HIGH STRENGTH MEGA-TRUSS STRUCTURE USING STEEL- CONCRETE SANDWICH BEAM AND FACTORY BUILDING
USING THE SAME
Technical Field
[1] The present invention relates to a high strength mega- truss structure, which is adapted to be effective to the vibration by constructing steel-concrete sandwich beams with the advantage of construction efficiency of a steel structure and the advantage of high strength and high damping capacity of an RC structure by means of the synthetic action of steel member and concrete, as upper and lower floor beams, and disposing web members between the upper and lower floor beams to thereby make the upper and lower floor beams move concurrently, and a factory building accomplished as an anti- vibration building by applying such mega-truss structure to it. Background Art
[2] Factory buildings for the precision high-tech products, such as a semiconductor and an LCD, correspond to an anti- vibration buildings, which is particularly sensitive to the vibration in comparison with other type of buildings. In the case of these structure, in order to minimize the vibrations, it is required for the beam member to have the high strength rather than the ductility. As for the beam developed in consideration of such requirements, there is disclosed a Korean patent application No.2004-73688, entitled with "A steel-concrete sandwich beam".
[3] Meanwhile, it is required for the anti- vibration factory building to be completed within a very short term in order to having the competitive power as a industry of timing, and for a FAB floor to be defined as a space with non-post and long-span so as to make it possible to freely move the equipments and design the production line. In order to satisfy such requirements, it is required to perform the construction of the upper and lower floors at the same time for the very short term construction, and to complement the lower floor of the FAB floor structurally for the formation of the FAB floor with non-post and long-span. Until now, such requirements have been met by constructing a main frame at first and then constructing a PC mid-post at the lower floor of the FAB floor. However, such a method of constructing a PC mid-post is disadvantageous in that it is tiresome because the construction process is performed in a semi-wetting type, and it is difficult to be applied to the structure constructed by the steel-concrete sandwich beam disclosed in Korean patent application No. 2004-73688.
[4] Of course, in order to meet such equirements concurrently, the steel member may be used as a mid-post in place of the PC mid-post, or the steel member may be used as
an inclination member to accomplish the truss structure. Particularly the method of accomplishing the truss structure is preferred in making the upper and lower floors move concurrently and producing the high strength structurally.
[5] According to the conventional truss structure, the upper floor beam may be constructed as a top member and the lower floor beam as a bottom member, and then a web member may be constructed by connecting the upper floor beam and the lower floor beam in a wave shape. In this instance, the web member with a same width as that of a beam may be selected. However, because such a web member also becomes large as the cross section of the beam becomes large, it is advantageous in that the strength improves but disadvantageous in that the construction cost increases due to the increase of the amount of the steel member, the construction efficiency is not favorable due to the increase of lifting weight, and the self- weight of the structure increases due to the increase of the own weight. Disclosure of Invention Technical Solution
[6] Accordingly, the present invention for solving the above problems provides a high strength mega-truss structure using a steel-concrete sandwich beam, comprising:
[7] an upper floor beam constructed by the steel-concrete sandwich beam including a primary lateral shape steel member for defining one side of the beam by disposing the steel member comprised of top and bottom flanges and a web along the longitudinal direction of the beam, a secondary lateral shape steel member for defining other side of the beam by disposing the steel member comprised of top and bottom flanges and a web in parallel with the primary lateral shape steel member so that top flanges are arranged at regular intervals with each other by themselves, and a filled concrete placed between the primary lateral shape steel member and the secondary lateral shape steel member;
[8] a lower floor beam positioned below the upper floor beam and having the same structure as the upper floor beam, and which includes a tertiary lateral shape steel member corresponding to the primary lateral shape steel member of the upper floor beam, a quaternary lateral shape steel member corresponding to the secondary lateral shape steel member of the upper floor beam, and a filled concrete placed between the tertiary lateral shape steel member and the quaternary lateral shape steel member;
[9] a primary web member jointed to a bottom flange of the primary lateral shape member and a top flange of the tertiary lateral shape steel member, and defining a wave form between the primary lateral shape steel member of the upper floor beam and the tertiary lateral shape steel member of the lower floor beam; and

steel member and a top flange of the quaternary lateral shape steel member, and defining a wave form between the secondary lateral shape steel member of the upper floor beam and the quaternary lateral shape steel member of the lower floor beam, the secondary web member being disposed to be spaced apart from the primary web member;
[11] wherein the filled concrete of the upper floor beam is constructed integrally with slab concrete above the upper floor beam, and the filled concrete of the lower floor beam is constructed integrally with slab concrete above the lower floor beam.
