Technical Field
[0001] The present invention relates to a detection tool for the radian of an arc beam formwork, specifically an arc gauge and a method for detecting the radian of an arc beam formwork. Background Art
[0002] With the diversification of architectural engineering design shapes, arc beam structures are becoming more and more common. In the traditional construction process of arc beams, it is necessary to fabricate arc beam formworks with radian. The accuracy of the radian of the arc beam formwork will directly affect the forming quality of the arc beam. In the prior art, there is a lack of a detection tool for the radian of the arc beam formwork, and it is difficult to guarantee the quality of the fabricated arc beam formwork. Often, the visual quality of the formed arc concrete components is not good, resulting in an increased probability of secondary rework in the later stage. Summary of the Invention
[0003] The present invention first discloses an arc gauge, which can be used to detect the radian after the erection of the arc beam formwork to ensure that the flatness of the bending surface of the arc beam formwork meets the design requirements.
[0004] To achieve the above object, the technical solution adopted by the present invention is as follows: An arc gauge includes a horizontal connecting rod, a position adjusting rod, a fastening clip, and a measuring steel wire rope. The horizontal connecting rod includes a straight rod-shaped connecting rod body. A horizontal sliding groove is opened along the length direction on the connecting rod body. A horizontal adjusting bubble is provided in the middle of the connecting rod body. Three position adjusting rods are installed on the horizontal connecting rod. The length direction of the position adjusting rod is perpendicular to the length direction of the horizontal connecting rod. The position adjusting rod includes an adjusting slider, a threaded sleeve, a long threaded rod, a conical end, a short threaded rod, and a hexagonal rotating grip. The threaded sleeve is hollow and has internal threads. The long threaded rod passes through the threaded sleeve. The top end of the long threaded rod is fixedly installed with a hexagonal rotating grip. A threaded hole is opened at the bottom end of the long threaded rod. A scale for determining the adjustment length of the long threaded rod is provided on the long threaded rod. The conical end is fixed at the bottom of the short threaded rod. The short threaded rod is screwed into the threaded hole at the bottom of the long threaded rod for fixation. The adjusting slider is fixedly installed on the outer wall of the threaded sleeve. A through steel wire rope perforation is opened on the conical end. The position of the position adjusting rod is adjusted by the adjusting slider being embedded in the horizontal sliding groove and being able to slide along the horizontal sliding groove. The measuring steel wire rope is sequentially passed through the steel wire rope perforations between the three position adjusting rods. An anti-detachment clip is provided at the end of the measuring steel wire rope. The anti-detachment clip cannot pass through the steel wire rope perforation. A fastening clip for restricting the position of the position adjusting rod is installed on the horizontal connecting rod beside the position adjusting rod.
[0005] Further, the horizontal adjusting bubble is installed on the opposite surfaces of the horizontal sliding groove.
[0006] Further, the cross-section of the adjusting slider and the cross-section of the horizontal sliding groove are both T-shaped.
[0007] Furthermore, the outer diameter of the perforation of the wire rope is larger than the inner diameter.
[0008] Furthermore, the fastening clip includes a bolt and a nut. A plurality of threaded holes penetrating the horizontal sliding groove are formed on the connecting rod body. After the bolt passes through the threaded hole, a nut is sleeved for locking.
[0009] The present invention also simultaneously discloses a method for detecting the radian of the circular arc beam formwork by using the above-mentioned circular arc ruler, including the following steps: Step 1): According to the design drawing of the circular arc beam, first calculate and confirm the radius of the circular arc beam formwork and the horizontal length of the arc length on the drawing, and confirm whether the inner radian or the outer radian of the circular arc beam formwork is to be measured; Step 2): According to the arc length and radius marked on the drawing, measure the adjacent distances L1 and L2 between the three position adjusting rods on the drawing, and respectively measure the vertical distances L3, L4, and L5 from the bottom of the conical ends on the three position adjusting rods to the horizontal connecting rod; Step 3): Adjust the relative positions of the three position adjusting rods of the circular arc ruler, so that the distance between the left position adjusting rod and the middle position adjusting rod is L1, and the distance between the right position adjusting rod and the middle position adjusting rod is L2. After the positions of the three position adjusting rods are adjusted, use the fastening clip to limit the position of the position adjusting rod; respectively adjust the lengths of the long threaded rods of the three position adjusting rods passing through the threaded sleeves, so that the vertical distance from the bottom of the conical end of the left position adjusting rod to the horizontal connecting rod is L3, the vertical distance from the bottom of the conical end of the middle position adjusting rod to the horizontal connecting rod is L4, and the vertical distance from the bottom of the conical end of the right position adjusting rod to the horizontal connecting rod is L4; Step 4): Place the conical ends at the bottoms of the position adjusting rods of the circular arc ruler adjusted in Step 3 against the measured arc surface of the circular arc beam formwork to be measured. Adjust the horizontal adjusting bubble to make the horizontal connecting rod in a horizontal state, and then measure the gap size between the measuring wire rope and the measured arc surface of the circular arc beam formwork; Step 5): After the measurement is completed, record the gap size between the measuring wire rope and the measured arc surface of the circular arc beam formwork, and confirm whether the gap size is within the specified range according to the design requirements.

