Description

Technical Field

[0001] The present invention relates to the technical field of steel structures, and specifically to a prefabricated steel structure that can reduce energy consumption. Background Art

[0002] Steel structures are one of the common types of building structures. Due to the advantages of high strength, light self-weight, good overall rigidity, and strong deformation ability of steel structures themselves, steel structures are widely used in the construction field. The most common connection methods for steel structures during use are welding, riveting, and bolt connection, etc.

[0003] For example, a fireproof and heat-insulating safety steel structure with the publication number CN212772929U, which includes an outer steel pipe and an inner steel pipe. The inner steel pipe is arranged inside the outer steel pipe. One or more material discharge holes are provided on the outer wall surface of the outer steel pipe. Material discharge ports are provided on the outer wall surface of the inner steel pipe at the upper ends of the material discharge holes. More than one partition is installed inside the inner steel pipe. The inside of the inner steel pipe is divided into more than one storage cavity by more than one partition. Heat-insulating materials are provided inside the storage cavities. Support blocks are provided on the bottom surface inside the outer steel pipe, and springs are installed on the top surface of the inner steel pipe.

[0004] Among the above-mentioned prior arts, there are also the following technical defects: In order to improve its own heat-insulating effect and reduce energy consumption when the above-mentioned steel structure is in use, sand is set as a heat-insulating material inside the steel structure. However, when sand is stored inside the steel structure, the sand is in a static state and does not have any fluidity. As a result, the sand on the side close to the steel structure will be heated, while the sand far from the steel structure and located in the middle part of the tank has a lower heat absorption effect than the sand on the outside. Furthermore, the overall heat absorption effect of the sand is reduced, and the overall heat-insulating effect of the sand is reduced.

[0005] Therefore, we propose a prefabricated steel structure that can reduce energy consumption to solve the problems raised above. Summary of the Invention

[0019] Preferably, the number of side openings on the side of the containing block is equal to the diameter of the leakage hole on the side of the steel column, and the containing block can slide on the fixing rod.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0045] See also Figures 1-8 , the present invention provides the following two embodiments:

[0046] Embodiment 1:

[0047] In order to improve the thermal insulation effect and reduce energy consumption of the existing steel structure during use, sand is set inside the steel structure as a thermal insulation material. However, when the sand is stored inside the steel structure, the sand is in a static state and does not have any fluidity, which causes the sand close to the steel structure to be heated, while the sand in the middle of the trough far away from the steel structure absorbs less heat than the sand on the outside, thereby reducing the overall heat absorption effect of the sand and reducing the overall thermal insulation effect of the sand. In order to solve this technical problem, this embodiment discloses the following technical contents, such as Figures 3-8 As shown;

