[0025] The beam side form reinforcement device at the deformation joint position includes a completed cast component 1, a component to be cast 2, a deformation joint between the completed cast component 1 and the component to be cast 2, and a plurality of reinforcement devices, a template 3 is installed on the side of the component to be cast 2, and the plurality of reinforcement devices are arranged along the cross-sectional size of the component to be cast 2;

[0026] The reinforcement device includes a square steel 4, and a fixed steel wedge 5 and a detachable adjustable steel wedge 6 are respectively provided at the upper and lower ends of the square steel 4, and the fixed steel wedge 5 and the adjustable steel wedge 6 are installed on the side of the square steel 4 facing the completed cast component 1, and the fixed steel wedge 5 and the adjustable steel wedge 6 abut against the completed cast component 1, and the side of the square steel 4 facing the template 3 abuts against the template 3. During the construction of the beam side form reinforcement device at the deformation joint position, the template 3 to be fixed on the component 2 to be cast is processed, the adjustable steel wedge 6 is removed from the square steel 4, and installed at the component 2 to be cast along the deformation joint, and the square steels 4 are inserted into the deformation joint gap one by one from bottom to top (if the fixed steel wedge 5 is installed at the lower end of the square steel 4, the deformation joint is inserted from bottom to top, and if the fixed steel wedge 5 is installed at the upper end of the square steel 4, the deformation joint is inserted from top to bottom. In this embodiment, in order to facilitate the installation of the adjustable steel wedge 6, the fixed steel wedge 5 is installed at the lower end of the square steel 4), and the spacing between each square steel 4 is calculated and determined according to the cross-sectional size of the template 3. Then install the upper adjusting steel wedge 6 to ensure that the fixed steel wedge 5 and the adjusting steel wedge 6 are both in contact with the completed cast component 1, and the square steel 4 is in contact with the formwork 3, thereby reinforcing the formwork 3. Then the concrete can be poured and cured. When the formwork removal conditions are met, the adjusting steel wedge 6 is loosened, the square steel 4 is pulled out, and the formwork 3 is disassembled, and the formwork 3 is lifted up as a whole to complete the construction. This reinforcement device has the characteristics of ordinary materials, simple production, low cost, easy operation, and high performance guarantee rate. In addition, the device is easy to use, reliable in performance, convenient and practical, and low in cost. It is very easy to popularize the construction process of beam side formwork at the deformation joint position.

[0027] In the utility model, the fixed steel wedge 5 and the adjusting steel wedge 6 are triangular in shape, and when fixed, the long hypotenuse 7 of the fixed steel wedge 5 and the adjusting steel wedge 6 abuts against the completed cast component 1, so that it can also be applicable to deformation joints of different widths. At the same time, the long hypotenuse 7 is covered with a rubber gasket with a thickness of 5 mm, which can prevent the fixed steel wedge 5 and the adjusting steel wedge 6 from damaging the side of the completed cast component 1. At the same time, the elastic force generated by the rubber gasket can make the fixed steel wedge 5 and the adjusting steel wedge 6 abut against the completed cast component 1 more tightly.

[0028] In the utility model, the fixed steel wedge 5 is welded and fixed to the lower end of the square steel 4, and the adjusting steel wedge 6 is detachably installed on the upper end of the square steel 4. In this way, when installing the square steel 4, the square steel 4 is inserted into the deformation joint from bottom to top, which is convenient for the subsequent installation of the adjusting steel wedge 6.

When installing the adjusting steel wedge 6, the connecting piece 10 of the adjusting steel wedge 6 is inserted into the groove bar 11 from the upper opening, and the adjusting steel wedge 6 is moved down along the groove bar 11 until the long hypotenuse 7 of the adjusting steel wedge 6 abuts and presses against the completed cast component 1, and the bolt 9 is screwed into the threaded hole 8 until the end of the bolt 9 presses against the connecting piece 10, and at this time, the position of the adjusting steel wedge 6 is fixed, and at the same time, the square steel 4 presses against the formwork 3, thereby achieving the reinforcement effect of the formwork 3. This installation method of adjusting the steel wedge 6 is also applicable to completed cast components 1 of different heights and is easy to install.

[0030] This reinforcement device has been verified by visual inspection on site after the casting is completed and the formwork is removed to have the ability to accurately control the cross-sectional dimensions of concrete components and reduce the difficulty of installing and removing the beam side formwork 3 at the deformation joint position. It has well coped with the challenges of inconvenient installation and reinforcement of formwork 3, large deviation of component cross-sectional dimensions, and uneven beam side. It has reduced the construction difficulty, greatly improved the construction efficiency, and saved construction time; the formwork 3 is easy to remove, avoiding material waste; the concrete surface is flat, saving labor for re-repair after demolding.
