Technical field

The present invention relates to limiting device, in particular to a kind of anchor pole limiting device.

Background technique

Side slope and foundation pit protection mostly uses Anchored frame beam, anchor pole shotcrete with steel bar nets etc. protect, anchor pole be in slope reinforcement most A kind of cost-effective mode has the advantages that good supporting effect, easy to operate, using flexible, occupancy construction space are few, makees It is anchor pole one end along the rock mass stability within the hole insertion slope sliding face being drilled with principle, the other end and slope surface are with outline border Equal safeguard structures object of setting a roof beam in place connects, and reinforces the cohesive force of anchor pole and rock mass by filling the water cement mortar into hole to resist the cunning of slopes Power.The adhesion strength of anchor pole and rock mass is critically depend on the mortar turgor around anchor pole, mainly adopts in industry at present The triangle limit rib made of HPB300 φ 6,10 reinforcement welding of φ fixes anchor pole.On the one hand, this method low efficiency expends people Power；On the other hand, after the soldered anchor pole insertion drilling of limit rib, since limit rib is very thin, along in anchor pole gravity work Under, limit rib is easy to be pressed into the soil body, is especially easier to be pressed into the soil body in soft rock stratum, so that anchor pole and drilling hole Wall rock stratum contact side injection mortar is not full, influences anchor pole protection effect, leaves security risk to follow-up work.

Summary of the invention

It is an object of the invention to overcome the deficiencies of the prior art and provide one kind may be implemented quickly to connect with anchor pole, mention High construction efficiency；And anchor pole can be allowed to be always positioned at drill center, guarantee the anchor pole limiting device of subsequent slip casting plumpness.

A kind of anchor pole limiting device of the invention, including fixing the main body constituted by the identical two halfbodies docking of structure, The main body includes intermediate, is connected in turn in the top and bottom of the intermediate and is coaxially set with intermediate Buckle closure, the intermediate is circle ring column shape structure, and the intermediate includes upper and lower two circumferential limit steel plates, in institute Uniform intervals are connected with multiple longitudinal spacing steel plates along the vertical direction between the two circumferential limit steel plates up and down stated；

The buckle closure is funnel-shaped structure, and the funnel-shaped structure includes annulus taper type neck and bores with annulus The connected annulus cylindricality end of platform shape neck, the diameter big end of the annulus taper type neck limit steel plate with corresponding circumferential direction It is fixedly linked, 180 degree is spaced on the wall surface of the annulus taper type neck and is opened there are two trapezoidal hole, the annulus cylindricality The internal diameter of end is consistent with bolt diameter to be passed through, and two semicircular ring cylindricality ends that docking constitutes annulus cylindricality end pass through Circumferentially hose clamp of the cuff on two semicircular ring cylindricality ends fixes together.

The present invention compared with existing invention, present invention has the advantage that

It may be implemented quickly to connect with anchor pole using the present apparatus, increase substantially limiter installation efficiency；Other one The longitudinal spacing steel plate of fixed width degree and circumferential limit steel plate make anchor pole become larger with institute drill hole inner wall contact area, it is not easy to fall into In rock stratum, so that anchor pole is always positioned at drill center, subsequent slip casting plumpness ensure that.

Specific embodiment:

The invention patent is described in detail in the following with reference to the drawings and specific embodiments.

A kind of anchor pole limiting device of the invention as shown in drawings, including fixed by the identical two halfbodies docking of structure The main body of composition, the main body include intermediate 2, are connected in turn and centre in the top and bottom of the intermediate The buckle closure 1 that body is coaxially set, the intermediate are circle ring column shape structure, and the intermediate includes upper and lower two circumferential directions Steel plate 5 is limited, uniform intervals are connected with multiple longitudinal limits along the vertical direction between two circumferential limit steel plates 5 up and down Position steel plate 6, the number of preferred longitudinal spacing steel plate are four, become anchor pole and institute's drill hole inner wall contact area Greatly, it and avoids increasing cost.

The buckle closure 1 is funnel-shaped structure, and the funnel-shaped structure includes annulus taper type neck and and annulus The connected annulus cylindricality end of taper type neck, the diameter big end of the annulus taper type neck limit steel with corresponding circumferential direction Plate 5 is fixedly linked, and 180 degree is spaced on the wall surface of the annulus taper type neck and is opened there are two trapezoidal hole, the annulus The internal diameter of cylindricality end is consistent with bolt diameter to be passed through.

Two semicircular ring cylindricality ends of docking composition annulus cylindricality end are by circumferentially cuff in two semicircle annulated columns Hose clamp 3 on shape end fixes together.

Working principle: two halfbody alignment are closed up and anchor pole 4 are allowed to pass through buckle closure 1 by setting position on anchor pole 4, then are used Hose clamp 3 is lockked in the annulus cylindricality end point circumferential direction of buckle closure 1, the fixation of anchor pole 4 and limiting device is completed, similarly, on anchor pole 4 One fixed spacing completes another limiting device installation, until an anchor pole position limit device is all installed.It is existing compared to industry Welded limiting reinforcing bar, increases substantially construction efficiency；In addition, there is one fixed width, strong on anchor pole limiting device after being installed The four longitudinal spacing steel plates 6 and two circumferential limit steel plates 5 of degree and rigidity, so that anchor pole and institute's drill hole inner wall contact area become Greatly, anchor pole 4 is always positioned at drill center, ensure that subsequent slip casting plumpness.
