detailed description

The present invention will be described in detail below using columns and beams of steel structures. It should be noted that the structure and principle of the present invention can also be applied to columns and beams of concrete structures or steel-concrete structures.

As shown in Figure 1-5, column 1 is a large box-shaped column welded by steel plates, and the width of the column is about 1.8-2.5 meters. Both ends of the column 1 are welded with built-in flanges 9, and the columns can be connected by bolts through the built-in flanges 9, or can be connected by welding.

The interior of the column 1 is provided with a column partition 4 , a column brace 7 and a vertical ladder 10 . The column partition 4 is made of narrow steel plate and fixed by welding around the inner wall of the box-shaped column. Column strut 7 is made of steel pipe or round steel, and the two ends of column strut 7 are respectively connected to the opposite inner walls of the box-shaped column by welding. This large box-shaped column structure with column partitions 4 and column struts 7 has good comprehensive mechanical performance, high load-bearing performance, and is not easily deformed, which solves the problems of unreasonable large box structure, easy deformation, and weak force at the joints. question.

The column strut 7 and the column partition 4 are provided with rotatable rollers, and the rollers can be ball bearings, rolling rings 11, or rollers with shafts. When the box-shaped column is transported horizontally, the girder 2 and other building components can be quickly and quickly installed and placed in the large box-shaped column through the rollers, which makes full use of the space of the box body, improves the transportation efficiency, and reduces the transportation cost . It should be noted that in practical applications, guide rails, or items with rollers, or other sliding or rolling devices can also be used to replace the rollers and column stays 7 in the above-mentioned box-shaped column, so as to facilitate the space in the column 1 transportation group. chamber load.

There are pin holes on the column, and movable beam pins 3 are installed in the holes, and column partitions 4 are welded on the inner side of the box-shaped column corresponding to the movable beam pins 3 to strengthen the strength of the connection and increase the load-bearing and resistance of the column. Shapeshifting ability. The movable beam pin 3 is in an active state on the cylinder, and can slide in the pin hole of the cylinder, and can stretch out from the outside of the cylinder and retract into the inside of the cylinder. The movable beam pin 3 can be pulled out from the column body when connection is required, and can be hidden in the column body when no connection is needed, without hindering transportation and lifting.

Both ends of the beam 2 are provided with connecting end plates, and the end plates are provided with threaded holes of standard modulus connected with the column 1, and the corresponding connecting holes are provided on the column. Bottoms at both ends of the beam 2 are provided with bottom plates, and positioning gaps 5 corresponding to the movable beam pins 3 are provided on the bottom plates, and elastic clips or snap rings are arranged below the positioning gaps 5 . When connecting, the movable beam pin 3 can be pulled out from the cylinder, and then the positioning gap 5 on the bottom of the two ends of the beam 2 is aligned with the movable beam pin 3, and the movable beam pin 3 is inserted into the positioning gap 5. Clip or jump ring clamp movable beam pin 3, then connect the connecting hole on the column with the threaded hole on the beam 2 two ends end plate with bolt. Welding holes 6 are also provided at the connection between the column and the beam, and the connection between the column 1 and the beam 2 can be further strengthened by welding if necessary. It should be noted that the positioning gap 5 on the beam 2 can also be replaced by a positioning hole or an elastic slot, the bolt connection between the column 1 and the beam 2 can be replaced by spot welding or full welding, and the elastic clip or circlip can be clamped by a retaining ring or other fixtures instead.

The vertical ladder 10 in the column is convenient for the construction personnel to operate and construct in the column 1. The bolt connection between the column 1 and the beam 2 can be carried out on the vertical ladder 10. When the upper column 1 is connected with the lower column 1, the vertical ladder 10 can The built-in flange 9 at the end of the upper column 1 and the lower column 1 is connected with bolts, and the welding operation can also be performed in the column 1, which is very convenient.
