Description

TECHNICAL FIELD

[0001] The utility model relates to the field of abutment template, especially a kind of anti-deformation reinforcing support device of abutment template. BACKGROUND

[0002] In modern bridge construction, as an important part of bridge, the construction quality of abutment is directly related to the overall stability and service life of bridge. As a key tool for abutment construction, abutment template plays a crucial role in the process of concrete pouring. However, at present, in the construction of abutment, the abutment template is prone to deformation, which seriously affects the construction quality and progress.

[0003] The traditional abutment template reinforcing support method is relatively simple, mostly relying on limited external support structure and the rigidity of the template itself. In the process of concrete pouring, as the concrete is continuously poured in, the huge lateral pressure generated will cause the template to bear high-strength force. The existing support method cannot effectively disperse and resist these pressures, resulting in excessive local stress on the template, causing the template to deform, thus the problem of easy deformation of the template exists.

[0033] Embodiment 2

[0034] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the second embodiment of the utility model is based on the previous embodiment, and the support mechanism 3 includes the limit frame 305 slidably connected to the outer surface of the connecting frame 205, the outer surface of the limit frame 305 is fixedly connected with the moving frame 302, and the inner wall of the moving frame 302 is slidably connected with the telescopic rod 303.
