Problems solved by technology

[0002] In industrial buildings, large metal silos installed on concrete frames have large embedded steel plates (embedded parts) on the top surface of the support beams. The upper surface of the embedded parts requires high precision for installation flatness, but due to There are many anchor bars and long bars, and the beam bars of the lower structure are dense. When the embedded parts are installed, many anchor bars welded and shaped collide with the beam bars. It is very difficult to install, and it is difficult to ensure the elevation and surface smoothness.

Embodiment Construction

[0016] As shown in the figure, a method of installing large embedded parts includes the following steps:

[0017] (1) Preparatory work: including making steel plate temporary support steel bar 4, embedded steel plate 1 and anchor bar 3, when making steel plate temporary support steel bar 4, weld the steel bar into a U-shaped frame, and weld the steel bar at the corner of each U-shaped frame The outriggers, and each side of the U-shaped frame is set 50mm wider than the steel plate. When making the steel plate 1 of the embedded part, cut the steel plate according to the designed size. The steel plate is cut in sections, each length is 1.5~2m, and the position of the anchor bar 3 is calibrated according to the arrangement of the anchor bar 3 of the embedded part, and the V-shaped hole 2 is cut at the position of the anchor bar 3. The geometric size of the hole is based on the thickness of the steel plate, After the diameter of the anchor bar is cut according to the requirements i...

Abstract

The invention belongs to the technical field of large embedded steel plate installation of metal storage bin supports, and particularly discloses an installation method of a large embedded part. The installation method specifically includes the steps that anchor bars are not welded to the embedded part first, but according to requirements of elevation and flatness, a steel plate of the embedded part is leveled, aligned and fixed by welding with temporary frame vertical bars supporting, and then the anchor bars are sequentially inserted and welded firmly according to a perforated plug welding mode, so that the steel plate is installed, aligned and leveled without the anchor bars, and the accuracy is easy to ensure; and the anchor bars are inserted separately one by one, and the anchor barsare very easy to insert into a steel bar framework of a lower support beam.

Description

technical field [0001] The invention belongs to the technical field of installing large-scale pre-embedded steel plates for metal silo supports, and in particular relates to a method for installing large-scale pre-embedded parts. Background technique [0002] In industrial buildings, large metal silos installed on concrete frames have large embedded steel plates (embedded parts) on the top surface of the support beams. The upper surface of the embedded parts requires high precision for installation flatness. There are many anchor bars and long bars, and the beam bars of the lower structure are dense. When the embedded parts are installed, many anchor bars welded and shaped collide with the beam bars. It is very difficult to install, and it is difficult to ensure the elevation and surface smoothness. Contents of the invention [0003] The purpose of the present invention is to provide a method for installing large pre-embedded parts, which adopts the installation method of ...
