Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a formwork support structure for the upper beam of a large-span Y-shaped column. Background Technology

[0002] In modern building construction, especially in the support of formwork for large-span beams, Y-shaped columns, as a crucial structural component, often face complex construction challenges. Traditional support systems typically rely on foundational components such as uprights and support beams to bear the weight of the formwork and structural loads. However, due to the complex shape and immense weight of large-span beams, the design of traditional support systems often faces issues such as space constraints, structural interference, and safety hazards. During the construction of large-span beam formwork, the mutual interference between the support uprights and structures such as Y-shaped columns and transfer beams often leads to ineffective stability of the support system, resulting in uneven support, formwork deformation, and reduced load-bearing capacity. Furthermore, the arrangement of support uprights in traditional support systems is not flexible enough, making precise adjustments in different areas according to construction requirements difficult. This results in long construction cycles and a large amount of repetitive work, increasing construction costs and safety risks.

[0003] While some existing support systems have made improvements in their design, they still cannot fundamentally solve the problem of interference between the support poles and the structure. Traditional support systems typically lack sufficient obstacle avoidance space, causing the support poles to come into contact with Y-shaped columns, beam formwork, or other structures during construction, further exacerbating the local instability of the support system. Even with a zoned layout, problems such as mutual interference between support poles and uneven load distribution often exist, resulting in unsatisfactory support performance. In summary, existing support technologies often fail to meet the requirements for support independence, safety, and flexibility in challenging construction environments, leading to frequent problems during construction. Therefore, there is an urgent need for an innovative support structure and method that can effectively solve these technical challenges. Utility Model Content

[0009] Both of the aforementioned support component arrangement areas are provided with several sets of vertically erected beam panel support uprights, and the surfaces of each set of beam panel support uprights are connected to several beam panel support crossbars.

[0010] Furthermore, the auxiliary beam support columns of each group and the beam panel support columns of each group are alternately arranged in the support component arrangement area.

[0011] Furthermore, the surface of the second transverse transition beam is connected to a load-bearing main beam bottom support, the surface of the second auxiliary beam support crossbar is connected to an auxiliary beam bottom support, and the surface of the beam panel support crossbar is connected to a beam panel template bottom support.

[0012] Furthermore, several of the auxiliary beam support columns and beam panel support columns are arranged in the gap between adjacent second transverse transition beams and longitudinal transition beams.

[0013] Furthermore, the top of each of the transfer beam support upright, beam panel support upright, and auxiliary beam support upright is provided with a fixing block. The fixing block on the transfer beam support upright is used to stably connect the transfer beam support upright and the first transverse transfer beam. The fixing block on the beam panel support upright is used to stably connect the beam panel support upright and the beam panel support crossbar. The fixing block on the auxiliary beam support upright is used to stably connect the auxiliary beam support upright and the first auxiliary beam support crossbar.

[0014] Furthermore, the outer sides of several transfer beam support columns, beam panel support columns, and auxiliary beam support columns in the two support component arrangement areas are all connected to a bottom reinforcement frame.

[0015] Furthermore, the sides of the support poles for each beam panel are connected to a top reinforcement frame.

[0016] A method for supporting the formwork of a large-span Y-shaped column upper beam support structure, the method comprising the following steps:

[0017] Step S1: Determine the location of the Y-shaped column and mark the arrangement areas of the supporting components on both sides to ensure symmetrical arrangement on both sides;

[0018] Step S2: Install several sets of transfer beam support columns vertically, and leave a preset obstacle avoidance area between the transfer beam support columns to avoid contact with the Y-shaped column;

[0019] Step S3: Connect the end of the support pole of each set of transfer beams to the first transverse transfer beam, and fix the longitudinal transfer beam on the first transverse transfer beam;

[0020] Step S4: Connect the two ends of the longitudinal transfer beam to the second transverse transfer beam to complete the construction of the support frame;

[0024] Step S8: Tie the beam reinforcement, pour concrete and cure it as required, and finally conduct a quality inspection of the support structure to ensure the stability of the support system.

[0025] The formwork support structure for the upper beam of a large-span Y-shaped column provided by this utility model has the following beneficial effects:

[0026] It can effectively solve several technical problems existing in traditional support systems, especially in the application of formwork construction for large-span beams. First, through a rationally designed support pole system, the individual support poles do not interfere with each other, and the support poles maintain a preset obstacle avoidance zone with the Y-shaped columns and transfer beams. This avoids the instability and safety hazards caused by contact or interference between the poles and the structure in traditional support systems, ensuring the independence and safety of the support system.

