Description

Technical Field

[0001] The invention relates to the technical field of radiation shielding, in particular to a wedge-shaped splicing structure for preventing radiation penetration. Background Art

[0002] In the construction of radiation shielding, there are currently several main methods:

[0003] 1. Mix barite (barium sulfate) + cement + other auxiliary materials into concrete, and apply the plaster manually or mechanically. This method is difficult to master the thickness and density of the plaster, and the thickness cannot exceed 3cm each time. The shielding effect of X-rays is greatly affected by the proficiency of the construction workers.

[0004] 2. When barite (barium sulfate) bricks or other commercial bricks with shielding effects are stacked, barite (barium sulfate) mortar is required to fill and couple the bricks. During the filling and coupling process, the fullness of the mortar is difficult to standardize. The uneven water absorption of barite bricks to the mortar can easily cause cavities, thereby affecting the shielding effect of X-rays.

[0005] 3. The lead plates or barite (barium sulfate) plates overlap at the connecting parts. Although this method can achieve the shielding effect, it requires keel fixation and wastes materials.

[0006] Therefore, it is necessary to provide a device which is easy to assemble and can effectively shield X-rays. Summary of the invention

[0056] Embodiment 2:

[0057] like Figure 2 , Figure 4 , Figure 6 , Figure 8 , Fig.10 , Fig.12 , Fig.14 , Fig.16 , Fig.18 , Fig. 20 , Fig. 22 As shown, the content of this embodiment is substantially the same as that of the first embodiment, except that:

The materials with radiation shielding function include aluminum plate, barite, and cement. Different materials have different shielding effects, and the thickness of the wedge-shaped blocks made to achieve the same shielding effect is also different. The strength grade of the middle assembly block 1, the left top edge block 2, the left side block 3, the left bottom edge block 4, the bottom edge block 5, the right bottom edge block 6, the right side block 7, the right top edge block 8, and the top edge block 9 is not lower than MU20.

When in use, a left bottom edge block 4, several bottom edge blocks 5, and a right bottom edge block 6 are stacked together side by side and horizontally closely to form a base, and then multiple layers consisting of the left side blocks 3, The middle layer is composed of the middle assembly block 1 and the right side block 7, and the ridges and grooves between the upper and lower layers are matched and snapped together. The middle assembly blocks 1 in the multi-layer middle layer can be stacked vertically or stacked up and down (that is, the second groove 53, the tenth groove 13, and the fourth groove 91 are not on the same vertical line). Finally, the left top side block 2, the top side block 9, and the right top side block 8 are fixed above the middle layer to form a complete wall. The thickness of the wall can be determined according to the thickness of the middle assembly block 1. Multiple layers of walls can be laid side by side at the same time, and the splicing structure can be used to splice into a sealed space that can block radioactive rays to achieve a protective effect.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
