Abstract
The utility model provides a shear connector which comprises a vertical piece fixed on a steel structure member. The utility model is characterized in that the cross section of the vertical piece has a special shape; and a horizontal piece is arranged on the vertical piece and perpendicular to the vertical piece. With the technical scheme, the shear connector effectively increases the bending rigidity and the pressure-bearing surface of the shear connector, and improves the pull-out resistance of the shear connector by arranging the horizontal piece on the vertical piece, so as to improve the load-bearing capacity and greatly reduce the use amount of the shear connector. The utility model further improves the strength of the concrete slab and the steel beam, reduces the consumption of the building steel materials, provides great convenience for laying the steel reinforcements in the concrete slab, increases the construction efficiency, ensures the construction quality, and shortens the construction period. Therefore, the shear connector serves as an ideal shear connector.
Description
Technical field
The utility model relates to the shear connector between a kind of new combining structure member, can be directly used in steel and concrete combination beam or other combined members.
Background technology
Shearing connecting piece is the critical component of compound beam, promptly earlier these shearing connecting pieces is fixed on the girder steel, waters armored concrete slab afterwards more thereon.At present a large amount of extensively shearing connecting pieces of utilization are to take the lead peg, also can see the utilization of some bent-up bars as shearing connecting piece once in a while, and these shearing connecting pieces all have a common weakness, and promptly the bearing capacity of single shearing connecting piece is low.Connect for realizing shearing fully, need a lot of shearing connecting piece of quantity, situation was more outstanding when especially peg was taken the lead in use, sometimes also can the factor amount huge and all pegs all can't be arranged in the member, can only form part and shear and connect, its result will cause the compound action of compound beam to reduce, bearing capacity and rigidity reduce, in addition, because of the laying difficulty that too much also can increase reinforcing bar in the concrete slab of shearing connecting piece quantity, make troubles to construction.
The low main cause of shearing connecting piece bearing capacity commonly used at present is: bending rigidity is little and pressure-bearing surface is little, especially take the lead peg, its in loading process because flexural deformation, effectively pressure-bearing surface only is the very little part of its root, cause root the stress concentration phenomenon of height to occur, the concrete of its pressurized also will produce splitting crack and crushed.Therefore, improve the bearing capacity of shearing connecting piece, just must at first solve the low and little problem of bearing area of shearing connecting piece bending rigidity.
Summary of the invention
For overcoming that the bending rigidity that existing shearing connecting piece exists is low, pressure-bearing surface is little and the bearing capacity deficiency on stressed such as little, the utility model provides a kind of shearing connecting piece, this shearing connecting piece has bigger bending rigidity and bigger pressure-bearing surface, thereby can obtain very high-bearing capacity.
The utility model is finished by following technical proposal: a kind of shearing connecting piece, comprise the vertical part that is fixed on the steel member, and it is characterized in that cross section is special-shaped vertical part and is provided with perpendicular horizontal element.
The cross section of described vertical part is I-shaped, perhaps triangle, perhaps semicircle or half rectangle.
Described vertical part is upright shaped steel, i.e. the combination of one or more in i iron, angle steel, semi-steel pipe, the channel-section steel, and the opening of upright shaped steel is towards span centre.
Described vertical part is provided with through hole, is interspersed with horizontal element in the through hole, to strengthen the resistance to plucking ability of shearing connecting piece.
Described horizontal element is a round bar.
The utlity model has following advantage and effect: adopt such scheme, promptly adopt the vertical part of varying cross-section shape, be upright shaped steel, can effectively increase the bending rigidity and the pressure-bearing surface of shearing connecting piece, in loading process, make himself and around the concrete intensity of pressurized can both be not fully exerted, add that vertical part upper horizontal member can make shearing connecting piece have very high resistance to plucking ability, the high-bearing capacity of Chan Shenging can greatly reduce the usage quantity of shearing connecting piece again therefrom, only need just can realize shearing fully connection with a spot of shearing connecting piece, not only make the intensity of concrete slab and girder steel obtain advancing to improve, save a large amount of structural steels, the reinforcing steel bar laying that also can be in the concrete slab brings great convenience, and helps improving efficiency of construction, guarantees construction quality, accelerating construction progress is a comparatively ideal shearing connecting piece in fact.
