Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an adjustable bottom supporting structure of a template support system. Background Art

[0002] Due to the particularity of the plateau environment, there is freeze-thaw phenomenon in the plateau soil, including permafrost and seasonal frozen soil, especially seasonal frozen soil, which has a serious impact on the stability of buildings. In order to reduce the impact of soil freezing and thawing on buildings, building design generally uses pile foundation columns to support raised floors to isolate the building floor from the soil, so as to reduce the impact of soil freezing and thawing on buildings.

[0003] At present, when construction is carried out on a natural slope of frozen-thawed soil, especially on frozen-thawed soil, it is usually necessary to first use an integral plate pad on the slope, fix the support poles on the pad, then fix the support poles on the pad, and then construct the formwork support. After the base plate construction requirements are met, the base plate is constructed. The overall construction process is cumbersome. In addition, since the original landform still has the problem of slope change, directly constructing the integral plate pad on the original landform will also cause serious damage to the original landform, and the adaptability is not strong.

[0004] Based on this, the inventor has designed an adjustable bottom support structure for the formwork support system to solve the problem of destroying the original topography of the soil and causing construction troubles when the formwork support system is erected, and thus, the present application is proposed.
