Embodiment Construction
[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0052] refer to figure 1 , shows a schematic structural view of the displacement adjustment device for H-shaped steel supports of the present invention. Such as figure 1 As shown, the displacement adjustment device for H-shaped steel support of the present invention includes: a base 20 detachably fixed on the joist 10; an adjustment rod 30 inserted vertically and screwed to the base 20; detachably fixed on the adjustment The support structure 40 at the top of the rod 30; and a plurality of clamping structures located on the opposite sides of the support structure 40 for clamping the H-shaped steel support, the clamping distance of the clamping structure is adjustable; Move up and down inside to adjust the distance between the H-shaped steel support and the joist to ensure that the H-shaped steel support is always in a straight state.

The invention relates to a displacement adjusting device for an H-shaped steel support and a construction method thereof. The device comprises a base detachably fixed to a joist, an adjusting rod vertically inserted and screwed to the base, a supporting structure detachably fixed to the top of the adjusting rod and a plurality of clamping structures arranged at the opposite sides of the supportingstructure and used for clamping the H-shaped steel support; the clamping distances of the clamping structures can be adjusted; by adjusting the adjusting rod to move up and down in the base, the distance between the H-shaped steel support and the joist is adjusted to ensure that the H-shaped steel support is always in a flat straight state. When a steel column and the joist arranged on the steelcolumn uplift or sink, by adjusting the adjusting rod of the device to move up and down in the base, the H-shaped steel support does not deflect downward or upward along with uplifting or sinking of the steel column, so that the H-shaped steel support is always in the flat straight state, and the device helps to maintain the stability of the H-shaped steel support.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a displacement adjustment device for H-shaped steel supports and a construction method thereof. Background technique [0002] H-shaped steel supports have been widely used in many foundation pit projects at home and abroad. The two ends of the H-shaped steel are connected to the steel purlins, the middle of the H-shaped steel is placed on the joist, and the two ends of the joist are connected to the steel column by welding. [0003] However, in the field application process, with the excavation of the foundation pit, the steel columns will bulge and drive the joists to bulge together. When the height of the steel purlins remains unchanged, the part of the H-shaped steel that rests on the joists will also follow. Bending the protrusion upwards results in deflection of the H-shaped steel support. Under the action of the axial force of the H-shaped steel support, it will cause...
