Reinforcing method and reinforcing device for precast slabs
The invention discloses a reinforcing method and reinforcing device for precast slabs. The method comprises the steps that S1, the specification and number of reinforcing bars required to be added inholes of the precast slabs are obtained through structural calculation according to a load design value and concrete strength; S2, a precast slab floor is cleaned, and the position of each precast slab is determined; S3, according to a design drawing, atlas and field checking, the position of the hole of each precast slab is determined, and marking is carried out; S4, notches are formed in the positions, close to one ends of the precast slabs, above holes of the precast slab floor in the hole directions of the precast slabs, and the size of the notches preferably allows reinforcing bars to beplaced; S5, the reinforcing bars are placed in the holes, and the positions of the reinforcing bars are fixed through reinforcing bar supports; and S6, high-fluidity fine aggregate concrete is pouredinto the holes of the precast slabs. The invention further discloses a reinforcing device for the precast slabs corresponding to the reinforcing method. Through the adoption of the reinforcing methodand reinforcing device for the precast slabs, the load strength of an original precast slab floor in use can be improved, and the bearing capacity of the original whole precast slab floor is improved.
本发明公开一种预制板的加固方法及加固装置，包括S1，根据荷载设计值和混凝土强度，通过结构计算，得出所需在预制板孔洞中增加的配筋规格和数量；S2，清理预制板楼面，确定每块预制板的位置；S3，根据设计图、图集和现场核对，确定每块预制板的孔洞位置，并做好标记；S4，在预制板楼面的孔洞上方靠近预制板一端，沿预制板孔洞方向开设槽口，所述槽口大小以能放进配筋为宜；S5，将配筋置于孔洞中，所述配筋通过配筋支架进行位置固定；S6，向预制板孔洞中浇灌高流动性细石混凝土。进一步公开了与该加固方法对应的预制板加固装置，采用本发明可提升正在使用中的原预制板楼面荷载强度，提升原来整个预制板楼面承载力。
