Description

Technical Field

[0001] The invention relates to an aluminum formwork for concrete pouring, and in particular to an assembled self-adaptive aluminum formwork on an uneven ground and a concrete pouring method. Background Art

[0002] When pouring concrete on uneven surfaces or structures, formwork installation is a key challenge. Examples include the top of the arch back of a hyperbolic arch bridge with bidirectional longitudinal and transverse curvature, cast-in-place shoulder leveling layers on the operating side of sections with varying terrain and elevation, and slopes with significant gradient changes. Formwork construction typically utilizes wooden or steel formwork. While wooden formwork is inexpensive, easy to assemble, and can be cut to appropriate dimensions based on varying ground elevations, it is cumbersome to assemble and has poor environmental adaptability. It easily deforms in contact with water and high temperatures, affecting the quality of the concrete. After demolding, the formwork is difficult to reuse, resulting in low reuse value, material waste, and environmental pollution. Steel formwork produces high-quality concrete, is easily reusable, and is easy to demold. However, its heavy weight and relatively fixed dimensions make it less flexible and poorly adaptable to terrain with significant elevation changes or environments with weak foundation bearing capacity.

[0003] Therefore, to address the problems of cumbersome formwork support and the inability of the formwork to adapt well to terrain and height changes in concrete pouring construction on uneven ground or structures, a new formwork structure and construction method are proposed. Summary of the Invention

[0018] Preferably, the method for pouring concrete using an assembled adaptive aluminum formwork on an uneven ground comprises the following steps:

[0019] S1. Design and production of aluminum formwork: The aluminum formwork is produced. A connecting top plate is set on the top of the aluminum formwork, and connecting side plates are set on the left and right sides. Connecting bolt holes are drilled at intervals in the connecting top plate, and aluminum formwork connecting holes are drilled at intervals in the connecting side plates; and a limiting plate of the same width as the aluminum formwork is installed at the bottom of the aluminum formwork through connecting screws.

[0020] S2.

Weld transverse stiffening plates at intervals from top to bottom on the vertical plate side of the T-shaped slide rail.

[0021] S3. Design and production of adaptive grooved sliders: Make a grooved slider with the same length as the T-shaped slide rail, install a conversion head and an elastic head at the end of the grooved slider, and adjust the elastic body to the top using the fine-tuning knob.

[0022] S4. Assembly of prefabricated adaptive aluminum formwork:

[0023] S4.1. Install the slide rail connecting plate to the aluminum formwork connecting top plate using connecting bolts.

[0024] S4.2. Install the grooved slides onto the T-shaped slide rails one by one. Fill the gaps between the T-shaped slide rails and the grooved slides with lubricant. The waterstop strips of adjacent grooved slides fit into the waterstop grooves.

[0025] S4.3. After the internal grooved slides of the aluminum formwork are installed, they are adjusted to the position where they completely overlap with the T-shaped slide rails. A limiting plate is installed at the bottom of the aluminum formwork and the formwork is transported to the construction site.

[0026] S5. Assembly and support of self-adaptive aluminum formwork:

[0027] S5.1. Set up the first piece of prefabricated self-adaptive aluminum formwork, and initially adjust the grooved slides to fit the uneven ground surface, and then fix the grooved slides on the T-shaped slide rails.

[0028] S5.2. Install two rows of U-shaped slotted pallets on the horizontal stiffening plate on the back of the aluminum formwork, and install bottom fixed pallets on the ground outside the aluminum formwork. The same bottom fixed pallet is connected to the two slotted pallets in the same plane through two diagonal braces.

[0029] S5.3. Make a filler slide with a length equal to the height difference between the adjacent aluminum formwork and the ground. After the first aluminum formwork is installed and fixed, install the filler slide so that the trough slide that slides downward is completely in contact with the ground. Continue to splice the aluminum formwork on the other side of the filler slide and adjust the height difference of the trough slide.

[0030] S5.4. Assemble the aluminum formwork piece by piece in sequence and install the filling slides until the formwork support requirements are met.

[0031] S5.5. Adjust the position of the elastic body inside the conversion head by turning the knob cap so that the elastic body fits the ground and resists the lateral pressure generated during concrete pouring.

[0032] S6. Concrete pouring: After the aluminum formwork is erected on the uneven ground, concrete is poured inside the formwork and maintained.

First, remove the adjustable diagonal brace, and then remove the trough-shaped slide bar and integral slide rail from the aluminum formwork.

[0034] The technical solution of the present invention has the following beneficial effects compared with the traditional technology:

[0035] 1. The assembled adaptive aluminum formwork is made of aluminum alloy material as a whole. Compared with the steel formwork, its own weight is lower and the construction efficiency is high. The concrete surface after forming is flat and smooth. The formwork has a long service life and can be used multiple times.

[0036] 2. The side of the template consists of a top aluminum template and a bottom adaptive groove slide, and an elastic body is set at the bottom of the adaptive slide; according to the height difference of the ground, the groove slide is initially adjusted, and the elastic body is fine-tuned to make the template completely fit the uneven ground, with strong environmental adaptability.

[0037] 3. The assembled adaptive aluminum formwork consists of a standard aluminum formwork, matching adaptive grooved slides and T-shaped slide rails. The T-shaped slide rails are fixed to the connecting plate and installed on the top of the aluminum formwork through fixing bolts. The formwork support can be completed by installing adjustable diagonal braces on the back of the formwork. The formwork installation process is efficient, and splicing and adjustment are convenient, which significantly improves construction efficiency and saves labor costs.

[0038] 4. The side ends of the adaptive groove slides are equipped with water stop strips and water stop grooves. The adjacent groove slides can be installed by embedding the water stop strips into the water stop grooves, which is convenient for assembly. The connecting plate on the back of the T-shaped slide rail can ensure the structural reliability of the adjacent groove slides, and the construction safety is high.
