Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a positioning method and a simple positioning tool for inclined piles. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Currently, the conventional inclined pile construction process in building engineering involves leveling the ground to the designed pile top elevation, erecting an inclined guide frame, tilting the pipe pile into position, and then driving the pile using a hammer or static pressure equipment. This process has the following problems: 1. Before construction, each pile requires the erection of an inclined guide frame and manual adjustment of the pipe pile angle, which is time-consuming and slows down the construction efficiency. 2. Before construction, the ground must be leveled to the designed elevation. If the soil bearing capacity at the designed elevation is insufficient, foundation treatment is also required, which is also time-consuming.

[0004] In the current conventional inclined pile construction process in domestic building engineering, if there is a height difference between the construction ground elevation and the design pile top elevation, it is necessary to measure the original ground elevation of each pile position on site, and then calculate the actual pile entry position by using the height difference and the inclined pile angle. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings by providing a positioning method and a simple positioning tool for inclined piles.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a positioning method, specifically including the following steps: S1. Surveying and mapping stage: By measuring and setting out, the center diameter lines at the top elevation of multiple design pile positions are laid out. Then, the elevation of the construction site and the top elevation of each design pile position are measured using measuring instruments. S2. Calculation stage: Apply the principle of trigonometric functions to calculate the horizontal distance deviation corresponding to different elevations of the construction site; S3. Production stage: Construct a frame, set a reference main rod at one end of the frame, and set multiple positioning rods at intervals on the frame. The distance between each positioning rod and the reference main rod is equal to the value of the deviation of each horizontal distance. S4. Usage Stage: Align the center of the reference main rod with the top elevation of the designed pile position, measure the elevation of the construction site, and find the positioning rod corresponding to the elevation on a frame based on the elevation to locate the actual construction pile entry point.

It includes a reference main rod set at the bottom of the two side rods and two reference secondary rods slidably set on the reference main rod. The reference secondary rods are fixedly connected to the corresponding side rods and drive the side rods to move relative to the reference main rods to adjust the distance between the two side rods. A first verification hole is provided at the center point of the corresponding designed pile position on the main reference rod, and a second verification hole is provided at both ends of the center line of the corresponding designed pile position on the two secondary reference rods. The intermediate positioning assembly includes a plurality of positioning rods disposed between the two side rods and arranged along the length of the side rods. Each positioning rod has a connecting unit a at both ends, and the connecting unit a is used to detachably fix the positioning rod at a corresponding position on the side rod.

[0008] Furthermore, the reference main rod is provided with an adjustment mechanism, which is used to drive and adjust the spacing of the side rods fixed on the reference secondary rods distributed at both ends; The adjustment mechanism includes a rotating block rotatably disposed at the center of the upper end of the reference main rod, and a lead screw b passing through the rotating block. The lead screw b is provided with two threaded parts that are symmetrical to the left and right and rotate in opposite directions. A support vertical plate is provided at the upper end of the reference auxiliary rod near the center of the reference main rod. The support vertical plate is adapted to be rotatably connected to the threaded parts.

[0009] Furthermore, the positioning rod consists of a hollow tube and two movable rods. The hollow tube has openings a at both ends, and the adjacent ends of the two movable rods are slidably inserted into the openings a and connected inside the hollow tube by an elastic rope.

[0010] Furthermore, the connecting unit a includes a fixed block disposed on the movable rod corresponding to the end of the side rod, a magnetic block disposed on the outer end of the fixed block and moving along the length direction of the movable rod, and a vertically movable support side block disposed on one side facing each other on the two side rods. An opening b is disposed on the support side block corresponding to the end of the movable rod, and a metal plate that cooperates with the magnetic block is disposed on the inner end of the opening b.

