In building construction, adjustable top braces are widely used in the formwork construction process. However, in some special structure formwork construction structures, adjustable top braces cannot meet the support requirements. For example, when supporting inclined roof formwork, due to The commonly used adjustable top support is only adjustable in height, and its support angle cannot be flexibly adjusted. It is necessary to add inclined pads on the top surface of the adjustable top support. The inclined pads need to be made of wood cutting saws according to the actual needs of the site. There are problems of unreliability and poor stability when using inclined pads for support; in addition, when supporting structures with limited support heights in narrow spaces, such as the support of foundation coupling beam formwork, usually the distance between the foundation coupling beam formwork and the supportable surface The range of the distance between them is 100mm～500mm, and the adjustable top support cannot meet the support requirements. Therefore, the foundation coupling beam formwork can only be supported by wooden squares and pads, and the construction process of this support method is very difficult. It is cumbersome and needs to strictly control the size of the wooden squares and pads. Due to the overall subsidence of the foundation coupling beam after pouring, it is difficult to remove the formwork. As a result, some support items cannot be dismantled, but can only be directly buried in the soil. The structure cannot be reused, resulting in waste of resources. Therefore, there should be provided a top support device that can be flexibly applied in the formwork construction of special structures and whose height and angle can be adjusted.
