这种bluescope出品的淡淡蓝色的钢材叫TRUEcore,是比ZINCALUME高一个档次的。官方质保是50年。

一层

梯间采用预制PC

过梁蒙皮加强

局部型钢加强

中间双墙

折线墙体做法

局部大截面C型钢加强

桁架梁预先加工支座,方便施工。由于简支梁端头只承受剪力,只需要验算抗剪强度,所以变截面是没有问题的。

废料可以作为桁架间防扭撑杆,可以代替拉带、防扭块等。但前提是腹杆能对应起来。

OSB板做临时走道。

一层基本完成。

悬挑部位处理。

铝合金门窗可以同步生产,该系统可以保证净口误差在1mm以内。

从工厂直接将装配好的墙体结构拉过来。

吊送二层墙体。

旁边电线杆下面这个是安全员,据说一般是老板的小舅子担任,高薪职位。

根据大量实验数据,该体系的节点强度是薄弱环节,可以通过双螺丝进行节点加强,还可以节点蒙皮,还可以整体蒙皮,承载力依次增加。

桁架梁节点双螺丝。

能看到PC预制板之间采用干式连接,极少看到“等同现浇”。

下面的屋面瓦看着像彩石金属瓦。

连续桁架梁跨过型钢梁,虽然是按照简支梁计算,但是这样更方便施工。

三层完成

墨尔本当地企业总结的常见问答

Why  light gauge steel framing?
Very simply, a light gauge steel frame is a high quality product. It represents value for money and brings peace of mind带来内心的平静. A light gauge steel frame is light and strong更轻更强: it will not burn不燃烧; it is termite防白蚁, borer, and fungus-proof耐盐雾;  and it will not shrink or warp不收缩变形. It is environmentally responsible环境友好型, low on life cycle energy usage全寿命周期低碳, recyclable and saves timber resources节约木材. Steel Frame’s frame is between 33% and 50% of the weight of a comparable timber frame自重是相同木结构的33%-50%, with a far higher strength to weight ratio有更高的强度重量比. Steel features one of the highest strength to weight ratio of any conventional building product钢材是常用的强度重量比最高的建筑材料. Steel is incredibly accurate with tolerances in the 10ths of a millimetre, not in 10s of millimetres产品的精度是1/100mm级别的. Your window and door openings will be precisely placed, perfectly square (or perfectly tapered depending on your design) 你的门窗洞口要多少就是多少,分毫不差meaning fitting will be faster and easier意味着安装更快捷简便. Because steel doesn’t warp, twist, bow or settle you will experience less ‘nail pops’ requiring rectification. You will also experience drastically reduced instances of doors and windows sticking as the house settles, because a steel frame never ‘settles’, its engineered to maintain its dimensions for the lifespan of the building.

Steel is 100% recyclable (in its purest sense) and has a virtually infinite life span; it’s the most recycled product on the planet. Termite treated timber is un-recyclable (straight to landfill) and almost all other timbers are only down-cyclable.钢材是百分百回收的,是这个星球上回收最……

Steel is 100% termite PROOF, requires $0 of termite treatment and $0 of ongoing termite maintenance.较少防白蚁方面的花费

Steel is 100% non-combustible, it will not burn or ‘char’ and it will not contribute to a fire, or the spread of fire. In a bush-fire, ember attack to a steel house frame and roof space will not ignite the frame.在山火区,山火不会引燃结构框架。

 

What underlies the quality of a light gauge steel frame?
Light Gauge Steel is an engineered product, not an organic one.  Being engineered means movement over time is eliminated, as a steel frame will not settle like other products.LGS是一个预制产品,可以减少现场的管理成本。

BlueScope Steel, a quality-accredited producer to the appropriate National Standard Specifications, produces TRUECORE® steel in a Light Gauge Steel (LGS) Frame Solutions frame. The components are precision manufactured and assembled to very tight tolerances using advanced techniques. Dynamic Steel Frame uses the most advanced framing system available in the world today, combining design and engineering software and an automated roll former to produce frames, trusses and joists quickly and accurately. Strength and performance are engineered into the frame, allowing Dynamic Steel Frame to provide the best possible product to its customers.原材料采用博思格优耐板


What’s the warranty on TRUECORE® steel?