[0011] Furthermore, sleeves are provided through the end faces of both support side blocks, one sleeve is fitted with a lead screw a, which is rotatably mounted on the end face of the corresponding side rod, and the other sleeve is fitted with a guide rod, which is fixedly mounted on the end face of the corresponding side rod. A limiting plate is provided at the bottom end of the sleeve, which is used to support the supporting side block and prevent it from moving on the sleeve. A limiting arc frame is rotatably provided at the top end of the sleeve, which is used to prevent the supporting side block and the sleeve from separating after the top end of the supporting side block changes from a vertical state to a horizontal state.

[0012] Furthermore, a connecting rod is fixedly provided at the inner end of the magnetic block. The connecting rod slides into the movable rod from the end face of the fixed block and is provided with a shifting frame. A track groove is provided on the movable rod at the position corresponding to the movement of the shifting frame. The shifting frame moves horizontally within the track groove, causing the magnetic block connected by the connecting rod to move closer to or away from the metal plate.

[0013] Furthermore, a connecting unit b is longitudinally arranged inside the track slot. The connecting unit b includes a first semi-circular arc plate and a second semi-circular arc plate. A plug rod is horizontally arranged on the inner side of the first semi-circular arc plate, passing through the track slot and cooperating with the second semi-circular arc plate.

The lower end of the support rod is fixedly arranged with the reference sub-rod. During the separation or reversal of the two reference rods, the vertical plate and the support rod, which are in relative sliding engagement, drive the movable rod on the corresponding side to move synchronously at the opening a.

[0014] Furthermore, a scale area is provided on one side of the slide and on one side of the vertical plate.

[0015] The beneficial effects of this invention are reflected in: This invention, through the setting of side rods, bottom reference components, and intermediate positioning components, enables the measurement and calculation work to be carried out in advance, so as to calculate the horizontal deviation between the actual construction pile entry point and the designed pile position in advance, and to quickly assemble the simple positioning tool for inclined piles on site, thereby improving the positioning efficiency of the pile entry point and avoiding the risk of pile position deviation caused by calculation errors during on-site measurement and layout. It also solves the problems caused by the original inclined pile construction process of erecting inclined guide frames. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-9 This invention discloses a positioning method, which specifically includes the following steps: S1. Surveying and mapping stage: By measuring and setting out, the center diameter lines at the top elevation of multiple design pile positions are laid out. Then, the elevation of the construction site and the top elevation of each design pile position are measured using measuring instruments. S2. Calculation stage: Apply the principle of trigonometric functions to calculate the horizontal distance deviation corresponding to different elevations of the construction site; S3. Production stage: Construct a frame, set a reference main rod 2 at one end of the frame, and set multiple positioning rods 6 at intervals on the frame. The distance between each positioning rod 6 and the reference main rod 2 is equal to the value of each horizontal distance deviation. S4. Usage stage: Align the center of the reference main rod 2 with the center of the top elevation of the designed pile position, measure the elevation of the construction site, and find the positioning rod 6 corresponding to the elevation on a frame based on the elevation to locate the actual construction pile entry point.

[0020] In the specific implementation, the center diameter line of the pile at the top elevation of the designed pile position is first laid out. The adjustment mechanism 8 is used to adjust and determine the relative length of the two reference auxiliary rods 3 of the sliding combination on the reference main rod 2 included on the bottom reference component according to the diameter of the designed pile position. The first verification hole 4 on the reference main rod 2 and the second verification hole 5 on the two reference auxiliary rods 3 are aligned with the center and two end points of the center diameter line, respectively, to complete the determination of the entry point of the pile at the top elevation of the designed pile position. Then, the elevation of the construction site is measured using a measuring instrument (total station), and the positioning rod 6 corresponding to the elevation is found on the simple positioning tool of the combined inclined pile. The position of the positioning rod 6 is the entry position of the inclined pile at the original ground elevation, thus completing the rapid positioning of the entry point.

