Embodiment 1

[0045]Such as figure 1 , figure 2 As shown, the embodiment of the present application provides a butt connector 1, the butt connector 1 includes a positioning steel pipe 111, and at least two contact conductive pieces 112 and a plurality of elastic members 113 arranged inside the positioning steel pipe 111;

[0046] The two opposite contact conductive pieces 112 are respectively installed on the inner sidewall of the positioning steel pipe 111 through at least two elastic members 113 arranged along the length direction of the positioning steel pipe 111, and each contact conductive piece 112 is in the direction of the length of the butt joint 1. The edges are respectively bent in directions away from the central axis of the positioning steel pipe 111 .

[0047] Furthermore, using the positioning steel pipe 111 to insert other parts can not only realize the connection with other parts, but also realize the positioning function; the contact conductive pieces 112 are fixed by th...

Embodiment 2

[0055] Such as Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the embodiment of the present application provides a bridge pier, including the butt connector 1 in the first embodiment, and the down conductors 2 are respectively pre-embedded in the column 5, the cover beam 6 and the cap 7 of the bridge pier;

[0056] One end of the down-conductor 2 protrudes from the surface of the column 5 of the bridge pier, the cover beam 6 and the platform 7 respectively, and the other end of the down-conductor 2 that does not extend out of the surface of the column 5 and the cover beam 6 is connected with the butt joint 1 respectively. One end of the positioning steel pipe 111 is welded and connected, and the surface of the other end of the positioning steel pipe 111 is flush with the other surface of the column 5 and the cover beam 6;

[0057] Among them, the down conductor 2 adopts a specially designed flat steel, and the material and cross-sectional size should ...

Embodiment 3

[0070] Such as image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the embodiment of the present application provides a prefabricated component with lightning protection function, including the butt connector 1 in Embodiment 1, and at least one downconductor 2 that can be inserted into the butt connector 1, the butt connector 1 and the butt connector 1. The down conductors 2 are all arranged in the prefabricated components;

[0071] Wherein, one end of the down conductor 2 protrudes from the surface of the prefabricated component, and the other end is welded to one end of the positioning steel pipe 111 of the butt connector 1, and the surface of the other end of the positioning steel pipe 111 is flush with the other surface of the prefabricated component.

[0072] Specifically, welding connection is adopted between the down conductor 2 pre-embedded in the same component and the positioning steel pipe 111, and a plug connection is used between the down conduc...

Abstract

The invention provides a butt joint connection piece, a prefabricated component and a bridge pier and relates to the technical field of building lightning prevention. The butt joint connection piece comprises a positioning steel pipe, at least two contact conductive pieces arranged in the positioning steel pipe and a plurality of elastic pieces; the two oppositely arranged contact conductive pieces are installed on the inner side wall of the positioning steel pipe through the at least two elastic pieces arranged in the length direction of the positioning steel pipe; and each contact conductivepiece is bent in the direction away from a center shaft of the positioning steel pipe at the edge of the butt joint connection piece in the length direction, and therefore down leads are inserted inconveniently. The butt joint connection piece is applied to the prefabricated component or the bridge pier with the lightning prevention function, along with insert-in of the down leads, the elastic pieces in the positioning steel pipe are extruded and deformed, so that the contact conductive pieces and the down leads are in close contact, and therefore effective connection between the down leadsis achieved, it is guaranteed that a good electric access is formed between lightning preventing devices, and an integrated lightning preventing protecting system is formed.

Description

technical field [0001] The invention relates to the technical field of building lightning protection, in particular to a butt connector, a prefabricated component and a bridge pier. Background technique [0002] Most of the original bridge piers were built by integral casting, and the lightning protection structure was buried in the bridge piers during the construction process, but the bulk of the bridge piers is too large, and it is inconvenient to adopt the integral casting method; the existing bridge piers are usually assembled by prefabricated components The method of construction, and this assembly method is easy to operate, and it also needs to meet the requirements of pre-embedded lightning protection structures inside this assembled pier. [0003] In the prior art, the down conductors pre-embedded in each prefabricated component may not be able to be effectively connected as a whole, so that they cannot be penetrated, so that the pier cannot form a good electrical pa...
