Description

Technical Field

[0001] This invention belongs to the field of fire-resistant steel structure technology for buildings, and specifically relates to a green building energy-saving fire-resistant steel structure. Background Technology

[0002] With the development of the global economy, its negative effects have become increasingly apparent, namely the growing severity of energy shortages and environmental pollution. Therefore, green building and energy conservation and emission reduction are receiving increasing attention. Steel structures, as a building structure form with high strength, lightweight, and good seismic performance, have been widely used in various buildings. However, traditional steel structure buildings suffer from poor fire resistance, poor thermal insulation, and high energy consumption, failing to meet the requirements of green buildings. Therefore, developing a green, energy-saving, and fire-resistant steel structure has become a current research hotspot. For example, Chinese patent publication number "CN218479341U" discloses a green, energy-saving, and fire-resistant steel structure. This structure, through the combined use of a steel structure base plate, corrosion-resistant coating, fire-retardant coating, springs, movable clamps, fixed clamps, two bolts, two nuts, buffer plate, sound-absorbing groove, limiting plate, one nut, movable sleeve, adjusting frame, and one bolt, possesses the advantages of good fire resistance and adaptability to different installation conditions. It solves the problem of the poor fire resistance of existing steel structures, which are easily scorched in the event of a fire, affecting their aesthetics and durability. Furthermore, it addresses the inconvenience of installation according to actual conditions. The problem of poor applicability is another example. For instance, Chinese patent publication number "CN218091386U" discloses a green building energy-saving fireproof steel structure. This steel structure includes a fireproof insulation board, with symmetrical fireproof steel components on both the front and rear sides of the fireproof insulation board. Each group of fireproof steel components consists of a steel structure and restraint components. The steel structure includes a steel mesh, which is located on the front side of the fireproof insulation board. Multiple equidistantly distributed inserts are fixed to the rear side of the steel mesh. Multiple openings matching the inserts are provided on the sidewalls of the fireproof insulation board. The insertion holes and multiple insertion rods are all set with an upward tilt angle. The multiple symmetrical insertion holes on the front and rear sides of the fireproof insulation board are not interconnected. The above device only has a fireproof structure, and the insulation performance of the device is still poor. Although an insulation board is installed, outdoor air will directly enter the building when the building is ventilated. In summer, the high temperature of outdoor air will cause the temperature inside the building to rise, thereby increasing the energy consumption of the cooling equipment inside the building. In winter, the low temperature of outdoor air will cause the temperature inside the building to drop, thereby increasing the energy consumption of the heating equipment inside the building and increasing carbon emissions. Summary of the Invention

[0003] The purpose of this invention is to provide a green building energy-saving and fireproof steel structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a green building energy-saving and fireproof steel structure, comprising: N steel structure base components, N≥2; A heat exchanger includes a heat exchanger body, which is installed inside the heat exchanger. An outdoor air inlet pipe, an outdoor air outlet pipe, an indoor air outlet pipe, and an indoor air inlet pipe are fixedly connected to the heat exchanger body. The outdoor air inlet pipe and the indoor air inlet pipe are symmetrically distributed on both sides of the heat exchanger body. The outdoor air outlet pipe is on the same side as the outdoor air inlet pipe, and the indoor air outlet pipe is on the same side as the indoor air inlet pipe. The outdoor air outlet pipe is connected to the indoor air inlet pipe, and the outdoor air inlet pipe is connected to the indoor air outlet pipe.

[0005] Preferably, the top and bottom of the steel structure base are respectively fixedly connected with a detachable first connector and a second connector, and the first connector and the second connector are connected or separated to connect or separate two adjacent steel structure bases.

[0006] Preferably, an indoor air intake fan is installed inside the indoor air intake pipe; An outdoor air intake fan is installed inside the outdoor air intake pipe.

[0007] Preferably, a first filter screen is installed inside the indoor air intake pipe, and a second filter screen is installed inside the outdoor air intake fan. The first filter screen is located on the air intake side of the indoor air intake fan, and the second filter screen is located on the air intake side of the outdoor air intake fan.

[0008] Preferably, the first connector includes a top frame, the top of which has two symmetrically formed top grooves, a connecting plate is fixedly connected inside the top grooves, and a first connecting hole is formed on both the connecting plate and the top frame, and a connecting screw is screwed into the first connecting hole. The second connector includes a base frame, the bottom of which has a bottom groove that matches the top groove, and the base frame has a second connecting hole that matches the connecting screw.

