Abstract
The utility model discloses a rear bolt anchoring system for a cantilever steel I-beam. The system is characterized by comprising two bolts, a fixed plate, nuts and a PVC (Poly Vinyl Chloride) sleeve; two ends of the bolts are threaded; the lower ends of the bolts penetrate through the PVC sleeve which is pre-buried in a concrete floor slab, and are fixed with the nuts by the fixed plate; and the steel I-beam is fixed between the parts of the two bolts above the concrete floor slab, and are fixed with the nuts by the fixed plate. Each nut is fixed by two nuts. The bolts adopt round steels with phi of 20; and the threaded lengths on two ends are respectively in a range from 70-75 mm. The fixed plate is a steel plate. The phi of the PVC sleeve is 25, and the PVC sleeve is vertically pre-buried. Compared with the traditional method of welding after pre-burying by applying round steel pressure rings, the rear bolt anchoring system for the cantilever steel I-beam disclosed by the utility model avoids the economic loss caused by inaccurate pre-burying of the round steel pressure rings, and has the obvious advantages of reduced risks in safety and technique, decreased unnecessary welding workload, quick construction speed, beautiful appearance, capacity of turnover use and the like.
Description
Technical field
The utility model relates to the realm of building construction, relates in particular to a kind of rearmounted bolt anchoring of the steel I-beam system of encorbelmenting in the steel I-beam anchoring construction of encorbelmenting.
Background technology
At present, highrise building is encorbelmented in the steel I-beam anchoring construction, conventional way is to adopt pre-buried, the way of welded limiting reinforcing bar again of round steel pressure ring, but builds the situation that pre-buried round steel off normal often occurs behind the floorslab concrete easily, cause pre-buried round steel pressure ring invalid with waste; On the other hand the welded limiting reinforcing bar occur pre-buried round steel excessively the situation of burn also happen occasionally.How to avoid round steel pressure ring off normal, the steel I-beam anchorage point that guarantees to encorbelment is accurate, and anchoring quality is reliable, guarantees that construction safety becomes common problem in the high-building construction.
The utility model content
Technical problem to be solved in the utility model provides a kind of rearmounted bolt anchoring of steel I-beam system of encorbelmenting, and has solved the problems referred to above.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of rearmounted bolt anchoring of steel I-beam system of encorbelmenting is characterized in that: comprise 2 bolts, fixed head, nut and PVC sleeve pipe; The equal mantle fiber in the two ends of described bolt, described bolt lower end pass the PVC sleeve pipe that is embedded in the concrete floor and fix with fixed head and nut; Steel I-beam is fixed on 2 bolts and fixes between the part on the concrete floor and by fixed head and nut.
The fixing double nut that adopts of described nut is fixed.
Described bolt adopts Ф 20 round steel, and two ends rod thread processing length respectively is 70-75mm.
Described fixed head is steel plate.
Described PVC sleeve pipe adopts Ф 25, and is vertically pre-buried.
The beneficial effects of the utility model:
The utility model uses round steel pressure ring way pre-buried, again welding to compare with tradition, avoided the pre-buried inaccurate economic loss that causes of round steel pressure ring, have that to reduce safety, technical risk, minimizing unnecessary welding job amount, speed of application fast, impression is attractive in appearance, can have enough to meet the need the obvious advantages such as utilization.
