Abstract
The utility model relates to the field of prestress civil engineering, in particular to a concrete prestress steel pipe beam. The concrete prestress steel pipe beam comprises a semi-arc concrete beam body; a reinforcing cage skeleton is arranged inside the concrete beam body; through holes are formed in the middle of the concrete beam body; prestress steel pipes are arranged inside the through holes. The concrete prestress steel pipe beam has the advantages and positive effects that as the prestress steel pipes are additionally arranged into the beam body, the stress area of prestress inside the bean body is increased, and the bearing capacity of the beam body is improved; the beam has low possibility of being worn, and the manufacturing of the beam is simpler and more convenient in comparison with a manufacture method that prestress steel bars are added.
Description
Technical field
The utility model relates to prestressing force field of civil engineering, especially a kind of concrete prestress steel pipe beam.
Background technology
Fish belly sill, because its rigidity of section is large, holistic resistant behavior is good, save the advantages such as material, is widely used in engineering construction.
But existing fish belly sill inside adopts prestressed reinforcement more, and structure is comparatively single, and reinforcing bar easily weares and teares, and affects the prestressing force of beam body, causes potential safety hazard.
Summary of the invention
Problem to be solved in the utility model is to overcome prior art deficiency, and a kind of concrete prestress steel pipe beam is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of concrete prestress steel pipe beam, comprise concrete beam body, described concrete beam body is half arc, described concrete beam body inside arranges reinforcement cage skeleton, described concrete beam body middle part arranges through hole, and described through hole inside arranges pre-stressed steel pipe.
Wherein, described through hole is multiple.
Advantage and the good effect that the utlity model has are: add pre-stressed steel pipe at Liang Tizhong, increase the inner prestressed lifting surface area of beam body, improve the stress performance of beam body, and not easy to wear, and also more easy than adding prestressed reinforcement to make.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
In figure: 1, concrete beam body, 2, reinforcement cage skeleton, 3, through hole,
4, pre-stressed steel pipe.
The specific embodiment
As shown in Figure 1, a kind of concrete prestress steel pipe beam, comprises concrete beam body 1, and concrete beam body 1 is half arc, and concrete beam body 1 inside arranges reinforcement cage skeleton 2, and described concrete beam body 1 middle part arranges through hole 3, and through hole 3 inside arrange pre-stressed steel pipe 4.Through hole 3 is multiple, each through hole 3 prestressed steel pipe 4 respectively.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
Claims (2)
1. a concrete prestress steel pipe beam, comprise concrete beam body, it is characterized in that: described concrete beam body is half arc, described concrete beam body inside arranges reinforcement cage skeleton, described concrete beam body middle part arranges through hole, and described through hole inside arranges pre-stressed steel pipe.
2. a kind of concrete prestress steel pipe beam according to claim 1, described through hole is multiple.
