Windows are installed along the outer edge, forming three sides vertically to form a bay window. The bay window has the following advantages: expanding the field of vision and being conducive to viewing; facing beautiful scenery, with an open field of vision and high indoor and outdoor permeability, which can fully meet people's sensory enjoyment and improve the artistic taste of the building. Beautifying the indoor environment, the bay window increases the area of the window sill due to the outward projection, and decorating it can effectively beautify the indoor environment. Increasing the usage function; the drying function.

[0003] In the construction of bay windows in the prior art, the upper floating board and the lower floating board are poured in two or even multiple times. First, the lower formwork for pouring the lower floating board is set up, and the lower floating board is poured in the lower formwork. After the structure of the lower floating board is formed and solidified, the lower formwork is removed, and then the lower floating board is used as a support to set up the upper formwork for pouring the upper floating board. After pouring the upper floating board in the upper formwork, the upper formwork is removed. This construction method of the bay window has cumbersome steps and a slow construction progress. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a bay window formwork reinforcement system and a construction method thereof to solve the technical problems of cumbersome construction steps and slow construction progress in the construction of bay windows in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by a bay window formwork reinforcement system of the present invention is as follows:

[0007] Brackets: Fixed on the lower floor slab, several brackets are arranged in parallel front and back. The brackets are provided with overhanging arms extending outward, and the brackets are fixed between the upper floor slab and the lower floor slab through top support rods;

[0008] Support platform: Fixed on the overhanging arms of the brackets;

[0009] Bottom formwork of the lower floating board: Supported on the support platform;

[0010] First side formwork: Fixed on the support platform;

[0011] Second side formwork: Fixed relatively to the first side formwork. The first side formwork and the second side formwork form a pouring cavity for the side plates of the lower floating board;

[0012] Third side formwork: Fixed on the support platform. The bottom formwork, the first side formwork, and the third side formwork form a pouring cavity for the bottom plate of the lower floating board;

[0013] Upper floating plate bottom formwork: Suspended below the overhanging arm of the support.

[0014] Fourth side formwork: Fixedly arranged relative to the lower floor slab.

[0015] Fifth side formwork: Fixedly arranged relative to the fourth side formwork. The fourth side formwork and the fifth side formwork form a casting cavity for the side plates of the upper floating plate.

[0016] Sixth side formwork: Fixedly arranged relative to the upper floating plate bottom formwork. The upper floating plate bottom formwork, the fourth side formwork, and the sixth side formwork form a casting cavity for the bottom plate of the upper floating plate.

[0017] Advantageous effects: The bay window formwork reinforcement system of the present invention can simultaneously form the lower floating plate of the upper bay window, the side plates of the lower floating plate of the upper bay window, the upper floating plate of the lower bay window, and the side plates of the upper floating plate of the lower bay window. Moreover, the formwork is fixed by the support platform on the support or the overhanging arm of the support, with relatively high support stability. And when pouring using the bay window formwork reinforcement system of the present invention, it is possible to simultaneously pour the lower floating plate of the upper bay window, the upper floating plate of the lower bay window, the side plates of the upper floating plate of the lower bay window, and the side plates of the lower floating plate of the upper bay window, saving time and effort in pouring and having a relatively high pouring efficiency.

[0018] Further, the support includes a first horizontal rod fixedly connected to the lower floor slab, a first vertical rod fixedly connected perpendicularly to the first horizontal rod, a second vertical rod fixedly connected perpendicularly to the first horizontal rod, and a second horizontal rod fixedly connected perpendicularly to the first vertical rod and the second vertical rod. The overhanging arm is the second horizontal rod; a first inclined rod fixedly connected between the first horizontal rod and the first vertical rod, and the first horizontal rod, the first vertical rod, and the first inclined rod enclose a triangular structure; a second inclined rod is fixedly connected between the second vertical rod and the second horizontal rod, and the second vertical rod, the second horizontal rod, and the second inclined rod enclose a triangular structure.

[0019] Advantageous effects: The support includes a triangular structure formed by the first horizontal rod, the first vertical rod, and the first inclined rod, and also includes a triangular structure formed by the second vertical rod, the second horizontal rod, and the second inclined rod. Since the triangular structure has strong stability, the support has relatively high structural stability.

[0020] Further, the support is arranged on the front side or the rear side of the top support rod. The first vertical rod and the second vertical rod of the support are respectively arranged corresponding to the top support rod in the front-rear direction, and the first vertical rod is fixedly connected to the top support rod, and the second vertical rod is fixedly connected to the top support rod.

[0021] Advantageous effects: Fixing the support on the top support rod can ensure the fixing stability of the support and provide a basis for setting a support platform on the support.

[0022] The support platform includes a first support plate fixed on the cantilever. A number of vertical poles are fixed on the first support plate. The top of the vertical poles is fixed with a second support plate. Square timbers are laid on the second support plate. The bottom formwork of the downward-sloping slab is supported on the square timbers.
