Abstract
The invention relates to the field of suspension ropes or pull ropes for bridges, in particular to a wire rope sling reference surface ruling length fixing method. The wire rope sling reference surface ruling length fixing method comprises a step of tensioning a wire rope. The method is characterized in that: after the wire rope is tensioned, at least one standard line (2) is arranged on the outer lateral surface of the wire rope (1) along the length direction of the wire rope (1), wherein the standard line (2) is parallel to the bus of the wire rope (1). By the method, normal installation of the suspension rope can be ensured, the precision of the suspension rope can be improved, and the project quality can be ensured.
Description
Technical field
The present invention relates to be used for the suspension cable or the field, drag-line field of bridge, be specially a kind of wire rope sling datum line fixed length method.
Background technology
Wire rope sling plays a part very important in whole system as an important component part of bridge and construction work.Wire rope in use can inevitably produce the extension phenomenon, and the extension of wire rope divides elastic extension and extensibility of structure, and extensibility of structure is expendable permanent extension.In the installation process of wire rope sling, also may occur reversing simultaneously owing to the anchor head position causes.Extend and to reverse the rope that all will influence wire rope sling long, as seen the rope length of wire rope sling is affected by the external environment bigger.Improve the long precision of wire rope sling rope, controlling its error range is an important ring that guarantees the normal mounting of wire rope sling, can play crucial effects to whole engineering safety.But present wire rope sling only comprises wire rope and two ends ground tackle, lacks check and the control device long to rope, has influenced the precision and the reliability of the follow-up construction of wire rope sling.
Summary of the invention
In order to overcome the defective of prior art, provide that a kind of operation is easy, reaction in time, improve the wire rope sling auxiliary construction means of construction precision, the invention discloses a kind of wire rope sling datum line fixed length method.
The present invention reaches goal of the invention by following technical solution:
A kind of wire rope sling datum line fixed length method comprises the stretching wire rope, and be characterized in: behind the stretching wire rope, the length of steel wire rope direction is established at least one normal line in the lateral surface upper edge of wire rope, and the bus of normal line and wire rope is parallel.This normal line is unique benchmark of measuring steel wire rope length, and simultaneously, when entering subsequent handling, when wire rope was done to cut off mark, normal line can not reverse; After wire rope was made hoist cable, normal line also can not reverse when hoist cable is installed.
Described wire rope sling datum line fixed length method, be characterized in: the quantity of normal line is 2～5, and normal line is evenly distributed along the lateral surface of wire rope.
Described wire rope sling datum line fixed length method, be characterized in: the method to set up of normal line is: the lateral surface that paint, dyestuff or fluorescent material spreads upon wire rope, color can be selected redness, blueness etc. for use, to reach effect not only eye-catching but also that can obviously distinguish with the wire rope background color.
Adopt the present invention to wire rope sling enforcement line fixed length, the long variation of control cord intuitively guarantees that the long variation of rope can not take place because wire rope reverses hoist cable, plays the positioning and guiding effect simultaneously when hoist cable system anchor and on-the-spot dress rope.The invention has the beneficial effects as follows: can in time find the long bigger variation of rope, can guarantee the hoist cable normal mounting, improve the hoist cable precision, guarantee workmanship.
Description of drawings
Fig. 1 is that the present invention finishes the sectional view that wire rope behind the normal line is set;
Fig. 2 is that the present invention finishes the front view that wire rope sling behind the normal line is set;
Fig. 3 is that the present invention finishes the sectional view that wire rope behind four normal lines is set.
The specific embodiment
Below further specify the present invention by specific embodiment.
A kind of wire rope sling datum line fixed length method comprises the stretching wire rope and the line that sets up standard.During the stretching wire rope, wire rope 1 is by the tensioning equipment stretch-draw at two ends, thereby obtains metastable self length.After finishing the stretching wire rope, as depicted in figs. 1 and 2, establish a normal line 2 at the length direction of the lateral surface upper edge of wire rope 1 wire rope 1, normal line 2 is parallel with the bus of wire rope 1.The method to set up of normal line 2 is: the lateral surface that paint, dyestuff or fluorescent material spreads upon wire rope 1, color can be selected redness, blueness etc. for use, to reach effect not only eye-catching but also that can obviously distinguish with the wire rope background color.Present embodiment is selected the method for smearing with red paint for use.This normal line 2 is unique benchmark of measuring steel wire rope 1 length, and simultaneously, when entering subsequent handling, when wire rope 1 was done to cut off mark, normal line 2 can not reverse; After wire rope 1 was made hoist cable, normal line also can not reverse when hoist cable is installed.
A kind of wire rope sling datum line fixed length method comprises the stretching wire rope and the line that sets up standard.During the stretching wire rope, as shown in Figure 3, establish four normal lines 2 at the length direction of the lateral surface upper edge of wire rope 1 wire rope 1, normal line 2 is evenly distributed along the lateral surface of wire rope 1.Other steps are all same with embodiment 1.
Claims (3)
1. wire rope sling datum line fixed length method, comprise the stretching wire rope, be characterized in: behind the stretching wire rope, establish at least one normal line (2) at the length direction of the lateral surface upper edge of wire rope (1) wire rope (1), normal line (2) is parallel with the bus of wire rope (1).
2. wire rope sling datum line fixed length method as claimed in claim 1, be characterized in: the quantity of normal line (2) is 2～5, normal line (2) is evenly distributed along the lateral surface of wire rope (1).
3. wire rope sling datum as claimed in claim 1 or 2 line fixed length method, be characterized in: the method to set up of normal line (2) is: the lateral surface that paint, dyestuff or fluorescent material spreads upon wire rope (1).
