[0002] In the modern construction industry, in order to improve construction efficiency and building quality, prefabricated components are used more and more widely; especially in residential and commercial construction projects, prefabricated walls and prefabricated panels are highly favored due to their good structural performance and rapid assembly characteristics; in the actual construction process, the connection between prefabricated walls and prefabricated panels often relies on manual adjustment and visual inspection by workers, especially for the connection between the bottom of the prefabricated wall and the dowels on the prefabricated panel. The accuracy requirements are extremely high.

[0017] A construction method for a prefabricated wall structure of an assembled house comprises the following steps:

[0018] S1. Construction preparation: Before construction, carefully check the quality of precast walls and precast panels to ensure that there are no damage or defects and confirm that the sleeves of the precast walls and the dowels on the precast panels match in size;

[0019] S2. Install the positioning pieces: Screw the fixing tubes of the two sets of positioning pieces into the side tubes at both ends of the prefabricated wall according to the design requirements, and ensure that the positioning pieces are correctly installed and can rotate;

[0020] S3. Hoisting prefabricated wall: Use hoisting equipment to steadily hoist the prefabricated wall and position it above the prefabricated board. During this process, the staff will manually assist in adjusting the position to ensure that the positioning plates at both ends of the prefabricated wall can accurately dock with the corresponding dowel bars on the prefabricated board.

[0021] S4. Automatic positioning: When the prefabricated wall is placed in place, the dowels are gently in contact with the positioning plate. As the prefabricated wall slowly descends, the dowels will push the positioning plate upward, triggering the clamp to automatically clamp the dowels. The pressure applied by the clamp to the dowels automatically fine-tunes the position of the prefabricated board, so that the positioning plates at both ends of the prefabricated wall are completely aligned with the corresponding dowel axis, realizing automatic and precise positioning between the prefabricated wall and the prefabricated board;

[0022] S5. Removing the positioning piece: After the prefabricated wall and the prefabricated panel are automatically positioned, the fixing tube is rotated to disengage it from the internal thread sleeve, allowing the entire positioning piece to rise together with the prefabricated wall and enter the side tube;

[0023] S6. Fixing and grouting: After confirming that the prefabricated wall is firmly seated on the prefabricated board, inject concrete or other designated grouting materials into the sleeve through the grouting holes reserved on the top of the prefabricated wall to fill the gap between the prefabricated wall and the prefabricated board to enhance the connection strength between the two. After the grouting is completed, according to the requirements of the grouting material used, give it appropriate time to solidify to complete the installation of the prefabricated wall structure.

[0024] The beneficial effects of the present invention are as follows: through the provided positioning assembly, after the prefabricated wall is hoisted, the worker manually adjusts the dowel rod to connect with the positioning plate, and then controls the crane to drive the prefabricated wall to continue to move down slowly. As the prefabricated wall moves down slowly, the two groups of connection assemblies drive the two groups of clamps to approach each other until they are clamped at the periphery of the corresponding dowel rod; in the process of clamping the dowel rod, the clamp will automatically adjust the position of the prefabricated board by using the thrust of the clamp on the dowel rod, and after the clamps at both ends of the prefabricated wall clamp the corresponding dowel rod, the positioning plates at both ends of the prefabricated wall will coincide with the axis of the corresponding dowel rod, and the middle tube will also automatically coincide with the axis of the corresponding dowel rod, thereby automatically completing the docking of the dowel rod on the prefabricated board with the sleeve of the prefabricated wall, simplifying the docking process, and eliminating the need for workers to bend over and lie on the ground every time they adjust, or to use a mirror to check the docking position and manually fine-tune the position of the prefabricated wall multiple times, thereby improving the overall construction efficiency.

