Technical Field

[0001] This utility model belongs to the field of template support technology, and in particular relates to a foldable template support adjustment device for highway bridge cap beam construction. Background Technology

[0002] The cap beam is a key component of the substructure of a highway bridge. Located on top of the piers, it connects the pier columns on both sides laterally, directly supports the upper beam slab, and transfers the load to the pier columns and foundation. During the construction of the cap beam, a support device is needed to fix the pouring formwork, thereby preventing the formwork from tilting due to the injection of concrete during the construction of the cap beam.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing formwork support devices for highway bridge cap beam construction:

[0004] 1. The fixed connection between the fixed plate and the tilting rod results in the device taking up space when stored, making it inconvenient to add a flip connection to the device so that it can be flipped and folded for storage.

[0005] 2. The overall length of the tilting rod is fixed, and it cannot be adjusted according to the distance between the device and the template. It is inconvenient to add adjustment measures to the device so that the tilting rod can be adjusted according to the actual situation. Utility Model Content

[0007] The purpose and effectiveness of this utility model of a foldable formwork support and adjustment device for highway bridge cap beam construction are achieved through the following specific technical means:

[0008] A foldable formwork support and adjustment device for highway bridge cap beam construction includes a device body.

A vertical plate with front and rear through-holes is located at the front and rear ends of the bearing fixing plate. Semi-circular head plates with left and right through-holes are located on the left and right sides of the rear ends of the bearing fixing plate. A cylindrical rotating rod is installed between the semi-circular head plates via a fixing shaft. A semi-circular head block with left and right through-holes is located at the bottom rear end of the cylindrical rotating rod.

A threaded hole in the top rear end of the telescopic adjusting cylinder 8 is provided for easy assembly of the anti-detachment column 9 via threaded installation. The anti-detachment column 9 is installed inside the threaded hole of the telescopic adjusting cylinder 8 to prevent the telescopic adjusting cylinder 8 from detaching from the cylindrical flipping rod 3.

The top of the outer circumference of the telescopic support rod 10 has a front-to-back groove, which facilitates the insertion of the anti-rotation post 7 to prevent the telescopic support rod 10 from rotating. The front end of the telescopic support rod 10 is provided with a U-shaped plate that opens forward and extends vertically, which facilitates the insertion of the template for assembly. Both ends of the U-shaped plate of the telescopic support rod 10 are provided with semi-circular heads with left and right through holes, which facilitate the passage of the screw rod and the locking and fixing with a nut.

[0029] The specific usage and function of this embodiment are as follows:

[0030] In this utility model, when... Figure 1As shown, when using the device body 1, the operator first securely installs the bearing fixing plate 2 onto the construction platform using bolts. The construction platform is usually formed by erecting I-beams. Ensure that the U-shaped plate of the telescopic support rod 10 faces the cap beam construction template to provide a stable foundation for all subsequent actions. Use a special tool to fit onto the hexagonal prism at the front end of the folding rotating rod 4. Rotate the tool clockwise, and the folding rotating rod 4 will rotate smoothly on the vertical plate of the bearing fixing plate 2 via bearings. The rotation of the folding rotating rod 4 drives the folding moving block 5, which is threaded onto it, to move precisely forward along the axis of the folding rotating rod 4. The linear movement of the folding moving block 5 drives the semi-circular head at the rear end of the folding connecting plate 6 to move forward synchronously, causing the front end of the folding connecting plate 6 to flip upwards. The front end of the folding connecting plate 6 pushes the front end of the cylindrical flipping rod 3 to flip upwards. Thus, through the folding connecting plate 6, the horizontal displacement of the folding moving block 5 is converted into the rotational motion of the cylindrical flipping rod 3 around its fixed axis, thereby realizing the folding and unfolding of the cylindrical flipping rod 3. When the folding rotating rod 4 is rotated counterclockwise, the folding moving block 5 moves backwards. The cylindrical flipping rod 3 is folded and then folded back into place by folding the connecting plate 6 to make it fit tightly against the bearing fixing plate 2, achieving compact storage. This solves the problem of the fixed connection between the fixing plate and the tilting rod, which would otherwise occupy space when the device is stored. After the cylindrical flipping rod 3 is fully unfolded, the telescopic adjusting cylinder 8 is rotated clockwise with a tool to engage with the threaded telescopic support rod 10. Since the fixed anti-rotation post 7 is inserted into the slot of the telescopic support rod 10, it prevents the telescopic support rod 10 from rotating, forcing the telescopic support rod to... The support rod 10 can only move linearly in the axial direction within the telescopic adjustment cylinder 8, thus causing the telescopic support rod 10 to extend outward from inside the cylindrical flipping rod 3. This method solves the problem that the overall length of the tilting rod is fixed and cannot be adjusted according to the distance between the device and the template. The U-shaped plate of the telescopic support rod 10 is brought close to the back rib of the cap beam template, and the U-shaped plate at the front end of the telescopic support rod 10 aligns with the back rib of the cap beam template. Then, a screw is passed through the U-shaped plate and the pre-drilled hole in the template, and finally, a nut is used to lock it in place, forming a stable support connection, as shown in the diagram. Figure 6 As shown, the device body 1 is thus installed and used. When the telescopic adjustment cylinder 8 is rotated counterclockwise by a tool and engaged with the telescopic support rod 10 by thread, the telescopic support rod 10 retracts into the cylindrical flip rod 3. The assembly anti-detachment column 9 installed on the telescopic adjustment cylinder 8 always plays a key role. The lower end of the assembly anti-detachment column 9 is inserted into the anti-detachment ring groove of the cylindrical flip rod 3 to ensure that the telescopic adjustment cylinder 8 will not accidentally fall off the cylindrical flip rod 3 during the rotation adjustment process.

[0031] Example 2: The difference from Example 1 is that the regular hexagonal prism of the fixed anti-rotation column 7 can also be set as a regular heptagonal prism, so that the fixed anti-rotation column 7 can only be rotated by a special tool that cooperates with the regular heptagonal prism, thus preventing non-workers from rotating and disassembling the fixed anti-rotation column 7.

[0032] Example 3: The difference from Example 1 is that the regular hexagonal groove of the assembly anti-detachment column 9 can also be set as a regular heptagonal groove, so that the assembly anti-detachment column 9 can only be rotated by a special tool that cooperates with the regular heptagonal groove, thus preventing non-workers from rotating and disassembling the assembly anti-detachment column 9.
