Anti-seepage building floor slab post-cast strip structure and pouring method

Abstract

The invention discloses an anti-seepage building floor slab post-cast strip structure. The anti-seepage building floor slab post-cast strip structure comprises a building formwork, wherein a second protective layer is arranged at the top end of the building formwork; a waterproof roll is arranged at the top end of the second protective layer; a first protective layer is arranged at the top end of the waterproof roll; a reinforced concrete layer is arranged at the top end of the first protective layer; a water-resistant plate is arranged at the top end of the reinforced concrete layer; an underground layer plate lower steel bar is arranged at the top end of the water-resistant plate; a first I-shaped steel bar support is arranged at the top end of the underground layer plate lower steel bar; a water-stop belt is arranged at the top end of the first I-shaped steel bar support; a second I-shaped steel bar support is arranged at the top end of the water-stop belt; a post-cast strip is poured between the second I-shaped steel bar support and the underground layer plate lower steel bar; closing net formworks are arranged in vertical construction joints on the two sides of the post-cast strip; and an underground layer plate upper steel bar is arranged at the top end of the post-cast strip. The anti-seepage building floor slab post-cast strip structure is reasonable and reliable in construction process, and the later-period seepage risk is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a post-cast belt structure and a pouring method for an anti-leakage building floor slab. Background technique [0002] According to the national standard: Article 2.0.10 of the construction specification for concrete structure engineering defines the post-pouring belt as: in order to adapt to environmental temperature changes, concrete shrinkage, uneven settlement of structures and other factors, it is placed on beams, slabs (including foundation slabs), walls, etc. The concrete belt with a certain width reserved in the structure and poured after a certain period of time. The design and construction of the post-cast belt structure is an important part of the construction project. Due to the particularity of its structure, higher requirements are put forward for design factors and construction techniques in actual construction; [0003] Conventional post-cast belt constructi...

AI Technical Summary

Problems solved by technology

[0003] Conventional post-cast belt construction usually pours reinforced concrete anti-compression slabs before binding the bottom plate steel bars, but this method has poor shear and bending resistance, which will cause cracks in the anti-compression slabs, and it will also affect the water stop on both sides of the post-pouring belt. The fixing effect is average, and it is easy to make the water stop belt deviate from the original position during construction, so there is a hidden danger of water seepage
