Description
THE PREFABRICATION OF THE WAFFLE SLAB IN WAFER
FOUNDRY (FAB) BACKGROUND OF THE INVENTION
Field of Invention The present invention relates to a prefabrication of construction waffle slabs in a building and, in particular, to a prefabrication of the waffle slabs for a wafer foundry.
Related Art Upon rapid changes of the society, many operations have abandoned traditional wisdom and routines. For example, the construction method has been changed in such a way that standardized prefabricated products or effective assembly methods are employed so that all problems at the construction site such as safety, sanitation, schedule, gathering of technicians and sufficient materials can be improved.
However, not all constructions or civil engineering can be readily achieved by prefabrication. It depends upon whether the methad satisfies the requirements of safety, cost, construction feasibility, and transportation etc. The combination of on-site construction and prefabrication has been widely adopted by architects and engineers as a valuable method to conquer all sorts of limitations. Thus, prefabrication plays an important part in both civil engineering and building construction.
Nowadays information technology has assumed the lead in global economy.
The need for wafers-the spinal core of information technology has increases abruptly.
Therefore, the primary concern of investing wafer foundries is high efficiency in the process of construction. That is, aside from satisfying the civil engineering code, labor safety codes and etc, the ability in mastering the construction schedule will decide the profit for the investors. Usually, the wafer foundry or fab is equipped with waffle slabs for the installation of machines and devices. The waffle slab is a slab supported by pillars (or columns). In traditional fab slab construction, the pillars (or columns) are cast in place on the job field. Once the pillars (or columns) are constructed, wood molds and reinforced steel bars are assemble to be topped with concrete, therefore forming the slab. This method demands longer construction period and may delay other construction works.
SUMMARY OF THE INVENTION
This invention manufactures the waffle slabs mentioned above for the installation of machines and devices in a prefabrication way so that they can be assembled on site.
By assembling numbers of prefabricated pillars (or columns) and the corresponding prefabricated waffle slabs, aside from complying with various requirements for installing all sorts of machines, this invention can also shorten the construction schedule to the optimal one and greatly reduce the on-site construction of the waffle slabs. Thus, we can achieve the goals of having a safe, fireproof, quake-tolerant and artistic structure with easy to transport, fast to construct prefabricated waffle slabs.

DETAILED DESCRIPTION OF THE INVENTION
The prefabrication of waffle slabs for a fab (wafer foundry) is composed by numbers of prefabricated pillars (or columns) ( 1 ), which have rectangular capital on top of each columns pillar (or column) (1) is positioned upright at the proper position.
Square prefabricated waffle slabs (2-9) in various embodiments are placed on the prefabricated pillars (or columns) ( 1 ) so that notches on the four corners of each square prefabricated waffle slab 2-9 can be positioned on the capital (11) of the pillars (or columns) (1) either directly or by assembly. This method forms a wide variety of waffle slabs for a fab.
As shown in the drawings, the first through fourth embodiments and the first and second embodiment resemblance objects of the present invention are entirely prefabricated. That is, these prefabrications of waffle slabs (2, 3, 4, 5 & 7, 8) are prefabricated in the factory to their complete shapes. Once they are shipped to the construction site, one needs only to place them on the pillars (or columns) (1) or install them on the pillars (or columns) (1) through assembly elements without the need of tiding reinforced steel bars or pouring concrete. The fifth embodiment of the invention and the resemblance object are partially prefabricated. That is, these S prefabrications of waffle slabs (6, 9) are made partially into shape. The waffle slabs are then embedded with small cylinders (63) and/or multi-cylindrical post connectors (65). Once they are shipped to the construction site, reinforced steel bars and concrete are provided to complete the formation.
As shown in FIGS. 1 through 4, the square prefabricated waffle slab in the first embodiment of the invention has notches on four corners (21 ), regular patterned holes (22) are arranged on the upper surface and a rectangular hollow shape (23) on the back. Upon fulfilling the structural requirements, the hollow space can reduce dead loads and materials. The prefabricated waffle slab (2) are securely positioned among all arranged pillars (or columns) ( 1 ) to form a safe structure of the waffle slab for a 1 S fab.
