Embodiment
The utility model is described further with reference to the accompanying drawings and examples as follows：
Box beam column joint structure, as shown in Figures 2 and 3, including box column 1, box beam 2 and box bracket 3；The case
Type bracket 3 is the box-structure surrounded by bracket top flange plate 31, bracket bottom wing listrium 32 and two bracket webs 33；The case
Type beam 2 is the box-structure surrounded by beam top flange plate 21, lower flange of girder listrium 22 and two webs 23；The box bracket 3
One end is fixedly connected with box column 1, and the bracket web 33 of the other end docks with the web 23 of box beam 2；In the beam of box beam 2
Bottom wing listrium 22 is provided with insertion to the manhole 4 of the inner chamber of box beam 2, joint and the manhole of the box beam 2 with box bracket 3
4 pass through the intracavity inter-connection of box beam 2.
By being provided with insertion to the manhole 4 of the inner chamber of box beam 2, joint and the people of the box beam 2 with box bracket 3
Hole 4 is by the intracavity inter-connection of box beam 2, so that can pass through people in installation or the maintenance period of structure, operating personnel
Hole 4 smoothly enters the inside of box beam 2, and the joint for reaching box beam 2 and box bracket 3 is installed or overhauled, from
And facilitate the connection and maintenance of box beam 2 and box column 1.And by the way that manhole 4 to be arranged to the lower flange of girder listrium of box beam 2
22, the influence to box beam column joint structure stress performance is reduced, and box beam 2 or box bracket 3 can be avoided damage to
The diaphragm plate of inner chamber, simplify manufacturing procedure, while facilitate operating personnel's operation.During installation, first by box column 1 and box bracket
3 installation positioning, levelling, then box beam 2 is lifted to 3 corresponding position of box bracket, in-site installation personnel and passes through box beam
The manhole 4 of 2 lower flange of girder listrium 22 enters the inside of box beam 2, carries out box beam 2 and the docking operation of box bracket 3.
After docking and after inspection finishes for box beam 2 and box bracket 3, manhole 4 should be closed, with meet vision and
The requirement of the integrality of box beam 2.Therefore, it is preferred that the plugging plate 5 of closure manhole 4 is provided with, the plugging plate 5 is detachably installed
In lower flange of girder listrium 22.Because plugging plate 5 is flexibly connected with lower flange of girder listrium 22, when needing to use manhole 4, mobile plugging plate
5 expose manhole 4, move at manhole 4 plugging plate 5 after to be used and close manhole 4.
In the above-described embodiment, plugging plate 5 can with the mode connects for screw of lower flange of girder listrium 22, still, for the ease of installation
With dismounting, while the processing mounting holes of lower flange of girder listrium 22 in box beam 2 are avoided, it is preferred that the plugging plate 5 is overlapped under beam
The medial surface of flange plate 22.The medial surface of lower flange of girder listrium 22 is the one side that lower flange of girder listrium 22 is located at the inner chamber of box beam 2.Such as
This, when in use, directly moves plugging plate 5 in the inner chamber of box beam 2, plugging plate 5 is positioned over into lower flange of girder listrium 22 and is located at manhole 4
The position of side.Not only facilitate the assembly and disassembly of plugging plate 5, the lower flange of girder edge of box beam 2 itself can also be passed through after removal
Plate 22 temporary support plugging plate 5, plugging plate 5 shelves problem after solving dismounting.
Certainly, the lower surface of plugging plate 5 can be located at the side of the inner chamber of box beam 2 with lower flange of girder listrium 22 and flush, still,
When box beam column joint structure forced vibration, the inner chamber of box beam 2 on 5 easy edge of plugging plate is moved, and mistake occurs with manhole 4
Position, the phenomenon that manhole 4 is not blocked is caused to occur, in order to avoid above mentioned problem, it is preferred that the plugging plate 5 is embedded in manhole 4
It is interior, supporting plate 6 is provided with plugging plate 5, described one end of supporting plate 6 is fixedly connected with plugging plate 5, and the other end is overlapped under beam
Flange plate 22.
Plugging plate 5 is embedded in manhole 4, i.e., the shape of plugging plate 5 is identical with the shape of manhole 4, and the size of plugging plate 5 is omited
Less than the size of manhole 4, it is generally the case that the size of plugging plate 5 is less than the size 3-4mm of manhole 4, plugging plate 5 is put
Enter in manhole 4.Because plugging plate 5 is embedded in manhole 4, therefore, the hole wall of manhole 4 is just spacing to the circumference composition of plugging plate 5, avoids
Plugging plate 5 moves radially along manhole 4.And supporting plate 6 plays a part of plugging plate 5 being overlapped in lower flange of girder listrium 22.
In order to further improve visual effect and the integrality of box beam 2, under the lower surface and beam of the preferable plugging plate 5
The lateral surface of flange plate 22 flushes.The lateral surface of the lower flange of girder listrium 22 is relative with medial surface to be located at the inner chamber of box beam 2
The one side in outside.
In order to save material cost, it is preferred that the plugging plate 5 and the uniform thickness of lower flange of girder listrium 22.Due to plugging plate 5 and beam
The uniform thickness of bottom wing listrium 22, therefore, can be directly using the plate making closure cut down during processing manhole 4 from lower flange of girder listrium 22
Plate 5.
Manhole 4 can also be square, still, in order to pass through beneficial to operating personnel, it is preferred that the manhole 4 is rounded.And
Circular manhole 4 is compared with square manhole, more using avoiding stress concentration phenomenon.
Preferably, the bracket web 33 of the box bracket 3 is connected with the web 23 of box beam 2 by high-strength bolt
Connect.
