抗震

The earthquake resistance is a key point when building houses in 日本, 哪个地区经常发生地震. 十大赌博娱乐平台在各种地震波下对海姆进行了测试, 包括带1的波,800年加, which is twice as strong than those observed during the Great Hanshin Awaji Earthquake. Heim demonstrated that the structure remains undamaged, 即使遭受更强烈的地震, 连续数天反复发生.

全尺寸检验

全尺寸检验 of real residence assuming actual life

Approximately the same model building to a comfortable Parfait house, 有一个大开口的窗口, heavily tiled external walls and a wide balcony was built for the test. 家具重量估算,60kg/m2 还增加了负载. Although full-size tests featuring the building repeatedly subject to violent vibration represent hostile conditions, we nevertheless plan to conduct tests under such conditions.

Tests under different seismic waves, such as inland and interplate earthquakes

The Great Hanshin Awaji Earthquake was known as an inland earthquake, occurring near cities with very strong instantaneous shock waves. 另一方面, 东海地震, 预计在不久的将来会发生什么, 可能是板块间地震. This type of earthquake has its hypocenter under the sea and the quake continues for longer than that of an inland earthquake, meaning the consequent damage to buildings may be greater.

十大赌博娱乐平台在各种地震波下对海姆进行了测试 of inland and interplate earthquakes and confirmed its safety following each seismic wave.

Tested against great shocks equivalent to earthquakes occurring within tens of thousands years

We carried out full-size tests for Heim under various seismic waves for three days. 作为板间地震试验, 6 seismic waves from the Miyagi Offshore Earthquake and 25 seismic waves from the predicted Tokai Earthquake were used for the tests. 在其中的四次测试中, 1,330年加, 振动器的最大容量, 被反复应用到建筑上. 用于内陆地震试验, 18 seismic waves from the Great Hanshin Awaji Earthquake were used for the test. 在其中的8个测试中, the seismic waves applied were greater than those of the real earthquake having occurred in the past. 最大的一波,800年加, which is 2 times greater than the figures observed in the real earthquake and 振动器的最大容量, 也适用于建筑吗. 测试总数为49. 这样的条件, 即地震的数量和规模, 不会影响任何建筑物吗. 然而, 海姆展示了它的实力, even under circumstances faced with several aftershocks coming after the main shock for example.

海姆具有不可估量的抗震能力.
Tests were carried out under conditions approaching the limit of the testing machine system.

主要测试量表

单元结构

Even a single unit can withstand the force of an earthquake equivalent to the largest magnitude in centuries

When a building is exposed to shocks from an earthquake, the force is concentrated on the joints. 海姆的部队, posts and beams are welded through joint-pieces (steel plate reinforcement) and it forms a box frame structure* with integrated posts and beams. 不像普通的框架结构, where the posts and beams are jointed with bolts, this is a very strong structural unit with no weak areas. 除了, the posts and beams are always made to form rectangles, in order to minimize the deformation and damage of the building incurred.

Combined units become even stronger, with jointed 2 or 4 posts and beams

The strength of a post and beam depends not on the thickness but on the sectional area. When a Heim's strong single unit is connected to other units, 关节的单位变得更强, with 2 or 4 posts and beams forming large sectional areas. 特别是, 第二层的楼板横梁, which are exposed to the maximum shock from the earthquake, 形成的截面面积可达350mm × 150mm. This unit structure will be able to cope with the seismic intensity from the largest earthquake.

单位s are firmly connected with high-tension bolts usable for bridgework

海姆由几个联合单位组成, between which the joints are firmly connected via high-tension bolts. 这些高强度螺栓, 直径16毫米, with semi-permanent strength and usually used for bridgework, 是用来垂直连接单元的吗. 8个螺栓,每个螺栓可承重1吨.8kn) of shear force, connect units horizontally, while four anchor-bolts, each bearing 2.2 (21.6kn) ~ 12.2吨(119吨).6kn) shear force connect the entire unit to its foundations. Every unit and set of foundations are integrated into a single strong structure without any weak area.

Every bolt is managed for the torque to be fixed as calculated in order to exert maximum strength.

The flexibility of the box frame structure and external walls that absorb earthquake energy prevent sudden destruction, 即使暴露在最大的地震运动中.

Heim's box frame structure, like a high-rise building, absorbs earthquake energy by bending slightly. The external walls also have a structure capable of absorbing the earthquake energy. With this box frame structure and the external walls, the acceleration (response acceleration) to which the building is exposed diminishes compared to that of a brace structure building, which resists the acceleration by its own strength.

