A lightning protection downconductor connection structure and its construction method in a prefabricated building

Abstract

The invention discloses a connection structure for lightning protection down conductors in a prefabricated building and a construction method thereof. The upper connecting piece on the upper steel bar and above the grouting sleeve, the lower connecting piece connected to the lower steel bar and below the grouting sleeve, the upper reserved plate connected to the outer side of the upper connecting piece, and the lower connecting piece connected to the outer side of the lower connecting piece The lower reserved plate; the lead piece connected between the upper reserved plate and the lower reserved plate; the outer surface of the upper reserved plate and the lower reserved plate is flush with the outer surface of the column where it is located. The present invention not only facilitates the pre-connection but also ensures the connection fastness when pouring the grouting material by setting the upper connecting piece and the lower connecting piece; the U-shaped design of the upper connecting piece and the lower connecting piece can ensure the fastening of the connection; The setting of the upper reserve plate and the lower reserve plate is beneficial to the assembly construction; through the setting of the lead parts, it is convenient for backup maintenance during diversion and strengthening application.

Description

A lightning protection down-conductor connection structure in a prefabricated building and its construction method technical field The invention belongs to the field of prefabricated building construction, particularly relate to a lightning protection down-conductor connection junction in a prefabricated building structure and its construction method. Background technique At this stage, prefabricated buildings are developing vigorously and rapidly, and various prefabricated components appear in large numbers. Among them, prefabricated prefabricated concrete The construction of the soil frame column makes the upper and lower layers of the steel frame in the frame column isolated by the grouting material, which cannot be effectively electrically connected, and is connected to the lightning protection. The system presents a problem. In the conventional electrical design, the lightning protection down-conductor uses the steel bar in the concrete column as the down-conduc...
