Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a large-scale protruding composite building exterior wall structure and its construction method. Background Technology

[0002] In the context of the rapid development of urban industrial transformation, traditional industrial plants can no longer meet the requirements of corporate image display. Urban "industrial buildings on the upper floors" projects have set higher standards for the aesthetics of the facade. However, industrial buildings generally have larger column spacing, higher floor height, and more complex facade changes, which places higher demands on architectural design and construction.

[0003] Current technologies for constructing complex building facades to accommodate urban industrial structures often employ either aerated concrete blocks (or ALC panels) combined with external framing and aluminum panels, or metal sandwich panels with added aluminum panel designs. However, the aerated concrete block (or ALC panel) combined with external framing and aluminum panel design suffers from low assembly precision, long construction cycles, high difficulty, and significant safety and quality risks. The metal sandwich panel with added aluminum panel designs is typically used for small decorative elements, where the metal sandwich panel is formed in a single process. Therefore, for larger protruding elements, a single-step forming is not feasible, and installation is difficult, posing significant safety and leakage risks, and resulting in high costs.

[0023] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a large-scale protruding combined building exterior wall structure provided in an embodiment of the present invention; Figure 2 This is a structural schematic diagram of a large-scale, outwardly convex modular building exterior wall structure provided in another embodiment of the present invention. Figure 1 This can also be understood as a horizontal sectional view of the external wall structure of the convex large-shaped combined building provided in an embodiment of the present invention; Figure 2 It can also be understood as a vertical sectional view of the external wall structure of the convex large-shaped combined building provided in an embodiment of the present invention.

[0024] The externally projecting, large-shaped modular building exterior wall structure provided in this embodiment of the invention includes an inner keel support 1, a metal insulation layer 2, a window assembly 3, a conversion assembly 4, an outer keel support 5, and an outer decorative layer 6. The inner keel support 1 is used to connect with the main building structure, and the metal insulation layer 2 and the window assembly 3 are disposed on the inner keel support 1. The conversion assembly 4 passes through the metal insulation layer 2, with one end connected to the inner keel support 1 and the other end connected to the outer keel support 5. The outer decorative layer 6 is disposed on the outer keel support 5.

[0025] In this embodiment, refer to Figure 1 and Figure 2 The external convex shape modular building exterior wall structure provided in this embodiment consists of an inner keel support 1, a metal insulation layer 2, a window assembly 3, a conversion assembly 4, an outer keel support 5, and an outer decorative layer 6.

By connecting the outer keel support and the inner keel support through a conversion component, a set of keel supports is shared, which improves installation efficiency and reduces costs. Furthermore, the conversion component transmits the force of the outer keel support to the inner keel support and then to the main building structure, avoiding damage to the insulation system and improving safety and waterproof performance.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
