Technical Field

[0001] The utility model belongs to the technical field of connectors and relates to a reinforced concrete slab bolt connection structure. Background Art

[0002] At present, the connection between reinforced concrete slabs in prefabricated low-rise buildings is generally carried out directly by bolt connectors. The tightness of the connection between the slabs of the house has a great impact on the safety of the house. Therefore, it is important to choose a bolt connector with good fastening reliability.

[0003] In the existing technology, two plates are mostly connected through a metal connecting box and then bolted connectors. Since the metal connecting box is made of bent and welded steel plates or cut from square steel tubes, if the steel plate of the metal connecting box is thin, the steel plate will deform greatly under the action of the bolt tightening force. If the steel plate is thicker, the cost will be higher. In addition, since the tightening force is not transmitted directly, it is easy to cause slippage and loosening. Therefore, the safety performance is poor and there is a lot of room for improvement. Summary of the Invention
