L-shaped edge sealing aluminum profile

Abstract

The invention belongs to the technical field of aluminum profiles, and particularly relates to an L-shaped edge sealing aluminum profile. The L-shaped edge sealing aluminum profile comprises a fixed bottom plate and a side baffle. The side baffle is fixed to the side of the fixed bottom plate. The L-shaped edge sealing aluminum profile is characterized in that a damping cavity is formed in the fixed bottom plate, and a sandwich layer is inserted into the damping cavity; the sandwich layer adopts a closed-hole foam aluminum material, one end of the sandwich layer is uniformly provided with a plurality of inserting cavities, and inserting cross beams are arranged in the plurality of inserting cavities; the other end of the sandwich layer is uniformly provided with a plurality of inserting blocks, and the inserting blocks are made of foam aluminum materials; the plurality of inserting blocks are correspondingly inserted into the plurality of inserting cavities, sliding clamping grooves are formed in the two sides of the plurality of inserting blocks, and the sliding clamping grooves are in sliding inserting fit with the inserting cross beams; and a stepped hole is formed in the lateral side of the fixed bottom plate; threaded holes are formed in the plurality of inserting cavities; fixing bolts are connected in the threaded holes in a threaded manner; and the rigidity and firmnessof the splicing positions of spliced edge sealing aluminum profiles are improved, and the overall weight of the edge sealing aluminum profiles is reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum profiles, in particular to an L-shaped edge-sealing aluminum profile. Background technique [0002] With the improvement of living standards, aluminum alloys used in some mid-to-high-end high-rise buildings and well-off residences have higher requirements for their performance and surface quality. At present, the popular aluminum door frames and doors in the market have exquisite appearance and are not easy to rust. However, the cavity of the heat insulation parts used is small, so that the aluminum material accounts for a large proportion in the overall material, which increases the price of the aluminum material and greatly increases the cost of the material. Because the aluminum profile has the advantages of light weight and strong resistance It is widely used in buildings. [0003] The Chinese patent discloses an L-shaped edge-sealing aluminum profile. The patent application number is 201811...

Problems solved by technology

[0004] Although the above-mentioned aluminum profile has good sound insulation effect, water tightness, and shock absorption performance; but because it is a method of pouring polyurethane into the cavity of the aluminum profile to enhance the effect of sound insulation, sealing and shock absorption of the aluminum profile; but when multiple aluminum profiles When the profiles are spliced ​​together, the overall weight of the spliced ​​aluminum profiles will be increased, making it more troublesome to install the aluminum profiles; at the same time, when the aluminum profiles are spliced ​​with each other, splicing holes need to be opened on the cast polyurethane, which will lead to mutual splicing The poor stability and rigidity of the joints of aluminum profiles, which in turn affects the safe use of aluminum profiles
