Detailed Description
The concrete cantilever floor stressed steel bar and steel beam connecting structure of the utility model is described in detail below with reference to the attached drawings of the specification.
As shown in fig. 1 to 3, the utility model discloses a floor atress reinforcing bar and girder steel connection structure are hung to concrete, including girder steel main part 1, girder steel main part 1 is the I shape, and one side of girder steel main part 1 is equipped with a plurality of stiffening ribs 2, and the opposite side is equipped with a plurality of stiffening ribs two 3, and this connection structure still includes fixed connector, peg 5 and the reinforcing bar that is drawn 6, 1 roof one side of girder steel main part is equipped with a plurality of fixed connector, and fixed connector's specific quantity sets up a plurality ofly according to the difference of installation demand, can be with every fixed connector and girder steel roof welding, and girder steel main part roof middle part is equipped with a plurality of pegs 5, peg 5 is the same and the one-to-one with fixed connector quantity, the peg also weld with the girder steel roof, the roof of peg be equipped with the draw reinforcing bar complex draw-in groove, draw reinforcing bar one end and fixed connector lateral wall welding, the horizontal pole and the draw-in groove cooperation joint of peg roof, have improved the bearing capacity of the reinforcing bar that is drawn.
In order to facilitate the installation of the fixed connecting pieces and improve the accuracy of the distance between the fixed connecting pieces, a sliding groove 7 is formed in one side, where the fixed connecting pieces are installed, of the top wall of the steel beam top plate 8, the sliding groove 7 is a dovetail groove, the fixed connecting pieces are connecting plates 4, and dovetail blocks in sliding fit with the dovetail grooves are arranged at the lower ends of the connecting plates 4. One side that the girder steel roof was equipped with fixed connection spare is equipped with the scale sign 9 that can guarantee that the fixed connection spare interval is accurate. When the connecting plates 4 are installed, the connecting plates 4 are sequentially slid into the sliding grooves 7 of the steel beam top wall, each connecting plate is slid to the required scale through the scale marks 9 on the side edges of the steel beam top wall, the same interval between every two adjacent connecting plates is guaranteed, and the bearing stress of the longitudinal tension steel bars 6 is uniform. In addition, in order to guarantee the firmness of connecting plate and girder steel connection, can weld in connecting plate and girder steel roof junction after the connecting plate confirms the mounted position.
