[0003] However, when assembling the steel beam chords and web members, the measurement accuracy of the steel ruler is low and the measurement is not convenient enough, resulting in deviations in the length and width of each truss section compared to the envisioned target size after welding.

[0028] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0030] Reference Figures 1 to 5 As shown, this embodiment provides a total station-based detection device, comprising a total station and four detection assemblies 1. A truss 2 has four corners, each of which is connected to a detection assembly 1. The total station and the four detection assemblies 1 work together to measure the three-dimensional coordinates of the four corners. The detection assembly 1 includes a reflector 3 and a clamping structure, which are detachably connected to the truss 2 via the clamping structure. In a specific implementation, the reflector 3 may include a plate body and reflective stickers affixed to the plate body.

[0031] The detection device based on the total station provided in this embodiment, when in use, the reflector 3 is clamped at the measurement points corresponding to the top corners of the truss 2, and the total station and the reflector 3 cooperate to measure the three-dimensional coordinates of the four measurement points. By providing reflectors 3 at the four top corners of the truss 2, the three-dimensional coordinates of the four top corners can be obtained, and the measured data is used to automatically measure the length L of the steel beams on both sides of the truss 2 and the distance D between the two steel beams through calculation or in cooperation with programming algorithms. The steel beams on both sides of the truss 2 are the upper chord and the lower chord generally referred to in the art, and the steel beam can be an I-beam. The reflector 3 is detachably connected to the truss 2 through a clamping structure to detect the lengths of multiple sections of the truss 2.

[0032] The detection device based on the total station is convenient, fast and accurate in detection, making the error between the distance D between the upper chord and the lower chord of the truss 2 and the target distance small, and the connection difficulty low and the deformation amount small when adjacent two sections of the truss 2 are spliced. Moreover, the error between the lengths L of the upper chord and the lower chord of the truss 2 and the target length is small, making the assembly difficulty low and the deformation amount small when multiple sections of the truss 2 are assembled. The speed and quality of the splicing of the truss 2 are improved.

[0033] In some embodiments, as Figures 2 to 4 shown, the clamping structure includes a bottom plate 4 connected to the reflector 3. A slot is provided on the bottom plate 4. The truss 2 includes a steel beam, and one end of the wing plate 21 of the steel beam is inserted into the slot. The wing plate 21 of the steel beam is in interference fit with the slot. The clamping structure is simple and convenient to implement in the construction working condition. The reflector 3 can be welded to the bottom plate 4. The reflector 3 can be a plate body of the same material as the bottom plate 4, and a reflective sticker can be pasted on the plate body, with low cost and easy to implement.

[0034] In some embodiments, along the thickness direction of the bottom plate 4, that is, the height direction of the steel beam, the slot on the bottom plate 4 penetrates through the bottom plate 4. The slot penetrating through the bottom plate 4 is easy to process and form. Of course, the projection shape of the slot in the thickness direction of the bottom plate 4 can be an inverted "U", that is, the slot has a bottom wall (not shown in the figure) in the thickness direction of the bottom plate 4. When the bottom plate 4 is inserted into one end of the wing plate 21, the bottom wall abuts against the top surface of the wing plate 21. One end of the wing plate 21 along its length direction has a third end face 213, and the third end face 213 abuts against the side wall of the slot. The wing plate 21 has opposite first face 211 and second face 212 along its thickness direction, and the first face 211 and the second face 212 abut against the two side walls of the slot. The side wall and the bottom wall are both inner walls of the slot, and the three side walls and the bottom wall of the slot abut against the four sides (upper side, front side and left and right sides) of the wing plate 21 respectively, increasing the connection strength between the bottom plate 4 and the wing plate 21 and making the connection between the bottom plate 4 and the wing plate 21 more stable.

