Description

Technical Field

[0001] The utility model relates to the technical field of aluminum templates, in particular to an aluminum template connection structure. Background Art

[0002] Aluminum alloy formwork is called concrete engineering aluminum alloy formwork, which 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. Aluminum alloy formwork is mainly made of aluminum alloy profiles, which are 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 device.

[0003] For example, the authorization announcement number "CN210976620U" is named an aluminum formwork connection structure. Although the two sides of the connecting plate are respectively fitted with the side shapes of the first aluminum formwork and the second aluminum formwork, the connecting plate has a first number of openings. The aluminum formwork connection structure not only avoids opening holes on the aluminum formwork, but also effectively prevents leakage of the aluminum formwork, ensures the cleanliness of the back of the formwork, and does not require additional cleaning of the back of the formwork after pouring concrete. However, the existing aluminum formwork connection structure still exists. It uses the engagement between the pin and the clamping arm to connect two adjacent aluminum formworks. However, because the pin is movable in the clamping arm and the pin lacks a structure that can be fixed, during the installation and use of the aluminum formwork, once the pin becomes loose or the operator accidentally pulls out the pin, the clamping arm fixed between the two connected aluminum formworks will fall off, so the aluminum formwork is prone to loose connection.

[0004] At the same time, the existing aluminum formwork connection structure uses two clamping arms to hold and fix the supporting angles of the connected aluminum formworks, but the top and bottom ends of the two adjacent supporting angles lack limiting components. After the aluminum formwork is fixed, when mortar needs to be injected into the inside or cement is poured to shape it, the vertical force of the aluminum formwork will increase because of the large mass of the cement mortar. Therefore, the two connected supporting angles can easily slip off each other in the vertical direction, causing the aluminum formwork after the overall connection to fall apart. Therefore, the aluminum formwork connection structure greatly affects the safety of the formwork installation. Utility Model Content
