这是一个骨科诊所,包括一个位于日本西部大牟田的小型住宅空间。客户希望该建筑能成为良好意义上的标志性建筑,并受到居民的喜爱。然而,预算是相当有限的。因此,需要发明一种非常合理的建筑结构和施工方法来实施该项目。

This is an osteopathic clinic including a small residential space in Omuta, the west part of Japan. The client expected a building to be iconic in a good sense and loved by residents. A budget was, however, rather limited. Thus, an invention of a very rational building composition as well as a construction method was required to carry out the project.

为了满足这些条件,我们设想了一个使用板的三角形框架。它形成了一个非常简单和合理的框架,由跨度方向的桁架部分和梁方向的连续承重面组成。此外,通过使用CLT(木质材料)作为板材,它成为一个多功能的框架,可作为结构、保温、气密和内部装饰。这样一来,二级材料(如保温层、石膏板)的使用降至最低,现场施工时间缩短,因此,建筑成本和质量可以得到优化。

To fulfill such conditions, a triangular frame using a plate was imagined. It forms a very simple and reasonable frame composed of truss section in span direction and continuous load-bearing surface in girder direction. In addition, by using CLT (mass of wood) as the plate, it becomes a multifunctional frame working as a structure, thermal insulation, airtight, and interior finish. In this way, the use of secondary materials (e.g. thermal insulation, plasterboard) is minimized, on-site construction time is shortened, and as a result, construction cost and quality can be optimized.

这个建筑由简单的三角形单元组成,由90毫米厚的CLT板组成。面板桁架作为一个单元的墙顶元素,定义了内部空间。这种简化的建筑围护结构还可以提供更多的优点,例如,易于维护和解体,从而在未来带来经济和环境效益。

This building consists of simple triangular units out of 90 mm thick CLT panels. The panel truss acts as a unitary wall-roof element defining the interior space. This simplified building envelope may also provide further merits, for instance, easy maintenance and deconstruction leading to economic and environmental benefits in the future.

板式桁架形成了清晰合理的几何形状,导致了高结构稳定性。由于这种合理的构成,面板的连接也非常简单,只需使用螺丝。由于这是一种独特的方法,所以用一个模拟的接头来测试接合强度。

The panel truss forms clear and reasonable geometry resulting in high structural stability. Thanks to this rational composition, the joints of the panels are also very simple using screws only. Since it was a unique method, jointing strength was tested using a mock-up of the joint.

由于三角形单元在结构上是独立的,它们是通过逐渐地相互移位来放置的。单元之间的缝隙导致空气和光线进入室内,并给予空间上的扩展。三角形单元看起来像一个传统的坑式住宅,内部空间感觉像一个木制洞穴。建筑的扩展也相当容易,因为单元的屋檐一侧被木墙和玻璃所覆盖。

As the triangular unit is structurally independent, they are placed by gradually shifting each other. The gaps between the units lead to air and light to the interior and give spatial expanse. The triangular unit looks like a traditional pit dwelling and the interior space feels like a wooden cave. An extension of the building is also fairly easy since the gable side of the unit is covered by a wooden stud wall and glazing.

大量的木材,如CLT和GLT,可能有可能再次简化和合理化基于木材固有特性的建筑构成。传统和现代建筑解决方案的结合可以为可持续现代建筑的进一步发展提供一个有趣和有利的方法。

Massive timber, such as CLT and GLT, may have the possibility to again simplify and rationalize the composition of a building based on the inherent properties of wood. A combination of traditional and modern building solutions could offer an interesting and profitable approach to the further development of sustainable modern buildings.
