Figure 2 As shown), conventional inner molds cannot be used for direct casting. The steel molds at the toothed block locations must be disassembled on-site, and the wooden molds cut into appropriate shapes for assembly (e.g., Figure 3 As shown in the figure, the pouring is completed.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1 Figures 4 to 16 This invention illustrates one embodiment of the continuous beam inner mold of the present invention. The continuous beam inner mold of this embodiment includes a top mold 1, corner molds 5 disposed on both sides of the top mold 1 in the transverse direction, and an adjustable back frame 6 for supporting the top mold 1 and the corner molds 5; wherein, The top mold 1 includes a top mold body 11, a tooth block bottom mold 12, a first tooth block side mold 13, and a tooth block end mold 14. The tooth block bottom mold 12 is rotatably connected to the top mold body 11 along the transverse bridge direction on one side. The first tooth block side mold 13 is slidably attached to the top mold body 11 along the transverse bridge direction and is rotatably arranged along the longitudinal bridge direction. The tooth block end mold 14 is slidably attached to the top mold body 11 along the longitudinal bridge direction and is rotatably arranged along the transverse bridge direction. The corner mold 5 includes a corner mold body 51 and a second tooth block side mold 52. The second tooth block side mold 52 is slidably attached to the corner mold body 51 in the transverse bridge direction and is rotatably arranged in the longitudinal bridge direction. The bottom mold 12 of the tooth block, the first side mold 13 of the tooth block and the end mold 14 of the tooth block can be rotated to a flattened state to form a top mold 1 with the top mold body 11; the second side mold 52 of the tooth block can be rotated to a flattened state to form a corner mold 5 with the corner mold body 51. The bottom mold 12, the first side mold 13, the end mold 14, and the second side mold 52 of the tooth block can be rotated to form an enclosed cavity for casting the tooth block. It should be noted that the longitudinal direction of the bridge is the length direction of the bridge, while the transverse direction is the width direction of the bridge.

[0042] For details regarding the continuous beam inner formwork in this embodiment, please refer to [link / reference]. Figure 9 When the continuous beam segment 8 has no toothed blocks, the toothed block bottom mold 12, the first toothed block side mold 13, and the toothed block end mold 14 are in a flattened state, cooperating with the top mold body 11 to form a flat top mold 1. The second toothed block side mold 52 is also in a flattened state, cooperating with the corner mold body 51 to form a flat corner mold 5, which can be directly poured; see details. Figure 4 , Figure 5 , Figure 7 and Figure 8 When the continuous beam segment 8 is designed with toothed blocks, the bottom mold 12 of the toothed block is rotated downwards until the angle is consistent with the angle of the toothed block in the longitudinal direction of the bridge. The rotation axis of the bottom mold 12 of the toothed block is used as the positioning reference to determine the position of the inner mold in the longitudinal direction of the bridge. According to the shape and position of the toothed block, the angle and position of the first toothed block side mold 13, the second toothed block side mold 52 and the toothed block end mold 14 are adjusted to form a cavity for casting the toothed block. The continuous beam segment 8 with toothed blocks can be cast, and there is no need to repeatedly cut and assemble the wooden mold, which helps to save construction time and improve construction efficiency.

[0043] Furthermore, in this embodiment, the adjustable back frame 6 is respectively provided with a first telescopic support assembly 61 supporting the bottom mold 12 of the tooth block, a second telescopic support assembly 62 supporting the end mold 14 of the tooth block, a third telescopic support assembly 63 supporting the side mold 13 of the first tooth block, and a fourth telescopic support assembly 64 supporting the side mold 52 of the second tooth block. The first telescopic support assembly 61, the second telescopic support assembly 62, the third telescopic support assembly 63, and the fourth telescopic support assembly 64 respectively drive the bottom mold 12 of the tooth block, the end mold 14 of the tooth block, the first side mold 13 of the tooth block, and the second side mold 52 of the tooth block to rotate to a flattened state or an enclosed state.

[0044] See details Figures 10 to 13 When the continuous beam segment 8 without toothed blocks is being poured, the first telescopic support assembly 61 extends upward, causing the toothed block bottom mold 12 to rotate upward to a flattened state and providing reliable support for the toothed block bottom mold 12. Correspondingly, the third telescopic support assembly 63 extends, causing the first toothed block side mold 13 to rotate upward to a flattened state and providing reliable support for the first toothed block side mold 13. The second telescopic support assembly 62 causes the toothed block end mold 14 to rotate upward to a flattened state, and the fourth telescopic support assembly 64 causes the second toothed block side mold 52 to also rotate upward to a flattened state.

