Description

Technical Field

[0001] This utility model relates to the field of construction engineering technology, specifically a rapid positioning device for the center point of a three-pile cap structural column. Background Technology

[0002] In construction projects (building projects), a foundation system consisting of pile foundations, pile caps, and structural columns is frequently used. Common pile cap types include single-pile pile caps, double-pile pile caps, triple-pile pile caps, and quadruple-pile pile caps. Single-pile, double-pile, and quadruple-pile pile caps are all regular rectangular shapes, making the positioning of the pile cap and structural columns relatively easy to control. Triple-pile pile caps, on the other hand, are irregular polygonal structures, making the positioning of the pile cap and structural columns more difficult to control.

[0003] Traditional methods for positioning foundations and structural columns involve marking and marking lines for each foundation and structural column individually. This is inefficient and makes it difficult to maintain consistency in the positioning and dimensions of foundations at different locations. Construction quality is entirely controlled by the workers who mark and mark the lines, making them highly susceptible to human error and resulting in poor overall appearance of the foundations, significant misalignment of structural columns, and inconsistent misalignment directions. This leads to substantial waste of labor and poor construction quality. In particular, three-pile foundations, with their irregular polygonal shapes, are difficult to control uniformly. The positioning of the central structural column is also challenging, causing the reinforcing steel to deviate from the central axis. Consequently, the structural columns of a row of foundations are not aligned on a single axis after construction, resulting in significant misalignment that is difficult to rectify.

[0004] Based on this, the present invention designs a rapid positioning device for the center point of a three-pile cap structural column to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid positioning device for the center point of a three-pile cap structural column, comprising a positioning frame, wherein the positioning frame includes three straight rods and three angled members; the three straight rods are arranged in a triangle; adjacent straight rods are connected by angled members, each angled member including two sliding rods arranged in a V-shape, with the included angle between the two sliding rods being 60°, so that the three straight rods and three angled members enclose an equilateral triangular positioning cavity, the two sliding rods respectively slidingly engaging with the two adjacent straight rods, the sliding engagement direction of the sliding rods and the straight rods being consistent with the length direction of the straight rods, so that the three straight rods and three angled members can move away from or closer to each other, thereby adjusting the side length of the positioning cavity.

[0006] As a further embodiment of this utility model, the straight rod is provided with a sliding groove extending through both ends of its length direction, and the sliding rod is slidably disposed within the sliding groove provided in the straight rod.

[0007] As a further embodiment of this utility model, one of the inner cavity of the slide groove and the surface of the slide rod is fixedly provided with a protrusion, and the other is provided with a limiting groove. The protrusion is slidably disposed in the limiting groove, and the limiting groove is provided with a limiting member to prevent the protrusion from disengaging from the limiting groove, and to prevent the slide rod from disengaging from the slide groove along the length direction of the slide groove.

[0008] As a further embodiment of this utility model, the side of the straight rod facing the center of the positioning cavity is the first side surface, and one side of the sliding groove is connected to the first side surface, so that the side of the sliding rod facing the center of the positioning cavity and the first side surface are on the same plane.

[0009] As a further embodiment of this utility model, the protrusion is provided on the top or bottom surface of the inner cavity of the slide groove or the slide rod.

[0010] As a further embodiment of this utility model, the cross section of the slide groove perpendicular to the length direction is a first cross section, the height of the first cross section near the first side is less than the height away from the first side, and the cross section of the slide rod perpendicular to the length direction matches the shape of the first cross section.

[0011] As a further embodiment of this utility model, the center of the straight rod along its length direction is provided with a position mark or a support rod for pulling the wire.

[0012] As a further embodiment of this utility model, a handle is fixedly provided on the top surface of the straight rod.

[0013] As a further embodiment of this utility model, the straight rod has a second side parallel to the first side, and there is a preset distance between the second side and the first side.

[0014] As a further embodiment of this utility model, a locking screw is threaded onto the straight rod, and the locking screw is used to contact the slide rod to lock the position of the slide rod in the slide groove.

[0015] This utility model has the following beneficial effects:

[0016] 1. This device forms an equilateral triangular positioning cavity within the positioning frame. The positioning frame is positioned by the contact of the three included angles of the positioning cavity with steel nails. Subsequently, the center of the three pile foundations is determined by the lines connecting the different included angles of the positioning cavity with the center of the relative straight rod.

