Abstract

This utility model relates to the field of bolt hole pre-embedded sleeve construction technology, and in particular to a positioning and marking device for bolt hole pre-embedded sleeve construction, comprising: a template, a horizontal bar, a horizontal positioning rod, and a scale line. A horizontal bar is placed on one side of the top of the template, and a vertical bar is rotatably connected to one end of the horizontal bar. Baffles are fixedly connected to the sides of the horizontal bar and the vertical bar at their closest points, and both baffles are in contact with the template. This utility model, through the integrated frame constructed by the horizontal bar and the vertical bar, combined with the sliding adjustment structure of the horizontal positioning rod and the vertical positioning rod, allows a single person to independently complete the positioning operation—no need for a dedicated person to fix the reference end, nor for multiple people to coordinate calibration. The coordinates can be read by the scale pointer and the scale line, and the positioning time can be shortened to less than 1 minute, which is 3-5 times more efficient than the traditional tape measure method. In the case of batch pre-embedded sleeves, it can effectively reduce manpower input, reduce labor costs, and avoid delays in construction progress due to personnel coordination problems.

Description

Technical Field

[0001] This utility model relates to the field of bolt hole pre-embedded sleeve construction technology, and in particular to a positioning and setting-out device for bolt hole pre-embedded sleeve construction. Background Technology

[0002] In construction and machinery installation projects, the positioning accuracy of bolt hole pre-embedded sleeves directly determines the quality of subsequent component assembly. However, most construction scenarios in the industry still rely on measuring tapes for positioning and layout. While this traditional method is low-cost and readily available, it is cumbersome and requires at least two people to work together: one to hold the zero mark of the measuring tape, and the other to pull the tape and visually calibrate the horizontal / vertical position. Improper coordination requires repeated adjustments, and a single positioning takes an average of 3-5 minutes. When dealing with batches of pre-embedded sleeves (such as 20-30 sleeves per batch), the cumulative time is extremely long, resulting in high labor costs and severely slowing down the construction progress.

[0003] Meanwhile, measuring with a tape measure is prone to multiple errors, leading to secondary losses in efficiency: problems such as viewing angle deviation during reading, the tape measure not being fully straightened, and hand shaking at the reference end often cause the deviation to exceed the allowable ±2mm, requiring multiple measurements to be taken and the average value taken; when there are obstacles on the template surface or when working at height, the tape measure is difficult to fit and extend or is easily shaken by the wind, requiring additional calculations or additional manpower for stabilization, further increasing the number of operation steps; and the positioning points marked only by a marker pen are easily blurred and disappeared due to pollution and friction at the construction site, requiring remeasurement and repositioning.

[0004] Therefore, it is necessary to provide a new positioning and layout device for the construction of bolt hole pre-embedded sleeves to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a positioning and layout device for the construction of bolt hole pre-embedded sleeves.

[0006] The positioning and marking device for bolt hole pre-embedded sleeve construction provided by this utility model includes: a template, a horizontal bar, a horizontal positioning bar, and a scale line. A horizontal bar is placed on one side of the top of the template, and a vertical bar is rotatably connected to one end of the horizontal bar. Baffles are fixedly connected to the sides of the horizontal bar and the vertical bar at their close ends. Both baffles are in contact with the template. A horizontal positioning bar is slidably connected to the top of the horizontal bar, and a vertical positioning bar is slidably connected to the top of the vertical bar. A positioning groove is opened in the middle of the horizontal positioning bar and the vertical positioning bar. The intersection of the two positioning grooves is the construction point. A scale line is opened at the top of the horizontal bar and the vertical bar, and a scale pointer is opened at one end of the horizontal positioning bar and the vertical positioning bar.

[0007] Preferably, both the horizontal and vertical bars have internal grooves, with L-shaped tie rods slidably connected to the inner walls of the grooves and threaded rods rotatably connected to the inner walls of the grooves. The L-shaped tie rods are threadedly connected to the threaded rods, and one end of the threaded rod extends out of the groove while the other end is fixedly connected to a hexagonal block.

[0008] Preferably, a first slot is provided at the end of the vertical positioning rod near the horizontal positioning rod, and two second slots are provided at the end of the horizontal positioning rod near the vertical positioning rod. The two second slots are perpendicular to the axis connecting line of the horizontal positioning rod. A pin is inserted into the inner wall of the first slot, and the pin is inserted into one of the second slots.

