H shaped steel and binding up structure of reinforcing bar

Technical Field

The invention belongs to the field of buildings, and particularly relates to a binding structure of H-shaped steel and reinforcing steel bars.

Background

The top of a building is generally provided with a main beam and a secondary beam, but in the existing structure, the connection of the connection node of the main beam and the secondary beam is not tight enough, and particularly in a large building, the condition of deformation and even fracture easily occurs due to large bearing capacity, so that the building structure is unstable.

Disclosure of Invention

In order to solve the problems, the invention provides a binding structure of H-shaped steel and reinforcing steel bars. According to the invention, the main beam formed by the inner ring beam and the outer ring beam is connected with the oblique beam, and is connected into a whole by the three reinforcing steel bars which are crossed in different directions in a longitudinal and transverse mode, and the reinforcing steel bars are wrapped by the reinforcing mesh formed by the reinforcing steel bars to form a whole, so that the bearing capacity of the connecting node is greatly improved.

In order to achieve the technical effects, the technical scheme of the invention is as follows:

a binding structure of H-shaped steel and reinforcing steel bars comprises an H-shaped inner ring beam and an H-shaped outer ring beam; a V-shaped oblique beam is fixed on the inner side of the inner ring beam; the outer ring beam is fixed with a cantilever beam; a plurality of rib passing holes and rib guiding T-shaped pieces which are uniformly distributed are formed on the inner ring beam, the outer ring beam, the oblique beam and the cantilever beam; radial reinforcing steel bars penetrate through rib passing holes of webs of the inner ring beam and the outer ring beam, and pass through the cantilever beam and the rib guiding T-shaped parts on two sides of the oblique beam; annular steel bars penetrate through the wing plates at the bottoms and the tops of the inner ring beam and the outer ring beam through the rib guiding T-shaped piece; and the outer wrapping steel bars penetrate through the rib guiding T-shaped pieces along the length directions of the cantilever beam, the inclined beam and the top surface and the bottom surface of the cantilever beam.

The curtain wall inhaul cable anchor pipe is fixed on the cantilever beam and connected with one end of a curtain wall inhaul cable, and the other end of the curtain wall inhaul cable is connected with an underground stiff concrete structure.

In a further improvement, an S-shaped keel for installing a curtain wall plate is fixed on the curtain wall inhaul cable.