[0026] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0027] Please see Figure 1-4This utility model provides a technical solution: a rapid positioning device for the center point of a three-pile cap structural column, including a positioning frame, which includes three straight rods 1 and three angled pieces; the three straight rods 1 are arranged in a triangle; adjacent straight rods 1 are connected by angled pieces, each angled piece including two sliding rods 2 arranged in a V-shape, with the included angle between the two sliding rods 2 being 60°, so that the three straight rods 1 and the three angled pieces enclose an equilateral triangle positioning cavity, the two sliding rods 2 respectively slide and engage with the two adjacent straight rods 1, and the sliding engagement direction of the sliding rods 2 and the straight rods 1 is consistent with the length direction of the straight rods 1, so that the three straight rods 1 and the three angled pieces can move away from or closer to each other, thereby adjusting the side length of the positioning cavity;

[0028] Since the included angle between the two sliding rods 2 in the corner piece is 60°, the positioning cavity formed by the three corner pieces and the three straight rods 1 is an equilateral triangle. During subsequent adjustment, since the included angle between the two sliding rods 2 in the corner piece remains unchanged, no matter how the gap between the straight rods 1 is adjusted, the positioning cavity formed by the three corner pieces and the three straight rods 1 will always be an equilateral triangle. However, due to the change in the distance between the straight rods 1, the projected area of ​​the positioning cavity in the vertical direction will change, and the side length of the positioning cavity will also change.

[0029] In use, first, steel nails are driven into the center points of the three pile foundations, forming an equilateral triangle. Next, the three straight rods and three angled members are positioned far apart. Figure 2As shown, when the straight rods 1 move away from each other, the sliding rod 2 will slide relative to the straight rods 1 in a direction away from the center of the length of the straight rods 1. At this time, the distance between the straight rods 1 increases, and the distance between the corner pieces also increases. Since the included angle between the sliding rods 2 is 60°, the positioning cavity formed by the three straight rods 1 and the three corner pieces is always an equilateral triangle, but the area of ​​the positioning cavity will increase, thus increasing the side length of the positioning cavity. The positioning cavity is adjusted to a suitable area based on the area of ​​the equilateral triangle formed by the three connected steel nails. Then, the positioning frame is placed on the pile foundation, so that the three steel nails are respectively located at the three included angles of the positioning cavity, and at the same time, all three steel nails are in contact with two sides of the positioning cavity. That is to say, the steel nails need to be in contact with two sliding rods 2 or two straight rods 1 at the same time to ensure the accurate position of the positioning frame. Next, the perpendicular bisectors on the three sides of the equilateral triangle intersect the equilateral triangle. Based on the central characteristics, a thin rope is tied to a steel nail, and the other end of the rope is positioned at the center of the straight rod 1 opposite to the current steel nail. The above operation is repeated until at least two steel nails are tied with thin ropes. The staggered positions between the thin ropes are the center points of the three pile foundations. This device forms an equilateral triangular positioning cavity within the positioning frame. The positioning frame is positioned by the three included angles of the positioning cavity contacting the steel nails respectively. Then, the center of the three pile foundations is determined by the lines connecting the different included angles of the positioning cavity to the center of the opposite straight rod 1. This achieves rapid positioning of the center points of the three pile caps and structural columns. The structure is simple, easy to use, has high construction quality, low manufacturing cost, and can be reused. It improves work efficiency, reduces labor costs in engineering construction, and avoids errors and deviations caused by manual operation, thereby improving the quality of the engineering entity and increasing the first-time molding qualification rate.

[0030] Furthermore, the area of ​​the positioning cavity formed by the positioning frame in this device is adjustable. The side length of the positioning cavity can be adjusted according to the size of the three-pile foundation, which can adapt to three-pile foundations of different sizes within a certain range, making it more widely applicable and eliminating the need for customization based on the size of the three-pile foundation.

[0031] Furthermore, when placing the positioning frame on the pile foundation, the positioning frame is first adjusted according to the size of the equilateral triangle formed by the steel nails on the three pile foundations, so that the size of the positioning cavity is larger than the size of the equilateral triangle formed by the steel nails on the three pile foundations. This makes it easier for the positioning frame to be placed on the pile foundation and prevents interference between the positioning frame and the top caps of the steel nails. After the positioning frame is placed on the pile foundation, the straight rods are controlled to move closer to each other, reducing the size of the positioning cavity, so that the three steel nails are positioned at the three included angles of the positioning cavity.

