In its steel empty stomach net superstructure and the steel grid formula frame, the grid structure is all pressed strip grid cell [bin] and is divided, in the workshop unloading, cut, and drilling, weld forming, all in factory workshop processing, remote transportation does not receive the hindrance of charge station's door opening width, goes everywhere without any hindrance here to transport to the job site to, installs at the scene to form wholly, reaches the industrialization requirement of prefabricated assembly.
Description
Technical field
The invention belongs to construction engineering technical field, relate to a kind of multilamellar (2 layers～4 layers) large span (18m～36m) superstructure
For being similar to the construction of square-shaped planar, particularly to a kind of assembled integral orthogonal spatial Steel Space grid box structure, can
So that prefabrication, on-site consolidation one-shot forming, thus reach industrial requirement.
Background technology
In order to Economization on land promotes Ecological Civilization Construction, within 2014, Ministry of Land and Resources puts into effect " Energy-efficient routing soil
Regulation " (No. 61 files) large span is public and industrial building, it is desirable to develop to multilayer large-span, and make corresponding regulation.Right
For steel construction, using traditional steel-frame structure, not only stress is unreasonable, and steel using amount is big, and floor height is the biggest, if plane is 30m
× 30m=900m2, multilamellar (3 layers) sports building, use steel-frame structure to arrange as shown in Figure 1, Vierendeel girder KJ-1 is along Y-direction
Arrange, beam section H2100 × 500 × 16 × 28, not only big (the 120kg/m of steel using amount2Left and right), superstructure thickness reaches 2.5m (pipeline
Under drop in beam), and stress unreasonable (plane force system), due to single span multilayer large-span, its anti-side rigidity is difficult to meet regulatory requirements
(gable framework brace to be increased).In view of the foregoing, using new structural systen as shown in Figure 2, i.e. " assembled integral is just
Hand over and just putting steel space lattice box structure on an empty stomach ", i.e. laterally the empty stomach network of superstructure is divided into A unit 15, unit B 5
Individual, C cell 3, D unit 1；Its vertical grid type framework also blocking simultaneously, as it is shown on figure 3, these grid type unit are equal
Processing in workshop blanking, welding forms grid cell, such as the A type grid cell of Fig. 2, as shown in fig. 4 a, and its plane 7.5m ×
5m=37.5m2, highly h=1.2m (Fig. 4 b), the grid cell that these workshops make, construction site is transported in entrucking to be passed through
Carrying out assembly, on the way charge station, exit all has height and width control system, and Fig. 5 is A unit section structure, and its minimum widith is 2a,
A is size of mesh opening, generally a=(2m～2.8m) scope, and exit width minimum is greater than (4m～5.6m), and otherwise passing through is subject to
Resistance.Only the upper and lower chord member encorbelmented in Fig. 5 width both sides is not welded in workshop for this, transport repair welding again behind job site to
Form the unit shown in Fig. 5, then assemble.Also there is identical problem in grid type wall stand.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is an object of the invention to provide a kind of assembled integral orthogonal spatial
Steel Space grid box structure, for and new structural systen of industrial building public for multilayer large-span, it is possible to resolve workshop
The grid cell ultra-wide made, exit is impassable, and after causing installation unit to split, secondary welding is that unit is overall the most at the scene
The problem carrying out installing.
To achieve these goals, the technical solution used in the present invention is:
A kind of assembled integral orthogonal spatial Steel Space grid box structure, it is adaptable under multilayer large-span, superstructure is long limit
Be less than the system of the approximating square plane of 1.5 with the ratio of span, multilayer large-span refers to 2 layers～4 layers, height overall 18m～36m.
In its steel grid superstructure on an empty stomach and steel mesh lattice frame, network all by strip grid dividing elements, in workshop blanking, is cut
Cutting, boring, welding fabrication, all process at factory floor, long distance transportation is not hindered by charge station's door opening width, current nothing
Resistance transports job site to, installs at the scene and forms entirety, reaches the industrial requirement of prefabrication and assembly construction.
Its length of described strip grid cell is to size L1=na, its short size L2=a, wherein, n is positive integer, and a is bar
Mesh width in the width of shape grid cell, namely steel lattice box structure, a=2m～2.8m.
Described strip grid cell, in the longitudinal direction, has the steel one of four a length of na, puts in double-deck two arrangements,
In the direction of the width, having the steel two of a length of na of 2n root, it is equally spaced with a for spacing between two row's steel one at the middle and upper levels
N root, is equally spaced n root with a for spacing between lower floor two row's steel one, in the height direction, has 2n root steel three, Qi Zhongqian
It is equally spaced n root with a for spacing between row's two-layer steel one, between heel row two-layer steel one, is equally spaced n with a for spacing
Root, every 2 steel two and 2 steel three connect one rectangle of composition, altogether n rectangle, the rectangle at edge and steel one
Respective end between distance be a/2.
The total-grid unit of structural system and upper and lower string component in bulk all in shop-fabricated, if steel mesh lattice frame by
Dry strip grid cell and some H steel loose mails composition.After scene transported to by each component, steel lattice framework bar element is first installed, then
It is connected two-by-two with machined H steel, after forming ground floor grid wall stand entirety, then superstructure strip grid cell on an empty stomach is installed, and
By location-plate between strip grid cell and unit, the upper and lower string T-steel loose mail of machined for workshop molding etc. is fierce
Connect, make structure form orthogonal spatial Steel Space grid box structure overall.
Orthogonal spatial space lattice box structure has excellent mechanical property, and steel using amount is low, but Structure Network is formatted on an empty stomach
After change, node amount increases considerably, and produces by batch in workshop, compared with prior art, and the whole steel structure work amount of the present invention, i.e.
The blanking processing of component, boring and strip grid molding all complete in workshop, and work on the spot amount is greatly reduced, and reduce engineering and become
This.
