Description

Sandwich panel sealing type fire diffusion prevention structure using composite type cap and its construction method

The present invention relates to a sandwich panel sealed fire spread prevention structure using a composite finish cap and a construction method therefor, and relates to an outdoor joint and an indoor joint of a sandwich panel wall structure, a sandwich panel floor, a structure with eaves of a sandwich panel roof structure, and a eaves. The present invention relates to a sandwich panel sealing type fire spread prevention structure using a composite closing cap that closes the connection and ends between sandwich panels by using a closing cap in a structure without a sandwich panel to seal the insulation in the sandwich panel, and a construction method therefor.

Sandwich panels have been widely used in various facilities (factories, warehouses, commercial facilities, houses, etc.) since the 1970s. Such a sandwich panel had the advantages of excellent economic feasibility (low average unit price), excellent thermal insulation and construction convenience, reproducibility, and excellent adhesion to concrete.

However, in spite of the above advantages, the sandwich panel has a fatal disadvantage, which is the fire vulnerability. That is, there was a problem that the ignition risk was large and the panel joint was weak.

In more detail, if a flame is introduced into a gap that is inevitably generated during the bonding of sandwich panels, the core material of the sandwich panel is a combustible material. The fire hazard is very high in the case of a compartment fire because it reaches the flash over, which is the peak stage of the fire, in a very short time.

In addition, if the molten core material flows out of the panel or if a flame is ejected through a crack, the fire may spread to adjacent buildings.

In addition, radiant heat in the room and the heat generated by the vaporization of the core material inside the insulation is conducted to the steel plate and causes deformation of the steel plate.

* Inability to digest

Since the panel (iron plate) covers both sides of the insulating material, the water poured into the sandwich panel does not penetrate into the sandwich panel during fire suppression work such as sprinkler facilities or fire brigade, making it difficult to extinguish the fire. Not only does it get caught, but it also burns for a long time even after firefighting.

* Risk of casualties

The use of organic insulation materials such as EPS and urethane foam and the adhesive used to bond the steel plate and the insulation material generate gases and a large amount of smoke that are harmful to the human body in case of fire. The generated smoke and toxic gas make it difficult to secure a visible distance and cause behavioral disorders such as difficulty breathing, work force, and loss of cognitive ability. act as a factor

The present invention has been devised to solve the above problems, and an object of the present invention is to solve three causes of a sandwich panel's weakness to fire.

In order to solve the first cause, combustible polystyrene foam, a semi-non-combustible board that meets Article 24 of the Quality Recognition and Management Standard for Building Materials, etc. was used. By using finishing caps of different shapes for the outdoor and indoor joints of the sandwich panel wall structure, the floor of the sandwich panel, and the structure with and without eaves of the sandwich panel roof structure, the connection and ends of the sandwich panel are closed. By creating an airtight sealed fire spread prevention structure, it prevents the heat of fire from propagating to the insulation as much as possible, melts the insulation within the enclosed structure to reduce the melting of the core material, and secures the barrier properties of gaps or gaps in the joints to ensure the barrier properties of ceilings and walls. By blocking the flame propagation caused by the high heat and flames of

The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the following description.

In addition, it is possible to satisfy the quality required in the quality certification test (fire prevention and fire prevention performance), and at the same time, it is possible to improve the fire diffusion prevention performance and fire prevention performance. In other words, it was confirmed that the sealing degree of the sandwich panel was increased when combined using the devised composite finishing cap, which not only blocks the airflow inside and outside the sandwich panel, but also improves the fire protection performance of spreading the flame to adjacent structures. In addition, by using the F-bar as a bonding material, the bonding strength between the panels is improved, minimizing the deformation of the steel plate due to heat, and the F-bar firmly fixes the sandwich panel to the floor, thereby strengthening the structural and supporting power.

In addition, ease of construction and accuracy (exclusion of unnecessary processes) can be achieved. By using F-bars on the floor and ceiling, a work baseline is installed, and the continuity of the work order (like matching Lego blocks) is established and can be easily assembled, eliminating unnecessary processes. Not only can it be excluded, but also the construction quality and productivity can be dramatically improved.

As a result, this construction method not only satisfies the quality and performance required in the quality certification test (fire prevention performance and fire protection performance), but also required manpower (reduction of input manpower and simple training of non-experts) to build proficiency. Completed) and material costs are also reduced, so overall cost savings can be expected.

The joint between the joints can be completely sealed, so that the joint of the subsidiary materials is integrated, thereby preventing direct exposure to the flame from the inside and the outside in the edge part and the joint part between the panels, which are vulnerable to fire, and the upper steel plate 110 and Since the lower steel plate 130 and the F-type finishing caps 200 and 200' are in contact with each other and bonded to each other, it delays the combustion of the insulator 120 by double blocking the fire heat transmitted directly to the outer edge of the insulator 120. By minimizing melting as well as blocking the flow of the molten insulating material to the outside, it can function more effectively as a fire spread prevention wall structure.

In addition, since it is possible to form an indoor wall sandwich panel structure with superior sealing properties compared to the conventional method using only one ㅛ-shaped closing cap 300 integrally formed, the workability can also be remarkably improved.
