Description

Technical Field

[0001] The present application relates to the field of construction engineering measurement, and in particular to a measurement device for construction engineering. Background Art

[0002] Construction projects refer to the engineering entities formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting wiring, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that meet people's needs for production, living, learning, and public activities. Surveying equipment is required before conducting field surveys and building to ensure accuracy during construction.

[0003] Common existing construction engineering measurement tools include steel tape measures and laser rangefinders. Steel tape measures can quickly measure beams and columns in building construction, but steel tape measures may bend or stretch, making it difficult to adhere to the surface of the measured object during measurement. Therefore, the accuracy of the measured data is limited. Compared with steel tape measures, laser rangefinders have faster measurement speeds and higher accuracy and can perform non-contact measurement. However, laser rangefinders require power or battery support. When the power is too low or exhausted, the measurement data will be inaccurate or unusable. Whether it is a steel tape measure or a laser rangefinder, only one of the length, width and height of the beam and column can be measured at a time. If all the length, width and height data need to be measured, the measuring tool needs to be moved multiple times for multiple measurements, which has low measurement efficiency. In order to solve the above problems, a measurement device for construction engineering is proposed.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application discloses a measuring device for construction engineering. Figure 1-3 A measuring device for construction engineering includes a measuring frame 1 for measuring construction engineering, the measuring frame 1 being provided with two relatively arranged movable scales 10 and a driving assembly for driving the two movable scales 10 to move toward or away from each other simultaneously on the measuring frame 1, the two movable scales 10 each being provided with a slide groove 11 for sliding an extension scale 12, the sides where the two movable scales 10 approach each other being flush with the sides where the two extension scales 12 approach each other, a height measuring assembly being further provided at the bottom of the measuring frame 1, and the movable scales 10 being provided with a distance measuring plate 8 and a distance meter 9 for measuring the distance between the two movable scales 10;

[0021] It should be noted that the sides of the two movable rulers 10 that are close to each other are flush with the sides of the two extension rulers 12 that are close to each other, so that the relative distance between the two extension rulers 12 is always equal to the relative distance between the two movable rulers 10, thereby maintaining the consistency and accuracy of the measured data;

[0022] It should be further explained that the function and model of the rangefinder 9 can be referred to the GLM 30-23 laser rangefinder;

[0023] By adopting the above technical solution, when in use, the measuring frame 1 is placed against one side of the beam to be measured, the driving assembly is shaken to make the two movable rulers 10 approach and fit the side of the beam to be measured, the rangefinder 9 is started to measure the distance between the ranging plate 8, that is, the distance between the two movable rulers 10, the extension ruler 12 is pulled until one end of the extension ruler 12 is flush with the side of the beam to be measured away from the measuring frame 1, and then the height measurement assembly is triggered to read the measurement data of the length, width and height of the beam in sequence.

[0024] Reference Figure 1The driving assembly includes a guide groove 2, a bidirectional screw rod 3, a rocker 4, and a stop plate 5. The guide groove 2 is opened on one side of the measuring frame 1. The bidirectional screw rod 3 rotates between the two sides of the measuring frame 1. One side of the bidirectional screw rod 3 passes through the measuring frame 1 and is fixed to the rocker 4. The end of the moving ruler 10 away from the extension ruler 12 slides in the guide groove 2. The moving ruler 10 is threadedly connected to the bidirectional screw rod 3. The stop plate 5 is fixed to the middle section of one side of the measuring frame 1. The bidirectional screw rod 3 and the stop plate 5 are clearance-matched. The side of the stop plate 5 away from the measuring frame 1 is flush with the initial scale of the moving ruler 10.

[0025] It should be noted that the bidirectional screw rod 3 is divided into a right-hand thread and a left-hand thread, and the two movable scales 10 are respectively connected to the left-hand thread and the right-hand thread, so the two movable scales 10 will move closer or farther away at the same time as the bidirectional screw rod 3 rotates;

[0026] It should be further explained that, during measurement, the side of the abutment plate 5 away from the measuring frame 1 is in contact with the side of the beam to be measured, which can maintain the stability and balance of the measuring frame 1, and the side of the abutment plate 5 away from the measuring frame 1 is flush with the initial scale of the movable scale 10, which can also ensure the accuracy of the measurement data of the movable scale 10;

[0027] By adopting the above technical solution, during measurement, the rocker 4 is shaken to rotate the bidirectional screw 3, and under the guidance of the guide groove 2, the two movable rulers 10 are moved closer to each other until they are in contact with the side of the beam to be measured.

[0028] Reference Figure 1 , a fixed scale 6 is provided on the top of the measuring frame 1, and a reading plate 7 is provided on the top of the two movable scales 10. A distance measuring plate 8 is fixed on one of the reading plates 7, and a distance meter 9 is fixed on the other reading plate 7. The distance measuring plate 8 and the distance meter 9 match, and the two reading plates 7 slide on the fixed scale 6;

[0029] By adopting the above technical solution, when the two movable scales 10 are moved to fit the side of the beam to be measured, the distance between the two movable scales 10 is measured by the rangefinder 9. At the same time, the reading board 7 also corresponds to the value on the fixed scale 6. The data measured by the rangefinder 9 can be aligned and corrected. When the rangefinder 9 is low on power or fails, the value on the fixed scale 6 can also be used as a reference.

[0030] Reference Figure 2 、 3The height measuring assembly includes a rotating groove 13, a support shaft 14, a coil spring 15, a pull rope 16, a slider 17, and a counterweight 18. The rotating groove 13 is opened at the bottom of the measuring frame 1, and the support shaft 14 is fixed on the inner wall of the rotating groove 13. There are two coil springs 15 and they are symmetrically arranged at both ends of the support shaft 14. The pull rope 16 is respectively wound on the two coil springs 15, and one end of the two pull ropes 16 is fixed to the two coil springs 15 respectively. The other ends of the two pull ropes 16 are fixed to the slider 17 at the same time. The slider 17 is inserted into the counterweight 18. A threaded hole for a limit pin 20 to be threaded through is opened on one side of the measuring frame 1. One end of the limit pin 20 extends through the threaded hole to the through hole opened on one side of the counterweight 18.

[0031] It should be noted that the pull rope 16 is also provided with a scale (not shown in the figure). The two sets of pull ropes 16 can ensure the smooth fall of the counterweight 18, thereby ensuring the accuracy of the vertical distance measurement;

[0032] By adopting the above technical solution, when the two movable rulers 10 move to fit in with the side of the beam to be measured, the limit pin 20 is turned to cancel the limit on the counterweight 18. Under the action of gravity, the counterweight 18 will pull the rope 16 down vertically to fit the ground. The height data of the beam to be measured can be obtained by reading the scale on the rope 16. After the measurement is completed, the slider 17 is pulled away from the counterweight 18. Under the winding action of the coil spring 15, the rope 16 is wound into the rotating groove 13, and the slider 17 is also retracted into the rotating groove 13.

[0033] Reference Figure 3 , guide plates 19 are provided on both sides of the rotating groove 13, and one end of the two pull ropes 16 passes through the guide plates 19 and is fixed to the slider 17;

[0034] By adopting the above technical solution, the guide plate 19 is used to guide the position of the pull rope 16 when it is wound and keep the pull rope 16 stable when it is wound.
