Description

Technical Field

[0001] This application relates to the field of bridge engineering, and in particular to a safety protection structure for bridge pad construction. Background Technology

[0002] Bridge foundation stone construction involves working at heights, making safety precautions paramount. Foundation stone construction follows the cap beam construction. During cap beam construction, a protective construction system is utilized. After the cap beam construction is completed, this system is retained for foundation stone construction, providing protection for workers. Once the foundation stone construction is finished, the protective system is transferred to the next cap beam construction site.

[0003] During this process, the construction of the foundation stone extends the service life of the protective system and also prolongs the construction cycle of the cap beam, significantly impacting the overall construction schedule. Therefore, there is an urgent need to invent a safe protective structure to safeguard the construction of the foundation stone and ensure that the transfer of the cap beam protective system is not affected. Summary of the Invention

[0004] In order to provide safety protection for the construction of bridge pad stones and to ensure that the transfer of the bridge cap protection system is not affected, this application provides a safety protection structure for the construction of bridge pad stones.

[0005] The technical solution for a bridge padstone construction safety protection structure provided in this application is as follows:

[0006] A safety protection structure for bridge paving stone construction includes a support frame mounted on a cap beam and multiple guardrails mounted around the support frame. The support frame includes multiple vertically arranged uprights and multiple horizontal and longitudinal beams arranged horizontally. The uprights are symmetrically arranged on both sides of the cap beam's width direction, and the horizontal beams are symmetrically arranged on both sides of the cap beam's width direction. The horizontal beams are respectively located at both ends and the middle of the uprights. The longitudinal beams are located at the top of the cap beam, and the two ends of the longitudinal beams are respectively fixedly connected to the horizontal beams in the middle of the uprights on both sides of the cap beam's width direction. The guardrails are mounted on the horizontal beams and uprights in the middle of the uprights.

[0007] By adopting the above technical solution, after the cap beam construction is completed, the support frame is first installed on the cap beam, and then the protective system of the cap beam is removed. The support frame is installed on the cap beam through longitudinal beams, and the transverse beams and uprights abut against both sides of the cap beam in the width direction, thereby limiting the position of the support frame. Finally, guardrails are installed on the transverse beams and uprights, thus completing the installation of the protective structure. This setup uses the protective structure to protect construction personnel, making the protective system of the cap beam less susceptible to disruption during transit, and significantly shortening the bridge construction cycle.

[0008] Preferably, the bottom end of the upright extends to the bottom wall of the cap beam, and the bottom end of the upright is provided with an installation ring. Two symmetrical installation rings on both sides of the width direction of the cap beam are provided with limiting rods, and the limiting rods are provided with fasteners for fixing the limiting rods in the installation rings.

[0009] By adopting the above technical solution, after the support frame is installed, hoisting equipment is used to lift the construction workers. The workers then pass the limiting rod through two symmetrical installation rings in the width direction of the cap beam. The workers then use fasteners to secure the limiting rod, thus installing it at the bottom of the upright. This setup uses the limiting rod to limit the position of the support frame, thereby further improving the stability of the support frame installed on the cap beam and preventing the support frame from tipping over.

[0010] Preferably, the bottom end of the upright extends to below the bottom wall of the cap beam, and a hook is provided at the bottom end of the upright. A turntable is rotatably provided on each of the two uprights at the end of the cap beam along its length. The turntable is located on the side wall of the two uprights in the width direction of the cap beam that are far apart from each other. A connecting rod is slidably provided in the turntable. The ends of the two connecting rods symmetrical in the width direction of the cap beam are fixedly provided with fixing rods along the width direction of the cap beam. The fixing rods are located outside the support frame. The two connecting rods drive the fixing rods to move into the two hooks, and a locking device for fixing the connecting rods is provided in the turntable.

[0011] By adopting the above technical solution, after the support frame is installed, the construction workers first push the two connecting rods. The connecting rods move within the turntable, causing the fixed rod to move away from the support frame. Then, the connecting rods are rotated, causing the turntable to rotate on the upright, thereby moving the fixed rod. The fixed rod moves into the two hooks below the cap beam, and then the locking device is rotated to fix the moving rod, thus securing the fixed rod within the hooks. With this setup, the construction workers can install the fixed rod on the hooks at the bottom of the upright directly on the cap beam, eliminating the need for hoisting equipment and making the installation of the fixed rod more convenient and faster.

