Technical Field
[0001] The utility model relates to the technical field of prefabricated beam ends, in particular to a prefabricated beam end template with a positioning device. Background Art
[0002] Precast beams refer to beams that are prefabricated in a factory and then transported to the construction site for installation and fixation in the position required by the design. The ends of precast beams play an important structural role in construction projects. Specifically, the ends of precast frame beams (or main beams) are the key parts for connecting precast columns, while the ends of precast beams (or secondary beams) are the parts connected to precast frame beams. When pouring the ends of precast beams, end formwork is usually used to ensure that the ends of the beams have the shape and dimensional accuracy required by the design. The precast beam end formwork is a formwork used to form the shape of the beam ends during the precast beam manufacturing process. It is an important part of precast beam manufacturing, and its design and manufacturing accuracy directly affect the quality and performance of the precast beams. The use of precast beam end formwork can significantly improve construction efficiency.
[0003] In the prior art, when pouring the end of a precast beam, the end form and the side form are usually fixed directly by bolts to achieve the connection between the end form and the side form. Since the end form and the side form cannot be well positioned when they are connected and installed, the side form is prone to tilting during installation, and then misalignment with the end form is prone to occur, which will reduce the quality of installation and affect the efficiency of pouring the precast beam end. Therefore, in order to solve the above problems, a precast beam end formwork with a positioning device is proposed. Utility Model Content

[0025] Furthermore, the positioning mechanism also includes a first connecting rod 28, which is fixedly connected to the inner surface of the support frame 1, and a second connecting rod 29 is fixedly connected to the inner surface of the support frame 1. Through the arrangement of the first connecting rod 28 and the second connecting rod 29, when the position of the side mold 11 is adjusted, the first connecting rod 28 can move on the inner side of the second connecting rod 29, thereby making the side molds 11 more stable.
[0026] Furthermore, the fixing rod 2 is in two groups and movably connected to the sleeve rod 23.

The operation of the motor 26 drives the rotating rod 24 to rotate, and the first conical teeth 25 will rotate under the action of the rotating rod 24, and then the second conical teeth 27 will drive the forward and reverse screws 22 to rotate, and the fixed block 21 will move under the action of the forward and reverse screws 22, so that the fixed rod 2 drives the support frame 1 to move accordingly, and then the fixed rod 2 moves on the surface of the sleeve rod 23, which can adjust the distance between the side molds 11. At the same time, the first connecting rod 28 will move on the inner side of the second connecting rod 29, which can adjust the positioning between the side molds 11, so as to facilitate the stable installation of the end mold 14 and the side mold 11;
