Description
Technical field
The invention belongs to anchoring device technical field, relate to the outer anchor of a kind of nonmetal anti-float anchor rod, the device that particularly a kind of nonmetal anti-float anchor rod anchors with reinforced concrete floor, foundation adopts the technology of anti-float anchor rod opposing buoyancy force of underground water, solves the anchorage problem of nonmetal anti-float anchor rod and reinforced concrete floor.
Background technology:
The advantages such as it is strong that anti-float anchor rod has ground adaptability, dispersive stress, it is simple to construction, saving construction cost, especially in hard rock soil layer, bearing capacity is big, more advantage. the existing anti-float anchor rod body of rod adopts metal material mostly, after the rock mass soil layer that its embedment is stable, continuity over time, rod body material easily corrodes, affect anchor bar body intensity, and then its anchoring effect is damaged, this phenomenon is especially prominent in the anti-floating on coastal area buildings or structures basis. in the Construction of Urban Rail Traffic such as subway, DC power-supply system the stray electrical current produced, metal material is produced electrochemical corrosion also comparatively serious. therefore, anchor pole Anticorrosion Problems in the earth formation does not fundamentally solve. so when being impermissible for adopting anchor metal, using nonmetallic materials GFRP anchor pole to become optimum selection. under normal circumstances, regular reinforcement anchor pole aperture section reinforcing bar anchors after directly bending in girt strip, for GFRP muscle, its anti-bending strength is not good, bending anchoring can not be carried out at the construction field (site) as reinforced anchor bolt, and the shearing strength of GFRP anchor pole is also far below its tensile strength, according to common strand tapered anchorage, in anchorage zone, fiber bar is produced excessive chucking power, cause the failure by shear of fiber bar, this causes very big difficulty to the outer anchoring (anchoring with reinforced concrete floor) of GFRP anti-float anchor rod, therefore anchor head adopts the anchoring process of regular reinforcement anchor pole. simultaneously as underground structure bottom plate finite thickness, GFRP anchor pole directly anchors in base plate, in fact it could happen that anchorage length is not enough, does not reach predetermined anchoring effect. therefore, seek to design the outer anchor of a kind of nonmetal anti-float anchor rod to be of great practical significance to solve the weak point of anchoring outside GFPR anti-float anchor rod.
Summary of the invention:
It is an object of the invention to the shortcoming overcoming prior art to exist, seeking design provides the outer anchor of nonmetal anti-float anchor rod that a kind of corrosion resistance is good, have enough anchor force, solves an outer anchoring difficult problem for puzzlement engineering circles.
To achieve these goals, the agent structure of the outer anchor of nonmetal anti-float anchor rod of the present invention includes anchor rod body, localizer, steel pile casting, angle bar, steel plate for sealing water, bed course, cement mortar, reinforced concrete floor and Rock And Soil; The anchor rod body of full thread solid construction adopts glass fiber compound material (GFRP) to make, to improve the cohesion between anchor rod body and anchoring body, thus providing enough anchoring frictional force, anchor rod body is made up of grouted part and outer anchoring section two parts, anchor rod body anchoring section inner bending outside is at a right angle, 3-5 times that radius is anchor rod body diameter of arc place, bending place circle; Outer anchoring section is provided with localizer, and localizer is connected with anchor rod body and steel pile casting respectively, plays centering effect when anchor rod body is installed, and makes anchor rod body have enough protective layers; Equipped with steel pile casting outside outer anchoring section, steel pile casting, the outer anchoring section of anchor rod body and localizer adopt cement mortar tight bond; Angle bar is welded on the outer wall bottom steel pile casting, and steel pile casting and angle bar are fixed on Rock And Soil all in a welding manner; Bed course is laid on Rock And Soil, and bed course is connected with grouted part, outer anchoring section respectively; The lateral wall of steel pile casting is welded with steel plate for sealing water, the closely coupled formation integral structure of outer anchoring section of steel pile casting and steel plate for sealing water and anchor rod body, the integral structure of the outer anchoring section composition of steel pile casting, steel plate for sealing water and anchor rod body is built in reinforced concrete floor, it is provided that reach the purpose of waterproof while continuing anchor force.
It is M30 or M32.5 as the strength grade of described cement mortar of the present invention.
Steel pile casting of the present invention is the seamless steel pipe of diameter 146mm, wall thickness 8mm, the outer wall of steel pile casting respectively with reinforced concrete floor and bed course tight bond, inwall and cement mortar tight bond, steel pile casting is arranged on the outer anchoring section of anti-float anchor rod can not only quickly form anti-floating anchor force, moreover it is possible to ensure that anti-float anchor rod is not cut up by horizontal force.
The specifications and models of angle bar of the present invention are 40mm �� 40mm �� 3mm, and length is 30cm, is fixed on bed course by steel pile casting.
Steel plate for sealing water of the present invention adopts thickness to be 4mm, diameter is the circular steel plate of 450mm to make, and middle reserved aperture is the hole of 150mm, closely coupled with the outer wall of steel pile casting by the mode welded, and forms entirety with outer anchoring section, reaches waterproof purpose.
Bed course of the present invention, between grouted part and outer anchoring section, is made up of the C15 plain concrete that thickness is 100mm, plays water proof, draining, antifreeze and improve the effect of anti-float anchor rod working condition.
The present invention realizes the detailed process of anchoring outside nonmetal anti-float anchor rod:
(1), by steel plate for sealing water being inserted in steel pile casting and adopt the mode firm welding of two-sided welding, welding position is positioned at the centre of outer anchoring section, at two-sided all brushing antirust paints of steel pile casting outer wall and steel plate for sealing water after welding;
(2), the steel pile casting with steel plate for sealing water is pre-installed on outer anchoring section, when the grouted part of anchor rod body is constructed, the reserved 10cm in the top of grouted part is used for installing steel pile casting, localizer is arranged on the outer surface of anchor rod body and is located at outer anchoring section, anchor rod body traverse steel pile casting, adjusting the position of localizer again, make localizer be positioned at 5cm place below steel pile casting end face, grouted part has been constructed rear maintenance 28 days;
(3) the reinforced concrete floor lower end, bottom steel pile casting is symmetrically welded two angle bar, during welding, steel pile casting is lifted up 5mm, and Rock And Soil is close to by angle bar, makes angle bar be secured firmly on Rock And Soil by steel pile casting;
