[0049] The installation and use process of the above-mentioned fixed mold is as follows:

[0050] S100: Determine the number and specifications of molds: Check the bridge deck reinforcement layout design drawing to determine the type, height, and maximum and minimum length and width of the reinforcement skeleton spacing. According to the type of reinforcement spacing, determine the specifications of the hanging plate component 300 to be used (for example, the positioning hole spacing is 150mm or 100mm). According to the side length of the reinforcement skeleton and the number of length and width reinforcements, determine the number of slider components 200 and hanging plate components 300 to be used and the size specification information of the track assembly 10 pedestal. The length of the single-side length and width base track 101 is the maximum length of the reinforcement skeleton side of this project.

[0051] S200: installing the track assembly 10: wherein the base track 101 does not need to be installed, and based on the construction drawing of the fixed steel bar skeleton, different movable tracks (such as the first movable track 112 and the second movable track 113) are selected and spliced ​​to form the movable track group 111.

[0052] S300: Install the slider assembly 20: First, align the slider component 200 on the base track 101, and align the dovetail groove at the bottom of the slider component 200 with the base track 101.

In actual construction, the largest steel cage is processed first. The slider group is installed with the maximum number for the first time, and then it can be removed and reduced in number later. The installation of the slider component 200 on the movable track group 111 is the same as the installation of the slider component 200 on the base track 101.

[0053] S400 : Installing the positioning structure 130 : After the slider member 200 on the base rail 101 is installed, the positioning structure 130 is installed on the end of the base rail 101 .

[0054] S500: Install the hanging piece assembly 30: After the installation of the slider component 200 is completed, the hanging piece component 300 can be installed, that is, the positioning hole structure 301 of the hanging piece component 300 is aligned with the hanging piece column 202 on the slider component 200. The hanging piece component 300 is used to fix the spacing between each slider component 200 to ensure that the internal tooth grooves of the tooth plate 205 on the top of the slider component 200 are consistent with the spacing between the longitudinal and transverse reinforcements inside the steel skeleton.

[0055] S600: Angle adjustment: When the special-shaped steel bar skeleton needs to be fixed, the angles of the track assembly 10 and the tooth plate 205 need to be adjusted; the angle adjustment of the track assembly 10 is achieved based on the connection unit 120 and the positioning unit, and the angle adjustment of the tooth plate 205 is mainly achieved by rotating the steering wheel body 203.
