Description

Technical Field

[0001] The utility model relates to the technical field of bridge pre-embedded joints, in particular to a bridge pre-embedded connection structure based on BIM technology. Background Art

[0002] BIM building information model is convenient for all parties involved in the project. When using it, the distribution cables need to be protected by the installation of bridges. In the project's residential and office main buildings, each floor is equipped with a distribution well, and the distribution wells on each floor are in a unified position. There are several busbars and cable bridges in the distribution well. Due to the limited space in the distribution well and the need to pass through the floor slab for laying, the cable bridge is usually installed along the shaft. The traditional method of installing the cable bridge is: before construction, prepare foam blocks of appropriate size or use templates to nail rectangular wooden boxes to make a mold for the reserved bridge opening, and fix the mold on the template before pouring the floor concrete. After the concrete solidifies, remove the mold of the reserved opening. It mainly includes the following steps: determine the size of the reserved opening - make a mold according to the size of the reserved hole - fix the mold on the template - pour concrete - remove the template - clean the opening - install the bridge - lay wires and cables - cover the bridge cover - fireproof sealing of the opening.

[0003] The above-mentioned cable bridge installation method along the shaft has the following main shortcomings: 1. The reserved hole mold is made of foam board or wood board, which needs to be removed separately after pouring concrete. The operation is cumbersome and increases the construction cost, generates a large amount of construction waste, and the foam board also pollutes the construction site environment. 2. The bridge hole also needs to be suspended and filled with fine stone concrete for fireproof blocking, especially the position of the bridge cover, which is difficult to handle. Based on this, it is necessary to provide a bridge pre-buried structure that is easy to install and does not require the demoulding procedure after pouring concrete. Utility Model Content
