Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete structures, and more specifically to a prefabricated steel box with holes in a shielding and radiation-proof super-thick plate wall. Background Art

[0002] The prefabricated steel box with holes in the extra-thick plate wall for shielding and radiation protection is a special building structure. Its main use is in the construction of extra-thick concrete vertical structures. Specifically, this prefabricated steel box can replace the traditional method of leaving holes in wooden molds. It uses a positioning bracket at the bottom of the prefabricated steel box to fix the position of the steel box and ensure the accuracy of the position of the hole. This requires a prefabricated steel box with holes in the extra-thick plate wall for shielding and radiation protection.

[0003] After searching the existing published technical documents, the Chinese patent publication number CN203080780U fixes the position of the steel box by setting a positioning bracket at the bottom of the prefabricated steel box to ensure the accuracy of the position of the hole; the prefabricated steel box itself has its own rigidity, which is sufficient to withstand the pressure of concrete on it during the concrete pouring process, thereby ensuring the accuracy of the geometric dimensions of the hole; steel plate head plates are set at both ends of the prefabricated steel box to prevent concrete from flowing into the steel box during the concrete pouring process; the prefabricated steel box does not need to be dismantled, avoiding the problem that the wooden formwork in the hole cannot be dismantled in the traditional practice; however, the prefabricated steel box has the following defects:

[0004] When the prefabricated steel box is cast with holes in the shielding and radiation-proof extra-thick plate wall, although the two mouths of the prefabricated steel box can be encapsulated during the encapsulation and casting process, it is difficult to achieve vertical positioning and encapsulation of the prefabricated steel box during the encapsulation process. The encapsulation effect of the prefabricated steel box is poor, and it is very easy to cause the encapsulated part of the prefabricated steel box to fall off. For this purpose, a prefabricated steel box with holes in the shielding and radiation-proof extra-thick plate wall is provided. Utility Model Content
