Description

Technical Field

[0001] The utility model relates to the technical field of explosion relief of industrial building steel structures, and more specifically, to an explosion relief roof of a steel structure. Background Art

[0002] Explosion-proof roof is a lightweight pressure-relief roof commonly used in industrial and civil factory boiler rooms and hazardous goods warehouses. The explosion-proof roof mainly achieves explosion-proofing under the designed pressure through explosion-proof bolts and traction ropes. When an explosion occurs, the explosion-proof bolts fall off, causing the roof rock wool sandwich color steel plate to fall off successfully, while the traction rope pulls the explosion-proof plate, which will not cause secondary damage. The surface of the explosion-proof wall is normal without any signs of damage. After the explosion is handled, you only need to replace the explosion-proof fasteners on the explosion-proof roof and re-install it before it can continue to be used normally.

[0003] After searching, it was found that the Chinese patent with authorization announcement number CN217896929U discloses a steel structure explosion-proof roof structure. The structure adopts structural optimization and clear and reliable force transmission path, which changes the deformation mechanism of the explosion-proof process, is more conducive to protecting the explosion-proof plate, and is conducive to the rapid resumption of use of the steel structure after explosion-proofing.

[0004] However, at present, the explosion-proof roof traction rope is usually connected to the steel structure purlin on one side and the explosion-proof roof panel on the other side. In industrial plants with Class A fire hazard, since there are many purlin ceiling equipment and pipelines, the explosion-proof roof purlins are mostly made of square steel pipes that are easy to construct. The traditional traction rope fixing method is not only difficult to construct but also costly.

[0005] In view of this, the utility model proposes a steel structure explosion-proof roof, which forms a new traction rope fixing method by improving and optimizing the traction rope fixing method, which not only reduces the construction difficulty and improves the construction efficiency, but also ensures the construction quality. It has good economic benefits and social reputation, and is promoted for use in similar projects. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a steel structure explosion-proof roof to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel structure explosion-proof roof, comprising an explosion-proof plate, a steel purlin, an explosion-proof bolt device, a traction rope and a bolt assembly, wherein the steel purlin is installed at the bottom of the explosion-proof plate through the explosion-proof bolt device, and both ends of the traction rope are installed at the bottom of the explosion-proof plate through the bolt assembly.

[0008] It can be seen that the above structure achieves rapid pressure release under high pressure conditions through the organic combination of explosion relief plates, explosion relief bolt devices, traction ropes and bolt assemblies, while ensuring the comfort and safety of the building in daily use.

[0009] In order to achieve the connection between the steel purlin and the explosion-proof plate, and at the same time, the explosion-proof screw falls off to drive the roof rock wool sandwich color steel plate to fall off successfully, preferably, the explosion-proof bolt device includes an explosion-proof screw, the surface of the explosion-proof plate is penetrated with a through hole, and the interior of the through hole is filled with a waterproof gasket, the bottom end of the explosion-proof screw penetrates the waterproof gasket and the explosion-proof plate in sequence and extends to the interior of the steel purlin, and an aluminum alloy gasket is provided at the connection between the explosion-proof screw and the explosion-proof plate, and the cross-section of the aluminum alloy gasket is arc-shaped.

[0010] In order to ensure that the explosion-proof plate is subjected to uniform and symmetrical force during the explosion-proofing process and reduce the degree of damage to the explosion-proof plate, it is beneficial to quickly resume the use of the steel structure explosion-proofing roof after explosion-proofing, reduce the construction difficulty, improve the construction efficiency, and ensure the construction quality. Preferably, the bolt assembly includes two connecting screws, the two connecting screws are threadedly installed on the surface of the explosion-proof plate, and are equidistantly located on both sides of the steel purlin, the outside of the connecting screws are provided with metal gaskets at the top and bottom of the explosion-proof plate, the external threads of the connecting screws are installed with two locking nuts, both ends of the traction rope are connected with connecting rings, and the two ends of the traction rope are installed on the outside of the corresponding connecting screws through the connecting rings and are located between the two locking nuts, the traction rope bypasses the steel purlin and is located at the bottom of the steel purlin.

[0011] In order to meet the requirements of fire resistance, thermal insulation and explosion relief, preferably, the explosion relief panel is composed of a double-sided color steel plate and a glass wool core, wherein the glass wool core is inside the double-sided color steel plate.

