Description
Technical field
The present invention relates to protection network, particularly to a kind of passive protection net column stigma connecting structure.
Background technology
Side slope passive protection net is the fence type flexiblesystem based on steel wire rope, and this system is by steel wire rope
Net or ring network (additional layer steel wire grid when intercepting fritter falling rocks), fixed system (anchor pole, draw
Anchor line, pedestal and supporting rope), pressure-reducing ring and four major parts of steel column composition.This system typically sets
It is placed in certain position on slope, for intercepting falling rocks on slope to avoid it to destroy protection object, because of
This most also becomes stone blocking net.
Existing passive protection net pillar construction, when Impact Load, is passed energy by protection network
Passing supporting rope, wire saws effect supported, column will produce the horizontal beat of certain amplitude with the most inclined
Pendulum, is drawn anchor line after column produces beat and then by power special delivery.For propping up that horizontal beat uses at present
Support rope mostly is fixing and is connected or is slidably connected, under temporary impact load action with the type of attachment of stigma
Crossing senior general due to frictional resistance causes energy transmission smooth, so cause column produce transversely deforming excessive,
Structural instability destruction etc. are destroyed.
Summary of the invention
The technical problem to be solved is to provide a kind of passive protection net column stigma and connects structure
Make, to be effectively improved column mechanical property, improve the suitable of the transmission of energy under its temporary impact load action
Smooth property, and simplify the structure of column, facilitate site operation and installation.
The technical solution adopted for the present invention to solve the technical problems is:
The passive protection net column stigma connecting structure of the present invention, including column, upper supporting rope with draw anchor
Rope, is characterized in that: the upper end of described column is provided with cylinder by bearing pin, U-shaped ring opening and this
Cylinder is fixing to be connected；Described draw anchor line to pass this U-shaped ring to be connected with clasp, clasp connects band sliding
Wheel clasp, pulley is arranged on band pulley clasp；Described upper supporting rope passes band pulley clasp, stress
After act on pulley.
The invention has the beneficial effects as follows, upper supporting rope is with to draw anchor line to pass through clasp, band pulley clasp direct
Being connected, shorten the path of impact load transmission of knowing clearly, the transmission making impact load is more smoothly；Vertical
Post only undertakes vertical pressure, has given full play to the feature that column axial compression mechanical property is good, and no longer
Supporting rope and draw the impact load between anchor line to transmit in participation, can be greatly reduced column the most partially
Pendulum, it is to avoid the possibility that column generation transverse curvature is destroyed, thus improve the work of whole passive protection net
Make usefulness；Simplify the structure of column, facilitate site operation and installation.
Accompanying drawing explanation
This specification includes such as next width accompanying drawing:
Fig. 1 is the schematic perspective view of passive protection net column stigma connecting structure of the present invention.
Component name shown in figure and corresponding labelling: column 10, cylinder 21, rear side cylinder 22,
U-shaped ring 23, clasp 24, band pulley clasp 25, pulley 26, upper supporting rope 31, draws anchor line 32.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
With reference to Fig. 1, the passive protection net column stigma connecting structure of the present invention, including column 10, on
Supporting rope 31 and draw anchor line 32.The upper end of described column 10 is provided with cylinder 21, U by bearing pin
Type ring 23 opening is fixing with on this cylinder 21 to be connected.Described draw anchor line 32 through this U-shaped ring 23
Being connected with clasp 24, clasp 24 connects band pulley clasp 25, pulley 26 is arranged on band pulley and buckles
On ring 25.Described upper supporting rope 31, through band pulley clasp 25, acts on after stress on pulley 26.
With reference to Fig. 1, upper supporting rope 31 is with to draw anchor line 32 straight by clasp 24, band pulley clasp 25
Connecing and be connected, decrease the path of impact load transmission, the transmission making impact load is more smoothly.Rolling
Cylinder 21 be provided with the vertical pressure that impact load is beneficially converted to act on column 10, column
10 undertake vertical pressure, and are no longer participate in supporting rope 31 and draw the impact lotus between anchor line 32
Carry transmission, the horizontal beat of column 10 can be greatly reduced, thus improve the work of whole passive protection net
Make usefulness.The stigma structure of column 10 is able to structure, facilitates site operation and installation.
With reference to Fig. 1, column more than 10 employing cross section is the shaped steel of I shape, and cylinder 21 is installed on vertical
Post 10 is in the front groove of upper supporting rope 31 side.In order to make to draw anchor line 32 to have stress preferably to pass
Give column 10 and be converted to vertical pressure, as one preferred embodiment, described column 10
Upper end by bearing pin be provided with rear side cylinder 22, on rear side of this, cylinder 22 is positioned at column 10 away from upper
In the pit of supporting rope 31 side, rear side cylinder 22, cylinder 21 axis parallel.
The above one passive protection net column stigma connecting structure of the present invention that simply explains through diagrams
Some principles, be not intended to be confined to the present invention shown in and described concrete structure and the scope of application
In, therefore every corresponding amendment being likely utilized and equivalent, belong to the present invention and applied for
The scope of the claims.
