Description
Technical field
The present invention relates to a kind of dome that building field is used, be specially rope bar string and prop up dome.
Background technology
Along with the development of prestressed steel structure, large quantities of new structure systems have been emerged, in recent years as rope dome and suspended-dome structure.The rope dome has simple structure, and system is slim and graceful, and most members are characteristics such as tensional element; It is rope dome and single-layer lattice shell to be combined and the new construction that forms that string props up dome, has increased roofing rigidity, reduces difficulty of construction.But these two kinds of structural systems also have the following disadvantages respectively:
(1) cable dome structure is two-layer up and down is flexible system, and the rod member except that strut all can not be born pressure, makes that the difficulty of construction of rope dome is very big, though emerge for many years, the practical structures of building up so far seldom.
(2) for guaranteeing that all ropes of cable dome structure all are in tension state, must improve the prestressing force magnitude, make the stress of depression bar and side ring beam etc. increase, so very firm bearing must be set or arrange huge ring beam at the bearing place, increased the weight of the braced structures burden, waste material.
(3) because the most of rod member of rope dome is the rope of tension, make that the cable dome structure integral rigidity is little, under load action distortion bigger, roofing materials is generally the membrane structure of lightweight etc.
(4) most rod member pressurizeds in the single-layer lattice shell of suspended-dome structure upper strata are unfavorable for local stability outside the plane of stable and upper strata single-layer lattice shell outside the plane of compressed member.
(5) string props up dome upper strata single-layer lattice shell internal force by lower floor's cable wire and the passive generation of person's external load effect, can not the oneself adjust internal force, makes the most of passive pressurized of upper strata single-layer lattice shell hoop rod member, can not the oneself adjust to reduce pressure.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of rope bar suspended-dome structure, this structure combines the advantage that rope dome chord props up dome, stressed succinct, depression bar is few, the stress system that himself forms sealing reduces or eliminates bearing and side ring beam action, and stable and bearing capacity height has been saved material greatly.
In order to achieve the above object, the present invention has adopted following technical scheme: comprise two parts up and down, the upper strata is made up of center pressure ring 1, last radial bars 2, last hoop rope 3 and side ring beam 7, last radial bars 2 is connected with center pressure ring 1 in the dome center, be connected with side ring beam 7 at periphery, middle and last hoop rope 3 is connected, and the upper strata is grid-shaped and arranges.Lower floor is by radially rope 5, following hoop rope 6 and strut 4 are formed down, the upper end of strut 4 is connected with upper layer node, the lower end is connected with lower level node, radially 4 times end nodes of rope 5 one ends and strut are connected down, the other end is connected with the dome upper layer node, following hoop rope 6 is connected with the following end node of following radially rope 5 and strut 4 along the hoop closed arrangement; Two-layer up and down in the 7 places junction of side ring beam together.Length by hoop rope 6 under the stretch-draw or following radially rope 5 or adjustment strut 4 applies prestressing force in structure, and can or loosen by stretch-draw and go up the internal force that hoop rope 3 is adjusted members.
The grid configuration that described upper strata center pressure ring 1, last radial bars 2, last hoop rope 3 and side ring beam 7 connect into is a gilled rings shape.
Described following radially rope 5 single radially layouts, the one end is connected with the lower end of strut 4, and the other end is connected with upper layer node.
The grid configuration that described upper strata center pressure ring 1, last radial bars 2, last hoop rope 3 and side ring beam 7 connect into is that connection is square.
Described down radially rope 5 double joints be crossed as " V " type and arrange, it intersects end and is connected with the lower end of strut 4, other two ends respectively with the different nodes connections on upper strata.
The length of described strut 4 should guarantee down that the rope radially 5 and the angle of cut of strut 4 are acute angle.
The outer contour shape of described superstructure can be circle or ellipse or polygon.
Described upward hoop rope 3, following radially rope 5, following hoop rope 6 can be flexible wire ropes, steel hinge line, cable etc. or reinforcing pull rod.
The described radial bars 2 that goes up can be that circle or square steel pipe also can be various shaped steel etc. for the rigid rod that bears pressure can be arranged.
Described down radially rope 5 can singlely radially arrange, also can the double joint arranged crosswise.
Because this rope bar string all rigid rod pressurizeds, all rods tensions of propping up dome, make its stressed succinct, calculation Design is very convenient.In addition, the upper strata radially internal force of depression bar is very approaching, so can adopt the rod member of unified specification, processing and manufacturing is very convenient.
Because under the situation of not arranging the side ring beam, this dome also can form force-closed system, so, under normal load action, can eliminate horizontal applied force to the edge braced structures, do not need to arrange huge ring beam or strengthen bearing, reduced the material consumption of braced structures, reduced cost.
Because the last radial bars that can bear pressure has been arranged on the upper strata that rope bar string of the present invention props up dome, and roofing rigidity is significantly improved, and is applied widely so roofing can be used the also available flexible die material of rigidity light plate, and can cross over bigger span.
Because compression member of the present invention is few, tension member is many, and is strand spiral rope, has given full play to the strength of materials, so that it props up dome from the anharmonic ratio string is lighter, it is bigger to cross over span.Superstructure of the present invention radially Moment at End is very little, and can rigidly connect between the last radial bars also can be hinged.When adopting hinged joint, can form tension integral structure, greatly facilitate construction.
Because the hoop rope of going up of the present invention can be strained also and can loosen, so can or loosen and go up the hoop rope by tension, the pressure of radial bars in the adjustment makes its force value littler, more even, thereby improves the stability and the ultimate bearing capacity of total.Obtained reducing owing to go up the pressure of radial bars on the one hand, the last hoop rope that links to each other with last radial bars is a pulling force on the other hand, has strengthened the effect of contraction to the node location on upper strata like this, thereby the depression bar component stability that links to each other with this node is improved.
