[0001] The invention relates to the technical field of building construction measurement, in particular to a device for drawing irregular curves and a line-laying method thereof. Background Art

[0002] With the development of the construction field, people are not limited to the functional requirements of buildings, but have a further pursuit of the appearance of buildings. They have established connections between such requirements and architectural shapes, and many special shapes have emerged. Curves, arcs, and three-dimensional surfaces are important components of these shapes. However, in the existing construction technology system, the construction of arc-shaped and curved reinforced concrete structures mostly uses traditional steel bars, formwork, and concrete construction processes. In this process, formwork assembly and layout is the core link to control the quality of building construction, and its layout accuracy is directly related to the fit and refinement level of the actual built building shape and the shape planned in the design drawings.

[0003] However, in traditional construction, since the templates are mostly flat plate materials, it is difficult to prefabricate in the factory when dealing with non-standard curved structures. If conventional construction layout methods are used, it is difficult to accurately control the layout accuracy. This is because the layout of non-standard curved structures requires precise calculation and positioning, and when working with other professions in construction, such as electrical and pipeline installation, due to insufficient layout accuracy, position collisions are very likely to occur, resulting in subsequent construction progress being hindered. Therefore, a device that can effectively solve the problem of irregular curve layout is developed to meet the needs of irregular curve layout construction in construction.

[0010] Furthermore, the non-rigid hose is provided with a first movable groove and a second movable groove, the ruler is placed in the non-rigid hose through the first movable groove, and the ruler is vertically connected with a peg passing through the second movable groove.

[0011] Furthermore, magnetic elements are provided at both ends of the square tube.

[0012] Furthermore, a rotating wheel is provided at the end of the screw rod away from the ruler.

[0013] Furthermore, the ruler is marked with scale lines, and the scale lines are displayed inside and outside the square tube.

[0014] Furthermore, both ends of the non-rigid hose are provided with sealing caps.

[0015] In a second aspect, a method for drawing an irregular curve includes: Obtain the curve to be laid out, perform grid positioning on the curve to be laid out and form n calibration points, wherein the spacing of the n calibration points projected on the horizontal line is consistent with the spacing of the multiple rulers; Taking the first calibration point as the reference point, obtain the position coordinates of the remaining reference points in the y-axis direction of the lofting curve; The device for drawing irregular curves is placed above the template to be processed, and the scale displayed by the first ruler at the contact point of the square tube is used as the first calibration point.

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] Example 1 Reference Figure 1 A device for drawing an irregular curve in this embodiment includes a plurality of rulers 1 distributed in an array, the rulers 1 are formed with a line-forming end 101 and a positioning end 102, the line-forming ends 101 of the plurality of rulers 1 are connected with a non-rigid hose 2, the line-forming ends 101 of the plurality of rulers 1 are movably arranged in the non-rigid hose 2, the positioning ends 102 of the plurality of rulers 1 are connected with a positioning assembly 3 for fixing the ruler 1, the positioning assembly 3 fixes the plurality of rulers 1 at different positions along the axis of the ruler 1, and the line-forming ends 101 are connected to form an irregular curve, so that the non-rigid hose 2 presents an irregular curve shape.

[0022] A plurality of rulers 1 are arranged in an array, and their line ends 101 are connected to the non-rigid hose 2 and can move inside the non-rigid hose 2. By adjusting the position of the positioning end 102 of the ruler 1 by the positioning assembly 3, the relative position of the line end 101 of the ruler 1 inside the non-rigid hose 2 can be controlled. Since the line end 101 of the ruler 1 acts together on the non-rigid hose 2, as the position of the ruler 1 changes, the non-rigid hose 2 will be correspondingly shaped into a shape similar to the designed curve. This method can adapt to a variety of complex curve shapes, whether it is a smooth wavy curve in the architectural exterior design, or a special curve with local depressions or protrusions, it can be achieved by adjusting the extension length of the ruler 1.

