Cushion block special for precast beam web and manufacturing method of cushion block
The invention relates to the field of precast beam web construction, in particular to a cushion block special for a precast beam web and a manufacturing method of the cushion block. An open clamping groove, binding wire round holes and sawteeth are formed/arranged in/on the cushion block. Mounting and fixation are convenient, the contact area between the cushion block and a formwork is reduced, exposed thin-layer slurry is prevented from falling off to generate marks, and the appearance of a beam body is improved. The manufacturing method of the cushion block special for the precast beam web comprises the steps of plant area arrangement and construction preparation, mold manufacturing, blending, material distribution, pressing, demolding, maintenance, stacking, packaging and putting for use. Self-production machining can be adopted, the size is accurate and uniform, concrete is compact, the strength is guaranteed, the thickness percent of pass of a steel bar protection layer is increased, the cost is saved, the transportation expense and the transportation loss for purchasing the cushion block are saved; and in addition, construction machinery and personnel allocation are complete,the construction speed is high, and the manufacturing method is suitable for precast box girders of various spans.
本发明涉及预制梁腹板施工领域，尤其涉及一种预制梁腹板专用垫块及其制作工法，垫块上设有开口卡槽、绑丝圆孔和锯齿，方便安装固定，且减少垫块与模板的接触面积，避免外露薄层浆体脱落产生印痕，提升梁体外观；预制梁腹板专用垫块的制作工法包括厂区设置及施工准备、制作模具、拌和、布料、压制、脱模、养护、堆放及包装和投放使用，可采用自生产加工，尺寸精确统一，混凝土密实、强度有保障，提高钢筋保护层厚度合格率，节约成本，节省了购买垫块的运费及运输损耗，且施工机械及人员配备，施工速度快，适用于各类跨径的预制箱梁。