As shown in FIGS. 5 through 8, ladder-shape auxiliary (31) that is formed with holes (32) are introduced to accurately place the trapezoid-shaped waffle slabs longitudinally and transversely on top of prefabricated pillars (or columns) (1). The T-shape prefabricated waffle slabs (3) are then placed into the corresponding ladder-shape auxiliary (31 ) for its proper positioning. The upper surface of this T-shape prefabricated waffle slab (3) is cast with cylindrical holes (33) and the back surface of it is equipped with reinforced beams (plates) (34).
As shown in FIGS. 9 through 12, dove-tail-shape auxiliary (41) are installed transversely on the prefabricated pillars (or columns) (1). The rib-shape prefabricated waffle slab (4) of the third embodiment is then installed and positioned on the dove-tail-shape auxiliary (41) by both ends. The upper surface of the rib-shape prefabricated waffle slab (4) is fabricated with numbers of ribbed plates (42) and the back of it is equipped with trapezoid-shaped reinforced beams (or plates) (43).
As shown in FIGS. 13 through 16, the M-shape prefabricated waffle slab has employed T-shape auxiliary (51 ) which has protruding blocks (52) that is to be installed transversely on the positioned prefabricated pillars (or columns) (1). The M-shape prefabricated waffle slab (5) is then installed in the right position by matching both ends onto the protruding blocks (52) of the T-shape auxiliary (51).
The upper surface of the M-shape prefabricated waffle slab (5) is cast with square holes (53) and the back of it is equipped with trapezoid-shaped reinforced beams (or plates) (54).
As shown in FIGS. 17 through 20, a thin slab shape (61) is introduced as the upper rim in the partially prefabricated disk-shape waffle slab (6) of the fifth embodiment. The thin slab shape (61 ) which is cast with numbers of cylindrical holes (62) for the embedding of small cylinders (63) (auxiliary cylinders made of lightweight plastic) that will bond with the disk-shape prefabricated waffle slab (6).
The central portion is formed with square troughs (64) to be embedded with the multi-cylindrical post connectors (65) which will bond with the disk-shape prefabricated waffle slab (6) also. The finished object of the partially prefabricated embodiment is shown in FIG. 19. Once they are shipped to the construction site and installed on the pillars (or columns) ( 1 ), concrete is then provided to form a slab just like the entirely prefabricated waffle slab (2) in the first embodiment shown in FIG. 3.
The characteristic of the partially prefabricated waffle slab is that it has a lighter weight than the entirely prefabricated one under certain strength requirements.
Therefore, the transportation, shipping and construction of the slabs are easier than the entirely prefabricated ones. Furthermore, the conjunctions of the partially prefabricated waffle slabs are simpler than the entirely prefabricated slabs.
However, the disadvantage is that one needs to place reinforced steel bars and to cast concrete on the site.
As shown in FIGS. 21 through 24, the square prefabricated waffle slab (7) can be made in resemblance of square prefabricated waffle slab (2) in the first embodiment.
More explicitly, the resembled square prefabricated waffle slab (7) is made as a solid with cylindrical holes (71 ) distributed thereon.
As shown in FIGS. 25 through 28, the square prefabricated waffle slab (8) can be made in resemblance of T-shape prefabricated waffle slab (3) of the second embodiment. More explicitly, the ladder-shape auxiliary (31 ) is has not been changed, but the resembled square prefabricated waffle slab (8) is made into solid with through cylindrical holes (81 ) thereon.
As shown in FIGS. 29 through 32, the partially prefabricated disk-shape waffle slab (9) can be made in resemblance of the partially prefabricated disk-shape waffle slab (6) of the fifth embodiment. More explicitly, the rectangular holes (67) in the central portion are changed into a row of cylindrical holes (91 ) on the resembled partially prefabricated square waffle slab (9), which can be embedded with small cylinders (63). This will end up with the same results as in the entirely prefabricated structure in the fifth embodiment. Under a certain strength requirement, this has lighter weight than the entirely prefabricated one, which had the advantage of easier conjunction.
Using the prefabricated waffle slabs 2-9 in the above embodiments and the accompanying pillars (or columns) (1), the described structure of the waffle slabs for the fab will very well achieve the goals in safety control, fire proof, quake tolerance and fast construction.
