Description

Technical Field

[0001] The utility model relates to the field of bridge construction, in particular to a bridge support cushion stone template with adjustable height and flatness. Background Art

[0002] The construction of bridge support pad stones has high requirements on structural dimensions, plane position and top surface flatness. The quality of pad stone construction directly affects the quality of precast beam erection, especially the top surface elevation and flatness of the pad stone are the most critical. Due to the design of the horizontal slope on the top surface of the cap and the positioning not being polished during the pouring process, the heights of the four corners of the support pad stone are not the same. The installation height of the template top surface is difficult to control, and a template with a height greater than the thickness of the pad stone is often used for installation. The top surface flatness is difficult to control when pouring concrete. Before the erection of the beam body in the later stage, personnel need to be arranged to re-polish the top surface of each pad stone, which consumes a lot of manpower. Sometimes the polishing effect is difficult to meet the error requirements of the specification, which will directly affect the erection quality of the precast beam and the service life of the support pad stone. In addition, a large gap will be formed between the side template and the top surface of the cap, which can only be sealed by applying foam glue. After the mold is removed, the bottom of the pad stone will form a rough surface.

[0003] Therefore, it is necessary to provide a bridge bearing pad stone template with adjustable height and flatness to solve the above technical problems. Utility Model Content

[0013] Compared with the related art, the bridge support pad stone template with adjustable height and flatness provided by the utility model has the following beneficial effects:

[0014] The utility model provides a bridge support stone template with adjustable height and flatness:

[0015] 1. Adjust the height of the four corners of the template frame through the height adjustment screws at the four corners, directly adjust the top surface elevation of the upper horizontal stainless steel template and the upper vertical stainless steel template to the design elevation, and directly smoothen the concrete surface on the template frame. This can further improve the flatness of the top surface of the cushion stone, reduce the cost of grinding and polishing the top surface of the cushion stone in the later stage, ensure the quality of prefabricated beam erection, and improve the service life of the bridge bearing.

[0016] 2. The overall flatness of the template can be directly observed through the spirit level on the outside of the upper template. There is no need to use a spirit level to measure and adjust each side. The top surface of the template can be leveled while adjusting the elevation of the top surface of the template, which improves efficiency.

[0017] 3. By adjusting the lifting and lowering of the lower template, the template can better adapt to the horizontal slope of the top surface of the platform cap, better fit with the concrete surface of the top surface of the platform cap, adapt to the construction of support pads of different thicknesses, and have a higher template turnover construction rate.
