Description

Technical Field

[0001] The present application relates to the technical field of building engineering construction, and in particular to a steel structure rigid column-beam-column node structure. Background Art

[0002] A rigid column is a structure composed of components wrapped with concrete on the outside of steel sections, also known as a concrete rigid column or a concrete rigid column. Compared with traditional concrete structures, it has higher tensile, compressive and shear strengths, which can reduce the total weight of the entire building, reduce the pressure on the foundation and the construction cost of the foundation. At the same time, the rigid steel structure is convenient for on-site construction. In prefabricated steel structure buildings, steel structure rigid columns and beam-columns are extremely common.

[0003] The common connection between the rigid column and the beam column of the steel structure is fixed by bolts + welding, that is, a mounting plate is fixed by welding on each side wall of the rigid column, and the mounting plates are arranged vertically. There are two groups of mounting plates on each side wall of the rigid column, and the two groups of mounting plates are arranged vertically and parallel. A clamping cavity for clamping the horizontal beam column is left between the two groups of mounting plates. The horizontal beam columns are all in the form of an I-beam, and the width of the vertical part of the end side of the horizontal beam column is consistent with the width of the clamping cavity. A plurality of fixing holes are opened on the end side of the horizontal beam column, and corresponding mounting holes are also opened on the mounting plate. The fixing holes are correspondingly connected with the mounting holes. When installing the horizontal beam column and the rigid column, the technician first lifts the horizontal beam column to the side of the rigid column by hoisting, inserts the beam column into the clamping cavity, and makes the mounting hole correspond to the fixing hole. Then the technician needs to work at high altitude to screw in the bolts, so that the bolts pass through the mounting holes and the fixing holes in turn, and screw in the nuts at the free ends of the bolts. The beams, columns and rigid columns are initially fixed, and then the welding workers continue to work at high altitude to weld the fitting parts between the beams, columns and rigid columns, and the joints between the bolts and nuts, so as to ensure a stable connection between the rigid columns and the beams.

[0004] Regarding the above-mentioned related technologies, in the actual construction process, technical personnel are required to work at high altitude to tighten and weld bolts, which is difficult and dangerous to operate. In addition, at some corners, when the side of the rigid column is not perpendicular to the beam column, it is not easy to fix the rigid column and the beam column. Utility Model Content

[0005] In order to facilitate the construction workers to perform connection operations between rigid columns and beams and columns, reduce safety hazards, and facilitate the connection of beams and columns at corners with rigid columns at different angles, the present application provides a steel structure rigid column beam-column node structure.

[0006] The present application provides a steel structure rigid column-beam-column node structure adopts the following technical solution:

[0007] A steel structure rigid column beam-column node structure, comprising a cross-shaped rigid column, a beam-column and a connecting piece for connecting the rigid column to the beam-column, wherein the connecting piece comprises a mounting platform arranged on the rigid column, the mounting platform is in a truncated cone shape, an annular mounting groove is provided on the outer peripheral side of the mounting platform, the beam-column is movably inserted into the mounting groove, a fixing groove for inserting the rigid column is provided in the middle of the mounting platform, and a connecting component for stably connecting the mounting platform, the rigid column and the beam-column is also provided on the mounting platform.

[0008] By adopting the above technical solution, when connecting the rigid column and the beam column, the technicians first place the mounting platform on the rigid column and insert the rigid column into the fixing groove of the mounting platform. The annular mounting groove is convenient for the insertion and fixing of beam columns at any angle on the same horizontal plane. Then, the rigid column and the beam column are stably connected to the mounting platform through the provided connection components. The installation is simple and the problem of the rigid column and the beam column being difficult to connect at the corners due to the characteristics of the rigid column itself is reduced.

[0009] Optionally, the connecting component includes a limit plate slidably set on the mounting platform, a first limit hole is opened on the mounting platform, a second limit hole is opened on the beam column, the limit plate is slidably set in the first limit hole and movably inserted into the second limit hole, and the connecting component also includes a connecting member for making the limit plate stably located in the second limit hole.

