The middle stirrups need to be manually hooked on the lower prestressed steel rods; the structure of the I-shaped pile is irregular, and the existing I-shaped pile reinforcement is generally manually tied, which is labor-intensive and time-consuming; after the bending of each split steel bar, it is manually assembled and manually tied, which is labor-intensive and time-consuming, and it is easy to miss the binding points; therefore, a mold-assisted installation is needed to improve installation efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides an assembly mold and an assembly method for prestressed I-shaped piles, which have the advantage of high installation efficiency.

[0006] As a preferred solution of the present invention, a curved steel plate is provided on the base.

[0007] To implement the above technical solution, the arrangement of the curved steel plate not only meets the shape of the prefabricated components but also facilitates the placement of the steel rods, thereby improving the convenience of installation.

[0008] As a preferred solution of the present invention, the second side end plate and the base are connected by connecting rods, and the connecting rods are located on both sides of the second side end plate; a rotating screw is also provided between the connecting rods, and the rotating screw is threadedly connected to the second side end plate and the base respectively.

[0009] To implement the above technical solution, the second side end plate is movable, which makes it easy to adjust the distance between the second side end plate and the base and to install the steel rod.

[0010] As a preferred solution of the present invention, the perforated clamping member includes: a tensioning hole and a clamping groove corresponding to the tensioning hole, and the tensioning hole and the clamping groove are each provided with a plurality of groups, the tensioning hole is provided on the second side end plate, and the clamping groove is provided on the first side end plate.

[0011] To implement the above technical solution, the tensioning of the steel plate is achieved through the mutual cooperation between the tensioning holes and the reinforcement grooves, so as to facilitate the binding operation.

[0012] As a preferred solution of the present invention, the tensioning grooves are respectively opened on the first side end plate and the second side end plate, and the tensioning grooves are provided in two groups and are arranged in a U-shape.

[0013] To implement the above technical solution, the tensioning groove is set up to place the steel rod directly in the tensioning groove, which improves the convenience of placing the steel rod and avoids the traditional form of manually threading the steel rod, which is inefficient.

[0014] As a preferred solution of the present invention, the clamping member includes: two side molds, and a side mold connecting plate hinged to the two side molds, and the side mold connecting plate is fixedly arranged on both sides of the base.

[0015] To implement the above technical solution, the side formwork is set up and the steel bars are finally reinforced and compacted so as to achieve the binding of the steel bars.

[0016] As a preferred solution of the present invention, a clamping groove is provided in the side mold.

[0017] An assembly method for an assembly mold for a rod tendon bone includes the following assembly method:

[0018] (1) placing steel bars into the tensioning holes in sequence, limiting the forward movement of the steel bars in the tightening grooves, tensioning and locking the steel bars on one side of the tensioning holes by bolts; and placing the lower steel mesh fabricated in advance on the steel bars;

[0019] (2) After the installation of the lower steel bar is completed, the middle steel cage is preliminarily installed and placed directly in the tensioning groove (4) by a sling. After preliminary tensioning by manual labor, the two ends of the steel bar are fixed by bolts;

[0020] (3) After the middle steel cage is installed, repeat the installation method of (1) and place the pre-made upper steel mesh on the steel rod using a sling;

[0021] (4) Start the tensioners of the first side end plate (2) and the second side end plate (3) to perform final tensioning and fixing of the steel rods, and finally manually tie the locations that need to be tied.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The reinforcement is divided into three parts (upper, middle and lower), so that the three independent parts can be machine-processed and finally assembled. Manual work only needs to tie some fixed points, which improves efficiency.

[0024] This installation method forms a complete closed loop of stirrups, effectively reducing the theoretical crack width of the concrete component, thereby improving the crack resistance of the concrete component.

[0025] The placement efficiency of steel bars can be improved through the design of special molds and the setting of tensioning holes, thereby improving production efficiency and installation accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
