TM Truss
Reliable structural system backed by extensive experience.
High-quality, high-precision structures are realized through a fully systematized management system from design, production, to construction. Compact packaging allows for easy delivery even to narrow lots, and short-term construction is possible without the use of large, heavy machinery. The high earthquake resistance has also been proven, with zero damage from collapse caused by the two earthquakes of the Great East Japan Earthquake and Tsunami, enabling the creation of highly safe facilities.

Features
Extensive track record
TM trusses are used in various locations throughout Japan.
TM trusses are used in more than 1,000 gymnasiums, large spaces, and in every other situation where people come and go. Our extensive track record is proof of our reliability.
Lightweight structure
It is also safe during earthquakes.
TM trusses can form a roof structure with about half the weight of ordinary steel frames, which reduces the load on columns and other parts of the structure and increases seismic safety. Even in the Great East Japan Earthquake of March 11, 2011, there was no damage from collapse due to earthquake. TM trusses also protect the safety of users in areas where there is a lot of human traffic, such as aisles and canopies.
Free design
We can create a form (structure) that matches the image of the facility.
The TM truss consists of a series of pipes and globes. The length and angle of the members can be set arbitrarily, enabling structural design in accordance with facility plans.
Pillarless space
Fewer columns are needed.
The TM truss structure, which is based on rational stress relationships, can provide a roof structure with a small number of columns even in large spans. This minimizes the number of columns that tend to interfere with passageways, creating a light and open space.
Flexible construction
Construction plans can be made in accordance with the property.
The systematized construction method allows for easy transportation, assembly, and management, resulting in high workability and shortened construction time. The components are lightweight single materials, which can be carried in even to sites with narrow roads, and can be worked by hand, minimizing the use of heavy machinery.
Earthquake-resistant
The seismic energy of an earthquake is proportional to the weight of the building.
The weight of the roof structure formed by TM trusses is about half that of a standard steel frame. This reduces the burden on columns and other parts of the structure and increases seismic safety. It is especially suitable for corridors and canopies where there is a lot of pedestrian traffic and safety is a major concern.
Structural beauty enhanced by lighting
Lighting enhances the beauty of the structure and makes it float beautifully in the night space.
Stenless trusses, in particular, shine more spectacularly. It can also be used not only as a roof, but also as an elegant lighting and art object.
Main construction and installation procedures
All-around construction
Pipes, globes, and other components are placed on scaffolds and hand-assembled. This is the most orthodox construction method.
Prefabricated construction
The glove and several pipes are assembled in advance in the yard into an “octopus leg” and then weighed and joined together by heavy equipment. This method is useful for projects with large beam sizes.
Concrete-block construction
The glove and several pipes are assembled in advance in the yard into an “octopus leg” and then weighed and joined together by heavy equipment. This method is useful for projects with large beam sizes.

Accessory hardware
As a rule, loads are applied to nodes (globes) so that only axial stresses act on the member.
By adopting an integrated computer management system, CIM (Computer Integrated Manufacturing), from design to production and construction, we have achieved lower costs, shorter delivery times, and higher quality.
