DETAILED DESCRIPTION

[0048] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0049] In addition, the accompanying drawings are only schematic illustrations of the embodiments of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated descriptions will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0050] In this example implementation, a method for measuring the spatial position of the anchor point of a steel anchor beam is first provided. Figure 1 As shown in , the method may include:

[0051] Step S101: Determine the position of the anchor point 610 of the anchor box 600.

[0052] Step S102: Determine the horizontal plane where the anchor point 610 is located according to the position of the anchor point 610, and return the transverse baseline 400 on the bottom plate of the anchor beam to the horizontal plane where the anchor point 610 is located, and measure the actual distance between the anchor point 610 and the transverse baseline on the horizontal plane.

[0053] Step S103: Return the longitudinal baseline on the bottom plate to the top plate, and then use the measuring rod 300 to measure the distance between the two anchor points 610 on both sides of the web to obtain the actual distance between the anchor point 610 on one side of the web to the longitudinal baseline on the top plate.

[0054] Step S104: measuring the actual distance of the anchor point 610 in the height direction.

[0055] Through the above method, on the one hand, the horizontal plane where the anchor point 610 is located is determined by using the position of the anchor point 610, and the actual distance between the anchor point 610 and the horizontal baseline on the horizontal plane is measured; on the other hand, the measuring rod 300 is designed to measure the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate. In addition, the actual distance of the anchor point 610 in the height direction is measured. The present disclosure decomposes the spatial angle of the anchor point 610 of the anchor box 600 in different directions, and converts the spatial angle of the anchor point 610 that is difficult to measure directly into a straight-line distance that is easy to measure. The measuring rod 300 designed at the same time can quickly realize the measurement of the spatial position of the anchor point 610, reduce costs, and improve production efficiency.

[0056] Next, we will refer to Figures 1 to 11 The various parts of the method for measuring the spatial position of the anchor point 610 of the steel anchor beam in this exemplary embodiment are described in more detail.

[0057] In step S101, when determining the position of the anchor point 610 of the anchor box 600, it is implemented by the following implementation:

[0058] In one embodiment, Figure 2 and Figure 3 As shown, a circular plate 100 is made of thin iron sheet, and the center of the circular plate 100 is marked, and notches 101 are cut at two mutually perpendicular diameter positions on the circular plate 100. The two notches 101 on the same diameter are symmetrically arranged, so the two notches 101 on the same diameter also form alignment notches 101.

[0059] In one embodiment, two mutually perpendicular diameter extension positioning lines are then drawn on the anchor plate of the anchor box 600 of the steel anchor beam, and each notch 101 of the circular plate 100 is overlapped with the corresponding positioning line on the anchor plate, and the position of the anchor point 610 of the anchor box 600 is determined by the center of the circular plate 100.

[0060] In step S102, the horizontal plane where the anchor point 610 is located is determined according to the position of the anchor point 610, and the transverse baseline 400 on the bottom plate of the anchor beam is returned to the horizontal plane where the anchor point 610 is located, and the actual distance between the anchor point 610 and the transverse baseline on the horizontal plane is measured, including the following implementations:

[0061] In one embodiment, Figure 4 , Figure 5 and Figure 6As shown, an L-shaped bracket 200 is designed and manufactured, and the L-shaped bracket 200 includes a horizontal portion 210 and a vertical portion 220 vertically connected to the horizontal portion 210, and the horizontal portion 210 and the vertical portion 220 are connected by an inclined rod 230. Among them, the upper plane of the L-shaped bracket is located on the horizontal portion 210. The horizontal portion 210 can be a horizontal plate, and the vertical portion 220 can be a vertical plate.

[0062] In one embodiment, after the horizontal plane where the anchor point 610 is located is determined according to the position of the anchor point 610, the L-shaped bracket 200 is fixed to the web so that the upper plane of the L-shaped bracket 200 is located on the horizontal plane where the anchor point 610 is located. When the L-shaped bracket 200 is fixed to the web, the L-shaped bracket 200 is fixed to the web by spot welding, so that the upper plane of the L-shaped bracket 200 is located on the horizontal plane where the anchor point 610 is located.

[0063] In one embodiment, the transverse baseline 400 on the bottom plate is then returned to the upper plane of the L-shaped bracket 200, and the actual distance between the anchor point 610 and the transverse baseline on the upper plane of the L-shaped bracket 200 is measured. The actual distance between the anchor point 610 and the transverse baseline on the upper plane of the L-shaped bracket 200 can be measured by a measuring tool such as a tape measure.

[0064] In one embodiment, after measuring the actual distance between the anchor point 610 and the horizontal baseline on the horizontal plane, the method further includes:

[0065] Based on the theoretical distance between the anchor point 610 and the transverse baseline on the upper plane of the L-shaped bracket 200, and the actual distance between the anchor point 610 and the transverse baseline on the upper plane of the L-shaped bracket 200, the distance deviation of the anchor point 610 relative to the transverse baseline on the L-shaped bracket 200 is calculated.

