The present invention also relates to a method for pasting formwork cloth using the self-propelled smoothing and pasting device for concrete formwork cloth. Background Art

[0002] At present, in the process of high-speed railway construction, there are many cast-in-place concrete structures such as bridge piers, and concrete formwork is used frequently. In order to save construction costs, the turnover rate of the formwork is usually increased. In this process, potholes are inevitable on the surface of the formwork. Continuing to use it will easily cause the surface of the cast concrete structure to be irregular, affecting the appearance and durability of the structure. To solve such problems, the industry usually adopts the method of sticking a layer of formwork cloth on the surface of the formwork to improve its flatness, thereby increasing the turnover rate of the formwork and reducing construction costs. As a flexible fiber geotechnical material, the formwork cloth needs to be immediately pasted and regular after spraying special glue. The pasting process usually requires the cooperation of multiple people and is prone to wrinkles, which leads to extended construction period and poor concrete molding quality.

[0003] Currently, there are relatively few construction equipments with functions developed for the template cloth pasting process, and there is an urgent need for equipment that can improve the quality and efficiency of template cloth pasting. Summary of the invention

[0004] In view of the above-mentioned defects existing in the prior art, the present invention provides a self-propelled smoothing and pasting device for concrete formwork cloth, which can automate the whole process of unfolding, smoothing, pasting and compacting the formwork cloth, thereby significantly improving the quality and efficiency of pasting the formwork cloth.