[0012] Technical effects and advantages of the utility model:

[0013] 1. By connecting the traction rope with a bolt assembly, compared with the traditional explosion-proof plate and traction rope fixing method which usually involves drilling or opening holes in the purlins, which not only increases the construction difficulty, but also may damage the structural integrity of the purlins, especially on the square steel tube purlins, the setting of this structure avoids direct drilling and opening of these purlins, thereby solving the problem of incompatibility with the square steel tube purlins and improving the flexibility and applicability of construction;

[0014] 2. By adopting a new construction method, the traction rope and explosion relief plate do not need to drill or open holes on the square steel tube purlins, thereby reducing the risk of rust and potential structural weaknesses caused by drilling. This not only improves the overall safety of the structure, but also reduces long-term maintenance costs because it reduces the possibility of rust and other damages related to openings;

[0015] 3. The new structural method of the utility model has a fast construction speed and low material cost, which not only shortens the construction period, but also reduces the overall construction cost. At the same time, since unnecessary drilling and opening are avoided, the roof maintains a simple and beautiful appearance, and the design of the explosion-proof force transmission path is more reliable. During the explosion-proof process, the explosion-proof plate is subjected to uniform and symmetrical force, which helps to reduce the degree of damage to the explosion-proof plate, thereby facilitating the rapid resumption of use of the steel structure explosion-proof roof after explosion-proofing, ensuring the continuous operation and safety of the building.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-4 A steel structure explosion-proof roof is shown, comprising an explosion-proof plate 1, a steel purlin 2, an explosion-proof bolt device 3, a traction rope 4 and a bolt assembly 5. The steel purlin 2 is installed at the bottom of the explosion-proof plate 1 through the explosion-proof bolt device 3, and both ends of the traction rope 4 are installed at the bottom of the explosion-proof plate 1 through the bolt assembly 5.

[0023] Specifically, in this structure, the steel structure explosion-proof roof is composed of an explosion-proof plate 1, a steel purlin 2, an explosion-proof bolt device 3, a traction noose 4 and a bolt assembly 5, wherein the steel purlin 2 is installed at the bottom of the explosion-proof plate 1 through the explosion-proof bolt device 3 to achieve the connection between the steel purlin 2 and the explosion-proof plate 1, and both ends of the traction noose 4 are installed at the bottom of the explosion-proof plate 1 through the bolt assembly 5 to achieve the connection between the two ends of the traction noose 4;

[0024] The use of this new type of connection method of traction rope 4 has fast construction speed and low material cost. The roof steel purlin 2 does not need to be perforated with large holes, which greatly reduces the risk of rusting of the steel purlin 2, ensures that the structure is simple and beautiful, and the explosion-proof force transmission path is reliable. During the explosion-proof process, the explosion-proof plate 1 is subjected to uniform and symmetrical force, which reduces the degree of damage to the explosion-proof plate 1, thereby facilitating the rapid restoration of the steel structure explosion-proof roof after explosion-proofing.

[0025] The following is a detailed description of the above structure:

[0026] In a specific embodiment, as shown in the attached Figure 1 , 3 As shown, the explosion-proof bolt device 3 includes an explosion-proof screw 300, a through hole is opened on the surface of the explosion-proof plate 1, and the interior of the through hole is filled with a waterproof gasket 301, the bottom end of the explosion-proof screw 300 penetrates the waterproof gasket 301 and the explosion-proof plate 1 in sequence and extends to the interior of the steel purlin 2, and an aluminum alloy gasket 302 is provided at the connection between the explosion-proof screw 300 and the explosion-proof plate 1, and the cross-section of the aluminum alloy gasket 302 is arc-shaped.

[0027] Specifically, in this structure, the steel purlin 2 is connected to the explosion relief plate 1 through the explosion relief bolt device 3. The explosion relief screw 300 is a key part of connection and support. It passes through the explosion relief plate 1 and is fixed to the steel purlin 2 to maintain the stability of the structure. The through hole is opened on the surface of the explosion relief plate 1, and the interior is filled with a waterproof gasket 301, which not only ensures the sealing of the structure, but also prevents moisture and air from entering. The aluminum alloy gasket 302 is placed at the connection between the explosion relief screw 300 and the explosion relief plate 1, and its arc-shaped cross section helps to disperse the pressure and increase the contact area, thereby improving the stability and durability of the overall structure.

[0028] When the pressure inside the facility exceeds the designed safety limit, the explosion relief bolt device 3 will automatically start. After sensing the overpressure, the internal spring mechanism or the preset pressure rod will quickly push the sealing disk to break or disengage the explosion relief screw 300, thereby opening the pressure relief channel. Under the action of pressure, the explosion relief plate 1 will quickly open through the physical disconnection mechanism of the explosion relief screw 300, thereby quickly releasing the overpressure and avoiding a wider range of structural damage.