[0045] See details Figures 14 to 16 When the continuous beam segment 8 has toothed blocks and is being poured, the first telescopic support component 61 contracts, causing the bottom mold 12 of the toothed block to rotate downwards to an enclosed state. The third telescopic support component 63 contracts, causing the side mold 13 of the first toothed block to rotate downwards to an enclosed state. The second telescopic support component 62 causes the end mold 14 of the toothed block to rotate downwards to an enclosed state. The fourth telescopic support component 64 causes the side mold 52 of the second toothed block to also rotate downwards to an enclosed state. The structure is simple, reliable, and easy to adjust.

[0046] Specifically, such as Figure 10 As shown, in this embodiment, the fourth telescopic support assembly 64 can be used to support the second tooth block side mold 52 in a flattened state; Specifically, such as Figure 14 As shown, when the second tooth block side mold 52 rotates to the enclosed state, the fourth telescopic support assembly 64 can be used to support the tooth block bottom mold 12 (when the second tooth block side mold 52 rotates to the enclosed state, the tooth block bottom mold 12 also rotates to the enclosed state). The fourth telescopic support assembly 64 supports both the flattened second tooth block side mold 52 and the enclosed tooth block bottom mold 12, achieving dual use. Together with the first telescopic support assembly 61, it can provide reliable support for the enclosed tooth block bottom mold 12.

[0047] In this embodiment, the first telescopic support assembly 61 includes a first top plate 611 and two first telescopic support members 612 (of course, the number of the two first telescopic support members 612 can also be adjusted in other embodiments). Each first telescopic support member 612 is arranged at intervals along the bridge direction on the adjustable back frame 6 and the top of the first telescopic support member 612 is hinged to the first top plate 611.

[0048] See details Figure 12 and 13 When the continuous beam segment 8 has no toothed blocks, each of the first telescopic support members 612 extends upward, driving the first top plate 611 to rotate and rise as a whole, thereby providing good support for the toothed block bottom mold 12. After the casting is completed, the side mold 2 and the side mold back frame 7 are first rolled inward, and then the inner mold is lowered as a whole to achieve demolding.

[0049] See details Figure 16 When the continuous beam segment 8 has toothed blocks, the two first telescopic supports 612 retract downwards by unequal lengths, causing the first top plate 611 to rotate downwards and tilt. The tilt angle matches the enclosed toothed block bottom mold 12, thus providing good support for the toothed block bottom mold 12. The structure is reasonable and effective. After the casting is completed, the side mold 2 and the side mold back frame 7 are first pulled inwards, and the first telescopic supports 612 further retract downwards. Then, the inner mold is lowered as a whole to achieve demolding.

[0050] Specifically, such as Figure 16 As shown, in this embodiment, the second telescopic support assembly 62 includes a second support member 621, which is detachably mounted on the adjustable back frame 6; specifically as follows... Figure 18 As shown, or, The second telescopic support assembly 62 includes a second telescopic support member 622, the top of which is hinged to the toothed block end mold 14.

[0051] When the second telescopic support assembly 62 uses the second support member 621, for the continuous beam segment 8 without toothed blocks, the second support member 621 is disassembled, and the toothed block end mold 14 is rotated upward to a flattened state. The first telescopic support member 612 extends upward to drive the toothed block bottom mold 12 to rotate upward to a flattened state, and the toothed block bottom mold 12 can be used to provide support for the toothed block end mold 14. For the continuous beam segment 8 with toothed blocks, the two first telescopic support members 612 retract downward respectively with unequal retraction lengths, so that the toothed block bottom mold 12 rotates downward to an enclosed state, and the toothed block end mold 14 can rotate downward under its own gravity. Then, the second support member 621 is installed to provide support for the toothed block end mold 14. When the second telescopic support assembly 62 uses the second telescopic support member 622, for continuous beam segments 8 without toothed blocks, the second telescopic support member 622 extends upward, driving the toothed block end mold 14 to rotate upward to a flattened state. For continuous beam segments 8 with toothed blocks, after the toothed block bottom mold 12 rotates downward to an enclosed state, the second telescopic support member 622 drives the toothed block end mold 14 to rotate downward to an enclosed state. The structure is simple, requires no disassembly or assembly, and is more convenient and faster to use.

