Description

Technical Field

[0001] This utility model relates to the field of precast box girder side formwork structure technology, and in particular to a template combination structure applied to a hydraulic precast box girder side formwork device. Background Technology

[0002] In the field of bridge engineering, the use of precast component technology can significantly improve construction efficiency. By prefabricating components such as beams and piers in factories, and then transporting them to the construction site for direct assembly construction, this technology has multiple advantages over the traditional cast-in-place process: it eliminates time-consuming processes such as on-site formwork, concrete pouring, and component curing, while the modular production mode enables standardized operations and quality control.

[0003] Chinese Patent CN214026248U discloses a template assembly structure for use in a hydraulic precast box girder side formwork device. The structure includes a panel system, a support system, and an electromechanical-hydraulic system. The panel system is mounted on the support system, and the electromechanical-hydraulic system is connected to the support system. The support system is divided into several reference units of different lengths, and each reference unit has mounting holes for adjusting blocks. This allows the support system to be adjusted in a small range using the adjusting blocks, and also to be freely combined to different lengths through the splicing and assembly of the reference units. The length of the support system can be freely adjusted according to the length of the precast box girder. Furthermore, by setting back ribs within the panel system, the template is mounted on the support system via these back ribs. When different types of precast box girder templates need to be produced, only the panel system needs to be replaced, simplifying the replacement process, saving storage space for components, and reducing production costs.

[0004] However, the above technical solution has the following shortcomings: the support frame is the same as the support frame on a general side mold device. Since the support frame can be moved vertically by hydraulic drive, the bottom of the middle part of the support frame is in a floating state. As a result, during the mold closing process, the middle part of the side mold is prone to deformation or displacement due to excessive force, which affects the service life of the device. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a template assembly structure for use in hydraulic precast box girder side formwork devices, which can improve the support strength of the support frame and prevent the middle part of the side formwork from deforming or shifting due to excessive force.

[0007] Preferably, the pressure plate is provided with an insert block, and the support frame is provided with a positioning groove for the insert block to be inserted.

[0008] Preferably, the anti-detachment component includes a rod with a handle and a threaded portion, and a threaded ring threadedly connected to the rod.

[0009] Preferably, the support frame is provided with multiple connecting beams, the connecting beams are provided with inclined support plates, and the inclined support plates are provided with templates.

[0010] Preferably, the connecting beam is provided with multiple symmetrically distributed spreader beams, and a connecting pin is provided through the spreader beams.

[0011] Preferably, a drive mechanism is provided below the support frame. The drive mechanism includes a vehicle body, a mounting seat on the vehicle body, two first hydraulic cylinders vertically distributed on the mounting seat, and a connecting plate driven and connected to the first hydraulic cylinders; a circular groove for the connecting plate to be embedded is provided on the connecting beam.

[0012] Preferably, a plurality of fixing bolts arranged in a circular array are provided through the connecting plate, and the fixing bolts and the connecting plate abut against each other and are threadedly connected to the connecting beam.

[0013] Preferably, the drive mechanism further includes a second hydraulic cylinder mounted on the vehicle body and a movable seat driven and connected to the second hydraulic cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects:

[0015] This utility model, through its supporting mechanism, can distribute the lateral pressure of the concrete on the support frame, preventing the side formwork from deforming or shifting due to excessive force, thereby ensuring the quality of concrete pouring, extending the service life of the structure, and improving the ease of use of the supporting mechanism with the anti-detachment component.

[0021] Example 1

[0022] like Figures 1-4 As shown in the figure, the template assembly structure proposed in this embodiment for use on the side formwork device of hydraulic precast box girder includes a support frame 1 and a support mechanism.

