The bottom of the formwork is far from the force point, the bending moment is large, and the vibration impact force is more significant. Long-term use will cause support deformation and affect its service life.

Then, rotate the support plate to adjust the support angle as needed, so that the front surface of the support plate fits the outer surface of the template. Then, fix the support plate and the template with bolts.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, the device is provided with a support plate and an extrusion structure, and the support plate is rotated to adjust the support angle. At the same time, rotating the support plate will drive the first bevel gear to rotate and drive the second bevel gear to rotate through the linkage rod to rotate the threaded rod, and then drive the extrusion plate to move toward the middle along the third damping liquid chamber through the transmission plate, so that the damping fluid in the third damping liquid chamber moves into the second damping liquid chamber and pushes the movable plate outward, thereby compressing the spring and giving the lower support rod an upward thrust to prevent the support plate from rotating outward, increasing the gravity of the concrete above, and causing the first support structure to deform. While adjusting the support angle and increasing applicability, the first support structure is made more stable.

[0017] 2. In the present invention, the device adjusts the support height as needed by setting an extension plate to avoid damage to the support assembly due to excessive bending moment caused by too low support. In addition, when the extension plate is pulled upward, the pull rope is gradually tightened and pulls the inner pull plate outward, and the outer pull plate is moved outward through the connecting rod to compress the outer pull plate, thereby causing the damping fluid in the third damping fluid chamber to move into the second damping fluid chamber to push the movable plate outward and compress the spring, giving an upward thrust to the lower push rod, avoiding the template being too high and too much concrete poured inside, so that the lateral force center of the concrete on the template is too high, resulting in excessive bending moment at the bottom of the template, which causes deformation of the first support structure. While adjusting the support height and increasing applicability, the first support structure is made more stable.

[0018] 3. In the present invention, the device sets a first supporting structure and a second supporting structure. When subjected to a vibration impact force, the top end of the rod continuously and rapidly moves back and forth in the first damping liquid chamber, and energy is dissipated and shock-absorbing is performed by heating the damping liquid to ensure the stability of the support. At the same time, the rapidly moving rod will push the damping liquid in the first damping liquid chamber through the third damping liquid chamber into the second damping liquid chamber, and then push the movable plate upward to give the first supporting structure an upward thrust, thereby avoiding the deformation of the first supporting structure that cannot be restored due to excessive vibration impact force. When the poured concrete is subjected to vibration impact, shock absorption and energy dissipation are performed, and at the same time, the first supporting structure is made more stable.

[0021] Unless explicitly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood as including the stated elements or components but not excluding other elements or components.

[0022] Reference Figure 1 -As shown in FIG9 , this embodiment provides a technical solution: A seismic support device for a casting formwork for construction, comprising a formwork 1 and a support assembly 2 arranged outside the formwork 1 for support, the support assembly 2 comprising a base 21, a backing plate 22 on the front side of the top surface of the base 21, and an extension plate 23 arranged in a sliding connection with the backing plate 22, a first support structure 24 is arranged in the middle of the top surface of the base 21 and on both left and right sides, and a second support structure 25 is arranged below the first support structures 24 on both left and right sides, and the first support structure 24 cooperates with the second support structure 25 to support the backing plate 22 and the extension plate 23, thereby improving the stability of the support; The first supporting structure 24 includes an upper support rod 242 whose top end is hinged to the rear side wall of the support plate 22 by the top, and a lower support rod 241 whose bottom end is hinged to the top surface of the base 21. A limiting cavity 2422 is provided at the bottom end of the upper support rod 242, and a limiting block 2413 adapted to the limiting cavity 2422 is fixed to the top of the lower support rod 241. By setting the limiting cavity 2422 and the limiting block 2413, the lower support rod 241 and the upper support rod 242 can slide against each other, thereby ensuring The proof plate 22 rotates, and the upper top surface of the limit block 2413 is fixedly connected with the insertion rod 2411. A first damping liquid chamber 2421 is provided above the limit chamber 2422 in the upper push rod 242. The top end of the insertion rod 2411 extends into the first damping liquid chamber 2421. When the concrete is poured and vibrates, the top end of the insertion rod 2411 continuously moves back and forth in the first damping liquid chamber 2421, and the heat of the damping liquid is used to dissipate energy and reduce vibration, so as to ensure the stability of the support; The second supporting structure 25 includes an upper supporting rod 252 connected to the top of the lower supporting rod 241 and a lower supporting rod 251 connected to the bottom of the upper supporting rod 252 by sliding. The bottom of the upper supporting rod 252 is symmetrically fixed with a sliding rod 254, and a movable plate 253 is slidably connected to the sliding rod 254. The outer wall of the sliding rod 254 is located above the movable plate 253 and is sleeved with a spring 255. The inner cavity of the lower supporting rod 251 is located below the movable plate 253 and is a second damping liquid cavity 2511. The cavity located above the movable plate 253 is the movable plate cavity 2512. The upper support rod 252 and the lower support rod 241 are fixed by bolts during installation. When the support plate 22 rotates backward to adjust the angle, the damping fluid in the second damping fluid cavity 2511 will push the movable plate 253 upward to compress the spring 255, and then provide an upward thrust for the upper support rod 252 to avoid bending deformation of the middle part of the first support structure 24 due to the increase of the concrete gravity above when the support plate 22 rotates backward. A fixed cylinder 26 is provided on the front side of the top surface of the base 21, and an extrusion structure 28 is provided at the left and right ends of the fixed cylinder 26. A pull plate cavity 262 is provided in the middle of the fixed cylinder 26, and a third damping liquid cavity 261 is provided between the extrusion structure 28 and the pull plate cavity 262. The third damping liquid cavity 261 is connected to the first damping liquid cavity 2421 through a first connecting pipe 256, and the third damping liquid cavity 261 is connected to the second damping liquid cavity 2511 through a second connecting pipe 27. When the pouring of concrete encounters a vibration impact force, the insertion rod 2411 will push the damping liquid in the first damping liquid cavity 2421 through the third damping liquid cavity 261 into the second damping liquid cavity 2511, and then push the movable plate 253 upward to give the first supporting structure 24 an upward thrust, so as to avoid the first supporting structure 24 from being deformed and unable to recover due to excessive vibration impact force.

