[0002] Currently, the cross-sectional shapes of columns or column foundations in building structures are mostly designed as square or rectangular. When measuring and laying out these structures, a total station is usually used to measure and lay out the intersection points of each axis, and then the intersection points are connected to form the axis. Subsequently, the structural outline is laid out using a square and a measuring tape as a reference line for the installation of structural reinforcement and formwork. However, this method of laying out the structural outline is not only cumbersome, labor-intensive, and time-consuming, but also requires multiple measurements with a measuring tape and square, which increases the cumulative error and easily leads to phenomena such as layout eccentricity and unevenness, seriously affecting the measurement accuracy and construction progress.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0031] like Figures 1-3 As shown in the embodiments of this application, this application provides a measuring device for the outline of a building structure, including a positioning body 1, an axis positioning mechanism 2, an outline positioning mechanism 3, and a support frame 5. The following is a detailed description of each part.

[0032] like Figure 1 As shown in the embodiments of this application, this application provides a measuring device for the outline of a building structure, including:

[0033] Positioning body 1 is used to locate the center of the building structure to be laid out; the cross-section of positioning body 1 is a regular shape, and its length direction is marked with scale marks 11;

[0034] An axis positioning mechanism 2 is disposed on the positioning body 1 and is used to determine the orientation of the positioning body 1. The axis positioning mechanism 2 includes an axis positioning laser 21. The laser beam emitted by the axis positioning laser 21 forms a first laser surface 22, and the first laser surface 22 is coplanar with the center line of the cross section of the positioning body 1.

[0035] The contour positioning mechanism 3 is movably sleeved on the positioning body 1 and can move along the length direction of the positioning body 1; it includes a contour positioning laser 32, the laser beam emitted by the contour positioning laser 32 forms a second laser surface 33, and the second laser surface 33 is projected onto the ground at a set angle to form a contour line parallel to the side wall of the positioning body 1.

[0036] Support frame 5 is used to fix the positioning body 1 to the ground.

[0037] like Figure 2 As shown, when the cross-section of the building structure is square or rectangular, the building structure includes four parallel building structure outlines 8, each outline being parallel to the building control axis 9. The intersection of two perpendicularly intersecting building control axes 9 is the center of the building structure's cross-section. The working principle of this utility model is as follows: the center of the cross-section of the building structure to be laid out is used as the positioning point 6, and the positioning body 1 is erected at the positioning point 6. Since the first laser surface 22 emitted by the axis positioning mechanism 2 is coplanar with the center line of the cross-section of the positioning body 1, the orientation of the positioning body 1 can be adjusted by adjusting the projection angle of the first laser surface 22, so that the center line of the cross-section of the positioning body 1 is coplanar with the building control axis 9. Because the contour line formed by the second laser surface 33 when it is projected onto the ground is parallel to the side wall of the positioning body 1, when the center line of the cross section of the positioning body 1 is coplanar with the building control axis 9, the contour line projected by the second laser surface 33 is also parallel to the actual contour line of the building structure. It can be understood that the distance between the contour line projected by the second laser surface 33 and the positioning point 6 is half the side length of the corresponding building structure. Based on the side length of the building structure and the set projection angle, the height of the control contour positioning mechanism 3 on the positioning body 1 can be calculated. Then, by moving the contour positioning mechanism 3 to be at that height, the contour line projected by the second laser surface 33 coincides with the actual contour line of the building structure.

[0038] The contour positioning mechanism 3 in this application can only move along the length of the positioning body 1 without rotating relative to the positioning body 1, so as to ensure that the contour line projected by the second laser surface 33 is always parallel to the side wall of the positioning body 1. Therefore, the cross section of the positioning body 1 in this application is square or rectangular, preferably square. The contour positioning mechanism 3 fits tightly against the positioning body 1, which enhances the accuracy of the measurement.

