Damage-free steel beam reinforced concrete frame and construction method thereof

Abstract

The invention discloses a damage-free steel beam reinforced concrete frame and a construction method thereof. The damage-free steel beam reinforced concrete frame comprises steel clamping plates, thesteel clamping plates comprise an upper steel clamping plate, a middle steel clamping plate and a lower steel clamping plate, the upper steel clamping plate and the lower steel clamping plate are thesame in structure and correspondingly correspond to a flange connecting area of a steel beam, and the middle steel clamping plate corresponds to a web of the steel beam; the upper steel clamping platecomprises two steel plates, and the two steel plates are fixed to reinforced concrete columns through long screws on the two sides. The U-shaped middle steel clamping plates are fixed to the reinforced concrete columns through adhesives, outward-extending steel plates are arranged on the sides, close to the steel beam, of the upper steel clamping plates, the middle steel clamping plates and the lower steel clamping plates, and the outward-extending steel plates of the upper steel clamping plate and the lower steel clamping plate are connected with upper and lower flanges of the steel beam through connecting steel plates. The outwards-extending steel plate of the middle steel clamping plate is directly connected with the web of the steel beam. According to the damage-free steel beam reinforced concrete frame and the construction method thereof, the integrity of the columns during reinforcing of the reinforced concrete frame is enhanced, and the damage-free steel beam reinforced concrete frame has wide application prospects in reinforced concrete structure buildings.

Description

technical field [0001] The invention relates to the technical field of node connections in building structures, in particular to a frame and a construction method for reinforcing reinforced concrete with non-damaged steel beams. Background technique [0002] In reinforced concrete building structures such as industrial plants, in order to cope with the increase in load caused by the arrangement of machinery and equipment and production materials under process transformation, it is necessary to strengthen the reinforced concrete building structure. It is an effective reinforcement measure to add steel beams under the reinforced concrete beams and use the steel beams to bear the increased load and transmit it to the columns. However, the connection between steel beams and reinforced concrete columns often adopts the method of perforating the columns and tightening them with bolts, which will cause damage to the reinforced concrete columns; if there are too many joint bolts, th...

Problems solved by technology

However, the connection between the steel beam and the reinforced concrete column is often used to perforate the column and tighten it with bolts, which will cause damage to the reinforced concrete column; if there are too many node bolts, it will even cause the reinforced concrete column to lose its performance.
