detailed description

The following examples illustrate possible implementations of the utility model, but they are not intended to limit the scope of protection of the utility model, and are described in advance.

As shown in Figures 1 to 4, the utility model provides a PC track beam mold, including an outer mold and a core mold 5 (shown in Figures 3 and 4), and the outer mold includes a bottom mold 1, a side mold 2 and an end mold 3. The bottom form 1, the side form 2 and the end form 3 form a pouring space, and the core form 5 is located in the pouring space. For example, the end form includes several rectangular plates connected end to end, and the two sides of the rectangular plate The ends are trapezoidal plates.

The bottom mold 1 includes a bottom frame 11 and a bottom template 12 above the bottom frame 11, and the upper surface of the bottom template 12 is an upwardly convex curved surface.

The side form 2 includes a bracket 21 and a side form 22, which are connected by a horizontal adjusting screw 23, and the adjusting screw 23 is provided with an adjusting nut to adjust the distance between the two. Two side templates 22 are respectively arranged on the two sides of the bottom template 12 and are located on the chassis 11, two end molds 3 are respectively arranged at both ends of the bottom template 12 and are located between the two side templates 22, and the end molds 3 and The side templates 22 are connected by tapered positioning bolts. The bottom of the bracket 21 is fixed on the bottom frame 11 , and the bottom of the side formwork 22 is provided with rollers 24 to roll on the bottom frame 11 to reduce the resistance when the side formwork 2 moves laterally. The roller 24 is provided with an adjusting screw rod, which can adjust the upper and lower heights of the side formwork 22. The side templates 22 of the two side molds 2 are fixedly connected by tie rods 4 .

In order to speed up the track beam prefabrication production speed of the construction party, one set of bottom formwork can be added, that is, one set of side formwork is matched with two sets of bottom formwork. In this way, after a product is completed, the adjusting screw 23 between the side formwork 22 and the support 21 is removed, and the support 21 is separated from the bottom frame 12, so that the side form 2 can be dismantled as a whole and moved to another bottom form 1. .

Specifically, the bracket 21 of the present utility model is a rectangular frame, including a cross bar 211 and an oblique bar 212. A platform 213 is provided on the top of the bracket 21 for construction personnel to walk on the top surface of the bracket. In addition, a ladder is provided on the bracket to lead to the platform. In order to ensure the safety of construction personnel, guardrails 214 are provided on the outside of the bracket 21 .
