Description

TECHNICAL FIELD

[0001] The utility model relates to civil engineering field, specifically speaking, an aluminium formwork for preventing grout leakage of cast-in-situ concrete of building engineering. BACKGROUND

[0002] In the process of building engineering construction, in order to improve construction quality and construction efficiency, people gradually use aluminium formwork to replace traditional wood formwork. Aluminium formwork has excellent corrosion resistance, light weight, high strength, fireproof and waterproof, convenient assembly and quick installation and disassembly and other characteristics, these advantages make aluminium formwork be widely applied in modern building.

[0003] At present, the aluminium formwork for construction is mostly the panel with smooth surface, connects a piece of standard formwork through bolt or pin, and finally fixes with support system. However, in the actual installation process, due to the influence of construction quality and worker's skill level, the formwork splicing part often appears not to be tight. This can cause grouting material to leak from the joint of aluminium formwork, thereby affecting the pouring quality, and even seriously affect the safety of the whole formwork system.

[0004] When grout leakage occurs, the leakage must be found in time during construction, and the leakage is cleaned. Then, using repair materials such as grouting material or sealant to repair, and using scraper or brush to compact the repair material, to ensure that it is closely attached to the surface of aluminium formwork, and prevent grout leakage again. However, this series of leakage repair work not only causes the waste of labor, but also increases the production cost and construction cost.

[0005] In summary, the existing aluminium formwork technology has certain disadvantages in practical application, especially in formwork splicing and grout leakage prevention. CONTENT OF UTILITY MODEL