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0014] This embodiment discloses a circular arc straightedge for detecting the arc of a circular arc beam formwork, and its structure is as Figure 1 shown. It mainly includes a straight - bar - shaped horizontal connecting rod 1. Three position adjustment rods 2 are installed on the horizontal connecting rod 1. The length directions of the three position adjustment rods 2 are perpendicular to the length direction of the horizontal connecting rod 1, and the distance between the three position adjustment rods 2 is adjustable. A fastening clip 4 is also installed on the horizontal connecting rod 1 beside the position adjustment rod 2, and the fastening clip 4 is used to limit the position of the position adjustment rod 2. The three position adjustment rods 2 are sequentially connected by a measuring steel wire rope 3.
[0015] The structure of the horizontal connecting rod 1 is as Figure 2As shown in the figure, the horizontal connecting rod 1 includes a strip-shaped connecting rod body 11 with a rectangular cross-section. A horizontal sliding groove 12 is formed on one side of the connecting rod body 11 along the length direction of the connecting rod body 11. The cross-section of the horizontal sliding groove 12 is T-shaped, with a wider inner side and a narrower outer side. A horizontal adjusting bubble 13 is installed in the middle of the opposite side of the connecting rod body 11 where the horizontal sliding groove 12 is located. By observing the horizontal adjusting bubble 13, it can be known whether the connecting rod body 11 is in a horizontal state.
[0016] The structure of the position adjusting rod 2 is as Figure 3 and Figure 4 shown. The position adjusting rod 2 includes an adjusting slider 21, a threaded sleeve 22, a long threaded rod 23, a conical end 24, a short threaded rod 25 and a hexagonal rotating grip 26. The threaded sleeve 22 is a hollow cylindrical structure with internal threads provided on its inner wall. The external threads of the long threaded rod 23 match the internal threads of the inner wall of the threaded sleeve 22. The long threaded rod 23 passes through the threaded sleeve 22, and a hexagonal rotating grip 26 is fixedly installed at the top of the long threaded rod 23. There are scales on the long threaded rod 23. By holding the hexagonal rotating grip 26 and rotating the long threaded rod 23, the length of the bottom of the long threaded rod 23 extending out of the threaded sleeve 22 can be adjusted. By observing the scales, the distance from the bottom of the conical end 24 to the connecting rod body 11 can be known. A threaded hole is opened at the bottom end of the long threaded rod 23. The conical end 24 is fixed at the bottom of the short threaded rod 25. The external threads of the short threaded rod 25 match the internal threads of the threaded hole at the bottom of the long threaded rod 23, and the short threaded rod 25 is screwed into the threaded hole at the bottom of the long threaded rod 23 for fixation. An adjusting slider 21 is fixedly installed on the outer wall of the threaded sleeve 22. The cross-section of the adjusting slider 21 is T-shaped, with a wider outer side and a narrower inner side, and its shape matches the cross-sectional shape of the horizontal sliding groove 12. When installing the position adjusting rod 2, the adjusting slider 21 is slid into the horizontal sliding groove 12 from the open end on the side of the horizontal sliding groove 12, so that the position adjusting rod 2 can slide along the horizontal sliding groove 12, thereby adjusting the distance between the three position adjusting rods 2. As Figure 5 shown, a through steel wire rope perforation 241 is opened on the conical end 24, so that the measuring steel wire rope 3 passes through the steel wire rope perforation 241. The outer diameter of the steel wire rope perforation 241 is larger than the inner diameter. An anti-detachment fastener 242 is installed at the end of the measuring steel wire rope 3. The anti-detachment fastener 242 cannot pass through the steel wire rope perforation 241. The measuring steel wire rope 3 can be tightened between the three position adjusting rods 2 through the limitation of the anti-detachment fastener 242. When installing the three position adjusting rods 2, one of the position adjusting rods 2 is installed at the middle position of the connecting rod body 11, and the other two position adjusting rods 2 are respectively installed on both sides of it.
