Description
Technical field
The utility model belongs to side slope protective screen supporting member, specifically falling rocks is played to the protective screening base component of buffering interception function.
Background technology
At present, for high-risk falling rocks region many uses passive protection net in domestic side slope protection engineering, wherein, for existing system, passive net pedestal, except playing support function, in the process that rock-fall impact occurs, also serves the transitional function of the optimum deformation of total system.In existing pedestal type, steel column is rigidly fixed on base plate and forms pedestal, and the base plate of pedestal is anchored on ground, and protective screening is fixed on pedestal, do not have flexible protective ability to precipitate external force, the impact load of Falling Rocks causes structural destruction to protective screening local.Secondly, existing pedestal can not position the position of supporting rope (wire rope) and retrain, and fixing of inconvenient supporting rope, meanwhile, supporting rope in use easily causes mechanical damage.If this technical problem can not effectively solve, the safety of system and service efficiency are difficult to be protected.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of protective screening U-shaped steel column pedestal falling rocks to pooling feature and convenient constraint positioning supports rope.
The purpose of this utility model is achieved in that the U-shaped steel column pedestal of a kind of protective screening, comprise steel column and base plate, described base plate is rectangle steel plate, four angles place of rectangle steel plate respectively has an anchor hole, upper U-shaped plate is identical with the shape of lower U-shaped plate, and the two opening direction is welded on base plate on the contrary, be erected on two pin-and-holes of upper U-shaped plate and lower U-shaped plate rotationally as the wire rope fixed pin shaft blocking wire rope, rectangle riser is welded on left side or the right side place of the lower U-shaped plate on base plate, steel column fixed pin shaft is erected on two holes of lower U-shaped plate and rectangle riser rotationally, be fixed on steel column fixed pin shaft bottom described steel column, rectangular ribs is welded between rectangle riser and lower U-shaped plate, and is welded on base plate.
Described wire rope fixed pin shaft adopts seamless steel pipe to make, and steel column fixed pin shaft adopts round steel to make.
The stress point of described steel column on steel column fixed pin shaft and the stress point of wire rope on wire rope fixed pin shaft are all positioned on a rectangular diagonal of base plate.
Compared with existing base construction, the beneficial effect of this utility model is:
1, in existing pedestal, steel column (section steel manufacture) and base plate be rigidly connected (namely welding together) form pedestal, in this pedestal steel column be to be hinged on pedestal (or, bearing pin is fixed on the upper and lower U-shaped plate of pedestal, be arranged on rotationally on bearing pin bottom steel column), like this, under protective screening is subject to Rolling Stone impact load situation, be fixed on protective screening on steel column and the hinged steel column of base plate (being anchored on the ground) to produce trackability and offset, and play flexible buffer effect, reduce the rigid destruction of impact load to protective screening.
2, the supporting rope installing protective screening is stuck in below the wire rope fixed pin shaft between upper and lower U-shaped plate, solve constraint and the orientation problem of supporting rope, meanwhile, supporting rope stressed mobile time contact with the wire rope fixed pin shaft of rotation, and scratch class mechanical damage can not be formed.
U-shaped steel column pedestal can provide a more mild transition condition, more firm braced structures (upper and lower U-shaped plate and riser, reinforcing rib etc.), stress in minimizing system deformation process on wire rope is concentrated, thus improve the protective capacities of system, reduce workload and the maintenance cost of system maintenance simultaneously.

Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Fig. 1-4 illustrates, base plate 1 is rectangle steel plate, four angles place of rectangle steel plate respectively has an anchor hole, upper U-shaped plate 2 is identical with the shape of lower U-shaped plate 3, and the two opening direction is welded on base plate 1 on the contrary, lock as the wire rope fixed pin shaft 6(wire rope steady pin 8 blocking wire rope 10) be erected on two pin-and-holes of upper U-shaped plate and lower U-shaped plate rotationally, rectangle riser 5 is welded on left side or the right side place of the lower U-shaped plate 3 on base plate 1, steel column fixed pin shaft 7 is erected on two holes of lower U-shaped plate and rectangle riser rotationally, be fixed on steel column fixed pin shaft 7 bottom steel column 9, rectangular ribs 4 is welded between rectangle riser and lower U-shaped plate, and is welded on base plate 1.Wire rope fixed pin shaft 6 adopts seamless steel pipe to make, and steel column fixed pin shaft 7 adopts round steel to make.The stress point of steel column 9 on steel column fixed pin shaft 7 and the stress point of wire rope 10 on wire rope fixed pin shaft 6 are all positioned on a rectangular diagonal of base plate 1.Its intensity is higher, is applicable to high level protective screening.
Embodiment:
Base plate is rectangle, and corner goes out respectively to open an anchor hole; Upper U-shaped plate is struck out asymmetric U-shaped by rectangle steel plate, 45 °, long end non-solder face chamfering, stamping surface expense hole; Lower U-shaped plate is struck out symmetrical U-shaped by rectangle steel plate, the U-shaped end rounding in non-solder face, stamping surface expense hole; Riser is rectangle steel plate, and 45 °, one end, non-solder face chamfering, by chamfered end expense hole; Reinforcing rib is rectangle steel bar; Steel column fixed pin shaft adopts round steel to make, first pin (Fig. 1) should be extracted in installation process, steel column is inserted into upper U-shaped plate and riser centre position, steel column pin-and-hole and upper U-shaped plate, riser pin-and-hole is made to be on same axis, again pin is passed institute porose, steel column and pedestal are linked as a whole; Wire rope fixed pin shaft adopts seamless steel pipe to make, and during installation, supporting rope can directly pass below pin.