[0009] Preferably, the steel structure base includes a mounting steel frame; The mounting steel frame is recessed on the side facing the heat exchanger body to form a vacuum cavity that accommodates the heat exchanger body.

[0010] Preferably, the vacuum chamber has two side plates symmetrically fixedly connected inside, and an insulation plate is also installed inside the vacuum chamber. The heat exchanger body is located between the side plates and the insulation plate. The insulation plate and the side plates are screwed together with positioning screws, and through holes are opened on the insulation plate and the mounting steel frame.

[0011] Preferably, a spraying component for spraying water is installed on the side of the insulation board away from the mounting steel frame.

[0012] Preferably, the spray component includes a connecting pipe connected to a water supply pipe, and a diverter plate is fixedly connected to the side of the connecting pipe away from the insulation board. A glass ball is disposed between the diverter plate and the connecting pipe.

[0013] Preferably, a shielding component is installed on the side of the mounting steel frame away from the insulation board. The shielding component includes a motor, and the output end of the motor facing the mounting steel frame is connected to a connecting frame. Two baffles are symmetrically fixedly connected to the connecting frame facing the mounting steel frame, and a sealing gasket is adhered to the side of the baffles facing the mounting steel frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up a heat exchanger, when the building needs to be ventilated, the heat exchanger works to guide outdoor air into the building and guide indoor air to the outside. When indoor air and outdoor air flow inside the heat exchanger, the heat exchanger exchanges heat between the indoor air and outdoor air, thereby reducing heat loss when the building is ventilated. In summer, the high temperature of outdoor air will not cause the temperature inside the building to rise, thereby reducing the energy consumption of the cooling equipment inside the building. In winter, the low temperature of outdoor air will not cause the temperature inside the building to drop, thereby reducing the energy consumption of the heating equipment inside the building and reducing carbon emissions.

[0015] (2) When the present invention exchanges heat between indoor and outdoor air through the heat exchanger body, by setting a first filter, a second filter, an indoor air intake fan and an outdoor air intake fan, the efficiency of gas passing through the heat exchanger body is accelerated, so that the device can assist the building in ventilation more quickly, thereby improving the building ventilation efficiency.

[0016] (3) By setting up a shielding component, when the building does not need ventilation, the connecting frame is driven by a motor to rotate, which causes the connecting frame to rotate and the baffle to block the outdoor air inlet pipe and the outdoor air outlet pipe, thereby preventing the outdoor gas and indoor gas from exchanging heat, thus improving the building's thermal insulation efficiency.

[0017] (4) By setting up a vacuum chamber, when the device stops exchanging air, the vacuum chamber isolates the heat between the indoor and outdoor areas, preventing heat exchange between the indoor and outdoor areas, thereby reducing the loss of indoor heat or preventing outdoor heat from being conducted into the indoor area, and further improving the thermal insulation efficiency of the building.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-13 As shown, the present invention provides the following technical solution: A green building energy-saving and fireproof steel structure, in order to facilitate the construction of steel structure buildings, the waterproof steel structure includes N steel structure base members 1, N≥2; In addition, after the steel structure building is constructed using the steel structure base 1, in order to reduce heat loss inside the building during winter ventilation or to prevent outdoor heat from being conducted into the building during summer ventilation, the waterproof steel structure also includes a heat exchanger 6. The heat exchanger 6 includes a heat exchanger body 69, which is installed inside the heat exchanger 6. An outdoor air inlet pipe 64, an outdoor air outlet pipe 67, an indoor air outlet pipe 68, and an indoor air inlet pipe 63 are fixedly connected to the heat exchanger body 69. The outdoor air inlet pipe 64 and the indoor air inlet pipe 63 are symmetrically distributed on both sides of the heat exchanger body 69. The outdoor air outlet pipe 67 is on the same side as the outdoor air inlet pipe 64, and the indoor air outlet pipe 68 is on the same side as the indoor air inlet pipe 63. The outdoor air outlet pipe 67 is connected to the indoor air inlet pipe 63, and the outdoor air inlet pipe 64 is connected to the indoor air outlet pipe 68.

