Prefabricated building steel structure high-efficiency connecting device

Abstract

This utility model discloses a high-efficiency connection device for prefabricated building steel structures, belonging to the field of steel structure connection technology. It includes an installation frame, a support platform, and a positioning mechanism. The support platform is fixedly connected to the side of the installation frame, and the positioning mechanism is also fixedly connected to the side of the installation frame. There are two sets of positioning mechanisms, symmetrically arranged on both sides of the installation frame. The beneficial effect is that, by setting up the positioning mechanism and support platform, when workers need to quickly connect the steel beam body, they first use a hoisting device to clamp the steel beam body to be connected onto the upper surface of the support platform. Then, by rotating a knob, the threaded column is rotated. With the cooperation of the threaded column and the threaded tube, the movable frame carrying the positioning block moves. Once the positioning block is engaged in the positioning groove, the worker only needs to stop rotating the knob, thus achieving the connection of the steel beam body.

Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and more specifically, to a high-efficiency connection device for prefabricated building steel structures. Background Technology

[0002] Steel structure buildings refer to buildings whose main load-bearing structure is made of steel, including steel beams, steel columns, steel trusses, and other components. Steel structure buildings are widely used in large public facilities, high-rise buildings, industrial plants, bridges, and other fields. In steel structure buildings, connection devices are a crucial component, as they can increase the overall stability and safety of the steel structure. The connection devices used in steel structure buildings include the following types: welded connections, bolted connections, riveting, high-strength bolt friction connections, pin connections, shear plate connections, etc.

[0003] When connecting steel beams, columns, and other components in high-rise buildings requires the use of connecting devices, the cumbersome operation affects the efficiency of workers in connecting the steel structure. To solve the above problems, we have introduced the following device. Utility Model Content

[0004] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an efficient connection device for prefabricated building steel structures, which has the feature of facilitating the connection of steel structures.

[0005] (2) Technical solution To achieve the above objectives, this utility model provides a high-efficiency connection device for prefabricated steel structures, including an installation frame, a support platform, and a positioning mechanism. The support platform is fixedly connected to the side of the installation frame, and the positioning mechanism is fixedly connected to the side of the installation frame. There are two sets of positioning mechanisms, symmetrically arranged on both sides of the installation frame. Each positioning mechanism includes a fixing plate, which is fixedly connected to the side of the installation frame. A bearing passes through the surface of the fixing plate, and a rotating shaft passes through the bearing. A knob is fixedly connected to the upper end of the rotating shaft, and a threaded column is fixedly connected to the lower end of the rotating shaft. A threaded tube is threadedly connected to the lower end of the threaded column, and a movable frame is fixedly connected to the lower end of the threaded tube. The movable frame matches the support platform, and a positioning block is fixedly connected to the lower surface of the movable frame. A steel beam body overlaps the upper surface of the support platform, and a positioning groove is formed on the upper surface of the steel beam body. The lower end of the positioning block is engaged in the positioning groove.

[0006] When using the high-efficiency connection device for prefabricated steel structures in this technical solution, by setting up a positioning mechanism and a support platform, when workers need to quickly connect the steel beam body, they first use a hoisting device to clamp the steel beam body to be connected onto the upper surface of the support platform. Then, by turning the knob, the threaded column is driven to rotate. With the cooperation of the threaded column and the threaded tube, the movable frame carrying the positioning block is moved. After the positioning block is engaged in the positioning groove, the workers only need to stop turning the knob, thereby achieving the connection of the steel beam body. At the same time, with the cooperation of the telescopic rod, the movable frame carrying the positioning block can be directionally moved.

[0007] Furthermore, a telescopic rod is fixedly connected to the upper surface of the movable frame, and the upper end of the telescopic rod is fixedly connected to the lower surface of the fixed plate. There are two sets of telescopic rods, which are symmetrically arranged on the upper end of the movable frame.

[0008] Furthermore, a limit frame is fixedly connected to the inner wall of the mounting frame.

