Sleeve connection device and construction method for lightning protection and grounding of structural steel bars in industrialized buildings

Abstract

The invention provides a sleeve connecting device with lightningproof grounding structure steel bars in industrial building. The sleeve connecting device comprises a grouting sleeve, a structure steel bar A, a structure steel bar B and a lightningproof connecting mechanism, wherein one end of the grouting sleeve is connected with one end of the structure steel bar A; the grouting sleeve and the structure steel bar A are embedded in a structure component A; the structure steel bar B is embedded in a structure component B; one end of the structure steel bar B extends out of the end surface of the structure component B; and the grouting sleeve is connected with the structural steel bar B through the lightningproof connecting mechanism. The construction method of the sleeve connecting device comprises the following steps of: processing the grouting sleeve; prefabricating the structure component A and the structure component B; processing the lightningproof connecting mechanism; connecting the lightningproof connecting mechanism into the grouting sleeve; hanging the structure component A and the structure component B in place; and completing the grouting. The structure steel bar A in the sleeve connecting device sequentially passes through the grouting sleeve and the lightningproof connecting structure to form a lightningproof conduction path with the structure steel bar B, so that the goal of using the structural steel bars of a vertical component in an assembled concrete structure as a lightningproof grounding downlead is achieved.

Description

technical field [0001] The invention relates to the fields of structural engineering and electrical engineering, in particular to a sleeve connection device and construction method for lightning protection and grounding of structural steel bars in industrialized buildings. Background technique [0002] my country's construction industry has always been in the traditional industrial stage of labor-intensive and relatively backward construction methods; in the construction and use of houses, the traditional construction mode of high energy consumption, high pollution, low efficiency and roughness is universal, which is different from the current new Urbanization, industrialization, and informatization do not meet the development requirements, and there is a big gap with developed countries; the contradiction between urban and rural construction and environmental resource constraints is becoming increasingly prominent. Therefore, under the national conditions of sustained and ra...

Problems solved by technology

The important assembly and connection method of the vertical structural members of the prefabricated concrete structure is the steel sleeve grouting connection, but in order to ensure the reliability of the steel sleeve grouting connection and the adjustability of the length of the installed steel bar, the sleeve grouting is required according to the mechanical properties and specifications. There is a certain distance between the structural reinforcement at the end and the inner wall of the sleeve, so the upper and lower structural reinforcement in the vertical structural member cannot form a conductive path, so the prefabricated concrete structure cannot use the vertical main structural reinforcement as the traditional cast-in-place concrete structure.
