Description

Rigidity anchoring trees dead lever

Technical field

The utility model relates to a kind of rigidity anchoring trees dead lever, is used for greening the fixing of wood of newly planting trees, and guaranteeing not increases the survival rate of the wood of newly planting trees because wind or factor such as artificial cause the wood of newly planting trees crooked or topple over.

Background technology

Trees are fixing greatly to fixedly dual mode of rigid pile support and flexible anchor is arranged at present.(1) rigid pile supports according to the trees size and divides single pile, two, three, four again, and support concept is the same substantially, present four usefulness more.Four supports of rigidity are to come to the tree bar with four quarter butts earlier, intersect at certain altitude to be bundled into a square joint, then four intersections are bundled on this four directions joint, and footing support ground is finished the rigid support of trees is fixed.Characteristics are: rigid pile has certain rigid and intensity, and this supporting way makes rigid pile can only bear axial compressive force and radial load and do not bear axial tension that radial load belongs to the power of scratching has destructiveness to stake.When a pair of stake of external force direction and certain supporting surface direction is consistent, namely during the poorest a kind of stressing conditions, has only the single-pile stress of contrary external force direction, because stake is to intersect to tie on the joint of four directions, so this stake both had been subjected to axial compressive force also to be subjected to radial load, all the other stakes all do not stress, and are namely inoperative.Being subjected to external force to disturb most applications is two bar pressurizeds, and two bars are inoperative.For this reason, single pile must have enough rigidity and intensity, and namely the single pile radial dimension wants big, just can reach good fixed effect, causes the Master Cost height.In addition, the four directions joint is difficult for binding, four quarter butts and tree bar lean on too tight easily injury bark, growth and the survival rate of influence tree, it is poor to lean on loosely fixed effect, and between quarter butt and quarter butt, all to intersect binding between quarter butt and stake, time-consuming and difficulty is also big, need there be the skilled worker of certain qualification just can finish the labour cost height.In sum, rigid pile supports that expense expect, taken a lot of work, difficulty is big, but owing to support effect is good, also is comparatively traditional a kind of trees fixed form, so at present still in extensive use.(2) fixing single anchor, two anchors, three anchors, four anchors of also dividing of flexible anchoring, the same substantially to the fixation principle of trees, it is more that present four anchors are used.Flexible four anchorings are to set centered by the bar surely, leaving uniform four stakes that have certain-length to make with wooden or other material on the tree bar certain distance circumference, this is dark slotting underground as anchor, fix a joint at tree bar certain altitude, with flexible material such as steel wire or the tight connection of rope (to call anchor line in the following text), finish fixing trees between joint and the anchor.Characteristics are: anchor line does not have any rigidity, can only be subjected to pulling force, when a pair of anchor line direction of external force direction and certain consistent, namely during the poorest a kind of stressing conditions, have only anchor line of suitable external force direction to be subjected to pulling force, and this pulling force has only the single anchor with its connection to bear, and its excess-three anchor and anchor line all do not stress, and be namely inoperative.Being subjected to external force to disturb most applications is two anchors and anchor line tension, and all the other two anchors and anchor line are inoperative.For this reason, single anchor line must have enough tensile strengths, and especially single anchor must can bear enough big power, just can reach good fixed effect.The stake of Master Cost relative stiffness is supported lower, but the making of joint is fixed, the suitable tension of anchor line, bigger as the difficulty such as stake making of anchor, the labour cost height.In sum, flexible anchoring fixedly material-saving, take a lot of work, difficulty is big, most critical spare anchoring pile mostly is field fabrication simultaneously, be subjected to the instrument condition restriction, of poor quality, insert dark not enough, cause the fixedly weak effect of trees of flexible anchoring, so the present less employing of flexible anchoring fixed form.

Summary of the invention

The purpose of this utility model provides a kind of rigidity anchoring trees dead lever; solve that present trees fixed form expense is expected, taken a lot of work, efficient is low; fixed mass instability to trees; the materials disunity; binding mode defective complicated and that easily bark is damaged, with save, simple and easy to do, high efficiency, steady quality are reliable, have the mode of fine protection that trees are fixed to bark.

