Abstract
The invention provides a kind of more Pin space trusses transformational structures, including four truss and four pillars, four truss is end to end to enclose a square body, and four pillar is connected to four right angles of the square body；The truss winds up including one, a lower edge and a plurality of posts；Described wind up be arranged in parallel with lower edge, and a plurality of posts are parallel and interval is located at and winded up between lower edge, and the top of the post is stretched out and winded up.The present invention can improve bending resistance and the shear resistance of beam well, have the advantages of section is small, and deadweight is lighter.
Description
Technical field
Present invention relates particularly to a kind of more Pin space trusses transformational structures.
Background technology
Modern high-rise building also increasingly payes attention to the embodiment of building individuation in addition to the requirement for meeting functional diversities.
Because various complex shapes largely occur, the post net standard width of a room in an old-style house and structure Lateral Resistant System form of upper and lower floor are frequently necessary to change,
In order to ensure effective transmission of structure stress, the application of conversion layer is with regard to more and more common.As modern high-rise building is to multi-functional
With comprehensive purposes development, the skyscraper with transferred floor design constantly increases, according to statistics, in the skyscraper more than 80%
There is conversion layer structure.More commonly used conversion layer structure has：Change girder construction, conversion harden structure.
In several conventional transition forms, beam-type transition layer is most widely used at present.Usually in conversion layer flooring
Armored concrete conversion beam, prestressed reinforced concrete conversion beam are set, to support superstructure.To adapt to the huge lotus in top
Carrying needs, and the sectional dimension of beam is general all larger and directly proportional to the number of plies of support and span.Large scale section, heavy reinforcement,
Cause converted deep beam mass concentration, rigidity is excessive, it is easy to form the phenomenon of " the weak post of brutal ", it is necessary to substantial amounts of construction material and
It is unfavorable to the antidetonation of structure；How much another aspect heavy in section conversion beam can influence the use space of this layer, to ventilation, daylighting not
Profit, obvious stress concentration phenomenon can be produced if opening holes.Thick Plate Transfer Story, even if because profile is simple, but due to very
Thickness, necessarily cause deadweight very big, it is clear that this is totally unfavorable to earthquake resistant engineering.During geological process, huge weight can cause
Very big horizontal earthquake action, is acted on floor in the form of load, the floor interlayer below the load position
Displacement becomes larger, and the plane stiffness of Thick Plate Transfer Story and vertical stiffness are all big, thus the interlayer of adjacent upper and lower layer anti-pushes away
Rigidity is relatively small, reforms into " weak layer ", so as to exacerbate the concentration of plastic deformation effect of adjacent layer, further increases
The relative storey displacement value of upper and lower floor.Therefore, it is highly desirable to seek the effective measures for improving conversion beam stress performance.
The content of the invention
The technical problem to be solved in the present invention, it is to provide a kind of more Pin space trusses transformational structures.
What the present invention was realized in：A kind of more Pin space trusses transformational structures, including four truss and four pillars, described four
Truss is end to end to enclose a square body, and four pillar is connected to four right angles of the square body；The purlin
Frame winds up including one, a lower edge and a plurality of posts；Described wind up be arranged in parallel with lower edge, and a plurality of posts are parallel
And interval is located at and winded up between lower edge, and the top of the post is stretched out and winded up.
It is preferred that the truss also includes a plurality of diagonal web members, it is small that a plurality of diagonal web members are staggeredly fixed on two two-by-two
Between column, or between post and pillar, and diagonal web member, post and wind up or lower edge three between form three-legged structure.
It is preferred that the truss also includes a plurality of connecting plates, the diagonal web member, post and wind up or lower edge three it
Between pass through the connecting plate and connect.
The advantage of the invention is that：Bending resistance and the shear resistance of beam are improved well, have section small, deadweight is lighter excellent
Point.
Brief description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of the more Pin space trusses transformational structures of the present invention.
Embodiment
Refer to shown in Fig. 1, a kind of more Pin space trusses transformational structures 100, including four truss 1 and four pillars 2,；It is described
Four truss 1 are end to end to enclose a square body M, and four pillar 2 is connected to four right angles of the square body M；
The truss 1 winds up 11, one lower edge 12, a plurality of posts 13, a plurality of diagonal web members 14 and a plurality of connecting plates 15 including one；
It is described wind up 11 and lower edge 12 be arranged in parallel, a plurality of posts 13 it is parallel and interval located at wind up 11 and lower edge 12 it
Between, and the top of the post 13 is stretched out and winds up 11.
Referring again to Fig. 1, a plurality of diagonal web members 14 are staggeredly fixed between two posts 13 two-by-two, or post 13
Between pillar 2, and diagonal web member 14, post 13 and wind up and form three-legged structure between 11 or the three of lower edge 12.The oblique abdomen
Bar 14, post 13 and winding up is connected between 11 or the three of lower edge 12 by a connecting plate 15, diagonal web member 14, post
13rd, wind up and high-strength bolt connection (not shown) is used by connecting plate 15 between 11, lower edge 12.
The more transformational structures 100 of Pin space trusses 1 of the present invention, using steel modulus of elasticity, tension and compression strength compared with
The characteristics of big, bending resistance and the shear resistance of beam are improved well；It is small with section compared to conventional steel bar concrete conversion layer, from
Weight is lighter, and can be directed to the flexible horizontally disposed position changed per truss structure 1 of up-down structure power transmission demand and the inside of truss 1 tiltedly
Web member 14 and column combining form.
Although the foregoing describing the embodiment of the present invention, those familiar with the art should manage
Solution, the specific embodiment described by us are merely exemplary, rather than for the restriction to the scope of the present invention, are familiar with this
The equivalent modification and change that the technical staff in field is made in the spirit according to the present invention, should all cover the present invention's
In scope of the claimed protection.
