[Technical field to which the invention belongs]

 The present invention relates to a slab structure, which is applied to install electronic component manufacturing equipment and a processing machine in a factory for manufacturing electronic components such as integrated circuits (and to be used for other purposes). The slab structure has structural safety, reasonable construction cost, quick production, convenient transportation, easy construction, simple structure joining method, and the like.

[Prior art]

 As the semiconductor market is constantly changing, the crucial condition for the construction of a factory for manufacturing electronic components such as integrated circuits is `` time ''. You have to seize it. Since the integrated circuit and other electronic component manufacturing plants need to be equipped with equipment and processing machines, the slab structures in the manufacturing plants must resist micro-vibration, and the special slabs are not the same as lattice beam slab structures. I have no choice. Lattice beam slab structures can be applied not only to electronic component manufacturing plants such as integrated circuits, but also to other structures that are required to resist micro vibrations, or to long beam spans, and to grids with high column heights. It is also applicable to beams (called Waffle Slab).

Conventionally, in the construction of a lattice beam slab structure in an electronic parts manufacturing plant such as an integrated circuit, a form of the lattice beam slab structure is first assembled at a site with a layer raised by temporary columns, and a reinforcing bar is arranged. You. Subsequently, concrete is poured and the lattice beam slab is completed. In addition, a grid will be provided on the lattice beam slab structure, and equipment and processing machines will be deployed. The plurality of through holes formed in the lattice beam slab layer can be used for applications such as air circulation and pipeline penetration. (The use of a plurality of through holes formed in the lattice beam slab layer is a known technique, and need not be particularly described.)

The conventional lattice beam slab construction method is susceptible to the weather because of on-site construction, making it difficult to work at heights, and large-sized temporary supports affect the process flow line, thus lengthening the construction period. , Have a significant impact on business opportunities. In order to reduce the number of processes that are concentrated on the construction site without being affected by the weather and to improve the quality, the construction work process is gradually moving toward precasting. However, when using the precast method in the construction work process, it is necessary to pay attention to the structural safety and cost limitations in the production, transportation, building, and joining of the structures. Even if the precast method is used for the lattice beam slab, it is difficult to structurally join the slabs vertically and horizontally, and since the lattice beam slab structure is long and heavy, it is produced and transported. , Which significantly increases the cost of building. Due to safety and cost limitations, the precast method has not been adopted in the past, and the construction period of electronic component and other electronic component manufacturing plants has been lengthened, making it difficult to solve the difficulties in ensuring construction quality.

[0005]

[Problems to be solved by the invention]

 The main purpose of the present invention is that the bottom of the slab is manufactured by precasting first, then it is moved to the site and the secondary construction is performed, and the weight of the precast part of the lattice beam slab can be reduced, It is convenient for transportation and building, and by casting concrete on site (ie, secondary construction), it facilitates joining of slabs and slabs to the bottom of a half precast slab, and An object of the present invention is to provide a slab structure that can omit a large number of temporary columns for supporting concrete weight and construction load, and that can maintain a good process flow line.
