Abstract
The utility model discloses a tensioning equipment, stretch-draw operation is with low costs and convenient to use. The tensioning device comprises a tensioning jack and a frame, wherein a chain block is arranged at the top of the frame, and the chain block is connected with the tensioning jack in a hooking mode. In order to facilitate the movement of the tensioning device and improve the efficiency of tensioning operation, a travelling mechanism, such as a wheel, can be arranged at the bottom of the frame.
Description
Technical field
The utility model relates to the tensioning equipment that a kind of building field is used.
Background technology
In the prior art; Usually need carry out stretch-draw to the isostructural tendon of beam slab that concreting forms; Need set up scaffold earlier during stretch-draw; Hanging the stretch-draw jack moved to through small-sized gantry then needs the tendon of stretch-draw position, and then the stretch-draw jack is linked to each other with tendon, implements the stretch-draw operation.Adopt above-mentioned stretching construction mode to have following deficiency, before the stretch-draw operation, need set up scaffold, after the stretch-draw end of job, need to remove scaffold, waste time and energy, the cycle of stretch-draw operation is longer, and efficient is low; Owing to generally have a plurality of tendons on the structures such as beam slab that concreting forms; Therefore need move the stretch-draw jack according to the tendon position; Move the stretch-draw jack owing to hanging in the prior art through small-sized gantry; Higher and the small-sized gantry of cost hangs and need take bigger work plane, uses very inconvenience.
The utility model content
The technical problem that the utility model solves provides a kind of stretch-draw operating cost tensioning equipment low and easy to use.
The utility model solves the technical scheme that its technical problem adopted: tensioning equipment, comprise the stretch-draw jack, and also comprise framework, the top of said framework is provided with Chain block, and said Chain block is connected with said stretch-draw jack hook.
Further be: the bottom of said framework is equipped with walking mechanism.
Further be: said walking mechanism is a wheel.
The beneficial effect of the utility model is: can significantly reduce the cost of stretch-draw operation through using Chain block handling stretch-draw jack, and Chain block is easy to use, and can be according to the position of actual conditions with stretch-draw jack fast moving to the tendon of needs stretch-draw.
Description of drawings
Fig. 1 is the sketch map of the tensioning equipment of the utility model.
Be labeled as among the figure: 1-Chain block, 2-stretch-draw jack, 3-framework, 4-wheel, 5-tendon.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further specified.
As shown in Figure 1, the tensioning equipment of the utility model comprises stretch-draw jack 2, also comprises framework 3, and the top of said framework 3 is provided with Chain block 1, and said Chain block 1 is connected with said stretch-draw jack 2 hooks.
During use, can through Chain block 1 stretch-draw jack 2 is moved to the tendon 5 that needs stretch-draw near, carry out stretch-draw through 2 pairs of these tendons 5 of stretch-draw jack then.
For the ease of fast moving said frame 3, improve the stretch-draw efficiency of operation, the bottom of said framework 3 is equipped with walking mechanism.Above-mentioned walking mechanism can be go-cart, just framework is arranged in the go-cart, and for simplified structure, said walking mechanism is a wheel 4.Through walking mechanism is set; When the tendon on the concrete structure after all stretch-draw finishes; Can framework be needed near the concrete structure of stretch-draw through walking mechanism fast moving to the next one; Through Chain block the stretch-draw jack is moved to the next door of the tendon that needs stretch-draw then, carry out the stretch-draw operation.Can know by above analysis, be provided with walking mechanism after, can significantly improve the stretch-draw efficiency of operation.