[0009] Preferably, both the horizontal positioning rod and the vertical positioning rod have a threaded fixing bolt at one end.

[0010] Preferably, both the crossbars and vertical bars are made of lightweight alloy material.

[0011] Preferably, an anti-slip pad is fixedly connected to the bottom end of the L-shaped pull rod away from the threaded rod. The anti-slip pad is made of nitrile rubber and has diamond-shaped anti-slip patterns on its side.

[0012] Compared with related technologies, the positioning and setting-out device for bolt hole pre-embedded sleeve construction provided by this utility model has the following advantages: Simplified operation process, reduced labor costs and significantly improved efficiency: The device uses an integrated frame constructed with horizontal and vertical bars, combined with a sliding adjustment structure for the horizontal and vertical positioning rods, allowing a single person to complete the positioning operation independently—no need for a dedicated person to fix the reference end, nor for multiple people to coordinate calibration. The coordinates can be read simply by using the scale pointer and scale lines, reducing the positioning time to less than 1 minute, which is 3-5 times more efficient than the traditional tape measure method. In the case of batch pre-embedded sleeves, it can effectively reduce manpower input, lower labor costs, and avoid delays in construction progress due to personnel coordination issues. To reduce measurement errors and avoid secondary efficiency losses: The device utilizes a "pin-locking XY axis perpendicularity" structure to eliminate perpendicularity deviations caused by traditional visual calibration. Simultaneously, the visual coordination of the scale lines and pointers eliminates angular deviations in tape measure readings, and the fixed structure of the horizontal and vertical bars prevents the reference end from wobbling. The overall positioning deviation can be controlled within ±1mm, meeting specification requirements and eliminating the need for multiple measurements and averaging. Furthermore, the double locking of the L-shaped pull rod and fixing bolts ensures stable positioning, eliminating the need for rework due to errors and completely preventing secondary efficiency losses.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figures 1 to 4 A positioning and marking device for bolt hole pre-embedded sleeve construction includes: a template, a horizontal bar 1, a horizontal positioning rod 4, and a scale line 6. A horizontal bar 1 is placed on one side of the top of the template. A vertical bar 2 is rotatably connected to one end of the horizontal bar 1. Baffles 3 are fixedly connected to the sides of the ends of the horizontal bar 1 and the vertical bar 2 that are close to each other. Both baffles 3 are in contact with the template. A horizontal positioning rod 4 is slidably connected to the top of the horizontal bar 1. A vertical positioning rod 5 is slidably connected to the top of the vertical bar 2. A positioning groove 11 is opened in the middle of the horizontal positioning rod 4 and the vertical positioning rod 5. The intersection of the two positioning grooves 11 is the construction point. A scale line 6 is opened at the top of the horizontal bar 1 and the vertical bar 2. A scale pointer 7 is opened at one end of the horizontal positioning rod 4 and the vertical positioning rod 5. A fixing bolt 16 is threadedly connected to one end of the horizontal positioning rod 4 and the vertical positioning rod 5. The horizontal bar 1 and the vertical bar 2 are both made of lightweight alloy material.

[0018] Both the horizontal bar 1 and the vertical bar 2 have internal grooves 8. An L-shaped tie rod 9 is slidably connected to the inner wall of the groove 8. A threaded rod 10 is rotatably connected to the inner wall of the groove 8. The L-shaped tie rod 9 is threadedly connected to the threaded rod 10. One end of the threaded rod 10 extends out of the groove 8 and the other end is fixedly connected to a hexagonal block 12. An anti-slip pad is fixedly connected to the bottom end of the L-shaped tie rod 9 away from the threaded rod 10. The anti-slip pad is made of nitrile rubber and has diamond-shaped anti-slip patterns on its side.

[0019] The vertical positioning rod 5 has a first slot 13 at one end near the horizontal positioning rod 4, and the horizontal positioning rod 4 has two second slots 14 at one end near the vertical positioning rod 5. The two second slots 14 are perpendicular to the axis connecting line of the horizontal positioning rod 4. A pin 15 is inserted into the inner wall of the first slot 13, and the pin 15 is inserted into one of the second slots 14.