[0032] Furthermore, when selecting steel nails, choose nails with the same diameter to ensure accurate positioning of the final positioning frame when fitting the positioning frame onto the steel nails.

[0033] This application does not impose any restrictions on the sliding fit structure between the slide rod 2 and the straight rod 1, as long as the sliding fit between the slide rod 2 and the straight rod 1 can be achieved;

[0034] The first example of the sliding engagement between the slide rod 2 and the straight rod 1 is that the slide rod 2 has a groove 11 that passes through the end away from the included angle. The length direction of the groove 11 is the same as the length direction of the slide rod 2. The straight rod 1 is slidably arranged in the groove 11 of the slide rod 2 to achieve the sliding engagement between the slide rod 2 and the straight rod 1.

[0035] Figure 2 A second example of sliding engagement between slide rod 2 and straight rod 1 is disclosed. In this example, straight rod 1 has a groove 11 extending through both ends of its length direction. Slide rod 2 is slidably disposed in the groove 11 of straight rod 1, thereby realizing sliding engagement between slide rod 2 and straight rod 1.

[0036] The following is a further description using a second example of the sliding engagement between slide bar 2 and straight bar 1;

[0037] In this example, further, one of the inner cavity of the slide groove 11 and the surface of the slide rod 2 is fixedly provided with a protrusion 12, and the other is provided with a limiting groove 21. The protrusion 12 is slidably disposed in the limiting groove 21. The limiting groove 21 is provided with a limiting member to prevent the protrusion 12 from disengaging from the limiting groove 21, and to prevent the slide rod 2 from disengaging from the slide groove 11 along the length direction of the slide groove 11.

[0038] like Figure 3 As shown, when the protrusion 12 is fixedly installed in the inner cavity of the slide groove 11, two protrusions 12 are fixedly installed in the inner cavity of the slide groove 11. The two protrusions 12 are respectively installed at both ends of the slide groove 11 in the length direction. The slide rod 2 and the protrusion 12 are respectively provided with limiting grooves 21 in the length direction of the two slide rods 2. The end of the limiting groove 21 away from the included angle in the length direction has a limiting member to prevent the protrusion 12 from leaving the limiting groove 21 from both ends in the length direction of the limiting groove 21.

[0039] like Figure 3 As shown, the end of the limiting groove 21 away from the included angle in the length direction has a limiting member. The limiting member can prevent the protrusion 12 from disengaging from the limiting groove 21. When the protrusion 12 cannot disengage from the limiting groove 21, it means that the slide rod 2 cannot disengage from the slide groove 11 opened in the straight rod 1, thereby preventing the slide rod 2 from separating from the corner piece, preventing the straight rod 1 from separating from the corner piece during use or transportation, and ensuring the safety of the positioning frame.

[0040] Since the end of the limiting groove 21 away from the included angle in the length direction has a limiting element, the two protrusions 12 are respectively set at both ends of the sliding groove 11 in the length direction. This allows the sliding rod 2 to extend out of the sliding groove 11 as much as possible, preventing the protrusions 12 from affecting the sliding stroke of the sliding rod 2 in the sliding groove 11.

[0041] Of course, the protrusion 12 can also be set on the slide bar 2, and the limiting groove 21 can be opened in the slide groove 11, which can also achieve the separation of the straight bar 1 and the angled piece.

[0042] The limiting component can be a boss or a pin, such as Figure 3 As shown, in some examples, the limiting member is the straight rod 1 itself. By controlling the length of the limiting groove 21, the limiting groove 21 is made not to pass through the end of the slide rod 2 away from the included angle, which can also prevent the protrusion 12 from disengaging from the limiting groove 21.

[0043] Furthermore, the side of the straight rod 1 facing the center of the positioning cavity is the first side surface 13, and one side of the slide groove 11 is connected to the first side surface 13, so that the side of the slide rod 2 facing the center of the positioning cavity is on the same plane as the first side surface 13.

[0044] like Figure 2 As shown, when the steel nail is positioned at the three included angles of the positioning cavity, there are two situations. The first situation is that the steel nail will contact the first side 13 of the two straight rods 1 to achieve the positioning of the positioning frame. The second situation is that the distance between the straight rods 1 is too large, and the steel nail does not contact the first side 13 of the straight rod 1, but contacts the side of the two sliding rods 2 facing the center of the positioning cavity to achieve the positioning of the positioning frame. When the side of the sliding rod 2 facing the center of the positioning cavity is on the same plane as the first side 13, it can be ensured that the side of the sliding rod 2 facing the center of the positioning cavity is always in contact with the steel nail. The surface used to contact the steel nail (the first side 13 and the side of the sliding rod 2 facing the center of the positioning cavity) is always the same surface, ensuring that the positioning frame can be positioned by the steel nail within the adjustment range of the positioning frame, and preventing the situation of being unable to be positioned within the adjustment range of the positioning frame.

