Abstract
The utility model discloses a prestressed steel belt with a tightening device, wherein the prestressed steel belt is provided with a fixed end and a free end; the fixed end is provided with a tightening device; the free end is provided with a plurality of through holes; the tightening device comprises a supporting frame, and a ratchet wheel and a wrench which are arranged in the supporting frame; the wrench is provided with pawls; the lower part of the supporting frame is provided with a jack through which the free end penetrates; and the ratchet wheel abuts against the pawls to lead ratchets of the ratchet wheel to be clamped in the through hole of the free end. In the prestressed steel belt with the tightening device, the tightening and the fixing can be conveniently realized on the prestressed steel belt simultaneously by the tightening device, so that good tightening effect is realized.
Description
Technical field
The utility model relates to a kind of prestressing force steel band, relates in particular to a kind of prestressing force steel band that has tightening device.
Background technology
The prestressing force steel band is widely used, and in seismic hardening occasions such as reinforced concrete post, bridge, reinforces with a large amount of use prestress steel bands.The prestressing force steel band can produce good horizontal restrain to the building cross section, with the ductility after the amplitude peak ground increase ruggedized construction.
But the key point of this technology is how to have made the connection that the prestressing force steel band two ends of the effect of tightening up can be firm, makes prestressing force steel band two ends tighten up in other words.Be positioners such as employing bolt from the prior art mostly, promptly by perforate on the prestressing force steel band in advance, thereby and connect to realize tightening up of prestressing force steel band two ends with bolt, because of factors such as operational sequence and operating spaces, the above-mentioned mode of tightening up obviously can't reach its intended purposes.
The utility model content
The utility model provides a kind of prestressing force steel band that has tightening device at the drawback of prior art.
The prestressing force steel band that has tightening device described in the utility model, described prestressing force steel band has fixed end and free end, described fixed end is connected with tightening device, described free end offers a plurality of through holes, described tightening device comprises bearing support and is arranged at bearing support interior ratchet, spanner that described spanner is provided with ratchet;
The bottom of described bearing support offers the socket that wears for free end;
Described ratchet is replaced with the ratchet that makes ratchet by ratchet and is snapped in the free-ended through hole.
In the prestressing force steel band that has a tightening device described in the utility model, can realize easily that by this tightening device the prestress steel band edge is tightened up the limit to be fixed, and has realized the good effect of tightening up.
Description of drawings
Fig. 1 is the structural representation that has the prestressing force steel band of tightening device described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the manual literal to make those skilled in the art.
As shown in Figure 1, the prestressing force steel band that has tightening device described in the utility model comprises fixed end 2 and free end 1, and described fixed end is connected with tightening device 20, and described free end offers a plurality of through holes 3.
Wherein, described tightening device 20 comprises bearing support 5, described bearing support 5 is provided with the fixture 11 that connects prestressing force steel band fixed end 2, and the socket 4 that wears for this prestressing force steel band free end 1 of the bottom that is arranged at bearing support 5, be provided with ratchet 12 and the spanner 9 that has ratchet 10 in the described bearing support 5, by shaking spanner 9, ratchet 10 can drive ratchet 12 and rotate, and make ratchet 10 and ratchet 7 replace, thereby ratchet 7 can snap in the through hole 3 of free end 1, with the fixed end 2 and free end 1 relative fixed with the prestressing force steel band.
Described ratchet 12 can be fixed by the support 6 that is arranged on the bearing support 5, is provided with axle 8 at the circle centre position of this ratchet 12, should wear support 6 by axle 8, thereby assurance ratchet 12 can rotate.One end of described spanner 9 also can be connected in axle 8, and the other end of this spanner 9 is free to rotate.
In the utility model,, make this prestressing force steel band be tightened up gradually and, fully guaranteed the tightening force of prestressing force steel band at any time by firm fixing by bearing support and ratchet, ratchet are set on this bearing support is set.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in manual and the embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
