Description

Technical Field

[0001] This invention relates to the field of floor slab connector technology, and more specifically to a high-strength spatial steel structure. Background Technology

[0002] As the construction industry continues to demand higher standards for the aesthetics, safety, and construction efficiency of curtain wall structures, prefabricated steel structures, due to their advantages such as convenient installation, high strength, and industrial production capabilities, have gradually become an important component of modern building curtain wall systems. However, the awning structures currently used in curtain walls still have many shortcomings.

[0003] On the one hand, traditional awning windows often rely on simple hinges or sliding supports during opening or closing, lacking effective guiding and stabilizing mechanisms. This makes the windows prone to swaying and misalignment during state switching, affecting operational smoothness and safety. On the other hand, existing awning windows have relatively simple locking methods after opening or closing, mostly using manual pins or simple buckles. These are not only inconvenient to operate, but also prone to loosening and insecure positioning after long-term use, failing to meet the structural stability and reliability requirements of high-strength curtain wall systems. Furthermore, some awning windows are significantly affected by wind pressure or external forces when open, lacking effective locking support and posing safety hazards. Therefore, how to provide a steel structure for curtain walls that can maintain stable operation during awning window state switching and achieve reliable locking after switching has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-strength steel structure for space to solve the problems existing in the background art.

[0005] The present invention provides the following technical solution: a spatial high-strength steel structure, including a curtain wall, a window is provided on the curtain wall, a awning is provided at the window, a movable mechanism is provided at the top and bottom of the awning, a locking mechanism is provided at the top of the floor slab, and there are two locking mechanisms. The awning is provided with an open state and a closed state that can be switched between each other. The movable mechanism is used to connect the window and the awning and to ensure the stability of the awning during the state switching process. The locking mechanism is used to lock and fix the position of the awning after the state switching is completed.

[0006] Preferably, the movable mechanism includes a strip plate, a slider, and a stabilizing block. A sliding groove is provided at the top and bottom of the window. The strip plate is fixedly installed on the window sill. A connecting rod is provided between the strip plate and the stabilizing block.

[0007] Preferably, the slider is slidably installed in the groove, the stabilizing block is fixedly installed in the groove, a first fixing post is fixedly connected to the strip plate, a second fixing post is fixedly connected to the slider, and a third fixing post is fixedly connected to the stabilizing block.

[0008] Preferably, one end of the strip plate is rotatably connected to the second surface of the fixed column, one end of the connecting rod is rotatably connected to the first surface of the fixed column, and the other end of the connecting rod is rotatably connected to the third surface of the fixed column.

[0009] Preferably, the window is provided with a handle, and a fixing frame is also fixedly installed on the window. Two fixing frames are symmetrically arranged, and positioning posts are provided on the fixing frames.

[0010] Preferably, the locking mechanism includes a fixed rod, a guide frame, and a support frame. The fixed rod and the guide frame are fixedly connected. The support frame is fixedly installed on the top of the floor slab. A guide rod is fixedly connected to the support frame. The guide frame is sleeved on the surface of the guide rod. A compression spring is sleeved on the surface of the guide rod.

[0011] Preferably, a clamping block is fixedly connected to the fixing rod, and two clamping blocks are provided on each fixing rod.

[0012] Preferably, the clamping block is provided with a positioning groove that matches the positioning post, and the clamping block is also provided with a guide arc surface.

[0013] Preferably, a mounting shaft one is fixedly connected to the guide frame, a mounting shaft two is rotatably connected to the support frame, a rotating block is rotatably mounted on the surface of the mounting shaft one, and a mounting shaft three is fixedly connected to the rotating block.

[0014] Preferably, a rotating block is provided between the second mounting shaft and the third mounting shaft. The rotating block is fixedly installed on the surface of the second mounting shaft and rotatably installed on the surface of the third mounting shaft. A pedal is also fixedly connected to the surface of the second mounting shaft.

