Description

Technical Field

[0001] This utility model relates to a prefabricated energy-saving integrated panel for reducing stress and an insulated exterior wall decoration structure. Background Technology

[0002] Exterior wall energy-saving panels possess excellent thermal insulation properties, effectively reducing building energy consumption. For example, integrated exterior wall insulation and decoration panels can significantly reduce heating energy consumption in winter and decrease the frequency of air conditioning use in summer, thereby saving energy expenditures. These panels typically employ a combination of adhesive and anchoring installation, making construction simple and quick, unrestricted by weather, season, or geographical environment. This significantly shortens the construction cycle and reduces construction costs. Exterior wall energy-saving panels offer diverse aesthetic designs to meet the needs of different architectural styles and enhance the overall aesthetics of buildings.

[0003] Traditional energy-saving exterior wall panels are typically fixed to the wall using adhesive, anchoring, or a combination of both. The panels are fixed at both ends to two opposing keel frames, and the insulation layer is placed within the cavity formed by the keel frames, panels, and wall. However, the installation of traditional energy-saving exterior wall panels with screws is difficult to control, and wet installations are prone to quality issues such as detachment and leakage. Furthermore, the insulation layer, installed between the panel and the wall, is susceptible to deformation and damage due to thermal expansion and contraction. Utility Model Content

[0025] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-4 As shown, this utility model provides a prefabricated energy-saving integrated panel for reducing stress, including a frame 1 and a panel 2. The frame 1 is fixed to the wall with bolts, and the two ends of the panel 2 are fixed to two opposing frames 1 with screws. An insulation layer 3 is placed in the cavity formed by the frame 1, the panel 2, and the wall. The insulation layer 3 is made of thermosetting board, melamine board, phenolic board, or rock wool, etc., and is bonded to the back of the panel 1 with adhesive or tape to form a panel with a certain degree of deformation resistance. The panel 2 is made of stainless steel sheet / zinc-aluminum-magnesium sheet / aluminum-magnesium-manganese sheet / galvanized sheet, etc., with surface embossing or coating treatment (such as imitation stone, fluorocarbon paint, plating). A heat insulation pad 4 is provided between the contact surfaces of the panel 2, the wall, and the frame 1. Among them, a sealing layer 5 is provided between the insulation layer 3 and the wall. Both the sealing layer 5 and the insulation layer 3 are made of insulation material and placed in the corresponding position in the cavity. The insulation layer 3 and the panel 2 form an integral panel and are processed and produced in the factory. The keel frame 2 and the sealing layer 5 are completed on the construction site. There is a very small gap between the sealing layer 5 and the insulation layer 3 during installation so that the whole can have room for deformation.

[0027] like Figure 5As shown, the insulation layer 3 is laminated with the panel during the actual production process. Grooves extending in different directions are provided on both the front and back sides. By setting several grooves, the entire insulation layer area can be divided into small areas to reduce the stress caused by thermal expansion and contraction. At the same time, grooves in different directions are set on the front and back sides so that stresses in different directions are generated on the front and back sides of a board during thermal expansion and contraction. Ultimately, the stresses generated on the front and back sides cancel each other out, reducing the cumulative deformation effect and thus reducing the deformation damage caused by stress.

[0028] Preferably, the front side of the insulation layer 3 is provided with a plurality of longitudinal grooves 301, and the back side is provided with a plurality of transverse grooves 302; or, the front side of the insulation layer 3 is provided with a plurality of transverse grooves 302, and the back side is provided with a plurality of longitudinal grooves 301. The grooves on the front and back sides of the insulation layer 3 can also be inclined and not horizontally transverse or vertically longitudinal, as long as they can divide the insulation layer and the intersection of the projections of the front and back grooves can reduce stress, they are all within the scope of this utility model.

[0029] like Figure 6 As shown, panel 2 includes a box 201 with an opening on the back. Side panels 202 are provided around the opening of box 201. Opposite side panels 202 are fixed to two opposite keel frames 1. The side panels 202 are provided with fixing holes 203 for screws to pass through and fix to the keel frame 1.

[0030] In this design, the fixing holes 203 are strip-shaped. When two panels 2 are joined, adjacent side panels 202 are stacked on top of each other, and the fixing holes 203 on adjacent side panels 202 intersect each other perpendicularly. In this embodiment, the fixing holes 203 on opposite sides of the panel are arranged in a strip-like direction, so that screws can pass through the holes formed at the intersections and be fixed to the frame 1.

[0031] Panel 2 expands and contracts due to thermal expansion and contraction caused by weather changes. When the two panels are spliced ​​together, they are fixed to the frame with screws through the strip-shaped fixing holes. Once the panels expand and contract, they can expand and contract along the strip length of the fixing holes 203. This ensures that each panel can expand and contract without affecting the fixing position of the screws. To a certain extent, this solves the problem of panel deformation and damage caused by the direct use of screws in the existing technology, which cannot adapt to the expansion and contraction of the panels due to thermal expansion and contraction.

[0032] As one embodiment of this utility model, the cross section of the keel frame 1 is "C" shaped. The two wings of the "C" shaped keel frame 1 have different lengths. The longer wing is fixed to the wall by bolts, and the shorter wing is attached to the side plate 202 and fixed by screws.

[0033] As another embodiment of the utility model, the cross-section of the keel frame 1 is an Ω-like shape, the bottom opening of the Ω-like shape faces the wall, and the two side wings are respectively fixed to the wall by bolts, the top of the Ω-like shape is attached to the side plate 202 and fixed by screws, and a plugging layer 5 is filled in the bottom opening of the Ω-like shape.

[0034] As Figure 7 shown, in another aspect of the utility model, there is also provided a thermal insulation decorative exterior wall, which is formed by mutually splicing the above-mentioned prefabricated energy-saving integrated plate for reducing stress. In the splicing process, the side plates 202 between two adjacent panels 2 are arranged in a stacked manner, screws pass through the fixing holes 203 and are then fixed on the keel frame 1, and the keel frame 1 is also fixed on the wall by bolts, finally forming the entire thermal insulation decorative wall surface.

[0035] The above description is only a preferred embodiment of the utility model, and is not used to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
