The invention provides a formwork construction method for repairing and transforming reinforced concrete buildings of historical industrial buildings. First, the girders at the bottom of the historical beams are poured, and the girders extend to the outside of the preserved historical beams, and wooden mold cavity boxes are pre-embedded at the bottom of the girders. The mold cavity box is fixed by scaffolding, and horizontal construction joints are set on the top of the beam support; a steel frame is set on the beam support on the side of the preserved historical beam, and the steel frame is close to the preserved historical beam; the formwork is installed; the upper part of the new beam is constructed Floor reinforcement; integral pouring of floor and new beams; removal of formwork and scaffolding. The present invention successfully solves the problem of retaining historical beams by first setting the beam support at the bottom of the historically preserved beam, pre-burying a wooden mold cavity box at the bottom of the beam support, setting a steel bar frame on the beam support, and then integrally pouring the floor slab and the new beam. Construction problems of new beams under conditions.
Description
Technical field [0001] The invention belongs to the field of civil engineering, in particular to mold construction in a historical industrial buildings of reinforced concrete building repair transformation. Background technique [0002] In some major cities in our country still retains some historical old industrial buildings of reinforced concrete buildings, many of these historic buildings are relying on the construction of industrial buildings Westerners Reinforced Concrete restoration and improvement of the plant, already has a heritage value. Because these built in reinforced concrete structures hundred years ago, its strength, rigidity can not meet the requirements of the new structure of the building shall be repaired rehabilitation in order to retain and enhance the heritage value. However, new construction and renovation renovation project there are many differences, specific to the project template is quite different. The original building has a concrete structure only ...
