Pouring mold of precast pre-stressed concrete T-shaped beam

Abstract

The invention relates to a pouring mold of a precast pre-stressed concrete T-shaped beam, which comprises a left template, a right template, a bottom template and an end head baffle which constitute a T-shaped beam cavity, wherein the left template is fixed on a left template supporting frame, the right template is fixed on a right template supporting frame, the bottom template is fixed on a bottom template supporting frame, the left template supporting frame and the right template supporting frame are respectively coordinated on the bottom template supporting frame by sliding and located on left and right sides of the bottom template, a left template drive mechanism and a right template drive mechanism are fixed on the bottom template supporting frame, and the left template drive mechanism and the right template drive mechanism are connected respectively to the left template supporting frame and the right template supporting frame and are used to respectively drive motions of the left template supporting frame and the right template supporting frame so as to complete die assembly or die opening. The T-shaped beam produced by the pouring mold has a smooth surface and high quality, does not need die splicing or die removal, only needs simple operations such as the die assembly or the die opening, greatly reduces workers' labor strength, reduces operation time and has high production efficiency.

Description

technical field [0001] The invention relates to the production field of prestressed concrete T-shaped beams, in particular to a casting mold for prefabricated prestressed concrete T-shaped beams. Background technique [0002] Large-span prestressed concrete T-beams are required for floors or roofs of long-span buildings such as industrial plants, warehouses, auditoriums, exhibition halls, and sports rooms. Existing long-span prestressed concrete T-beams and prestressed concrete The templates used in the plate production are all produced on the steel frame by assembling small pieces of steel plates into the shape of T-shaped beams (plates). The assembly between the small steel plates and the small steel plates is realized by connecting fasteners such as fastening buckles, bolts or iron wires, so that there are gaps and unevenness between the small steel plates. There are also units that try to use larger steel plates for assembly. As a result, manpower cannot move and assemb...

AI Technical Summary

Problems solved by technology

The technology of small-piece steel formwork is very backward, and has the following disadvantages: 1) The surface of the produced T-beam (slab) is uneven and poor in quality; It is difficult to find workers; 3) It takes a lot of time to assemble and close the small steel formwork, the cycle is long, and the efficiency is low; 4) The small steel formwork is difficult to dismantle, the loss of the formwork is large, the spare parts are lost, the maintenance workload is heavy, and the cost is high
