Description

Technical Field

[0001] This invention relates to the field of building decoration construction technology, specifically to a quick positioning and marking device for the angle baseline of decorative blocks and its usage method, which is suitable for angle positioning and baseline marking of irregularly shaped decorative blocks such as floors and walls before cutting. Background Technology

[0002] In architectural decoration construction, decorative blocks such as stone, ceramic tiles, and terracotta panels often need to be spliced ​​and laid according to design patterns, especially in artistic flooring, irregularly shaped walls, areas to avoid openings, or irregular mosaic areas, where each decorative block often has different angles, side lengths, and outlines. During construction, it is usually necessary to mark cutting baselines on the surface of the blocks according to the design drawings, and then cut and number them according to the baselines to ensure that the splicing relationship between the blocks is consistent with the design effect. In this type of project, each stone block needs to be cut on-site at different angles according to the design drawings.

[0003] Current construction methods often employ tools such as angle gauges, rulers, and ink lines, combined with manual measurement and line drawing. Construction workers must repeatedly search for angles, measure side lengths, mark corner points, and draw cutting lines. When there are many decorative blocks, significant shape variations, or complex angular relationships, these methods involve numerous steps, resulting in low positioning efficiency. Furthermore, manual measurement is prone to errors due to angle readings, line deviations, or block movement, affecting cutting accuracy and tiling efficiency. Simultaneously, traditional tools lack a unified angle positioning benchmark and line-marking limit structure, making it difficult to continuously complete angle selection, block positioning, ink line marking, and benchmark line setting on a single device. Therefore, it is necessary to provide a device and its usage method that can quickly locate angles and mark angle benchmark lines on decorative blocks.

[0004] How to solve the above-mentioned technical problems is the challenge facing this invention. Summary of the Invention

[0005] The purpose of this invention is to provide a quick positioning and marking device for the angle baseline of decorative blocks, including a positioning frame, an angle positioning component, a center positioning component, a marking component, and a clamping and positioning component.

[0006] The positioning frame includes a straight reference edge and an arc-shaped scale edge connecting the two ends of the straight reference edge. The straight reference edge and the arc-shaped scale edge form a positioning area for the decorative block. Several angle scale lines are provided on the arc-shaped scale edge.

[0007] The angle positioning component includes a plurality of angle positioning holes spaced apart along the arc-shaped scale edge and a limiting pin that can be detachably inserted into the angle positioning holes.

[0008] The central positioning component is located at the middle of the straight reference edge.

[0009] The snap-on assembly includes an ink thread connected to the central positioning assembly and an ink cartridge sleeved on the ink thread.

[0010] The central positioning component and the clamping positioning component are spaced apart along the width direction of the straight reference edge. The central positioning component is located on the side closer to the arc-shaped scale edge, and the clamping positioning component is located on the side away from the arc-shaped scale edge.

[0011] The positioning frame is positioned above the decorative block, with the area of ​​the decorative block to be marked corresponding to the positioning area. The central positioning component forms the starting position of the ink line, and the limiting pin forms the angle limiting position of the ink line, allowing the ink line to extend from the middle of the straight reference edge towards the arc-shaped scale edge. The clamping positioning component is independently configured with respect to the central positioning component, clamping the decorative block without occupying the area where the ink line extends towards the arc-shaped scale edge.

[0012] The positioning frame is a semi-circular frame structure formed by the straight reference edge and the arc-shaped scale edge. The straight reference edge is a strip plate extending along the diameter direction of the semi-circular frame structure. The arc-shaped scale edge is the arc edge of the semi-circular frame structure. The angle scale line is arranged radially along the arc-shaped scale edge, and the angle positioning holes are respectively located on the corresponding angle scale lines.

[0013] The positioning frame can be formed by cutting sheet metal to create the straight reference edge and the arc-shaped scale edge, and then machining the angle scale lines and angle positioning holes along the arc-shaped scale edge. The extension direction of the angle scale lines is towards the center position of the straight reference edge, so that different angle positioning holes correspond to different ink line extension angles. The middle part of the semi-circular frame structure remains open so that the surface of the decorative block to be marked is exposed in the positioning area.