[12] Also, the present invention provides a factory building for manufacturing high-tech products such as a semiconductor and an LCD, which is designed to include a FAB floor defined as a space with non-post and long- span, wherein a lower floor of the FAB floor is constructed by the high strength mega-truss structure using steel-concrete sandwich beam.

[17] Hereinafter, the preferred embodiment of the present invention will be described in detail with reference to the appended drawings.
[18] In the present description, FIGs. 1 and 2 are a cross-sectional view and a front view showing an embodiment of the high strength mega-truss structure according to the present invention. The high strength mega-truss structure according to the present invention comprises an upper floor beam 100, a lower floor beam 200, a primary web member 310, and a secondary web member 320, and is technically characterized in that steel-concrete sandwich beams, which is constructed by lateral shape steel members at both sides, are constructed as the upper and lower floor beams, and the primary and secondary web members 310, 320 are disposed doubly between the upper floor and the lower floor beams 100, 200.
[19] In other words, each of the lateral shape steel members, which constitute both sides of the steel-concrete sandwich beam, is provided with a primary web member 310 and a secondary web member 320 separately, so that the construction cost can be reduced
due to the decrease of the amount of the steel member and convenience of the construction due to the decrease of the weight of the web member can be obtained together with producing the same strength as the case of being provided with a web member having a large cross-section.
[20] As shown in FIG. 1, the upper floor beam 100 and the lower floor beam 200 are made of the steel-concrete sandwich beam. The steel-concrete sandwich beam constituting the upper floor beam 100 is constructed by a primary lateral shape steel member 110, a secondary lateral shape steel member 120, and a filled concrete 130. The steel-concrete sandwich beam constituting the lower floor beam 200 is constructed by a tertiary lateral shape steel member 210 corresponding to the primary lateral shape steel member 110 of the upper floor beam, a quaternary lateral shape steel member 220 corresponding to the second lateral shape steel member 120 of the upper floor beam, and a filled concrete 230 placed between the tertiary lateral shape steel member and the quaternary lateral shape steel member.
[21] The upper floor beam 100 is accomplished by the construction that the top flanges
112, 212 are disposed in parallel at regular intervals there-between so that the primary lateral shape steel member 110 and the secondary lateral shape steel member 120 form both sides thereof, and the filled concrete 130 is placed in the space formed between the primary lateral shape steel member 110 and the secondary lateral shape steel member 120 through the space formed by disposing the top flanges 112, 212 separately. In this instance, the filled concrete 130 should be constructed concurrently with the slab concrete Sl above the upper floor beam so that the upper floor beam 100 is integrated into the slab constructed thereon. As a result, the slab S 1 of the upper floor and the upper floor beam 100 become to move integrally. The lower floor beam 200 is accomplished according to the same method as the upper floor beam 100, by constructing both sides thereof with the tertiary lateral shape steel member 210 and the quaternary lateral shape steel member 220.
[22] As for the primary, secondary, tertiary, and quaternary lateral shape steel members
110, 120, 210, and 220 constituting the upper and lower floor beams 100, 200, the steel member comprising the top flanges 112, 122, 212, 222, the bottom flanges 111, 121, 211, 221, and the web members 113, 123, 213, 223 is used, which may be an I- section steel, a C-channel, or an Z-section steel representatively. However, when the conventional I-section steel, the C-channel, or the Z-section steel is used, supporting plates 125, 225 are disposed between the bottom flanges to close the bottom of the beam. Because the bottom flanges 111, 121, 211, 221 may be also disposed at regular intervals there-between if the top flanges 112, 122, 212, 222 are disposed at regualar intervals there-between. In FIG. 1, there is shown an example in which steel plates are used as the supporting plates 125, 225 to construct them suspended between the bottom
flanges.
[23] Also, as shown in FIG. 3, as for the primary, secondary, tertiary, and quaternary lateral shape steel members 110, 120, 210, and 220, any one of the I-section steel, a C- channel, or an Z-section steel, in which the width of the bottom flanges 111, 121, 211, 221 is formed to be wider than that of the top flanges 112, 122, 212, 222, can be used. In this instance, it is not necessary to use the extra supporting plate. Because the top flanges can be justly disposed at regular intervals there-between, when the bottom flanges are disposed to abut against each other by themselves. Furthermore, such the primary, secondary, tertiary, and quaternary lateral shape steel members 110, 120, 210, and 220 have the advantage of securing structural stability because they are effective in transferring the stress between the lateral shape steel members constituting both sides of the beam.
