Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a high-rise building prefabricated composite shear wall and a construction method thereof. Background Art

[0002] Shear wall, also known as wind-resistant wall, earthquake-resistant wall or structural wall, is a wall in a house or structure that mainly bears horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. It is also called earthquake-resistant wall and is generally made of reinforced concrete. Prefabricated shear wall is a shear wall formed by prefabricating part or all of the components of the shear wall structure in the factory and then transporting them to the construction site for assembly and connection. This construction method is different from the traditional cast-in-place shear wall. It emphasizes the factory prefabrication of components and efficient assembly on site.

[0003] After searching, the publication number CN222206853U discloses a prefabricated shear wall structure for green buildings, which includes a connecting sleeve embedded in the shear wall and a connecting steel bar embedded in the wall and passed through the connecting sleeve. The bottom wall of the connecting sleeve is penetrated with a through hole for the pre-embedded steel bar to slide through. The outer surface of the connecting sleeve at the lower end is provided with a grouting hole, and the outer surface of the connecting sleeve at the upper end is provided with a grouting hole. The connecting sleeve is provided with a positioning assembly for positioning the pre-embedded steel bar. The positioning assembly includes a connecting rope for connecting to the pre-embedded steel bar and a pulling member for pulling the connecting rope. The upper end of the connecting rope is provided with a through hole and a grouting hole, and the pulling member is arranged outside the shear wall. The present application has the beneficial effect of reducing the time spent on aligning the connecting sleeve with the embedded steel bar below, thereby increasing the installation rate of the prefabricated shear wall.

[0004] The shear walls in the above application need to use positioning components when docking to align the relative positions of the embedded steel bars, and additional components are required to assist in the alignment. Although the alignment time is reduced, the positioning components still need to be installed additionally, and their use does not speed up the installation rate of the shear walls much. Summary of the invention

DETAILED DESCRIPTION

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: Please see attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides a high-rise building assembled composite shear wall, comprising: A foundation 1 is used for leveling and supporting the wall. A placement groove 7 is provided on the top of the foundation 1. The placement groove 7 is used for placing the wall. Two first I-shaped grooves 6 are provided on the bottom of the inner wall of the placement groove 7. Shear wall 3, the shear wall 3 is installed at the bottom of the inner wall of the placement groove 7, the shear wall 3 is used as a structural member to resist lateral force, the left and right sides of the shear wall 3 are provided with grouting grooves 12, the top and bottom of the shear wall 3 are provided with connecting grooves 10, the top of the inner wall of the bottom connecting groove 10 is fixedly connected with an alignment block 14, and the front side of the alignment block 14 is provided with a through groove 15; A limiting mechanism, which is used to limit the position of the shear wall 3, comprises a limiting seat 9, and a sliding column 8 is fixedly connected to the inner wall of the limiting seat 9; The column mechanism is used to connect the foundation 1 with the shear wall 3. The column mechanism includes two first I-shaped grooves 6 and two second I-shaped grooves 11. An I-shaped column 4 is arranged between the upper and lower adjacent first I-shaped grooves 6 and second I-shaped grooves 11.

[0021] The foundation 1 is the basic part of the assembled combined shear wall, and its main function is to level and support the wall. The placement groove 7 on the top is used to place the shear wall 3, and the two first I-shaped grooves 6 opened at the bottom of the inner wall of the placement groove 7 cooperate with the column mechanism to achieve a stable connection between the foundation 1 and the shear wall 3, thereby enhancing the stability of the entire structure; The shear wall 3 is a key structural member for resisting lateral force. The grouting grooves 12 on the left and right sides and the reinforcing steel bars 5 arranged inside can effectively enhance the connection strength between the shear walls after grouting. When the concrete is poured into the grouting grooves 12, it forms a whole with the reinforcing steel bars 5 and bears the force together, thereby improving the shear resistance of the wall and further enhancing the seismic performance of the entire structure. The filling cavity 13 at the center of the inner wall is filled with a polyester fiber sound insulation board, which not only does not affect the strength of the wall structure, but also has a good sound insulation effect. The principle is that there are a large number of tiny pores inside the polyester fiber sound insulation board, which can effectively absorb and reflect sound, reduce sound propagation, and provide a quieter environment inside the building; The connecting grooves 10 at the top and bottom and the alignment block 14 and the through grooves 15 at the top of the inner wall of the bottom connecting groove 10 facilitate alignment and connection with other components during construction and installation, thereby improving construction efficiency and installation accuracy. The through-hole grooves 2 on the surface facilitate construction workers to observe the docking condition of the shear wall and ensure construction quality. The sliding column 8 on the inner wall of the limiting seat 9 in the limiting mechanism is used in conjunction with the positioning rope and the through hole groove 2 and the through groove 15 to limit the position of the shear wall 3 when it is installed. By passing the rope through these parts and interacting with the sliding column 8, during the descent of the crane equipment, the foundation 1 and the shear wall 3 can be quickly and accurately aligned by simply pulling the rope, which effectively reduces errors during the installation process.