[0027] Secondly, the utility model employs a zoned support pole system, ensuring effective support for the beam formwork, main load-bearing beams, and auxiliary beams in different areas. Furthermore, different types of support poles (such as transfer beam support poles, beam panel support poles, and auxiliary beam support poles) are arranged without interference, each capable of independently bearing the load of its respective section, greatly improving the stability and safety of the overall support system. This approach not only improves construction efficiency but also effectively reduces the risk of deformation or accidental displacement during construction.

[0028] Furthermore, this invention, through a precise support system and a rational mechanical layout, reduces repetitive work and construction time, saving significant manpower and resources, and lowering overall construction costs. This method is highly flexible and can be widely applied to the support of various complex structures and large-span beams, especially suitable for the construction of large-span structures such as high-rise buildings, bridges, and factories, demonstrating promising market application prospects and widespread value. In summary, the support structure and method of this invention exhibit significant advantages in improving construction safety, stability, efficiency, and cost control, possessing strong application value and broad prospects.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0038] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0039] like Figures 1-7 As shown in the figure, the present invention provides a formwork support structure for the upper beam of a large-span Y-shaped column, including two support component arrangement areas 21, which are symmetrically arranged on both sides of the Y-shaped column 18, and the Y-shaped column 18 is set on the ground 20.

[0040] Several sets of vertically erected transfer beam support columns 15 are provided in both support component arrangement areas 21, and a preset obstacle avoidance area is left between the transfer beam support columns 15 in the two support component arrangement areas 21.

[0041] Each set of transition beam support poles 15 is connected to a first transverse transition beam 14 at its end, and several first transverse transition beams 14 on each set of transition beam support poles 15 are connected to several longitudinal transition beams 13 on their surfaces. Several longitudinal transition beams 13 in the two support member arrangement areas 21 are connected to several second transverse transition beams 12 on their surfaces.

[0042] In both support component arrangement areas 21, there are several sets of vertically erected auxiliary beam support poles 6, and the surface of each set of auxiliary beam support poles 6 is connected to several first auxiliary beam support crossbars 5. The surfaces of several first auxiliary beam support crossbars 5 on the same set of auxiliary beam support poles 6 are connected to several second auxiliary beam support crossbars 7.

[0043] Each of the two support component arrangement areas 21 is equipped with several sets of vertically erected beam panel support columns 11, and the surface of each set of beam panel support columns 11 is connected to several beam panel support crossbars 10. Each set of auxiliary beam support columns 6 and each set of beam panel support columns 11 are arranged alternately in the support component arrangement area 21. The auxiliary beam support columns 6 and beam panel support columns 11 are all arranged in the gap between adjacent second transverse transfer beams 12 and longitudinal transfer beams 13.

[0044] The surface of the second transverse transition beam 12 is connected to the load-bearing main beam bottom support 8, the surface of the second auxiliary beam support crossbar 7 is connected to the auxiliary beam bottom support 4, and the surface of the beam panel support crossbar 10 is connected to the beam panel template bottom support 9.

[0045] In one embodiment of this utility model:

[0046] The support structure provided in this embodiment of the utility model is an innovative support system designed to meet the construction needs of the upper beam formwork of large-span Y-shaped columns. This system not only solves the problems of stability, ease of installation, and safety of traditional formwork supports in large-span construction, but also takes into account compatibility with Y-shaped columns, effectively avoiding collisions and interference between the support uprights and the column, ensuring structural safety and construction efficiency during the construction process.

[0047] In this invention, the support structure is symmetrically arranged on both sides of the Y-shaped column 18 via two support component arrangement areas 21. This symmetrical layout allows the support system to distribute the load generated during construction more evenly and ensures the overall stability of the structure. The selection of the support component arrangement areas 21 creates a reasonable construction space on the ground 20 and is symmetrically arranged through the doorway areas 19 on the Y-shaped column 18. Through this symmetrical arrangement, the support system can meet the installation requirements of large-span beam formwork without contacting the Y-shaped column, avoiding the installation inconvenience and construction interference problems that may occur with traditional support structures due to contact with the column.

[0048] In the support system, all support columns (such as transfer beam support columns 15, beam panel support columns 11, and auxiliary beam support columns 6) are independently installed and do not interfere with each other. The number of transfer beam support columns 15 in each group is generally set to 3 to 4, the number of beam panel support columns 11 is set to 4 or 6, and the number of auxiliary beam support columns 6 is set to 4 or 6. This independent design greatly improves the flexibility and adaptability of the support system, avoids mutual interference between different support components, and ensures that each support column can accurately perform its respective support function, thus ensuring the overall stability of the support system.

