Abstract
The utility model relates to a structural design of a radioactivity shielding material, in particular to a shielding block structure used for shielding radioactive rays. When a radiation shielding wall is constructed, shielding blocks with certain structures are required to be overlapped to form a wall body, and a seam inevitably exists in the adjacent surface between two shielding blocks, which causes the problem of radioactive ray shielding penetration. The shielding block provided by the utility model adopts a hexahedron structure with cambered surfaces or triangular surfaces, and special structures of the cambered surfaces and the triangular surfaces are utilized to ensure that rays conducting rectilinear propagation can not propagate along the seam direction of the adjacent shielding blocks, so that the effective shielding thickness in the overlapping seam position is not reduced without increasing the size of the entire shielding blocks, the penetration problem in the overlapping seam positions of the shielding blocks is effectively solved, and the shielding material and the installation space are saved. The shielding block structure designed by the utility model can be used in solid shielding materials such as boron-containing paraffin, boron-containing polythene, lead, concrete, lead-boron polythene, etc.

Background technology
At present, build the alpha ray shield wall the time, the formation body of wall need overlap the shielding slab of a fixed structure, common shielding slab is square or rectangular parallelepiped, adopt flat mouthful of overlap joint, adjacent surface between shielding slab and the shielding slab certainly exists a slit, and effective shielding thickness herein is zero, the problem that just exists the radioactive ray shielding to run through.Usually solving the way that runs through at present is to introduce the ladder step at the adjacent surface of shielding slab, after adjacent surface is introduced step, forms the step shielding slab, adopts the step overlap joint, and effective shielding thickness maximum is located in the slit can increase by 50%.For this reason, in the higher occasion of shielding requirements, common solution is exactly with the whole thickening of the thickness of shielding material, runs through the weak link that seam brings to compensate for such.This shielding block structured defective is: directly caused the actual (real) thickness of shield must be more than or equal to 50% of its Design Theory thickness, and waste material not only, and need to take bigger installing space when mounted.
Summary of the invention
The purpose of this utility model is: provide a kind of cambered surface or triangular facet shielding slab structure that is used to shield radioactive ray, the problem that place, slit radioactive ray ran through when the shielding slab of this structure can effectively solve with shielding slab overlap joint barrier shield.
The utility model is achieved in that
A kind ofly be used to shield radioactive ray cambered surface or triangular facet shielding slab structure, it is characterized in that: the hexahedron structure of the structure of described shielding slab for forming by cambered surface and triangular facet.
Its supplementary features are:
Described cambered surface shielding slab has 6 faces, and wherein 4 faces are cambered surface, and other two faces are the plane.
Each cambered surface of described cambered surface shielding slab is contour cambered surface, and the height A of cambered surface is the arbitrary height greater than 5mm.
Described triangular facet shielding slab has 6 faces, and wherein 4 faces are triangular facet, and other two faces are the plane.
The angle of each triangular facet of described triangular facet shielding slab is identical, and the angle B of triangular facet is 165 ° to the maximum.
Effect of the present utility model is: because ray is rectilinear propagation, the structure of shielding slab is the hexahedron of cambered surface or triangular facet, utilize cambered surface and triangular facet its specific structure characteristics, guarantee that the ray of rectilinear propagation can not propagate according to the direction of adjacent shields piece seam, make that effective shielding thickness of seam crossing is almost constant between the adjacent shields piece, the physical dimension and the structure that have kept whole shielding body of wall simultaneously, when not increasing the bulk shielding wall size, solve the problem that shielding slab lap gap place is run through effectively, saved shielding material and installing space.

Embodiment
Shielding slab of the present utility model has cambered surface hexahedron and two kinds of structures of triangular facet hexahedron.
Cambered surface shielding slab structure is as shown in Figure 1: this cambered surface shielding slab has 6 faces, and wherein upper and lower, forward and backward 4 faces are cambered surface, and each cambered surface is contour cambered surface, and the height A of cambered surface is the arbitrary height greater than 5mm, and other left and right two faces are the plane.
