Specifically, cord clip 1 includes two fixture blocks 11 with fore shaft.Two pieces of fixture blocks 11 are involutory and are fixedly connected.Two pieces of folders
Block 11 is detachably connected by locking member, and upon connection, and the fore shaft of two pieces of fixture blocks 11 is opposite to surround to be formed for prestressing force drawing
The lockhole 110 that cord clip is held.
As a kind of preferable embodiment, in order to reduce the frictional resistance between cord clip and card slot inner wall to reduce pre- answer
The loss of prestress of power drag-line, fixture block 11 are hemispherical.
In the present embodiment, fixture block is high strength alloy steel hemisphere, and fore shaft is arranged in the middle part at the position that fixture block is involutory.It is high
The radius of strength alloys steel hemisphere and the size of fore shaft, can be arranged according to design requirement, and two fixture blocks 11 are (high by 4 locking members 12
Strength bolt) it is fixed.The fixation of two fixture blocks 11 can be spliced into a spherical cord clip after tightening by high-strength bolt.Prestressed cable
The diameter of diameter and lockhole matches.
In the present embodiment, in order to further lower frictional force, the inner wall of broadening section 22 has the arc with the outer wall of cord clip 1
Spend compatible arcwall face.It is rounded to widen section 22.
In the present embodiment, it widens on the inner wall of section coated with lubricant layer.Further, lubricant layer is the lubrication of coating
Oil.
In the present embodiment, limiter is made of high strength alloy steel.
The socket joint slot 23 plugged for strut is formed on the outer wall of limiter 2.The end of prestressing force beam string structure strut plugs
It in socket joint slot, then welds firm, weld seam detection work is carried out after the completion of welding, preservative treatment is done in the outside of limiter 2.
In some embodiments, the quantity of socket joint slot 23 is two, two angled settings of socket joint slot 23.
Limiter is made to be seated firmly on " triangle " that two form between strut and beam string by two struts
Corner position.
The present invention provides a kind of prestressed cable installation method of company's Cable Structure for prestressing force beam string structure strut, including
Following steps:
S1: providing limiter 2, and the surface of the limiter 2 is equipped with both ends perforation, the limiter 2 is installed on pre-
On the strut of stress beam string.
In the present embodiment, socket joint slot 23 is formed on the outer wall of limiter 2.The quantity of socket joint slot 23 is two.Pacifying
Fill limiter when, the end of prestressing force beam string structure strut is inserted in socket joint slot, then weld it is firm, welding after the completion of welded
Seam detection work, preservative treatment is done in the outside of limiter 2.
As a kind of preferable embodiment, in one of lubricating oil of inner wall brush of the broadening section of limiter.
In the present embodiment, the quantity of limiter is multiple.
S2: cord clip 1 is provided, cord clip 1 is held on the junction that prestressed cable 3 is connect with strut.
According to the installation site of limiter 2, in identifying junction corresponding with installation site on prestressed cable 3.
Cord clip 1 has a lockhole 110, the prestressed cable 3 is arranged in the lockhole 110, so that the cord clip 1
It is attached to the junction.In the present embodiment, the quantity of junction is many places.Correspondingly, the quantity and limiter of cord clip
Quantity is identical.
Specifically, cord clip 1 includes two fixture blocks 11.Two pieces of fixture blocks 11 are involutory and are fixedly connected by locking member.Fixture block
The fore shaft of perforation is offered on 11, the fore shaft of two pieces of fixture blocks 11 is combined to form lockhole 110.Two pieces of fixture blocks are installed on prestressing force to draw
Two pieces of fixture blocks 11 are involutory and are fixedly connected using locking member, so that cord clip is attached to pre- answer by the junction of rope identified
On power drag-line.
S3: the cord clip 1 for being held on junction is placed in card slot, so that the both ends of cord clip are corresponded in the two of card slot
End.
Card slot includes two necking segments 21 and the broadening section 22 that is connected between two necking segments 21.The width of necking segment 21 is less than
The width of cord clip.The width of necking segment 21 is greater than the diameter of prestressed cable.
Lifting is clamped with the prestressed cable 3 of cord clip 1, and the cord clip for being held on prestressed cable is placed in broadening section 22
In, cord clip is arranged along the length direction of broadening section, so that the both ends of cord clip are corresponded in the necking segment 21 at broadening 22 both ends of section.
S4: the prestressed cable at the both ends of holding position is placed in correspondingly in the both ends of card slot.
The prestressed cable at the both ends of holding position is placed in correspondingly in the necking segment 21 at broadening 22 both ends of section.Rope
The activity space moved along the length direction of broadening section is formed between folder 1 and the inner wall for widening section 22.
Construction personnel reaches the installation site of limiter by high altitude vehicle, lifts by crane prestressed cable by lifting machine, and
It is hung to below strut, then corresponding cord clip is placed in the broadening section of limiter.Due to the cord clip on prestressed cable at this time
It is not completely fixed in the card slot of limiter, so whole cord clips on prestressed cable are put into before broadening section,
Cord clip is temporarily fixed at limit together with prestressed cable using wirerope improving bud grafting by the cord clip for having been placed in broadening section together
On the device of position.
S5: after cord clip is placed in the both ends that card slot and prestressed cable are placed in card slot, prestressed cable is applied
Prestressing force.
When all cord clips are all put into the broadening Duan Zhonghou of limiter, the slightly prestressing force on prestressed cable makes pre-
Stress drag-line reaches tight state, takes high altitude vehicle by construction personnel and all takes the wirerope of interim cord clip.Later, to pre-
The classification of stress drag-line applies prestressing force until reaching design prestress value.
At this point, there are certain pressure between cord clip and limiter, and pressure is applied to strut.
It should be noted that this specification structure depicted in this specification institute accompanying drawings, ratio, size etc., only to cooperate
The bright revealed content of book is not intended to limit the invention enforceable limit so that those skilled in the art understands and reads
Fixed condition, therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, not
