In this embodiment, the main truss 201 and the secondary truss 202 are spliced by the splicing assembly 30, in which the splicing assembly 30 is actually formed by a plurality of steel sleeve assemblies 1 together, and in this embodiment, the splicing assembly 30 includes two structural forms, wherein when the splicing assembly 30 is located at the edge of the combined truss structure 20, the structure of the splicing assembly includes two steel sleeve assemblies 1, the directions of the two steel sleeve assemblies 1 for sleeving the raw bamboo rod 2 are mutually perpendicular, one steel sleeve assembly 1 belongs to the main truss 201 structure, and the other steel sleeve assembly 1 belongs to the secondary truss 202; another type of structure includes three steel sleeve assemblies 1 when the splice assemblies 30 are positioned in the middle of the composite truss structure 20, wherein one splice assembly 30 is divided into a main truss 201 structure, the other two splice assemblies 30 are divided into a sub-truss 202 structure, and the two splice assemblies 30 divided into sub-trusses 202 structure are respectively arranged at two sides of the splice assemblies 30 divided into the main truss 201 structure. Specifically, the splicing assembly 30 is a structure formed after the main truss 201 and the secondary truss 202 are spliced, before splicing, a connecting plate 3 is required to be arranged on two sides of the steel sleeve assembly 1 on the main truss 201 structure through means such as welding, and meanwhile, a connecting plate 3 is arranged on one side of the end parts of the steel sleeve assemblies 1 at two ends of the secondary truss 202 through means such as welding, and when the main truss 201 and the secondary truss 202 are spliced, the two connecting plates 3 are connected through connection modes such as bolts and bolts; and under the premise of comprehensively considering the structural stability, bearing capacity and construction cost of the combined truss structure 20, in this embodiment, the secondary truss 202 is spliced with the main truss 201 in a span-separating construction mode (that is, the secondary trusses 202 erected on the two main trusses 201 need to be erected in a span-separating mode, and a steel sleeve assembly 1 is preferably arranged between the two adjacent secondary trusses 202), so that the structural strength of the combined truss structure 20 can be ensured, the supporting effect on the concrete floor slab 10 is realized, and meanwhile, the use of the secondary trusses 202 can be effectively reduced, and the construction cost is reduced. Meanwhile, the inside of the original bamboo rod piece 2 can be opened for arrangement of pipelines in the specific construction process, so that additional holes on a floor slab can be avoided, the structural characteristics of the original bamboo rod piece 2 can be reasonably and effectively utilized, and the construction cost can be further reduced while the construction process is reduced.
The steel sleeve assembly 1 comprises a floor slab connecting part 11 and an original bamboo rod piece sleeving part 12, wherein the original bamboo rod piece sleeving part 12 is arranged at the bottom of the floor slab connecting part 11, and the original bamboo rod piece sleeving part 12 is perpendicular to the floor slab connecting part 11; the floor slab connecting part 11 is fixedly connected with the concrete floor slab 10; the original bamboo pole piece sleeving part 12 is sleeved on the original bamboo pole piece 2. In this embodiment, the steel sleeve assembly 1 is preferably a "T" shaped steel sleeve formed by two steel plates, i.e. one horizontal steel plate forms the floor slab connecting portion 11, one vertical steel plate forms the original bamboo rod member sleeving portion 12, and in order to ensure that the whole composite truss structure 20 is stressed uniformly, the vertical steel plates need to be arranged along the central line of the horizontal steel plates, and the two steel plates can be welded or integrally formed to achieve the connecting effect.
In this embodiment, in order to improve the bearing capacity of the composite truss structure 20, the raw bamboo rod member sleeving part 12 is provided with a plurality of raw bamboo holes 121, and each raw bamboo hole 121 is sleeved with a raw bamboo rod member 2. In this structure, the weight of the concrete floor board 10 is shared by the plurality of original bamboo pole pieces 2, so that the stability and safety of the structure can be effectively improved.
The plurality of raw bamboo holes 121 are formed at positions where one of the raw bamboo holes 121 is formed at the center of the raw bamboo rod sleeving part 12, and the positions of the rest raw bamboo holes 121 are located on diagonal lines of the raw bamboo rod sleeving part 12 and are close to four corners of the raw bamboo rod sleeving part 12. In this embodiment, the setting positions of the multiple raw bamboo rods 2 can more effectively enhance the bearing capacity of the composite truss structure 20; the enhanced bearing capacity of the structure is realized not only by arranging a plurality of original bamboo pole pieces 2, but also by matching the opening positions of the original bamboo holes 121.
Two rows of threaded holes are formed in the floor connecting portion 11, the two rows of threaded holes are symmetrical with respect to the original bamboo pole piece sleeving portion 12, and a plurality of threaded holes are correspondingly formed in the concrete floor plate 10. When the concrete floor plate 10 is connected with the floor plate connecting part 11, threaded holes on the concrete floor plate 10 and the floor plate connecting part 11 are coaxial and fixedly connected by bolts 5. In this embodiment, the connection between the concrete floor slab 10 and the floor slab connection portion 11 is preferably in the form of a bolt connection, but the same manner of inserting, pinning, etc. that can effectively achieve the connection effect may be equivalently replaced with the bolt connection used in this embodiment. In order to make the connection better and to make full use of the load carrying capacity of the composite truss structure 20, preferably two rows of said threaded holes are symmetrical about said primary bamboo pole piece socket 12 (i.e. two rows of said threaded holes are symmetrically arranged about the midline of said floor slab connection 11).
The hoop member 6 is arranged on the raw bamboo member 2 close to the raw bamboo member sleeving part 12. If the mounting limiting effect on the original bamboo pole piece 2 is achieved only through the original bamboo hole 121 formed in the original bamboo pole piece sleeving part 12, the problem that the original bamboo pole piece 2 is likely to move and the like can occur, so in the embodiment, the problem that the original bamboo pole piece 2 moves is prevented by arranging the hoop piece 6 on the original bamboo pole piece 2, wherein the hoop piece 6 needs to be arranged close to the original bamboo pole piece sleeving part 12, one side of the hoop piece 6 needs to be clung to the original bamboo pole piece sleeving part 12, and then the hoop piece 6 is blocked through the original bamboo pole piece sleeving part 12, so that the original bamboo pole piece 2 can be effectively prevented from moving, and the integrity and stability of a floor slab structure are improved.
The bottom of the sleeving part 12 of the original bamboo rod piece is also provided with a plurality of steel strand holes 122, and each steel strand hole 122 is internally penetrated with one steel strand 7. In this embodiment, for truss units with larger stress, the bending resistance of the truss units can be improved by adding the steel strands 7 at the lower parts of the truss units, and the two ends of each steel strand 7 need to be anchored into the constraint members at the ends of the truss units, so that the integrity and the bearing capacity of the composite floor slab are improved, and meanwhile, the integral composite floor slab is prevented from being invalid after the original bamboo rod piece 2 is invalid as a second paying-off line.
The foregoing description of the embodiments has been provided for the purpose of illustrating the general principles of the invention, and is not meant to limit the scope of the invention, but to limit the invention to the particular embodiments, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the invention are intended to be included within the scope of the invention.