[0023] The non-rigid hose 2 can be bent under the application of external force and can maintain the shape formed by the external force. It can automatically recover when the external force is lost, or it can be manually restored to its original state. A PPR plastic pipe, a hose woven with metal wire, or a hose made of rubber can be used.

[0024] Reference Figure 1 and Figure 2 The positioning assembly 3 includes a long square tube 301 and a locking unit. The square tube 301 has two opposite surfaces formed with a plurality of through holes spaced apart and arranged oppositely. The ruler 1 passes through the oppositely arranged through holes. The ruler 1 can move in the through holes along the axial direction of the ruler 1. The locking unit limits the positioning end 102 of the ruler 1 to the side of the square tube 301 away from the line end 101.

[0025] A plastic protective sleeve is arranged at the through hole.

[0026] Reference Figure 1 The locking unit includes a door-shaped block 304 and a screw rod 302. The door-shaped block 304 includes a cross arm 306 and two side walls 305. The door-shaped block 304 is connected to the side wall 305 on the side of the square tube 301 away from the line-forming end 101. A cylindrical threaded cap 307 is connected to the cross arm 306 of the door-shaped block 304. The axis of the threaded cap 307 is colinear with the axis of the ruler 1. The screw rod 302 is screwed into the threaded cap 307 and passes through the cross arm 306 to be transmission-connected with the ruler 1. The screw rod 302 drives the ruler 1 to make the ruler 1 move in the through hole of the square tube 301.

[0027] Reference Figure 3 The positioning end 102 of the ruler 1 is connected to a rotating fastener 4, and the rotating fastener 4 is formed with a groove 401. The end of the screw rod 302 close to the ruler 1 is formed with a protrusion 402, and the protrusion 402 is always placed in the groove 401 and can rotate in the groove 401.

[0028] Reference Figure 4The non-rigid hose 2 is provided with a first movable groove 201 and a second movable groove 202 , the ruler 1 is placed in the non-rigid hose 2 through the first movable groove 201 , and the ruler 1 is vertically connected with a peg 203 passing through the second movable groove 202 .

[0029] Magnetic elements are provided at both ends of the square tube 301 .

[0030] The end of the screw rod 302 away from the ruler 1 is provided with a rotating wheel 303 .

[0031] The ruler 1 is marked with scale lines 103 , and the scale lines 103 are displayed inside and outside the square tube 301 .

[0032] Both ends of the non-rigid hose 2 are provided with blocking caps 204 .

[0033] The ruler 1 is inserted into the non-rigid hose 2 through the first movable groove 201, and the peg 203 vertically connected to the ruler 1 passes through the second movable groove 202. This connection method not only ensures that the ruler 1 has a certain degree of freedom of movement in the non-rigid hose 2, and can change the relative position in the hose according to the adjustment of the positioning component 3, but also enables the ruler 1 and the non-rigid hose 2 to form a relatively stable connection structure. The diameter of the peg 203 is slightly smaller than the width of the second movable groove 202 to ensure smooth passage. The first movable groove 201 enables the ruler 1 to slide smoothly in the groove, and when the non-rigid hose 2 is bent and deformed, the ruler 1 can adjust its position following its shape change without causing jamming or separation.

[0034] The design of the rotating wheel 303 at the end of the screw 302 further improves the convenience of operation. The protrusion 402 rotates in the groove 401. When the screw 302 moves forward, it abuts against the groove 401, so that the ruler 1 moves forward. When the screw 302 moves backward, the protrusion 402 is still stuck in the groove 401, driving the rotating fastener 4 to move backward so that the ruler 1 moves backward. Construction personnel can accurately control the extension length of the ruler 1 according to the scale line 103 marked on the ruler 1.

[0035] The connection between the gate block 304 and the square tube 301 is welded to ensure a firm and reliable connection. The connection between the cylindrical threaded cap 307 and the cross arm 306 of the gate block 304 is achieved by thread processing, and the connection between the rotating fastener 4 and the positioning end 102 of the ruler 1 is riveted or welded to ensure that it will not loosen or disengage during the pushing process of the screw 302. The shape and size matching accuracy of the groove 401 of the rotating fastener 4 and the protrusion 402 at the end of the screw 302 is high, the inner wall of the groove 401 is smooth, and the protrusion 402 is cylindrical and the surface is polished to reduce the friction resistance between the two, making the rotational movement smoother, thereby achieving accurate force transmission and ruler 1 position adjustment.

