Description

Technical Field

[0001] This application relates to the field of bridge engineering, and in particular to a method for reinforcing the installation of cap beam formwork. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a bridge pier to support, distribute, and transfer the load of the superstructure. It is also called a cap beam. It is a reinforced concrete or lightly reinforced concrete beam installed on the pier (abutment) or on the piles. Its main function is to support the bridge superstructure and transfer all the load to the substructure. Sometimes the cap beam is directly connected to the bridge pile, and sometimes it is connected to the column first.

[0003] Currently, the construction of cap beams requires first pouring the pier columns, then fixing the clamps on the pier columns, and then laying out the steel beams on top of the clamps. After the laying is completed, the formwork for building the cap beams can be erected on the steel beams. After the formwork is erected, the cap beams can be poured.

[0004] The inventors discovered at least the following problems with this technology: During the pouring of the cap beam, the clamps need to bear the entire weight of the steel beam and the formwork, and the entire pouring process takes a certain amount of time. Therefore, there is a certain safety risk. Once the clamps loosen, they can easily cause a certain safety risk to the workers. Summary of the Invention

[0005] To address the safety risks to workers that can arise from loose clamps, this application provides a method for reinforcing the installation of cap beam formwork.

[0006] The technical solution for the reinforcement method of cap beam formwork installation provided in this application is as follows: A method for reinforcing the installation of a cap beam formwork includes the following steps: S1: Secure the support clamp to the column and fix the jack to the support clamp; S2: Fix the anti-pull clamp to the column and position it above the support clamp, and suspend the support clamp with the suspension component on the anti-pull clamp; S3: Fix the I-beam to the push shaft of the jack, and lay several sub-beams on the top of the I-beam and fix them to the I-beam; S4: Erect the bottom formwork on the sub-beam, install the side formwork on top of the bottom formwork and surround it to form a rectangle, and finally fix the adjacent side formwork.

[0007] By adopting the above technical solution, during the period when the supporting clamp is bearing the load, the anti-tension clamp can be suspended by the suspension component, so that the supporting clamp can better bear the load and facilitate the subsequent construction of the cap beam, thereby improving safety.

[0008] Optionally, the specific steps of step S4 are as follows: S4.1: The bottom formwork is erected on the sub-beam, and the side formwork is positioned using the positioning components on the bottom formwork to achieve the effect of pre-installation; S4.2: The positioning component also has a supporting function to support the side template, thereby improving the stability of the side template; S4.3: Secure the adjacent side templates with bolts and nuts.

[0009] By adopting the above technical solution, the positioning component can not only pre-install the side template to improve the installation efficiency of the side template, but also support the side template to improve its stability.

[0010] Optionally, a ring plate is fixedly provided on the anti-pull clamp and the ring plate abuts against the column. The suspension assembly includes an abutment part, a counter-pressure part, a suspension part, and a connecting part. The abutment part, the counter-pressure part, and the suspension part are all provided on the ring plate. The abutment part abuts against the column. One end of the counter-pressure part abuts against the abutment part, and the other end abuts against the suspension part. The suspension part is connected to the support clamp through the connecting part.

[0011] By adopting the above technical solution, when the support clamp is bearing load, the suspension part will suspend the support clamp and the suspension part will tend to be taut. At this time, the suspension part has a pulling tendency on the counter-pressure part, and the counter-pressure part will have a counter-pressure tendency on the abutment part, so as to have an inclined downward thrust on the abutment part, thereby making the abutment part and the column abut more tightly, and the friction between the abutment part and the column increases and moves upward, so as to better suspend the support clamp, so that the support clamp can better bear the load and facilitate the subsequent construction of the cap beam, thereby improving safety.

[0012] Optionally, the abutting part includes an abutting plate, a corrugated plate, and an abutting spring. An abutting hole is provided on the ring plate. The abutting plate is inserted into the abutting hole. The corrugated plate is fixed to the abutting plate and abuts against the column. The abutting spring is fixed between the abutting plate and the inner wall of the abutting hole. The end of the counter-pressure part away from the suspension part abuts against the abutting plate.

[0013] By adopting the above technical solution, during the process of the suspension part having a pulling tendency on the counter-pressure part, the counter-pressure part will have a counter-pressure tendency on the abutment plate, so as to have an inclined downward thrust on the abutment plate, thereby making the corrugated plate and the column abut more tightly.

[0014] Optionally, the counter-pressure part includes a reversing rod and a counter-pressure rod. The counter-pressure rod is fixed to the abutment plate and is inclined. The reversing rod is rotatably installed in the abutment hole, with one end abutting against the counter-pressure rod and the other end abutting against the suspension part.

