In order to more clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will now be described with reference to the accompanying drawings.
As shown in fig. 1 to 13, the present embodiment provides a splicing node structure of a truss, which at least includes two adjacent segmented trusses 100, each segmented truss 100 includes an upper chord 1 and a lower chord 2, an end vertical rod 3 is disposed at an end of each segmented truss 100, the end vertical rod 3 is fixedly connected to the upper chord 1 and the lower chord 2, and two end vertical rods 3 of two adjacent segmented trusses 100 are detachably and fixedly connected through a plurality of fixing members 4.
In a factory, the segmented trusses 100 are spliced respectively, and then the segmented trusses 100 are transported to a construction site; on the construction site, the two adjacent end vertical rods 3 are fixedly connected through a plurality of fixing pieces 4 in the air, so that the node splicing between the two adjacent segmented trusses 100 can be completed. It can be understood that a whole truss is formed by splicing a plurality of the above-mentioned segmented trusses 100, and during construction, two adjacent segmented trusses 100 are node-spliced by a plurality of fixing members 4 in the above-mentioned manner, so that the segments of one truss can be sequentially connected to form the whole truss.
From this, concatenation node structure in this embodiment sets up end montant 3 through the tip at every segmentation truss 100, when splicing each segmentation truss 100 on the scene, only needs to utilize a plurality of mountings 4 to fix in the air and can accomplish the concatenation, need not to weld node position in the air, the overhead welding volume that has significantly reduced has reduced the construction degree of difficulty to the time limit for a project has been shortened. Meanwhile, compared with the splicing mode adopting the connecting pieces in the prior art, the upper chord 1 and the lower chord 2 in the prior art need to be spliced through the separate connecting pieces respectively, and the number of the connecting pieces is large; in this embodiment, the upper chord 1 and the lower chord 2 can be spliced together through the end vertical rod 3 connected together, and the number of members to be spliced is less. In addition, the end of each segmented truss 100 is provided with an end vertical rod 3, and the upper chord 1 and the lower chord 2 in each segmented truss 100 are not provided with cantilevers, so that the segmented truss 100 is effectively prevented from deforming or being damaged in the transportation and construction processes.
In a specific implementation, for easier installation and structural stability, the end vertical bar 3 is a first T-shaped steel including a first flange plate 31 and a first web plate 32 perpendicular to each other. The first flange plate 31 is arranged at the end of the segmented truss 100, the plate surface of the first flange plate is perpendicular to the plane where the center lines of the upper chord 1 and the lower chord 2 are located, and the two ends of the first web plate 32 are respectively inserted into the upper chord 1 and the lower chord 2 and are welded and fixed. The two first flange plates 31 of the two adjacent segmented trusses 100 are detachably fixedly connected by a plurality of fixing members 4.
During construction, in a factory, the first web plate 32 of each segmented truss 100 is firstly inserted into the upper chord 1 and the chord and welded and fixed, so that each segmented truss 100 is spliced; after the first flange plates 31 are transported to a construction site, the two adjacent first flange plates 31 are fixedly connected in the air through the fixing pieces 4, and therefore node splicing can be completed, and the method is simple and convenient.
It can be understood that, according to the shape requirement of the truss, the center line of the upper chord 1 and the center line of the lower chord 2 in each segmented truss 100 may be parallel to each other as shown in fig. 1, and the center lines of the chords are perpendicular to the end vertical bars 3; the central line of the upper chord 1 and the central line of the lower chord 2 in each segmented truss 100 are not parallel to each other, and at the moment, the central lines of the chords are not perpendicular to the end vertical rods 3 any more; but the plane of the centre line of each chord is always perpendicular to the face of the first flange plate 31.
Preferably, in order to ensure the structural stability of the splice node, as shown in fig. 3, a plurality of fixing members 4 are symmetrically distributed on both sides of the first web 32. In addition, the fixing member 4 is preferably a high-strength bolt, and particularly for a heavy truss which has a large number of rods and needs to bear a large load, the high-strength bolt can better meet the stress requirement, and the construction is convenient.
In practical application, the first web 32 is connected to the upper chord 1 and the lower chord 2 in a slightly different manner according to different structural forms of the upper chord 1 and the lower chord 2, and there are mainly the following cases:
(1) as shown in fig. 1 to 5, the upper chord member 1 and/or the lower chord member 2 is an H-section steel including an upper flange plate 11, a lower flange plate 12, and an intermediate web 13 connected between the upper flange plate 11 and the lower flange plate 12. The end part of the H-shaped steel, which is opposite to the middle web plate 13, is provided with a slot 6 which penetrates through the upper flange plate 11 and the lower flange plate 12 along the length direction, and the first web plate 32 is inserted into the slot 6 and is welded and fixed.