TRUECORE® steel used in IPG Steel Frame’s wall frames and trusses come with a 50 year warranty* from BlueScope Steel. A great reassurance in anyone’s book! For more information on the 50 year warranty, including the terms and conditions, visit BlueScope Steel’s warranty website.可以用50年,相关质保文件可以在truecore网站下载。

 

Will a light gauge steel frame rust?
IPG Steel Frame’s LGS frames are made of steel protected against corrosion by a hot-dipped metallic coating of a zinc-aluminium alloy. In external applications such as roofing, these products are exposed to the elements and have excellent durability, so in less exposed applications such as inside the building envelope they weather more slowly. Where there are cut edges, the galvanic action, or sacrificial protection, of the coatings protects the exposed steel edge against corrosion.会生锈吗?所有原材料采用热浸镀铝锌涂层,在切口部位,涂层会像美国总统的保镖一样,先牺牲自己。

 

Is a steel frame noisier than other stud frame buildings?钢结构比木结构噪音大吗?
No – this is one of the most ‘popular’ myths of light gauge steel framing. IPG Steel Frame’s light gauge steel frames are no noisier than other stud frames and there is some evidence to suggest the contrary. Studies conducted by CSIRO found that “most occupants of homes with steel frames either reported no sound emitted from the frame or said that if it did, it was not a problem”. In fact, some volunteered that there was less noise than previous timber framed houses.

错,没有证据表明这点

 

Steel expands and/or contracts as the temperature changes. Is this a problem?刚结构的热膨胀性能如何
In a properly constructed and insulated home by IPG Steel Frame, thermally induced movement is not an issue. Steel is engineered, inorganic, will not rot, warp, twist, bow, shrink or settle. There will be far reduced instances of plaster or cornice cracking because steel doesn’t change state during its lifespan, which means it is highly unlikely that there will be noise, and in fact, because a steel frame doesn’t settle over time you enjoy LESS issues with movement such as sticking doors, windows and so on.在做好保温构造的前提下,这不是问题

 

Termites can still attack the rest of a home so do steel frames make much difference?白蚁仍然可以攻击家里的其它东西,用你这个产品会带来什么不同?
The truth is there is nothing as catastrophic as the destruction of the primary structure of a house – the frame. Destruction of the frame by termites can be silent and invisible to the eye. Rectification of the frame can require complete replacement of other building components such as plumbing, electrical, plasterboard, skirting, architraves, kitchens, bathrooms, tiling and painting. However, Dynamic Steel Frame’s LGS frame is 100% termite-proof, ensuring no damage at all is done to the frame of the home through termites.

起码房子不会倒对吧,其它都是更换和发现更容易,结构呢?麻烦的很。

 

Can the customer erect a house frame?客户可以自己建造吗?

Sure!  The customer can install our system. Panels are easily handled and are clearly identified for assembly, with pre-punched electrical and plumbing service holes. Roof trusses are easily identified and easily secured to support the walls. Ceiling and roof battens are easily fixed to the trusses.

You don’t need to know how to be a carpenter to erect a steel frame for your house. You require far less carpentry skills to construct a LGS frame compared to constructing timber frame as you don’t need to deal with the issues of wood warping, twisting and shrinking.你不用知道那些木工知识

 

Will I be able to renovate later down the track with a steel framed house?
Yes. IPG Steel Frame’s framing allows for larger spans, meaning a home can often be designed without interior load bearing walls. This makes alterations easier without affecting the structure in any way. Furthermore the existing steel structure will remain straight and true regardless of its age, making the job of lining up the extension easier than for conventional timber framing.

你采用我们的轻钢体系,间隔可以随意变(理论上的,最好还是问问我们)

 

How much flexibility do I have with design?设计的自由度有多少
Freedom of floor plan and architectural style is practically unlimited. Dynamic Steel Frame can produce almost any 1 to 3-storey home design seen in the Australian market today, as well as being the first (and so far only!) company in Australia to construct a LGS 4-storey apartment building frame. Furthermore, it is possible to produce designs in steel that are difficult with other materials. By taking advantage of this feature, the owner can often build with less expense than by using more conventional materials.

无限。你去天马行空的想象,我们来给你实现。但是,注意价格哦!

 

Have steel framed buildings been proven over time?历史有多久了
Yes. In Australia, steel structure has been used successfully in housing since the early 1950s. The Australian steel framing industry has a well-earned reputation for being highly innovative. Dynamic Steel Frame’s LGS framing represents the results of years of research, testing and product improvement. It is a thoroughly engineered product. In responding to the needs of the Australian customer, the steel framing industry in Australia leads the world with its technology. Don’t forget that steel frames have been used in commercial buildings for many years because of their superior attributes.从1950s,应用超过半个多世纪了,技术成熟。

 

How does a steel frame perform in a fire?防火性能如何
Steel is completely non-combustible, doesn’t burn or “char” and confirms to any and all non-combustibility requirements.  Being non-combustible means the frame will not contribute to the fire or its spreading, and will not release smoke and carbon dioxide such as will happen with a timber frame.  We’ve never seen steel used in a bonfire or BBQ!

