Technical Field

[0001] The present application relates to the technical field of installation of external wall panels, and in particular to an installation auxiliary device and an installation method of an external wall panel. Background Art

[0002] At present, with the continuous development and progress of building industrialization, more and more engineering designs have adopted precast concrete exterior wall panel technology that is prefabricated in component factories and installed on site.

[0003] A Chinese patent document with application number CN202010512515.5 in the related art discloses a connection node of a point-supported precast concrete external wall panel, including an external wall panel and a main structure, wherein the external wall panel includes an upper connection node and a lower connection node, and a rotating support is fixedly connected to the main structure; the rotating support includes a rotating member and a limiter fixedly connected to the main structure; one end of the rotating member is located in the limiter and abuts against the main structure, and the other end extends upward out of the limiter and is fixedly connected to the upper connection node of the external wall panel; the limiter is provided with a through hole for the rotating member to pass through and a space for the rotating member to move up and down, and the through hole and the rotating member are connected. There is a gap between them; the rotating member includes a rotating part, and the rotating part includes a spherical part located at the bottom and a circular plane arranged at the center of the spherical part for abutting against the main structure; the upper connecting node is provided with a connecting part for connecting with the lower connecting node of the upper external wall panel, and the connecting part is provided with a margin for the lower connecting node to move up, down, left and right; the limiter includes a top plate and a plurality of side plates connected to the top plate, and the side plates are welded and fixed to the main structure; the through hole is arranged at the center of the top plate; a second embedded part is provided on the main structure, and the second embedded part includes a connecting steel plate located on the surface of the main structure and embedded steel bars located in the main structure and welded to the connecting steel plate.

[0004] Regarding the above-mentioned related technologies, since the installation process of external wall panels is a high-altitude operation, when they are installed on site, they are mostly hoisted by equipment such as tower cranes or truck cranes. The external wall panels will swing during the hoisting process, making it difficult for the limiters on the connection nodes to be aligned and positioned with the welding positions on the main structure, affecting the hoisting efficiency. Summary of the invention

[0005] In order to improve the hoisting efficiency of external wall panels, the present application provides an installation auxiliary device and an installation method for external wall panels.

[0006] In a first aspect, the present application provides an auxiliary device for installing an external wall panel, which adopts the following technical solution:

[0007] An auxiliary installation device for external wall panels includes a frame for leaning against a main structure, the frame includes an opening for a limiter of a connection node to enter, a positioning assembly is arranged in the opening of the frame, the positioning assembly includes a vertical limit plate and horizontal guide plates arranged on both sides of the vertical limit plate, a positioning groove for aligning the limiter is formed between the two horizontal guide plates and the vertical limit plate, and the positioning groove is a flared structure.

[0008] By adopting the above technical solution, when the wall panel is hoisted close to the main structure, the limiter on the wall panel can enter the opening of the frame, and the two horizontal guide plates can provide spatial guidance for the limiter, so that the limiter can enter the positioning groove through the two horizontal guide plates and counteract the vertical limiter, thereby achieving rapid alignment of the limiter and improving the installation efficiency of the external wall panel.

[0009] Optionally, the open end of the frame is provided with a buffer member for abutting against the outer side of the main structure.

[0010] By adopting the above technical solution, when the wall panel is hoisted close to the main structure, the wall panel will contact the buffer component, thereby reducing the impact force of the wall panel on the main structure.

[0011] Optionally, the buffer member is a buffer pad symmetrically arranged at the ends of both sides of the frame opening.

[0012] By adopting the above technical solution, the buffer pads are symmetrically arranged on both sides of the frame opening, which can balance the impact on both sides of the wall panel, thereby improving the buffering effect of the buffer pads on the wall panel. At the same time, after the connection nodes of the wall panel and the main structure are initially spot welded, the buffer pads can be pulled out from the main structure together with the frame, thereby realizing the reusability of the frame.

[0013] Optionally, the frame includes a rod arranged at the outer bottom of the two guide plates and used to lean on the main structure, the rod includes a horizontal part for leaning on the main structure and a vertical part arranged perpendicular to the front end of the horizontal part, and the buffer pad is arranged around the outer peripheral side of the vertical part.

[0014] By adopting the above technical solution and setting the levers, the structural strength of the two guide plates can be effectively improved.

[0015] Optionally, the buffer pad has a cylindrical structure.

