Abstract
Provided is a concrete filled steel tube-grillage composite structure system of a large-span pre-stressed garage board. The concrete filled steel tube-grillage composite structure system comprises a large-span pre-stressed beam slab, concrete filled steel tube arch chord members, support beams, columns, rigid vertical rods arranged between an arch chord tube and a panel surface and capable of bearing pressure and tension and stable connecting rods and is characterized in that the support beams are placed on the columns; the large-span pre-stressed beam slab is placed on the support beams at two ends in a sectional manner; the concrete filled steel tube arch chord members are placed on the columns at two ends or the support beams at the upper parts of the columns in a sectional manner; the vertical rods are arranged between the arch chord tube and the panel surface (a ribbed back); upper parts of two adjacent vertical rods of two adjacent boards at the upper parts are connected or welded by the stable rods; and filling operation is carried out following roof treatment.
Description
Art: building materials field
Background technology:
Large-span prestressed groove-shaped laminated board is big for underground garage span, parking stall is many, attractive in appearance, the duration fast but 1, floor height big, the use in underground garage of the large-span prestressed plate is primarily limited to floor height, the floor height height cost of certainty plate own is high, and it is deep to cut the earth, its earthwork or explosion, steel water proof exterior wall are expensive, and especially subsoil water anti-floating processing cost is high, 2, effective area is little, and relative cost is bigger.16.6 meters of groove type plates such as design load every square metre 53,000 Ns, rib is up to 1.02 meters, plus the supporting part height of backbar at about 0.5 meter, it it is about 1.6 meters, and typically arch without beam such as honeycomb core height is at about 0.6 meter, differ the biggest, and the wide only 1.2 meters of effective areas of plate are the least, if plate is wide at 2.5 meters, rib height need to be at about 1.7 meters, not only the cost of plate own is high far beyond economic rib, outside cannot using, underground garage often digs deep 1 meter of anti-floating handling then increasing water, steel water proof exterior wall expense, earth excavation or blast cost are then at 250-450 unit/m2Left and right, cannot realize undoubtedly, and bending component cannot open big hole and trimming bar concrete is disposed more complicated.
nullSummary of the invention: provide a kind of large-span prestressed garage slab pipe concrete grillage combined structure system to solve the problems referred to above for the problems referred to above present invention: a kind of large-span prestressed garage slab pipe concrete grillage combined structure system，Including Large Span Prestressed Beam plate、Concrete-filled steel tube arch chord member、Backbar、Pillar、Arrange between chord of arch pipe and plate face not only bears pressure but also bear the rigidity montant of pulling force、It is stably connected with bar，It is characterized in that: backbar is placed on pillar，Large-span prestressed garage plate、Vertical or horizontal breaking is placed on beam supported at both ends，Concrete-filled steel tube arch chord member is broken and is placed on the pillar of two ends or on the backbar on pillar top，Arrange between chord of arch pipe and plate face (ribbed back portion) and not only bear pressure but also bear the hinged montant of rigidity of pulling force，The montant top stabiliser bar that two of two adjacent panels in top adjacent is connected or welding，Backfill soil filled out by roofing after processing；Further, described large-span prestressed garage plate includes T plate, single T plate, trough plate, F shape plate；Further, large-span prestressed garage slab pipe concrete grillage combined structure system is characterized in that: top can arrange overlapping layers；Further, described concrete-filled steel tube arch chord member can be substituted by truss and form large-span prestressed garage plate plate girder combined structure system；Further, pulling force is born above large-span prestressed garage plate, in pressure transmission to concrete filled steel tube；Further, plate, arch, pillar, backbar are integrally connected；Further, large-span prestressed garage slab pipe concrete combination structure system, it is characterised in that: between span 4-36 rice, plate hight is between 0.3-3 rice, and plate is wide between 0.5 meter-9 meters, and design load Qd every square without deadweight is between 1.5-15 ton；Further, montant is done with steel pole, steel pipe, concrete filled steel tube bar, reinforcing bar, steel reinforced concrete pole or prestressed reinforced concrete bar, pre-stressed steel pipe concrete bar；Further, plate montant plate having nuclear blast to walk fire fighting truck especially above is strengthened；Further, between end bay plate two chord of arch pipe, montant top connects with stabiliser bar or welding.
Accompanying drawing illustrates: figure is large-span prestressed garage slab pipe concrete grillage combined structure system schematic diagram, and Fig. 1 is side elevational view, and Fig. 2 is birds-eye view, wherein 1 is frame column, and 2 is chord of arch bar, and 3 is montant, 4 is concrete filled steel tube and post junction point, and 5 is large-span prestressed concrete beam slab.
Detailed description of the invention: as shown in the figure, frame column 1 and framework backbar is built by conventional method, chord of arch bar 2 two ends are placed on end frame trestle 1, it is placed on backbar laterally or longitudinally disconnected for large-span prestressed concrete beam slab 5, the hinged montant of rigidity 3 is set between large-span prestressed concrete beam slab 5 and chord of arch bar 2, the montant 3 top stabiliser bar that two of two adjacent panels 5 in top adjacent is connected or welding, and backfill soil filled out by roofing after processing.The power being so subject on large-span prestressed concrete beam slab 5 is delivered on chord of arch bar 2 by montant 3, and chord of arch bar 2 passes on frame column 1, is the formation of a kind of large-span prestressed garage slab pipe concrete grillage combined structure system.
