[0002] In many medical institutions or medical research institutions, radioactive treatments or experiments are often carried out, and radioactive reagents or medical equipment are stored and used. In order to avoid radioactive contamination, these areas and places need to be designed for radiation protection. Arranging radiation-proof walls is a common means of protection.

[0003] Existing radiation-proof walls are usually made up of multiple ordinary lead plates, which have poor structural stability and are prone to gaps, affecting the overall radiation-proof performance. Summary of the invention

The protective wall has a novel design, high structural stability, good radiation protection performance, and strong practicality.

[0007] Furthermore, a lead gasket is provided between the self-tapping screw and the barium sulfate plate to increase the contact area between the self-tapping screw and the barium sulfate plate, prevent the self-tapping screw from loosening freely, and protect the surface of the barium sulfate plate.

[0008] Furthermore, one end of the lead gasket bends outward and wraps around the head of the self-tapping screw, thereby protecting the head of the self-tapping screw from direct external impact, thereby not affecting subsequent disassembly. The method is simple and practical, and covers the gap at the connection between the self-tapping screw and the barium sulfate plate without affecting the overall radiation protection performance.

[0009] Furthermore, angle steel cross braces are provided between adjacent vertical purlins, which improves the connection strength of adjacent vertical purlins.

[0010] Furthermore, a barium sulfate radiation proof cement layer is provided between the protective wall body and the lower floor slab, which can play the role of leveling the ground. The barium sulfate radiation proof cement layer has the advantages of strong chemical inertness, good stability, acid and alkali resistance, high density, moderate hardness, and the ability to absorb harmful rays. At the same time, it is easy to construct and has a long service life.

[0011] Furthermore, a wooden pad is provided between the hollow square steel and the floor slab to prevent the hollow square steel from directly contacting the floor slab and causing extrusion damage, thereby protecting the floor slab.

[0012] Furthermore, the hollow square steel is welded and fixed to the vertical purlin, which is reliable and prevents the vertical purlin from displacement, thereby improving the installation stability of the vertical purlin.

[0013] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0014] 1. One end of the lead gasket bends outward and wraps around the head of the self-tapping screw, which protects the head of the self-tapping screw from direct external impact, thus not affecting subsequent disassembly. It is simple and practical, and covers the gap at the connection between the self-tapping screw and the barium sulfate plate, without affecting the overall radiation protection performance.

[0015] 2. Barium sulfate radiation-proof cement mortar is filled between adjacent barium sulfate boards, which not only improves the connection strength between adjacent barium sulfate boards, but also avoids the formation of gaps between adjacent barium sulfate boards without affecting the overall radiation protection performance.

[0016] 3. The connecting angle steel is pressed against the surface of the protective wall body. The connecting angle steel cooperates with the hollow square steel to clamp the protective wall body and the vertical keel. On the one hand, it prevents the protective wall body and the vertical keel from moving forward and backward, thereby improving the overall structural stability. On the other hand, it prevents the barium sulfate board from being detached from the vertical keel, thereby improving the installation reliability of the barium sulfate board.

DETAILED DESCRIPTION

[0023] like Figures 1 to 4 As shown, a medical protective wall of the utility model includes a protective wall body, a vertical keel 1 and a connecting angle steel. The protective wall body is made of a plurality of barium sulfate plates 2. The radiation protection performance of the barium sulfate plates 2 is better than that of ordinary lead plates. The vertical keel 1 adopts a hollow steel square tube, which meets the strength requirements while reducing the weight. The barium sulfate plates 2 are fixed to the vertical keels 1 by self-tapping screws 3, which are firmly fixed and quick to install.

[0024] A lead washer 4 is provided between the self-tapping screw 3 and the barium sulfate plate 2 to increase the contact area between the self-tapping screw 3 and the barium sulfate plate 2, prevent the self-tapping screw 3 from loosening freely, and protect the surface of the barium sulfate plate 2. One end of the lead washer 4 is bent outward and wraps around the head of the self-tapping screw 3, protecting the head of the self-tapping screw 3 from direct external impact, thereby not affecting subsequent disassembly, being simple and practical, and covering the gap at the connection between the self-tapping screw 3 and the barium sulfate plate 2, without affecting the overall radiation protection performance.

[0025] Barium sulfate radiation-proof cement mortar is filled between adjacent barium sulfate boards 2, which not only improves the connection strength between adjacent barium sulfate boards 2, but also avoids the generation of gaps between adjacent barium sulfate boards 2 without affecting the overall radiation-proof performance.

[0026] The back of the vertical purlin 1 is welded and fixed with a hollow square steel, which is reliably fixed to prevent the vertical purlin 1 from displacement, thereby improving the installation stability of the vertical purlin 1. The hollow square steel includes an upper hollow square steel 5 and a lower hollow square steel 6. The upper hollow square steel 5 is fixedly connected to the upper floor slab 7 by expansion bolts, and the lower hollow square steel 6 is fixedly connected to the lower floor slab 8 by expansion bolts. The fixing is firm and not easy to loosen freely. A wooden pad 9 is provided between the upper hollow square steel 5 and the upper floor slab 7, and between the lower hollow square steel 6 and the lower floor slab 8 to prevent the hollow square steel from directly contacting the floor slab and causing extrusion damage, thereby protecting the floor slab.

[0027] The connecting angle steel includes an upper connecting angle steel 10 and a lower connecting angle steel 11. The upper connecting angle steel 10 is fixedly connected to the upper floor slab 7 by expansion bolts, and the lower connecting angle steel 11 is fixedly connected to the lower floor slab 8 by expansion bolts. The connection angle steel is firmly fixed and is not easy to loosen freely.

[0028] The connecting angle steel is pressed against the surface of the protective wall body, and the connecting angle steel cooperates with the hollow square steel to clamp the protective wall body and the vertical purlin 1. On the one hand, it prevents the protective wall body and the vertical purlin 1 from being displaced forward and backward, thereby improving the overall structural stability. On the other hand, it prevents the barium sulfate board 2 from being detached from the vertical purlin 1, thereby improving the installation reliability of the barium sulfate board 2.

[0029] Angle steel cross braces 12 are provided between adjacent vertical purlins 1 and are welded and fixed to the back of the vertical purlins 1, thereby improving the connection strength of adjacent vertical purlins 1. Each vertical purlin 1 is connected as a whole to form a stable structural system that is not easy to fall apart freely and has reliable support.

[0030] A barium sulfate radiation-proof cement layer 13 is provided between the protective wall body and the lower floor 8. The area of ​​the barium sulfate radiation-proof cement layer 13 is larger than the cross-section of the protective wall body, and can play the role of leveling the ground. The barium sulfate radiation-proof cement layer 13 has the advantages of strong chemical inertness, good stability, acid and alkali resistance, high density, moderate hardness, and the ability to absorb harmful rays. At the same time, it is easy to construct and has a long service life.
