The disc buckle support is arranged in the space between the foundation cross section object JC2 and the formwork system MBX to support the formwork system MBX, thereby constructing the bridge main beam. Figure 3 In the bridge cross section arrangement diagram shown in the figure, the formwork system MBX is arranged at the bottom of the bridge main beam cross section HDM, and the foundation cross section object JC2 is arranged at the ground below the bridge. The disc buckle support is arranged in the space between the foundation cross section object JC2 and the formwork system MBX to support the formwork system MBX, thereby constructing the bridge main beam.

[0039] As shown in the figure, the disc buckle support cross section object group includes the foundation cross section object JC2, the disc buckle vertical rod object LG, the disc buckle horizontal rod object SPG, the disc buckle inclined rod object XG and the formwork system MBX, which collectively express the transverse arrangement of the disc buckle support.

The formwork system MBX includes the bottom form object, the small ridge object and the large ridge object. Figure 6 Secondly, the disc buckle vertical rod object of the present application has the following basic characteristics:

[0042] (1) As shown in the figure, the disc buckle vertical rod object LG is arranged in the space between the foundation longitudinal section object JC1 and the formwork system MBX, and is used to support the formwork system MBX, thereby constructing the bridge main beam QLLM.

[0043] Figure 20 ​​As shown, the disc buckle vertical rod object is a graphic symbol object of the disc buckle vertical rod arrangement considering the rod arrangement scheme and composed of different specifications of vertical rods L2, adjustable supports L1 and adjustable bases L5. The graphic symbol shows the symbol feature lines of the adjustable supports L1, the symbol feature lines of the adjustable bases L5 and the symbol feature lines of the vertical rods L2 with disc buckle nodes L3 of various specifications. The boundary line L4 is a boundary mark between different specifications of disc buckle vertical rods.

[0044] (2) Selecting the disc buckle support cross-section object group or the disc buckle vertical rod object group composed of a plurality of disc buckle vertical rod objects, the contained disc buckle vertical rods can be automatically lengthened or a certain disc buckle vertical rod can be trimmed to the base longitudinal section object JC1 or the base cross-section object JC2 through button operation on the preset operation interface, and the automatic rod arrangement operation of the disc buckle vertical rod is completed.

[0045] (3) The horizontal alignment operation mode of the disc buckle node is as follows: Figure 19 Before the disc buckle node horizontal alignment operation in the (a) figure, the disc buckle nodes JD2 on the disc buckle vertical rod objects in the disc buckle vertical rod object group LGZ arranged on the base longitudinal section object JC1 are not at the same horizontal height as the disc buckle node JD1 on the reference disc buckle vertical rod object JLG at the leftmost side. Through button operation on the preset operation interface, the disc buckle nodes JD2 on the disc buckle vertical rod objects in the disc buckle vertical rod object group LGZ can be horizontally aligned with the disc buckle node JD1 on the reference disc buckle vertical rod object JLG, and the disc buckle vertical rod object group LGZ1 with the disc buckle nodes JD2 at the same horizontal height as the disc buckle node JD1 on the reference disc buckle vertical rod object JLG is obtained as shown in the (b) figure. Figure 19

[0046] Three, the disc buckle horizontal rod object involved in the present application is a graphic symbol object expressing the disc buckle horizontal rod in the disc buckle support, and the two endpoints are connected with the disc buckle nodes. The disc buckle horizontal rod in the disc buckle vertical rod object group can be generated in a single drawing or batch drawing manner.

[0047] Four, the disc buckle inclined rod object involved in the present application is a graphic symbol object expressing the disc buckle inclined rod in the disc buckle support, and the two endpoints are connected with the disc buckle nodes. The disc buckle inclined rod in the disc buckle vertical rod object group can be generated in a single drawing or batch drawing manner.

[0048] Five, the mileage position line object involved in the present application has the following basic features:

[0049] ​(1) Mileage position line object is a reference plumb line for marking the mileage of the vertical rod object facade arrangement. The vertical rod object with mileage attribute information in the disc buckle support plane object is automatically arranged in the bridge facade arrangement according to the mileage reference of the mileage position line object.

[0050] (2) The attribute information of the mileage position line includes the name of the line plane center line and the facade arrangement mileage of the disc buckle vertical rod object, and the attribute information can be modified on the preset operation interface.

[0051] (3) The generation mode is to draw a plumb line at a certain position on the bridge facade arrangement, and then forcibly convert it to obtain the mileage position line object.

