Problems solved by technology
[0003] At present, in temporary prefabricated steel structures, especially in deep foundation pit prefabricated steel support systems, measures such as tape measure and wire measurement are usually used. These rough measurement methods will lead to large installation errors, especially for components. For a long time, the accumulation of errors will cause a large eccentricity of such compression members after installation, greatly reducing their bearing capacity, thus affecting the safety of the structure or support system
[0004] If the total station and other technologies are used for measurement and installation, sufficient accuracy requirements can be guaranteed, but it is difficult to select measuring points for shorter components, and for components with more segments, there are more measuring points, and retesting is required for each adjustment , it is not intuitive and the continuity is not strong, and it takes a long time to affect the construction period

The invention provides a profile steel supporting and straightening apparatus and an application method thereof. The profile steel supporting and straightening apparatus comprises multiple sections ofprofile steel which are horizontally connected, a laser transmitter, a first straightening assembly and a second straightening assembly, wherein the first straightening assembly is arranged on a first section of profile steel, the second straightening assembly is arranged on a last section of profile steel of the multiple sections of profile steel, the profile steel between the first section ofprofile steel and the last section of profile steel is provided with the first straightening assembly, the first straightening assembly comprises a first plate body with a center hole, the second straightening assembly comprises a second plate body with a center point, and the laser transmitted by the laser transmitter horizontally penetrates through the center hole to be projected to the center point. According to the application method provided by the invention, the profile steel is straightened by observing the laser point penetrating through the center hole to be projected to the relativeposition of the center point through laser radiation, so that the operation is convenient, and the efficiency is high.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a section steel support straightening device and a use method thereof. Background technique [0002] At present, there are more and more structures and components using fabricated section steel, and more and more fabricated section steel components are subjected to axial pressure. Compression members are further increased. However, there is a problem of buckling instability in axially compressed members, and the bearing capacity of axially compressed members is not only related to the restraint types at both ends, but also related to their initial eccentricity. [0003] At present, in temporary prefabricated steel structures, especially in deep foundation pit prefabricated steel support systems, measures such as tape measure and wire measurement are usually used. These rough measurement methods will lead to large installation errors, especially for components. For...
