[0003] The present invention aims at the disadvantages that the concrete in the composite structure must have shrinkage and creep in the prior art, but the connection key cannot be strained during the shrinkage and creep process of the concrete, resulting in stress redistribution or concrete cracks, etc. Elastic aprons are set at the connection part of the connection key, which can make the connection key and the concrete change synergistically, reduce the redistribution of concrete shrinkage stress, and the elastic apron increases the expansion and contraction performance of the connection key, so as to adapt to the shrinkage and creep of the concrete in the composite structure, and avoid Concrete shrinkage cracks, elastic rubber ring composite structure connection key to improve the fatigue resistance of the composite structure

Embodiment 1
[0020] Elastic rubber ring combination structure connection key, such as Figure 1 to Figure 3 As shown, it includes corrugated steel web 1, connecting accessory 2, concrete 3, connecting main part 4, concrete 3 is connected with connecting main part 4, connecting main part 4 is welded with connecting accessory 2, connecting accessory 2 and corrugated steel web 1 Welding, the elastic rubber ring 5 is wrapped on the connecting main part 4 .
[0021] The connecting main part 4 is a peg 41 , and the elastic rubber ring 5 is wrapped around the welding part between the peg 41 and the connecting accessory 2 . By setting the elastic rubber ring at the welding part of the stud 41 and the connecting accessory 2, the joint key and the concrete can be changed synergistically, reducing the redistribution of the shrinkage stress of the concrete. shrinkage and creep, avoid concrete shrinkage cracks, and improve the fatigue resistance of the composite structure. The connecting main part 4 ...

The invention relates to a transition connecting device between connectors, and discloses an elastic rubber ring combined structure connector. The elastic rubber ring combined structure connector comprises a corrugated steel web (1), a connecting accessory (2), a concrete (3) and a connecting main part (4), the concrete (3) is connected with the connecting main part (4), the connecting main part (2) is welded to the connecting accessory (2), the connecting accessory (2) is welded to the corrugated steel web (1), and the connecting main part (4) is wrapped with elastic rubber rings (5). The arrangement of the elastic rubber rings at the connecting position of the connector realizes the cooperative change of the connector and the concrete and reduces the shrinkage stress heavy distribution of the concrete, and the elastic rubber rings increase the telescoping performance of the connector to be adapted to the shrinkage and creep of the concrete in the combined structure in order to avoid the shrinkage cracks of the concrete and improve the fatigue resistance of the combined structure.
Description
technical field [0001] The invention relates to a transition connection device between connecting keys, in particular to a connecting key with an elastic rubber ring combined structure. Background technique [0002] At present, under the condition of constant temperature, the concrete in the combined structure has shrinkage and creep. The connection keys such as studs are welded to the steel plate. It will not expand and contract, causing the stress redistribution of the combined structure, resulting in cracks and other undesirable phenomena in the concrete, which will affect the structural strength and service life of the combined structure. Contents of the invention [0003] The present invention aims at the disadvantages that the concrete in the composite structure must have shrinkage and creep in the prior art, but the connection key cannot be strained during the shrinkage and creep process of the concrete, resulting in stress redistribution or concrete cracks, etc. E...
