Abstract
The utility model discloses a steel and bamboo combined anchoring-bolt, which is composed of an anchoring-bolt body, a connecting plate, a pallet, and a wedge. The anchoring-bolt is made of bamboo boards, one end of the anchoring-bolt forms a dovetail shape, the connecting plate is made of steel plates, the anchoring-bolt and one end of the connecting plate is riveted with ferric wires, and the other end of the connecting plate is provided with a pin hole. Compared with a metallic anchoring-bolt, cost is reduced by 50% or more, and steels are saved by 70% or more. Compared with a common bamboo anchoring-bolt, anchoring force is enhanced by 80% or more, the steel and bamboo combined anchoring-bolt solves better the connecting mode of the anchoring-bolt head of the bamboo anchoring-bolt, and mechanical properties of bamboos fully exert. The utility model is suitable for popularization and use in mines.
Description
The utility model belongs to the anchor pole of in a kind of mining engineering soft rock roadway support being used.
To adopt anchor rod anchored be one of the effective measures of supporting roadway surrounding rock for the zone of fracture of rock stratum, avalanche band in the mining engineering field.Adopting anchor rod anchored in weak stratum is the supporting method of promoting in recent years.In prior art, used the anchor pole of various structures,, form by bamboo anchoring-bolt body, wooden block dish, chock, double-quick cement volume, but anchored force has been little, wooden block dish destructible, is subjected to digging laneway to influence chock and easily falls, and loses anchored force as pure bamboo anchoring-bolt.The bonding anchor pole of another kind of steel bamboo is made up of bamboo anchoring-bolt body, pallet, gusset piece, double-quick cement volume, hold-down nut, but the cost height, crudy is influenced greatly by activities, workman's technical level and sense of responsibility, and the anchored force instability of anchor pole.The prior art anchor pole can not be given full play to the mechanical property of bamboo wood, and anchored force is little can not to satisfy the requirement of reinforcing country rock.
In view of the deficiency that above-mentioned existing anchor pole technology exists, the utility model provides a kind of mechanical property of giving full play to bamboo wood, and is rational in infrastructure, improves the steel bamboo assembled bolt of anchored force.
To achieve these goals, the utility model reaches by following scheme.Steel bamboo assembled bolt is made up of anchor bar body, gusset piece, pallet, chock.Its architectural feature is: an end of anchor bar body is dovetail shaped, and the other end is connected with gusset piece, has pin-and-hole at the head of gusset piece, and chock inserts in the pin-and-hole and contacts with the pallet that is enclosed within the gusset piece end.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The front view of the structural representation of the steel bamboo assembled bolt that Fig. 1 provides for the utility model.
The vertical view of the structural representation of the steel bamboo assembled bolt that Fig. 2 provides for the utility model.
With reference to shown in Figure 1, as can be seen, anchor bar body (1) is to make with bamboo wood, and the one end is dovetail shaped, bonds with double-quick cement volume or resin volume when practical application.Therefore, improved pull-out capacity, the other end is riveted together with rivet clasp iron wire (3) and gusset piece (2).Gusset piece can be made with steel plate.This iron wire rivet clasp is easy to ensure the quality of products, and is simple to operate, rivet clasp intensity height.For avoiding rivet hole to weaken the shearing resistance of bamboo clappers, each rivet hole dislocation is arranged.Be to guarantee the rivet clasp quality, with fixing iron wire (4) bamboo clappers and steel plate are fixedly clamped in many places earlier.At gusset piece one end cover with steel tray (5).The gusset piece head has pin-and-hole, in use, and with making pallet be close to crag in chock (6) the insertion pin-and-hole.The chock of selecting different size for use is to be fit to different drilling depths, and chock is self-locking, can not withdraw from because of roadway surrounding rock stress strengthens.After fixing, chock and pallet are right-angled intersection, have increased the rigidity of gusset piece after the combination.
The utility model is compared with the prior art anchor metal has following advantage:
Reduce cost 50%, saving steel 70% is given full play to the mechanical property of bamboo wood, compares with common bamboo anchoring-bolt and improves anchor force more than 80%. And solved preferably the connecting mode of the anchor pole head of bamboo anchoring-bolt, overcome the bad fixing shortcoming of anchor pole head of traditional independent bamboo anchoring-bolt. Therefore, can large-arealy in the mine, promote the use of.
Claims (2)
1, a kind of steel bamboo assembled bolt, it comprises anchor bar body, pallet, chock, it is characterized in that: anchor pole one end is dovetail shaped, and the other end is connected with gusset piece, head at gusset piece has pin-and-hole, and chock inserts in the pin-and-hole and contacts with the pallet that is enclosed within the gusset piece end.
2, anchor pole according to claim 1 is characterized in that: said connection plate hole is dislocation and arranges.
