[0027] The following is combined with Figure 1-3 This application is described in further detail.

[0028] See also Figure 1-3The decorative concrete eaves formwork includes a base plate 1 with a stepped structure. Both ends of the base plate 1 are provided with side plates 4 that are slidably connected to the base plate 1 through a connecting structure. The base plate 1 and the side plates 4 on both sides together form an eaves formwork structure with a cavity inside.

[0029] A sealing assembly is installed at the joint between the side panel 4 and the upper surface of the bottom plate 1. By installing the sealing assembly at the connection between the side panel 4 and the bottom plate 1, sealing is performed to avoid leakage of concrete poured into the eaves formwork from the gap at the connection between the side panel 4 and the bottom plate 1 as much as possible.

[0030] Adjustment components for adjusting the position of the side panels 4 are fixedly connected to the outer walls at both ends of the bottom plate 1. The adjustment components are used to adjust the distance between the two side panels 4, so that users can freely adjust according to the size of the eaves, which is convenient for users to use.

[0031] The adjustment assembly includes two groups of ear plates 7 fixedly connected at both ends of the base plate 1, and a connecting shaft 8 with a threaded end is fixedly connected between the two ear plates 7 in each group. The connecting structure is sleeved on the connecting shaft 8 and slidably connected to the connecting shaft 8.

[0032] An elastic structure is sleeved on the middle section of the connecting shaft 8, and internal threaded tubes 11 are screwed on both ends of the connecting shaft 8 to limit the position of the side panels 4. The user can squeeze the side panels 4 on both sides toward the center of the connecting shaft 8 by screwing the internal threaded tubes 11, thereby pushing the side panels 4 on both sides to slide along the connecting shaft 8, and adjusting the distance between the two side panels 4.

[0033] A scale mark 16 is further provided on one end of the bottom plate 1 , and the user can calculate the distance between the two side plates 4 by the scale mark 16 during the adjustment process, making it more convenient for the user to use.

[0034] Reference Figure 1 Two internal corner pads 2 and one external corner pad 3 are fixedly connected to the upper surface of the bend of the base plate 1. The upper surfaces of the internal corner pads 2 and external corner pads 3 are respectively in a downwardly concave or upwardly convex arc structure. The internal corner pads 2 and external corner pads 3 are provided to chamfer the bend of the overhanging eaves, making it more aesthetically pleasing.

[0035] Reference Figure 1 and Figure 2 The connection structure includes connecting plates 5 extending from both ends of the side panels 4. The connecting plates 5 are provided with chute 6 that can be snapped onto the end of the bottom panel 1. The chute 6 provided on the connecting plates 5 is snapped onto the bottom panel 1, so that the bottom of the side panels 4 can fit tightly against the upper surface of the bottom panel 1, greatly improving the sealing performance of the connection between the side panels 4 and the bottom panel 1.

[0036] Reference Figure 2The connecting plate 5 is provided with a through hole having an inner diameter equal to the diameter of the connecting shaft 8. The connecting plate 5 is sleeved on the connecting shaft 8 through the through hole and is slidably connected to the connecting shaft 8. The connecting plate 5 is slidably connected to the connecting shaft 8 through the through hole, so that the connecting plate 5 can be slid along the length direction of the connecting shaft 8, thereby driving the two side plates 4 to move toward or in opposite directions, thereby adjusting the distance between the two side plates 4.

[0037] Reference Figure 2 The elastic structure includes a spring 9 sleeved on the middle section of the connecting shaft 8. Slide sleeves 10 are fixedly connected to both ends of the spring 9. The ends of the two slide sleeves 10 that are separated from each other respectively abut against the connecting plates 5 on both sides. The spring 9 is configured to push the two side panels 4 from the middle toward the sides, so that the two side panels 4 are in an open state when not in use. At the same time, after the user pushes the side panels 4 toward each other from both sides via the internally threaded tubes 11, the spring 9 can use its elastic force to push the slide sleeves 10 and the internally threaded tubes 11 in the opposite direction to clamp and secure the side panels 4.

[0038] Reference Figure 3 A push ring 12 is installed at one end of the internally threaded tube 11 near the connecting plate 5. A bearing 13 is embedded in the push ring 12. The outer ring of the bearing 13 is fixedly connected to the push ring 12, and the inner ring of the bearing 13 is fixedly connected to the outer wall of the internally threaded tube 11. The push ring 12, which is rotatably connected to the internally threaded tube 11 through the bearing 13, is used to push the side plate 4 to move and adjust the position of the side plate 4. Since the push ring 12 can rotate, the user does not need to drive the push ring 12 to rotate synchronously when screwing the internally threaded tube 11, which can greatly reduce the resistance when the user screws the internally threaded tube 11.

[0039] Reference Figure 3 The sealing assembly includes a sealing strip 14 fixedly connected to the joint between the side panels 4 and the upper surface of the bottom panel 1. A notch 15 is reserved at the bottom of the sealing strip 14 for the external corner bead 3 to pass through. The sealing strip 14 is provided to improve the sealing performance of the joint between the side panels 4 and the bottom panel 1, and the notch 15 is provided to fit the upper surface of the external corner bead 3.

[0040] The implementation principle of the present application is: when the user needs to adjust the spacing between the two side panels 4, the internal threaded tubes 11 screwed on both ends of the connecting shaft 8 can be screwed, so that the two internal threaded tubes 11 push the push ring 12 to move toward the middle section of the connecting shaft 8 under the action of the thread until the two side panels 4 are adjusted to a suitable spacing. At this time, the two sides of the side panels 4 are respectively clamped by the push ring 12 and the sliding sleeve 10 connected to the end of the spring end 9, and are relatively fixed to the connecting shaft 8. The user can install the eaves template formed by the side panels 4 and the bottom plate 1 on the eaves of the house to pour concrete, thereby avoiding the problem that the existing eaves template cannot be adjusted according to the size of the house and is inconvenient for users to use.
