Description

Ribbed lightweight steel beam with a new connection method

technical field

The utility model relates to the field of structural engineering, in particular to a ribbed light-weight steel beam with a novel connection method.

Background technique

Beam is a building structure, supported by supports, the external force is mainly lateral force and shear force, and it is the main load-bearing structure of the building.

In terms of function, there are structural beams, such as foundation ground beams, frame beams, etc., which together with vertical components such as columns and load-bearing walls form a spatial structure system; there are structural beams, such as ring beams, lintels, connecting beams, etc. To crack resistance, earthquake resistance, stability and other structural effects.

Concrete is made by mixing cement, sand, stone and water, admixture materials and admixtures in a certain proportion. After solidification, it is as hard as stone, with good compressive ability, but poor tensile ability, and is easy to break due to tension. In order to solve this contradiction and give full play to the compressive capacity of concrete, a certain number of steel bars are often added in the tensile area of concrete or corresponding parts, so that the two materials can be bonded into a whole and bear external forces together. This type of concrete with reinforcement is called reinforced concrete.

Traditional reinforced concrete beams have problems such as self-heavy, non-tensile concrete, brittle nature, and prone to cracks. Therefore, in view of the excellent tensile and compressive properties of steel, lightweight steel beam structures have appeared in recent years.

The steel beam design in the prior art has the following problems:

1. The strength is not high enough, and sometimes it cannot meet the load-bearing requirements;

2. The utilization rate of steel is not high enough, resulting in unnecessary waste.

Therefore, the utility model proposes a ribbed light-weight steel beam with a novel connection method.

The utility model adopts the following technical scheme:

A ribbed light-weight steel beam with a new connection method is characterized in that it is composed of a wedge-shaped outer frame body, a cross inner support rib and a column body that fits the wedge-shaped beam, and the frame body includes a top plate, a side plate and a bottom plate. The cross inner support rib includes transverse ribs and vertical ribs, and the wedge-shaped outer frame and the cross inner support rib extend along the length direction of the steel beam.

Preferably, in the ribbed light-weight steel beam of the novel connection method, the cross-sectional shape of the steel beam is wedge-shaped.

Preferably, the ribbed light-weight steel beam of the new connection method adopts the method of adding a plurality of cross inner support ribs in the outer frame body.

Preferably, for the ribbed light-weight steel beam of the new connection method, the connection form between the wedge beam and the column is a tenon-and-mortise structure.

Preferably, the ribbed light-weight steel beam of the new connection method, if it is desired to further enhance the reliability of the beam in the project, and when the conditions are met, the method of injecting concrete into the wedge-shaped beam can be adopted to make a concrete-filled steel tube beam .

The beneficial effects of the utility model are: (1) The ribbed light-weight high-strength steel beam adopts a wedge-shaped section, which can effectively improve the utilization rate of materials. (2) After adding the cross inner support rib to the wedge-shaped outer frame body, the bending and shearing strength of the steel beam is greatly increased. (3) The connection between the steel beam and the column is tenon and mortise connection, and the connection is more reliable. (4) The light-weight steel beam can be injected with concrete when necessary to make a concrete-filled steel tube beam to improve the strength level. The ribbed light-weight high-strength steel beam can effectively strengthen the strength of the beam, increase the utilization rate of materials, increase the reliability of the connection between the beam and the column, and has simple construction and wide application.
