Description

Technical Field

[0001] This utility model relates to the technical field of thermally broken steel door and window profiles, and in particular to a mortise and tenon structure thermally broken steel door and window profile. Background Technology

[0002] Currently, thermally broken steel doors and windows on the market are mainly produced and installed using the following process: two open cold-formed steel profiles produced by roll forming are connected using non-metallic thermally insulated profiles, and then processed and connected using specialized equipment. This method of producing thermally broken steel door and window profiles results in high production costs, high assembly precision requirements, low strength, and complex operation. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a mortise and tenon structure thermal break steel door and window profile, which effectively solves the problems of high production cost and low assembly efficiency of thermal break steel doors and windows.

[0004] The technical solution to the technical problem is: a mortise and tenon structure thermally broken steel door and window profile, including a first steel profile and a second steel profile, the right end face of the first steel profile and the left end face of the second steel profile respectively cooperate to form the thermally broken surface of the door and window profile, and a composite fireproof and heat-insulating material is fixedly installed on the thermally broken surface of the door and window profile. The first and second steel profiles have mortises on their broken bridge surfaces. The composite fireproof and heat-insulating material has tenons extending from both ends. The tenons are inserted into the mortises to form a structure that fixes the composite fireproof and heat-insulating material to the first and second steel profiles.

[0005] Preferably, the first and second steel profiles are closed-end shaped tube structures.

[0006] Preferably, a heat insulation strip is provided between the tenon and the mortise, and the heat insulation strip is made of PA66 nylon heat insulation material.

[0007] Preferably, the composite fireproof and heat-insulating material has a fireproof shaped steel core and is covered with heat-insulating material on the outside.

[0008] This utility model is simple and ingenious, easy to use, and adopts a mortise and tenon structure, which can be installed without special equipment. It is easy to operate and can significantly reduce production costs. The fireproof and heat-insulating composite material connection and the internal fireproof special-shaped steel structure of the steel profile result in higher strength. Attached Figure Description

[0013] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 2 to 4 It is known that a mortise and tenon structure thermally broken steel door and window profile includes a first steel profile 1 and a second steel profile 2. The right end face of the first steel profile 1 and the left end face of the second steel profile 2 respectively cooperate to form the thermally broken surface of the door and window profile. A composite fireproof and heat-insulating material 3 is fixedly installed on the thermally broken surface of the door and window profile. The first steel profile 1 and the second steel profile 2 have mortises 4 on their broken bridge surfaces. The composite fireproof and heat-insulating material 3 has tenons 5 extending from both ends. The tenons 5 are inserted into the mortises 4 to form a structure in which the composite fireproof and heat-insulating material 3 is fixedly connected to the first steel profile 1 and the second steel profile 2.

[0015] In this utility model, the first steel profile 1 and the second steel profile 2 are closed-end special-shaped tube structures, which are stronger and more stable than existing open-end thermally broken steel profiles.

[0016] In practical use, this utility model Depending on the actual application location, the first steel profile 1 and the second steel profile 2 in different embodiments are selected. Then, the composite fireproof and heat-insulating material 3 is installed through a mortise and tenon structure. Since the composite fireproof and heat-insulating material 3 is connected to the steel profile through a mortise and tenon structure, it can be installed manually using existing tools without the need for special tools, which can reduce equipment investment and lower production costs.

[0017] A heat insulation strip 6 is provided between the tenon 5 and the mortise 4. The heat insulation strip 6 is made of PA66 nylon heat insulation material. The composite fireproof heat insulation material 3 is made of fireproof special-shaped steel inside and covered with heat insulation material on the outside. It has better heat insulation effect, fireproof, heat insulation, high quietness, wind resistance and cold resistance.

[0018] The specifications of the mortise 4 on the first steel profile 1 and the second steel profile 2 are unified with those of the tenon 5 on the composite fireproof and heat-insulating material 3, so that the installation can be carried out more accurately and stably, simplifying the operation and improving the installation efficiency.

[0019] Compared with the prior art, this utility model has the following advantages: the use of mortise and tenon structure for connection reduces the investment in special equipment, lowers production costs, simplifies installation steps, improves installation efficiency, and the steel profile of the closed-type tube can significantly improve strength, maintain stability, and achieve the effects of fireproofing, heat insulation, high sound insulation, wind resistance, cold protection, and high strength.
