Abstract

The utility model provides a specific lifting tool for a U-shaped shell mold of a huge prestress cover beam. The specific lifting tool comprises a main beam and at least two secondary beams, wherein the main beam is in a rectangular frame structure, at least two secondary beams are vertically bridged at the middle of the main beam, and lifting point holes are formed in tip parts, stretching out of the main beam, of the secondary beams; connecting screw rods are arranged between the lifting point holes of the secondary beams and lifting point holes in a lifting wall of a cover beam shell in a penetrating manner, and spherical nuts and gaskets are respectively arranged at the upper and lower ends of the connecting screw rods. The specific lifting tool has the beneficial effects that the construction timeliness of the cover beam can be increased, the whole lifting process lasts for about 1-2 hours, and the specific lifting tool is convenient to dismount and mount, is safe and efficient and is convenient, rapid and simple to maintain; and a lifted object is unlikely to fall and cannot overturn, so that the safety of the specific lifting tool is high.

Description

The U-shaped shell mould of huge Prestressed Slab Beams special hanger

Technical field

The utility model relates to a kind of oxygenerator, specifically the U-shaped shell mould of a kind of huge Prestressed Slab Beams special hanger.

Background technology

Generally coordinate suspender to come lifting beam or other relevant beams with two gantry in civil engineering industry, the suspender using in engineering at present all has shortcoming separately, as operates cumbersome simple and easy not; Clamping insecure, safe reliability is poor; Complex structure, cost are high, maintenance difficult etc.

Summary of the invention

For the above-mentioned deficiency of prior art, the utility model provides a kind of U-shaped shell mould of huge Prestressed Slab Beams special hanger quick and easy and easy to repair.

The U-shaped shell mould of a kind of huge Prestressed Slab Beams special hanger, comprise girder, at least two secondary beams, described girder is rectangular frame structure, the medium position of girder vertically sets up at least two secondary beams, the medium position of girder vertically sets up at least two secondary beams, the end portion that secondary beam stretches out girder is provided with suspension centre hole, and the end portion that secondary beam stretches out girder is provided with suspension centre hole; The suspension centre hole of secondary beam and bent cap shell rise between the suspension centre hole on hanging screen and are equipped with connecting screw rod, and the top and bottom of connecting screw rod are respectively equipped with spherical nut and pad.

The U-shaped shell mould of huge Prestressed Slab Beams as above special hanger, the length of girder is 14.8-15m.

The U-shaped shell mould of huge Prestressed Slab Beams as above special hanger, girder and secondary beam are welded by I-beam section.

The utility model can improve the timeliness of Coping Construction, the about 1-2 hour of whole handling process duration, and easy accessibility, safe and efficient, and keep in repair convenient, simple; Hanging object difficult drop-off, overturn-preventing, safe.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.

Please refer to Fig. 1-3, the U-shaped shell mould of the huge Prestressed Slab Beams of the utility model special hanger comprises girder 1, at least two secondary beams 2, described girder 1, secondary beam 2 are welded by I-beam section, its middle girder 1 is rectangular frame structure, the medium position of girder 1 vertically sets up at least two secondary beams 2, has four secondary beams 2 in embodiment illustrated in fig. 1.Stretch out from the sidewall of girder 1 at the two ends of secondary beam 2, and the end portion that secondary beam 2 stretches out girder 1 is provided with suspension centre hole 4, and embodiment illustrated in fig. 1 have eight suspension centre holes 4.On four angles of described girder 1, be respectively equipped with crane hoisting ring 3.

Please also refer to Fig. 4, the utility model also comprises the connecting screw rod 5 for connecting secondary beam 2 and bent cap shell 7, spherical nut and the pad 6 of locking connecting screw rod 5.Preferably, can be tight by 4 connecting screw rod 5 anchorings between secondary beam 2 and bent cap shell 7, each connecting screw rod 5 stretches out the suspension centre hole on

suspension centre hole

4 and 7 hanging screens of bent cap shell of termination of girder 1 through secondary beam 2 successively, connecting screw rod 5 is respectively equipped with spherical nut and pad 6 up and down, when stressed in lifting moment like this, make suspension rod have certain Anti-inclining ability.Concrete, connecting screw rod 5 lower ends are tight with the suspension centre hole anchor on 7 hanging screens of bent cap shell by shape nut and pad 6, by tight by spherical nut and pad 6 anchors to connecting screw rod 5 tops and secondary beam 2, the lifting of simultaneously having lifted by crane bent cap shell 7 by two gauntrys crane moves beam operation equally.The length of girder 1 is 14.8-15m, can meet the requirement that two gauntrys crane lift by crane simultaneously.Fig. 5 and Fig. 6 are respectively the schematic diagram that utilizes the middle sections of special hanger handling bent cap shell of the present utility model (being the U-shaped shell mould of huge Prestressed Slab Beams) and margin knot section.

The utility model is after handling completes, by unclamping upper and lower spherical nut, can be automatically loose from hanging object, there is the features such as easy to operate simple, simple structure, lifting be stable, easy to maintenance, the about 1-2 hour of whole handling process duration, compare existing lifting device dismounting more convenient, and safe and efficient, keep in repair convenient, simple, also difficult drop-off of hanging object in handling process, overturn-preventing, safe.