A sleeve is arranged at the bottom of the prefabricated wall 1, and the sleeve includes a side tube 101 at both ends of the prefabricated wall 1 and a middle tube 102 between the side tubes 101, wherein the inner diameter of the side tube 101 is larger than the diameter of the dowel 201, and the inner diameter of the middle tube 102 is adapted to the diameter of the dowel 201; a mounting groove is opened at the bottom of the side tube 101, and an internal threaded sleeve 103 is fixedly arranged in the mounting groove;

[0041] Two sets of positioning members are respectively arranged in two sets of side tubes 101;

[0042] The positioning member includes a hollow fixed cylinder 3, the top of the outer periphery of the fixed cylinder 3 is provided with an external thread that is threadably matched with the internal thread sleeve 103, the outer periphery of the fixed cylinder 3 at the lower side of the internal thread is a smooth surface, a movable plate 4 is rotatably provided at the bottom of the fixed cylinder 3, a center hole 401 is provided in the middle of the movable plate 4, a shaft 10 is slidably provided in the center hole 401, a positioning plate 5 for docking the inserted reinforcing bar 201 is fixedly provided at the bottom of the shaft 10, two groups of clamps 6 for clamping the inserted reinforcing bar 201 are symmetrically provided at the bottom of the positioning plate 5, a rack 7 is provided at the top of the positioning plate 5, teeth are provided at the upper part of the rack 7, and the lower part of the teeth is a smooth surface, a through hole 403 is provided on the movable plate 4, and the rack 7 passes through the through hole 403 to penetrate the movable plate 4 upward;

[0043] Two groups of mounting blocks 801 are symmetrically arranged at the bottom of the movable plate 4, a bidirectional screw rod 8 is rotatably arranged between the two groups of mounting blocks 801, a gear 802 meshing with the rack 7 is rotatably arranged on the mounting block 801 on one side, the gear 802 is fixedly connected to the bidirectional screw rod 8, and connecting components 9 are respectively screwed on the opposite external threads on both sides of the bidirectional screw rod 8, and the two groups of connecting components 9 are respectively connected to the two groups of clamps 6.

[0044] In this embodiment, before the workers hoist the prefabricated wall 1, they first install the two sets of positioning members in the two sets of side tubes 101; specifically, the external threads on the fixing tube 3 of the positioning member are screwed with the internal threaded sleeve 103 in the side tube 101 to complete the installation of the positioning member; after the positioning member is installed, the prefabricated wall 1 is hoisted on the upper side of the prefabricated board 2 by a crane, and the workers manually straighten the prefabricated wall 1 to control the positioning plates 5 at both ends of the prefabricated wall 1 to abut against the corresponding dowels 201, and the docking is completed;

[0045] After the dowel 201 is docked with the positioning plate 5, the crane is controlled to drive the prefabricated wall 1 to continue to move down slowly. As the prefabricated wall 1 moves down slowly, the dowel 201 will push the positioning plate 5 to move up, and the positioning plate 5 will drive the rack 7 to move up. The upward movement of the rack 7 drives the gear 802 to rotate, and the rotation of the gear 802 drives the bidirectional screw rod 8 to rotate, thereby driving the two sets of connecting components 9 on the bidirectional screw rod 8 to approach each other, and the two sets of connecting components 9 drive the two sets of clamps 6 to approach each other until they are clamped on the outer periphery of the corresponding dowel 201;

[0046] In the process of clamping the dowel 201, the clamp 6 automatically adjusts the position of the prefabricated panel 2 by using the thrust of the clamp 6 on the dowel 201. After the clamps 6 at both ends of the prefabricated wall 1 clamp the corresponding dowel 201, the positioning plates 5 at both ends of the prefabricated wall 1 will coincide with the axis of the corresponding dowel 201. At this time, the middle tube 102 will also automatically coincide with the axis of the corresponding dowel 201, thereby automatically completing the docking of the dowel 201 on the prefabricated panel 2 and the sleeve of the prefabricated wall 1.

[0047] Afterwards, as the prefabricated wall 1 continues to move downward, the dowel rod 201 pushes the positioning plate 5 to continue to move upward. During this period, the fixing tube 3 is rotated to make the external thread of the fixing tube 3 move out from the thread of the internal threaded sleeve 103. At this time, the fixing tube 3 and the internal threaded sleeve 103 are disconnected, and the dowel rod 201 will push the positioning piece to move upward into the side tube 101; after the prefabricated wall 1 and the prefabricated plate 2 are connected, grouting is performed into the sleeve through the grouting holes reserved on the prefabricated wall 1 to complete the installation of the prefabricated wall 1 plate.

