Problems solved by technology

However, due to the thinner secondary pouring layer, as the current of the electrolytic cell increases, the load transmitted to the busbar pier becomes larger and larger, resulting in the phenomenon of fracturing at the top of the busbar pier

Embodiment Construction

[0009] Attached below figure 2 The present invention will be described in further detail with specific embodiments.

[0010] The structure of the present invention is: it comprises reinforced concrete buttress 1, steel bar 2, stirrup bar 3, and steel bar 2 is higher than one pouring elevation 40mm, and the top of steel bar 2 is provided with encrypted stirrup bar 5 and steel bar 2 welding, secondary fine stone concrete The leveling layer 4 has a thickness of 100mm.

[0011] Construction method of the present invention is as follows:

[0012] In the first step, the reinforced concrete pier 1 is constructed to 100mm below the required level, but the short column steel bar 2 needs to be extended to 40mm above the primary pouring level, and three encrypted stirrup bars 5 need to be placed on the top of the steel bar 2, and they must be connected with the steel bar 2 Solder firmly.

[0013] In the second step, after the concrete pier 1 reaches the design strength, the construct...

Abstract

The invention discloses an insulating and anti-cracking structure and a construction method of a bus buttress of an aluminum electrolytic workshop. The insulating and anti-cracking structure comprises a reinforced concrete buttress (1), rebars (2) and a stirrup (3), the rebars (2) are 40 mm (millimeter) higher than the elevation of a primary casting, encryption stirrups (5) are arranged at the top of the rebars (2) and are welded with the rebars (2), and the thickness of a secondary fine aggregate concrete leveling course (4) is 100 mm. The construction method includes that the elevation of the primary casting is -100 mm of the elevation of a pier top; the rebars (2) need to extend to more than 40mm of the elevation of the primary casting, the stirrup (3) of a construction pier is welded with the rebars (2), three encryption stirrups (5) are arranged at the top of the rebars (2) at an interval of 50mm and are firmly welded with the rebars (2); after strength of the reinforced concrete buttress (1) reaches the design strength, the construction of the secondary fine aggregate concrete leveling course (4) with a thickness of 100mm is carried out.

Description

technical field [0001] The invention relates to an insulating and anti-cracking structure and a construction method of a bus bar support pier in an aluminum electrolysis workshop. Background technique [0002] In the production process of the aluminum electrolysis workshop, high-intensity current needs to be provided to the electrolytic cell, so a busbar for transmitting current is configured, and the structure needs to be matched with the design of the concrete buttress supporting the busbar. The usual practice is to pour the reinforced concrete pier to 50mm below the required elevation, and pour a 50mm thick fine stone concrete leveling layer on it for the second time, which also serves as an insulating layer. However, due to the thinner secondary pouring layer, as the current of the electrolytic cell increases, the load transmitted to the busbar pier is also increasing, resulting in the top part of the busbar pier being fractured. Contents of the invention [0003] The...