[0016] By adopting the above technical solution, the cushion pad with a cylindrical structure is provided, so that the cushion pad can produce a larger range of deformation, improve the cushioning effect, and the thickness of the cushion pad can be adjusted according to the gap width between the wall panel and the main structure. At the same time, the cushion pad is provided with a cylindrical structure, which can reduce the contact area between the cushion pad and the main structure and the wall panel, thereby reducing the friction resistance when the cushion pad is pulled out.

[0017] Optionally, the vertical limiting plate and the horizontal guide plate are both arranged to be inclined toward a space away from the positioning groove.

[0018] By adopting the above technical solution, the limiter of the connection node can be guided in the vertical direction through the inclined horizontal guide plate and the vertical limit plate.

[0019] Optionally, the frame further includes a connecting rod disposed on a side of the vertical limiting plate away from the positioning groove, and both ends of the connecting rod are respectively fixedly connected to a frame rod.

[0020] By adopting the above technical solution and setting the connecting rods, the overall structural strength of the scaffolding can be improved.

[0021] Optionally, the connecting rod and the two supporting rods are an integrally formed structure.

[0022] By adopting the above technical solution, since the connecting rod and the two supporting rods are an integrally formed structure, the force bearing performance between the connecting rod and the two supporting rods can be improved, and processing is convenient.

[0023] In a second aspect, the present application provides a method for installing an auxiliary device for installing an external wall panel, which adopts the following technical solution:

[0024] A method for installing an auxiliary device for installing an external wall panel comprises the following steps:

[0025] Step 1: Draw the positioning line of the stopper installation position on the embedded steel plate of the main structure;

[0026] Step 2: Install the frame on the embedded steel plate;

[0027] Step 3: After the stopper is aligned in the positioning groove, pre-fix the stopper by spot welding, then take out the frame and complete the welding of the remaining part of the stopper.

[0028] Optionally, in step 2, two horizontally inclined positioning steel bars are pre-welded on the embedded steel plate of the main structure, and the scaffolding is installed between the two positioning steel bars for positioning.

[0029] By adopting the above technical solution and setting the positioning steel bars, the scaffolding can be limited so that the scaffolding is not easily moved.

[0030] In summary, the present application includes at least one of the following beneficial effects:

[0031] 1. The present application can guide the supports of the connection nodes in the horizontal and vertical space by setting the inclined vertical limit plates and horizontal guide plates, thereby improving the installation efficiency of the external wall panels;

[0032] 2. By setting up the scaffolding and buffer pads, the impact force on the main structure during the installation of the wall panels can be effectively reduced; at the same time, the installation auxiliary devices can be reused.

[0033] 3. The construction speed is fast. After testing, the applicant found that each tower crane in the laboratory could lift 4 blocks a day, and each tower crane could lift 8 blocks a day in the early stage of the site. In the later stage, each tower crane could lift 12-14 blocks a day, which implemented the goals of rapid installation, low-carbon environmental protection, energy conservation and emission reduction at the construction site of industrialized buildings.

DETAILED DESCRIPTION

[0039] The present application is further described in detail below in conjunction with the accompanying drawings.

[0040] The present application embodiment discloses an auxiliary device for installing an external wall panel. Figure 1 , 2 The auxiliary installation device includes a frame 3, and a buffer is provided at one end of the frame 3. The frame 3 can be placed on the upper end surface of the main structure 2, and the buffer can be placed on the outer wall of the main structure 2, so that when the wall panel 1 is hoisted to the main structure 2, the wall panel 1 can contact the buffer first, reducing the impact force of the wall panel 1, thereby effectively preventing the wall panel 1 from colliding with the main structure 2.

[0041] Reference Figure 1 , 2The frame 3 includes an opening for the limiter of the connection node to enter, and a positioning assembly is arranged in the opening. The buffer is a buffer pad 4 symmetrically arranged at the end of the opening, and the buffer pad 4 can be a buffer material such as rubber. When the wall panel 1 is against the buffer pad 4, the limiter in the shape of a trapezoidal box on the wall panel 1 can enter the frame 3 through the opening, and be guided to the desired position by the positioning assembly, so as to realize the rapid alignment of the connection node of the wall panel 1. At the same time, after the limiter of the connection node is partially welded and fixed to the main structure 2, the frame 3 and the buffer pad 4 can be pulled out from the main structure 2 together, and then the remaining part between the limiter and the main structure 2 can be welded, so as to realize the reusability of the installation auxiliary device.

