Description

Overhead shutter slab {Overhead shutter slab}

The present invention relates to a shutter plate of an overhead shutter used in a fire station, etc., while allowing the perspective of the shutter plate, which is formed to be horizontally long, also provides reinforcement against torsion while maintaining reinforcement due to bending, as well as providing excellent design. It is to.

As the shutter plate of the overhead shutter, the shutter plate is usually made of FRP in consideration of low weight, visibility and heat deformation. The length of the shutter plate is about 5-6m. The length of 10m will also exist.

However, in this case, the configuration of the shutter plate 100 has a certain thickness and the reinforcing plate member 130 having a constant thickness and width therebetween in a state in which the plate members 110 and 120 are spaced at regular intervals in order to allow perspective. Is formed in multiple layers while maintaining a constant interval, even when the length of the shutter plate 100 is long, the reinforcement for bending is made by the reinforcing plate member 130 formed in multiple layers.

In addition, by the spaced interval of the reinforcing plate 130 is to enter the light from the outside to the inside or outside to maintain the brightness during the day, even when not using the lamp, the possibility of seeing from the inside or outside To be excellent.

However, the disadvantage of such a shutter plate is that the parking space of the fire truck is kept narrow, causing a lot of problems due to the malfunction occurring when the fire truck enters or exits the shutter.

That is, the rectangular shutter plate is excellent in flexural strength, but there is a problem that the overload of the motor does not occur or the shutter plate is not fully opened and closed when the shutter is opened and closed with deformation due to torsion.

Therefore, the opening and closing of the shutter plate can not be confirmed inside the fire truck. This means that when a high-traffic fire truck enters and exits while the shutter plate is not fully opened and closed, the fire truck comes into contact with the shutter plate and is damaged. .

Accordingly, by thickening the shutter plate, a large parking space can be secured by preventing twisting. In this case, many difficulties exist for driving the entire shutter due to the overweight of the shutter plate.

Therefore, in the present invention, even when the shutter plate is formed long, it prevents warpage and prevents twisting, while maintaining a low weight even when the shutter plate is large.

To this end, by making the reinforcing plate has a constant amplitude, it is possible to prevent warpage, as well as torsion and low weight.

Therefore, the present invention maintains low weight while preventing bending strength and torsion of the shutter plate due to the amplitude of the reinforcing plate material, thereby facilitating opening and closing operation of the shutter and preventing damage to the shutter plate due to malfunction of opening and closing or damage due to overload of the motor. This will reduce the cost of maintenance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described with reference to the accompanying drawings.

As shown in FIG. 1, the shutter plate 10 of the present invention is manufactured to a predetermined length according to use, and the flat plate 11 having a predetermined thickness is formed to be symmetrically spaced apart from the front and rear surfaces, and formed to be spaced apart from each other. The reinforcing plate member 20 having a constant amplitude 21 between the plate members 11 is formed in multiple layers at regular intervals.

The shutter plate 10 is made of FRP (glass fiber reinforced plastic) material which has a slight weight and is transparent to some extent, and prevents deformation due to thermal deformation.

That is, this FRP material combines aromatic nylon fibers such as glass fiber, carbon fiber and kevlar with thermosetting resin such as unsaturated polyester and epoxy resin, which is stronger than iron, lighter than aluminum, and easy to process without rust. The shutter plate 10 is used a lot.

At this time, the plate member 11 is formed to be transparent and the reinforcing plate member 20 formed between the plate member 11 is formed in a wave shape having a constant amplitude 21 to form a wave shape reinforcement plate 20 By illuminating, it is possible to prevent the warpage and the twist of the shutter plate 10 as well as to provide various external designs of the shutter plate 10 at the same time, so that the aesthetics of the installation place can be seen.

In addition, by narrowing the amplitude 21 of the reinforcing plate 20 formed between the plate member 11 to use only one reinforcing plate 20, it is possible to prevent the same bending and to prevent distortion while providing a variety of designs. In addition, manufacturing costs will be reduced.

At this time, since the reinforcing plate member 20 is difficult to be molded in the curved state with the amplitude 21, the forming frame 30 in which the bending grooves 31 are formed at regular intervals in the longitudinal side for forming the reinforcing plate member 20 is formed. B) reinforcement plate 20 made of FRP material is forcibly inserted into the bent groove 31 formed in the forming mold 30 by pressing to be curved reinforcement plate 20 having an amplitude 21 It is possible to manufacture.

That is, the reinforcing plate member 20 is inserted into the bent groove 31 formed in the molding die 30 in accordance with the bending groove 31 so that the reinforcing plate member 20 has a constant amplitude (21). It will be possible to manufacture.

4 illustrates a manufacturing process step of manufacturing the shutter plate 10. The manufacturing process steps are as follows.

In the first step, the reinforcing plate material 20 of the plate body made of FRP material is formed in the bending groove 31 of the forming mold 30 in the forming mold 30 in which the bending groove 31 is formed at a predetermined interval so that an amplitude is formed at the length side. To insert it.

At this time, the reinforcing plate member 20 made of a plate body is relatively longer than the thickness width of the forming mold 30 so that the reinforcing plate member 20 finely protrudes to both sides of the forming frame 30 so that the adhesive part 22 is formed. It is.

In the second step, the adhesive is applied to one side adhesive part 22 of the reinforcing plate member 20 formed to be inserted into the bent groove 31 formed in the forming mold 30 to be fine on both sides, and then the plate member 11 is attached. It is adhesive.

In addition, in step 3, the flat mold member 11 attached to one adhesive part 22 of the reinforcing plate member 20 inserted into the mold mold 30 is moved in reverse to separate the mold mold 30.

In the final step, the shutter plate 10 is completed by applying the adhesive to the other adhesive part 22 of the reinforcing plate material 20 and then attaching the flat material material 11.

Therefore, the reinforcing plate 20 made of a flat plate can be manufactured in a curved shape to have an amplitude 21.

Therefore, by forming the reinforcing plate 20 having the amplitude 21 between the two flat plate 11 to prevent the bending strength and torsion of the shutter plate 10, the wave shape having such an amplitude (21) The curved reinforcement plate 20 is to be reflected on the flat material 11 of the transparent material will also provide a variety of design.
