Abstract
The invention discloses an anchoring device for a cantilever scaffold steel beam. The anchoring device comprises two pre-buried perforating devices symmetrically arranged in a floor slab in a spaced mode. Each pre-buried perforating device comprises a casing pipe and a casing pipe base. Each casing pipe base is pre-buried in the floor slab structure. Each casing pipe is perpendicular to the floor slab and installed on the corresponding casing pipe base. Two anchor bolts sequentially penetrate through a pressing plate, the casing pipes and the casing pipe bases to fix the steel beam to the floor slab, wherein the pressing plate is provided with through holes. According to the anchoring device for the cantilever scaffold steel beam, the effect that the casing pipes are always perpendicular to the floor slab is ensured through the casing pipe bases, and when pre-buried, the casing pipes are not toppled and inclined; assembling and disassembling are convenient, connecting is stable, and construction safety can be ensured; and repeated use can be achieved, materials are saved, the labor force is substantially saved, and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of steel girder anchoring device of overhanging scaffold, belong to building structure technology field.
Background technology
Recent two decades comes, and along with developing rapidly of China's building trade, building structure advances towards higher, more complicated form, and high level, irregular building structure are increasing, and overhanging scaffold ensures often and the necessary requirement of its smooth construction makes consumption huge.Wherein, in builder's jack, the anchoring of girder steel is again the key ensureing builder's jack safety.At present, the anchoring process of most traditional builder's jack girder steels mostly is and adopts crab-bolt cast-in-place among concrete floor.Crab-bolt can only single use, and use complete after also to take a lot of work the Partial Resection beyond floor.The method not only wastes great deal of steel, and a large amount of human and material resources are also wasted in the excision of unnecessary crab-bolt.
Summary of the invention
For above-mentioned prior art Problems existing, it is an object of the invention to provide a kind of stable connection, it is possible to repeatedly use, crab-bolt is installed simple, removes convenient steel girder anchoring device of overhanging scaffold.
For achieving the above object, the technical solution used in the present invention is: a kind of steel girder anchoring device of overhanging scaffold, two pre-buried hole-forming devices in floor it are symmetricly set on including interval, described pre-buried hole-forming device includes a sleeve pipe and a sleeve pipe base, described sleeve pipe base is embedded in floor construction in advance, described sleeve pipe is perpendicular to floor and is arranged on sleeve pipe base, and girder steel, respectively successively from being provided with the pressing plate of through hole, sleeve pipe and sleeve pipe base traverse, is fixed on floor by two anchor bolts.
Preferably, described sleeve pipe is PVC sleeve pipe.
Preferably, described PVC sleeve pipe surfaces externally and internally is coarse.
The sleeve pipe base of the present invention ensure that sleeve pipe is perpendicular to floor all the time, and will not skew time pre-buried inclination；Installation and removal are convenient, stable connection, it is possible to ensure construction safety；Can repeatedly use, save material, and significantly saved labour, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure, 1. sleeve pipe, 2. sleeve pipe base, 3. floor, 4. anchor bolt, 5. pressing plate, 6. girder steel, 7. nut.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of steel girder anchoring device of overhanging scaffold, two pre-buried hole-forming devices in floor it are symmetricly set on including interval, described pre-buried hole-forming device includes a sleeve pipe 1 and a sleeve pipe base 2, described sleeve pipe base 2 is embedded in floor 3 structure in advance, described sleeve pipe 1 is perpendicular to floor 3 and is arranged on sleeve pipe base 2, two anchor bolts 4 pass from being provided with the pressing plate 5 of through hole, sleeve pipe 1 and sleeve pipe base 2 respectively successively, nut 7 screws in from anchor bolt 4 two ends, is fixed on floor 3 by girder steel 6.
Preferably, described sleeve pipe 1 is PVC sleeve pipe.
Preferably, in order to ensure to combine closely between PVC sleeve pipe and surrounding concrete, described PVC sleeve pipe surfaces externally and internally is coarse.
After concrete floor bed die is installed, before concreting, two pre-buried hole-forming devices are fixed on the anchorage point place of builder's jack girder steel, form two pore-formings being perpendicular to floor, during installation, two anchor bolts 4 are respectively successively from being provided with the pressing plate 5 of through hole, sleeve pipe 1 and sleeve pipe base 2 traverse, then screwed in from anchor bolt 4 two ends by nut 7 and can fix.When building completion needs dismounting scaffold, reversely being screwed out by nut 7, extract anchor bolt 4, pre-buried hole-forming device is embedded in floor 3 and does not take out.Anchor bolt 4 adopts pea gravel concreten grout closely knit after removing, owing to PVC internal surface of casing is coarse, it is possible to combine closely with the pea gravel concreten poured into, thus the damage that concrete floor is caused reaches minimum.This device convenient disassembly, it is possible to repeatedly use, saves material；Unnecessary part need not be excised, saved manpower and materials.
Claims (3)
1. a steel girder anchoring device of overhanging scaffold, it is characterized in that, two pre-buried hole-forming devices in floor it are symmetricly set on including interval, described pre-buried hole-forming device includes a sleeve pipe and a sleeve pipe base, described sleeve pipe base is embedded in floor construction in advance, described sleeve pipe is perpendicular to floor and is arranged on sleeve pipe base, and girder steel, respectively successively from being provided with the pressing plate of through hole, sleeve pipe and sleeve pipe base traverse, is fixed on floor by two anchor bolts.
