企口叠合梁在装配式建筑中的应用与思考

The application and thinking of the tapered beam in prefabricated construction

随着我国“双碳”政策及智能建造和装配式建筑政策与技术大力推广,大量重载物流园仓储项目引入企口做法的装配式建造技术,基于搁置长度误差大及汽车吊上楼面作业,对预应力企口叠合梁梁端承载力等进行了研究。对搁置长度不足导致构件承载力下降提出了企口叠合梁相应的补强措施,补强效果明显,切实可行,为同类工程提供了一定的数据依据,具有一定工程实践意义。

With the promotion of prefabricated building policies and technologies,a large number of heavy-duty logistics park warehousing projects have introduced the prefabricated construction technology of groove and groove.The bearing capacity of prestressed tongued and grooved laminated beams is studied based on the large error of shelving length and the operation of truck lifting on the floor.In order to reduce the bearing capacity of the member due to the lack of shelving length,the corresponding strengthening measures of the tongue-and-groove laminated beam are put forward.The reinforcement effect is obvious and feasible,which provides certain data basis for similar projects and has certain engineering practice significance.
