Problems solved by technology

However, when this kind of hollow formwork is pre-processed in the factory, it still takes a lot of time to complete the assembly of the mold to cast this hollow formwork, especially the assembly of the cross-hole mold core, which is manually constructed, with low production efficiency and poor quality.

specific Embodiment 1

[0033] Specific embodiment 1: as Figure 1-5 As shown, this embodiment provides a pouring formwork for prefabricated hollow reinforced concrete with intersecting holes inside. The intersecting holes of reinforced concrete are formed by crossing several transverse core holes and several longitudinal core holes, including forming cavities for forming reinforced concrete , there are several longitudinal core tubes 1 uniformly distributed longitudinally in the molding cavity for forming longitudinal core holes, and several movable transverse core tubes 2 are telescopically installed in each longitudinal core tube 1, and the movable transverse core tubes 2 The length direction of the longitudinal core tube 1 is perpendicular to the length direction of the longitudinal core tube 1, and the movable transverse core tubes 2 on each longitudinal core tube 1 are arranged in one-to-one correspondence and the length of the movable transverse core tube 2 is the same as the distance between t...

specific Embodiment 2

[0042] Specific embodiment 2: the present embodiment provides a kind of using method of pouring formwork, comprises the following steps:

[0043] (1) Insert the positioning posts 12 on the front side plate 5, rear side plate 6, left side plate 7 and right side plate 8 into the positioning holes 13 of the bottom frame 4, and at the same time, the left side plate 7 and the right side plate 8 snap Insert the pin into the I-shaped connector 14 of the front side plate 5 and the rear side plate 6, then insert the latch into the eccentric sleeve 16 of the left side plate 7 and the right side plate 8, turn the handle to lock it quickly, and then place the supporting plate 15 On the bottom frame 4, a molding cavity is formed;

[0044] (2) Laying steel bars in the forming cavity, after laying, the longitudinal core tube 1 is inserted into the forming cavity from the core hole, and the plectrums 104 at both ends of the longitudinal core tube 1 expose the core tube cavity 103;

Abstract

The invention provides a prefabricated hollow reinforced concrete pouring formwork with cross holes inside. The pouring formwork comprises a forming cavity used for forming reinforced concrete; a plurality of longitudinal core tubes used for forming longitudinal core holes are evenly distributed in the forming cavity longitudinally; a plurality of movable transverse core tubes used for forming transverse core holes are telescopically installed in each longitudinal core tube; the length of each movable transverse core tube is adapted to the distance between every two adjacent longitudinal coretubes, and the length direction of each movable transverse core tube is perpendicular to that of each longitudinal core tube; and the pouring formwork further comprises core tube retracting and protruding mechanisms used for driving the movable core tubes to move in a direction perpendicular to the length direction of the longitudinal core tubes. According to the pouring formwork, a hollow formwork is prefabricated in a factory, so that site construction efficiency is effectively increased; and moreover, the pouring formwork is simple in structure, convenient to operate and high in operation efficiency, and can greatly shorten factory prefabrication time.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a pouring formwork for prefabricated hollow reinforced concrete with intersecting holes and a method for using the same. Background technique [0002] In the existing building construction, formwork is usually installed first, and then concrete is poured on-site between the formwork to form a wall, and the above-mentioned formwork is removed after the wall reaches a certain strength requirement. The construction method has many procedures, long construction period, huge workload of on-site assembling and dismantling formwork, and a considerable part of the dismantled formwork cannot be reused many times, resulting in waste of materials. [0003] Chinese Patent No. CN102581939A provides a prefabricated reinforced concrete hollow formwork with intersecting holes and its vertical formwork forming equipment. There are vertical and horizontal interpenetrating channels in it, so o...