[0014] The center positioning component includes a center positioning hole and a center fixing pin. The center positioning hole is located at the center of the straight reference edge, and the center fixing pin is inserted into the center positioning hole. One end of the ink line is connected to the center fixing pin and extends from the center fixing pin toward the arc-shaped scale edge.

[0015] During installation, first, the center positioning hole is machined at the center position of the straight reference edge. Then, the center fixing pin is inserted into the center positioning hole, and one end of the ink line is tied to the center fixing pin. The center fixing pin is located at the center of the semi-circular frame structure, so that when the ink line is switched between different limiting pins, the center fixing pin serves as the unified starting position for the snap line.

[0016] The limiting pin includes a plug rod and a wire stop cap connected to the upper end of the plug rod. The plug rod is inserted into the angle positioning hole, and a wire clamping gap is formed between the wire stop cap and the upper surface of the positioning frame. The ink line is threaded through the wire clamping gap.

[0017] The plug rod engages with the angle positioning hole, and the limiting pin can be installed in the corresponding angle positioning hole according to the angle to be set. The ink line rope passes around the plug rod and enters the wire clamping gap, and the wire stop cap is located above the ink line rope to prevent the ink line rope from coming out along the axial direction of the plug rod during tensioning and wire setting.

[0018] The ink cartridge includes a cartridge body, an ink storage cavity, an inlet port, and an outlet port.

[0019] The ink storage cavity is disposed inside the box body, and the inlet hole and the outlet hole are respectively disposed on opposite sides of the box body. The ink thread rope passes through the inlet hole, the ink storage cavity and the outlet hole in sequence.

[0020] The ink storage chamber is equipped with a sponge, and the sponge is provided with a wire passage connecting the inlet hole and the outlet hole. The ink thread is threaded through the wire passage and in contact with the sponge.

[0021] During assembly, the sponge is placed inside the ink storage chamber, with both ends of the lead-through channel corresponding to the inlet and outlet holes, respectively. The ink thread is then inserted through the inlet hole, passes through the lead-through channel, and exits through the outlet hole. After ink is added to the sponge, the ink cartridge moves along the ink thread, causing the ink thread to contact the sponge and adhere to the ink.

[0022] The ink-lined rope has multiple length marker knots, and the spacing between two adjacent length marker knots is equal.

[0023] Along the extension direction of the ink line, the ink cartridge is located between the central positioning component and the length marker knot closest to the central positioning component.

[0024] Each of the length marker knots is sequentially arranged along the length direction of the ink line to form equidistant length references. In use, the ink line is straightened along the pre-marked baseline, and the corresponding length marker knot is selected according to the side lengths between adjacent corner points recorded in the design drawings to determine the next corner point. The ink cartridge is positioned between the central positioning component and the length marker knot closest to the central positioning component, allowing the ink line near the pre-marked area to pass through the ink cartridge.

[0025] The clamping and positioning assembly includes a base plate, a through screw, and a locking nut.

[0026] The base plate is positioned below the positioning frame, and a clamping gap for the decorative block is formed between the base plate and the positioning frame.

[0027] The through screw is located on the side of the central positioning component away from the arc-shaped scale edge, and passes vertically through the base plate and the straight reference edge in sequence.

[0028] The lower end of the through screw is provided with a screw head that abuts against the lower surface of the base plate, and the upper end of the through screw extends out of the straight reference edge and is threadedly connected to the locking nut, which is located above the straight reference edge.

[0029] The edge of the decorative block extends into the clamping gap between the base plate and the positioning frame, and the through screw is located on the outside of the decorative block and spaced apart from the decorative block.

[0030] During assembly, the through screws are passed sequentially from bottom to top through the base plate and the straight reference edge, with the screw head abutting the lower surface of the base plate. Then, the locking nut is screwed onto the upper end of the through screw. The decorative block extends into the clamping gap from the side closest to the positioning area, without being passed through by the through screw. When the locking nut is tightened, the distance between the base plate and the straight reference edge decreases to clamp the decorative block; after loosening the locking nut, the relative position between the positioning frame and the decorative block can be adjusted.

[0031] The present invention also provides a method for using the above-mentioned quick positioning chalk line device for decorative block angle reference lines, comprising the following steps: S1. Determine the corner sequence, angle of each corner, and side length between adjacent corners of the decorative blocks to be cut according to the design drawings.

