Description
Technical field
A kind of steel canopy of U-shaped steel supported laneway crossover point of the utility model, belongs to technical field of mine support.
Background technology
With the reform and development of colliery roadway engineering support form, arch U-shaped steel collapsible timbering is superior by its
Supporting performance, country rock it is soft, press extensive use in larger roadway.But in use, roadway crossing point uses U
Shaped steel supporting is always construction Difficulties.Construct herein at present frequently with flange beam stand supporting and L-type or U-shaped steel beam supporting, two
The drawbacks of certain all be present in kind method.During using flange beam stand supporting, support overall performance is poor, structural instability, especially
It is in the easy slump deformation of floods medium-height trestle；During using L-type or U-shaped steel beam supporting, a half dome of arched tunnel need to brush flat, and open
Mouth offset section need to be increased to sagitta, considerably increase the pressure from surrounding rock and excavation work amount of crossover point.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided one kind is used for U-shaped steel supported laneway and hands over fork
Stability Analysis of Structures, safe and reliable steel canopy.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of U-shaped steel supported laneway hands over trouble
The steel canopy of point, including support beam, column, support beam both ends are respectively fixedly connected with column, aerial capplce, frame are set above support beam
Empty capplce one end is antiarch shape, and it is horizontal shape to make somebody a mere figurehead the capplce other end, and the horizontal one end of aerial capplce is placed in support beam, frame
One end of empty capplce antiarch shape is connected with U-shaped capplce side, and U-shaped capplce opposite side is connected with canopy leg.
The aerial capplce, U-shaped capplce, canopy leg are connected by card cable.
The aerial capplce, U-shaped capplce, the canopy number of holders of canopy leg composition are multiple.
The utility model has the advantages that compared with prior art：The utility model by aerial capplce with it is U-shaped
Capplce couples, and reduces the complexity of steel canopy difficulty of processing and construction；Aerial capplce is shelved on above support beam, stress is successively
It is delivered to by U-shaped capplce, support beam, column below bottom plate, had both ensured the structural stability of crossover point, and can makes crossover point just
Normal open wind, transport and pedestrian, rational in infrastructure, stability of the roadway, easy construction, safe and reliable, supporting effect is good.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is arrangement schematic diagram of the utility model in tunnel.
1 it is column in figure, 2 be support beam, 3 be canopy leg, 4 be U-shaped capplce, 5 be aerial capplce, 6 is card cable.
Embodiment
As shown in Figure 1 and Figure 2, a kind of steel canopy of U-shaped steel supported laneway crossover point of the utility model, including it is support beam 2, vertical
Post 1, the both ends of support beam 2 are respectively fixedly connected with column 1, and the top of support beam 2 sets aerial capplce 5, and it is antiarch to make somebody a mere figurehead the one end of capplce 5
Shape, it is horizontal shape to make somebody a mere figurehead the other end of capplce 5, and the horizontal one end of aerial capplce 5 is placed in support beam 2, makes somebody a mere figurehead the antiarch shape of capplce 5
One end be connected with the U-shaped side of capplce 4, the U-shaped opposite side of capplce 4 is connected with canopy leg 3；Aerial capplce 5, U-shaped capplce 4, canopy leg 3 are logical
Card cable 6 is crossed to connect；The canopy number of holders that aerial capplce 5, U-shaped capplce 4, canopy leg 3 form is multiple.
The utility model when in use, column 1 is set in crossover point branch entrance to a lane both sides, and column 1 is inserted below roadway floor,
And fixed with both sides wall, the top of column 1 sets support beam 2, and wall certain length is goed deep at the both ends of support beam 2, and using firm
Measure couples with column 1, it is ensured that column 1 forms the stable framework of an entirety with support beam 2, it is sufficient to undertakes at crossover point
Pressure from surrounding rock suffered by steel canopy.U-shaped steel canopy side is consistent with normal reach steel canopy, i.e., canopy leg 3 passes through card cable 6 with U-shaped capplce 4
Connection；U-shaped steel canopy opposite side is coupled using fresh processed aerial capplce 5 with U-shaped capplce 4 by card cable 6.Aerial one end of capplce 5
It is processed into antiarch shape with U-shaped capplce 4 to couple, other end strict level is shelved on the top of support beam 2.According still further to design requirement successively
U-shaped steel canopy and other supporting support patterns of constructing are arranged, U-shaped steel canopy supporting entirety at crossover point is formed, reaches rational in infrastructure, lane
Road is stable, safe and reliable purpose.
During the utility model site operation, the length and support beam 2 of column 1 should be set according to the height of crossover point offset
Highly, it should increase the steel type of column 1 and support beam 2 when ore deposit pressure is larger or use two shaped steel instead and be arranged side by side, to improve knot
The support strength and stability of structure.The form and radius of U-shaped capplce 4 are consistent with normal reach steel canopy, and its length is by crossover point
The height of offset determines.The quantity of card cable 6 is determined by ore deposit pressure and span length, per interface 2 at least, at most 4.In design
The country rock amount of being deformed after tunnelling should be taken into full account, it is ensured that crossover point normally divulges information, transports and pedestrian.This practicality during construction
Supporting support pattern beyond new is essential, to form the complete support system at crossover point, it is ensured that construction quality
With safety.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in those of ordinary skill in the art's possessed knowledge, the utility model aims can also not departed from
On the premise of various changes can be made.
