Abstract
This patent discloses a kind of short column contractibility canopy formula support, including the short column of back timber, combined type and the Upright post base being installed on lane side；Upright post base is made up of pedestal, chassis, fixed base frame in the round steel and cushion block of lane side, and it amounts to 4 by two groups and buries one-level round steel and two level round steel solid, be inserted in advance drilling holes respectively, the upper position of roadway's sides is fixedly attached to, to erect support.Compared with the method erection that holed using eminence is without column shed, on the basis of its advantage is possessed, add good contractibility, the method for burying, inserting round steel using drilling is installed, reduce is influenceed by the limitation of lane side Rock Mass Stability degree, make the application of short column contractibility canopy formula support wider, certain economic benefits will be brought.
Description
Technical field
The present invention relates to mine roadway support technical field, more particularly to a kind of short column contractibility canopy formula support.
Background technology
Canopy formula support, also known as trapezoid support, it is slightly to the centroclinal column group in tunnel from a back timber and two
Into the supporting as mine laneway uses.Two when tunnel help（Hereinafter referred to as lane side）When firm enough, understand without using column,
And directly take and holed at the lane side of back timber end positions, using it by the direct frame of back timber under top plate come supporting roof,
As without column shed.Although above-mentioned setting saves support material, reduces tunnel cutting amount and favourable dash, also do not deposit
Non- rail-based conveyor system is used in tunnel（Such as scraper）When the drawbacks of column being knocked over.It require that the eminence in lane side is dug
Hole, difficulty of construction is big, while its back timber also lacks contractibility, most only in the gib in tunnel in mine construction and production
When use.
But lack a kind of support in the prior art, can solve the problems, such as that no column shed is present.
The content of the invention
The purpose of the present invention, the problem of being to exist for above-mentioned no column shed, there is provided a kind of short column contractibility canopy
Formula support.
The short column contractibility canopy formula support of the present invention, is made up of a back timber and two short columns of combined type《Dress
Cushion contractibility trapezoid support》（CN102493824A, on June 13rd, 2012 announce）Based on, the transverse direction at removing back timber both ends
Can contracting body, while column is shortened, the shaft of column is changed to suspension column, strut length, which is greatly decreased, turns into short column, and in lane
Help appropriate position and install Upright post base and hold column, construction forms.
The short column contractibility canopy formula support of the present invention, including the short column of back timber, combined type and Upright post base, combined type are short vertical
Pylon, which is located at, to be installed on the Upright post base on roadway's sides top.The short column of combined type is combined by column cap and suspension column, its length
Less than 1/3rd of head-room, one-level round steel, two level round steel of the Upright post base by pedestal, chassis, fixed base frame on lane side
And cushion block composition.Chassis is made of channel-section steel and steel plate, is welded on pedestal；Pedestal includes two constructions equally, and is parallel to each other,
Distance is at 45 ° slightly larger than the horizontal corner steel of suspension column width and two oblique angle steel welding ~ and 60 ° of oblique trouble is straight at horizontal corner steel both ends
The fixation angle steel to be cooperated with section is welded on the section of angle, fixed angle steel is provided with and horizontal corner steel square position phase interworking
The through hole of conjunction；One-level round steel and two level round steel, it is fixed on respectively with burying admittedly and being inserted freely on lane side in the hole of advance Drilling；One
The termination that level round steel is in outside lane side is installed pedestal against lane side by tightening nut, and channel-section steel system is shelved with two level round steel
Into cushion block, for supporting oblique angle steel.
The short column contractibility canopy formula support of the present invention, when installation is set up, by one-level round steel and two level round steel bury respectively it is solid and
Insert at lane side in the hole of advance Drilling, cushion block is placed on two level round steel, and pedestal is enclosed on one-level round steel, twisted using nut
Tightly, oblique angle steel is supported on cushion block, and Upright post base is installed on lane side, and suspension column is placed on chassis afterwards, erects combined type
Short column and back timber, finally by the height for adjusting the short column of combined type and backboard is installed by canopy formula support frame jail.
Beneficial effects of the present invention：Short column contractibility canopy formula support makes on the basis of no column shed advantage is possessed
Support has good contractibility energy, improves the supporting effect of support, is limited by lane side soundness smaller；Three/
Two or so opening position drills, and the difficulty of construction compared with aloft holing is smaller, and operation is more convenient, makes short column contractibility canopy
The applicability of formula support is wider, will bring certain economic benefit.
Brief description of the drawings
Fig. 1 is the structural representation of the short column contractibility canopy formula support of the present invention；
Fig. 2 is the partial enlarged drawing of A in Fig. 1；
Fig. 3 is Fig. 2 side view.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：The short column 2 of back timber 1, combined type, Upright post base 3, column cap 21, suspension column 22,
Chassis 31, fixed angle steel 32, one-level round steel 33, nut 34, horizontal corner steel 35, oblique angle steel 36, cushion block 37, two level round steel 38, one
Level hole 41, second hole 42.
As shown in Figure 1：Short column contractibility canopy formula support, including back timber 1, the short column 2 of combined type and are installed in tunnel two
The Upright post base 3 in portion is helped, the short column 2 of combined type includes column cap 21 and suspension column 22, and its length is 1/3rd of head-room.
As shown in Fig. 2 ~ 3：One-level round steel 33, two level circle of the Upright post base 3 by pedestal, chassis 31, fixed base frame on lane side
Steel 38 and cushion block 37 form.Chassis 31 is made of channel-section steel and steel plate, is welded on pedestal；Pedestal is by two Hes of horizontal corner steel 35
