Problems solved by technology
In the construction process, it is more common to use traditional column tops to pre-embed steel structure embedded parts. However, due to the difference between the concrete construction accuracy and the steel structure accuracy specification requirements, the pre-embedding accuracy often cannot meet the construction requirements, which increases the column top. The installation difficulty of the steel structure reduces the construction efficiency. At the same time, due to the construction of the embedded parts and the machining accuracy of the contact surface of the steel structure at the top of the column, the embedded parts at the top of the column and the steel structure cannot be tightly fitted, and there is a problem of unbalanced structural force.

Embodiment Construction
[0018] The present invention is further illustrated below by specific examples.
[0019] Such as Figure 1~Figure 3 As shown, a column top steel structure quickly installs a limit connection node structure, including a steel column or a concrete column 3 with embedded steel plates, and a column top steel structure 4; it also includes a limit conversion piece 1 and a force transmission pad 2; , the limit conversion part 1 is a flat plate, on which a stud is vertically arranged and a rectangular through-slot is arranged in the middle of the flat plate, and the force transmission backing plate 2 includes a flat plate and a center of the bottom of the flat plate. Rectangular protrusions and through holes are set around the plate, the position of the rectangular protrusions matches the position of the rectangular groove of the limit transition piece 1, and the position of the through holes matches the position of the stud on the limit transition piece 1 match; the top of the force...

The invention relates to the field of steel structure construction, in particular to a quick mounting, limiting and connecting joint structure for a column top steel structure. The quick mounting, limiting and connecting joint structure comprises a concrete column (3) and the column top steel structure (4), and is characterized by further comprising a limiting conversion part (1) and a force transmitting base plate (2), wherein the limiting conversion part (1) is arranged on the top of the concrete column (3); the force transmitting base plate (2) is arranged on the limiting conversion part (1), and a nut sleeves a stud for fastening the force transmitting base plate (2) to the limiting conversion part (1); and the column steel structure (4) is arranged on a cross supporting steel plate ofthe force transmitting base plate (2). A force transmitting way of the connecting joint is clear, mounting can be achieved once, construction is convenient and quick, and deviation can be adjusted during mounting.
Description
technical field [0001] The invention relates to the field of steel structure construction, in particular to a column top steel structure fast installation limit connection node structure. Background technique [0002] In recent years, with the rapid development of the steel structure building structure system in my country, on the premise of satisfying the basic functions of the building, the building roof structure system has more choices, and the application of the space roof steel structure and its supporting system is becoming more and more extensive. . In the construction process, it is more common to use traditional column tops to pre-embed steel structure embedded parts. However, due to the difference between the concrete construction accuracy and the steel structure accuracy specification requirements, the pre-embedding accuracy often cannot meet the construction requirements, which increases the column top. The installation difficulty of the steel structure reduces ...
