[Prior art]
With the rapid change of social structure, traditional ways of thinking are being abandoned in many working methods. For example, the building construction method has already come to adopt precast concrete products standardized as much as possible or to use an effective combination method when planning architectural design. This is because, in this way, it is possible to improve many problems such as on-site construction safety, environmental hygiene, shortening the construction period, and simultaneous procurement of technical personnel and materials.
However, not all construction or civil engineering work processes are suitable for adopting a precast concrete method. It depends solely on whether the needs for structural safety, construction costs, construction possibilities, transportation convenience, etc. can be met. A cast-in-place concrete method and a precast concrete method combined by a general building design engineer or a building construction engineer according to the situation are a good method for overcoming many constraints. In other words, the precast concrete method is one of the important methods that must be used in many construction works.
[0003]
In recent years, IT technology has been a driving force in the economy, and as a result, the demand for components that make up hardware such as integrated circuits, which is the core of IT technology, has risen in a straight line. Yes. Because of this situation, the indispensable condition for investing in a hardware parts manufacturing factory and building a factory is “time”. In other words, the construction principle of the parts manufacturing plant is not only that the structure, construction safety, etc. meet the regulations of the building law, but also the planned completion, that is, whether the construction period can grasp the best time to secure profits. It is an element.
Generally, since the hardware component manufacturing factory requires the deployment of equipment, processing machines, etc., a waffle slab layer used for the deployment is installed. The waffle slab layer is a slab layer whose floor is raised by a support column. In the conventional slab layer construction of a hardware parts manufacturing factory, the column body is first constructed on the spot, and then the formwork is assembled after the column body is completed. Place the rebar. Subsequently, concrete is cast to complete the slab layer. This construction method has a long construction period, and also creates a collision in the process progress with other construction on the site.
[0004]
[Problems to be solved by the invention]
In order to solve the drawbacks of the above known construction methods, an object of the present invention is to provide a precast concrete waffle slab structure of a hardware component manufacturing factory.
In the hardware parts manufacturing factory, the entire waffle slab layer where equipment, processing machines, etc. are installed is manufactured by precast concrete construction and the structure is assembled. Precast concrete waffles are supported on several upright columns. Combining slab layers. In addition to meeting the needs of various equipment installations, this structure can shorten the construction period and can greatly reduce the number of on-site construction man-hours in the construction of a hardware component manufacturing factory. In this way, structural safety, fire and seismic performance, transportation convenience, rapid construction and aesthetics are achieved.
