Embodiment Construction
[0022] A positioning and marking instrument for structural components of the present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.
[0023] Scribe a cylindrical member with a radius of 50cm and a height of 50cm. The requirement for scribing is: draw arc segments with an interval of 5cm on the surface of the cylinder at 15cm above and below the center of the cylinder.
[0024] as attached Figure 1-4 As shown, the structure of a positioning and marking instrument for structural members is to engrave scales on six rectangular section bars 102, and weld one end of them together, and form the rectangular section bar 102 sets from the other end of the rectangular section bar 102 Upper positioning splint 101, welding a cylindrical connector 104 at the center of six rectangular section rods 102 welding, welding dial 201 above the cylindrical connector 104, and installing rotating shaft 202 at the center of dial...

Abstract
The invention discloses a positioning scribing instrument for a structural member and a using method thereof. The positioning scribing instrument is composed of an instrument fixing device and a positioning scribing device. The instrument fixing device is formed by welding rectangular-section rod pieces to the bottom end of a cylindrical connector, and a positioning clamping plate is fixed to eachrectangular-section rod piece through a one-way locking screw. The positioning scribing device is formed by welding a protractor to the side face of a rotating shaft in the center of a dial at the top end of the cylindrical connector, an n-shaped steel frame is welded to the upper surface of the rotating shaft, the n-shaped steel frame is connected with a positioning sleeve through a two-way locking screw on the positioning sleeve, a U-shaped groove is welded to the bottom end of the positioning sleeve, and an ink sprayer is fixed in the U-shaped groove through a two-way locking screw. The positioning scribing instrument is reasonable and reliable in structural design, the scribing position can be adjusted according to different sizes, different shapes and different requirements, and thepurpose of accurate positioning scribing on the surface of the structural member in engineering practice and scientific research is effectively achieved.
Description
technical field [0001] The invention relates to the fields of civil engineering and engineering mechanics, in particular to a positioning and marking instrument for structural components and a use method thereof. Background technique [0002] In engineering practice and scientific research work, in order to drill holes or install equipment on structural components, precise positioning on the surface of structural components is required. The basic method of positioning is to use a tape measure and a pencil to measure the scale on the surface of structural components and surround them. Structural members and draw lines along the axial direction of structural members to find out the precise position. But this method is time-consuming and labor-intensive, and because the tape measure is soft and cannot draw a precise straight line around the structural member, there is a large error in positioning. [0003] Before the present invention, the invention with the application number...