[0009] (3) Beneficial effects In summary, this utility model has the following beneficial effects: 1. This high-efficiency connection device for prefabricated steel structures, through the setting of a positioning mechanism and a support platform, allows workers to quickly connect steel beams. First, workers use a hoisting device to clamp the steel beams to be connected onto the upper surface of the support platform. Then, by turning a knob, the threaded column is rotated. With the cooperation of the threaded column and the threaded tube, the movable frame carrying the positioning block is moved. Once the positioning block is engaged in the positioning groove, workers only need to stop turning the knob to connect the steel beams. At the same time, with the cooperation of the telescopic rod, the movable frame carrying the positioning block can be directionally moved. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0014] Example: The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0015] Please see Figure 1-3 This utility model provides a technical solution: a high-efficiency connection device for prefabricated steel structures, including an installation frame 1, a support platform 2, and a positioning mechanism 3. The support platform 2 is fixedly connected to the side of the installation frame 1, and the positioning mechanism 3 is fixedly connected to the side of the installation frame 1. There are two sets of positioning mechanisms 3, symmetrically arranged on both sides of the installation frame 1. The positioning mechanism 3 includes a fixing plate 301, which is fixedly connected to the side of the installation frame 1. A bearing 302 passes through the surface of the fixing plate 301, and a rotating shaft 303 passes through the bearing 302. A knob 304 is fixedly connected to the upper end of the rotating shaft 303, and a threaded column 305 is fixedly connected to the lower end of the rotating shaft 303. A threaded tube 306 is threadedly connected to the lower end of the threaded column 305, and a movable frame 307 is fixedly connected to the lower end of the threaded tube 306. The movable frame 307 matches the support platform 2. A positioning block 308 is fixedly connected to the lower surface of the movable frame 307. A steel beam body 4 overlaps the upper surface of the support platform 2. A positioning groove 5 is opened on the upper surface of the steel beam body 4, and the lower end of the positioning block 308 is engaged in the positioning groove 5.

[0016] By adopting the above technical solution, this efficient connection device for prefabricated building steel structure, through the setting of positioning mechanism 3 and support platform 2, allows workers to quickly connect the steel beam body 4. First, the workers use a hoisting device to clamp the steel beam body 4 to be connected onto the upper surface of the support platform 2. Then, by rotating knob 304, the threaded column 305 is driven to rotate. With the cooperation of threaded column 305 and threaded pipe 306, the movable frame 307 carrying positioning block 308 is moved. After the positioning block 308 is engaged in the positioning groove 5, the workers only need to stop rotating knob 304 to achieve the connection of steel beam body 4. At the same time, with the cooperation of telescopic rod 309, the movable frame 307 carrying positioning block 308 is able to move in a directional manner.

[0017] Specifically, a telescopic rod 309 is fixedly connected to the upper surface of the movable frame 307. The upper end of the telescopic rod 309 is fixedly connected to the lower surface of the fixed plate 301. There are two sets of telescopic rods 309, which are symmetrically arranged on the upper end of the movable frame 307.

[0018] Specifically, the inner wall of the mounting frame 1 is fixedly connected to the limit bracket 6.

[0019] The working principle of this utility model is as follows: When in use, the operator only needs to attach the mounting frame 1 to the upper end of the support column. Under the action of the limiting frame 6, the mounting frame 1 can be kept in a stable state. Then, the steel beam body 4 to be connected is attached to the upper surface of the support platform 2 using a hoisting device. Then, by rotating the knob 304, the threaded column 305 is driven to rotate. With the cooperation of the threaded column 305 and the threaded tube 306, the movable frame 307 carrying the positioning block 308 is moved. When the positioning block 308 is engaged in the positioning groove 5, the operator only needs to stop rotating the knob 304 to connect the steel beam body 4. At the same time, with the cooperation of the telescopic rod 309, the movable frame 307 carrying the positioning block 308 can be moved in a directional manner.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
