The utility model discloses a through-wall sealing connection structure of a flexible waterproof sleeve. The through-wall sealing connection structure comprises a flange sleeve, a flange gland, a first limiting ring, a second limiting ring and an air bag sealing ring. The flange sleeve is pre-embedded in a building wall, and a first limiting ring and a second limiting ring are fixedly arranged on the inner wall of the flange sleeve respectively and limit radial displacement of a pipe path. When the air bag sealing ring is inflated, the outer ring abuts against the inner wall face of the flange sleeve, the inner ring abuts against the periphery of the pipeline, the front end abuts against the rear end of the flange gland, and the rear end abuts against the front end of the first limiting ring, so that plugging and sealing are conducted. According to the sealing connection structure, the rear end of the flange gland and the front end of the first limiting ring are used for limiting, displacement of the air bag sealing ring is avoided, meanwhile, the air bag sealing ring is deflated when a pipeline is mounted and dismounted, the inner ring of the air bag sealing ring is separated from the pipeline, friction force between the air bag sealing ring and the pipeline is greatly reduced, and the risk of abrasion of the air bag sealing ring is reduced; therefore, the pipeline is convenient to mount and dismount.

The invention relates to a blade maintenance tool which comprises a base. The transfer frame is arranged on the base; the maintenance assembly is connected with the transfer frame, extends in the first direction and comprises a maintenance cabin; the maintenance assembly has a moving freedom degree relative to the adapter frame in at least one of the first direction and the second direction intersecting with the first direction. According to the blade maintenance tool provided by the embodiment of the invention, the blade maintenance tool can be used for supporting the maintenance personnel to the to-be-maintained area of the blade, so that the safety of the maintenance personnel is ensured.

The invention discloses a large-span annular cantilever steel plate anti-deformation construction structure and method. The large-span annular cantilever steel plate anti-deformation construction structure comprises a lifting mechanism, a supporting mechanism and an embedded part, wherein the upper portion of the lifting mechanism is used for lifting a transfer room cantilever steel plate; the middle portion of the supporting mechanism is used for supporting the lifting mechanism; the lifting mechanism comprises a first steel box beam, a second steel box beam, a hanging beam and a connecting beam; the first steel box girder and the second steel box girder are arranged side by side and connected through a plurality of hanging beams and a plurality of connecting beams, the hanging beams are arranged at the lifting positions of the transfer room cantilever steel plates, and the connecting beams are arranged on the two sides of the hanging beams. A connecting steel plate is installed on the lower portion of the hanging beam, a plurality of hanging rods are installed on the connecting steel plate, and a transfer room overhanging steel plate is welded and fixed to the bottoms of the hanging rods. The supporting mechanism comprises a first supporting stand column used for supporting the first steel box girder and a second supporting stand column used for supporting the second steel box girder. The bottom of the supporting mechanism is installed on the embedded part. According to the scheme, construction is convenient, the construction precision and efficiency can be improved, and the construction risk is reduced.

The invention discloses an assembly type energy-saving composite interior wall structure and an assembly method thereof, and relates to the technical field of building components, the structure comprises a plate, the upper surface of the plate abuts against a fixed rail, the fixed rail is fixedly connected with a roof through nails, and a rubber plate is installed at the joint of the upper surface of the fixed rail and the roof; every two adjacent plates are clamped with each other, and the joint of the two plates is coated with an adhesive; a waterproof layer is bonded on the board surface of the board, and a facing layer is bonded on the outer side surface of the waterproof layer; the assembly method comprises the following steps: S1, paying off; s2, mounting a fixed rail; s3, the plates are installed; s4, mortar is poured at the bottom; s5, a second plate is installed, and the steps S3 to S4 are repeated; s6, a fastening plate is installed; s7, mounting a wire pipe; s8, mounting a sealing plate; and S9, a waterproof layer and a facing layer are sequentially installed on the plate. According to the assembly type energy-saving composite inner wall structure and the assembly method thereof, the stability and firmness of connection between the plates are guaranteed, and construction is convenient.

The utility model relates to the technical field of flange gaskets, in particular to a flange gasket with high frictional resistance. The high-friction-resistance flange gasket is suitable for locking a large-specification flange, and the friction resistance is increased by improving the roughness of a contact surface. The flange gasket is formed by vulcanizing eight flange gasket sections in a surrounding manner; linear protrusions are arranged on the two sides of the top surface of the flange gasket section in the radial direction, and three sets of hexagonal protrusions are evenly distributed between the linear protrusions on the two sides and located in the circumferential direction of the top surface of the flange gasket section. When adjacent flange pad sections are in butt joint, the side surfaces of every two adjacent linear protrusions are connected and vulcanized into a whole. A frosted layer is arranged on the top surface of the hexagonal protrusion. Due to the hexagonal structure on the surface, the stress part of the locking mechanism can be increased, the convex patterns deform, and high normal pressure can be generated; and the roughness of the contact surface can be greatly improved through surface frosted treatment.
