The invention discloses a construction technology for reinforcing a ledger beam through angle iron. The construction technology for reinforcing comprises the following steps that 1, a formwork is manufactured, wherein an angle iron formwork is manufactured according to the angle between the ledger beam and a plate on site; 2, angle iron is machined, wherein the formwork is conveyed to a machiningfactory, and the angle iron is machined according to the fixed length of the formwork; 3, an original concrete surface is cleaned and polished, wherein the concrete surface is polished at the angle iron adhesion part by using a polishing machine, and cleaned and scrubbed by using acetone; 4, setting-out is conducted, wherein setting-out is conducted at the angle iron adhesion part so as to guarantee the subsequent construction quality; 5, hole drilling, assembling and welding, and angle iron roughening treatment are conducted; 7, the angle iron is adhered; 8, chemical anchor bolts are installed; and 9, antirust and fireproof paint is brushed on the surface of the angle iron. According to the angle iron reinforcing construction technology for the ledger beam, the bent angle iron is tightlyconnected with structural adhesives and an original concrete beam, so that the overall stress of the structure is guaranteed, the adhesive steel adhesives bear shearing force, bolts are used as assistance, the purposes of increasing the supporting length of a pre-supported floor slab and effectively improving the rigidity of the floor slab can be completely achieved, and good market prospects areachieved.
