A multi-component alloy co-infiltration treatment process for pre-embedded slabs of anti-fall beams

Abstract

The invention discloses a multi-component alloy co-permeation treatment process for anti-falling beam embedded plates. The process comprises the following steps that an embedded cylinder and an embedded rebar are welded together to form an embedded rebar cylinder, and a cylinder installation hole used for installing the embedded rebar cylinder is machined in each fixing plate; the cylinder installation hole of each fixing plate is filled with a multi-component alloy co-permeation isolation stopper which comprises a metal rod in the center and a glass fiber cloth wrapping the periphery of the metal rod; the outer side of the end, used for connecting the fixing plate, of the embedded rebar cylinder is wrapped by a glass fiber cloth; the surfaces of the fixing plates are treated to be clean, and then the treated fixing plates are stacked into stacks of which the height is close to the width and packed into bundles; the fixing plates and embedded rebar cylinders which are packed into bundles are put into a co-permeation furnace to be subjected to multi-component alloy co-permeation treatment; the embedded rebar cylinders and the fixing plates are assembled and welded together. According to the multi-component alloy co-permeation treatment process for the anti-falling beam embedded plates, co-permeation treatment can be conducted on the fixing plate separately, the space of the co-permeation furnace can be utilized efficiently, and therefore the operation efficiency of multi-component alloy co-permeation anti-corrosion treatment can be improved.

Description

technical field [0001] The invention relates to the technical field of an anti-corrosion treatment process for a pre-embedded plate of an anti-fall beam for a bridge, in particular to a multi-component alloy co-infiltration treatment process for a pre-embedded plate for an anti-fall beam. Background technique [0002] The embedded parts of bridges with reinforced concrete structure are prone to corrosion and damage the concrete structure of the bridge due to long-term exposure to various corrosion-causing factors such as freezing damage, chemical corrosion, steel corrosion, and alkali-aggregate reaction; especially due to humidity The effect of carbon dioxide, temperature and carbon dioxide will cause the carbonization of concrete, and the effect of corrosive media such as oxygen, sulfur dioxide and chlorine will further aggravate the corrosion of bridge embedded parts and the damage of concrete structure. Traditional anti-corrosion processes such as electro-galvanizing, ele...

Problems solved by technology

This is a pre-embedded slab for anti-fall beams commonly used in bridge infrastructure. The disadvantages of the pre-embedded slabs for anti-fall beams disclosed in the above-mentioned prior art are that it is difficult to perform multi-component alloy co-infiltration and anti-corrosion treatment. The material of the through-hole surface after anti-corrosion treatment is different from that of the fixed plate, and the welding performance of the through-hole surface after multi-component alloy co-infiltration anti-corrosion treatment will also change, thus affecting the welding firmness of the fixed plate and the embedded cylinder; However, the structure of the finished anti-fall beam pre-embedded slab including the fixed plate, pre-embedded cylinder and pre-embedded steel bars is more complicated, and it takes up a large space when heating and co-infiltration in the co-infiltration furnace, which leads to the loss of the anti-fall beam pre-embedded slab. The efficiency of multi-component alloy co-infiltration anticorrosion treatment is low
