Concrete bearing platform used for steel-structure stand column

Abstract

A concrete cap for a steel structure column, comprising a cap body, two rows of screw rods uniformly distributed along the length direction of the cap body, a horizontal steel sleeve plate, and two vertically arranged longitudinal pressure bearing plates, the The upper end of the screw protrudes from the top surface of the cap body, and its lower part is anchored in the cap body. The steel sleeve plate is provided with a plurality of positioning holes, and each positioning hole corresponds to the screw rod of the cap body. The screw rod passes through the corresponding positioning hole on the steel sleeve plate, and each screw rod is screwed with an adjusting nut on both sides of the steel sleeve plate. A longitudinal pressure-bearing plate is arranged on the inside of the two rows of screws, and the inside of the two rows of screws are connected to the outer sides of the two longitudinal pressure-bearing plates by spot welding, and a plurality of horizontal pressure-bearing plates are arranged at intervals between the two longitudinal pressure-bearing plates. connecting rod A. The concrete cap has simple structure and high load-bearing strength, and can ensure that the screw rod will not be displaced during the concrete pouring process.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a concrete cap used for steel structure columns. Background technique [0002] In the field of steel structures, it is often necessary to use concrete caps to fix steel structure columns during construction. This kind of concrete caps needs to fix multiple screws. The existing concrete caps are easy to shift the screws during pouring, which leads to It is difficult to align the mounting holes of the column chassis with the respective screw rods. Some existing concrete caps use reinforcement cages to cooperate with screws to prevent displacement. However, the assembly of such reinforcement cages requires a lot of man-hours, which increases the difficulty of construction for concrete caps. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a concrete cap for a steel structure column. The concrete cap has a si...
