Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of broken bridges, and particularly relates to a process technology for fireproof and heat-insulating strip profiles. Background Art
[0002] In recent years, the requirements for building doors and windows, partition walls, and curtain walls in the market have been continuously increasing. At present, heat-insulating profiles for building energy conservation generally adopt the technology of heat-insulating cold bridges to achieve the purpose of heat insulation and energy conservation. The internal broken bridge is the core component of the strip heat-insulating profile, reducing the heat transfer in the aluminum profile part; it is also the structural connecting part of the two aluminum profiles on both sides in the heat-insulating profile. Through its connection, the three parts of the heat-insulating profile become an integral whole, jointly bearing the load. Therefore, it is not simply regarded as a heat-insulating functional component.
[0003] As the only force-bearing and load-transferring structure, the strength and environmental adaptability of the heat-insulating strip determine the overall service life. However, most of the broken bridge heat-insulating strip materials in the market are nylon strip broken bridges. The existing nylon broken bridges have problems such as poor heat insulation effect, non-fireproof, large changes in the mechanical properties of the profiles at high and low temperatures, and poor stability. And they will deform or age at extreme temperatures, affecting the heat insulation effect. Secondly, due to the characteristics of the material itself, the nylon heat-insulating strip will show fatigue and damage after long-term use, and needs to be replaced in time to ensure the heat insulation effect.
[0004] At present, the width dimensions of some nylon heat-insulating strips in the market are too large, accounting for a large proportion in the overall structure, which instead leads to a reduction in its structural strength. The steel broken bridge with a moderate width can effectively improve the heat insulation performance of the overall system. Summary of the Invention
[0005] The present invention provides a steel broken bridge heat-insulating connecting profile, which can simultaneously solve the problems of heat insulation and fire prevention, has a delicate appearance structure, and can ensure the stability and strength of its broken bridge structure.
[0006] To achieve the above object, the present invention discloses the following technical content: A steel broken bridge heat-insulating connecting profile includes a profile; the profile includes a hollowed-out, grid-shaped profile and a profile return edge; both ends of the profile have return edges, the middle of the profile is hollowed out, the hollowed-out part is in the shape of a hill, the grid-shaped profile is wavy, and the profile return edge is in a C shape.
[0007] Further, the length of the hollowed-out part is 90 mm, and the corner radius is 1.5 mm; the middle of the hollowed-out part is triangular, and the triangular length is 24 mm, which can reduce heat insulation conduction while meeting stability.
[0008] Further, a bulge - reinforcing rib is provided in the middle of the grid-shaped profile 1, with a length of 33 mm, increasing the tensile strength of the profile structure.
[0009] Further, the profile return edge 2 is bent by a bending machine, with a vertical bending dimension of 5.1 mm and a horizontal bending dimension of 2.75 mm; it has a C-shaped structure.
[0010] Further, the material of the profile is galvanized steel.
[0011] Further, the profile thickness is 1 mm and the formed width is 30 mm.
[0012] Beneficial technical effects: The present invention inherits the excellent properties of steel profiles, has high strength and corrosion resistance, a long service life, and also has fireproof and heat insulation properties; it solves the problems of the existing nylon heat insulation strips in the market that are not fireproof, have poor heat insulation effect, poor elasticity, and are prone to cracking. The steel broken bridge heat insulation strip has a large structural strength, high precision, accurate profile processing structure, excellent fireproof and heat insulation performance, long durability, and will not have problems such as thermal deformation, resulting in poor slot joint tightness and leakage.
