Safety weathertight door

Abstract

A safety weathertight door is characterized in that concave steel pillars are vertically disposed within two sides of a steel structured door body; a plurality of rebars are evenly disposed in each concave steel pillar from top to bottom; guide branch rails are mounted on the concave steel pillars outside the rebars; guide pulleys of bird-shaped castings are disposed on the guide branch rails; the bird-shaped castings are mounted on two sides of a bottom beam and are rotatably connected with the same; a motor is mounted at the top of the steel structured door; the motor is connected with beak ends of the bird-shaped castings on the bottom beam, through first wire ropes turned by fixed pulleys provided on two sides of the top of the steel structured door; one end of rain cloth is fixedly connected with the top of the steel structured door, and the other end of the rain cloth is fixedly connected with the upper portion of the bottom beam; a plurality of small steel rods evenly penetrate the rain cloth from bottom to top, to the top of the steel structured door body. The safety weathertight door meets the need of a large-scale steel structured factory for omission of a protective door and is light in weight, easy to maintain and high in safety.

Description

technical field [0001] The invention relates to a door body for a large-scale steel structure factory building, in particular to a safe weatherproof door with the effect of blocking wind and rain. Background technique [0002] With the rapid development of society, steel structure factory buildings emerge in endlessly, and the corresponding steel structure factory doors are also various. These factory doors are only suitable for small and medium-sized steel structure factory buildings. For giant steel structure factory buildings, the space occupied by left and right sliding doors and ordinary double doors is too large, the weight is too heavy, and more materials are consumed, which is neither economical nor economical. Reasonable, but the upper and lower telescopic rolling shutters are easy to be damaged and difficult to maintain because of their large size; so far, large-scale steel structure workshops generally do not have protective doors, but whenever the weather is wind...

[0002] With the rapid development of society, steel structure factory buildings emerge in endlessly, and the corresponding steel structure factory doors are also various. These factory doors are only suitable for small and medium-sized steel structure factory buildings. For giant steel structure factory buildings, the space occupied by left and right sliding doors and ordinary double doors is too large, the weight is too heavy, and more materials are consumed, which is neither economical nor economical. Reasonable, but the upper and lower retractable shutter doors are easy to be damaged and difficult to maintain because of their large size; so far, large steel structure workshops generally do not have protective doors, but whenever the weather is windy and rainy, a large part of the edge of the workshop cannot be constructed.
