Description

Technical Field

[0001] This solution relates to the field of construction, and specifically relates to a connection method between a non-masonry exterior wall panel and a main structure. Background Art

[0002] In the field of construction engineering, the method of installing wall panels for non-masonry exterior walls has gradually been applied. However, there are still many deficiencies in the connection structures of such exterior wall panels at present. In the existing connection methods for non-masonry exterior wall panels, the hook is often set on the inner side. For example, in the special hook bolt for installing ALC wall panels disclosed in the patent CN210857834U, the hook at one end of the screw rod contacts the edge of the wall panel, and a nut and washer are used to tighten and fix it on the other side of the wall. Although this structure realizes the rapid fixation of the wall panel through screw thread transmission and solves the problem of installation convenience, it essentially still continues the design logic of the connection of interior wall panels, and exposes the following defects in the application of non-masonry exterior walls: when the hook is on the inner side, after processes such as plastering are completed, the hook cannot be effectively covered, resulting in obvious defects on the inner side of the building. Taking the patent CN210857834U as an example, the hook and the screw rod are arranged at a right angle. During installation, the hook is located on the inner side of the wall panel, and after the screw rod passes through the wall, it is tightened with a nut on the outer side. At this time, the edge area of the hook on the inner side of the wall panel is difficult to cover by conventional plastering technology, forcing additional ceiling or edge wrapping treatment during construction, increasing the construction process and cost. Summary of the Invention

[0003] The present invention aims to provide a connection method between a non-masonry exterior wall panel and a main structure. By improving the connection structure of the non-masonry exterior wall, it is possible to avoid covering the hook after the installation of the non-masonry exterior wall, so as to reduce the construction process and cost.

[0004] To achieve the above object, the present invention adopts the following technical solution: The beneficial effect of this solution is as follows: A connection method between a non-masonry exterior wall panel and a main structure, which is used for the installation of ALC exterior wall panels, includes the following steps: Step 1: Set up the connection structure. The connection structure includes a limit angle steel and a number of expansion bolts. After the main structure is poured and meets the conditions for installing the exterior wall protection system, the limit angle steel is fixed on the structural beam through the expansion bolts to form the connection structure of the wall panel. At the same time, the limit angle steel is used to position the exterior wall panel and prevent the exterior wall panel from tilting outwards; Step 2: Install the wall panel. Lift and install the ALC exterior wall panel. After adjusting the verticality and flatness of the ALC exterior wall panel, the connection structure further includes a hook bolt. The wall panel is fixed on the limit angle steel through the hook bolt, and the hook is located on the outer side of the wall panel.

[0005] Beneficial effects: By setting the hook head of the hook bolt on the outer side of the wall panel and lapping it on the angle steel fixed on the structural beam, the hook head of the hook bolt is located on the visible side of the exterior wall, avoiding the problem of difficult plaster covering caused by the hook head being hidden inside the wall panel in the traditional structure. Thus, it effectively solves the defects caused by improper hook head position in the application of the existing connection structure in non-masonry exterior walls, eliminating the need for additional masking processes such as suspended ceilings or edge wrapping, simplifying the construction process, and reducing construction costs and construction periods.

[0006] In addition, the hook bolt and the angle steel are lap-connected and fixedly connected. This method is not only convenient for installation and reliable in connection, but also facilitates later inspection and maintenance, enhancing the overall applicability and engineering adaptability of the exterior enclosure connection structure, and is particularly suitable for non-masonry exterior wall systems in prefabricated buildings.

[0007] Furthermore, in step two, during fixation, first lap the hook head of the hook bolt on the angle steel and weld it to the angle steel. Subsequently, open a connection hole on the indoor side of the ALC exterior wall panel, and the connection hole is adapted to the bolt body of the hook bolt. Then, pass the bolt body through the connection hole and fixedly connect the ALC exterior wall panel and the limit angle steel through the bolt body.

