The invention relates to the technical field of tent film construction, and provides an emergency rapid deployment tent film structure system which comprises a tensioning rod which is located between at least two supporting frames and rotates, a tent film is wound through rotation of the tensioning rod, tensioning of the tent film is achieved, the tensioning rod is in a cam shape, and the tensioning rod is connected with the supporting frames. Rotation between the upper inserting plate and the lower inserting plate is achieved through rotation of the tensioning rod, the upper inserting plate and the lower inserting plate are located on one side of the top of the supporting frame to rotate, a torsional spring is arranged at the transmission position, an inserting assembly is arranged at the end, making contact with the lower inserting plate, of the upper inserting plate, and the upper inserting plate is located between the tensioning rod and the lower inserting plate. By integrating a linkage structure, the construction process is simplified, and a single person can perform rapid deployment; the tensioning force and the clamping force are synchronously enhanced, and fixation is reliable; the upper inserting plate and the lower inserting plate are butted to block rain and snow, and sealing performance is improved; the structure meets the rainproof requirement, disassembly and assembly are convenient, and the use and maintenance cost is reduced.

The application discloses a roof integrated waterproof concealed deformation joint construction device and a construction method, and belongs to the field of deformation joint construction. The device comprises a first embedded strip arranged on the inner side wall of one side of the deformation joint, a second embedded strip arranged on the inner side wall of the other side of the deformation joint, and a waterproof assembly arranged between the first embedded strip and the second embedded strip. The waterproof assembly comprises a mounting plate arranged between the first embedded strip and the second embedded strip, and waterproof belts arranged on both sides of the mounting plate. A first moving groove is formed in the first embedded strip for sliding cooperation with the mounting plate. A second moving groove is formed in the second embedded strip for sliding cooperation with the mounting plate. A locking assembly is arranged on the first embedded strip for fixing the mounting plate. A supporting assembly is arranged on the mounting plate for supporting the waterproof belts. The application has the effect of improving the waterproof effect of the roof.
