Abstract

The in-situ deposited concrete hollow floor slab is characterized by that is consists of reinforced concrete and corruagated thin-wall tube fill-up member. The corrugated thin-wall tube fill-up member embedded in reinforced concrete is formed by hard thin-wall tube and two plugs to seal two ends of the hard thin-wall tube to form a closed hollow cavity. As compared with available in-situ thick floor slab said invention possesses the advantages of light self-weight, small reinforced concrete consumption, saving cost and good sound-insulating effect, convenient construction, strong quake-proof performance and convenient passing and mounting of water, electric and air-conditioner pipelines.

Description

Corrugated thin-wall hollow roof in-situ deposited with concrete
The invention belongs to the concrete cast-in-situ hollow building roof of industry and civil building.
Present common hollow building cover must the demoulding, can only be prefabricated can't be cast-in-place, generally only be suitable for the standard width of a room in an old-style house and the less building of span.When the building span is big, mostly adopt cast-in-place slab or close rib building roof.Cast-in-place thick reinforced concrete floor is from great, and the steel bar concrete consumption is big, and is uneconomical.Close rib building roof is put the mould difficulty and converts thickness of slab big, influences floor height, increases furred ceiling expense and template wear and tear expense.
The purpose of this invention is to provide a kind of convenient construction and transport, in light weight, be convenient to installation, rigidity is strong, pull resistance and crushing resistance are good, anti-vibration resistance is strong, and big with the concrete contact surface, bond stress is extremely strong, shear strength is big, seam is firm, does not thread off, sealing-off not spillage, impermeable corrugated thin-wall hollow roof in-situ deposited with concrete behind the cast-in-site.
The present invention is made up of steel bar concrete and corrugated thin-wall tube noggin piece, described corrugated thin-wall tube noggin piece is embedded in the steel bar concrete, the corrugated thin-wall barrel member is made up of horniness thin-walled tube and plug, and two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, and the hard thin-wall tube is a bellows.
Described its shape of cross section of corrugated thin-wall tube noggin piece can be circle, square or other shapes, and corresponding plug shape is identical with the horniness thin-walled tube shape of cross section.
Described horniness thin-walled tube can be formed by connecting by many bellowss.
Described steel bar concrete is the combining structure of prestressed reinforced concrete, reinforcing bar steel bar concrete, steel and steel bar concrete also.
The present invention is owing to adopt the structure of filling the corrugated thin-wall tube, make it to compare with existing cast-in-place thick reinforced concrete floor and have from heavy and light, the steel bar concrete consumption is few, cost saving, the advantage that soundproof effect is good, the present invention also has and fills corrugated thin-wall tube and concrete to contact bond stress extremely strong in addition, and shear strength is big, and seam is firm, do not thread off, and easy construction, quick, behind the cast-in-site not spillage, do not seep water, shock resistance is strong, is convenient to water power, air conditioning piping passes through advantages such as installation.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the embodiment of the invention one.
Fig. 2 is the left sectional view of the embodiment of the invention one.
Fig. 3 is the structural representation of the embodiment of the invention two.
Fig. 4 is the left sectional view of the embodiment of the invention two.
Fig. 5 is the positive view of the embodiment of the invention two.
Shown in Fig. 1~5, the present invention is made up of steel bar concrete 1 and corrugated thin-wall tube noggin piece 2, described corrugated thin-wall tube noggin piece 2 is embedded in the steel bar concrete 1, described corrugated thin-wall barrel member 2 is made up of horniness thin-walled tube 21 and plug 22,23, two plugs 22,23 form an enclosed cavity with horniness thin-walled tube 21 closed at both ends, horniness thin-walled tube 21 is a bellows among the present invention, and wherein Fig. 1,2 has provided embodiments of the invention one, and its horniness thin-walled tube 21 cross sections and plug 22,23 are shaped as circle.Fig. 3~5 have provided embodiments of the invention two, and its horniness thin-walled tube 21 cross sections and plug 22,23 are shaped as square.
Described horniness thin-walled tube can adopt metal, plastics manufacturing, as metal threaded pipe, plastic film capicitor etc.Described plug can be with the also available soft material manufacturing of hard material manufacturing (as metal, plastics etc.).Plug can installed and used preceding shrouded bellow, also can be when using the installation bellows, and shrouded bellow before the pour concrete.
