Pre-tensioning method prestressed hollow slab umbrella support splicing type core mold and construction technology thereof
The invention discloses a pre-tensioning method prestressed hollow slab umbrella support splicing type core mold and a construction technology thereof. The construction technology comprises the steps of formwork designing and manufacturing, core mold splicing, steel strand tensioning, bottom plate and web steel bar binding, core mold installation, top plate steel bar binding, side mold installation, concrete pouring, formwork dismantling, maintenance, steel strand releasing and tensioning, plate girder hoisting and storage. The pre-tensioning method prestressed hollow slab umbrella support splicing type core mold comprises a plastic outer mold, rectangular steel pipes, a supporting mechanism and a fastening binding band. In the core mold combining and splicing process, supporting is carried out through the supporting mechanism, the rectangular steel pipes are bound through the fastening binding band from the outside, and after concrete is formed, an umbrella support type support is pulled to remove an internal support; then the rectangular steel pipes are removed one by one for demolding, so that control is more convenient in the construction process; meanwhile, the rectangular steel pipes and the supporting mechanism can be reused, two layers of plastic films are used for integrally winding and wrapping the core mold, and adhesive tape is used for firm bonding; and meanwhile, the plastic films are prevented from wrinkling.
本发明公开了一种先张法预应力空心板伞撑拼片式芯模及其施工工艺，包括模板设计制作、芯模拼装、钢绞线张拉、底板、腹板钢筋绑扎、芯模安装、顶板钢筋绑扎、侧模安装、混凝土浇筑、模板拆除、养护、钢绞线放张、板梁的起吊、存放，一种先张法预应力空心板伞撑拼片式芯模，包括塑料外膜、矩形钢管、支撑机构、紧固绑带，本发明芯模组合拼装过程中，通过支撑机构进行支撑，外部通过紧固绑带对矩形钢管捆绑，混凝土成型后通过抽拉伞撑式支架移除内部支撑，再逐根移除矩形钢管脱模，使得在施工过程中更加方便控制，同时矩形钢管和支撑机构均可重复利用，使用两层塑料膜将芯模进行整体缠绕包裹，并使用胶带粘结牢固，同时防止塑料膜起皱。
