Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a large-volume concrete beam formwork support structure for a super-large bridge cap. Background Art

[0002] During the construction of large-volume pedestal concrete, due to the large amount of concrete poured at one time and the large span of the formwork, it is very easy to cause the formwork to expand, bend, deform, displace, collapse, and explode during the pouring process. In order to ensure the construction quality of large-volume pedestal concrete and the safety of the construction site, formwork reinforcement measures are usually taken.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN215947901U discloses a large-volume concrete pedestal formwork support system, including: a left side form, a right side form, a front side form, a rear side form and a support structure; the first support layer, the second support layer, the third support layer and the fourth support layer of the support structure; the first support layer includes a first transverse tension screw connecting the left side form and the right side form, and a first longitudinal tension screw connecting the front side form and the rear side form; the second support layer includes a second transverse steel strand connecting the left side form and the right side form, and a second longitudinal steel strand connecting the front side form and the rear side form; the third support layer includes a third transverse steel strand connecting the left side form and the right side form, and a third longitudinal steel strand connecting the front side form and the rear side form. The present application solves the problem that the pedestal formwork support system in the related art uses a large number of tension screws, which increases the possibility of forming a rust channel, and the problem of expansion of the formwork caused by the breakage of the tension threaded steel bars is easy to occur during tensioning.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that when the pedestal is poured, a formwork needs to be installed at the outer end, and a supporting structure needs to be installed at the outer end of the formwork. When the traditional supporting structure is used, the concrete is poured too quickly, which can easily cause the formwork to explode and deform, resulting in the need for subsequent manual inspection and adjustment, affecting the overall pouring efficiency. When the supporting structure is used, the supporting structure is large, resulting in the inability to transport and install quickly afterwards. The existence of these problems affects the use of the device. Utility Model Content