[0021] Through the above technical solution, a steel structure building is constructed using a steel structure base 1. After the steel structure building is constructed, the heat exchanger 6 is installed inside the steel structure base 1, so that the heat exchanger body 69 is located inside the steel structure base 1. This allows one end of the indoor air outlet pipe 68 and the indoor air inlet pipe 63 to be inside, while one end of the outdoor air outlet pipe 67 and the outdoor air inlet pipe 64 is outside. When people need to ventilate the building, the indoor air is guided through the indoor air inlet pipe 63, transporting the gas to the heat exchanger body 69. Finally, the indoor air is discharged through the outdoor air outlet pipe 67, and the outdoor air is guided through the outdoor air inlet pipe 64, transporting the gas to the heat exchanger body 69. Finally, the outdoor air is transported back inside through the indoor air outlet pipe 68. When the outdoor and indoor air flow within the heat exchanger body 69, the heat exchanger body 69... 9. Assists in heat exchange between outdoor and indoor gases, thereby reducing the temperature difference between them. For example, if the indoor environment is low-temperature and the outdoor environment is high-temperature, when the high-temperature outdoor gas enters the heat exchanger body 69, the low-temperature indoor gas will also enter the heat exchanger body 69. Through the heat exchanger body 69, the low-temperature indoor gas and the high-temperature outdoor gas exchange heat, lowering the temperature of the outdoor gas delivered to the room, thus reducing the energy consumption of the refrigeration equipment. Alternatively, if the building interior is a high-temperature environment and the outdoor environment is low-temperature, when the low-temperature outdoor gas enters the heat exchanger body 69, the high-temperature indoor gas will also enter the heat exchanger body 69. Through the heat exchanger body 69, the high-temperature indoor gas and the low-temperature outdoor gas exchange heat, raising the temperature of the outdoor gas delivered to the room, thus reducing the energy consumption of the heating equipment.

[0022] Furthermore, in this invention, regarding how the steel structure base component 1 is connected, as follows: Figures 1-6 As shown, The top and bottom of the steel structure base 1 are respectively fixedly connected to a detachable first connector 2 and a second connector 5, and the first connector 2 and the second connector 5 are connected or separated to connect or separate two adjacent steel structure bases 1.

[0023] In this embodiment, when it is necessary to connect adjacent steel structure bases 1, the steel structure base 1 is placed on the first connector 2 on another steel structure base 1, and connected to the second connector 5 through the first connector 2, thereby connecting the adjacent steel structure bases 1 and fixing the two adjacent steel structure bases 1. By following the above steps, the device can adjust the connection or disassembly of adjacent steel structure bases 1 according to personnel needs.

[0024] Furthermore, when gas needs to be guided, in order to accelerate gas flow, such as... Figures 7-10 As shown, an indoor air intake fan 62 is installed inside the indoor air intake pipe 63; An outdoor air intake fan 65 is installed inside the outdoor air intake pipe 64.

[0025] In this embodiment, when the device guides the gas flow through the indoor air inlet pipe 63 and the outdoor air inlet pipe 64, the outdoor air inlet fan 65 inside the outdoor air inlet pipe 64 works, thereby guiding the indoor and outdoor gas flow more efficiently and improving the heat exchange efficiency of the device.

[0026] Furthermore, when the gas flows within the heat exchanger body 69, to prevent external dust from entering the interior of the heat exchanger body 69, such as... Figures 7-10 As shown, a first filter 61 is installed inside the indoor air intake pipe 63, and a second filter 66 is installed inside the outdoor air intake fan 65. The first filter 61 is located on the air intake side of the indoor air intake fan 62, and the second filter 66 is located on the air intake side of the outdoor air intake fan 65.

[0027] In this embodiment, when the device guides the gas flow through the indoor air inlet pipe 63 and the outdoor air inlet pipe 64, the outdoor air inlet fan 65 inside the outdoor air inlet pipe 64 works, thereby guiding the indoor and outdoor gas flow more efficiently. Furthermore, during the gas flow, the first filter screen 61 and the second filter screen 66 work to filter the outdoor and indoor gas entering the heat exchanger body 69, preventing dust from entering the interior of the heat exchanger body 69.

[0028] Specifically, in one embodiment, regarding the first connector 2 and the second connector 5 described above:

[0029] In this embodiment, when it is necessary to connect two adjacent steel structure bases 1, the steel structure base 1 is taken out and connected to the top frame 22 on another steel structure base 1 through the base frame 53. The top groove 21, the top frame 22 and the base frame 53 are engaged, and then the connecting screw 25 is connected to the top groove 21 and the first connecting hole 23 to connect the two adjacent steel structure bases 1.

