Embodiment 1

[0039] A positioning and correcting device for steel structure columns on the first floor, such as figure 1 As shown in -5, the installation structure of the steel structure column positioning and correction device on the first floor consists of three basic components: the column bottom end plate 10, the conical head positioning screw 15 and the foundation positioning embedded part 1. The foundation positioning embedment is set at the part of the foundation to be installed, and the foundation positioning embedment is provided with a tapered groove and a positioning marking line with a guiding positioning function, and the upper surface of the foundation installation part is provided with a shear groove and a pre-embedded column foot fixing bolt; The end plate at the bottom of the column is set at the bottom of the steel structure column body on the first floor, and the end plate at the bottom of the column is provided with positioning screw holes, mounting and fixing holes and ...

Embodiment 2

[0049] The construction method of the positioning and correcting device for the steel structure column on the first floor includes the following steps:

[0050] Pre-embedding of foundation positioning embedded parts → fabrication and installation of column bottom and end plates → hoisting of steel structure column body → correction and connection of steel structure column → pouring, maintenance and removal of temporary support in the space under the column.

[0051] ①. Pre-embedded construction of foundation positioning embedded parts

[0052] The base positioning embedded part 1 is provided with a tapered groove 2 and a positioning marking line 3 with guiding and positioning functions, and the intersection point of the longitudinal and horizontal positioning marking lines 3 is located on the vertical center line of the tapered groove 2; Line and the plane central axis of the steel structure column body 4; according to the position and elevation of the foundation positioning e...

Abstract

The invention belongs to the field of construction, in particular to a device for positioning and correcting a first-layer steel structure column. The device is characterized in that a foundation positioning embedded part is arranged at a to-be-mounted part of a foundation, a conical groove with a guiding and positioning function and a positioning marking line are arranged on the foundation positioning embedded part, and a shear-resistant groove and an embedded column foot fixing bolt are arranged on the upper surface of a foundation mounting part; a column bottom end plate is arranged at thebottom of a first-layer steel structure column body, and a positioning screw hole, a mounting fixing hole and a slurry bleeding hole are formed in the column bottom end plate; and the drilling-in endof a conical head positioning screw is a cone, and the conical head positioning screw is installed in a column bottom end plate positioning screw hole. The device is simple in structure, low in construction technology difficulty, convenient to operate and safer and more reliable in joint connection quality. In the installation and construction process of a first-layer steel column component of a steel structure building, plane positioning and perpendicularity and elevation correction of the steel column component can be rapidly and accurately completed, the installation precision and construction efficiency of the first-layer steel column component of the steel structure building are improved, and economic benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of construction, and relates to a device for plane positioning, elevation and verticality adjustment and correction functions of a connection part between a steel structure column and an installation part under the column in the field of steel structure installation and construction, and an installation technology thereof. Background technique [0002] With the continuous acceleration of my country's economic development, the scale of urban construction and the level of industrialization have been improved by leaps and bounds. With the policy support and encouragement of governments at all levels, prefabricated building technology has been more and more applied. Compared with traditional cast-in-place concrete structure buildings, prefabricated buildings have the advantages of low construction difficulty, short construction period, less pollution to the surrounding environment, factory-based main components of the buil...
