Description
Technical field
The utility model relates to the underground engineering supports field such as tunnel, chamber, tunnel, especially a kind of improvement support pattern
U-shaped steel bracket.
Background technique
During mine laneway and construction of underground tunnel, top plate fall off and two help large deformation be influence construction safety most
One of main several factors arrange U-shaped steel bracket generally in tunnel, prevent lane to implement the support to tunnel palisades
The surrouding rock deformation in road.But current mine laneway wall surface all out-of-flatnesses, when carrying out supporting using U-shaped steel bracket, country rock is pressed
It can make stress concentration occur with wall face contact holder part, when the country rock acted on U-shaped steel bracket reaches certain value,
Bracket can destroy.This drift support type security performance is lower.Therefore, it is necessary to one kind sufficiently to connect with tunnel wall surface
Touching, thus the supporting construction of uniform force.
Utility model content
The purpose of this utility model is to provide a kind of U-shaped steel brackets for improving support pattern.
The purpose of this utility model is achieved through the following channels: a kind of U-shaped steel bracket improving support pattern, the branch
Frame is that prop composition is equipped on U-shaped steel bracket；The U-shaped steel bracket includes top beam, column leg, top beam and column leg
Both ends are connected through a screw thread；U-shaped steel rack outer surface pastes respectively from the inside to the outside is equipped with prop and fitting branch sheath；Institute
The fitting branch sheath stated is the internal bag for being filled with concrete.
It is fixed with support column by being embedded to bottom plate below the U-shaped steel bracket as a further optimization of the solution, is propped up
One end of two support rods in left and right is screwed at the top of dagger, the other end of support rod puts on compressed spring rear enclosure into card cable
Sets of holes in, the card cable is movably installed on top beam.
A kind of U-shaped steel bracket for improving support pattern of the utility model, it is highly-safe, it can be come into full contact with tunnel wall surface,
To uniform force.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing:
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model U-shaped steel end structure schematic diagram；
Fig. 3 is the utility model A-A the schematic diagram of the section structure；
In figure, top beam 1, column leg 2, prop 3, fitting branch sheath 5, connecting sleeve 6, elastic washer 7, support column 8, pressure
Contracting spring 9, support rod 10, card cable 11.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of U-shaped steel bracket for improving support pattern of the utility model, which is U-shaped
The composition of prop 3 is installed on steel bracket；The U-shaped steel bracket includes top beam 1, column leg 2, the both ends of top beam 1 and column leg 2
It is connected through a screw thread；U-shaped steel rack outer surface pastes respectively from the inside to the outside is equipped with prop 3 and fitting branch sheath 5；It is described
Fitting branch sheath be the internal bag for being filled with concrete.
It is fixed with support column 8 by being embedded to bottom plate below the U-shaped steel bracket, is screwed at the top of support column 8
One end of two support rods 10 in left and right, the other end of support rod 10 put on 9 rear enclosure of compressed spring into the sets of holes of card cable 11, described
Card cable 11 be movably installed on top beam 1.
When installation, first the both ends of top beam 1, column leg 2 are overlapped, put on elastic washer 7 respectively at connection end, so
Top beam 1 and the end of column leg 2 are fixed simultaneously by rotating clockwise connecting sleeve 6, are assembled into U-shaped by rear enclosure upper joint sleeve pipe 6
Then steel bracket is sleeved on U-shaped steel stent outer surface according to shape correspondence for every section of prop 3, then will be bonded supporting
Layer 5 is placed on prop 3, and card cable 11 is with the left and right section that vault is that middle point symmetry is fixed on top beam 1, later by support column 8
Bottom plate of nuzzling is fixed, and one end of two support rods 10 is fixed on to the end of support column 8 by screw, on other end set
Then compressed spring 9 packs into the sets of holes of card cable 11, so that the both ends of support rod 10 is capable of fixing and is played support to U-shaped steel and make
With.When carrying out roadway support, the placing concrete in fitting branch sheath 5 makes its filling expansion, then passes through rotation connecting sleeve 6
Increase the contact area of fitting branch sheath 5 and tunnel wall surface, is squeezed tunnel wall surface to mention right, general lane
Road roof deformation is more serious, so the supporting to vault is reinforced, card cable 11 can adjust position in vault, to make
Support rod 10 rotates angle to 1 strengthening supporting of vault centered on support column 8.When tunnel deforms, U-shaped steel bracket can stress
It uniformly can utmostly play its supporting effect, support rod 10 can allow pressure and supporting to back pressure is carried out.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art, can be without creative labor in the technical scope disclosed by the utility model
The dynamic change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection model of the utility model
Enclosing be determined by the scope of protection defined in the claims.
