[0015] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0016] Please see Figures 1-4 A measuring and positioning fixture for the construction of curved stone curtain walls includes a curved ruler 1 concentric with the curved exterior wall 10, with a radius at least 2 cm different from the finished surface of the stone curtain wall. At least three scales 2 are provided on the curved ruler 1, arranged in a horizontal plane and corresponding one-to-one with three sequentially arranged curtain wall embedded plates 9, extending radially and connected to the curved ruler 1 via ring buckles 3. The ring buckles 3 have a fixing sleeve adapted to the curved ruler 1 and an mounting sleeve adapted to the scales. The mounting sleeve has a scale set screw 4, and the fixing sleeve has a ring set screw 5. A level 6 is installed on the curved ruler 1, fixed with bolts 7, for checking the level of the curved ruler.

[0017] The more preferred solution in this embodiment is as follows:

[0018] The arc-shaped scale 1 is made of a solid cylinder with a beveled top to facilitate a tight connection with the ring 3 and ensure that the three scales 2 are always coplanar.

[0019] The length of the arc-shaped ruler 1 is greater than or equal to 2.2 times the spacing of the curtain wall embedded plate 9, and the structure is stable and easy to use.

[0020] The scale 2 adopts a solid rod-shaped structure, which has good rigidity and facilitates the improvement of the measurement and positioning accuracy of the tooling.

[0021] The scale 2 has a pointed tip for easy positioning.

[0022] Taking an outdoor curtain wall as an example, this utility model is applied in such a way that the radius of the arc-shaped ruler is 2cm different from that of the finished surface of the stone curtain wall.

[0023] Step 1: Calculate the distance from stone 11 to curved exterior wall 10 according to the curtain wall node design drawings. Adjust the scale and tighten the set screw 4 so that the length of the scale 2 is equal to the distance from curved exterior wall 10 to stone 11 plus 2 cm, and record it as h.

[0024] Step 2: Use this tool to measure around the top of the curved outer wall 10, measure the error between the actual and theoretical h distance on site, and take the average value as the adjusted H. Use this as the benchmark for measurement and positioning.

[0025] Step 3: Adjust the length of all three rulers 2 to H. Use this tooling to lay out the center position of the topmost curtain wall embedded plate 9 of the stone 11 and mark it, until all the topmost curtain wall embedded plates 9 are laid out. During the laying out process, the curved ruler 1 should be leveled, and the laying positions should be connected end to end. If the actual measured distance of the ruler 2 is greater than H during the laying out process, the connecting piece between the curtain wall embedded plate 9 and the main keel 8 in this part needs to be lengthened. If the actual measured distance of the ruler 2 is less than H, the curved exterior wall 10 in this part needs to be chiseled away to meet the length H.

[0026] Step 4: Following the layout points from Step 3, use a plumb line from top to bottom and a ruler to lay out the positions of the lower curtain wall embedded plates 9 one by one.

[0027] Step 5: Adjust the length of scale ruler 2 to G, G = H - (thickness of main keel + thickness of embedded plate), lay out the finished surface position of main keel 8, and construct main keel 8 so that its finished surface meets the curvature requirements of the curtain wall.

[0028] Step 6: Adjust the length of scale ruler 2 to F, where F = G - the thickness of the secondary keel. Lay out the finished surface position of the secondary main keel 12 and construct the secondary main keel 12 so that its finished surface meets the curvature requirements of the curved curtain wall.

[0029] Step 7: Adjust the length of scale 2 to E, where E = F - the thickness of the hanging piece, and calibrate and check whether the position of the back bolt hanging piece 13 meets the curvature requirements of the stone.

[0030] Step 8: When installing stone 11, adjust the length of scale ruler 2 to D, where D = E - the thickness of the stone. After the installation is completed, check and calibrate the flatness of the stone 11 to ensure it meets the design and specification requirements.

[0031] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
