Abstract

The invention relates to a super high-rise large-span large-area prefabricated integrated steel mesh box-type bundled tube and bundled tube-in-tube structure and a manufacturing method, in particular to a high-rise (100 m<H</=1000 m) large-area prefabricated integrated spatial steel grid box-type structure, having a non-column area A1 of each unit: A1=(400 m<2>-1296 m<2>) and a central independent column or tube area A2 of each unit in each floor: A2=4A1=(1600 m<2>-5184 m<2>) and a large span L1: L1=(20 m-36 m). In figures, around a mounting unit (1600 m<2>-5184 m<2>) of the type of super high-rise area prefabricated integrated spatial box-type structure, firefighting, traffic and fire-fighting area are provided, a super high-rise (66 floored to 120 floored) spatial steel grid box-type structure having a floor height of 3.6 m can be constructed and a building area can be up to 105600 m<2>-622000 m<2>; a building area (133 floored to 240 floored) can be built (up to 851200 m<2>-4977000 m<2>) by a combination of four in the figure on the right; a super high-rise (200 floored to 360 floored) super-large area (2880000 m<2>-16800000 m<2>) can be built by a combination of nine, that is to say a design of a single building for a city is truly formed.

Description

Tong structure and preparation method in Super High large span large area assembled integral steel lattice boxlike bunchy Tong and bunchy Tong

The present invention relates to a kind of assembled integral Steel Space grid box structure unit, adopt these unit (4 or 9) to form every layer of large area, large span Super High new spatial steel lattice boxlike " in Tong Tong " and " in bunchy Tong Tong " structure.

Background technology

Along with urban architecture high speed development, in order to Economization on land promotes urban ecology civilization, building is to large area, high-rise and super highrise building develops, but architectural structure system still rests on conventional framework, frame one Tong and " in Tong Tong " structural system, as its post net spacing of this type of conventional structure system between (6m ~ 12m), and require restriction by " having wall to have beam ", therefore do to divide room less than large space Multifunctional flexible, limit to its multifunctional application, also do less than large span, as certain layer in the middle of building will be done to perform hall, basketball, the application such as volleyball court, also can not realize, thus restrict the application of its multifunctional comprehensive, conventional Vierendeel girder accounts for floor certain altitude, during as L=12m, i section steel beam adopts H1000 × 400 × 10 × 18, the equipment such as air-conditioner pipe account for highly (500 ~ 600), superstructure thickness accounts for floor height more than 1/4, even if floor typical floor area is done very large, because limiting by post net, also difficulty accomplishes integrated application, from domestic and international built super highrise building analysis, every super highrise building area is generally between more than ten ten thousand square metres to more than 30 ten thousand square metres, can not apply by multifunctional comprehensive again in every layer of architectural plane, therefore existing conventional structure system is adopted, can not realize a building reaches millions of to more than ten million square metre, do not reach a building, namely be one little, the imagination in medium-sized city.

Summary of the invention

The object of the invention is the blocking of assembled integral Steel Space grid box structure, as Fig. 1, elementary cell shown in Fig. 2, the transversary of unit is assembled integral Steel Space grid open-spandrel sandwich board (Fig. 3), its periphery vertical structure is also assembled integral steel mesh form wall stand (Fig. 4), its unit centre is established assembling quadrate steel pipe column (Fig. 1) or is arranged steel and reinforced concrete stairs and elevator, the every one deck boxlike unit of piping shaft (Fig. 2), it is shaped to the grid type box that horizontal and vertical grid forms, as shown in Figure 5, its laterally on an empty stomach grid superstructure with grid type steel wall stand in the orthogonal connection in floor place (Fig. 6), this type of grid type boxlike elementary cell (Fig. 5) layer upon layer upwards superposes, namely Steel Space grid boxlike high-rise structural system is formed, be referred to as Super High grid type list Tong structure, as shown in Figure 7.Single Tong structural plan peripheral size L shown in Fig. 1 and Fig. 7 ₁=20m, 25m, 30m, 36m, then L ₂(width B)=40m, 50m, 60m, 72m, each layer of area A ₁be respectively 1600m ², 2500m ², 3600m ²and 5184m ², the ratio of the height (H) wide (B) of high-rise grid Tong structure, during H/B=5, i.e. B=L ₂when=40m, 50m, 60m, 72m, single space lattice Tong structure height can reach H=200m, 250m, 300m, 360m, by average floor height h=4.2m, this single space lattice Tong can build-up layers number be respectively n=47 layer, 59 layers, 71 layers, 85 layers, by peripheral size L ₂=72m calculates, and building area reaches 85 × 5184=440640m ², this element four is combined, during H/B=5, H=5 × 144m=720m, its number of plies n=720m/4.2m=171 layer, building area A=171 × 20736m ²=3545856m ²=354.58 ten thousand m ²(Fig. 9).

When the central authorities of space lattice box structure arrange fire ladder, when elevator and hoistway, central part post replaces (Fig. 2) by Tong body structure and is referred to as assembled integral Steel Space grid boxlike II type unit, as Fig. 2, shown in 8, its centre Tong body structure replaces steel column, i.e. boxlike II type block construction system, be Tong structure (Fig. 2 and Fig. 8) in Tong by single Tong structural change, while its anti-side rigidity increases substantially, due to by fire-fighting, elevators etc. are arranged at unit central authorities, both the requirement of large area building function had been met in each cellar area, building area several times can be made again to increase.As 4 unit combination (L of Fig. 9 ₁=30m, L ₂=60m, 2 × L ₂=120m), height overall H=600m can be built.Number of plies n=142 layer, building area 204.48 ten thousand m ², in this building, account for area 20m per capita ²calculate, this building can hold urban population 10.22 ten thousand people, uses this element (L equally ₁=36m, L ₂=72m) expand 9 times, as shown in Figure 10, Zhou Bianchang 216m, every layer of building area 216m × 216m=46656m ², calculate by depth-width ratio H/B=5, the building of this nine unit combination, building height overall H=5 × 216m=1080m, still presses floor height h=4.2m and calculates, can build-up layers number n=1080/4.2=257 layer, and this gross floor area reaches 11,990,000 m ², still by accounting for usable floor area 20m per capita ²calculate, this building population capacity 59.95 ten thousand population.On the soil of building area only 87.5 mu (containing traffic, greening, fire-fighting area), account for soil 0.097m per capita ².Namely reach a building is a small and medium cities requirement.The building city in this type of future, still be unable to do without sunlight, air, water, electricity, greening, and space lattice box structure, at every layer of 46656m ²2.769m × 2.769m=7.7m is had in area ²square net 5184 (40,000 m ²), and the every one deck of superstructure is on an empty stomach (Fig. 3), and the water of building, warm, electric facility all can be arranged on an empty stomach, thus make a megaplex form a medium and small city.