(2) As shown in fig. 1 to 3, the upper chord 1 and/or the lower chord 2 is a second T-shaped steel including a second flange plate 21 and a second web plate 22 perpendicular to each other. And a slot 6 penetrating through the second flange plate 21 is formed in the position, opposite to the second web plate 22, of the end part of the second T-shaped steel along the length direction of the second T-shaped steel, and the first web plate 32 is inserted into the slot 6 and is welded and fixed.
The second T-section steel referred to herein is a conventional T-section steel in the same structure as the first T-section steel described above. It can be understood that, when in use, generally, the upper chord member 1 and the lower chord member 2 both adopt H-shaped steel, or both adopt second T-shaped steel, or one adopts H-shaped steel, and the other adopts second T-shaped steel for combined use.
(3) As shown in fig. 7 to 9, the upper chord 1 and the lower chord 2 are double-angle steel, the double-angle steel includes two single-angle steels 14 arranged at intervals back to back, and the first web 32 is inserted into a gap between the two single-angle steels 14 and is welded and fixed.
In general, in order to enhance structural stability, a filler plate 15 is welded between two single angles 14 of the same double angle, and the number of the filler plates 15 is determined as necessary.
(4) As shown in fig. 10 to 13, the upper chord 1 and the lower chord 2 are both steel pipes 16, two slots 6 are symmetrically formed in the end pipe wall of each steel pipe 16, and the first web 32 is inserted into the two slots 6 and welded and fixed. It will be appreciated that both slots 6 now extend to the end of the steel tube 16. The steel pipe 16 is preferably a round pipe.
It can be understood that when the upper chord member 1 and/or the lower chord member 2 are H-shaped steel, the plate surface of the first flange plate 31 is perpendicular to the plane of the middle web plate 13; when the upper chord member 1 and/or the lower chord member 2 are second T-shaped steel, the plate surface of the first flange plate 31 is perpendicular to the plane of the second web plate 22; when the upper chord 1 and the lower chord 2 are both double-angle steel, the plate surface of the first flange plate 31 is perpendicular to the planes of two panels arranged back-to-back of the two single-angle steel 14; when the upper chord 1 and the lower chord 2 are both steel pipes 16, the plate surface of the first flange plate 31 is perpendicular to the plane where the axes of the two steel pipes 16 are located.
Of course, other configurations of the upper chord 1 and the lower chord 2 may be adopted, and this embodiment is merely an example.
Further, in order to ensure the stability of the truss structure, each of the segmented trusses 100 further includes an oblique web member 5 disposed between the upper chord member 1 and the lower chord member 2, and both ends of the oblique web member 5 are respectively fixed to the end vertical members 3 at both ends of the same segmented truss 100.
Wherein, both ends of the diagonal web member 5 are welded and fixed with the corresponding first web plate 32. The diagonal web member 5 may also be H-shaped steel, T-shaped steel, double angle steel, or steel pipe as required; when the diagonal web member 5 is made of a steel pipe, a groove is formed in the end portion of the steel pipe, and then the first web plate 32 is inserted and welded. In addition, the width of the first web 32 in the end vertical rod 3 depends on the strength requirement, and generally, the width of the first web 32 is relatively wider at the position where the diagonal web member 5 is connected, and the width of the rest of the first web 32 is relatively narrower.
In summary, in the splicing node structure in the embodiment, the end of each segmented truss 100 adopts a T-shaped cross section with equal strength welding as the end vertical rod 3, and the upper chord, the lower chord and the diagonal web member 5 of each segmented truss 100 are respectively connected with the end vertical rod 3 through welding; the end vertical rods 3 of the two T-shaped cross sections in the air are connected through high-strength bolts to form a cross-shaped cross section which is used as a vertical web member of the integral truss; the high-strength bolt group is stressed to have equal strength with the internal force at the node. In the embodiment, the high-strength bolt splicing nodes are adopted on the site to splice the segmented trusses 100 into a whole truss, so that the problem of splicing trusses, particularly heavy trusses in sections in the air is solved, the stress requirement can be completely met, and compared with a common truss splicing mode in the prior art, the truss splicing node has the advantages of simple structure, convenience in construction, construction period saving, capability of solving the problem that the upper chord 1 and the lower chord 2 are easy to deform and damage in the transportation and construction processes, and convenience in component transportation and installation is realized.
The above are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the invention should fall within the protection scope of the invention.
