A kind of mechanized bolt fastening device for narrow space assembled building module and its using method, comprising: spanner chassis, the top of spanner chassis is fixedly installed with inverted L frame, first gear is rotated by reduction drive assembly, then the first gear of rotation synchronously drives first transmission rod and first rocker at the bottom of first transmission rod, so that transmission rod produces swing, then the transmission rod of swing is driven again in the action of first limiting rod, second limiting rod and sliding groove, drives ratchet spanner and spanner sleeve to move in 30 ° active range and continuously tightens bolt, so that the overall use of the device is light, meet in narrow range Construction, and can be translated and taken out, meet the functional requirements of once living of full renovation building, can achieve module building with hoist and install, improve connection efficiency, reduce operation time, shorten project construction period, greatly reduce on-site construction, improve overall assembly rate.

This utility model relates to the field of building decoration and discloses an elevated adjustable floor system, including a support plate, a panel on top of the support plate, and a bracket below the support plate for supporting the support plate. The panel is magnetically attached to the top surface of the support plate. The panel can be fixed to the top surface of the support plate by magnetic attachment, replacing the traditional leveling layer. This ensures a flat floor while enabling rapid installation and facilitates individual panel replacement, simplifying the process and avoiding wasted labor. Furthermore, the modular design allows for pre-processing of corresponding panels, reducing on-site construction and pollution, and significantly improving construction speed. The bracket and support plate are fixed by pins, requiring only plug-in assembly, making construction convenient and quick. This simplifies the process and reduces project costs.

The application relates to a circumferential sealing structure and construction method for a steel containment, and belongs to the technical field of nuclear power structure engineering. The structure comprises a steel containment and a peripheral shielding plant wall body, the steel containment is provided with a steel containment ring beam on the periphery, the shielding plant wall body is provided with a wall body ring beam on the inner side, the steel containment ring beam and the wall body ring beam are connected through a plurality of hinge type connecting pieces, the upper surfaces of the steel containment ring beam, the hinge type connecting pieces and the wall body ring beam are paved with continuous flexible sealing materials; the hinge type connecting pieces comprise a plurality of leaf pieces, the leaf pieces are connected through pin shafts, and the sum of the lengths of the leaf pieces is greater than the straight line distance between the steel containment ring beam and the wall body ring beam. The hinge type connecting pieces can adjust the shape through the rotation of the plurality of leaf pieces, deform together with the flexible sealing materials when the steel containment deforms, maintain the sealing effect of the upper space of the circumferential sealing structure under the condition that the steel containment deforms, and expand the contact area between the cooling water and the steel containment to the side wall of the steel containment.