[0048] Preferably, the clamp 6 includes a clamp plate 601, which is slidably arranged at the bottom of the positioning plate 5, and a connecting plate 602 is fixedly arranged on the outer periphery of the clamp plate 601; two groups of limiting holes 501 are symmetrically opened at the bottom of the positioning plate 5, and the connecting plates 602 in the two groups of clamps 6 respectively pass through the two groups of limiting holes 501 upward to penetrate the positioning plate 5 and are respectively connected to the two groups of connecting components 9;

[0049] The connecting plate 602 includes an inverted L-shaped fixing plate 6021, the end of the vertical section of the fixing plate 6021 is provided with a limiting hole 501 and fixedly connected to the clamping plate 601, the end of the horizontal section of the fixing plate 6021 is provided with a sliding plate 6022 on the inner periphery of the sliding sleeve, the end of the sliding plate 6022 away from the fixing plate 6021 is fixedly connected to the end plate 6023, and the other end of the end plate 6023 is connected to the connecting assembly 9; a spring 6024 is provided in the fixing plate 6021, one end of the spring 6024 is connected to the sliding plate 6022, and the other end is connected to the fixing plate 6021;

[0050] When in use, after the dowel 201 is docked with the positioning plate 5, as the hoisted prefabricated wall 1 slowly moves downward, the bidirectional screw rod 8 rotates to drive the two sets of connection components 9 to approach each other, and the two sets of connection components 9 drive the two sets of clamping plates 601 to approach each other through the two sets of connection plates 602 until the clamping plates 601 are clamped on the outer periphery of the dowel 201;

[0051] In the process of clamping the dowel 201, the position of the prefabricated panel 2 is automatically adjusted by the thrust of the clamp 601 on the dowel 201. After the clamps 601 in the clamps 6 at both ends of the prefabricated wall 1 clamp the corresponding dowel 201 respectively, the axis of the corresponding dowel 201 will coincide with the axis of the side tube 101 at both ends of the prefabricated wall 1, and the middle tube 102 will also automatically coincide with the axis of the corresponding dowel 201, automatically completing the precise docking of the dowel 201 on the prefabricated panel 2 and the sleeve of the prefabricated wall 1; in addition, by setting the spring 6024, the elasticity of the spring 6024 can be utilized to make the movable plate 4 and the fixed plate 6021 elastically connected, that is, the fixed plate 6021 can be extended, thereby eliminating the interference caused by the inability of the gear 802 to rotate due to the size error of the dowel 201, thereby increasing the applicability of the clamping assembly.

[0052] Preferably, the connecting assembly 9 includes a slider 901, which is screwed with the external thread of the bidirectional screw rod 8, and a sleeve rod 902 is fixedly connected to one side of the slider 901, and a vertical connecting rod 903 is slidably sleeved on the end of the sleeve rod 902 away from the slider 901; two groups of bar holes 402 are opened on the movable plate 4, and the two groups of bar holes 402 are symmetrically arranged on both sides of the center hole 401 and connected to the center hole 401, and the connecting rods 903 in the two groups of connecting assemblies 9 are respectively penetrated by the two groups of bar holes 402 and penetrated upwardly by the movable plate 4, and the bottoms of the two groups of connecting rods 903 are respectively fixedly connected to the two groups of clamps 6;

[0053] When in use, after the dowel 201 is docked with the positioning plate 5, as the hoisted prefabricated wall 1 slowly moves downward, the dowel 201 pushes the positioning plate 5 upward, and the positioning plate 5 drives the connecting rod 903 through the clamp 6 to pass through the strip hole 402 upward to penetrate the movable plate 4 and into the fixed tube 3; at the same time, as the two-way screw 8 rotates, the two groups of sliders 901 are driven to approach each other, and the two groups of sliders 901 drive the two groups of connecting rods 903 to approach each other through the sleeve rod 902, thereby driving the two groups of clamps 6 to approach each other to clamp the dowel 201, thereby automatically adjusting the position of the prefabricated plate 2, so that the dowel 201 on the prefabricated plate 2 and the sleeve of the prefabricated wall 1 can be automatically and accurately docked.

[0054] Preferably, a torsion assembly is provided in the fixed cylinder 3 for driving the fixed cylinder 3 to rotate.