[0049] This independently designed structure effectively prevents the supporting uprights from colliding with each other and maintains sufficient distance from the transfer beams (such as the first transverse transfer beam 14, the longitudinal transfer beam 13, and the second transverse transfer beam 12), thus avoiding deformation or instability caused by contact between the supporting uprights and the beam body. This independence between the uprights ensures that during construction, they can be freely adjusted and positioned according to the construction progress without being affected by other components, and can flexibly adapt to the formwork construction needs of beams with different spans or heights.

[0050] Within the support system framework, the transfer beam support uprights 15 are connected via first transverse transfer beams 14. Multiple first transverse transfer beams 14 on each set of transfer beam support uprights 15 are then connected to second transverse transfer beams 12 via longitudinal transfer beams 13. This combined effect of the beam-frame structure allows the support system to effectively distribute the load from the beam formwork, avoiding localized load concentration and enhancing the overall compressive strength and stability of the support system. Simultaneously, the pre-designed obstacle avoidance zones between the transfer beam support uprights 15 further prevent contact between the support uprights and the Y-shaped columns 18, thereby improving the safety of the support system.

[0051] Furthermore, the auxiliary beam support columns 6 and beam panel support columns 11 in the support system are alternately arranged in each support component arrangement area 21. The first auxiliary beam support crossbar 5 and the second auxiliary beam support crossbar 7 on each set of auxiliary beam support columns 6 jointly support the auxiliary beam 3, and the connection between the auxiliary beam bottom support 4 and the auxiliary beam ensures the stable support function of the auxiliary beam. Meanwhile, the beam panel support crossbar 10 on each set of beam panel support columns 11 supports the beam panel formwork 1, ensuring stable positioning of the beam formwork during construction and avoiding construction problems caused by formwork deformation or positional displacement. The alternating arrangement of the two sets of support columns 6 and 11 rationally distributes the support load, enhancing the stability and uniformity of the support structure.

[0052] Each set of support poles establishes a tight support connection with the load-bearing beams, auxiliary beams, and beam panel formwork through base supports. The main load-bearing beam base support 8 supports the main load-bearing beam 2, the beam panel formwork base support 9 supports the beam panel formwork 1, and the auxiliary beam base support 4 supports the auxiliary beam 3. This base support design not only effectively distributes the weight generated by the beam formwork and beam structure but also ensures balanced stress distribution throughout the entire support structure, further enhancing the reliability and construction safety of the support system.

[0053] Through the aforementioned innovative design, the support structure provided by this utility model has several significant advantages. First, the independently set support pole system greatly improves the system's flexibility and stability, avoiding mutual interference between different support components. Second, the rationally designed obstacle avoidance area ensures that the support system does not contact the Y-shaped column, preventing instability and safety hazards caused by contact during construction. Furthermore, the combined effect of multiple support levels gives the entire support system high load-bearing capacity and compressive strength, enabling it to adapt to the needs of different construction conditions.

[0054] This support structure can effectively support large-span beam formwork, and has broad application prospects, especially under complex shapes and special construction conditions. With the increasing demand for large-span, complex structure formwork support in the construction industry, the support system provided by this invention will play a vital role in related engineering fields, such as bridges, high-rise buildings, and industrial plants, involving large-span construction. This system not only improves construction efficiency and reduces construction costs, but also ensures the safety and precision of the construction process, which is of great significance to promoting the development of construction technology.

[0055] In this embodiment, the top ends of the transfer beam support column 15, the beam panel support column 11, and the auxiliary beam support column 6 are all equipped with fixing blocks. The function of each fixing block is to ensure a stable connection between the support column and the crossbeam it is connected to, thereby enhancing the robustness and reliability of the support structure.

[0056] Specifically, the fixing blocks on the transfer beam support column 15 are used to stably connect the transfer beam support column 15 to the first transverse transfer beam 14. Through this connection, the transfer beam support column 15 can provide support for the transverse transfer beam, ensuring that the transfer beam system will not shift or deform during the support of large-span formwork, thereby ensuring the stability of the overall structure.

[0057] The fixing blocks on the beam panel support uprights 11 are used to stably connect the beam panel support uprights 11 to the beam panel support crossbars 10. This connection effectively supports the beam panel formwork 1, preventing displacement or subsidence during construction and ensuring the accuracy and safety of the formwork system. This structural design gives the beam panel support system higher stability under stress, enabling it to better withstand the loads of the superstructure and ensuring safe and reliable formwork construction.

[0058] For the auxiliary beam support column 6, the fixing block at its top is used to stably connect the auxiliary beam support column 6 to the first auxiliary beam support crossbar 5. This connection ensures the stability of the auxiliary beam support system, allowing the auxiliary beam to be evenly stressed during support and avoiding displacement or deformation caused by uneven support. In addition, the connection between the first auxiliary beam support crossbar 5 and the second auxiliary beam support crossbar 7 further enhances the bending and compressive resistance of the entire auxiliary beam support system.

