Description

FIELD OF THE INVENTION [0001] The present invention relates to a method of joining sheet fabrics for speed doors,

The present invention relates to a method of joining a sheet material for a speed door, which can securely connect the sheet material and prevent the joining part from being separated in the course of winding the sheet material, And more particularly, to a method of joining a sheet material for a speed door that can prevent the sheet material.

In general, SPEED DOOR is an opening / closing door that is installed at the doorway, logistics facility (distribution center), and product entrance / exit of various manufacturer's factory, and it is a door that can be opened / closed more quickly than the existing left / . These speed doors have the effect of blocking the movement of wind and heat, maintaining the temperature and humidity, improving the efficiency of the cooling / heating energy, and being able to install in the narrow space to maximize the space efficiency. The place is on the rise.

Such a speed door is constituted by a shielding film capable of blocking the inside and the outside, a rotating rod for moving the shielding film up and down, a driving motor for driving the rotating rod, and the like. In addition, in order to minimize shaking of the shielding wind in the outside wind, steel pieces or the like may be attached to the both ends of the shielding film to increase the weight.

The barrier membrane used in the speed door is usually made of a material such as cloth or synthetic resin that can be easily rolled up on a rotary bar and is made of a material that can be natural lighted in the interior, There is an example in which a transparent barrier made of a transparent material is used in combination. In the case of a speed door including a barrier made of a combination of a plurality of barrier membranes, the material of the speed is easily shaken by a strong wind or an impact, In case of using the cut-off membrane, it often happens that when the process of drying and unwinding on the rotating rod is repeated a plurality of times, the detachment occurs in the joint portion, which often causes problems such as repairing, repairing or replacing frequently.

In the case of joining and connecting the conventional cut-off film, particularly the synthetic resin cut-off film, the ends of the two cut-off films to be connected are obliquely cut obliquely so that the cut-off portions face each other and an adhesive is applied to the cut- Pressed by using a press.

However, since the joint portion of the barrier membrane thus manufactured is formed in a straight line from a side view, there is a problem that the stressed portion, that is, the outer portion of the breakage film is frequently wiped off during the operation of rotating the rotation bar.

In order to solve the problem of deviating the joining portion, a method has been proposed in which a profile is embedded in a portion where a shielding film is joined as disclosed in Korean Patent Laid-Open No. 10-2010-0049252. However, since the method described in the above-mentioned prior art is required to manufacture and install a profile having a complicated structure, the installation cost is increased and the shielding film must be inserted into the fixing member. However, since the attaching method uses the sewing, In case of using synthetic resin, sewing can be loosened by pressure if it is used for a long time even if sewing is performed, which is a problem of poor durability.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
