[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0016] This embodiment discloses a tool for laying out arc structures, such as arc-shaped masonry walls. Figure 1 and Figure 2 As shown, the line-laying tool mainly consists of a plurality of positioning piers 1, two line-laying steel bars 2 and a line-laying slider 3 movably installed on the line-laying steel bars 2 and capable of sliding along the line-laying steel bars 2.
[0017] Among them, the structure of the positioning pier 1 is as follows Figure 4As shown, the positioning pier 1 includes a cylindrical body 11, and the upper and lower parts of the cylindrical body are respectively provided with through-holes 15 perpendicular to the axis of the cylindrical body 11, and the axes of the upper and lower holes 15 are parallel. The upper and lower holes 15 of the cylindrical body 11 extend horizontally outward to form a cylindrical fixing sleeve 13, which is connected to the cylindrical body 11 as a whole. The interior of the fixing sleeve 13 is hollow, and the interior of the fixing sleeve 13 and the hole 15 are mutually connected. A threaded hole 16 is provided on the fixing sleeve 13 perpendicular to the axis of the fixing sleeve 13, and the threaded hole 16 is used to install the bolt 14. The lower part of the cylindrical body 11 is provided with a support foot 12. In this embodiment, three support feet 12 are provided, and the angle between adjacent support feet 12 is 120°. In this embodiment, the cylindrical body 11 is designed as a hollow structure, which is lightweight and easy to carry. To increase the stability of the positioning pier 1, the support legs 12 are designed as solid structures in the shape of triangular prisms. To facilitate the storage of the support legs 12, a storage slot 17 is provided on the lower side wall of the cylindrical body 11. One end of the support leg 12 is hinged to the cylindrical body 11. When it is needed, the support leg 12 can be rotated upward along the hinge point to be stored in the storage slot 17.
[0018] The structure of the pay-off slider 3 is as follows Figures 5 to 8As shown, it mainly includes a body 38, an ink cartridge 33 and a line-paying roller 34. The body 38 is cylindrical in shape as a whole. A part of the middle section of the body 38 is cut off by a cutting process to form a notch 39 with an open end. The top and bottom surfaces of the notch 39 are respectively formed with an arc-shaped steel bar groove 31. A handle 32 is provided on the top of the body 38. The handle 32 is divided into a cylindrical rod and a stacked circular ring structure. The bottom end of the cylindrical rod is fixed to the top of the body 38. The circular ring structure is convenient to hold and not easy to slip. A through axle hole 36 is provided on the body 38 below the lower steel bar groove 31. The axis of the axle hole 36 is perpendicular to the axis direction of the steel bar groove. An embedding groove 37 is provided at the bottom of the body 38. The embedding groove 37 extends to the side walls of the body 38 on both sides of the axle hole 36. The line-paying roller 34 is embedded in the embedding groove 37 and is installed in the axle hole 36 with an axle 35. An ink cartridge 33 is mounted on the body 38 below the lower rebar slot 31. The cartridge 33 consists of an upper ink reservoir 331 and a lower sponge pad 332. The ink reservoir 331 stores ink for line payout, while the sponge pad 332 absorbs the ink and deposits it onto the payout roller 34. A drip hole is defined at the bottom of the ink reservoir 331, and the sponge pad 332 is fixedly mounted thereto. Ink dripping from the reservoir 331 is absorbed by the sponge pad 332. In this embodiment, the sponge pad 332 has a triangular structure, with one corner facing downward, forming an inverted triangle. A groove 333 is formed on the side of the sponge pad 332 near the payout roller 34. A portion of the payout roller 34 fits into the groove 333, contacting the sponge pad 332. Because the payout roller 34 has a relatively rough surface, contact with the sponge pad 332 can contaminate the ink. As the payout roller 34 rolls, it can draw a line on the ground.
[0019] The wire reinforcement 2 has a certain flexibility. The wire reinforcement 2 is passed through the insertion holes 15 on the positioning pier 1 in sequence, so that a certain curvature can be formed between adjacent positioning piers 1. In order to prevent the wire reinforcement 2 from escaping from the insertion holes 15 of the positioning pier 1, through holes are opened at both ends of the wire reinforcement 2 perpendicular to the axis direction of the wire reinforcement 2. When the wire reinforcement 2 passes through the positioning pier 1 at the end (such as Figure 3 As shown), a cross-shaped end clamp 4 is inserted into the through hole of the laying-out steel bar 2.
[0020] When using the above-mentioned laying-out tool to lay out the construction of the arc structure, the laying-out method is as follows: Step 1): First confirm the location of the arc structure to be constructed on the drawing, and then select multiple positioning points on the arc line where the arc structure is located. The positioning points must include the two endpoints of the arc line and the points between the two endpoints. If the arc line is short, only the two endpoints and the midpoint can be taken; if the arc line is long, in addition to the two endpoints, several more points can be taken between the two endpoints. Finally, according to the coordinate system of the drawing, measure the coordinates of each selected positioning point.
[0021] Step 2): Establish a coordinate system at the construction site, and then determine and mark the position of each positioning point by measuring at the construction site based on the coordinates of each positioning point measured in step 1).
[0022] Step 3): After completing step 2), place a positioning pier 1 at each positioning point on the construction site, and adjust the orientation of each positioning pier 1 so that the line connecting the center of the arc structure on the construction site to the center point of each positioning pier 1 is perpendicular to the axis of the socket 15 of the positioning pier 1.
[0023] Step 4): After placing the positioning pier 1, pass the two wire-laying steel bars 2 through the sockets 15 on each positioning pier 1 in turn, and finally install end clamps 4 at both ends of the wire-laying steel bars 2 to limit the wire-laying steel bars 2 to prevent the wire-laying steel bars 2 from falling off the positioning pier 1.
[0024] Step 5): After installing the laying-out steel bars 2, insert the bolts 14 into the threaded holes 16 of each positioning pier 1, and tighten the bolts 14 to fix the laying-out steel bars 2 to prevent the laying-out steel bars 2 from moving relative to the positioning pier 1.
[0025] Step 6): First, apply lubricant to the exposed part of the laying-out steel bar 2, and then install the laying-out slider 3 on the laying-out steel bar 2 between one group of adjacent positioning piers 1. When installing the laying-out slider 3, make the two laying-out steel bars 2 each be stuck into the corresponding steel bar slot 31. Hold the handle 32 and slide the laying-out slider 3 from one end of the laying-out steel bar 2 to the other end. The laying-out roller 34 stained with ink rolls along the construction ground and then draws the corresponding arc. The laying-out slider 3 is movably installed on the laying-out steel bar 2 for easy installation and removal. After the laying-out slider 3 completes the marking between one group of adjacent positioning piers 1, the laying-out slider 3 is first removed and then installed on the laying-out steel bar 2 between the next group of adjacent positioning piers 1 to continue to complete the next section of marking, and so on until all the markings are completed.
[0026] Step 7): After all the marking is completed, loosen the bolts 14, pull out the line-laying steel bars 2 from the positioning pier 1, move the positioning pier 1 away from the construction site, and after removing the line-laying tools, you can start the construction of the arc structure.