[0055] The torsion assembly includes a slide bar 1101, which is slidably arranged in the shaft 10. The slide bar 1101 only moves up and down in the shaft 10. The top of the slide bar 1101 is fixedly connected with a driving plate 11. The inner circumference of the upper half of the fixed cylinder 3 is provided with rifling 12. The driving plate 11 is provided with a protrusion that slidably cooperates with the rifling 12. When the driving plate 11 is not pushed by the shaft 10, the protrusion on it cooperates with the rifling 12, so that it is at the bottom of the rifling 12 and is mounted on the top of the shaft 10.

[0056] A limiting groove is provided in the shaft rod 10, and a protrusion that slides with the limiting groove is provided at the bottom of the slide rod 1101;

[0057] During use, after the clamp 6 clamps the dowel 201, as the hoisted prefabricated wall 1 continues to move downward, the shaft rod 10 moves upward until it abuts against the drive plate 11 and pushes the drive plate 11 to move vertically upward along the rifling 12. Because the clamp 6 has been clamped on the surface of the dowel 201, the shaft rod 10 will not rotate at this time, and the drive plate 11 will not rotate. Therefore, the protrusion on the drive plate 11 moves upward along the rifling 12 in the fixed tube 3, causing the fixed tube 3 to automatically deflect, thereby causing the external thread of the fixed tube 3 to move out from the thread of the internal threaded sleeve 103. At this time, the fixed tube 3 will automatically release the connection relationship with the internal threaded sleeve 103, thereby improving the overall efficiency of the docking.

[0058] Preferably, the outer circumference of the fixing tube 3 is also provided with anti-slip grooves, so that workers can install the fixing tube 3 in the side tube 101 easily.

[0059] Preferably, a sleeve block 1001 is provided on the top of the shaft rod 10 , and the diameter of the sleeve block 1001 is larger than the diameter of the center hole 401 ; the sleeve block 1001 is used to limit the shaft rod 10 and prevent the shaft rod 10 from escaping from the movable plate 4 .

[0060] A construction method for a prefabricated wall structure of an assembled house comprises the following steps:

[0061] S1. Construction preparation: Before construction, carefully check the quality of the prefabricated wall 1 and the prefabricated panel 2 to ensure that there is no damage or defect and confirm that the sleeve of the prefabricated wall 1 and the dowel 201 on the prefabricated panel 2 match in size;

[0062] S2. Install the positioning pieces: Screw the fixing tubes 3 of the two sets of positioning pieces into the side tubes 101 at both ends of the prefabricated wall 1 according to the design requirements, and ensure that the positioning pieces are correctly installed and can rotate;

[0063] S3, hoisting the prefabricated wall 1: use the hoisting equipment to steadily hoist the prefabricated wall 1 and position it above the prefabricated board 2; during this process, the staff manually assists in adjusting the position to ensure that the positioning plates 5 at both ends of the prefabricated wall 1 can accurately dock with the corresponding dowel bars 201 on the prefabricated board 2;

[0064] S4, automatic positioning: when the prefabricated wall 1 is placed in place, the dowel 201 is gently in contact with the positioning plate 5. As the prefabricated wall 1 slowly descends, the dowel 201 will push the positioning plate 5 upward, triggering the clamp 6 to automatically clamp the dowel 201. The pressure applied by the clamp 6 to the dowel 201 automatically fine-tunes the position of the prefabricated board 2, so that the positioning plates 5 at both ends of the prefabricated wall 1 are completely aligned with the corresponding dowel 201 axis, thereby achieving automatic and precise positioning between the prefabricated wall 1 and the prefabricated board 2;

[0065] S5, removing the positioning piece: after the prefabricated wall 1 and the prefabricated panel 2 are automatically positioned, the fixing tube 3 is rotated to disengage it from the internal threaded sleeve 103, allowing the entire positioning piece to rise together with the prefabricated wall 1 and enter the side tube 101;

[0066] S6. Fixing and grouting: After confirming that the prefabricated wall 1 is firmly seated on the prefabricated panel 2, inject concrete or other designated grouting materials into the sleeve through the grouting holes reserved on the top of the prefabricated wall 1 to fill the gap between the prefabricated wall 1 and the prefabricated panel 2 to enhance the connection strength between the two. After the grouting is completed, according to the requirements of the grouting material used, give it appropriate time to solidify to complete the installation of the prefabricated wall 1 structure.
