Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of building construction, and more specifically, particularly relates to a variable bracket of an inner box of an inclined high pier. Background Art
[0002] The variable bracket of the inner box of the inclined high pier is a support device used in large-scale construction projects for the construction of the inner box structure of the pier with an inclined angle and high. It plays an important role in scenes such as bridge engineering and the core tube construction of high-rise buildings. In practical applications, this variable bracket usually requires the use of the following structures and technologies:
[0003] 1. Welded trusses: welded from I-beams and other steel materials, they are the main load-bearing skeleton of the bracket, bearing the load from the upper structure and transferring it to the foundation and other supporting structures.
[0004] 2. Channel steel parallel connection: It is connected to the welded trusses by welding or bolting, etc., to connect each truss into a whole, enhance the stability of the bracket in the horizontal direction, enable the bracket to bear force synergistically, and jointly resist lateral force and uneven load.
[0005] 3. Stiffening plate: It is connected to welded trusses, distribution beams and other components by welding, and is used to strengthen the local stability of the main load-bearing components and prevent local buckling and deformation of the components during the stress process.
[0006] At present, in large-scale construction projects, manufacturers have adopted a variety of support forms and construction methods for the construction support of the inner box of the oblique high pier. Some manufacturers use fixed supports, which have a simple structure but lack flexibility and are difficult to adapt to the construction of inner boxes of piers of different sizes and inclination angles. During the construction process, once there is a slight change in the size or angle of the inner box, the support needs to be modified or even remade, resulting in increased construction costs and delays in the construction period. Some manufacturers use traditional scaffolding support methods, which have certain buildability but poor stability, especially in high piers and oblique structures, which are prone to safety hazards such as scaffolding deformation and collapse. In addition, the construction and dismantling of scaffolding are cumbersome, requiring a lot of manpower and time, and the construction efficiency is low.
[0007] However, the above implementation still has the following problems: in terms of the adaptability of the bracket, the fixed bracket cannot be flexibly adjusted according to the actual situation of the inner box, which makes it difficult to ensure the construction quality and progress when facing a complex and changeable construction environment. In terms of construction safety, the traditional scaffolding support method cannot withstand the various loads in the construction of the inner box of the inclined high pier due to its own structural limitations, and there is a great safety risk. In terms of construction efficiency, whether it is the difficulty in modifying the fixed bracket or the cumbersome construction and dismantling of the scaffolding, it seriously affects the overall efficiency of the construction and increases the project cost. In response to this problem, this application proposes a solution to design a variable bracket for the inner box of the inclined high pier. The bracket has good adaptability and can be flexibly adjusted according to the size, angle and other parameters of the inner box to ensure the construction quality; by optimizing the structural design and connection method, the stability and safety of the bracket are improved, and the construction risk is effectively reduced; at the same time, its convenient installation, disassembly and adjustment method greatly improves the construction efficiency and reduces the project cost, providing a more efficient, safe and reliable support method for the construction of the inner box of the inclined high pier.

[0026] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0027] See also Figure 1 - Figure 6The present invention provides a variable bracket for the inner box of an oblique high pier, comprising a group of I-beams 1, a group of I-beams 2 12 and a group of I-beams 3 13, each of the upper surfaces of the I-beams 2 12 is fixedly connected with a connecting steel 11 and two fixing steels 10, a group of I-beams 1 and a group of connecting steels 11 are fixedly connected with connecting steels 2 14, a group of I-beams 1 and a group of connecting steels 11 are fixedly connected with two welded trusses 8 on their upper surfaces, each of the I-beams 2 12 is provided with a group of stiffening plates 5, a group of I-beams 2 12 is fixedly connected with a group of I-beams 3 13, a group of I-beams 1 are provided with channel steel flat joints 2 on their right surfaces, a group of I-beams 2 12 is fixedly connected with a group of I-beams 1 1, firstly, a bracket erection operation is performed to construct a basic support structure for subsequent construction, and a platform 16, a platform 2 18, a platform 3 19 and a channel steel flat joint 2 are installed, and the channel steel flat joint 2 is operated. The purpose is to enhance the overall stability of the bracket and ensure the coordinated force between the various parts. After the installation is completed, an inspection is carried out to ensure that the channel steel flat joint 2 is installed properly and meets the design requirements and safety standards. When the concrete reaches 75% of the design strength, use a jack or winch to move the frame back 10 cm to fix the steel. The purpose of this step is to make room for the subsequent installation of the I-beam load-bearing frame, and at the same time adjust the position of the bracket to better meet the construction needs. During the construction process, taking into account factors such as concrete shrinkage and the deformation of the bracket itself, by reserving a certain amount of backward space and setting wedge blocks 3, the bracket system can adapt to structural deformation within a certain range, avoiding cracks or damage due to excessive constraints on deformation. At the same time, as the size of the inner box gradually changes, by adjusting the position of the connecting plate set on the channel steel flat joint 2, it is ensured that the bracket is always closely fitted with the inner box, maintaining a stable support state, and ensuring construction safety and quality.
