Die and process for producing ceramsite foamed precast concrete

Abstract

The invention discloses a die for producing ceramsite foamed precast concrete. The die comprises a top cover, a side template and a base plate which are arranged in the vertical direction in sequence, wherein the side template surrounds the top cover and the base plate and is connected with the top cover and the base plate, the top cover is provided with an overflow hole, and a residual grout pipe is connected to the upper side of the overflow hole; the inner diameter of the overflow hole is 3-5 cm, and the height of the overflow hole is 10-15 cm; a screen net is arranged at the position where the overflow hole is connected with the residual grout pipe, and the aperture of the screen net is smaller than the grain size of ceramsite; a grouting hole is formed in the base plate. The invention further provides a process for producing ceramsite foamed precast concrete. By the adoption of the die and process, a traditional method that mixing is conducted first and then grouting is conducted is replaced, grouting and mixing are conducted at the same time, ceramsite floating is prevented through pre-compacting and the blocking action of the top cover, so that ceramsite is distributed uniformly, ceramsite mixing amount is the largest, the heat insulation property and sound insulation property of the ceramsite foamed precast concrete are improved, and the overall quality of products is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a mold and a process for producing ceramsite foamed concrete prefabricated parts. Background technique [0002] Ceramsite has the characteristics of low density, light weight, heat preservation, heat insulation, excellent fire resistance, good shock resistance, excellent impermeability, alkali resistance and strong adaptability. Foamed concrete has light weight, good heat insulation performance, sound insulation Good fire resistance, good overall performance, good low elastic shock absorption, strong waterproof performance, good durability, convenient production and processing, good environmental performance and convenient construction. Therefore, in the field of construction, ceramsite and foamed concrete are usually used Combined together, it is made into ceramsite foamed concrete, which has exerted their respective advantages and improved the overall performance. [0003] In the trad...

Problems solved by technology

[0003] In the traditional solution, when making the prefabricated parts of ceramsite foamed concrete, the foamed concrete slurry and ceramsite are mixed and stirred first, and then poured into the mold. Usually, the stirred slurry is poured into the mold from above the mold. Because the density of ceramsite is often smaller than that of foamed concrete, the ceramsite floats up before the initial setting of the foamed concrete, resulting in uneven ceramsite foamed concrete, resulting in uneven thermal insulation performance and product quality. poor
