Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a steel pipe connection mechanism and a steel structure dome. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. Steel structure buildings are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopt silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. Welds, bolts or rivets are usually used to connect the components or parts. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields. Prefabricated steel structure has become a hot direction for the development of the construction industry due to its light weight, high strength, good seismic performance, fast construction, short cycle, reusable and less pollution. In particular, its modular characteristics are more in line with the requirements of industrial development and have good application prospects and market potential.

[0003] According to a prefabricated dome-shaped steel structure disclosed in the national patent website (authorization announcement number: CN114164979B), "the present invention discloses a prefabricated dome-shaped steel structure, including a top node assembly, a bottom support ring and a plurality of rib plates, wherein the plurality of rib plates are evenly arranged circumferentially between the top node assembly and the bottom support ring, the rib plates are arc-shaped structures, the plate surfaces of the rib plates are arranged in the vertical direction, the top ends of the rib plates are clamped with the top node assembly, and the bottom ends of the rib plates are clamped with the bottom support ring; the present invention eliminates the use of any bolt connections or welding connections between structural components, facilitates installation and disassembly, reduces construction difficulty, speeds up construction progress, and reduces construction costs; the structure has high strength and strong bearing capacity."

[0004] Although the device is installed by setting up multiple arc-shaped rib plates, the installation is simple and the construction is fast, but the strength and stability of the rib plate connection are relatively low, and are greatly affected by factors such as welding quality. Therefore, in actual use, the structural support using plate ribs is not as good as the steel pipe structure in terms of strength and stability. In order to ensure the stability and durability of the dome structure, we need to design a steel pipe connection mechanism and a steel structure dome. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a steel pipe connection mechanism and a steel structure dome. The device effectively disperses the weight and load of the dome and increases the overall strength of the dome by arranging connection components and support components.

[0006] A steel pipe connection mechanism and a steel structure dome, including a support assembly, including a support plate, a support seat arranged on the support plate, and a support column on the support seat; a connection assembly, including a connection box arranged on the top of the support column, a connection block arranged on the connection box, a locking column arranged on the connection block, an internal thread arranged inside the locking column, a first bolt opening arranged on the surface of the locking column, a locking block arranged on the locking column, and a fixing bolt on the surface of the locking block, wherein the fixing bolt is bolted to the first bolt opening.

[0007] The above technical solution further includes:

[0008] The support assembly also includes a support block, which is fixedly connected to the side of the support plate. A connecting rod is provided at one end of the support block away from the support plate, a limiting block is provided at one end of the connecting rod away from the support block, an insertion interface is provided at the top of the limiting block, and a bottom support ring is provided at the bottom of the limiting block.

[0009] The connecting blocks and locking posts are arranged in eight groups and are distributed around the circumference of the connecting box. The locking blocks are semicircular and slightly larger than the locking posts. The locking blocks can lock the connection and provide auxiliary protection, thereby effectively improving the connection effect and strengthening the overall connection degree of the device.

[0010] The support plate is in a regular octagonal shape, and eight support blocks and connecting rods are provided and distributed around the circumference of the support plate.

[0011] The limit blocks are in the shape of "7". There are eight groups of limit blocks that are evenly distributed on the surface of the bottom support ring. The limit blocks are welded to the surface of the bottom support ring. The bottom support ring supports the entire device and is the supporting point of the entire device.

[0012] It also includes a dome assembly, including a curved portion, a threaded column arranged at the top of the curved portion, and a second bolt hole arranged on the side surface of the top of the curved portion. The curved portion is mainly a curved steel pipe, and both sides of the steel pipe are arranged as straight steel pipes for connecting and fixing the upper and lower ends. At the same time, the dome material cover is arranged on the surface of the curved portion to form a steel structure dome.

[0013] There are eight groups of curved portions distributed around the circumference of the support column. The position and size of the bottom of the curved portion correspond to the position and size of the plug-in interface, and the position of the threaded column corresponds to the position of the internal thread.

[0014] The fixing bolt passes through the locking block and is connected to the second bolt port, the threaded column passes through the locking block and is connected to the internal thread, and the bottom of the curved portion is plugged into the inside of the plug port.

[0015] Beneficial effects:

[0016] 1. The steel pipe connection mechanism and the steel structure dome are provided with connection components. By using the steel pipe connection components, different steel pipe components can be connected together to form a relatively stable and strong structure, which helps to increase the overall strength of the dome and enable it to resist external loads, wind forces, earthquakes and other forces. On the other hand, the manufacture and installation of the steel pipe connection components are relatively simple, which can improve construction efficiency, thereby saving costs and time, and making the construction process of the steel structure dome more efficient and economical.

[0017] 2. The steel pipe connection mechanism and the steel structure dome are provided with a support assembly. By setting up multiple sets of connecting rods and supporting columns, on the one hand, sufficient bearing capacity can be provided to support the entire dome structure, which helps to disperse the weight and load of the dome and reduce the deflection and deformation of the dome structure. On the other hand, by adjusting the length, angle and position of the supporting columns, the shape of the dome can be fine-tuned to meet the design requirements, so as to correct the deviation of the dome caused by construction errors or deformation.
