Description

[0001] The present invention relates to a panel fastener for a large refrigerator,

The present invention relates to a panel-fixing hook for a large-sized refrigerator, and more particularly, to a panel-fixing hook for a large-sized refrigerator, in which a ceiling panel fixture is detachably coupled to a hook used for connecting a panel for a large refrigerator, And a ceiling panel fixing member coupled to one side of the hook is connected to an anchor bolt or beam fixed to the ceiling with a bolt or wire or the like, The panels can be more firmly fixed to the ceiling of the building through the ceiling panel fastener detachably coupled to the hooks.

Generally, a ceiling panel of a prefabricated building or a prefabricated large refrigerator is assembled by attaching a small plate to an angle fixed on a ceiling fixing neck, or fixing a large plate by screw assembly or a nail.

However, the ceiling panel having such a shape is constituted by a thin plate, and there is a disadvantage that the effect of sound insulation and heat insulation can not be obtained, and there is a closed end to which a separate heat insulating material is layered.

Therefore, in recent years, resin plates made of soundproofing and heat insulating materials have been assembled and used. However, as means for fixing them to the ceiling, a method using a fixed angle or the like is used as described above.

The above method has a drawback in that the work efficiency is lowered because there is a closed end which requires a double operation such as a separate angle installation and a fixing operation to the angle.

In recent years, the demand for prefabricated structures connecting panels has been increasing due to advantages of simplicity of assembly and quickness of construction, and it is very important that the panel and the panel are tightly and firmly connected to each other in the prefabricated structure. When a gap is formed between the panels, the inside and the outside are not completely blocked so that the inside of the panel gets wet. Especially, in case of a low-temperature warehouse, cold air inside the panel is counted to the outside, Because.

In order to solve such a problem, a hook is used between the panel and the panel so as to closely contact each other in the connection process.

As shown in FIG. 1, the conventional panel-type panel connecting hook is formed by a hexagonal wrench that is provided in a side panel 1 and is detachably coupled to a shaft having a hexagonal wrench hole 412a, A first hook (2) provided with a cam locker (4) provided with a hook (42) rotated by the hook (42); And a second hook 3 which is recessed in the other panel 1 and has a hooking pin 31 for hooking the hook 42 of the first hook.

However, the conventional prefabricated panel connecting hook having the above-described configuration is formed of hard synthetic resin mainly in consideration of convenience of manufacture and manufacturing cost, and is highly resistant to deformation and breakage when external impact such as temperature change, vibration or typhoon is applied, In this case, the inside / outside airtightness of the panel is not maintained and, in severe cases, it may cause the collapse of the prefabricated structure.

As a conventional technique for solving such a problem, Korean Utility Model Registration No. 20-0337831 discloses a configuration in which a metallic reinforcing material is insert-injected in the process of manufacturing a hook.

However, there is a problem that the hook main body can not have sufficient strength only by inserting the metal-made reinforcing member into the hook.

Meanwhile, the hooks for connecting the conventional ceiling panels and the ceiling panel fasteners for fixing the ceiling panel to the ceiling surfaces are separately manufactured as described above, and they are installed between the ceiling panels according to their respective purposes In particular, since the hook and the ceiling panel fastener need to be installed at different positions, there is a problem that the assembling time and cost are unnecessarily increased.
