Problems solved by technology

[0003] Steel components that have been galvanized have good surface hardness, but their surface corrosion resistance is poor; dacromet is also known as dacromet rust, high gram rust, zinc chromium film, etc. Aluminum sheet, chromic anhydride, ethylene glycol and other liquid treatment solutions are used to coat metal substrates, and after high-temperature baking, a layer of non-decorative coating film with excellent corrosion resistance is formed on the surface of the metal substrates. The disadvantage is that the surface hardness of the Dacromet coating is low, and it is easily damaged in friction and scratches

Abstract

The invention discloses a bridge cushion pad embedded installation seat machining method. The method comprises the following steps that a cushion pad limiting frame, embedded anti-floating rebars, an installation seat bottom plate and anti-deformation reinforced rib plates are machined; the above-mentioned components are welded together to form the bridge cushion pad embedded installation seat; surface oil cleaning and shot blasting treatment are conducted on the bridge cushion pad embedded installation seat; the whole bridge cushion pad embedded installation seat is immersed in a Dacromet coating solution; two corners, located at the two ends of a diagonal line respectively, of the installation bottom plate of the bridge cushion pad embedded installation seat are clamped and fixed, the level heights of the two fixed corners are the same, positions of the two fixed corners are fixed, and the bridge cushion pad embedded installation seat rotates around a connecting line between the two fixed corners to be leached; the bridge cushion pad embedded installation seat is sent to drying equipment to form a Dacromet coating; a cushion pad installation groove is fixed downwards and sprayed with a normal temperature curing blocking fluid, the attitude is kept, redundant closing fluid is leached, normal temperature curing is conducted, and a closing layer is formed.

Description

technical field [0001] The invention relates to the technical field of processing steel components for bridge construction and installation, in particular to a processing method for pre-embedded mounting seats of bridge buffer pads. Background technique [0002] The embedded mounting seat of the bridge buffer pad is a bridge construction and installation steel component used to increase the flexibility of the bridge structure, thereby prolonging the period of the structure to achieve the effect of shock absorption. Usually, rubber bearings are placed in the embedded mounting seat of the bridge buffer pad. Perform shock isolation. Due to the long-term exposure to freezing damage, chemical corrosion, steel corrosion, and alkali-aggregate reaction, the pre-embedded installation seat of the bridge buffer pad is more prone to corrosion and damage to the concrete structure of the bridge; especially due to humidity, temperature and The action of carbon dioxide will cause the carbo...
