Description
Technical Field
The utility model relates to a building engineering field specifically, relates to a steel construction column base anticorrosive device.
Background
The steel structure anticorrosion design is an indispensable content in the steel structure design. In addition to the anticorrosion treatment of conventional steel structures (steel columns, steel beams, supports and the like), additional anticorrosion treatment needs to be carried out on the steel column bases. According to engineering experience, when a concrete protective layer of a steel column embedded in soil does not extend out of the ground or the bottom surface of a column base has the same elevation as the bottom surface, impurities such as moisture, dust and the like are easily accumulated around the contact part of a column body (or the column base) and the ground (or the soil), so that the part is seriously corroded.
The conventional steel structure column base anticorrosion conventional method comprises the following steps: the part of the column base below the ground is wrapped by concrete with lower strength grade and thickness not less than 50mm, and the wrapped concrete is not less than 150mm higher than the ground. This conventional practice forms a "pier" at the toe, 150mm above the ground, projecting 50mm above the outer surface of the post. This practice can cause three problems: the use of the indoor effective area is influenced for a moment, because a plurality of indoor facilities or pipelines and the like cannot be arranged along the column; secondly, when in construction, steel bars need to be bound, templates need to be supported, concrete needs to be poured, and the construction is complex; and the indoor aesthetic effect can be influenced.
Patent document No. CN104912334A discloses a secondary grouting process for steel structure column base, comprising the following steps: the method comprises the following steps of foundation treatment, GSG high-strength non-shrinkage grouting material preparation and secondary pouring, wherein the part needing to be provided with a steel structure column base on a concrete foundation is subjected to enclosure arrangement of a wood plate formwork, then the steel structure column base is sleeved on a mounting bolt and is fixed by a nut, and finally the GSG high-strength non-shrinkage grouting material mixed with water is guided into the enclosure of the wood plate formwork to ensure dry and solid. According to the scheme, the wood plate enclosure and the grouting material are adopted for pouring, so that redundant column piers are formed outside the rigid column, the occupied space and the effective area are large, and the process is complex.
