Description

Technical Field

[0001] This utility model relates to the field of template support technology, and in particular to a concrete inclined template support for flood control dikes. Background Technology

[0002] In the field of flood control engineering, the concrete slope of a flood control dike is the core functional structure of the dike, mainly consisting of the upstream slope and the downstream slope. Through specific slope design, it achieves key functions such as water blocking, wave resistance, and drainage, and is widely used in river embankments, reservoir dams, and coastal breakwaters. The formwork support for the concrete slope of a flood control dike is the core supporting equipment for the casting and shaping of the dike's slope structure (such as the upstream and downstream slopes). By fixing the formwork position and bearing the lateral pressure of the concrete and construction loads, it ensures that the designed slope (usually 1:1.5-1:3) and structural dimensions are maintained during the concrete casting process. It is a key construction component ensuring the flood control dike's impermeability and erosion resistance, and is widely used in the construction and reinforcement of flood control projects such as river embankments and reservoir dams.

[0003] However, most of the existing formwork support members on the inclined plane are of fixed length. When constructing on different inclined planes, support members of different lengths need to be customized. This makes it inconvenient to adjust the length of the support members according to the construction inclined plane, resulting in high costs and inconvenience in use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a concrete inclined formwork support for flood control dikes to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a concrete slope formwork support for a flood control dike, including a molded panel laid on the slope of the flood control dike. A swivel fastener is fixedly installed at one end of the molded panel for connection. A telescopic support rod is fixedly installed at one end of the swivel fastener for support. A fixing rod is provided at the bottom of the telescopic support rod for support and guidance. A locking block is fixedly installed at the bottom of the telescopic support rod for limiting and fixing it. A locking disc is rotatably connected inside the locking block for engagement and fixing. A high-strength ring plate is provided on one side of the locking disc, located inside the fixing rod. A sealed airbag sleeve containing internal gas is fixedly installed at the bottom of the locking disc. A base for supporting and fixing the fixing rod is fixedly installed at the bottom of the sealed airbag sleeve. A diagonal brace for supporting the molded panel is fixedly installed at one end of the base.

[0006] Preferably, in any of the above embodiments, the molded panel and the swivel fastener are fixedly installed by bolts, and the top end of the telescopic support rod is provided with a connecting block adapted to the swivel fastener, and the connecting block is fixedly installed by bolts and the swivel fastener.

[0007] The above technical solution is adopted as follows: the molded panel (Q235 steel plate) serves as the molding reference for concrete pouring. It is rigidly connected to the swivel fastener (cast steel material, galvanized surface) by M12 stainless steel bolts. The bolts pass through the connection holes of the panel and the fastener to ensure the connection strength and prevent the panel from shifting during pouring. The connecting block at the top of the telescopic support rod (U-shaped structure adapted to the fastener) is fixed to the swivel fastener by bolts of the same specification. This allows the support rod to be adjusted at a certain angle around the fastener to adapt to different slopes of the flood control dike. It ensures that the axis of the support rod is consistent with the normal direction of the panel and evenly bears the lateral pressure of the concrete.

[0008] Preferably, the bottom of the fixing rod is provided with a threaded groove for fixing the base, the inside of the fixing rod is provided with a sliding groove for limiting and guiding the locking block, and one side of the sliding groove is provided with a scale mark to indicate the position of the locking block.

[0009] The above technical solution is adopted: the threaded groove at the bottom of the fixing rod (seamless steel pipe) is threadedly connected to the base, and the base is fixed by the thread preload to prevent the fixing rod from shaking. The internal slide groove and the boss of the locking block are fitted with a clearance to provide axial guidance for the locking block, restricting it to slide only along the slide groove. This ensures that the telescopic support rod moves along the axis of the fixing rod when it is adjusted. The scale markings on one side of the slide groove clearly show the position of the locking block, making it easy for operators to quickly read the extension length of the telescopic support rod without the need for additional measuring tools.

[0010] Preferably, in any of the above embodiments, the locking block is made of stainless steel, and both ends of the locking block are provided with bosses to limit its movement, and the bottom of the locking block is provided with a rotating groove to accommodate the locking disc.

