Abstract
The present invention relates to a very large span spatial structure which solves the problems that the span of the existing spatial structure is finite and needs the precise calculation of top stress, etc., the existing spatial structure is not easy to reinforce, and compression resistant and shockproof functions are both influenced. The very large span spatial structure is formed by a method that a plurality of tripod sets are connected by upper straight beams and lower straight beams. Tripods in the tripod sets are placed in displacement. The bottom part of a central column of a tripod in the tripod sets is corresponding to the front and the tail ends of the bottom sides of another two tripods adjacent to the tripod, and the top parts of central columns of the two adjacent tripods are connected by a side straight beam. The lower straight beams are arranged at the bottoms of the tripods nearby the central columns, and the front and the tail ends of the bottom sides of another two adjacent tripods corresponding to the central columns are lapped on the lower straight beams. The upper straight beams are fastened between the top parts of central columns of tripods which are opposite in two sets of adjacent tripod sets. The very large span spatial structure has the advantages that the very large span spatial structure can be largely lapped in span and is firm, compression resistant and shockproof; the radian of a lapping structure can be adjusted by the bottom sides of the tripods.
Description
Technical field
The invention belongs to a kind of building unit, particularly a kind of very large span spatial strcture.
Background technology
How the large-span space structure of building trade is made up of rope, bar, film at present.Not only span is limited, also needs many-sided accurate calculating such as prestressing force.Owing to influenced by self gravitation and tensile force, its limited length, and difficult reinforcing, resistance to compression, shockproof function all are subjected to certain influence.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, but provide a kind of overlength span to build and firm, resistance to compression, shockproof very large span spatial strcture.
This very large span spatial strcture is made of by the tripod group that last straight beam and following straight beam link together several, tripod dislocation in the said tripod group is placed, the first and last end position correspondence on the base of two tripods in addition that the central post bottom of a tripod in the tripod group is adjacent, and connect by the side straight beam between the central post top of two adjacent tripods, said straight beam down is connected on the tripod base relative in two groups of adjacent tripod groups near the central post position, and the in addition first and last end of two adjacent tripods corresponding with this central post position rides over down on the straight beam, and the said straight beam of going up is fastened between the central post top of tripod relative in two groups of adjacent tripod groups.
According to above-mentioned very large span spatial strcture, in two groups of adjacent tripod groups, be fastened with lower inclined beam between the first and last end of relative tripod, be fastened with the skew back beam respectively between the central post top of two relative tripods and the bottom.
It is architectural that this very large span spatial strcture can be applied in super-span bridge, hangar, exhibition hall, ancient site, sports palace etc., and its advantage is:
1, can build by super-span, single group build can infinitely prolong, and can infinitely connect between tripod group and the group, can augment span at any time.
2, firm, resistance to compression, shockproof.Structural elasticity after building is strong, and is shockproof.It is firm to connect into large stretch of back, and the damage of single straight beam or tripod can not make total cause to cave in, be easy to repair.Resistance to compression after every bit is stressed, all can be carried out the transmission of power, and pressure is passed to other tripod and tripod group.
3, be not subjected to the influence of tensile force.
4, the radian of building structure can be regulated by the base of tripod.
If 5 use as the roof and can be built into more than two, the base is loaded onto wheel and is installed to change and raise the vault that machine is made opening-closing type.

The specific embodiment
As Fig. 1～shown in Figure 4, this very large span spatial strcture is made of by the tripod group 1 that last straight beam 6 and following straight beam 3 link together several, tripod dislocation in the said tripod group 1 is placed, the base 13A head end of the tripod 13 that the central post 11B bottom of a tripod 11 in the tripod group 1 is adjacent, the base 12A terminal position correspondence of tripod 12, and two adjacent tripods 12,11 and 11,13 central post 12B, 11B and 11B, 13B is near connecting by side straight beam 7 between the position, top, said straight beam 3 down is connected tripod 11 relative in two groups of adjacent tripod groups 1 (12,13) base 11A (12A, 13A) go up near central post 11B (12B, 13B) position, and in addition two adjacent tripod 12 base 12A ends corresponding with this central post 11B position, tripod 13 base 13A head ends ride over down on the straight beam 3, and are fastening therebetween.The said straight beam 6 of going up is fastened between the last close position, top of central post 11B, 12B, 13B of corresponding tripod 11,12,13 in two groups of adjacent tripod groups 1, in two groups of adjacent tripod groups 1, be fastened with lower inclined beam 4 between the first and last end of relative tripod 11,12,13, be fastened with skew back beam 5 respectively between central post 11B, 12B, 13B top and the bottom of relative two tripods 11,12,13.
The angle of the tripod 11,12,13 in this very large span spatial strcture is according to the actual adjustable angle that requires, as shown in phantom in Figure 5, and to adjust the radian of space structures.
As shown in Figure 6, by several tripod groups 1, can be overlapped to form rectangle, square or rounded roof.
Tripod in the above-mentioned very large span spatial strcture and straight beam or cant beam, the tie point between tripod and tripod, straight beam and straight beam or the cant beam can be welding, snap close or other connected mode.
