Embodiment Construction

[0026] Such as figure 1 Shown, masonry structure transformation method of the present invention comprises the steps:

[0027] (10) Reinforced structural column: the structural column at both ends of the wall to be demolished is reinforced with a lattice column, and the lower end of the lattice column is in close contact with the foundation;

[0028] (20) Underpinning beams are set: steel box girders are set on both sides of the wall ring beam to be demolished, and the two ends of the steel box girder are fixedly connected with the lattice columns at the two ends of the wall to be demolished respectively, and the sides of the steel box girder are connected with the lattice columns to be demolished. Demolition wall ring beam fixed connection;

[0029] (30) Demolition of masonry walls: remove the wall to be demolished under the ring beam.

[0030] As an improvement, before the step (30) of removing the masonry wall, it also includes the step of connecting the steel box girders ...

Abstract

The invention discloses a masonry structure transformation method and an underpinning structure for masonry structure transformation. The transformation method includes the steps that (10) constructional columns are reinforced, i.e., the constructional columns at the two ends of a wall to be demolished are reinforced with latticed columns, and the lower ends of the latticed columns are in tight contact with a foundation; (20) underpinning beams are arranged, steel box beams are arranged on the two sides of ring beams of the wall to be demolished, the two ends of each steel box beam are fixedly connected with the latticed columns at the two ends of the wall to be demolished correspondingly, and the side faces of the steel box beams are fixedly connected with the ring beams of the wall to be demolished; and (30) the masonry work wall is demolished, i.e., a wall body to be demolished under the ring beams is demolished. The underpinning structure comprises the latticed columns (1) and the steel box beams (2), the latticed columns are arranged around the constructional columns (4) at the two ends of the wall to be demolished (3) in a reinforcing mode, the steel box beams (2) are arranged on the two sides of the ring beams (5) of the wall to be demolished, the two ends of each steel box beam (2) are fixedly connected with the latticed columns (4) at the two ends of the wall to be demolished (3) correspondingly, and the side faces of the steel box beams (4) are fixedly connected with the ring beams (5) of the wall to be demolished. According to the masonry structure transformation method and the underpinning structure for masonry structure transformation, construction is simple, and investment is little.

Description

technical field [0001] The invention belongs to the technical field of construction engineering transformation, in particular to a method for transforming a masonry structure into a frame structure and an underpinning structure, and is especially suitable for transforming small offices and dormitories with masonry structures into large-space and large-area residences and In the case of public buildings. Background technique [0002] At present, there are a large number of masonry structures that have been built and put into use in my country. However, due to the long time of use and the limitations of the economic and technical conditions at that time, in addition to quality problems, this type of building gradually revealed that it could not adapt to the changes in use and function brought about by economic development and the improvement of people's living standards. Reinforcement and transformation of the original masonry buildings is the main way to solve this problem. ...
