The invention provides a movable supporting assembly for reinforcing a line transverse beam. The movable supporting assembly comprises a movable support, angle steel, supporting square timber, a plurality of bolts and a wooden wedge, wherein the transverse section of the movable support is shaped like a reversed Chinese character 'ao' and two lower ends extend inward and horizontally respectively to from one edge, so that a groove for clamping a transverse beam upper flange plate of I-shaped steel is formed; the lower ends of the plurality of bolts penetrate through the top of the movable support and extend into the groove; the outer end of a horizontally arranged side edge of the angle steel is clamped into a gap between the top surface of the groove of the movable support and the transverse beam upper flange plate; the tip of the wooden wedge is clamped into the gap between the top surface of the groove at the outer side end of the movable support and the transverse beam upper flange plate; and the two ends of the supporting square timber abut against the other vertically arranged side face of the angle steel and one side of an upper flange plate of a steel rail. The movable supporting assembly has the advantages of simple structure, low cost and convenience for operation, and the position can be adjusted by adopting the wooden wedge. One time of measure of technically controlling sizes is increased in a link of penetrating the transverse beam.
Description
technical field [0001] The invention belongs to the technical field of railway construction devices, in particular to a movable support assembly for reinforcing a line beam. Background technique [0002] At present, in railway construction projects, the line reinforcement technology of large rail system has been widely used as a mature construction technology. Weaknesses of control. figure 1 It is a schematic diagram of the state of use of a support assembly for reinforcing line beams in the prior art. Such as figure 1 As shown, the supporting assembly for strengthening the line beam includes angle steel 2 and supporting square wood 3 as a stopper; one side of the angle steel 2 is welded on the upper flange of the beam 1 made of I-beam, and the supporting square The two ends of the wood 3 respectively abut against the other side of the angle steel 2 and one side of the upper flange plate of the rail 4 for supporting the rail 4 . However, there are following problems in t...
