Description

Technical Field

[0001] The utility model belongs to the technical field of ships and ocean engineering, and particularly relates to a fixing device for marine gratings. Background Art

[0002] Marine gratings have the characteristics of good ventilation effect and strong load-bearing capacity. They are an important part of the safety passages in ships and ocean engineering and are widely used on decks and various platforms of chimneys. At present, marine gratings usually adopt a fixing structure of screws and nuts to connect with grating supports. During installation, first, drill holes in the grating supports, weld nuts on the grating supports according to the positions of the holes, then place the gratings and fixing clips, and pass the screws through the central round holes of the fixing clips and the nuts and tighten them, so as to fix the marine gratings on the grating supports.

[0003] When adopting the fixing structure of screws and nuts for marine gratings, due to the installation process of nut thermo-welding operation, the paint on the front and back sides of the original grating supports will be damaged. Since the height of each structural platform layer inside the ship exceeds 3m, corresponding high-altitude operations such as grinding and painting will be increased, increasing the operation tasks and reducing the construction efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a fixing device for marine gratings.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fixing device for marine gratings includes gratings and grating supports;

[0007] A plurality of connection holes are formed in the grating supports, and the connection holes are located between adjacent grating plates of the gratings;

[0008] Riveting nuts are adaptively installed in the connection holes;

[0009] Fixing clips are arranged on the upper parts of the riveting nuts, and the mounting holes on the fixing clips are vertically aligned with the middle threaded holes of the riveting nuts;

[0010] Screws are adaptively installed in the vertically aligned mounting holes and middle threaded holes.

[0011] Preferably, the riveting nut is a lantern-shaped riveting nut.

[0012] Preferably, the screw is an internal hexagon socket head cap screw.

[0013] The beneficial effects of the utility model are:

[0014] The fixing device for marine gratings of the present utility model is simple and reliable, and the installation method is simple. It does not require hot work operations such as welding and grinding. All construction processes can be completed above the grating support, improving the safety and convenience of on-site construction, shortening the construction time, and thus improving the on-site construction efficiency.
