Description

Technical Field

[0001] This utility model relates to the field of building formwork splicing technology, specifically to a building formwork splicing anchoring device. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to ensure that concrete structures and components are shaped in the specified positions and geometric dimensions, maintain their correct positions, and bear the self-weight of the formwork and the external loads acting on it. When actually using construction formwork, embedded anchoring devices are required to stably connect the formwork. In actual use, it has the advantages of simple operation, high stability, safety and efficiency.

[0003] In existing technologies, the formwork frame is usually fixed by drilling into the wall and then using cantilever poles to fix the formwork frame. This method of fixing the formwork frame cannot properly secure the formwork, and the formwork cannot withstand too much pressure, so it cannot be used for the construction of large buildings and high-rise buildings.

[0004] As disclosed in Chinese Patent CN201722929U, a formwork anchoring device includes: an embedded plate, a high-strength screw connected to the embedded plate, a climbing cone connected to the high-strength screw, and a load-bearing bolt connected to the climbing cone. The embedded plate has a threaded groove, one end of the high-strength screw is screwed into the groove and threadedly connected to the embedded plate, the climbing cone is a hollow conical cylinder with threads on its inner surface, the other end of the high-strength screw is threadedly connected to the smaller diameter end of the climbing cone, and the load-bearing bolt is threadedly connected to the larger diameter end of the climbing cone. This formwork anchoring device provides a reasonable structural design, is robust and durable, has high tensile strength, is easy to install and use, has a high safety factor, and can effectively fix the formwork. It is suitable for use in various construction sites, especially for high-rise and large buildings.

[0005] However, after prolonged use, the bolts on the anchoring device are prone to loosening, which can cause the template to fall off and cause some inconvenience to the user.

[0006] To address this issue, we propose a building formwork splicing and anchoring device. Utility Model Content

[0017] 1. This building formwork splicing and anchoring device, through the setting of a first internal support mechanism, rotates the first rotating handle, causing the first moving ring to move on the surface of the first hollow threaded rod on the outer surface of the solid rod. Through the rotational installation of the first connecting rod and the second connecting rod on the first connecting piece, the first internal support plate and the second connecting rod, the first internal support plate is pushed open into the formwork. At the same time, the first conical nail on the surface of the first internal support plate is driven into the interior of the formwork, making the internal support more stable and preventing the device from slipping out of the formwork due to vibration. This solves the problem mentioned in the background technology that after long-term use, the bolts on the anchoring device are easily unscrewed, which leads to the formwork falling off and causes certain impacts on users.

[0018] 2. This building formwork splicing and anchoring device, by setting a first internal support mechanism and a second internal support mechanism, when in use, the first internal support mechanism enters the first formwork piece, and the second internal support mechanism enters the interior of the second formwork piece.
