The invention discloses a construction method and post-cast section supporting device of a prefabricated concrete column. The post-cast section supporting device of the prefabricated concrete column comprises a plurality of prefabricated steel formworks and fastening pieces; the prefabricated steel formworks surround a post-cast section of the prefabricated concrete column and are connected by thefastening pieces, one prefabricated steel formwork is provided with an opening, and the opening is provided with a funnel. According to the construction method and post-cast section supporting deviceof the prefabricated concrete column, the supporting device is arranged at the post-cast section of the prefabricated concrete column, when site construction personnel carry out post-cast section construction, concrete can be vibrated, the construction quality can be effectively improved, and the repair expense in the later period is reduced. The construction method and post-cast section supporting device of the prefabricated concrete column have the advantages that the operation is simple and convenient, the construction is quick and convenient, and the whole construction period cannot be affected.
Description
Technical field [0001] The invention relates to the field of building construction, in particular to a construction method of a precast concrete column and a post-casting section support device. Background technique [0002] The post-cast section of precast UHPC (Ultra-High Performance Concrete) column cannot be vibrated when the UHPC is poured, and the concrete will not be dense. In severe cases, holes will appear in the concrete, which will affect the strength of the concrete. Quality will have a big impact. Then it has a great impact on the force between UHPC concrete and steel bars, causing hidden dangers to the quality and safety of the overall structure. [0003] At present, the construction site does not have a unified construction technology for the post-cast section of the precast UHPC column, which often results in holes in the precast column after UHPC pouring, which greatly affects the construction quality. Summary of the invention [0004] The invention provides a con...
