For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1-4 As shown, one specific embodiment of a fixed ruler with adjustable spacing of the utility model includes two fixed parts 1 that can be connected to a steel frame. More specifically, one side of the fixed part 1 includes a magnetic strip 101, and the other side includes a lever 102. The magnetic strip 101 and the lever 102 are fixedly connected, and the lever 102 and the magnetic strip 101 are connected as a whole. The two fixed parts 1 are respectively connected to the horizontal ruler 2. Specifically, one side of the lever 102 is vertically connected to the horizontal ruler 2, and the other side is fixedly connected to the magnetic strip 101. The two fixed parts 1 are arranged opposite to each other, and the two magnetic strips 101 are respectively located on the outside of the two opposite fixed parts 1, that is, there are two horizontal rulers 2 between the two fixed parts 1. Scales 3 are set on both horizontal rulers 2, and the free ends of the two horizontal rulers 2 are connected by a telescopic joint 4, so that the two horizontal rulers 2 can overlap, lengthening or shortening the total length of the two horizontal rulers 2.

[0026] Specifically, the structure of the expansion joint 4 is that the interior of the expansion joint 4 includes a through cavity 401 for accommodating two horizontal scales 2 to pass through together, and a positioning device 5 is installed at the rear of the expansion joint 4. The positioning device 5 includes a movable arm 501 hinged at the rear of the expansion joint 4 and a magnetic block 502 arranged at the end of the movable arm 501. The two horizontal scales 2 are made of steel. There are two movable arms 501, and the magnetic blocks 502 of the two movable arms 501 can be magnetically attracted to the two horizontal scales 2 respectively. When in use, the two movable arms 501 are flipped over to make the two magnetic blocks 502 leave the two horizontal scales 2, and then the length of the horizontal scales 2 extending into the through cavity 401 is adjusted so that the total length of the two horizontal scales 2 reaches a predetermined length, and then the two movable arms 501 are flipped over to make the two magnetic blocks 502 respectively attracted to the two horizontal scales 2 for fixing.

[0027] In order to make the movable arm 501 still able to adsorb the magnet 502 on the horizontal scale 2 when the movable arm 501 is not parallel to the horizontal scale 2 and an angle is formed, a movable groove 503 is provided at the end of the movable arm 501, and the magnet 502 is installed in the movable groove 503 through a rotating shaft. The magnet 502 protrudes outside the movable groove 503, so that the angle of the magnet 502 on the movable arm 501 can be changed. In this specific embodiment, the cross-sections of the movable groove 503 and the magnet 502 are both circular, and the cross-sectional diameter of the movable groove 503 is 1.2-1.5 times the cross-sectional diameter of the magnet 502, so that the angle of the magnet 502 in the movable groove 503 can be changed.

[0028] The side of the magnetic strip 101 away from the horizontal ruler 2 is a plane and is perpendicular to the horizontal ruler 2. When in use, the magnetic strip 101 of one of the fixing parts 1 is adsorbed on the installed steel frame to maintain verticality and fixation. The scale 3 reaches the plane of the side of the magnetic strip 101 away from the horizontal ruler 2, so that the horizontal ruler 2 can read the distance to the steel frame.

[0029] During the construction process, first determine the first reference steel frame according to the drawing, and then adjust the length of the fixed ruler with adjustable spacing according to the layout requirements of the drawing frame, and adsorb the two fixed rulers with adjustable spacing on both ends of the installed reference steel frame, and install the second steel frame, and so on. It can bring convenience to construction personnel, especially the installation of ceiling frames and wall frames at high altitudes, which are closely combined and arranged with the reference steel frame as the starting point. It can solve the measurement error of installing steel frames, reduce the measurement of line laying, and improve the quality and efficiency of frame installation.

[0030] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