[0020] The working principle of the positioning and setting-out device for bolt hole pre-embedded sleeve construction provided by this utility model is as follows: I. Core Positioning Logic: Construction of X-axis-Y-axis Cartesian Coordinate System The device constructs a rectangular coordinate system with "horizontal bar 1 as the X-axis and vertical bar 2 as the Y-axis". All positioning operations are carried out around this coordinate system. Through the vertical calibration and fixing of the X-axis and Y-axis, and the movement of the positioning bar along the axis, the intersection of the X and Y axes is finally determined to achieve precise positioning. Step 1: Alignment of X-axis and Y-axis perpendicularity and fixing with pin 15 Frame construction and vertical adjustment: Place the horizontal bar 1 as the X-axis and horizontally at the top reference edge of the template; place the vertical bar 2 as the Y-axis and adjust the angle between the vertical bar 2 and the horizontal bar 1 to 90° through the rotational connection between the vertical bar 2 and one end of the horizontal bar 1, so that the X-axis and Y-axis are completely perpendicular, forming the basic frame of the positioning coordinate system. Pin 15 locks verticality: Using the first slot 13 at the end of the vertical positioning rod 5 and the second slot 14 at the end of the horizontal positioning rod 4, insert pin 15 into the first slot 13 and correspondingly into one of the second slots 14. Through the insertion and limiting of pin 15, the 90° vertical relationship between the X-axis and Y-axis is forcibly fixed, preventing the angle between the two axes from shifting during subsequent operations and ensuring the stability of the coordinate system reference. III. Second Step: L-shaped tie rod reinforces the X-axis and Y-axis After the perpendicular relationship between the X-axis and Y-axis is locked by pin 15, the horizontal bar 1 and the vertical bar 2 are firmly fixed on the template by the L-shaped tie rod mechanism to prevent the axis from shifting. Rotating the threaded rod 10 drives the pull rod: The construction worker uses a tool to rotate the hexagonal block 12 at the end of the threaded rod 10, which drives the threaded rod 10 to rotate in the slide groove 8 inside the positioning rod; since the L-shaped pull rod is threadedly connected to the threaded rod 10, the rotation of the threaded rod 10 will be converted into the linear movement of the L-shaped pull rod along the slide groove 8. Anti-slip bonding and fixing: When the L-shaped tie rod is moved to its bottom end and tightly fits against the template surface, the nitrile rubber anti-slip pad at the bottom of the tie rod will form a strong frictional contact with the template, preventing the horizontal bar 1 from sliding along the X-axis and the vertical bar 2 from sliding along the Y-axis. At the same time, the lightweight alloy material of the horizontal bar 1 and the vertical bar 2 ensures reinforcement stability while preventing deformation of the template, further consolidating the fixed position of the XY axis coordinate system. Fourth, the third step: the positioning rod moves along the X / Y axis to determine the construction point. Using the fixed X and Y axes as references, the precise construction point is found by sliding the horizontal positioning rod 4 and the vertical positioning rod 5: Lateral positioning rod 4 moves: The lateral positioning rod 4 slides along the top of the X-axis and aligns with the scale line 6 on the X-axis through the scale pointer 7 at its end to determine the lateral coordinate - for example, adjust the scale pointer 7 to point to the preset "X=50cm" scale to complete the lateral position positioning. Vertical positioning rod 5 moves: The vertical positioning rod 5 slides along the top of the Y-axis and aligns the scale pointer 7 at its end with the scale line 6 on the Y-axis to determine the vertical coordinates. For example, the scale pointer 7 is adjusted to point to the preset "Y=30cm" scale to complete the vertical position positioning. Double-fixed positioning rods: Tighten the fixing bolts 16 at one end of the horizontal positioning rod 4 and the vertical positioning rod 5. The bolts press the contact surfaces between the positioning rods and the X / Y axes to prevent the positioning rods from sliding and lock the X and Y coordinate values.

[0021] Construction point determination: The positioning groove 11 in the middle of the horizontal positioning rod 4 and the vertical positioning rod 5 will form a unique intersection point due to the fixed coordinates. This intersection point is the coincidence point of the X-axis coordinate and the Y-axis coordinate, which is the precise construction point of the bolt hole pre-embedded sleeve. Construction personnel can directly carry out the pre-embedded sleeve installation work based on this point.
