Description

A kind of device improving anchor pole resistance to plucking effect
Technical field
The utility model belongs to building engineering field, particularly relates to a kind of device improving anchor pole resistance to plucking effect.
Background technology
anchor polebe widely used in construction project.Bolt support is a kind of its support reinforcement mode adopted in the constructions such as earth's surface engineering and tunnel such as side slope, ground deep foundation ditch.
Bolt support is the hole being drilled to bolt diameter with rig and deeply crossing, then anchor rod component is inserted in hole, by anchor sprayed concrete, anchor pole and country rock are formed a bearing structure jointly, effectively can limit the Free Development of surrouding rock deformation, the stress distribution of adjustment country rock, prevents that rock mass is loose to fall., because the anchor structure used now is fairly simple, 3 ~ 4 meters even anchor pole of 5 ~ 6 meters long contact with rock mass without any device, and can only lean on concrete perfusion that anchor pole is connected consolidation with rock mass, consolidation effect is bad.In construction, only have by dense bolt quantity, increase the length of anchor pole, the carrying of anchor pole and country rock consolidation just can be made to reach optimum efficiency.
Utility model content
The purpose of this utility model is to provide a kind of device improving anchor pole resistance to plucking effect, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model have employed following technical scheme:
A kind of device improving anchor pole resistance to plucking effect, comprise anchor rod component and resistance to plucking assembly, anchor rod component comprises bolt body, anchor pole head, stop grouting plug and nut, bolt body is screw rod, anchor pole head is positioned at the end of bolt body side, the end of bolt body opposite side is flexibly connected with nut through stop grouting plug, and stop grouting plug is fixedly connected with nut; Resistance to plucking assembly comprises adjustable nut and retaining pawl, and adjustable nut is fixedly connected with retaining pawl, and adjustable nut and retaining pawl are in bolt body and be between anchor pole head and stop grouting plug.
Preferably, retaining pawl material is iron and steel.
Preferably, retaining pawl and adjustable nut are by being welded and fixed.
Preferably, retaining pawl comprises three calvus.
Preferably, the corner dimension of plane residing for calvus and bolt body axis is 30 degree.
Compared with prior art, the beneficial effects of the utility model are as follows:
The utility model is in use according to the position of rock mass conditions adjusting nut in bolt body, when bolt body forward inserts in rock mass, due to the retaining pawl effect of opening, retaining pawl contacts with rock mass and can not retreat, add the contact of rock mass and anchor pole, anchor pole and rock mass contact stabilization, therefore, the utility model improves the uplift resistance of anchor pole, makes its support reinforcement better effects if of anchor pole.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device improving anchor pole resistance to plucking effect.
Detailed description of the invention
Below in conjunction with embodiment, preferred embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of device improving anchor pole resistance to plucking effect, comprise anchor rod component and resistance to plucking assembly, anchor rod component comprises bolt body 1, anchor pole head 2, stop grouting plug 3 and nut 4, bolt body 1 is screw rod, anchor pole head 2 is positioned at the end of bolt body 1 side, and the end of bolt body 1 opposite side is flexibly connected with nut 4 through stop grouting plug 3, and stop grouting plug 3 is fixedly connected with nut 4; Resistance to plucking assembly comprises adjustable nut 5 and retaining pawl 6, and adjustable nut 5 is fixedly connected with retaining pawl 6, and adjustable nut 5 and retaining pawl 6 are in bolt body 1 and be between anchor pole head 2 and stop grouting plug 3.
In order to further optimisation technique scheme, retaining pawl 6 material is iron and steel.Retaining pawl 6 and adjustable nut 5 are by being welded and fixed.Retaining pawl 6 comprises three calvus.The corner dimension of plane residing for calvus and bolt body 1 axis is 30 degree.
The utility model on the basis of existing technology, bolt body 1 increases the retaining sheet 6 of one group of adjustable moving formula, retaining sheet 6 comprises three calvus be welded on adjustable nut 3, in use according to the position of rock mass conditions adjusting nut 4 in bolt body, when bolt body 1 forward inserts in rock mass, because the retaining pawl 6 opened acts on, retaining pawl 6 contacts with rock mass and can not retreat, add the contact of rock mass and anchor pole, anchor pole and rock mass contact stabilization.
Illustrate in addition, if rock mass country rock loosely, broken, suitably can increase the number of components that adjustable nut 5 and retaining pawl 6 form and can reach desirable its support reinforcement effect.
The utility model can strengthen anchor pole and arrange, reduces usage quantity and the rock-bolt length of anchor pole, reduces artificial, material cost, improve speed of application.Make simple, easy and simple to handle, safe and reliable, economical and practical, can be in large-scale application.
Above embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