[0052] Six, the disc buckle support plane object involved in the present application has the following basic characteristics:

[0053] (1) As shown in Figure 7 , the disc buckle support plane object is a graphic symbol object formed by the horizontal arrangement of the disc buckle horizontal rod axis SPG1, the vertical disc buckle horizontal rod axis SPG2 and the projection of the disc buckle vertical rod on the horizontal plane, which is used to express the plane arrangement scheme of the disc buckle support in a certain area on the line plane center line. The small dots at the intersection of the grid of the disc buckle support are the vertical rod plane LGPM representing the setting position of the disc buckle vertical rod. The horizontally arranged disc buckle horizontal rod axis SPG1 is referred to as "horizontal horizontal rod"; the vertically arranged disc buckle horizontal rod axis SPG2 is referred to as "vertical horizontal rod".

[0054] (2) As shown in Figure 8 , a Cartesian coordinate system XOY is provided on the disc buckle support plane object, and the coordinate origin O is the center point of the disc buckle plane, which is also referred to as the base point of the disc buckle support plane object. The coordinate system XOY can be displayed or not displayed; when displayed, it is an explicit coordinate system; if not displayed, it is an implicit coordinate system. When the design requires the disc buckle support plane object to be arranged on the line plane center line object XLZX associated with it, the base point of the disc buckle support plane object can be on the line plane center line or on the left or right side of the line plane center line, which indicates that the disc buckle support plane object has base point offset. When the base point is not on the line plane center line object XLZX, the foot point of the base point to the line plane center line object XLZX is the center pile point O1 corresponding to the base point, and the mileage of the center pile point O1 is the base point mileage of the disc buckle support plane object. The horizontal distance from the base point to the line plane center line object is referred to as the base point offset distance.

[0055] (3) The X-axis direction of the XOY coordinate system of the disc-buckle bracket plane object arranged on the centerline object XLZX of the line plane is consistent with the direction of the tangent QX of the center pile point O1 on the centerline object XLZX of the line plane.

[0056] (4) The attribute information of the disc-lock bracket plane object includes the name of the associated line plane centerline, the longitudinal and lateral spacing of the disc-lock uprights, the base point offset distance, the base point mileage, etc. Through the preset operation interface of the disc-lock bracket plane object, these attribute information can be modified, and the disc-lock bracket plane object can be automatically placed at the corresponding position of the line plane centerline associated with the name of the line plane centerline.

[0057] (5) The disc buckle bracket plane object can be moved to the desired position. Then, by operating the button on its preset operation interface, the base point mileage of the disc buckle bracket plane object is automatically modified according to the center point mileage of the associated line plane centerline object corresponding to the base point, and the disc buckle bracket plane object is automatically placed at the position of the line plane centerline.

[0058] Figure 9 The dashed line represents the disc-mount bracket plane object PKPM1, obtained through movement or geometric copying. Its base point O is perpendicular to the centerline object of the line plane, with the center stake point O2 as the perpendicular point. On the preset operation interface, button operations automatically modify the base point mileage information of the disc-mount bracket plane object based on the corresponding center stake point mileage, and automatically place the disc-mount bracket plane object at the position of the line plane centerline, forming the disc-mount bracket plane object PKPM2, represented by a solid line. Its base point O1 is still offset from the line plane centerline object, but the center stake point corresponding to base point O1 is still O2.

[0059] (6) For example Figure 10 As shown, when the longitudinal dimension of the disc buckle bracket plane object is relatively long, a straight line segment ZX can be drawn to intersect with the horizontal bar on the disc buckle bracket plane object to mark a local area of ​​the disc buckle bracket. The longitudinal spacing of the disc buckle bracket plane object in the local area can be modified on the preset operation interface, while the longitudinal spacing of other areas can remain unchanged.

[0060] (7) There can be multiple line plane centerline objects in a graphic page, and multiple disc buckle bracket plane objects can be arranged on a line plane centerline object.

[0061] (8) such as Figure 11 As shown, on the preset operation interface of the disc buckle bracket plane object, by giving the minimum spacing between adjacent disc buckle bracket plane objects and the number of disc buckle bracket plane objects, multiple disc buckle bracket plane objects can be created in batches along the centerline of the line plane.