The purpose of this utility model realizes as follows: this rigidity anchoring trees dead lever, comprise a rigid rod, the rigid rod two ends are by the hinged hinged-support of bearing pin difference, some connecting holes are set on the plane of hinged-support end, the flanging that turns on the both sides, plane of hinged-support end have forms end slot, be covered with soft pad on the hinged-support end plane of top, bottom hinged-support end plane fixedly has anchoring pile.

There is penetrating fixing hole the side of hinged-support.

During use, the hinged-support of soft pad will be arranged in the binding of tree bar certain altitude firmly, look end slot that concrete condition can select hinged-support also optional fixing hole bundle, it is stable then anchoring pile and rigid rod to be kept plumbness to insert underground anchoring, this moment, the rigid rod nature formed an angle with the tree rod, can finish rigidity anchoring trees dead lever fixing trees.Looking concrete condition in the use can select two bars, three bars, four pole pair trees to carry out the rigidity anchored, general four bars that use are more, below with four-bar the advantage of rigidity anchoring trees dead lever is analyzed: the axial tension of rigid rod, compression strength are bigger, and anti-radial load intensity is less.The power of radially scratching during the rigid rod tension is little to its influence, can be considered best stress.Radially to scratch its compression strength of power not bigger if having during the rigid rod pressurized, can be considered better stress.If there is its compression strength of the power of radially scratching to reduce greatly, can be considered relatively poor stress during the rigid rod pressurized.Its anti-radial load intensity is less during the rigid rod radial force, can be considered the poorest stress.When anchoring pile and rigid rod were in plumbness in addition, the stress of anchoring pile pressurized, tension was basic the same.The poorest a kind of stressing conditions of four-bar rigidity anchored trees is that external force direction is when consistent with certain a pair of rigid rod supporting surface direction, contrary external force direction one side rigid rod is subjected to axial compressive force, anchoring pile is directed downwards along rigid rod and is subjected to same pressure, because the rigid rod two ends are for being hinged, make it not be subjected to radially to scratch power, rigid rod is in better stress.Be subjected to axial tension along external force direction one side rigid rod, anchoring pile upwards is subjected to same pulling force along the rigid rod direction, and same because the rigid rod two ends for being hinged, make it not be subjected to radially to scratch power, rigid rod is in best stress.A pair of rigid rod supporting surface is vertical with external force direction stressed less in addition, can be considered inoperative.Disturbed by external force, in most cases have two rigid rods to be in and be subjected to state of tension, two other rigid rod is in the state of being stressed, and same anchoring pile also has two be stressed by pulling force, two.In a word, because the rigid rod two ends are for being hinged, avoided being subjected to radially scratching power, made rigid rod be in the good tension state that is stressed all the time.The more above-mentioned stressed bar that works of two kinds of trees fixed forms while of rigidity anchoring trees fixed form and anchor double.For this reason, the radial dimension of rigidity anchoring trees dead lever can reduce more than one times than rigid pile support bar radial dimension, and the reliability of anchoring pile anchoring doubles many than the reliability of flexible anchoring anchoring pile.Need not joint, only need will be in tree bar certain altitude upper edge circumferentially uniform four hinged-supports bindings together or twice connect firmly with the tree bar, then four anchoring piles edge directions vertical with rigid rod are inserted that underground anchoring is stable to get final product.The binding point is few, does not have the binding of intersection, and it is easy to operate to save time, and the soft pad of built-in protection bark does not have any injury to bark.

The utility model can realize that the fixing material of trees saves, reusable repeatedly, and rigid rod bar footpath can reduce; Fixed form is simple, and operating efficiency improves greatly, can finish in two people 3-5 minutes, and current mode two people need 15-20 minute; Fundamentally stopped trees injury to bark fixedly the time; But professional production can realize the fixing unification of trees, purpose such as attractive in appearance, stable, and is easy to utilize.