[0022] Compared with the method that requires additional installation of complex positioning components, the operation process is simplified and the installation efficiency is improved. In addition, this connection method is easy to operate, which can effectively shorten the construction time and speed up the overall construction progress of high-rise buildings.

[0023] The shear wall 3 further includes reinforcing steel bars 5 , which are arranged in the grouting grooves 12 . The reinforcing steel bars 5 are fixedly connected to the grouting grooves 12 . The reinforcing steel bars 5 are used to enhance the connection strength when cement is poured into the grouting grooves 12 .

[0024] A filling cavity 13 is opened at the center of the inner wall of the shear wall 3 . The filling cavity 13 is used to fill functional materials. The filling cavity 13 is filled with a polyester fiber sound insulation board.

[0025] The placement groove 7 is located at the bottom of the inner wall of the limiting seat 9, and the placement groove 7 is fixedly connected to the limiting seat 9.

[0026] The two first I-shaped grooves 6 are located between the two connecting grooves 10 . The two first I-shaped grooves 6 are both opened on the shear wall 3 . The two second I-shaped grooves 11 are opened at the bottom of the inner wall of the placement groove 7 .

[0027] The I-shaped column 4 passes through the top connecting groove 10 , the first I-shaped groove 6 , the bottom connecting groove 10 and the second I-shaped groove 11 in sequence.

[0028] The installation of the I-shaped column 4 is an important link in strengthening the structural connection. It passes through each connecting groove and the I-shaped groove in turn until it is nailed into the ground, completing the connection between the foundation 1 and the shear wall 3, further improving the stability and integrity of the entire structure, enabling each part to work together to resist the various loads borne by the high-rise building. The principle is to form a stable spatial force system, effectively transfer and distribute the load, and ensure the safety and reliability of the building.

[0029] A through hole groove 2 is provided on the surface of the shear wall 3 , and the through hole groove 2 is used to observe the butt joint of the shear wall 3 .

[0030] Please see attached Figure 5 A method for constructing a high-rise building assembled composite shear wall comprises the following steps: Step 1, production of precast concrete wall panels: precast concrete foundation 1 and shear wall 3 are manufactured according to requirements, and a first I-shaped groove 6, a connecting groove 10, and a second I-shaped groove 11 are reserved on the foundation 1 and the shear wall 3, and a filling cavity 13 is set in the shear wall 3; Step 2, on-site installation: transport the precast concrete foundation 1 and the shear wall 3 to the construction site, level the ground, first lift the foundation 1 and put it in place by the crane equipment, then lift the shear wall 3 by the crane equipment, and then use the positioning rope to pass through the through-hole groove 2, and pass the rope through the through-hole groove 15, and further pull the rope downward until the rope passes through the sliding column 8, and then the rope comes out from the through-hole groove 2 again. As the crane equipment descends, the shear wall 3 is limited, and the foundation 1 and the shear wall 3 can be aligned by just pulling the rope; Step 3: Then, pull out the rope to complete the docking work of a shear wall 3, and then insert the I-shaped column 4 through the top connecting groove 10 in sequence and enter the first I-shaped groove 6, and then the I-shaped column 4 enters the bottom connecting groove 10 until it passes through the second I-shaped groove 11 on the foundation 1, completing the connection between the foundation 1 and the shear wall 3, and repeat the above steps 2-3 to complete the assembly of the shear wall 3; Step 4, pour concrete into the grouting groove 12 in the shear wall 3, the concrete flows along the grouting groove 12, and the concrete gradually fills the two connecting grooves 10 and the two grouting grooves 12. After waiting for solidification, the reinforcing steel bars 5 can be used to strengthen the connection between the two shear walls 3.

[0031] In step 4, when pouring concrete, a vibration device is used to vibrate the concrete so that the concrete is poured evenly in the shear wall 3, and the concrete is observed through the through hole groove 2.

[0032] Embodiment 2: The present embodiment differs from the above-mentioned embodiment in that the present embodiment can also be used in the construction of low-rise housing. The I-shaped columns (4) are sequentially passed through the connecting groove (10) at the top and then enter the first I-shaped groove (6). Then, the I-shaped columns (4) enter the connecting groove (10) at the bottom until they pass through the second I-shaped groove (11) on the foundation (1). The I-shaped columns (4) are continuously nailed downward into the ground, thereby completing the connection between the foundation (1), the shear wall (3) and the ground.
