Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel structure support frame assembled according to standard sections. Background Art

[0002] In the field of architecture, with the continuous development of the construction industry and people's pursuit of aesthetics, many tall, large-span buildings have emerged. These architectural models break with traditional rules. Some giant diagonal trusses have a clear bottom and no support system. During construction, the trusses are assembled in sections, which is extremely difficult to install and difficult to ensure safety and stability. The use of temporary support frames as load-bearing support tools can effectively solve this problem and also serve as temporary support during the construction of prefabricated buildings. In the bridge industry, support frames are used to locate bridges, mark and measure benchmarks, and ensure the correct appearance of sections during welding, providing good assembly and welding working conditions. In the shipbuilding industry, frame frames are widely used in the construction of sections such as hull bottoms, decks, sides, and bows and sterns. Whether for small or medium-sized ships or large vessels, frame frames effectively ensure the smooth assembly and welding of sections.

[0003] However, in actual application, the use of support frames still has some drawbacks: substandard materials, poor welding quality, deviations in support frame installation, deviations in diagonal brace welding quality, the difficulty of cutting and assembling materials on site according to drawings, extensive welding and cutting during dismantling, and low recycling and reuse rates. These drawbacks not only affect the safety and stability of the project but can also lead to delays and increased costs.

[0004] To solve the above problems, the Chinese patent application number 202011271234.1 discloses a temporary support frame for the installation of assembled lattice steel structures and a method of use. The temporary support frame disclosed above includes a base section, a standard section, an adjustment section inner section, an adjustment section outer section, an adjustment top support, and a jack for unloading; the base section includes a base section column limb, a base section tie bar, and a base section cross beam; the standard section includes a standard section column limb, a standard section tie bar, and a standard section cross beam; the adjustment section inner section includes an adjustment section inner section column limb, an adjustment section inner section tie bar, and an adjustment section inner section cross beam. Chinese patent application number 202120011732.6 discloses a temporary support frame for steel structure construction. The temporary support frame disclosed above includes columns, the upper parts of which are connected to each other through upper chords, and the lower parts of the columns are connected to each other through lower chords. A flange is provided at the top of the column, and an ear plate is provided on the outside of the column under the flange; a flange is provided at the lower end of the column. The bolts of the utility model assemble the columns, webs, chords and pipe brackets into a standard section of a lattice bracket, and the lattice brackets are connected with flanges to realize a multi-module assembly structure.

[0005] The standard sections, base sections, etc. in the above-mentioned prior art are all temporary support structures. When faced with different support heights, the existing support frame does not match the height to be supported and cannot meet the support requirements of different support heights. Therefore, it is necessary to cut on-site according to the actual size to meet the support needs. This method is less efficient, and the size of the cut support frame is prone to errors, which makes the size of the support frame smaller, resulting in reduced bearing capacity. Utility Model Content

[0006] The utility model aims to overcome the defects in the above-mentioned prior art and provide a steel structure support frame which can adjust the support height of the support frame and realize the support demand for the support height and is assembled according to standard sections.