[0045] Optional, such as Figure 4 As shown, in this example, the protrusion 12 is provided on the top or bottom surface of the inner cavity of the slide groove 11. After the protrusion 12 is provided on the top or bottom surface of the inner cavity of the slide groove 11, the cooperation between the protrusion 12 and the limiting groove 21 can prevent the slide rod 2 from leaving the slide groove 11 through the opening of the first side 13, prevent the slide rod 2 from disengaging from the slide groove 11, and ensure the stable use of the positioning frame.

[0046] Optional, such as Figure 4As shown, in some other examples, the cross section of the slide groove 11 perpendicular to the length direction is the first cross section. The height of the first cross section near the first side 13 is less than the height away from the first side 13. The cross section of the slide rod 2 perpendicular to the length direction matches the shape of the first cross section. That is, the opening height of the slide groove 11 on the first side 13 is less than the height of the part of the slide groove 11 away from the first side 13. At the same time, the shape of the slide rod 2 matches the shape of the first slide groove 11. Therefore, it can also prevent the slide rod 2 from leaving the slide groove 11 through the opening on the first side 13, thereby achieving the effect of preventing the slide rod 2 from detaching from the slide groove 11 and ensuring the stable use of the positioning frame.

[0047] Furthermore, the center of the straight rod 1 along its length is marked with a position marker or a support rod for pulling the line. After the positioning frame is positioned, the center of the three-pile foundation needs to be positioned using a thin rope. Positioning the center of the three-pile foundation using a thin rope utilizes the fact that the perpendicular bisectors of the three sides of an equilateral triangle intersect at the center of the equilateral triangle. Therefore, the thin rope needs to be positioned at the center of the straight rod 1. The presence of a position marker or a support rod for pulling the line at the center of the straight rod 1 along its length allows for quick positioning of the thin rope on the straight rod 1, improving the efficiency of positioning the center of the three-pile foundation.

[0048] Furthermore, such as Figure 1-2 As shown, a handle 14 is fixedly installed on the top surface of the straight rod 1. When adjusting the distance between the straight rods 1 to adjust the side length of the positioning cavity, it is necessary to make the straight rods 1 move away from each other or move closer together. After the handle 14 is fixedly installed on the top surface of the straight rod 1, the handle 14 can be held to adjust the distance between the straight rods 1, making it more convenient to adjust the distance between the straight rods 1.

[0049] Furthermore, the straight rod 1 has a second side parallel to the first side 13, and there is a preset distance between the second side and the first side 13. After the center point of the three-pile cap is positioned by the positioning frame, as shown... Figure 1-2 As shown, the outer edge of the three-pile cap can also be located by the second side. By pulling a line on the second side, the thin line is made to fit the second side. The thin lines pulled out from the second side of the three straight rods 1 intersect to form the outer edge of the three-pile cap, which further improves the positional accuracy of the subsequent three-pile cap and structural column, and improves the final project quality.

[0050] Furthermore, a locking screw 15 is threaded onto the straight rod 1, which is used to contact the slide rod 2 to lock the position of the slide rod 2 in the slide groove 11;

[0051] After adjusting the side length of the positioning cavity, as follows: Figure 1-2As shown, the rotatable locking screw 15 is brought close to the slide rod 2 and abuts against the surface of the slide rod 2. The slide rod 2 is locked by the friction between the locking screw 15 and the slide rod 2, preventing the slide rod 2 from moving in the slide groove 11. This prevents the slide rod 2 from moving during the subsequent positioning process, which would cause changes in the size of the positioning cavity, thereby ensuring the accurate positioning of the three-pile foundation and the center of the structural column.

[0052] There is at least one locking screw 15. Based on the characteristics of a triangle, locking any one of the straight rods 1 and the sliding rod 2 by locking the locking screw 15 can achieve overall locking of the positioning frame.

[0053] Furthermore, such as Figure 2 As shown, the external corners at the intersection of the two sliding rods 2 in the corner piece are chamfered to prevent the external corners from injuring workers.

[0054] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0055] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application.
