Currently, to prevent lightning stroke, lightning surge intrusion and thunder and lightning electromagnetism from rushing the destruction to building and people's lives safety,
Most of buildings are all in accordance with lightning protection device.Usually made using two elongated main reinforcements in the reinforced column or shear wall of building
For downlead, but prefabrication uses factory-made component, the form of construction work of on-site consolidation, upper and lower level reinforcing bar at present
Connection mostly uses grout sleeve to connect greatly, and this connection type prevents upper and lower level main reinforcement from being electrically connected, and is unsatisfactory for preventing
The condition of thunder downlead.
The two kinds of lightning protection downlead modes introduced in Chinese patent ZL201721229932.9 and ZL201820302491.9,
Its application operability is poor, and site operation is cumbersome, therefore haves the defects that poor for applicability.
Summary of the invention
It is an object of the present invention to provide a kind of new prefabricated assembled concretes to build lightning protection downlead connection method and construction,
Solve that existing full-prefabricated assembled concrete structure grout sleeve mounting process is not perfect to lead to upper and lower level prefabricated post main reinforcement not
The problem of capable of being electrically connected.
The present invention is achieved by the following technical scheme:
A kind of prefabricated assembled concrete building lightning protection downlead connecting structure, including upper precast construction column and lower precast construction
Column, the lower precast construction capital face protrude lower precast construction column main reinforcement；The upper precast construction column bottom surface is located at its every
Upper precast construction column main reinforcement position is reserved with grout sleeve mounting hole, and every upper precast construction column main reinforcement lower end a part is accordingly stretched
Enter grout sleeve mounting hole；Grout sleeve is placed in the grout sleeve mounting hole；Main reinforcement up and down is set in the grout sleeve
Connection component, the main reinforcement connection component up and down include the high strong spring positioned at middle part, and the high-strength both ends of the spring is welded and fixed
There are upper spherical claw and lower spherical claw；The upper precast construction column main reinforcement is fixedly connected with the arm end of upper metal connecting piece, institute
The ball side pressure for stating metal connecting piece enters upper spherical claw；The arm end of the lower precast construction column main reinforcement and lower metal connecting piece is solid
Fixed connection, the ball side pressure of the lower metal connecting piece enter lower spherical claw.
Above-mentioned prefabricated assembled concrete builds lightning protection downlead connection method, as follows:
Upper precast construction column main reinforcement and the arm end of upper metal connecting piece using welding or are bolted；
Lower precast construction column main reinforcement and the arm end of lower metal connecting piece using welding or are bolted；
The ball side pressure of upper metal connecting piece is entered in the upper spherical claw of upper and lower main reinforcement connection component；
Grout sleeve is put into the reserved grout sleeve mounting hole in upper precast construction column bottom surface；
The ball side pressure of lower metal connecting piece is entered in the lower spherical claw of upper and lower main reinforcement connection component；To make precast construction column
Main reinforcement and lower precast construction column main reinforcement are electrically connected；
Finally it is in the milk into grout sleeve.
Upper and lower precast construction column main reinforcement is welded or is bolted with metal connecting piece respectively by the present invention, and metal is connected
Part, which is pressed into spherical claw to be formed to embrace, grabs connection, and spherical claw and spring are welded, to realize that main reinforcement is electrically connected up and down.
Lightning protection downlead construction provided by the invention, has construction is simple, to structure safety without negative effect, does not influence pre-
The advantages that quality appearance of component processed.
The present invention has rational design, has good practical application and promotional value.