[0008] Furthermore, it also includes step three: setting a waterproof structure. The waterproof structure includes structural sealant, and the structural sealant is set at the joints between the limit angle steel, the structural beam, and the ALC exterior wall panel.

[0009] Furthermore, it also includes step four: setting a thermal insulation layer. The thermal insulation layer is fixed on the exterior wall surface corresponding to the structural beam and extends to the ALC exterior wall panels on both sides of the structural beam.

[0010] Furthermore, in step three, the waterproof structure also includes a polyurethane film waterproof layer. The polyurethane film waterproof layer is set between the thermal insulation layer, the ALC exterior wall panel, and the structural beam and combines with the structural sealant to form a multi-level waterproof barrier.

[0011] Furthermore, in step one, the limit angle steel is set to be of full length to provide continuous support and limitation for the subsequent installation of wall panels. Description of the Drawings

[0014] Example 1 Example 1 is basically as shown in the appendix Figure 1 shown, such as Figure 1 shown, a connection method between a non-masonry exterior wall panel and a main structure, such as Figure 1 shown, includes the following steps: Step 1: Set up the connection structure, such as Figure 2 、 Figure 3 shown, the connection structure includes a limit angle steel 21 and a number of expansion bolts 22. After the main structure is poured and meets the conditions for installing the exterior wall protection system, the continuously arranged limit angle steel 21 is fixed on the structural beam 11 through the expansion bolts 22 to form the connection structure of the wall panel. The distance between adjacent expansion bolts 22 is less than or equal to 600 mm. At the same time, the limit angle steel 21 is used to position the exterior wall panel 12 and prevent the exterior wall panel 12 from tilting outwards. Specifically, the expansion bolt 22 is an M12 expansion bolt 22, and the angle steel 21 is a continuously arranged angle steel 21 of L63*63*6. The distance between adjacent expansion bolts 22 is 600 mm. The continuously arranged angle steel 21 can provide continuous support and limit for the subsequent installation of the wall panel, preventing the wall panel from overturning during installation; the M12 expansion bolts 22 with a distance of 600 mm ensure the connection strength between the angle steel 21 and the structural beam 11, guarantee the stability of the angle steel 21, and provide a stable installation surface for the subsequent installation work of the wall panel to position the subsequent installation work of the exterior wall panel 12 and prevent the exterior wall panel 12 from tilting outwards; Step 2: Wall panel installation. Lift and install the ALC exterior wall panel 12. After adjusting the verticality and flatness of the ALC exterior wall panel 12, the connection structure further includes a hook bolt 23. The wall panel is fixed on the limit angle steel 21 through the hook bolt 23, and the hook is located outside the wall panel. When fixing, first lap the hook of the hook bolt 23 on the angle steel 21 and weld it to the angle steel 21. Then, a connection hole 121 is opened on the indoor side of the ALC exterior wall panel 12. The connection hole 121 penetrates the ALC exterior wall panel 12 and is adapted to the bolt body of the hook bolt 23; then, the bolt body passes through the connection hole 121 and the ALC exterior wall panel 12 is fixedly connected to the limit angle steel 21 through the bolt body.

[0015] Example 2 Example 2 is basically the same as Example 1, except that it further includes Step 3: Set up a waterproof structure. The waterproof structure includes a structural sealant. The structural sealant is arranged at the joints between the limit angle steel 21 and the structural beam 11 and the ALC exterior wall panel 12, and the thickness of the sealant layer is not less than 1 mm.

[0016] Example 3 On the basis of Embodiment 2, it further includes Step Four: setting a thermal insulation layer 3, which is fixed on the outer wall corresponding to the structural beam 11 and extends to the ALC exterior wall panels 12 on both sides of the structural beam 11.

[0017] In Step Three, the waterproof structure further includes a polyurethane film waterproof layer, which is arranged between the thermal insulation layer 3, the ALC exterior wall panel 12 and the structural beam 11 and combines with the structural sealant to form a multi-level waterproof barrier.
