Description

Technical Field

[0001] This utility model relates to the field of steel structure construction technology, and in particular to a protective structure for on-site steel structure construction. Background Technology

[0002] The protective structure used in on-site steel structure construction is an indispensable safety guarantee system in the steel structure installation process. Through a series of physical barriers and facilities (such as platforms, guardrails, safety nets, protective sheds, fire basins, etc.), it actively prevents major safety risks such as falls from heights, falling objects, and fires, and creates a relatively safe and controllable working environment for construction workers. It is a key element to ensure the safe, efficient and smooth progress of steel structure projects. Workers need to set up protective structures after the steel beams are hoisted. When installing protective structures on existing steel beams, the steel beams are usually hoisted first, then two bolts are used to position the steel plate, and then the steel pipes are welded onto the steel plate. This kind of protective structure installation process is cumbersome and dangerous, which greatly prolongs the construction of the protective tower and cannot meet the needs of the staff. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective structure for on-site steel structure construction.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A protective structure for on-site steel structure construction includes steel beams and multiple steel plates. The steel plates are connected to the steel beams by multiple bolts. A protective steel pipe is fixedly installed on the steel plate. An opening is formed in the protective steel pipe. An extension pipe is fixedly installed on the protective steel pipe. A placement groove is formed in the extension pipe. A rotating shaft is rotatably installed in the opening. A connecting rod is fixedly installed on the rotating shaft. A sliding groove is formed on the connecting rod. A stabilizing block is slidably connected in the sliding groove. A control mechanism for controlling the sliding of the stabilizing block is installed on the connecting rod.

[0005] Preferably, the control mechanism includes a second rotating shaft rotatably connected in a slide groove. The second rotating shaft is connected to the first rotating shaft via a belt drive assembly. A spur gear is fixedly installed at one end of the second rotating shaft. The stabilizing block has an opening that matches the spur gear. A rack is fixedly installed in the opening, and the spur gear meshes with the rack.

[0006] Preferably, the stabilizing block has a positioning opening, the placement groove has a limiting groove that matches the positioning opening, the positioning block is slidably connected in the limiting groove, the positioning block is slidably connected in the positioning opening, and multiple springs are fixedly installed between the positioning block and the limiting groove.

[0007] Preferably, a knob is fixedly installed at one end of the rotating shaft, and a protective sleeve is threaded onto the knob.

[0008] Preferably, the front end of the positioning block is installed with a beveled shape.

[0009] Preferably, the limiting groove has a pushing port, and a pull rod is slidably connected inside the pushing port, with one end of the pull rod fixedly installed on the positioning block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: By fixing the steel plate covering the width of the steel beam with more bolts, the protective steel pipes are then installed. At the same time, by rotating the connecting rods and stabilizing blocks on the protective steel pipes to connect with the extension pipes, the two protective steel pipes can be connected. The combination of the two can greatly improve the stability of the protective structure. In addition, this stabilizing structure does not require the steel beams to be hoisted and then welded for installation. It can be installed by workers first and then hoisted, thus speeding up the efficiency of on-site steel structure construction and protective erection and saving construction time.