[0052] See details Figure 17 In this embodiment, the third telescopic support assembly 63 includes a third telescopic support member 631, which is arranged along the transverse direction of the bridge. For a continuous beam segment 8 without toothed blocks, the third telescopic support member 631 extends, pushing the first toothed block side mold 13 upward to a flattened state. For a continuous beam segment 8 with toothed blocks, the third telescopic support member 631 retracts, causing the first toothed block side mold 13 to rotate downward to an enclosed state. The structure is simple and convenient to use.

[0053] In this embodiment, the fourth telescopic support assembly 64 includes a second top plate 641, a third support member 643 and a fourth telescopic support member 642. The fourth telescopic support member 642 is hinged to the telescopic adjustable back frame 6. The second top plate 641 is detachably connected to the fourth telescopic support member 642. The third support member 643 is a telescopic structure, or the third support member 643 is detachably connected to the adjustable back frame 6, or the third support member 643 is hinged to the adjustable back frame 6. See details Figure 10 When the second toothed block side mold 52 is in the flattened state, the second top plate 641 supports the second toothed block side mold 52. The second top plate 641 is driven to rotate and provide support through the fourth telescopic support member 642. At this time, the third support member 643 does not need to provide support for the second toothed block side mold 52 and can be disassembled, retracted, or rotated to an avoidance position; see details. Figure 14 When the second tooth block side mold 52 is in the enclosed state, the fourth telescopic support 642 is used to support the tooth block bottom mold 12, and the third support 643 is used to support the second tooth block side mold 52. Specifically, the second top plate 641 needs to be removed from the fourth telescopic support 642, and then the fourth telescopic support 642 needs to be rotated to a suitable angle and retracted to a suitable length, so as to cooperate with the first telescopic support 612 to provide reliable support for the tooth block bottom mold 12 in the enclosed state. At this time, the third support 643 needs to provide support for the second tooth block side mold 52 in the enclosed state. The third support 643 can be installed, or the third support 643 can be extended or rotated to the support position.

[0054] Furthermore, in this embodiment, the continuous beam inner mold also includes a fifth telescopic support assembly 65 supported on the top mold body 11. The fifth telescopic support assembly 65 includes a first support frame 651 mounted on the adjustable back frame 6 and a second support frame 652 detachably mounted on the first support frame 651. See details. Figure 10 For the continuous beam segment 8 without toothed blocks, the first support frame 651 can provide support for the top formwork body 11; see details. Figure 14 For the continuous beam segment 8 with toothed blocks, the adjustable back frame 6 needs to be lowered as a whole to avoid the toothed blocks. Then, the positions and angles of the templates corresponding to the toothed blocks (including the toothed block bottom mold 12, the first toothed block side mold 13, the toothed block end mold 14, and the second toothed block side mold 52) are adjusted into place. At the same time, a second support frame 652 needs to be installed on the first support frame 651 to increase the height of the fifth telescopic support assembly 65, so that the second support frame 652 can provide support for the top mold body 11. Preferably, the first support frame 615 is a metal support frame, such as stainless steel, which has high strength and is not easily damaged, while the second support frame 652 is a wooden support frame, which is lightweight and helps to reduce the difficulty of disassembly and transportation. It should be noted that although the second support frame 652 is a wooden support frame, the top mold body 11 is always in a horizontal state regardless of whether there are toothed blocks. Therefore, the second support frame 652 can be reused and does not need to be repeatedly reassembled.

[0055] Specifically, in the continuous beam inner mold of each embodiment of this application, each telescopic support member can be, for example, a support rod, a support tube, or a support column, and its specific telescopic structure is not limited. For example, it can be driven by a cylinder, a hydraulic cylinder, or a screw.

