Abstract

The utility model discloses a steel plate reinforced box type wood beam with bamboo webs, which comprises an upper wood member 1-1, a lower wood member 1-2, a left wood member 1-3 and a right wood member 1-4 along the beam length direction; a bamboo web 2 arranged vertically to the upper and lower wood members; and a reinforced steel plate 3 disposed under the lower wood member 1-2. The advantages are that: the box wooden beam of steel sheet reinforcing area bamboo web, the mill can the modularization production with prefabricated, the equipment is also convenient and fast, is a green's structural component. Compared with the common box-type wood beam, the steel plate reinforced box-type wood beam with the bamboo web plate has the advantages that: the shear strength, the bending resistance bearing capacity, the strength-to-weight ratio, the strength utilization rate and the like are all improved.

Description

Box-type wood beam with bamboo web plate reinforced by steel plate

Technical Field

The utility model relates to a civil engineering structure field especially relates to a steel sheet reinforcing bamboo wood composite box roof beam.

Background

Wooden structure technique is more and more being paid close attention to at home and abroad, and traditional wooden component is a green's structural component, has the characteristics of light weight height, and wooden case roof beam can realize modular production and prefabrication in the mill to simple to operate is swift, and the time limit for a project is short. But the strength utilization rate and the mechanical performance indexes such as shear strength, bending strength and the like are not ideal.

China's fast growing wood (poplar, pine, eucalyptus, etc.) and bamboo resources are quite rich, and meanwhile, various steels have higher tensile strength. If local wood and bamboo resources can be fully utilized to produce the heavy steel plate reinforced box-type wood beam with the bamboo web, the product has better mechanical property, and meanwhile, due to abundant resources, the cost performance of the heavy steel plate reinforced box-type wood beam is possibly more advantageous than that of a foreign pure wood structure.

Disclosure of Invention

The purpose of the invention is as follows: to the not enough of existence among the prior art, the utility model aims at providing a box wooden beam of steel sheet reinforcing area bamboo web has advantages such as environmental protection level height, light high strength, high, the shear strength of intensity utilization ratio height of excelling in.

The technical scheme is as follows: in order to achieve the above purpose, the technical solution adopted by the present invention is as follows: a steel plate reinforced box-type wooden beam with bamboo web is composed of box beam made of wood, box beam web made of bamboo, and steel plate with proper thickness under the box beam and made of epoxy resin adhesive.

Has the advantages that: the utility model discloses a box wooden beam of steel sheet reinforcing area bamboo web had both remain the basic advantage of traditional box wooden beam, can exert respectively again and constitute the component material advantage: the bamboo material has good shearing resistance, and the bamboo specification material is arranged in the middle of the component, so that the shearing resistance of the component can be improved; the steel plate has higher tensile strength, and the bending resistance bearing capacity, the strength utilization rate and the strength-to-weight ratio of the member can be improved by arranging the steel plate at the lower part of the lower wood member.

Detailed Description

The present invention will be further described with reference to the following specific examples.

As shown in figure 1, the main structural components of the box-type wood beam with the bamboo web plate reinforced by the steel plate comprise an upper wood member (1-1), a lower wood member (1-2), a left wood member (1-3) and a right wood member (1-4) along the length direction of the beam; a bamboo web plate (2) which is vertically arranged with the upper wood and the lower wood; and a reinforced steel plate (3) disposed under the lower wood member.

The box-type wood beam with the bamboo web plate is manufactured by firstly flatly placing a reinforced steel plate (3), then placing lower wood members (1-2) with the same size above the reinforced steel plate (3), gluing the lower wood members and the reinforced steel plate by adopting epoxy resin structural adhesive, vertically installing the bamboo web plate (2), the left wood members (1-3) and the right wood members (1-4) on the upper surface of the lower wood members (1-2), gluing the lower wood members and the left wood members by adopting epoxy resin structural adhesive, then splicing the upper wood members (1-1) above the bamboo web plate (2), the left wood members (1-3) and the right wood members (1-4), gluing the upper wood members by adopting epoxy resin structural adhesive, and finally pressing the members by using a press.

The utility model discloses a bamboo, wood, steel sheet veneer are connected, and the advantage lies in: the utility model discloses a box wooden beam of steel sheet reinforcing area bamboo web has overcome the shortcoming that shear strength is low and intensity utilization is low in the aspect of traditional box wooden beam goods mechanical properties, and the advantage of the different material mechanical properties of each component of make full use of has higher bending resistance bearing capacity and weight ratio, has improved the anti-shear bearing capacity of intensity utilization and component.
