Description
Technical field
The present invention relates to vertical section column technical field is supported, more particularly to a kind of Flos Mume suitable for grid frame supported framework
Post and its installation method.
Background technology
Tree-shaped post or Flos Mume rod structure are one kind of space biomimetic features, are a kind of relatively new version, have
Rational Path of Force Transfer, bearing capacity are higher, and Support cover scope is wide, can form larger supporting and space with less rod member.
More application is had abroad, and also increasingly extensively, particularly in some large-span space structures, which is applied for utilization at home
Architectural image it is unique, space structure flexible arrangement is changeable, and structural steel amount is few, has more complied with the big of current energy saving building
Trend.In prior art, a plurality of son field steel pipe is typically all directly welded on a steel pipe of vertical section, the space bit of installation
Put that axis is independent, absolute altitude differs, angle is different, stress is more complicated, connection reliability between son field steel pipe and straight section connector
It is low；Vertical section steel pipe is single one, in irregular shape, is obstructed during the institute's stress going down of son field steel pipe top, it is impossible to
Reasonably distribute to the shaft of vertical section column, cause vertical section column that destruction easily occurs.Moreover, in prior art,
The end points space coordinatess of each branch's steel column are different from, it is difficult to control, and affect construction quality.
The content of the invention
It is an object of the invention to provide a kind of plum blossom pillar and its installation method, solve a plurality of son field steel in prior art
Pipe is directly welded on piece steel pipe of vertical section, the locus axis of installation is independent, absolute altitude differs, angle is different, stress is multiple
Miscellaneous, the low technical barrier of connection reliability between son field steel pipe and straight section connector；Also due to vertical in solution prior art
Duan Gangguan is single one, son field steel pipe top institute's stress going down when be obstructed, reasonably can not distribute to vertical section
On the shaft of column, cause vertical section column that the technical problem destroyed easily occurs.
To realize above-mentioned technical purpose, the present invention is adopted the following technical scheme that：
A kind of plum blossom pillar, including the bottom suspension column part being fixedly connected with built-in fitting, the vertical section that is connected on suspension column part with
And the son field of top, the son field is made up of some son field steel pipes, it is characterised in that：
The vertical section is closed up by the same number of vertical section column of number and son field steel pipe and is formed；
The top of the vertical section is fixedly connected by branched connection members with the bottom of son field；
The branched connection members are integrally formed steel-castings, including the uniform arrangement that makes a circle in week branch's connection sleeve pipe and
Branch's yoke plate that branch's connection sleeve pipe is connected by centre；The bottom of branch's connection sleeve pipe has is welded with vertical section column
The horizontal solder side of connection, the normal of the horizontal solder side are overlapped with the axis of vertical section column；Branch's adapter sleeve
The top of pipe is the oblique weld face being connected with son field steel-pipe welding, the normal and son field steel pipe in the oblique weld face
Axis overlaps, and the oblique weld face is deviateed the inclination angle and son field steel pipe axis of branch's connection sleeve pipe axis and erected
Angle between straight section column axis is mutually remaining；Branch's connection sleeve pipe, son field steel pipe, one a pair of vertical section column three
Should；
The suspension column part is double-deck suspension column, including upper strata be welded to connect with vertical section column upper cover plate, the lower cover of lower floor
Plate and the floor being welded between upper and lower cover plates, have on the upper cover plate and the equal numbers of preformed hole of vertical section column, erect
Straight section column stretches to the upper surface of lower cover from the preformed hole of upper cover plate, and is welded to connect with lower cover；The upper cover plate
It is fixed by the pre-embedded anchoring bolts through both with lower cover.
Used as the preferred technical solution of the present invention, the son field steel pipe of the son field is vertebra shape pipe, its bottom diameter
More than top end diameter.
It is further preferred that the son field steel pipe has three, correspondingly, the vertical section column and branch's connection sleeve pipe

As Fig. 6 be 2 plum blossom pillar of embodiment according to the present invention overall structure diagram, when 3 length requirement of vertical section compared with
When big, the satisfactory vertical section of length can be spliced to form up and down using above vertical section 3 as vertical segment unit, it is adjacent
It is attached by straight section connector 6 between two sections straight section unit；Such as Fig. 7 and Fig. 8, the shape of straight section connector 6 with point
Prop up connector 2 approximate, be integrally formed steel-casting, including the straight section connection sleeve pipe 61 that surrounding is uniformly arranged one by one is with
Between straight section yoke plate 62 that branch's connection sleeve pipe is connected；The bottom of straight section connection sleeve pipe 61 is vertical with vertical section with top
The horizontal solder side that post is welded to connect.The length of the vertical section column of vertical section 3 is generally 13～40m, and the canalis spinalis of son field 1 is long
Degree is generally 4～23m.Such as Fig. 9, the clamp part 5 of the effect of closing up between the vertical section column side by side of vertical section 3, has been welded.
The installation method of above-mentioned plum blossom pillar is as follows：
Step one, material prepare：Including the preparation of vertical section column or canalis spinalis, and the preparation of all kinds of connectors etc.；
Step 2, selection specification identical vertical section column close up into vertical section 3：Can be between vertical section column side by side
If acting the clamp part 7 of the effect of closing up, when length is longer, several vertical sections 3 are spliced up and down as vertical segment unit, phase
It is attached by straight section connector 6 between adjacent two sections straight section unit；
Step 3, double-deck suspension column 4 is installed with vertical section 3：Vertical section column is stretched from the preformed hole of upper cover plate 41
Enter the upper surface to lower cover 43, and be welded to connect with upper cover plate 41 and lower cover 43 respectively；
Step 4, branched connection members 2 are fixedly connected with the son field steel pipe of son field 1：Branched connection members 2 each
A son field steel pipe, the axis of son field steel pipe are welded and fixed on the oblique weld face 212 on 21 top of branch's connection sleeve pipe
Overlap with the normal in oblique weld face 212；
Step 5, branched connection members 2 are welded and fixed with vertical section 3：By each the branch's connection sleeve pipe of branched connection members 2
