Super-large aluminum profile decorative louver and machining technology thereof

Abstract

The invention discloses a super-large aluminum profile decorative louver and a machining technology thereof. The decorative louver is formed by assembling and joining of two kinds of aluminum profiles, namely, a large-louver aluminum profile and a glue-injecting aluminum profile. The glue-injecting aluminum profile comprises a connection part A and a connection part B, wherein the front end of theconnection part A is connected with the large-louver aluminum profile, and the rear end of the connection part B is connected with a curtain wall. A glue-injecting opening is formed in a middle connection part. The glue-injecting opening is filled with structural glue. U-shaped inserting parts are arranged on both edges of the front end of the connection part A. A well-matched inserting groove isformed in the rear end of the large-louver aluminum profile. The machining technology comprises the steps that the two kinds of aluminum profiles are molded separately through special dies and an extruding machine; a first aluminum profile is subjected to glue-injecting by the way of double-layer glue injecting and simultaneous glue injecting from glue injecting openings formed in the two sides;and after the surveying and setting out on a construction site is carried out, according to the actual size on the site, the two kinds of aluminum profiles are cut in a blanking mode, and then after the two kinds of aluminum profiles are jointed together, installation is carried out. The machining technology can machine large-span and super-large aluminum alloy decorative louvers with the length of up to 9 meters, and the integrity is good, the strength is high, and the heat insulation performance is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building material processing, and relates to the processing of decorative building materials, in particular to a super-large aluminum profile decorative louver and its processing technology. Background technique [0002] Existing airport exterior decoration projects mostly use super-large aluminum alloy decorative louvers (external wall decorative louvers), whose cross-sectional size can reach 550mm, as the main force-bearing structure and also has sunshade function. However, the traditional aluminum alloy decorative louver technology still exists. Big limitations. [0003] First of all, due to the immature technical limitations of aluminum profile processing plants in the past, the traditional aluminum alloy decorative louvers do not have the function of heat insulation, so their use has certain regional limitations. In the north where the winter climate is relatively cold, traditional aluminum alloy dec...

AI Technical Summary

Problems solved by technology

[0002] Existing airport exterior decoration projects mostly use super-large aluminum alloy decorative louvers (external wall decorative louvers), whose cross-sectional size can reach 550mm, as the main force-bearing structure and also has sunshade function. However, the traditional aluminum alloy decorative louver technology still exists. big limitations

[0003] First of all, due to the immature technical limitations of aluminum profile processing plants in the past, the traditional aluminum alloy decorative louvers do not have the function of heat insulation, so their use has certain regional limitations. In the north where the winter climate is relatively cold, traditional aluminum alloy decorative louvers The louvers are unusable and not insulated

[0004] Secondly, the traditional aluminum alloy decorative louvers are used as the main force-bearing structure. Considering its structural strength, the general length is controlled within the range of 4 meters. It is used in large-space public buildings, and the space utilization rate is small, which will hinder the vision to a certain extent. unsightly