[0012] Preferably, a support frame is fixedly installed on the outer side of the crossbeam in the middle of the upright, and the end of the connecting rod away from the turntable abuts against the support frame.

[0013] By adopting the above technical solution, when the connecting rod is not in use, the end of the connecting rod away from the turntable abuts against the support frame, thereby limiting the connecting rod and making it less likely to rotate when not in use.

[0014] Preferably, a drive mechanism for driving the two turntables to rotate together is provided on the longitudinal beam at the end of the cover beam along its length, and a scale is provided on the connecting rod along its own length.

[0015] By adopting the above technical solution, when the fixed rod is moved into the hook, the connecting rod is first adjusted by moving it within the turntable using a scale. This allows the fixed rod to move below the cap beam as the connecting rod rotates. A locking device is then used to lock and secure the connecting rod. Next, the drive mechanism rotates the turntable, which, through the connecting rod, moves the fixed rod below the cap beam. When the fixed rod is directly above the hook, the locking device is released, and the connecting rod slides downwards within the turntable under gravity. The fixed rod then slides into the hook, and the locking device is used again to lock and secure the connecting rod, thus completing the installation of the fixed rod. This design eliminates the need for manual rotation of the connecting rod by construction personnel, making the installation of the fixed rod more convenient and precise.

[0016] Preferably, the drive mechanism includes an outer cover, a drive shaft, a first bevel gear, a second bevel gear, and a handwheel. The outer cover is fixedly mounted on the longitudinal beam, the drive shaft is rotatably mounted inside the outer cover, and both ends of the drive shaft are fixedly connected to two turntables respectively. The first bevel gear is fixedly mounted on the drive shaft, the second bevel gear is rotatably mounted inside the outer cover and meshes with the first bevel gear, and the handwheel is rotatably mounted on the outer cover and fixedly connected to the second bevel gear.

[0017] By adopting the above technical solution, the construction worker rotates the handwheel on the outer cover. The handwheel drives the first bevel gear to rotate through the second bevel gear. The first bevel gear drives two turntables to rotate through the drive shaft. The two turntables drive the fixed rod to rotate through the connecting rod, thereby causing the fixed rod to move automatically.

[0018] Preferably, it also includes a plurality of pads, which are disposed on the cover beam and abut against the lower part of the connection between the crossbeam and the longitudinal beam.

[0019] By adopting the above technical solution, pad blocks are used to support the support frame, so that the longitudinal beams do not directly abut against the top wall of the cap beam, thereby protecting the top surface of the cap beam.

[0020] Preferably, a reinforcing beam is inclinedly provided on the upright, the reinforcing beam is located at the end of the cap beam in the length direction, and the two ends of the reinforcing beam are fixedly connected to the uprights on both sides of the cap beam in the width direction.

[0021] By adopting the above technical solution, the beams are diagonally connected to the uprights in the width direction of the support frame, thereby improving the structural strength of the support frame.

[0022] Preferably, the multiple guardrails are detachably and fixedly connected to each other, the guardrails are set on the crossbeam in the middle of the uprights, and the guardrails are detachably and fixedly connected to the uprights.

[0023] By adopting the above technical solution, the guardrail is installed on the crossbeam and detachably fixedly connected to the uprights. On the one hand, this facilitates the installation of the guardrail on the support frame, and on the other hand, it improves the stability of the guardrail installation. At the same time, the detachable and fixed connection between the guardrails further enhances the stability of the guardrail.

[0024] Preferably, lifting lugs are fixedly installed at the top of the uprights located at the four corners of the cap beam.

[0025] By adopting the above technical solution, the use of lifting lugs makes it easier for construction workers to lift the support frame, thereby facilitating the installation of the protective structure.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By using a support frame and multiple guardrails installed on the support frame to form a protective structure, the protective structure protects the construction personnel on the cap beam, thereby making the protective system of the cap beam less susceptible to impact and significantly shortening the bridge construction cycle.

[0028] 2. By using a limiting rod installed inside the mounting ring at the bottom of the upright to limit the support frame, the stability of the support frame installed on the cap beam is further improved, and the situation of the support frame overturning is prevented.

