Development of rigging system for prefabricated engineered wood floor panels

在过去的10年里，在多层建筑中使用木材已经引起了世界范围的兴趣。这种兴趣背后的关键因素之一是易于使用木制品进行预制，从而加快了施工速度，因为大部分施工过程可以在工厂完成。根据最近建造多层木结构建筑物的经验，建造木结构上层建筑所需的时间，约为建造类似的钢结构或混凝土建筑物所需时间的三分之一至四分之一。Giusti Wall Tech目前生产预制木剪力墙板，主要供应阿尔伯塔的建筑行业。为了抓住这一市场机遇，Giusti Wall Tech有意开发一条预制工程木地板生产线，该生产线采用工程地板托梁（如木工字梁和空腹桁架）建造。这些工程楼板托梁的长度可达20米，因此可以用于跨越几个支架，从而进一步节省施工时间。由于运输的限制，这些预制地板的宽度必须限制在3.6米，即使长度可以是最大的20米。然而，如果Giusti地板要在施工过程中实现最大的成本节约，就需要克服技术挑战。在拟议的项目中，将进行研究，以制定有效的板对板连接细节和最佳地板配置，包括索具细节，以便在工厂和施工现场进行处理。将进行计算机建模，以制定关于板与板连接细节和最佳地板配置的初步建议。然后，这些建议将通过实验室的测试程序进行验证。一旦确认，这些建议的细节将被转移到Giusti Wall Tech，以在其地板产品中实施。

Over the last 10 years there has been a world-wide interest in using wood in multi-storey building construction. Among the key factors behind this interest is the ease of prefabrication with wood products, leading to a faster speed of construction since a large part of the construction process can be done in the factory. Recent experience with multi-storey wood buildings has shown that the construction time for a wood superstructure is about one-third to one quarter of that for a similar building constructed with steel or concrete. Giusti Wall Tech is currently producing prefabricated wood shear wall panels and suppling largely to the construction industry in Alberta. In anticipation of this market opportunity, Giusti Wall Tech is interested in developing a production line for prefabricated engineered wood floor panels that are constructed with engineered floor joists, such as wood I-joists and open-web trusses. These engineered floor joists are available in length of up to 20m, and can therefore be used to span over a few supports, thereby leading to further saving in construction time. Due to transportation limitation, the width of these prefabricated floor panels must be limited to 3.6m, even though the length can be a maximum of 20m. However there are technical challenges that need to be overcome if Giusti floor panels are to achieve the maximum cost-saving in the construction process. In the proposed project research will be conducted to develop efficient panel-to-panel connection details, and optimum floor configuration, including rigging details, for handling in the factory and at the construction site. Computer modeling will be conducted to develop preliminary recommendations on panel-to-panel connection details and optimum floor panel configuration. These recommendations will then be validated by a testing program in the laboratory. Once validated these recommended details will be transferred to Giusti Wall Tech for implementation in its floor panel products.