[0032] In this step, each corner point is determined sequentially according to the outline direction of the decorative block, and the angle corresponding to each corner point and the side length between adjacent corner points are recorded as the basis for subsequent device positioning and line marking.

[0033] S2. Place the decorative block below the positioning frame, so that the area of ​​the decorative block to be marked corresponds to the positioning area, and align the initial edge of the decorative block with the straight reference edge; extend the edge of the decorative block from the side near the positioning area into the clamping gap between the base plate and the straight reference edge, tighten the locking nut, and clamp the decorative block between the base plate and the straight reference edge.

[0034] In this step, the through screw is located on the outside of the decorative block, the surface of the decorative block to be marked is exposed in the positioning area, and the straight reference edge corresponds to the initial edge of the decorative block.

[0035] S3. Wrap the ink line around the limiting pin corresponding to the zero-degree scale, tighten the ink line, and pop out the first baseline on the decorative block.

[0036] The first baseline extends from the central fixing pin to the limiting pin corresponding to the zero-degree scale, and serves as the initial reference line for the first corner angle.

[0037] S4. Wrap the ink line around the limiting nail corresponding to the angle of the first corner point, tighten the ink line, and pop out a second baseline on the decorative block. The first baseline and the second baseline intersect to form the first corner point.

[0038] In this step, the ink line is removed from the limiting pin corresponding to the zero-degree scale and then wound around to the limiting pin corresponding to the angle of the first corner point, so that the second baseline and the first baseline form a corresponding angle.

[0039] S5. Determine the next corner point on the popped-up baseline according to the side length between adjacent corner points. Loosen the locking nut, move the positioning frame so that the center fixing nail corresponds to the next corner point, and align the straight reference side with the baseline connecting the previous corner point and the next corner point. Retighten the locking nut, wrap the ink line around the limiting nail corresponding to the angle of the next corner point, pop up the next angle baseline, and determine the subsequent corner points and angle baselines in sequence.

[0040] After each new corner point is determined, the locking nut is loosened, the positioning frame is moved so that the central fixing pin moves to the corresponding corner point, and then the decorative block is re-clamped. By repeating the process of moving, aligning, and clamping the positioning frame, the angle reference lines at each subsequent corner point are sequentially marked.

[0041] S6. Cut the decorative blocks along the baseline at each angle, number the cut decorative blocks, and lay them in the order of the numbers.

[0042] In this step, the decorative blocks are cut according to the outline formed by the baselines at each angle, and the numbers of the cut decorative blocks are matched with the laying positions in the design drawings. Then, they are laid in the order determined by the numbers.

[0043] In steps S3 to S5, before the ink line is snapped, the ink cartridge is moved along the ink line rope, so that the ink line rope passes through the sponge in the ink storage cavity and comes into contact with the sponge to attach ink. Then the ink line rope is pulled away from the surface of the decorative block and released, so that the ink is attached to the surface of the decorative block to form an angle reference line.

[0044] When snapping the line, first move the ink cartridge so that the ink line rope located between the central fixing pin and the corresponding limiting pin is attached with ink; then pull the ink line rope tight, lift the ink line rope away from the surface of the decorative block and release it, so that the ink line rope contacts the surface of the decorative block and leaves a linear ink mark.

[0045] In step S5, the spacing between two adjacent length marker knots is equal, and the corresponding length marker knot is selected according to the side length between adjacent corner points to determine the position of the next corner point.

[0046] When determining the next corner point, straighten the ink line along the already marked baseline. Using the previous corner point as the starting position for length, select the corresponding length marker knot according to the designed side length, and mark the next corner point at that position. After marking the next corner point, move the positioning frame so that the central fixing nail corresponds to the next corner point, and then mark the next angle baseline.