When the box frame structure building is exposed to the maximum earthquake energy, 由此产生的加速度更小, 这意味着它避免了突然的破坏, unlike buildings using their own strength to resist this energy. Focusing on potentially falling furniture and remaining inside the building until the quake stops may therefore be safer than evacuating outside.

外墙

独特的外墙可以吸收地震

每个外墙材料轻微变形, synchronizing to the quake affecting the building structure, and the entire external walls absorb the seismic shock. 与此同时, the gasket masonry joints method is adopted for the joint external walls and these gaskets also function as shock-absorbing material. When the building structure reverts to its normal shape after being subjected to the violent stresses of a great earthquake, the structural design also allows the external walls and gasket to return to normal conditions. There is little fear of the external walls cracking or falling.

The outer wall materials are fixed between posts with special clasps called studs, which are designed to absorb the energy from seismic shocks. The effect of the quake is thus also decreased by the energy absorbing effects.

Using lightweight members to control the shock of the building

Seismic motion comprises various elements, including amplitude, period and velocity. 特别是, acceleration (gal) is closely related to the force exerted on a building. The relationship between the acceleration and the force to which a building is exposed can be expressed as: Force added to building = mass of building x acceleration. The larger the mass becomes, the stronger the shock becomes. 通常, 贴瓷砖的外墙相当重, but we use our own developed lightweight and flexible SFC boards (cement rich surface and wooden chip rich inside). 除了, 十大赌博娱乐平台也使用降噪地板, developed in-house without ALC or concrete boards and bruck roofing material that is half the weight of 日本ese roof tiles. The use of such lightweight members to reduce damage is incorporated into every part of Heim.

Full size tests using real residences revealed no damage or falling tiles.

It is estimated that many tiles used for ordinary houses will be prone to damage or falling at seismic intensities of 6 or lower. 然而, each one of the Heim external wall tiles is affixed to the strong and flexible SFC boards using elastic adhesives. Furthermore, adhering work is carried out in factory with carefully controlled humidity. 因此, the strength and stability of the adherence are far superior to those applicable to on-site work. No damage or falling tiles were observed during full size tests involving exposure to forces 2 times stronger than the shocks during the Great Hanshin Awaji Earthquake

We use a mat foundation that bears a load over its whole surface and is a structure spreading the seismic force to the ground

The mat foundation has attracted attention since the Great Hanshin Awaji Earthquake and is used in Heim as one of the standard features. 不像连续的立足点系统, 它通过一根线承受载荷, via which seismic force is channeled into the ground, the mat foundation bears load over its whole surface and seismic force flows from the surface into the ground to protect the building on its foundation. The mat foundation thus has superior earthquake resistance as well as functions to control the liquefaction phenomenon and differential ground settlement, 有助提升楼宇安全.

Solid foundation of Heim (force to ground is low)
The solid foundation scatters force from the construction load and it is effective for ground with a high soil bearing capacity (less than 50kn/m2)
Continuous footing of ordinary housing (force to ground is high)
液化
液化 means the settlement of ground that occurs when water-containing soils are parted by the quake, 浮在水中, 然后沉.
不均匀沉降
The differential settlement means a phenomenon whereby the ground cannot bear the construction load and differentially sinks, 因此导致建筑倾斜.

Heim demonstrated the ability to reduce quake impact during full size tests

The figure for acceleration (gal) shows the magnitude of ground motion caused by the earthquake. 响应率, 与此同时, shows the value indicating how many times the acceleration to the foundation is magnified and reaches each floor. The smaller the value, the more the building is stable and further the damage is minimized. 响应率 of Parfait was measured as a ratio of 1.全尺寸测试时二楼有36个. This value is much smaller than ordinary houses built using conventional buildings. The stability and strength of Heim to resist earthquakes are therefore verified in its design.

与此同时, Members of units contributing to the load bearing and durability qualities of the building are manufactured with a high degree of accuracy by using the latest high-tech machine tools. The level of errors made during manual work performed by skilled on-site workers is generally estimated as around 5%. 在十大赌博娱乐平台的海姆生产工厂, 然而, the use of all the members of units and parts is specified, pre-inspected members and parts are always used and the number of orders placed from building sites are strictly limited. 除了, specialized inspectors thoroughly inspect 250 items. Thus we implement perfect quality control for manufacturing and building Heim, to ensure it is designed without variation or errors.