[0028] A group of I-beams 12 and a group of connecting steels 14 are provided with wire meshes 9 on their upper surfaces, a group of I-beams 12 are fixedly connected with wedge blocks 3 on their right surfaces, a group of I-beams 12 are fixed with steel bars 6 by welding at the bottom, an I-beam load-bearing frame is installed, the I-beam load-bearing frame is composed of a group of I-beams 1, a group of I-beams 12 and a group of stiffening plates 5, the frame is adjusted to ensure that it is in a suitable position and state, and is prepared to bear subsequent construction loads, and a stable spatial structure is formed by reasonably selecting and arranging various steel components. The structure system is interconnected and jointly bears various vertical and lateral forces from the deadweight of concrete, construction load, etc. The frame is pushed up and close to the formwork slices 15 to ensure that the formwork slices 15 are stably supported during the construction process and prevent the formwork slices 15 from displacement or deformation, thereby ensuring the quality of concrete casting. Wedge blocks 3 are installed at the rear edge and reinforced to further enhance the connection stability between the formwork slices 15 and the support system and prevent the formwork slices 15 from loosening or expanding during the concrete pouring process.
[0029] The right ends of a group of I-beams 12 are fixedly connected with supporting steels 4, the inclined sides of a group of connecting steels 11 are provided with a group of distribution beams 7, and the left sides of a group of connecting steels 11 are provided with formwork segments 15. The construction of a segment, including steel bar binding, concrete pouring and other work, must be carried out in strict accordance with relevant specifications and design requirements during the construction process to ensure the construction quality. After the construction is completed, an inspection is carried out, including the quality of concrete pouring, the stability of the support system, the integrity of the formwork and other aspects. After the inspection is qualified, concrete pouring is carried out, and the above operations are repeated until the construction of the capped solid section is completed. During the construction process, as the construction height increases, the support system needs to constantly adapt to the gradual change in the size of the inner box. For every 2 modules (8m) of climbing, the connecting plate set on the channel steel flat joint 2 needs to be moved inward by 27cm, and for every 1 module (4m) of climbing, it also needs to be moved inward by 27cm. Through such adjustments, it is ensured that the support is always in close fit with the inner box to provide reliable support for the construction. The coordinated work of components such as the channel steel flat joint 2 and the distribution beam 7 is utilized to evenly distribute the load to the entire support system to avoid local stress concentration. The channel steel flat joint 2 connects the various welded trusses 8 together, thereby enhancing the integrity of the support and enabling it to better resist lateral forces.
[0030] A platform 16 and a ladder 17 are arranged on the upper surface of a group of I-beams 12, a platform 2 18 is arranged above the I-beam 12, and the platform 2 18 is fixedly connected to the ladder 17. A platform 3 19 is arranged above the connecting steel 2 14, and the platform 3 19 and the platform 1 16 are respectively composed of two steel meshes 9. The distribution beam 7 reasonably distributes the upper load to the load-bearing beam to ensure that each load-bearing beam is evenly stressed, thereby improving the bearing capacity of the entire support system. The precise support design and construction process can effectively ensure the geometric shape and dimensional accuracy of the inner box, so that the inner box structure after concrete pouring meets the design requirements, and reduces the quality problems such as uneven concrete surface and uneven thickness caused by support deformation or instability. The support system has strong stability and adaptability, and can better control the position and deformation of the template during construction, ensuring that the concrete is well restrained and supported during pouring and hardening, thereby improving the density and strength of the concrete and ensuring the overall quality of the inner box structure. Reasonable structural design and material selection enable the support system to have sufficient bearing capacity and stability and be able to withstand construction Various loads in the process can effectively prevent the occurrence of safety accidents such as support collapse. During the construction process, by setting up auxiliary facilities such as ladders 17 and platform guardrails, safe working channels and protective measures are provided for construction personnel, reducing the risks of construction personnel falling from heights, and ensuring the personal safety of construction personnel. The adjustability and modular design of the support system make it more convenient and quick during installation, disassembly and adjustment. For example, the overall backward movement of the frame and the adjustment of the position of the connecting plate are relatively simple, and can be adjusted in time according to the construction progress and changes in the size of the inner box, reducing downtime and repeated operations during construction, and improving construction efficiency. The support system has high reusability and can be used multiple times in different construction stages or similar projects, reducing the cost of engineering materials. By reasonably designing the support structure and optimizing the use of materials, unnecessary material consumption and construction processes are reduced while ensuring construction safety and quality, thereby reducing the overall cost of the project and improving economic benefits. At the same time, improving construction efficiency also indirectly reduces construction costs, making the project more economically reasonable and feasible.
