Description

Technical Field

[0001] The invention relates to the technical field of energy-saving building material production, and in particular to a prefabricated template component device and a construction method for energy-saving retaining wall construction. Background Art

[0002] As an energy-saving building material, the energy-saving effect of energy-saving prefabricated retaining walls is mainly reflected in many aspects of the entire life cycle of production, construction and use. First, in the production stage, energy-saving prefabricated retaining walls adopt factory manufacturing methods, which can reduce the waste of raw materials and improve material utilization compared with traditional on-site casting methods, while optimizing energy consumption and reducing carbon emissions. Secondly, during the construction process, energy-saving prefabricated retaining walls reduce wet operations through modular assembly, which not only shortens the construction period and reduces the energy consumption of construction equipment, but also reduces noise and dust pollution at the construction site and improves the construction environment. Finally, in the use stage, energy-saving prefabricated retaining walls usually use high-performance materials with good thermal insulation and heat preservation properties, which can effectively reduce the energy consumption demand of buildings and improve indoor thermal comfort. In addition, some energy-saving prefabricated retaining wall materials also have strong durability and recyclability, which further reduces the energy consumption of later maintenance and the generation of construction waste, thereby achieving a more sustainable energy-saving effect.

[0003] At present, the existing pile-slab retaining wall utilizes bored and cast-in-place reinforced concrete piles to constrain the inner reinforced concrete panel and wrap the inner fill to form a retaining wall. The bored and cast-in-place pile construction process is complicated, and the subsequent panel construction can only be carried out after the cast-in-place reinforced concrete column reaches the strength requirement. The construction period is long and it is necessary to set up formwork to complete the pouring of concrete piles above the ground.

[0004] Retaining wall is a kind of structure widely used in civil engineering. It is a kind of building structure that prevents the deformation and instability of fill or soil and bears the lateral earth pressure. Reinforced earth retaining wall is generally composed of foundation, panel, reinforcement material, filler and other main parts. It is a geotechnical structure composed of filler, tie rod and wall panel. There are interactions between the pressure on the back of the wall, the tension of the tie rod and the friction between the filler and the tie rod in this structure, and they reach a mutual balance, which ensures the engineering performance of the geotechnical structure.

[0005] During the manufacturing process of the energy-saving prefabricated retaining wall, in order to improve the quality of the finished retaining wall, the concrete needs to be vibrated continuously to discharge the bubbles in the concrete.

[0016] In a second aspect, the present invention discloses a construction method of an energy-saving prefabricated retaining wall, using a prefabricated template assembly device for energy-saving retaining wall construction as described in any one of the above items, comprising: S1. A movable bracket is arranged on the side of the inclined prefabricated template, and the lifting seat is arranged at the bottom end of the prefabricated template; S2, adjusting the position of the adjustment frame relative to the abutment seat, using a limit socket to fix the adjustment frame and the abutment seat during the search, so that the abutment plate abuts against the surface of the prefabricated template; S3. During the pouring of concrete, the vibration motor is started to control the lifting motor to drive the lifting seat to rise along the lifting rack, and the lifting motor drives the abutment seat to move toward the direction close to the precast template, and the abutment plate is pressed against the surface of the precast template.

[0017] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: 1. The present invention provides a lifting seat on the mobile frame so that the overall structure has adjustable characteristics to meet different construction needs. A lifting motor is installed inside the lifting seat, and the lifting motor drives the lifting seat to perform precise lifting and adjustment in the vertical direction through the lifting gear, so that the entire system can flexibly adjust the height according to the specific conditions of the construction site to ensure that the abutment seat is in a suitable working position. At the same time, the lifting motor is not only limited to height adjustment, but also drives the abutment seat to automatically move toward the prefabricated template in the horizontal direction through the first driving gear, thereby ensuring that the abutment portion can always maintain a close fit with the prefabricated template. Regardless of whether there is a slight position deviation during the manufacturing process, it can be compensated by the automatic adjustment mechanism, avoiding the problem of looseness or position displacement of the abutment portion.

