Grouting molding mechanism for neutron anti-radiation multilayer concrete blocks

Abstract

The invention relates to a grouting molding mechanism for neutron anti-radiation multilayer concrete blocks. The mechanism comprises four side templates arranged on a frame and surrounding a frame; movable mold pressing devices are matched on the upper and lower sides of the molding frame consisting of the four side templates; the side templates are provided with grouting grooves for molding threeconcrete layers; pulp outlets of the grouting grooves are higher than the heights of the corresponding concrete layers; positioning lifting blocks are arranged at the upper parts of the side templates, and are provided with grouting grooves in butt joint with the grouting grooves in the side templates; the upper parts of the grouting grooves are connected with grouting joints; the positioning lifting blocks are connected to positioning lifting handrails arranged on the frame; the movable mold pressing devices at the upper part are arranged at the lower parts of the positioning lifting blocks;and the movable mold pressing devices at the lower part are arranged on the frame at the lower part. Grouting ports are formed in the side templates without interfering with leveled parts of the concrete layers; and meanwhile, low grouting height of each concrete layer can be guaranteed, so that smashing of the leveled concrete layers can be prevented.

Description

technical field [0001] The invention relates to the field of neutron radiation protection, in particular to a grouting forming mechanism for a neutron radiation protection multilayer concrete block. Background technique [0002] Neutron science is a high-tech discipline, which reflects the technological level of a country. Neutron science research includes many contents, such as neutron collisions, fusion, etc. Most neutron science research is accompanied by and radiation. Concrete blocks are generally used in radiation protection. In order to adapt to different penetrating radiation substances, it is more economical and practical to use three layers of concrete with different sand sizes for concrete blocks. Most of the concrete blocks are formed by formwork. The existing Concrete molding mechanisms mostly include four side formworks and a bottom formwork, and grouting is performed from the top of the four side formworks.

[0002] Neutron science is a high-tech discipline, which reflects the technological level of a country. Neutron science research includes many contents, such as neutron collisions, fusion, etc. Most neutron science research is accompanied by and radiation. Concrete blocks are generally used in radiation protection. In order to adapt to different penetrating radiation substances, it is more economical and practical to use three layers of concrete with different sand sizes for concrete blocks. Most of the concrete blocks are formed by formwork. The existing Concrete molding mechanisms mostly include four side formworks and a bottom formwork, and grouting is performed from the top of the four side formworks. The existing grouting method of this forming mechanism has relatively large defects for the molding of three-layer concrete blocks. When remolding, each layer needs to be troweled. This kind of upper grouting will interfere with the troweling. At the same time, the height of the upper grouting is relatively large, and it is easy to smash the lower concrete layer that has been smoothed, resulting in the formation of the whole.