[0011] The above technical solution is adopted: the bosses at both ends of the locking block (made of stainless steel) are embedded in the grooves of the fixing rod to form a bidirectional limit, preventing the locking block from rotating radially around the fixing rod, ensuring that the locking disc and the high-strength ring plate are precisely engaged. The bottom rotating groove is rotatably connected to the locking disc through a bearing, providing stable support for the locking disc, while allowing it to rotate around the axis of the locking block, realizing the action conversion of "adjustment-engagement-fixation". The magnetic properties of the stainless steel material can attract the magnet block of the locking disc, ensuring that the position of the locking disc is stable in the non-adjustment state and avoiding accidental loosening.

[0012] Preferably, in any of the above embodiments, the locking disc includes a magnet block for adsorption connection and a support plate for limiting the position of the fixing rod. The magnet block is adsorbed inside the locking block. One end of the magnet block is fixedly installed with a support plate rotatably connected inside the locking block. Both ends of the support plate are provided with fixing blocks that engage with high-strength ring pieces. The high-strength ring pieces are fixedly connected inside the fixing rod.

[0013] The above technical solution involves: a magnet (made of neodymium iron boron) adsorbing inside a locking block, initially fixing the support plate with magnetic force to prevent free rotation; when the fixing blocks at both ends of the support plate engage with high-strength ring plates (made of spring steel with teeth that match the fixing blocks), a mechanical locking structure is formed, restricting the axial movement of the telescopic support rod; when adjusting the length of the telescopic support rod, an external force is applied to rotate the support plate, causing the fixing blocks to disengage from the high-strength ring plates, and the magnets rotate synchronously with the support plate (the magnetic attraction force remains unchanged); after adjustment, the support plate is rotated in the opposite direction, and the fixing blocks re-engage with the ring plates, thus locking the position of the telescopic support rod without the need for additional fasteners.

[0014] Preferably, in any of the above embodiments, the sealing airbag sleeve is fixedly installed at the bottom of the support plate, the sealing airbag sleeve is located inside the fixing rod, the bottom of the sealing airbag sleeve and the base are fixedly installed, and the base is threadedly connected to the bottom of the fixing rod.

[0015] The above technical solution employs a pre-filled, compressed air-filled airbag sleeve (made of butyl rubber) which is fixedly installed between the bottom of the support plate and the base, inside the fixed rod. In the non-adjustable state, the airbag sleeve generates an upward supporting force through air pressure, assisting in supporting the telescopic support rod, offsetting part of the concrete load, reducing the biting pressure on the locking disc, and extending the service life of the locking structure. When adjusting the telescopic support rod, the support plate moves downwards or upwards, compressing or stretching the airbag sleeve. The internal air pressure of the airbag sleeve changes synchronously, always maintaining elastic support for the support plate and avoiding rigid impacts during adjustment.

[0016] Preferably, in any of the above embodiments, the diagonal brace includes a diagonal brace fixing rod that supports the molded panel and an insert plate that engages and fixes it. The diagonal brace fixing rod is inserted into the interior of the base, and the insert plate that moves inside the base is engaged inside the diagonal brace fixing rod.

[0017] The above technical solution is adopted: the diagonal brace fixing rod is inserted into the slot of the base, and its top end is connected to the molded panel by bolts to form a triangular support structure. Together with the telescopic support rod, it bears the overturning moment of the panel and improves the overall stability of the template support. The insert plate inside the diagonal brace fixing rod is engaged with the slot inside the base by spring. The position of the insert plate can be adjusted according to the insertion depth of the diagonal brace fixing rod. The engagement between the insert plate and the slot enhances the connection strength between the diagonal brace fixing rod and the base and prevents the diagonal brace rod from loosening.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. A fixed rod for support and fixation and a telescopic support rod for telescopic adjustment are set at one end of the template support. The position of the telescopic support rod inside the fixed rod can be adjusted according to the needs of the template support. The length of the support rod of the template support can be adjusted. The position of the telescopic support rod is positioned by the locking block and locking plate at the bottom of the telescopic support rod and the high-strength replacement plate inside the fixed rod, and the length of the support rod is fixed, thereby improving the stability of the template support.

