The existing steel grating fixing hook 800 is J-shaped, and only one end of the hook fastener 100 is fixed by a fastener and a stopper, so that the fixing hook is easy to deform and lose efficacy under the impact of strong wind and surge, so that the steel grating 600 is unhooked, and the steel grating 600 is impacted. And the utility model discloses a hook firmware 100 is the U-shaped, and both ends all are provided with the fastener, keep off the piece and fix, hook firmware 100 non-deformable, and the stress point of fixed hook has increased, forms closed loop stress structure, and is whole more firm, difficult not hard up unhook. It should be understood that the first fastening member 200 and the second fastening member 400 may be identical or different; the connection manner of the first stopper 300 and the hook member 100 may be the same as or different from the connection manner of the second stopper 500 and the hook member 100.

Referring to fig. 3 to 5, in some embodiments of the present invention, the first stopper 300 is screwed to one end of the hook member 100.

The threaded connection mode is easy to disassemble and assemble; and the fastening degree of the hook 100 and the beam 700 can be conveniently adjusted, and the hook 100 can be closer to the beam 700 by screwing the first stopper 300, so that the steel grating 600 is tightly fixed on the beam 700, and the steel grating 600 is not easy to loosen. It should be understood that the stopper in the drawings is only a schematic structure, and in practice, the stopper may be a hexagonal nut, so that it has a hexagonal prism shape.

Referring to fig. 3 to 5, in some embodiments of the present invention, the second stopper 500 is threadedly coupled to the other end of the hooking member 100.

The threaded connection mode is easy to disassemble and assemble; the fastening degree of the hook member 100 and the beam 700 can be adjusted conveniently, and the hook member 100 can be closer to the beam 700 by screwing the second stopper 500, so that the steel grating 600 is fixed on the beam 700 tightly, and the steel grating 600 is not easy to loosen.

Referring to fig. 3 to 5, in some embodiments of the present invention, the first stopper 300 is welded to one end of the hook member 100.

The screw connection is easy to loosen under repeated impact, so that the first stopper 300 can be welded to one end of the hook fastener 100, the fixing of the fixing hook is firmer, and the fixing hook is suitable for severe marine environments.

Referring to fig. 3 to 5, in some embodiments of the present invention, the second stopper 500 is welded to the other end of the hooking member 100.

Threaded connection's mode, it is easy not hard up under the impact of relapse, the event can be with the one end welding of second baffle 500 and hook firmware 100 for the fixed ground of fixed hook is more firm, is applicable to abominable marine environment.

It should be understood that the connection manner of the two ends of the hook member 100 and the stoppers may be the same or different, for example, the first stopper 300 and the hook member 100 are screwed, and the second stopper 500 and the hook member 100 are welded, so that the steel grating 600 can be tightly fixed to the beam 700 by screwing and then welded to prevent the steel grating from loosening due to repeated impact.

Referring to fig. 1 to 5, in some embodiments of the present invention, the first fastening member 200 includes a first middle connecting plate 210, a first left fastening plate 220 and a first right fastening plate 230, the first left fastening plate 220 is vertically connected below the left side of the first middle connecting plate 210 (i.e., the first middle connecting plate 210 is approximately horizontally horizontal, the first left fastening plate 220 is approximately vertical to the first middle connecting plate 210), the first right fastening plate 230 is vertically connected below the right side of the first middle connecting plate 210, and one end of the hook 100 penetrates through the first middle connecting plate 210.

The conventional fastener shape is designed to be a sunken structure in order to prevent too high obstacles on the steel grating 600, but the structure strength of the fastener is reduced due to the design, so that the fastener is easily deformed or even damaged under the impact of strong wind and surge. And the utility model discloses a fastener buckles less, and structural strength is higher, can be applicable to abominable marine environment more. It will be appreciated that the center gusset is generally parallel to the horizontal plane, and the left and right gusset panels are generally perpendicular to the horizontal plane. It should be understood that the utility model discloses a fastener and traditional fastener can mixed use, on the main route of marcing of people, can adopt the fixed steel grating 600 of traditional fastener, and in other regions, adopt the utility model discloses a fixed steel grating 600 of fastener for even steel grating 600 suffers strong wind, surge and strikes, also only has partial fastener to become invalid, and steel grating 600 still can be fixed on roof beam 700.

Referring to fig. 1-5, in some embodiments of the invention, the thickness H of the first middle gusset plate 210, the first left gusset plate 220, and the first right gusset plate 230 is not less than 5mm.

In the traditional fastener shape, in order to prevent a steel grating 600 from having too high obstacles, the thicknesses of the middle connecting plate, the left fastening plate and the right fastening plate are thinner, so the structural strength is lower, and the steel grating is easy to deform and damage; and the utility model discloses a fastener has thickened the thickness of fastener specially to increased the structural strength of fastener, makeed fastener non-deformable, damaged.

Referring to fig. 1 to 5, in some embodiments of the present invention, the length L of the first intermediate connecting plate 210 is not less than 40mm.

With reference to the above, the length of the first intermediate gusset 210 is increased, thereby increasing the structural strength of the fastener, likewise. It should be understood that the length of the first interconnector plate 210 is from one end of the hook member 100 to the other end of the hook member 100. It should be understood that the width of the first middle connecting plate 210 (i.e. the distance between the first left fastening plate 220 and the first right fastening plate 230) is fixed and cannot be changed freely, and is approximately the multiple of the distance between the steel grating 600 grids 610 (plus the thickness of the two steel grating 600 grids 610, the thickness of the first left fastening plate 220 and the thickness of the first right fastening plate 230). Similarly, the width parameter of the hook member 100 is also fixed, and needs to be determined according to the width of the beam 700 to ensure that the beam 700 can be hooked.

Referring to fig. 3 to 5, in some embodiments of the present invention, the side of the first left buckle plate 220 is provided with an avoiding notch, and the avoiding notch is used for avoiding the connecting rod 620 of the steel grating 600.

Because the fastener has carried out the extension thickening, so when actual installation, the fastener has probably been hindered by steel grating 600's connecting rod 620, so can be provided with at the side of buckle and dodge the breach, dodge steel grating 600's connecting rod 620. The same applies to the first right gusset plate 230.

Referring to fig. 3 to 5, in some embodiments of the present invention, the second fastener 400 includes a second middle connecting plate, a second left fastening plate and a second right fastening plate, the second left fastening plate is vertically connected below the left side of the second middle connecting plate, the second right fastening plate is vertically connected below the right side of the second middle connecting plate, and the other end of the hook member 100 penetrates through the second middle connecting plate.

The specific composition, shape and connection of the second fastening member 400 can be found in the first fastening member 200 described above.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
