Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vertical shaft portal, in particular to a design and processing method of a vertical shaft portal intersecting section formwork. BACKGROUND

[0002] The vertical shaft portal intersects with the shaft, and the intersection line is a curve, so it is difficult to obtain accurate data size using traditional technical means. For the pouring formwork treatment, the usual method is to cut a corresponding length of wood board (the width is usually 150-200mm) according to the actual length of the straight section formwork to the shaft portal large formwork, and then evenly distribute the multiple wood boards along the circumferential direction of the shaft portal section to complete the assembly of the pouring formwork.

[0003] This construction process has many edges on the completed concrete surface due to the use of multiple wood boards evenly distributed along the circumferential direction, resulting in poor visual quality. When the number of shaft portals in the shaft is large, the recycling rate of the wood board is low, and the construction efficiency is affected.

[0004] Because the intersecting section of the vertical shaft and the shaft portal is a spatial curve, it is difficult to obtain the size of the intersecting section of the formwork using traditional technical means, which makes it difficult to design and process the overall assembled metal formwork.

[0005] Therefore, a design and processing method of a vertical shaft portal intersecting section formwork is proposed. SUMMARY

[0006] The purpose of the present application is to provide a design and processing method of a vertical shaft portal intersecting section formwork to solve the problems raised in the background art.

[0007] To achieve the above purpose, the present application provides the following technical scheme: a design and processing method of a vertical shaft portal intersecting section formwork, comprising the following steps:

[0008] S1, modeling the shaft and the portal using modeling software;

[0009] S2, based on the inner surface of the portal, using equidistant curved surface and curved surface thickening to obtain a three-dimensional model of the portal formwork;

[0010] S3, using sketches, working surfaces and reference datum planes to divide the overall formwork, so that the size and weight of the formwork blocks meet the requirements of on-site construction;

[0011] S4, extracting the intersecting section formwork to generate a separate part, and using the curved surface flattening function to flatten the curved surface;

[0012] S5, in the modeling software, using the flattened three-dimensional model to generate a two-dimensional drawing with the intersecting curve;

[0013] S6, exporting the engineering drawing in the modeling software to a general CAD drawing;

[0014] S7, importing the exported flattened intersecting segment template CAD drawing into a CNC cutting machine for blanking to obtain a curved surface template with an intersecting line;

[0015] S8. Use the plate rolling machine to bend it to the designed size and complete the assembly and forming of the rib plate of the template on the mold.

[0016] Preferably, in step S2, the horse head door template is completely attached to the inner wall of the horse head door.

[0017] Preferably, in step S3, the entire template is divided into six blocks.

[0018] Preferably, in step S4, a straight edge of the curved template is used as a flattening edge line to complete the flattening of the curved template.

[0019] Preferably, after flattening the curved template, a planar three-dimensional model with intersecting curve segments is obtained.

[0020] Preferably, in step S6, the CAD general drawing is exported at a ratio of 1:1.

[0021] Compared with the existing technology, the beneficial effects of the present invention are: using an integral assembled horse head door formwork with an intersecting section, a close fit between the shaft large formwork and the horse head door formwork is achieved in the intersecting section formwork, which changes the construction process of using cut wooden boards to evenly distribute the intersecting sections of the horse head door in the circumferential direction. Compared with the previous construction process, the construction of a single horse head door can save 10 hours in the vertical formwork casting and 50,000 yuan in construction costs. The finished horse head door concrete has a good visual quality. This method is more effective when a large number of vertical shaft horse head doors are constructed. DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Example

[0023] The present invention provides a technical solution: based on the shaft design drawings, the stretching, lofting and other functions of the Solidworks software are used to complete the three-dimensional modeling of the shaft and the horse head door; the surface inside the three-dimensional model horse head door is obtained by using the isometric surface, surface thickening, surface merging and other functions in the software surface module to obtain a three-dimensional model of the horse head door template that is completely fitted with the inner wall of the horse head door; according to the design section of the horse head door and combined with construction experience, the software's splitting function is used to split the entire template, and the intersecting section of the entire arch model is divided into 6 blocks for easy on-site transportation and installation; the single block three-dimensional model is used to complete the extraction of the enclosure of a piece of arch template through the software's insert new part function. The software's surface flattening function is used to select the outer surface of the surface model, and a straight edge of the surface template is used as the flattening edge to complete the flattening of the surface template, thereby obtaining a planar three-dimensional model with intersecting curves. In Solidworks, the flattened 3D model is used to directly project and generate a 2D engineering drawing of the intersecting segment template. The engineering drawing in Solidworks is exported as a general CAD drawing of the template enclosure at a 1:1 ratio. The part models of the remaining intersecting segment templates are extracted and drawn in the same way. The exported CAD drawing of the intersecting segment template is imported into a CNC cutting machine for layout and cutting to obtain an enclosure with a curved template of an intersecting line. The cut template enclosure is bent to the designed size using a plate rolling machine, and the template ribs are assembled and formed on the mold.

[0024] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
