Example 3

[0036] like Figure 8 As shown, this embodiment provides a measurement method for the steel frame box column corbel assembly measurement tool described in Embodiment 1 and Embodiment 2, which specifically includes the following steps: Step 1: After the box column 22 is manufactured, the corbel 23 is assembled. When assembling, first measure the center axis of the box column on the column surface of the box column 22.

[0037] Step 2: Place the measuring tool on the cylindrical surface, make the large ruler 1 perpendicular to the length centerline of the box-type column 22, align the 0 scale value on the L-shaped slider 11 in the leveling assembly 4 with the center axis of the box-type column, or use the "0" display of the digital display screen 21 on the L-shaped slider 11 to coincide with the center axis of the box-type column; preliminarily adjust the two sliding bases 3 according to the cylindrical width of the box-type column 22, so that the two sliding bases 3 are respectively located on the cylindrical surfaces on both sides of the center axis of the box-type column, and the bottom end of the leveling bolt 10 on the sliding base 3 is stably supported on the cylindrical surface.

[0038] Step 3: Rotate the infrared line measuring instrument 14 so that the infrared rays emitted by it coincide with the center axis of the box column, and adjust the leveling bolts 10 on the sliding base 3, and observe the bubble of the level 15 to make the large scale 1 in a horizontal state.

[0039] Step 4: Slide the two sliding bases 3 so that the clamping columns 7 on the two sliding bases 3 are respectively clamped on both sides of the box-type column 22, and the abutting protrusions 8 abut against the sides of the box-type column 22. Then tighten the fastening bolts 6 on the two sliding bases 3, and read the size of the box-type column center axis from the two side surfaces through the position of the two sliding bases 3, or read, display and record the size of the box-type column center axis from the two side surfaces through the digital display screens 21 on the two sliding bases 3.

[0040] Step 5: The cursor pointer 20 assembly 5 slides on the large scale 1 through the cross slider 19 to the vicinity of the assembly reference line of the corbel 23 to be measured.

[0041] Step 6: The small scale 18 slides in the cross slide block 19 to drive the slide bar 16 and the pointer 20 to move close to the assembly reference line of the corbel 23.

[0042] Step 7: Fine-tune the cursor pointer assembly 5 on the large scale 1 through the cross slider 19, and adjust the position of the slide bar 16 so that the pointer 20 is on the assembly reference line of the corbel 23, and tighten the corresponding fastening bolts 6; read the distance between the center axis of the box column and the assembly reference line through the position of the cross slider 19, or read, display and record the distance between the center axis of the box column and the assembly reference line of the corbel 23 through the digital display screen 21 at the bottom of the cross slider 19; Step 8: By sliding the small ruler 18 relative to the cross slider 19, measure two or more horizontal distances between the center axis of the box column and the assembly reference line of the corbel 23, measure the parallelism of the assembly reference line of the corbel 23 relative to the cylindrical surface of the box column 22, and measure the distance between the bolt holes perpendicular to the length axis direction of the corbel 23. The above measurement data can also be read, displayed and recorded through the digital display screen 21 on the upper part of the cross slider 19, and finally measure the assembly accuracy of the corbel 23 and the accuracy of the hole spacing of the mounting holes.

[0043] Furthermore, it should be noted that when there are multiple components in the centerline area of ​​the box-type column, the centerline of the box-type column cannot pop out a through line due to the obstruction of the components. At this time, the parallel borrowing line method is used to pop out a through line parallel to the centerline of the box-type column, and the leveling measurement component 4 is moved until the infrared light emitted by the infrared line measuring instrument 14 coincides with the through line. At this time, the digital display screen 21 on the leveling measurement component 4 changes from "0" to data of relative displacement with the large scale 1. Taking this through line of the cylindrical surface as the baseline of the column, the distance from the baseline to the assembly baseline of the corbel 23 is measured, thereby obtaining the distance from the centerline of the box-type column to the assembly baseline of the corbel 23.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
