Embodiment Construction

[0029] see figure 1 and image 3 , the prefabricated hollow beam folding and pulling steel inner mold system in this embodiment adopts a steel structure, and on the cross section of the inner mold, two half-mould units with opposite openings are arranged in a left and right split; each half-mould unit The upper unit plate 1 and the lower unit plate 2 are respectively hinged at the sides to form a hinge structure that can be expanded or folded up and down;

[0030] In each half-mould unit, tie rods 3 are arranged along the length direction of the inner mold, and the tie rods 3 are hinged with the upper unit plate 1 at the position of the top plate with a set of upper connecting rods 4 arranged at intervals, and a set of lower connecting rods arranged at intervals 5 is hinged with the lower unit plate 2 at the position of the bottom plate;

[0031] With the structure in this embodiment, the inner mold can have the following two states by operating the pull rod 3:

Abstract

The invention discloses a folding drawing steel internal mould system for a prefabricated hollow beam, which uses a steel structure and is provided with two semi-mould units with opposite openings at left and right sides on a cross section of the internal mould. The semi-mould unit is formed by an upper unit plate and a lower unit plate which are hinged at the side to form a hinge structure capable of unfolding or folding up and down. In the semi-mould unit, a pull rod is arranged along the length direction of the internal mould. The pull rod is hinged respectively with the upper plate unit at the top plate through a group of upper connecting rods arranged at intervals and hinged with the lower unit plate at the bottom plate through a group of lower connecting rods arranged at intervals. In the invention, the pull rod is drawn so that the internal mould is respectively in unfolding and folding states. The invention does not need to disassemble manually and is particular suitable for prefabricating hollow beams with small sections, and improves the work efficiency greatly.

Description

technical field [0001] The invention relates to a steel inner mold system for prefabricated hollow beams. Background technique [0002] The structural size of the internal mold of the prefabricated hollow beam depends on the structural size of the hollow beam itself. There are various structural dimensions of the hollow beam in practical applications. Take a 10m hollow beam as an example: the length of the hollow beam steel internal mold is 10.9m, and the width is 0.75m and a height of 0.36m, the existing internal mold forms have the following problems: [0003] An airbag-type inner mold, but it is easy to break and has a low turnover rate, and after the airbag is damaged, it needs a professional manufacturer to repair it, which is difficult and expensive to repair; the airbag-type inner mold has light weight, and the hollow beam is easy to prefabricate. Floating, the quality of the hollow beam is difficult to guarantee. [0004] A bamboo plywood type inner mold is compose...
