Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.
[0017] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the product of the utility model is usually placed when in use. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.
[0018] Furthermore, the use of terms such as "horizontal," "vertical," and "overhanging" does not necessarily imply that the component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted.
[0019] In the description of the embodiments of the present invention, “a plurality of” means at least 2.
[0020] In the description of the embodiments of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0021] The invention discloses a screw-free formwork reinforcement device for an ultra-thick corner wall, which is arranged on the outside of an aluminum formwork and includes two groups of back ribs arranged at a concave corner or a convex corner. The back ribs include two symmetrically arranged ribs with a connector provided between the two ribs.
[0022] At the external corner, the rib is an I-steel 1, and the connecting piece is a connecting square steel 3. Two I-steels 1 are welded to the connecting square steel 3. Three angle steels with holes 2 are welded on the outside of the two I-steels 1. A screw 4 with a diameter of not less than 28 mm passes through the angle steels with holes 2 between the two groups of back ribs and is connected and fixed by a tension nut 5. A gasket 6 is provided between the tension nut 5 and the angle steels with holes 2.
[0023] At the inner corner, the ribs are back rib square steel 7, and the connecting parts are connecting steel plates 8; two groups of back ribs are made into right-angle shapes to form right-angle back ribs, and the aluminum mold is fixed by the right-angle back ribs; the right-angle back ribs and ordinary back ribs are connected by through-wall bolts at the wall of the non-corner part.
[0024] This new design features reinforced back ribs made of I-beams and square steel, along with perforated angle iron welded to the back ribs. By designing screws on the outer sides of the reinforced back ribs and corners, screw-free reinforcement is achieved, improving the assembly efficiency and construction quality of the aluminum alloy formwork. The back ribs at the internal corners are welded together by two steel plates to create a right-angled shape, securing the aluminum alloy formwork.
[0025] External Corner Reinforcement: At the external corners of the core tube wall, two I-beams and square steel are welded together, with three perforated angles welded to one end to form a reinforced back rib. The aluminum alloy formwork is secured with this reinforced back rib. One end of this reinforced back rib extends outward for a certain distance, and a thickened screw passes through the perforated angles welded to the back rib, connecting the two aluminum formworks into a single piece.
[0026] Internal corner reinforcement: At the internal corners of the core tube wall, two square steel bars are welded together through steel plates to form a right-angled back rib, which secures the aluminum alloy formwork. This back rib is connected to the standard back rib via through-wall screws in the non-corner areas of the wall, ensuring the integrity of the aluminum film while facilitating assembly and disassembly of the aluminum formwork.
[0027] The utility model realizes screw-free reinforcement of ultra-thick corner positions by strengthening the back ribs and the back rib connection method.
[0028] During the specific implementation of the present invention, the preparation stage is as follows: the required materials are prepared according to the construction drawings, including an electric drill, a torque wrench, a hammer, an air compressor, a bench drill, a portable electric saw, a portable electric planer, an electric welder, wire cutters, an ink fountain, chalk line tape, tension screws, tension nuts, etc.
[0029] Assemble the formwork: Assemble the aluminum formwork piece by piece according to the construction sequence. Use thickened screws through the perforated angle iron to connect the two aluminum formwork pieces. Ensure that all contact surfaces and edges of the formwork are cleaned and oiled.
[0030] Installation of back ribs: The reinforced back ribs of internal and external corners are processed into finished products by the manufacturer and then sent to the site. They can be directly assembled during the construction process. After the aluminum alloy template is assembled, it can be used at the external corner position. Figure 1 The I-beam reinforced back ribs are connected by thickened screws, bolts and washers; the inner corner position is used Figure 2 The right-angle back rib shown is fixed and connected to the ordinary back rib via wall-penetrating screws.
[0031] Concrete pouring: After the formwork is installed, concrete pouring is carried out. During the pouring process, pay attention to controlling the concrete quality and pouring speed to avoid bubbles and voids.
[0032] Curing and demolding: After the concrete is poured, it is cured and demolded after the concrete reaches the specified strength. During the demolding process, pay attention to protecting the concrete surface to avoid damage.
[0033] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without creatively designing a structure and embodiment similar to the technical solution, they shall fall within the scope of protection of the present invention.