[0015] By adopting the above technical solution, when the support clamp is bearing weight, the suspension part will suspend the support clamp and the suspension part will tend to be taut; at this time, the suspension part has a tendency to pull the reverse rod, and the end of the reverse rod near the suspension part will have a tendency to flip upward, while the other end will have the opposite, thus having a counter-pressure effect on the counter-pressure rod.

[0016] Optionally, the suspension part includes a suspension rod and a suspension rope. The suspension rod is rotatably installed in the abutment hole, with one end abutting against the reversing rod and the other end fixed to the suspension rope. The suspension rope passes through the ring plate and is connected to the support clamp through the connecting part.

[0017] By adopting the above technical solution, when the support clamp is bearing weight, the suspension rope will suspend the support clamp; at this time, the suspension rope will have a downward pulling tendency on the end of the suspension rod connected to itself, so that the end of the suspension rod away from the suspension rope has an upward lifting effect on the end of the reversing rod away from the counter-pressure rod; then the other end of the reversing rod has a downward flipping tendency, thus having a counter-pressure effect on the counter-pressure rod.

[0018] Optionally, the connecting part includes a connecting hook and a connecting ring, the connecting ring being fixed to the ring plate, the connecting hook being fixed to the suspension rope, and the connecting hook being hung on the connecting ring.

[0019] By adopting the above technical solution, after the cap beam is constructed, the connecting hook can be removed from the connecting ring, thus separating the suspension rope from the support clamp, without affecting the disassembly of the anti-pull clamp and the support clamp.

[0020] Optionally, the positioning component includes a positioning part and a support part, a positioning strip is provided on the side template, the positioning strip is connected to the positioning part, and the support part is provided on the positioning part.

[0021] By adopting the above technical solution, after the bottom formwork is erected, the side formwork is pre-installed by connecting the positioning strips and positioning parts on the side formwork, and then the adjacent side formwork is fixed by bolts and nuts, thereby improving the efficiency of side formwork installation; after the side formwork is installed, the side formwork can be supported by the support parts, thereby improving the stability of the side formwork.

[0022] Optionally, the positioning part includes a positioning block, a fixing groove is provided on the bottom template, the positioning block is slidably installed in the fixing groove, the positioning block is provided with a positioning groove, the positioning strip is inserted into the positioning groove, and the support part is provided on the positioning block.

[0023] By adopting the above technical solution, after the bottom template is erected, the side template can be pre-installed by inserting the positioning strips on the side template into the positioning slots.

[0024] Optionally, the support part includes a slider, a support rod, and a support plate. The positioning block includes a fixed block and a movable block. The fixed block and the movable block are fixed together by a fixing component, and the fixed block is slidably installed in the fixing groove. The movable block has a receiving groove. The slider is slidably connected to the inner wall of the receiving groove. One end of the support rod is hinged to the slider, and the other end is hinged to the support plate.

[0025] By adopting the above technical solution, after the positioning strip is inserted into the positioning groove, the moving block is lifted upward until the support rod is fully extended out of the receiving groove and the support rod is tilted; then the moving block is lowered downward until the support plate abuts against the sub-beam to support the side formwork, thereby improving the stability of the side formwork.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. During the period when the supporting clamp is bearing the load, the anti-tension clamp can be suspended by the suspension component, so that the supporting clamp can better bear the load and facilitate the subsequent construction of the cap beam, thereby improving safety.

[0027] 2. After the cap beam is completed, the connecting hook can be removed from the connecting ring to separate the suspension rope from the support clamp, thus not affecting the disassembly of the anti-pull clamp and the support clamp.

[0028] 3. After the positioning strip is inserted into the positioning groove, lift the moving block upward until the support rod is fully extended out of the receiving groove and tilt the support rod; then lower the moving block downward until the support plate abuts against the sub-beam to support the side formwork, thereby improving the stability of the side formwork.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a method for reinforcing the installation of a cap beam formwork.

[0033] A method for reinforcing the installation of a cap beam formwork includes the following steps: S1: Fix the support clamp 12 to the column 1, and fix the jack to the support clamp 12; S2: Fix the anti-pull clamp 13 to the column 1 and position it above the support clamp 12, and suspend the support clamp 12 with the suspension component on the anti-pull clamp 13; S3: Fix the I-beam to the push shaft of the jack, and lay several sub-beams on the top of the I-beam and fix them to the I-beam; the jack can be adjusted according to the height of the column to adjust the actual height of the I-beam, so as to facilitate the construction work. S4: Erect the bottom formwork 2 on the beam, and install the side formwork 22 on top of the bottom formwork 2 and surround it to form a rectangle. Finally, fix the adjacent side formwork 22. S4.1: The bottom formwork 2 is erected on the sub-beam, and the side formwork 22 is positioned by the positioning components on the bottom formwork 2 to achieve the effect of pre-installation; S4.2: The positioning component also has a supporting function to support the side template 22, thereby improving the stability of the side template 22; S4.3: Secure the adjacent side templates 22 with bolts and nuts.

