Die for production of three-row-hole recycled concrete

Abstract

The invention discloses a die for the production of three-row-hole recycled concrete, comprising an upper die and a lower die, wherein the lower die is internally provided with three identical die cores between every two of which a partition is arranged, the partitions lead each die core to be independent from each other, three rows of hole dies are uniformly arranged in each die core, every row of the hole dies are serially connected through rods and fixed at the inner wall of the lower die through the rods, pores between the hole dies and the inner wall of the lower die and gaps between the hole dies and the partitions of the mould cores are used for forming walls of a building block, gap between every two of the hole dies is used for forming ribs of the building block. An upper end horizontal plate is arranged around the upper end of the lower die, a lower end horizontal plate is arranged around the lower end of the lower die, the lower end horizontal plate is used for fixing the lower die on a vibrating platform of a block machine, a vertical plate is arranged above three sides of the upper end horizontal plate, a plurality of supporting plates are arranged between the lower end horizontal plate and the upper end horizontal plate, and the supporting plates are vertical to an upper end horizontal plane and a lower end horizontal plane. The die greatly improves the intensity grade of the recycled concrete-made building block and expands the applicable scope of the recycled construction wastes.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a mold device, in particular to a mold for producing recycled concrete blocks with three rows of holes. Background technique [0002] With the continuous acceleration of the urbanization process in our country, more and more construction wastes are produced in the urban construction, especially the reconstruction of urban villages produces a large amount of construction waste. my country is also a country prone to natural disasters. The earthquake caused a large number of houses to collapse, and the demolition of dilapidated houses after the earthquake all produced a large amount of construction waste. If these construction wastes cannot be reused as resources, they will not only pollute the environment but also occupy a large amount of landfill sites. [0003] The recycling rate of construction waste in foreign countries is very high. For example, the recycling rate of t...

Problems solved by technology

At present, conventional standard concrete block molds are usually used to produce recycled concrete blocks, such as the patent application No. 200920032812.9 filed by the applicant in 2009, which discloses a production mold for recycled concrete blocks. Including the mold box and the two mold cores arranged symmetrically inside the mold box, the strength of the blocks produced by it can only reach the strength level of MU5.0, and a large amount of natural aggregate needs to be mixed in, and the utilization rate of recycled aggregate is not high , if it is all produced with recycled aggregates, since the strength of recycled concrete is lower than that of ordinary concrete, the strength of the single-row hole recycled concrete blocks produced is lower. These blocks can only be used for filling wall structures and cannot be used for load-bearing wall structure

The main reason is that ordinary concrete blocks have fewer rows of mold holes, larger hollow ratio, and relatively large mold compression. They are directly used to produce recycled concrete blocks, which cannot meet the requirements of the compressive strength level of load-bearing blocks.

Especially in masonry structures with seismic requirements, this limits the application range of recycled concrete blocks, which is not conducive to the further promotion and application of recycled concrete
