Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

Examples

Referring to fig. 1, 2, and 3, for a steel bridge column connection foundation structure provided by an embodiment of the present invention, as shown in fig. 1, 2, and 3, the structure includes a foundation main body, the foundation main body includes a foundation bottom plate 1 and a foundation top plate 2, and the foundation bottom plate 1 and the foundation top plate 2 are connected by a connecting plate 3 disposed longitudinally to form an integral structure; a plurality of supporting columns 4 protruding out of the lower surface of the foundation bottom plate 1 are fixedly connected to the foundation bottom plate 1, and a plurality of connecting holes 5 are formed in the foundation top plate 2;

the bottoms of the support columns 4 are used for realizing abutting joint with a ground foundation plate 7 so as to form a gap between the foundation bottom plate 1 and the ground foundation plate 7, and the gap is used for realizing press-in of backfill materials; the plurality of connecting holes 5 are used for realizing the detachable connection of the foundation top plate 2 and a column plate 8 of a steel bridge upright;

the base bottom plate 1, the base top plate 2 and the connecting plate 3 are all made of metal plates coated with anticorrosive coatings. The metal plate is a galvanized plate.

Further, be provided with regulating plate 6 between basic roof 2 with the column plate 8 of steel structure bridge stand, regulating plate 6 is used for realizing basic roof 2 with the relative distance between the column plate 8 of steel structure bridge stand. The foundation roof with the column plate of steel structure bridge stand is through passing the foundation roof, the regulating plate and the bolt assembly of the column plate of steel structure bridge stand realizes dismantling and is connected.

Further, the ground foundation plate is a concrete plate formed at the bottom of the groove on the ground. The inner contour of the groove in the ground is adapted to the outer contour of the base floor.

When the structure is used, the excavated ground forms a groove with a preset shape, the inner contour shape of the groove can be matched with the outer contour of the foundation slab, the broken stone is paved or concrete is poured on the broken stone to form a concrete slab at the vertical position of the column plate of the steel bridge column at the bottom of the groove, the lower end of the column on the foundation slab is in a preset construction position, the foundation slab and the ground foundation slab are separated from each other by the column to form a gap, and backfill can be pressed into the gap between the foundation slab and the ground foundation slab. The backfill can be gravel, sand, concrete and the like. The soil dug out during the groove digging can also be used for backfilling. Then the foundation top plate is connected with the column plate of the steel bridge upright post to form vertical support for the rigid frame bridge. In the foundation structure of this embodiment, the weight of the steel bridge column is supported by the independent foundation main body, and the load is transmitted to the lower ground foundation plate.

The surface of the foundation body is coated or galvanized, so that the foundation body has high antirust effect and cannot be corroded even if the foundation body is directly placed on the ground. Thus, it is not necessary to cover the periphery of the foundation body, which is usually required, with concrete. Therefore, the engineering quantity of templates, reinforcing steel bars and the like is reduced, and meanwhile, the excavated soil is backfilled, so that the excavated soil to be treated is reduced.

The material of the base body is not limited to the galvanized steel sheet, and may be made of various steel materials. The steel bridge upright is not limited to a square, but can be various steel columns. In addition, backfill can be pressed into the gap between the foundation slab and the ground foundation slab using various methods.

When the foundation body is installed, the excavated amount is small, the generation of vibration, noise and dust can be suppressed, and since concrete does not need to be placed, the construction period can be greatly shortened. In addition, the concrete and the steel are not required to be separated during dismantling, and the steel is easy to recycle. The height of the base and the height of the steel frame column can be adjusted by inserting the upper and lower adjusting nuts into the base bottom plate and screwing and loosening the adjusting bolts. In addition, the height can be adjusted by sandwiching the adjustment plate between the foundation bed and the steel bridge upright.

When the structure is installed, only excavation is needed around the foundation pit, the excavation amount is small, a large amount of residual soil can be processed on site, and the generation of vibration, noise and dust is inhibited. In addition, the construction period can be greatly shortened because concrete does not need to be poured. And the construction can also be carried out in narrow places. In addition, the concrete and the steel are not required to be separated during dismantling, and the steel is easy to recycle.