[0016] Reference Figures 1-4 A protective structure for on-site steel structure construction, comprising: A steel beam 1 and multiple steel plates 2 are connected to the steel beam 1 by multiple bolts 3. A protective steel pipe 4 is fixedly installed on the steel plate 2. An opening 5 is opened on the protective steel pipe 4. An extension pipe 6 is fixedly installed on the protective steel pipe 4. A placement groove 7 is opened on the extension pipe 6. A rotating shaft 8 is rotatably installed in the opening 5. A friction sleeve is fitted on the rotating shaft 8. Therefore, in a vertical state, it can be stably placed in the opening 5 without shaking when not subjected to rotational force. A connecting rod 9 is fixedly installed on the rotating shaft 8. A sliding groove 10 is opened on the connecting rod 9. A stabilizing block 11 is slidably connected in the sliding groove 10. A control mechanism for controlling the sliding of the stabilizing block 11 is installed on the connecting rod 9. First, the steel plate 2 and the steel beam 1 are fixedly installed using bolts 3. Then, the protective steel pipe 4 is fixedly welded to the steel plate 2. At this time, the rotating shaft 8 is rotated, which drives the connecting rod 9 to rotate out of the opening 5. As the connecting rod 9 rotates, the control mechanism drives the stabilizing block 11 to slide from the slide groove 10 and continuously extend until the connecting rod 9 rotates from the vertical state to the horizontal state. At this time, the stabilizing block 11 in the connecting rod 9 slides into the placement groove 7 on the extension tube 6. The extension tube 6 supports the connecting rod 9 and the stabilizing block 11, completing the connection of the two protective steel pipes 4. Therefore, the stability of the protective structure can be greatly improved, and the structural strength can be increased. At the same time, if external operation is required, the connection of the two protective steel pipes 4 can be released by rotating the rotating shaft 8 in the opposite direction to reset the connecting rod 9. The operation is simple. The control mechanism includes a second rotating shaft 12 rotatably connected in the slide groove 10. The second rotating shaft 12 is connected to the first rotating shaft 8 via a belt drive assembly 13. The belt drive assembly 13 consists of two pulleys and a belt body, which is used to drive the rotation of the first rotating shaft 8, so that the second rotating shaft 12 rotates. A spur gear 14 is fixedly installed at one end of the second rotating shaft 12. A hole 15 matching the spur gear 14 is opened on the stabilizing block 11. A rack 16 is fixedly installed in the hole 15. The spur gear 14 meshes with the rack 16. When the first shaft 8 rotates, the second shaft 12 is driven to rotate through the belt drive assembly 13, which in turn drives the spur gear 14 fixedly installed on the second shaft 12 to rotate, thereby driving the meshing rack 16 to slide, so that the stabilizing block 11 slides in the groove 10. The stabilizing block 11 has a positioning port 17, and the placement groove 7 has a limiting groove that matches the positioning port 17. A positioning block 18 is slidably connected in the limiting groove. The positioning block 18 is slidably connected in the positioning port 17. Multiple springs 19 are fixedly installed between the positioning block 18 and the limiting groove. When the rotating shaft 8 drives the connecting rod 9 and the stabilizing block 11 to rotate to the lateral state, the positioning block 18 in the limiting groove is squeezed by the stabilizing block 11 and retracts into the limiting groove. When the positioning port 17 on the stabilizing block 11 matches the limiting groove, the positioning block 18 slides into the positioning port 17 under the elastic force of the spring 19, further completing the connection of the two protective steel pipes 4. A knob is fixedly installed at one end of the rotating shaft 8. A protective sleeve is threaded onto the knob. The operator can easily rotate the rotating shaft 8 by turning the knob. The front end of the positioning block 18 is installed with a bevel shape. The bevel installation of the positioning block 18 allows the positioning block 18 to be quickly compressed, making it easier to complete the positioning work. A push port is opened on the limiting groove. A pull rod 20 is slidably connected in the push port. One end of the pull rod 20 is fixedly installed on the positioning block 18. The positioning block 18 can be quickly pulled out from the positioning port 17 by pulling the pull rod 20, which facilitates the disassembly work.

[0017] In this utility model, the working principle is as follows: First, the steel plate 2 and the steel beam 1 are fixedly installed by bolts 3. Then, the protective steel pipe 4 is fixedly welded to the steel plate 2. At this time, the rotating shaft 8 is rotated, which drives the connecting rod 9 to rotate out of the opening 5. When the connecting rod 9 rotates, the belt drive assembly 13 drives the rotating shaft 12 to rotate, thus driving the spur gear 14 fixedly installed on the rotating shaft 12 to rotate, thereby driving the meshing rack 16 to slide, so that the stabilizing block 11 slides in the slide groove 10. The stabilizing block 11 slides out of the slide groove 10 and continuously extends until the connecting rod 9 rotates from a vertical state to a horizontal state. At this time, the stabilizing block 11 in the connecting rod 9 slides into the placement groove 7 on the extension tube 6. The extension tube 6 supports the connecting rod 9 and the stabilizing block 11, completing the connection of the two protective steel pipes 4. This greatly improves the stability and strength of the protective structure. If external operation is required, the connection of the two protective steel pipes 4 can be released by rotating the shaft 8 in the opposite direction to reset the connecting rod 9. The operation is simple. When the shaft 8 drives the connecting rod 9 and the stabilizing block 11 to rotate to the lateral position, the positioning block 18 in the limiting groove is squeezed by the stabilizing block 11 and retracts into the limiting groove. When the positioning port 17 on the stabilizing block 11 matches the limiting groove, the positioning block 18 slides into the positioning port 17 under the elastic force of the spring 19, further completing the connection of the two protective steel pipes 4.
