Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a large-volume and ultra-thick concrete pouring structure. Background Art

[0002] Large-volume, ultra-thick concrete refers to a concrete structure with a large, deep thickness poured in a single pour. It is typically used in projects with high load-bearing capacity requirements, such as the foundations of high-rise buildings. Due to the large volume of concrete, a significant amount of hydration heat is generated during the pouring process, which can easily cause temperature cracks. Therefore, special construction techniques are required to control temperature, cracks, and deformation. To ensure the stability and quality of large-volume, ultra-thick concrete structures, high-strength formwork structures must be used. These formworks utilize special mechanical mechanisms such as steel supports, prestressed tie rods, and hydraulic supports to provide high stability and support. They can effectively withstand the enormous loads and lateral pressure generated during concrete pouring, ensuring construction safety and structural integrity.

[0003] Traditional large-volume, ultra-thick concrete pouring structures typically utilize materials such as steel or wooden formwork to support and shape the concrete. During construction, the formwork system utilizes supporting structures such as steel pipe supports, scaffolding, or diagonal braces to resist the concrete's deadweight and lateral pressure, ensuring the formwork's stability and resistance to deformation. To prevent leakage and ensure the quality of the concrete, the joints between the formwork are sealed, and concrete vibration and temperature fluctuations are strictly controlled during the pouring process. Furthermore, the formwork is gradually removed after the concrete has initially set to ensure a smooth, crack-free surface after the finished structure is formed, maintaining its integrity and precision.

[0004] In traditional large-volume, ultra-thick concrete pouring structures, the formwork is usually spliced together by multiple formwork units, with many joints. It is easy for loose joints to leak concrete during pouring or vibration, resulting in quality defects such as uneven concrete surface, insufficient strength, and honeycombed surface.

[0029] Working principle: When a large-volume and ultra-thick concrete pouring structure is required, first install the horizontal pouring formwork 2 and the vertical pouring formwork 3 in the preset embedded points inside the foundation 1. In this process, the positioning blocks 5 preset in the outer walls of the horizontal pouring formwork 2 and the vertical pouring formwork 3 are inserted into each other's interior to achieve preliminary positioning. At the same time, the sealing gasket 6 on the outer wall of the positioning block 5 is used to achieve preliminary sealing. At this time, a sealing groove 9 is formed at the connection between the horizontal pouring formwork 2 and the vertical pouring formwork 3. Then, the elastic sealing gasket 13 is inserted into the inside of the sealing groove 9, so that the right-angle connecting plate 7 fits the outer wall of the horizontal pouring formwork 2 and the vertical pouring formwork 3.

Then, the driver 11 moves inside the right-angle connecting plate 7, and cooperates with the T-shaped slider 12 to drive the trapezoidal push plate 10 to slide inside the right-angle connecting plate 7 and the elastic sealing gasket 13. Since the volume of the trapezoidal push plate 10 is slightly larger than the preset slide groove inside the elastic sealing gasket 13, the elastic sealing gasket 13 is deformed as the trapezoidal push plate 10 moves, thereby making the elastic sealing gasket 13 tightly fit inside the horizontal injection template 2 and the vertical injection template 3, thereby achieving stable sealing during pouring concrete 4 and vibrating.

At this time, the other side of the outer wall of the angle steel bracket 14 is in contact with the foundation 1, and then the screw 18 is driven to drive the fixed end 19 and the barb 20 to move to the inside of the foundation 1, thereby fixing the angle steel bracket 14, and then achieving support and fixation of the horizontal casting formwork 2 and the vertical casting formwork 3.
