Description

Technical Field

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

[0002] At present, in building construction, in order to prevent cracks in reinforced concrete structures due to shrinkage and other reasons, a post-cast strip is left in the middle of the casting position when casting walls, beams and other parts. After the concrete on both sides of the post-cast strip is poured, the post-cast strip is poured again after the concrete is completely solidified (referring to solidification until its strength reaches the required level) to connect the structure into a whole zone; specifically, before pouring, a formwork, a keel and a support frame are arranged in sequence below the casting position, and the concrete is poured on the formwork. The keel is used to evenly bear the formwork to prevent the formwork from being deformed by force. The support frame stands on the ground to support the bottom surface of the keel. The support frame is large in scale and consists of modular components. The support frame must be located below the casting position for support from before pouring until the post-cast strip is completely solidified. When the concrete on both sides of the post-cast strip is completely solidified, there is no need for a large-scale support frame to provide such a high support capacity, resulting in the support frame being very redundant, and a large number of modular components being equivalent to being idle and unable to be effectively utilized.
