Description

Technical Field

[0001] The invention relates to the field of construction of ultra-thick radiation-proof steel plates for buildings, and in particular to an installation method and an installation device for an ultra-thick radiation-proof iron block wall. Background Art

[0002] With the rapid development of heavy ion technology in the medical field, the radioactive contamination and radiation damage caused by it can no longer be ignored. It is difficult for people to perceive the radiation around them, but in fact, radiation is everywhere. In specialized hospitals for heavy ion tumor treatment, heavy ion treatment involves a large amount of ion radiation. In order to prevent the leakage of ion radiation during treatment, ultra-thick steel plate radiation protection structures are designed in the walls of the heavy ion area. Since the volume and tonnage of the ultra-thick steel plates installed in such radiation-proof walls are generally large, the ultra-thick steel plates are generally composed of three groups of large steel plates with different cross-sections that are tightly fitted together (all 17.69m long, 0.5m thick, 4m, 5m, and 8.5m high; a total of 1215t, see below for details). Figure 1 and Figure 2 ). Therefore, the installation of steel plates in this type of radiation wall has the following difficulties: 1. There are very few steel plates with a thickness of more than 5 cm in the existing market, and the construction is limited by the common steel plate specifications in the existing market; 2. The installation volume is large, and it can only be reasonably split for the convenience of lifting and transportation; 3. In order to meet the radiation protection requirements during the decomposition construction, it is necessary to ensure that there are no splicing seams; 4. The combined installation standard requirements are high, and the overall verticality and horizontality after splicing, and the size of the splicing gap must be controlled reasonably; 5. It needs to be reliable and feasible, and the corresponding construction efficiency must be guaranteed while ensuring the stability, firmness, and radiation protection of the steel plate assembly.

[0041] The positioning base structure includes: a plurality of mutually parallel and spaced load-bearing square steels 3 are evenly arranged on a concrete base 1, a plurality of mutually parallel and spaced U-shaped channel steels 2 are arranged between the two ends of the load-bearing square steels 3, and the U-shaped channel steels 2 are perpendicular to the length direction of the load-bearing square steels 3.

[0042] Each stressed square steel 3 has screw holes with a diameter of 28 mm reserved at both ends, and the concrete base 1 is provided with corresponding through holes. The leveling nut 10 is first pre-placed on the upper end of the through hole of the concrete base 1, and then the stressed square steel 3 is placed so that its screw holes are aligned with the through holes, and the leveling bolts 4 are passed through the screw holes and the leveling nuts 10 to position the stressed square steel 3 on the concrete base 1. The leveling bolts 4 are screwed to move the leveling nuts 10 to adjust the horizontality of the stressed square steel 3 so that all stressed square steels 3 are at the same level.

[0043] Then, multiple parallel U-shaped channel steels 2 are placed on the stressed square steel 3, with the opening of each U-shaped channel steel 2 facing upward. The internal groove width of the U-shaped channel steel 2 is equal to the thickness of the assembly steel plate 12 to be installed, and the spacing between adjacent U-shaped channel steels 2 is the thickness of two assembly steel plates 12. After the U-shaped channel steels 2 are arranged, they are fixed to the stressed square steel 3 by welding.

(3) The steel plate (12) to be leveled is attached to one side of the leveling base surface, the horizontal seams of the steel plate (12) to be leveled and the assembly steel plate (12) on the leveling base surface are arranged in a staggered manner, L-shaped wedge plates (14) are arranged at intervals along at least two edges of the steel plate (12) to be leveled, one end of the wedge plate (14) is welded to the leveling base surface, a wedge block (16) is embedded between the other end of the wedge plate (14) and the leveling base surface, and the gap between the steel plate (12) to be leveled and the leveling base surface is squeezed from all sides of the steel plate (12) to be leveled, so as to adjust the levelness of the steel plate (12) to be leveled; (4) After the leveling assembly steel plate (12) is leveled, the spot welding points between the wedge plates (14) on the left and right sides and the leveling base surface are removed, and a force-bearing push ear (17) separated from the wedge plate (14) is welded on the surface close to the upper side thereof, and a hydraulic jack (18) is installed between the wedge plate (14) and the force-bearing push ear (17), and the hydraulic jack (18) is extended to push the leveled assembly steel plate (12) to move horizontally, so that the left and right edges of the leveled assembly steel plate (12) are offset from the vertical seam of the assembly steel plate (12) in the leveling base surface; (5) The translated assembled steel plate (12) is then welded to the leveling base surface and the surrounding wedge plates 14 are removed; (6) Then repeat the above steps (3) to (5), install other assembly steel plates (12) around the assembly steel plate (12) fixed in step (5), and finally weld the adjacent assembly steel plates (12) with grooves by short welds (15) until the iron block wall formed by laminating multiple layers of assembly steel plates (12) in sequence on the leveling base surface in step (2) reaches the designed thickness. (7) hoisting the assembled steel plate (12) to the upper end of the iron block wall obtained in step (6), raising and leveling the base surface according to steps (1) to (2), and then increasing the thickness of the raised and leveled base surface to the same as that of the iron block wall in steps (3) to (7); (8) Repeat step (7) until the iron wall reaches the designed height.

7. The method for installing the super-thick radiation-proof iron block wall according to claim 6 is characterized in that: The assembly steel plate (12) and the assembly steel plates (12) adjacent to it, above, below, left and right, are provided with grooves and protrusions extending along the side length and matching with each other on the end faces facing each other.

8. The method for installing the super-thick radiation-proof iron block wall according to claim 6 is characterized in that: The iron block wall adopts a layered staggered layout, and the assembled steel plate (12) is reasonably divided so that the assembled steel plate (12) has two thicknesses, and each thickness has two sizes; when the assembled steel plate (12) is 4 cm thick, there are two types of sizes, size one: 4 cm thick, 2.0 m wide, and 4.0 m long, size two: 4 cm thick, 2.5 m wide, and 4.5 m long; when the steel plate material is 2 cm thick, there are also two types of sizes, size three: 2 cm thick, 2.0 m wide, and 4.0 m long, size four: 2 cm thick, 2.5 m wide, and 4.5 m long. The horizontal seams of the front and rear assembled steel plates (12) that are attached to each other are staggered, and the length is determined according to the staggered seams, so that the left and right sides are also staggered, and the staggered seams are not less than 50 cm; the top surface thickness of the convex ribs is 4 cm, and the spacing between the convex ribs is 8 cm.

9. The method for installing the super-thick radiation-proof iron block wall according to claim 6, characterized in that: The wedge plate (14) is spot welded to the leveling base surface; all welding points need to be polished after removal, the wedge block (16) is made of a triangular steel block with a thickness of 2 cm, and the force-bearing push ear (17) is made of a rectangular steel plate with a width of not less than 2 cm.
