Sealing backing plate, water stop rubber, sealing pressing plate, dormant bolt.The lower steel plate and oblique steel plate, which are at an angle of, is weldingly fixed on breastwork door
Lintel top；The sealing backing plate is weldingly fixed on oblique steel plate；The water stop rubber and sealing pressing plate pass through dormant bolt and string
Union nut is fixed on sealing backing plate and breastwork lintel.
Further, the sealing backing plate aperture, aperture Φ 17mm, aperture spacing are not more than 150mm.
Further, the water stop rubber uses p-type water stop rubber, aperture Φ 15mm.
Further, the sealing pressing plate presses the aperture of dormant bolt pattern, aperture Φ 17mm.
Further, the water stop rubber and sealing pressing plate position of opening are corresponding with sealing backing plate.
Further, the series connection nut is made of multiple nuts being cascaded.
Further, the length of the dormant bolt is slightly shorter than the outermost layer nut for nut of connecting.
The beneficial effects of the utility model are: a kind of built-in fitting of down-the-hole type gates of segmental shape lintel sealing is a kind of detachable
Structure has structure simple, and stability is good, and water-stagnating effect is good, for not having the deep water metal knot of emptying reservoir repair and maintenance
For structure, which has many advantages, such as to be easy to overhaul, it is convenient to replace.
Detailed description of the invention
Fig. 1 is the utility model structural profile illustration, is wherein schemed supplemented by lock gate leaf 9 and gate flap antipriming 10；
Fig. 2 is the front view of oblique steel plate；
Wherein: 1, lower steel plate；2, oblique steel plate；3, series connection nut；4, sealing backing plate；5, water stop rubber；6, sealing pressing plate；7,
Dormant bolt；8, breastwork second stage concrete；9, lock gate leaf；10, gate flap antipriming；11, breastwork.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.The present embodiment is with the utility model
Implemented premised on technical solution, the detailed implementation method and specific operation process are given, but the guarantor of the utility model
Shield range is not limited to the following embodiments.
As shown in Fig. 1~2, the utility model relates to a kind of down-the-hole type gates of segmental shape lintel sealing built-in fitting structure,
Including lower steel plate 1, oblique steel plate 2, series connection nut 3, sealing backing plate 4, water stop rubber 5, sealing pressing plate 6, dormant bolt 7.Under described
Steel plate 1 and oblique steel plate 2, which are at an angle of, is weldingly fixed on 11 lintel top of breastwork；The sealing backing plate 4 is weldingly fixed on oblique steel plate 2
On；The water stop rubber 5 and sealing pressing plate 6 pass through dormant bolt 7 and series connection nut 3 is fixed on sealing backing plate 4 and breastwork 11
On lintel.
The lower steel plate 1 and oblique steel plate 2 are arranged in breastwork lintel top by design requirement and weld by design requirement angle
Fixed, lower steel plate 1 and 2 material of oblique steel plate select Q345B.
The sealing backing plate 4 is fixed by welding on oblique steel plate 2, while in 4 aperture of oblique steel plate 2 and sealing backing plate, hole
Diameter Φ 17mm, aperture spacing are not more than 150mm, and 4 material of sealing backing plate is Q345B.
The water stop rubber 5 and 6 position of opening of sealing pressing plate are corresponding with sealing backing plate 4, logical with sealing backing plate 4, oblique steel plate 2
It crosses dormant bolt 7 and series connection nut 3 is fixed.
The water stop rubber 5 uses p-type water stop rubber, aperture Φ 15mm.
