Composite building template

Abstract

The present invention discloses a composite building template, and belongs to the building template. The composite building template structurally comprises a face plate and a side frame, wherein the side frame is arranged around the face plate and comprises an upper side frame body, a lower side frame body, a left side frame body and a right side frame body; the upper side frame body, the lower side frame body, the left side frame body and the right side frame body are assembled and connected; the face plate is made of a modified PC plastic material while the side frame is made of aluminum alloy sections. The composite building template is light, inexpensive, convenient and easy to assemble; with the assembling type structure, the specifications of the composite building template are rich; the side frame, a crosswise back ridge and lengthwise back ridges are made of aluminum alloy sections, the strength is high, and the integrated using cost is low; the product life cycle is long, components are of an assembling type structure, and the product is very easy to maintain, only components at damaged positions need to be replaced, and thus the life cycle is greatly prolonged; the face plate is made of the modified PC plastic material, the bonding force of the template and concrete is small, the template is labor-saving in removal and easy to clean, and smearing of template oil is avoided.

Description

technical field [0001] The invention relates to a building template, in particular to an assembled aluminum-plastic composite building template. Background technique [0002] At present, the similar formwork circulating in the market mainly includes combined steel formwork, all-steel large formwork, and aluminum alloy formwork. These formworks have high strength and good rigidity, and can be recycled for more than 200 times, but combined steel formwork and all-steel formwork are corrosion-resistant The performance is not good, and the weight per unit area is very heavy, reaching 50kg / ㎡, and the weight per unit area of ​​the aluminum alloy formwork also reaches 27kg / ㎡, and the installation and disassembly must rely on lifting equipment. The price of aluminum alloy formwork is relatively high, and the price per square meter is more than 1,000 yuan. Because the price is too high, it is less used in the domestic construction market at present. Although the price of wood formwor...

But it also has its disadvantages: first, due to the limitation of its manufacturing process, the specifications are not rich enough, and there are only a few specifications, and it is difficult to meet the requirements of some buildings with complex shapes; second, the weight per unit area is too heavy to achieve manual transfer between floors , must rely on hoisting equipment and other mechanical equipment to increase construction costs; third, the price is high, resulting in high construction cost sharing; fourth, even if a part of the formwork is damaged, the entire formwork will be scrapped; fifth, the formwork and concrete have a strong bonding force and must be used Template oil, increase material cost and labor cost

[0005] In addition to the disadvantage of wasting forest resources, wood formwork and bamboo plywood also have to be constructed on site during construction. The quality of the project depends on the technical level of the operators, and the randomness is large, which is easy to cause defects in the quality of the project.
