Description

Technical Field

[0001] The utility model relates to the technical field of construction formwork, in particular to a shoulder concrete construction formwork. Background Technique

[0002] The shoulder refers to a strip part with a certain width located at the outer edge of the carriageway to the subgrade edge, including a hard shoulder and a protective shoulder. It is used to maintain the function of the carriageway and for temporary parking, and serves as the lateral support of the road surface. During its construction process, construction formwork is often required.

[0003] At present, most of the existing shoulder construction formworks are spliced together section by section, and then a support structure is provided at the rear of the construction formwork through a strut / steel bar (as shown in the physical drawing provided in the specification). However, when disassembling this shoulder construction formwork, the formwork and the support structure cannot be stored together, and need to be carried separately, resulting in inconvenient carrying.
