Description

Screen-type heat insulating and blocking shutter {Fire and smoke proof screen shutter}

The present invention relates to a screen-type heat shield and shutter, and in particular, the first and second screens are arranged to be spaced apart from each other in front and behind the support frame, and are arranged to be wound by an opening and closing means, so that they can also serve as both a heat shield and a heat shield. In addition, the screen has an improved structure so that the connection parts that connect the screen cuts to each other are firmly connected, the connection work of the screen cuts can be easily performed, and it can provide sufficient stability against wind pressure generated in the event of a fire. It relates to type heat insulation and barrier shutters.

In general, buildings are equipped with various fire-resistant structures such as fire shutters, fire doors, and fire walls to prevent fires from spreading throughout the interior of the building in the event of a fire.

In the case of these fireproof structures, most of the representative building materials currently widely used in Korea are made of steel plates.

However, these products can block flames and toxic gases as they are made of steel plates, but they lack heat insulation performance, are difficult to process, and are limited in their appearance as various types of finishes are not possible.

Accordingly, due to various changes in the composition of the material, it does not meet the necessary and sufficient conditions for various types of architectural finishing and interior materials, and is therefore currently used as a material with only fragmentary characteristics, with its use limited.

Meanwhile, fire shutters prevent outsiders from entering a specific space and at the same time block harmful factors such as flames, smoke, and toxic gases in advance to prevent them from spreading from the point of ignition.

In addition, it is equipped with emergency escape doors that can be used only to quickly and safely evacuate people from a fire space or fire prevention space.

Current building and fire laws regulate the use of non-combustible, semi-non-combustible, and flame-retardant materials for finishing and interior materials used inside buildings.

In addition, to prevent the spread of fire and protect people, buildings over a certain size must be fire-proofed, and fire walls, fire doors, or fire shutters must be installed to block fire areas, and materials that can withstand an appropriate amount of time must be used. there is.

This is to prevent the spread of flames in preparation for fire and ensure the safety of life and property from toxic gases generated during combustion.

Currently, various types of architectural finishing and interior materials with non-combustible, semi-non-combustible, and flame-retardant properties are being developed, but there are very few products with excellent performance.

However, these conventional fire-resistant structures are not able to smoothly block the high heat generated by the fire, and as a result, the high heat spreads to the area adjacent to the fire, which not only makes it difficult to re-enter for fire suppression, but also causes the high heat to spread. There was a high risk that a fire could spread along the conduction road and cause casualties.

In order to solve the problems of the prior art, looking at the fire prevention screen shutter, Republic of Korea Patent No. 10-1438052 (registered 20140829), it includes a support frame installed at the lower part of the ceiling of the building, a guide frame installed on both sides of the lower part of the support frame, and We propose a configuration that includes a screen shutter that is inserted into a guide frame and moves in the floor direction, and the support frame includes a rail support formed to support or move the screen shutter and a guide rail that presses both sides of the guide frame in the left and right directions. I'm doing it.

However, this prior art has the disadvantage that the uncut screen must be equipped with a support frame and a guide frame to withstand wind pressure, making the work complicated and taking a long time.

In addition, the screen can only withstand wind pressure if it is coupled to the rail support and guide frame that form the support frame, and even if the screen partially needs repair or replacement, there is a problem of cost in having to replace the screen as a whole.

Related prior art is a device with an insertion groove formed at the top, as disclosed in Korean Patent Publication No. 10-1722921, "Lightweight partition structure for fire escape with fire screen shutter" (registration date: 2017.03.29) 1 panel, a first horizontal runner having a groove formed in which the lower end of the first panel is seated inward, a second panel having an insertion groove formed in the lower end, and a second horizontal runner having a groove formed in which the upper end of the second panel is inserted inward A runner, a third panel located between the first panel and the second panel and having an insertion groove formed at one end, and a third panel located between the first horizontal runner and the second horizontal runner, the first panel and the second panel and a first vertical runner having a groove inserted into one side of the third panel, a fourth panel positioned between the first panel and the second panel and having an insertion groove formed at one end of the third panel, and a first horizontal runner, and A second vertical runner located between the second horizontal runners and having a groove formed in a groove into which one side of the first panel, the second panel, and the fourth panel is inserted inward, an insertion groove formed at the top of the first panel, and a second A first partition, a second partition, and a first partition having a center panel formed on the edge of an insertion groove formed at the bottom of the panel and a coupling protrusion each inserted into an insertion groove formed on one side of the third panel and the fourth panel. and a rotating shaft on which the screen is wound around the outer diameter, a drive motor that rotates the rotating shaft forward and backward, a switch that controls the drive motor, and a device installed on both ends of the screen to guide the raising and lowering of the screen. It includes a shutter equipped with a guide rail.

However, in the case of existing screen-type fire shutters, the screen cut portion is made of fire-resistant material and the edges on both sides are supported by a support frame to be able to lift and lower, but the combined structure of the screen and support frame prevents small shocks transmitted from the outside. Since it has a structure that is easily torn or separated, it has the disadvantage of losing its fire protection function as the screen cut portion separates from the support frame due to wind pressure generated in the event of a fire.

For this purpose, other prior technologies that have been improved include, as disclosed in Korean Patent Publication No. 10-2222182 "Frame for screen-type heat-insulating fire shutters" (registration date: 2021.02.24), heat-insulating screens for fire shutters of a desired length. A screen type in which a frame formed of a clip part and a square pillar that each accommodate the cut part are arranged as a pair facing each other in the up and down directions, and a reinforcement part in which the clip part is combined on both sides of the frame and a connection part that connects the reinforcement parts to each other. This relates to a frame for a heat-insulating fire shutter.

However, each cut part is connected by a connection part that connects the reinforcement part to which the existing clip part is combined, but the connection work is complicated and the weight of the connection part is insufficient, which reduces the sense of stability against wind pressure generated in the event of a fire. In addition, existing screen-type fire shutters in particular have the disadvantage of not sufficiently satisfying the heat insulation function and not having a blocking function.

Korean Patent Publication No. 10-1722921 “Lightweight partition structure for fire evacuation with fire screen shutter” (Registration date: 2017.03.29) Korean Patent Publication No. 10-2222182 “Frame for screen-type heat-insulating fire shutter” (Registration date: 2021.02.24)
