Case 1 weather resistance technology of precast steel structure residence with ponding in Japan

In the welding part, the magnesium in the gold plating layer also melts to the repaired metal surface to form an effective protective film, providing sacrificial corrosion protection for the cutting surface and processing parts.

Characteristics of ZAM anti-corrosion technology if the steel frame is damaged, the zinc, aluminum and magnesium in the gold plating layer will melt, thus protecting the steel (this is called sacrificial anti-corrosion).

About the weather resistance technology of the cast steel structure product “seeper Haimu” of seeper residence in Japan, this paper explains it from three aspects: exterior wall materials, structural units and roof materials.

3 roofing materials for flat roof Heim’s hyperdulatic roof has super long durability and high weather resistance.

Erection Anchor

exhibited the combined residential “seeper Haimu” at the “Tokyo international high quality home exhibition”, and began to sell the world’s first industrialized precast steel structure residential “seeper Haimu (steel structure)” in June of the next year.

Dura stone wall is impervious and does not need coating because it is composed of fine particles and has very small independent bubbles.

The maintenance of the roof only needs to seal the inclined roof.

It also has high hydrophilicity, which can prevent the adhesion of oily dust and grease such as automatic exhaust.

The corrosion resistance of this material is about 4 times higher than that of ordinary stainless steel used for external components.

All columns and beams of Heim are coated with ZAM, which helps to extend the durability of the steel, which means that its corrosion resistance is twice that of ordinary molten zinc aluminum plating *, and its expected service life is up to 140 years.

Ordinary plastered exterior walls need to be repainted about every ten years, while the UVA coating used for Heim’s exterior wall adopts a special process to apply a thick transparent finish containing ultraviolet absorbent on the colored base (enamel base).

The accumulated water uses ZAM steel plates that meet the deterioration control level 3 and 75 year durability standard to build all steel frames of Heim, which means that the 75 year durability of ZAM steel plate frame structure has been verified according to the quality safety law.

For anti ultraviolet and acid rain, considering the weather conditions in Japan, it may be the most suitable exterior wall material, which will change greatly from winter to summer.

Once the water diffuses to the whole surface, this can prevent the stains caused by rainwater from sticking to the surface.

The coating can allow a small amount of ultraviolet rays to penetrate into the enamel substrate, and extend the recoating interval to about once every 20 years, which is twice that of ordinary painting, so as to maintain the appearance and waterproof performance of the external wall.

Anti condensation design the condensation in the wall will accelerate the aging of the structure and reduce the thermal efficiency of the building.

Heim’s interior walls prevent moisture from entering the room because they are made of moisture-proof gypsum board.

In addition, since Heim’s columns and beams are produced and assembled in the factory, the actual service time may be longer without exposure to outdoor air.

This feature and its durability reduce the maintenance costs involved.

Comparison between UVA coating and ordinary coating dura stone wall dura stone wall is similar to stone in composition and does not need to be repainted.

The ordinary tile roof needs to be repainted every 10 years, and the roof or roof tiles should be replaced every 30 years to maintain the beauty and waterproof of the building..

What is hydrophilicity? Hydrophilicity means the formation of a thin water film on the surface of the material.

UV has an adverse effect on the paint film of the exterior wall, reducing the waterproof performance and damaging its beauty.

In October of 1970, seeper Chemical Industry Co., Ltd.

Durability is the key to prevent the deterioration of structures and building members over time and to maintain the safety, comfort and health of family members.

Dura stone wall is made of kaolin, a natural material used in medicine and cosmetics.

For these purposes, tiles are bonded to the waterproof SFC board using a waterproof elastic epoxy adhesive to eliminate sharp corner joints.

Ponding tiles are used in Heim’s exterior walls to improve durability and waterproofing.

Since the tiles used by Heim have fine surface irregularities to maintain their high hydrophilicity, they can be kept clean for a long time, and unlike painted exterior walls and wallboard exterior walls, this can greatly reduce maintenance workload, such as redoing waterproofing and repainting.

Tiles are fixed in place in the factory to maintain constant performance quality.

In case of invasion, the semi sealed cavity between the plates can drain water and keep the interior of the wall dry.

The anti-corrosion treatment adopted has a significant impact on the durability of the steel frame.

The unit technology of the structural unit ZAM coated steel plate to protect the steel frame and the ZAM coated steel plate to keep the performance stable for 140 years.

UVA coated embossed exterior wall with UVA coating doubles weather resistance.

Kaolin is first burned to extract impurities, crushed, mixed with hardener, filler and foaming agent, and then foamed and hardened through chemical reaction.

Among ordinary gold-plated and painted steel plates, only 2.3mm thick ZAM steel plate can reach the grade 3 standard for deterioration control, with 75 year durability· * deterioration control level 3: measure level to extend the period of major modification, such as replacing materials used for structural framework· * service life: the number of years that the maintained structure reaches the aging limit.

Maintenance cycle of exterior wall materials: once every 30-40 years, ceramic tiles are excellent materials for exterior wall decoration, with high-quality appearance and performance of preventing ultraviolet and acid rain.

Facts have proved that the corrosion degree of this material is less than 0.2mm per century, even in Okinawa and other areas damaged by seawater.

ZAM steel plate ensures that it meets the most stringent durability requirements under the quality safety law and reaches the deterioration control level 3.

Stainless steel roof materials used for ponding are also used in dome buildings and large buildings.

A case study of Guo Mai’s rural construction, green construction, old-age housing policy and technology observation on the weatherability of ponding housing in Japan “ponding Haimu M1” is sekisuiheimm1 in English.
