製品案内 キーラム耐震開口フレーム

In the case of home construction, it has become increasingly common for clients to request multiple/large windows to be placed on the southern wall or to designate the first floor as parking space due to ownership of multiple motor vehicles and for efficient property use.

 

In such cases, until recently, the size, placements and the likes were restricted in the strength of the building. Solutions to structural strength, however, can be found with the use of the earthquake-proof frame by Keylam, allowing for the actualization of any building plan.

The differences in strength of one die with reinforced opening and the other die without any reinforcing is clear. Furthermore, when the openings become concentrated to a side wall, the building will be in danger of twisting during earthquakes.

 
 

Characteristics and Valuable Points

The earthquake-proof frames by Keylam have prepared two types of products; BOX type (mainly for 1st floor) for windows and their likes, and also the GATE type (strictly for ground floor) for parking space and entrances. By simply installing the earthquake proof frames by Keylam (using lag-screw bolts as shown in the figure) into frames built through common construction (Japanese post and beam construction) practices, the openings can now be treated equally as a structural wall (used by brace or structural plywood) . 

The earthquake-proof frames Keylam do not require complicated structural calculation or special technical skills, because the frames are calculated as a brace or structural plywood.

※As the frame uses Keylam Material, flexibility is given in the dimension and virtually any size is possible.

Secret to the Strength

The strength in the Keylam earthquake-proof frame is designed to withstand the horizontal load (earthquake, wind).

When the moment diagram in the frame is diagnosed, we can observe that the corners of the frame receive the most stress.

 
BOX Type:Aramid Adhesion   GATE Type:Aramid + Bolt

Joint Adhesion

The green section of the frame is the aramid fiber and adhesive. The tensile strength of aramid fiber is five times that of steel. Therefore, the green section of the frame resists the horizontal load, caused by earthquakes and hurricanes.
