Abstract
The utility model relates to a steel mouthing socket steel pipe non-reinforcement prestressed concrete pipe, wherein, axial embedded longitudinal reinforcements are uniformly distributed in a concrete pipe core in same diameter; two ends of the longitudinal reinforcement are respectively fixed on a mouthing and a socket of the concrete pipe core; the mouthing and the socket of the concrete pipe core are respectively fixed with a steel pipe. The utility model has the advantages of very simple integral structure, scientific and reasonable design, good durability, impermeability and water seal capability of joint. The longitudinal reinforcement and the steel pipe are adopted to replace a reinforced skeleton frame. The utility model is of few using amount of steels, simple repair and maintenance and convenient construction operation, thereby greatly reducing the product cost and construction cost, and providing conditions for wide use of concrete pipes.
Description
Technical field
The utility model relates to concrete plug, especially a kind of steel faucet steel cylinder non-longitudinal rib prestressed concrete pipe.
Background technique
The steel faucet prestressed concrete pipe is a kind of pipeline that is mainly used in municipal administration, water conservancy, electric power, urban water supply system, also often is used in industrial waterline, field irrigation, plant pipe network.Present steel faucet prestressed concrete pipe cost is higher, causes the high main cause of steel faucet prestressed concrete plumber journey cost to be: 1. the rise of price of steel product causes that cost increases.The concrete pipe in-core is embedded with cylindrical reinforcement frame, and this Framework Of Steel Reinforcement is by a plurality of vertical muscle and circumferential reinforcement colligation or be welded, and the use amount of steel is bigger; 2. the Framework Of Steel Reinforcement fabricating cost is higher.When adopting artificial assembling reinforcement skeleton, manufacturing efficiency is lower, and the manufacture cycle is longer, and defect rate is higher; When adopting special device to install Framework Of Steel Reinforcement with welding manner, though the manufacture cycle shortens, defect rate reduces, and the machinery cost is higher.
In the actual production of steel faucet prestressed concrete pipe, the female end of inner tube wall and socket end are prone to microscopic crack, and the not high enough generation that also can cause microscopic crack of tube core longitudinal pulling force at present.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, reasonable in design, with low cost, less steel faucet steel cylinder non-longitudinal rib prestressed concrete pipe of use reinforcing bar is provided.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of steel faucet steel cylinder non-longitudinal rib prestressed concrete pipe; constitute by bellmouth, socket, concrete tube core, reinforcement wire, protective layer; bellmouth is coaxial and be packed in the two ends of concrete tube core respectively with socket; protective layer is coaxial on concrete pipe outer core cylinder; reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer; it is characterized in that: on the bellmouth of concrete tube core or socket, be fixed with a steel cylinder respectively, perhaps on bellmouth or socket, install a steel cylinder simultaneously.
And described steel cylinder is packed in the inner edge position of the bellmouth and the socket of concrete tube core.
And described steel cylinder adopts welding manner to be packed on the bellmouth and socket of concrete tube core.
And described protective layer is a slush.
Advantage of the present utility model and beneficial effect are:
1. only dispose steel cylinder and replace Framework Of Steel Reinforcement at the concrete pipe in-core, its concrete pipe outer core keeps original reinforcement wire, whole tube core still is a reinforced concrete construction, makes tubing still have very strong resistance to pressure like this, but the steel material that uses reduces greatly.
2. adopt flexible faucet structure, have good joint Watertightness, and constructing operation is easy, tube material and tube wall is thin, and the body own wt is lighter, and the opposing uneven settlement is very capable.
3. this concrete pipe has saved the welding process of cylindrical reinforcement frame on process treating, greatly reduces the fabricating cost of tubing, has saved the molding time of whole tubing, has improved the manufacturing efficiency of tubing.
4. the steel cylinder that installs of bellmouth or socket end can improve the impermeability of bellmouth or socket end.
5. the utility model overall structure is very simple, design science is reasonable, have favorable durability, impermeability and joint water closure, adopt steel cylinder to replace Framework Of Steel Reinforcement, the steel use amount is less, maintenance maintenance is simple and constructing operation is easy, greatly reduces the cost and the construction cost of product, is the widely-used condition of having created of concrete pipe.
Description of drawings
Fig. 1 is the utility model structural representation (broken section);
Fig. 2 is that the A-A of Fig. 1 is to cross-sectional view;
Fig. 3 is that the B-B of Fig. 1 is to cross-sectional view.
Embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
This steel faucet steel cylinder non-longitudinal rib prestressed concrete pipe; constitute by bellmouth 1, socket 6, concrete tube core 2, reinforcement wire 4, protective layer 5; bellmouth is coaxial and be packed in the two ends of concrete tube core respectively with socket; protective layer is a slush and coaxial on concrete pipe outer core cylinder; reinforcement wire is wrapped on the interior concrete pipe outer core cylinder of protective layer; on the bellmouth of concrete tube core or socket, be fixed with a steel cylinder 3 respectively, perhaps on bellmouth or socket, install a steel cylinder (shown in the present embodiment accompanying drawing) simultaneously.
This steel cylinder is packed in the inner edge position of the bellmouth and the socket of concrete tube core.
This steel cylinder adopts welding manner to be packed on the bellmouth and socket of concrete tube core.
Joint socket of the present utility model is a flexible interface, therefore has good Watertightness, even also can effectively ensure the seal of whole pipeline under the situation of foundation settlement, and prevents that effectively fed sheet of a media from leaking.Because the utility model also is a reinforced concrete construction,, reduced the difficulty and the construction cost of construction, and maintenance maintenance is simply easy so can resist sizable external pressure load.
