Abstract
The invention discloses a cast-in-place concrete hollow slab with a GRF box member fixed by a flat-ended internal threaded rod, and the cast-in-place concrete hollow slab belongs to constructional engineering. The slab comprises a flat-ended internal threaded rod, threaded rod forked hooks, a screw, a fixing lead wire, a compression bar, a GRF box body, reinforcing steel bars, a steel wire mesh piece and a formwork. The slab is characterized in that the GRF box body is tied and fixed through the flat-ended internal threaded rod which is fixed and vertically arranged on the formwork through the screw which penetrates through the formwork and the fixing lead wire which is sleeved with the threaded rod forked hook on the other end of the flat-ended internal threaded rod. Compared with the prior art, the slab has the advantages of simplicity in structure, easiness in production, convenience in use, low cost, accurate positioning, reliable fixing, no exposed bar end and wire end residues after form removal and the like; moreover, the forked threaded rod jacks and supports a steel reinforcement cage and, so that the steel reinforcement cage can be laid more standardly and accurately; the internal quality of a concrete structural body is improved; and consequently, the slab has good popularization and application values.
Description
One, technical field:
The invention belongs to construction work, a kind of tack internal thread screw rod fixes GRF box component cast-in-place concrete hollow floor slab specifically.
Two, background technology:
GRF box component is imbedded in the concrete of floor as internal mold, alleviates floor own wt, solve the large bay of building, large span, from heavy and light, Wu Mingliang and wide inclined beam, meet again the demand of building sound insulation, heat insulation, antidetonation, energy-conserving and environment-protective simultaneously, extensively approved by industry and apply.But ensure that GRF casing is stable on the locus of design in what measure of employing, there is no unified and standard, universally recognized engineering method.Apply more upper pressure, lower pull technology under prior art, also there is many technology differences and operation easier.Subject matter is: 1, be arranged on reinforcing cage body by the fulcrum of upper pressure, drop-down fixing GRF box component, when GRF casing gross buoyancy is greater than reinforcing cage body gross weight in cast, can shake the integral position of reinforcing cage body, forms quality accident; 2, be arranged at outside concrete structure by the fulcrum of upper pressure, drop-down fixing GRF lower box component, careless manipulation still can affect quality level, tears open to touch simultaneously and also brings many extra works, leave over many vestiges, broken end after form removal to the later stage; 3, rely on experience in fixing operation, tension and compression height distance is determined in range estimation, is difficult to accurate location more.
Three, summary of the invention:
The object of the invention is for above problem and shortage, a kind of easily operation is provided, accurate positioning, fixing reliable, fix GRF box component cast-in-place concrete hollow floor slab without the tack internal thread screw rod leaving over vestiges after form removal.
The object of the invention is to be achieved through the following technical solutions:
A kind of tack internal thread screw rod fixes GRF box component cast-in-place concrete hollow floor slab, it comprises tack internal thread screw rod, screw rod bifurcated is linked up with, screw, fixing galvanized wire, press strip, GRF casing, reinforcing bar, steel fabric sheet and template, it is characterized in that GRF casing is the screw by passing through template, fixed vertical is positioned over the tack internal thread screw rod in template, the fixing galvanized wire hitched is linked up with by the screw rod bifurcated of the tack internal thread screw rod other end, fasten knot press strip fixing, its tack internal thread screw rod one end is blind pipe internal thread, the other end is return the hook torn open after bifurcated, press strip is lengths of rebar or steel plate strip.Reinforcing bar is set in described pillar chamber, strengthens column strength, improve support force and life-span.
Described tack internal thread screw rod, it is characterized in that one end is blind pipe internal thread, the other end returns and curves hook, and solid pressure bar directly hung by its hook.
The present invention compared with prior art, have that structure is simple, easy to make, with low cost, operating specification, registration, fixing reliable, tear open and touch rear nothing and leave over and expose residual head, simultaneously the bifurcation structure of its tack internal thread screw rod other end more can bracket reinforcing cage be smooth is equidistantly suspended on soffit formwork face, steel mesh reinforcement is mated formation more specification, more accurate, improve the inherent quality of concrete structure, thus, the present invention has good value for applications.
Four, accompanying drawing illustrates:
Fig. 1 is the tack internal thread screw rod vertical section structure schematic diagram that tack internal thread screw rod fixes GRF box component cast-in-place concrete hollow floor slab.
Fig. 2 is that tack internal thread screw rod that tack internal thread screw rod fixes GRF box component cast-in-place concrete hollow floor slab is layouted schematic diagram.
Fig. 3 is the GRF casing anchoring partial cutaway schematic that tack internal thread screw rod fixes GRF box component cast-in-place concrete hollow floor slab.
In figure: 1. tack internal thread screw rod, 2. screw rod bifurcated hook, 3. screw, 4. galvanized wire, 5. press strip, 6.GRF casing, 7. reinforcing bar, 8. steel fabric sheet, 9. template.
Five, detailed description of the invention:
Below in conjunction with Figure of description, GRF box component cast-in-place concrete hollow floor slab is fixed to tack internal thread screw rod of the present invention and does following further detailed description:
As shown in Figure 1; according to the reinforcing cage lower protective layer thickness requirement that Building Design requires, intercept corresponding length round steel section, one end boring arch silk; other end welding round steel section or the curved screw rod bifurcated hook 2 splitted into as diagram shape of special prismatic spike, be combined into tack internal thread screw rod 1.
During use, as shown in Figure 2, in the floor backing template 9 of laying steel fabric sheet 8, according to size and the layout density line punching of the GRF casing 6 of designing requirement, pass through the vertical fixing tack internal thread screw rod 1 of boring with the standard component screw 3 of appropriate length, arrange lower floor's reinforcing bar 7, and be placed on the fork of screw rod bifurcated hook 2 through the reinforcing bar 7 of tack internal thread screw rod 1, ligation in length and breadth reinforcing bar 7 joint becomes net, arranges GRF lower box 6, and on adjacent GRF casing 6, middle part arranges press strip 5.And be fixed on screw rod bifurcated hook 2 with fixing galvanized wire 4 extension.Laying longitudinally connects and top reinforcement 7 ligation joint and becomes cage, and the errorless rear laminated pouring concrete of prison receipts shocks closely knit.Concrete coagulates in fact, all screws 3 of removal, stripping.
Except the technical characteristic described in manual, be the known technology of those skilled in the art.