[0056] See details Figure 7 and Figure 8 In this embodiment, the first tooth block side mold 13 includes a first tooth block side mold mounting part 131 and a first tooth block side mold body 132. The first tooth block side mold mounting part 131 is slidably connected to the top mold body 11 in the transverse direction of the bridge, and the first tooth block side mold body 132 is hinged to the first tooth block side mold mounting part 131. This allows the first tooth block side mold body 132 to move in the transverse direction of the bridge and rotate in the longitudinal direction of the bridge, making it easy to adjust the position and angle in the transverse direction of the bridge, thereby adapting to the position and angle of the tooth blocks of the continuous beam segment 8. The second toothed block side mold 52 includes a second toothed block side mold mounting part 521 and a second toothed block side mold body 522. The second toothed block side mold mounting part 521 is slidably connected to the corner mold body 51 in the transverse direction of the bridge, and the second toothed block side mold body 522 is hinged to the second toothed block side mold mounting part 521. This allows the second toothed block side mold body 522 to move in the transverse direction of the bridge and rotate in the longitudinal direction of the bridge, making it easy to adjust the position and angle in the transverse direction of the bridge, so as to match the position and angle of the toothed blocks of the continuous beam segment 8. The toothed end mold 14 includes a toothed end mold mounting part 141 and a toothed end mold body 142. The toothed end mold mounting part 141 is slidably connected to the top mold body 11 along the longitudinal direction of the bridge. The toothed end mold body 142 is hinged to the toothed end mold mounting part 141, which can realize the movement of the toothed end mold body 142 along the longitudinal direction of the bridge and the rotation in the transverse direction of the bridge, so as to facilitate the adjustment of the position and angle in the transverse direction, thereby adapting to the position and angle of the toothed blocks of the continuous beam segment 8.

[0057] Furthermore, in this embodiment, the first tooth block side mold mounting part 131 is provided with a first waist-shaped hole (not shown in the figure) arranged along the transverse bridge direction and is detachably connected to the top mold body 11 by fasteners (not shown in the figure, such as bolts, screws, etc.) provided in the first waist-shaped hole; after removing the fasteners, the first tooth block side mold mounting part 131 can be moved in the transverse bridge direction, which is simple in structure and easy to adjust.

[0058] The second tooth block side mold mounting part 521 is provided with a second waist-shaped hole arranged along the transverse bridge direction and is detachably connected to the corner mold body 51 through fasteners provided in the second waist-shaped hole; The tooth block end mold mounting part 141 is provided with a third waist-shaped hole arranged along the longitudinal bridge direction and is detachably connected to the top mold body 11 through a fastener provided in the third waist-shaped hole. Correspondingly, the transverse bridge direction position adjustment method of the second tooth block side mold mounting part 521 and the longitudinal bridge direction position adjustment method of the tooth block end mold mounting part 141 are the same as those of the first tooth block side mold mounting part 131, and will not be described again.

[0059] Specifically, such as Figure 4 As shown, in this embodiment, the bottom mold 12 of the tooth block is provided with a first connecting template 3 along the transverse bridge towards the side opposite to the first tooth block side mold 13; the end mold 14 of the tooth block is provided with a second connecting template 4 along the transverse bridge towards the side opposite to the first tooth block side mold 13. When the tooth blocks at certain positions prevent the bottom mold 12, the first tooth block side mold 13, the end mold 14, and the second tooth block side mold 52 from forming a cavity for casting the tooth blocks, the first connecting template 3 and / or the second connecting template 4 can be further provided. The first connecting template 3 can be detachably installed on the bottom mold 12 of the tooth block using fasteners such as screws and bolts, or it can be an integral structure with the bottom mold 12 of the tooth block; the second connecting template 4 can be detachably installed on the end mold 14 of the tooth block using fasteners such as screws and bolts, or it can be an integral structure with the end mold 14 of the tooth block.

[0060] See details Figure 11 and Figure 15In this embodiment, a side mold 2 is provided below the corner mold 5, and a side mold back frame 7 is provided inside the side mold 2. The upper end of the side mold back frame 7 is hinged to an adjustable back frame 6. A demolding drive component such as a cylinder or hydraulic cylinder can be installed between the adjustable back frame 6 and the side mold back frame 7 for demolding. When demolding is required, the demolding drive component drives the side mold back frame 7 and the side mold 2 to rotate inward as a whole, thereby demolding the side mold 2. The structure is simple and has good reliability. Then the adjustable back frame 6 descends, and the inner mold completely separates from the continuous beam segment 8, moving along the longitudinal direction of the bridge.

