Problems solved by technology
In the construction where T-shaped steel beams are installed on the roof steel beams, due to the large span of the roof steel beams, when the T-shaped steel beams are welded and installed, welding deformation of the T-shaped steel beams and roof steel beams is prone to occur on site, which reduces the T-shaped beam. The installation accuracy of the steel beams leads to a decrease in the installation accuracy of the winch equipment, which seriously affects the construction quality

Abstract
The large-section T-shaped steel beam high-precision single-side welding construction structure comprises a plurality of T-shaped steel beams, the T-shaped steel beams are variable-section steel beams, the top end face of each T-shaped steel beam is welded and fixed to the bottom end face of a roof steel beam in the length direction, all the T-shaped steel beams are welded and fixed, and the top end face of each T-shaped steel beam is welded and fixed to the bottom end face of the roof steel beam. A plurality of first anti-welding deformation rib plates are welded on one side surface of the roof steel beam at intervals, and a plurality of second anti-welding deformation rib plates are welded on one side surface of the T-shaped steel beam at intervals; and the number of the positioning angle steel is multiple, a transverse plate of each positioning angle steel is welded and fixed to one side face of the roof steel beam, and vertical plates of the positioning angle steel extend downwards and are connected through the hoisting detection control line. The structure effectively controls the mounting and welding precision of the large-section T-shaped steel beam, so that the welding construction quality of the large-section T-shaped steel beam is high, the deformation is small, and the high-precision requirement of T-shaped steel beam component mounting is met.
Description
technical field [0001] The invention relates to the technical field of civil engineering, in particular to a high-precision single-sided welding construction structure and construction method of a large-section T-shaped steel beam. Background technique [0002] At present, when installing the hoist guide rail under the roof steel beam, the roof is structurally sloping, resulting in a height difference between the two ends of the roof steel beam. However, since the installation of the winch equipment requires the rooting point to be horizontal, the T-shaped steel beam is added as a variable Section beams, wherein the web height of T-shaped steel beams is 155.12-663.02mm. In the construction where the T-shaped steel beams are installed on the roof steel beams, due to the large span of the roof steel beams, when the T-shaped steel beams are welded and installed, the on-site welding deformation of the T-shaped steel beams and the roof steel beams is prone to occur, which reduces...