[0059] The design of these fixing blocks not only ensures a firm connection between each support column and the beam, but also improves the seismic resistance and safety of the entire support structure, preventing structural instability or accidents during construction caused by weak connections. These connection structures, while ensuring construction accuracy, also make the entire support system simpler and safer during construction.

[0060] In this embodiment, a bottom reinforcement frame 16 is connected to the outer sides of several transfer beam support columns 15, beam panel support columns 11, and auxiliary beam support columns 6 in the two support component arrangement areas 21. As an important component of the support system, the bottom reinforcement frame 16 plays a role in enhancing the stability of the support and improving safety.

[0061] Specifically, the bottom reinforcement frame 16 connects the transfer beam support poles 15, the beam panel support poles 11, and the auxiliary beam support poles 6 together to form a stable overall support structure. Since these support poles are located in different positions and have different force directions, the bottom reinforcement frame 16 can effectively connect the outer sides of these poles, preventing the individual support poles from shifting or deforming due to uneven force during construction, thereby ensuring the stability of the entire support structure.

[0062] The bottom reinforcement frame 16, by connecting the various support columns laterally, further disperses the force borne by each support column, enhancing its overall resistance to lateral displacement. When the beam formwork is subjected to stress during construction, the bottom reinforcement frame 16 can effectively transfer the force to the ground 20, reducing the pressure borne by the support columns alone, thereby reducing the risk of local instability or tilting.

[0063] In addition, the bottom reinforcement frame 16 also has a certain degree of seismic resistance, which can effectively improve the stability and safety of the support system under earthquakes or other external loads. Due to its simple structure and convenient construction, the bottom reinforcement frame 16 can effectively save construction time and costs while improving the compressive and bending resistance of the overall support system.

[0064] In summary, the bottom reinforcement frame 16, by connecting the various support uprights, not only enhances the stability of the support structure and prevents mutual interference and displacement between the support uprights, but also improves the seismic resistance and safety of the entire support system, providing a reliable guarantee for the support of the upper beam formwork of the large-span Y-shaped column.

[0065] In this embodiment, the sides of each set of beam panel support poles 11 are connected to a top reinforcement frame 17.

[0066] Each set of beam panel support uprights 11 is connected to a top reinforcement frame 17 on its side. As a key component of the support structure, the top reinforcement frame 17 plays a role in enhancing the stability of the support and improving the overall rigidity of the structure.

[0067] Specifically, the top reinforcement frame 17 connects the sides of each group of beam panel support uprights 11, ensuring coordination and cooperation among the uprights. Since the beam panel support uprights 11 bear the weight of the beam panel formwork 1 and the construction load, the top reinforcement frame 17 effectively enhances their resistance to lateral forces, preventing the support uprights from bending, tilting, or experiencing uneven stress during the stress process, thereby improving the overall stability of the support system.

[0068] The design of the top reinforcement frame 17 allows for a good distribution of force between the vertical and horizontal directions in the support structure, enabling each support column to bear the pressure evenly. It effectively connects and fixes the top of the beam panel support columns 11, reducing the swaying or displacement of the support columns caused by external forces during construction and ensuring the vertical stability of the support system.

[0069] Furthermore, the top reinforcement frame 17 also possesses certain wind and earthquake resistance. Under dynamic loads such as wind loads or earthquakes, it can effectively improve the support system's resistance to disturbances and reduce the risk of instability of the support poles due to changes in the external environment. The reinforcement frame itself has a simple structure and is easy to install, providing great convenience for the construction site while also enhancing the safety of the overall support system.

[0070] In summary, the top reinforcement frame 17 plays multiple roles in the support system, such as enhancing the stability of the support uprights, improving the load-bearing capacity, and preventing support displacement. This ensures the safety and stability of the large-span beam formwork support structure and provides reliable protection for the support system during construction.

