Embodiment Construction

[0027] The present embodiment will be described in detail below in conjunction with the accompanying drawings.

[0028] A steel plate 6 is arranged at the bottom of the concrete roof beam 8, and the thickness of the steel plate 6 is 14mm. A concrete roof beam 1 is arranged above the middle part of the concrete roof beam 8. The concrete roof beam 1 is 2.5m above the elevation of the top of the concrete roof beam 8, and the height of the concrete roof beam 1 is 600mm, width 250mm, set concrete slanted beam 2 between concrete top beam 1 and concrete side beam 7, the vertical section height of concrete slanted beam 2 is 200mm, set four steel suspension cable 3 tie points on top of concrete roof beam 8 , the positions of the 3 pull nodes of the steel suspension cables are respectively set at 1 / 6 span of the concrete roof beam, 1 / 3 span of the concrete roof beam, 2 / 3 span of the concrete roof beam, and 5 / 6 span of the concrete roof beam. Four steel suspension cables 3 are set betwee...

Abstract

The invention discloses a reinforced construction method of a concrete roof beam. The method is characterized in that a steel plate is arranged at the bottom of the concrete roof beam, a concrete topbeam is arranged above the middle of the concrete roof beam, a concrete oblique beam is arranged between the concrete top beam and a concrete side beam, four steel suspension cable nodal points are arranged on the top of the concrete roof beam, four steel suspension cables are arranged between the concrete top beam and the concrete roof beam, a steel pull rod is arranged at the center position ofthe cross section of the concrete top beam, and the steel pull rod is fixed to the lower surface of the steel plate after prestressed tension. The method has good safety performance and high bearing capacity.

Description

technical field [0001] The invention relates to a reinforcement construction method for concrete roof beams, which is suitable for the construction field. Background technique [0002] Concrete roof beams need to be reinforced when the bearing capacity is insufficient. Usually, the concrete roof beam section is enlarged or reinforced with steel plates. When the concrete roof beam section is enlarged, the net height of the top floor will be reduced, which will affect the use function, and It is often difficult for the reinforced concrete to form a whole with the original concrete; and when the steel plate is used for reinforcement, the steel plate’s stiffness is often much greater than that of the concrete, and the bearing capacity will be small under the same deformation. limited. Concrete roof beams can be reinforced by taking advantage of their particularity because they are located at the height of the building. Contents of the invention [0003] The invention provide...
