Web frame for concrete organization

Abstract

The present invention relates to a reinforced frame for concrete structure, and belongs to the construction engineering technology. The present invention is characterized in that a steel tube is arranged and small holes are provided on the tube wall of the steel tube. During the process of pouring concrete column, the concrete is combined with the concrete column via small holes on the tube wall to form an integrated body, therefore, the structure has the functions of high pressure resistance, high shearing resistance, and high torque and vibration resistance, and the present invention has the advantages of simple structure, acceleration of construction progress, saving raw materials and labor forces, being not affected by climate and temperature, being fireproof, being aging and corrosion resistant, and extending service life.

Description

technical field [0001] The invention relates to concrete structures in the technical field of construction engineering, in particular to a reinforced skeleton for concrete structures. Background technique [0002] We know that reinforced concrete structures and steel pipe concrete structures have been used in buildings, bridges and other projects for many years. The reinforced concrete structure uses longitudinal steel bars and transverse steel bars bound into a steel cage (net) to serve as the skeleton of the concrete structure. This concrete structure provides good resistance to compression (tension), shear force, torsion, etc. The structure requires at least three processes: one is to cut and bend the steel bars; the other is to bind the cut or bent steel bars into a steel cage (net); the third is to transport and install the tied steel cage (net). All three processes require a lot of labor and time. The steel pipe concrete structure uses steel pipes as the skeleton in ...

Problems solved by technology

However, the CFST structure has two major weaknesses: one is that the steel pipes in this structure are exposed to the outside of the concrete, and the steel pipes need to be protected against rust and fire; , the thermal expansion and contraction coefficients of steel pipe and concrete are different. After a certain number of repeated heat and cold changes, gaps will appear between the steel pipe and concrete. At this time, it is difficult for the two to work together to resist pressure, which affects the quality of the project. caused great danger
