Connecting structure and construction method of non-rib concrete closely-spliced laminated slab and frame beam

WANG NENGYAN / PENG YAPING

The invention provides a connecting structure of a non-rib concrete closely-spliced laminated slab and a frame beam, which comprises an additional steel bar extending into a support, a fiber sheet, a steel plate and a steel nail, and the strength and/or diameter of the additional steel bar extending into the support are/is variable; the fiber sheet is adhered to the bottom surface of the laminated slab along the bottom edge of the frame beam; and the steel plate is pressed on the bent surface of the fiber sheet and is anchored by the steel nails. The invention further provides a construction method of the connecting structure of the non-rib concrete closely-spliced laminated slab and the frame beam. The overall stress performance of the beam-slab joint can be effectively improved, it is effectively guaranteed that the fiber sheets play a role, and the overall stress performance of the beam-slab structure is improved.

本发明提供了一种不出筋混凝土密拼叠合板与框架梁的连接结构，包括：伸入支座附加钢筋、纤维片材、钢板以及钢钉，所述伸入支座附加钢筋的强度和/或直径可变；所述纤维片材沿框架梁底边粘贴到叠合板底面；所述钢板压在所述纤维片材弯折表面处并且用所述钢钉进行锚固。本发明还提供一种不出筋混凝土密拼叠合板与框架梁的连接结构的施工方法。本发明可有效提高梁板节点的总体受力性能，有效保证纤维片材发挥作用，提高梁板结构的整体受力性能。
