The utility model proposes the device that wire netting is supported in a kind of tunnel shotcrete rock bolt wire mesh support, including support block, adjustable screw, long nut, base, the adjustable screw bottom is screw rod variable partition, it is fastening force section on screw rod variable partition, base is fixed on base in bottommost, long nut, and screw rod adjustable section sets up screw thread separately, long nut is to be threadedly coupled cooperation with screw rod variable partition, and support block is held out against at the top of adjustable screw.The utility model beneficial effect is：Easy to use, bearing length is easily adjusted, Area of bearing is big, reduces labor strength.
Description
Technical field
The utility model belongs to Combined bolting and shotcrete method field, is related to the dress that wire netting is supported in the shotcrete rock bolt wire mesh support of tunnel
Put.
Background technology
Combined bolting and shotcrete method is applied to the tunnel of rock crusher.Construction technology is generally：Wire netting-installation anchor is installed
Bar-gunite concrete.When wire netting is installed, need that wire netting is temporarily manually close into scar, usually using the fixed support of frame wood
Wire netting.Because frame wood bearing length is not easy to adjust, Area of bearing is small, labor strength is big.
Utility model content
The purpose of the utility model is to propose a kind of wire netting support meanss easy to use, support effect is good.
The technical solution adopted in the utility model is：The device of wire netting is supported in a kind of tunnel shotcrete rock bolt wire mesh support, including
Support block, adjustable screw, long nut, base, the adjustable screw bottom are screw rod variable partition, screw rod adjustable section
/ upper to fasten force section, base is fixed on base in bottommost, long nut, and screw rod adjustable section sets up screw thread, long spiral shell separately
Mother is to be threadedly coupled cooperation with screw rod variable partition, and support block is held out against at the top of adjustable screw.
Further, it is additionally provided with deep floor between the base and long nut.
Preferably, the fastening force section is prismatic, for placing spanner.
Further, it is connected with the fastening force section and screws bar, screw bar axially above axially has with fastening force section
Angle, when being exerted oneself to screwing bar, produce moment of torsion and make fastening force section rotation.
Preferably, the described bar one end that screws is hinged in fastening force section.
The utility model beneficial effect is：Easy to use, bearing length is easily adjusted, Area of bearing is big, reduces worker's work
Intensity.

Embodiment
As shown in figure 1, the device of wire netting is supported in a kind of tunnel shotcrete rock bolt wire mesh support, including support block 1, adjustable screw
2nd, long nut 5, base 7, the bottom of adjustable screw 2 are screw rod variable partition 4, are tight on screw rod variable partition 4
Gu exert a force section 3, base 7 is fixed on base 7 in bottommost, long nut 5, and screw rod variable partition 4 sets screw thread, long nut 5 with
Screw rod variable partition 4 is that threaded connection coordinates, and the top of adjustable screw 2 holds out against support block 1.
To ensure the reliability between base 7 and long nut 5, deep floor 6 is additionally provided between base 7 and long nut 5.
Fastening force section 3 can be prismatic, and by spanner clamping, moment of torsion is firmly produced to spanner.
It in order to be more convenient, can also be worked without spanner, structure as shown in Figure 2 and Figure 3 can also be used, connected in fastening force section 3
It is connected to and screws bar 8, screw bar 8 axially above axially has angle with fastening force section 3.Further, the one end of bar 8 is screwed to be hinged on tightly
Gu being lifted in the section 3 that exerts a force, during use and screwing bar 8, when being exerted oneself to screwing bar, and producing moment of torsion makes fastening force section rotation.
Correct position is selected, this is placed in below wire netting, spanner is placed on spanner fastening area, spanner is reconciled and turns to,
The part that screw rod variable partition 4 can be made to stretch out outside long nut 5 extends or shortened, and the top of adjustable screw 2 holds out against support
Block 1, wire netting is set to be close to scar using upper support block.
