Description

Technical Field

[0001] The utility model belongs to the technical field of building frames, in particular to a steel structure frame. Background Art

[0002] Steel frames are primarily constructed of steel and are a major type of building structure. Firstly, their high strength, light weight, and high rigidity make them particularly suitable for constructing large-span, ultra-tall, and ultra-heavy buildings. These characteristics give steel frames significant advantages in buildings that must withstand heavy loads or span large spaces. Secondly, the material of steel frames is highly homogeneous and isotropic, representing an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. This means that when subjected to stress, steel frames exhibit relatively uniform deformation and stress distribution, contributing to the stability and safety of the structure.

[0003] Announcement No. "CN222101134U" discloses a steel structure frame, relating to the technical field of building frames, which solves the problem of low installation efficiency of existing building frames. The frame comprises four pillars, each of which has four sets of first slots formed on its surface. First support rods are mounted on each of the pillars, and first blocks are mounted on both ends of the first support rods. The first blocks match the first slots. Threaded holes are formed on the surfaces of the first support rods and pillars, and bolts are installed in the threaded holes. By using the first slots, first support rods, first blocks, threaded holes, and bolts in combination, this device can quickly secure the support rods, eliminating the need to support the support rods until installation is complete, greatly improving installation efficiency.

[0004] Although the above-mentioned utility model can quickly fix the support rod through the coordinated use of the first slot, the first support rod, the first block, the threaded hole and the bolt, and there is no need to support the support rod until the installation is completed, thereby greatly improving the installation efficiency, the pillar and the first support rod are directly fixed. Under the condition of large force, the connection point between the pillar and the first support rod is prone to loosening or damage, and higher installation accuracy is required. Once fixed, it is difficult to adjust it, and the flexibility of adjusting or reconfiguring the structure when necessary is limited. Utility Model Content

[0008] As an optimal technical solution, the positioning assembly includes a built-in hole, a return spring and a positioning column. A built-in hole is provided on each outer surface of the second pillar. A return spring is fixedly connected to one end of the built-in hole, and a positioning column is fixedly connected to the other end of the return spring.

It can also greatly simplify the construction and installation process, facilitate construction workers to install quickly and accurately, and can also achieve the combination of prefabrication and on-site assembly to improve construction efficiency.

[0015] Second, in the present invention, when the connecting head is combined with the upper end of the second pillar, the second pillar is inserted into the interior of the connecting head. During the insertion process, pressure is applied to the arc surface of one end of the positioning column, so that the positioning column is pressed against the reset spring, the reset spring is compressed, and the positioning column retracts into the built-in hole. When the positioning column moves to the positioning hole, the reset spring is reset, and the positioning column pops out and engages with the positioning hole to complete the positioning of the connecting head and the second pillar during assembly. It can ensure the accurate positioning between the second pillar and the connecting head, avoid deviation or misalignment during the installation process, ensure the overall stability and bearing capacity of the steel structure frame, thereby improving the safety and reliability of the entire structure, and can effectively restrain the relative displacement between the first pillar and the connecting head, thereby enhancing the rigidity of the entire steel structure frame.
