Description

Protecting cover for lower sill of fire door}

The present invention combines the first and second seal covers of the retention cover on the upper portions of the first and second upper plates of the fire door lower seal, which are steppedly provided based on the gasket, but separates the first and second seal covers between the first and second seal covers. This is a fire door lower seal protection cover that allows the gasket to be exposed to the outside through the opening, so that it does not need to be removed during fire inspection and can be left on until the occupant's preliminary inspection, thereby minimizing damage to the lower seal.

In order to prevent the spread of fire and reduce damage caused by fire when a fire breaks out within a building, fire prevention zones are divided by floor, area, or purpose, and fire doors are installed in each fire prevention zone.

Fire doors must be installed compulsorily on the front doors of apartments and other apartment complexes and office buildings, and recently, the use of fire doors in single-family homes has been increasing to reduce human and material damage caused by fire.

These fire doors must secure airtightness to meet standards such as heat loss prevention, insulation performance, and condensation prevention performance for efficient energy management of buildings, as well as smoke control performance to prevent smoke penetration in the event of a fire.

For this purpose, a gasket is installed on the door frame, or frame, where the fire door is installed, in close contact with the edge of the fire door to maintain airtightness.

The general fire door construction process proceeds in the following order: lightweight wall construction → fire door frame installation → wall gypsum board finishing → floor stone and tile construction → wall finishing construction.

In this way, after completing fire door construction, a smoke control test is conducted during fire inspection, and defect repairs are performed through a preliminary inspection process for occupants.

Generally, a protective film is attached to the upper surface of the lower sill of a fire door frame to protect the surface of the lower sill. However, even if the protective film is attached, the lower frame seal may be damaged due to movement of workers or equipment, impact of heavy objects, etc. during the subsequent process after installing the fire door frame. To prevent this, a temporary safety steel plate was previously placed on the fire door frame.

However, during fire inspection, a smoke control test must be performed with the gasket installed. Accordingly, it is customary to remove the reinforcing steel plate attached to the lower frame seal and install a gasket just before the fire inspection.

In this case, the lower sill of the fire door frame is exposed to the outside without a reinforcing steel plate for approximately 15 to 45 days from the time of fire inspection to the preliminary inspection of occupants. Therefore, damage such as bending, twisting, sagging, dents, and scratches occurs in the lower seal due to movement of workers or dropping of heavy objects.

If the lower seal is damaged like this, the surrounding floor and wall finishing materials must be removed, the mortar broken, and the lower seal replaced. Therefore, there is a problem in that defect repair is very difficult and takes a lot of time and money.
