The "fire brace hardware" is a reinforcement hardware that can form horizontal structural planes as an alternative to fire braces. The floor amplification (allowable shear strength) of the horizontal structural plane is evaluated based on the size of the compartment. It is mainly used to enhance design and secure natural light by eliminating fire braces in open spaces, and can also be utilized in areas where forming horizontal structural planes is difficult, such as staircases and second-floor bathrooms. 【Features】 ■ Can be used in areas where forming horizontal structural planes is difficult ■ Evaluates the floor amplification (allowable shear strength) of the horizontal structural plane based on the size of the compartment ■ Simple installation by placing the hardware at "2 corners" or "4 corners" depending on the size of the applicable structural compartment and attaching it with dedicated screws ■ It is also possible to use fire braces and structural plywood in conjunction, as specified in the Ministry of Land, Infrastructure, Transport and Tourism Notification No. 1347 of 2001 *For more details, please refer to the PDF materials or feel free to contact us.

The "TPB" is a high-strength pipe-type independent column base hardware that is easy to install with a single anchor bolt configuration. With the use of a single anchor bolt, the positioning and fastening processes have become easier. The "TPB60 (M16)" can absorb installation errors of approximately ±10mm, while the "TPB80 (M20)" can absorb errors of approximately ±8mm. 【Features】 ■ Easy to install with a single anchor bolt configuration ■ Pipe design allows for easy processing of columns ■ Exchangeable column support parts compatible with sizes from 105mm to 300mm and flat columns ■ Achieves high strength of 60kN/80kN *For more details, please download the PDF or feel free to contact us.

"TPB" is a high-strength pipe-type independent column base hardware that achieves high strength of 60kN/80kN. By using a high-strength anchor bolt M16, it provides a tensile strength of 60kN (TPB60), and by using a deformed anchor bolt M20, it provides a tensile strength of 80kN (TPB80). Please feel free to contact us when you need assistance. 【Features】 ■ Easy to install with a single anchor bolt arrangement ■ Pipe design allows for easy processing of columns ■ Compatible with column receiving parts that can be exchanged, accommodating sizes from 105mm to 300mm and flat columns ■ Achieves high strength of 60kN/80kN *For more details, please download the PDF or feel free to contact us.

The "TPB" is a high-strength pipe-type independent column base hardware that can accommodate square columns ranging from 105mm to 300mm and flat columns as well. By changing the column support components, it can adapt to various column cross-sections. Please feel free to contact us when you need assistance. 【Features】 ■ Easy to install with a single anchor bolt arrangement ■ Simple processing of columns due to its pipe design ■ Compatible with square columns from 105mm to 300mm and flat columns through interchangeable column support components ■ Achieves high strength of 60kN/80kN *For more details, please download the PDF or feel free to contact us.

"TPB" is a high-strength pipe-type independent column base hardware used for joints of column bases that require high pull-out resistance. In conventional products like PBH, the joint with the column material had a cross-slit shape, which required the column material to be processed in a cross shape as well. However, since TPB has a pipe shape, only mortise hole processing is needed on the column material side. The orientation of TPB can be changed to match the direction of the drift pin processing, allowing for holes to be drilled without worrying about the orientation of the hardware. 【Features】 ■ Easy to install with a single anchor bolt arrangement ■ Pipe design simplifies column processing ■ Replaceable column receiving parts compatible with sizes from 105mm to 300mm and flat columns ■ Achieves high strength of 60kN/80kN *For more details, please download the PDF or feel free to contact us.
