Background
The double-steel-plate-concrete combined wallboard structure is an important structural form in a steel-concrete combined structure, and is a structural form formed by connecting steel plates on two sides and concrete in the middle through a shear connector, so that the combined structure can exert good overall performance and strengthen the out-of-plane shear resistance. Through the mutual constraint action of the steel plates on the two sides and the built-in concrete, the whole structural body has the advantages of high bearing capacity, good ductility, excellent earthquake resistance, impact resistance, leakage resistance and the like. The method is widely applied to nuclear containment, blast wall, polar offshore structure, ship structure and other directions.
The shear connector who uses now has to wear the bolt and leads to the condition of both sides steel sheet unevenness, under the non-to-wear condition, the shear connector has the relatively poor condition of ability of shearing or tensile strength, and traditional connecting piece is because little with the steel sheet welding interface simultaneously, appears the interface easily and slides. The above disadvantages of the conventional connector may cause the shear connector and the steel plate to not work normally in cooperation, and may cause structural failure to cause great hidden trouble.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve present single connecting piece and steel sheet welding interface little, the welding seam reliability is low, the connecting piece that probably appears in the structure and the condition that the steel sheet breaks away from to and connecting piece tensile and shear capacity are poor, reduce structural integrity's problem, provide a two steel sheet-concrete composite wallboard connecting pieces.
The utility model provides a two steel sheet-concrete combination wallboard connecting pieces, including two steel sheets and a plurality of structural connection spare, install a plurality of structural connection spare between two steel sheets, structural connection spare includes two angle steel connecting pieces, and two angle steel connecting pieces set up relatively, and the outside both ends of two angle steel connecting pieces respectively with two steel sheet fixed connection.
Preferably, the angle steel connecting piece is formed by welding an equal-edge angle steel and a rectangular steel plate with the side length being the single-edge length of the equal-edge angle steel.
Preferably, the rectangular steel plate is provided with bolt holes and welded with cylindrical bolts.
Preferably, the round holes of the two opposite angle steel connecting pieces and the bolts penetrate through each other to form left and right limiting.
Preferably, the distance between the adjacent structural connecting pieces is at least slightly larger than the width of the equal-edge angle steel, so that the upper angle steel connecting piece and the lower angle steel connecting piece can be translated and connected in a penetrating manner during construction conveniently
Preferably, the angle steel connecting piece is fixed with the adjacent steel plate through fillet weld double-sided full welding.
Two steel sheet-concrete composite wall panel connecting pieces's beneficial effect do:
1. the utility model relates to a succinct, convenient for material collection can carry out batch processing, labour saving and time saving at the steel processing factory.
2. The utility model discloses easily processing, the construction is convenient, and two angle steel connecting pieces wear relatively from top to bottom and form wholly, keep under the smooth condition in the steel sheet both sides, guaranteed the tensile and the shear resistance performance of connecting piece simultaneously, strengthened the wholeness ability of structure greatly.
