Steel column strip substrate structure system and one-off mounting and fixing method thereof

Abstract

The invention discloses a steel column strip substrate structure system. The steel column strip substrate structure system comprises a substrate and a vertical steel column located on the substrate, wherein a short joint bar is arranged on the substrate; a plurality of stiffening rib fixing boards which are jointed and fixed by the short joint bar are jointed with the outer wall of the steel column; an ejector board in contact with an externally-arranged jack is arranged on each stiffening rib fixing board. Furthermore, the invention further discloses a one-off mounting and fixing method of the steel column strip substrate structure system. The ejector boards of the stiffening rib fixing boards provided by the invention provide a support and stress part for the jack, so that the jack adjusts the perpendicularity and the horizontal angle of the steel column, and then can be used for directly welding the steel column with the short joint bar. Therefore the steel column strip substrate structure system is mounted and fixed in one step, so that the steel column is synchronously constructed by positioning, correcting and fixed embedding. The effect correction of the substrate and the substrate at the upper part is enhanced through the short joint bar; meanwhile, loads in an early-period mounting and fixing and later-period structure construction are transferred to the substrate, so that the security of the entire structure construction system is ensured. The steel column strip substrate structure system and the one-off mounting and fixing method thereof provided by the invention can be widely used in the construction field.

Description

technical field [0001] The invention relates to a steel column positioning, rectification and fixing pre-embedded structural system in the field of building construction, and its corresponding installation and fixing method. Background technique [0002] At present, the steel structure column foundation in the field of building construction generally adopts a cup-shaped foundation to install the base, or a method of secondary construction of the base pre-embedded superstructure. The method of installing the base on a cup-shaped foundation has the problem of difficulty in controlling the verticality and horizontal elevation in actual construction; at the same time, when fixing the base, inserting a wedge is easy to cause damage to the cup mouth, thus affecting the installation stability and construction safety. However, the secondary construction method of pre-embedding the superstructure of the foundation will inevitably have an adverse effect on the structural system due t...

The method of installing the base on a cup-shaped foundation has the problem of difficulty in controlling the verticality and horizontal elevation in actual construction; at the same time, when fixing the base, inserting a wedge is easy to cause damage to the cup mouth, thus affecting the installation stability and construction safety

However, the secondary construction method of pre-embedding the superstructure of the foundation will inevitably have an adverse effect on the structural system due to the increase of construction joints in the structure; at the same time, due to the secondary construction, there are also problems in the construction progress and construction integration process. certain limitations
