Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a connection structure of prefabricated plate 1 and prefabricated column 2, including prefabricated plate 1 and prefabricated column 2. The precast slab 1 is provided with a pouring hole 11, and the pouring hole 11 is a through hole. The precast column 2 abuts against the precast slab 1 and blocks one opening of the casting hole 11.
As shown in fig. 2 and 4, the wall of the pouring hole 11 gradually shrinks towards the end away from the precast column 2, and forms a first inclined wall 111; the wall of the pouring hole 11 gradually shrinks towards one end close to the prefabricated column 2, and a second inclined wall surface 113 is formed; a straight wall surface 112 is formed between the first inclined wall surface 111 and the second inclined wall surface 113. A first reinforcement bar 12 extends into the hole in the flat wall 112.
In the axial direction of the casting hole 11, the length of the first inclined wall surface 111 is one third of the hole length of the casting hole 11, and the length of the second inclined wall surface 113 is one third of the hole length of the casting hole 11.
