Description

Technical Field

[0001] The utility model relates to the technical field of building structures, and particularly relates to a recombined bamboo cable-supported truss structure. Background Art

[0002] Bamboo is a renewable and degradable biomass material, which can generally grow into mature bamboo in 4 - 6 years, and has the advantages of being green, environmentally friendly, sustainable, and having good performance. However, the characteristics of the original bamboo, such as its thin-walled and hollow structure, large variability in mechanical properties, and easy corrosion, restrict its wide application in the construction industry. To meet more complex engineering requirements, various new types of bamboo composite materials have been developed by existing processing technologies. Among them, recombined bamboo is a bamboo product that uses bamboo as the main raw material, is rolled into filaments along the grain direction, and then formed through drying, impregnation, assembly, and hot pressing and curing. Recombined bamboo has good mechanical properties, low self-weight, good elastic-plasticity, a strength-to-weight ratio higher than that of wood and concrete, and is easy to be processed into structural components such as beams and columns.

[0003] Due to its excellent physical and mechanical properties, recombined bamboo has broad application prospects in the field of building structures. However, due to the lack of research, recombined bamboo is currently still mainly applied in non-structural application fields such as floors, furniture, and container floors. By proposing a recombined bamboo cable-supported truss structure system, expanding the application of recombined bamboo materials in the building field has broad application prospects in prefabricated bamboo building structures and is of great significance.

The other end of the steel connecting piece 2 is detachably connected to the vertical web member 3 of the main truss. The lower surface of the vertical web member 3 of the main truss is detachably connected to the lower chord 4 of the main truss. Between the upper chord 1 of the main truss and the lower chord 4 of the main truss, there is an inclined web member 5 of the main truss. The inclined web member 5 of the main truss strengthens the stability of the truss. The inclined web member 5 of the main truss is inclined and is located between two vertical web members 3 of the main truss. The number of the upper chords 1 of the main truss is three. Between two upper chords 1 of the main truss, there is an upper chord 6 of the secondary truss. The lower surface of the upper chord 6 of the secondary truss is detachably connected to an inclined web member 8 of the secondary truss. The inclined web member 8 of the secondary truss is inclined. The lower surface of the inclined web member 8 of the secondary truss is detachably connected to a lower chord 7 of the secondary truss. The lower chord 7 of the secondary truss is detachably connected between two lower chords 4 of the main truss.

[0025] The lower surface of the lower chord 4 of the main truss is detachably connected to a strut 16. The strut 16 facilitates the support of the steel cable 17.