[0047] The beneficial effects of this invention are as follows: By coordinating a positioning frame, angle positioning component, center positioning component, chalk line component, and clamping positioning component, the decorative block is stably positioned by the clamping positioning component and the straight reference edge before cutting. The center positioning component then serves as a unified chalk line reference point, and the chalk line direction is limited by limiting pins at different angles, thus forming a reference line at the corresponding angle on the surface of the decorative block. Compared to the traditional method of repeatedly using angle rulers, straightedges, and chalk lines for angle measurement, marking, and line drawing in construction, this invention integrates the positioning, angle selection, and chalk line setting of the decorative block on a single device, reducing repetitive on-site measurements and manual drawing steps, and improving the efficiency of laying out lines before cutting irregularly shaped decorative blocks. Because the angle positioning holes correspond to the angle scale lines, the chalk line forms the corresponding angle chalk line direction after being wound around the corresponding limiting pin, thus reducing errors caused by manual reading, manual drawing, and line offset. Simultaneously, the clamping positioning component restricts the movement of the decorative block during the chalk line process, ensuring a relatively stable positioning foundation for each angle reference line. By applying ink to the ink line using an ink cartridge, a clear cutting baseline can be directly formed on the surface of the decorative blocks, facilitating subsequent cutting operations. After cutting, the decorative blocks are numbered and laid out in sequence, which helps reduce the time spent searching, comparing, and adjusting irregularly shaped blocks on-site. Therefore, this invention can better adapt to the layout requirements of irregular decorative blocks with multiple angles and large shape variations in construction scenarios such as artistic flooring, wall tiling, and opening avoidance, corresponding to the effects of shortening the construction period and saving construction costs proposed in the document.

[0055] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0056] See Figures 1 to 6 As shown, this embodiment provides a quick positioning and marking device for the angle baseline of decorative blocks, including a positioning frame 1, an angle positioning component, a center positioning component, a marking component 4, and a clamping and positioning component 5.

[0057] The positioning frame 1 is formed by laser cutting from a 3mm thick 304 stainless steel plate. The positioning frame 1 includes a straight reference edge 11 and an arc-shaped scale edge 12 connecting the two ends of the straight reference edge 11. The straight reference edge 11 and the arc-shaped scale edge 12 form a semi-circular positioning area. The outer radius of the positioning frame 1 is 400mm, and the radial width of the arc-shaped scale edge 12 is 40mm. The straight reference edge 11 is a strip-shaped plate extending along the diameter of the positioning frame 1, with a length of 800mm and a width of 50mm. The straight reference edge 11 and the arc-shaped scale edge 12 are integrally cut, and the edges are deburred after cutting.

[0058] Several angle scale lines 13 are set on the arc-shaped scale edge 12. The angle scale lines 13 are set sequentially from 0° to 180° with the center position of the straight reference edge 11 as the angle center, and the angle interval between two adjacent angle scale lines 13 is 5°. The angle scale lines 13 are formed by laser etching, with a line width of 0.3mm and a line depth of 0.2mm, and the corresponding angle value is etched at every 10° position.

[0059] The angle positioning component includes several angle positioning holes and limiting pins 22. The angle positioning holes are respectively formed on the corresponding angle scale lines 13, and the centers of all the angle positioning holes are located on the same arc line. The distance between this arc line and the center of the straight reference edge 11 is 380mm. The angle positioning holes are circular through holes with a diameter of 1.6mm.

[0060] The limiting pin 22 is made of 304 stainless steel and includes a connector rod and a wire stop cap connected to the upper end of the connector rod. The connector rod has a diameter of 1.5 mm and a length of 10 mm, and the wire stop cap has a diameter of 4 mm and a thickness of 1.5 mm. After the connector rod is inserted into the angle positioning hole, a wire clamping gap of 1.2 mm is left between the wire stop cap and the upper surface of the positioning frame 1. The ink line 41 passes around the connector rod and is threaded through the wire clamping gap. In this embodiment, four limiting pins 22 are configured, and the limiting pins 22 are inserted into the corresponding angle positioning holes according to the angle of the chalk line.

[0061] The center positioning assembly includes a center positioning hole 31 and a center fixing pin 32. The center positioning hole 31 is located at the center of the linear reference edge 11 along its length and on the side of the linear reference edge 11 closest to the arc-shaped scale edge 12 along its width. The diameter of the center positioning hole 31 is 1.6 mm, and the distance between the center of the center positioning hole 31 and the edge of the linear reference edge 11 closest to the arc-shaped scale edge 12 is 12 mm. The center fixing pin 32 is a stainless steel round pin with a diameter of 1.5 mm and a length of 12 mm. The center fixing pin 32 is inserted into the center positioning hole 31, with its upper end protruding 6 mm above the upper surface of the linear reference edge 11.

