Background
The traditional steel column is a closed combined member and is connected with a foundation in an embedded or externally-wrapped manner, and the embedded depth is 2-3 times of the outer diameter of the member generally; for example, a circular tube concrete column with the diameter of 800mm needs 2.4 meters for embedding depth; in the traditional closed combined member, the column is not forked, the concrete column is inserted into the concrete, the prying bar effect is realized, and the bending resistance and the pulling resistance can be realized only by increasing the anchoring depth; therefore, the excavation depth of the foundation pit is large, the used equipment cost and labor cost are greatly increased, and the construction period is also increased.
Disclosure of Invention
The invention aims to provide a combined column which effectively reduces the excavation depth of a foundation pit and the comprehensive manufacturing cost on the premise of not increasing the steel cost and ensuring the embedding effect.
In order to achieve the purpose, the invention provides a column base forked type combined column capable of reducing anchoring depth, wherein a column base of the combined column is cut upwards from the bottom of the column base to form a plurality of anchoring plates; the bottom of each anchoring plate is forked towards the outside of the column to form a dispersed tree root structure; gaps generated by bifurcation of the anchoring plates are used for connecting the concrete in the combined column tube and the concrete outside the combined column tube into a whole.
Furthermore, the combined column is a cylinder, and the column base of the cylindrical combined column is cut at equal intervals to be divided into a plurality of the anchoring plates with equal areas.
Furthermore, the combined column is a rectangular column, and at least one anchoring plate is cut on each surface of a column base of the rectangular column.
Further, when the combined column is fixed with a foundation, the plane of the foundation is 10cm higher than the upper edge of the anchoring plate;
the anchoring depth of the combined column in the foundation is 25-50 times of the wall thickness of the combined column.
Furthermore, the surface of the anchoring plate is additionally provided with welding studs, so that the embedding effect with the foundation is further enhanced.
Furthermore, the bottom of the combined column is connected with an anchoring end plate.
Compared with the prior art, the invention has the advantages that:
1. the invention directly cuts the column foot to form the anchoring plate which is forked towards the outside of the column to be used as a reinforcing piece, so that the whole steel area of the combined column is not changed, but the embedding effect between the combined column and the foundation is effectively enhanced.
2. According to the invention, the holes are formed at the column foot positions of the combined column, so that the concrete in the tube and the concrete outside the tube are connected into a whole, and the anchoring end plate is additionally arranged at the bottom, so that the anchoring depth of the steel column can be greatly reduced on the premise of ensuring the embedding effect; the anchoring depth is related to the wall thickness of the steel column, and is 25-50 times of the wall thickness, so that the requirement of pulling resistance can be met; if the wall thickness is 10mm, the embedding depth is 250-500 mm, and the embedding effect can be achieved; the excavation depth of the foundation pit is greatly reduced, and the comprehensive cost is reduced.
3. The column base of the combined column is directly stressed, secondary stress conversion is avoided, force transmission is reliable, and efficiency is high; if necessary, welding studs can be added on the embedded part of the anchoring plate to further enhance the embedding effect.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described below.
The invention provides a column base turnout type combined column capable of reducing anchoring depth, which is a column base turnout type combined column 1; cutting a column base of the combined column 1 upwards from the bottom of the column base to form a plurality of anchoring plates 2; the bottom of each anchoring plate 2 is forked towards the outside of the column to form a dispersed tree root structure; gaps formed by bifurcation of the anchoring plates 2 are used for connecting the concrete in the pipe and the concrete outside the pipe of the combined column 1 into a whole; the forked reinforcing plate does not increase the steel consumption of the original combined column 1, the whole steel consumption cost is not increased, but the forked reinforcing plate is similar to the structure of a tree root, so that the tensile strength and the rejection strength between a column base and a foundation 3 are increased. Meanwhile, the anchoring plate 2 is forked to form a gap, so that the concrete in the pipe and the concrete outside the pipe are connected into a whole, and the anchoring end plate 4 is additionally arranged at the bottom of the pipe, so that the anchoring depth of the steel column can be greatly reduced on the premise of ensuring the embedding effect; the anchoring depth is related to the wall thickness of the steel column, and is 25-50 times of the wall thickness, so that the requirement of pulling resistance can be met; if the wall thickness is 5mm, the embedding depth is 250-500 mm, and the embedding effect can be achieved; the excavation depth of the foundation pit is greatly reduced, and the comprehensive cost is reduced. Meanwhile, the anchoring plate 2 is formed by processing a cutting material provided with a hole, so that the steel area of the whole combined column 1 is unchanged, and the steel cost is not increased.
When the combination column 1 is fixed with the foundation 3, the plane of the foundation 3 is 10cm higher than the upper edge of the anchoring plate 2, so that the strength of the joint of the plane of the foundation 3 and the combination column 1 is ensured.
As shown in fig. 1 and 2, the composite column 1 is a cylinder, and the column base of the cylindrical composite column 1 is cut at equal intervals to be divided into a plurality of equal-area anchor plates 2.
As shown in fig. 3 and 4, the composite column 1 is a rectangular column, and at least one anchoring plate 2 is cut out of each surface of a column base of the rectangular column;
in this embodiment, if necessary, a stud 5 may be added to the anchor plate 2 of the embedded portion to further enhance the embedding effect.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
