Technical Field

[0001] This utility model belongs to the field of hanging basket construction technology, specifically relating to an inner formwork for a continuous beam. Background Technology

[0002] The inner formwork of a continuous beam includes a top formwork, side formwork, upper corner formwork, and lower corner formwork. The top formwork is located at the top of the inner formwork, the side formwork is located on both sides of the inner formwork, and the upper and lower corner formwork are located at the intersection of the side formwork and the top formwork, and at the bottom end of the side formwork, respectively. Bridge tooth blocks are used to anchor the prestressed steel strands of the bridge and are usually made on the top and bottom slabs of the beam; their structure resembles a triangular block.

[0003] The top, side, and corner molds of conventional continuous beam internal formwork are assembled from steel molds of different specifications, which basically achieves the standardization of conventional hanging basket internal formwork. However, for bridge segments with toothed blocks, conventional internal formwork cannot be used for casting. When casting segments with upper toothed blocks, the steel molds and back frames corresponding to the upper toothed block positions need to be removed, and wooden molds need to be fabricated and assembled on-site. Temporary supports are added before casting. When casting segments with lower toothed blocks, the steel molds corresponding to the lower toothed block positions need to be removed, and wooden molds need to be fabricated and assembled on-site before casting.

After the back frame at the interference point was removed, there was a lack of necessary support system, which affected the stability of the overall structure. The temporarily added supports posed potential safety risks. Utility Model Content

[0028] like Figures 1 to 5 As shown, the continuous beam inner mold of this application embodiment includes a top mold 1, side molds 2, a support assembly 3, and one of corner molds 4 and toothed block molds 5; wherein, the side molds 2 are disposed on both sides of the top mold 1, and the corner molds 4 or toothed block molds 5 are detachably disposed at the junction of the side molds 2 and the top mold 1; the bottom of the top mold 1 is detachably provided with a top mold back frame 11, the inner side of the side mold 2 is detachably provided with a side mold back frame 21, a lateral telescopic drive assembly 6 is provided between the side mold back frame 21 and the top mold back frame 11, and the support assembly 3 is used to support the inner side of the corner mold 4 or toothed block mold 5; when the support assembly 3 supports the corner mold 4, it includes a first corner mold back frame 41 and a second corner mold back frame 42, the first corner mold back frame 41 being detachably connected to the first corner mold back frame 42. A portion 43 is connected to the bottom and top mold back frame 11. The second corner mold back frame 42 is detachably connected to the inner side of the second portion 44 of the corner mold. The first corner mold back frame 41 and the second corner mold back frame 42 are hinged to each other. Their hinge positions correspond to the positions close to the hinged positions of the first portion 43 and the second portion 44 of the corner mold. The first portion 43 of the corner mold is detachably connected to the top mold 1. When the support assembly 3 supports the toothed block mold 5, it includes a toothed block back frame 51 and a vertical telescopic drive assembly 52. ​​One end of the toothed block back frame 51 is detachably connected to the side mold back frame 21, and the other end is hinged to the top mold back frame 11. The two ends of the vertical telescopic drive assembly 52 are detachably connected to the bottom of the toothed block mold 5 and the top mold back frame 11, respectively.

[0029] The continuous beam inner formwork provided in this application uses steel molds for the corner molds 4 or toothed block molds 5 at the intersection of the top mold 1 and the side mold 2. This allows for a full steel mold design for the continuous beam inner formwork, resulting in better beam forming compared to existing technologies that partially use wooden molds. Furthermore, by converting the portion of the top mold back frame 11 that supports the corner molds 4 or toothed block molds 5 into a split support component 3, the support component 3 adopts different structural forms when supporting the corner molds 4 or toothed block molds 5. Compared to the existing technology where the back frame at the interference point on the top mold back frame 11 needs to be removed when casting the segment with toothed block molds 5, this greatly improves the overall stability and safety of the continuous beam inner formwork when casting the segment with toothed block molds 5, providing a more reliable guarantee for engineering construction. It eliminates the cumbersome steps of on-site fabrication of wooden molds and supports, effectively simplifying and optimizing the construction process, and thus significantly improving construction efficiency.

[0030] In this embodiment of the application, the corner mold 4 or toothed block mold 5 of the continuous beam inner mold can also be detachably disposed at the bottom end of the side mold 2. Obviously, by selectively providing the aforementioned steel corner mold 4 or toothed block mold 5 at the bottom end of the side mold 2, the applicability of the continuous beam inner mold is greatly improved.

[0031] In one embodiment, a first overlapping mold 8 is detachably provided at the bottom of the side mold 2. The first overlapping mold 8 is used to connect the side mold 2 and the corner mold 4 or the toothed block mold 5; or the first overlapping mold 8 is used to adjust the connection between the side mold 2 and the corner mold 4 or the toothed block mold 5. Specifically, the first overlapping mold 8 overlaps with the side mold 2 and the corner mold 4 or the toothed block mold 5 at the bottom of the side mold 2, which can be in the direction of bridge section height, i.e. Figures 1 to 4 The overlap length in the Y direction shown can be adjusted arbitrarily to adjust the connection between the side mold 2 and the corner mold 4 or the toothed block mold 5, which greatly improves the applicability of the continuous beam inner mold.

