Environment friendly H-shaped combination beam and processing method thereof

Abstract

The invention discloses an environment friendly H-shaped combination beam, which is characterized by comprising wood or bamboo main web plate and two [ shaped groove profile steel plates, the web plates of the groove profile steel plates are fixedly arranged on the sides of the main web plate, the upper end of the main web plate is fixedly provided with a wood or bamboo upper main flange, the upper end face of the upper flange of the groove profile steel plates is fixedly connected with the lower end face of upper main flange, the lower end of the main web plate is fixedly provided with a wood or bamboo lower main flange, and the lower end face of the lower flange of the profile steel plates is fixedly connected with the upper end face of the lower main flange. The invention has the advantages that the combination of steel plate and wood or bamboo plate replaces with traditional reinforced concrete material for the combination beam, thus reducing self weight of traditional beams and pillars, enhancing shock resistance of buildings using the combination beam, ensuring the combination beam to have higher bearing capacity and rigidity due to good load-carrying property of wood or bamboo wares, and reducing cost and pollution.

Description

technical field [0001] The invention relates to a beam and column structure in civil engineering, in particular to an environment-friendly I-shaped composite beam and a processing method thereof. Background technique [0002] In the field of civil engineering, the current common beam and column components are generally made of reinforced concrete materials. Its self-heavy weight makes the self-weight of the entire building relatively large, and the greater the self-weight of the building, the more unfavorable it is for earthquake resistance; and According to statistics, 0.8 tons of carbon dioxide is emitted for every ton of cement fired. In addition, steel consumes a lot of energy in the production process and emits a lot of waste water, solid waste and waste gas pollutants. It can be seen that the use of Reinforced concrete materials are used to make beams and columns, which has a low resource utilization rate and a large environmental load.

[0003] The application date is May 11, 2009, and the application number is CN200910098446.1, which discloses a combined I-beam in the publication specification of the Chinese invention patent application, which is characterized in that it includes an I-shaped steel frame, and the web of the steel frame is fixed on both sides. A first bamboo board or a first wooden board is provided, and at least one of the upper and lower surfaces of the upper flange of the steel frame is fixed with a second bamboo board or a second wooden board. , At least one of the lower two surfaces is fixed with a third bamboo board or a third wooden board; since the I-shaped steel frame in the composite beam is integrally formed, the amount of steel used is relatively large, and the bamboo board in this structure Or the utilization rate of wood boards is not high, and the mechanical properties of bamboo / wood boards cannot be fully utilized
