Abstract
The invention provides a floor penetrating and anchoring type overhanging unloading steel platform and relates to a floor anchoring technology. Operation platforms are laid on two bearing steel beams of the outer side of a floor. Two rows of straight casing pipes are respectively and vertically embedded in the floor. A bolt is arranged in each casing pipe in a penetrating mode. The two bolts in each set of casing pipes above the floor are arranged on the same steel plate in a penetrating mode. The two bolts on the steel plate are connected with nuts respectively. The two bolts in each set of the casing pipes of the back of the floor are arranged on the same steel plate in a penetrating mode. The two bolts on the steel plate are connected with the nuts respectively. The bearing steel beams are arranged in the space formed by the two bolts in each corresponding row of casing pipes, the floor and a first steel plate in a penetrating mode. The four nuts of the tightening bolts have the tightening effects, and therefore potential safety hazards due to looseness are eradicated; moreover, the bolts are back-arranged fastening parts, and therefore laitance pollution generated in the concrete pouring process can be eradicated; the bolts arranged on the floor in the penetrating mode are convenient to anchor and disassemble, and therefore circulation use can be achieved.
Description
Technical field
The present invention relates to the technical field that a kind of cantilever steel platform for material unloading through-flooring carries out anchoring.
Background technology
In building engineering construction, generally can adopt cantilever steel platform for material unloading as the middle amboceptor of picking material and transhipment material, to improve the efficiency of construction.Cantilever steel platform for material unloading be generally by i iron end and floor be fixed, thereby i iron head end and wire rope carry out stretch-draw and form the stressed girder steel of encorbelmenting, and finally on girder steel, lays the operating platform system that steel plate forms.What in engineering, the i iron end of cantilever steel platform for material unloading and floor were fixed employing at present is the method for pre-buried round steel clip (or round steel bolt) in cast-in-situ concrete.Use this fixing means to exist following shortcoming:
1, before floor concrete casting, after using round steel clip to be connected with floor bar as built-in fitting, prop up immediately, the vibration producing when concreting is easy to cause the clip inclination that misplaces on horizontal plane and vertical plane, finally cannot use.In addition, in the time that clip produces horizontal plane absolute altitude error, cannot naturally tighten up flexibly fixingly with i iron while connection, can only clog timber wedge and carry out fasteningly, but timber wedge easily becomes flexible and makes potential safety hazard larger.
2, before floor concrete casting; in the time using pre-buried round steel bolt as built-in fitting; although comparing the follow-up problem of tightening up of pre-buried clip is resolved; but still the shortcoming that exists dislocation to tilt; and the laitance that the screw thread of bolt produces while being easy to by concreting pollutes, so the protection of screw thread has also been become to a large difficult point.
3, adopt the method for pre-buried round steel clip (or round steel bolt) cannot recycle after discharging platform is removed, in the cost control of engineering, caused very large waste.
In sum, the i iron end of cantilever steel platform for material unloading and floor adopt the method for pre-buried round steel clip (or round steel bolt) to exist many hidden danger, are unfavorable for engineering safety, quality, progress and cost control.
Summary of the invention
The present invention seeks to as addressing the above problem, propose a kind of through-flooring anchoring type cantilever steel platform for material unloading.
The present invention includes that two one end are arranged in floor top, the other end stretches out the load-bearing girder steel in floor outside, on two load-bearing girder steels in floor outside, lay operating platform, it is characterized in that vertical pre-buried two arranging straight shape sleeve pipe respectively on floor, every bar casing tube has two groups at least, every group is two, spacing between described two sleeve pipes of every group of sleeve pipe is greater than the width of load-bearing girder steel, and the described two load-bearing girder steels above floor are corresponding respectively to be arranged with two bar casing tubes; In each sleeve pipe, place respectively a bolt, two bolts in each group sleeve pipe of floor top are also set on same the first steel plate, difference attaching nut on two bolts on the first steel plate; Two bolts in each group sleeve pipe at floor back are also set on same the second steel plate, difference attaching nut on two bolts on the second steel plate; Each root load-bearing girder steel is set in the space that two bolts, floor and the first steel plate in each group sleeve pipe of a corresponding bar casing tube surround simultaneously.
The present invention adopts cantilever steel platform for material unloading through-flooring to carry out the method for anchoring, when construction pre-buried sleeve pipe due to from heavy and light, thereby vibrating load that body is little to be produced while being subject to concreting hardly affects, verticality and the levelness in the built-in pipe hole of formation are guaranteed; Because four nuts for tightening bolt all can play the effect of tightening up, so can make load-bearing girder steel lean on mutually with floor tightly completely by the degree of tightness of adjusting nut, stopped the security hidden trouble existing because of degree of tightness, and bolt is that the laitance that rearmounted securing member can produce while having stopped concreting pollutes; Due to this bolt anchoring convenient disassembly that is set in floor, the bolt ironware of use can repeat turnover and use, and has really accomplished engineering cost saving.
In addition, the present invention is also at parallel welding one block plate of a side of load-bearing girder steel, between load-bearing girder steel and described steel plate, jack is set, the vertical rigidity latch of planting in described jack, the lower end of described rigidity latch stretches out in the lower end of load-bearing girder steel, and the lower end of described rigidity latch contacts at the outside end face of floor.The present invention is owing to being provided with latch, and the inside horizontal force of floor platform better, has stopped the security hidden trouble existing because of degree of tightness.Adopt the method for this kind of anti-inside slippage can conscientiously ensure that anti-skidding firmware and cantilever steel girder are in same horizontal plane, the cantilever steel girder finished product of making is put and is transported more for convenience.