[0032] In one embodiment, the top mold 1 includes a first part 101 and a second part 103. A second overlapping mold 9 is provided between the first part 101 and the second part 103 of the top mold 1. The second overlapping mold 9 is used to adjust the connection between the first part 101 and the second part 103 of the top mold 1 and the corner mold 4 or the toothed block mold 5. In one embodiment, the top mold back frame 11 includes a support frame 12 and two sliding frames 14. The support frame 12 is used to anchor to the guide beam inside the hanging basket. The two sliding frames 14 are slidably disposed on the support frame 12 along the transverse direction of the beam. A transverse telescopic drive assembly 16 is provided on the support frame 12. The two ends of the transverse telescopic drive assembly 16 are respectively connected to the two sliding frames 14 to drive the sliding frames 14 along the transverse direction, i.e. Figures 1 to 4 The sliding direction is shown in the diagram. Specifically, the second overlapping mold 9 overlaps with the first part 101 and the second part 103 of the top mold 1. With the coordinated action of the telescopic drive of the two sliding frames 14 of the transverse telescopic drive assembly 16, the overlap length can be adjusted arbitrarily in the width direction of the bridge section, i.e., the transverse direction of the bridge. This allows for adjustment of the connection between the first part 101 and the second part 103 of the top mold 1 and the corner mold 4 or the toothed block mold 5, greatly improving the applicability of the continuous beam inner mold.

[0033] In one embodiment, the support frame 12 is provided with a mounting base 121, and the sliding frame 14 is provided with a first hinge seat 141. The middle part of the lateral telescopic drive assembly 16 is detachably connected to the mounting base 121, and the two ends of the lateral telescopic drive assembly 16 are respectively hinged to the first hinge seat 141. The two ends of the lateral telescopic drive assembly 6 are respectively hinged to the first hinge seat 141 and the second hinge seat 23 on the side mold back frame 21. Specifically, one end of the lateral telescopic drive assembly 16 and one end of the lateral telescopic drive assembly 6 are symmetrically hinged to the two ends of the same first hinge seat 141, and the two first hinge seats 141 are symmetrically arranged outside the lateral sides of the mounting base 121 used to fix the middle part of the lateral telescopic drive assembly 16. This greatly improves the structural compactness and stability reliability of the entire support system of the continuous beam inner mold.

[0034] like Figure 5 As shown, in one embodiment, the top of the support frame 12 is provided with a sliding rod 123 along the transverse bridge direction.

Clearly, the multiple sets of mounting holes 125 spaced apart on the sliding rod 123 on the support frame 12, and the waist-shaped holes 143 on the sliding frame 14 that mate with them, can greatly accommodate the installation and fixing of the first part 101 and the second part 103 of the top mold 1 during the adjustment of their overlapping positions with the second overlapping mold 9.

[0035] In one embodiment, the lateral telescopic drive assembly 6 and the vertical telescopic drive assembly 52 are both hydraulic cylinders, pneumatic cylinders, electric cylinders, and electric telescopic rods, and the lateral telescopic drive assembly 16 is a dual-output shaft linear drive mechanism. Clearly, the lateral telescopic drive assembly 6, the vertical telescopic drive assembly 52, and the lateral telescopic drive assembly 16 described above all possess the advantages of simple and compact structure, ease of installation, operation, and control, and stable and reliable operation.

[0036] The working principle of the continuous beam inner formwork in this embodiment is as follows:

[0037] When the cast segment has no toothed blocks, refer to Figure 1 At this point, the top mold back frame 11 works in conjunction with the first corner mold back frame 41 and the second corner mold back frame 42 to achieve the casting of toothless block segments. After casting is completed, refer to... Figure 2 First, the corner mold 4 at the bottom of the side mold 2 is removed. Then, with the help of the tension of the lateral telescopic drive component 6, the mold is rotated and demolded through the hinge point between the second corner mold back frame 42 and the first corner mold back frame 41. Then, with the help of the tension of the lateral telescopic drive component 16, the beam cross section is demolded laterally, that is, demolded in the transverse direction of the bridge. Then, the continuous beam inner mold is lowered as a whole and moved to the next segment.

[0038] When the cast-in-place segment has toothed blocks, refer to Figure 3 At this point, remove the corner mold 4, the first corner mold back frame 41, and the second corner mold back frame 42 at the junction of the side mold 2 and the top mold 1, and at the bottom of the side mold 2; install the toothed block mold 5, the toothed block back frame 51, and the vertical telescopic drive assembly 52 at the junction of the side mold 2 and the top mold 1, and at the bottom of the side mold 2, respectively, to achieve the casting of the toothed block segment. After casting is completed, refer to... Figure 4 First, the toothed block mold 5 at the bottom of the side mold 2 is removed. Then, with the help of the tension of the lateral telescopic drive component 6, the mold is rotated and demolded through the hinge point between the toothed block back frame 51 and the side mold back frame 21. Next, the height of the vertical telescopic drive component 52 is adjusted so that the toothed block mold 5 at the intersection of the side mold 2 and the top mold 1 is demolded. Finally, with the help of the tension of the lateral telescopic drive component 16, the transverse demolding of the beam cross section is achieved, that is, the transverse demolding of the bridge. Then, the inner mold is lowered as a whole and moved to the next segment.

[0039] As can be seen from the above embodiments, the continuous beam inner formwork involved in this application can adopt all-steel formwork templates. Compared with the existing technology that partially adopts wooden formwork, the beam forming effect is better. It eliminates the cumbersome steps of on-site wooden formwork and support, simplifies and optimizes the construction process, and significantly improves construction efficiency.

[0040] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
