Technical Field
[0001] The utility model relates to the technical field of pavement concrete pouring construction, in particular to a portable locking type cast-in-place template for pavement construction. Background Art
[0002] There are two types of traditional roadbed formworks, channel steel or wooden squares. Manual alignment is often required during formwork installation. Gaps and misalignment are inevitable between formworks, and the back of the formwork is often fixed by driving a steel chisel or a wooden wedge into the lower base. The formwork is separate from the formwork, and is often squeezed by the poured concrete in the width direction due to weak support, and is prone to tilting and running, affecting the straightness of the base concrete. Therefore, a portable cast-in-place formwork is designed that can ensure flush joints, is not easy to misalign, and is firmly positioned and fixed, so as to improve the molding quality that affects the roadbed pouring.
