Description

Technical Field

[0001] The invention belongs to the technical field of ship safety protection, and in particular relates to a falling-prevention triangular profile structure and an installation method. Background Art

[0002] At present, in order to control the structural weight of the ship, various ship types open waist-shaped openings in the main hull non-strong components, platforms, ribs and other areas to reduce the structural weight. This kind of opening that is used to reduce the weight of the ship without being affected by other factors is called a lightening hole. However, some positions are opened on horizontal platforms. This position is used as a passage for construction and subsequent maintenance. Usually, we arrange profiles on the lightening holes of this passage to prevent people from falling into the lightening holes. We call this profile anti-fall square steel.

[0003] The anti-fall square steels on the market are all square and are arranged along the longitudinal direction of the lightening holes during construction and laying. There are two main ways to arrange the anti-fall square steels, one is to install them perpendicular to the platform, and the other is to install them at a 45° angle to the platform. Since the anti-fall square steels are all arranged in the ballast tank and also need to have an anti-slip effect, the tank is damp for a long time and silt adheres to the platform. The actual application of the first installation method is not recognized by some owners, who believe that it is parallel to the platform and that it is also parallel to the sole when it actually contacts it, and the anti-slip effect is poor; the second method is to install it at a 45° angle. Since the square steel itself is relatively small, the welding space is small when it is installed at 45°, and the construction is difficult. However, in actual use, the contact surface with the sole is a point plane, which has a better effect.

[0004] Therefore, how to provide a fall-proof triangular profile structure and installation method that can simplify the construction process, improve operability and save construction costs has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present invention provide a fall-prevention triangular profile structure and an installation method, which can simplify the construction process, improve operability and flexibility, and save construction costs.

[0006] In one embodiment of the present invention, a fall-preventing triangular profile structure includes: a triangular cross-sectional structure formed by a first side 1, a second side 2 and a third side 3 connected in sequence; the angle α between the second side 2 and the third side 3 is 90° to 120°, and the angle β between the first side 1 and the second side 2 is 30° to 60°; the length of the third side 3 is greater than the length of the first side 1, and the bottom surface of the third side 3 is provided with an anti-slip structure.

[0007] Furthermore, the angle α is preferably 90°, the angle β is preferably 45°, and the length of the third side 3 is 1.5 to 2 times the length of the first side 1 .

[0008] Furthermore, the anti-skid structure comprises: wavy anti-skid patterns arranged at intervals along the length direction of the third side 3, the interval between adjacent anti-skid patterns is 5mm-8mm, and the pattern height is 1.5mm-2mm.

[0009] Furthermore, the profile structure is made of galvanized steel or stainless steel, and a chamfered structure is provided at each edge connection of the profile structure, and the radius of the chamfered structure is 2mm-3mm.

[0010] In another embodiment of the present invention, a method for installing a triangular profile structure for preventing a fall is provided, based on the triangular profile structure for preventing a fall as described in any one of the above items, and the method for installing comprises:

[0011] The second side 2 maintains a vertical relationship with the surface of the structural platform, the third side 3 maintains a horizontal relationship with the surface of the structural platform, and a welding fixing portion 4 is provided at the end of the second side 2 contacting the structural platform.

[0012] Furthermore, a welding plane extending 8mm to 10mm along the bottom of the second side 2 is set as a welding fixing portion, and double-sided fillet welds are used during welding, the weld leg size is not less than 4mm, and the weld length is not less than 80% of the profile side length.

[0013] The beneficial effects brought by the present invention are as follows:

[0014] It can be seen from the above scheme that the embodiment of the present invention provides a triangular profile structure and installation method for preventing falling, wherein the triangular profile structure comprises: a triangular cross-sectional structure formed by a first side 1, a second side 2 and a third side 3 connected in sequence; the angle α between the second side 2 and the third side 3 is 90° to 120°, and the angle β between the first side 1 and the second side 2 is 30° to 60°; the length of the third side 3 is greater than the length of the first side 1, and an anti-slip structure is provided on the bottom surface of the third side 3. The technical scheme of the present invention can simplify the construction process, improve the flexibility of operation, and save construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a schematic diagram of a triangular profile structure for preventing a fall according to an embodiment of the present invention;

[0016] In the figure, 1 is the first side, 2 is the second side, and 3 is the third side. DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] At present, the profile structure is installed at an angle of 45°. There is a 45° space for the installation angle. Since the square steel is small (22*22mm), the actual welding space is small and welding is difficult, and the welding quality is difficult to guarantee. In addition, since the square steel has been used in ballast tanks and humid areas for a long time, the long-term corrosion requires higher welding. However, when the upper end contacts the sole, it is a point contact, which can play a better anti-slip effect.

[0019] The profile structure is installed at a vertical angle of 90°. When installed perpendicular to the structural platform, the welding space and sight are good, which can ensure the welding quality. However, due to the long-term pumping and drainage of the ballast tank, it is inevitable that there will be corrosion such as silt and marine organisms in the tank. When people pass through, the contact between the sole and the anti-fall square steel is a surface-to-surface contact surface, and the anti-slip effect is poor.
