Abstract
The utility model discloses a floor penetrating anchoring type overhang unloading steel platform, and relates to the floor anchoring technology. An operation platform is laid on two bearing steel beams outside a floor, two rows of straight sleeves are vertically embedded in the floor, a bolt is arranged in each sleeve in a penetrating mode, the two bolts in each set of sleeves on the floor are arranged on the same steel plate in a penetrating mode, and the two bolts in each steel plate are respectively connected with nuts; the two bolts in each set of sleeves on the back of the floor are arranged on the same steel plate in a penetrating mode, and the two bolts in each steel plate are respectively connected with nuts; each bearing steel beam is arranged in the space in a penetrating mode, wherein the space is defined by the bolts in all sets of sleeves of the corresponding row of sleeves, the floor and the first steel plates. The fastening effect can be achieved by fastening the four nuts of the bolts in each set of sleeves, and therefore potential safety hazards caused by looseness are eliminated; the bolts are fasteners arranged in the later period, and therefore laitance contamination caused during concrete pouring is eliminated; the bolts arranged on the floor in the penetrating mode can be conveniently anchored and detached, and can be repeatedly used.
Description
Technical field
The utility model 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 during concreting is easy to cause the clip inclination that misplaces on horizontal plane and vertical plane, finally cannot use.In addition, when clip produces horizontal plane absolute altitude error, cannot naturally tighten up flexibly fixingly while being connected with i iron, 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; when 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.
Utility model content
The utility model object is for addressing the above problem, and proposes a kind of through-flooring anchoring type cantilever steel platform for material unloading.
The utility model comprises 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 method that the utility model adopts cantilever steel platform for material unloading through-flooring to carry out 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 the degree of tightness by adjusting nut can make load-bearing girder steel lean on mutually with floor tightly completely, 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; Because this is set in the bolt anchoring convenient disassembly of floor, the bolt ironware of use can repeat turnover and use, and has really accomplished engineering cost saving.
In addition, the utility model 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 utility model is owing to being provided with latch, and the inside horizontal force of floor platform, has stopped the security hidden trouble existing because of degree of tightness better.Adopt the method for this kind of anti-inside slippage can conscientiously guarantee 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.