[0071] This utility model also provides a support method for the formwork support structure of the upper beam of a large-span Y-shaped column, which specifically includes the following steps:

[0072] Step S1: Determine the position of the Y-shaped column 18 and mark the support member arrangement areas 21 on both sides to ensure symmetrical arrangement on both sides;

[0073] Step S2: Install several sets of transfer beam support poles 15 vertically, and leave a preset obstacle avoidance area between the transfer beam support poles 15 to avoid contact with the Y-shaped column 18;

[0074] Step S3: Connect the end of each set of transition beam support poles 15 to the first transverse transition beam 14, and fix the longitudinal transition beam 13 on the first transverse transition beam 14;

[0075] Step S4: Connect the two ends of the longitudinal transfer beam 13 to the second transverse transfer beam 12 to complete the construction of the support frame;

[0076] Step S5: Install several sets of auxiliary beam support uprights 6 vertically, and fix the first auxiliary beam support crossbar 5 and the second auxiliary beam support crossbar 7 on the auxiliary beam support uprights 6;

[0077] Step S6: Install several sets of beam panel support uprights 11 vertically, and fix beam panel support crossbars 10 on the beam panel support uprights 11;

[0078] Step S7: Build the beam formwork, connect the bottom support 9 of the beam formwork to the support crossbar 10 of the beam panel, connect the bottom support 8 of the main load-bearing beam to the second transverse transition beam 12, and connect the bottom support 4 of the auxiliary beam to the support crossbar 7 of the second auxiliary beam to ensure that all formwork is stable.

[0079] Step S8: Tie the beam reinforcement, pour concrete and cure it as required, and finally conduct a quality inspection of the support structure to ensure the stability of the support system.

[0080] In the above method, the entire construction process effectively solves a series of technical problems in the formwork support of large-span beams through precise support system design and efficient construction steps.

[0081] First, during the construction preparation phase, the location of the Y-shaped column 18 was determined, and two support component arrangement areas 21 were designated. These two support component arrangement areas 21 are symmetrically positioned on both sides of the Y-shaped column, with the doorway area 19 of the Y-shaped column as the center of symmetry. According to the design requirements, several sets of vertically installed transfer beam support posts 15 are installed, with the end of each set of support posts connected to the first transverse transfer beam 14. The first transverse transfer beam 14 is then connected to the longitudinal transfer beam 13 to form an overall frame structure. To ensure that the support posts 15 do not contact the Y-shaped column 18, a pre-defined obstacle avoidance area is maintained between each set of posts. This effectively prevents the support posts from interfering with the Y-shaped column and avoids unnecessary impact on the column structure.

[0082] Next, within the two support component arrangement areas 21, several vertically erected auxiliary beam support posts 6 are installed. Each set of auxiliary beam support posts is connected by a first auxiliary beam support crossbar 5 and a second auxiliary beam support crossbar 7, forming a stable auxiliary support system. These support posts are arranged in the gaps between adjacent second transverse transition beams 12 and longitudinal transition beams 13 to ensure the independence and stability of the support system and avoid interference between any components.

[0083] During the erection of the beam formwork, the beam formwork base support 9 is first connected to the beam panel support uprights 11 via the beam panel support crossbars 10, ensuring the stability of the formwork in both vertical and horizontal directions. Similarly, the load-bearing main beam base support 8 is connected to the main beam 2 via the second transverse transfer beam 12, and the auxiliary beam base support 4 is connected to the auxiliary beam 3 via the second auxiliary beam support crossbars 7. This process ensures the stable support of all beam formwork, load-bearing main beams, and auxiliary beams, providing a strong guarantee for concrete pouring.

[0084] After the beam formwork is erected, the rebar tying work begins. The rebar is arranged according to the design drawings to ensure a reasonable distribution of the rebar within the beam and to coordinate with the beam formwork and support system to prevent any accidental displacement or deformation. After the rebar tying is completed, the concrete pouring stage begins. The concrete is poured evenly within the formwork to ensure the strength and stability of the beam structure. After pouring, curing is carried out to maintain suitable temperature and humidity conditions to ensure the quality of the concrete.

[0085] Finally, a comprehensive quality inspection is conducted after construction is completed, focusing on the stability of the support system and beam formwork. This ensures that all supporting structures are robust and reliable, guaranteeing that every step of the construction process meets quality standards. Through this series of precise and scientific construction methods, the stability, construction efficiency, and safety of the entire beam formwork support system are guaranteed.

[0086] This support method offers significant advantages. Through an independently configured support pole system, each set of support poles 15, auxiliary beam support poles 6, and beam panel support poles 11 operates independently without interference, maintaining appropriate spacing from the transfer beam and Y-shaped column. This avoids problems such as support pole interference and unstable formwork found in traditional support methods, greatly improving construction efficiency. Furthermore, this method is highly flexible, suitable for supporting beams of various complex shapes and large spans, and can be adjusted according to actual needs.

[0087] This support method is particularly suitable for the construction of complex structures such as high-rise buildings, long-span bridges, and large factories. It reduces construction time and labor costs, improves construction safety, and effectively reduces safety hazards caused by instability in the support system. Therefore, this support method is not only technically feasible but also demonstrates strong market prospects and promotional value in practical applications.

[0088] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
