Description
Technical field
The utility model is related to a kind of roadway support devices, belong to Roadway Support Technology field.
Background technology
Metallic support support technology mainly divides rigid support supporting and collapsible timbering supporting, wherein rigid support to allow to press
Contracting quantitative change shape is small, and working resistance increases with deflection and reduced, until destroying and resistance of losing the job；Collapsible timbering allows to press
Compression deformation amount is big, and in structure design compression zone, working resistance is with decrement increase or constant-resistance greatly.Metallic support branch
Shield regards holder as prop, and country rock is load, and destruction is since bending moment reaches the bursting stress of yield limit on holder
It is caused, simultaneously as holder bear lateral pressure and load it is uneven often make holder loss of stability or contractibility and weaken or
Lose vertical bearing capacity.
During pit mining, use the tunnel majority of metallic support for trapezoidal or arch, holder is in Bracing Process
Because geological structure or adopt action use under the influence of, metallic support by rock stratum around tunnel to its suddenly increase, concentrate
The effect of mine pressure can cause holder to collapse under pressure in this case, and tunnel, which deforms, more than causes human casualty accident.Its
Secondary, current many coal mines are used as strengthening supporting, but hydraulic prop complexed metal bracket support using hydraulic prop
It occupies that tunnel lower space is larger, influences the normal use in tunnel.In addition, the method effect of strengthening supporting mentioned above is not
It is highly desirable, therefore it is badly in need of a kind of novel strengthening supporting structure at low cost, effect is good.
Invention content
The purpose of this utility model is that：A kind of roadway support structure of truss and metallic support cooperation is provided, to solve
Existing excavation support structure, easily leads to holder and collapses under pressure, and tunnel deforms and more than causes human casualty accident, and supporting effect is not
Ideal and supporting construction take up space greatly, the problems such as influencing tunnel normal use.
To solve the above problems, the quasi- roadway support structure using such a truss and metallic support cooperation, including even
The metallic support of beam and multiple trapezoidal settings is connect, each metallic support includes there are one rack beam and being respectively arranged at holder
Two oblique pillars at crossbeam both ends, support beam is set to the downside of rack beam, and the both ends of support beam are fixed respectively
In on two oblique pillars, two tie-beams are arranged perpendicular to metallic support, and the support corresponding to the multiple metallic support
The both ends of crossbeam are respectively hinged with two tie-beams, and the lower end of two auxiliary support plates is hingedly connected in support beam
Portion, the upper end of two auxiliary support plates are hingedly connected to the downside at rack beam both ends, the upper and lower ends difference of vertical supporting plate
It is articulated with the middle part of rack beam and support beam.
In aforementioned supporting construction, the corresponding support of described two tie-beams is provided with hydraulic prop, and tie-beam with
The upper end of hydraulic prop is hinged；
In aforementioned supporting construction, support beam is parallel with rack beam；
In aforementioned supporting construction, between support beam and tie-beam, auxiliary support plate and support beam and rack beam it
Between and vertical supporting plate and support beam and rack beam between be hinged by articulated joint；
In aforementioned supporting construction, the support beam, tie-beam, auxiliary support plate and vertical supporting plate are T-steel plate
Structure.
Compared with prior art, the utility model can improve the supporting stability in tunnel, enhance the safety of supporting, this
Utility model enhances the reliability of supporting plate by using triangular structure, prevent coal seam or rock stratum to suspension device not
Uniform force causes supporting unexpected situation occur, meanwhile, the utility model is easy to use, easy to install, good connecting effect, occupies lane
Road space is small, brings many convenience for the safety of underground, production, and keeps supporting more stable and effective.
