Composite I-shaped beam and method of making the same

Abstract

The invention discloses a combined I-shaped beam and a manufacturing method thereof, wherein the combined I-shaped beam includes light steel, long wooden units, a plurality of first pins, bamboo plywood and a plurality of hoops, and the light steel includes a web, an upper The flange and the lower flange; the left long wooden unit and the right long wooden unit in the long wooden unit are assembled by interlaced lamination of multiple small short woods, and the left long wooden unit and the right long wooden unit are respectively embedded in light steel In the left occlusal cavity and the right occlusal cavity; after the second glue is painted on the outer peripheral surface of multiple first pins, they all penetrate the left long wooden unit, the web and the right long wooden unit embedded in the I-shaped beam base along the left and right direction ; The upper bamboo plywood and the lower bamboo plywood in the bamboo plywood are respectively fixed on the upper surface and the lower surface of the I-shaped beam base part, thereby forming the I-shaped beam structure; a plurality of hoops are set on the I-shaped beam structure on the outer peripheral surface. The combined I-shaped beam of the invention can effectively recycle small-section wood and bamboo resources, has a simple and reliable structure, wide application range and high environmental protection.

Description

technical field [0001] The invention relates to the technical field of building combination, in particular to a combined I-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 small-secti...

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.
