Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to an adjustable radius arc-shaped template measuring and layout tool. Background Technology

[0002] Arc-shaped structures are widely used in various types of buildings due to their unique form. Specifically, arc-shaped structures include cylindrical columns and curved beams. However, the practice of measuring and setting out arc-shaped formwork for cylindrical columns and beams, floor slabs, and curved beams is less common, as the setting-out process is quite cumbersome. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, an adjustable radius arc-shaped formwork measurement and layout tool is provided to solve the problem that the measurement and layout of arc-shaped formwork for columns, beams, floor slabs, and curved beams is rarely used and the layout steps are relatively cumbersome.

[0004] To achieve the above objectives, an adjustable radius arc-shaped template measuring and layout tool is provided, comprising:

[0005] An arc-shaped elastic board, the elastic board having an inner arc surface and an outer arc surface opposite to each other;

[0006] At least five support plates are provided, the support plates are connected to the outer arc surface of the elastic strip plate, the multiple support plates are equally spaced along the arc line of the elastic spring board, the support plates are respectively provided at both ends of the elastic strip plate, and the remaining support plates are provided with through holes.

[0007] The tension cable is movably threaded through the holes in the remaining support plates, and the two ends of the tension cable are respectively connected to the support plates at both ends of the elastic strip plate.

[0008] The tightening structure includes a spool and a locking member for locking the spool. A support plate has a shaft hole that communicates with a through hole. The spool is rotatably inserted through the shaft hole. One end of the spool extends into the through hole and is connected to the tension cable. The locking member is installed on the support plate. After the spool is rotated, the tension cable is wound around the spool to shorten the tension cable, thereby reducing the central angle corresponding to the elastic strip.

[0009] At least two lasers are provided. The inner arc surface of the elastic strip has multiple mounting holes arranged along the arc direction of the elastic strip. The multiple lasers are respectively installed in the multiple mounting holes. The laser beams emitted by the lasers are perpendicular to the inner arc surface. The intersection of the laser beams of the at least two lasers is the center of the elastic strip.

[0010] Furthermore, the other end of the spool extends to the outside of the support plate and is coaxially connected to a turntable. The turntable has a plurality of first locking holes, and the support plate has a second locking hole. The locking member is detachably inserted into a first locking hole and a second locking hole.

[0011] Furthermore, the plurality of first locking holes are arranged along the circumferential direction of the turntable.

[0012] Furthermore, the plurality of first lock holes are arranged at equal intervals.

[0013] Furthermore, the support plate is centrally located in the middle of the elastic strip.

[0014] The beneficial effect of the present invention is that the adjustable radius arc template measuring and layout tool of the present invention can adjust the curved surface of the elastic strip plate into an arc surface with different radii by rotating the roller on the back of the elastic strip plate. According to the shape of the arc surface, the template is measured and laid out, thereby achieving the effect of making arc templates with different radii, saving the measurement and layout steps and processes of arc templates.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Reference Figure 1 and Figure 2 As shown, the present invention provides an adjustable radius arc-shaped template measurement and layout tool, including: an elastic strip 1, a support plate 2, a tension cable 3, a tightening structure 4, and a laser 5.

[0021] The elastic strip 1 is a long, strip-shaped, and elastic plate. The elastic strip 1 is arc-shaped and has an inner arc surface and an outer arc surface. It also has two opposite ends along its arc direction.

[0022] The number of support plates 2 is at least five. In this embodiment, as... Figure 1 As shown, there are five support plates 2. In some embodiments, the support plates are arranged more densely. The support plates 2 are connected to the outer arc surface of the elastic strip plate 1. The multiple support plates 2 are arranged at equal intervals along the arc line of the elastic strip plate. Support plates 2 are respectively provided at both ends of the elastic strip plate 1. The remaining support plates 2 have through holes. The distance from the through holes of the multiple support plates to the elastic strip plate is equal.

[0023] The tension cable 3 is movably threaded through the holes in the remaining support plates 2. The two ends of the tension cable 3 are respectively connected to the support plates 2 at both ends of the elastic strip 1.

[0024] The tightening structure 4 includes a spool 41 and a locking element for locking the spool 41. A support plate 2 has a shaft hole. The shaft hole communicates with a through hole. The spool 41 is rotatably inserted through the shaft hole. One end of the spool 41 extends into the through hole and is connected to the tension cable 3. The locking element is mounted on the support plate 2.

[0025] After rotating the spool 41, the tension cable 3 is wound around the spool 41 to shorten the tension cable 3, so that the curled elastic strip gradually unfolds, that is, the central angle corresponding to the elastic strip 1 becomes smaller.

[0026] The number of lasers 5 is at least two. In this embodiment, the inner arc surface of the elastic strip 1 has multiple mounting holes. The multiple mounting holes are arranged along the arc direction of the elastic strip 1. The multiple lasers 5 are respectively mounted in the multiple mounting holes. The laser beams 51 emitted by the lasers 5 are perpendicular to the inner arc surface. The intersection point O of the laser beams 51 of at least two lasers 5 is the center of the elastic strip 1.

[0027] See Figure 2 As shown, in this embodiment, the other end of the spool 41 extends to the outside of the support plate 2 and is coaxially connected to a turntable 42. The turntable 42 has a plurality of first locking holes 420. The support plate 2 has a second locking hole. A locking member is detachably inserted into one of the first locking holes 420 and the second locking hole.

[0028] In a preferred embodiment, a plurality of first locking holes 420 are arranged along the circumferential direction of the turntable 42. Furthermore, in this embodiment, the plurality of first locking holes 420 are arranged at equal intervals.

[0029] In this embodiment, the tightening structure is disposed on a support plate 2, which is centrally disposed in the middle of the elastic strip 1.

[0030] The adjustable radius arc template measuring and layout tool of the present invention adjusts the curved surface of the elastic strip plate into arc surfaces of different radii by rotating the roller on the back of the elastic strip plate. According to the shape of the arc surface, the template is measured and laid out, thereby achieving the effect of producing arc templates of different radii.

[0031] This invention relates to an adjustable radius arc-shaped template measuring and layout tool. Addressing the issue of inconsistent required radii for arcs on-site, the tool uses a scroll on its back to adjust the curved surface into arcs of different radii. The elastic strip is made of a highly resilient material and is normally arc-shaped. By rotating the scroll, the curved surface of the elastic strip is stretched open; when the scroll is rotated in the opposite direction, the elastic strip, due to its inherent resilience, evolves from a straight state to a bent state.

[0032] During the measurement and layout process, the adjustable radius arc template of the present invention, which has been adjusted according to the radius, is used to measure and lay out the line. The center position is found by the intersection of the laser beams of multiple lasers of the layout tool. The arc position is located by the center position. Finally, the arc is laid out according to the elastic strip.

[0033] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
