Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, Space Beam-strut-drag-line steel structures coating described in the present embodiment, comprise several interconnective element of construction, each element of construction mainly comprises some beams 1, four struts 2, two drag-lines 3 and a connected node 4, each beam 1 is crisscross is fixed into flat grid structure, four strut 2 one end are with being fixed on connected node 4, the other end is individually fixed in the beam-beam knot point place in flat grid structure, two drag-lines 3 cross through connected node 4, and drag-line 3 respectively holds the beam-beam knot point place be individually fixed in outside strut 2.
In the present embodiment, the 16 lattice structure unit be made up of beam 1 are provided with two rectangular pyramid structures (as Fig. 1); Wherein, four strut 2 one end are separately fixed at four knot point places of middle part sphere of movements for the elephants frame, and one end is concentrated and is fixed on connected node 4, forms a little rectangular pyramid structure; Drag-line 3 respectively holds four the knot point places be separately fixed on element of construction housing, and middle part crosses through connected node 4, forms a large rectangular pyramid structure be enclosed within outside little rectangular pyramid structure.The integral rigidity of this element of construction is respectively from bending resistance component beam and drag-line two parts, it is a kind of semirigid structure between rigid structures and flexible structure, solve the problem of tension string beam structure Out-of-plane Stability deficiency in prior art, this is simple for structure attractive in appearance, adopts this structure also can simplify installation process.
In the present embodiment, as shown in Figure 2, described connected node 4 comprises joint 41, connect block I 42 and connect block II 43, described joint 41, connect block I 42 and connect the corresponding groove being provided with formation two drag-line holes 44 capable of being combined on block II 43, described joint 41, connect block I 42 together with connecing and being fastened by bolts between block II 43, two drag-line holes 44 are arranged in a crossed manner and stagger up and down and have the distance of 50 ~ 60mm, when drag-line 3 is installed, by connected node 4 three items, after drag-line 3 places in groove, correspondence by a few part snap-fit together, and be fastened by bolts, installation process is simple, be convenient to change drag-line 3.
In the present embodiment, as shown in Figure 3, Figure 4, drag-line 3 is fixed on beam-beam knot point place by otic placode 5, and beam 1 is H profile steel, and otic placode 5 and strut 2 are all fixed on the web of H profile steel; Drag-line 3 is ears bidirectional modulation drag-line, as shown in Figure 5, comprises through the cable body 31 in drag-line hole 44, the anchoring cartridge 32 being fixed on cable body 31 end and ears fork anchor ring 33, is also provided with adjusting screw(rod) 34 between described ears fork anchor ring 33 and anchoring cartridge 32; Ears fork anchor ring 33 is fixed on otic placode 5 by bearing pin 35, and the rate of tension of drag-line 3 regulates by adjusting screw(rod) 34.
The work progress of this structure is as follows:
1. mounting rail successively, during mounting rail, for avoiding distortion excessive, should adopt stent support;
2. at web place welding otic placode, otic placode location needs accurate unwrapping wire, should control the distance between the angle of otic placode and otic placode pin shaft hole center, diagonal angle two;
3. welded with web strut one end, the other end welds with connected node;
4. drag-line be installed and make drag-line tensioning by rotating bidirectional modulation screw rod;
5. jack one-end tension drag-line is used, stretch-draw at twice; Test back absolute altitude, after confirming that absolute altitude is normal, check that weld seam has flawless everywhere, flawless is dismountable support then, carries out subsequent construction.
Fig. 6 is tension string beam structure of the prior art, as can be seen from the figure, when all the other conditions are identical, native system whole structural stability is good, although traditional tension string beam structure has added plane outer support in center, but still there is the possibility of the outer unstability of plane in stretching process, this structural system then solves this problem.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