[0062] The string assembly 4 includes an ink string 41, an ink cartridge 42, and a length marking knot 43. The ink string 41 is made of cotton ink thread with a diameter of 1 mm, and the total length of the ink string 41 is 1200 mm. One end of the ink string 41 is tied to the central fixing pin 32 and extends from the central fixing pin 32 toward the arc-shaped scale edge 12.

[0063] The ink cartridge 42 is a rectangular box, comprising a body 421, an ink reservoir 422, an inlet port 423, an outlet port 424, and a sponge 425. The body 421 is made of plastic and measures 40mm in length, 20mm in width, and 15mm in height. The ink reservoir 422 is located inside the body 421 and measures 32mm in length, 14mm in width, and 11mm in height.

[0064] The inlet hole 423 and outlet hole 424 are respectively located on opposite sides of the length of the cartridge 421. Both the inlet hole 423 and outlet hole 424 have a diameter of 2mm, and their centers are on the same straight line. A sponge 425 is filled into the ink storage chamber 422. A 1.2mm diameter thread channel is formed in the middle of the sponge 425, with its two ends corresponding to the inlet hole 423 and outlet hole 424, respectively. The ink thread 41 passes sequentially through the inlet hole 423, the thread channel in the middle of the sponge 425, and the outlet hole 424, and contacts the inner wall of the thread channel. 5mL of water-based ink is added to the sponge 425.

[0065] Multiple length marker knots 43 are set on the ink thread 41. The first length marker knot 43 is set 50mm away from the central fixing pin 32, and subsequent length marker knots 43 are set sequentially along the extension direction of the ink thread 41, with a distance of 50mm between any two adjacent length marker knots 43. Each length marker knot 43 is formed by knotting the ink thread 41 itself, and the outer diameter of the knot is 2.5mm. Along the extension direction of the ink thread 41, the ink cartridge 42 is set between the central fixing pin 32 and the first length marker knot 43. An ink cartridge limiter 44 is set at the end of the ink thread 41 away from the central fixing pin 32. The ink cartridge limiter 44 is made of rubber, is frustum-shaped, has a maximum outer diameter of 12mm, a height of 10mm, and a threading hole with a diameter of 1.2mm in the middle. The free end of the ink thread 41 is passed through the thread hole and then knotted for fixation. The ink cartridge limiter 44 is located below the ink cartridge 42, and the maximum outer diameter of the ink cartridge limiter 44 is larger than the diameter of the inlet hole 423 and the outlet hole 424. Multiple length marking knots 43, ink cartridges 42, and ink cartridge limiters 44 are arranged sequentially along the direction from the central fixing pin 32 to the free end of the ink thread 41.

[0066] The clamping and positioning assembly 5 is located at the midpoint of the straight reference edge 11 along its length, and is spaced apart from the center positioning assembly along the width of the straight reference edge 11. The center positioning assembly is located on the side closer to the arc-shaped scale edge 12, and the clamping and positioning assembly 5 is located on the side away from the arc-shaped scale edge 12. The center distance between the center fixing pin 32 and the through screw 52 is 26mm.

[0067] The clamping and positioning assembly 5 includes a base plate 51, a through screw 52, ​​and a locking nut 53. The base plate 51 is made of 304 stainless steel plate with a thickness of 3mm. The base plate 51 is rectangular, with a length of 100mm and a width of 35mm. The base plate 51 is positioned below the straight reference edge 11 and is centrally located along the length of the straight reference edge 11. A clamping gap for the decorative block is formed between the base plate 51 and the straight reference edge 11.

[0068] The through screw 52 is an M6×50mm stainless steel screw. The through screw 52 passes vertically through the base plate 51 and the straight reference edge 11, respectively. Both the base plate 51 and the straight reference edge 11 have through holes with a diameter of 6.5mm. The through screw 52 is located on the side of the central fixing pin 32 opposite to the arc-shaped scale edge 12.

[0069] The lower end of the through screw 52 has a screw head that abuts against the lower surface of the base plate 51. The upper end of the through screw 52 extends beyond the upper surface of the straight reference edge 11 and is threadedly connected to the locking nut 53. The locking nut 53 is an M6 wing nut and is located above the straight reference edge 11.

