Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, in particular to a reusable aluminum template for concrete pouring. Background Art

[0002] Aluminum alloy formwork, full name is concrete engineering aluminum alloy formwork, aluminum alloy formwork is mainly made of aluminum alloy profiles, and is suitable for concrete engineering through mechanical processing and welding. It is designed according to the 50mm module and is composed of panels, ribs, main profiles, plane formwork, corner formwork, and early dismantling devices. It has the advantages of high strength, good stability, high precision, short assembly cycle, recyclable, low cost, and high recycling rate. It is a new generation of formwork system after plywood formwork, combined steel formwork system, steel frame wood plywood system, large formwork system, and early dismantling formwork system, but it still has the following disadvantages in actual use:

[0003] 1. The utility model with announcement number CN207829451U discloses a building aluminum alloy formwork combination structure, wherein aluminum formwork 1 and aluminum formwork 3 are straight formworks, and a C-shaped groove for placing bolts is provided on the support surface thereof, and reinforcing ribs are provided inside the aluminum formwork; aluminum formwork 2 and aluminum formwork 4 are corner formworks; aluminum formwork 2 is an oblique combination formwork, and the oblique angles and bevels of two aluminum formworks 2 are butt-jointed and combined to form a group of oblique combination corner formworks; each aluminum formwork is connected and combined by fasteners to form a formwork combination structure, and aluminum formworks usually produce a variety of structures for easy combination and adjustment, and are suitable for arbitrary combination of all parts of buildings such as beams, columns, walls, floor slabs, doors and windows, balconies, shafts and scattered components, but in actual use, construction personnel need to take a variety of different structures for assembly according to the specific needs of the construction, and when the memory is deviated, there may be a shortage of some parts, so before construction, a certain number of each structure needs to be brought for backup, which increases the transportation cost, and the flexibility of the use of aluminum formworks is low;

[0004] 2. When separating the aluminum formwork from the concrete, although the surface of the aluminum formwork is relatively smooth, it is inevitable that the concrete and the aluminum formwork will stick together during separation, making it difficult to disassemble the aluminum formwork. After repeated use, the surface of the aluminum formwork will wear out, which not only further increases the difficulty of disassembly, but also some concrete may fall off after the aluminum formwork is disassembled, increasing the difficulty of construction. Utility Model Content

[0005] The purpose of the utility model is to provide a reusable aluminum formwork for concrete pouring. Through the aluminum formwork main body and the first rotating connecting plate, the problem that when the aluminum formwork is actually used, it is necessary to take aluminum formworks of different structures in excess of the required number according to construction requirements, which increases transportation costs, makes disassembly difficult when the aluminum formwork is separated from the concrete, and the surface of the aluminum formwork is prone to wear after repeated use, further increasing the difficulty of disassembly.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a reusable aluminum formwork for concrete pouring, comprising an aluminum formwork body and a first rotating connecting plate, a one-way valve is arranged on one side of the aluminum formwork body, a partition net is clamped on the other side of the aluminum formwork body, and the first rotating connecting plate and the second rotating connecting plate are respectively rotatably clamped on both ends of the aluminum formwork body, and one of the first rotating connecting plates is clamped on one side of one of the second rotating connecting plates;

[0008] After the concrete solidifies, by inflating the one-way valve, the air pressure between the aluminum formwork body and the concrete can be greater than the external air pressure, and the air pressure can quickly create a gap between the aluminum formwork and the concrete, reducing the difficulty of disassembly. The first rotating connecting plate and the second rotating connecting plate can rotate with the two ends of the aluminum formwork body as the axis, and the angle between the two aluminum formworks can be adjusted, so that the aluminum formwork can adapt to concrete pouring construction at different angles, thereby improving the flexibility of use, eliminating the need to transport structures of multiple shapes, and eliminating the need to spare a large number of aluminum formworks with different structures, thereby reducing the difficulty of transportation.

[0009] Furthermore, mounting connecting plates are welded and fixed at both ends of one side of the aluminum template body, rotating frames are welded and fixed at both ends of both sides of the aluminum template body, and positioning bolts are inserted through one end of each set of rotating frames;

[0010] The first rotating connecting plate and the second rotating connecting plate can rotate with the rotating frame as the axis to adjust the angle between the two aluminum templates, so that the aluminum templates can adapt to concrete pouring construction at different angles, thereby improving the flexibility of use. A slide plate can be set on one side of each rotating frame to prevent concrete from entering the gap between the rotating frame and the first rotating connecting plate, the rotating frame and the second rotating connecting plate.

