Bending member for bamboo reinforced wood beam and manufacture method thereof

Abstract

Provided is a bending member for a bamboo reinforced wood beam. The member is composed of a wood beam, a bamboo board, an adhesive, angular fasteners sand anchor bolts. The bamboo board is closely bonded on the bottom surface of the wood beam through the adhesive. The angular fasteners are arranged on angle positions where the bottom surface intersects with side surfaces of the wood beam along thevertical direction of the wood beam at spaced intervals. Bottom flanges of the angular fasteners are fixed on the bottom surface of the bamboo board. Flanges on the side surfaces of the angular fasteners are fixed on the side surface of the wood beam in order to form a member body. Through the angular fasteners, the reinforced wood board is anchored multiple times. The member enjoys following advantages of effectively preventing separation between the bamboo board and the wood beam, improving anti-bending performance of the wood beam and fully leveraging high anti-pulling strength of the bamboo material.

Description

technical field [0001] The invention relates to a reinforced wooden beam bending member, in particular to a bamboo reinforced wooden beam bending member and a manufacturing method, belonging to the field of civil engineering. Background technique [0002] As an eternal building material, wood is ancient and modern. China is one of the first countries to apply wood structures. Wood has good compression and bending properties. Wood structures have light weight and superior seismic performance. The emergence of modern glued wood structures, It has expanded the application range of wood structures. With the entry of some foreign wood structure production and management enterprises, new technology and new design concepts have been brought in, which has greatly promoted the development of domestic wood structure construction industry. Under humid environment and long-term load, problems such as bearing capacity decrease and deflection increase often occur. [0003] The common rei...

AI Technical Summary

Problems solved by technology

Add iron hoops to strengthen the wooden beams, and the iron parts are easy to rust; under-bracing steel tie rods to reinforce wooden beams are only suitable for beams with small cross-sections, insufficient bearing capacity or excessive deflection, and only when the materials are relatively intact can the fixation of the tie rods be guaranteed. ;The clamping and supporting method has a great influence on the appearance of the components, and is not suitable for architectural wooden beams that have strict requirements on the appearance; only adhesive glue can be used in fiber cloth reinforcement, and there are durability problems under the long-term action of load and environment , and fiber cloth reinforcement generally cannot reinforce the stiffness of components

[0004] At present, the method of using bamboo to strengthen wooden beams has begun to appear in the construction field. For example, Chinese patent "201610463533.2" discloses a method for compositely reinforcing wooden beams. Plates, screwed into circular pins to achieve composite reinforcement of wooden beams, fiber cloth has high strength, high degree of fit, and good deformation coordination, but the setting of the pins will cause certain damage to the bottom of wooden beams, and the cost of fiber cloth high

Another example is the Chinese patent "201010278519.8", which discloses a method for reinforcing wooden beams. Apply primer to the tensioned surface of the wooden beam, then use structural glue to paste at least one layer of bamboo slices on the tensioned surface of the wooden beam, and compact to ensure that the bamboo Bamboo sheets, structural adhesives, and wooden beams are closely combined. This method relies entirely on adhesives to reinforce the material, which will eventually cause peeling damage of bamboo sheets and poor reliability.
