Abstract
The utility model relates to a retainer for preventing the floating of BDF cast-in-situ concrete hollow floors. The retainer comprises a transverse retainer rod, a vertical retainer rod, curved retainer rods and a curved clamping hook, wherein both ends of the transverse retainer rod are connected with the curved retainer rods, the middle of the transverse retainer rod is connected with one end of the vertical retainer rod, and the other end of the vertical retainer rod is connected with the curved clamping hook. The retainer has the advantages that: the retainer is easy to operate and convenient to use, saves manpower, increases the production efficiency, and can bring significant economic and social benefits.
Description
Technical field
The utility model relates to a kind of stop, relates in particular to a kind of stop of the BDF of being used for cast-in-place concrete hollow building roof anti-floating.
Background technology
BDF cast-in-place concrete hollow building roof technology is that Ministry of Construction's energy and land saving type building is applied technology, the BDF hollow section is installed, should note when arranging hollow section is laid by unified direction, make the pipe justify align simultaneously, and the spacing that keeps every hollow section is 5cm, hollow section is the circular hollow tubular product of sealing, owing to will cause hollow section to produce bigger buoyancy under vibrating head and concrete acting in conjunction, handles so must carry out anti-floating to hollow section in the concrete placement.Use special-purpose stop spacingly to fix, reach good anti-floating effect.
The utility model content
The purpose of this utility model provides the effective stop that is used for BDF cast-in-place concrete hollow building roof anti-floating of a kind of anti-floating.
The technical solution adopted in the utility model is:
A kind of stop that is used for BDF cast-in-place concrete hollow building roof anti-floating, it is characterized in that: it comprises stop cross bar, stop montant, stop bow and arc folder hook, described stop cross bar two ends all are connected with the stop bow, described stop cross bar middle part is connected with stop montant one end, and the described stop montant other end is connected with arc folder hook.
Be equipped with control valve on described stop cross bar and the stop montant.
Advantage of the present utility model: the stop that is used for BDF cast-in-place concrete hollow building roof anti-floating is simple to operate, easy to use, saves manually, enhances productivity, and its economical, societal benefits are obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is user mode figure of the present utility model.
Wherein: 1, stop cross bar, 2, the stop montant, 3, the stop bow, 4, arc folder hook, 5, control valve, 6, hollow section, 7, the base plate reinforcing bar.
The specific embodiment
As shown in Figure 1, a kind of stop that is used for BDF cast-in-place concrete hollow building roof anti-floating of the present utility model, it comprises stop cross bar 1, stop montant 2, stop bow 3 and arc folder hook 4, stop cross bar 1 two ends all are connected with stop bow 3, stop cross bar 1 middle part is connected with stop montant 2 one ends, stop montant 2 other ends are connected with arc folder hook 4, are equipped with control valve 5 on stop cross bar 1 and the stop montant 2.
As shown in Figure 2, the concrete using method of stop: each stop is fixed two parallel hollow sections 6, the constructor inserts stop montant 2 between two hollow section 6 gaps, make the arc part of the arc part of stop bow 3 of stop montant 2 both sides and hollow section 6 agree with fully that (hollow section is made through special die sinking, so size one is touched the same, the condition of providing convenience for the use of large-scale production of stop), after treating that the position adjustment finishes, tip arc folder hook 4 parts of stop in base plate reinforcing bar 7, simultaneously according to size, by control valve 5 fine setting stop distances, hollow section 6 one ends are fixedly finished; Equally, the other end is also fixing in this way, and the hollow section 6 of each unit contains two stops to be fixed.
The stop that is used for BDF cast-in-place concrete hollow building roof anti-floating is simple to operate, and the material of stop is the PC(Merlon), the intensity of its existing metal, have both ductility and toughness simultaneously, easy to use, save artificial, enhance productivity, its economical, societal benefits are obvious.