[0062] (9) such as Figure 12As shown, by drawing a turning line ZZX formed by the joint of two line segments on the disc buckle support plane object of the outer edge, the two end points of the turning line ZZX are respectively coincided with the small dots in the disc buckle support plane object representing the disc buckle upright rod object, and the pointing of the turning protruding point of the turning line ZZX represents the extension direction of the disc buckle support plane object; thereafter, a given interval is given on the preset operation interface of the disc buckle support plane object, and a single-row disc buckle local plane layout PKPM3 as shown in Figure 13 is established.

[0063] (10) As shown in Figure 14 , a rectangular or polygonal closed line frame FBX is drawn on a disc buckle support plane object PKPM, and through the button operation on the preset operation interface, all transverse horizontal rods, longitudinal horizontal rods and disc buckle upright rods in the disc buckle support plane object within the closed line frame are deleted, and a hollow disc buckle support plane object PKPM4 as shown in Figure 15 is obtained.

[0064] (11) The disc buckle support plane object and the disc buckle upright rod object group are selected, and through the button operation on the preset operation interface, the longitudinal spacing of the disc buckle upright rod in the disc buckle support plane object is automatically modified according to the longitudinal spacing of the selected disc buckle upright rod object group, and the disc buckle support plane object after the longitudinal spacing adjustment is automatically generated.

[0065] (12) Through the button operation on the preset operation interface, a disc buckle upright rod object group expressing the transverse arrangement of the disc buckle upright rod or a disc buckle upright rod object group expressing the longitudinal spacing can be automatically generated on a disc buckle support plane object. According to the selected disc buckle support plane object and a group of disc buckle upright rod objects, the transverse spacing of the disc buckle upright rod in the selected disc buckle support plane object can be automatically modified, or the longitudinal spacing of the disc buckle upright rod in the selected disc buckle support plane object can be automatically modified. According to Figure 16 the group of disc buckle support plane objects distributed along the line route center line object XLZX shown in the (a) figure, according to the above operation mode, a disc buckle upright rod object group LGZ2 arranged in the transverse direction as shown in the (b) figure of Figure 16 can be established. Figure 16 The vertical line at the left end in the (b) figure is the mileage position line WZX.

[0066] (13) Through the button operation on the preset operation interface, a disc buckle upright rod object group LGZ1 in the transverse or longitudinal direction can be automatically generated according to the disc buckle support plane object PKPM. Through the button operation on the preset operation interface, the transverse spacing or the longitudinal spacing of the disc buckle upright rod in the disc buckle support plane object PKPM can be automatically modified according to the disc buckle upright rod object group.

[0067] (14) By button operation on the preset operation interface, a group of disc buckle vertical rod objects corresponding to all disc buckle support plane objects on the line object XLZX in the same line plane can be automatically generated, and can be automatically arranged in the graphic page according to the relative position relationship with the associated mileage position line object, so as to represent the arrangement of the disc buckle vertical rod objects after the line object in the line plane is developed.

[0068] (15) As shown in Figure 17 , a straight line FGX is drawn between two rows of disc buckle vertical rod objects arranged transversely adjacent to the disc buckle support plane object PKPM, and by button operation on the preset operation interface, the disc buckle support plane object PKPM can be divided into two disc buckle support plane objects (PKPM5, PKPM6) at the position of the straight line FGX. Conversely, a plurality of disc buckle support plane objects on the line object XLZX in the line plane can be selected and combined into one disc buckle support plane object. Figure 18

[0069] Seven, on the bridge cross-section view, by establishing disc buckle vertical rod objects, disc buckle horizontal rod objects, disc buckle inclined rod objects, bottom mold objects, large lug objects, small lug objects and foundation cross-section objects, a group of disc buckle cross-section objects can be obtained. By button operation on the preset interface, the bridge cross-section and the group of disc buckle cross-section objects are selected, and according to the disc buckle vertical rod objects, disc buckle horizontal rod objects, disc buckle inclined rod objects, small lug objects, large lug objects and attribute information of each object, a rod finite element calculation model of the disc buckle support cross-section can be automatically generated. The rod finite element calculation model is subjected to mechanical calculation, and the strength, stiffness and stability of the disc buckle support structure are evaluated according to the calculation results.

[0070] The application will be further described in detail below with reference to the accompanying drawings.

[0071] The rapid design method of the curved bridge disc buckle support of the application comprises the following steps:

[0072] Step one, establishing a bridge elevation layout, a bridge plane layout and a bridge cross-section layout.

