Problems solved by technology

[0004] Bamboo grows rapidly and has excellent materials. It has a long history of processing and utilization in my country. It is an excellent building material. my country is in an international leading position in intensive management, new variety cultivation and new product development. But so far, bamboo is mainly used as wood-based panels. , handicrafts, bamboo-wood composite materials, pulping and papermaking, bamboo charcoal and bamboo vinegar and other fields, there have been researches on using bamboo as engineering materials, such as glued bamboo, etc., but it is difficult to flatten bamboo and need to remove bamboo green and bamboo yellow. and other complex processes, so it has not been effectively used in the field of building structures
If it can be utilized according to the characteristics of the original bamboo structure, it can be used in the field of wood structure construction to replace the standard timber keel of wall materials, roof materials or floor materials in light wood structures, which will help speed up the localization process of wood structure houses , improve people’s living standards, and reduce material costs; in addition, from the perspective of output, my country is already a big country in wood processing. At present, it is basically used as a low-value-added new carbon material for direct combustion and heating, and it has not been effectively used in buildings.

Abstract

The invention discloses a multifunctional bamboo engineering material serving as a light wood structure keel and a preparation method thereof. The bamboo engineering material consists of raw bamboo and a foam material, wherein the foam material is placed inside the raw bamboo; the raw bamboo is arranged between coating panels of a light wood structure wall body material, a roof material or a floor material, and is connected with the coating panels through screws; the diameter of the raw bamboo is matched with the thickness of the wall body material, the roof material or the floor material; the interval of the raw bamboo is set according to the requirement of the mechanical property; gaps formed between the raw bamboo and the coating panels are filled with a heat-insulating and flame-retarding material. The widely-available bamboo in China is applied to a wood structure to replace a keel serving as a specification material of a wall body in a light wood structure, so that the domestication process of wood structure houses is facilitated, the living level of people is raised, and the material cost is reduced.

Description

technical field [0001] The invention relates to the field of wood structures, in particular to a multifunctional bamboo engineering material used as a keel of light wood structures and a preparation method thereof. Background technique [0002] In developed countries and regions typically represented by the United States, Japan, and Canada, wood is a commonly used material for construction, and log structures, light wood structures, and heavy wood structures have always been the mainstream residences of residents in these countries. Among them, the light wood structure is a structural skeleton formed by using closely spaced standard timber as wall studs and wood-based structural panels as cladding panels. The bearing capacity, stiffness and integrity of the structure are obtained through the interaction of primary structural members (framing members) and secondary structural members (wall panels, floor panels and roof panels). Wall studs are mainly constructed of standard t...