[0023] The support mechanism includes a fixed base 2, a fixed cylinder 4 disposed inside the fixed base 2, a spring 5 disposed inside the fixed cylinder 4, a support column 6 disposed on the spring 5 and slidably connected to the fixed cylinder 4, a pressure plate 7 disposed on the support column 6, four guide blocks 8 arranged in a ring array on the support column 6, a gripping plate 3 disposed at the bottom of the fixed base 2, and an anti-detachment component disposed on the fixed base 2. The fixed cylinder 4 is provided with four sliding grooves for the guide blocks 8 to slide. The bottom of the support bracket 1 is inserted into the fixed base 2 and slidably connected. The pressure plate 7 is provided with an insert block 9, and the support bracket 1 is provided with a positioning groove for the insert block 9 to be embedded. The sliding grooves and the guide blocks 8 guide the movement of the support column 6, thereby preventing the spring 5 from bending or twisting and extending the service life of the spring 5.

[0024] The anti-detachment component includes a rod 10 with a handle and a threaded portion, and a threaded ring 11 threadedly connected to the rod 10.

[0025] In this embodiment, when the mold is closed, the fixed seat 2 is sleeved on the bottom of the support frame 1 in the middle of the side mold that is not in contact with the ground. This allows the pressure plate 7 to provide auxiliary support to the support frame 1 under the support force of the spring 5 and the support column 6. When concrete is poured, it bears the lateral pressure of the concrete, preventing the side mold from deforming or shifting due to excessive force, thereby ensuring the quality of concrete pouring and extending the service life of the structure. By inserting the rod 10 through the support frame 1 and screwing the threaded ring 11 onto the threaded part, the fixed seat 2 will not detach from the bottom of the support frame 1 during the process of mold closing, lifting, and translation, improving the convenience of use of the support mechanism and having good practicality.

[0026] Example 2

[0027] like Figure 1 As shown in the figure, this embodiment proposes a template assembly structure for use on a hydraulic precast box girder side formwork device. Compared with the first embodiment, in this embodiment, the support frame 1 is provided with multiple connecting beams 12, the connecting beams 12 are provided with inclined support plates 13, the inclined support plates 13 are provided with templates 14, the connecting beams 12 are provided with multiple symmetrically distributed spreader beams 15, and the spreader beams 15 are provided with connecting pins 16. The connecting beams 12 are used to build the overall frame of the side formwork, the inclined support plates 13 are used to fix the inclined surface of the templates 14, the spreader beams 15 are used to increase the structural strength of the side formwork, and the connecting pins 16 are used to improve the stability of the spreader beams 12, further improving the stability of the side formwork.

[0028] Example 3

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, this embodiment proposes a template assembly structure for use on the side formwork device of a hydraulic precast box girder. Compared with Embodiment 1, in this embodiment, a drive mechanism is provided below the support frame 1. The drive mechanism includes a vehicle body 17, a mounting seat 18 provided on the vehicle body 17, two first hydraulic cylinders 19 vertically distributed on the mounting seat 18, and a connecting plate 20 drivenly connected to the first hydraulic cylinders 19. A circular groove for the connecting plate 20 to be embedded is provided on the connecting beam 12. A plurality of fixing bolts 21 arranged in a ring array are provided through the connecting plate 20. The fixing bolts 21 and the connecting plate 20 abut against each other and are threadedly connected to the connecting beam 12.

[0030] The drive mechanism also includes a second hydraulic cylinder 22 mounted on the vehicle body 17 and a movable seat 23 driven and connected to the second hydraulic cylinder 22. The mounting seat 18 is mounted on the movable seat 23. The movable seat 23 is provided with four linearly arrayed and rotatably connected rollers 24. When the second hydraulic cylinder 22 drives the movable seat 23 to move to move the side mold, the rollers 24 can reduce energy consumption and wear by reducing the friction of the movable seat 23 without affecting stability.

[0031] In this embodiment, the entire side formwork device is driven to move vertically and horizontally by the first hydraulic cylinder 19 and the second hydraulic cylinder 22 to precisely control the movement and positioning of the side formwork, ensuring that the side formwork is in the correct position during the construction of the precast box girder. At the same time, it prevents the side formwork from being displaced or deformed due to the impact and vibration of the concrete, thus ensuring the quality of concrete pouring and the external dimensions of the box girder. The first hydraulic cylinder 19 and the side formwork can be quickly and stably fixed and installed by the fixed bolts 21, the connecting plate 20 with multiple countersunk holes, and the circular groove on the connecting beam 12.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
