Abstract
The invention provides underground coal mine rectangular shaped roadways branch protecting assembly, including back timber, back timber support base, Semicircular arched U-shaped steel canopy, diagonal brace and column, characterized in that, the back timber both ends are directly caught in back timber support base, the back timber support base is fixed with column and welds and be connected diagonal brace.The present invention is used for colliery rectangular shaped roadways, and when tunnel is in the range of high stress, component external component deforms, and does not interfere with internal Semicircular arched U-shaped steel canopy net sectional area, can ensure tunnel normal use, road maintenance amount greatly reduces.
Description
Technical field
The present invention relates to roadway support, and in particular to underground coal mine rectangular shaped roadways branch protecting assembly.
Background technology
Coal mining progressively develops to deep, and strata behaviors is further violent, and roadway support support action is more prominent, and in roadway support section, rectangular cross section utilization rate is high, but resistance to compression and anti-shear ability are weaker compared with semicircular arch and other shapes of section.In the prior art, strengthening supporting is carried out in high stress location using Semicircular arched U-shaped steel canopy more, in Semicircular arched section, Semicircular arched U-shaped steel canopy can play larger effect, but in rectangular shaped roadways, because Semicircular arched U-shaped steel canopy and rectangular shaped roadways top plate can not completely attach to, filled using modes such as backboards, the yielding destruction of top plate, cause U-shaped steel canopy to be bent deformation, heading sizes do not meet the generation of the safety problems such as safety requirements, last supporting failure.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned the deficiencies in the prior art, there is provided underground coal mine rectangular shaped roadways branch protecting assembly.
In order to solve the above technical problems, the technical solution adopted by the present invention is：Underground coal mine rectangular shaped roadways branch protecting assembly, including back timber, back timber support base, Semicircular arched U-shaped steel canopy, diagonal brace and column, it is characterised in that the back timber both ends are directly caught in back timber support base, and the back timber support base is fixed with column and welds and be connected diagonal brace.
The branch protecting assembly is all process using U-shaped steel；The back timber integrally contacts with back；The back timber support base quantity is 2,600 ~ 800mm of length, opening upwards.
The column is welded with back timber support base, 102 ~ 105 ° of angle；The diagonal brace is to measure 500 ~ 700mm from both ends with back timber support base and column welding position.
The present invention is used for colliery rectangular shaped roadways, component back timber can be made to realize that face contacts with back, with preferable supporting effect, when tunnel is in the range of high stress, component external component deforms, internal Semicircular arched U-shaped steel canopy net sectional area is not interfered with, tunnel normal use can be ensured, maintenance capacity greatly reduces.

Fig. 1 is the structure chart of the present invention.
Description of reference numerals：
1- back timbers；2- back timber support bases；3- Semicircular arched U-shaped steel canopies；4- diagonal braces；5- columns.
Embodiment
As shown in figure 1, the present invention includes back timber 1, back timber support base 2, Semicircular arched U-shaped steel canopy 3, diagonal brace 4 and column 5, it is characterised in that the both ends of back timber 1 are directly caught in back timber support base 2, and the back timber support base 2 is fixed with column 5 and welds and be connected diagonal brace 4.
The branch protecting assembly is all process using U-shaped steel；The quantity of back timber support base 2 is 2, length 700mm, opening upwards.
The column 5 is welded with back timber support base 2,102 ° of angle；The diagonal brace 4 and support base 2 and the welding position of column 5,600mm is measured from both ends.
Every any simple modification, change and equivalence change substantially made according to the technology of the present invention to above example, are still within the scope of the technical scheme of the invention.
