Description
?
Technical field
The present invention relates to large public building structural system, specifically is a kind of assembled integral multilayer large-span bidirectional multispan spatial steel grid box structure building.
Background technology
For a long time, public building such as athletic training shop, exhibition hall, large-scale public place of entertainment etc., its minor face span major part is between 30m～42m, and the overwhelming majority is the single of light steel roof system, and this is totally unfavorable to practicing thrift the soil.Reach and work as large public building
lDuring=32m～42m; Adopt conventional prestressed concrete frame structure; Like the garage on T2 airport, capital, will cause " fat beams and columns " phenomenon, also there is the problem that concrete in-situ casting construction speed is slow, the construction civilization degree is difficult to improve simultaneously; Finally cause cost to increase the requirement that does not reach " energy-saving and emission-reduction and low-carbon economy ".
Chinese patent ZL200610200188.X discloses a kind of U shaped steel reinforced concrete combined hollow sandwich slab building cover structure; The grid moulding of its empty stomach and quadrature; Promptly having solved in the Room horizontal tube coil holder such as air-conditioning establishes; Solved the indoor furred ceiling moulding of finishing of the large-scale hall again, but its construction still be unable to do without the cast-in-situ concrete operation, dead load is still bigger than normal simultaneously.
Therefore, make large public building accomplish multilayer multispan and large span, adopt existing concrete and steel framed structure, be difficult to reach good techno-economic, also be difficult to reach the requirement of the function of use of this type of public building requirement large span and large space.
Summary of the invention
The present invention be intended to solve exist when adopting conventional frame construction to build public building because of fat beams and columns concrete that causes and the drawback that rolled steel dosage is big, cost is high, and provide a kind of job site not have the welding operation, construction speed assembled integral multilayer large-span bidirectional multispan spatial steel grid box structure fast, that the construction civilization degree is high, steel using amount can reduce is significantly built.
The technical scheme that the present invention solves its technical problem employing is:
A kind of assembled integral multilayer large-span bidirectional multispan spatial steel grid box structure building; Said each layer of building ground steel structure frame is configured to matrix pattern by central cross steel grid wall frame and individual layer steel mesh form exterior wall all around thereof; Individual layer steel mesh form exterior wall frame around said central cross steel grid wall frame and its by high-strength bolt be connected to form not only divide but also close, four large tracts of land halls of one each other; Said each hall is connected with steel open-spandrel sandwich board building cover structure through high-strength bolt on it, forms single spatial steel grid box structure; Said central cross steel grid wall frame and said individual layer steel mesh form exterior wall frame and said steel open-spandrel sandwich board superstructure frame; Be formed by connecting at the construction field (site) through high-strength bolt by small-sized steel structure assembling unit, said small-sized steel structure assembling unit is made in advance by factory and is transported to the job site again; Said every layer of single spatial steel grid box structure layer upon layer is upwards superimposed; Form the single Tong body of superposed type box structure; Said four the single Tong body of multilayer build-up formula box structures are connected with each other at the superstructure place, form assembled integral multilayer large-span bidirectional multispan spatial steel grid boxlike Tong body bundle.
Further; Constitute the small-sized steel structure assembling unit of said central cross steel grid wall frame and said individual layer steel mesh form exterior wall frame; The horizontal H shaped steel that is connected on this vertical H shaped steel by vertical H shaped steel and two root beads in the middle of being positioned at constitutes, and said vertical H shaped steel is provided with the high-strength bolt connecting hole with the horizontal both ends of H shaped steel.
The small-sized steel structure assembling unit that constitutes said steel open-spandrel sandwich board building cover structure is the diesis structure; Upper strata cross-shaped steel member and lower floor's cross-shaped steel member of this diesis assembly unit unit are welded by intermediate connector, and this upper strata cross-shaped steel member and lower floor cross-shaped steel member both ends are provided with the high-strength bolt connecting hole.
The DQ that said central cross steel grid wall frame and said individual layer steel mesh form exterior wall frame are inlayed through its two sides reaches power lightweight lath and constitutes body of wall.
Compared with prior art; Outstanding effect of the present invention is: adopt cassette space steel lattice structure, each assembly unit unit of its superstructure all processes at factory floor, and carries out weld job; Each assembly unit unit deadweight is controlled at W≤500kg; And traffic regulation requirement when guaranteeing transportation, there is not the welding operation at the construction field (site), eliminate the disaster hidden-trouble that the large-scale steel structure engineering site is constructed fully; Than the large public building of traditional steel framed structure, its steel work cost floats downward 15%～20%, and its construction speed can shorten 1/3 at least, and its construction civilization degree also improves significantly, and anti-side rigidity also increases substantially.
