Description

Technical Field

[0001] This utility model relates to the technical field of building engineering, and in particular to a fully bolted steel frame structure. Background Technology

[0002] Currently, the structural systems used in multi-story steel structure buildings mainly include lightweight steel structure systems and traditional steel frame structure systems.

[0003] In some fully bolted steel frame structures, such as the fully bolted side plate connected steel frame structure system disclosed in invention patent application number 202210888773.2, the beam-column joints in the steel frame structure system disclosed in this invention are connected by bolts on the construction site, eliminating the need for welding. One end of the connecting component used at the beam-column joint is pre-welded to one of the components to be connected in the factory, and the other end of the connecting component has pre-set bolt holes in the factory. During assembly on the construction site, only bolts are needed to complete the connection with the other component, which not only reduces the number of bolts by half but also saves assembly time. In this invention, the rigid beam-column joint uses angle steel pre-welded to the flange of the steel beam and bolted together with a side plate pre-welded to the steel column. The side plate is parallel to the web of the steel column, which not only strengthens the joint area of ​​the steel column but also serves as a node plate for connecting the steel beam and the steel column.

[0004] Lightweight steel structure buildings mainly use ribbed load-bearing structures composed of cold-formed thin-walled steel sections. However, due to their light weight and weak lateral stiffness, they are currently mainly used in low-rise residential buildings. The original practice was to process the cold-formed thin-walled steel sections in the factory and then transport them to the site for installation. Due to the wide variety of sizes and specifications, the installation efficiency was low, and the installation quality and accuracy were difficult to guarantee. In traditional steel frame structure systems, the columns at beam-column joints need to be disconnected to install stiffening ribs, which increases the amount of welding and makes it difficult to guarantee the stress performance of the joints. During on-site installation, beam splices are connected by welding or bolt welding, which increases the difficulty of on-site installation. At the same time, the on-site foundation of traditional steel frame structures is generally a cast-in-place concrete foundation, which leads to an increase in the construction period.

It offers different structural systems for different usage environments and installation conditions, with a wide range of applications. The foundation uses precast concrete independent foundations, which can be directly positioned on-site, avoiding on-site foundation pouring and greatly shortening the construction cycle. The beam and column components of this utility model are lightweight, facilitating installation and transportation. Furthermore, the frame columns, frame beams, and foundations are all prefabricated in the workshop and transported to the site for installation, eliminating on-site welding and wet work.

The beam-column joint adopts the end plate type joint, and the H-shaped steel column splicing joint adopts the end plate type splicing joint.

7. A fully bolted steel frame structure as described in claim 6, characterized in that, The beam-column hinged connection frame-braced structure mainly consists of steel columns, steel beams, and bracing. Steel columns can be rectangular steel pipes or H-beams, while steel beams should preferably be hot-rolled or ordinary welded H-beams. The horizontal width of the bracing should be 1.0-1.5m, and the cross-section of the bracing can be channel steel, H-beams, or rectangular steel pipes. The beam-column joints are mostly hinged connections depending on the structural stress conditions. The bracing is hinged to the beams and columns, and the bracing can be arranged according to the building function across spans. The beam-column hinged connection frame-steel plate wall structure mainly consists of steel columns, steel beams, and steel plate walls. Steel columns can be rectangular steel pipes or H-beams, while steel beams should preferably be hot-rolled or ordinary welded H-beams. The steel plate walls should preferably be corrugated steel plate walls. The beam-column joints are mostly hinged connections depending on the structural stress conditions, and the steel plate walls can be arranged according to the building function across spans.

8. A fully bolted steel frame structure as described in claim 7, characterized in that, The semi-rigid column-supported frame structure mainly consists of semi-rigid steel columns, steel beams, and supports. The steel columns can be rectangular steel tubes or H-beams, with semi-rigid connections at the column-to-column joints. The steel beams should preferably be hot-rolled or ordinary welded H-beams, and beam-column connections can be rigid or hinged. The horizontal width of the supports should be 1.0-1.5m, and the support cross-section can be channel steel, H-beams, or rectangular steel tubes. The supports can be arranged according to the building's functional span arrangement. The semi-rigid column-supported frame-steel plate wall structure mainly consists of semi-rigid steel columns, steel beams, and steel plate walls. The steel columns can be rectangular steel tubes or H-beams, with semi-rigid connections at the column-to-column joints. The steel beams should preferably be hot-rolled or ordinary welded H-beams, and beam-column connections can be rigid or hinged. The steel plate walls should preferably be corrugated steel plate walls, and the steel plate walls can be arranged according to the building's functional span arrangement.
