[0002] During the installation of steel structures, misalignment is a key control item, and its deviation has a significant impact on the installation. Misalignment deviation should be controlled within the permitted range of the specification. There are two main existing methods for measuring misalignment: qualitative measurement using a steel ruler, which can only determine whether misalignment exists; and quantitative measurement using a feeler gauge and a steel ruler. This method requires two measuring tools, is cumbersome to operate, has large measurement errors, requires two people to complete, and has low measurement efficiency. Utility Model Content

At this time, the value when the scale line 1 on the measuring ruler coincides with the scale on the scale line 2 on the cross bar is the misalignment value. This measurement method can measure the misalignment of the joints during the installation of the steel structure more intuitively, accurately and efficiently.

[0010] The utility model is further configured as follows: a spring 1 is installed between the two card joints, a baffle is installed at one end of the button through a locking piece, and a spring 2 is installed between the baffle and the inner bottom surface of the chamber.

[0011] The advantage of this solution is at least that the arrangement of the first spring, the second spring and the baffle plate can automatically snap the two clamping joints into the clamping grooves, making the operation more convenient.

[0013] The advantage of this solution is at least that the button cover makes it convenient for the user to press the button, and one surface of the button cover is arranged in an arc shape, making it more convenient to move the measuring ruler.

[0014] The utility model is further configured as follows: a plurality of protruding blocks are installed on the arc-shaped surface of the button cover.

[0015] The advantage of this solution is at least that the provision of the raised block can increase the friction between the finger and the button cover, thereby preventing the hand from slipping during use.

[0016] The utility model is further configured as follows: the cross bar, the fixing block and the measuring ruler are made of high-strength stainless steel.

[0017] The advantages of this solution are at least that the high-strength stainless steel material has excellent wear resistance and corrosion resistance, which increases the service life of the measuring tool.

[0018] In summary, the present invention has at least the following advantages:

DETAILED DESCRIPTION

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] A tool for measuring the misalignment of steel structure installations, such as Figure 1 、 Figure 2 As shown, the crossbar 1 includes a fixed block 2 mounted at one end for contact with the mating surface. The fixed block 2 is integrally formed with the crossbar 1. A sliding slot 3 is defined at the end away from the fixed block 2, within which a measuring ruler 4 is slidably mounted. The crossbar 1, fixed block 2, and measuring ruler 4 are made of high-strength stainless steel. This measuring tool is suitable for, but not limited to, measuring the alignment of steel structures. It can also measure misalignment in welded joint assembly dimensions, misalignment in steel plate shear walls, and other misalignments.

[0030] like Figure 2 、 Figure 3 As shown, a scale line 1 5 is provided on the measuring ruler 4, and a scale line 2 6 is provided on the crossbar 1. It is worth mentioning that the unit of the scale line 2 6 is mm. The scale line 2 6 on the crossbar 1 matches the clamping groove 701. A fixing assembly 7 for fixing the measuring ruler 4 is installed on the measuring ruler 4. The fixing assembly 7 includes a wavy clamping groove 701 provided on the side wall of the sliding groove 3, two clamping joints 702 located in the measuring ruler 4, and a button 703 for pushing the clamping joint 702 to move. The clamping joint 702 matches the clamping groove 701.

[0031] A chamber 8 is provided in the measuring ruler 4, and a plurality of circular holes 9 are provided on the inner side wall of the chamber 8. The circular holes 9 pass through the two side walls of the measuring ruler 4. The clamping joint 702 is slidably installed in the chamber 8 and the circular hole 9. A circular hole 2 10 is provided on the inner top surface of the chamber 8. The button 703 is slidably installed in the circular hole 2 10, and one end of the button 703 extends into the chamber 8. Two connecting rods 704 are rotatably installed on the button 703, and the end of the connecting rod 704 away from the button 703 is rotatably installed on the clamping joint 702.

[0032] like Figure 4 、 Figure 5As shown, in order to increase the stability of the measuring ruler 4 moving in the sliding groove 3, in some embodiments, a sliding hole 11 is opened on the surface of the cross bar 1, and the sliding hole 11 is connected to the sliding groove 3. A sliding rod 12 is installed on the measuring ruler 4, and the scale line 1 5 is located on the sliding rod 12, and the scale line 2 6 is located next to the sliding hole 11.