[0070] During assembly, first pass the through screw 52 through the base plate 51 from bottom to top, then pass the through screw 52 through the through hole on the straight reference edge 11, and then screw the lock nut 53 onto the upper end of the through screw 52. The edge of the decorative block extends from the side near the positioning area into the space between the base plate 51 and the straight reference edge 11. The through screw 52 is located on the outer side of the edge of the decorative block, with a 5mm gap between the through screw 52 and the edge of the decorative block. No hole is made on the decorative block for the through screw 52 to pass through.

[0071] In this embodiment, the aforementioned device is used to position and mark lines on a piece of decorative stone with a length of 1000mm, a width of 800mm, and a thickness of 15mm. The shape to be cut is a parallelogram. The parallelogram includes a first corner point A, a second corner point B, a third corner point C, and a fourth corner point D. The angle between the first corner point A and the third corner point C is 60°, and the angle between the second corner point B and the fourth corner point D is 120°. The side length from the first corner point A to the second corner point B is 600mm, the side length from the second corner point B to the third corner point C is 400mm, the side length from the third corner point C to the fourth corner point D is 600mm, and the side length from the fourth corner point D to the first corner point A is 400mm. The specific steps include: S1. Determine the order of the first corner point A, the second corner point B, the third corner point C, and the fourth corner point D according to the design drawings, record the angles of the four corner points and the side lengths between adjacent corner points, and mark the number A1 on the back of the decorative stone.

[0072] S2. Loosen the locking nut 53 and place the decorative stone under the positioning frame 1, so that the surface of the decorative stone to be marked corresponds to the positioning area. Align one of the original straight edges of the decorative stone with the straight reference edge 11, and align the position of the first corner point A with the axis of the center fixing nail 32.

[0073] Insert the edge of the decorative stone from the side closest to the positioning area between the base plate 51 and the straight reference edge 11, with an insertion length of 30mm. Adjust the base plate 51 so that its upper surface is in contact with the lower surface of the decorative stone, and the lower surface of the straight reference edge 11 is in contact with the upper surface of the decorative stone. Rotate the locking nut 53 clockwise until it abuts against the upper surface of the straight reference edge 11, thus completing the clamping of the decorative stone and the positioning frame 1.

[0074] S3. Insert a limiting pin 22 into the angle positioning hole corresponding to the 0° angle scale line 13. Wrap the ink line 41 around the connector rod and place it into the wire clamping gap between the wire stop cap and the upper surface of the positioning frame 1.

[0075] Before marking the line, add water-based ink to the sponge 425 inside the ink cartridge 42, and move the ink cartridge 42 back and forth three times along the ink line rope 41, each time moving a distance of 30mm. Tighten the ink line rope 41 between the center fixing nail 32 and the 0° limiting nail 22, then lift the ink line rope 41 15mm off the surface of the decorative stone and release it, marking the first baseline on the surface of the decorative stone. The first baseline extends from the first corner point A to the second corner point B.

[0076] S4. Remove the ink thread 41 from the 0° limiting pin 22, insert the other limiting pin 22 into the angle positioning hole corresponding to the 60° angle scale line 13, then wrap the ink thread 41 around the outside of the insertion rod of the limiting pin 22 and place it into the wire clamping gap.

[0077] Move the ink cartridge 42 back and forth three times along the ink line rope 41 to tighten the ink line rope 41 between the central fixing nail 32 and the 60° limiting nail 22. Lift the ink line rope 41 upwards 15mm away from the surface of the decorative stone and then release it, popping out a second reference line on the surface of the decorative stone. The first reference line and the second reference line intersect at the first corner point A.

[0078] S5. Starting from the first corner point A along the first baseline, straighten the ink line rope 41. Count the lengths of the adjacent length marker knots 43 at 50mm intervals. Select the position corresponding to the twelfth length interval and mark the second corner point B at that position. The distance between the first corner point A and the second corner point B is 600mm.

[0079] Loosen the locking nut 53, move the positioning frame 1 along the first reference line, so that the axis of the center fixing nail 32 coincides with the second corner point B, and align the straight reference edge 11 with the first reference line between the second corner point B and the first corner point A. Place the edge of the decorative stone back between the base plate 51 and the straight reference edge 11, and tighten the locking nut 53 again.