[0015] The beneficial effects of this invention are: In this invention, by setting a movable mechanism between the awning window and the curtain wall window, and setting a locking mechanism at the top of the floor slab, a smooth switching and reliable locking of the awning window between open and closed states is achieved, improving the structural stability, ease of operation, and safety of the curtain wall awning window system. The movable mechanism employs the linkage of a strip plate, slider, connecting rod, and stabilizing block. Utilizing the directional sliding of the slider within the groove and the rotational constraint of the connecting rod, the awning window is always controlled to a preset movement trajectory during state switching, effectively preventing deviation or swaying and ensuring the smoothness and accuracy of the switching action. Simultaneously, the locking mechanism employs the synergistic action of components such as clamping blocks, positioning columns, guide frames, compression springs, and pedals. The guiding arc surface enables the automatic insertion of the positioning column, and the elastic force of the compression spring drives the clamping block to automatically reset, forming a stable fit between the positioning column and the positioning groove, achieving instantaneous locking of the awning window position. Furthermore, when switching states is required, simply stepping on the pedal releases the clamping block through the linkage of the rotating block and the rotating block, making operation simple and effortless, and eliminating the need for tools during the switching process, thus improving ease of use. In addition, a locking mechanism is set up for both the open and closed states of the awning window, and locks it independently in both states. This ensures that the awning window can maintain a stable and reliable position under different working conditions, enhances the curtain wall system's ability to resist external loads such as wind pressure and vibration, and further improves the safety and durability of the overall structure.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 3 This invention provides a high-strength steel structure for space, including a curtain wall 1, a window 11 on the curtain wall 1, a cantilever window 2 at the window 11, a movable mechanism 3 at the top and bottom of the cantilever window 2, a locking mechanism 4 at the top of the floor slab, and two locking mechanisms 4. The cantilever window 2 has an open state and a closed state that can be switched between each other. The movable mechanism 3 is used to connect the window 11 and the cantilever window 2 and ensure the stability of the cantilever window 2 during the state switching process. The locking mechanism 4 is used to lock and fix the position of the cantilever window 2 after the state switching is completed.

[0030] Reference Figures 1 to 5 The movable mechanism 3 includes a strip plate 31, a slider 32, and a stabilizing block 33. A groove 12 is provided at the top and bottom of the window 11. The strip plate 31 is fixedly installed on the awning 2, and a connecting rod 34 is provided between the strip plate 31 and the stabilizing block 33. Through the coordinated arrangement of the strip plate 31, slider 32, and stabilizing block 33, a stable structural foundation is provided for the state switching of the awning 2, ensuring reliable connection of each component during movement.

[0031] The slider 32 is slidably installed within the slide groove 12, and the stabilizing block 33 is fixedly installed within the slide groove 12. A first fixing post 311 is fixedly connected to the strip plate 31, a second fixing post 321 is fixedly connected to the slider 32, and a third fixing post 331 is fixedly connected to the stabilizing block 33. One end of the strip plate 31 is rotatably connected to the surface of the second fixing post 321, and one end of the connecting rod 34 is rotatably connected to the surface of the first fixing post 311. The other end of the connecting rod 34 is rotatably connected to the surface of the third fixing post 331. Through the directional sliding of the slider 32 within the slide groove 12 and the rotational constraint of the connecting rod 34, the sill 2 is always controlled to follow a preset motion trajectory during state switching, effectively avoiding deviation or shaking and improving the smoothness and accuracy of the switching action.

[0032] A handle 21 is provided on the window 2, and a fixing bracket 22 is also fixedly installed on the window 2. There are two fixing brackets 22 arranged symmetrically, and a positioning post 221 is provided on the fixing bracket 22. The handle 21 is designed to facilitate the operator to apply force, and the fixing bracket 22 and the positioning post 221 provide a precise matching basis for the subsequent locking mechanism 4 to lock the position, thereby enhancing the positioning reliability of the window 2 in the open or closed state.

[0033] When in use, if the window 2 needs to be switched from the closed state to the open state, the operator grabs the handle 21 and pulls the window 2, so that the slider 32 slides from left to right along the slide groove 12, and the connecting rod 34 rotates around the axis of the fixed column 331. During this process, the positioning column 221 on the window 2 cooperates with the locking mechanism 4 on the right side, and the window 2 switches from the closed state to the open state. When the window 2 needs to be switched from the open state to the closed state, the operator grabs the handle 21 and pulls the window 2, so that the slider 32 slides from right to left along the slide groove 12, and the connecting rod 34 rotates around the axis of the fixed column 331. During this process, the positioning column 221 on the window 2 cooperates with the locking mechanism 4 on the left side, and the window 2 switches from the open state to the closed state.

