.

[0036] Furthermore, the middle part of the additional rib 6.2 of the steel plate is bent to form a protrusion 6.4 that is welded to the steel plate 6.1.

[0037] Furthermore, the steel mesh in the prefabricated outer leaf wall panel 1 includes composite shear wall longitudinal bars 11 and composite shear wall transverse bars 12, which are cross-connected.

[0038] Furthermore, concealed column steel cages 7 are respectively provided at both ends of the straight steel cage 3, and the concealed column steel cages 7 are embedded in the concrete to form concealed columns 8.

[0039] Furthermore, anchor bars 9 are pre-embedded in the concealed column 8 at one end of the straight steel cage 3, and additional end bars 10 are pre-embedded in the concealed column 8 at the other end of the straight steel cage 3. The anchor bars 9 are welded to the wall steel bars, and the additional end bars 10 ensure a reliable connection between the precast inner leaf wall panel 2 of the composite shear wall and the beam formwork.

[0040] Furthermore, it also includes additional reinforcement bars 13 for the partition wall located on the outside of the precast inner leaf wall panel 2, one end of which is embedded in the precast inner leaf wall panel 2. This ensures a reliable connection between the precast inner leaf wall panel 2 and the partition wall of the composite shear wall.

[0041] The assembled integral steel cage composite shear wall of this utility model is characterized by the prefabrication of the straight steel bars in an automated production line, followed by the concrete pouring of prefabricated outer and inner leaf wall panels on a fixed mold. The prefabricated outer and inner leaf wall panels form a cast-in-place cavity, and the tie bars connect the prefabricated leaf panels on both sides to form a whole, ensuring safety and durability.

[0042] The prefabricated integral steel cage composite shear wall described in this utility model has a cast-in-place cavity, and the wall of the same width and height is lighter than that of ordinary shear walls. In addition, the optimized hook module makes it easier to lift on site, which solves and optimizes the problem that the traditional precast concrete shear wall components are too heavy, resulting in slow installation speed, high installation difficulty, and inability to guarantee construction efficiency.

[0043] The prefabricated integral steel cage composite shear wall described in this utility model allows for the insertion of reinforcing bars into the cast-in-place cavity during subsequent construction, followed by the pouring of concrete into the cavity to connect the upper and lower walls into a whole, thus ensuring the quality of construction.

[0044] The assembled integral steel cage composite shear wall described in this utility model has a large cavity space size, which is easy to observe and can ensure that the grouting material fills the cavity, thus ensuring the quality of construction.
