Abstract
It the utility model is related to a kind of flexible hangar tunnel with lateral inclination support bar, including steel arch-shelf, transverse horizontal support bar, lateral inclination support bar, supporting rope, depressurized system and flexible metal mesh sheet, lateral inclination support bar is connected to form triangle rock-steady structure with adjacent steel arch-shelf, transverse horizontal support bar；Supporting rope and two steel arch-shelfs of end connect, and depressurized system is between supporting rope and the steel arch-shelf of end；Flexible metal mesh sheet is layered on above supporting rope, is connected in a manner of sling or suture rope.In the utility model, the triangular structure being made up of adjacent steel arch-shelf, transverse horizontal support bar, lateral inclination support bar, overcome the stability deficiency of original rectangle being made up of adjacent steel arch-shelf, transverse horizontal support bar, the shortcomings that low intensity, especially when bearing vertical impact, whole steel construction is not likely to produce deformation, increases substantially whole flexible hangar tunnel protective capacities.
Description
Technical field
The utility model belongs to flexible hangar tunnel technical field, and in particular to a kind of flexible canopy with lateral inclination support bar
Hole.
Background technology
Flexible hangar tunnel is made up of steel structure supporting system, supporting rope system, depressurized system and flexible metal mesh sheet, often
Alleviate the shock loading of falling rocks for positions such as Mountain Tunnels mouths, avoid its direct surge protection object.Its principle is to pass through
The impact energy of falling object is passed to supporting rope system, then passes to steel knot by supporting rope system by top, the net system of side
Structure support system.For steel structure supporting system, at present frequently with continuous steel arch-shelf, supported between adjacent bow member with horizontal cross
Bar is attached.Because what is formed between two adjacent groups bow member and transverse horizontal support bar is rectangle unstable structure, therefore
Overall deformation easily occurs for steel construction when bearing vertical impact energy, causes to damage.
Utility model content
The utility model provides a kind of flexible hangar tunnel with lateral inclination support bar, to overcome existing flexible hangar tunnel steel construction
The shortcomings that vertical direction stability deficiency.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of flexible hangar tunnel with lateral inclination support bar, including the support of steel arch-shelf, transverse horizontal support bar, lateral inclination
Bar, supporting rope, depressurized system and flexible metal mesh sheet, lateral inclination support bar and adjacent steel arch-shelf, transverse horizontal support bar
Connection forms triangle rock-steady structure；Supporting rope and two steel arch-shelfs of end connect, and depressurized system is located at supporting rope and end
Between steel arch-shelf；Flexible metal mesh sheet is layered on above supporting rope, is connected in a manner of sling or suture rope.
Further, lateral inclination support bar head and the tail are respectively with two adjacent steel arch-shelfs to bolt or other connected modes
Connection, makes it form triangle rock-steady structure between transverse horizontal support bar, steel arch-shelf.
The beneficial effect of the utility model is：In the utility model, by adjacent steel arch-shelf, transverse horizontal support bar, horizontal stroke
The triangular structure formed to inclined shore bar, overcomes original square being made up of adjacent steel arch-shelf, transverse horizontal support bar
The stability deficiency of shape, the shortcomings that low intensity, especially when bearing vertical impact) whole steel construction is not likely to produce deformation, makes whole
Individual flexible hangar tunnel protective capacities increases substantially.
Brief description of the drawings
Fig. 1 is general illustration of the utility model with lateral inclination support bar flexible hangar tunnel.
Fig. 2 is steel construction schematic diagram of the utility model with lateral inclination support bar flexible hangar tunnel.
Connected mode schematic diagrams of the Fig. 3 between lateral inclination support bar and transverse horizontal support bar, steel arch-shelf.
Embodiment
Specific embodiment of the present utility model is described below in conjunction with the accompanying drawings, it is new to be better understood from this practicality
Type.
The flexible hangar tunnel with lateral inclination support bar as shown in Figure 1, including steel arch-shelf 10, transverse horizontal support bar 20,
Lateral inclination support bar 30, supporting rope 40, depressurized system 50 and flexible metal mesh sheet 60, lateral inclination support bar 30 with it is adjacent
Steel arch-shelf 10, the connection of transverse horizontal support bar 20 form triangle rock-steady structure；Supporting rope 40 is connected with two steel arch-shelfs of end,
Depressurized system 50 is between supporting rope 40 and the steel arch-shelf of end；Flexible metal mesh sheet 60 is layered on above supporting rope 40, with rope
Button or suture rope mode are connected.
As shown in Figure 2 and Figure 3, the head and the tail of lateral inclination support bar 30 respectively with two adjacent steel arch-shelfs 10 with bolt (or its
Its connected mode) connection, it is formed triangle rock-steady structure between transverse horizontal support bar 20, steel arch-shelf 10.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these are improved and profit
Decorations are also considered as the scope of protection of the utility model.
