Description
Technical field
The utility model belongs to the support connecting elements of side slope protective screen, is related specifically to a kind of protection network column cap supporting rope
Sliding connection structure.
Background technology
At present, the side slope protective screen used in slope protection project is mainly active network, passive net and curtain net, and steel column is made
For one of core component, vital effect is played to the energy level that bears of whole protection network or even whole system.Quilt
Dynamic formula protecting net system is made up of column, fixed system, decompression loop system and net system, belongs to grid type flexiblesystem, its
It is mainly used in intercepting falling rocks on the slope to avoid protecting object to be destroyed.When passive protection net withstands shocks, impact energy
Supporting rope system is passed to by net system, then energy is passed into ground by steel column and anchor system by supporting rope system.
Passive type protection network can be divided into 3 stages in the whole process stressing conditions to withstand shocks：Net loading process, support
Rope loading process and drawing anchor line loading process.Wherein in supporting rope loading process by consume whole impact energy 50%~
60%.Therefore, can the process supporting rope be crucial laterally smooth slide and start pressure-reducing ring with this.Supporting rope and steel at present
The connected mode of post column cap is mostly fixed/semifixed connected mode, therefore there is can not laterally be slided between supporting rope and column cap
Move or slide laterally the problem of not smooth, protecting net system can not be intercepted by design requirement to falling rocks, landslide etc.；In addition also
Supporting rope or steel wire rope directly with U-board a little contact by some, so as to which the mechanical damage of supporting rope can be caused in use,
Reduce protection network service life.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of protection network column cap supporting rope sliding connection structure, purport
Supporting rope slides laterally resistance in reduction, and lifting impact energy is improved by the smoothness of upper supporting rope lateral transport with this
The impact resistance of whole protecting net system.
In order to solve the above-mentioned technical problem, the utility model is accomplished by the following way：
Protection network column cap supporting rope sliding connection structure, including arc column head plate, steel column, upper supporting rope and drawing anchor line, institute
It is H types or I-shaped steel column to state steel column, and arc column head plate is welded on steel column upper end, the arc column head plate by a big surface plate and
The arc that both ends are tilted down forms, and is welded with four longitudinal cylinders below big surface plate, steel column is arranged on big plane
In longitudinal cylinder below plate, two relative longitudinal arcs are fixedly installed on the big surface plate in the arc column head plate
Plate, and connection is run through in the upper end of longitudinal arc by spacer pin, upper supporting rope is from by longitudinal arc, spacer pin and big plane
The closed space of plate composition passes through, and the top of steel column is additionally provided with horizontal cylinder, and drawing anchor line is two horizontal strokes being connected on steel column
To at cylinder.
Described longitudinal arc is two relative U-shaped longitudinal arcs.
Compared with prior art, the utility model has the advantage that：
This patent is not affected by about in the horizontal by spacing constraint of the upper supporting rope only by steel column column cap in the vertical
Beam, and the face that longitudinal arc is in contact with it with cap-shaped column cap plate is all arcwall face, and big surface plate is set, increase branch
The contact surface of rope is supportted, reduces the mechanical damage of supporting rope, reduces lateral resistance, makes supporting rope being capable of smooth cunning in transverse direction
It is dynamic, the decompression energy dissipation piece on supporting rope can be started rapidly when system is impacted, improve protecting net system reliability and
Bearing capacity.
Brief description of the drawings
Fig. 1 is sliding connection structure schematic diagram of the present utility model；
Fig. 2 is the schematic diagram of arc column head plate.
Each mark is respectively in figure：1st, arc column head plate, 11, longitudinal arc, 12, spacer pin, 2, steel column, 3, upper branch
Support rope, 4, draw anchor line.
Embodiment
Specific embodiment of the present utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1~2, protection network column cap supporting rope sliding connection structure, including arc column head plate 1, steel column 2, upper branch
Support rope 3 and drawing anchor line 4, the steel column is H types or I-shaped steel column, and arc column head plate is welded on steel column upper end, the arc column
The arc that head plate is tilted down by a big surface plate and both ends is formed, and four longitudinal direction circles are welded with below big surface plate
Post, steel column are arranged in longitudinal cylinder below big surface plate, are fixedly installed on the big surface plate in the arc column head plate
Two relative U-shaped longitudinal arcs 11, and the upper end of longitudinal arc by spacer pin 12 through connection, upper supporting rope from by
The closed space of longitudinal arc, spacer pin and big surface plate composition passes through, and the top of steel column is additionally provided with horizontal cylinder, draws anchor
Rope 4 is at two horizontal cylinders being connected on steel column.
Upper supporting rope is only spacing by longitudinal direction in the structure, and horizontal direction does not suffer restraints, and ensure that supporting rope
Can smoothly it be slided in horizontal direction so that impact energy can be timely transmitted when system is impacted, starts supporting rope
On decompression energy dissipation piece, improve the reliability and bearing capacity of protecting net system.Cap-shaped column cap plate is made up of steel plate bending, in
Between be big surface plate, both ends diagonally downward, turning point with arc transition to ensure whole upper surface rounding off, to reduce support
The abrasion for sliding laterally frictional resistance and upper supporting rope of rope.
Simply explain through diagrams the utility model protection network column cap supporting rope sliding connection structure and use described above
Some principles, including but not limited to homogeneous structure, application method and the scope of application.Therefore every phase for being possible to be utilized
It should change and equivalent, belong to the apllied the scope of the claims of the utility model.
