Description

Three-dimensional intersection truss conversion layer structure
Technical field
The utility model relates to building field, relates to a kind of three-dimensional intersection truss conversion layer structure.
Background technology
Conversion layer of the prior art is beam-type transition layer mostly, and its design and construction are simple, stressed clear and definite, is generally used for shear wall structure with large width.More when upper lower prop net, axis misalignment, while being difficult to by the direct support of beam, can make slab or box-type change-over floor, but its deadweight is larger, material consumption is more, and computational analysis is also more complicated.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of three-dimensional intersection truss conversion layer structure is provided, and can meet the requirement of Large Span Transition Floor, and construction is simple, and construction cost is low.
The utility model solves the technical scheme that its technical problem adopts: construct a kind of three-dimensional and intersect truss conversion layer structure, comprise three-dimensional intersection truss and Vierendeel girder, described three-dimensional intersection truss comprises upper chord, lower chord, perpendicular web member, diagonal web member, described lower chord and diagonal web member are welded on the same Nodes of described perpendicular web member, described upper chord is welded on described perpendicular web member, described diagonal web member connects upper chord and lower chord, two adjacent perpendicular web members are connected with lower chord by upper chord, and described Vierendeel girder is fixed on the top of described perpendicular web member.
In such scheme, the outside of described perpendicular web member is welded and fixed outer ring plate, and described lower chord is welded on described outer ring plate.
In such scheme, described perpendicular web member is round steel pipe.
In such scheme, described diagonal web member is square steel pipe.
In such scheme, described Vierendeel girder is spliced to form by H shaped steel.
Implement three-dimensional intersection truss conversion layer structure of the present utility model, there is following beneficial effect:
1, the novel conversion layer structure that three-dimensional intersection truss forms, has alleviated deadweight, and has increased cross section resistance moment, can significantly improve the Rigidity and strength of structure, thereby can bear larger load in the time of certain span.
2, equipment installation passes in truss, can reduce building floor height, reduces on the whole construction cost.
3, relatively board-like, beam-type transition layer, material usage is economized, and energy saving construction cost, improves business efficiency.
4, between upper chord, lower chord, perpendicular web member and diagonal web member, all adopt and be welded to connect, form the connected node of perfect rigidity, can transmit moment of flexure, also simplified node calculating simultaneously, the reliability that has ensured node bonding strength, has met the requirement of Large Span Transition Floor, has realized the perfect unity of Architecture and structure, simplify construction, saved construction cost.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the schematic diagram of the utility model three-dimensional intersection truss conversion layer structure;
Fig. 2 conversion layer and structural representation more than conversion layer;
The structural representation of Fig. 3 conversion layer lower-chord panel point.
Detailed description of the invention
Understand for technical characterictic of the present utility model, object and effect being had more clearly, now contrast accompanying drawing and describe detailed description of the invention of the present utility model in detail.
As shown in Figure 1-Figure 3, three-dimensional intersection truss conversion layer structure of the present utility model comprises three-dimensional intersection truss and Vierendeel girder 5, and wherein three-dimensional intersection truss comprises upper chord 2, lower chord 1, perpendicular web member 3, diagonal web member 4.
Lower chord 1 and diagonal web member 4 are welded on the same Nodes of perpendicular web member 3, and upper chord 2 is welded on perpendicular web member 3, and diagonal web member 4 connects upper chord 2 and lower chord 1, and diagonal web member 4 is also fixedly connected with by the mode of welding with upper chord 2.The outside of perpendicular web member 3 is welded and fixed outer ring plate 6, and lower chord 1 is welded on outer ring plate 6.Perpendicular web member 3 in the present embodiment is round steel pipe, and diagonal web member 4 is square steel pipe, and Vierendeel girder 5 is spliced to form by H shaped steel.
When construction, first according to building function requirement, make the above or following two-layer post position of conversion coating, then according to post position, reasonably mark off three-way grid at the upper and lower string face of conversion layer, and give this three-way grid by square-section steel pipe, form the upper and lower string of conversion layer three-dimensional truss; According to the span of conversion layer truss and the size of required bearing load, make the height of conversion layer three-dimensional truss, highly general value is span 1/10~1/18, truss frame for connecting winds up, the node of lower edge, forms perpendicular web member 3 and the diagonal web member 4 of truss.
The production technology of above-described embodiment is: first on the perpendicular web member 3 of the truss of round steel pipe composition, weld outer ring plate 6, secondly welding lower chord 1 and diagonal web member 4; In like manner can weld upper chord 2, form the conversion layer being formed by three-dimensional truss, finally weld Vierendeel girder 5 more than conversion layer, form total.
Two adjacent perpendicular web members 3 are connected with lower chord 1 by upper chord 2, and Vierendeel girder 5 is fixed on the top of perpendicular web member 3.The perpendicular web member 3 that three-dimensional is intersected in truss is also held concurrently and is supported the support column of the above structure of conversion layer.The novel conversion layer structure that three-dimensional intersection truss forms, has alleviated deadweight, and has increased cross section resistance moment, can significantly improve the Rigidity and strength of structure, thereby can bear larger load in the time of certain span.
In the present embodiment, between upper chord 2, lower chord 1, perpendicular web member 3 and diagonal web member 4, all adopt and be welded to connect, form the connected node of perfect rigidity, can transmit moment of flexure, also simplify node calculating, ensured the reliability of node bonding strength simultaneously, meet the requirement of Large Span Transition Floor, realize the perfect unity of Architecture and structure, simplified construction, saved construction cost.Equipment installation passes in truss, can reduce building floor height, reduces on the whole construction cost.Relatively board-like, beam-type transition layer, material usage is economized, and energy saving construction cost, improves business efficiency.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
