Abstract
The utility model discloses a bottom wooden beam steel combined bracket for shed, including a trapezoid I steel shed; a bottom wooden beam is arranged at the bottom of the trapezoid I steel shed; the one end of the bottom wooden beam is connected infirmly with the one end of the trapezoid I steel shed, and a clearance is arranged in advance between the other ends of the trapezoid I steel shed and the bottom wooden beam; a strengthening plate is welded at the inner side of the trapezoid I steel shed. The sealed steel combined bracket has the characteristics and the advantages of that as follows: thanks to the bottom wooden beam abuts upon the bottom of a steel shed column, and an oblique triangle armor plate is welded at the inner side of the trapezoid I steel shed to form the strengthening plate, therefore, the lateral compressive strength of the bracket is improved greatly; in addition, owing to two single columns are arranged on the bottom wooden beam, and the two single columns are connected with the bottom wooden beam by means of iron shoes or plastic steel shoes, so the compressive capacity and the end drum capacity of the bracket are improved greatly.
Description
Technical field
The utility model relates to a kind of mine laneway bracing or strutting arrangement, especially sill beam tool steel shed combined bracket.
Background technology:
Along with the increase of the pit mining degree of depth, bury deeply in the coal seam, base plate is soft, press greatly in the ore deposit, even also three-soft seam can occur, and the lower air duct supporting just is the hang-up of puzzlement mine always on the stope.Traditional support form generally is to adopt the tool steel shed supporting of trapezoidal ore deposit, because the effect of geostatic stress, support destroys and is: at first be the ground distension, be then two help to move in the post leg, twisted, stride at last and collapse.
The utility model content
The purpose of this utility model provides a kind of novel structure, compressive strength height, good stability, sill beam tool steel shed combined bracket that anti-pucking ability is strong.
The technical solution of the utility model is: a kind of sill beam tool steel shed combined bracket, comprise trapezoidal tool steel shed, be provided with a wood mudsill in the bottom of trapezoidal tool steel shed, wood beam one end and trapezoidal tool steel shed bottom one end flexibly connect, preset clearance between the other end and the trapezoidal tool steel shed bottom other end is welded with stiffener in trapezoidal tool steel shed inboard.
Stiffener is the oblique triangle of steel plate.
On wood mudsill, be provided with monomer column, the skate inserting on monomer column lower end and the wood mudsill, the monomer column upper end contacts with trapezoidal tool steel shed ceiling.
Monomer column is two.
The utility model pluses and minuses of comparing with conventional stent
1, closed worker's steel sectional shelf-unit characteristics and advantage:
(1) since wood mudsill near the tool steel shed post at the bottom of and add welding steel plate oblique triangle in the inboard of trapezoidal tool steel shed beam and become stiffener, greatly improved the lateral pressure resistant intensity of support; (2) owing on wood mudsill, adorn two monomer columns, and to wear skate between monomer column and the wooden frame or the plastic-steel footwear are connected, greatly improve the anti-roof pressure and the pucking ability of support.
2, the shortcoming of traditional trapezoidal tool steel shed supporting and failure mechanism:
(1) along with the increasing of mining depth, geostatic stress also increases thereupon, and especially level sharply increases, and is subjected to the effect of horizontal stress and vertical stress, moves the twisted last destruction of tool steel shed in the worker's steel column of trapezoidal tool steel shed both sides.
(2) traditional trapezoidal tool steel shed supporting is opening to roadway floor, at all without any the measure that prevents and treats end distension.
" repair after the preceding pick, the preceding back of repairing is bad " often appears in the trapezoidal tool steel shed supporting of the many employings of the coal road in ore deposit, past Henan Province's Jiaozuo City Gu Han mountain, repaiied and repaiied, and maintenance cost is huge.Total input in every meter tunnel reaches more than 3000 yuan, still can not tackle the problem at its root, and directly influences the exploiting field and normally takes over.
Adopt closed trapezoidal tool steel shed supporting, through overtesting, respond well.Facts have proved, can not only solve a supporting difficult problem once and for all, and its supporting one cost is minimum.With regard to ore deposit, Gu Han mountain, the economic benefit preresearch estimates of its generation is annual more than 5,000,000 yuan.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model structure is as shown in Figure 1: traditional trapezoidal tool steel shed by crossbeam 2 and about two curb girders 3 form, bottom at the trapezoidal tool steel shed of tradition increases a wood mudsill 1, wood mudsill becomes sleeper shape, one end and trapezoidal tool steel shed one quarter pillar bottom flexibly connect, the other end can and trapezoidal tool steel shed opposite side beam column bottom group post between reserve some apart from forming the gap, as the usefulness of reserving the ditch, constitute incomplete enclosed type tool steel shed combined bracket, at the tool steel shed beam inboard is added the oblique triangle of steel plate of weldering 4 as stiffener, beam is come off extruding in case side pressure is excessive.Add on wood mudsill and make a call to two monomer columns 6, the monomer column lower end is connected with skate 5 or the inserting of plastic-steel footwear on being packed in wood mudsill, and the monomer column upper end contacts with trapezoidal tool steel shed ceiling crossbeam 2.
Claims (4)
1, a kind of sill beam tool steel shed combined bracket, comprise trapezoidal tool steel shed, it is characterized in that: be provided with a wood mudsill in the bottom of trapezoidal tool steel shed, wood beam one end and trapezoidal tool steel shed bottom one end flexibly connect, preset clearance between the other end and the trapezoidal tool steel shed bottom other end is welded with stiffener in trapezoidal tool steel shed inboard.
2, sill beam tool steel shed combined bracket according to claim 1, it is characterized in that: stiffener is the oblique triangle of steel plate.
3, sill beam tool steel shed combined bracket according to claim 1 is characterized in that: on wood mudsill, be provided with monomer column, and the skate inserting on monomer column lower end and the wood mudsill, the monomer column upper end contacts with trapezoidal tool steel shed ceiling.
4, sill beam tool steel shed combined bracket according to claim 3, it is characterized in that: monomer column is two.
