Abstract
The very large span spatial structure consists of several tripods connected through upper and lower straight beams. The tripods are crossed and each tripod has its central column base corresponding to the first and last ends the base of two adjacent tripods; the tops of two adjacent tripods are connected through side straight beam; the lower straight beams connect the bases of the adjacent tripods; and the upper straight beams connect the tops of the adjacent tripods. The very large span spatial structure is firm, compression resistant and shockproof and its arc degree may be regulated via the bases of the tripods.
Description
Technical field
The utility model 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 purpose of this utility model is to solve the problem that prior art exists, but provides 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 placed on the tripod base 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 between the first and last end on relative tripod base between the top of central post of lower inclined beam, relative tripod and the bottom and be fastened with the skew back beam.
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 11A 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.
Claims (2)
1, a kind of this very large span spatial strcture, it is characterized in that, constitute by the tripod group that last straight beam and following straight beam link together by several, tripod dislocation in the said tripod group is placed, the first and last end position correspondence on two tripod bases 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 placed on the tripod base near the central post position, the in addition first and last end on two adjacent tripod bases corresponding with this central post position rides on this time 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.
2, very large span spatial strcture according to claim 1 is characterized in that being fastened with between the first and last end of tripod relative in two groups of adjacent tripod groups between the top of central post of lower inclined beam, relative tripod and the bottom and is fastened with the skew back beam.
