Description

Technical Field

[0001] The utility model relates to the technical field of anti-floating anchor rods, in particular to a single-reinforcement anti-floating anchor rod positioning structure. Background Art

[0002] Anti-floating anchor is a structural member set up to resist the upward displacement of the building above it. Traditional underground anti-floating measures mainly adopt anti-floating anchors with multiple third-grade steel as the main reinforcement, and use the friction between the anchor and the underground soil as the main pull-out resistance. Now more and more new anti-floating anchor construction methods are gradually taking shape. Among them, the capsule expansion anti-floating anchor uses a single high-strength steel bar as the main reinforcement, abandoning the traditional method of using the friction between the anchor and the soil as the pull-out resistance. It increases the pull-out resistance by expanding the bottom head, and is also favored for its advantages such as convenient construction and lower cost.

[0003] For the existing anchor structure using a single reinforcement, the thickness of the protective layer is usually strictly required. Therefore, during the construction process, a positioner is used to protect the thickness of the anchor protective layer. According to the requirements of the specifications, since the positioner is directly welded on the main reinforcement, it will affect the stress performance of the main reinforcement. Therefore, the threaded steel bar main reinforcement cannot usually be directly welded with a protective layer positioner; therefore, a threaded connection is used to install the positioner connected to the anchor; but the existing positioner structure is usually fixed and single, and cannot match anchors and anchor holes of different diameters. The matching degree is low and it is inconvenient to flexibly adjust according to construction requirements. Therefore, there is an urgent need for a single-reinforcement anti-floating anchor positioning structure with a structure that can be flexibly adjusted to adapt to anchor holes and anchors of various diameters.

A radially adjustable positioning clamp 2 is arranged in the supporting sleeve 1, wherein two positioning clamps 2 are provided, and the two positioning clamps 2 are symmetrically arranged. By adjusting the spacing between the two positioning clamps 2, the supporting sleeve 1 and anchor rods 3 of different diameters can be fixedly installed, thereby expanding the scope of application of the utility model. The two positioning clamps 2 are used to clamp and connect with the anchor rod 3, which is not only easy to operate and has strong flexibility, but also will not damage the anchor rod 3 body, thereby ensuring that the structural strength of the anchor rod 3 is not affected. A plurality of split positioning plates 6 are arranged on the outside of the supporting sleeve 1 along its circumferential direction, and each positioning plate 6 can be moved and adjusted along the radial direction of the supporting sleeve 1, so as to match and meet the installation and use of the positioning structure in different anchor holes by adjusting the spacing between the positioning plate 6 and the supporting sleeve 1.

[0022] Furthermore, an adjusting screw 4 is threadedly provided on the support sleeve 1, and the positioning clamping plate 2 is rotatably connected to the adjusting screw 4; by rotating the adjusting screw 4, the spacing between the two symmetrically arranged positioning clamping plates 2 can be adjusted, thereby satisfying the fixing operation of anchor rods 3 with different diameters; wherein, the positioning clamping plate 2 is preferably provided with an arc structure to enhance the fit between the anchor rod 3. In addition, a rubber pad 5 is further provided on the opposite end surface of the positioning clamping plate 2 to enhance the tightness of the connection between the positioning clamping plate 2 and the anchor rod 3.

[0023] Furthermore, the positioning plate 6 is an arc-shaped structure, and in the initial state, adjacent positioning plates 6 are in end-to-end contact to form a circular ring structure; the positioning plate 6 is set to an arc-shaped structure, which can better adapt to the anchor hole, and at the same time, through the synchronous adjustment of multiple positioning plates 6, the centering setting of the anchor rod 3 is guaranteed, ensuring that the entire anchor rod 3 is subjected to balanced force subsequently. Among them, a support ring 7 is coaxially arranged on the outside of the support sleeve 1, and the support ring 7 is connected to the support sleeve 1 by spaced connecting blocks 8, and each connecting block 8 is vertically penetrated with an adjustment hole 9; a support rod 10 is arranged on the side of the positioning plate 6 close to the support ring 7, and the end of the support rod 10 away from the positioning plate 6 movably passes through the support ring 7 and is located in the adjustment hole 9; a driving block 11 which can be adjusted in the vertical direction is arranged on the support sleeve 1, wherein the end of the driving block 11 opposite to the support rod 10 is an inclined surface, and in the initial state, the inclined surface at the end of the support rod 10 partially overlaps with the inclined surface on the driving block 11, and during operation, as the driving block 11 continuously moves into the adjustment hole 9, the support rod 10 will be pushed out and drive the positioning plate 6 to move outward, thereby realizing the adjustment operation of the positioning plate 6.

[0024] A positioning sleeve 12 is arranged above the support sleeve 1, and the number of the positioning sleeves 12 matches the number of the positioning plates 6. A positioning rod 13 is arranged at the top of the driving block 11, and the positioning rod 13 is movably located in the positioning sleeve 12, and the top end passes through the positioning sleeve 12. A deformable positioning tooth 14 is arranged on the positioning rod 13, so that by pressing the positioning rod 13, the positioning tooth 14 can be moved out of the positioning groove 15, and as the positioning rod 13 is continuously moved downward, the positioning tooth 14 is engaged and positioned in different positioning grooves 15, thereby meeting the purpose of vertical adjustment and positioning of the driving block 11. ; Among them, the positioning groove 15 is arranged on the positioning sleeve 12, and the positioning groove 15 and the positioning teeth 14 are arranged in plurality to enhance the stability of the driving block 11; since the diameter of the anchor hole varies with the anchor rod 3, and the diameter difference of different anchor holes is not too large, and the diameters of different anchor holes are generally universal fixed data, the distance between the positioning teeth 14 can be set according to the minimum diameter difference between the anchor rods 3 or the anchor holes as a unit, so that the positioning teeth 14 correspond to the anchor rods 3 or anchor holes of different diameters in different positioning grooves 15, thereby improving the accuracy of adjusting the positioning plate 6.