[0023] In addition, if Figure 1 , Figure 2 As shown in Figure 8, an extension plate groove 221 is provided in the support plate 22, and the extension plate 23 is arranged in the extension plate groove 221 and the two are slidably connected. The extension plate 23 and the right side surface of the support plate 22 are located in the same plane, and the front and rear side walls of the support plate 22 are fixed with a first bevel gear 222 near the top, and a linkage rod 223 is arranged on the right side of the first bevel gear 222. The left and right ends of the linkage rod 223 are coaxially fixed with bevel gears and the left end bevel gear is meshed with the first bevel gear 222. When the support plate 22 rotates, the linkage rod 223 is driven to rotate by the first bevel gear 222. The first bevel gear 222 and the linkage rod 223 are both arranged in the base 21, and the top surface of the base 21 is provided with a plurality of support rod grooves 211 corresponding to the position and size of the plurality of second support structures 25 at the rear end, and the top surface of the base 21 is provided with a mounting groove 212 at the front end. The bottom ends of the left and right side walls of the support plate 22 are rotatably connected with the left and right side walls of the mounting groove 212, and the left and right ends of the fixing cylinder 26 are fixed in the mounting groove 212 near the front end.

[0024] Furthermore, if Figure 5 As shown in Figure 7, pull ropes 231 are symmetrically provided on the bottom surface of the extension plate 23, and connecting rods 232 are provided on the left and right sides of the pull plate cavity 262. Pull plates 233 are fixed at both ends of the left and right ends of the connecting rod 232. The outer pull plate 233 is arranged in the third damping liquid cavity 261 on the same side and the sizes of the two are matched. One end of the pull rope 231 passes through the bottom surface of the extension plate groove 221 and the wall of the fixed cylinder 26 in sequence and is fixed to the outer surface of the corresponding pull plate 233 on the same side, and the other end is fixed to the bottom surface of the extension plate 23. When the extension plate 23 is pulled upward, the pull rope 231 will drive the connecting rod 232 on the same side to move outward, thereby causing the outer pull plate 233 to slide outward to squeeze the damping liquid in the third damping liquid cavity 261 into the second damping liquid cavity 2511. It should be noted that when the extension plate 23 is adjusted, the angle of the abutment plate 22 is fixed, and at this time the extrusion structure 28 will not be squeezed by the pull plate 233.

[0025] In addition, if Figure 3-Figure 4 As shown, a sealing plate 2412 is coaxially fixed to the bottom end of the side wall of the insertion rod 2411, and a protective cavity is provided in the upper support rod 242 between the limiting cavity 2422 and the first damping liquid cavity 2421. The sealing plate 2412 is provided to prevent the damping liquid from leaking directly when it is subjected to the impact force of squeezing or vibration. The sealing plate 2412 has the same size as the protective cavity. The top end of the insertion rod 2411 is located in the first damping liquid cavity 2421 and the size of the top end of the insertion rod 2411 is smaller than the size of the first damping liquid cavity 2421 and larger than the rod size of the insertion rod 2411, thereby ensuring that the insertion rod 2411 slides in the first damping liquid cavity 2421 as the support plate 22 rotates. At the same time, due to the slow sliding speed during adjustment, the damping liquid in the first damping liquid cavity 2421 will not be squeezed during the sliding process.

