Problems solved by technology
[0004] 1. The locking fixture of the reinforcing bar ring is poorly targeted. Each locking fixture can only support and lock the reinforcing bar ring on one type of reinforcing bar formwork, and the locking of the reinforcing bar ring is unstable, so that when the reinforcing bar ring and the stirrup are welded cause an impact;
[0005] 2. When the stirrup is welded, it needs to be manually adjusted and grasped, so that the stirrup cannot be arranged perpendicular to the steel ring, resulting in poor processing effect of the steel formwork, and there will be certain safety hazards when manually grasping the stirrup

The present invention relates to a manufacturing process for the molded steel bar formwork of municipal concrete prefabricated parts. The manufacturing process for the molded steel bar molded base for municipal concrete prefabricated parts adopts the following manufacturing device for the formed steel bar mold base. The molded steel bar mold base manufacturing device includes a base and an outer support mechanism , expansion plate, adjusting frame, adjusting bolt, positioning mechanism and supporting mechanism; adopting the above-mentioned forming steel formwork manufacturing device to the manufacturing process of municipal concrete prefabricated steel formwork, including the following steps: S1, steel formwork component processing; S2. Adjusting the position of the outer support mechanism; S3. Putting the ring of steel bar; S4. Adjusting the spacing of the ring of steel bar; S5. Welding the stirrup. The present invention can solve the problem existing in the processing and manufacture of steel bar formwork: the locking fixtures of steel bar rings are poorly targeted, each locking fixture can only support and lock the steel bar rings on one type of steel bar formwork, and the steel bar The locking of the ring is unstable, which causes problems such as influence when the steel ring and the stirrup are welded.
Description
technical field [0001] The invention relates to the field of municipal construction, in particular to a manufacturing process for forming a steel bar formwork of a municipal concrete prefabricated part. Background technique [0002] Underground municipal roads are equipped with electricity, telecommunication, heating, gas, sewage, reclaimed water and other pipelines. In order to facilitate the inspection and maintenance of pipelines, manhole covers are required on municipal grounds. Before laying and installing the municipal manhole cover, it is necessary to place a steel formwork on the outside of the manhole cover and pour concrete on the steel formwork to increase the support stability of the manhole cover. [0003] The steel bar formwork is a frame structure formed by two sets of inner steel bar rings and outer steel bar rings distributed up and down through the welding of stirrups. The steel bar formwork can increase the support effect of the manhole cover before instal...
