Description

Technical Field

[0001] This invention relates to the technical field of integrated exterior wall panel corner assembly and connection devices, and in particular to a method for splicing and connecting two adjacent exterior wall panels at a 45-degree oblique angle at a 90-degree corner of an integrated exterior wall panel. Background Technology

[0002] With the continuous in-depth research on integrated external wall panels, the improvement of wall panel design theory, the improvement of wall panel node types, and the improvement of wall panel installation technology, how to ensure the function and installation quality of the enclosure wall panels without damaging the wall panels or impairing their functionality is a problem that must be solved.

[0003] Existing prefabricated building exterior wall panels use right-angle joints, meaning one wall panel's flat surface connects to the end of another wall panel. There are three main types of integrated exterior wall corner joints on the market: 1. Right-angle joint: One wall panel's flat surface connects perpendicularly to the end of another wall panel. However, for exterior wall panels with decorative surfaces, the finishing process of one wall panel's end needs to be considered separately, requiring on-site re-processing of the decorative surface. It's difficult to achieve a smooth and uniform facade at the joint. 2. Corner joint: The wall panel at the corner needs to be processed into a non-standard wall panel, increasing manufacturing difficulty and cost. 3. Joint of two flat wall panels with one corner wall panel (non-standard wall panel): This requires an additional right-angle wall panel and an additional joint seam, increasing cost and construction difficulty.

[0004] The wall gaps in these wall panel connection methods need to be sealed with polyethylene foam rods, and then sealed with sealant on the outside for waterproofing. This is difficult to do and the process is complicated. On-site construction also requires the use of suspended railings or scaffolding before the exterior finish is sprayed and the gaps are sealed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of complex processing, high cost, large deformation, low precision, bulkiness and difficulty in operation of the existing design of 90-degree corner exterior wall panels, as well as the problems of sealing, leakage, waterproofing, heat insulation, sound insulation and cracking of exterior wall panel joints.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The method for splicing and connecting integrated exterior wall panels at 90-degree corners and 45-degree beveled angles includes the following steps:

[0008] Step 1: Hoist a prefabricated lightweight decorative integrated exterior wall panel to the location where the corner wall panel needs to be installed, and fix it through the prefabricated connecting structure;

[0009] Step 2: Clean the slope and drainage cavity of the fixed prefabricated lightweight decorative integrated exterior wall panel, and keep the base layer dry;

[0010] Step 3: Clean the slope and drainage cavity of the other prefabricated lightweight decorative integrated exterior wall panel that requires a 90-degree turn, and keep the base dry. After cleaning the base, apply the waterproof sealant strip to the cleaned slope.

[0011] Step 4: Apply waterproof sealing strips to the beveled surface of the other prefabricated lightweight decorative integrated exterior wall panel, hoist it to the corner position, and adjust and fix it using the prefabricated connecting structure until the through seam between the two beveled surfaces of the prefabricated lightweight decorative integrated exterior wall panel is uniform and vertical, thereby forming a waterproof cavity between the two beveled surfaces.

[0012] Preferably, the prefabricated lightweight decorative integrated exterior wall panel body is a ceramic aggregate foamed concrete decorative integrated exterior wall panel.

[0013] Preferably, the inclined plane is set at 45 degrees.

[0014] Compared with the prior art, the present invention provides a method for splicing and connecting integrated exterior wall panels at a 90-degree turn and a 45-degree bevel angle, which has the following advantages:

[0015] 1. This invention replaces the right-angle joint of two adjacent exterior wall panels at a 90-degree corner with a 45-degree beveled contact surface design. The joint has a waterproof function and a simple structure, solving the problem of high-quality installation of integrated expanded clay foam concrete exterior wall panels with decorative surfaces. It simplifies the process and saves costs. The 45-degree beveled contact installation method at the 90-degree corner of adjacent wall panels overcomes the problems of complex processing, high cost, large deformation, low precision, bulkiness, and difficulty in operation caused by existing wall panel assembly methods. It not only ensures the quality of adjacent wall panels at the 90-degree corner and the contact surface at the 45-degree corner, but also solves prominent problems such as ensuring the sealing of the exterior wall panels, preventing leakage, waterproofing, heat insulation, sound insulation, and cracking.

[0021] Example 1:

[0022] Please see Figures 1-2 The integrated exterior wall panel 90-degree corner 45-degree beveled contact surface splicing connection method, more specifically, a prefabricated lightweight decorative integrated exterior wall panel 90-degree corner wall panel end face 45-degree splicing connection method, includes the following steps:

[0023] A prefabricated lightweight decorative integrated exterior wall panel body 8 is hoisted to the position where the corner wall panel needs to be installed, and fixed by the prefabricated connecting structure;

[0024] Clean the base layer of the fixed prefabricated lightweight decorative integrated exterior wall panel body 8, including the inclined surface 801 and the water-pouring cavity 802, and keep the base layer dry.

[0025] Clean the slope 801 and water-pouring cavity 802 of the other prefabricated lightweight decorative integrated exterior wall panel body 8 that requires a 90-degree turn, and keep the base dry. After the base is cleaned, attach the waterproof sealing strip 9 to the cleaned slope 801.

[0026] Apply waterproof sealing strip 9 to the inclined surface 801 of the other prefabricated lightweight decorative integrated exterior wall panel body 8, hoist it to the corner position, and adjust and fix it through the prefabricated connection structure until the through seam between the inclined surfaces 801 on the two prefabricated lightweight decorative integrated exterior wall panel bodies 8 is uniform and vertical, so that a waterproof cavity 10 is formed between the two inclined surfaces 801.

[0027] The prefabricated lightweight decorative integrated exterior wall panel body 8 is a ceramsite foamed concrete decorative integrated exterior wall panel;

[0028] The slope 801 is set at 45 degrees.

[0029] This invention simplifies the construction and installation process by using a 45-degree bevel joint at the 90-degree corner of adjacent wall panels. This method is simple, convenient, and improves installation efficiency while ensuring the quality of the wall panel joints. The 45-degree bevel joint utilizes fire-resistant, heat-insulating, and sound-insulating strips and a structure for secondary waterproofing. The sealing structure, tightly fitted waterproof strips, and drainage cavity structure solve the problems of ensuring the insulation, heat insulation, sound insulation, fireproofing, waterproofing, mildew prevention, and frost resistance of the multi-functional integrated 90-degree corner wall panel. It eliminates the need for irregularly shaped wall panels, separate corner wall panels, and decorative surface treatment. This easily ensures a neat, clean, and complete exterior shape for the enclosure wall panels, and eliminates the need for subsequent waterproofing and exterior finishing work using suspended platforms or scaffolding.