[0034] Reference Figure 1The positioning component includes a positioning part 7 and a support part 8. A positioning strip 221 is fixedly installed on the outward side of the side template 22, and the positioning strip 221 is I-shaped. Two positioning strips 221 are provided on a single side template 22. The positioning strips 221 are connected to the positioning part 7. After the bottom template 2 is erected, the positioning strips 221 on the side template 22 are connected to the positioning part 7 to pre-install the side template 22. Then, the adjacent side templates 22 are fixed with bolts and nuts, thereby improving the efficiency of the side template 22 installation. After the side template 22 is installed, the support part 8 can support the side template 22 to improve the stability of the side template 22.

[0035] Reference Figure 1 The positioning part 7 includes a positioning block 71. A fixing groove 21 is formed on the top of the bottom template 2 along its circumferential outer edge. The positioning block 71 is slidably installed in the fixing groove 21, allowing adjustment of its position according to the width of the side template 22. A positioning groove 7111 is formed on the side wall of the positioning block 71, with the top and bottom of the positioning block 71 penetrating through it. A positioning strip 221 is inserted into the positioning groove 7111. After the bottom template 2 is erected, the side template 22 can be pre-installed by inserting the positioning strip 221 from the side template 22 into the positioning groove 7111. Then, adjacent side templates 22 are fixed using bolts and nuts, thus improving the efficiency of side template 22 installation. In this embodiment, adjacent side templates 22 share a single positioning block 71.

[0036] Reference Figure 2 and Figure 3 The support part 8 includes a slider 81, a support rod 82, and a support plate 83. The positioning block 71 includes a fixed block 711 and a movable block 712. The fixed block 711 is slidably installed in the fixed groove 21. A rod is fixedly provided on the top of the fixed block 711. The movable block 712 is sleeved on the rod and can slide vertically on the rod to limit the movement of the movable block 712 and prevent it from deviating.

[0037] Reference Figure 3The bottom of the movable block 712 has a receiving groove 7121, and the slider 81 is slidably installed in the receiving groove 7121 but cannot be completely slid out of the receiving groove 7121. One end of the support rod 82 is hinged to the slider 81 and the other end is hinged to the support plate 83. The initial state of the support plate 83 is that it is completely contained in the receiving groove 7121 and abuts against the top wall of the fixed block 711. After the positioning strip 221 is inserted into the positioning groove 7111, the moving block 712 is first raised to a certain height so that the support plate 83 can slide out of the receiving groove 7121 by its own weight, and the support rod 82 can be tilted away from the side template 22. Then, the moving block 712 is lowered until the support plate 83 abuts against the bottom template 2 and the support rod 82 abuts against the bottom wall of the moving block 712 and the top wall of the fixed block 711, making it difficult to flip over again, thus ensuring the stability of the support rod 82. Furthermore, the weight of the moving block 712 can press down on the support rod 82, thereby supporting the side template 22 and improving its stability. This positioning component not only positions the side template 22 to achieve a pre-installation effect, but also supports the side template, thus achieving a dual effect.

[0038] Reference Figure 4 An annular plate 14 is fixedly installed on the inner side wall of the anti-tension clamp 13, and the annular plate 14 abuts against the side wall of the column 1. The suspension assembly includes an abutment part 3, a counter-pressure part 4, a suspension part 5, and a connecting part 6. The abutment part 3, the counter-pressure part 4, and the suspension part 5 are all provided on the annular plate 14, and the abutment part 3 abuts against the side wall of the column 1. One end of the counter-pressure part 4 abuts against the abutment part 3, and the other end abuts against the suspension part 5. The counter-pressure part 4 is used to counter-pressure the abutment part 3 so that the abutment part 3 abuts against the column 1 more tightly.

