Made in Japan
Manufacturer: Tomoe Seisakusho Co., Ltd.
Product name: Steel Square Stopper

What is a steel square stopper?

Steel square stoppers are one of the supporting members of concrete railway bridges (installed on girders and abutments/piers), and are used as a set of fixed stoppers and movable stoppers.
The horizontal force along the bridge axis is absorbed by the fixed stopper, while the force perpendicular to the axis is handled by both the fixed and movable stoppers.

Features

Shortened delivery time (comparison of our painting specifications)

Aluminum/magnesium alloy thermal spraying shortens the rust prevention treatment of steel square stoppers by about a month compared to traditional painting.

Improving construction workability and quality

The steel square stopper is installed on site by filling the steel pipe with concrete.
Conventional products have a small filling port, which makes work difficult, and it is also difficult to check the filling level, which affects strength, from the small filling port.
Therefore, we solved the above problem by maximizing the filling port (equivalent to the cross section of the steel pipe).

Significantly reduces man-hours after installation

In order to position the receiving box of the steel square stopper on the movable side, in conventional products, the steel pipe body and receiving box were fixed by welding with a temporary fixing plate.
Therefore, after installation, it was necessary to cut the temporary fixing plate and paint the cut part, which increased the number of man-hours on site.
Therefore, we have adopted a structure in which the receiving box is positioned using bolts with slits, and the slits are cut by the horizontal force of girder contraction, reducing the number of man-hours on site.

Tomoe Steel Bar Stopper

kvt part2 — Sat, 29 Feb 2020 03:25:45 +0000

Made in Japan
Manufacturer: Tomoe Seisakusho Co., Ltd.
Product name: Steel Bar Stopper

What is a steel bar stopper?

This is a support member used for adjustment girders (Gelber girders of rigid-frame viaducts) to smoothly transmit horizontal force between upper and lower structures of concrete railway bridges.

[Performance]

Movement restriction device is utilized to control the expansion and contraction of the girder caused by temperature changes, etc.

A device is implemented to prevent bridge collapse during earthquakes.

*In road bridges, it may also be referred to by names such as anchor bar or anchor device.

Tomoe TS Type Insulation Bolt

kvt part2 — Fri, 28 Feb 2020 04:34:39 +0000

Made in Japan
Manufacturer: Tomoe Seisakusho Co., Ltd.
Model: TS Type

Features

Insulation sleeves serve the purpose of insulating..No problems such as peeling or pinholes occur.

Since the outer diameters of the sleeve and screw are almost the same, there is no need to drill bolt holes for the flange.

The insulation sleeve utilizes fluorine resin for its construction.It has high insulation resistance and excellent weather resistance and mechanical properties.
You can choose materials for bolts and nuts based on the application, including options like stainless steel, ordinary steel, or high-tensile steel.

Since this product is customized, it can be manufactured to meet your specific size requirements.

[Versatile type that can be used in all directions]
Suitable for applications with high functional requirements.(Example) Water supply and sewerage, bridges, air conditioning, gas, oil refinery, power plants, etc…
