Description

Technical Field

[0001] This invention relates to the technical field of thermal insulation and decorative wall panels, and in particular to a double-cavity steel keel thermal insulation and decorative integrated exterior wall panel and its preparation method. Background Technology

[0002] Similar to traditional exterior walls, they generally take the following forms:

[0003] (1) The wall is made of inorganic lightweight wall panels, which are used as the external wall cladding components. Insulation materials are installed on the wall on site, and then a decorative layer is applied.

[0004] (2) The wall is made of reinforced lightweight exterior wall panels manufactured in a factory, with an additional thermal insulation and decorative layer on the outside. The wall panels themselves are produced by cast-in-place concrete reverse pouring process. During the cast-in-place process, a protective finishing layer is required. The wall panels are prone to cracking and require curing.

[0005] (3) The wall structure uses a steel frame with cast-in-place lightweight infill material inside, and an additional thermal insulation and decorative layer on the outside. The wall panels also use cast-in-place concrete, which also presents problems with the protection and curing of the finishing layer, and cannot form a cavity insulation structure.

[0006] (4) If the exterior wall of the above traditional method needs to be made into horizontal or vertical shapes, a separate keel is required. This integrated wall can be made into shape in one piece by steel frame without the need for separate installation. It also has the characteristics of light weight, excellent seismic performance, high thermal insulation efficiency, diverse material selection, high integration, and economic rationality.

[0007] (5) Preparation: The integrated wall system uses a steel frame as the supporting structure. The exterior wall decoration mechanism is installed on the outdoor side, and the sound insulation mechanism is installed on the indoor side. Two cavities are reserved between the two. The wall panels can be vertically and dry-manufactured, occupying little production space and easily achieving automated production. There is no need to consider the protection and maintenance of the finishing layer during the production process, and there are no load requirements for the prefabricated sound insulation decorative panels.

[0008] (6) In terms of effectiveness: The relatively still air within the enclosed cavity of this wall is effectively utilized as insulation material, providing thermal insulation. Furthermore, the thermal insulation device in the middle divides the enclosed cavity into two independent enclosed cavities, nearly doubling the effect of air participation in thermal insulation. The double-sided reflective film-coated insulation material in the thermal insulation mechanism significantly reduces heat transfer through radiation, thus enhancing the effectiveness of the wall's insulation material. Summary of the Invention

[0009] To solve the above-mentioned technical problems, this invention provides a closed cavity formed by a supporting force-bearing mechanism in conjunction with an outdoor outer enclosure mechanism and an indoor sound insulation mechanism. A thermal insulation mechanism then divides the cavity between the outdoor outer enclosure mechanism and the indoor sound insulation mechanism into two cavities. The air in these two cavities acts as insulation material to block heat conduction. Together with the outer enclosure mechanism, sound insulation mechanism, and thermal insulation mechanism, they provide thermal insulation for both the interior and exterior of the building. Simultaneously, a double-sided composite reflective film in the thermal insulation mechanism reflects heat radiation. Furthermore, the outer enclosure mechanism and the sound insulation mechanism can be optionally equipped with additional insulation material, and decorative fabrics can be optionally added or omitted. This results in a highly practical "double-cavity steel keel insulated and decorative integrated exterior wall and its preparation method."

[0010] The double-cavity steel keel thermal insulation and decorative integrated exterior wall of the present invention includes a supporting force-bearing mechanism, an external enclosure mechanism on the outdoor side, a sound insulation mechanism and a heat insulation mechanism on the indoor side. The external enclosure mechanism on the outdoor side, the sound insulation mechanism and the heat insulation mechanism on the indoor side are all installed on the supporting force-bearing mechanism, and the heat insulation mechanism is located between the external enclosure mechanism on the outdoor side and the sound insulation mechanism on the indoor side.

[0017] The supporting structure, together with the exterior enclosure on the outdoor side and the sound insulation structure on the indoor side, forms a closed cavity. Then, the thermal insulation structure divides the cavity between the exterior enclosure on the outdoor side and the sound insulation structure on the indoor side into two cavities. The air in the two cavities acts as insulation material to block heat conduction. Together with the exterior enclosure, sound insulation structure, and thermal insulation structure, the structure provides thermal insulation for both the interior and exterior of the building.

[0025] Preferably, the sound insulation mechanism includes a sound insulation board fixing keel and a sound insulation board. The sound insulation board is installed on the steel frame through the sound insulation board fixing keel, and the sound insulation board is located on the indoor side of the steel frame; thereby improving the sound insulation effect of the wall.

[0026] Preferably, the external enclosure mechanism includes an external wall decorative panel fixing keel, external wall decorative panel hangers, and decorative panels. The decorative panels are installed on the steel frame through the external wall decorative panel fixing keel and external wall decorative panel hangers, and the decorative panels are located on the outdoor side of the steel frame; thereby improving the aesthetics of the wall and its thermal insulation and sound insulation performance.

[0027] Preferably, the heat insulation mechanism is located in the steel frame, and the steel frame between the outdoor decorative panel and the indoor sound insulation panel is divided into two closed cavities to form a closed cavity; thereby improving the heat insulation effect of the wall.

[0028] Preferably, the heat insulation mechanism includes a double-sided reflective film composite insulation material and a heat insulation mechanism fixing keel. The double-sided reflective film composite insulation material is installed on the steel frame through the heat insulation mechanism fixing keel. The material of the heat insulation mechanism is a double-sided aluminum foil sandwich insulation board, insulation felt, or glass wool; thereby improving the heat insulation effect of the wall.

[0029] The method for preparing the double-cavity steel keel thermal insulation and decorative integrated exterior wall of the present invention is characterized by comprising the following steps:

[0030] Step 1: Preparation of the supporting force mechanism:

[0031] S1. Steel cutting;

[0032] S2. Assemble the cut materials by welding, riveting, or connecting with high-strength bolts.

[0053] S8. Install the interior side wall decoration materials onto the sound insulation board.

[0054] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0055] 1. Thermal insulation:

[0056] The supporting structure, together with the exterior enclosure and the sound insulation structure, forms a closed cavity. A thermal insulation structure divides this cavity into two equal-sized cavities. The air within these cavities acts as insulation, blocking heat conduction. Together with the exterior enclosure, sound insulation, and thermal insulation structure, they provide thermal insulation for both the interior and exterior of the building. A double-sided reflective film in the thermal insulation structure reflects heat radiation. Furthermore, the exterior enclosure and sound insulation structure can be optionally equipped with additional insulation materials, and decorative fabrics can be added or omitted as needed.

[0057] Relatively still air is a high-insulation material with extremely low thermal conductivity. By using this relatively still air as a thermal insulation material, the thermal insulation efficiency of the integrated exterior wall is improved, thus enhancing the thermal insulation performance of the integrated wall.

[0058] 2. Regarding weight:

[0059] The integrated wall system is lightweight because it uses steel keel material instead of reinforced concrete to support the external enclosure and sound insulation structure, as well as to withstand external forces such as seismic forces and wind loads. Therefore, when applied to a steel frame main structure system, it can reduce the amount of steel used in the main structure.

[0060] 3. Design aspects:

[0061] This integrated wall system uses steel keel as the supporting structure. Steel keel has the characteristic of being highly malleable. After being cut, it can be welded, bolted, or riveted to create flexible and varied shapes to meet the design requirements of various building facades. Attached Figure Description
