[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 7 The present invention provides a technical solution: a steel component based on a building curtain wall, comprising:

[0028] The basic steel body 2 and the assembly steel body 3 with a raised portion are slidably docked, and the two side walls of the basic steel body 2 are integrally formed with side panels 11. The basic steel body 2 and the assembly steel body 3 form an I-shaped steel structure; two symmetrical concave spaces are formed between the I-shaped steel structure and the side panels 11 for carrying and limiting the glass unit 1; the concave space can adjust its volume according to the thickness of the glass unit 1 so that the inner wall of the assembly steel body 3 fits the outer wall of the glass unit 1; a release structure for injecting flexible sealant into the concave space is designed in the assembly steel body 3; a locking structure is installed on the basic steel body 2 to keep the assembly steel body 3 and the glass unit 1 in contact.

[0029] By designing a variable concave space, it is convenient for constructors to embed and install the glass unit 1. When the installation is completed, the positions of the two assembled steel bodies 3 can be locked by the locking structure, so that the inner wall of the assembled steel body 3 can be fitted and locked with the outer wall of the glass unit 1. The I-shaped steel structure has excellent load-bearing and compressive resistance, which is sufficient to be applied to curtain wall systems. The locking method of fitting can avoid stress damage caused by rigid connection. At the same time, the degree of fitting can also be adjusted by the locking structure, so as to adjust it according to the conditions faced by different buildings. Secondly, the release structure can inject flexible sealant into the bottom of the concave space to form an insulating layer, which can not only improve the overall sealing protection capability, but also the flexible insulating layer can avoid damage caused by displacement of the glass unit 1.

[0030] The base steel body 2 is connected to the building wall or floor away from the outer wall of the glass unit 1 .

[0031] In a preferred embodiment, the release structure includes recessed cavities 5 formed on the inner walls of the base steel body 2, the assembly steel body 3, and the side panels 11. When the concave space is locked to the glass unit 1, the multiple recessed cavities 5 are connected end to end to form a closed-loop molding path. The lowest point of the molding path is in the same plane as the inner bottom of the concave space. The assembly steel body 3 is internally designed to inject waterproof glue into the molding path. Figure 3 、 Figure 4 and Figure 5 In this embodiment, when the glass unit 1 is located in the concave space, the glass unit 1 will fit with the outer walls of the basic steel body 2, the assembly steel body 3 and the side panel 11. At this time, the opening of the molding glue channel will be blocked by the glass unit 1, thereby preventing the escape of the waterproof glue and affecting the final molding state. Moreover, since the lowest point of the molding glue channel is in the same plane as the inner bottom of the concave space, the insulation layer becomes a frame-shaped structure, thereby isolating the external environment from the internal environment. At the same time, the self-flow of the glue makes the molding quality of the insulation layer better and improves the sealing and protection ability of the steel structure.

[0032] Based on the embodiment of the release structure, the pump source includes a limiting groove opened inside the assembly steel body 3, and a capsule 6 is installed inside the limiting groove. The output end of the capsule 6 has a guide channel 7, and the inner wall of the guide channel 7 is installed with a pressure-resistant film. When the pressure-resistant film is broken, the guide channel 7 and the recessed cavity 5 are connected. A steel block 8 is fixedly installed on the basic steel body 2, and the steel block 8 is slidably assembled in the limiting groove. When the concave space forms a locking fit with the glass unit 1, the compression of the capsule 6 by the steel block 8 can cause the pressure-resistant film to break. Please refer to Figures 2 to 5 In this embodiment, during the displacement process of the assembled steel body 3, the steel block 8 will squeeze the capsule 6 due to the relative movement between the steel block 8 and the capsule 6. When the glass unit 1 is limited and fitted, the capsule 6 will withstand the maximum pressure, and the pressure-resistant film will break over time, thereby releasing the waterproof glue after the glass unit 1 is limited.

[0033] Based on the embodiment of the release structure, an assembly groove 12 is provided on the raised portion of the basic steel body 2, and a guide steel plate 4 is integrally formed on the assembly steel body 3. The guide steel plate 4 is slidably assembled with the assembly groove 12, and the thickness of the guide steel plate 4 is less than the thickness of the raised portion. The raised portion serves as the waist of the I-shaped steel structure, and the thickness of the waist determines the load-bearing tolerance of the steel structure.

[0034] Furthermore, the locking structure includes a bolt threadedly assembled on the outer wall of the base steel body 2, one end of the bolt extends into the interior of the assembly groove 12, and the inserted end of the bolt is rotatably sleeved with the outer wall of the guide steel plate 4. When the bolt rotates, it can drive the guide steel plate 4 to slide inside the assembly groove 12. After the locking is completed, the bolt can be anchored by welding.

[0035] On the basis of the pump source embodiment, the outer walls of the basic steel body 2, the assembled steel body 3 and the side panels 11 are all provided with air guide grooves 14. When the concave space forms a fit and lock on the glass unit 1, the multiple air guide grooves 14 are first connected to form an air duct. The air duct is located above the recessed cavity 5. The outer wall of the assembled steel body 3 is provided with an external interface connected to the air duct. The external interface is connected to an external air pump with a pressure gauge. In this embodiment, after the insulating layer is formed, it is necessary to test the protective ability of the curtain wall unit, and the final test is air tightness. In order to enable the curtain wall system to withstand tests such as rain, a detection module is added to the steel component to test the ability of the insulation layer. Specifically, the air pump is turned on and its pressure value is detected. For example, the air pump injects a preset pressure of air into the air duct, and checks the degree of slow release of the pressure value per unit time, thereby judging the protective ability of the insulation layer.

[0036] Based on the embodiment of the release structure, the working legs of the assembly steel body 3 are smaller than the working legs of the basic steel body 2, and the upper and lower surfaces of the side panels 11 are flush with the upper and lower surfaces of the assembly steel body 3. The basic steel body 2 provides a larger support area for the glass unit 1. Although the assembly steel body 3 is smaller, through the cooperation of the upper and lower assembly steel bodies 3, the assembly steel body 3 also has sufficient locking ability to restrict the glass unit 1.

[0037] Based on the pump source embodiment, the glue stored inside the capsule 6 is nano-silicone waterproof glue, which can be formed into a flexible waterproof frame after molding. In order to alleviate the damage caused by stress, a waterproof frame is formed in the concave space, and the waterproof frame is a flexible structure. Due to the sequential arrangement of the I-shaped steel structure, both ends of the glass unit 1 can have a flexible waterproof frame as a buffer, thereby extending the service life of the glass unit 1. Secondly, the flexible waterproof frame also has good isolation ability, which blocks external humid air, water vapor or rainwater, thereby improving protection capabilities.

[0038] Furthermore, a resistive pressure film 13 is embedded in the inner wall of the basic steel body 2 above the concave space. The external pressure surface of the resistive pressure film 13 exceeds the inner wall plane of the basic steel body 2. The building curtain wall will be connected to the interconnection system, and the glass unit 1 will cause different pressures on the resistive pressure film 13 when facing different external environments. The pressure can better reflect the state of the glass unit 1 and can respond and make adjustments in time.

[0039] By utilizing the cooperation of the above structures, the glass unit 1 can be quickly docked and locked, and an insulating layer can be formed between the glass unit 1 and the concave space to improve the protection capability.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.
