A kind of prestress steel bobbin of tool guide structure
Technical field
The utility model relates to a kind of steel cylinder pipe, relates in particular to a kind of prestress steel bobbin of tool guide structure.
Background technique
Widely used steel faucet prestressed concrete pipe in large-scale liquid conveying engineering, owing to be inlaid with a steel cylinder at this concrete pipe in-core, and these steel cylinder two ends are coaxial respectively directly to be packed on steel bellmouth and the steel socket, thereby make whole concrete pipe self form an airtight integral body, therefore efficiently solve because of carrying fluid pressure to cause the problem of carrying liquid to exosmose by concrete tube wall.
But in use there are the following problems for steel faucet prestressed concrete pipe of the prior art, promptly because the uncontrollability of installation process, when bellmouth docks with socket, in case depart from, the concrete of bellmouth and spigot comes off easily, thereby influences construction speed.
The model utility content
The utility model provides a kind of prestress steel bobbin of tool guide structure at the drawback of prior art.
The prestress steel bobbin of tool guide structure described in the utility model; comprise that two ends are coaxially arranged with the steel cylinder pipe of steel pipe socket and steel pipe bellmouth respectively; described steel cylinder inner tube wall and steel pipe socket inwall are provided with the Steel Fiber Reinforced Concrete layer; described steel cylinder pipe outer wall and steel pipe bellmouth outer wall are provided with cement mortar protective course; described steel pipe bellmouth inwall is taper; the outer wall of described steel pipe socket is taper, and the taper of the taper of described steel pipe bellmouth inwall and steel pipe socket outer wall is complementary.
In the prestress steel bobbin of tool guide structure described in the utility model, described steel pipe socket outer wall is arranged with seal ring.
In the prestress steel bobbin of tool guide structure described in the utility model, be wound with reinforcement wire on steel cylinder pipe outer wall in the described cement mortar protective course and the steel pipe bellmouth outer wall.
In the prestress steel bobbin of tool guide structure described in the utility model, the taper of steel pipe bellmouth inwall is set to be complementary with the taper of steel pipe socket outer wall, make when two prestress steel bobbins make up mutually, the socket of a steel cylinder pipe is followed the smooth and easy insertion of conical inboard wall of the bellmouth of another steel cylinder pipe, the concrete that has caused when having avoided socket and bellmouth deviation comes off, and has accelerated construction speed greatly.
Description of drawings
Fig. 1 is the structural representation of the prestress steel bobbin of tool guide structure described in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1; the prestress steel bobbin of tool guide structure described in the utility model; comprise that two ends are coaxially arranged with the steel cylinder pipe 4 of steel pipe socket 6 and steel pipe bellmouth 3 respectively; described steel cylinder pipe 4 inwalls and steel pipe socket 6 inwalls are provided with Steel Fiber Reinforced Concrete layer 5; described steel cylinder pipe 4 outer walls and steel pipe bellmouth 3 outer walls are provided with cement mortar protective course 1; described steel pipe bellmouth 3 inwalls are taper; the outer wall of described steel pipe socket 6 is taper, and the taper of the taper of described steel pipe bellmouth 3 inwalls and steel pipe socket 6 outer walls is complementary.
Pass through said structure, when two prestress steel bobbins are made up mutually, the socket of a steel cylinder pipe is followed the smooth and easy insertion of conical inboard wall of the bellmouth of another steel cylinder pipe, and the concrete that has caused when having avoided socket and bellmouth deviation comes off, and has accelerated construction speed greatly.
Sealing effect when pegging graft for strengthening two steel cylinder pipes, as shown in Figure 1, also can be at the sheathed seal ring 7 of steel pipe socket 6 outer walls.
In the prestress steel bobbin of tool guide structure described in the utility model, be wound with reinforcement wire 2 on steel cylinder pipe 4 outer walls in described cement mortar protective course 1 and steel pipe bellmouth 3 outer walls, to improve the adhesive quality and the soundness of cement mortar protective course 1.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in specification and the mode of execution, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
