The first embodiment is as follows:
referring to fig. 1 and 2, for the utility model discloses a box cross-section frame post inner muff ring flange connected node, including upper prop 1, lower prop 2, ring flange 4 and inner skleeve 3, lower prop 2 and upper prop 1 are the cavity square column of looks adaptation, and the fixed cover in the inside of lower prop 2 is equipped with inner skleeve 3, and inner skleeve 3 one end is fixed in the inside of lower prop 2, and the other end stretches out the top of lower prop 2, and the part that inner skleeve 3 stretches out lower prop 2 inserts in the upper prop 1. The flange plate 4 is circumferentially welded on the end face of the bottom of the upper column 1 and the end face of the top of the lower column 2, threaded holes 41 are evenly formed in the flange plate 4 along four side edges of the flange plate 4 at intervals, the upper column 1 and the lower column 2 are mutually spliced, and the two flange plates 4 are connected through high-strength bolts 6.
The upper column 1 is positioned and connected by an inner sleeve 3 inserted therein, and the inner sleeve 3 is formed by splicing a four-sided straight plate 31 and a four-sided inclined plate 32. The straight plate 31 is attached to the inner wall of the lower column 2, the straight plate 31 and the straight plate 31 are connected by a swash plate 32, and the swash plate 32 is chamfered at a right angle of the inner sleeve 3. Because the right-angled cylinder wall can rub and clamp the inner wall of the lower column 2 in the insertion process, the operation is difficult, and the components can be scraped, and the inclined plate 32 is connected at the right-angled position of the inner sleeve 3 to form a straight chamfer, so that the inner sleeve 3 can be positioned and inserted more easily, and the damage to the components can be reduced.
According to the different connection modes of the inner sleeve 3 and the lower column 2, the processing and mounting method of the inner sleeve 3 can be divided into two types, one type is an integrated sleeve, one end of the integrated sleeve is inserted into the lower column 2 when the integrated sleeve is mounted and is connected with the lower column 2 through a bolt 6, and the other type is a split sleeve which is synchronously welded with the lower column 2 when the lower column 2 is processed.
This embodiment mainly describes the case where the integrated inner sleeve 3 is connected to the lower column 2 and the upper column 1 by the bolts 6.
When inner skleeve 3 and lower post 2 bolted connection, inner skleeve 3 can integrated into one piece, set up bolt hole 5 respectively in the position of every straight plate 31 and upper prop 1 and the laminating of lower post 2, according to the atress size of upper prop 1 and lower post 2, can increase or reduce the quantity of bolt hole 5, and upper prop 1 and lower post 2 set up perforation 21 in the position corresponding with bolt hole 5, and inner skleeve 3 passes through bolt 6 with lower post 2 and upper prop 1 respectively and is connected.
First, bolt holes 5 communicating with the inner cavity of the inner sleeve 3 are formed in the four straight plates 31 at the upper and lower portions of the inner sleeve 3, corresponding through holes 21 are formed in the upper portion of the lower column 2 and the lower portion of the upper column 1 at positions corresponding to the bolt holes 5, the inner sleeve 3 is inserted into the lower column 2 such that the bolt holes 5 are aligned with the through holes 21, bolts 6 are inserted into the through holes 21 and the bolt holes 5, and the inner sleeve 3 is fixed to the lower column 2 by tightening the bolts 6. The upper part of the inner sleeve 3 extends out of the flange 4 of the lower column 2 to wait for being connected with the lower part of the upper column 1. Then, the lower column 2 is installed in place, the upper column 1 is hung and sleeved in alignment with the extending upper part of the inner sleeve 3, a bolt hole 5 is formed in the joint part of the upper column 1 and the inner sleeve 3, and the lower part of the upper column 1 and the upper part of the inner sleeve 3 are connected together through a bolt 6. And finally, the flange plates 4 of the upper column 1 and the lower column 2 are butted, and the upper column 1 and the lower column 2 are connected into a whole through high-strength bolts 6. Need not to weld in the whole installation, easy operation, the detachability is strong.
When the upper column 1 and the lower column 2 are connected by the bolt 6, the connection can be performed by using the high-strength bolt 6, and the general bolt 6 needs to be screwed by a nut after being inserted into the bolt hole 5. In this embodiment, upper prop 1 forms the closed component with lower prop 2 butt joint back, can't stretch into the inner chamber with the instrument, and when screwing up external nut, the connecting shaft rotates, can't tighten fast, and the operation has the difficulty. Preferably, self-locking bolts can also be used. Rely on the extrusion to form the internal thread and form reliable locking threaded connection in downthehole, do not cooperate the nut to use, improve work efficiency, reach higher pretightning force, further strengthen the wholeness of box type post, improve the ability of shearing of component.
Furthermore, the stiffening ribs 8 can be welded on the flange plate 4 according to the actual situation on site, the stiffening ribs 8 are trapezoidal and are arranged in the circumferential direction of the upper column 1 and the lower column 2, and the joint of the vertical flange plate 4 and the column body is welded with the flange plate 4 and the column body, so that the local stability can be enhanced, and the torsion resistance of the component can be improved.
Furthermore, in order to facilitate the installation of the upper column 1, the upper end of the inner sleeve 3 is inclined towards the central axis of the inner sleeve 3 to form a closing-in opening 7, and the closing-in opening 7 is smaller than the opening of the upper column 1, so that the upper column 1 is conveniently sleeved on the inner sleeve 3.
