Description

Technical Field

[0001] The invention belongs to the technical field of wall panel installation, and in particular relates to a prefabricated clear water wall panel installation method and installation structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories (such as floor slabs, wall panels, stairs, balconies) are processed and manufactured in the factory, transported to the construction site, and assembled and installed on site through reliable connection methods.

[0003] Prefabricated buildings mainly include prefabricated concrete structures, steel structures, and modern wooden structures. They are representatives of modern industrialized production methods because they adopt standardized design, factory production, assembly construction, information management, and intelligent applications.

[0004] Prefabricated buildings are developing day by day, and various buildings with complex shapes and lines are constantly appearing. Among them, there are structures with prefabricated exterior wall panels hanging on three sides of the cantilevered main structure beam. There are no working surfaces on the three sides of this kind of cantilevered main structure beam, so construction operations cannot be carried out, and operation racks cannot be set up on the outside, otherwise it will affect the installation of prefabricated wall panels.

[0005] The shortcomings of the existing wall panel assembly construction are that due to the heavy weight of the assembled wall panels, the high installation precision required for the finishing, and the lack of a working surface at high altitude, the conventional installation method cannot be used to install such three-sided exterior wall panels. How to quickly and high-quality complete the construction of prefabricated plain wall panels under such working conditions has become a major problem. Summary of the invention

[0006] The purpose of the present invention is to provide a prefabricated clear water wall panel installation method and installation structure in view of the problems existing in the prior art.

The connectors C are used to connect the U-shaped metal parts A on the prefabricated clear water wall panels; S3: Wall panel installation: Install the prefabricated clear water wall panels on one side first, and then install the restricted side; the installation steps of a single prefabricated clear water wall panel are as follows: S31: hoist the prefabricated clear water wall panel to the installation position, lower the prefabricated clear water wall panel, and temporarily blindly install the lower opening groove of the U-shaped metal part A on the prefabricated clear water wall panel and the support shaft pin of the connecting part C into contact with each other. At this time, the support node screw rod C4 must not be in a stressed state; S32: Wallboard adjustment: After the prefabricated clear water wallboard is temporarily in place, the wallboard elevation is tested and then the prefabricated clear water wallboard is raised; by setting a number of U-shaped gaskets on the upper load-bearing support D, the installation height of the upper metal part B on the prefabricated clear water wallboard is adjusted to correspond to the elevation; the prefabricated clear water wallboard is dropped onto the U-shaped gaskets again to complete the wallboard elevation adjustment; and then the position of the prefabricated clear water wallboard in other directions is adjusted; S33: Wall panel fixing: a fixed cover plate is arranged on the metal column of the upper load-bearing support D, and the fixed cover plate is fixed to the upper metal part B by welding.

In S3, when installing the wall panel, it is installed from bottom to top, first one side and then the other side. Specifically, in S31, the prefabricated clear water wall panel is first hoisted to the installation position area, so that the lower opening groove of the U-shaped metal piece A is located directly above the support shaft pin of the connector C, and then the prefabricated clear water wall panel is lowered so that the support shaft pin is located in the lower opening groove and is temporarily in contact with the top of the lower opening groove without being affected by Pressure; in S32, when temporarily in place, after verifying the elevation of the wall panel, the prefabricated clear water wall panel is raised to install the U-shaped gasket, so that when the prefabricated clear water wall panel is installed at the elevation position, the connecting member C is connected to the U-shaped metal member A, and the upper metal member B is connected to the U-shaped gasket on the upper load-bearing support D, so as to realize the positioning of the upper and lower sides of the prefabricated clear water wall panel, and realize the adjustment of the height direction of the prefabricated clear water wall panel, and then the position of the wall panel in other directions can be adjusted to ensure the installation accuracy. After the position adjustment of the wall panel is completed in S33, a fixed cover plate is set on the metal column, and the upper metal member B is connected and fixed to the upper load-bearing support D through the fixed cover plate to realize the fixation of the wall panel.

[0013] A U-shaped groove is set to facilitate the position adjustment between the upper metal part B and the upper load-bearing support D. After completing the elevation, the sealing plate is welded to connect the upper metal part B with the upper load-bearing support D to bear the force of the prefabricated plain wall panel. The side part of the U-shaped metal part A of the wall panel is adjusted by a separate jack to achieve precise positioning of the plane position of the wall panel.

[0014] Furthermore, the distance between the outermost end of the wall panel and the horizontal control line is measured by a steel tape measure to verify the plane position deviation of the wall panel. The operation is simple.

