A composite structure aluminum alloy formwork

Abstract

The invention discloses an aluminum alloy template with a composite structure. The aluminum alloy template with the composite structure comprises a main template (1), a ladder-shaped connecting slot (3) and a lock catch (4), wherein the ladder-shaped connecting slot (3) is connected in the middle of the lower part of the main template (1); the lock catch (4) is respectively in locked connection with the main template and the ladder-shaped connecting slot (3). The aluminum alloy template with the composite structure has the beneficial effects that the templates are connected by the ladder-shaped connecting slot, so that the connection is firmer, the sealing degree is better, a leakage phenomenon is almost not produced during concrete casting, and the final quality of the building product is ensured. Moreover, the template can be reused, the cleaning is time-saving and labor-saving, and the service life of the template is also greatly prolonged; the connecting construction efficiency adopting the ladder-shaped connecting slot is greatly improved by 3-5 times in comparison with the existing construction efficiency.

Description

technical field [0001] The invention belongs to building templates, in particular to the technical field of connection structure and composition structure system of aluminum alloy building templates. Background technique [0002] Since the aluminum alloy formwork was born in the United States in 1962, it has a history of 50 years of application. It has been widely used in the buildings of developed countries such as the United States and Canada, as well as emerging industrial countries such as Mexico, Brazil, Malaysia, South Korea, and India. In this field of technology, my country is currently in its infancy. [0003] Compared with the national standard "Technical Specifications for Composite Steel Formwork" (GB50214-2001), the existing structural system of aluminum alloy formwork in China is essentially a replica of the technology of composite steel formwork, with the same structural features and connection methods. In view of the problems that have occurred in the actua...

Problems solved by technology

[0005] The purpose of the present invention is also to use the connection structure of this aluminum alloy formwork to form a kind of structure that meets the requirements of the national standards "Building Modular Harmonization Standard", "Residential Building Modulus Harmonization Standard" and "Factory Building Modulus Harmonization Standard". The composition system of the aluminum alloy formwork includes the internal angle formwork, the external angle formwork and the width adjustment ladder-type connection groove, and these components and related components form the vertical connection of two internal angles, the vertical connection of three internal angles, and the vertical connection of two external angles. Thereby overcoming the traditional combined steel formwork or the existing aluminum alloy formwork described in the background technology, the problems of poor tight seam leakage, low formwork processing efficiency and high cost, short cycle life of the formwork and high labor cost for disassembly and assembly
