Abstract
The utility model relates to a novel steel pipe concrete beam, including square steel pipe, twisted steel, concrete, its characterized in that: the lower part does not have the steel sheet of both sides in the roof beam, only sets up the bottom steel sheet, and lower part fretwork in the steel core concrete beam, reinforcing bar anchor in the concrete, reinforcing bar and lower part steel sheet welding, upper portion steel core concrete are connected with the bottom steel sheet through 4 reinforcing bars. Steel materials on the upper portion of the steel tube concrete beam and concrete are compressed together, double-layer steel plates on the middle lower portion of the beam are pulled, and threaded steel bars are symmetrically arranged in the horizontal two directions. The utility model has the advantages of reasonable design, the component part is prefabricated, and a small part needs the welding, adopts the welding to make reinforcing bar and steel sheet be connected, and it is comparatively convenient to be under construction, suits as prefabricated component at the job site assembly. The concrete material is saved, the dead weight of the structure is reduced, the construction cost is reduced, and the transportation is convenient to a certain degree.
Description
Technical Field
The utility model relates to a civil construction technical field especially relates to a novel steel tube concrete beam, is guaranteeing that conventional steel tube concrete improves intensity, rigidity, and shock resistance and refractiveness when saving advantages such as template, has further reduced the quantity of concrete, has alleviateed the structure dead weight.
Background
With the social progress and the development of technology, the concrete filled steel tube is more and more applied to the fields of bridges, plants and civil buildings. How to make the structure more economical, beautiful, light and durable while ensuring the existing advantages of the concrete-filled steel tube is a subject of thinking gradually.
Disclosure of Invention
In order to further improve prior art, reduce engineering cost, reduce the structure dead weight, the utility model provides a more economic steel pipe concrete roof beam. The utility model discloses a following technical scheme, a more economic, steel pipe concrete roof beam of light, including square steel pipe, twisted steel, concrete, its characterized in that: the lower part does not have the steel sheet of both sides in the roof beam, only sets up the bottom steel sheet, and lower part fretwork in the steel core concrete beam, reinforcing bar anchor in the concrete, reinforcing bar and lower part steel sheet welding, upper portion steel core concrete are connected with the bottom steel sheet through 4 reinforcing bars. Steel materials on the upper portion of the steel tube concrete beam and concrete are compressed together, double-layer steel plates on the middle lower portion of the beam are pulled, and threaded steel bars are symmetrically arranged in the horizontal two directions.
The beneficial technical effects obtained by adopting the technical scheme are as follows: the utility model has the advantages of reasonable design, the component part is prefabricated, and a small part needs the welding, adopts the welding to make reinforcing bar and steel sheet be connected, and it is comparatively convenient to be under construction, suits as prefabricated component at the job site assembly. The method of hollowing out the middle lower part of the steel pipe concrete beam not only keeps the advantages of the steel pipe concrete such as improving the strength, rigidity, shock resistance and fire resistance, but also saves the template; and concrete materials are further saved, the self weight of the structure is reduced, the construction cost is reduced, and the transportation is convenient to a certain degree.

Detailed Description
A novel steel pipe concrete beam comprises square steel pipes (1), concrete (2), steel bars (3) and steel plates (4). The method comprises the steps of cutting off two sides of the middle lower part of a square steel pipe (1), dismantling steel plates on two sides of the middle lower part of a beam, fixing a bottom steel plate (4) without moving, plugging three exposed surfaces with the steel plates (4), fixing a steel bar (3) on the bottom steel plate through welding or bolt connection, and inserting the upper end of the steel bar into upper concrete (2) for anchoring. And (3) pouring concrete into the steel pipe (1), wherein the middle lower part of the beam is not poured, and after the pouring, vibrating and curing are finished, the beam is formed into the steel pipe concrete beam with the hollow middle lower part and the whole body sealed.
The present invention is not limited to the above embodiments, and it should be noted that all the modifications and obvious variations made by those skilled in the art under the guidance of the present specification fall within the spirit and scope of the present specification, and should be protected by the present invention.
Claims (2)
1. A novel steel pipe concrete beam is characterized in that: the steel tube concrete beam is formed by connecting steel tubes, concrete and steel bars, the middle lower part of the steel tube concrete beam is hollowed, the steel bars are anchored in the concrete, the steel bars are welded with a lower steel plate, and the upper steel tube concrete beam is connected with a bottom steel plate through 4 steel bars.
2. A novel steel tube concrete beam according to claim 1, wherein: steel materials on the upper portion of the steel tube concrete beam and concrete are compressed together, double-layer steel plates on the middle lower portion of the beam are pulled, and threaded steel bars are symmetrically arranged in the horizontal two directions.
