[0002] Steel structure houses are recognized as a green and environmentally friendly structural system that adapts to the development of the housing industry. However, due to the fact that the thermal conductivity of steel itself is more than thirty times higher than that of concrete, the problem of heat preservation and energy conservation in steel structure houses is more severe. The problem of energy conservation of the thermal bridge of the beam and column in steel structure houses in hot summer and cold winter regions has always been a technical problem that is difficult to solve. Currently, in the market, most of them prevent the problem of heat conduction by filling heat preservation materials in the web of the H-shaped steel beam. However, the difference in the thermal expansion and contraction reactions of the steel structure and the heat preservation materials due to the influence of climate conditions is very large, resulting in the cracking and detachment of the heat preservation layer from the H-shaped steel, affecting the heat preservation and energy conservation effect of the building and the aesthetics of the structure.

Steel wires are wound around the metal hooks at the edge positions of the two wing plates on one side of the web.

[0006] Preferably, on both sides of the steel beam body and outside the steel wires, there are installed wire meshes.

[0021] Refer toFigures 1-3 , a heat-insulating fixing structure for an H-shaped steel beam, comprising a steel beam body 1 with an H-shaped cross-section. On both surfaces of the web of the steel beam body 1, tension anchor bolts 2 extending outward and arranged uniformly are installed. Specifically, the tension anchor bolt 2 includes a rubber rod 201 and a sleeve 202 installed at the end of the rubber rod 201. The front end of the rubber rod 201 has a spike part, and a plurality of barbs 203 are arranged in the circumferential direction of the rubber rod 201. The rubber rod 201 is connected to the sleeve 202 by a threaded connection. The sleeve 202 is fixed on the surface of the web of the steel beam body 1. Among them, the sleeve 202 is installed on the surface of the web of the steel beam body 1 by welding. The inside of the sleeve 202 has internal threads, and the other end of the rubber rod 201 has external threads. The rubber rod 201 and the sleeve 202 are connected by a threaded connection. During actual work, the tension anchor bolt 2 can penetrate the heat-insulating material in the web of the steel beam body 1. On the one hand, the tension anchor bolt 2 is used for support, and on the other hand, the barbs 203 on the tension anchor bolt 2 can be used to prevent the heat-insulating material from falling off, having the advantage of making the structure of the heat-insulating material stable.

[0022] Specifically, at least two rows of the tension anchor bolts 2 are arranged along the width direction of the web. In this example, there are two rows of the tension anchor bolts 2 along the width direction of the web, which is mainly suitable for the use of H-shaped steel beams with different widths. When the width dimension of the web becomes larger, three rows or more rows of the tension anchor bolts 2 can be selected.

[0023] Elastic stretchable metal hooks 3 are provided at the edge positions of the two flange plates of the steel beam body 1. A steel wire rope 4 is wound around the metal hooks 3 at the edge positions of the two flange plates on one side of the web. The steel wire rope 4 is wound in a staggered manner along the metal hooks 3 at the edge positions of the upper and lower flange plates, which is used to prevent the heat-insulating material in the web from moving outward and also plays an effect of strengthening the heat-insulating material.

[0024] Among them, the metal hook 3 includes a "C"-shaped clamping plate 301 fixed at the edge position of the flange plate of the steel beam body 1. A spring 302 is connected to the upper end of the clamping plate 301, and the other end of the spring 302 is connected to a hook 303. The clamping plate 301 can be fixed at the edge position of the flange plate of the steel beam body 1 by bolts or welding. The hook 303 and the clamping plate 301 are connected by the spring 302, which is used to make the steel wire rope 4 be in a long-term tension state and avoid the loosening of the heat-insulating material.

[0025] In this example, the hook 303 is made of stainless steel.

[0026] Specifically, wire meshes 5 are installed on both sides of the steel beam body 1 and outside the steel wire ropes 4. Both sides of the wire meshes 5 extend to the middle positions of the flanges of the steel beam body 1, and pressing strips 6 for pressing and fixing the wire meshes 5 are installed on the surface positions of the flanges of the steel beam body 1. Among them, the pressing strips 6 are made of stainless steel and are welded to the surface of the flanges of the steel beam body 1. The wire meshes 5 are used to further reinforce the thermal insulation material to prevent the thermal insulation material from detaching from the web of the steel beam body 1 after cracking, and the pressing strips 6 are used to reinforce the wire meshes 5.

[0027] This H-shaped steel beam thermal insulation fixing structure is mainly used to reinforce the thermal insulation material installed in the web of the steel beam to prevent the problems of detachment and shedding of the thermal insulation material due to cracking or long-term use. During specific use, the tie anchor bolts 2 can penetrate into the thermal insulation material, and the barbs 203 on the tie anchor bolts 2 can be used to reinforce the thermal insulation material. In addition, the steel wire ropes 4 and the wire meshes 5 are sequentially arranged on the periphery of the steel beam body 1, which can further reinforce the thermal insulation material and prevent the thermal insulation material from detaching.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
