Abstract
The invention discloses a cantilever scaffold steel girder anchoring method. The method comprises the following steps: after the mounting of a concrete floor bottom die and before the pouring of concrete, fixing a casing pipe on a casing pipe base so as to form a pre-buried pore forming device, and fixing the pre-buried pore forming device at a cantilever scaffold steel girder anchoring position; after the solidification of the concrete, forming two pores which are vertical to a floor; screwing a nut into the upper surface of the floor, screwing a nut into the lower surface of the floor, and after aligning the position of an anchoring bolt, screwing the nuts on the upper and lower surfaces of the floor at the same time so as to fix a steel girder on the floor; and when dismounting is needed after the construction, unscrewing the nut at any one of the upper and lower ends of the anchoring bolt so as to rapidly dismount the anchoring bolt without taking the pre-buried pore forming device out from the floor. Through the casing pipe base, the casing pipe can be vertical to the floor all the time and does not tilt during the pre-burying; the mounting and dismounting are convenient and the connection is stable, so that the construction safety can be ensured; and the method can be repeatedly used, so that the materials are saved, the labor is greatly saved and the working efficiency is improved.
Description
Technical field
The present invention relates to a kind of builder's jack girder steel anchoring process, 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 builder's jack girder steel anchoring process。
For achieving the above object, the technical solution used in the present invention is: a kind of builder's jack girder steel anchoring process, comprises the steps:
Step 1: according to actual requirement of engineering, calculate anchorage length and the specification of anchor bolt, position and the quantity of builder's jack girder steel, so as to meet stress and detailing requiments, and then determine the size of pre-buried hole-forming device, position and quantity。
Step 2: after concrete floor bed die is installed, before concreting, sleeve pipe is fixed on sleeve pipe base, forms pre-buried hole-forming device, be fixed on the anchorage point place of builder's jack girder steel；During casting concrete floor, the sleeve position keeping pre-buried is stable, after concrete setting, forms two pore-formings being perpendicular to floor；
Step 3: meet after installation foot hand cradle intensity until concrete strength, cantilever steel girder is placed by design attitude, inserting anchor bolt from floor upper surface, described anchor bolt is respectively successively from being provided with the angle steel pressing plate of through hole, sleeve pipe and sleeve pipe base traverse, and passes from underfloor surface；
Step 4: screwing in nut then the lower surface screw-in nut at floor from the upper surface of floor, behind the position of levelling anchor bolt, girder steel can be fixed on floor by the upper and lower surface of floor tightening nut simultaneously；
Step 5: construct complete need remove time, unscrew the nut of the upper and lower either end of crab-bolt, quickly anchor bolt can be unloaded, remove cantilever steel girder；
Step 6: adopt pea gravel concreten to irrigate closely knit by the anchor bolt reserving hole channel in floorslab concrete。
Preferably, before casting concrete floor, at described sleeve surface brushing interleaving agent。
Preferably, described 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。

In figure, 1. sleeve pipe, 2. sleeve pipe base, 3. floor, 4. anchor bolt, 5. angle steel 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 it is shown in figure 1, builder's jack girder steel anchoring process comprises the steps:
Step 1: according to actual requirement of engineering, calculate anchorage length and the specification of anchor bolt, position and the quantity of builder's jack girder steel, so as to meet stress and detailing requiments, and then determine the size of pre-buried hole-forming device, position and quantity。
Step 2: after concrete floor bed die is installed, before concreting, sleeve pipe 1 is fixed on sleeve pipe base 2, forms pre-buried hole-forming device, be fixed on the anchorage point place of builder's jack girder steel；During casting concrete floor, keep pre-buried sleeve pipe 1 position stability, after concrete setting, form two pore-formings being perpendicular to floor；
Step 3: meet after installation foot hand cradle intensity until concrete strength, by design attitude placing steel beam 6, inserting anchor bolt 4 from floor 3 upper surface, described anchor bolt 4 is respectively successively from being provided with the angle steel pressing plate 5 of through hole, sleeve pipe 1 and sleeve pipe base 2 traverse, and passes from floor 3 lower surface；
Step 4: screwing in nut 7 then the lower surface screw-in nut 7 at floor 3 from the upper surface of floor 3, behind the position of levelling anchor bolt 4, girder steel 6 can be fixed on floor 3 by the upper and lower surface of floor 3 tightening nut 7 simultaneously；
Step 5: construct complete need remove time, unscrew the nut 7 of the upper and lower either end of crab-bolt, can quickly anchor bolt 4 be unloaded, remove girder steel 6, pre-buried hole-forming device is embedded in floor 3 and does not take out；
Step 6: adopt pea gravel concreten to irrigate closely knit by the anchor bolt reserving hole channel in floor 3 concrete。
Preferably, before casting concrete floor 3, at described sleeve pipe 1 external coating interleaving agent。
Preferably, in order to ensure to combine closely between sleeve pipe 1 energy and surrounding concrete, described sleeve pipe 1 surfaces externally and internally is coarse。Due to sleeve pipe 1 rough inner surface, 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。
