Description

Technical Field

[0001] This utility model relates to the field of steel structure workshops, and in particular to a cross-braced, wind- and earthquake-resistant double-layer steel structure workshop. Background Technology

[0002] A wind- and earthquake-resistant double-layer steel structure factory building is an industrial building that combines the high strength and lightweight characteristics of steel structures with the additional advantages of a double-layer structure. This type of factory building is particularly suitable for areas with strong winds and frequent earthquakes, effectively resisting damage from natural disasters.

[0003] In practical applications of wind-resistant and earthquake-resistant double-layer steel structure factory buildings, despite the widespread use of steel structures in industrial plant construction due to their high strength, light weight, and spaciousness, slight swaying or shaking may occur under strong winds. This is because, although the design of steel structure factory buildings takes into account principles such as reducing the natural vibration period and ensuring structural stiffness and strength, swaying may still occur under extreme weather conditions, such as encountering winds stronger than expected. Such swaying is permissible under normal circumstances, but if the amplitude of the swaying is too large, it may threaten the structural safety of the factory building. Utility Model Content

[0004] The main purpose of this utility model is to provide a cross-braced, wind- and earthquake-resistant double-layer steel structure factory building, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cross-braced, wind- and earthquake-resistant double-layer steel structure factory building includes a triangular support frame, a lateral support frame, an arched support frame, and an upper support frame. The arched support frame is installed between two parallel lateral support frames. A triangular support frame is installed at the lower end of each lateral support frame. The triangular support frame and its extension column are installed on the factory floor or extend below the factory floor. The upper support frame is installed on the arched support frame.

[0007] The lower end of the arched support frame is equipped with a lower support, which, together with the upper support and the arched support frame, forms a double-layer steel structure roof to improve seismic performance. The lower support is spaced out to reduce the overall weight.

[0008] The lower support and the arched support frame are connected by a connecting seat, and the lower end of the connecting seat is provided with a connecting head. The lower end of the connecting head is connected to a connecting rod through a connecting flange. A universal ball is provided between the two connecting rods. The lower connecting rod is provided with a connecting screw hole. The lowest connecting rod is connected to a suspension rope and a counterweight to change the overall center of gravity and improve wind resistance.

[0009] In a preferred embodiment of this application, each of the triangular support frames is connected by a connecting strip, which enhances the robustness of the triangular support frames. The connecting strip has an "I" shaped cross-section and is fixed to the triangular support frames by bolts and anti-slip pads.

[0010] In a preferred embodiment of this application, the number of upper supports is twice the number of lower supports, the lower supports are fixed to the arched support frame by bolts and anti-slip pads, and the arched support frame and the lateral support frame are fixed together by bolts and anti-slip pads.

[0011] In a preferred embodiment of this application, the interior of the connecting seat is a hollow structure, and the side wall of the connecting seat is provided with holes that are adapted to the arched support frame and the lower support frame. Anti-slip rubber pads are provided at the connection between the connecting seat and the arched support frame and the lower support frame.

[0012] In a preferred embodiment of this application, the connector and the connector seat are designed as a single unit, and the lower end of the connector is provided with a connecting flange. The mating rod and the connecting flange are designed as a single unit, and the cross-section of the mating rod and the connecting flange is designed in a "T" shape.

[0013] In a preferred embodiment of this application, the universal ball is fixed to two docking rods by a rotating shaft and fasteners, and the docking screw hole at the lower end of the docking rod is an extension rod insertion hole, and the hole wall of the docking screw hole is provided with an insertion hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This structure significantly enhances the factory building's wind and earthquake resistance. Through the precise coordination of triangular support frames, lateral support frames, arched support frames, and upper and lower supports, a stable double-layer steel structure system is formed. This structure can effectively disperse and absorb external forces when facing natural disasters such as strong winds and earthquakes, thereby protecting the main structure of the factory building from damage.

[0016] The structure's design optimizes load distribution. The number of upper supports is twice that of lower supports, a design that better disperses the load on the upper layers. Meanwhile, the lower supports are secured to the arched support frame with bolts and anti-slip pads, ensuring the stability and reliability of load transfer. This optimized load distribution not only enhances the structure's load-bearing capacity but also helps extend the building's service life.

[0017] The design of the swaying wind-resistant mechanism allows the entire structure to adapt more flexibly to wind conditions. Through the coordination of connecting seats, connectors, docking rods, and omnidirectional balls, flexible connection and swaying of the structure are achieved. This design not only enhances the structure's wind resistance but also allows the factory building to maintain a relatively stable state under wind conditions, reducing the risk of structural damage due to excessive wind force.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 4 As shown, a cross-braced, wind- and earthquake-resistant double-layer steel structure factory building mainly includes a triangular support frame 1, lateral support frames 3, arched support frames 4, and an upper support frame 5. The triangular support frame 1 is installed at the lower end of each lateral support frame 3 and fixed to the factory floor or below ground level via its extension columns to ensure the stability of the overall structure. The lateral support frames 3 are installed parallel between two arched support frames 4, while the upper support frame 5 is located above the arched support frames 4, together forming a robust double-layer steel structure roof.

