Problems solved by technology

However, due to the small market share of split T-shaped steel, some large steel companies in my country also organize production according to orders. Therefore, the price of split T-shaped steel is higher than that of hot-rolled H-shaped steel, and the supply of goods is in short supply. Moreover, the section height of split T-shaped steel is limited (height is only half of the selected hot-rolled H-shaped steel), so there are almost no actual projects using steel special-shaped columns

Embodiment 1

[0046] Such as Figure 1 to Figure 3 , Figure 7 As shown, a kind of H-shaped steel combined special-shaped column portal frame structure assembly method of the present invention comprises the following steps:

[0047] Step 1, prefabrication preparation: Prepare the H-shaped steel required for connecting the longitudinal steel beams 11 of two adjacent special-shaped column portal frames in the factory according to the design drawings;

[0048] The special-shaped column portal frame is an end portal frame located at the end of the frame structure or a median portal frame located in the middle of the frame structure;

[0049] According to the design drawings, prepare the H-shaped steel required for the L-shaped column of the end portal frame at the end of the frame structure and the T-shaped column of the middle portal frame located in the middle of the frame structure in the factory;

[0050] Among them, the L-shaped column includes the main H-shaped steel 1 of the L-shaped c...

Embodiment 2

[0068] Such as Figure 4 to Figure 6 As shown, the difference between this embodiment and Embodiment 1 is that in step 1, the web plate of the main H-shaped steel 1 of the L-shaped column and a flange plate assembly position of the auxiliary H-shaped steel 2 of the L-shaped column are punched in advance in the factory. A row of installation holes; two rows of installation holes are drilled at the assembly position of the web plate of the main H-shaped steel 3 of the T-shaped column and a flange plate of the auxiliary H-shaped steel 4 of the T-shaped column;

[0069] In step 2, during the assembly process of the end-position portal frame, a flange plate of the auxiliary H-shaped steel 2 of the L-shaped column is connected to the end of the web plate of the main H-shaped steel 1 of the L-shaped column through two rows of third high-strength bolts 13 position, forming an L-shaped column;

[0070] During the assembly process of the central portal frame, a flange plate of the auxi...

Abstract

The invention discloses an assembling method for an H-shaped steel combined special-shaped column portal rigid frame structure. The assembling method comprises the steps that 1, prefabrication preparation is conducted; 2, the special-shaped column portal rigid frame is assembled; 3, an H-shaped steel combined special-shaped column portal rigid frame structure is assembled; And 4, a supporting system is assembled between the end-position portal rigid frame and the middle-position portal rigid frame adjacent to the end-position portal rigid frame. The special-shaped column is formed by directlycombining the hot-rolled H-shaped steel, and compared with a special-shaped column formed by welding the hot-rolled H-shaped steel and the split T-shaped steel, the special-shaped column has the advantages that sectional materials are convenient to purchase, the cost advantage is better, the section combination forms are richer, the section flexural rigidity is higher, and the engineering design requirement is easier to meet. The portal rigid frame structure can be used in an existing portal rigid frame structure with a bridge crane of less than 20 tons and an existing portal rigid frame structure with a bridge crane of more than 20 tons.

Description

technical field [0001] The invention belongs to the technical field of assembling a portal-type rigid frame structure with special-shaped columns, and in particular relates to a method for assembling a portal-type rigid frame structure with H-shaped steel combined special-shaped columns. Background technique [0002] The annual construction of single-storey industrial plants in my country is very large. The steel structure of portal frame light-weight houses is a commonly used structural system. The country has also promulgated and implemented the "Technical Specifications for Steel Structures of Portal Frame Light-weight Houses" and stipulates that the current domestic portal frame structures can only be used for lifting weights. Overhead cranes of A1~A5 working level with no more than 20 tons. According to the specification, the portal frame columns are H-shaped steel columns with constant or variable cross-sections, and the portal frame structure with bridge cranes adopt...
