Description

Fabricated strongroom wall panel and wall panel structure.

       The present invention can be assembled and dismantled in the construction of a large safe room to secure a space for storing and managing important document information and goods in large institutions such as financial institutions, corporations, and public offices. The present invention relates to a prefabricated safe room wall panel and wall structure that increases space utilization, reduces structural burden on buildings, and improves fire resistance.

       In general, the amount of information and goods caused by industrial development is increasing, and the use of a large safe room is becoming common to safely store and manage it.

       In Korea, however, the development and testing of safes are actively underway, while the production of safes is an intermediate location between builders and safes companies. The safety of goods is threatened because there is no standard specification for the installation standards of the room, and foreign financial institutions are presenting the standard specification for the production of safe rooms, but there is no domestic technology to satisfy this situation, and construction is being done by direct import from abroad. .

        Conventional safe room was divided and installed by partition walls on the existing building, and the security device is installed only in the door and the existing safe building using the materials such as concrete and brick was installed and operated.

       The safe compartment of the conventional general partition wall does not satisfy the protection and fire resistance performance, there is a problem that can cause the loss of goods due to outside intrusion and fire in particular, the safe compartment constructed of concrete and brick is the load of the new safe compartment Due to the increase in cracks and deformations of existing building structures, structural reinforcement is required, and large-scale demolition and construction work must be carried out following the establishment and relocation of financial institutions. There was a problem of cost, space and environmental pollution.

Therefore, the present invention has been created for the purpose of solving the conventional problems as described above to manufacture a panel structure that is easy to assemble and dismantle to improve the construction and recycling by the relocation and new construction of the safe room and the existing safe It is designed to provide a prefabricated safe room wall panel and wall structure, which is manufactured with a small cross section compared to a real wall and not only increases the space utilization but also reduces the structural burden and improves protection and fire resistance when installed in a building due to light weight of the panel.

Hereinafter, the configuration and operation thereof will be described in detail with reference to the accompanying drawings.

In the safe room wall panel,

Welding and binding the reinforcing material 40, 40 'between the front iron plate 10 and the rear iron plate 20 and the lightweight foam concrete 50 in the space between the front iron plate 10 and the rear iron plate 20 The panel P is manufactured by pouring, but is formed by protruding stepped joints 60 and 60 'at one or both ends of the panel P.

       And using the panel (P),

       In order to install the safe room wall (C) on the wall of the building structure, the reinforcing material 40, 40 'between the front iron plate 10 and the rear iron plate 20 is welded, bound and lightweight foam concrete 50 is poured. Panel P having protruding stepped joints 60 and 60 'formed at one or both ends thereof and the protruded stepped joints 60 and 60' formed at another panel P ', respectively. Adjusting the length of the wall (C) by engaging with each other and joining by welding a flat iron plate (70, 70 ') to the outer and inner joints between the combined panel (P) and the panel (P'), respectively. To form a safe wall structure.

       The thickness of the lightweight foamed concrete 50 layer that is poured into the inside of the panel P can be adjusted in three stages according to the fire resistance performance condition.

The present invention as described above is to manufacture the unit panel, the effective connection structure of the panel and the panel and the easy adjustment of the length of the wall required to improve the performance of the wall of the safe room so that it can be properly installed in a variety of fire resistance performance buildings, lightweight By adjusting the thickness of the wall, we developed a wall that satisfies the fire resistance performance level of 1 hour, 2 hours and 3 hours, which meets the standards of the Ministry of Construction and Transportation Notice No. 2000-93 (Recognition and Management Standard of Fire Resistant Structure).

As shown in FIGS. 3 and 4, the wall panel P includes a panel P on which protruding stepped joints 60 and 60 'are formed on both sides, and a panel on which protruding stepped joints 60 are formed on one side thereof. P ').

Panels P and P 'on which protruding stepped joints 60 and 60' are formed at both sides and one side of the front panel 10 and the rear panel 20 constitute a panel P or a front panel ( 10), the inner space of the panel (P) (P ') in which the rear panel 20 and the side panel 30 are installed by welding and each of the reinforcing materials 40, 40' is bound by welding. Then, light foamed concrete 60 is poured to complete each of the panels P and P '.

As described above, when constructing the safe room with the panel P (P ') formed at one side or both sides, the protruding stepped joints 60 and 60' are coupled to the required length of the safe room wall. ).

As shown in FIGS. 1 and 2, the wall C includes a panel P 'on which one side protruding stepped portion 60 is formed and a panel on which protruding stepped portions 60 and 60' are formed on both sides. In order to mutually couple P), the protruding stepped joints 60 and 60 'of each panel P (P') are engaged with each other to be coupled to the required length of the wall C, and the protruded stepped joints A flat iron plate 70, 70 'is padded on the inner side and the outer side of the panels P and P' coupled to the 60 and 60 'to form the wall C by welding.

       Panels P and P 'used in the above are made of a layer of lightweight foamed concrete 50 which is cast inside the steel plates 10, 20 and 30 according to fire resistance (1 hour, 2 hours, 3 hours). The thickness can be adjusted in three steps according to the performance.
