Problems solved by technology

[0002] The prefabricated foundations used in the field of transmission lines mainly include two forms: steel assembly foundation and concrete slat + steel assembly foundation. The steel assembly foundation is composed of the bottom plate, the upper support and the bottom connection structure, but both types have the following disadvantages: the upper structure is easily displaced by the steel structure through bolted connections, and the quality and service life of the underground steel structure anti-corrosion measures are difficult. ensure

Embodiment Construction

[0015] refer to figure 1 —3. The present invention includes a column 1, a base plate 2, and a beam 3. The base plate 2 has two pieces, each of which is composed of several concrete panels. An anchor bolt 5 is pre-embedded, and the anchor bolt 5 passes through the reserved bolt hole of the bottom plate 2 and connects the beam 3 and the bottom plate 2 as a whole through the channel steel 6. The flange plate 4, the assembled bottom plate 2 and the column 1 are connected through the flange plate 4 to form a complete assembled foundation. The channel steel 6 connecting the beam 3 and the bottom plate 2 and the flange plate 4 are weather-resistant steel, which can reduce the Corrosive effect of groundwater on steel structures.

[0016] The fabricated foundation channel steel and flange plate provided by the invention adopt weathering steel, which can reduce the corrosion effect of groundwater. The inclined column foundation can reduce the effect of horizontal force on the foundatio...

Abstract

The invention provides a batter post expansion plate type assembling foundation adopting weathering resistant steel for connection, and relates to the technical field of high-voltage transmission lines. The batter post expansion plate type assembling foundation comprises a stand column, bottom plates and a beam. The number of the bottom plates is two, the beam is arranged under the two bottom plates, anchor bolts are buried in the beam in advance, the anchor bolts penetrate through preset bolt holes in the bottom plates and then connect the beam and the bottom plates to be a whole through steel channels, a flange disc is buried in the lowest end of the stand column in advance, and the bottom plates and the stand column are connected through the flange disc to form a complete assembling foundation. The steel structure is long in service life, the batter post foundation is small in size, the construction period can be shortened by 1/3 to 1/2, labor on site can be saved by about 30% to 50%, limit of construction seasonality is overcome, material conveying amount is reduced, and efficiency of construction particularly in mountainous areas and hill sections is greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of high-voltage transmission lines, in particular to a slanted column expansion plate assembly foundation connected by weathering steel. Background technique: [0002] The prefabricated foundation used in the field of transmission lines mainly includes two types of steel assembly foundation and concrete slat + steel assembly foundation. The steel assembly foundation is composed of the bottom plate, the upper bracket and the bottom connection structure, but both types have the following disadvantages: the upper structure is easily displaced by the steel structure through bolted connections, and the quality and service life of the underground steel structure anti-corrosion measures are difficult. ensure. Invention content: [0003] The object of the present invention is to provide a prefabricated foundation spliced ​​by concrete components with short construction period and high construction efficiency. ...
