Forming mechanism for neutron radiation shielding concrete blocks

Abstract

The invention relates to a forming mechanism for neutron radiation shielding concrete blocks. The forming mechanism comprises four side formworks arranged on a machine frame, and a frame is defined bythe four side formworks. Movable pressing die devices are arranged on the upper side and the lower side of the forming frame, composed of the four side formworks, in a matched manner. Grouting grooves used for forming three concrete layers are formed in each side formwork. Slurry outlets of the grouting grooves are higher than the corresponding concrete layers. A positioning lifting block is arranged on the upper portion of each side formwork. Grouting grooves connected with the grouting grooves in the corresponding side formwork in a butt joint manner are formed in each positioning lifting block. The upper portion of each grouting groove is connected with a grouting connector. The positioning lifting blocks are connected to positioning lifting pull rods arranged on the machine frame. Themovable pressing die device on the upper portion is arranged on the lower portions of the positioning lifting blocks, and the movable pressing die device on the lower portion is arranged on the lowerportion of the machine frame. According to the forming mechanism, grouting openings are formed in the side formworks, interference with smoothed parts of the concrete layers cannot be caused; and meanwhile it can be ensured that the grouting height of concrete on each layer cannot be too large, and therefore it can be avoided that the smoothed concrete layers are smashed.

[0006] 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.
