Construction method for reinforcing post-cast slab strip of prefabricated laminated slab
The invention discloses a construction method for reinforcing a post-cast slab strip of a prefabricated laminated slab, which is characterized in that threaded steel sleeves are reserved at the bottom of the slab when the laminated slab is produced, and the threaded steel sleeves are symmetrically arranged across the post-cast slab strip; secondly, a formwork is erected, a sponge strip is pasted on the formwork in advance, after the prefabricated laminated slab is installed, a harness cord screw is screwed into a threaded steel sleeve embedded in the laminated slab from the lower portion, double steel pipes with the same diameter are placed below the formwork, the double steel pipes are fixed below the formwork through mountain-shaped clamps and nuts, then the nuts below the harness cord screw are continuously screwed, and the double steel pipes are fixed to the lower portion of the formwork; and the prefabricated laminated slab is tightly adhered to the template. The deformed steel bar sleeve is pre-arranged in the laminated slab, and the prefabricated laminated slab is tightly attached to the formwork by oppositely pulling the harness cord screw and the deformed steel bar sleeve in the prefabricated laminated slab. The quality problem caused by grout leakage during concrete pouring is avoided, one-time optimization of concrete pouring is achieved, the reinforcing device can be repeatedly used, and cost cannot be increased too much.
本发明公开了一种预制叠合板后浇板带加固的施工方法，在叠合板生产时在板底预留螺纹钢套筒，所述螺纹钢套筒隔着后浇板带对称设置；然后搭设模板，模板上提前粘贴海绵条，待预制叠合板安装完成后，从下方将通丝螺杆拧入叠合板中预埋的螺纹钢套筒里，并在模板下方放置同直径的双钢管，通过山型卡+螺母将双钢管固定在模板下方，随后不断拧紧通丝螺杆下方的螺母，直至预制叠合板与模板粘贴紧密。本发明通过在叠合板中预设螺纹钢套筒，通过通丝螺杆与预制叠合板中螺纹钢套筒对拉，使预制叠合板紧贴模板。避免了因混凝土浇筑漏浆而产生的质量问题，实现混凝土浇筑一次成优，而且加固装置可以多次重复使用，不会增加较多成本。
