Problems solved by technology

[0005] The disadvantage of the above two solutions is that the contact area between the metal shrapnel or the conductive sleeve and the grouting sleeve is limited. After grouting, the grout will enter the contact position between the metal shrapnel or the conductive sleeve and the grouting sleeve, making the electrical conduction unstable

Abstract

The invention discloses a sleeve connection device for lightning protection and grounding of prefabricated buildings. The connection device comprises an upper reinforcement structure, a grouting sleeve and a lower reinforcement structure, one end of the upper reinforcement structure is connected with one end of the grouting sleeve, the sleeve connection device further comprises a connecting pieceextending into one end of the grouting sleeve away from the upper reinforcement structure, the connecting piece sleeves the lower reinforcement structure, and a conductive medium is filled between theconnecting piece and the grouting sleeve. The invention also discloses a construction method. The construction method comprises the following steps that (1) the end of the upper reinforcement structure is connected with the end of the grouting sleeve; (2) the connecting piece sleeves the lower reinforcement structure, and the connecting piece is connected with the grouting sleeve; (3) the conductive medium is filled between the connecting piece and the grouting sleeve; and (4) the grouting sleeve is grouted. Through filling the conductive medium between the connecting piece and the grouting sleeve, the conductive contact area of the connecting piece and the grouting sleeve is increased, and stable electrical conduction between the upper reinforcement structure and the lower reinforcementstructure is ensured.

Description

technical field [0001] The invention relates to the technical field of building lightning protection, in particular to a sleeve connection device and a construction method for a prefabricated building lightning protection grounding. Background technique [0002] For prefabricated concrete buildings, it is characterized by standardized production in factories and integrated assembly and molding on site. When the vertical member is prefabricated, the connection method of the steel bars in the vertical member is mainly in the form of sleeve grouting, the upper and lower steel bars are disconnected in the sleeve, and the sleeve grouting process makes the upper and lower steel bars blocked by the grouting material. Electrical penetration cannot be formed, so it is difficult to use its internal steel bars as lightning protection downconductors like traditional cast-in-place concrete vertical members. [0003] The existing solution is to add conductive parts in the grouting sleeve...
