The utility model relates to a kind of concrete structures, belong to concrete reinforcing and reinforcing technical field, specifically a kind of concrete reinforcing and reinforcing structure, including rectangular concrete column and floor, the rectangular concrete column is set at the top of floor, further include side face reinforcing assembly and top reinforcing assembly;U-shaped fastening frame, the U-shaped fastening frame is set on the surface of floor, the U-shaped fastening frame is set with a pair;The utility model reaches the effect that the construction efficiency is improved by assembly type installation, prolongs service life, solves the existing construction structure and needs pre-cutting limiting groove on the both sides of crack to accommodate limiting plate, cutting vibration can aggravate original crack expansion, slotting process can induce secondary cracking;And crack periphery concrete is often uneven, actual construction is difficult to guarantee the accurate embedding of groove and plate, possibly leading to the problem of invalid floating of reinforcing plate.

The utility model discloses a fire-retardant plugging auxiliary device for a hanging hole in a sleeve, relates to the technical field of building construction, and solves the problem that a template for plugging the hanging hole is inconvenient to support in the prior art. The device comprises a pair of plugging templates, wherein the two plugging templates are adjustably connected through a connecting structure; a plurality of traction hooks are distributed on the plugging template, and pull ropes are connected to the traction hooks respectively; semicircular grooves are formed in the opposite sides of the two plugging templates. According to the pipeline plugging device, the plugging templates are arranged and matched with the semicircular grooves, so that the pipeline plugging device can be clamped on a pipeline during use, the hook is arranged to be matched with the pull rope to pull from the position above the hanging hole during assembly, the two plugging templates are assembled and matched and fixed with the pipeline in cooperation with the connecting structure, and finally the plugging purpose is achieved; a support does not need to be arranged in the space below the hanging hole, the supporting difficulty and labor intensity in the installation process are lowered, and the requirement for the space below the hanging hole is lowered.

The utility model provides a sealing wet tissue cover capable of preventing microbial contamination, which belongs to the technical field of hygienic products and comprises a lower cover main body connected onto a wet tissue packaging bag, an upper cover main body matched with the lower cover main body and a hinge used for connecting the lower cover main body and the upper cover main body, and the lower cover main body is provided with an opening used for extracting wet tissues; an annular lower cover sealing ring is arranged at the edge of the opening; an upper cover outer sealing ring and an upper cover inner sealing ring which are matched with the lower cover sealing ring are arranged on the bottom surface of the upper cover main body; by arranging the sealing structure and the drainage structure, the retention of water on the wet tissue cover or in a gap between the upper cover main body and the lower cover main body can be reduced, so that the breeding of microorganisms is reduced; the sealing structure not only can prevent external microbial contamination, but also can firmly lock moisture carried by the wet tissue, so that the use safety is improved, and the service life is prolonged.

The utility model discloses a double -sided planer, related to planer technical field. The size specification of different wood exists difference, and the close of wood surface and planer roll is easy to lead to not close, and further causes planing precision deviation. The utility model discloses a work table and movable mechanism, and movable mechanism sets up at the bottom of work table, and movable mechanism includes setting up the motor of work table bottom no. The utility model discloses a work table, movable mechanism, support frame and motor no. are set up, and the work of motor no. is used, can drive rotating shaft rotation, make driving bevel gear rotate along with, can drive screw rod to rotate through the transmission of driven bevel gear along, thereby make screw seat move laterally outside screw rod, can adjust the distance between support frame, thereby conveniently limit the wood of different width, make the wood set up the just below of upper planer roll, thereby make wood surface and upper planer roll precisionly stick together, improve the processing accuracy of device.

This utility model discloses a high-platform ball valve with double sealing. It is characterized by comprising a valve body and a valve cover disposed at one end of the valve body. A first soft seal is provided at the contact surface between the valve body and the valve cover, and the first soft seal is disposed within a groove formed in the valve body. A first hard seal is also provided at the contact surface between the valve body and the valve cover, and the first hard seal is disposed inside the soft seal. This utility model achieves double sealing of the sealing parts in the ball valve, significantly improving reliability.