[0061] The construction method of the continuous beam inner formwork in this embodiment is implemented using the aforementioned continuous beam inner formwork, including... When casting the continuous beam segment 8 without toothed blocks, adjust the toothed block bottom mold 12, the first toothed block side mold 13 and the toothed block end mold 14 to rotate to the flattened state and form the top mold 1 with the top mold body 11. Adjust the second toothed block side mold 52 to rotate to the flattened state and form the corner mold 5 with the corner mold body 51. Specifically: When the continuous beam segment 8 has no toothed blocks, each of the first telescopic support members 612 extends upward, driving the first top plate 611 to rotate and rise, causing the toothed block bottom mold 12 to rotate to a flattened state and providing support for the toothed block bottom mold 12. When the second telescopic support assembly 62 uses the second support member 621, the second support member 621 is disassembled, and the toothed block end mold 14 is rotated upward to a flattened state, allowing the toothed block bottom mold 12 to provide support for the toothed block end mold 14. When the second telescopic support assembly 62 uses the second telescopic support member 622, the second telescopic support member 622 extends upward, driving the toothed block end mold 14 to rotate upward to a flattened state. The third telescopic support member 631 extends, pushing the first toothed block side mold 13 to rotate upward to a flattened state. The second top plate 641 is driven to rotate by the fourth telescopic support member 642 and provides support for the second toothed block side mold 52. At this time, the third support member 643 does not need to provide support for the second toothed block side mold 52 and can be disassembled, retracted, or rotated to an avoidance position. The first support frame 651 provides support for the main body 11 of the top mold. After the casting is completed, the side mold 2 and the side mold back frame 7 are first moved inward, and then the inner mold is lowered as a whole to achieve demolding.

[0062] When casting the continuous beam segment 8 with toothed blocks, adjust the overlap position of the first toothed block side mold 13 and the toothed block end mold 14 with the top mold body 11; adjust the overlap position of the second toothed block side mold 52 with the corner mold body 51; adjust the toothed block bottom mold 12, the first toothed block side mold 13, the toothed block end mold 14 and the second toothed block side mold 52 to rotate to the enclosed state to form a cavity for casting toothed blocks.

[0063] Specifically: See Figure 16 and 18When the continuous beam segment 8 has toothed blocks, the adjustable back frame 6 lowers as a whole, and the two first telescopic support members 612 retract downwards by unequal lengths, causing the first top plate 611 to rotate downwards into an inclined state. The inclination angle matches the enclosed toothed block bottom mold 12, thus providing good support for the toothed block bottom mold 12. When the second telescopic support assembly 62 uses the second support member 621, the toothed block end mold 14 can rotate downwards under its own weight, and then the second support member 621 is installed to provide support for the toothed block end mold 14. When the second telescopic support assembly 62 uses the second telescopic support member 622, after the toothed block bottom mold 12 rotates downwards into an enclosed state, the second telescopic support member 622 drives the toothed block end mold 14 to rotate downwards into the enclosed state. See also Figure 17 The third telescopic support 631 then retracts, causing the first toothed block side mold 13 to rotate downwards into an enclosed state. (See also...) Figure 14 At this point, the second top plate 641 needs to be removed from the fourth telescopic support 642, and then the fourth telescopic support 642 needs to be rotated to a suitable angle and retracted to a suitable length to cooperate with the first telescopic support 612, providing reliable support for the toothed block bottom mold 12 in the enclosed state. At this time, the third support 643 needs to provide support for the second toothed block side mold 52 in the enclosed state. The third support 643 can be installed, or the third support 643 can be extended or rotated to the support position. At the same time, the second support frame 652 needs to be installed on the first support frame 651, thereby increasing the height of the fifth telescopic support assembly 65, so that the top mold body 11 can be supported by the second support frame 652. After the casting is completed, the side mold 2 and the side mold back frame 7 are first rolled inward, and then the inner mold is lowered as a whole, and the second support frame 652 is removed to achieve demolding.

[0064] Example 2 Figures 17 to 18 This invention illustrates another embodiment of the continuous beam inner mold of the present invention. The continuous beam inner mold of this embodiment is basically the same as that of Embodiment 1, except that: In this embodiment, the fifth telescopic support assembly 65 includes a plurality of fifth telescopic support members 653.

[0065] When the continuous beam segment 8 has no toothed blocks, multiple fifth telescopic supports 653 can provide support for the top formwork body 11. When the continuous beam segment 8 has toothed blocks, the fifth telescopic supports 653 need to extend, thereby increasing the height of the fifth support assembly 65 to continue providing support for the top formwork body 11. Before the inner formwork moves along the bridge direction, the fifth telescopic supports 653 need to retract downwards. Compared with Embodiment 1, there is no need to adjust the height of the fifth support assembly 65 by disassembling and assembling the second support frame 652, making it more convenient and faster to use.

[0066] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
