Description

More Pin space trusses transformational structures

Technical field

The utility model is specifically related 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. Since various complex shapes largely occur, the column 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 that the effective of structure stress transmits, 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 common 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 generally 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 column 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, can produce obvious stress concentration phenomenon if opening holes.Thick Plate Transfer Story, even if because shape is simple, but due to very Thickness, necessarily causes dead weight 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 resists and 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.

Utility model content

The technical problems to be solved in the utility model, is to provide a kind of more Pin space trusses transformational structures.

The utility model is realized in this way：A kind of more Pin space trusses transformational structures, including four truss and four pillars, institute State that four truss are end to end to enclose a square body, four pillar is connected to four right angles of the square body；Institute State truss wind up including one, a lower edge and a plurality of posts；Described wind up is arranged in parallel with lower edge, a plurality of posts Parallel and interval, which is arranged on, winds up between lower edge, and the top of the post is stretched out and winds up.

It is preferred that the truss further 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 further 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 utility model has the advantage of：Bending resistance and the shear resistance of beam are improved well, have section small, dead weight is lighter The advantages of.

Brief description of the drawings

The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the structure diagram of the more Pin space trusses transformational structures of the utility model.

Embodiment

Refering to Figure 1, a kind of more Pin space trusses transformational structures 100, including four truss 1 and four pillars 2；Described four Truss 1 is end to end to enclose a square body M, and four pillar 2 is connected to four right angles of the square body M；Institute Truss 1 is stated to wind 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；Institute State wind up 11 and lower edge 12 be arranged in parallel, a plurality of posts 13 it is parallel and interval be arranged on wind up between 11 and lower edge 12, 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 12 three of lower edge.The oblique abdomen Bar 14, post 13 and winding up is connected between 11 or 12 three of lower edge 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.

More 1 transformational structures 100 of Pin space trusses of the present invention, using steel elasticity modulus, tension and compression strength compared with The characteristics of big, improve bending resistance and the shear resistance of beam 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 specific embodiment of the present utility model, those familiar with the art should Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Equivalent modification and change fixed, that those skilled in the art are made in the spirit according to the utility model, all should Cover in the scope of the claimed protection of the utility model.
