Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0015] A method for positioning the H-shaped steel column of the cup mouth foundation, which is carried out according to the following steps (see figure 1 , figure 2 ):
A. Make a fixed block 2 ( image 3 , Figure 4 shown), the fixed block 2 is a welded member, which is an inverted T shape, which is formed by welding the bottom plate 2-1 and the vertical plate 2-2, and the rib plate is welded between the bottom plate 2-1 and the vertical plate 2-2. The size of 2-1 is 100×200×20mm, the size of the vertical plate 2-2 is 100×200×14 mm, the two sides of the bottom plate 2-1 are machined with four mounting holes with a diameter of 14 mm, and the vertical plate 2- There is a vertical groove 2-3 in the middle of 2, the width of groove 2-3 is 16 mm, and the depth h of groove 2-3 is the depth of H-shaped steel column 3 inserted into the cup mouth...

The invention discloses a cup foundation H-shaped steel column positioning method. Comprising the following steps that A, an inverted-T-shaped fixing block is manufactured, and a groove is formed in a vertical plate of the fixing block; b, a fixing block is installed on the bottom face of a cup opening of the cup opening foundation; c, a limiting block is manufactured, and a U-shaped groove with a downward opening is formed in the limiting block; d, the H-shaped steel column is inserted into a cup opening of the cup opening foundation, and a web of the H-shaped steel column is clamped into a groove of a vertical plate of the fixing block; e, a wedge is inserted into a gap between a flange plate of the H-shaped steel column and a cup opening of the cup opening foundation to fix the H-shaped steel column; f, adjusting the depth of the wedge inserted into the cup opening of the cup opening foundation to enable the center line of the H-shaped steel column to coincide with the axis of the upper surface of the cup opening foundation; and G, correcting and rechecking by using a measuring instrument to finish positioning. The fixing blocks are adopted to replace sizing blocks, the H-shaped steel column is positioned through the fixing blocks, construction is efficient, the problem that the H-shaped steel column cannot be fixed in the installation process due to the influence of a construction site is solved, and potential safety hazards of the construction site are reduced.
Description
technical field [0001] The invention relates to the construction of a cup mouth foundation, in particular to a positioning method for an H-shaped steel column of a cup mouth foundation. Background technique [0002] At present, in the field of building construction, the prefabricated steel structure is developing rapidly, and the prefabricated steel structure is suitable for factory production, integrating design, production, construction and installation. The prefabricated steel structure has fast construction progress, good seismic performance, low environmental pollution, recyclable, economical and environmentally friendly, and meets the requirements of green buildings. [0003] The steel column of the traditional prefabricated steel structure is installed on the foundation. The installation process of the traditional cup-mouth steel column is: there will be an installation axis determined by the civil engineering unit at the top of the foundation. When the steel structur...
