Description
Technical field
It the utility model is related to the technical field of tunnel support, more particularly to a kind of U-shaped steel canopy support.
Background technology
During mining construction, complicated hydrogeological conditions, difficulty of construction is big, easily deforms, damages after tunnelling construction
Bad, Floor Heave in Roadway is very fast, and track deformation is serious, and the canopy of steel soon of erection is influenceed by ground pressure, it is easy to occur it is different degrees of by
Compressive strain.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of U-shaped steel canopy support.
The technical solution of the utility model is：A kind of U-shaped steel canopy support, including back timber, bottom girder and two are symmetrically arranged
Supporting leg, the back timber are convex arcuate structure, and the supporting leg includes the straight of arch section above and indent and lower section
Line part, bottom girder arcuate structure convex under being, the both ends of the back timber are welded with has a spacing positioned at inner side and away from end
From limited block, the arch section of two supporting legs is located at the lower section of the limited block and is overlapped on the both ends of the back timber,
With fixed after back timber overlap joint, the straight line portion of two supporting legs is fixedly connected the supporting leg with the both ends of the bottom girder.
Preferably, the supporting leg after one end overlap joint of the back timber with least two card cables with being fixed.
Preferably, the lap of splice of the supporting leg and the back timber is 500mm, the limited block and the supporting leg upper end
Distance be 30mm.
Preferably, the lower end of the supporting leg is fixed with connecting plate first with threaded hole, and the both ends of the bottom girder are fixed with band
The connecting plate second of screwed hole, the connecting plate first are connected with after being docked with the connecting plate second.
The beneficial effects of the utility model are：
U-shaped steel canopy support of the present utility model, supporting leg is connected with back timber using overlapping mode, there is certain buffering to make
With, prevent steel canopy support be pressurized；There is provided limited block, the position of positioning support leg is capable of in overlap joint, and it is spacing when being pressurized
Block can also limit the position of back timber, reserve buffer distance；Supporting leg and back timber are fixed with card cable, and supporting leg and bottom girder pass through connection
Plate first and connecting plate second are connected with, and are easy for installation and removal.

Embodiment
Specific embodiment of the present utility model is referring to Fig. 1-3：
The utility model mainly discloses a kind of U-shaped steel canopy support, with the schema hereinafter compareed, main expression and this reality
With the relevant structural representation of novel feature, also need not completely it not drawn according to actual size, first explanation.
A kind of U-shaped steel canopy support, such as Fig. 1-3, including back timber 1, bottom girder 3 and two symmetrically arranged supporting legs 2, the back timber
1 is convex arcuate structure, and the supporting leg 2 includes arch section above and indent and the straight line portion of lower section, described
The arcuate structure convex under being of bottom girder 3, the both ends of the back timber 1 are welded with the limited block for having certain distance positioned at inner side and away from end
11, the arch section of two supporting legs 2 is located at the lower section of the limited block 11 and is overlapped on the both ends of the back timber 1, described
With fixed after the back timber 1 overlap joint, the straight line portion of two supporting legs 2 is fixedly connected supporting leg 2 with the both ends of the bottom girder 3,
Supporting leg 2 and back timber 1 are connected using overlapping mode, there is certain cushioning effect, prevents steel canopy support to be pressurized；There is provided limited block
11, the position of positioning support leg 2 is capable of in overlap joint, and limited block 11 can also limit the position of back timber 1 when being pressurized, and reserve
Go out buffer distance.
In order to facilitate installation and removal, fixed after one end overlap joint of the supporting leg 2 with back timber 1 with least two card cables 4.
Heading sizes and be under pressure size, the lap of splice of supporting leg 2 and back timber 1 be set to 500mm, make limited block 11 with
The distance of the upper end of supporting leg 2 is 30mm.
In order to facilitate installation and removal, connecting plate first with threaded hole is fixed in the lower end of supporting leg 2, at the both ends of bottom girder 3
Fixed connecting plate second with threaded hole, is connected with after connecting plate first is docked with connecting plate second.
