Background The steel template for road construction is a temporary supporting structure for road construction, and can provide a stable foundation for road construction. The road steel form comprises a steel form plate, a supporting frame, an end connector, a clamp and bolts, wherein the steel form plate is made of a high-strength steel plate and has higher bearing capacity and stability, the supporting frame is made of steel pipes and is used for supporting and stabilizing the steel form, the end connector is used for connecting the steel form plate and the supporting frame to ensure the stability of the whole road steel form, and the clamp and bolts are used for fixing the steel form plate and the supporting frame to increase the overall stability and safety. In the construction process of a steel form for road construction, it is generally necessary to follow the process of locating and measuring the road before construction to determine the width and length of the road. The number and the size of the required steel templates are determined according to the size of the road, and the steel template plates and the supporting frame are assembled firstly. And determining the number and arrangement modes of the steel template plates according to the width and the length of the road. The support frames are then arranged at intervals and connected together using end connectors. And finally, fixing the steel template plate on the supporting frame, and fixing by using a clamp and a bolt, wherein after the installation is finished, the steel template plate needs to be adjusted to ensure that the horizontality and the verticality of the steel template plate meet the requirements. The steel form can be finely adjusted by adjusting the height of the supporting frame and using the adjusting bolts, and after the steel form is installed, the steel form is inspected and checked, so that the installation quality and stability of the steel form are ensured. The inspection includes checking whether the connection members of the steel form are firmly fixed, whether the steel form plate is deformed or damaged, etc. The traditional concrete road construction adopts an integral pouring mode, the construction period is long, and a large amount of manual operation is needed, so that the construction efficiency is low and the construction quality is unstable. In addition, traditional road template construction elevation can't be adjusted, and the dowel bar is reserved pre-buried troublesome, and some still need the cutting destroy original steel form, and the template is installed and is consolidated and demolishd difficulty and the road template is more time consuming and laborious when repeatedly transporting the use, greatly increased engineering time and construction cost. Therefore, there is a need for an improved concrete pavement steel form construction and construction method that solves the above-mentioned problems. Disclosure of Invention Aiming at the problems that the construction elevation of the traditional road template cannot be adjusted and the reservation and embedding of the dowel bar are troublesome, the invention provides an improved concrete road construction template which is easy to adjust the elevation of the template, reserve and embed the dowel bar, quickly and stably strengthen, dismantle and transport.
