Description

[Detailed explanation of the invention] This invention is suitable for large-scale buildings, with ease of construction, fire prevention,
For example, the present invention relates to semi-incombustible materials and large fireproof panels suitable for exterior walls that require a fireproof structure.

Conventionally, various materials such as mortar walls, bricks, and panels have been used to construct walls. However, when constructing a wall using panels, there are some weaknesses, such as narrow panel width, weak connection structure, poor insulation and waterproof properties, and exposed fixture heads on the wall. Ta. Furthermore, large-scale buildings require the use of large panels made of noncombustible materials due to fire prevention regulations, which have the disadvantage of being heavy and lacking in construction and insulation properties.

In order to eliminate these drawbacks, the present invention uses a hatch-shaped cross section of the panel to separate the decorative surface and the fixing part, and instead of using the conventional male and female engagement structure, it is possible to securely In addition to fixing the fixed part to the building foundation with bolts or nails, the joints formed by the panels are covered with a cover, and on top of that, the panel is formed into a wide and large panel, which is lighter than before, and has better insulation properties. To provide a large fireproof panel that is easy to construct and has considerable fireproofing properties.

Panel A has a plug-in structure on the left and right side surfaces of panel A, and a deformed fireproof base material 8 is attached to one side. Figure m shows panel A with a trapezoidal form 9, and figure n shows pearlite grains on the form 9. Panel A is a panel A in which one type of fire retardant 12 such as whitebait balloons, borax, and sodium metaborate is distributed, and the panel A in which one type of inorganic fiber 13 in addition to the fire retardant 12 is distributed on a foam 9 is shown in FIG.

As mentioned above, according to the panel according to the present invention,
The cross section is shaped like a hat, and the fixing part is not visible on the exterior of the wall, making it easy to fix, so the panel can be wide and securely fixed to the base. In addition, the panels are easy to install, as the sides of the panels are pressed together and the fixed parts are fixed to the base using nails or the like. Furthermore, since a fireproof base material is interposed and fixed to the joint between the panels as a noncombustible isolating material and heat insulating material between the front surface material and the back surface material, the joint has a characteristic of being highly fireproof. In addition, because a foamable inorganic layer is interposed between the surface material and the foam, it has the characteristic of being a quasi-noncombustible material and a fireproof structure. Furthermore, when a wall is formed using the panels, the joint and the head of the fixture are covered with a cover attached to the joint by elastic deformation, so that a wall with a beautiful appearance can be formed.
