Description

Technical Field

[0001] The utility model belongs to the technical field of construction measurement, and in particular relates to a high pier template verification measurement auxiliary device for square piers, polygonal piers, hollow thin-walled piers and the like under the highway bridge. Background Art

[0002] The intersection angles of high pier structures such as the lower structure, square piers, hollow thin-walled piers in highway bridge projects are generally designed with round chamfers. During the round chamfering construction, round chamfer templates or polygonal templates and other bridge high pier templates are used. The bridge high pier templates have a designed position, and the template plane position and elevation need to be adjusted to the designed position before the next construction process can be carried out.

[0003] In actual projects, high precision control is required for the installation position of bridge pier formwork. When installing bridge pier formwork such as rounded chamfer formwork or polygonal formwork, measurement and layout are required to ensure that the installation position of the bridge pier formwork is consistent with the design position or design elevation of the formwork.

[0004] In the prior art, two methods are usually used in the process of measuring and setting out the fillet template: the first method is to extend the two straight edges of the fillet to intersect at a point on the template; the second method is to check the point where the fillet straight line and the arc meet, and convert a fillet into two points, where the two points refer to a point where each end of the arc meets the fillet straight line. The first method can directly measure and check the position of the intersection, but it can only measure fillets with small radius. When the fillet radius is too large, the accuracy is not high, and the surveyor needs to stand on the template to hold the prism to increase the risk of safe operation. Although the second method does not require measuring the intersection, it increases the measurement workload. A square pier template includes four fillets, which requires checking eight points. Sometimes the line of sight is easily affected, and multiple measurements are required, which is slow in efficiency. Therefore, it is urgent to propose a verification device to facilitate the verification of whether the position of the bridge high pier template is consistent with the design elevation.

[0040] In the first embodiment, if Figure 2 As shown, the bridge high pier template 6 adopts a round chamfer template. The template is pre-assembled first, and the staff stands on the scaffolding or working platform, and moves the movable plate 3 to rotate the movable plate 3 clockwise or counterclockwise, so as to place the utility model device on the periphery of the round chamfer template. Specifically, the side of the fixed plate 4 and the fixed magnetic block 5 are in contact with and connected to one side of the round chamfer template, and the fixed magnetic block 5 is adsorbed on the said side of the round chamfer template by magnetic force, and the movable plate 3 is in contact with and connected to the other side of the round chamfer template. The bottom surface of the round chamfer template is flush with the lower surface of the fixed plate 4. The staff stands on the scaffolding or working platform to level the centering base 2 to make the measurement auxiliary device horizontal and vertical. The elevation h0 of the center of the Leica circular prism 1 is read by the Leica total station. The elevation in the utility model refers to the absolute elevation of the measured object relative to the construction elevation control network. The height difference h1 from the center of the Leica circular prism 1 to the top surface of the centering base 2 is a known number, and the height difference h2 between the top surface of the centering base 2 and the bottom surface of the fixed plate 4 is a known number. The elevation of the round chamfer template h = h0-h1-h2, and the h0 value is compared with the design elevation of the round chamfer template to see if it is consistent. The utility model measures the coordinates of the intersection of the two straight lines of the round chamfer template, compares the difference between the measured coordinates and the design coordinates, and adjusts the position of the round chamfer template until it meets the specification requirements before the next process can be carried out.

[0041] The second embodiment of the utility model: the 360° prism is a type of Leica prism, such as Figure 3 As shown, the Leica prism uses a 360° prism.

The movable plate 3 can rotate clockwise or counterclockwise in the horizontal direction around the lower section of the vertical side 91. The top of the connecting line 10 is connected to the bottom side 92 and the connecting line 10 is arranged vertically downward along the direction of the vertical side 91, and the bottom end of the connecting line 10 is connected to the 360° prism 8.

[0046] In the utility model, the main function of the rectangular connector is to ensure that the 360° prism below is on the same plumb line with the center point of the centering base. By hanging the 360° prism, the elevation of the 360° prism of the Leica total station installed on a distant working platform is used to further check the elevation of the high pier formwork of the bridge, thereby avoiding the problem that the elevation angle of the tall formwork is too large and the line of sight is blocked during the layout process and is difficult to check.

[0047] In the second embodiment, i.e., using a 360° prism, the method of using the device of the utility model is as follows:

[0048] In the second embodiment, the bridge high pier template 6 adopts a polygonal template. The polygonal template is first pre-installed in a position according to experience. The staff stands on the scaffolding or working platform and moves the movable plate 3 to rotate the movable plate 3 clockwise or counterclockwise so as to place the device of the utility model on the periphery of the polygonal template. Specifically, the side of the fixed plate 4 and the fixed magnetic block 5 are in contact with one side of the polygonal template, and the fixed magnetic block 5 is adsorbed on one side of the polygonal template by magnetic force, and the movable plate 3 is in contact with the other side of the polygonal template. The staff stands on the scaffolding or working platform to level the centering base 2 so that the measurement auxiliary device is horizontal and vertical. The elevation h0 of the 360° prism is observed by the Leica total station, the length h1 of the connecting line 10 is known, the vertical distance h2 from the bottom edge 92 of the rectangular connector to the vertex of the centering base 2 is known, there is a fixed height difference h3 between the vertex of the centering base 2 and the bottom surface of the fixed plate 4, the lower surface of the polygonal template is flush with the lower surface of the fixed plate 4, the top of the connecting line 10 is connected to the bottom surface of the bottom edge 92 and the connecting line 10 is arranged vertically downward along the direction of the vertical edge 91, so the elevation h of the polygonal template is h=h0+h1+h2-h3. By observing the measured coordinates of the 360° prism and comparing the difference between the measured coordinates and the designed coordinates, the polygonal template is adjusted until it meets the specification requirements before the next construction process can be carried out.