[0031] Working principle:
[0032] The first step is to set up a support structure to build a basic support structure for subsequent construction. Platform 1 16, platform 2 18, platform 3 19 and channel steel flat joint 2 are installed. The function of channel steel flat joint 2 is to enhance the overall stability of the support and ensure the coordinated force between the various parts. After the installation is completed, an inspection is carried out to ensure that the channel steel flat joint 2 is installed properly and meets the design requirements and safety standards. When the concrete reaches 75% of the design strength, the frame is moved back 10 cm by a jack or a winch. The purpose of this step is to make room for the subsequent installation of the I-beam load-bearing frame and adjust the position of the support to better meet the construction needs. During the construction process, considering factors such as concrete shrinkage and deformation of the support itself, a certain amount of backward space is reserved and wedge blocks 3 are set, so that the support system can adapt to structural deformation within a certain range, avoiding cracks or damage due to excessive constraints on deformation. At the same time, as the size of the inner box gradually changes, the position of the connecting plate set on the channel steel flat joint 2 is adjusted to ensure that the support is always closely fitted with the inner box, maintaining a stable support state, and ensuring construction safety and quality.
[0033] The second step is to install the I-beam load-bearing frame. The I-beam load-bearing frame consists of a group of I-beams 1, a group of I-beams 2 12 and a group of stiffening plates 5. The frame is adjusted to ensure that it is in a suitable position and state to prepare for the subsequent construction load. A stable spatial structural system is formed by reasonably selecting and arranging various steel components. These components are interconnected to jointly bear various vertical and lateral forces such as the dead weight of concrete and construction loads. The frame is pushed against the template slice 15 to ensure that the template slice 15 is stably supported during the construction process and prevent the template slice 15 from displacement or deformation, thereby ensuring the quality of concrete casting. Wedge blocks 3 are installed at the rear edge and reinforced to further enhance the connection stability between the template slice 15 and the bracket system and prevent the template slice 15 from loosening or expanding during the concrete pouring process. A stage of construction is carried out, including steel bar binding, concrete pouring and other work. During the construction process During the construction process, operations must be carried out strictly in accordance with relevant specifications and design requirements to ensure the quality of construction. After the construction is completed, an inspection will be carried out, including the quality of concrete pouring, the stability of the support system, the integrity of the formwork, etc. After the inspection is qualified, concrete pouring will be carried out, and the above operations will be repeated until the construction of the solid section with capping is completed. During the entire construction process, as the construction height increases, the support system needs to continuously adapt to the gradual change of the inner box size. For every 2 molds (8m) of climbing, the connecting plate set on the channel steel flat joint 2 needs to be moved inward by 27cm, and for every 1 mold (4m) of climbing, it also needs to be moved inward by 27cm. Through such adjustments, it is ensured that the support is always closely fitted with the inner box to provide reliable support for the construction. The coordinated work of components such as the channel steel flat joint 2 and the distribution beam 7 is used to evenly distribute the load to the entire support system to avoid local stress concentration. The channel steel flat joint 2 connects each welded truss 8 together, which enhances the integrity of the support and enables it to better resist lateral forces.
[0034] In the third step, the distribution beam 7 distributes the upper load to the load-bearing beam reasonably to ensure that each load-bearing beam is evenly stressed, thereby improving the bearing capacity of the entire support system. Accurate support design and construction process can effectively ensure the geometric shape and dimensional accuracy of the inner box, so that the inner box structure after concrete pouring meets the design requirements and reduces quality problems such as uneven concrete surface and uneven thickness caused by support deformation or instability. The support system has strong stability and adaptability, and can better control the position and deformation of the template during construction to ensure that the concrete is well restrained and supported during pouring and hardening, thereby improving the density and strength of the concrete and ensuring the overall quality of the inner box structure. Reasonable structural design and material selection enable the support system to have sufficient bearing capacity and stability, be able to withstand various loads during construction, and effectively prevent the occurrence of safety accidents such as support collapse. During the construction process, by setting ladders 17 and platform guardrails The auxiliary facilities such as the bracket system provide safe working channels and protective measures for construction workers, reduce the risks of falling from heights, and ensure the personal safety of construction workers. The adjustability and modular design of the bracket system make it more convenient and quick during installation, disassembly and adjustment. For example, the overall backward movement of the frame and the adjustment of the position of the connecting plate are relatively simple, and can be adjusted in time according to the construction progress and changes in the size of the inner box, reducing downtime and repeated operations during construction and improving construction efficiency. The bracket system is highly reusable and can be used multiple times in different construction stages or similar projects, reducing the cost of engineering materials. By reasonably designing the bracket structure and optimizing the use of materials, unnecessary material consumption and construction processes are reduced while ensuring construction safety and quality, thereby reducing the overall cost of the project and improving economic benefits. At the same time, improving construction efficiency also indirectly reduces construction costs, making the project more economically reasonable and feasible.
