Description

Technical Field

[0001] This application relates to the field of steel beam installation technology, and in particular to a beam-column connection structure. Background Technology

[0002] In the connection between steel columns and square steel beams, due to the need for temperature stress, it is often necessary to constrain vertical displacement and release horizontal displacement of the square steel beams in order to ensure reasonable stress distribution.

[0003] The existing technical solution involves installing a prefabricated support at the bottom of the square steel beam, welding the bottom of the beam to the support, and then installing a steel bracket below the support for further support. The steel bracket is welded integrally to the steel column. The prefabricated support can be custom-made to accommodate horizontal displacement, thus fulfilling the requirement for releasing the horizontal displacement of the square steel beam.

[0004] The existing technical solution has several drawbacks: The prefabricated support process is complex and costly. The internal structure of the prefabricated support is intricate, requiring fabrication and installation by specialized manufacturers, thus resulting in high costs. When installing prefabricated supports at the bottom of the square tube steel beam, steel brackets need to be installed below them for support, and these brackets must be welded to the steel column to meet the support requirements. This means that the dimensions of the prefabricated support and steel brackets occupy a certain amount of space under the square tube steel beam and affect aesthetics. Utility Model Content

[0005] To address the aforementioned issues, this technical solution provides a beam-column connection structure.

[0006] To achieve the above objectives, the technical solution is as follows:

[0007] A beam-column connection structure, including

[0008] steel columns;

[0009] A steel beam sleeve is welded horizontally to the side of the steel column; the steel beam sleeve is provided with a sleeve hole facing the horizontal direction;

[0010] A square steel beam is used to be inserted into the sleeve hole so that the steel beam sleeve is fitted onto it;

[0011] A sliding mechanism is provided between the steel beam sleeve and the square tube steel beam to allow the two to move horizontally relative to each other.

[0012] In the beam-column connection structure described above, the steel column is hollow and has a horizontal partition inside. The horizontal partition is laid along the cross-sectional direction of the steel column, and the position where the horizontal partition connects to the inner wall of the steel column corresponds to the position where the steel beam sleeve connects to the steel column.

[0013] In the beam-column connection structure described above, the two horizontal partitions are arranged vertically at intervals, and the positions where the two horizontal partitions connect to the inner wall of the steel column correspond to the connection positions between the upper and lower sides of the steel beam sleeve and the steel column, respectively.

[0014] In the beam-column connection structure described above, the ends of the square steel beam and the steel column are spaced apart.

[0015] The beam-column connection structure described above further includes a limiting mechanism for restricting the square tube steel beam from being pulled out of the steel beam sleeve.

[0016] As described above, in a beam-column connection structure, the limiting mechanism includes a movable groove penetrating the steel beam sleeve in a vertical direction, a through hole penetrating the square steel beam in a vertical direction, and a pin passing through the movable groove and the through hole. The movable groove is used to limit the movement range of the pin.

[0017] In the beam-column connection structure described above, the sliding mechanism includes a polytetrafluoroethylene layer disposed on the inner wall of the steel beam sleeve.

[0018] In the beam-column connection structure described above, the end of the steel beam sleeve is provided with a bevel, and the angle α between the bevel and the horizontal plane is an obtuse angle.

[0019] The beneficial effects of this application are:

[0020] This utility model provides a beam-column connection structure in which the steel beam sleeve is welded to the steel column as a whole, and a sliding mechanism is adopted between the square steel beam and the steel beam sleeve, which allows the square steel beam to slide back and forth, thereby releasing the horizontal displacement of the square steel beam.

[0021] 1. The connection method is simple, and there is no need to set up large-sized prefabricated supports and steel brackets. It does not affect the use of space under the square steel beam and can bring more usable space to the building.

[0022] 2. Compared with prefabricated supports and steel brackets, the pins and polytetrafluoroethylene in this application have lower costs and obvious economic advantages.

[0023] 3. Simple on-site installation. The technical solution of this application only requires conventional construction tools to meet the installation requirements, while existing technical solutions often require large hoisting equipment for prefabricated supports and steel brackets. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0025] Figure 1 This is a schematic diagram of the structure of this application;

[0026] Figure 2 for Figure 1 Top view. Detailed Implementation

[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] A beam-column connection structure, including

[0029] Steel column 1;

[0030] A steel beam sleeve 2 is welded to the side of the steel column 1 in a horizontal direction; the steel beam sleeve 2 is provided with a sleeve hole 21 facing the horizontal direction;

[0031] A square steel beam 3 is used to be inserted into the sleeve hole 21 so that the steel beam sleeve 2 is fitted onto it;

[0032] The sliding mechanism 4 is located between the steel beam sleeve 2 and the square tube steel beam 3 to allow the two to move horizontally relative to each other.

[0033] This utility model provides a beam-column connection structure in which the steel beam sleeve is welded to the steel column as a whole, and a sliding mechanism is adopted between the square steel beam and the steel beam sleeve, which allows the square steel beam to slide back and forth, thereby releasing the horizontal displacement of the square steel beam.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the steel column 1 is hollow, and a horizontal partition 11 is provided inside the steel column 1. The horizontal partition 11 is laid along the cross-sectional direction of the steel column 1, and the position where the horizontal partition 11 connects to the inner wall of the steel column 1 corresponds to the position where the steel beam sleeve 2 connects to the steel column 1. The steel beam sleeve is welded to the steel column, and the strength of the weld joint between the steel column and the steel beam sleeve is ensured by setting the horizontal partition inside the steel column.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the two horizontal partitions 11 are arranged vertically at intervals, and the positions where the two horizontal partitions 11 are connected to the inner wall of the steel column 1 correspond to the connection positions between the upper and lower sides of the steel beam sleeve 2 and the steel column 1, respectively.

[0036] Furthermore, as a preferred embodiment of this solution and not a limitation, the ends of the square tube steel beam 3 and the steel column 1 are spaced apart. The square tube steel beam and the steel beam sleeve are connected by the principle of inserting a smaller tube into a larger tube, but the insertion depth must be controlled. The square tube steel beam should not extend to the very end of the steel beam sleeve; otherwise, the function of releasing displacement and sliding back and forth cannot be achieved.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, it also includes a limiting mechanism 5 for restricting the square steel beam 3 from being pulled out of the steel beam sleeve 2.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation, the limiting mechanism 5 includes a movable groove 51 penetrating the steel beam sleeve 2 vertically, a through hole 52 penetrating the square tube steel beam 3 vertically, and a pin 53 passing through the movable groove 51 and the through hole 52. The movable groove 51 is used to limit the movement range of the pin 53. To prevent the square tube steel beam from being pulled out due to excessive horizontal displacement, a pin is needed for limiting and locking. The pin connects the square tube steel beam and the steel beam sleeve by setting the movable groove. The horizontal movable groove is designed to allow the square tube steel beam to slide back and forth to a certain extent while avoiding the risk of it being pulled out. To allow the square tube steel beam to slide back and forth more conveniently...

[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the sliding mechanism 4 includes a polytetrafluoroethylene (PTFE) layer attached to the inner wall of the steel beam sleeve 2. By attaching a smooth PTFE layer to the inside of the steel beam sleeve, the friction between the square steel beam and the steel beam sleeve is reduced, making it easier to achieve the required back-and-forth sliding motion.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the end of the steel beam sleeve 2 is provided with a bevel 22, and the angle α between the bevel 22 and the horizontal plane is an obtuse angle. Additionally, to facilitate the insertion of the square tube steel beam into the steel beam sleeve, a partial cut can be made on the side of the steel beam sleeve to form a bevel, which makes it easier to meet on-site installation requirements.

[0041] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
