[0031] Embodiment 1:

The screw rod 2 is threadedly connected inside the fixing piece 4, the outside of the bolt 3 is sleeved inside the thermal insulation material 1, and there is an abutment between the inner side of the fixing piece 4 and the outer side of the thermal insulation material 1. The aperture of the mesh form 9 is 2 mm, the aperture of the internal steel mesh 6 is 100 mm, and the aperture of the galvanized wire mesh 10 is 50 mm.
[0033] Specifically, the thermal insulation material 1 is a board similar to rigid foam for heat preservation and sound insulation. The screw rod 2 is used to install the two fixing pieces 4 on both sides of the thermal insulation material 1. The bolt 3 is used to fix the fixing piece 4 on the screw rod 2 to clamp the thermal insulation material 1. The connecting block 5 is used to connect and support the internal steel mesh 6. The internal steel mesh 6 is used to enhance the strength of the entire casting formwork. The fixing plate 7 is used to connect and support the internal connecting piece 8. The internal connecting piece 8 and the external connecting piece 11 cooperate to fix the mesh form 9 and the galvanized wire mesh 10. The mesh form 9 is used to prevent the concrete from leaking out during casting. The galvanized wire mesh 10 is used to support the mesh form 9 to prevent the mesh form 9 from being broken during the casting of concrete. The external connecting piece 11 is fixed on the internal connecting piece 8 by self-tapping screws. The slots 12 are used to facilitate the splicing with another formwork and facilitate the installation construction.
[0034] Embodiment Two:
[0035] An embodiment provided by the present utility model: where the casting formwork can also be constructed without the thermal insulation material 1. Since the thermal insulation layer is installed outside the wall separately later, when the device does not require the thermal insulation material 1, only the remaining parts need to be fixed in the original manner, and each formwork is tied with wire, and finally the concrete can be directly poured.
[0036] Refer to Figure 1 - Figure 4, the splicing component includes a housing 13, the inner side of the housing 13 is fixedly connected to the outside of the thermal insulation material 1, a partition 14 is fixedly connected inside the housing 13, a plurality of springs 15 are fixedly connected to both the left and right sides of the partition 14, a clamping block 16 is fixedly connected between the outer sides of the plurality of springs 15, the outside of the clamping block 16 is rotatably connected inside the housing 13, the outside of the housing 13 is slidably connected inside the card slot 12, and the outside of the clamping block 16 is clamped inside the card slot 12.
[0037] Specifically, the housing 13 is used to connect and protect the internal parts, the partition 14 is for fixing and connecting the springs 15, the springs 15 are used to drive the clamping block 16 to reset and engage with the inside of the card slot 12 to achieve splicing and fixing. The clamping block 16 rotates inside the housing 13, and a protrusion is provided on its inner side to prevent the clamping block 16 from falling off the inside of the housing 13.
[0038] Working principle: When assembling the formwork, first penetrate the screw rod 2 into the thermal insulation material 1, then screw the bolt 3 into the screw rod 2 to drive the fixing piece 4 to contact the thermal insulation material 1, and tighten the bolt 3 so that the two fixing pieces 4 clamp the thermal insulation material 1. Install a plurality of fixing pieces 4 in sequence. Then, snap the inner steel mesh sheet 6 into the groove of the connecting block 5. Next, fix the inner connecting piece 8 to the fixing plate 7 with screws, and place the net form 9 and the galvanized mesh sheet 10 in contact and synchronously on the inner connecting piece 8. Finally, fix the outer connecting piece 11 to the inner connecting piece 8 with self-tapping screws to achieve a quick component. When splicing these formworks at the construction site, align the housing 13 with the card slot 12 and insert it. When the card slot 12 touches the clamping block 16, the clamping block 16 will shrink inward and compress the spring 15. When the housing 13 is inserted to the innermost part of the card slot 12, under the support of the partition 14, the spring 15 will immediately push the clamping block 16 to pop out the clamping block 16 to reset and latch it on the card slot 12. After splicing, pour the concrete into the gap between the inner steel mesh sheet 6 and the thermal insulation material 1. Since the concrete cannot penetrate, the net form 9 will spread by itself inside until it solidifies, and a wall is built. The whole operation is simple and convenient, effectively improving the work efficiency. This pouring formwork is more suitable for public buildings and civil buildings.
[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
