example 1

[0016] Such as figure 1 , figure 2 As shown, in construction engineering, the column 1 and the beam 3 usually used are welded by three steel plates, and their cross-sectional shape is generally H-shaped. Existing technologies such as figure 1 As shown, at the connection between the column and the beam, it is necessary to cut and process a thickened column flange plate 2, and a hole corresponding to the size and shape of the flange plate should also be cut on the column 1, and then the thickened flange plate The plate is welded on the column 1 here, and the weld needs to be ultrasonically inspected. Use high-strength bolts to connect the flange plate 2 welded on the column 1 and the end plate 4 welded on the beam 3, so that the column and the beam are connected together. The characteristics of the present invention are as figure 2 As shown, the thickened flange plate 20(t 2 ) and the flange plate (joint part) of steel column 1 should be straight on the surface, and then ...

example 2

[0018] Such as image 3 , Figure 4 As shown, the two beams 6 are also H-shaped components welded by three steel plates. In the figure, a shows the schematic diagram of the axial connection relationship between the two beams; in the figure, b shows the cross-sectional H-shaped schematic diagram of the beams. Existing technologies such as image 3 As shown, the two steel beams 6 are connected together by the flange plate splicing plate 7, the web splicing plate 8, and the high-strength bolts 9; the two steel beams 6 can also be connected together by riveting. The present invention is for the connection of this two beams, as Figure 4 As shown, its structural feature is that the two steel beams 6 are directly glued and connected together by using the flange plate splicing plate 7 and the web splicing plate 8 through the adhesive layer 10 . (the specific implementation method is the same as embodiment 1)

example 3

[0020] For the parts with insufficient strength of the combined steel plate type steel structure, it is necessary to set up reinforcement members. Existing technologies such as Figure 5 Shown, be welded on the insufficient strength position of original steel component 11 with reinforced steel plate 12, its weld seam is represented by 13; The present invention is as Image 6 As shown, the reinforced steel plate 12 is strengthened and connected to the original steel member 11 with an adhesive layer 14, which is convenient and practical (the specific implementation method is the same as that of embodiment 1).

Abstract

The invention relates to the architect steel structure glue connecting art. The invention mainly solves the connecting and enforcing of the built-up steel board component that the intersection is H shaped, to improve the produce effect and to decrease the cost. It is characterized in that another steel board is glue connected on the steel component at the location of the built-up steel board connecting location or the enforcing location. For example, the steel board of a thickening flange plate is need to be glue connected on the steel post, the flange splice plate and the web splice plate will glue connect the two H shaped steel bars, the enforcing steel board is glue connected at the enforcing location of the steel component. The invention could be widely used in connecting of the girder, the post and other built-up steel structure components in the architect field.

Description

technical field [0001] The invention belongs to a method for strengthening connection of steel components, and relates to the technology of mutual connection of steel plate composite components. Background technique [0002] In the field of construction, a large number of steel components welded by the combination of steel plates are used, for example, beams and columns with H-shaped cross-sections are welded by three steel plates. The connection between the beam and column members often uses high-strength bolts to connect the end plate welded to the beam end and the column flange plate to form a structure. The thickness of the beam end plate and the column flange plate at the connection part should generally be equal to or greater than the diameter of the high-strength bolt to ensure their bending and shear strength and stiffness requirements. Therefore, the column flange steel plate welded by the combination of three steel plates needs to be thickened at the connection pa...