[0048] The leakage hole 7 is opened on the side of the steel column 1. A containing block 8 is installed inside the steel column 1, and a side opening 9 is opened on the side of the containing block 8. A hot melt block 10 is installed on the left and right sides of the lower end of the containing block 8, and two limit plates 11 are arranged inside the containing block 8. In the absence of fire, the hot melt block 10 will not be ignited or softened by the heat generated from the outside. The number of side openings 9 on the side of the containing block 8 is equal to the number of leakage holes 7 on the side of the steel column 1, and the side openings 9 and the leakage holes 7 are staggered up and down in the initial state. The number of side openings 9 on the side of the containing block 8 is equal to the diameter of the leakage hole 7 on the side of the steel column 1, and the containing block 8 can slide on the fixing rod 12. The fixing rod 12 is fixed inside the steel column 1, and the fixing rod 12 is inserted into the inside of the containing block 8. The fixing rod 12 is sleeved with a sand guide block 13, and a propulsion airbag 14 is fixedly connected to the bottom of the sand guide block 13, and the top of the sand guide block 13 is filled with gravel; the active airbag 15 is sleeved in the middle of the fixing rod 12, and the active airbag 15 is connected to the propulsion airbag 14 through a connecting pipe 16; the resistance rod 17 is located in the middle of the containing block 8, and the resistance rod 17 is connected to the inside of the containing block 8 through a reset spring 18, and the lower end of the resistance rod 17 is fixedly connected to a guide airbag 14. The airbag 19 guides the lower end of the airbag 19 to be fixedly connected with a heat dissipation column 20, and the heat dissipation column 20 extends into the water tank 21. In the initial state, the heat dissipation column 20 does not contact the water source inside the water tank 21. A semiconductor refrigeration plate is installed inside the water tank 21. The heat dissipation column 20 is made of a heat-conducting material; the vertical rod 22 is located on the upper side of the abutment rod 17. The vertical rod 22 is fixedly installed at the lower end of the horizontal pressing block 23, and a positioning block 24 is installed on the horizontal pressing block 23. The positioning block 24 is fixed inside the containing block 8, and the positioning block 24 is connected to the horizontal pressing block 23 through a built-in spring 25. The inner wall of the middle part of the sand guide block 13 and the outer wall of the fixed rod 12 fit each other, and the sand guide block 13 can slide vertically on the fixed rod 12. The sand guide block 13 is flush with the leakage hole 7 on the side of the steel column 1, and the upper surface of the sand guide block 13 is inclined toward the direction of the leakage hole 7. The guide airbag 19 is located between the abutment rod 17 and the heat dissipation column 20, and the interior of the guide airbag 19 is filled with heat expansion gas, and the abutment rod 17 forms an elastic telescopic structure through the return spring 18 and the containing block 8. The upper end of the abutment rod 17 and the lower end of the vertical rod 22 are both set as spherical structures, and the upper end of the abutment rod 17 and the lower end of the vertical rod 22 are in contact with each other. The inner wall of the horizontal pressing block 23 and the lower end outer wall of the positioning block 24 are in contact with each other, and the horizontal pressing block 23 forms an elastic telescopic structure through the built-in spring 25 and the positioning block 24.

[0049] The working principle of this embodiment is: when the steel structure is hot during the day, the gravel inside the containing block 8 can absorb the high temperature, and the heat absorption of the gravel can play a role in heat preservation. If a fire occurs, the hot melt block 10 inside the steel column 1 melts after absorbing heat. At this time, the containing block 8 moves downward without the support of the hot melt block 10. After the containing block 8 moves downward on the fixing rod 12, the side opening 9 on the side of the containing block 8 is aligned with the leakage hole 7 on the side of the steel column 1. At this time, the inclined surface on the upper end of the sand guide block 13 can be used to guide the gravel inside the containing block 8 out of the steel column 1. The overflowing gravel plays a role in extinguishing fire and preventing fire. However, under normal circumstances, when the temperature is high during the day, the guiding airbag 19 inside the steel column 1 expands after absorbing heat. After the guiding airbag 19 expands, it pushes the upper resistance rod 17 and the lower heat dissipation column 20 to move synchronously relative to each other. After the heat dissipation column 20 moves, its lower end contacts the water source inside the water tank 21. The water source inside the water tank 21 can cool the heat dissipation column 20, so that the heat dissipation column 20 is in a low temperature state. After the heat dissipation column 20 cools down, the low temperature is transferred to the guiding airbag 19 at the upper end. The guiding airbag 19 The airbag 19 contracts after cooling down. At this time, the contracted guide airbag 19 pulls the heat dissipation column 20 and the abutment rod 17 to reset. The heat dissipation column 20 is separated from the water source inside the water tank 21, thereby realizing the up and down reciprocating movement of the abutment rod 17. When the abutment rod 17 moves upward, it can squeeze and push the vertical rod 22, so that the vertical rod 22 drives the horizontal pressing block 23 to move toward the outside of the steel column 1. The movement of the horizontal pressing block 23 is used to squeeze the active airbag 15. After the active airbag 15 is compressed, the internal airflow enters the inside of the propulsion airbag 14 through the connecting pipe 16. When the abutment rod 17 After moving downward, the horizontal pressing block 23 is reset and rebounded under the action of the built-in spring 25, and the horizontal pressing block 23 stops squeezing the active airbag 15. The airflow inside the propulsion airbag 14 flows back to the inside of the active airbag 15 through the connecting pipe 16. The reciprocating expansion of the propulsion airbag 14 enables the upper sand guide block 13 to move up and down. The reciprocating movement of the sand guide block 13 can move the sand inside the containing block 8, thereby improving the fluidity of the sand inside the containing block 8 and preventing the sand from being stationary for a long time and reducing its overall heat absorption and heat preservation effect.