[0029] 3. By using a drive mechanism to move the fixed rod, the installation of the fixed rod no longer requires the use of hoisting equipment. Construction workers can install the fixed rod on the hook at the bottom of the upright directly on the cap beam, making the installation of the fixed rod more convenient and faster.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0039] This application discloses a safety protection structure for bridge abutment construction.

[0040] Example 1:

[0041] Reference Figure 1 and 2 A safety protection structure for bridge paving stone construction includes a support frame 1 mounted on a cap beam, a guardrail 2 mounted on the support frame 1, and four pads 17 placed on the cap beam. The support frame 1 includes six uprights 11, six crossbeams 12, and seven longitudinal beams 13.

[0042] The uprights 11 are installed vertically, with six uprights 11 symmetrically installed on both sides of the width direction of the cap beam. The crossbeams 12 are installed horizontally, with six crossbeams 12 symmetrically installed on both sides of the width direction of the crossbeams 12. The three uprights 11 and three crossbeams 12 on each side of the width direction of the cap beam are welded to form a grid-shaped frame. The longitudinal beams 13 are installed horizontally, with four longitudinal beams 13 evenly spaced along the length direction of the cap beam. Both ends of the four longitudinal beams 13 are welded and fixed to the crossbeams 12 in the middle of the grid-shaped frame. The three longitudinal beams 13 are evenly spaced along the length direction of the cap beam. Both ends of the three longitudinal beams 13 are welded and fixed to the crossbeams 12 at the top of the grid-shaped frame, thus connecting the two grid-shaped frames and forming the support frame 1.

[0043] Reinforcing beams 18 are welded and fixed at both ends of the support frame 1 along the length of the cap beam. The two ends of the reinforcing beams 18 are welded and fixed to two uprights 11 on both sides of the width of the cap beam, and the reinforcing beams 18 are installed at an angle. The use of reinforcing beams 18 improves the structural strength of the support frame 1.

[0044] Seven guardrails 2 are installed, with three guardrails 2 installed in the upper half of a grid-shaped frame. The three guardrails 2 are placed on the crossbeam 12 in the middle of the grid-shaped frame. Both ends of the three guardrails 2 are detachably fixed to two uprights 11 using bolts and nuts. Adjacent guardrails 2 are also detachably fixed to each other using bolts and nuts. One guardrail 2 is detachably fixed between two uprights 11 at one end of the cap beam along its length using bolts and nuts. The other end of the cap beam along its length is not equipped with a guardrail 2, allowing construction personnel to enter and exit the protective structure.

[0045] The tops of the four uprights 11 at both ends of the cap beam are welded and fixed with lifting lugs 19. After the support frame 1 is welded and assembled, the lifting lugs 19 are hooked onto the support frame 1 using hoisting equipment, allowing it to be lifted and installed on the cap beam. When the support frame 1 is installed on the cap beam, the welded joints of the two longitudinal beams 13 and the transverse beam 12 located in the middle of the cap beam abut against four pads 17. In this application, the uprights 11, transverse beams 12, and longitudinal beams 13 can all be made of angle steel, and the pads 17 can be made of square timber.

[0046] The pad block 17 supports the support frame 1, so that the longitudinal beam 13 inside the support frame 1 will not damage the top wall of the cap beam; the support frame 1 is fitted onto the cap beam, and seven guardrails 2 are installed around the support frame 1, thereby forming a protective structure and protecting the construction personnel, making the protective system of the cap beam less susceptible to interference, and significantly shortening the construction period of the bridge.

[0047] Reference Figure 2 and 3 Four uprights 11 at both ends of the cap beam extend downwards and 10cm beyond the bottom wall of the cap beam. Each of the four uprights 11 has a mounting ring 3 welded to its bottom. Two symmetrical mounting rings 3 in the width direction of the cap beam have limiting rods 4 threaded through them. Two fixing parts 5 are threaded onto the limiting rods 4, and each fixing part 5 abuts against the opposite sidewalls of the two mounting rings 3. In this application, the fixing parts 5 can be nuts, and the diameter of the nuts is larger than the inner diameter of the mounting rings 3.

