Description

Technical Field

[0001] This utility model belongs to the field of steel structure connection technology, and in particular relates to an assembly steel structure connection node. Background Technology

[0002] With the continuous development of modern building technology, steel structures have been widely used in high-rise buildings, large-span buildings and other fields due to their advantages such as being lightweight, high-strength, and fast in construction.

[0003] Currently, when assembling steel structure nodes, a crane is needed to lift the steel beams, and workers cannot directly make fine adjustments to align them with the holes for connection. This results in a long assembly time for steel structures, affecting work efficiency and increasing safety hazards for workers as the time spent working at height increases.

[0004] To address the aforementioned issues, this application proposes an assembly steel structure connection node. Utility Model Content

[0005] The purpose of this invention is to provide a connection node for assembling steel structures, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an assembly steel structure connection node, including steel columns and steel beams; The steel column has a seat plate on its side, and a fixing frame is installed on the upper and lower sides of the seat plate. A connecting rod is inserted in the fixing frame. The connecting rods on adjacent sides of the steel column are spliced ​​together to combine adjacent seat plates into one unit. A transition plate is inserted inside one end of the steel beam, and a hollow cylinder extends from the side of the seat plate, aligned with the support column on the upper side of the transition plate. A pull rope is inserted inside the hollow cylinder and detachably connected to the support column.

[0007] Preferably, the connecting rod is divided into left and right sections within the fixed frame, and the distance between the two sections is controlled by a spiral connection.

[0008] Preferably, a fixing cylinder is fixed to one side of the upper end of the seat plate, and a rope winding mechanism is provided inside the rope.

[0009] Preferably, the lower end of the pull rope is fixed with an adapter that connects to the end of the support column.

[0010] Preferably, the inner edge of the opening of the hollow cylinder is provided with a tapered slope to guide the support column into the interior of the hollow cylinder.

[0011] Preferably, the steel beam has a side plate extending outward from its end for connection and fixation with the seat plate and the steel column.

[0012] Preferably, a plug plate that is slidably connected to the adapter plate is installed below the steel beam by bolts.

[0013] This utility model has the following beneficial effects: After the adapter plate and steel beam are spliced ​​and fixed, the assembly of the pull rope and the support column can drive one end of the suspended steel beam to move to the predetermined position, thereby realizing the position fine adjustment to align with the screw hole, which facilitates the connection operation of workers and reduces their work difficulty. Furthermore, after the seat plate is installed, the connecting rods can be used to achieve linkage support between adjacent seat plates, thereby combining multiple seat plates into an integrated structure to achieve the effect of adapting to the installation of steel columns of different sizes.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Please see Figure 1-4 As shown, this utility model is an assembly steel structure connection node, including a steel column 1 and a steel beam 2; The steel column 1 has a seat plate 3 on its side. First, the seat plate 3 is installed on the steel column 1, and then the steel beam 2 is installed on the surface of the seat plate 3. The upper and lower ends of the seat plate 3 are equipped with fixing frames 31, which are hollow frame structures. The fixing frames 31 are equipped with connecting rods 311. The connecting rods 311 are composed of two rods. The connecting rods 311 on the adjacent sides of the steel column 1 are staggered vertically. After being fixed by bolts, the adjacent seat plates 3 are combined into one piece. One end of the steel beam 2 has a through groove at the top and bottom, and a transition plate 4 is inserted through the groove. A hollow cylinder 32 extends from the side of the seat plate 3 and is located below the upper fixing frame 31. When the steel beam 2 is installed on the surface of the seat plate 3, the support column 41 is aligned with the hollow cylinder 32. A pull rope 331 is inserted from the top of the hollow cylinder 32 into the interior for detachable connection with the support column 41, thereby pulling the suspended steel beam to finely adjust its position. Furthermore, the two adjacent ends of the connecting rod 311 are connected by a screw and a sleeve. The distance between the two rods is controlled by the screwing depth of the screw and sleeve, so that the connecting rods 311 on adjacent sides of the steel column 1 can be spliced ​​into one piece.

[0020] Furthermore, a fixed cylinder 33 is fixed on one side of the upper end of the seat plate 3, with the opening facing downwards. The pull rope 331 is equipped with a winding mechanism (the winding mechanism is a mature existing technology on the market and will not be described in detail here). After the pull rope 331 is connected to the support column 41, the support column 41 is driven to approach the hollow cylinder 32 by winding the pull rope 331.

[0021] Furthermore, the lower end of the pull rope 331 is fixed with an adapter 332, which can be a rotatable bolt, a pin, or other components that can achieve quick connection and fixation, for connecting and fixing to the end of the support column 41.

[0022] Furthermore, the inner edge of the opening of the hollow cylinder 32 is provided with a tapered slope 321. When the support column 41 approaches, the tapered surface of the tapered slope 321 guides the support column 41, enabling it to enter the interior of the hollow cylinder 32, thereby moving the steel beam 2 to the predetermined position to complete the positioning.

[0023] Furthermore, the end of the steel beam 2 extends outward with a side plate 21 for connecting and fixing to the seat plate 3 and the steel column 1.

[0024] Furthermore, a stopper plate 41 is provided below the steel beam 2, which is slidably installed inside the through groove at the lower end of the adapter plate 4, and then connected and fixed to the steel beam 2 by bolts, thereby fixing the adapter plate 4.

[0025] It is understood that this utility model can facilitate the positioning of the steel beam 2 during installation, enabling fine-tuning of its position to facilitate connection and fixation with the steel column 1. Furthermore, the multiple mounting plates 3 for the steel beam 2 can be used individually or combined into a single unit to form a linkage support, adapting to various specifications of steel columns 1.

[0026] A specific application of the operation process in this embodiment is as follows: First, the seat plate 3 is installed on the outside of the steel column 1 with bolts. Then, the ends of the two-way rods are joined together and placed inside the fixing frame 31 to form a complete connecting rod 311. Then, the adjacent connecting rods 311 in the two directions of the steel column 1 are connected and fixed with bolts, thereby connecting the adjacent seat plates 3 into a combined structure, which can adapt to the installation of steel columns 1 of different sizes. Further, the adapter plate 4 is inserted into the groove at the end of the steel beam 2 from top to bottom, and the plug plate 42 is inserted into the groove at the bottom of the adapter plate 4 below the steel beam 2, and then fixed with bolts. Then, the pull rope 331 is pulled outward and the adapter part 332 is connected and fixed with the support column 41. At this time, the pull rope 331 can be wound up to drive the support column 41 into the interior of the hollow cylinder 32, thereby positioning one end of the steel beam 2 and aligning the threaded hole on the side plate 21 with the seat plate 3 to facilitate the installation operation, reduce the difficulty of the work and ensure the installation accuracy.
