Anti-beam-lowering bridge embedded board facilitating surface preservative treatment

Abstract

The invention discloses an anti-beam-lowering bridge embedded board facilitating surface preservative treatment. The anti-beam-lowering bridge embedded board comprises a fixing plate, embedded cylinders and embedded bars. A plurality of installation through holes used for installing the embedded cylinders are formed in the fixing plate. Each embedded cylinder comprises an installation end and an embedded end, wherein an installation screw hole is formed in the installation end of the embedded cylinder, and the installation end of the embedded cylinder is located in the corresponding installation through hole. Each embedded bar comprises a welding end and a bending end, wherein the welding end of the embedded bar is welded to the embedded end of the corresponding embedded cylinder. An internal installation thread is arranged on the inner wall of each installation through hole. An internal installation thread matched with the internal installation thread of the corresponding installation through hole is arranged on the outer side wall of the installation end of each embedded cylinder. According to the anti-beam-lowering bridge embedded board facilitating surface preservative treatment, multicomponent alloy co-diffusion treatment can be conducted on the fixing plate independently, the space of a co-diffusion furnace can be utilized efficiently, and thus the operation efficiency of the multicomponent alloy co-diffusion treatment of the anti-beam-lowering bridge embedded board is improved.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion treatment technology for a pre-embedded anti-fall beam plate for bridges, in particular to a pre-embedded anti-fall beam plate for bridges which is convenient for surface anti-corrosion treatment. 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, electro-ca...

AI Technical Summary

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
