Abstract
Description
A reusable column support for precise positioning and installation of large-span orthogonal steel trusses Technical Field
[0001] This utility model relates to a reusable column support for precise positioning and installation of large-span orthogonal steel trusses, and particularly relates to the field of building engineering technology. Background Technology
[0002] With the development of science and technology and the updating of architectural concepts, the application of large-span steel truss structures in buildings is becoming more and more widespread. This structural form not only provides buildings with more space and higher load-bearing capacity, but also has significant advantages in terms of construction speed, economy and adaptability. Precise installation of large-span steel truss structures is crucial to ensuring the safety and functionality of the structure. Any installation error may lead to a decline in structural performance or even cause safety accidents. In the traditional installation process of large-span steel truss structures, the use of a jig for installation and welding is an important link. Although the jig of the large-span steel truss structure plays an important supporting and fixing role in the manufacturing and installation process, it also has some disadvantages and limitations: (1) Temporariness: The jig is a temporary structure that needs to be dismantled and removed, which increases construction costs and time. (2) Complexity: The design and manufacturing of the jig requires consideration of various factors, such as structural size, shape, load, etc., and the design process is relatively complex. (3) Weight and volume: The jig is usually made of steel and has a certain weight and volume, requiring large lifting equipment for handling and installation. (4) Cost: The fabrication and installation of the formwork requires certain materials, labor, and equipment, increasing construction costs. (5) Construction space: The formwork requires a certain amount of construction space, which may affect other construction activities. (6) Low reuse rate: The formwork is usually a custom structure with a low reuse rate, requiring redesign and fabrication for different projects. The vertical component bracket is welded to the large-span steel truss using limiting plates, which has poor stability. It is difficult to ensure welding accuracy for large-span steel trusses. At the same time, for bolted hinges, the presence of limiting plates will restrict the displacement of the steel structure, which may affect the deformation and internal force distribution of the structure under stress, reduce the seismic performance of the structure, and cause stress concentration at the contact point between the limiting plate and the steel structure, leading to local fatigue damage. Summary of the Invention
[0003] This invention provides a reusable column support for precise positioning and installation of large-span orthogonal steel trusses, overcoming the shortcomings of complex installation and high cost of existing large-span steel truss structures.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model discloses a reusable column support for precise positioning and installation of large-span orthogonal steel trusses, including a steel column, an annular steel column hoop connected to the steel column by high-strength bolts, a triangular steel platform welded to the annular steel column hoop, and steel column brackets on both sides of the steel column for welding to the large-span orthogonal truss steel beams.
[0006] Furthermore, the triangular steel platform is welded to both sides of the annular steel column hoop.
[0007] Furthermore, steel stirrups are provided on the upper surfaces of both sides of the triangular steel platform for adjusting the position of the large-span orthogonal truss steel beams and welding them together.
[0008] Furthermore, both the annular steel column hoop and the triangular steel platform are detachable. The beneficial effects achieved by this invention are as follows: Steel column hoops and triangular steel platforms are hinged to the steel columns at the supports on both sides of the large-span steel structure. The triangular steel platform serves as a support point for the large-span steel truss and also as a support for welding the vertical corbels to the large-span steel truss, providing stable support for welding and helping welders maintain the welded parts in the correct position and angle. During the welding of the large-span steel truss, the support prevents displacement of the welded parts due to gravity or welding heat during the welding process, while providing uniform support force, helping to reduce thermal deformation during welding, and maintaining the original shape and dimensions of the steel structure; thus ensuring the accuracy and quality of the welding. The hinged connection effectively ensures the quality of the steel and avoids damage to the base material, solving both the accuracy and quality issues of welding the large-span steel truss to the vertical corbels, while reducing the need for a welding jig.
