Since one end is connected through the distance adjusting assembly to realize the adjustable distance between the bottom and the top, and the other end is connected through the rotary connecting assembly to realize the rotary connection, the inclination angle of the bottom of the angle adjusting mechanism 3 along the bridge direction is adjustable, thereby achieving the purpose of adjusting the inclination angle of the bottom form 2 along the bridge direction, so that the slope of the bottom form 2 and the bottom of the beam body c along the bridge direction can be matched, and the wood form b does not need to be frequently cut and assembled on site, which is beneficial to save installation time and improve construction efficiency.

[0046] Specifically refer to Figure 7 and Figure 8 In the embodiment, the distance adjusting assembly includes a first telescopic piece 33, the bottom of the angle adjusting mechanism 3 is provided with a first connecting seat 321, the first connecting seat 321 is provided with an adjusting hole 322, and the lower end of the first telescopic piece 33 is connected with the first connecting seat 321 through a first connecting pin arranged in the adjusting hole 322. The first telescopic piece 33 can be telescoped to drive the bottom of the angle adjusting mechanism 3 to rotate up and down around the rotary connection with the top, and the bottom form 2 rotates up and down accordingly, so that the inclination angle of the bottom form 2 can be adjusted. The first connecting pin and the adjusting hole 322 cooperate to realize the sliding connection between the first connecting seat 321 and the first telescopic piece 33, avoiding the first telescopic piece 33 from hindering the rotation of the first connecting seat 321, and the structure is simple and convenient to adjust.

[0047] Further, in the embodiment, the angle adjusting mechanism 3 includes a top plate 31 and a bottom plate 32, the top plate 31 is provided with a nut 34, the upper end of the first telescopic piece 33 is provided with an external thread and is screwed to the nut 34, and the first connecting seat 321 is arranged on the bottom plate 32. By rotating the first telescopic piece 33, the first telescopic piece 33 can be telescoped up and down relative to the top plate 31. After the first telescopic piece 33 is in place, the first connecting seat 321 is connected with the lower end of the first telescopic piece 33 through the first connecting pin, and the structure is simple and convenient to adjust. Of course, in other embodiments, the first telescopic piece 33 can also be a gas cylinder, an oil cylinder or an electric push rod, and the like, which will not be described here.

[0048] Further, in the embodiment, the rotary connecting assembly includes a second connecting seat 323 arranged on the bottom plate 32 and a third connecting seat 311 arranged on the top plate 31, and the second connecting seat 323 and the third connecting seat 311 are connected through a second connecting pin, and the structure is simple and reliable.

[0049] Specifically refer to Figure 4 and Figure 9As a preferred embodiment, the angle adjusting mechanism 3 is provided in plurality, and the plurality of angle adjusting mechanisms 3 are arranged in a bridge direction interval. Since the length of each beam body c is large, the plurality of angle adjusting mechanisms 3 are arranged, which is beneficial to more accurately adjust the inclination angle of the bottom die 2, and meanwhile, the connection strength between the bottom die 2 and the side die 1 can be improved.

[0050] In the embodiment, the inner die for bridge cantilever pouring construction further comprises a height adjusting assembly.

[0051] The height adjusting assembly is used to adjust the distance between the angle adjusting mechanism 3 and the side die 1, and specifically:

[0052] In the embodiment, the height adjusting assembly comprises a second telescopic member 4, the angle adjusting mechanism 3 is connected between the top of the side die 1 through the second telescopic member 4, and the top of the bottom die 2 is provided with a lap joint portion 21, which is lapped with the side die 1.

[0053] When the height of the beam body c changes, the second telescopic member 4 can drive the angle adjusting mechanism 3 and the bottom die 2 to rise and fall as a whole, so as to realize the change of the overall height of the inner die for bridge cantilever pouring construction, thereby meeting the height requirement of bridge pouring. Since the bottom die 2 needs to rise and fall, the lap joint portion 21 is arranged on the bottom die 2, which is beneficial to prevent the gap between the bottom die 2 and the side die 1 from becoming large. The second telescopic member 4 can be a pneumatic cylinder, an oil cylinder or an electric push rod, for example.

[0054] Specifically referring to Figure 5 and Figure 6 In the embodiment, the side die 1 is provided with a first reinforcing rib 11 and a second reinforcing rib 12, the first reinforcing rib 11 and the second reinforcing rib 12 are lapped and a first waist-shaped hole 13 arranged in the height direction of the side die 1 is arranged at the lapped portion, a first locking member (not shown in the figure, for example, a screw or a bolt) for fixing the first reinforcing rib 11 and the second reinforcing rib 12 is arranged in the first waist-shaped hole 13, and the second reinforcing rib 12 is arranged inside the lap joint portion 21.

[0055] The arrangement of the first reinforcing rib 11 and the second reinforcing rib 12 can improve the rigidity of the side die 1 and the lap joint portion 21 of the bottom die 2, so as to avoid deformation and displacement during pouring. When the bottom die 2 needs to rise and fall, the first locking member is loosened first, then the second reinforcing rib 12 is moved up and down to a suitable position, so as to avoid hindering the rising and falling of the bottom die 2, and finally the first locking member is locked again.

[0056] Embodiment two

[0057] Figures 10 to 11 Another embodiment of the inner die for bridge cantilever pouring construction is shown, which is basically the same as the first embodiment, and the difference lies in that: the height adjusting assembly of the embodiment is used to adjust the height of the side die 1, and specifically:

[0058] In the embodiment, the side mold 1 comprises a plurality of detachable side mold modules 14, which are detachably installed on the side mold back frame 15 and arranged along the height direction of the bridge, and the angle adjusting mechanism 3 is adjustable along the bridge direction;

[0059] The top and bottom of the angle adjusting mechanism 3 are provided with second waist-shaped holes 35 arranged along the bridge direction (the second waist-shaped hole 35 on the top plate 31 is not shown, and the second waist-shaped hole 35 on the bottom plate 32 can be referred to), and the side mold 1 and the bottom mold 2 are provided with second locking members 22 (such as screws, bolts, etc.) for fixing the angle adjusting mechanism 3 (the second locking member 22 on the top plate 31 is not shown, and the second locking member 22 on the bottom mold 2 can be referred to), and the second locking member 22 is arranged in the second waist-shaped hole 35. When the second locking members 22 at the top and bottom are loosened, the angle adjusting mechanism 3 can be moved along the bridge direction as a whole, thereby adjusting the height of the bottom mold 2, and the structure is simple and convenient to adjust.

[0060] When the height of the beam body c changes, the height of the side mold 1 can be adjusted by disassembling and assembling the side mold modules 14 (when the height increases, the number of side mold modules 14 is increased, and vice versa, the number of side mold modules 14 is reduced), and the position of the angle adjusting mechanism 3 is adjusted along the bridge direction, and the overall height of the inner mold for bridge beam cantilever pouring construction can also be changed, thereby meeting the height requirements of the bridge pouring.

[0061] Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application. Any skilled person in the art can make many possible changes and modifications to the technical solution of the present application, or modify equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of the present application. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application shall fall within the scope of protection of the technical solution of the present application.