[0011] Further, a ventilation groove is provided inside the aluminum template body, a reinforcing plate is inserted through one side of the aluminum template body, the one-way valve is inserted through one side of the reinforcing plate, the reinforcing plate is located on one side of the mounting connecting plate of the aluminum template body, the partition net is connected through the ventilation groove, the partition net is located on the other side of the ventilation groove relative to the reinforcing plate, and the one-way valve is connected through the ventilation groove;

[0012] The structure of the aluminum formwork body and the partition net can be strengthened by the reinforcement plate to extend the service life of the aluminum formwork body. When disassembling the aluminum formwork body and concrete, the one-way valve is inflated by an air pump to make the air pressure in the ventilation groove greater than the external air pressure, and further make the air pressure between the aluminum formwork body and the concrete greater than the external air pressure. The air pressure quickly creates a gap between the aluminum formwork and the concrete, which is convenient for the staff to quickly disassemble the aluminum formwork. Compared with disassembly by directly applying force, air pressure is less likely to cause damage to the aluminum formwork and the concrete surface, thereby improving construction efficiency. At the same time, after a certain period of use, the partition net can be disassembled and replaced to reduce construction expenses.

[0013] Further, a first positioning thread groove is formed on one side of one end of the first rotating connecting plate, a connecting block is welded and fixed on one side of the first rotating connecting plate, connecting thread grooves are formed on both ends of the connecting block, the connecting block is located on the other side of the first rotating connecting plate relative to the first positioning thread groove, one side of the first rotating connecting plate is rotatably clamped on the inner side of a group of rotating frames, one of the positioning bolts is screwed and fixed on the inner side of the first positioning thread groove, a first sliding groove is formed on one side of the first rotating connecting plate, and a first slide plate is slidably clamped in the first sliding groove;

[0014] The first rotating connecting plate can rotate with the rotating frame as the axis, so that the angle between the two connected aluminum templates can be adjusted as needed, so that the aluminum template can adapt to concrete pouring construction at different angles, thereby improving the flexibility of use, eliminating the need to transport multiple structures of different shapes, and eliminating the need to spare a large number of aluminum templates with different structures, thereby reducing the difficulty of transportation.

[0015] The cam is an angular channel formed on one side of the second rotation connecting plate, and the cam is abutted against the second end of the second rotation connecting plate to form a circle with a circle around the cam.

[0016] By sliding the first slide plate and the second slide plate, they can fit together with one end of the slide plate of the aluminum formwork body to prevent concrete from entering the gaps between the rotating frame and the first rotating connecting plate, and the rotating frame and the second rotating connecting plate.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model solves the problem that aluminum formworks are usually produced in a variety of structures for easy combination and adjustment by arranging an aluminum formwork main body and a first rotating connecting plate, and is suitable for arbitrary combination of all parts of a building such as beams, columns, walls, floor slabs, doors and windows, balconies, shafts and miscellaneous components. However, in actual use, construction personnel need to assemble a variety of different structures according to specific construction needs. When memory deviation occurs, some parts may be insufficient. Therefore, before construction, a certain number of each structure needs to be brought as spare parts, which increases transportation costs, and the flexibility of the use of the aluminum formwork is low. When transporting the aluminum formwork, only the bolts and the aluminum formwork need to be transported. When installing between two aluminum formworks, the first rotating connecting plate and the second rotating connecting plate are rotated as needed to adjust the angle between the two aluminum formwork main bodies, so that the aluminum formwork can adapt to concrete pouring construction at different angles, thereby improving the flexibility of use, eliminating the need to transport a variety of structures of different shapes, and eliminating the need to spare a large number of aluminum formworks of different structures, thereby reducing the difficulty of transportation.

[0019] 2. The utility model solves the problem that when the aluminum formwork is separated from the concrete, although the surface of the aluminum formwork is relatively smooth, adhesion between the concrete and the aluminum formwork is inevitable during separation, which makes it difficult to disassemble the aluminum formwork. After repeated use, the surface of the aluminum formwork will be worn, which not only further increases the difficulty of disassembly, but also some concrete may fall off after the aluminum formwork is disassembled, increasing the difficulty of construction. When disassembling the aluminum formwork and concrete, an air pump is used to inflate the one-way valve so that the air pressure in the ventilation groove is greater than the external air pressure, and the air pressure between the aluminum formwork body and the concrete is further greater than the external air pressure. The air pressure quickly generates a gap between the aluminum formwork and the concrete, which is convenient for the staff to quickly disassemble the aluminum formwork. Compared with disassembly by directly applying force, air pressure is less likely to damage the aluminum formwork and the concrete surface, thereby improving construction efficiency. At the same time, after a certain period of use, the partition net can be disassembled and replaced to reduce construction expenses. BRIEF DESCRIPTION OF THE DRAWINGS