[0034] In summary, during the switching between the closed and open states of the awning window 2, the precise guidance of the movement trajectory by the movable mechanism 3 ensures the smoothness and accuracy of the state transition. When the operator pulls the awning window 2 using the handle 21, the slider 32 in the movable mechanism 3 slides directionally along the slide groove 12, and the connecting rod 34 rotates around the axis of the fixed column 331, ensuring that the awning window 2 always moves along the preset path. This avoids deviation, shaking, or jamming during the switching process, improving the smoothness and controllability of the operation. Simultaneously, after the state transition is complete, the awning window 2 reliably engages with the locking mechanism 4, ensuring that the awning window 2 remains firmly in the preset position, effectively guaranteeing the overall structural stability. This design simplifies the operation process of the awning window 2 and eliminates the potential hazards of misalignment and insecure locking during state transitions in traditional awning windows from a structural perspective, meeting the comprehensive requirements of high-strength curtain wall systems for the safety, stability, and convenience of the awning window structure.

[0035] Reference Figures 1 to 10 The locking mechanism 4 includes a fixed rod 41, a guide frame 43, and a support frame 44. The fixed rod 41 and the guide frame 43 are fixedly connected. The support frame 44 is fixedly installed on the top of the floor slab, and a guide rod 441 is fixedly connected to the support frame 44. The guide frame 43 is sleeved on the surface of the guide rod 441, and a compression spring 442 is sleeved on the surface of the guide rod 441. Through the sliding guide cooperation between the guide frame 43 and the guide rod 441, and the setting of the compression spring 442, reliable elastic support is provided for automatic reset and locking, ensuring the timeliness and stability of the locking action.

[0036] A clamping block 42 is fixedly connected to the fixing rod 41, and two clamping blocks 42 are provided on each fixing rod 41. The clamping block 42 has a positioning groove 421, which matches the positioning post 221. The clamping block 42 also has a guide arc surface 422. The positioning post 221 can be automatically inserted by the setting of the guide arc surface 422, and a stable lock is formed by the engagement of the positioning groove 421 and the positioning post 221, which effectively improves the reliability of locking and the smoothness of operation.

[0037] A mounting shaft 431 is fixedly connected to the guide frame 43, and a mounting shaft 443 is rotatably connected to the support frame 44. A rotating block 45 is rotatably mounted on the surface of the mounting shaft 431, and a mounting shaft 451 is fixedly connected to the rotating block 45. A rotating block 46 is provided between the mounting shaft 443 and the mounting shaft 451. The rotating block 46 is fixedly mounted on the surface of the mounting shaft 443 and rotatably mounted on the surface of the mounting shaft 451. A pedal 47 is also fixedly connected to the surface of the mounting shaft 443. This arrangement, through the linkage of the pedal 47, the rotating block 46, and the rotating block 45, realizes foot-operated unlocking control of the locking mechanism 4, allowing easy release of the locked state without the need for tools, thus improving operational convenience.

[0038] In use, when the window 2 switches from the closed state to the open state, the positioning post 221 on the window 2 gradually contacts the guide arc surface 422 on the clamping block 42 of the right locking mechanism 4. During the movement of the positioning post 221 along the guide arc surface 422, due to the compression of the positioning post 221, the clamping block 42, the fixing rod 41 and the guide frame 43 slide along the guide rod 441 as a whole. The compression spring 442 contracts and increases its elastic force under the compression of the guide frame 43. When the positioning post 221 leaves the guide arc surface 422, the elastic force of the compression spring 442 is released. The elastic force of the compression spring 442 drives the clamping block 42, the fixing rod 41 and the guide frame 43 to reset as a whole. The positioning post 221 enters the positioning groove 421. The positioning post 221 and the positioning groove 421 cooperate with each other to lock and fix the position of the window 2. At this time, the window 2 switches from the closed state to the open state. When the window 2 needs to be switched from the open state to the closed state, the operator steps on the pedal 47 of the right locking mechanism 4 with his foot, causing the second mounting shaft 443 to rotate around its own axis. The rotation of the second mounting shaft 443 drives the rotating block 46 to rotate synchronously around the axis of the second mounting shaft 443. The rotation of the rotating block 46 drives the guide frame 43 to slide synchronously along the guide rod 441 through the third mounting shaft 451, the rotating block 45, and the first mounting shaft 431. The compression spring 442 contracts and increases its elasticity under the compression of the guide frame 43, and the positioning pin 221 separates from the positioning groove 421 on the clamping block 42 of the right locking mechanism 4. Afterwards, the worker grasps the handle 21 and pulls the window 2, causing the slider 32 to slide from right to left along the slide groove 12. The connecting rod 34 rotates around the axis of the fixed column 331. During this process, the positioning column 221 on the window 2 gradually contacts the guide arc surface 422 on the clamping block 42 of the left locking mechanism 4. As the positioning column 221 moves along the guide arc surface 422, due to the pressure from the positioning column 221, the clamping block 42, the fixed rod 41, and the guide frame 43 move as a whole along the guide arc surface 422. When the rod 441 slides, the compression spring 442 contracts and its elastic force increases under the pressure of the guide frame 43. When the positioning post 221 leaves the guide arc surface 422, the elastic force of the compression spring 442 is released. The elastic force of the compression spring 442 drives the clamping block 42, the fixing rod 41 and the guide frame 43 to reset as a whole. The positioning post 221 enters the positioning groove 421. The positioning post 221 and the positioning groove 421 cooperate with each other to lock and fix the position of the awning 2. At this time, the awning 2 switches from the open state to the closed state.

