Description

Integrated molding aluminum alloy building template

Technical field

The invention relates to the technical field of aluminum alloy building formwork, in particular to a structure of an integrally formed aluminum alloy building formwork unit and a forming method thereof.

Background technique

Building formwork is the main tool for the construction of concrete structures. The formwork technology directly affects the quality and cost of building works, so it is an important content to promote the progress of building technology. At present, the main materials of building formwork are: 1. Wooden formwork, light in weight and good in versatility; but its construction effect is not good. Concrete surface generally requires secondary batching operation. In addition, wood formwork consumes a lot of wood, which is not good for environmental protection. Second, the plastic template is light in weight and relatively low in cost, but its strength and stiffness are insufficient. 3. The steel formwork has good strength and rigidity, but it is too heavy for construction. 4. Aluminum formwork has the advantages of light weight, high strength, high recyclability, fully recyclable materials, and environmental protection. In recent years, it has become more and more popular among builders in China.

According to surveys, the current production methods of aluminum templates at home and abroad are made of aluminum profiles or aluminum plates (mainly T6 heat-treated aluminum alloy 6061) as raw materials, and they are formed by cutting, punching, welding and orthopedic processes (see FIG. 6) of the present invention, wherein the welding process is the most time-consuming and power-consuming. The welding aluminum template has the following disadvantages:

(1) The production cost of welded aluminum formwork is high; the main reasons are: a). Welded aluminum formwork uses semi-finished products such as aluminum profiles or aluminum plates as raw materials. Compared with aluminum ingot raw materials, its price is much higher, that is, welded aluminum. The raw material cost of the template is high; b). The welding process of the welding aluminum template is very inefficient and consumes large power, which results in high process costs and energy consumption costs. In addition, photoelectricity and smoke generated during the welding process have a large environmental pollution, and Conducive to green.

(2) The structural rigidity of the welded aluminum template is insufficient, and the deformation and bumps (damages) are serious during use (case investigation> 25%); the main reason is that the welded aluminum template strengthens the rigidity of the template structure. The ribs or ribs cannot be arranged densely, otherwise the cost of the template welding process will be greatly increased. In general, the deformation of the aluminum formwork during use can be corrected by mechanical orthotics, but if the formwork is damaged, it is difficult to repair or the cost of repair is high, so the severely damaged formwork can only be scrapped. . Most of the damage locations of aluminum formwork occur at the die edge and die angle of the aluminum formwork, especially the die angle is extremely prone to bump damage during handling and construction. Once the mold edges and mold corners are damaged, slurry leakage will easily occur during the cement pouring process, which will affect the construction quality. In addition, the leakage will also greatly increase the cleaning costs of the aluminum formwork after demoulding.

(3) The use cost of welding aluminum template is too high. The aluminum formwork used in the construction aluminum formwork project is divided into standard board, non-standard board and special-shaped board; standard board can be reused in different construction projects (high reusability and low use cost), and non-standard board and special-shaped board are generally It cannot be used universally. When a construction project is finished, it may be discarded (repeated utilization rate is low, and the use cost is high); therefore, increasing the proportion of the standard board used in the construction formwork project is the most practical and effective way to reduce the cost of aluminum formwork. The standard plate of welded aluminum template is generally designed and made as large as possible (such as 400 * 2400mm, 400 * 1100mm, 150 * 2400mm, etc.) to reduce processing time and production costs (large aluminum template and small aluminum template need the same Processing steps: cutting, blanking, punching, welding, orthopedic, etc., so the unit cost of making a large piece of welded aluminum template is lower than that of a small piece of welded aluminum template); The size span is too large. In order to meet the actual size requirements of construction projects, a large number of non-standard plates and special-shaped plates (usually about 30%) are required to be used with them, which has caused the overall cost of welding aluminum formwork projects to be too high.

Patent number: 201720132590.2 discloses a new aluminum profile wall template, which relates to the aluminum profile structure for construction. It includes a one-time formed rectangular panel casting with a frame plate, an end plate, and a main rib. The frame plate, the end plate and the main rib, and the ribs hinged on the main rib are provided on the back of the panel. The feature is that the main rib is a ladder. The shape of the hollow structure, said ribs are hinged to the main ribs in a certain ratio in order to widen the density from the bottom to the top. The beneficial effect of this patent is that it uses a one-time molding frame structure, and the main ribs and the ribs are made of hollow tubes. There are ribs at a certain proportion of density from the bottom to the top, which increases the force of the bottom of the template and makes the template even and firm.

However, the patent also has the following disadvantages: only the frame structure of the template is integrally formed, and it is a non-integral structure with the main ribs and ribs. Therefore, the strength and rigidity of the template structure are not substantially improved; in addition, it also requires The secondary assembling or welding of the main ribs and the ribs separately is very expensive.

Patent number: 201620690933.2 discloses an aluminum formwork structure including an aluminum formwork unit. The aluminum formwork unit includes a main board and connection boards provided on both sides of the main board. The main board includes a work surface and a support surface. The connection board It includes a connecting side, a working side and a supporting side; the working side is connected with the working surface to form a smooth surface. By adopting the above scheme, the working surface of the aluminum formwork is made into a smooth surface through precision die-casting technology, so that the wall after the pouring molding has a smooth surface directly. The beneficial effect of the invention is: after the material aluminum template is die-casted by precision die-casting technology, an aluminum template unit with a structural strength that is similar to or even better than the existing one is formed. The physical properties on the working surface and working side have been changed to make the working surface and working side smoother, so that the wall surface after pouring can meet the needs of the construction staff for the next operation without further leveling treatment; and aluminum The structural setting of the formwork unit also has a smooth and smooth effect on the wall surface after pouring.

However, it should be pointed out that through the entire specification, it can be known that the precision die casting described in this application is not pressure casting. Pressure casting refers to the use of a die casting machine to inject liquid aluminum alloy into the mold cavity at a high speed and let the aluminum liquid in the mold cavity. The process of internal solidification molding, and the application is the use of solid aluminum plate material stamping by a stamping machine, the complete molding process also involves welding and other processes, the production cost is relatively high; In addition, the aluminum template produced by this process, which There is no substantial increase in structural stiffness.
