Description

A kind of planar radial retractable Roof Structures with rigid roofing plate
Technical field
The present invention relates to a kind of planar radial retractable Roof Structures with rigid roofing plate.
Background technology
Retractable Roof Structures are a kind of new structures to grow up nearly over half a century, can according to the variation of air and The use demand of building partly or entirely opens and closes roof system.There are two types of stabilizations for the tool that is mainly characterized by of retractable Roof Structures Configuration:Fully closed condition and it is fully deployed working condition.Roof system serviceability limit stage needs to move and possess multiple and different Stress compared with conventional building construction, designs and constructs and is more complicated.Therefore domestic External building is for retractable Roof Structures Application it is extremely limited, and cannot well meet building function demand of the people to retractable Roof Structures.
The content of the invention
The technical problems to be solved by the invention are in view of the deficiency of the prior art, and to provide a kind of vertical Good rigidity, shrinking percentage it is big and it is simple in structure be easy to fold the planar radial retractable Roof Structures with rigid roofing plate.Meet Building pair can open up the various functions requirement of roof structure, also have many advantages, such as to design and easy for construction.
In order to solve the above technical problems, the technical solution adopted by the present invention is:
A kind of planar radial retractable Roof Structures with rigid roofing plate, by lower flat radially retractable roof structure and Top rigid roofing plate composition, it is characterised in that:Planar radial folding house roof by more than two circumferential chain scissor mechanisms and More than two radial direction chain scissor mechanisms composition, circumferential chain scissor mechanism arranged concentric, radial direction chain scissor mechanism is along institute State the radial arrangement for the annulus that circumferential chain scissor mechanism is formed;Circumferential chain scissor mechanism is single by multiple circumferential symmetrical scissors hinges Member is from beginning to end to be circularized;Radial direction chain scissor mechanism is connected to linear end to end by multiple radial symmetric scissors hinge unit;It is described Circumferential symmetrical scissors hinge is hingedly made of the first connecting rod of two equal lengths among bar, and the radial symmetric scissors hinge is by two The second connecting rod of a equal length hingedly forms among bar;Radial direction chain scissor mechanism passes through footpath with circumferential chain scissor mechanism It hingedly realizes and is connected with the first connecting rod end of circumferential symmetrical scissors hinge unit to the second connecting rod end of symmetrical scissors hinge unit, And radial direction chain scissor mechanism, which stretches out outmost turns circumferential direction chain scissor mechanism end and is articulated with only, has vertical rotating freedom The hinged-support of degree;The planar radial retractable Roof Structures are divided on the projection surface by continuous triangle roof boarding connection each other The rigid roofing plate connection unit of unit and quadrangle roof boarding connection unit composition;
Radially chain scissor mechanism is symmetrical for the triangle roof boarding connection unit, the triangle Roof plate element Three vertex include first that two radial direction chain scissor mechanisms at interval and the circumferential chain scissor mechanism of inside are hingedly formed Vertex, the second vertex and radial direction chain scissor mechanism among the first and second vertex and the adjacent circumferential direction of innermost circle The 3rd vertex that the hinge joint of chain scissor mechanism is formed.
Radially chain scissor mechanism is symmetrical for the quadrangle panel connection unit, the quadrangle panel connection unit Four vertex are located on three adjacent radial direction chain scissor mechanisms and are all cut in radial direction chain scissor mechanism and circumferential chain On the hinge joint of formula mechanism;Four vertex of the quadrangle panel connection unit include cutting positioned at three adjacent radial direction chains Two circumferential chain scissors machines of the intermediate radial chain scissor mechanism of formula mechanism and separately one circumferential chain scissor mechanism The 4th vertex and the 5th vertex on the hinge joint of structure and in three adjacent radial direction chain scissor mechanisms both sides footpath To chain scissor mechanism and by the 6th vertex and the 7th vertex on the hinge joint of circumferential chain scissor mechanism separately;
Wherein triangle roof boarding connection unit S, quadrangle roof boarding connection unit is N number of, and X is radial direction chain scissors machine The number of structure, Y are the number of circumferential chain scissor mechanism, then meet
The top rigid roofing plate by be located at the triangular panels connection unit the first rigid plate fold unit and Unit composition is folded positioned at the second rigid plate of the quadrangle panel connection unit;First rigid plate folds unit by two Into an isosceles triangle after the first above rigid plate group is hingedly formed and is unfolded, the first rigid plate of each pair group is firm by two pieces Property plate is along the hinged foldable structure in the high position of the isosceles triangle, two pieces of rigid plates of phase adjacency pair the first rigid plate group Between folding direction on the contrary, the folding direction between adjacent first rigid plate group is opposite;Second rigid plate folds unit The vertical quadrangular plate of linea angulata, each pair second are rigid in a pair after hingedly being formed and be unfolded by four pairs or more of the second rigid plate group Plate group is two pieces of phase adjacency pair the second rigid plate group along the hinged foldable structure in the diagonal position by two pieces of rigid plates Folding direction between rigid plate is on the contrary, the folding direction between adjacent second rigid plate group is opposite.
High equidistant placement of the first rigid plate group along the isosceles triangle;Second rigid plate group is along the quadrangular plate Diagonal equidistant placement.
