Advantages in CMU / No Beam / No Load Bearing Wall Design

There are differences in structural requirements of structures in US and China. Reinforced concrete block for walls, lintel and column are not acceptable in China. CMU is not allowed in China for building structural purpose. Concrete column and plate construction with no supporting beams method is also not acceptable in China.

Using concrete blocks in construction for structural purpose instead using pour-in-place concrete can save construction time and formwork hence fast in delivery time with less cost. Using reinforced concrete block method can achieve similarly like reinforced concrete the required fire-rating and protection from insects and security from break-in.

With no-supporting beam, plate and column construction method was first publicized by Le Corbusier’s Domino House design in 1914.

It has great design advantage that without beams thus giving freedom to design the interior layouts otherwise interfered by beams. More flexibility in interior layout if load-bearing walls are also eliminated. Wall and partition can have a wide range of choice of building materials that can include masonry, steel stud and gypsum wallboard or glass plate. They all make future changes including adaptable other use more possible.

More sunlight and daylight can be brought into a room if the top of its window is without a beam across it.

There are savings in construction cost and time in plate and column construction method comparing with supporting beam construction method.

Here I introduce a townhouse which adopted steel reinforced CMU construction method for supporting wall and steel C-joist for flooring support. The townhouse is for one family use plus commercial use on ground floor with a cellar. It has 9550 square feet total and it is located in New York City. New York City Building Code requires compliance to Seismic Zone 2 standard (vs Zone 4 for California).

The project consists of 60 sheets of drawings including those for zoning application and building specification. In the presentation of the project here, working drawings are partially presented which were all drawn in ink with lead letterings all by myself. Color and annotations are added for this presentation.

CMU混凝土砌块、无梁、无承重墙设计的优势

美国和中国结构的结构要求存在差异。中国不允许使用混凝土砌块作结构用途。中国加筋混凝土砌块墙,连梁和柱是不可接受的。 没有梁的混凝土立柱和板结构在中国也是不为接受。

在建筑结构中使用混凝土砌块,而不使用现浇混凝土,可以省去拼模板的工作时间,从而加快施工,降低成本。

采用加筋混凝土砌块方法的建筑,同样如钢筋混凝土建筑可以达到建筑所需的防火等级,防虫和防盗的功能。

无梁,钢筋混凝土柱和板的施工方法,最早是由勒·柯布西耶的Domino House设计在1914年公布。

无梁具有很大的设计优势,可以自由地设计内部布局,否则可由梁和承重墙壁的干扰。如果承重墙也被消除,内部布局的灵活性将会更大。

不承重墙和隔墙可以有广泛的建筑材料选择,包括砖石,钢龙骨石膏墙板或玻璃板。他们都使未来的变化,包括适应其他用途更多的可能。

如果窗户的顶部没有横梁,则可以将更多的阳光和日光带入室内。

与梁施工方法相比,柱板和施工方法的施工成本和时间为节省。

在这里介绍一个采用加筋混凝土砌块墙施工方法的联排别墅,用于支撑地板支撑的钢C型托梁。联排别墅是一个家庭使用,另外在一楼和地下室为商业用途共有9550平方英尺,它位于纽约市。纽约市建筑规范要求符合地震2区标准(加利福尼亚州为第4区)。

项目整套60张施工文件,包括用于分区(Zoning)和建筑规范申请及施工的图纸和规格资料。在这里整套施工图纸作部分介绍。图纸全为本人用墨水针笔画图和铅芯笔书写。为此演示图纸添加了颜色与注释。
