Description

Space frame

The invention relates to a kind of space frame.

Space frame is employed very widely, especially under some environment, need be with minimum pillar and maximum unremitting ground space, and on a wide ground, erect a top cover.Space frame is generally double-deck form, comprising the upper and lower grid of separated band vertical and horizontal chord.The node of last Under The Grille (being the contact of chord member) is that strut or the diagonal brace that is tilted is being connected to each other.This two-layer grid is longitudinally with relative dislocation laterally, therefore except on the edge of upper strata grid, each node on any one deck grid, all be with equidistantly with another layer grid on four nodes be connected with the inclination strut.On this each node, must take measures to make and intersect chord and mutual firm connection of a succession of inclination strut.

The common preferably member of tubular of chord and strut, and the axis of vertical and horizontal chord and strut preferably intersects on node.The space frame that meets these needs has connector and chord and brace member usually, but their manufacturing cost costliness is installed pretty troublesome.

The object of the present invention is to provide a kind of space frame of as above-mentioned form, chord wherein and brace member can be simply and are manufactured economically, also can be rapidly with easily and with the mutual alignment of the best couple together rigidly.

According to aforementioned or other purposes, the present invention briefly belongs to space frame, its form be include band vertically and the branch of horizontal chord across upper and lower two-layer grid, the strut that the node of upper and lower two-layer grid is tilted is being connected to each other.On the node wherein, the junction plate that horizontal, vertical chord section saves terminal approximate vertical is placed in the criss-cross built-up member; At inclination strut two ends, mutually perpendicular flange is engaged with in the cross assembling obliquely; Securing member is fixed together the junction plate that inserts in the flange of one by one strut and the cross assembling.Horizontal and vertical chord is tubular preferably, and the terminal part that is flattened of horizontal, vertical chord section joint is a junction plate.Strut preferably also is a tubular, and the end of each strut is flattened and by flexion, in order to forming two above-mentioned vertical flanges, and the axis of the intersecting lens of this two flange and the chord master cylindrical portions may angle that tilts.Other characteristics of the present invention will be showed to come from following description.

In order to make the easier quilt of optimum implementation of the present invention understand and implement, be described as follows with reference to the accompanying drawings now,

Fig. 1 is the graphic plan view that includes according to the building part of space frame of the present invention,

Fig. 2 is a certain node of space frame upper strata grid, the lateral view of the node in the circle 2 among Fig. 1 for example,

Fig. 3 is the vertical view of node shown in Figure 2,

Fig. 4 is the bottom view of node shown in Figure 2,

Fig. 5 is the phantom drawing of a certain inclination strut of space frame end portion,

Fig. 6 is the sectional view of 6-6 along the line among Fig. 1, on the ratio greater than Fig. 1, but less than Fig. 2,3 and 4.

Described space frame has a upper strata grid with vertical chord 10 and horizontal chord 11, and a lower floor's grid with vertical chord 12 and horizontal chord 13 is arranged, with the inclination strut 14 that is being connected levels grid node (being the chord interface point).Space frame flatly by support within exterior wall 15, include vertical space support support 16 here, it is also as the window mullion of glassing, space frame support landing ground panel 17, and at its next ceiling panel 18 of having settled.

Fig. 2, on the space frame upper strata grid node that shows in 3 and 4,10, two sections horizontal chords 11 of a vertical chord member and four inclination struts 14 are being connected rigidly, and all these members all are the round metal tubular pipes of same diameter.

On node, vertically chord member 10 is flattened, to form vertical junction plate 19, laterally the end of chord section 11 on node also is flattened, forming vertical junction plate 20, these two junction plates 20 in line and vertical with the two sides at junction plate 19 middle parts form the cross assembling.

Four inclination struts 14 are identical, all being flattened by the stamped metal operation in two ends separately, is done into position, angle member with quilt, and wherein two flanges 21 are mutually perpendicular, their handing-over line 22 favours the axis of strut master cylinder, and each flange 21 respectively has two bolts hole 23.

Vertically have hole to form (not showing) on the vertical junction plate 19 of chord member 10, laterally the vertical junction plate 20 of chord section 11 also has simultaneously.These bolts hole should dispose like this, promptly when strut 14 is being laid as shown in the figure, the knuckle end of strut is placed in chord in length and breadth and is flattened in the position, a certain angle in the cross assembling of vertical junction plate, should make two strut flanges 21 and middle chord member junction plate 19 that inserts and 20 hole aligning, bolt 24 just can pass the hole and the nut 25 of alignment and tighten, and whole composite member is firmly fixed together.Shown in Fig. 2 chain-dotted line, each is the manufacturing and the arrangement of part in addition, and the axis of each chord member and brace member is all intersected on the single point.

The horizontal chord of space frame is except the Duan Jie that is made into end and is flattened, with vertical chord member similarly, each horizontal chord also can be flattened outside node, wherein one be flattened part at last fluting, other are then being slotted down, therefore at each node place in length and breadth chord member just contain mutually and connect, their axis is then at grade.

Other method is, vertically and horizontal chord can with several sections similar section formed, be flattened separately with drilled hole in two ends, therefore at each node place, two sections vertical chord sections and two sections horizontal chord sections are just taken among the cross assembling together, then just between 21 pairs of strut 14 flanges with bolt together.

In above-mentioned space frame, the edge of upper strata grid and terminal the stretching, extension surmount lower floor's grid, simultaneously at the node place of grid periphery, upper strata (except the node of position, angle), have only two inclination struts connecting.

At these node places, simple fish plate (not having to show) uses bolton in the outward flange of node.At node place, position, grid angle, upper strata,, single inclination strut and simple angle bracket (not having to show) use the outside of bolton here at the angle from being arranged.

Just because of whole brace member of space frame can be identical, whole vertically chords of each layer grid can be similar, with whole laterally chord section joints of space frame can also be similar, therefore the variant member that is used for this structure can reach manufactured economically simply, and can also not need advanced skill ground and apace with bolton together.If vertically chord and laterally chord be both and be made into Duan Jie, just so whole space frame can that is to say only to set up with two kinds of basic structure members, set up with similar strut with similar chord member.

Ground panel 17 can be to form with the steel concrete casting, be foursquare in plan view, as shown in Figure 6, the core of each panel 17 is the thickest, four limits then are decreased to the thinnest gradually, just risen by the grid institute support of a ground panel support 26 at this four limits panel 17, the shape of cross section of support 26 is reversing T shapes, is fixed on the grid of upper strata with welding or other ways.Ceiling panel 18 can be the fire-proof sound insulation material, also can be foursquare and also can in four limit supports with T shape rod 27 grids, and this T shape rod can be mounted under space frame lower floor grid with suitable method.

If space frame does not need support one roof, node cap shown among Fig. 2 28 just can be applied on the space frame node, shown in cap be columniform, its top seal, then there is slit 29 to form in the bottom, in order to put on the node end of chord and strut, similar cap also can reverse and be used on lower floor's grid node, and the cap of levels is can be fixing with any suitable method.
