[0022] As shown in Figure 1 , Figure 5 and Figure 6 , as more and more narrow building spaces are gradually utilized, the narrow building spaces are small and cannot leave many workers to erect formworks, and some formworks and support systems occupy a lot of space, which can extremely compress the pouring space or cannot build formworks at all. At present, the formwork assembly for narrow building spaces is mostly customized according to the size of the space to make the formwork of corresponding size to be spliced to form a pouring cavity, which leads to high cost. Therefore, the embodiment one of the utility model provides a formwork assembly for narrow building spaces, which comprises a front formwork 1, a rear formwork 2 and left and right side formworks 3. The front formwork 1, the rear formwork 2 and the left and right side formworks 3 jointly form a pouring cavity. The front formwork 1 and the rear formwork 2 are provided with abutting adjusting members 5 on the two sides. The abutting adjusting members 5 are used to adjust the distance between the front formwork 1 and the rear formwork 2 and simultaneously form a transverse abutting effect on the left and right side formworks 3. The front formwork 1 and the rear formwork 2 are both provided with longitudinal abutting members 6 on the outward end faces. The longitudinal abutting members 6 are used to abut the front and rear formworks 2 to prevent the formwork from leaking grout during pouring.

[0023] The distance between the formworks can be adjusted by the abutting adjusting piece 5 to form the width of the required pouring cavity. When the formworks are removed, the looseness between the front and rear formworks 2 and the pouring concrete gap can be loosened by adjusting the abutting adjusting piece 5. When the distance between the front and rear formworks 2 changes, the left and right side formworks 3 also need to change synchronously, so the left and right side formworks 3 are spliced, and the length of the left and right side formworks 3 is formed according to the width of the pouring cavity; or the length of the left and right side formworks 3 is customized in advance according to the width of the required pouring cavity, and one of the two can be selected according to the actual situation. The end face of the left and right side formworks 3 facing the abutting adjusting piece 5 is provided with a limiting through groove, and the limiting through groove is used for limiting and abutting the abutting adjusting piece 5.

[0024] Specifically, as shown in Figure 1 The abutting adjusting piece 5 includes a plurality of V-shaped hinge parts 51, and the V-shaped hinge parts 51 are jointly provided with a limiting part 52.

Or the abutting end 522 is a telescopic abutting plate (the telescopic abutting plate belongs to the prior art, and will not be described in detail here), which can not only support the left and right side formworks 3 when the formworks are erected, but also loosen the left and right side formworks 3 and the concrete during the formwork removal process, facilitating demolding.
