Description

Technical Field

[0001] This utility model belongs to the field of architectural engineering surveying and setting out, and specifically relates to a line marking device for the edge line of an arc beam in a building. Background Technology

[0002] With the gradual development of urban construction, architectural designs are becoming increasingly diverse and personalized. Designs featuring various curved lines and surfaces to express unique architectural forms are particularly prominent, especially in public buildings such as stadiums, train stations, and airports, which boast diverse and aesthetically pleasing shapes. However, while these designs are aesthetically pleasing, they also present challenges for construction companies, especially in surveying and positioning. For axial positioning of arcs with radii of tens or even hundreds of meters, RTK, total stations, and even intelligent surveying robots are often required to complete the surveying and positioning tasks. Even so, the surveying and setting out of wall beam formwork edges and control lines on construction sites still involves a significant workload, and is characterized by slow speed and a high risk of errors. Utility Model Content

[0003] The purpose of this invention is to provide a line marking device for the edge of curved beams in buildings, so as to solve the problems of slow speed and easy error in the measurement and marking of edge lines and control lines of complex wall beam formwork.

[0004] The technical solution of this utility model is: a line marking device for the edge of an arc beam in a building, including a counterweight base, rollers and a push rod on the counterweight base, a guide wheel frame at the front end of the counterweight base, a guide wheel on the guide wheel frame, through slots on both sides of the guide wheel frame, a ruler plate slidably arranged through the through slots, a mounting seat on one side of the guide wheel frame, a locking device for fixing the ruler plate on the mounting seat, an ink cartridge holder at one end of the ruler plate, a line marking wheel installed at the bottom of the ink cartridge holder, an ink cartridge on the ink cartridge holder, an ink-absorbing material placed inside the ink cartridge, an opening at the bottom of the ink cartridge, and the line marking wheel passing through the opening to contact the ink-absorbing material.

[0005] As a further improvement of this utility model, the locking device includes a threaded rod and a locking nut. The threaded rod is mounted on the mounting base, and an adjustment groove that runs vertically through the scale plate is provided along its length. The threaded rod passes through the adjustment groove and is connected to the locking nut.

[0006] As a further improvement of this utility model, a wheel groove is provided at the bottom of the ink cartridge holder, and the guide wheel passes through the wheel groove and the opening in sequence to contact the ink-absorbing material.

[0007] The beneficial effects of this utility model are as follows: This utility model adopts a variable-distance design. By adjusting the relative position between the ruler plate and the guide wheel frame, the ink cartridge and the required offset dimension can be adjusted, thereby quickly drawing wall beam edge lines and control lines on the floor surface. The speed is superior to manual line marking, and the drawn ink lines are clear and complete, meeting construction requirements. This utility model applies the principle of parallel lines. By manually pushing the guide wheel to keep it aligned with the existing axis, straight lines and arcs parallel to the axis can be easily drawn, which is simple and efficient.

Detailed Implementation

[0014] The present invention will now be described in detail with reference to the accompanying drawings.

[0015] like Figure 1-5 As shown, a line marking device for the edge of an arc beam in a building includes a counterweight base 1, on which rollers 2 and a push rod 10 are provided. A guide wheel frame 3 is provided at the front end of the counterweight base 1, and a guide wheel 4 is provided on the guide wheel frame 3. Through slots 301 are correspondingly opened on both sides of the guide wheel frame 3. A ruler plate 8 is slidably arranged through the through slots 301. A mounting seat 302 is provided on one side of the guide wheel frame 3. A locking device for fixing the ruler plate 8 is provided on the mounting seat 302. An ink cartridge bracket 6 is provided at one end of the ruler plate 8. A line marking wheel 7 is installed at the bottom of the ink cartridge bracket 6. An ink cartridge 5 is provided on the ink cartridge bracket 6. An ink-absorbing material is placed inside the ink cartridge 5. An opening 501 is provided at the bottom of the ink cartridge 5. The line marking wheel 7 passes through the opening 501 and contacts the ink-absorbing material.

[0016] The locking device includes a threaded rod 9 and a locking nut 901. The threaded rod 9 is mounted on the mounting base 302. The scale plate 8 has an adjustment groove 801 that runs vertically along its length. The threaded rod 9 passes through the adjustment groove 801 and is connected to the locking nut 901.

[0017] The bottom of the ink cartridge holder 6 has a wheel groove 601, and the guide wheel 4 passes through the wheel groove 601 and the opening 501 in sequence to contact the ink-absorbing material.

[0018] The counterweight base 1 and the guide wheel frame 3 are processed separately and then welded together.

[0019] The ink cartridge holder 6 and the ruler plate 8 are integrated into one unit. The adjustable range of the ruler plate 8 is 50mm~350mm, which can meet the requirements of most wall beam widths. The ruler plate 8 has graduations.

[0020] The ink-absorbing material is a sponge or cotton thread. Place the sponge or cotton thread in the ink cartridge 5, pour in ink, and the line-drawing wheel 7 will pick up the ink as it rotates, allowing for continuous line drawing.

[0021] Loosen the locking nut 901, and the ruler plate 8 can move within the through groove 301. Adjust the distance between the scribing wheel 7 and the guide wheel 4 according to the drawing, and tighten the locking nut 901 to fix the ruler plate 8. Press the guide wheel 4 onto the existing axis, push the push rod 10 to keep the guide wheel 4 moving forward at a constant speed along the axis, and the scribing wheel 7 can draw the required template edge lines and control lines.
