Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to an anchor bolt drilling measurement and positioning device. Background Technology
[0002] As the number of optical cables increases, the size of the optical cable supports along the lines of public transportation facilities such as high-speed railways, subways, and urban utility tunnels also increases. In the usual construction process, the installation of optical cable supports is basically based on the concrete surface for positioning, and the distribution of the internal steel reinforcement is basically ignored. If there are many skewed holes or abandoned holes during the drilling process, the skewed anchor bolt holes do not meet the specifications, and the abandoned holes need to be resealed, resulting in a waste of manpower and resources. On the other hand, separately probing the internal steel reinforcement will make the measurement and positioning process cumbersome and introduce a lot of errors, causing the anchor bolt hole positions on the same straight line to be offset. Utility Model Content
[0003] The purpose of this utility model is to provide an anchor bolt drilling measurement and positioning device to solve the technical problem in the prior art where errors are easily introduced during the drilling of anchor bolt holes for installing optical cable brackets, leading to the displacement of anchor bolt hole positions on the same straight line. The specific technical solution is as follows:
[0004] This utility model provides an anchor bolt drilling measurement and positioning device, including a rebar detector, a pen, a leveling rod, and an elastic element. The rebar detector has an installation hole for the pen to pass through. The rebar detector is installed on the leveling rod, and the pen passes through the installation hole. The elastic element connects the installation hole and the pen. The length of the pen is greater than the thickness of the rebar detector.
[0005] A further improvement of this utility model of anchor bolt drilling measurement and positioning device is that the center of the mounting hole is aligned with the zero mark of the gauge.
[0006] A further improvement of this utility model of anchor bolt drilling measurement and positioning device is that the rebar detector is installed on the measuring rod via a connector.
[0007] A further improvement of this utility model of anchor bolt drilling measurement and positioning device is that the connector is L-shaped, the length of the rebar detector is greater than the width of the measuring rod, the first side of the connector is connected to the side of the rebar detector, and the second side of the connector is connected to the side of the measuring rod.
[0008] A further improvement of this utility model of anchor bolt drilling measurement and positioning device is that the elastic element is a spring, which is wound around the outer periphery of the ink pen, and the top end of the spring is connected to the ink pen, and the bottom end of the spring is connected to the side wall of the mounting hole.
[0009] A further improvement of this utility model of anchor bolt drilling measurement and positioning device is that the top of the ink pen is provided with an ink storage chamber.
[0010] The application of the technical solution of this utility model has the following beneficial effects:
[0011] This utility model of an anchor bolt drilling measurement and positioning device integrates distance measurement, rebar measurement, and position marking through the coordinated installation of a rebar detector, a pen, and a leveling rod.

[0016] Figure 3 This is a schematic diagram showing the usage status of the anchor bolt drilling measurement and positioning device of this utility model.
[0017] The components include: 1. Rebar detector; 2. Mounting hole; 3. Ink storage chamber; 4. Measuring rod; 5. Connector; 6. Zero mark; 7. Ink pen; 8. Spring; 9. Horizontal line; 10. Anchor bolt hole; 11. Rebar mesh. Detailed Implementation
[0018] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] See Figures 1-3As shown, an anchor bolt drilling measurement and positioning device includes a rebar detector 1, a pen 7, a leveling rod 4, and an elastic element. The rebar detector 1 has an installation hole 2 for the pen 7 to pass through. The rebar detector 1 is installed on the leveling rod 4. The pen 7 is inserted into the installation hole 2. The elastic element connects the installation hole 2 and the pen 7. The length of the pen 7 is greater than the thickness of the rebar detector 1.
[0020] Specifically, the measuring rod 4 is an extendable measuring rod with a maximum length of 3m. The rebar detector 1 can use a wall detector of model GMS100-23, with a detection depth of 100mm, which is basically greater than the thickness of the protective layer of the concrete wall, meeting the actual use requirements.
[0021] Preferably, the center of the mounting hole 2 is aligned with the zero mark 6 of the scale 4, which facilitates the measurement of the distance between adjacent ink dots during use, thereby helping to determine the position of the next ink dot.
[0022] Preferably, the rebar detector 1 is installed on the measuring rod 4 via the connector 5, thereby ensuring that the rebar detector 1 is securely installed on the measuring rod 4.
[0023] Preferably, the connector 5 is L-shaped, the length of the rebar detector 1 is greater than the width of the measuring rod 4, the first side of the connector 5 is connected to the side of the rebar detector 1, and the second side of the connector 5 is connected to the side of the measuring rod 4. There are two connectors 5, and the two connectors 5 are located on the two sides of the measuring rod 4 respectively.
[0024] Preferred, such as Figure 2 As shown, the elastic element is a spring 8, which is wound around the outer periphery of the ink pen 7. The top end of the spring 8 is connected to the ink pen 7, and the bottom end of the spring 8 is connected to the side wall of the mounting hole 2. When marking is required, the ink pen 7 is pressed to leave a mark on the wall. The spring 8 then allows the ink pen 7 to automatically spring back, thus preventing the ink pen 7 from leaving unnecessary marks on the wall.
[0025] Preferably, the ink pen 7 has an ink storage chamber 3 at the top, so as to continuously supply ink to the pen tip of the ink pen 7.
[0026] When using, such as Figure 3As shown in the diagram, the grid lines represent the reinforcing mesh 11 inside the wall. First, mark the required drilling height on the wall using ink lines or horizontal lines 9 according to the drawing data. Then, determine the starting anchor bolt position based on the anchor bolt spacing requirements and the actual site conditions. Use the anchor bolt drilling measurement and positioning device to measure and mark each bolt. If the anchor bolt drilling position coincides with the reinforcing bar position, it needs to be shifted slightly along the horizontal line 9 to avoid the internal reinforcing bar. When there is no reinforcing bar under the measured anchor bolt drilling position, press the ink pen 7 on the device to mark it. During the marking process, the leveling rod 4 can be kept parallel to the horizontal line 9 to avoid skewed marking of the anchor bolt holes 10.
[0027] This utility model of an anchor bolt drilling measurement and positioning device integrates distance measurement, rebar measurement, and position marking through the coordinated installation of a rebar detector 1, an ink pen 7, and a leveling rod 4. While measuring the rebar, the leveling rod 4 provides additional distance measurement assistance, solving the problem in existing technologies where errors are easily introduced during the drilling of anchor bolt holes 10 while installing fiber optic cable brackets, leading to positional deviations of the anchor bolt holes 10 on the same straight line. This utility model is simple to operate, improves the measurement method, and compared to existing measurement and positioning methods, does not add any new procedures and eliminates the need for frequent changes of measuring tools during the measurement and construction process.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
