Reinforcing method and reinforcing structure of improvement of original construction floor structure

Abstract

The invention discloses a reinforcing method and a reinforcing structure of an improvement of an original construction floor structure. Reverse arm beams are additionally arranged among original pillar net structures of an original building. Overhead layers are arranged between the reversed arm beams and the original construction floor structure. The reverse arm beams are connected with the original pillar net structures by planting rebars. And then non-adhesion prestress base plate construction is performed on the reverse arm beams. Loads of horizontal components of the original structure are transferred to the additionally arranged structures so as to reduce stress levels of the original structure and reduce deformation of the original structure. The width of a fracture is narrower and even zero. A complete load bearing structure system is formed by additionally arranged beam plates so as to effectively change use functions of the building. Pipes and lines are convenient to lay in the overhead layer so as to increase an effective use space. As reinforcement construction is performed on the floor of variated functions, daily use of the original building is not affected.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a reinforcement method and a reinforcement structure for the reconstruction of existing building floor structures. Background technique [0002] In recent years, with the development of our country's economy, the upsurge of existing building structure transformation is in the ascendant. For existing buildings, it is often necessary to change the use function of the floor, and the bearing capacity of the existing structure often cannot meet the needs after the function change. In this case, appropriate structural reinforcement and reconstruction measures must be taken. For example, when it is necessary to add a bathing center in a high-rise building, since the design value of the vertical load on the floor of the bathing pool center is usually 2 to 3 times that of the floor of a normal public building, appropriate reinforcement measures must be taken. satisfy. [0003] However...

Problems solved by technology

[0004] The technical problem to be solved by this invention is to overcome the defect that the construction of the existing conventional reinforcement method will affect the normal use of the building, and to provide a reinforcement method for the transformation of the existing building floor structure, which is suitable for changing the existing building floor into a bath, data The function change of room and other load increases greatly, while meeting the requirements of functional transformation, it does not affect the normal use of each floor of the existing building
