The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with referring to Fig. 1-Fig. 6, for the two-way oblique of the utility model is opened the embodiment mono-of string beam.
As shown in Figure 1, the two-way oblique in the present embodiment is opened string beam, comprising: many Pin pipe truss 1, and in the present embodiment, manage truss 1 and be made as 6 Pin, between it, by a plurality of strong points, equidistantly to arrange, the effect of pipe truss 1 is to bear vertical pressure and reverse pressure power.
Between adjacent two Pin pipe truss 1, many Pin are set and laterally open string beam 2, in the present embodiment, be respectively equipped with 2 Pin and laterally open string beam 2 between adjacent two Pin pipe truss 1, integral body is made as 10 Pin.Two 1 of truss of Pin pipe comprise two Pin laterally open string beam 2 four interior transverse members between two distance arrange equally, form stable in order to bear the structural member of vertical pressure.
Further, pipe truss 1 arranges respectively the first strong point T1 and second strong point T2 that can be connected at grade with the top of laterally opening string beam 2 with bottom, and the middle part of pipe truss 1 arranges the 3rd strong point T3; By the fastening support to the first strong point T1, the second strong point T2 and the 3rd strong point T3, make many Pin pipe truss 1 and many Pin laterally open 2, string beam and present arciform curved surface, form unique evagination surface modeling.During concrete enforcement, pipe truss 1 can use many to be arciform steel tube lapping and to form, and first strong point T1 at two ends, the second strong point T2 can be used the form of structure of bearing, and the 3rd strong point T3 can be used the form of structure of support column.Pipe truss 1 and laterally a string beam 2 form the transversary of these curved surface frameworks, and the set quantity of pipe truss 1 be only 1/3rd of lateral stressed member, make the structure scale of construction remain on reduced levels, the more slim and graceful dexterity of architectural image.
Please with further reference to Fig. 2, the two-way oblique of the present embodiment is opened string beam and is also comprised: many Pin put forth effort to be connected to longitudinally string beam 3 and the Duo Gen connecting rod 4 on pipe truss 1, a longitudinally string beam 3 in the present embodiment is made as 3 Pin, be fastened on successively pipe truss 1 arrange the 3rd strong point T3 near, every Pin longitudinally opens string beam 3 and laterally opens string beam 2 with many Pin and form the prestressed structure that transverse and longitudinals are arranged.Connecting rod 4 is arranged in the longitudinally surrounding of a string beam 3 and the bottom of pipe truss 1, and connecting rod 4 and longitudinally a string beam 3 form the vertical structure of this curved surface framework.

Further, manage truss 1, laterally opening string beam 2, longitudinally opening between any two members in string beam 3 and connecting rod 4 intertie 5 is set.For example at pipe truss 1 with longitudinal 3, a string beam, laterally open 4, string beam 2 and connecting rod, manage 4, truss 1 and connecting rod etc., the effect of intertie 5 is that two members are carried out firmly.
In conjunction with referring to Fig. 3, for transverse and longitudinal is opened the structural representation of string beam phase " oblique ", further, longitudinally opening string beam 3 comprises: laterally to open string beam 2 cross-coupled in order to the first common stressed longitudinal longitudinal longitudinal string beam 3c of a string beam 3b and the 3rd of a string beam 3a, second of an auxiliary laterally string beam with many Pin pipe truss 1 and many Pin respectively.Gai San road longitudinally opens string beam 3a, 3b and the distributing position of 3c on pipe truss 1 refers to Fig. 4, for managing the cross section structure schematic diagram of truss in the present embodiment, wherein, three roads longitudinally open string beam 3a, 3b and 3c be arranged in respectively the 3rd strong point T3 near, and a strong point of the 3rd strong point T3 puts forth effort to be connected to second longitudinally on a string beam 3b.That is to say, according to different structural strengths and difficulty of construction, the 3rd strong point T3 can have one or more strong points to put forth effort to be connected to arbitrary road longitudinally to open string beam 3a, 3b or 3c upper, in order to strengthen the longitudinally auxiliary stressed effect of a string beam 3.
Further, from its middle part, the sectional dimension convergent to its both sides narrows pipe truss 1, and it can further increase the usage space in structure; Pipe truss 1 can bear vertical pressure and reverse pressure power, strengthens the effect of structure reversed load.
In the present embodiment longitudinally a string beam 3 or connecting rod 4 and pipe truss 1 or laterally open string beam 2 respectively the projection angle of cut on horizontal plane be 73 °.Through force analysis, when between this transverse member and longitudinal member, the horizontal projection angle of cut is 73 °, laterally the internal force impact between a string beam 2 and longitudinal string beam 3 is minimum, can give full play to and laterally open string beam 2 in order to bear vertical pressure and longitudinally to open the auxiliary laterally common stressed effect of string beam 2 of string beam 3.
Preferably, many connecting rods 4 are made as respectively many steel pipes that are parallel to each other.
Please with further reference to Fig. 5, be the horizontal cross section structure schematic diagram of a string beam in the present embodiment, wherein: laterally open string beam 2 and comprise: the first pressurized steel pipe 21, it is one to move towards identical single steel pipe with managing truss 1, can be also other rigid structures;
Be connected to the first strut 22 on the first pressurized steel pipe 21, it is made as three steel pipes that parallel; And
Be connected between the first strut 22 and the first pressurized steel pipe 21 and the first strut 22 between first be subject to drawing steel stranded wire 23.In the present embodiment, first is subject to 23 of drawing steel stranded wires to play tension effect, linearly.Be subject to drawing steel stranded wire 23 cross sections little due to first, overall perception is merrily and lightheartedly beautiful, further increases usage space in structure; And be also easy to manufacture, transport and construction.
Please with further reference to Fig. 6, for longitudinally opening the cross section structure schematic diagram of string beam in the present embodiment, wherein: longitudinally open string beam 3 and comprise: the second pressurized steel pipe 31, it is a single steel pipe intersecting with pipe truss 1 and the first pressurized steel pipe 21, it can be also other rigid structures;
