Abstract
The utility model relates to a reeving device used to lead a single steel strand. The device comprises a front end (1), a hollow round tube (2) and a tightening ring (4); wherein, the outer surface of the front end is spherical; the hollow round tube is integrated with the front end; and the tightening ring (4) is integrated with the end of the hollow round tube. Since the front end of the reeving device has a spherical crown structure and the outer surface of the front end is a smooth spherical surface, the resistance of the front end is little when the reeving device conducts reeving operation, and therefore construction operation is convenient. Moreover, because the inner diameter of the tightening ring of the reeving device is less than the inner diameter of the hollow round tube, the prestressed steel strand inserted into the hollow round tube can be cramped and prevented from sliding away from the reeving device in the process of reeving.
Description
Technical field
The utility model relates to a kind of device of reeving, and specifically, is a kind of reeve device of operation of single steel strand that is used to guide.
Background technology
In the existing bonded prestress work progress, the operation that steel strand need be reeved according to construction requirement, but, along with the increase of steel strand quantity, back steel strand all meets obstructions bigger when reeving operation easily, the operation that causes reeving is relatively more difficult, even the situation of the operation failure of reeving, and causes the operating efficiency in the bonded prestress work progress low.
The utility model content
Technical problem to be solved in the utility model provides a kind of device of reeving that the guiding prestress wire is reeved and operated in work progress of being convenient to.
The technical scheme in the invention for solving the above technical problem is: a kind of guiding single steel strand device of reeving comprises leading section with spherical cap structure, the hollow circular tube that is structure as a whole with the spherical crown bottom surface of leading section and the bunching ring that is structure as a whole with the hollow circular tube end.
Described hollow circular tube has at least two grooves along the hollow circular tube axial distribution.
Described groove evenly distributes along the hollow circular tube hoop.
The volume of described spherical cap structure is not less than hemispheroidal volume, and the external diameter of described hollow circular tube is less than the spherical radius of leading section.
Described bunching ring internal diameter is less than the internal diameter of hollow circular tube.
To sum up, the beneficial effects of the utility model are:
1, the leading section of the device of reeving of the present utility model is a spherical cap structure, its external surface is that smooth sphere and volume is bigger, therefore this reeves device when reeving operation, opens by squeezing that to wear the resistance that prestress wire makes leading section be subjected to less, is convenient to carry out constructing operation.
2, reeve device bunching ring internal diameter less than the internal diameter of hollow circular tube, the prestress wire that penetrates hollow circular tube is had the banding effect, prevent the prestress wire device of reeving that when reeving operation, slips away.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to shown in Figure 1, the device of reeving of the present utility model comprises leading section 1 with spherical cap structure, the hollow circular tube 2 that is structure as a whole with the spherical crown bottom surface of leading section 1 and the bunching ring 4 that is structure as a whole with hollow circular tube 2 ends; The volume of the spherical cap structure of described leading section 1 is greater than hemispheroidal volume, i.e. the hemispheroidal volume that equates with the spherical radius of this spherical cap structure greater than spherical radius of this spherical cap structure volume; Described hollow circular tube 2 external diameters equate with the radius of a circle at place, spherical crown bottom surface and are structure as a whole with the spherical crown bottom surface that the external diameter of hollow circular tube 2 is less than the spherical radius of leading section 1; Hollow circular tube 2 also has at least two along hollow circular tube 2 axial equally distributed flutings 3, and fluting described in the utility model is meant in the equally distributed strip of hollow circular tube tube wall hoop gap; Described bunching ring 4 internal diameters are less than the internal diameter of hollow circular tube 2.
Of the present utility modelly reeve device in use, at first tool using penetrates the head end of prestress wire the hollow circular tube of the device of reeving through bunching ring, the bunching ring internal diameter is less than the internal diameter of hollow circular tube, the prestress wire that penetrates hollow circular tube had the banding effect, prevent that prestress wire is at the device of reeving that slips away when operating of reeving, and because the leading section of the device of reeving is a spherical cap structure, its external surface is smooth sphere, therefore this device resistance that leading section is subjected to when reeving operation of reeving is less, is convenient to leading section guiding hollow circular tube and penetrates prestress wire in this hollow circular tube constructing operation of reeving.
Claims (5)
