Description
Technical field
The utility model relates to a kind of steel bell structures for connecing Prestressed concrete cylinder pipe.
Background technique
Prestressed concrete cylinder pipe (PCCP pipe) is to be twined using the strong concrete tube core with steel cylinder as liner
The water-supply-pipe that fine and close cement mortar protective course is formed is sprayed after ring orientation prestress steel wire, general every root canal is 5-6 meters long.But it is right
Landform adaptability is weaker, generallys use steel pipe in topography variation section and is laid with, to make Prestressed concrete cylinder pipe road and steel pipe
It is linked to be water delivery line, generally requires between steel pipe and cylinder concrete pipe and connected using bell and spigot.Wherein socket is and tube body one
Rise it is molding, the steel bellmouth of lengths of steel pipes generally uses steel plate welding fabrication.But since the steel plate of welding fabrication is than relatively thin, rigidity
Small, the effect deformation ratio Prestressed concrete cylinder pipe socket by native load is big, causes gap at bell and spigot to become larger, leak occurs
Situation.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide one kind and connect pre-stress steel cylinder
The steel bell structure of pipe of concrete.
It is for technical solution used by realization the purpose of this utility model:
A kind of steel bell structure connecing Prestressed concrete cylinder pipe, including internal layer steel construction and outer protective layer,
The internal layer steel construction includes cylindric steel cylinder and the transition ring flat-plate for being welded on described steel cylinder one end, the transition ring flat-plate with
Socket hoop is welded to connect, and the internal diameter of the transition ring flat-plate is consistent with the internal diameter of the steel cylinder and outer diameter is greater than the outer of the steel cylinder
Diameter, the internal diameter of the socket hoop is greater than the internal diameter of the transition ring flat-plate and outer diameter is less than the outer diameter of the transition ring flat-plate, the mistake
Cross the floor that reinforcement is welded at the position for being formed by L shape portion between ring flat-plate and the steel cylinder;The outer protective layer packet
It includes the steel fabric sheet being laid on outside the internal layer steel construction and is sprayed on outside the steel fabric sheet and coat the steel fabric sheet
The cement mortar of predetermined thickness inside.
The outer protective layer forms the first inclined plane part, transition part and the second inclined plane part in the position of corresponding steel bellmouth,
First inclined plane part and the second inclined plane part are connected by the transition part, the medial surface and the rib of first inclined plane part
One end of plate is connected, and the outboard end of second inclined plane part is connected with the end face of the socket hoop.
The floor be it is multiple, uniform intervals are arranged at the position in L shape portion.
The transition ring flat-plate, steel pipe and socket hoop are coaxially arranged mounting connection structure.
Compared with prior art, the utility model has the beneficial effects that
The rigidity of structure that the floor of steel bellmouth and reinforcement, reinforced concrete floor is collectively formed in the utility model increases
Greatly, deformation is almost the same with corresponding socket after by native load action, avoids deformation inconsistent the problem of causing leak.
Detailed description of the invention
Fig. 1 is the schematic diagram of the steel bell structure for connecing Prestressed concrete cylinder pipe of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
As shown in Figure 1, a kind of steel bell structure for connecing Prestressed concrete cylinder pipe of the utility model, including internal layer
Steel construction 1 and outer protective layer 2, the internal layer steel construction include cylindric steel cylinder and are welded on described steel cylinder one end
Transition ring flat-plate 5, the transition ring flat-plate and socket hoop 6 are welded to connect, the internal diameter of the transition ring flat-plate and the internal diameter one of the steel cylinder
It causes and outer diameter is greater than the outer diameter of the steel cylinder, the internal diameter of the socket hoop is greater than the internal diameter of the transition ring flat-plate and outer diameter is less than institute
The outer diameter of transition ring flat-plate is stated, is formed by between the transition ring flat-plate and the steel cylinder at the position in L shape portion and is welded with reinforcement use
Floor 7;The outer protective layer includes the steel fabric sheet 3 that winding is laid on outside the internal layer steel construction and is sprayed on described
The outer cement mortar 4 that the steel fabric sheet is coated on to interior predetermined thickness of steel fabric sheet.
Wherein, the transition ring flat-plate, steel pipe and socket hoop are coaxially arranged mounting connection structure.
Wherein, the outer protective layer forms the first inclined plane part 9 in the position of corresponding steel bellmouth, and transition part is with 11 and the
Two inclined plane parts 10, first inclined plane part and the second inclined plane part are connected by the transition part, first inclined plane part it is interior
Side is connected with one end of the floor, and the outboard end of second inclined plane part is connected with the end face of the socket hoop.
Wherein, the floor is multiple, and uniform intervals are arranged at the position in L shape portion, for example eight pieces, ontology three
Horn shape connect with the steel cylinder and connect with transition ring flat-plate for convenience, with the mating connection of outer protective layer, corresponding three
The corner at a angle end is cut off, and to increase welding contact area, or prevents from destroying outer protective layer.
The steel bell structure for connecing cylinder concrete pipe of the utility model, by welding excessive 5 He of ring flat-plate on steel cylinder
After socket hoop 6 forms steel bellmouth 8, first is that increasing floor 7 outside the excessive ring of steel bellmouth to adjust bellmouth steel loop stress, floor
7 is uniformly distributed using 8 pieces of steel plate;Reinforce second is that spraying fine and close cement mortar after being laid with steel fabric sheet 3 outside steel bellmouth 8 and floor 7
Layer forms protective layer, plays protective layer 2 and increases thickness, to achieve the purpose that increase rigidity.In this way, steel bellmouth and floor,
The rigidity of structure that reinforced concrete floor is collectively formed increases, and deforms and corresponding Prestressed concrete cylinder pipe after by native load action
Socket is almost the same, avoids deformation inconsistent the problem of causing leak.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
It also should be regarded as the protection scope of the utility model into retouching.