[0036] The blocking caps 204 at both ends of the non-rigid hose 2 play a good protective role, and at the same time limit the pin 203 and the ruler 1 in the non-rigid hose 2 to prevent them from falling out. The plastic protective cover at the through hole not only reduces the friction between the ruler 1 and the square tube 301, reducing wear, but also plays a buffering and protective role during the frequent axial movement of the ruler 1, avoiding scale wear.

[0037] A transparent observation window may be provided on the square tube 301 at a position corresponding to the scale line 103, and a red line indicating the middle position may be marked on the window. The scale includes negative numbers, 0 and positive numbers, so as to facilitate adjustment of the relative position.

[0038] Example 2 Reference Figure 5 and Figure 6 , a device for drawing irregular curves in this embodiment, the locking unit includes a square block 308 and a tie strap 309, the surface of the tie strap 309 is formed with belt teeth 310, one end of the tie strap 309 is connected to the positioning end 102 of the ruler 1, and a guide hole for the ruler 1 and the tie strap 309 to penetrate is formed on the square block 308, one end of the square block 308 is fixedly connected to the side wall 305 of the square tube 301 away from the line end 101, and the other end of the square block 308 is provided with a spring piece 311, and the spring piece 311 limits and fixes the tie strap 309, so that the ruler 1 is limited and locked.

[0039] When the position of the ruler 1 needs to be adjusted to shape an irregular curve, the construction personnel can first pull the tie strap 309 to allow the ruler 1 to move freely in the through hole of the square tube 301. Since one end of the tie strap 309 is connected to the positioning end 102 of the ruler 1, the operation is convenient and direct. When the ruler 1 moves to the target position, the shrapnel 311 at the other end of the square block 308 is used to limit and fix the tie strap 309. The shrapnel 311 has a certain elastic deformation ability, and its structural design enables the shrapnel 311 to tightly clamp the belt tooth 310 part when the tie strap 309 is inserted under the shrapnel 311, preventing the tie strap 309 from retreating, thereby quickly realizing the limit locking of the ruler 1.

[0040] The diameter of the guide hole is matched with the size of the ruler 1 and the tie band 309, which ensures that the ruler 1 can slide axially smoothly in the hole and prevents the tie band 309 from deflecting during the pulling process. The tie band 309 has a certain rigidity and can resist the pressure and tension transmitted to the tie band by the non-rigid hose 2 through the ruler 1. The opening and closing of the spring 311 can be controlled by the torsion spring.

[0041] Example 3 Reference Figure 7 This embodiment provides a method for drawing an irregular curve, including: S1. Obtain the curve to be laid out, perform grid positioning on the curve to be laid out and form n calibration points, the spacing of the n calibration points on the horizontal line projection is consistent with the spacing of the multiple rulers 1; S2. Taking the first calibration point as the reference point, obtain the position coordinates of the remaining reference points in the y-axis direction of the lofting curve; S3. The irregular curve drawing device is placed above the template to be processed, and the scale displayed by the first ruler 1 at the contact point of the square tube 301 is used as the first calibration point. The subsequent ruler 1 is adjusted according to the position coordinates of the remaining reference points in the y-axis direction of the lofting curve, and the adjustment length is determined according to the scale displayed at the contact point between the ruler 1 and the square tube 301; S4. The non-rigid hose 2 approaches the curve to be lofted, and the curve formed by the non-rigid hose 2 is laid out on the template to be processed.

[0042] In this embodiment, n=6, the distance between two adjacent rulers 1 is 200 mm, the ruler 1 is 600 mm long, the non-rigid hose 2 is 1400 mm long, and the screw rod 302 or the cable tie 309 is 500 mm long.

[0043] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
