Technical Field

[0001] The utility model relates to the technical field of templates, in particular to a quick template for highway construction. Background Art

[0002] Highway construction formwork, also known as highway formwork or road engineering steel formwork, is usually made of multiple steel plates spliced ​​together and has a large length and width to meet the different needs of highway construction. This formwork can be installed at the construction site and can be disassembled and adjusted as needed. During the highway concrete pouring process, the formwork can withstand the weight of the concrete and maintain its fixed shape to prevent concrete loss or deformation.

[0003] The current highway construction formwork still has the following shortcomings in actual use: when pouring concrete in highway construction, the pouring of concrete easily causes the formwork to fit tightly to the concrete surface. Usually, hammers, impactors and other equipment are used to assist in removing the formwork, while the traditional disassembly method usually uses knocking to dismantle. If the adhesion between the concrete and the formwork is too large, the force of knocking and impact may be large, which may easily cause damage to the formwork, thereby affecting the repeated use of the formwork. Therefore, a fast highway construction formwork is needed to solve the above problems. Utility Model Content
