Description

Technical Field

[0001] This utility model relates to the field of building support technology, specifically a cantilevered triangular support frame. Background Technology

[0002] With the rapid advancement of urbanization in my country, urban space development continues to expand upwards, and high-rise and super high-rise buildings have become the mainstream form of modern urban architecture. These buildings need to simultaneously meet the dual requirements of structural construction and exterior decoration during the construction phase, and face challenges such as complex construction environments and tight process connections. This places extremely high demands on the adaptability, safety, economy, and environmental protection of the construction support system. Against this backdrop, cantilevered steel pipe coupler scaffolding has been widely used in the construction of high-rise and super high-rise buildings for a long time due to its strong adaptability to different building structures, load-bearing capacity that can meet conventional construction loads, and relatively simple erection and dismantling operations. It has become a core auxiliary facility for supporting structural pouring, component installation, and exterior decoration operations, playing an important role in ensuring construction progress and operational safety.

[0003] The layout of traditional cantilevered I-beam support systems must be strictly matched with the pre-set wall opening positions. Once the construction plan is determined, the planar layout and cantilever length of the frame are difficult to adjust. This makes it impossible to adapt to the needs of modern building facades with concave and convex shapes and changes in local construction areas such as bay windows and air conditioning panels. It is easy to have blind spots or over-support, requiring additional temporary supports, which further increases the complexity of construction. In summary, the traditional cantilevered support system currently used in the construction of high-rise and super high-rise buildings can no longer meet the needs of modern building construction. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that traditional cantilever support systems can no longer meet the needs of modern building construction, and to provide a cantilever triangular support frame with a completely new structural design.

[0005] This utility model is achieved through the following technical solution: A cantilevered triangular support frame, comprising: A rectangular frame and a support frame, with a U-shaped frame provided between the rectangular frame and the support frame.

[0006] The rectangular frame has slot 1 at the top and bottom of the side wall facing the U-shaped frame. The top of the side wall of the support frame is fixedly connected to a column. The top of the side wall of the U-shaped frame has slot 2. A support telescopic adjustment mechanism is provided between the U-shaped frame and the rectangular frame.

[0007] Furthermore, the support frame is a triangular support frame welded from square steel, vertical rods, and diagonal braces.

[0008] Furthermore, the two ends of the U-shaped frame extend into the inner cavity of the two slots and are slidably connected to their inner walls.

[0009] Furthermore, the insertion post extends into the inner cavity of slot two and is slidably connected to its inner wall.

[0010] Furthermore, the support telescopic adjustment mechanism includes a threaded rod rotatably connected to the inner wall of the U-shaped frame. One end of the threaded rod is threaded through one side wall of the rectangular frame and extends to the inner side of the rectangular frame.

[0011] Furthermore, a knob is fixedly connected to one end of the threaded rod inside the rectangular frame.

[0012] Furthermore, the rectangular frame and support frame have multiple plate limiting components.

[0013] Furthermore, the top of both side walls of the U-shaped frame and the support frame are fixedly connected with connecting side plates, and two adjacent connecting side plates are detachably fixedly connected by screws and nuts.

[0014] This utility model provides a cantilevered triangular support frame, which has significant and comprehensive technical advantages and practical value compared with the traditional cantilevered I-beam support system. It adopts a modular combination design of rectangular frame, support frame and U-shaped frame, and is equipped with a support frame telescopic adjustment mechanism, namely the adjustment structure composed of threaded rod and knob. By turning the knob, the threaded rod is driven to rotate, which in turn drives the U-shaped frame to slide along the slot of the rectangular frame, flexibly adjusting the relative distance between the rectangular frame and the support frame. It can easily achieve precise adaptation of the cantilever length, effectively solving the problems of the traditional system which requires matching the pre-set wall opening, resulting in fixed planar layout and inability to adapt to the construction needs of modern building facades with concave and convex shapes and special components such as bay windows and air conditioning panels. It avoids the cumbersome process of adding temporary supports due to support blind spots or excessive support, and greatly reduces the construction complexity.

[0015] This utility model provides a cantilevered triangular support frame. The support frame is formed by welding square steel, vertical rods and diagonal braces to form a triangular structure. The inherent stability of the triangle enhances the overall load-bearing capacity and anti-overturning performance. It is combined with a U-shaped frame that slides through slot one to the rectangular frame body, and a support frame that is positioned and connected to the U-shaped frame through slot two via insert columns. The U-shaped frame and the support frame are detachably fixed by connecting side plates and screws and nuts. This design not only ensures the firmness of the connection of each component, but also realizes the assembly and rapid installation. There is no need to reserve wall holes in the main structure, avoiding damage to the main building structure. It saves the process and cost of sealing wall holes after demolition in the traditional system, and also avoids the risk of leakage caused by incomplete sealing. Attached Figure Description

