Description

Technical Field

[0001] The present invention relates to the field of curved surface modeling space construction, and in particular to a jacking device positioning method for complex curved surface modeling space construction. Background Art

[0002] When constructing a curved surface space, it is generally necessary to build a skeleton, through which the basic shape of the curved surface is constructed. The skeleton needs to be supported below. Traditional skeletons are all rigid structures, and supports can be set by selecting nodes below the rigid skeleton.

[0003] At present, in order to realize the complexity and diversification of curved surface modeling, there are non-rigid skeleton forms, such as mesh structures, which form sheets through the connection between several nodes, and the sheets form surfaces. There is a certain deformation between the nodes when they are connected; the support must meet the needs of modeling and have a load-bearing effect. Traditional support methods cannot meet the requirements. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method for positioning a jacking device for constructing a complex curved surface modeling space, which supports and positions the node positions of the curved surface modeling skeleton. The technical objectives of the present invention are achieved through the following technical solutions:

[0005] A method for positioning a jacking device for constructing a space with a complex curved surface is disclosed. The method is based on a jacking device consisting of a bottom support and a top support. The top support is installed above the bottom support and includes a support plate. The support plate is a polygonal flat plate and can be adjusted in height and angle relative to the bottom support. The method comprises the following steps:

[0006] S1. Before positioning the lifting device, a curved surface modeling space model is constructed in a 3D modeling software to determine the 3D coordinates of each node position in the curved surface modeling space, and the node positions are placed at the corners of the support plate;

[0007] S2. Draw a plane grid diagram of the surface modeling space model in 3D modeling software based on the node projection, and lay out lines on the construction ground according to the drawn plane grid diagram to obtain a construction grid;

[0008] S3. Place several jacking devices in the construction grid according to the construction grid diagram drawn by ground layout, and adjust the position of the jacking devices according to the three-dimensional coordinates of each node.

[0009] Furthermore, the position adjustment of the jacking device includes the position adjustment of the bottom support and the top support; first, the position of the bottom support in the construction grid is adjusted according to the three-dimensional coordinates of the node, and then the height and angle of the support plate are adjusted according to the three-dimensional coordinates of the node.

[0010] Furthermore, the top support also includes a connecting support column and a spherical shaft. The spherical shaft is installed at the lower end of the support plate. The lower end of the support column is vertically installed above the bottom support. The upper end of the support column is connected to the bottom of the support plate through the spherical shaft. The length of the support column is adjustable; the height of the support plate is adjusted by adjusting the length of the support column, and the support plate is rotated relative to the support column to achieve angle adjustment of the support plate.

[0011] Furthermore, a positioning support is provided above the bottom support, and the lower end of the positioning support is installed and fixed above the bottom support. The upper end of the positioning support is a free end, and the length of the positioning support can be adjusted. The length of the positioning support is adjusted so that the upper end of the positioning support is against the lower end surface of the support plate, and the angle of the support plate is positioned by the positioning support.

[0012] Furthermore, a moving wheel is provided at the lower end of the bottom support.

[0013] Furthermore, the bottom support includes several sections of support units, and the support unit includes at least one, and the support units of the same bottom support are stacked.

[0014] Furthermore, the number of support units is selected according to the longitudinal coordinates of the three-dimensional coordinates of the nodes.

[0015] Furthermore, while the bottom support position is moved horizontally, the plane coordinates of the corner positions of the support plate are measured with the help of a total station until the plane coordinates of the corner positions of the support plate meet the plane coordinates of the position node.

[0016] Furthermore, after the position of the bottom support is positioned, the angle of the support plate is adjusted, and the height of the corner positions is adjusted one by one. The longitudinal coordinate of one of the corners of the support plate is measured by a total station so that the longitudinal coordinate of the corner position is equal to the longitudinal coordinate of the position node. After the adjustment of one corner position is completed, the length of the positioning support close to the corner position is adjusted so that the upper end of the positioning support is against the lower end of the support plate; then the height of the remaining corner positions is adjusted according to this method.

[0017] Furthermore, the support plates are spliced into a surface. After positioning is completed, check whether there is warping between the adjacent support plates at adjacent positions. If so, the angle of the support plate at that position needs to be readjusted.

[0018] Compared with the existing technology, the beneficial effect of the present invention is that the jacking device is positioned by the positioning method of the present invention, and finally the support surface is formed by connecting the support plates at the construction site, and subsequent construction can be carried out directly on the support surface, which can meet the effect of non-rigid skeleton support and the effect of non-rigid skeleton positioning; finally, the non-rigid skeleton is installed on the support surface, which reduces the difficulty of installation.

[0023] The technical solution of the present invention is further described below in conjunction with specific embodiments:

[0024] A method for positioning a jacking device for constructing a complex curved surface modeling space is provided, which is used for positioning and supporting a non-rigid skeleton in the construction of a complex curved surface modeling space. The jacking devices are arranged in an array to ultimately form a skeleton support surface, and a skeleton is erected on the skeleton support surface.

