The utility model discloses a slurry stop structure of the bottom membrane of concrete prefabricated members, which comprises a floor, a bottom membrane installed above the floor, a prefabricated component template installed on both sides of the bottom membrane, a \turn\ section steel installed between the bottom membrane and the prefabricated component template, an \turn\ section steel opening facing outside, and a rubber sea arranged inside the \turn\ section steel. Vertical channel steel is installed on the outside of prefabricated component formwork. The prefabricated component formwork is fixed on the vertical channel steel by a number of supporting I-beams. A number of transverse I-beams are installed on the outside of the vertical channel steel. The top of the vertical channel steel on both sides is connected by the top-to-pull screw. The bottom-to-pull screw is installed on the bottom of the vertical channel steel, and the bottom-to-pull screw is pierced through. The vertical channel steel on both sides is connected inside the bottom-crossing membrane; the slurry stopping effect of the utility model is very obvious, the rubber sponge strip can be replaced at any time according to the wear condition, and the slurry stopping strip can also ensure that the prefabricated components and formwork do not remain, and that the prefabricated components and formwork are smooth and smooth, so the utility model has a very broad application and popularization prospect.

技术介绍
目前,在港口工程、水利工程和桥梁市政等工程中,经常会遇到预制梁、预制板等混凝土预制构件施工,一般工程上预制梁、板等混凝土构件都会在预制厂设置专门的底胎膜,再通过侧模与底胎膜相紧靠以减少该处漏浆的缺陷,但由于模板与底胎膜都属硬质材料,很难做到完全消除漏浆的情况。随着工艺的改进,进一步采取止浆等措施设置在拼缝处,但止浆条会因局部模版变形而失效,以及会黏贴在混凝土构件或模板表面的现象,处理起来难于清除。由于预制数量大,一般都成百上千件,因此,现场常规按照类似工厂生产线一样预制生产,采取若干条预制生产线生产,所谓的生产线就是根据预制构件几何形状,预先制作一定的基础台座,台座即底胎膜,一般突出地坪一定高度,常为混凝土结构,再把预制构件侧模底部紧靠底胎膜,即所谓的“墙包底”,拧紧对拉螺栓,让侧模与底胎膜紧密接触,这样减少浇筑混凝土过程中漏浆的程度,后来,为了进一步解决预制构件底部漏浆问题,又采取了粘帖式止浆海绵条措施,即在预制构件侧模与底胎膜接触面之间粘帖一层或两层止浆海绵条,拧紧对拉螺栓,相对前者来说,止浆效果得到了明显改善,但由于止浆海面条被对拉螺栓紧固力长时间压缩及本身具有的粘结性,往往会在拆模后止浆海绵条会粘结在模板上,或者粘结在混凝土构件上,甚至嵌入混凝土构件内部,混凝土构件容易存在烂根、底部蜂窝、麻面等漏浆造成的缺陷,既影响了预制构件外观质量,又降低了混凝土表面质量和耐久性能,影响模板的表面平整度,处理起来也比较麻烦,达不到理想的效果,特别对 ...
