Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a floor armor seam installation and fixing device and a construction method thereof. Background Art

[0002] At present, in order to reduce concrete cracks and improve the visual quality of the formed surface, most concrete floors widely use armor joints (i.e., separation joints) as floor separation measures. The main function of the armor joint is to provide a position for controlling cracks during the concrete hardening process, thereby avoiding the generation of disordered cracks and ensuring the overall beauty and structural stability of the floor; however, the armor joints are installed on site in sections, and the installation straightness is difficult to control, the installation accuracy is low, and the construction efficiency is not high, resulting in the armor joints on the final concrete floor being not straight, affecting the final visual effect.

[0003] In order to solve the above problems, the market is in urgent need of a new device or method that can improve the installation accuracy and straightness of the armor seam while ensuring the construction quality and efficiency, thereby improving the appearance of the final concrete floor.
