Description

Technical Field

[0001] The utility model relates to the technical field of steel truss beams, in particular to a steel truss beam adjustment structure. Background Art

[0002] A steel truss bridge is a structural form in which a solid steel plate beam bridge is hollowed out according to certain rules. The overall structure is subjected to stress in the manner of a beam. Since steel has many advantages such as high strength, uniform material, good plasticity and toughness, and good weldability, bridges built with steel can increase the strength and spanning capacity of the bridge. When installing steel trusses, the distance between the mounting blocks needs to be adjusted according to the width of the steel trusses.

[0003] There are still some problems with the common steel truss adjustment structure. For example, when adjusting the distance between the mounting blocks, the center points of the two sets of mounting blocks may not be on the same horizontal line due to external forces. The offset of the two sets of mounting blocks not only affects the installation efficiency, but also requires moving the mounting blocks again, which is time-consuming and labor-intensive.

[0004] Therefore, we proposed a steel truss adjustment structure to improve the above-mentioned problems. Utility Model Content

[0015] Compared with the prior art, the utility model has the following beneficial effects: the steel truss adjustment structure not only realizes the convenience of limiting the installation block and the support block during the limit adjustment process, but also realizes the convenience of measuring the distance between the two groups of installation blocks;

[0016] (1) By providing a rotating block, a rotating groove, a threaded sleeve and a threaded rod, the threaded sleeve is rotated when the distance between the first mounting block and the second mounting block needs to be adjusted. Since the threaded sleeve and the threaded rod cooperate with each other and the rotating block rotates outside the rotating groove, the threaded sleeve can be rotated to adjust the distance between the first mounting block and the second mounting block according to the needs of the user, thereby facilitating the installation of steel trusses of different widths on the top ends of the first mounting block and the second mounting block.

[0017] (2) By providing a first support block, a second support block, a limiting rod, a reserved groove, a ball and a rolling groove, the first support block and the second support block can further support both sides of the steel truss beam. When the first mounting block and the second mounting block move, the limiting rods on both sides of the second support block will slide inside the reserved groove, thereby further limiting the second support block to prevent the second support block from shifting. The ball inside the rolling groove can reduce the friction between the reserved groove and the limiting rod, thereby preventing the resistance generated by the friction between the limiting rod and the reserved groove from affecting the movement of the first mounting block and the second mounting block;

[0018] (3) By setting a limit frame, a measuring ruler, a limit slot and a fixing pin, the right side of the measuring ruler is inserted into the interior of the limit frame, and then the limit slot on the left side of the measuring ruler is aligned with the limit slot on the right side of the front end of the first mounting block. After the limit slots are aligned, the fixing pin is inserted into the interior of the limit slot, so that the measuring ruler can be fixed. The measuring ruler can facilitate the staff to clearly observe the distance between the first mounting block and the second mounting block, thereby improving the accuracy of adjusting the distance.