[0030] When personnel need to install the heat exchanger body 69, in order to facilitate the installation of the heat exchanger body 69, such as... Figures 1-10 As shown, the steel structure base 1 includes a mounting steel frame 16; The mounting steel frame 16 is recessed on the side facing the heat exchanger body 69 to form a vacuum chamber 15 that accommodates the heat exchanger body 69.

[0031] In this embodiment, the heat exchanger body 69 is housed in the vacuum chamber 15 on the side of the steel frame 16.

[0032] Furthermore, when the heat exchanger body 69 needs to be replaced, in order to facilitate the replacement of the heat exchanger body 69, such as... Figures 1-3 , Figures 6-10 As shown, two side plates 14 are symmetrically fixedly connected inside the vacuum chamber 15, and an insulation plate 13 is also installed inside the vacuum chamber 15. The heat exchanger body 69 is located between the side plates 14 and the insulation plate 13. The insulation plate 13 and the side plates 14 are screwed together with a positioning screw 12, and through holes 11 are opened on the insulation plate 13 and the mounting steel frame 16.

[0033] In this embodiment, the heat exchanger body 69 is housed in the vacuum chamber 15 on one side of the steel frame 16. After the heat exchanger body 69 is placed, the insulation plate 13 is placed on one side of the vacuum chamber 15 so that the insulation plate 13 is in contact with the side plate 14. The positioning screw 12 is inserted between the side plate 14 and the insulation plate 13 and screwed in to fix the insulation plate 13. The insulation plate 13 continuously contacts the heat exchanger body 69. When it is necessary to disassemble the heat exchanger body 69, simply unscrew the positioning screw 12. After the device is installed, the air inside the vacuum chamber 15 is extracted by a negative pressure device (not shown in the figure) so that the vacuum chamber 15 reaches a relative vacuum state.

[0034] In addition, in order to facilitate timely fire extinguishing, a spraying component 3 for spraying water is installed on the side of the insulation board 13 away from the installation steel frame 16. The water is sprayed through the spraying component 3 to extinguish the fire.

[0035] Specifically, in one embodiment, regarding the above-mentioned spray element 3: like Figure 1 , Figure 4 , Figure 7As shown, the spray component 3 includes a connecting pipe 31 connected to the water supply pipe. A diverter plate 32 is fixedly connected to the side of the connecting pipe 31 away from the insulation board 13. A glass ball 33 is provided between the diverter plate 32 and the connecting pipe 31.

[0036] In this embodiment, when a fire occurs inside the building and the internal temperature rises, the glass ball 33 automatically breaks, exposing one end of the connecting pipe 31, which then sprays water. When the connecting pipe 31 sprays water, the water is diverted by the diversion plate 32, allowing the water to be sprayed over a large area and onto the building to extinguish the fire inside.

[0037] Furthermore, when ventilation is not required inside the building, such as Figures 1-3 , Figures 6-10 As shown, a shielding component 4 is installed on the side of the mounting steel frame 16 away from the insulation board 13. The shielding component 4 includes a motor 41, and the output end of the motor 41 facing the side of the mounting steel frame 16 is connected to a connecting frame 42. Two baffles 43 are symmetrically fixedly connected to the side of the connecting frame 42 facing the side of the mounting steel frame 16. A sealing gasket 44 is adhered to the side of the baffles 43 facing the side of the mounting steel frame 16.

[0038] In this embodiment, when ventilation is not required in the building, the motor 41 operates, causing the connecting frame 42 to rotate. The connecting frame 42 then rotates the baffle 43, which in turn blocks the outdoor air inlet pipe 64 and the outdoor air outlet pipe 67, thus preventing the exchange of outdoor air with the indoor air and isolating the indoor and outdoor environments. This improves the building's internal insulation efficiency. Furthermore, when the baffle 43 blocks the outdoor air inlet pipe 64 and the outdoor air outlet pipe 67, the sealing gasket 44 further enhances the airtightness of the baffle 43 in blocking these pipes. When ventilation is required, the motor 41 operates, causing the connecting frame 42 to rotate. The connecting frame 42 then rotates the baffle 43, preventing the baffle 43 from blocking the outdoor air inlet pipe 64 and the outdoor air outlet pipe 67, thus allowing the exchange of outdoor air with the indoor air.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
