[0028] The present invention also provides a method for installing a building concrete pre-support assembly, comprising the following steps: S1. Clean the construction site, measure and mark the installation position of the hollow column 1 and the placement point of the U-shaped bottom plate 41, prepare the installation tools, and place the U-shaped bottom plate 41; S2. Use a verticality measuring instrument to measure the verticality of the side guide plate 48. When tilting, push the U-shaped pull rod 44 to adjust until it is vertical. Turn the threaded rod 46 to fix the position. Lift the hollow column 1 and insert it using the cross section of the side guide plate 48 as a guide. S3, lift the prefabricated wall panel 2, align it with the dovetail groove 32, insert the dovetail plate 35, and insert the positioning block 34 into the positioning square groove 33 to fix the position so that the upper surfaces of the two are flush; S4. Start the dual-axis motor 510, adjust the side support plate 54 to fit the hollow column 1, insert the U-shaped top plate 51, and use the auxiliary plug plate 52 to block the bottom end of the limit plate 31; S5. Pour concrete into hollow column 1 and vibrate, then maintain according to specifications to ensure strength; S6. After the concrete reaches the specified strength, the dual-axis motor 510 is started in reverse to dismantle the support assembly, and then the U-shaped top plate 51 and the end top plate 53 are dismantled, and the U-shaped bottom plate 41 is pulled out.

[0029] The present invention provides a building concrete pre-support assembly through improvement, and its working principle is as follows: First, clean the construction site and ensure that the installation area is free of debris and obstacles. According to the architectural design drawings, accurately measure and mark the installation position of the hollow column 1, determine the placement point of the U-shaped base plate 41, ensure that the measurement error is within the allowable range, and prepare installation tools such as verticality measuring instruments, wrenches, and pins, and place the U-shaped base plate 41 in the marked position; Second, use a verticality measuring instrument such as a theodolite or a plumb bob to measure the verticality of the side guide plates 48. If the side guide plates 48 are tilted, push the U-shaped pull rod 44 to make it slide in the U-shaped positioning plate 45. Due to the support of the support plate 42 and the rotation of the lower U-shaped block 43, the two side guide plates 48 will rotate synchronously. During the adjustment process, observe the verticality measuring instrument until the side guide plates 48 are adjusted to a vertical state. At the same time, the first T-shaped slide plate 411 will slide in the first T-shaped slide groove 49 to ensure that the bottom end of the side guide plates 48 is in contact with the mounting surface of the hollow column 1 to prevent mortar leakage during pouring. After the side guide plates 48 are adjusted to a vertical state, the handwheel on the threaded rod 46 can be turned so that the bottom of the threaded rod 46 is against the U-shaped pull rod 44 to fix the position of the adjusted side guide plates 48. Use a crane to lift the hollow column 1 above the U-shaped bottom plate 41 and slowly lower it. Use the inclined section 1 on the top of the two side guide plates 48 and the inclined section 2 on the upper surface of the main guide plate 47 to guide the hollow column 1 to be accurately inserted between the two side guide plates 48. The position of the hollow column 1 can be supported by the steel bars at the bottom of the hollow column 1. Third, use a crane to lift the prefabricated wall panel 2 to a suitable position near the hollow column 1. Adjust the direction of the prefabricated wall panel 2 so that its dovetail plate 35 is aligned with the dovetail groove 32 of the upper limit plate 31 of the hollow column 1. Insert the dovetail plate 35 into the dovetail groove 32. When the positioning block 34 is inserted into the positioning square groove 33, the relative position of the prefabricated wall panel 2 and the hollow column 1 is fixed, and the upper surface of the prefabricated wall panel 2 is flush with the upper surface of the hollow column 1. The splicing and installation of the prefabricated wall panel 2 and the hollow column 1 are completed. Fourth, connect the dual-axis motor 510 with the external power supply, start the dual-axis motor 510 through the controller, and the dual-axis motor 510 drives the two screw rods 511 to rotate synchronously. The rotation of the screw rod 511 causes the concave plate 512 to move in the direction close to the dual-axis motor 510, and the side support plate 54 is pushed toward the direction close to the hollow column 1 through the tilting rod 59. Observe the fit between the side support plates 54 and the hollow column 1 until the two side support plates 54 are tightly fitted with the surface of the hollow column 1. Since the longitudinal U-shaped block 58 can rotate in the second T-shaped slide plate 56, the second T-shaped slide plate 56 can slide in the side support plate 54, and the longitudinal U-shaped block 58 is close to the top of the second T-shaped slide plate 56, the second T-shaped slide plate 56 is close to the upper surface of the side support plate 54, which can ensure that the side support plate 54 is parallel to and fits the surface of the hollow column 1, preventing ash leakage during pouring, and at the same time ensuring that one side of the formed concrete is in the same plane as the side of the hollow column 1; After the two side support plates 54 are attached to the surface of the hollow column 1, the U-shaped top plate 51 is inserted into the side slots 516 on the adjacent sides of the two side support plates 54, so that the U-shaped top plate 51 is sleeved on the surface of the prefabricated wall panel 2, and the end top plate 53 fixed on the bottom surface of the U-shaped top plate 51 cooperates with the hollow column 1 and the prefabricated wall panel 2. Under the joint action of the U-shaped top plate 51, the end top plate 53, the side support plates 54, the side guide plates 48, the main guide plates 47, the hollow column 1 and the prefabricated wall panel 2, a space is formed. The auxiliary plug-in plate 52 inside the U-shaped top plate 51 blocks the bottom end of the limit plate 31 on the other side of the prefabricated wall panel 2 to ensure that the upper surface of the prefabricated wall panel 2 is always flush with the hollow column 1 after subsequent splicing.

[0030] Fifth, concrete that meets the design requirements is poured into the space formed inside the hollow column 1. During the pouring process, the concrete is vibrated with a vibrator to ensure uniform filling of the concrete, avoid defects such as voids and honeycombs, and ensure a firm bond between the hollow column 1, the prefabricated wall panel 2, and the poured concrete. After the concrete is poured, it is cured in accordance with concrete curing specifications. Generally, methods such as covering with plastic film and sprinkling water for moisture retention are used to allow the concrete to harden under suitable temperature and humidity conditions. The curing time is determined according to the type of concrete and design requirements, and is usually not less than the specified number of days to ensure that the concrete reaches the design strength. Sixth, after the concrete reaches the specified strength, the components are dismantled. The dual-axis motor 510 is started in reverse to reverse the screw rod 511, driving the concave plate 512 away from the dual-axis motor 510. The side support plate 54 is pulled away from the hollow column 1 through the tilting rod 59, and the U-shaped top plate 51 and the end top plate 53 are removed. Then, the U-shaped bottom plate 41 is pulled out so that the U-shaped bottom plate 41 slides out from the surface of the poured concrete.