[0029] In a specific embodiment, as shown in the attached Figure 1 , 2As shown in , 4, the bolt assembly 5 includes two connecting screws 500, the two connecting screws 500 are threadedly installed on the surface of the explosion-proof plate 1, and are equidistantly located on both sides of the steel purlin 2, the outside of the connecting screws 500 is located at the top and bottom of the explosion-proof plate 1. Metal gaskets 501 are provided, and two locking nuts 502 are installed on the external threads of the connecting screws 500. Both ends of the traction rope 4 are connected with connecting rings 6, and the two ends of the traction rope 4 are installed on the outside of the corresponding connecting screws 500 through the connecting rings 6 and are located between the two locking nuts 502. The traction rope 4 bypasses the steel purlin 2 and is located at the bottom of the steel purlin 2.

[0030] Specifically, in this structure, the bolt assembly 5 is used to connect the two ends of the traction rope 4, and the connecting rings 6 at the two ends of the traction rope 4 are sleeved on the outside of the connecting screw 500, and the connecting rings 6 at the two ends of the traction rope 4 are locked by two locking nuts 502. At this time, the traction rope 4 bypasses the steel purlin 2 to connect the steel purlin 2;

[0031] Compared with the traditional connection method of the traction rope 4, the problem of special customization of bolts for square steel tube purlins, high cost and great construction difficulty is solved. The new connection method of the traction rope 4 has fast construction speed and low material cost. The roof steel purlin 2 does not need large-eye perforation, which greatly reduces the risk of rusting of the steel purlin 2, ensures a simple and beautiful structure, a reliable explosion-proof force transmission path, and uniform and symmetrical force on the explosion-proof plate 1 during the explosion-proof process, which reduces the degree of damage to the explosion-proof plate 1, thereby facilitating the rapid restoration of the steel structure explosion-proof roof after explosion-proofing.

[0032] In a specific embodiment, as shown in the attached Figure 1 As shown, the explosion venting plate 1 is composed of a double-sided color steel plate and a glass wool core, wherein the glass wool core is located inside the double-sided color steel plate.

[0033] Specifically, in this structure, the explosion-proof panel 1 structure composed of double-sided color steel plates and glass wool sandwich can provide better fire resistance, thermal insulation effect, structural strength and air tightness, while meeting the requirements of explosion-proof function and ensuring the safety, comfort and economy of the building.

[0034] Working principle of this utility model:

[0035] The utility model provides a steel structure explosion-proof roof. First, the explosion-proof panel 1 is composed of double-sided color steel plates and glass wool sandwich. This structure not only ensures good fire resistance and thermal insulation effects, but also enhances the overall structural strength and air tightness. Under normal circumstances, the explosion-proof panel 1 plays a role in protecting the interior of the building from the influence of the external environment, including waterproofing, fire prevention and thermal insulation. In the event of high pressure such as an explosion, the explosion-proof panel 1 is designed to be able to open quickly to release pressure, thereby protecting the structure from damage;

[0036] The explosion-proof bolt device 3 connects the steel purlin 2 with the explosion-proof plate 1 through the explosion-proof screw 300. The explosion-proof screw 300 passes through the through hole provided with the waterproof gasket 301 and enters the explosion-proof plate 1, and is finally fixed to the inside of the steel purlin 2. When the internal pressure exceeds the set value, the explosion-proof bolt device 3 will start, so that the explosion-proof screw 300 will be disengaged or broken, so that the explosion-proof plate 1 can be opened, the pressure is quickly released, and the structural safety is protected;

[0037] The traction rope 4 is installed at the bottom of the explosion venting plate 1 through the bolt assembly 5, and its two ends are fixed to the connecting screw 500 through the connecting ring 6 and the locking nut 502. This design allows the traction rope 4 to bypass the steel purlin 2 and be located at the bottom thereof, providing a simple, beautiful and effective connection method. This connection method has a fast construction speed and low cost, and at the same time reduces the risk of drilling and rusting of the steel purlin 2, ensuring the beauty and durability of the structure;

[0038] The entire explosion-proof roof of the utility model ensures that the explosion-proof plate 1 is subjected to uniform and symmetrical force during the explosion-proof process, which helps to reduce the degree of damage to the explosion-proof plate 1. Through the optimized layout of the traction rope 4 and the setting of the explosion-proof bolt device 3, a reliable explosion-proof force transmission path is achieved, so that the pressure can be effectively dispersed during the explosion-proof process, thereby protecting the stability and safety of the entire roof structure.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
