Concrete benefits

As well as providing the structural frame, concrete can be used to improve the overall performance of a retail building, including:

防火

固有fire resistance意味着混凝土结构通常不需要额外的防火。这可以消除时间，成本，使用单独的贸易和持续维护以应用防火。

Concrete can offer fire protection greater than that needed for life safety for little or no extra cost. By increasing the fire protection it is more likely that the building can be repaired and be ready for trading again at the earliest opportunity. For more information on concrete's performance in fire, see混凝土和消防安全出版物。

适应性

市场和工作实践不断常ing, therefore it makes sense to consider a material that can accommodate changing needs or be adapted with minimum effort. A concrete frame can easily be adapted to other uses. Holes can be cut through slabs and walls relatively simply, while there are methods to strengthen the frame if required.

服务

机械和电气服务是建筑中昂贵且至关重要的元素，并具有重大维护和替换问题。混凝土扁平板的拱腹为服务分配提供了一个没有任何倒立光束的区域。这减少了设计团队的协调工作和错误的风险。它可以灵活地设计和适应性。平坦的拱腹允许最大的服务，更高质量的工作和更快的安装。M＆E承包商在剖析的拱腹下方引用了额外的水平服务分配成本，其横梁高达15％。

在设计过程中，可以简单地容纳平板上的服务立管的开口，并在铸造过程中形成或以后切割以适应。对于最长的跨度，宽的浅梁溶液提供了不间断的次要梁的大面积，以及在浅主梁下方的管道自由。

混凝土解决方案

Concrete offers a whole range of options for meeting the requirements of a particular project. The options outlined below are the most popular for retail buildings. More information on concrete frame solutions can be found in混凝土框架和出版物Economic Concrete Frame Elements。

Flat slab

平板are slabs that are supported directly on columns without any beams. They are highly versatile elements widely used in construction, providing minimum depth, fast construction and allowing flexible column grids.

后张紧平板

张贴后是一种提供最薄的平板类型的预应力的方法，因为混凝土的优势是在压缩的。由于预应力可以实现更长的跨度，该预应力可用于控制挠度。有关后张紧后的更多信息可以在出版物中找到张紧的混凝土地板。

混合混凝土结构

混合混凝土施工(HCC)makes use of precast and in-situ concrete together, combining the benefits of both to give a robust, durable construction which is fast on site, with an excellent finish. There are many different forms of HCC but a popular option for retail buildings is to use hollowcore units, which are prestressed to maximise the floor span.

覆层

预制混凝土覆层提供了一种具有成本效益的方法，可以提供健壮的高质量外墙，并提供各种耐用的质地，颜色和图案，包括一系列面对面的材料，例如石材和砖块。它也被称为建筑预制混凝土覆层。自生产的建筑混凝土使用精心选择的天然材料范围，有时被称为“重构石头”或“侦察”，因为外观比石头更类似于石头的外观。在覆层页面。