[0073] According to the design data of the curved bridge, the bridge elevation layout as shown in Figure 1 , the bridge plane layout as shown in Figure 3 and the bridge cross-section layout as shown in Figure 2 are first established on the graphic page, and then a template system of the bridge main beam longitudinal section and cross-section is established, the template system comprising a bottom mold object, a small lug object and a large lug object. Then, a line object XLZX in the line plane is established on the bridge plane layout, and a mileage position line object WZX is established on the bridge elevation layout as the basic object for the design of the curved bridge disc buckle support. ​

[0074] Step two, establish the disc buckle support cross section object group.

[0075] In Figure 2 the bridge cross section layout shown, the foundation cross section object, disc buckle vertical rod object, disc buckle horizontal rod object, disc buckle inclined rod object, base mold object, small ridge object and large ridge object are respectively established to express the lateral arrangement of the disc buckle support. The foundation cross section object, disc buckle vertical rod object, disc buckle horizontal rod object, disc buckle inclined rod object, base mold object, small ridge object and large ridge object together constitute the disc buckle support cross section object group shown in Figure 4 .

[0076] Step three, establish the rod finite element calculation model of the disc buckle support cross section.

[0077] Select the disc buckle support cross section object group, and establish the rod finite element calculation model of the disc buckle support cross section through the button operation on the preset operation interface. Perform mechanical calculation on the established rod finite element calculation model, and perform mechanical evaluation of the strength, stiffness and stability of the disc buckle support structure according to the calculation results.

[0078] If the calculation results of the mechanical calculation on the rod finite element calculation model do not meet the mechanical requirements, adjust the spacing of the disc buckle vertical rod in the disc buckle support cross section object group, and then perform calculation again until the calculation results meet the mechanical requirements.

[0079] Step four, establish the disc buckle support plane object group.

[0080] Establish one or more disc buckle support plane objects, and input the base point mileage, base point offset distance, longitudinal spacing and transverse spacing of the disc buckle vertical rod, and the name of the associated line plane center line and other information in the preset operation interface according to the curve bridge design data, so as to arrange the established disc buckle support plane object on the associated line plane center line object.

[0081] According to the established disc buckle support plane object and the transverse spacing of the disc buckle vertical rod object in the disc buckle support cross section object group, the transverse spacing of the disc buckle vertical rod of the disc buckle support plane object can be automatically modified. Through the movement and copying of the disc buckle support plane object, or by using the attribute information and professional functions of the disc buckle support plane object, the established disc buckle support plane object can be modified and adjusted to obtain the disc buckle support plane object group shown in Figure 5 that meets the design requirements of the disc buckle support plane arrangement of the curve bridge.

[0082] Step five, establish the disc buckle support elevation object group.

[0083] By the disc buckle support planar object distributed on the line object in the line plane, the disc buckle vertical rod object group corresponding to the disc buckle support planar object is automatically generated, and the disc buckle vertical rod object group will be arranged at the corresponding position in the bridge vertical plane layout according to the relative position of the mileage position line. The established disc buckle vertical rod object group is subjected to extension or pruning operation to obtain the disc buckle vertical rod object group satisfying the design requirements. According to the disc buckle vertical rod object group, the disc buckle horizontal rod object and the disc buckle inclined rod object are established through the button operation on the preset operation interface according to the relevant technical specifications, and the disc buckle support vertical plane object group satisfying the curve bridge disc buckle support vertical plane layout requirements shown in the bridge vertical plane layout is obtained. Figure 6 The disc buckle support vertical plane object group satisfying the curve bridge disc buckle support vertical plane layout requirements shown in the bridge vertical plane layout is obtained.

[0084] Step six, details are improved.

[0085] For the bridge vertical plane layout, the bridge plane layout, the bridge cross section layout, the disc buckle support cross section object group, the disc buckle support plane object group and other local details in the disc buckle support vertical plane object group, such as inner mold, outer mold, disc buckle support and bridge pier pull, disc buckle support horizontal scissors support and other local structure details and engineering calculation of disc buckle support, the existing drawing method or the method disclosed in the same kind of invention patent of the applicant in the prior application can be used to improve and supplement.

[0086] The local detail drawing library and the parameterized detail drawing library can also be established in advance, and the local detail drawing library and the parameterized detail drawing library are subjected to local detail drawing and modification, so that the required design detail drawing of the curve bridge disc buckle support expressed by two-dimensional graphics can be quickly completed.