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment provides a cantilevered triangular support frame, including a rectangular frame 1 and a support frame 2. The rectangular frame 1 serves as the basic load-bearing frame of the cantilevered triangular support frame. The support frame 2 is a triangular support frame welded from square steel 21, vertical rods 22, and diagonal braces 23. As the core load-bearing component of the support system, it bears the load transmitted by the rectangular frame 1 and distributes the load to the main building structure. A U-shaped frame 3 is provided between the rectangular frame 1 and the support frame 2 to achieve a "flexible connection" between the rectangular frame 1 and the support frame 2. This ensures the stable transmission of the load and provides a sliding structural foundation for adjusting the cantilever length, avoiding the defect of the traditional system being "fixed and unadjustable". The two ends of the U-shaped frame 3 extend into the inner cavity of the two slots 4 and are slidably connected to their inner walls. The rectangular frame 1 and the support frame 2 have multiple plate limiting components 8.

[0021] The top and bottom of the side wall of the rectangular frame 1 facing the U-shaped frame 3 are provided with slots 4 to limit the sliding trajectory of the U-shaped frame 3 and provide vertical support for the U-shaped frame 3 to prevent the U-shaped frame 3 from detaching from the rectangular frame 1 during sliding or bearing. The top of the side wall of the support frame 2 is fixedly connected with a post 5 to position the relative position of the support frame 2 and the U-shaped frame 3, and to help transfer the load between the two to prevent the support frame 2 from lateral displacement relative to the U-shaped frame 3. The post 5 extends into the inner cavity of the second slot 6 and slides in connection with its inner wall. The top of the side wall of the U-shaped frame 3 is provided with a second slot 6 to receive the post 5 of the support frame 2, forming a positioning connection point between the support frame 2 and the U-shaped frame 3. A support telescopic adjustment mechanism 7 is provided between the U-shaped frame 3 and the rectangular frame 1.

[0022] The support telescopic adjustment mechanism 7 includes a threaded rod 71 that is rotatably connected to the inner wall of the U-shaped frame 3. One end of the threaded rod 71 is threaded through one side wall of the rectangular frame 1 and extends to the inner side of the rectangular frame 1. That is, the threaded rod 71 is threadedly connected to the side wall of the rectangular frame 1. A knob 72 is fixedly connected to one end of the threaded rod 71 located inside the rectangular frame 1. As the core driving component for adjusting the cantilever length, the knob 72 drives the U-shaped frame 3 to slide along the slot 4, thereby adjusting the relative distance between the rectangular frame 1 and the support frame 2 and thus achieving precise adjustment of the cantilever length.

[0023] The top of both sides of the U-shaped frame 3 and the support frame 2 are fixedly connected with connecting side plates 9. Two adjacent connecting side plates 9 are detachably fixed together by screws and nuts. The detachable connection design ensures the firmness of the connection between the two after adjustment, without affecting subsequent adjustment or disassembly operations.

[0024] The usage process of the cantilevered triangular support frame described in this embodiment is as follows: First, during the installation phase, the prefabricated support frame 2 is hoisted to the designated position. The two ends of the U-shaped frame 3 are slid into the slots 4 at the top and bottom of the side wall of the rectangular frame 1 facing the U-shaped frame 3. At the same time, the insert 5 at the top of the side wall of the support frame 2 is inserted into the slot 6 at the top of the side wall of the U-shaped frame 3. The U-shaped frame 3 and the top of the side walls of the support frame 2 are initially fixed with screws and nuts through the connecting side plates 9 at the top of the two side walls. The initial assembly of the rectangular frame 1, U-shaped frame 3 and support frame 2 is completed.

[0025] Next, the cantilever length adjustment stage begins. The knob 72, located inside the rectangular frame 1, is manually rotated on the threaded rod 71, causing the threaded rod 71 to rotate. Since one end of the threaded rod 71 is rotatably connected to the inner wall of the U-shaped frame 3 and the other end is threadedly connected to the side wall of the rectangular frame 1, the threaded transmission converts the rotational motion into the horizontal sliding of the U-shaped frame 3 along the slot 1 4. Then, through the cooperation of the slot 2 6 and the insert 5, the support frame 2 is moved, adjusting the relative distance between the rectangular frame 1 and the support frame 2 to match the required cantilever length. After adjustment, the position is locked by the self-locking property of the thread, and the screws and nuts connecting the side plate 9 are tightened.

[0026] During operation, the load of the upper frame is sequentially transferred to the rectangular frame 1, the U-shaped frame 3, and the support frame 2. The triangular structure of the support frame 2 uses the stability of triangles to distribute the load and resist lateral forces. The plate limiting components 8 on the rectangular frame 1 and the support frame 2 limit the position of the upper components to prevent displacement. When dismantling, first remove the upper frame, then loosen the screws and nuts connecting the side plates 9, and rotate the knob 72 in the opposite direction to separate the U-shaped frame 3 from the support frame 2. Dismantle each component in sequence for recycling and reuse.

[0027] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