[0066] It should be understood that after measuring the actual distance between the anchor point 610 and the transverse baseline on the horizontal plane, it is also necessary to calculate the distance deviation of the anchor point 610 relative to the transverse baseline on the L-shaped bracket 200. Specifically, the absolute value of the difference between the theoretical distance between the anchor point 610 and the transverse baseline on the upper plane of the L-shaped bracket 200 and the actual distance between the anchor point 610 and the transverse baseline on the upper plane of the L-shaped bracket 200 can be calculated to calculate the distance deviation of the anchor point 610 relative to the transverse baseline on the L-shaped bracket 200.

[0067] In step S103, the longitudinal baseline on the bottom plate is returned to the top plate, and then the distance between the two anchor points 610 on both sides of the web is measured by using the measuring rod 300 to obtain the actual distance between the anchor point 610 on one side of the web plate and the longitudinal baseline on the top plate, including the following implementations:

[0068] In one embodiment, the measuring rod 300 includes: 2 positioning pins 320, a long rod 310 and 2 sleeves 330;

[0069] The two positioning pins 320 are respectively disposed on the long rod 310 , and each positioning pin 320 is fixed by a sleeve 330 .

[0070] It should be understood that in the process of measuring the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate, it is necessary to design and manufacture the measuring rod 300, such as Figure 7 , Figure 8 and Fig. 9 As shown, the measuring rod 300 includes two positioning pins 320, a long rod 310 and two sleeves 330. Each sleeve 330 is used to fix the corresponding positioning pin 320 on the long rod 310, ensuring that the sleeve 330, the positioning pin 320 and the long rod 310 are in the same plane, and finally fixed by a locking screw 340. Among them, the positions of the two positioning pins 320 on the long rod 310 can be set according to the distance between the two anchor points 610.

[0071] In one embodiment, the long rod 310 is placed on the web, and the length of each positioning pin 320 is adjusted so that the tip of each positioning pin 320 contacts the corresponding anchor point 610 respectively;

[0072] Then measure the length of the long rod 310 between the two positioning pins 320, that is, obtain the distance between the anchor points 610 on both sides of the web;

[0073] Thus, the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate is obtained.

[0074] It is important to understand that Fig.10 and Fig.11 As shown, first, place the long rod 310 on the belly plate, and adjust the length of the positioning pin 320 according to the position of the anchor point 610 and the height of the belly plate to ensure that the tip of each positioning pin 320 can smoothly contact the corresponding anchor point 610, and at the same time, the line connecting the tips of the two positioning pins 320 is parallel to the long rod 310.

[0075] Then, adjust the position of the sleeve 330 so that the distance between the tips of the two positioning pins 320, that is, the length of the long rod 310 between the two positioning pins 320, is equal to the distance between the anchor points 610 on both sides of the web. After adjusting the position of the sleeve 330, tighten the locking screw 340 to fix the sleeve 330.

[0076] Since the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate is equal to half of the distance between the anchor points 610 on both sides of the web, after measuring the distance between the anchor points 610 on both sides of the web, the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate can also be calculated.

[0077] It should also be noted that after the positions of the anchor points 610 of the anchor boxes 600 on both sides of the longitudinal baseline 500 on the bottom plate are confirmed, the longitudinal baseline is returned to the top plate of the anchor beam and marked with a marking needle and a sample punch.

[0078] In one embodiment, after obtaining the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate, the following steps are performed:

[0079] Based on the theoretical distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate, and the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate, the distance deviation between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate is calculated.

[0080] It should be understood that after measuring the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate, it is also necessary to calculate the distance deviation between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate. Specifically, the absolute value of the difference between the theoretical distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate and the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate can be calculated to calculate the distance deviation between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate.

[0081] In step S104, measuring the actual distance of the anchor point 610 in the height direction includes:

[0082] The determined anchor point 610 is extended outside the anchor box 600, and then the line is suspended toward the bottom plate of the anchor beam to measure the actual distance of the anchor point 610 in the height direction.

[0083] It should be understood that after measuring the actual distance between the anchor point 610 and the horizontal plane's transverse baseline, and the actual distance between the anchor point 610 on one side of the web and the longitudinal baseline on the top plate, it is also necessary to measure the actual distance of the anchor point 610 in the height direction. The measurement can be done specifically according to the wire hanging method. Before hanging the wire, the determined anchor point 610 needs to be extended outside the anchor box 600, and then the wire is hung from the extension point outside the anchor box 600 toward the bottom plate of the anchor beam, and the wire distance on the bottom plate is measured, so that the actual distance of the anchor point 610 in the height direction can be measured.

[0084] In one embodiment, the distance deviation of the anchor point 610 in the height direction is calculated according to the theoretical distance of the anchor point 610 in the height direction and the actual distance of the anchor point 610 in the height direction.

[0085] It should be understood that after measuring the actual distance of the anchor point 610 in the height direction, it is also necessary to calculate the distance deviation of the anchor point 610 in the height direction. Specifically, the absolute value of the difference between the theoretical distance of the anchor point 610 in the height direction and the actual distance of the anchor point 610 in the height direction can be calculated to calculate the distance deviation of the anchor point 610 in the height direction.
