The specific embodiment
Fig. 1 has shown that girders anchorage cable of the present utility model connects the locker overall structure, as shown in Figure 1, girders anchorage cable of the present utility model connects the anchor cable locking member that locker comprises the locking anchor cable 7 of two symmetries, and wherein said two anchor cable locking members are positioned on same the axis.
Each of two anchor cable locking members of the present utility model comprises respectively: single hole shape cylinder 3, wherein said single hole are wedged hole 5; And be used to fill in locking plate 6 in the wedged hole 5.The main body of anchor cable locking member of the present utility model is a single hole shape cylinder 3, and locking plate 6 locking during anchor cable 7 and the part anchor cable of pinning together be fixed in the wedged hole 5 of single hole shape cylinder 3.The incompatible locking anchor cable because locking plate 6 and single hole shape cylinder 3 match, and be positioned at single hole shape cylinder 3 wedged holes, therefore hereinafter the anchor cable locking member is considered as single hole shape cylinder 3, and locking plate 6 is considered as the part of single hole shape cylinder 3, just, single hole shape cylinder 3 comprises wedged hole 5 and will fill in locking plate 6 in the wedged hole 5.
Because two locking members are positioned on same the axis, therefore behind two locking member locking anchor cables 7, the active force of 7 pairs of locking devices of anchor cable accumulates on the same axis, thereby has eliminated the effect of the shearing force of prior art to locking device.
Fig. 2 has shown that with Fig. 3 girders anchorage cable of the present utility model is connected the concrete structure of locker, as shown in Figure 3, girders anchorage cable of the present utility model connects locker and also comprises having the long rectangular frame 1 that two long legs divide 11 and two short side part 12, wherein two anchor cable locking members (being single hole shape cylinder) 3 are fixed together with described two short side part 12 respectively, and lay respectively at the center of described two short side part 12.
Fig. 4 and Fig. 5 have shown the structure of locking plate 6.Locking plate 6 is a circular cone structure, so that adapt with the wedged hole 5 of locking member 3, when needs locking anchor cable, the locking plate 6 of circular cone structure inserts in the wedged hole 5 of the locking member 3 that adapts with its shape, thus the locking anchor cable.Locking plate 6 inside have cylindrical hole 6a, so that anchor cable passes, and can be around the cylindrical hole 6a by internal thread, groove or other structure 6b being set to strengthen surface roughness.
As selection, the locking plate 6 that the utility model girders anchorage cable connects locker can comprise the identical lamellar body of a plurality of sizes, shape that is used for the described frustum of a cone of splicing (or amalgamation) one-tenth, and its each lamellar body has the elongated slot that is used for locking anchor cable 7; And the cell wall of described elongated slot has internal thread, and perhaps described elongated slot has shaggy cell wall.For example locking plate 6 can comprise two semicircle frustums that structure is identical.Each semicircle frustum has an elongated slot 6a respectively, pass for anchor cable, can be around the elongated slot 6a by internal thread, groove or other structure 6b being set to strengthen surface roughness, the circular cone structure that two identical semicircle frustums of structure combine and wedged hole 5 shapes of locking member 3 adapt, when needs locking anchor cable, the locking plate 6 of the circular cone structure that is combined by two identical semicircle frustums of structure inserts in the wedged hole 5 of the locking member 3 that adapts with its shape, thus the locking anchor cable.
Describe the course of work that the utility model girders anchorage cable connects locker in detail below in conjunction with Fig. 6, Fig. 7.
Fig. 6 and Fig. 7 have shown the detailed process of the utility model locking anchor cable respectively.Shown in Fig. 6,7, the right-hand member that connects locker 3 from girders anchorage cable, the wedged hole 5 of locking member 3 will be inserted in the open inner space 13 of anchor cable 7 by long rectangular frame 1, pass the wedged hole 5 of locking member 3 again, then circular cone structure locking plate 6 is enclosed within the end that anchor cable 7 is positioned at open inner space 13, utilize the stretch-draw jack locking plate 6 to be headed in the wedged hole 5 of locking member 3, thereby anchor cable 7 is locked on the locking member or single hole cylinder 3 of right-hand member, and open space 13 right sides that make a part of anchor cable be positioned to be in long rectangular frame 1.
Then connect the end left end (not shown) repetition said process of locker 3, anchor cable 7 is locked on the locking member or single hole cylinder 3 of left end, and makes a part of anchor cable be positioned at open space 13 left sides of long rectangular frame 1 from girders anchorage cable.
So the length of the open inner space 13 of the rectangular frame 1 of will rectificating exposes anchor cable (promptly being positioned at the anchor cable on 13 left sides, inner space or right side) length and fit-up gap length sum greater than stretch-draw jack length, the other end that long rectangular frame 1 one ends link to each other; The width of the open inner space 13 of long rectangular frame 1 is greater than stretch-draw jack maximum outside diameter, so that can utilize the stretch-draw jack to head into locking plate 6 smoothly.
The utility model girders anchorage cable connects locker because two anchor cables adopt coaxial connection, produces shearing force when having avoided girders anchorage cable to connect locker locking, thereby has avoided connecting the damage of locker.
Although above the utility model is had been described in detail, the utility model is not limited thereto, and those skilled in the art of the present technique can carry out various modifications according to principle of the present utility model.Therefore, all modifications of being done according to the utility model principle all should be understood to fall into protection domain of the present utility model.