[0025] A lower support 6 is installed at the lower end of the arched support frame 4. This design not only enhances the seismic performance of the entire structure, but also effectively reduces the overall weight through the spaced arrangement of the lower support 6. The lower support 6, together with the upper support 5 and the arched support frame 4, forms a stable double-layer roof structure.

[0026] A connecting seat 7 is specially designed at the connection point between the lower support 6 and the arched support frame 4, with a connector 8 installed at its lower end. The connector 8 is connected to the connecting rod 9 via a connecting flange 11, and universal balls 10 are provided between the connecting rods 9 to provide a flexible connection method. The lower end of the connecting rod 9 is provided with a connecting screw hole 12, and the lowest connecting rod 9 is also connected to a suspension rope and a counterweight, which further improves the wind resistance of the entire structure by adjusting the center of gravity.

[0027] The triangular support frames 1 are connected to each other by connecting strips 2. The design of connecting strips 2 not only enhances the sturdiness of the triangular support frames 1, but also has an "I"-shaped cross section. It is fixed to the triangular support frames 1 by bolts and anti-slip pads, ensuring the reliability of the connection.

[0028] The number of upper-level supports 5 is twice that of lower-level supports 6. This design can better distribute the load on the upper level. Meanwhile, the lower-level supports 6 are fixed to the arched support frame 4 with bolts and anti-slip pads. The arched support frame 4 and the lateral support frame 3 are also fixed with bolts and anti-slip pads, ensuring the stability and safety of the entire structure.

[0029] The interior of the connecting seat 7 is hollow, and its side walls have openings that fit the arched support frame 4 and the lower support 6. Anti-slip rubber pads are provided at the connection points between the connecting seat 7 and the arched support frame 4 and the lower support 6 to enhance stability and ensure the connection is secure and safe.

[0030] The connector 8 and the connector 7 are designed as a single unit. The lower end of the connector 8 is provided with a connecting flange 11. The mating rod 9 and the connecting flange 11 are designed as a single unit. Its cross-section is "T" shaped. This design simplifies the structure, reduces the complexity of the connection parts, and ensures the strength and reliability of the connection.

[0031] The omnidirectional ball 10 is fixed to the two connecting rods 9 via a pivot and fasteners. The connecting screw hole 12 at the lower end of the connecting rod 9 serves as the insertion hole for the extension rod. The hole wall has an insertion hole into which a round rod is inserted. The round rod restricts the extension rod, improving its robustness. This design allows the entire structure to adapt more flexibly to wind and seismic forces, thereby effectively improving the wind and earthquake resistance of the entire factory building.

[0032] Install the triangular support frame 1 at the lower end of each lateral support frame 3. Secure the triangular support frame 1 to the factory floor or below ground level using extension columns to ensure the stability of the overall structure. Install the lateral support frames 3 parallel to each other between the two arched support frames 4. Install the upper support frame 5 above the arched support frames 4 to form a double-layer steel structure roof. Install the lower support frame 6 at the lower end of the arched support frames 4 to enhance the structure's seismic performance. The spaced lower support frames 6 effectively reduce the overall weight. Install a connecting seat 7 at the connection point between the lower support frame 6 and the arched support frame 4. Install a connector 8 at the lower end of the connecting seat 7.

[0033] Connector 8 is connected to connecting rod 9 via connecting flange 11. Universal ball joints 10 are provided between connecting rods 9 for flexible connection. Connecting bolt holes 12 are provided at the lower end of connecting rod 9. The lowest connecting rod 9 is connected to a suspension rope and counterweight, improving wind resistance by adjusting the center of gravity. Triangular support frames 1 are connected to each other via connecting strips 2. The design of connecting strips 2 enhances the stability of triangular support frames 1; their cross-section is I-shaped and they are fixed with bolts and anti-slip pads. The number of upper-layer supports 5 is twice that of lower-layer supports 6, distributing the upper load. Lower-layer supports 6 are fixed to the arched support frame 4 with bolts and anti-slip pads. The arched support frame 4 and the lateral support frame 3 are also fixed with bolts and anti-slip pads. The connecting seat 7 has a hollow internal structure with holes in the side walls to accommodate the arched support frame 4 and the lower-layer supports 6. Anti-slip rubber pads are provided at the connection point to enhance stability. Connector 8 and connecting seat 7 are designed as a single unit. The lower end of the connector 8 is provided with a connecting flange 11. The mating rod 9 and the connecting flange 11 are integrated into one piece, with a "T"-shaped cross-section. The universal ball 10 is fixed to the two mating rods 9 by a pivot and fasteners. The mating screw hole 12 at the lower end of the mating rod 9 serves as the insertion hole for the extension rod. Insertion holes are made in the hole wall to insert the round rod, improving the stability of the extension rod.
