Embodiment Construction
[0034] Such as Figure 1-7 As shown, the connection structure of the concrete slab structure of the present invention includes an I-shaped connecting tie rod 1 and two steel box sleeves 4; the shaft of the connecting tie rod 1 is provided with a direction mark 3. The ends of the steel boxes 4 are pre-embedded, and the positions of the two steel boxes 4 are corresponding; among them, the first steel box 4 is used as the active end of the connection, and the connecting rod 1 is pre-embedded in the box; the second steel box 4 is used as the connection At the passive end, only the empty box is pre-embedded; the two steel box casings 4 are provided with grouting holes 5 at the end away from the gap between the two concrete slabs.
[0035] Among them, the direction mark can adopt eye-catching marks such as color marks.
[0036] Preferably, the I-shaped connecting rod 1 includes a long side and short sides 2 located at both ends of the long side; and the two short sides 2 are perpen...

The invention relates to connection of concrete slab type structures, and particularly relates to a connecting structure and a connecting method of a concrete slab type structure. The connecting structure and the connecting method of the concrete slab type structure ensure that a connecting part is firm and sealed, and have the same compression resistance and tensile property as a slab body. The connecting structure comprises an I-shaped steel connecting pull rod and two steel box sleeves; a rod body of the connecting pull rod is provided with a direction mark; when concrete slabs are prefabricated, the steel box sleeves are pre-buried in the end parts of two adjacent concrete slabs, and the positions of the two steel box sleeves correspond to each other; the first steel box sleeve is used as a connecting driving end, and the connecting pull rod is pre-buried in a box; the second steel box sleeve is used as a connecting driven end, and only an empty box is pre-buried; and grouting holes are formed in the ends, far away from a gap between the two concrete slabs, of the two steel box sleeves.
Description
technical field [0001] The invention relates to the connection of concrete slab structures, in particular to a connection structure and a connection method of concrete slab structures. Background technique [0002] With the development of prefabricated building technology, the plane connection of concrete slab components can be realized by setting socket interfaces. For concrete slab structures with flat end faces, the traditional methods generally include post-cast laminated concrete on site, and post-cast concrete connections after the reinforcement is anchored. However, under the conditions of small gaps between concrete slabs and limited slab thickness, it is difficult to realize steel-anchored concrete construction. Contents of the invention [0003] The present invention aims at the defects existing in the prior art, and provides a connection structure and a connection method of a concrete slab structure. Through the mixed connection mode of mechanical connection an...