[0010] By adopting the above technical scheme, when fixing the rigid column and the beam column, the technician first inserts the beam column into the installation groove so that the first limit hole corresponds to the second limit hole, and then the technician inserts the limit plate into the first limit hole and the second limit hole. Under the clamping action of the limit plate, the beam column is not easy to fall out of the installation groove, so that the relative position of the beam column and the mounting platform is kept stable, and the stable installation of the beam column and the mounting platform is achieved. At the same time, the connecting piece is arranged to make the limit plate stably located in the second limit hole, thereby improving the stability of the connection between the beam column and the rigid column.

[0011] Optionally, the connecting member includes a connecting rod slidably arranged on the mounting platform, a locking hole is opened in the middle of the limiting plate, and the connecting rod is movably arranged to pass through the locking hole.

[0012] By adopting the above technical solution, after the limit plate is inserted into the second limit hole, the technician slides the connecting rod to make the connecting rod pass through the locking hole of the limit plate. At this time, the limit plate is not easy to fall off the mounting table, so that the limit plate can be stably inserted into the second limit hole.

The connecting component also includes a positioning block movably inserted into the connecting groove, and the positioning block is plugged and adapted to the end side of the rigid column located in the connecting groove.

[0014] By adopting the above technical scheme, the cross-shaped fixing groove is convenient for inserting and fixing the rigid column. After the rigid column is inserted into the fixing groove, the technician inserts the positioning block into the connecting groove by knocking, and further locks the position of the rigid column. In the process of inserting the positioning block into the connecting groove, the elastically arranged clamping block is immersed in the positioning block under the action of the elastic compression force until the clamping block moves to the position corresponding to the positioning hole. At this time, the clamping block is inserted into the positioning hole under the action of the elastic restoring force, so that the rigid column is not easy to detach from the fixing groove, thereby realizing the stable installation of the rigid column and the mounting platform.

[0015] Optionally, the end side of the connecting rod away from the limiting hole is inclined, and the inclined side of the connecting rod is movably fitted and tightly pressed against the side wall of the positioning block.

[0016] By adopting the above technical solution, since the end side of the connecting rod is inclined, when the technician inserts the positioning block into the connecting groove, the positioning block and the end side of the connecting rod are pressed against each other, thereby pressing the connecting rod to slide, so that the connecting rod is inserted into the locking hole of the limit plate. After the clamping block is inserted into the positioning hole, the positioning tube is not easy to detach from the connecting groove, so that the connecting rod is not easy to slide in the direction away from the locking hole, thereby realizing stable locking of the connecting rod to the limit plate.

[0017] Optionally, a diagonal brace is rotatably connected to the bottom side of the mounting platform, and one end of the diagonal brace away from the mounting platform is rotatably connected to the side wall of the rigid column, one end of the diagonal brace is detachably connected to the mounting platform, and the other end of the diagonal brace is detachably connected to the rigid column.

[0018] By adopting the above technical solution, the arranged diagonal brace supports the bottom side of the mounting platform, thereby improving the stability of the mounting platform when connecting the rigid column with the beam column, so that after the beam column is inserted into the mounting groove, the mounting platform remains stable when supporting the beam column, thereby improving the bearing capacity of the mounting platform.

[0019] Optionally, a sliding block is slidably provided on the bottom side of the mounting platform, the sliding direction of the sliding block is consistent with the radial direction of the mounting platform, and the end of the diagonal brace away from the rotational connection with the rigid column is rotationally connected to the sliding block.

[0020] By adopting the above technical solution, the provided sliding block slides when the technicians install the beams, columns and rigid columns, thereby facilitating the installation and support of beams and columns of different heights.

[0021] Optionally, a first bolt hole is provided on the sliding block, a second bolt hole is provided on the beam column, and a positioning bolt is provided on the sliding block. The free end of the positioning bolt is movable through the first bolt hole and the second bolt hole in sequence, and a positioning nut is threadedly assembled on the free end of the positioning bolt, and the positioning nut is movably pressed against the bottom side of the beam column.

[0022] By adopting the above technical solution, after the beam column is inserted into the installation groove until the position of the first bolt hole corresponds to the position of the second bolt hole, the technician screws the positioning bolt to make the positioning bolt pass through the first bolt hole and the second bolt hole at one time, so that the relative position of the beam column and the mounting platform is kept constant, thereby achieving stable installation of the beam column, and by screwing the positioning nut, the positioning nut is pressed against the bottom side of the mounting platform, thereby achieving stable installation of the beam column and the mounting platform.