[0015] Furthermore, in step S32, a steel tape measure is used to measure the distance from the outer surface of the prefabricated plain wall panel to the horizontal control line, the verticality deviation of the wall panel is verified, and a tensioner is used to connect the back steel frame of the prefabricated plain wall panel and the upper load-bearing support D metal column to complete the verticality adjustment of the wall panel.

[0016] The verticality deviation of the wall panel is checked by testing the distance between the outer surface of the wall panel and the horizontal control line, and the tensioner is set to adjust the verticality of the wall panel.

[0017] Furthermore, in step S31, when the prefabricated plain wall panels are hoisted to the vicinity of the installation position, the construction workers stand on the upper part of the beam and set a positioning rope on the upper part of the prefabricated plain wall panels to pull the wall panels to a state parallel to the beam and stationary, and higher than the set height of the installation position, and then lower the wall panels for temporary positioning.

[0018] The position of the wall panel is adjusted manually using the positioning rope so that the wall panel is in a static state, and the lower opening groove of the U-shaped metal part A is located directly above the supporting shaft pin of the connecting part C to facilitate temporary blind installation.

Example

[0032] like Figure 1-7 As shown, a method for installing a prefabricated clear water wall panel comprises the following steps: S1: Prefabricated production of wall panels. Prefabricated plain wall panels are prefabricated and produced in a prefabrication factory. Two U-shaped metal parts A5 are welded to the lower part of the wall panel, and two L-shaped upper metal parts B6 are welded to the upper part of the wall panel. The L-shaped upper metal part B6 has a notch 12 for on-site installation and fastening of the upper load-bearing support D4.

[0033] S2: The crossbeam 7 connector is installed. Two connectors C and two upper load-bearing supports D4 are welded and installed on the top of the H-shaped steel beam. The upper load-bearing support D4 is used to connect the embedded parts B on the top of the prefabricated clear water wall panel. The connector C is used to connect the U-shaped metal parts A5 on the top of the prefabricated clear water wall panel.

[0034] The connector is installed according to the drawing positioning. The center control line 10 and the elevation control line are drawn from the measurement baseline network using a total station and theodolite, and the installation position of the connector is checked and corrected; the connector C of the lower H-shaped steel beam and the upper load-bearing support D4 are installed. The connector C is welded by a steel rectangular tube 301, a U-shaped channel steel 302, and a stiffening plate 305. A screw is set to pass through the slotted hole 303 on the U-shaped channel steel 302, and the screw is tightened with a nut. The upper load-bearing support D4 is welded by a cylindrical iron rod, i.e., a metal column 402, and an iron plate 401 to form a T-shaped connector.

[0035] S3: Wall panel installation: Install the prefabricated clear water wall panels on one side first, then the prefabricated clear water wall panels on the restricted side. The installation steps for a single prefabricated clear water wall panel are as follows: S31: When the prefabricated exposed concrete wall panel is hoisted to 1m away from the installation position, the construction workers stand on the upper part of the H-shaped steel beam and set the positioning rope on the upper part of the prefabricated exposed concrete wall panel to pull the wall panel to a state parallel to the H-shaped steel beam and 0.5m above the installation position. By slowly rotating the tower crane boom, the prefabricated exposed concrete wall panel is translated to the top of the installation position. By slowly lowering the hook, the prefabricated exposed concrete wall panel embedded U-shaped metal part A5 is temporarily blindly installed and contacted with the support node screw rod. At this time, the support node screw rod must not be under stress.

[0036] S32: Wallboard adjustment: After the prefabricated plain wallboard is temporarily in place, the wallboard elevation is tested with a laser level. The prefabricated plain wallboard is adjusted to a position 1-2 mm above the installation elevation through the hand chain hoist fall chain at the upper two hanging points, and left to stand. By adding or reducing U-shaped gaskets 8 of different thicknesses on the upper load-bearing support B, its elevation is adjusted to the precise installation position. The wallboard is slowly lowered to the upper load-bearing support through the hand chain hoist fall chain at the upper two hanging points again to complete the wallboard elevation adjustment.

[0037] The prefabricated plain wall panel is now in a support stress state by welding a square iron plate 401 as a sealing plate 11 outside the U-shaped notch 12 of the L-shaped upper metal part B6 embedded part. The distance between the outermost end of the wall panel and the horizontal control line is measured by a steel tape measure to verify the plane position deviation of the wall panel. A separate jack is placed between the upper load-bearing support D4 metal column 402 and the side of the embedded U-shaped metal part B to adjust the left and right plane positions of the wall panel. During the process, the deviation is re-measured in real time until the designed plane position is reached.

