Problems solved by technology

During pouring, the splicing joints between the modules are very easy to run out of pulp and fibers. After hardening, the concrete has high strength and strong bonding force with the mold, which increases the difficulty of demoulding and the probability of wear and deformation of the mold. In addition, the product requires high precision. The inner diameter and depth are within the range of 1000mm, the error is ±2mm, the flatness of the lid surface is within the range of 200mm, not exceeding 3mm, and the seam between the modules is less than 0.2mm, which increases the difficulty of mold processing

Embodiment 1

[0050] Embodiment 1: A steel pouring mold for a concrete barrel-shaped container, including a barrel body mold and a barrel lid mold, the barrel body mold includes an inner mold 1, an outer mold 2, and a base 3 for fixing the inner and outer molds (1, 2), The space between the inner and outer molds (1, 2) and the base 3 forms the mold cavity. The inner mold 1 is composed of a wall mold 1.1 and a top plate 1.2. The wall mold 1.1 is an inner mold composed of four arc-shaped modules 1.1.1. The cylinder body, the splicing seam 1.1.2 between the adjacent arc-shaped modules 1.1.1 is a crease line seam, and the arc-shaped modules 1.1.1 of the inner mold are set into two groups of symmetrical large blocks and small blocks, each group There are two pieces, the small arc-shaped module 1.1.1b and the adjacent large arc-shaped module 1.1.1a splicing seam are inner splayed fold line seams, which is convenient for the small arc-shaped module to come out first. The top plate 1.2 is covered o...

Embodiment 2

[0054] Embodiment 2: a kind of assembly method of concrete barrel-shaped container steel pouring mold, comprises the following steps:

[0055] 1. Barrel mold assembly steps:

[0056] (1) Put the inner mold 1 on the base 3, and initially fix the ears 4 on the four arc-shaped modules 1.1.1 with bolts, and adjust the size of the seam 1.1.2 between the two groups until the circle The forming cylinders between the arc-shaped modules 1.1.1 are consistent, and the connecting bolts are tightened;

[0057] (2) Fix the lifting ring in the bolt hole of the top plate 1.2, cover the top plate on the top of the inner mold 1 through the lifting ring, then remove the lifting ring, and cover the panel 5;

[0058] (3) Place the arc-shaped modules of the outer mold 2 on the working platform respectively, use bolts to connect the ears 4 on the arc-shaped modules 2.1 of the outer mold 2 to each other and initially fix them with bolts, and put the prefabricated lifting reinforcing steel ring 7 int...

Embodiment 3

[0067] Embodiment 3: a kind of dismantling method of concrete barrel-shaped container steel pouring mold, comprises the following steps:

[0068] 1. Barrel mold disassembly:

[0069] (1) Remove the connecting bolts on the corresponding lugs of the outer mold 2 and the base 3, lift the outer mold 2 by turning over the lug 6, and remove the base 3;

[0070] (2) Turn over the lifting lug 6 by 90°, place the mold horizontally, and remove the connecting bolts between the four arc-shaped modules 1.1.1 of the inner mold 1;

[0071] (3) Flip the lifting lug 6, and then turn it 90°, turn the mold upside down, and unload the two small arc-shaped modules 1.1.1b of the inner mold 1 inward;

[0072] (4) Use the same method to remove the two large arc-shaped modules 1.1.1a of the inner mold 1;

[0073] (5) Unload the top plate 1.2 by screwing the lifting ring into the bolt hole 1.2.1 of the top plate 1.2;

[0074] (6) Remove the connecting bolts between the positioning bolts 8 of the pre...

Abstract

The invention discloses a steel pouring mould for a concrete barrel-shaped container and assembly and disassembly methods. The steel pouring mould comprises a barrel body mould and a barrel cover mould, wherein the barrel body mould comprises an inner mould, an outer mould and a base used for fixing the inner mould and the outer mould; a mould cavity is formed by a space among the inner mould, the outer mould and the base; the inner mould consists of a wall mould and a top plate; the wall mould is a barrel body which is spliced by at least four arc-shaped templates; the top plate covers the top end of the wall mould; the outer mould is an outer barrel body which is spliced by at least two arc-shaped templates; the mould cover mould comprises an outer mould, inserts and a base; the outer mould is a barrel body which is spliced by at least two arc-shaped templates; an insert groove is formed in the inner surface of each arc-shaped template; the inserts are embedded in the insert grooves; the outer mould is fixedly connected to the base; assembly of the barrel body mould is characterized in that the plurality of arc-shaped templates of the inner mould are separately arranged on the base sequentially and are spliced to form a barrel body; the top plate covers the top end of the wall mould; and the plurality of arc-shaped outer mould templates are spliced to form an outer barrel body and then are fixedly connected with the base.

Description

technical field [0001] The invention is used for pouring the radioactive waste concrete disposal container. Background technique [0002] According to the retrieval, there are no similar patents and documents related to concrete container pouring steel molds. There is a common steel mold for pouring circular pipe culverts. Since the poured box culvert is a box-shaped pipe joint without a bottom, there is no bucket bottom forming module in the pouring mold; the circular pipe culvert is used to construct a water-repellent culvert. There is no precision requirement, and the material used is ordinary concrete with relatively low strength. To sum up, the circular pipe culvert steel form is far from the patent pouring steel form in terms of pouring products, dimensional accuracy, and concrete properties. Container raw materials include cement, aggregates, admixtures, reinforcement materials (steel fiber, carbon fiber, etc.), chemical admixtures and mixing water, etc. During...
