Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. For the convenience of description, the "up" and "down" described below are consistent with the directions of up and down in the drawings, but this should not be a limitation of the technical solution of the present invention.
[0024] The existing structure replacement project in this embodiment takes a brick-wood mixed structure building as an example. The brick wall 2 is used as the partition of the internal space. The thickness of the brick wall 2 is generally 240mm. Figure 1 to Figure 14 Illustrate the transformation method of existing structure replacement concrete system of the present invention, concrete steps ar...

The invention discloses a transformation method for replacing an existing structure with a concrete system, and relates to the technical field of existing building structure transformation. Hardly no research on a construction method for replacing / transforming the existing structure with / into a concrete structure is available, and the actual requirement of existing structure transformation engineering cannot be met. The method comprises the following steps that a structure replacement construction area is divided into an early-stage construction area and a later-stage construction area through an internal brick wall of the existing structure, then each structure replacement construction area is averagely divided into a plurality of long-strip-shaped construction blocks, and wood structure floor slabs and wood structure beams of each construction block are replaced through a jump warehouse method; and the wood structure floor slabs and the wood structure beams in the early-stage construction area are sequentially dismantled, then the wood structure floor slabs and the wood structure beams in the later-stage construction area are sequentially dismantled, and concrete floor slabs and reinforcing beams are poured in the corresponding construction areas on the two sides of the brick wall and are connected into a whole, so that the existing structure is safely and efficiently replaced with the concrete system.
Description
technical field [0001] The invention relates to the technical field of reconstruction of existing building structures, in particular to a reconstruction method for replacing a concrete system with an existing structure. Background technique [0002] In recent years, with the continuous advancement of the urbanization process, the renovation projects of old buildings are increasing day by day. Among them, the renovation projects of historically protected buildings also account for a considerable proportion. The influence of the appearance of the building, but also to make the reconstructed structure meet higher bearing capacity requirements, thus increasing the difficulty of construction. [0003] At present, most of the historically protected buildings are of brick-wood mixed structure. Generally, wooden floor slabs are used, wooden beams are arranged below them, and brick walls are used to vertically separate the internal space. It is greatly affected by the environment, a...
