Description

Technical Field

[0001] The utility model relates to the technical field of building template support structures, in particular to a internal angle support structure. Background Art

[0002] Formwork support for building formwork is an important part of the main building construction process. The formwork quality of building formwork is closely related to the quality of concrete forming. If the formwork support is not in place, the formwork will easily deform during the pouring process, resulting in leakage. Especially at the formwork inner corner support, the construction space is narrow and it is difficult for workers to support the formwork. The design angles of the inner corners of different building entities are different, and the number of formwork supports is large. The inner corner of the building is often located on the side of the formwork facing the ground, such as the inverted trapezoidal structure on the top of the pier. The position of the inner corner of the building is special, and it is difficult for workers to control the support angle of the inner corner of the formwork. Faced with different inner corner angles of the main building, the common formwork support method during construction is to specially make inner corner formwork suitable for the inner corner angle and formwork support with special angle. However, the specially made inner corner formwork and formwork support of this method have poor applicability and cannot be turned around, which increases production costs. Utility Model Content

[0005] The technical principle of the utility model is as follows: in the face of different internal corner angles of building entities, workers operate the retractable supporting mechanism to drive the first connecting rod and the second connecting rod to open and close to achieve adjustment of different supporting angles, without the need for workers to manually build the supporting formwork at the internal corner, which is convenient for workers to construct, and at the same time, the internal corner supporting structure has good applicability and can be turned over, reducing the cost of use; in the opening and closing process, the first angle ruler opens together with the first connecting rod, and the workers control the supporting angle by readings on the first angle ruler, which is convenient for workers to control the supporting angle; it solves the problem that the design angles of the internal corners of different building entities are different, the position of the internal corners of the building is special, and it is difficult for workers to control the supporting angle of the internal corners of the formwork.

[0033] The advantages of adopting the above technical scheme are: workers operate the retractable support mechanism to drive the first connecting rod 1 and the second connecting rod 2 to open and close to achieve the adjustment of different support angles. There is no need for workers to manually build the support formwork at the internal corner, which is convenient for workers to construct. At the same time, the internal corner support structure has good applicability and can be circulated, which reduces the cost of use. During the opening and closing process, the first angle ruler 5 and the second angle ruler 6 are opened in turn, and the workers control the support angle through the readings on the first angle ruler 5 and the second angle ruler 6. It is convenient for workers to control the support angle. This solves the problem that the design angles of the internal corners of different building entities are different, the position of the internal corners of the building is special, and it is difficult for workers to control the support angle of the internal corners of the formwork.
