Description
Technical field
The present invention relates to a kind of novel dome structure, the stiffness-supported dome structure that particularly a kind of building field is used.
Background technology
Rapid economic development makes people also growing for the demand of large space, this is promoting the development of space structures undoubtedly, simultaneously also space structures is proposed higher requirement: span is bigger, the space is more penetrating, profile is more various, construction more convenient and quicker and safety economy more.Produced large quantities of Large Span Prestressed space structures under the promotion of this demand: prestressed net shell structure, a beam string structure, string prop up dome, rope dome or the like.These form of structure all have pluses and minuses separately, simply list these several structures main not enough point separately below:
(1) the prestressed net shell structure can produce bigger horizontal thrust at the bearing place, needs a powerful braced structures and could guarantee safety, can make bearing very heavy like this, and waste material.
(2) though a beam string structure is a self equilibrium systems, and the bearing place does not have very big horizontal thrust, girder steel that winds up or steel truss are subjected to the press-bending effect, do not give full play to the strength of materials, and the more permeability of node is poor.
(3) the suspended-dome structure upper strata is confined to single-layer lattice shell, and it is very sensitive to the asymmetric arrangement of load, and unstability takes place easily.
(4) though cable dome structure can remedy above-mentioned several deficiency, its location work progress is comparatively complicated, and when stretching rope, there is frictional force in cable support node, makes strut depart from the equilbrium position, medio-lateral instability.
Summary of the invention
The object of the invention has been to overcome the above-mentioned defective of existing structure, proposed a kind of stiffness-supported dome structure, this structural-load-carrying capacity is strong, stability is high, span is big, the stretching process simple and fast, reduces difficulty of construction greatly, rod member uniform specification, node are succinct, applied widely.
In order to achieve the above object, the present invention has adopted following technical scheme:
A kind of stiffness-supported dome structure, it is characterized in that: described dome structure is upper flexible and lower rigid rope dome, comprise upper and lower two parts, the upper strata is the Spatial Cable web frame, comprise radially drag-line and oblique drag-line, lower floor is the braced structures system that hoop pull bar, vertical strut and diagonal member are formed, and these two parts are connected to form the stress loop at periphery and outer shroud pressurized rigidity ring beam; Each rod member of superstructure is flexible drag-line, and lower floor's all rod members of supporting construction system are push-and-pull rod; Wherein, radially between the drag-line or radially drag-line and the oblique drag-line node that constitutes upper strata rope web frame is connected, vertical strut is that stiffening member is born pressure, vertical strut upper end is connected with the node of upper strata rope web frame, and the lower end is connected with the node of lower layer support structural system hoop pull bar and lower floor's diagonal member.
Described stiffness-supported dome structure, the upper strata radially angle of cut of drag-line 6 and vertical strut 2 are acute angle.
Described stiffness-supported dome structure, upper strata Spatial Cable web frame are gilled rings shape grid or sharp dimension type grid or Kai Weite type grid.
Described stiffness-supported dome structure, the flat shape of upper strata Spatial Cable web frame are circle or ellipse or polygon.
Described stiffness-supported dome structure, the upper strata of dome have radially drag-line of six roads, and dome is divided into six parts.
Described stiffness-supported dome structure is characterized in that: the upper end of vertical strut is connected with upper strata rope net node, and upper strata radially rope is passed this node and is slidingly connected with vertical strut formation.
The length of vertical strut is influence in lower floor's diagonal member vertically and the main member of horizontal direction component size, if other conditions are the same, the long more then vertical force component of strut is big more, otherwise then horizontal component is big more, so in the middle of practical application, should calculate the length of determining strut according to the requirement of fringe conditions and the actual suffered vertical load of structure, and guarantee strut 2 and upper strata radially drag-line 6 angles be acute angle, stressed so more reasonable.
Because lower floor's supporting construction all is made up of push-and-pull rod, when assembling, is convenient to locate all nodes, and has increased the rigidity of structure.The oblique drag-line on the oblique drawbar of lower floor and upper strata makes the total space-load, thereby has improved the resistance to overturning of system.
Stiffness-supported dome structure of the present invention, can by the stretch-draw upper strata radially rope apply prestressing force.The upper strata is the various rope net of shape, and roofing can be laid the rigidity sheet material of flexible materials such as film or lightweight, and the total grid is less, and permeability is good, can satisfy the requirement of architect to moulding and permeability.
Stiffness-supported dome structure of the present invention has simple structure, and power transmission is clearly reasonable, the material novelty, and uniform specification, characteristics such as each is high to stability, and work progress is convenient and swift can be given full play to the intensity of material, reduction of erection time.
