Combined T-shaped beam and manufacturing method thereof

Abstract

The invention discloses a combined T-shaped beam and a manufacturing method thereof. The combined T-shaped beam comprises light steel, long wood units, a plurality of first pins, bamboo plywood and a plurality of hoops; the light steel comprises a web plate, an upper flange and a lower flange; a left long wood unit and a right long wood unit in the long wood units are formed by splicing a plurality of small short woods in a staggered and laminated mode, and the left long wood unit and the right long wood unit are respectively embedded and fixed in a left occlusion cavity and a right occlusion cavity of the light steel; the peripheral surfaces of the plurality of first pins are coated with second adhesive and then are embedded into the left long wood unit, the web plate and the right long wood unit of the T-shaped beam base part in a penetrating mode in the left-right direction; the upper bamboo plywood and the lower bamboo plywood in the bamboo plywood are correspondingly fixed on the upper surface and the lower surface of the T-shaped beam base part respectively, so that a T-shaped beam structure is formed; and the plurality of hoops are arranged on the peripheral surface of the T-shaped beam structure in a sleeving mode. According to the combined T-shaped beam, small-section wood and bamboo resources can be effectively recycled, and the combined T-shaped beam is simple and reliable in structure, wide in application range and high in environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of building composite structures, in particular to a composite T-shaped beam and a manufacturing method thereof. Background technique [0002] In the building structure of villages and towns, brick-wood structure and wood frame structure are widely used. Wooden beams are horizontal components of brick-wood structure and wood frame structure. In the brick-wood structure, wooden beams can be directly placed on the brick wall to bear the load of the floor or roof, and transfer the load to the brick wall; The borne floor or roof loads are transmitted to the wooden columns through the nodes. [0003] Traditional wooden beams are usually made of whole logs with circular and rectangular cross-sections. Due to excessive deforestation, the resources of whole logs with large cross-sections are very scarce. On the other hand, there are more stocks of abandoned small-section logs sawn off in the forest and remaining s...

Problems solved by technology

However, the mechanical properties of bamboo are closely related to its moisture content, bamboo stalk position, bamboo age, site conditions and bamboo species, and there are great differences, which limits the wide application of bamboo in construction.
