The problem that the structure around the window frame is prone to deformation in the segmented construction and hoisting process is effectively solved. The method comprises the following steps: determining the size of a window opening; a connecting gap bridge is arranged in the middle of the interior of the window opening, and the large-size window opening is divided into two small-size openings which are arranged side by side in the left-right direction through the connecting gap bridge. Reflecting the determined connection gap bridge into the model to complete modeling; the model is separated and converted into a numerical control cutting instruction, the numerical control cutting instruction is sent to a production department for numerical control cutting, and window trepanning construction is completed; and after the segmented construction is completed and before the window is installed, the connecting gap bridge is cut off, the free edge of the opening of the window is polished to be smooth, and the window is installed.

Description

Technical Field

[0001] This invention belongs to the field of ship structure construction technology, and in particular relates to a method for reducing the deformation of window openings in ships. Background Technology

[0002] Currently, to reduce blind spots in the bridge, the window openings in the bridge are relatively large. Taking a 210,000-ton bulk carrier as an example, the bridge window openings are either rectangular openings of 2068mm×1168mm / R134mm, parallelogram openings of 1848mm×1168mm / R134mm, or trapezoidal openings of 1491mm×1395mm×1168mm / R134mm.

[0003] Because the steel plates of the cab structure are relatively thin, generally 7mm or 10mm, the structure around the window frame is prone to deformation during the segmented construction and hoisting process, which causes the shape of the opening to be deformed and does not match the shape of the window, making it impossible to install the window properly later. Summary of the Invention

[0004] The purpose of this invention is to provide a method for reducing the deformation of window openings on ships, effectively solving the problem of easy deformation of the structure around the window frame during segmented construction and hoisting.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a method for reducing the deformation of window openings on ships, comprising the following steps: S1, determining the size of the window opening; S2, setting a connecting bridge in the middle position of the window opening, dividing a large-sized window opening into two smaller-sized openings side by side through the connecting bridge; S3, reflecting the determined connecting bridge into the model to complete the modeling; S4, after separating the model, converting it into CNC cutting instructions, sending them to the production department for CNC cutting to complete the construction of the window opening; S5, after the segmented construction is completed, before the window is installed, cutting off the connecting bridge, smoothing the free edge of the window opening, and installing the window.

[0006] Furthermore, the specifications of the connecting bridge are consistent with those of the mother plate.

[0007] Furthermore, the width of the connecting bridge is 200-300mm.

[0008] Compared with the prior art, the beneficial technical effects of the present invention are: (1) The present invention reduces the area of ​​the large opening by adding a connecting bridge in the window opening, thereby increasing the structural strength around the opening and reducing the structural deformation generated during construction.

[0009] (2) The technical solution of the present invention is simple to implement, and the construction process can be completed by CNC cutting.

[0010] (3) The connecting bridge added by the present invention is simple and convenient to cut off in the later stage, will not damage the base material, and will not affect the installation of the window. Attached Figure Description

[0013] Attached diagram labeling: Connecting bridge-1. Detailed Implementation

[0014] Example 1: A method for reducing the deformation of window openings on ships, comprising the following steps: S1, measuring the size of the window opening.

[0015] like Figure 1 As shown, the central window opening is a rectangular opening of 2068mm×1168mm / R134mm, and the two side windows openings are trapezoidal openings of 1491mm×1395mm×1168mm / R134mm. The common window frame width of the adjacent windows is 100mm, and the steel plate thickness is 7mm.

[0016] S2. A connecting bridge 1 of appropriate width is installed in the middle of the window opening. Through the connecting bridge 1, a large window opening is divided into two smaller openings side-by-side. For example... Figure 2 As shown in the shaded area, the width of the connecting bridge 1 for the largest window opening in the middle is 300mm, while the width of the connecting bridge 1 for the other window openings is 200mm. The specifications of connecting bridge 1 are the same as those of the mother plate, and the thickness is 7mm.

[0017] S3. Reflect the determined connecting bridge 1 into the model to complete the modeling.

[0018] S4. After separating the model, convert it into CNC cutting instructions and send them to the production department for CNC cutting to complete the construction of the window opening. Since the connecting bridge 1 is naturally formed after the CNC cutting of the mother plate, it does not need to be processed during the segmented construction process. The connecting bridge 1 is used as a shape-preserving reinforcement for the opening.

[0019] S5. After the segmented construction is completed, before the window is installed, cut off the connecting bridge 1, smooth the free edge of the window opening, and install the window.

[0020] This invention adds a connecting bridge 1 to the traditional window opening, dividing a large opening into two smaller openings. This reduces the opening area of ​​the base material while increasing structural strength, fundamentally reducing structural deformation during construction.

[0021] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
