Treatment method and structure for deformation joint between steel structure columns
Technical Field
The invention belongs to the technical field of building structures, and particularly relates to a method and a structure for treating deformation joints among steel structure columns.
Background
The deformation joint needs to be arranged in a certain distance range due to overlarge size of the building, and for the steel structure building, due to the requirement of structural earthquake resistance, the width of the earthquake-resistant deformation joint of the steel structure is larger, and the larger the width of the joint is, the larger the adverse effect on daily use, safety, attractiveness and the like of the building is. Therefore, the deformation joint is constructed in the area range of the deformation joint so as to ensure the functional integrity, the use safety and the aesthetic requirements of the building.
The conventional treatment method is that a complete deformation joint structure closed loop (sky, ground and wall) is arranged on the ground, the cylindrical surface (wall surface) and the ceiling, so that the steel structure realizes fireproof isolation on each floor.
This conventional way makes the engineering volume of movement joint structure very big, and more troublesome is, the steel column all will arrive fire retardant coating, and the fire retardant coating of steel column is non-expansion type (thick type) fire retardant coating under the general condition, and thickness reaches more than 30mm, and after the steel column covers thick type fire retardant coating, the post (wall) face movement joint structure of traditional form just is very difficult to install, or can destroy the fire retardant coating layer, or the installation is insecure, has the potential safety hazard.
With the continuous development of building engineering, the proportion of assembly type buildings will be larger and larger, and the buildings with steel structures will be more and more. Therefore, the solution of this problem is also very urgent.

The method for processing the deformation joint between the steel structure columns is characterized in that a blocking structure is arranged at a beam-column joint of the deformation joint corresponding to the floor slab of each floor, the blocking structure is used for sealing the deformation joint between the two steel columns, and the sealing state between the two steel columns can be kept when the deformation joint deforms through deformation.
Furthermore, a deformation joint structure for between steel structure post is including overlapping first shrouding and the second shrouding that sets up, first shrouding and second shrouding all extend along the width direction of steel post, first shrouding and second shrouding one side respectively with two steel column connections, opposite side extend in opposite directions, the width of first shrouding and second shrouding is less than the width of deformation joint between two steel columns.
Further, a sealing sheet is arranged between the overlapped parts of the first sealing plate and the second sealing plate.
Furthermore, a sealing glue is filled between the first sealing plate and the second sealing plate.
Furthermore, a first flanging attached to the steel column in a folding mode is arranged on one side edge, connected with the steel column, of the first sealing plate, and a second flanging attached to the steel column in a folding mode is arranged on one side edge, connected with the steel column, of the second sealing plate.
Furthermore, a fireproof plug is arranged below the plugging structure, the fireproof plug is arranged below the plugging structure, and two sides of the fireproof plug are connected with the two steel columns respectively and extend along the width direction of the steel columns.
Furthermore, a water stop is arranged between the fireproof plugging and the plugging structure, and two sides of the water stop are connected with the two steel columns respectively and extend along the width direction of the steel columns.
Compared with the prior art, the invention has the following beneficial effects:
the plugging partition can be realized between the two steel columns only by paving the plugging structure between the two steel columns at the beam-column connection node corresponding to the floor slab, so that the requirements of deformation joint construction on two sides of the cylindrical surface of the steel column and the ceiling are reduced, and the engineering quantity of deformation joint plugging is reduced.
Due to the complicated shape molding requirements of the conventional deformation joint base, the commonly used aluminum alloy base meets the shape molding requirements, and it is difficult to realize the connection between the steel column and the aluminum alloy base through a simple structure.
Because this simple structure, consequently can use the galvanized steel sheet as the main constructional material of intercolumniation movement joint, can directly be connected through the welding between steel sheet and the steel column, and the fireproof material is scribbled again to the welding back, very big has made things convenient for the construction.
