Description
Technical field
The present invention relates to the roadway support structures of a kind of truss and U-shaped steel cooperation, belong to roadway support field.
Background technique
It during pit mining, uses the tunnel majority of U-shaped steel bracket for semicircular arch or basket handle arch, encircles 2~3m of radius,
U-shaped steel holder radius in Bracing Process because geological structure or adopt movement use under the influence of, U-shaped steel bracket by tunnel week
Casing will lead to bracket in this case and collapse under pressure, tunnel becomes to its increase suddenly, the effect for the mine pressure concentrated
Shape, which is more than, causes human casualty accident.Secondly, at present many coal mines using hydraulic prop as strengthening supporting, but monomer
Hydraulic prop cooperation U-shaped steel supporting occupies that tunnel lower space is larger, influences the normal use in tunnel.In addition, mentioned above add
The method effect of strong supporting is not highly desirable, therefore is badly in need of a kind of novel strengthening supporting structure at low cost, effect is good.
Summary of the invention
In view of the above-mentioned problems, the object of the present invention is to provide a kind of structure is simple, supporting effect is good and saves
The new supporting structure of tunnel bottom space.
It to achieve the above object, is referred to as light-duty lattice in foreign countries' arch truss using the supporting construction of truss and U-shaped steel cooperation
The light-duty grillage of subrack is welded by reinforcing bar or screw-thread steel of different thickness, belongs to light-duty arch truss supporting series.In coal
There is preferable mechanical property using truss structure supporting under mine, and light weight and cost is low.
Truss structure and U-shaped steel domes are two kinds in numerous structural systems.In terms of the angle of mechanics, they can all be incited somebody to action
The moment of flexure that external load generates is converted into the axial push-pull power of component, to improve the efficiency of structure.
Arch and truss are exactly the two kinds of typical structures generated under this principle.Arch is realized with its unique curve form
Conversion of the moment of flexure to axle power, and truss then converts moment of flexure to by way of lattice the axle power of chord member.Truss and U-shaped steel arch
Structure, which combines, can be used as a kind of rationally effective structural system.So arch and truss are organically combined, just form it is a kind of by
The more reasonable new structure of power.
The technical solution adopted by the present invention is that: a kind of roadway support structure of truss and U-shaped steel cooperation, it is characterised in that it
It is made of U-shaped steel, deck, articulated joint, link bolt, chord member, web member, articulated joint and the U-shaped steel on web member top pass through deck phase
Even, the articulated joint of web member lower part is connected by deck with chord member.The deck that web member is connect with U-shaped steel and chord member is arc-shaped by section
Plate body, masking sheet, screw bolt and nut composition.U-shaped steel is stuck in the arc section slot between masking sheet and plate body, passes through bolt and spiral shell
Mother fixes masking sheet and plate body, and plate body lower part is hinged for web member and deck by two round holes.There is articulated joint at web member both ends,
Articulated joint is connected with deck by link bolt.When support force is larger, when U-shaped steel leg column can not support, using monomer liquid
Pressure pillar (12) is connected by articulated joint with the deck of bottom, and auxiliary leg column is supported.
Easy to use, easy to install, good connecting effect of the invention, occupancy lane space is small, and alternative other need not with saving
The material wanted brings many convenience for the safety of underground, production, and keeps supporting stable and effectively.

Specific embodiment
It elaborates below in conjunction with attached drawing to a specific embodiment of the invention.
As shown in Figure 1, the present invention includes U-shaped steel, deck, articulated joint, link bolt, chord member, web member composition, web member top
Articulated joint be connected with U-shaped steel by deck, the articulated joint of web member lower part is connected by deck with chord member.Carrying out supporting installation
When, first deck is fixed in U-shaped steel, then chord member is connected with deck, tunnel can be carried out by next connecting web member
Supporting.
As shown in Figures 2 and 3, the deck that web member is connect with U-shaped steel and chord member is by the arc-shaped plate body in section, masking sheet, spiral shell
Screw bolt and nut composition.U-shaped steel is stuck in the arc section slot between masking sheet and plate body, by screw bolt and nut by masking sheet and plate body
Fixed, plate body lower part is hinged for web member and deck by two round holes.
As shown in figure 4, there is articulated joint at web member both ends, articulated joint is connected with deck by link bolt.
As shown in Figure 5 and Figure 6, in top U-shaped steel stress, U-shaped steel can bear a part of power, in addition to this, another portion
Component passes to chord member through web member by articulated structure, the mechanical compliance being transmitted on chord member chord member pass to the lowermost deck,
Horizontal applied force is acted on wall by deck, and vertical is acted on U-shaped steel leg column.When deck stress is larger, if
More than the stress limit of leg column, then auxiliary shoring can be carried out by hydraulic prop.
