Hollow battens, ribbed floors using hollow battens and construction formwork systems

Abstract

The invention discloses a hollow slat, which is provided with a plurality of long core-pulling holes, the axial direction of the core-pulling holes is horizontal along the length direction, and the core-pulling holes are provided with plugs, or are reduced to small holes a at one end; the hollow The slats contain reinforcing ribs, and the sides are provided with embedded or pin-key connections or superimposed structures. The hollow slats are light insulated from sound, fire-proof and heat-preserving; the invention discloses a densely ribbed floor slab using hollow slats, including densely ribbed concealed beams and panels, and hollow slats, a plurality of hollow slats are arranged at intervals. Concrete is poured at the intervals and tops to form densely ribbed concealed beams and panels. The floor slab is convenient in construction, low in cost and good in performance; the invention discloses a construction formwork system using hollow slats, including joists and permanent formwork, both sides of the permanent formwork are supported on the edges of adjacent joists, and the permanent formwork is hollow slats , a plurality of hollow slats are arranged at intervals. The construction formwork system is quick to install and has no or few vertical supports.

Description

technical field [0001] The invention belongs to the technical field of construction and relates to hollow slats. The invention also relates to a densely ribbed floor slab using hollow slats. The invention also relates to a construction formwork system for building densely ribbed slabs and using hollow slats. Background technique [0002] Traditional cast-in-place concrete solid slabs have good integrity and durability, but they are heavy and use a lot of materials. Reinforced concrete ribbed slabs can save materials and reduce self-weight. Detachable plastic formwork (mold boxes) are often used for construction and molding, but the installation The demolition is complicated, the bottom surface of the formed floor is uneven, the panel is thin, and the sound insulation and heat insulation and fire resistance are poor. One of the improved methods is to use prefabricated hollow bricks, aerated concrete blocks, hollow pipes, formwork, etc. to fill, and cast in-situ to form a dens...

AI Technical Summary

Problems solved by technology

[0004] Hollow slats were originally used as internal partition walls, with large production capacity, mature technology, and relatively complete standards and specifications, such as national and industry standards "JC / T 829-2010 Gypsum Hollow Slats", "GB / T 23451-2009 Lightweight Partitions for Construction Wall slats, etc., but this type of product is only used as an interior partition wall material, and its use is limited

[0005] In addition, the densely ribbed floor still has the problem that the size of the rib beam and the position of the steel bar are not easy to be accurate, which needs to be improved

[0006] The construction formwork of the existing densely ribbed floor needs more vertical supports and formwork, such as the scaffolding support of the whole hall, and the formwork is fully paved, and the disassembly and assembly are time-consuming and laborious, and the efficiency is low
