Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1 and Figure 2, a kind of reinforcement installation servicing unit for Bridge High-pier construction, comprise the channel-section steel 1 that two specifications are consistent, relatively affixed dorsad bottom described two channel-section steels 1 is the integrative-structure of cross section in " H " font, be interrupted bottom channel-section steel 1 and be provided with at least one groove 3, described groove 3 is provided with straight screw sleeve 2.Select two channel-section steels 1, the reinforcing bar mainly considering simultaneously to lift by crane many 9m can make a channel-section steel 1 produce deformation, and two channel-section steels 1 are by being relatively fixed in the bending resistance that some can increase channel-section steel 1 dorsad, ensure that the vertical bury pipe of reinforcing bar hangs in institute, are convenient to installation.And channel-section steel 1 is not limited to welding manner herein, also connect by bolt or other modes; Described channel-section steel is also provided with the through hole 5 channel-section steel 1 level sling by rope, and through hole 5 is for passing wire rope or suspension hook, and through hole 5 slightly to channel-section steel 1 off-centring, can be too near to channel-section steel 1 edge to avoid through hole 5 and make through hole 5 load-bearing generation deformation.
Embodiment 2
Consistent with perpendicular bisector direction on the perpendicular bisector that described groove 3 is located at minor face bottom channel-section steel 1, groove 3 arranges 10 ~ 20, and between groove 3, spacing distance is 30mm ~ 70mm; Between groove 3, spacing distance is 50mm; In work progress, the spacing that different local main muscle requires is inconsistent.For ensureing that main muscle spacing is adjustable and selecting the main muscle of different size size, described groove 3 length is 60 ~ 140mm, and groove 3 is wide is 20mm ~ 40mm; Preferably groove 3 is long is herein 100mm, and groove 3 is wide is 33mm; Groove 3 can be arranged according to the length of channel-section steel 1 as far as possible more; At present, in road and bridge construction, that main muscle use is more is 32mm, the wide groove of 33mm 3 is set herein and can makes main muscle just through groove 3, and the external diameter adapting to the straight screw sleeve 2 of the main muscle of 33mm is obviously greater than 33mm, like this, straight screw sleeve 2 is just suspended on the two ends on the long limit of groove 3, thus cable wire is sling by tower crane, and then sling whole device, as shown in Figure 3 state.
Embodiment 3
The graduation mark 4 consistent with channel-section steel 1 length direction is also provided with at the side of described groove 3; Wherein graduation mark 4 can be arranged continuously along the length direction of channel-section steel 1; Graduation mark 4 also only can be interrupted setting at the side of groove 3 along the length direction of channel-section steel 1, and every section of graduation mark 4 is consistent with the length on each long limit of groove 3.In work progress, the pitch requirements of zones of different to main muscle is different, when this spacing changed by needs, spacing size can be again demarcated according to graduation mark 4 below building, and the straight screw sleeve 2 of socket reinforcing bar is adjusted to relevant position, facilitate the operation of constructor above building like this.
In sum, specific works process of the present utility model is as follows: first, below construction area, according to the spacing that main muscle arranges, with reference to the graduation mark 4 on channel-section steel 1, main muscle is passed groove 3 and straight screw sleeve 2 of screwing on successively, then sling through the wire rope of groove 3 or suspension hook and then whole device of slinging together with reinforcing bar by tower crane, during in-position, reinforcing bar is connected with the straight screw sleeve 2 of below bottom, take off the straight screw sleeve 2 on device again, device is taken off from reinforcing bar, again the straight screw sleeve 2 taken off is screwed on reinforcing bar, so, the installation of next group reinforcing bar can be carried out.When converting the spacing of main muscle, again being demarcated by the graduation mark 4 on device below construction area and fixing the position of reinforcing bar, very convenient.
The above; it is only preferred embodiment of the present utility model; not do any pro forma restriction to the utility model, every any simple modification, equivalent variations done above embodiment according to technical spirit of the present utility model, all falls within protection domain of the present utility model.
