Abstract
The present invention provides a kind of novel metal stent for roadway support, including rack beam and two oblique pillars for being respectively arranged at rack beam both ends, gate beam is arranged at the downside of rack beam, and the both ends of gate beam are respectively articulated with and are arranged on two oblique pillars, the lower end of two auxiliary support plates is articulated with the middle part of gate beam, the upper end of two auxiliary support plates is hingedly connected to the downside at rack beam both ends, and the upper and lower ends of vertical supporting plate are hingedly connected to the middle part of rack beam and gate beam.To solve existing excavation support structure, easily lead to stent and collapse under pressure, the problems such as tunnel deforms and more than causes human casualty accident, and supporting effect is undesirable, and supporting construction takes up space greatly, influences tunnel normal use.The invention belongs to roadway support field.
Description
Technical field
The present invention relates to a kind of roadway support device, belongs to Roadway Support Technology field.
Background technology
Metallic support support technology mainly divides rigid support supporting and collapsible timbering supporting, and wherein rigid support allows to press
Contracting quantitative change shape is small, and working resistance increases and reduces with deflection, 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 big with decrement and increases, or constant-resistance.Metallic support branch
Shield regards stent as prop, and country rock is load, its destruction is due to the bursting stress that bending moment reaches yield limit on stent
It is caused, simultaneously as stent bear lateral pressure and load it is uneven often make stent loss of stability or contractibility and weaken or
Lose vertical bearing capacity.
During pit mining, using the tunnel majority of metallic support, stent is in Bracing Process for trapezoidal or arch
Because in geological structure or adopting under the influence of action uses, metallic support is subject to rock stratum around tunnel to increase it suddenly, concentrates
The effect of mine pressure, can cause stent to collapse under pressure in this case, and tunnel, which deforms, more than causes human casualty accident.Its
Secondary, current many Coal Exploitations are used as strengthening supporting, but hydraulic prop complexed metal bracket support with hydraulic prop
Occupy that tunnel lower space is larger, influence 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 the new strengthening supporting structure that a kind of cost is low, effect is good.
The content of the invention
It is an object of the invention to：A kind of novel metal stent for roadway support is provided, to solve existing tunnel branch
Frame structure, easily leads to stent and collapses under pressure, and tunnel deforms and more than causes human casualty accident, and supporting effect is undesirable, and
Supporting construction takes up space greatly, the problems such as influencing tunnel normal use.
To solve the above problems, intend using such a novel metal stent for roadway support, including rack beam
With two oblique pillars for being respectively arranged at rack beam both ends, gate beam is arranged at the downside of rack beam, and aids in horizontal
The both ends of beam, which are respectively articulated with, to be arranged on two oblique pillars, and the lower end of two auxiliary support plates is articulated with gate 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 gate beam.
In aforementioned metal stent, gate beam is parallel with rack beam.
In aforementioned metal stent, between the both ends of gate beam and oblique pillar, auxiliary support plate and gate beam and branch
Between frame crossbeam, and it is hinged between vertical supporting plate and gate beam and rack beam by articulated joint.
In aforementioned metal stent, the articulated joint is universal hinge.
In aforementioned metal stent, the gate beam, auxiliary support plate and vertical supporting plate are T-steel harden structure.
Compared with prior art, the present invention can improve the supporting stability in tunnel, strengthen the security of supporting, the present invention
Strengthen the reliability of metallic support supporting plate by using triangular structure, prevent coal seam or rock stratum to suspension device not
Uniform force causes supporting unexpected situation occur, meanwhile, easy to use, easy to install, good connecting effect of the invention, it is empty to take tunnel
Between it is small, safety, production for underground bring many convenience, and make supporting more stables and effective.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
The detailed description of step, it will be appreciated that specific embodiment described herein only to explain the present invention, is not used to limit this hair
It is bright.
Embodiment：
It is a kind of to be used for roadway support the present embodiment provides a kind of novel metal stent for roadway support with reference to Fig. 1
Novel metal stent, including rack beam 1 and two oblique pillars 2 for being respectively arranged at 1 both ends of rack beam, gate beam 3
The downside of rack beam 1 is arranged in parallel in, and the both ends of gate beam 3 are respectively articulated with and are arranged on two oblique pillars 2, two
The lower end of auxiliary support plate 4 is articulated with the middle part of gate beam 3, and the upper end of two auxiliary support plates 4 is hingedly connected to stent
The downside at 1 both ends of crossbeam, the upper and lower ends of vertical supporting plate 5 are hingedly connected to the middle part of rack beam 1 and gate beam 3.
Between the both ends of gate beam 3 and oblique pillar 2, between auxiliary support plate 4 and gate beam 3 and rack beam 1,
And be hinged between vertical supporting plate 5 and gate beam 3 and rack beam 1 by articulated joint 6, articulated joint 6 is universal
Hinge.
When it is implemented, the gate beam 3, auxiliary support plate 4 and vertical supporting plate 5 use T-steel harden structure.
