Description

Penetration sleeve with lock ring for fireproof filler}

The present invention relates to a penetrating sleeve provided with fire-resistant filler that prevents the spread of fire between floors in the event of a fire in a building.

In general, buildings with a multi-story structure must form a through hole in the slab so that various pipes, such as drain pipes, can penetrate between floors. To this end, a through sleeve through which pipes can be inserted into the form for slab construction is installed. Afterwards, mortar is being poured.

The through sleeve installed in the form usually has an inner diameter larger than the outer diameter of the pipe. This is to enable the pipe to be easily inserted into the through sleeve in the future and to respond to deformations such as bending of the pipe. For this reason, a gap is created between the penetrating sleeve and the pipe, and in the event of a fire, flame or toxic gas can flow through this gap, causing the fire to spread between floors and increasing casualties.

Due to this problem, recently, a fire-resistant filler that expands due to heat in the event of a fire is provided between the penetrating sleeve and the pipe to prevent the spread of fire and minimize casualties. These fireproof fillers are generally made by injecting a separate structure inside the penetrating sleeve so that the penetrating sleeve and fireproof filler are integrated into one piece, and a method where the fireproof filler is mounted on the top or bottom of the penetrating sleeve using a separate mounting means. It is widely used.

However, the former method cannot be applied to remanufactured or already constructed penetrating sleeves, and has the disadvantage of having to manufacture separate molds for each penetrating sleeve standard.

In addition, the latter method has the advantage that the fire-resistant filler can be fixed within the through-sleeve by a mounting means, so it can be applied to a re-manufactured or already constructed through-sleeve. However, it is not easy to assemble and install the mounting means for fixing the fireproof filler, and even if installation is easy, there is a problem that it cannot be firmly fixed. The reason why the fire-resistant filler must be firmly fixed within the penetrating sleeve is because in the event of a fire, the fire-resistant filler expands in a uniform direction and must block the flame. However, if the fire-resistant filler is not firmly fixed, the fire-resistant filler shakes during expansion and does not expand uniformly, resulting in a problem in which the flame is not effectively blocked.