[0038] Use a steel tape measure to measure the distance from the outer surface of the prefabricated exposed concrete wall panel to the horizontal control line, and check the verticality deviation of the wall panel. Use a tensioner to connect the prefabricated exposed concrete wall panel back steel frame 2 and the upper load-bearing support D4 metal column 402 to complete the verticality adjustment of the wall panel.

[0039] S33: Wallboard fixing: Place the fixing cover plate 13 on the upper load-bearing support D4 metal column 402, and weld the fixing cover plate 13 to the upper metal part B6 by gas shielded welding. According to the above process requirements, the installation of the prefabricated clear water wallboard on the other side is completed.

[0040] All connectors and connecting plates are treated with anti-corrosion and anti-rust. The connectors on the beam 7 and the wall panels are preferably made of Q345B steel, and the plate thickness and size should meet the design calculation requirements.

[0041] During the external installation construction of prefabricated facing plain concrete wall panels, when there is no working surface, construction operations cannot be carried out, and an operating frame cannot be set up on the outside, this method uses technical means such as blind installation nodes with upper load-bearing supports and lower reverse support slot point connections and three-dimensional high-precision adjustment methods to solve the problem of high-precision installation construction of prefabricated plain concrete wall panels in high-altitude confined spaces, ensuring the effect of facing plain concrete.

[0042] In the above scheme, installation preparation work is carried out in S1 and S2, an upper metal piece B6 is set on the upper part of the prefabricated clear water wall panel to cooperate with the upper load-bearing support D4 on the beam 7, and a U-shaped metal piece A5 is set on the lower part to cooperate with the installation connector C3, so as to realize the connection of the prefabricated clear water wall panel to the beam 7.

Specifically, in S31, the prefabricated clear water wall panel is first hoisted to the installation position area, so that the lower opening groove 9 of the U-shaped metal piece A5 is located directly above the support shaft pin of the connector C, and then the prefabricated clear water wall panel is lowered so that the support shaft pin is located in the lower opening groove 9 and is temporarily in contact with the top of the lower opening groove 9 without being subjected to pressure. ; In S32, when the prefabricated clear water wall panel is temporarily in place, after checking the elevation of the wall panel, the prefabricated clear water wall panel is raised to install the U-shaped gasket 8, so that when the prefabricated clear water wall panel is installed at the elevation position, the connecting member C is connected to the U-shaped metal member A5, and the upper metal member B6 is connected to the U-shaped gasket 8 on the upper load-bearing support D4, so as to realize the positioning of the upper and lower sides of the prefabricated clear water wall panel, and realize the adjustment of the height direction of the prefabricated clear water wall panel, and then the position of the wall panel in other directions can be adjusted to ensure the installation accuracy. After the position adjustment of the wall panel is completed in S33, a fixed cover plate 13 is set on the metal column 402, and the upper metal member B6 is connected and fixed to the upper load-bearing support D4 through the fixed cover plate 13 to realize the fixing of the wall panel.

After the elevation is completed, the sealing plate 11 is welded to connect the upper metal part B6 with the upper load-bearing support D4 to bear the force of the prefabricated plain wall panel. The side part of the U-shaped metal part A5 of the wall panel is adjusted by a separate jack to achieve precise positioning of the plane position of the wall panel.

[0048] Furthermore, the distance between the outermost end of the wall panel and the horizontal control line is measured by a steel tape measure to verify the plane position deviation of the wall panel. The operation is simple.

[0049] Furthermore, in step S32, a steel tape measure is used to measure the distance from the outer surface of the prefabricated plain wall panel to the horizontal control line, the verticality deviation of the wall panel is verified, and a tensioner is used to connect the back steel frame 2 of the prefabricated plain wall panel and the upper load-bearing support D4 metal column 402 to complete the verticality adjustment of the wall panel.

[0051] Furthermore, in step S31, when the prefabricated plain wall panels are hoisted to the vicinity of the installation position, the construction workers stand on the upper part of the beam 7, and by setting a positioning rope on the upper part of the prefabricated plain wall panels, the wall panels are pulled to a state parallel to the beam 7 and stationary, and higher than the set height of the installation position, and then the wall panels are lowered for temporary positioning.
