Abstract
A built-in shearing resistance steel plate reinforcement concrete combination beam relates to a steel-concrete combination beam. The present invention removes the difficulty that, when concrete strength of the steel-concrete combination beam is high, shearing resistance capacity of the beam is increased by increasing strength level of the concrete and cross area of the beam, thus increasing construction difficulty and investment, and the construction quality cannot be guaranteed. Cross section in the present invention is one or a plurality of steel plates (1) longitudinally arranged through length of the beam in the stress reinforced steel bar (2), stirrups (3) and concrete (4) in the rectangular beam. Shearing resistance force of the reinforcement concrete combination column in the built-in shearing resistance steel plate is equal to the sum of the shearing resistance force of the reinforced steel bar concrete bar and built-in steel plate. The shearing resistance force is 2 times of the reinforced steel bar concrete beam with the same cross area and material, the construction is convenient and the cost is saved.
Description
Technical field
The present invention relates to the steel-concrete composite beam of field of civil engineering.
Background technology
Diagonal compression failure takes place when avoiding reinforced concrete beam to be cut, and existing reinforced concrete beam often adopts following two kinds of measures in order to guarantee the shear-carrying capacity of beam: the one, and the enlarging section size, the 2nd, improve concrete design strength grade.The enlarging section size, influence the function of use of building or structure, when strength grade of concrete is higher, increase the shear-carrying capacity of beam again by the cross section of improving concrete strength grade and increase beam, not only increase difficulty of construction, also can obviously increase construction investment, and construction quality is difficult to also ensure.
Summary of the invention
The present invention is in order to solve existing steel one concrete combination beam when strength grade of concrete is higher, increase the shear-carrying capacity of beam again by the cross section of improving concrete strength grade and increase beam, influence the function of use of building or structure, increase difficulty of construction, also can obviously increase construction investment, and construction quality also is difficult to the problem that ensures, proposed a kind of reinforcement built-in anti-shear steel plate concrete combination beam, and the concrete technical scheme that addresses the above problem is as follows:
The present invention is made up of steel plate 1, longitudinal stress reinforcing bar 2, stirrup 3 and concrete 4, and cross section is that longitudinal stress reinforcing bar 2, stirrup 3 and the concrete 4 of rectangular beam is built-in with one to multiple block of vertical steel plate 1 through the beam length direction.
The shear-carrying capacity of the armored concrete compound beam of built-in anti-shear steel plate of the present invention equals the shear-carrying capacity and the built-in steel plate shear-carrying capacity sum of reinforced concrete beam, shear-carrying capacity is 2 times of reinforced concrete beam shear-carrying capacity of existing same cross-sectional, material, cost is saved in easy construction.Be applicable to the reinforced concrete beam that shearing is certain by sectional dimension, strength grade of concrete is certain that is born.

The specific embodiment two: describe present embodiment in conjunction with Fig. 1, the length of the steel plate 1 of present embodiment is identical with the length of steel frame; Thickness direction is parallel to deck-siding; Height is identical with the height of steel frame.
The shearing that steel plate 1 thickness is born according to the beam needs is determined.
The specific embodiment three: describe present embodiment in conjunction with Fig. 3, the difference of the present embodiment and the specific embodiment one is that cross section is that longitudinal stress reinforcing bar 2, stirrup 3 and the concrete 4 of rectangular beam periphery is built-in with two vertically through the steel plate 1 of the length direction of beam.
The specific embodiment four: in the concrete 4 of present embodiment is wrapped in steel frame and steel plate 1.
The preparation method of beam of the present invention:
At first, prop up beam bottom board; Then, form the steel frame of the beam of built-in anti-shear steel plate 1 by designing requirement; At last, side form and concreting are made reinforcement built-in anti-shear steel plate concrete combination beam.
Reinforcement built-in anti-shear steel plate concrete combination beam of the present invention is all identical with general reinforced concrete beam joint construction with the girder joint construction.
