Abstract
The utility model discloses a concrete steel pipe column lining reinforced connecting pipe. The middle section of the pipe is a cylindrical section, the outer diameter of the cylindrical section is the same with the inner diameter of a steel pipe forming a steel pipe column, the two ends of the cylindrical section are gradually contractive cone-shaped connecting sections, an annular reinforcement flat plate is arranged inside the cylindrical section, multiple uniformly distributed reinforcement vertical plates are respectively arranged on the upper surface and the lower surface of the annular reinforcement flat plate, and each reinforcement vertical plate is respectively moulded on the inner wall of the pipe along the radial direction of the inner circle of the pipe in an integrated manner. According to the concrete steel pipe column lining reinforced connecting pipe, the annular reinforcement flat plate and multiple uniformly distributed vertical plate reinforcement structures are arranged in the pipe, so that strength of a joint of the concrete steel pipe column is enhanced; the gradually contractive cone-shaped structures are adopted at the two ends, the cone-shaped connecting sections are inserted into the steel pipe when the concrete steel pipe column lining reinforced connecting pipe is used, and the joint of the concrete steel pipe column is reinforced. Therefore, a concrete steel pipe column formed by connecting the concrete steel pipe column lining reinforced connecting pipe is firm and reliable, and the concrete steel pipe column lining reinforced connecting pipe is easy to use.
Description
Technical field
The utility model relates to a kind of connecting tube of steel pipe column, particularly a kind of concrete steel tubing string liner connecting tube of putting more energy into.
Background technology
Encased structures abroad existing decades history, China from 60, applications that also the begin one's study seventies, existing application in the large scale industry factory building.Encased structures i.e. fill concrete in steel pipe, and two kinds of materials with different properties are combined into holistic composite construction.The characteristic of steel is intensity height, has elastoplasticity, but easy unstability; Concrete has anti-compression property preferably, but fracture resistance is poor.The two combination can make concrete be in the lateral confinement pressured state, and its compressive strength can significantly improve, and owing to the existence of core concrete, has improved the rigidity of steel pipe, thereby has improved structure bearing capacity greatly simultaneously.In a plurality of project engineering constructions, all use concrete filled steel tube.
Along with the fast development of builing industry, encased structures is more and more higher, and therefore, that how to realize steel pipe preferably firmly is connected to become the problem that unit in charge of construction need solve.
The utility model content
The utility model provides a kind of concrete steel tubing string liner connecting tube of putting more energy into for solving the technical problem that exists in the known technology, and the concrete steel tubing string that adopts this pipe fitting to be connected to form is solid and reliable.
The utility model for the technical scheme that solves the technical problem that exists in the known technology and take is: a kind of concrete steel tubing string liner connecting tube of putting more energy into, the interlude of this pipe fitting is cylindrical section, the external diameter of described cylindrical section is identical with the internal diameter of the steel pipe that forms steel pipe column, the two ends of described cylindrical section are the taper connection sections of shrinking gradually, being provided with annular in the inside of described cylindrical section strengthens dull and stereotyped, described annular strengthen dull and stereotyped above and below a plurality of uniform reinforcement risers are all arranged, each described reinforcement riser is all radially one-body molded on the inwall of this pipe fitting along the interior circle of this pipe fitting.
Advantage and the good effect that the utlity model has are: strengthen the structure of dull and stereotyped and uniform a plurality of reinforcement risers by annular is set in pipe fitting, strengthened the intensity of concrete steel tubing string junction; Employing forms the structure of tapered conical at both ends, during use, the taper connection section extend in the steel pipe, concrete steel tubing string junction is played the effect of reinforcement.Therefore, the concrete steel tubing string that adopts this pipe fitting to be connected to form is solid and reliable.And the utility model is easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is face upwarding stereogram of the present utility model.
Among the figure: 1, taper connection section; 2, strengthen riser; 3, cylindrical section; 4, steel pipe; 5, annular is strengthened dull and stereotyped; 6, weld seam.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, a kind of concrete steel tubing string liner connecting tube of putting more energy into, the interlude of this pipe fitting is cylindrical section 3, the external diameter of described cylindrical section 3 is identical with the internal diameter of the steel pipe 4 that forms steel pipe column, the two ends of described cylindrical section 3 are the taper connection sections 1 of shrinking gradually, be provided with annular in the inside of described cylindrical section 3 and strengthen dull and stereotyped 5, on described annular strengthens dull and stereotyped 5 and below a plurality of uniform reinforcement risers 2 are all arranged, each described reinforcement riser 2 is all radially one-body molded on the inwall of this pipe fitting along the interior circle of this pipe fitting.
During use, adopt weld seam 6 that this pipe fitting and the two joint steel pipes 4 that lay respectively at its two ends are linked together, solid and reliable.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
