Description

[0002] In construction engineering, the installation quality of column formwork plays a crucial role in the stability and appearance of the entire concrete structure. Traditional column formwork installation and positioning rely heavily on manual experience, using tape measures, plummet, and other simple tools for measurement and calibration. This approach has many drawbacks: first, manual measurement has large errors, making it difficult to ensure the positional consistency and perpendicularity between multiple columns, which can lead to problems such as column displacement and tilting after forming, affecting the stability of the overall building structure; second, the operation process is tedious and inefficient, requiring a large amount of manpower and time; third, for some complex building layouts or high columns, traditional methods cannot meet the high-precision positioning requirements, increasing construction difficulty and quality risks. Therefore, there is an urgent need for formwork installation and positioning tools (such as the positioning card in this scheme) to solve these problems.

[0003] The novel column formwork positioning card designed in this scheme has a metal main body in L-shaped structure, providing positioning for the formwork around the concrete column;

[0004] In the design, attempts have been made to bend the metal into an L-shaped structure, but in actual use, it has been found that the placement position of the positioning card needs to be adjusted according to the different shapes of the concrete column, such as polygons and trapezoids, and there is a lack of angle measurement structure between adjacent positioning cards, which requires the use of additional angle measurement tools for placement and positioning. When facing trapezoidal structure columns, the bending angle of the L-shaped structure needs to be reconfigured, so a large number of positioning cards are required.

[0005] Therefore, after several improvements, the positioning card bent into an L-shaped structure is gradually changed into a split-type positioning card with angle adjustment function. INVENTION CONTENTS