[0042] Reference Figure 2 , 3 The positioning assembly includes a vertical limit plate 5 and horizontal guide plates 6 welded to both ends of the vertical limit plate 5. A positioning groove 7 for aligning the limiter on the connection node is formed between the vertical limit plate 5 and the two horizontal guide plates 6. The positioning groove 7 is an overall flared structure, which is used to facilitate the limiter on the connection node to enter the positioning groove 7 in the horizontal direction for alignment.

[0043] Further, see Figure 2 , 3 , the horizontal guide plate 6 and the vertical limit plate 5 are both inclined outwardly in the direction away from the positioning groove 7. The inclined horizontal guide plate 6 and the vertical limit plate 5 can provide a vertical space guide for the limiter of the connection node. At the same time, the operator can better weld the limiter of the connection node with the help of the space formed by the inclined horizontal guide plate 6 and the vertical limit plate 5.

[0044] Reference Figure 2 , 3 The frame 3 includes a spanning rod 9 welded to the bottom of the two horizontal guide plates 6 on the side away from the positioning groove 7, which is used to increase the structural strength of the horizontal guide plates 6. The frame 3 also includes a connecting rod 8 welded to the side of the vertical limit plate 5 away from the positioning groove 7, and each end of the connecting rod 8 is connected to a spanning rod 9. The two spanning rods 9 and the connecting rod 8 are an integrally formed structure, and the connecting rod 8 and the two spanning rods 9 can be bent from a steel bar, thereby improving the overall force bearing performance of the connecting rod 8 and the spanning rod 9.

[0045] Further, see Figure 2 , 3The spanning rod 9 includes a horizontal portion 912 extending in the horizontal direction and a vertical portion 911 extending in the vertical direction, and the connection between the horizontal portion 912 and the vertical portion 911 of the spanning rod 9 is an arc transition. The horizontal portion 912 of the spanning rod 9 can be pressed against the upper end surface of the main structure 2 together with the horizontal guide plate 6, and the vertical portion 911 of the spanning rod 9 can be buckled vertically downward on the outside of the main structure 2. In other embodiments, the frame 3 can also be a support plate arranged on the outer peripheral side of the horizontal guide plate 6, and the outer end of the support plate is provided with a vertically arranged downwardly extending plate for leaning against the outside of the main structure 2, and the buffer pad 4 is distributed on the outside of the plate.

[0046] Reference Figure 3 , 4 The buffer pad 4 is arranged around the outer circumference of the vertical portion 911, and the buffer pad 4 is a cylindrical structure coaxial with the vertical portion 911, so that the buffer pad 4 is in line contact with the outer side of the main structure 2 and the inner side of the wall panel 1, which increases the deformability of the buffer pad 4. At the same time, it is convenient to pull the frame 3 upward later, reducing the friction resistance between the buffer pad 4 and the main structure 2 and the wall panel 1. The thickness of the buffer pad 4 can be adjusted according to the seam width between the wall panel 1 and the main structure 2.

[0047] The implementation principle of the auxiliary device for installing an external wall panel in the embodiment of the present application is as follows:

[0048] When installing the scaffolding 3, first draw the positioning line of the position of the limiter of the connection node on the embedded steel plate of the main structure 2, and then pre-weld two horizontally inclined positioning steel bars 10 on the embedded steel plate of the main structure 2 according to the hoisting situation, install the scaffolding 3 at the specified position, and abut against the two positioning steel bars 10, so that the scaffolding 3 is not easy to deviate; then hoist the wall panel 1 to contact with the buffer pad 4, so that the limiter of the connection node enters the positioning groove 7 and aligns, and then spot welds the limiter of the connection node, so that the limiter of the connection node is pre-fixed on the embedded steel plate of the main structure 2, and finally take out the scaffolding 3 and weld the remaining part to complete the installation of the external wall panel 1. At the same time, the scaffolding 3 can be reused.

[0049] The embodiment of the present application also discloses a method for installing an auxiliary device for installing an external wall panel, which includes the following steps:

[0050] Step 1: Draw a positioning line for the installation position of the stopper on the embedded steel plate of the main structure 2;

[0051] Step 2: Place the scaffolding 3 on the embedded steel plate; according to the actual lifting situation, two horizontally inclined positioning steel bars 10 may be pre-welded on the embedded steel plate of the main structure 2, and the scaffolding 3 may be installed between the two positioning steel bars 10 for positioning;

[0052] Step 3: After the stopper is aligned in the positioning groove 7, the stopper is pre-fixed and spot welded, and then the frame 3 is removed from the embedded steel plate in the vertical direction, and the remaining part of the stopper is welded.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