[0017] The structure of the fastening fastener 4 is as Figure 6As shown, the fastening clip 4 includes a bolt and a nut. A plurality of threaded holes penetrating the horizontal sliding groove 12 are formed in the connecting rod body 11. After the position of each position adjusting rod 2 on the connecting rod body 11 is adjusted, a bolt is inserted into the threaded hole adjacent to the side of the position adjusting rod 2, and then the nut is sleeved on the bolt from the other side and tightened, so as to limit the position of the position adjusting rod 2.
[0018] The arc template ruler designed by the present invention can be used to detect the outer arc of the arc beam formwork and the inner arc of the arc beam formwork. When used for the former detection, as Figure 8 shown, the lengths of the long threaded rods 23 of the three position adjusting rods 2 passing through the bottom of the threaded sleeves 22 are respectively adjusted, so that the length of the long threaded rod 23 of the position adjusting rod 2 located in the middle passing through is shorter than the lengths of the long threaded rods 23 of the position adjusting rods 2 on both sides, making the measuring steel wire rope 3 present a Figure 8 state of bending upward between the three position adjusting rods 2 as shown. When used for the latter detection, as Figure 7 shown, the length of the long threaded rod 23 of the position adjusting rod 2 located in the middle passing through is longer than the lengths of the long threaded rods 23 of the position adjusting rods 2 on both sides, making the measuring steel wire rope 3 present a Figure 7 state of bending downward between the three position adjusting rods 2 as shown.
[0019] When using the above arc template ruler designed by the present invention to detect the arc of the arc beam formwork, the detection method is described as follows. For the sake of simplicity, the following takes the detection of the outer arc of the arc beam formwork as an example for display (refer to Figure 9 shown), and for the detection of the inner arc of the arc beam formwork, the following content can be referred to.
[0020] Step 1): According to the design drawing of the arc beam, first calculate and confirm the radius R of the arc beam formwork 5 and the horizontal length of the arc length on the drawing, and confirm whether the arc to be measured is the inner arc or the outer arc of the arc beam formwork 5. In this embodiment, the outer arc is taken as an example for measurement; Step 2): According to the arc length and radius marked on the CAD drawing of the arc beam, measure the lengths of Figure 9 L1, L2, L3, L4, and L5 shown in the drawing; Step 3): According to the lengths of L1, L2, L3, L4, and L5, adjust the positions of the three position adjusting rods 2 on the horizontal connecting rod 1 and the lengths of the long threaded rods 23 passing through the threaded sleeves 22; Specifically, as Figure 9As shown, the straight line EF can be corresponded to the position of the horizontal connecting rod 1. Move the position adjusting rod 2 in the middle to the position D, and fix its position by installing fastening clips 4 on both sides. Then rotate the hexagonal rotary grip 26 to adjust the protruding length of the long threaded rod 23, so that the vertical length from the bottom of the conical end 24 of the middle position adjusting rod 2 to the connecting rod body 11 is L4. Move the position adjusting rod 2 on the left to the position E, and make the distance ED be L1. Move the position adjusting rod 2 on the right to the position F, and make the distance DF be L2. Adjust the protruding lengths of the long threaded rods 23 of the position adjusting rods 2 on the left and right respectively, so that the vertical length from the bottom of the conical end 24 on the left to the connecting rod body 11 is L3, and the vertical length from the bottom of the conical end 24 on the right to the connecting rod body 11 is L5. Similarly, after the positions of the position adjusting rods 2 on the left and right are adjusted, the position adjusting rods 2 on the left and right need to be limited by the fastening clips 4 respectively; Step 4): Use the adjusted arc template gauge to measure the required arc beam formwork 5, adjust the horizontal adjusting bubble 13 to ensure that the connecting rod body 11 is in a horizontal state. Figure 9 Points B, A, and C on the Figure 9 are three points on the outer arc of the arc beam formwork 5. The bottoms of the conical ends 24 of the three position adjusting rods 2 can be made to respectively lean against the above three points of the arc beam formwork 5. If the radian of the arc beam formwork 5 after erection completely conforms to the design drawing, the bent shape formed by the measuring steel wire ropes 3 between the three position adjusting rods 2 should completely fit the outer arc surface of the arc beam formwork 5. Otherwise, there will be a gap between the bent shape formed by the measuring steel wire ropes 3 and the outer arc surface of the arc beam formwork 5. At this time, it is necessary to determine the size of the gap between the measuring steel wire ropes 3 on the arc template gauge and the outer arc surface of the arc beam formwork 5; Step 5): After the measurement is completed, record the size of the gap between the measuring steel wire ropes 3 and the outer arc surface of the arc beam formwork 5. According to the design requirements, confirm whether this gap is within the specified range, and then it can be known whether the fabrication of the arc beam formwork 5 meets the design requirements.