[0021] Before construction, the principle of trigonometric functions needs to be applied to calculate the horizontal deviation of the inclined pile entry point corresponding to different ground elevations based on the survey data. This deviation is then marked and displayed in the simple inclined pile positioning tool to quickly and conveniently determine the inclined pile entry position at the original ground elevation, thereby completing the rapid positioning of the entry point.

[0022] A simple positioning tool for inclined piles, applied to a positioning method, includes two parallel side bars 1; The bottom reference assembly is set on the centerline of the designed pile position. It includes a reference main rod 2 set at the bottom of the two side rods 1 and two reference secondary rods 3 slidably set on the reference main rod 2. The reference secondary rods 3 are fixedly connected to the corresponding side rods 1, and drive the side rods 1 to move relative to the reference main rod 2 to adjust the distance between the two side rods 1. A first verification hole 4 is provided at the center point of the corresponding designed pile position on the reference main rod 2, and a second verification hole 5 is provided at both ends of the center line of the corresponding designed pile position on the two reference auxiliary rods 3; The intermediate positioning assembly includes a plurality of positioning rods 6 disposed between the two side rods 1 and arranged along the length direction of the side rods 1. Each positioning rod 6 has a connecting unit a7 at both ends, and the connecting unit a7 is used to detachably fix the positioning rod 6 at the corresponding position on the side rod 1.

[0023] In practice, at the construction site, based on the diameter and length of the designed pile position, the reference auxiliary rod 3 on the relative sliding reference main rod 2, and the length of the multiple positioning rods 6 included in the intermediate positioning assembly are adjusted, and the connecting unit a7 is used to sequentially and detachably combine the multiple positioning rods 6 between the two parallel side rods 1. Among them, the first verification hole 4 opened on the reference main rod 2 and the second verification hole 5 correspondingly machined on the two reference auxiliary rods 3 are respectively aligned with the center and two end points of the center diameter line of the designed pile position to complete the positioning of the entry point at the designed pile position elevation; Furthermore, by applying the principle of trigonometric functions, the horizontal deviation corresponding to different site elevations is calculated, that is, the relative distance between the assembled positioning rod 6 and the reference main rod 2, and the horizontal deviation reading is marked.

[0024] In one embodiment, the reference main rod 2 is provided with an adjustment mechanism 8, which is used to drive and adjust the spacing of the side rods 1 fixed on the reference auxiliary rods 3 distributed at both ends; The adjustment mechanism 8 includes a rotating block 81 rotatably mounted at the center of the upper end of the reference main rod 2, and a lead screw b82 passing through the rotating block 81. The lead screw b82 has two threaded portions that are symmetrical and rotate in opposite directions. A support vertical plate 31 is provided at the upper end of the reference auxiliary rod 3 near the center of the reference main rod 2. The support vertical plate 31 is adapted to rotate and connect with the threaded portions. With this design, by rotating the rotating block 81, which is rotatably mounted with a central slot on the reference main rod 2, and by fixing the lead screw b82 through the end face of the rotating block 81, the rotating block 81 drives the lead screw b82 to rotate. This causes the support vertical plate 31, which is connected to the two symmetrical and oppositely rotating threaded portions machined on the lead screw b82, and the corresponding reference auxiliary rod 3 welded to the support vertical plate 31, to move linearly under the limitation of the reference main rod 2. This achieves the adjustment of the relative distance between the two reference auxiliary rods 3 and the side rod 1 welded to the outer end of the reference auxiliary rod 3, which meets the construction requirements of the designed pile position diameter and is universally applicable.

[0025] In one embodiment, the positioning rod 6 consists of a hollow tube 61 and two movable rods 62. The hollow tube 61 has openings a at both ends. The adjacent ends of the two movable rods 62 are slidably inserted into the openings a and connected within the hollow tube 61 by elastic ropes 63. This design allows the two movable rods 62, slidably installed at the openings a at both ends of the hollow tube 61 and connected by elastic ropes 63 at their adjacent ends, to move the movable rods 62 to both sides relative to the hollow tube 61 according to the diameter of the designed pile, achieving a length adjustment effect.

