Description
Technical field
The utility model relates to the realm of building construction, particularly a kind of anchor pole orienting locator.
Background technology
Conventional anchor, be the most basic ingredient of the roadway support in the middle of mine, it by the surrounding rock consolidation in tunnel together.Present anchor pole is not only for opening a mine, and also in engineering, reinforce deep foundation ditch resistance to plucking earth anchor, the underground constructions such as side slope, tunnel, underground rail traffic carry out active enforcement process.
Anchor pole composition must possess several factor: 1, tensile strength is higher than the anchor rod body of the frictional force of Rock And Soil own; 2, anchor rod body bottom can form frictional resistance with Rock And Soil close contact; 3, anchor rod body be positioned at the top of Rock And Soil outside can the Radial resistant force of Rock And Soil in pairs.
Anchor pole is as the tensional element going deep into stratum, and top is connected with engineering structure, and bottom is goed deep in stratum, and whole anchor pole is divided into free segment and anchoring section, and free segment refers to and the pulling force at anchor pole head place is reached anchorage zone, and its function is to anchor pole Shi Hanzhang; Anchoring section refers to that the region that presstressed reinforcing steel and soil layer bond by cement slurry, its function are increased at the bonding rubbing action of anchoring body and soil layer, increases the pressure-bearing effect of anchoring body, the pulling force of free segment is reached soil body depths.
The body of rod of anchor pole can be the material that reinforcing bar, steel pipe and tensile strength are higher, and the construction technology of anchor pole is all generally first hole, then anchor rod body is put into boring, then slip casting; Also can drilling holes and late grouting, then anchor rod body is put into boring, after anchor rod body puts into boring, how to guarantee that anchor rod body is positioned at the middle position of boring, avoiding the body of rod directly to abut on borehole wall, is very important.In the middle of some underground constructions, for soft foundation, also need to adopt mortar grouting method, thus to Soil Anchor Design, anchor pole device and be manufactured with particular/special requirement.
Utility model content
In order to overcome above-mentioned technical problem, the purpose of this utility model is the anchor pole orienting locator providing a kind of accurate positioning, easy construction.
The technical scheme that the utility model adopts is:
A kind of anchor pole orienting locator, comprise outer sleeve and self-locking block, be provided with anchor pole in described outer sleeve vertically and penetrate hole, described self-locking block is arranged in outer sleeve, the wall that inner face and the anchor pole of described self-locking block penetrate hole is roughly concordant, the outer face of described self-locking block and outer sleeve inwall compact siro spinning technology.
As further improvement of the utility model, described self-locking block is the elastic wedge block that bottom is wide, top is sharp, and described self-locking block inserts bottom outer sleeve.
As further improvement of the utility model, the outer face of described self-locking block and the inwall of outer sleeve are the zigzag mutually engaged.
As further improvement of the utility model, it is female thread structure that described anchor pole penetrates hole.
As further improvement of the utility model, the outer wall of described outer sleeve is provided with Grouting Pipe preformed hole, and described Grouting Pipe preformed hole axially extends along outer sleeve.
As further improvement of the utility model, described outer sleeve is provided with iron wire colligation preformed hole, and described iron wire colligation preformed hole is positioned at the both sides of Grouting Pipe preformed hole.
As further improvement of the utility model, described outer sleeve is made of plastics.
The beneficial effects of the utility model are: the utility model puts into boring after being placed on anchor pole periphery by outer sleeve again, be positioned in the middle part of outer sleeve by self-locking block by anchor pole, and outer sleeve and the wall of boring are contacted with and are coordinated, so anchor rod body just must be positioned at the middle position of boring, its accurate positioning, convenient construction, improves the efficiency of construction.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is upward view of the present utility model;
Fig. 3 is the connection diagram of self-locking block.
Detailed description of the invention
Anchor pole orienting locator as shown in Figure 1 to Figure 3, comprises outer sleeve 1 and self-locking block 2.It is round table-like that outer sleeve 1 is that base diameter is large, top diameter is little, and it is made of plastics, and plastics have certain elasticity, facilitates outer sleeve 1 to enter in boring.Be provided with anchor pole in the middle part of outer sleeve 1 vertically and penetrate hole 3, being inserted in for anchor pole.Self-locking block 2 is arranged in outer sleeve 1, and the wall that inner face and the anchor pole of self-locking block 2 penetrate hole 3 is roughly concordant, the outer face of self-locking block 2 and outer sleeve 1 inwall compact siro spinning technology.When outer sleeve 1 is enclosed within anchor pole periphery, the inner face of self-locking block 2 fits tightly anchor pole outer wall, and outer face compact siro spinning technology outer sleeve 1 inwall of self-locking block 2, therefore effectively can place anchor pole relative to the axis of outer sleeve 1 and axial displacement.
Preferably, self-locking block 2 is the elastic wedge block that bottom is wide, top is sharp, and the bottom of outer sleeve 1 is provided with preformed hole 6, and self-locking block 2 inserts from preformed hole 6.Self-locking block 2 needs to have elasticity, its reason it is being squeezed into by external force after in preformed hole 6 and certain compressive deformation can occur, make the end face of both sides respectively with producing very large frictional force between anchor pole 7 and outer sleeve 1, thus make the stable position of anchor pole 7 and outer sleeve 1.Therefore, self-locking block 2 can be made of plastics.
In order to better realize the function of self-locking, the outer face of self-locking block 2 and the inwall of outer sleeve 1 are the zigzag mutually engaged, and self-locking block 2 after entering, can not be exited by the connection of sawtooth, as shown in Figure 3 easily.
Meanwhile, in order to better prevent the axial location of anchor pole 7 and outer sleeve 1, anchor pole penetrates hole 3 for female thread structure, and now anchor pole can make external thread structure in advance.
By above-mentioned structure, when reality uses, first outer sleeve 1 is enclosed within outside anchor pole, adopts self-locking block 2 to connect afterwards, entirety is inserted in the boring of slip casting in advance.So, outer sleeve 1 outer wall and drill hole wall are fitted, and therefore anchor pole can be accurately positioned in boring central authorities.
In another preferred embodiment, as depicted in figs. 1 and 2, the outer wall of outer sleeve 1 is provided with Grouting Pipe preformed hole 4, and Grouting Pipe preformed hole 4 axially extends along outer sleeve 1.Outer sleeve 1 is also provided with iron wire colligation preformed hole 5, iron wire colligation preformed hole 5 is positioned at the both sides of Grouting Pipe preformed hole 4.
Outer sleeve 1, when reality uses, is first enclosed within outside anchor pole by this embodiment, adopts self-locking block 2 to connect afterwards; Grouting Pipe is put into Grouting Pipe preformed hole 4, and by the iron wire penetrating iron wire colligation preformed hole 5, Grouting Pipe colligation is fixed; Last entirety is put into after boring by Grouting Pipe slip casting.
The above be the utility model preferred embodiment, it does not form the restriction to the utility model protection domain.