[0025] The jacking device includes two parts: bottom support 1 and top support. Figure 2 As shown, the top support is installed above the bottom support 1; the top support includes a support plate 6, a support column 3, a spherical shaft 5, and a positioning support 4. The spherical shaft 5 is installed at the lower end of the support plate 6, and the lower end of the support column 3 is vertically installed at the upper end of the bottom support 1. The upper end of the support column 3 is connected to the spherical shaft 5. The support column 3 is connected to the support plate 6 through the spherical shaft 5. The support plate 6 can be adjusted in angle relative to the support column 3; a number of positioning supports 4 are arranged on the periphery of the support column 3. Taking four positioning supports 4 as an example, the lower ends of the four positioning supports 4 are vertically installed at the upper end of the bottom support 1, and the upper ends of the positioning supports 4 are free ends. The length of the positioning supports 4 can be adjusted. By adjusting the length of the positioning supports 4, the free ends of the positioning supports 4 can be pressed against the support plate 6 from below, thereby realizing the angular positioning of the support plate 6. The support plate 6 is a polygonal flat plate, such as a quadrilateral, a triangle, etc. Several lifting devices are arranged in an array, and finally the support plates 6 are spliced to form a support surface, such as Figure 3 As shown, the corner positions of the support plate 6 form nodes 10 .

[0026] The length of the support column 3 is adjustable. In this embodiment, the support column includes two sections, which are connected by a socket joint. Both sections are provided with a limit hole 8. The lower support column is connected to and fixed to the bottom support, and the upper support column is connected to and fixed to the spherical shaft 5. The upper support column can be moved up or down relative to the lower support column to achieve height adjustment. After the adjustment is completed, a limit pin 9 can be inserted into the limit hole 8 to temporarily fix the position of the upper and lower support columns. Similarly, the positioning support can also include two sections, which are distributed up and down. The two sections of the positioning support are provided with a socket joint. The lower positioning support is connected and fixed to the upper end of the bottom support. The upper positioning support can be moved up or down relative to the lower positioning support. The two sections of the positioning support are also provided with a limit hole 8. The limit pin 9 is inserted into the limit hole 8. The relative position of the upper and lower limit columns is temporarily fixed by inserting the limit pin 9 into the limit hole 8. Of course, the positioning support and the support column can also use electric telescopic motors, hydraulic cylinders, cylinders, etc., but the relative cost will be increased.

[0027] The bottom support 1 is composed of several sections of support units 7, such as Figure 3 As shown, it includes at least one support unit 7, such as a steel frame or a scaffolding; the support units 7 are stacked as needed, and the support units are connected and fixed to form a whole; in order to facilitate movement, moving wheels 2 can also be installed under the bottom support, and the bottom support can be directly pushed to adjust the horizontal position during use.

[0028] The following steps are included during adjustment:

[0029] S1. Before positioning the lifting device, create a 3D model of the curved surface space in 3D modeling software, such as Rhino or SketchUP. Determine the 3D coordinates (X, Y, Z) of each node position in the 3D modeling software. The coordinates of the node are the coordinates of the corner positions of the final support plate. Taking a quadrilateral support plate as an example, there is a node at each corner of the quadrilateral support plate, and each node position has a determined 3D coordinate (x1, y1, z1), (x2, y2, z2), (x3, y3, z3), and (x4, y4, z4).

[0030] S2. Draw a plane grid diagram of the curved surface modeling space in 3D modeling software based on the node projections, projecting each node from top to bottom, and connecting the node projections of each node in the plane to form a plane grid diagram of the curved surface modeling space; and lay out the lines at the construction site based on the plane grid diagram to draw a construction grid;

[0031] The required number of support units is determined based on the longitudinal coordinate Z of the jacking device at each grid position to ensure that the height of the support plate is close to the longitudinal coordinate Z of the node after the support units are stacked. The height of the support plate is then fine-tuned through the support columns.

[0032] S3. According to the construction grid, the corresponding jacking device is initially moved into the grid, and each jacking device is adjusted horizontally according to the plane coordinates (X, Y) of the node; the horizontal coordinates of the four corners of the support plate are measured with the help of a total station, and the jacking device is moved so that the horizontal coordinates of the four corners of the support plate meet the plane coordinates of the grid position node.

[0033] After the horizontal position adjustment is completed, adjust the height and angle of the support plate:

[0034] Adjust the heights of the four corners of the support plate one by one, measure the height coordinates of a corner with the help of a total station, and the height and angle of the support plate can be adjusted freely. Keep adjusting the coordinates of the corner until the longitudinal coordinates of the node corresponding to the corner are met, and then adjust the height of the positioning support close to the position so that the upper end of the positioning support is against the lower end face of the support plate, and then insert the limit pin to fix the positioning support at that position; then determine the heights of the other corners in the same way, and after the heights of the four corners are determined, the angle adjustment of the support plate is completed; when the height adjustment of the four corners of the support plate is completed, limit the height of the support column by the limit pin to complete the positioning of a jacking device.

[0035] Complete the positioning of the remaining jacking devices according to the above method. After completion, you can also check the support surface of the spliced support plates, mainly to observe whether there is a warping problem between adjacent support plates. If not, it means that the positioning is accurate. If there is warping, there is a problem with the angle positioning of the support plate of the positioning support at that position, and it needs to be readjusted.

[0036] This embodiment is only a further explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
