[0030] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0031] like Figure 1-Figure 3 As shown, in an embodiment of the present application, the present application provides a device for measuring the contour line of a building structure, including a positioning body 1, an axis positioning mechanism 2, a contour positioning mechanism 3 and a support frame 5, and each part is described in detail below.

[0032] like Figure 1 As shown, in an embodiment of the present application, the present application provides a device for measuring the contour line of a building structure, comprising:

[0033] The positioning body 1 is used to locate the center of the building structure to be laid out; the cross section of the positioning body 1 is a regular shape, and a scale mark 11 is provided in its length direction;

[0034] The axis positioning mechanism 2 is arranged 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 instrument 21, and the laser beam emitted by the axis positioning laser instrument 21 forms a first laser surface 22, and the first laser surface 22 is coplanar with the cross-sectional center line of the positioning body 1;

[0035] The contour positioning mechanism 3 is movably mounted on the positioning body 1 and can move along the length direction of the positioning body 1; it includes a contour positioning laser instrument 32, the laser beam emitted by the contour positioning laser instrument 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] The support frame 5 is used to fix the positioning body 1 on 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 building structure contour lines 8 that are parallel to each other, each contour line is parallel to the building control axis 9, and the intersection of two vertically intersecting building control axes 9 is the cross-sectional center of the building structure; the working principle of the present invention is: the cross-sectional center of the building structure to be laid out is taken 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 cross-sectional center line 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 cross-sectional center line of the positioning body 1 is coplanar with the building control axis 9; The contour line formed when the second laser surface 33 is projected on the ground is parallel to the side wall of the positioning body 1. When the cross-sectional centerline 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 of the corresponding side length of the building structure. According to the side length of the building structure and the set projection angle, the height at which the control contour positioning mechanism 3 is located on the positioning body 1 can be reversely calculated, and then the contour positioning mechanism 3 is moved to be located at this height, so that 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 the present application can only move in the length direction of the positioning body 1, and will not rotate relative to the positioning body 1, so as to ensure that the contour line projected by the second laser surface 33 is always in a parallel position with the side wall of the positioning body 1. Therefore, the cross-section of the positioning body 1 in the present application is square or rectangular. Preferably, the cross-section of the positioning body 1 is square, and the contour positioning mechanism 3 fits tightly to the positioning body 1, thereby enhancing the accuracy of the measurement.

[0039] Furthermore, if Figure 1 As shown, the contour positioning mechanism 3 includes a positioning cone, and the positioning cone 31 is provided with a through hole and four inclined planes 311; wherein the through hole matches the positioning body 1, and its cross-sectional shape is also square, which can be tightly fitted to the side wall of the positioning body 1 and sleeved on the outside of the positioning body 1; the above-mentioned inclined plane 311 has a set angle with the side wall, and the four inclined planes 311 form a quadrangular pyramid structure, which is arranged at the center of the quadrangular pyramid along the height direction; the contour positioning laser instrument 32 is respectively arranged on the inclined plane 311, and the second laser plane 33 is parallel to the inclined plane 311, ensuring that when the second laser plane is projected on the ground, the contour line formed is parallel to the side wall of the positioning body 1; at this time, the distance between the two relative contour lines is the side length of the cross-sectional shape of the building structure, and the second laser plane 33, the positioning body 1 and the ground are enclosed to form a right triangle, and the side length of the cross-sectional shape of the building structure and the set angle are both known. According to the side length and the angle, the height of the contour positioning mechanism 3 located at the positioning body 1 can be reversely calculated.

[0040] In a preferred embodiment, the 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 length of the side 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, in order 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. When in use, the positioning cone is moved to align its top with the scale mark 11 corresponding to the calculated height, which is easier to operate. Specifically, the positioning cone also includes an extension section 312 disposed at the upper end of the inclined plane 311, and each contour positioning laser instrument 32 is disposed at the same relative position on the inclined platform. The laser emission port of the contour positioning laser instrument 32 faces away from the extension section 312, and the top of the extension section 312 is a flush structure and intersects with the reverse extension line of the second laser surface 33 emitted by the laser emission port.

[0042] The bottom of the positioning cone in the present application is provided with a stop pin 314, 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 is provided with a fixing section 313, and the fixing portion is provided with a transverse threaded hole, and the stop pin 314 is threadedly connected with the transverse threaded hole. By screwing the stop pin 314, the positioning cone can be fixed or released.

[0043] In the present application, the height of the contour positioning mechanism 3 is calculated by reverse calculation through the second laser surface 33, the positioning body 1 and the ground to form a right triangle, so it is necessary to ensure that the positioning body 1 is perpendicular to the ground; in the embodiment of the present application, the side limit device also includes a horizontal mechanism 4, which is used to determine the verticality of the positioning body 1. Specifically, a mounting seat 12 is vertically provided on the upper part of the positioning body 1, and the horizontal mechanism 4 uses a level, which is fixed to the upper surface of the mounting seat 12, so that the operator can observe at any time and adjust the state of the positioning body 1 according to the level.

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

[0045] Furthermore, the axis positioning mechanism 2 is arranged at the top of the positioning body 1, and the mounting seat 12 is arranged close to the axis positioning mechanism 2. The positioning body 1 below the mounting seat 12 has sufficient length remaining to meet the height movement requirements of the contour positioning structure; at the same time, the bottom end of the positioning body 1 in the present application is pointed, which is convenient for placing the positioning body 1 in the cross-sectional center of the building structure to be laid out, ensuring accurate positioning.

[0046] Furthermore, the support frame 5 is a retractable triangular support structure. By adjusting the length of the support frame 5, the verticality of the positioning body 1 can be adjusted, and at the same time, good support is provided for the positioning body 1 to be fixed on the ground to ensure accurate measurement.

[0047] The present application also proposes a method for measuring the contour line of a building structure. By using the measuring device for the contour line of a building structure proposed in the first aspect of the present application, efficient and accurate measurement of the contour line of the building structure is achieved, which is explained below through specific embodiments.

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

[0053] S3.

[0056] S5, turning on the contour positioning laser device 32 to project the contour line of the building structure;

[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, and the height of the contour positioning mechanism 3 is half of the side length of the building structure. Since the long side and the short side of the rectangle are inconsistent, the long side and the short side need to be measured in sequence, and the measurement order of the two 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 the short side.

[0068] S5, turning on the contour positioning laser device 32 to project two opposite contour lines of the building structure;

[0069] Since the cross-section of the building structure to be laid out is a rectangle, two relative contour positioning lasers 32 are simultaneously turned on in this step to project and form two contour lines corresponding to the two long sides or short sides of the cross-section of the building structure.
