Description

Technical Field

[0001] The present invention relates to the technical field of curtain walls, and particularly to a heat-insulating curtain wall for prefabricated buildings and an installation method thereof. Background Art

[0002] A curtain wall is a type of external maintenance structure of a building. Different from traditional masonry or concrete walls, it mainly consists of a panel and a support structure system, does not bear the load of the main structure, and only serves as an enclosure. The characteristic of a curtain wall is that it can provide good lighting, vision, and appearance effects for the building. With the development of technology, curtain wall design pays more and more attention to environmental protection and energy conservation, and its characteristics of heat insulation performance and heat preservation performance are gradually favored.

[0003] However, the special-shaped exterior of the existing curtain wall structure is mainly built by the erection of its brackets. Therefore, there are certain difficulties in the erection process. The amount of material released needs to be fully considered, and if the measurement is inaccurate, situations such as warping edges will occur, which is somewhat dangerous.

[0004] Therefore, it is necessary to provide a heat-insulating curtain wall for prefabricated buildings and an installation method thereof to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a heat-insulating curtain wall for prefabricated buildings and an installation method thereof, to solve the problems that the existing device is not easy to realize the assembly of the special-shaped building exterior wall and the manual operation is complex, and to realize the function of heat insulation and heat preservation of the curtain wall.

[0006] To achieve the above purpose, the present invention provides a heat-insulating curtain wall for prefabricated buildings, including an upper wall panel, a lower wall panel, a first supplementary block hinged to the upper wall panel through a first hinge, a second supplementary block hinged to the lower wall panel through a second hinge, and the first supplementary block and the second supplementary block are connected through a third hinge.

[0007] Preferably, the upper wall panel and the lower wall panel are symmetrically arranged, and the first supplementary block and the second supplementary block are symmetrically arranged.

[0008] Preferably, upper concave grooves are provided at the edges on both sides of the upper wall panel, lower concave grooves are provided at the edges on both sides of the lower wall panel, a length-adjustable telescopic strip is arranged between the upper concave grooves and the lower concave grooves, and the telescopic strip is connected to the upper concave grooves and the lower concave grooves through connecting rods.

[0009] Preferably, a positioning strip fixed by screws is arranged between the telescopic strips on both sides. The positioning strip is provided with a strip-shaped hole, and the positioning strip is always located at the middle position of the telescopic strip.

[0010] Preferably, a threaded rod is connected to a side of the third hinge away from the first supplementary block and the second supplementary block, and the threaded rod passes through the strip-shaped hole.

[0011] Preferably, a bolt for fixing the threaded rod is provided on a side of the strip-shaped hole away from the third hinge, and a flexible gasket for preventing electrochemical corrosion is provided between the bolt and the strip-shaped hole.

[0012] Preferably, the structures of the upper wall panel and the lower wall panel are both an inner layer of glass, a heat insulation layer, and an outer layer of glass.

[0013] Preferably, the heat insulation layer is one of a graphene layer, a silica aerogel heat insulation layer, or a polystyrene foam layer, and the materials of the inner layer of glass and the outer layer of glass are low-emissivity glass.

[0014] The present invention also discloses an installation method for a heat-insulating curtain wall for prefabricated buildings, including the following steps:

[0015] S1: Determine the folding angle required during installation. When the folding angle is 0°, only install the upper wall panel and the lower wall panel; when the folding angle is not 0°, use the threaded rod to push out the third hinge. After the folding surfaces of the first supplementary block and the second supplementary block are pushed out, determine the included angle between the first supplementary block and the second supplementary block at the third hinge.

[0016] S2: The telescopic strip between the upper wall panel and the lower wall panel is telescoped to determine the length, and the feed amount of the threaded rod is controlled by the bolt.

[0017] S3: Securely engage the upper wall panel and the lower wall panel with the cross beam and the column, and the single-layer installation can be completed.

[0018] The advantages and positive effects of the heat-insulating curtain wall for prefabricated buildings and its installation method of the present invention are:

[0019] 1. This application document uses low-emissivity glass to reduce heat transfer. Through the heat-insulating filler between the inner layer of glass and the outer layer of glass, it has a low thermal conductivity and good fire resistance. The combination of the two can be more environmentally friendly and energy-saving, meeting the requirements of green development.

[0020] 2. By filling the folding gap between the upper wall panel and the lower wall panel with the folding surfaces of the first supplementary block and the second supplementary block, a special-shaped effect can be achieved using a single curtain wall unit, eliminating the need to additionally build metal columns and cross beams, which is beneficial for cost savings.
