Construction method for local transformation structure of unbonded prestressed plate
The invention discloses a construction method of an unbonded prestressed plate local transformation structure. The unbonded prestressed plate local transformation structure comprises original column bodies, original beam bodies connected between the adjacent original column bodies, original floor slabs connected to the original beam bodies, original inter-beam prestressed tendons connected between the original beam bodies, original lap joint prestressed tendons and original floor slab prestressed tendons which are arranged between the original floor slabs, and to-be-transformed floor slabs arranged on the original floor slabs, wherein the original lap joint prestressed tendons and the original floor slab prestressed tendons are arranged between the original floor slabs; according to the method, through the arrangement of the inspection holes and the chiseled prestressed tendon belts, the original prestressed tendons can be found conveniently, and the tendon arrangement condition of the transformed floor slab is defined; through the arrangement of the cutting first hole, the cutting second hole and the cutting third hole, on one hand, the prestressed tendons can be anchored, and on the other hand, the prestressed tendons can be cut and observed; due to the arrangement of the new prestressed tendons, the stress of a reformed structure formed later can be guaranteed; and the carbon fiber cloth and the reinforcing area are bonded in a combined manner, so that the strength of the improved structure is improved.
本发明公开了一种无粘结预应力板局部改造结构的施工方法，无粘结预应力板局部改造结构包含原柱体、连接于相邻原柱体之间的原梁体、连接于原梁体上的原楼板、连接于原梁体之间的原梁间预应力筋、设置于原楼板间的原搭接预应力筋和原楼板预应力筋以及设置于原楼板上的待改造楼板；本发明通过探孔和凿除预应力筋带的设置，利于对原有预应力筋的查找，明确改造楼板的布筋状况；通过切割第一洞、切割第二洞和切割第三洞的设置，一方面利于对预应力筋进行锚固，另一方面利于预应力筋的切割和观察；新预应力筋的设置，利于保证后形成的改造结构的受力；且联合粘贴碳纤维布和加固区，利于提高改造结构的强度。