[0026] In one embodiment, the connecting unit a7 includes a fixing block 71 disposed on the movable rod 62 corresponding to the end of the side rod 1, a magnetic block 72 disposed on the outer end of the fixing block 71 and moving along the length direction of the movable rod 62, and a vertically movable support side block 73 disposed on one side facing each other on the two side rods 1. The support side block 73 is provided with an opening b at the end corresponding to the movable rod 62, and a metal plate that cooperates with the magnetic block 72 is disposed at the inner end of the opening b. With this design, by welding the fixing block 71 to the end of the corresponding side rod 1 on the movable rod 62, and machining the inner horizontally moving magnetic block 72 at the outer end of the fixing block 71, when the magnetic block 72 moves horizontally to the outer end and is on the same vertical plane as the end face of the fixing block 71, it will be magnetically fixed with the metal plate installed at the inner end of the opening b machined on the support side block 73, thereby achieving the fixation of the positioning rod 6 at any horizontal position between the two parallel side rods 1.

[0027] It should be noted that the support side block 73, which is slotted and movable at the inner end of the side rod 1, can be operated and fixed as a whole between the two support side blocks 73. This simplifies the subsequent operation steps, reduces redundant work and repetitive operations, and thus improves the overall efficiency.

[0028] In one embodiment, sleeves 74 are provided through the end faces of both support side blocks 73, one sleeve 74 is fitted with a lead screw a75, which is rotatably mounted on the end face of the corresponding side rod 1, and the other sleeve 74 is fitted with a guide rod 76, which is fixedly mounted on the end face of the corresponding side rod 1. The bottom end of the sleeve 74 is provided with a limiting plate 741, which is used to support the support side block 73 and prevent it from moving on the sleeve 74. The top end of the sleeve 74 is rotatably provided with a limiting arc frame 742, which is used to prevent the support side block 73 and the sleeve 74 from separating after the top end of the support side block 73 changes from a vertical state to a horizontal state. This design, through the sleeve 74 machined through the end face of the support side block 73, and the internal thread machined in the sleeve 74 that connects with the lead screw a75, rotates the lead screw a75. This drives the sleeve 74 connected to it and the support side block 73, which is fixed at the upper limit of the sleeve 74, to move along the length direction of the two parallel side rods 1 under the limit of the guide rod 76 that slides and guides it in the other sleeve 74. This allows the two support side blocks 73 supported by the positioning rods 6 to move according to the length of the two parallel side rods 1. This achieves the adjustment of the relative distance between the positioning rods 6 and the reference main rod 2 according to the elevation of the site during actual construction.

[0029] It should be noted that the limiting plate 741 welded to the bottom of the sleeve 74 and the limiting arc frame 742 installed at the top of the sleeve 74 using a rotating shaft will, after the support side block 73 is coaxially sleeved and assembled with the sleeve 74, limit plate 741 will prevent the support side block 73 from continuing to move downward relative to limit plate 741, and limiting arc frame 742 will change from a vertical state to a horizontal state to limit the top of support side block 73.

[0030] Additional notes: An operating handle for operation is installed at the bottom of the lead screw A75.

[0031] In one embodiment, a connecting rod is fixedly provided at the inner end of the magnetic block 72. The connecting rod slides from the end face of the fixed block 71 into the movable rod 62 and is provided with a shift bracket 77. A track groove 621 is provided on the movable rod 62 at the position corresponding to the movement of the shift bracket 77. The shift bracket 77 moves horizontally within the track groove 621, causing the magnetic block 72 connected by the connecting rod to move closer to or away from the metal plate. With this design, by using the connecting rod installed at the inner end of the magnetic block 72 and the track groove 621 machined on the movable rod 62, the shift bracket 77, integrally formed at the end of the connecting rod away from the magnetic block 72, can move horizontally on the end face of the fixed block 71. When the magnetic block 72 moves to the point where its outer end face is on the same plane as the fixed block 71, it will be magnetically attracted and fixedly connected to the metal plate through the contact between the outer end face of the magnetic block 72 and the metal plate, thus realizing the fixation of the positioning rod 6 between the two parallel supporting side blocks 73.