[0039] Reference Figure 4 The end of the suspension part 5 away from the counter-pressure part 4 is connected to the support clamp 12 through the connecting part 6. When the support clamp 12 is under load, the suspension part 5 will suspend the support clamp 12 and the suspension part 5 will tend to be taut. At this time, the suspension part 5 has a pulling tendency on the counter-pressure part 4, and the counter-pressure part 4 will have a counter-pressure tendency on the abutment part 3, so as to have an inclined downward thrust on the abutment part 3 (the thrust is inclined towards the side closer to the column 1), so that the abutment part 3 and the column 1 are more tightly abutted, and the friction between the abutment part 3 and the column 1 increases and moves upward, so as to better suspend the support clamp 12, so that the support clamp 12 can better bear the load and facilitate the subsequent construction of the cap beam, thereby improving safety.

[0040] Reference Figure 4The abutment part 3 includes an abutment plate 31, a corrugated plate 32, and an abutment spring 33. An abutment hole 141 is provided on the side of the ring plate 14 facing the column 1, and the abutment plate 31 is inserted into the abutment hole 141. The corrugated plate 32 is fixedly connected to the side of the abutment plate 31 near the column 1. The corrugated plate 32 is made of rubber and can increase the friction between the abutment plate 31 and the column 1. One end of the abutment spring 33 is fixed to the side of the abutment plate 31 away from the column 1, and the other end is fixed to the bottom of the abutment hole 141. The abutment spring 33 can push the abutment plate 31 towards the column 1. During the process where the suspension part 5 has a pulling tendency towards the counter-pressure part 4, the counter-pressure part 4 will have a counter-pressure tendency towards the abutment plate 31, so as to exert a downward inclined pushing force on the abutment plate 31, thereby making the corrugated plate 32 abut against the column 1 more tightly.

[0041] Reference Figure 4 The counter-pressure part 4 includes a reversing rod 41 and a counter-pressure rod 42. The reversing rod 41 is rotatably installed in the abutment hole 141 via a rotating shaft. The counter-pressure rod 42 is fixed to the side of the abutment plate 31 near the abutment spring 33 and is inclined, with the end of the counter-pressure rod 42 away from the abutment plate 31 inclined upward. One end of the reversing rod 41 abuts against the end of the counter-pressure rod 42 away from the abutment plate 31, and the other end abuts against the suspension part 5. When the support clamp 12 is under load, the suspension part 5 will suspend the support clamp 12 and the suspension part 5 will tend to be taut; at this time, the suspension part 5 has a tendency to pull the reversing rod 41, and the end of the reversing rod 41 near the suspension part 5 will tend to flip upward, while the other end will do the opposite, thus exerting a counter-pressure effect on the counter-pressure rod 42.

[0042] Reference Figure 4 The suspension unit 5 includes a suspension rod 51 and a suspension rope 52. The suspension rod 51 is rotatably installed in the abutment hole 141 via a pivot, with one end abutting against the bottom of the reversing rod 41 away from the counter-pressure rod 42, and the other end fixed to the suspension rope 52. The end of the suspension rope 52 away from the suspension rod 51 passes through the inner wall of the abutment hole 141 and is connected to the support clamp 12 via the connecting part 6. The initial state of the suspension rope 52 is a taut state. When the support clamp 12 is under load, the suspension rope 52 will suspend the support clamp 12. At this time, the suspension rope 52 will have a downward pulling tendency on the end of the suspension rod 51 connected to itself, so that the end of the suspension rod 51 away from the suspension rope 52 has an upward lifting effect on the end of the reversing rod 41 away from the counter-pressure rod 42; then the other end of the reversing rod 41 has a downward flipping tendency, thus having a counter-pressure effect on the counter-pressure rod 42.

[0043] Reference Figure 4The connecting part 6 includes a connecting hook 61 and a connecting ring 62, with the connecting ring 62 fixedly installed on the top of the support clamp 12. The connecting hook 61 is fixed to the end of the suspension rope 52 away from the suspension rod 51, and the connecting hook 61 is hung on the connecting ring 62. After the cap beam is constructed, the connecting hook 61 can be removed from the connecting ring 62, thus separating the suspension rope 52 from the support clamp 12 without affecting the disassembly of the counter-tension clamp 13 and the support clamp 12.

[0044] The implementation principle of the beam formwork installation reinforcement method in this application embodiment is as follows: When the support clamp 12 is under load, the suspension rope 52 will suspend the support clamp 12; at this time, the suspension rope 52 will have a downward pulling tendency on the end of the suspension rod 51 connected to itself, so that the end of the suspension rod 51 away from the suspension rope 52 has an upward lifting effect on the end of the reversing rod 41 away from the counter-pressure rod 42; then the other end of the reversing rod 41 has a downward flipping tendency, thus having a counter-pressure effect on the counter-pressure rod 42.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