[0039] Furthermore, such as Figure 1 As shown, the contour positioning mechanism 3 includes a positioning cone 31, which has a through hole and four inclined planes 311. The through hole matches the positioning body 1 and has a square cross-sectional shape, allowing it to fit tightly against the side wall of the positioning body 1 and be fitted onto the outside of the positioning body 1. The inclined planes 311 have a set angle with the side wall, and the four inclined planes 311 form a quadrangular truncated pyramid structure, which is set at the center of the quadrangular truncated pyramid along the height direction. The contour positioning laser 32 is respectively set on the inclined planes 311, and the second laser surface 33 is parallel to the inclined planes 311, ensuring that when the second laser surface is projected onto the ground, the resulting contour line is parallel to the side wall of the positioning body 1. At this time, the distance between the two opposite contour lines is the side length of the cross-sectional shape of the building structure. The second laser surface 33, the positioning body 1, and the ground form a right triangle. Since the side length of the cross-sectional shape of the building structure and the set angle are known, the height of the contour positioning mechanism 3 on the positioning body 1 can be calculated based on the side length and the angle.

[0040] In a preferred embodiment, the included angle is set to 45 degrees, so that the second laser surface 33, the positioning body 1 and the ground form an isosceles right triangle. The height of the contour positioning mechanism 3 at the positioning body 1 is half the side length of the cross-sectional shape of the building structure. This makes it easier to calculate the height of the contour positioning mechanism 3 when measuring the contour lines of building structures with different cross-sectional shapes, simplifies the calculation process and ensures measurement accuracy.

[0041] Furthermore, to facilitate accurate adjustment of the contour positioning mechanism 3 to the calculated height, the intersection point of the reverse extension line of the second laser surface 33 is flush with the top of the positioning cone. In use, simply move the positioning cone until its top aligns with the scale mark 11 corresponding to the calculated height, making operation even simpler. Specifically, the positioning cone also includes an extension section 312 located on the upper end of the inclined plane 311. Each contour positioning laser 32 is positioned in the same relative position on the inclined platform. The laser emission port of the contour positioning laser 32 faces away from the extension section 312. The top of the extension section 312 is flush and intersects with the reverse extension line of the second laser surface 33 emitted from the laser emission port.

[0042] The positioning cone in this application has a limiting pin 314 at its bottom, which is used to fix the positioning cone to the positioning body 1 after the height adjustment is completed, so as to ensure that the contour positioning mechanism 3 does not move during use and affect the accuracy of the measurement. Specifically, the bottom of the positioning cone has a fixing section 313, and the fixing part has a transverse threaded hole. The limiting pin 314 is threadedly connected to the transverse threaded hole. By turning the limiting pin 314, the positioning cone can be fixed or unfixed.

[0043] In this application, the height of the contour positioning mechanism 3 is calculated by inversely using a right-angled triangle formed by the second laser surface 33, the positioning body 1, and the ground. Therefore, it is necessary to ensure that the positioning body 1 is perpendicular to the ground. In this embodiment, the lateral limiting device also includes a horizontal mechanism 4 for determining the verticality of the positioning body 1. Specifically, a mounting base 12 is vertically provided on the upper part of the positioning body 1, and the horizontal mechanism 4 uses a level. The level is fixed to the upper surface of the mounting base 12, which allows the operator to observe and adjust the state of the positioning body 1 according to the level.

[0044] In one specific embodiment, the mounting base 12 is provided with a power supply for supplying power to the axis positioning laser 21 and the contour positioning laser 32.

[0045] Furthermore, the axis positioning mechanism 2 is located at the top of the positioning body 1, and the mounting base 12 is located close to the axis positioning mechanism 2. The positioning body 1 below the mounting base 12 has sufficient length to meet the height movement requirements of the contour positioning structure. At the same time, the bottom end of the positioning body 1 in this application is pointed, which makes it easy to place the positioning body 1 at the center of the cross section of the building structure to be laid out, ensuring accurate positioning.

[0046] Furthermore, the support frame 5 is a telescopic triangular support structure. By adjusting the length of the support frame 5, the verticality of the positioning body 1 can be adjusted, while providing good support for the positioning body 1 to fix it on the ground, so as to ensure accurate measurement.

[0047] The measuring device for building structure outlines proposed in this application enables efficient and accurate measurement of building structure outlines, which will be described below through specific embodiments.

[0050] S1. Set the center point of the building structure to be laid out as the positioning point 6, and set the center point of another building structure on the same building control axis 9 as the reference point 7.

[0051] In this application, the center point of the building structure to be laid out is the intersection of two perpendicular building control axes 9, which is also the center of the building structure section; similarly, the reference point 7 is the center of the section of another building structure, which is located on one of the two building control axes 9 of the building structure to be laid out.