[0018] Through the above-mentioned automatic adjustment design, there is no need for construction personnel to frequently manually adjust the position of the abutment part, which greatly reduces the complexity of manual operation, improves the convenience of construction, and reduces the problem of reduced construction accuracy due to human errors. In addition, the automatic adjustment function of the structure ensures the continuity of the manufacturing process, so that the construction work can be carried out more efficiently, avoiding the time loss caused by frequent shutdowns and adjustments, thereby greatly improving the overall construction efficiency of the energy-saving prefabricated retaining wall during the molding process. At the same time, the design also reduces the labor intensity of construction personnel, making the operation easier and safer, helping to improve construction quality and project stability, and providing construction personnel with a more efficient and intelligent construction assistance solution. In summary, the present invention can not only reduce direct energy consumption during the construction process, but also optimize energy utilization throughout the life cycle of the building, achieving more efficient energy-saving effects.

[0019] 2. The present invention arranges a first strong spring between the first driving gear and the output shaft of the lifting motor, so that when the lifting motor drives the first driving gear to rotate, the first strong spring can play a buffering and absorbing role, thereby effectively reducing the driving force directly transmitted to the first driving gear. The elastic force of the first strong spring can provide a certain flexible adjustment space during the contact between the abutment plate and the prefabricated template, avoiding excessive thrust caused by rigid transmission, so that the abutment plate can maintain close contact with the prefabricated template while still having a certain sliding margin.

[0020] The setting of this structure can not only prevent the abutment plate from being pressed against the prefabricated formwork due to excessive force, resulting in the problem of sliding obstruction, but also provide a certain buffer protection during the construction process, reducing the damage to the abutment plate or the prefabricated formwork caused by excessive pressure. Especially during the manufacturing process, since there may be local unevenness or slight errors on the surface of the wallboard, the elastic adjustment function of the first strong spring can adapt to these slight deformations or deviations, so that the abutment plate can always maintain a stable fit and slide smoothly along the prefabricated formwork, ensuring the continuity and accuracy of the construction process.

[0021] In addition, the elastic adjustment mechanism can effectively reduce the impact of sudden force changes on the lifting motor during the driving process, extend the service life of the motor and transmission mechanism, and improve the durability and reliability of the entire device. Compared with the traditional rigid connection drive method, this design improves construction efficiency while also enhancing the safety and controllability of the construction process, so that the entire system can maintain a good operating state in different construction environments, providing more stable and efficient support for construction operations; 3. The present invention sets a sliding connection between the adjustment frame and the abutment seat, so that the adjustment frame can be flexibly adjusted along the guide track of the abutment seat, thereby accurately controlling the position of the adjustment frame according to the actual distance between the abutment plate and the prefabricated template. The sliding connection structure makes the adjustment frame adjustable. During the initial installation or construction process, the construction personnel can move the adjustment frame appropriately according to the specific size and position of the prefabricated template, so that the abutment plate and the prefabricated template are closely fitted, thereby ensuring the stability and accuracy of the construction.

[0022] In actual application, the sliding adjustment of the adjustment frame can not only adapt to prefabricated templates of different thicknesses or specifications, but also make fine adjustments during the construction process to cope with dimensional deviations caused by material tolerances, installation errors or environmental factors. Through the sliding adjustment function of the adjustment frame, even if there are local unevenness on the surface of the prefabricated template, it can ensure that the abutment plate always maintains a uniform fit with the prefabricated template, avoiding the problem of force concentration or sliding obstruction caused by uneven contact, and improving the stability and safety of construction.

[0023] In addition, the sliding connection design can also optimize the convenience of construction operations, reduce the tedious operations of construction personnel when adjusting the position of the abutment plate, avoid frequent disassembly or repositioning, and improve the construction efficiency during the manufacturing process. At the same time, the structure can also be combined with an automatic adjustment mechanism to ensure that the adjustment frame always maintains a suitable adjustment range on the abutment seat, ensuring that the abutment plate can stably and reliably fit the prefabricated template during the manufacturing process and slide smoothly when needed, further enhancing the adaptability and durability of the entire device, so that it can adapt to different construction environments and engineering needs.
