Embodiment 1

[0026] Embodiment 1: As shown in the figure, a high-strength box-shaped composite column includes two C-shaped steel plates 1 and four column plates 21, 22 made of bamboo / wood, and the openings of the two C-shaped steel plates 1 are opposite to each other. Set and surround a box-shaped framework, four column plates 21, 22 are pasted and fixed on the four outer surfaces of the box-shaped framework respectively, and a plurality of transverse partitions 3 distributed along the length direction are arranged in the box-shaped framework. A first connection hole 23 is provided on the opposite column plate 21, a second connection hole 11 is provided on the flange of the C-shaped steel plate 1, a third connection hole 31 is provided on the diaphragm 3, and the connection screw 4 passes through The rear two ends of the first connection hole 23, the second connection hole 11 and the third connection hole 31 are fixed by pads 5 and nuts 6, so that the diaphragm 3 is fixed to the box-shaped...

Embodiment 2

[0030] Embodiment 2: As shown in the figure, a method for preparing a high-strength box-type composite column includes the following specific steps:

[0031] (1) Take two C-shaped steel plates 1, and drill multiple groups of second connection holes 11 distributed at intervals along the length direction on the flange of the C-shaped steel plates 1. A plurality of groups of first connecting holes 23 equidistant from the second connecting holes 11 are drilled on the column plate 21 of bamboo / wood;

[0032] (2) The column plates 22 made of bamboo / wood are bonded and fixed on the outer surfaces of the webs of the two C-shaped steel plates 1 with an adhesive;

[0033] (3) A third connecting hole 31 is provided on the opposite sides of the transverse partition 3;

[0034] (4) In the same C-shaped steel plate 1 , the position corresponding to the second connection hole 11 is pasted and fixed with an adhesive in order to fix the diaphragm 3 , and the third connection hole 31 on the tr...

Abstract

The invention discloses a high-strength box-type combination column and a preparation method thereof. The high-strength box type combination column is characterized in that the high-strength box-type combination column comprises two C-type steel plates and four column plates made of bamboo / wood, the two C-type steel plates define a box-type framework, the four column plates are respectively pasted and fixed on four outer surfaces of the box-type framework, a plurality of transverse partition plates distributed at intervals in the length direction are arranged in the box-type framework, a connecting screw rod penetrates through a first connecting hole, a second connecting hole and a third connecting hole, then the two ends of the connecting screw rod are fixed through cushion blocks and nuts, and polygonal holes are formed in the cushion blocks. The high-strength box-type combination column has the advantages that the overall weight and cost are reduced, and meanwhile the bending resistance and the shearing resistance of the box-type column are guaranteed; and in addition, due to the fact that the transverse partition plates are fixedly connected with the box-type framework through the connecting screw rod, later replacement and maintenance of the box-type combination column are facilitated, when the box-type combination column is damaged due to stress, the box-type combination column can be conveniently disassembled only by heating to melt epoxy resin glue, and repeated use can be achieved by replacing the damaged part of the box-type combination column.

Description

technical field [0001] The invention relates to a box-shaped column in the field of construction engineering, in particular to a high-strength box-shaped composite column and a preparation method thereof. Background technique [0002] Conventional support columns or load-bearing columns in house construction are made of reinforced concrete. The construction of this form of support columns is cumbersome, the construction period is long, and batch processing cannot be performed in advance. In order to solve the above problems, some box columns are directly spliced ​​by four steel plates, and multiple partitions are fixed inside the box column to increase the bending and shear resistance of the box column. However, the steel plates of this box-shaped column and between the partition plate and the steel plate are all 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.
