[0003](1)工序繁琐，效率低下：木模板工艺必须经过“支模→拆模→凿毛”多道工序，全部依赖人工，施工周期长，效率低

Benefits of technology

[0016] The technical solution provided by this utility model has the following beneficial effects: the folded part enhances the overall rigidity of the slab and its resistance to lateral concrete pressure; furthermore, the seepage holes allow cement slurry to permeate and migrate through the seepage holes during the first-stage concrete pouring, forming a coarse-grained interface on the second side of the slab. After the second-stage concrete pouring, the new and old concrete form a robust "locking" structure, with shear resistance far superior to ordinary roughened or simple mesh formwork structures; the anchor blocks allow them to be poured together during the first-stage concrete pouring, forming a mechanical anchoring structure that provides strong pull-out resistance; and the construction process is simple and efficient.

Abstract

The application discloses a dismounting-free metal formwork net for concrete staged pouring, relates to the technical field of building construction formworks, and comprises a plate body, the plate body comprises a folded part and flat parts, at least two flat parts are arranged, and the adjacent two flat parts are connected through the folded part; the folded part forms a convex structure relative to a first side face and forms a concave structure relative to a second side face; the folded part is provided with seepage holes at intervals; the flat parts are provided with pull anchor holes at intervals, the pull anchor holes are provided with pull anchor blocks, the two ends of the pull anchor blocks are connected at the edges of the pull anchor holes respectively, the circumferential edge part of the pull anchor hole is separated from the pull anchor block, and the pull anchor block is arched relative to the first side face. Through the arrangement of the folded part, the seepage hole and the pull anchor block, the overall rigidity of the plate body and the ability of resisting the lateral pressure of concrete can be enhanced, and strong pulling resistance can be provided; the construction process is simple and efficient.
