It has, and protection network support stability is better, the better characteristics of energy dissipation effect.
Description
Technical field
The utility model relates to side slope protective screen system, the flexible passive protection net of particularly a kind of easy reparation.
Background technology
Chinese patent literature discloses one and " easily repaiies composite flexible passive protection net " (CN201420503041.8), it is made up of multispan protective screening, across protecting screen structure be often: supporting rope is fixed on steel column top and bottom 4 and unloads and buckle, wire lath is connected on steel column through shackle, steel column is hinged on the bearing pin of U-board on anchor plate, draw anchor line to be fixed on steel column top board, the other end connects energy dissipator one end through shackle, and the energy dissipator other end connects anchor pole through shackle.Energy dissipator is made up of more than one intersection annulus, and its two outer end is steel wire rope end head.It has good flexible protective function to impact load, but there is following defect, one, energy dissipator only one end adopts shackle to connect, the inconvenient dismounting and change of energy dissipator, and the energy dissipator on supporting rope is arranged on across beyond end (namely first is extremely last across protective screening across protective screening), therefore, can not play better energy dissipating effect.Its two, in view of steel column is hinged on steel column base, and supporting rope can not form well directed firm effect to protective screening.Supporting rope is only one, and supporting rope is hung on the top of multispan protective screening, the right and below, and the two ends of this supporting rope are anchored at the same left side of multispan protective screening again.They are three years old, the anchor line that draws that steel column top adopts two to separate at an angle is fixed, namely often anchor line is drawn to be fixed on four anchor points across two steel columns of steel protecting wire net through four, which increase difficulty of construction, the active force that four anchor points of single span protective screening produce comparatively is hard to keep in one direction.
Utility model content
The purpose of this utility model is to provide the flexible passive protection net that a kind of protective screening stability of strutting system is better, energy dissipating effect is better.
The purpose of this utility model is achieved in that a kind of follow-on flexible passive protection net, is made up of multispan protective screening, to be often fixed between two steel columns by wire lath across protective screening and to form; The top board at this steel column top is fixed with shackle on, steel column bottom-hinged, on steel column base, steel column base is fixed with shackle; Upper supporting rope be hung in turn from left to right multiple steel column tops of described multispan protective screening on unload and buckle, the two ends anchoring of upper supporting rope on the ground, and upper supporting rope is fixed with two energy dissipators through shackle, these two energy dissipators lay respectively at first across protective screening initiating terminal with last is across between protective screening end; Lower support rope unloads under being hung on multiple steel column bases of described multispan protective screening from left to right in turn and buckles, the two ends anchoring of lower support rope on the ground, and lower support rope is fixed with two other energy dissipator through shackle, this two other energy dissipator lays respectively at first across protective screening initiating terminal with last is across between protective screening end.
In described two energy dissipators and two other energy dissipator, the left and right two ends of each energy dissipator all connect through shackle.
Describedly often draw anchor line across the top board of two steel columns of protective screening is also fixed with one respectively, and these two are drawn the length of anchor line identical, these two are drawn the outer end of anchor line to be fixed together.
The utility model, on " easily repairing composite flexible passive protection net " (CN201420503041.8) basis, improves further mainly for shortcomings such as its protective screening discontinuity equalization, energy dissipator do not play a role completely and forms.
Compared with prior art, the utility model has following characteristics and advantage:
1, adopt upper and lower two supporting ropes and often go up stay cord across two steel columns of protective screening being arranged respectively one, and two upper stay cords are intersected in a bit form upper pulling force as 45 degree at an angle, like this, protective screening is subject to the pulling force in multiple directions and can be stabilized in either direction, to tackle the falling rocks in any direction.
2, the position that upper and lower supporting rope is positioned within the left and right two ends of protective screening arranges an energy dissipator respectively, and energy dissipator two ends all adopt shackle to connect, be convenient to maintenance and change, simultaneously, in upper and lower supporting rope, an energy dissipator is positioned at first across protective screening initiating terminal, and another energy dissipator is positioned at last across protective screening end, so more be conducive to forming buffering to burst external force, play better energy dissipating effect.

Fig. 1 is the front view of existing soft protecting net.
Fig. 2 is main TV structure figure of the present utility model.
Fig. 2 a, Fig. 2 b are the structural representation of the top of steel column shown in Fig. 2 and steel column base respectively.
Detailed description of the invention
In Fig. 1,1, wire lath; 2, steel column; 3, steel column base; 4, supporting rope; 5, anchor line is drawn; 6, anchor pole; 7, energy dissipator.Fig. 2 illustrates follow-on flexible passive protection net, is made up of multispan protective screening, to be often fixed between two steel columns 2 by wire lath 1 across protective screening and to form; The top board 2a at this steel column 2 top is fixed with shackle 2b on, steel column 2 bottom-hinged, on steel column base, steel column base is fixed with shackle 2c; Upper supporting rope 41 is hung on the upper shackle 2b at multiple steel columns 2 top of described multispan protective screening from left to right in turn, the two ends anchoring of upper supporting rope 41 on the ground, and upper supporting rope 41 is fixed with two energy dissipators 31 through shackle, these two energy dissipators 3 lay respectively at first across protective screening initiating terminal with last is across between protective screening end; Lower support rope 42 is hung on the lower shackle 2c of multiple steel column bases of described multispan protective screening from left to right in turn, the two ends anchoring of lower support rope 42 on the ground, and lower support rope 42 is fixed with two other energy dissipator 32 through shackle, this two other energy dissipator 32 lays respectively at first across protective screening initiating terminal with last is across between protective screening end.See Fig. 2 a, upper supporting rope 41 to be hung on steel column top board in shackle 2b, draws anchor line one end to be fixed on steel column top board; See Fig. 2 b, steel column understructure is: U-shaped plate 2e is welded on as being anchored on the anchor plate 2d on ground, bearing pin 2f is erected on two cant boards of U-board rotationally, be fixed on bearing pin 2f bottom steel column 2, the base plate bottom surface of U-board is welded with a level board 2g, lower shackle 2c is fixed on level board 2g, is fixed on bearing pin 2f bottom steel column 2.In two energy dissipators 31 and two other energy dissipator 32, the left and right two ends of each energy dissipator all connect through shackle.So that the dismounting of energy dissipator and replacing.Often draw anchor line 5 across the top board 2a of two steel columns 2 of protective screening is also fixed with one respectively, and these two are drawn the length of anchor line identical, these two draw the outer end of anchor line to be fixed together after anchoring on basement rock again.
