Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the strain clamp for the stay wire comprises a U-shaped pull rod 1, wherein a hanging ring 14 is integrally formed on an outer side plate at the top end of the U-shaped pull rod 1, and the hanging ring 14 is positioned on a central shaft of the U-shaped pull rod 1. Fixedly connected with is the backup pad 3 that the level was placed in U type pull rod 1, and the center of backup pad 3 is rotated and is connected with vertical screw rod 4.
As shown in fig. 1, a limiting member 2 for tensioning a steel strand is installed at the lower end of a U-shaped pull rod 1, and the limiting member 2 and a support plate 3 are parallel to each other and are arranged along the length direction of the support plate 3. Two ends of the limiting part 2 are respectively arranged on two sides of the U-shaped pull rod 1 in a sliding mode, and the lower end of the screw rod 4 penetrates through the center of the limiting part 2 and is in threaded connection with the limiting part 2. By rotating the screw 4, the stopper 2 will move up and down along the length direction of the screw 4.
As shown in fig. 1 and 2, a coaxial ratchet wheel 6 is fixedly connected to the upper end of the screw rod 4, a pawl 7 for limiting the rotation of the ratchet wheel 6 is rotatably connected to the upper side wall of the support plate 3, and the front end of the pawl 7 is inserted into the teeth of the ratchet wheel 6. When the rotation of the screw rod 4 moves the limiting member 2 to a direction approaching the supporting plate 3, the pawl 7 will not limit the rotation of the screw rod 4. When the screw rod 4 is interfered by the external environment and the limiting part 2 is to move in the direction far away from the supporting plate 3, the pawl 7 can limit the rotation of the screw rod 4, so that the steel strand is always in a tensioned state, and the limiting part 2 is prevented from loosening.
As shown in fig. 1, a coaxial handle 8 is fixedly connected to the upper end of the screw rod 4, the handle 8 is located above the ratchet 6, and the maximum diameter of the handle 8 is larger than that of the ratchet 6. The screw rod 4 positioned between the supporting plate 3 and the limiting piece 2 uniformly divides the inside of the U-shaped pull rod 1 into two relatively independent threading areas 5. Two symmetrical buffer springs 9 are fixedly connected to the limiting part 2, and the two buffer springs 9 are respectively located in the corresponding threading areas 5. The buffer spring 9 is vertically arranged and faces the direction of the support plate 3. Buffer spring 9 keeps away from one end fixedly connected with level of locating part 2 and places fixture block 10, and fixture block 10 is formed with curved holding tank 11 along length direction, and holding tank 11 is towards the backup pad 3 of top.
As shown in fig. 1, a horizontally disposed baffle 12 is fixedly connected to one end of the screw rod 4 away from the handle 8, the baffle 12 is located outside the limiting member 2, and the maximum diameter of the baffle 12 is greater than the maximum diameter of the screw rod 4. A rubber pad 13 facing the stopper 2 is fixedly bonded to the upper surface of the baffle 12. The lower end of the screw rod 4 exceeds the lower side wall of the U-shaped pull rod 1, and when the lower side wall of the limiting part 2 is in contact with the baffle 12, the two ends of the limiting part 2 can slide out of the U-shaped pull rod 1.
The specific effects of the embodiment are as follows:
when the steel strand is pulled and fastened, the hanging ring 14 on the U-shaped pull rod 1 is fixed with the ground, the steel strand penetrates through the threading area 5 formed in the U-shaped pull rod 1, and then the steel strand penetrates through the clamping block 10 and is fixed on the limiting part 2. Because the utility model discloses be formed with two independent threading districts 5 to can satisfy two steel strand wires's fixed taut simultaneously, not only save the material but also improve the utilization ratio. Because the two ends of the limiting piece 2 are arranged on the U-shaped pull rod 1 in a sliding manner, the limiting piece 2 moves up or down along the length direction of the screw rod 4 when the screw rod 4 is rotated, and the two ends of the limiting piece 2 keep synchronous motion when moving, thereby effectively avoiding the deviation of the limiting piece 2. Thereby enable steel strand wires remain stable taut, the torsional condition can not appear, compare in the mode that the two nuts of tradition adopted were adjusted, the utility model discloses when straining steel strand wires, only need to realize the taut work to steel strand wires through rotating screw rod 4, installation convenient more, swift has shortened installation time, has improved the efficiency of installation.
The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, any modification, equivalent replacement, or improvement made within the design concept of the present invention should be included within the protection scope of the present invention.