[0052] S2. Place the positioning body 1 at the positioning point 6, so that the tip of the positioning body 1 is aligned with the positioning point 6.

[0053] S3. Turn on the axis positioning laser instrument 21, adjust the angle and verticality of the positioning body 1 so that the positioning body 1 is in a vertical state and the first laser surface 22 covers the reference point 7; at this time, it can be determined that the center line of the section of the positioning body 1 is parallel to the building control axis 9, and the angle of the positioning body 1 is correct.

[0054] S4. Adjust the height of the contour positioning mechanism 3 according to the cross-sectional dimensions of the building structure to be laid out;

[0055] In this embodiment, the angle between the inclined surface of the contour positioning mechanism 3 and the side wall of the positioning body 1 is 45 degrees, and the height of the contour positioning mechanism 3 is half the side length of the building structure. The top of the positioning cone is moved to align with the corresponding scale mark 11.

[0056] S5. Turn on the contour positioning laser 32 to project the outline of the building structure;

[0057] Since the cross-sectional shape of the building structure to be laid out is square, four contour positioning lasers 32 are turned on simultaneously in this step to project and form four contour lines.

[0058] S6. Use the ink line to draw the outline.

[0059] Draw intersecting ink lines along the four outlines formed by the projection to form the outline of the building structure 8.

[0061] A method for measuring the outline of a building structure, using the measuring device for measuring the outline of a building structure with a rectangular cross-section as proposed in this application, includes the following steps:

[0062] S1. Set the center point of the building structure to be laid out as the positioning point 6, and set the center point of another building structure on the same building control axis 9 as the reference point 7.

[0063] In this application, the center point of the building structure to be laid out is the intersection of two perpendicular building control axes 9, which is also the center of the building structure section; similarly, the reference point 7 is the center of the section of another building structure, which is located on one of the two building control axes 9 of the building structure to be laid out.

[0064] S2. Place the positioning body 1 at the positioning point 6, so that the tip of the positioning body 1 is aligned with the positioning point 6.

[0065] S3. Turn on the axis positioning laser instrument 21, adjust the angle and verticality of the positioning body 1 so that the positioning body 1 is in a vertical state and the first laser surface 22 covers the reference point 7; at this time, it can be determined that the center line of the section of the positioning body 1 is parallel to the building control axis 9, and the angle of the positioning body 1 is correct.

[0066] S4. Adjust the height of the contour positioning mechanism 3 according to the cross-sectional dimensions of the building structure to be laid out;

[0067] In this embodiment, the angle between the inclined surface of the contour positioning mechanism 3 and the side wall of the positioning body 1 is 45 degrees. The height of the contour positioning mechanism 3 is half the side length of the building structure. Since the long side and short side of the rectangle are not the same, the long side and short side need to be measured in sequence. The order of measurement is not restricted here. In this step, the top of the positioning cone is moved to align with the scale mark 11 corresponding to the long side or short side.

[0068] S5. Turn on the contour positioning laser 32 to project two opposing contour lines of the building structure.

[0069] Since the cross-sectional shape of the building structure to be laid out is rectangular, two opposing contour positioning lasers 32 are turned on simultaneously in this step to project and form two contour lines, which correspond to the two long or short sides of the building structure cross-section.

[0070] S6. Use the ink line to draw two outlines.

[0071] Draw intersecting ink lines along the two outlines formed by the projection to form two architectural outlines 8;

[0072] S7. Adjust the height of the contour positioning mechanism 3 according to the side lengths of the other two sides of the building structure section to be laid out.

[0073] In this step, simply move the top of the positioning cone until it aligns with the scale mark 11 corresponding to the other two long or short sides.

[0074] S8. Turn on the contour positioning laser 32 to project two opposing contour lines of the building structure.

[0075] Simultaneously, turning on the other two relative contour positioning lasers 32 will project and form two other contour lines, which correspond to the other two long or short sides of the building structure section.

[0076] S9. Use the ink line to draw two outlines.

It is applicable to the measurement of outlines of building structures with various cross-sectional shapes and specifications. Each building structure only needs to be set up and positioned once to quickly complete the measurement, avoiding the cumulative errors caused by surveyors using measuring tapes and squares to find the square and measure the distance multiple times. It simplifies the measurement steps, reduces the labor intensity of surveyors, and significantly improves measurement efficiency and accuracy, which is conducive to saving construction time and reducing construction costs.