Smoke and heated air and/or asphyxiating gases are responsible for about 75% of fatalities in house fires. Steel frames will not burn.  It will therefore not contribute. Steel releases no gasses or VOCs during its life. This has been recognized by The Healthy Home Institute as a desirable feature for steel frames. Electrical faults cause many fires in wall cavities. An electrical fault cannot ignite a steel frame. If fire gets into the ceiling and ignites timber trusses it can spread very rapidly to the rest of the house. In a bushfire the point of ignition is often the roof cavity when burning embers are blown in under the eaves or tiles. House fires have been known to break through ceilings into the roof cavity. A steel wall frame or roof truss made by Dynamic Steel Frame cannot be ignited in either of these ways.75%的火灾死亡是因为烟雾。而钢是不会释放烟雾的

 

Will a light gauge steel frame perform in any climate?任何天气表现良好
Yes. Not surprisingly steel is the preferred framing material in the extreme climate of North West Western Australia, for example, where temperatures can vary more than 40 degrees Celsius in a single day.甚至日温差在40度。

 

Will my builder charge more for building a steel frame?我的建造商会多收费吗?
Competitive pricing is generally available from progressive builders for standard house designs. Progressive builders are aware that steel frames are the way of the future, and are generally prepared to quote competitively: a premium product at a competitive price.进取的建筑商,有追求的建筑商,……如果报高了,你要考虑你是不是找了个假的建筑商

 

Do homes with steel look different?
Yes, they look better. Walls, ceilings and roofs do not have ripples or bumps in them and there are no “nail pops” in the plasterboard linings. Roofs of steel-framed homes do not sag over time, even under concrete tiles, so the finished job continues to look good. Steel house frames will not change or move over time, so gaps will not open up letting air in. Insulating products work by creating a barrier between temperatures. Over time, a frame which can settle and move will create openings, which will allow air to travel through, thus rendering insulating products far less affective. Steel will not settle over time allowing other complementing products to continue performing how they were designed and specified. In fact because of IPG Steel Frame’s steel’s strength, you can design your home with larger open spaces whilst the exterior looks like any normal home, only better!

 

Does lightning strike affect a IPG Steel Frame home?防雷接地
No. Because steel is a positive conductor to the earth. The energy is conducted straight to the ground and is not released destructively within the frame as in conventional framing or cladding.

 

Is a light gauge steel frame safe when exposed to a live electric wire?
Yes. LGS frames are safe because they are earthed. It is a requirement that all new housing be fitted with circuit breaking safety devices, so there is little chance of you touching anything live. A broken or pierced wire in a timber frame can remain live and leaking current can cause troublesome faults and fire risk.

 

I am a builder.  Why should I build in steel?我是一个builder,我为什么要用LGS?因为你要追求进步啊!少年
Steel frames represent the future of house framing. Continual product improvements and consumer awareness means that demand for steel-framed homes will keep increasing. People are more conscious than ever of the ever-increasing threat from termites. You can build the major termite management into the building, rather than add it on with zero maintenance required, ever. A Dynamic Steel Frame house is a quality product that delivers to the customer long-term peace of mind and cost savings. Call backs are reduced and your reputation can be enhanced. 

Although steel frames require slightly different techniques, they are quick and easy to erect. A Dynamic Steel Frame steel wall is straight and true and has continuous nogs and flush connections, meaning cladding materials attach faster and easier. Because steel has consistent strength and complies with strict standards and tight tolerances, every stud is a good stud. LGS frames are lightweight and easy to handle, time is not lost sorting to select suitable pieces, there is no need to straighten framework on-site, and wastage of material is reduced and there is very little scrap on site. Builders will appreciate the lightweight frames being faster and easier to erect.  A 7.5-metre wall frame can easily be carried and installed by two men; trusses can be lifted into place by hand.

 

Does a steel frame interfere with radio or television reception?干扰电话吗?不!
No. Electro-magnetic waves can diffract around steel as easily as timber. Waves pass through the spaces between the studs, allowing the use of all household appliances without any interference.  Performance is no different to any other building.看来澳洲的谣言满天飞啊。电话的波长可以容易穿透墙体,可以复习初中物理《波的衍射》

 

Will Light Gauge Steel Framing affect the air quality inside my home?会影响空气质量吗?
Since steel frames do not need to be treated for termites, this makes your home a resin and chemical free environment.  As a steel frame doesn’t sag over time, gaps in the frames aren’t opened up, therefore letting in less dust.

不会的,少年

 

Does a steel frame interfere with Wi-Fi reception?影响WIFI信号吗
Steel framing is used widely all over the world. Australia is now catching up. There have never been any reports of interference and there is no reason why this should occur.没有这方面的报道

 

Can I hang pictures on my walls?挂东西
A heavy weighted picture, which will require a bolt or hanger to be used, can be screwed straight into a stud. Studs are easily located with magnets.挂东西的钉子不太一样,但很容易找到。
