What Is a Wood Beam?
A wooden beam is supported by a bearing. The external force that it bears is mainly transverse and shear forces. The component that deforms mainly by bending is called a beam. A wooden beam is one of the beams classified by material. Wooden beams are widely used in ancient buildings. In modern buildings, wooden floors and wooden beams are used to decorate the home. There is no luxurious decoration, and it is simple and plain.
- Although there are many advantages to using wooden structures in buildings, there are still many disadvantages. For example, the construction progress is tight, it is difficult to control the moisture content in wooden materials, and the wooden members often rot and crack during use. If a large amount of high-quality wood is used and the corresponding measures are used to dry the water contained in the wood, the cost of construction will be increased, and the wood does not have good fire resistance. Therefore, it is rarely used in antique buildings. Wood structure. After the continuous development of the construction industry and the continuous exploration of building materials and processes, concrete structures have become more and more widely used in current building construction due to the advantages of simple construction, convenient and fast connection, and strong durability and safety. . At present, in the construction of antique buildings, the combination application mode of wood structure and concrete structure is more adopted. The main frame of the building, such as gold pillars, beams, and roofing, generally adopts a concrete frame structure.The visible parts such as eaves, railings, exterior doors and windows, and bucket arches are made of wooden structures. Only then can it be renovated. Adopting such a combination to integrate the two structures can promote strengths and avoid weaknesses.On the one hand, it can save wood, so that the cost of the project is reduced, and the building can have better fire resistance and durability. It is also conducive to maintaining the traditional architectural style. [1]
- Although the application of the combination of wood and concrete structures in antique buildings can save materials, reduce costs and enhance safety and durability, the connection between the currently used wooden members and concrete still has no specifications and design standards for our reference. Therefore, we need to pay more attention to the safety and reliability of nodes. The following introduces several traditional concrete column and wooden beam connection technologies.
- Glued Laminated Timber (Glulam for short) is an engineered wood product classified according to the strength of the wood. According to the performance characteristics of the single-layer board, it is arranged in different positions and then glued together with a highly durable adhesive to form of. Through the production of glued wood, the short materials after cutting operations and wood processing, as well as the small-diameter timbers planted and thinned by artificial forests can be spliced, laminated, and glued, and shortened to long, narrow to wide, and thin to thick. Glulam can be optimized by using different grades of laminates according to the needs, effectively avoiding the defects of the logs, achieving the best use of inferior materials, and making the components have higher strength and durability.
