Abstract
The utility model discloses an installation structure of a dragline gas-film building cave mouth, comprising an outer film, a plurality of first draglines and a basis connection piece, wherein the end of the first dragline is hinged on the basis connection piece, the outer film is arranged below the first dragline, more than one cave mouth is opened on the outer film, more than one first dragline encircles the cave mouth by a switchover plate. The first draglines encircle the cave mouth by the switchover plate, the force which should be born by the film near to the cave mouth is transferred to the first dragline, the force is transferred to the other draglines by the switchover plate and finally to the basis connection piece. The connection direction of the first draglines is changed directly by the switchover plate on the position in need of the opening, the force transfer direction is changed, the stress on the cave mouth is transferred to the first dragline and the stress condition on the cave mouth is improved.
Description
Technical field
The utility model relates to a kind of building structure, relates in particular to the mounting structure of a kind of drag-line air film building, mainly be through to the improvement of drag-line connected mode to improve the stressing conditions at place, hole.
Background technology
The air film structure begins to occur in the sixties in last century as new building types in the world, its have make simple and easy, quick for installation, energy-conservation, be easy to use and advantages such as structural safety, thereby receive extensive use all over the world.Said air film structure elementary cell comprises film and drag-line, and its weight is a thirtieth of traditional architecture.And the air film structure can fundamentally overcome traditional structure in the difficulty that large span (do not have support) is architectural to be run into when realizing, can create huge unscreened visible space.Practical in order to satisfy, said air film structure is typically provided with more than one hole.Random the hole is set causes stress to be concentrated, and long stress is concentrated and can be caused structural failure under the effect of wind load and snow load, even cause whole destruction.But prior art does not well solve this technical problem, can only in the time of design, fully take into account the structure stress variation that opening causes, proposes higher requirement for design and construction, therefore, further improved needs is arranged.
The utility model content
The technical problem that the utility model will solve is to provide the syndeton at a kind of drag-line air film building hole, can change the force-bearing situation at place, hole, reduces the design difficulty of drag-line air film building, improves whole reliability.
For solving the problems of the technologies described above, the utility model adopts following technical proposals:
The mounting structure at a kind of drag-line air film building hole; Comprise outer membrane, some first drag-lines and basic connector; The termination of said first drag-line is hinged on the basic connector; Said outer membrane is arranged on first drag-line below, and has more than one hole, and the above first drag-line is enclosed in around the hole through reversing plate.
In the utility model, said first drag-line is enclosed in around the hole through reversing plate, should work as near the power that film bore the hole and transfer on first drag-line, and this drag-line is passed to other drag-lines through reversing plate with power and finally is delivered on the basic connector.Directly change the closure of first drag-line at the position that needs opening, change the power transmission direction,, improved place, hole stressing conditions Stress Transfer to the first drag-line at place, hole with reversing plate.
Be preferable over: also comprise the supplement film and second drag-line, said supplement film is connected on the outer membrane, and be arranged on the hole outside and and nearest first drag-line in this hole between, said second drag-line is set in the supplement film, two ends are connected on the basic connector.Through supplement film, the stressed of said outer membrane is delivered on second drag-line, and this second drag-line power the most at last is passed on the basic connector.This structure has further been improved stressed distribution around the hole, has strengthened the overall performance of drag-line air film building.
Be preferable over: said second drag-line comprises drag-line body, bar shaped connector, threaded rod, and said drag-line body is connected on the threaded rod, and said bar shaped connector end is provided with screwed hole, and said threaded rod screws in screwed hole.This structure can be regulated the length of second drag-line, can adapt to the hole of different sizes and the drag-line pulling force had the occasion of demands of different.
The beneficial effect of the utility model is: said first drag-line has been eliminated the stress distribution around the hole, makes the security performance of drag-line air film building not receive the influence at hole, has reduced design difficulty and security performance; Said second drag-line acts on the outer membrane through supplement film, makes hole outer membrane on every side stressed more even through the adjusting to the second drag-line length.
Description of drawings
Fig. 1 is the overall diagram of the syndeton at the described drag-line air film building of the utility model hole;
Fig. 2 is the partial view of Fig. 1;
Fig. 3 is the stress distribution sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing to said drag-line gas
[0012]The syndeton at a kind of drag-line air film building hole of the utility model comprises outer membrane 1, some first drag-lines 2 and ground connector 5, and the termination of said drag-line is hinged on the ground connector, has more than one hole 3 on the said outer membrane.Article one, the above first drag-line is enclosed in around the hole through reversing plate 4.And this syndeton also comprises the supplement film 6 and second drag-line 7; Said supplement film is connected on the outer membrane; And be arranged on the hole outside and and nearest first drag-line in this hole between, said second drag-line is set in the supplement film, two ends are connected on the ground connector.
In the utility model, be to realize switching-over to the requirement of said reversing plate 4, change direction to guarantee that first drag-line 2 has under the situation of enough tension force, and realize predetermined space structures.Therefore the structure to this reversing plate has no particular limits, and can adopt the connector that is provided with a plurality of articulated sections, and said articulated section is used for connecting different drag-lines.And the utility model has certain tensile strength requirement to said reversing plate.
According to Fig. 2, said second drag-line 7 comprises drag-line body, bar shaped connector 71, threaded rod 72, and said drag-line body is connected on the threaded rod 72, and said bar shaped connector 71 ends are provided with screwed hole, and said threaded rod 72 screws in screwed hole.Through the mechanical self-latching effect of screw thread, the relative energy of rotation of threaded rod and bar shaped connector produces axial displacement, but axially loaded can not cause relative rotation.Therefore, can adjust the length of second drag-line to the demand of the second drag-line tension force and the actual size at hole, and the tension force that needn't worry second drag-line causes and endwisely slips according to structure itself.
Fig. 3 has shown near the force analysis of the outer membrane in said hole, and wherein the arrow along first drag-line and second drag-line is the distributed force that outer membrane receives.Said first drag-line and second drag-line receive the effect of the distributed load on the outer membrane 1, wind load that this outer membrane receives and snow load can be well along drag-line with turn to rope to hand on, reduced stress and concentrated.
The above is merely the specific embodiment of the utility model.But the utility model protection domain is not limited thereto.Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement; All should be encompassed within the protection domain of the utility model, therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
