Cast-in-place floor slab hogging moment rib variable-interval steel bar welding net and construction method
The invention discloses a cast-in-place floor slab hogging moment rib variable-interval steel bar welding net and a construction method, relates to the technical field of building construction, and aims to solve the problems that a plate surface welding net serving as hogging moment ribs is difficult to position during laying, and the thickness of a concrete protection layer is insufficient due tooverlapping of longitudinal and transverse ribs. The cast-in-place floor slab hogging moment rib variable-interval steel bar welding net comprises a surface net formed by welding a plurality of transverse reinforcing steel bars and longitudinal reinforcing steel bars which are perpendicular to each other, the surface net is laid on longitudinal high beams, longitudinal positioning holes are reserved in the surface net, the number of the longitudinal positioning holes is equal to that of the high beams spanned by the surface net, the positions of the longitudinal positioning holes in the surface net are consistent with those of the high beams, and the distance between the adjacent steel bars on two sides of each longitudinal positioning hole is consistent with the width of the high beam where the longitudinal positioning hole is located. The construction quality of the cast-in-place concrete floor slab hogging moment rib can be improved, meanwhile, steel can be reasonably saved, laboris reduced, the construction speed is increased, in addition, reinforcing steel bars of all face nets can be perfectly aligned, joints make contact with one another, and force transmission of stressedreinforcing steel bars is effective.
本发明公开了一种现浇楼板负弯矩筋多变间距钢筋焊接网及施工方法，涉及建筑施工技术领域，为解决作为负弯矩筋的板面焊网铺设时难定位且纵横筋重叠导致混凝土保护层厚度不足的问题；本发明包括多根横向及纵向相垂直的钢筋焊接成的面网，面网铺设在纵向的高梁上，面网上留有纵向定位空洞，其数量与面网跨越的高梁数量相等，纵向定位空洞在面网上的位置与高梁的位置一致，纵向定位空洞两侧相邻的钢筋之间的间距与其所在处高梁的宽度一致；本发明有利于提升现浇混凝土楼板负弯矩筋的施工质量，同时可以合理节约钢材，减少人工，加快施工速度，另外各面网的钢筋均可完美对齐，并且接头处相接触，让受力钢筋传力更有效。
