Abstract
The utility model relates to an anchor rod supporting plate assorted with a steel bar supporting beam for use. The anchor rod supporting plate is characterized by comprising a platelike supporting plate body; the central part of the supporting plate body is provided with an anchor rod mounting hole, and the back surface of the supporting plate body, close to two opposite edges, is respectively provided with grooves which are parallel and correspond to two main bars of the steel bar supporting beam. The anchor rod supporting plate has the advantages that after prestress is applied to the anchor rod supporting plate assorted with the steel bar supporting beam for use, the stress can spread to the rock surface fast; and although failing, the welding parts of the steel bar supporting beam are still in the two grooves, thus guaranteeing the action of the supporting beam. When being used for roadway support, the anchor rod supporting plate has simple technique, can greatly improve supporting effect, and can guarantee the safety of supporting of roadways and side slopes.
Description
Technical field
The utility model relates to a kind of and the matching used Supporting plate for anchor of reinforcing bar joist, is mainly used in the supporting of roadway bolt under the coal mine.
Background technology
In the roadway supported by bolt of China's coal-mine down-hole, most reinforcing bar ladder beams that use are as anchor member at present, and the anchor pole pallet is pressed in reinforcing bar joist top, then anchor pole is applied prestressing force.There is following shortcoming in this anchor pole pallet: the pallet below is the reinforcing bar joist, when anchor pole is applied prestressing force, owing to have only twice reinforcing bar contact scar, therefore is line contact, Stress Transfer weak effect between terraced beam and the scar.Reinforcing bar ladder beam strength is low in addition, tears in the welding position easily.
Summary of the invention
The purpose of this utility model is to provide a kind of and the matching used Supporting plate for anchor of reinforcing bar joist, to solve pallet below that prior art exists when adopting the reinforcing bar joist that anchor pole is applied prestressing force, owing to have only twice reinforcing bar contact scar, therefore be the line contact between terraced beam and the scar, the Stress Transfer weak effect, reinforcing bar ladder beam strength is low, easily the problem of tearing in the welding position.
The technical solution of the utility model is: comprise tabular supporting plate main body, central authorities in this supporting plate main body are provided with the anchor pole installing hole, at the back side of this supporting plate main body near relative both sides be respectively equipped be parallel to each other and with two main muscle corresponding groove of described reinforcing bar joist.
To the positive projection of supporting plate main body, this anchor pole installing hole inboard is recessed arc surface around the described anchor pole installing hole.
Described supporting plate main body is a rectangle.
The utility model has the advantages that: after this and the matching used Supporting plate for anchor of reinforcing bar joist were applied prestressing force, stress can be diffused into scar rapidly; Even reinforcing bar joist welding position still in two grooves, had guaranteed the effect of joist after losing efficacy.Carry out roadway support with the utility model, technology is simple, and supporting effect can be greatly improved, and can ensure the safety of tunnel, slope retaining.

The specific embodiment
Referring to Fig. 1～Fig. 5, the utility model is the special supporting design of existing reinforcing bar joist (referring to Fig. 4) that is, this reinforcing bar joist is by two parallel main muscle 5 and be vertically connected on two reinforcing bar cross ribs 6 between the main muscle 5 and form.The utility model comprises the tabular supporting plate main body 1 of rectangle (comprising square), central authorities in this supporting plate main body 1 are provided with anchor pole installing hole 4, at the back side of this supporting plate main body 1 near relative both sides be respectively equipped be parallel to each other and with two main muscle 5 corresponding groove 2 of reinforcing bar joist.Groove 2 can be being bent to form by supporting plate main body 1.
To the positive projection of supporting plate main body 1, the inboard of this anchor pole installing hole 4 is recessed arc surface 8 around the described anchor pole installing hole 4.
Described reinforcing bar cross rib 6 lays respectively at the right and left of the present utility model (both sides respectively have two or more than two reinforcing bar cross ribs 6), is used for spacing to supporting plate main body 1.
To a side projection 3 in the front of supporting plate main body 1, the inboard of this anchor pole installing hole 4 is recessed arc surface 8 around the described anchor pole installing hole 4.The anchor pole installing hole 4 of arc surface coincide mutually with the arc end of the packing ring of skyhook when using, reduce since the bending force of tunnel air spots generation to the influence of anchor pole.
The utility model is when using (with reference to figure 4 and Fig. 5), the reinforcing bar joist of being made up of main muscle 5 and reinforcing bar cross rib 6 is arranged on the surface of tunnel rock 7, supporting plate main body 1 of the present utility model is installed in the outside of reinforcing bar joist, and two main muscle 5 are placed in two grooves 2 of supporting plate main body 1, and each supporting plate main body 1 is placed between the reinforcing bar cross rib 6.Be used for skyhook (not shown) in the anchor pole installing hole 4 of Supporting plate for anchor 1.
Claims (3)
1, a kind of and matching used Supporting plate for anchor of reinforcing bar joist, it is characterized in that: comprise tabular supporting plate main body, central authorities in this supporting plate main body are provided with the anchor pole installing hole, at the back side of this supporting plate main body near relative both sides be respectively equipped be parallel to each other and with two main muscle corresponding groove of described reinforcing bar joist.
2, the according to claim 1 and matching used Supporting plate for anchor of reinforcing bar joist is characterized in that: to the positive projection of supporting plate main body, this anchor pole installing hole inboard is recessed arc surface around the described anchor pole installing hole.