[0032] As can be further explained, when the magnetic block 72 moves inward along the track slot 621 under the drive of the shifter 77, the magnetic block 72 separates from the metal plate, thereby realizing the adjustment of the vertical distance between the positioning rod 6 and the two parallel supporting side blocks 73.

[0033] In one embodiment, a connecting unit b9 is longitudinally arranged inside the track slot 621. The connecting unit b9 includes a first semi-circular arc plate 91 and a second semi-circular arc plate 92. A plug rod 93 is horizontally arranged on the inner side of the first semi-circular arc plate 91, passing through the track slot 621 and cooperating with the second semi-circular arc plate 92. A vertical plate 10 is vertically arranged on the outer side of the first semi-circular arc plate 91. A sliding groove is provided on the vertical plate 10 corresponding to the end face of the first semi-circular arc plate 91. A slider that moves in cooperation within the sliding groove is provided on the outer end of each first semi-circular arc plate 91. A support rod 11 is slidably arranged on the vertical plate 10. The lower end of the support rod 11 is fixedly arranged with the reference auxiliary rod 3. During the separation or reciprocation of the two reference rods 3, the vertical plate 10 and the support rod 11 drive the corresponding movable rod 62 on the open a to move synchronously. This design allows for the installation of a first semi-circular plate 91 and a second semi-circular plate 92 at the corresponding track slot 621 on the movable rod 62. A rod 93 welded to the inner side of the first semi-circular plate 91 is horizontally inserted through the track slot 621 and connected to the slot on the second semi-circular plate 92. A slider welded to the outer end of the first semi-circular plate 91 moves within a vertically opened groove on the corresponding end face of the vertical plate 10. This allows the spacing of multiple positioning rods 6 installed between the two side rods 1 to be determined within the groove, and they can be arranged sequentially according to the ground elevation. Furthermore, by using a support rod 11 that is slidably installed in a slot at the bottom of the vertical plate 10, when the positioning rod 6 is moved and its position between the two side rods 1 is determined, the positioning rod 6 connected to the vertical plate 10 via the connecting unit b9 will slide relative to the support rod 11, thereby achieving the movement and fixation of the positioning rod 6 at any position between the two side rods 1. In addition, the lower end of the support rod 11 is welded and fixed to the reference sub-rod 3. When the reference sub-rod 3 is subjected to external force and moves horizontally, the movable rod 62 slidably installed at the open ends a of the hollow tube 61 will be driven synchronously through the support connection between the vertical plate 10 and the support rod 11 to adjust its length, thereby realizing the adjustment of the distance between the two parallel side rods 1 and meeting the construction requirements of the actual pile diameter.

[0034] It should be noted that the contacting end faces of the first semicircular plate 91 and the second semicircular plate 92 are made of metal and magnetic materials, which realizes the magnetic fixation of the connecting unit b9 at the corresponding position on the movable rod 62.

[0035] In one embodiment, a graduated area is provided on one side of the slide and on the upper surface of the vertical plate 10. This design allows for the display of numerical values ​​through the graduated area machined on one side of the vertical plate 10, enabling the determination of the horizontal deviation degree of the multiple positioning rods 6 between the two parallel side rods 1.

[0036] Preferably, the corresponding horizontal deviation reading is marked on the scale area of ​​the vertical plate 10 on one side of the positioning rod 6, which is determined by the distance combination between the two parallel side rods 1 and the bottom reference component, using a pasted label, so as to intuitively identify the position of the target positioning rod 6 and quickly locate the inclined pile entry position at the original ground elevation.

[0037] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0039] Additionally, "multiple" refers to two or more.
