Die for manufacturing preformed hole
The invention relates to the technical field of building construction, in particular to a mold for manufacturing a preformed hole, which comprises an elastic body with a big upper part and a small lower part on the periphery, a radial breathing deformation groove in the longitudinal direction, and a sliding hole in the bottom; the operation assembly drives the sliding block to ascend, the elastic body expands and can drive the sliding block to descend, and the elastic body contracts. The maximum strain generated by stress in the concrete solidification process is absorbed through the elastic body. The sliding holes are matched with the sliding blocks, the bidirectional stress state of the mold structure in the concrete setting process is controlled, the radial breathing deformation grooves are designed in the mold body structure and serve as pre-acting reverse stress expansion space, and the effect of mutual stress in the concrete setting process is thoroughly achieved; in the demolding process, original interference fit is changed into clearance fit, so that the barbaric operation mode when an existing mold is taken out is avoided, damage to the periphery of the preformed hole is avoided, and the integrity and the appearance quality of the preformed hole are guaranteed.
本发明涉及建筑施工技术领域，具体涉及一种制作预留孔的模具，包括：弹性体外周上大下小，且沿纵向设有径向呼吸变形槽，底部设有滑孔；操作组件带动滑块上升，弹性体膨胀，且可带动滑块下降，弹性体收缩；本申请利用弹性体吸收混凝土凝固过程中应力产生的最大化应变。滑孔配合滑块，实现控制混凝土凝结过程中对模具结构的双向受力状态，在模具主体结构上设计径向呼吸变形槽，同时作为预作用反向应力膨胀空间，彻底解决混凝土凝结过程中相互之间应力的作用效果，脱模过程由原有的过盈配合变为间隙配合，从而避免现有模具取出时的野蛮操作方式，避免预留孔周边的破坏，保证预留孔的完整性和观感质量。