[0026] Furthermore, if Figure 5 As shown in FIG9 , a rod sleeve 257 is fixed to the bottom end of the lower support rod 251, and the inner wall of the rod sleeve 257 is embedded in the outer wall of the fixed tube 26 and the two are rotatably connected. The second support structure 25 rotates around the fixed tube 26 at a certain angle, and the top of the first connecting tube 256 is connected to the top of the first damping liquid chamber 2421, and the bottom is connected to the middle of the third damping liquid chamber 261 on the same side. The top of the second connecting tube 27 is connected to the bottom of the second damping liquid chamber 2511, and the bottom is connected to the middle of the third damping liquid chamber 261 on the same side, ensuring that the plug rod 2411 and the movable plate 253 will not leak out of the connection during the activity, causing leakage of the damping liquid; In addition, the movable plate 253 has the same size as the second damping liquid chamber 2511, and a plurality of bolt holes 2414 are regularly provided along the rod wall at the top end of the lower support rod 241. The top end of the upper support rod 252 is in the shape of a tuning fork, and the top end of the lower support rod 241 is located in the recessed part of the top end of the upper support rod 252 and the two are fixed by bolts. The tuning fork-shaped upper support rod 252 prevents the upper support rod 252 from blocking the sliding of the lower support rod 241 when the support plate 22 is rotated and adjusted, and at the same time ensures that the two are still connected by bolts after rotation.

[0027] In addition, as shown in FIG6 , the extrusion structure 28 includes a second bevel gear 281 meshing with the bevel gear at the rear end of the linkage rod 223 on the same side, a threaded rod 282 coaxially fixed to the inner side of the second bevel gear 281, and a transmission plate 283 sleeved on the threaded rod 282, the transmission plate 283 is threadedly connected to the threaded rod 282, an extrusion plate cavity 263 is provided at both ends of the fixed cylinder 26, the transmission plate 283 and the threaded rod 282 are both arranged in the extrusion plate cavity 263, an extrusion plate 284 is provided on the outer side of the third damping liquid chamber 261, the extrusion plate 284 has the same size as the third damping liquid chamber 261, and a plurality of transmission rods 285 arranged in a regular annular shape are fixed on the outer side of the extrusion plate 284, and the outer end of the transmission rod 285 passes through the outer side wall of the corresponding third damping liquid chamber 261 and is fixed to the inner side of the transmission plate 283; When the push plate 22 is rotated to adjust the angle, the volume of the concrete above becomes larger and the gravity increases. The push plate 22 drives the first bevel gear 222 to rotate and drives the second bevel gear 281 to rotate through the linkage rod 223, thereby rotating the threaded rod 282, and then drives the extrusion plate 284 to move toward the middle along the third damping liquid chamber 261 through the transmission plate 283, so that the damping fluid in the third damping liquid chamber 261 moves into the second damping liquid chamber 2511 and pushes the movable plate 253 outward, thereby compressing the spring 255 to give the first support structure 24 an upward thrust to ensure that the first support structure 24 will not deform.

[0028] The present invention also provides a supporting method of a casting formwork seismic support device for building construction, using the casting formwork seismic support device for building construction, comprising the following steps: S1, place the base 21 in a suitable position and fix it with bolts, then rotate the support plate 22 to adjust the support angle as needed, so that the front surface of the support plate 22 fits the outer surface of the template 1, and then fix the support plate 22 and the template 1 with bolts; S2. While the plate 22 is rotating, the first bevel gear 222 drives the second bevel gear 281 to rotate through the linkage rod 223, thereby rotating the threaded rod 282, and then driving the extrusion plate 284 to move toward the middle along the third damping liquid chamber 261 through the transmission plate 283, so that the damping liquid in the third damping liquid chamber 261 moves into the second damping liquid chamber 2511 and outwardly presses against the movable plate 253, thereby compressing the spring 255; S3. After the adjustment of the support plate 22 is completed, the lower support rod 241 and the upper support rod 252 are fixed by bolts. After fixing, according to the height of the template 1, the extension plate 23 is pulled upward to a suitable height and then fixed to the template 1 by bolts to complete the support; S4. When the extension plate 23 is pulled upward, the pull rope 231 is gradually tightened and pulls the inner pull plate 233 outward, and the outer pull plate 233 is moved outward through the connecting rod 232 to compress the outer pull plate 233, thereby causing the damping fluid in the third damping fluid chamber 261 to move into the second damping fluid chamber 2511 and press against the movable plate 253 outward and compress the spring 255.