[0039] In summary, the ease of operation of the awning window 2 during the switching between closed and open states is greatly improved. Unlocking can be achieved simply by stepping on it, without any tools. Compared to traditional manual latches or buckles, this avoids problems such as wear, jamming, or operational inconvenience caused by long-term use. The reliability of unlocking and locking is significantly enhanced. The locking mechanism 4 uses a combination of elastic reset and a guiding structure, which automatically locks the awning window 2 after the state switch is completed. Once locked, it is firmly positioned and not easily loosened, effectively resisting interference from external loads such as wind pressure and vibration. The dual independent locking structure allows for separate control of the open and closed states of the awning window 2, ensuring a stable and reliable fixed position under different working conditions. This avoids the problems of insecure locking or state confusion that may occur with a single locking method, further improving the overall safety and structural stability of the curtain wall awning window system.

[0040] The working principle of this invention is as follows: When the window 2 needs to be switched from the closed state to the open state, the operator grasps the handle 21 and pulls the window 2, causing the slider 32 to slide along the slide groove 12 from left to right. The connecting rod 34 rotates around the axis of the fixed column 331. During this process, the positioning column 221 on the window 2 gradually contacts the guide arc surface 422 on the clamping block 42 of the right locking mechanism 4. As the positioning column 221 moves along the guide arc surface 422, due to the compression of the positioning column 221, the clamping block 42 and the fixed column 331... The rod 41 and the guide frame 43 slide along the guide rod 441 as a whole. The compression spring 442 contracts and increases its elastic force under the compression of the guide frame 43. When the positioning post 221 leaves the guide arc surface 422, the elastic force of the compression spring 442 is released. The elastic force of the compression spring 442 drives the clamping block 42, the fixing rod 41 and the guide frame 43 to reset as a whole. The positioning post 221 enters the positioning groove 421. The positioning post 221 and the positioning groove 421 cooperate with each other to lock and fix the position of the awning 2. At this time, the awning 2 switches from the closed state to the open state.

[0041] When the awning 2 needs to be switched from the open state to the closed state, the operator steps on the pedal 47 of the right locking mechanism 4 with his foot, causing the second mounting shaft 443 to rotate around its own axis. The rotation of the second mounting shaft 443 drives the rotating block 46 to rotate synchronously around the axis of the second mounting shaft 443. The rotation of the rotating block 46 drives the guide frame 43 to slide synchronously along the guide rod 441 through the third mounting shaft 451, the rotating block 45, and the first mounting shaft 431. The compression spring 442 contracts and increases its elasticity under the compression of the guide frame 43, and the positioning pin 221 separates from the positioning groove 421 on the clamping block 42 of the right locking mechanism 4.

[0042] Afterwards, the worker grasps the handle 21 and pulls the window 2, causing the slider 32 to slide from right to left along the slide groove 12. The connecting rod 34 rotates around the axis of the fixed column 331. During this process, the positioning column 221 on the window 2 gradually contacts the guide arc surface 422 on the clamping block 42 of the left locking mechanism 4. As the positioning column 221 moves along the guide arc surface 422, due to the pressure from the positioning column 221, the clamping block 42, the fixed rod 41, and the guide frame 43 move as a whole along the guide arc surface 422. When the rod 441 slides, the compression spring 442 contracts and its elastic force increases under the pressure of the guide frame 43. When the positioning post 221 leaves the guide arc surface 422, the elastic force of the compression spring 442 is released. The elastic force of the compression spring 442 drives the clamping block 42, the fixing rod 41 and the guide frame 43 to reset as a whole. The positioning post 221 enters the positioning groove 421. The positioning post 221 and the positioning groove 421 cooperate with each other to lock and fix the position of the awning 2. At this time, the awning 2 switches from the open state to the closed state.