[0019] 2. A sealed airbag sleeve containing internal gas is installed at the bottom of the locking plate, so that the inside of the sealed airbag sleeve is under high pressure. The high-pressure sealed airbag sleeve provides auxiliary support for the telescopic support rod, further enhancing the stability of the telescopic support rod after adjustment and enhancing the overall support strength of the support rod.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0023] like Figure 1-4As shown in the figure, a concrete slope formwork support for a flood control dike according to an embodiment of the present invention includes a molded panel 1 laid on the slope of the flood control dike. A rotating fastener 2 is fixedly installed at one end of the molded panel 1 for connection. A telescopic support rod 3 for support is fixedly installed at one end of the rotating fastener 2. A fixed rod 4 for support and guidance is provided at the bottom of the telescopic support rod 3. A locking block 5 for limiting and fixing is fixedly installed at the bottom of the telescopic support rod 3. A locking disc 6 for engaging and fixing is rotatably connected inside the locking block 5. A high-strength ring plate 7 located inside the fixed rod 4 is provided on one side of the locking disc 6. A sealing airbag sleeve 8 for storing gas is fixedly installed at the bottom of the locking disc 6. A base 9 for supporting and fixing the fixed rod 4 is fixedly installed at the bottom of the sealing airbag sleeve 8. A diagonal brace 10 for supporting the molded panel 1 is fixedly installed at one end of the base 9.

[0024] Preferably, in any of the above solutions, the molded panel 1 and the swivel fastener 2 are fixedly installed by bolts, and the top of the telescopic support rod 3 is provided with a connecting block that is compatible with the swivel fastener 2. The connecting block is fixedly installed by bolts and the swivel fastener 2.

[0025] The above technical solution is adopted as follows: the molded panel 1 (Q235 steel plate) serves as the molding reference for concrete pouring. It is rigidly connected to the swivel fastener 2 (cast steel material, galvanized surface) by M12 stainless steel bolts. The bolts pass through the connection holes between the panel and the fastener to ensure the connection strength and prevent the panel from shifting during pouring. The connecting block (U-shaped structure adapted to the fastener) at the top of the telescopic support rod 3 is fixed to the swivel fastener by bolts of the same specification. This allows the support rod to be adjusted at a certain angle around the fastener to adapt to different slopes of the flood control dike. It ensures that the axis of the support rod is consistent with the normal direction of the panel and evenly bears the lateral pressure of the concrete.

[0026] Preferably, the bottom of the fixing rod 4 is provided with a threaded groove for fixing the base 9, and the inside of the fixing rod 4 is provided with a sliding groove for limiting and guiding the locking block 5. A scale mark is provided on one side of the sliding groove to indicate the position of the locking block 5.

[0027] The above technical solution is adopted: the threaded groove at the bottom of the fixing rod 4 (seamless steel pipe) is threadedly connected to the base 9, and the base is fixed by the thread preload to prevent the fixing rod from shaking. The internal slide groove and the boss 11 of the locking block 5 are clearance-fitted to provide axial guidance for the locking block, restricting it to slide only along the slide groove, ensuring that the telescopic support rod 3 moves along the axis of the fixing rod when adjusted. The scale markings on one side of the slide groove intuitively show the position of the locking block, making it easy for operators to quickly read the extension length of the telescopic support rod without the need for additional measuring tools.

[0028] Preferably, the locking block 5 is made of stainless iron, and both ends of the locking block 5 are provided with bosses 11 to limit its movement. The bottom of the locking block 5 is provided with a rotating groove to accommodate the locking disc 6.

[0029] The above technical solution is adopted: the bosses 11 at both ends of the locking block 5 (stainless iron material) are embedded in the sliding grooves of the fixing rod 4 to form a bidirectional limit, preventing the locking block from rotating radially around the fixing rod, ensuring that the locking disc 6 and the high-strength ring plate 7 are precisely engaged. The bottom rotating groove is rotatably connected to the locking disc 6 through the bearing, providing stable support for the locking disc, while allowing it to rotate around the axis of the locking block, realizing the action conversion of "adjustment-engagement-fixation". The magnetic properties of the stainless iron material can attract the magnet block 61 of the locking disc 6, ensuring that the position of the locking disc is stable in the non-adjustment state and avoiding accidental loosening.

[0030] Preferably, in any of the above embodiments, the locking disc 6 includes a magnet block 61 for adsorption connection and a support plate 62 for limiting the position of the fixing rod 4. The magnet block 61 is adsorbed inside the locking block 5. One end of the magnet block 61 is fixedly installed with the support plate 62, which is rotatably connected inside the locking block 5. Both ends of the support plate 62 are provided with fixing blocks that engage with the high-strength ring piece 7. The high-strength ring piece 7 is fixedly connected inside the fixing rod 4.