[24] Meanwhile, it is preferable that shear connectors 115, 215 are further jointed to the top flanges 112, 122, 212, 222 of the primary, secondary, tertiary, and quaternary lateral shape steel members to suppress the sliding movement of the slab. In this regard, there is shown an example that stud bolts are used as for the shear connectors 115, 215 in the embodiment of FIG. 1, however, any element except the stud bolt can be used. Although there is not shown in the drawings, it goes without saying that diverse type of shear connectors can be jointed to the inside of the primary, secondary, tertiary, and the quaternary lateral shape steel members to strengthen the integrality of the primary, secondary, tertiary, and quaternary lateral shape steel members 110, 120, 210, 220 and the filled concrete 130, 230.
[25] In addition, the primary and secondary web members 310, 320 are doubly disposed between the upper floor beam 100 and the lower floor beam 200. The primary web member 310 is disposed to be jointed to the bottom flange 111 of the primary lateral shape steel member 110 and the top flange 212 of the tertiary lateral shape steel member 210 to define a wave form between the primary lateral shape steel member 110 of the upper floor beam and the tertiary lateral shape steel member 210 of the lower floor beam. The secondary web member 320 is disposed to be apart from the primary web member 310, and it is jointed to the bottom flange 121 of the secondary lateral shape steel member and the top flange 222 of the quaternary lateral shape steel member to define a wave form between the secondary lateral shape steel member 120 of the upper floor beam and the quaternary lateral shape steel member 220 of the lower floor beam. In this instance, as shown in FIG. 2, it is more preferable in structure to dispose the primary web member 310 and the secondary web member 320 so that their wave forms intersect each other in zigzag shape to the opposite directions. Thus, the upper floor beam and the lower floor beam can be moved integrally as they are connected by the primary and secondary web members 310, 320.
[26] Meanwhile, as shown in FIGs. 1 through 3, vertical stiffners 114, 124, 214, 224 can be further jointed to an outer side of the web members 113, 123, 213, 223 between the top flanges and the bottom flanges of the primary, secondary, tertiary, and quaternary lateral shape steel member on a line identical to the joint portion of the primary and secondary web members 310, 320. The vertical stiffners 114, 124, 214, 224 are operated to facilitate the transference of the stress from the primary and secondary web members 310, 320 to the primary, secondary, tertiary, and quaternary lateral shape steel members 110, 120, 210 and 220, and to prevent the bending of the primary, secondary, tertiary, and quaternary lateral shape steel members concurrently.
[27] FIG. 4 is a conceptual diagram showing the application of the high strength mega- truss structure as described above to the high technology factory building such as a semi-conductor manufacturing factory and a an LCD manufacturing factory.
[28] As the FAB floor, which is formed by a space with non-post and long -span, is required for such factory building, the lower floor of the FAB floor should secure the structural stability as well as the construction efficiency and the space efficiency at the same time. In considering these points, the high strength mega-truss structure is applied to the lower floor of the FAB floor in the present invention.
[29] The high strength mega-truss structure is applied to the factory building as follows.
At first the primary, secondary, tertiary, and quaternary lateral shape steel members 110, 120, 210, and 220 constituting the upper and lower floor beams 100, 200 are disposed to their proper positions. Next, the primary and secondary web members 310, 320 are jointed between the primary, secondary, tertiary, and quaternary lateral shape steel members. And then a matrix, a deck-plate, or a half-PC slab is disposed to construct the slab for the upper and lower floors, and the filled concrete 130, 230 and the slab concrete Sl, S2 are placed simultaneously.
[30] Although the lower floor of the FAB floor constructed as described above is separated in the space due to the disposal of the primary and the secondary web members 310, 320, it can also secure a space for carrying in equipments at the upper and lower portions of the primary and the secondary web members 310, 320, so that it can be designed to be used as a machinery room or an electric room in the factory building. Industrial Applicability
[31] As described above, according to the present invention, it is possible to apply to the anti- vibration building because it produces an advantageous effect to the vibration reduction by constructing steel-concrete sandwich beams with the advantage of high strength and high damping capacity of an RC structure and the advantage of the construction efficiency of a steel structure by means of the synthetic action of the steel
member and concrete, as upper and lower floor beams, and disposing web members between the upper and lower floor beams to thereby make them move concurrently. [32] Also, it is possible to dispose the web members doubly by using the steel-concrete sandwich synthetic beam to thereby make it possible to use less steel member in comparison with the conventional steel-truss having the same strength, so that reduct ion effect of the construction cost can be expected and it is possible to devise the convenience in the construction by using the light-weight members.
