The present invention relates to removal expression acceptor for the anchor, the anchor structure and expression removed Removable anchor removal process that can be dismantled after the strand construction.
The invention of the cylindrical body portion to resolve the above problems; Insertion grooves formed in the axial direction in the central portion of the body top surface portion; Thread groove formed in a hexagonal bottom surface in the central portion of the body portion; As the ring-shape surrounding the screw hole in the lower end face, the inner diameter is greater than the cutting diameter of the body portion recess; Upper flange formed on the upper end outer periphery; Long wrote that the stop flange formed in the body portion stop the radius than the top flange; It wrote that formed in the lower end of the outer periphery, a long radius than the stop flange and the outer flange at the bottom of this thread is formed on the periphery; As it is configured to include an acceptor provides for removal expression anchor is fabricated by reinforced plastic materials.
The present invention also Strand; Coated pipe; connector; Wejji; Paragraph 1 acceptor; Combined pipe; And a cover cap, in the removal expression anchor the tip structure to a sequential coupling in the axial direction, wherein the connector and the through hole in the center is formed, one end is coupled to the end portion and the axial direction of the coated pipe, the outer periphery of the other end coupled and the coupling projection is formed to be coupled with the pipe, the inner peripheral surface is an inner conically converging is formed to be connected with said through hole, wherein the strand is to be through the aperture protrudes acceptor the control of the connector is pulled out from the covering pipe is inserted, the hardware is combined conical inner circumferential surface and brought into close contact with the strands of steaming the connector as fixing ask to hold the strand, said there my be a fitting groove formed circumferentially on the periphery've done a top flange and fitting of the susceptor is, the outer being the end that is the departure avoidance groove formed along the circumference on the peripheral over sandwiched between the word at the top of the susceptor flange and the stop flange, the coupling pipe has one end coupled to the coupling projection of the connector and the other end of the cover cap and a cylindrical opening that is coupled, wherein it is threaded is formed in the inner peripheral insert groove bottom flange outer engaged with the thread of the periphery of the strand according to the rotational direction of the fixed combination Strand the wejji and as acceptor integral with and acceptor before and after the movement and the cover cap there is provided a structure in which the tip anchor removal formula is coupled to an end of the coupling pipe configuration, including formed to prevent insertion of foreign objects.
In addition, the present invention provides a method for removing the removal expression anchor by claim 2 the tip structure after construction earth anchor, (a) the control to rotate the fixed strand inserted into the susceptor above the strand, wejji and acceptor cover cap direction moving in; (B) separation step is also in close contact with the portion of the strand as a disconnect wejji were combined in close contact with the connector; Provides a way to remove the anchor removal process is configured including; (c) withdrawing the coated strand in the pipe direction.