[0031] Using the above technical solution: The magnet 61 (made of neodymium iron boron) is attracted to the inside of the locking block 5, and the support plate 62 is initially fixed by magnetic force to prevent it from rotating freely. When the fixing blocks at both ends of the support plate engage with the high-strength ring plate 7 (made of spring steel, with teeth that match the fixing blocks), a mechanical locking structure is formed, which restricts the axial movement of the telescopic support rod 3. When adjusting the length of the telescopic support rod, an external force is applied to rotate the support plate, causing the fixing blocks to disengage from the high-strength ring plate. The magnet rotates synchronously with the support plate (the magnetic attraction force remains unchanged). After the adjustment is in place, the support plate is rotated in the opposite direction, and the fixing blocks re-engage with the ring plate, thereby locking the position of the telescopic support rod without the need for additional fasteners.

[0032] Preferably, in any of the above solutions, the sealing airbag sleeve 8 is fixedly installed at the bottom of the support plate 62, the sealing airbag sleeve 8 is located inside the fixing rod 4, the bottom of the sealing airbag sleeve 8 and the base 9 are fixedly installed, and the base 9 is threadedly connected to the bottom of the fixing rod 4.

[0033] The above technical solution employs the following: A pre-filled airbag sleeve 8 (made of butyl rubber) is fixedly installed between the bottom of the support plate 62 and the base 9, located inside the fixing rod 4. In the non-adjustable state, the airbag sleeve generates an upward supporting force through air pressure, assisting in supporting the telescopic support rod 3, offsetting part of the concrete load, reducing the biting pressure of the locking disc 6, and extending the service life of the locking structure. When adjusting the telescopic support rod, the support plate moves downward or upward, squeezing or stretching the airbag sleeve. The air pressure inside the airbag sleeve changes synchronously, always maintaining elastic support for the support plate and avoiding rigid impact during adjustment.

[0034] Preferably, in any of the above embodiments, the diagonal brace 10 includes a diagonal brace fixing rod 101 that supports the molded panel 1 and an insert plate 102 that engages and fixes it. The diagonal brace fixing rod 101 is inserted into the interior of the base 9, and the insert plate 102 that moves inside the base 9 is engaged inside the diagonal brace fixing rod 101.

[0035] The above technical solution is adopted: the diagonal bracing rod 101 is inserted into the slot of the base 9, and its top end is connected to the molding panel 1 by bolts to form a triangular support structure. Together with the telescopic support rod 3, it bears the overturning moment of the panel and improves the overall stability of the template support. The insert plate 102 inside the diagonal bracing rod is engaged with the slot inside the base by spring. The position of the insert plate can be adjusted according to the insertion depth of the diagonal bracing rod. The engagement between the insert plate and the slot enhances the connection strength between the diagonal bracing rod and the base and prevents the diagonal bracing rod from loosening.

[0036] The working principle of this utility model for a concrete inclined formwork support for a flood control dike is as follows: First, lay the molded panel 1 on the slope of the flood control dike and fix it to the swivel fastener 2 with bolts. Then, fix the top connecting block of the telescopic support rod 3 to the swivel fastener 2 with bolts. Adjust the angle of the support rod according to the slope of the dike. Then, screw the base 9 to fix it through the threaded groove at the bottom of the fixing rod 4. Push the telescopic support rod 3 to drive the locking block 5 to slide along the inner slide groove of the fixing rod 4. Adjust the extension length of the support rod according to the scale markings on the slide groove. During this process, the protrusions 11 at both ends of the locking block 5 ensure the stability of the sliding direction. After the adjustment is in place, rotate the support plate of the locking disc 6 inside the locking block 5. 62, so that the fixing blocks at both ends engage with the high-strength ring plate 7 inside the fixing rod 4, the magnet block 61 attracts the locking block 5 to keep it locked and stable, and at the same time the bottom sealing airbag sleeve 8 (pre-filled with high-pressure gas) generates an upward supporting force to assist in supporting the telescopic support rod 3. Finally, the diagonal bracing rod 101 of the diagonal bracing rod 10 is inserted into the base 9, the insertion plate 102 is adjusted to the locking position in the base, and the top end is connected to the forming panel 1 to form a triangular support, which works with the telescopic support rod 3 to bear the side pressure of concrete and the overturning moment, ensuring that the forming panel 1 maintains the designed slope stably during the pouring process.
