Abstract

The invention discloses a high-strength box-shaped composite column and a preparation method thereof, which is characterized in that it comprises two C-shaped steel plates and four column plates made of bamboo / wood, and the two C-shaped steel plates form a box-shaped skeleton. The four column plates are respectively pasted and fixed on the four outer surfaces of the box-shaped frame. There are a plurality of transverse partitions distributed along the length direction in the box-shaped frame. The connecting screw passes through the first connecting hole, the second connecting hole and the The two ends of the third connection hole are fixed by pads and nuts, and the pads are provided with polygonal holes; the advantage is that the box-shaped composite column reduces the overall weight and cost, and also ensures the bending and shear resistance of the box-shaped column capacity; and because the transverse diaphragm is fixedly connected to the box-shaped frame through the connecting screw, it facilitates the replacement and maintenance of the box-shaped composite column in the later stage. When the box-shaped composite column is damaged due to force, it only needs to be heated to melt the epoxy resin glue. The box-type combined column can be easily disassembled, and the damaged part can be replaced to be reused.

Description

Technical field [0001] The present invention relates to a box column in the field of construction engineering, in particular to a high-strength box-type combination column and a method of preparation thereof. Background [0002] The conventional support columns or load-bearing columns in housing construction are made of reinforced concrete pouring, and this form of support columns is troublesome, has a long construction period, and cannot be processed in batches in advance. In order to solve the above problems, some box columns are directly spliced through four steel plates, and multiple partitions are fixed in the box column to increase the bending and shear resistance of the box column. However, the steel plates of this box column, as well as between the separators and the steel plates, are fixed by welding, which makes its assembly troublesome, and cannot be disassembled and replaced, and the overall weight is large and the cost is high.
