Abstract
The invention discloses a short stand column shrinkable shed bracket. The short stand column shrinkable shed bracket comprises a top beam, a combined short stand column, and a stand column base mounted on a roadside, wherein the stand column base consists of a base body, a chassis and a circular pad and a cushion block for fixing the base body on the roadside; and the stand column base is firmly mounted in the upper parts of two sides of a roadway through two sets of four first-grade round steel and second-grade round steel embedded and inserted in pre-drilled holes to build the bracket. Compared with a no-stand-column shed built by an altitude hole drilling method, on the basis of keeping the advantages, the short stand column shrinkable shed bracket increases excellent shrinkability; and the method for embedding and inserting the round steel in the drilled holes is used for installing to reduce the influence from the limitations of roadside rock stability degree, so that the short stand column shrinkable shed bracket is wider in application, and a certain economical benefit is brought.
Description
Technical field
The present invention relates to mine roadway support technical field, particularly one short column contractibility canopy cribbing.
Background technology
Canopy cribbing, is also called trapezoid support, and it is made up of slightly toward the column that tunnel is centroclinal a back timber and two, and the supporting as mine laneway uses.When two of tunnel helps (hereinafter referred to as lane side) enough firm, can not column be used, and directly take to hole at the place of side, lane of back timber end positions, utilize it by the get off supporting roof of direct for back timber frame at top board, become without column shed.Although above-mentioned setting saves support material, reduces tunnel cutting amount and favourable dash, there is not tunnel yet and use the drawback that column can be knocked over time non-rail-based conveyor system (as scraper).But its needs to hole in the eminence of lane side, and difficulty of construction is large, and its back timber also lacks contractibility simultaneously, use during most temporary lining only in tunnel at mine construction with in producing.
But, lack a kind of support in the prior art, can solve without column shed Problems existing.
Summary of the invention
Object of the present invention, to be for above-mentioned, without column shed Problems existing, to provide a kind of short column contractibility canopy cribbing.
Short column contractibility canopy cribbing of the present invention, " retractable trapezoid support with cushion blocks " (CN102493824A is formed by a back timber and two short columns of combined type, on June 13rd, 2012 announces) based on, the transverse direction at removing back timber two ends can contracting body, column is shortened simultaneously, change the shaft of column into suspension column, significantly reduce strut length and become short column, and help appropriate position in lane and install Upright post base and hold column, structure forms.
Short column contractibility canopy cribbing of the present invention, comprises back timber, the short column of combined type and Upright post base, the short column support of combined type be located at be installed on roadway's sides top Upright post base on.The short column of combined type is combined by column cap and suspension column, and its length is less than 1/3rd of head-room, and one-level round steel, secondary round steel and cushion block that Upright post base is helped in lane by pedestal, chassis, fixed base frame form.Chassis channel-section steel and steel plate are made, and weld on pedestal; It is the same that pedestal comprises two structures, and be parallel to each other, distance is slightly larger than the oblique trouble of the horizontal corner steel of suspension column width and two at 45 ° ~ 60 of oblique angle steel welding °, right angle, horizontal corner steel two ends section is welded the fixing angle steel cooperatively interacted with section, and fixing angle steel is provided with the through hole cooperatively interacted with horizontal corner steel square position; One-level round steel and secondary round steel, respectively to bury solid and freely to insert and be fixed on lane and help in the hole of Drilling in advance; One-level round steel is in the outside termination of lane side and is installed near lane side by pedestal by fastening nut, secondary round steel is shelved with the cushion block that channel-section steel is made, for supporting oblique angle steel.
The present invention's short column contractibility canopy cribbing, when erection is installed, one-level round steel and secondary round steel buried solid respectively and insert in the hole of place of side, lane Drilling in advance, cushion block is placed on secondary round steel, is enclosed within by pedestal on one-level round steel, use nut screwing clamping, oblique angle steel supports on cushion block, Upright post base is installed in lane and helps, and is placed on chassis afterwards by suspension column, erect the short column of combined type and back timber, finally by adjustment combined type short column height and backboard is installed by canopy cribbing frame jail.
Beneficial effect of the present invention: short column contractibility canopy cribbing is being possessed on the basis without column shed advantage, makes support have good contractibility energy, improves the supporting effect of support, the restriction by lane side soundness is less; Less, more convenient to operate in position boring difficulty of construction compared with holing aloft of about 2/3rds, make the applicability of short column contractibility canopy cribbing wider, certain economic benefit will be brought.

Fig. 1 is the structural representation of the present invention's short column contractibility canopy cribbing;
Fig. 2 is the partial enlarged drawing of A in Fig. 1;
Fig. 3 is the lateral view of Fig. 2.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: the short column 2 of back timber 1, combined type, Upright post base 3, column cap 21, suspension column 22, chassis 31, fixing angle steel 32, one-level round steel 33, nut 34, horizontal corner steel 35, oblique angle steel 36, cushion block 37, secondary round steel 38, one-level hole 41, second hole 42.
As shown in Figure 1: short column contractibility canopy cribbing, comprises back timber 1, the short column 2 of combined type and the Upright post base 3 being installed in roadway's sides top, the short column 2 of combined type comprises 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, secondary round steel 38 and cushion block 37 that Upright post base 3 is helped in lane by pedestal, chassis 31, fixed base frame form.Chassis 31 channel-section steel and steel plate are made, and weld on pedestal; Pedestal welds oblique trouble at 45 ° by two horizontal corner steels 35 and two oblique angle steel 36, right angle, horizontal corner steel 35 two ends section is welded the fixing angle steel 32 cooperatively interacted with section, and fixing angle steel 32 is provided with the through hole cooperatively interacted with horizontal corner steel 35 square position; One-level round steel 33 and secondary round steel 38, be fixed in the one-level hole 41 and second hole 42 of helping Drilling in advance in lane to bury mode that is solid and that freely insert respectively; The termination that one-level round steel 33 is in lane side outside is threaded with nut 34, secondary round steel 38 is shelved with the cushion block 37 that channel-section steel is made.
Short column contractibility canopy cribbing of the present invention, first by the one-level round steel 33 of the pedestal of Upright post base 3 through top, and the oblique angle steel 36 on pedestal is positioned on cushion block 37, if desired filling mat is set on cushion block 37, then fastening nut 34, is installed in lane by Upright post base and helps, and can stand on Upright post base 3 by short for combined type column 2 afterwards, by adjusting the height of the short column 2 of combined type and installing backboard, by its jail.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