[0035] In some embodiments, the clamping structure further includes a first movable portion 5 connected to the bottom plate 4. The first movable portion 5 can move closer to or farther from the wing plate 21. The wing plate 21 has a first surface 211 and a second surface 212 opposite to each other along its thickness direction. The wing plate 21 has a third end surface 213 at one end along its length direction. The state when the clamping structure clamps the wing plate 21 is a clamping state. Figure 2 and Figure 3 As shown, in the clamped state, the first surface 211 and the third end surface 213 both abut the inner wall of the slot, while the second surface 212 abuts the first movable portion 5. At this point, if the slot and the wing plate 21 form an interference fit, the second surface 212 also abuts the inner wall of the slot. Alternatively, the slot and the wing plate 21 can form a clearance fit—that is, if the slot width is greater than the thickness of the wing plate 21, the wing plate 21 and the clamping structure are more easily disassembled, and the clamping structure is adaptable to wing plates 21 of varying thicknesses.

[0036] In a specific implementation, the first movable portion 5 can be a first screw, with a first threaded hole formed in the base plate 4, and the first screw and the first threaded hole forming a threaded engagement. Alternatively, a first nut is connected to the base plate 4, and the first movable portion 5 is a first screw, with the first screw and the first nut forming a bolted connection pair. The first nut can be directly welded to the base plate 4, and the first screw and the nut can cooperate to move the first screw closer to, or further away from, the wing plate 21. The screw and nut achieve movement of the first movable portion 5, making it easy to implement on-site, cost-effective, and practical.

[0037] In some embodiments, as Figure 2 and Figure 3 As shown, the base plate 4 is fixedly connected to the reflector 3. The clamping structure further includes a second movable portion 6 connected to the base plate 4. The second movable portion 6 can move toward the third end surface 213 until it abuts against the third end surface 213, further strengthening the connection strength between the clamping structure and the wing plate 21. The base plate 4 and the reflector 3 can be fixedly connected by welding, bonding, or integral molding.

[0038] In some embodiments, as Figure 5 As shown, the reflector 3 is movably connected to the base plate 4. The clamping structure also includes a second movable portion 6 connected to the base plate 4. The second movable portion 6 can move toward the third end surface 213 until it abuts the reflector 3. At this point, the reflector 3 is clamped between the second movable portion 6 and the third end surface 213. The position of the reflector 3 relative to the wing plate 21 along the thickness direction of the wing plate 21 is adjustable. Because the ends of the wing plate 21 are inclined, the longest end of the wing plate 21 aligns with the middle of the reflector 3 (the location where the reflective tape is affixed, preferably the center of the tape). This is the most accurate measurement of the steel beam length, so the position of the reflector 3 needs to be adjusted. The reflector 3 is clamped between the second movable portion 6 and the third end surface 213 to maintain a vertical position relative to the base plate 4.

[0039] In a specific implementation, a second nut is connected to the base plate 4, and the second movable portion 6 is a second screw. The second screw and the second nut form a bolted connection pair. When the reflector 3 is fixedly connected to the base plate 4, the second nut can be located above or below the base plate 4. When the reflector 3 is movably connected to the base plate 4, the second nut is located above the base plate 4. The second screw and the second nut form a bolted connection pair, which is easy to implement on site, low-cost, and practical.

[0040] In some embodiments, the wing plate 21 is clearance-matched with the slot, that is, the width of the slot is greater than the thickness of the wing plate 21 , and the wing plate 21 and the clamping structure are easier to disassemble. At the same time, the clamping structure is adapted to wing plates 21 of different thicknesses.

[0041] In some embodiments, one end of the first screw toward the wing plate 21 extends radially along the first screw to form a first limiting portion, and the cross-sectional area of the first limiting portion is larger than the cross-sectional area of the first threaded hole or the threaded hole of the first nut. One end of the second screw toward the wing plate 21 extends radially along the second screw to form a second limiting portion, and the cross-sectional area of the second limiting portion is larger than the cross-sectional area of the threaded hole of the second nut. The first limiting portion / the second limiting portion can increase the connection area when the first screw / the second screw abuts the wing plate 21, so as to make the connection between the clamping structure and the wing plate 21 more stable; at the same time, the first limiting portion / the second limiting portion can also prevent the first screw / the second screw from being separated from the first nut / the second nut, thereby preventing the first screw and the second screw from being lost during practical use of the detection device based on the total station.