[0048] After the support frame 1 is installed, the construction workers use lifting equipment to install two limiting rods 4 inside the four mounting rings 3. Then, they install four fasteners 5 at both ends of the two limiting rods 4, ensuring that the fasteners 5 are pressed against the mounting rings 3, thereby fixing the limiting rods 4. Using the limiting rods 4 to limit the support frame 1 further improves the stability of the support frame 1 installed on the cap beam and prevents the support frame 1 from tipping over.

[0049] The implementation principle of Embodiment 1 of this application is as follows: a protective structure is formed by a support frame 1 and seven guardrails 2 installed on the support frame 1. The protective structure protects the construction personnel on the cap beam, thereby making the protective system of the cap beam less susceptible to interference and significantly shortening the construction period of the bridge.

[0050] Example 2:

[0051] Referring to 4 and 5, the difference between this embodiment and embodiment 1 is that a turntable 7 is installed on each of the four uprights 11 at both ends of the length direction of the cap beam via a connecting plate. Each turntable 7 is rotatably installed on the outside of the welded joint between the crossbeam 12 and the upright 11 in the middle of the upright 11 with the width direction of the cap beam as the axis.

[0052] Each turntable 7 has a connecting rod 8 slidably installed along its own diameter. A support frame 14 is welded and fixed to the outer wall of the crossbeam 12 in the middle of the upright 11, and the connecting rod 8 passes through the support frame 14. The support frame 14 limits the connection rod 8 so that the turntable 7 will not drive the connecting rod 8 to rotate when the support frame 1 is installed.

[0053] The ends of the connecting rod 8 are welded and fixed with fixing rods 9 along the width direction of the cap beam. The two ends of each fixing rod 9 are welded and fixed to the ends of the two connecting rods 8 on both sides of the width direction of the cap beam, and the fixing rods 9 are located on the outside of the support frame 1 along the length direction of the cap beam.

[0054] A locking element 10 is threaded along its own diameter inside the turntable 7. The locking element 10 is perpendicular to the connecting rod 8, and its end abuts against the outer wall of the connecting rod 8. In this application, the locking element 10 can be a bolt. Rotating the locking element 10 can fix the connecting rod 8 inside the turntable 7. Hooks 6 are welded to the bottom ends of the four uprights 11 at both ends of the cap beam along its length, and the openings of the hooks 6 face away from the middle of the cap beam.

[0055] Using hoisting equipment, the support frame 1 is installed on the cap beam. At this time, the guardrail 2 is not installed on the support frame 1. The construction workers slide the connecting rod 8 away from the cap beam. The connecting rod 8 slides within the turntable 7 and then slides out of the support frame 14. Simultaneously, the two connecting rods 8 drive a fixed rod 9 to move away from the cap beam. Then, the connecting rod 8 is rotated, causing the fixed rod 9 to move below the cap beam. When the fixed rod 9 moves into the hook 6, the locking member 10 on the turntable 7 is rotated. The locking member 10 abuts against the connecting rod 8, thereby fixing the fixed rod 9 in the hook 6. After the fixed rod 9 is installed, the guardrail 2 is then installed on the support frame 1.

[0056] The fixing rod 9 is used to limit the position of the support frame 1, thereby improving the stability of the support frame 1 on the cap beam and preventing the support frame 1 from tipping over. Moreover, the construction personnel can install the fixing rod 9 on the hook 6 at the bottom of the upright 11 directly on the cap beam, without the need for hoisting equipment, making the installation of the fixing rod 9 more convenient and quick.

[0057] Example 3:

[0058] Reference Figure 6 and 7 The difference between this embodiment and embodiment 2 is that two drive mechanisms 15 are installed inside the support frame 1, and the drive mechanisms 15 drive the two turntables 7 on both sides of the cover beam to rotate synchronously.

[0059] Specifically, the drive mechanism 15 includes an outer cover 151, a drive shaft 152, a first bevel gear 153, a second bevel gear 154, and a handwheel 155. The outer cover 151 is fixedly installed in the middle of the longitudinal beam 13 located at the end of the cover beam along the length direction and between the two turntables 7. The drive shaft 152 is rotatably installed inside the outer cover 151 along the width direction of the cover beam. Both ends of the drive shaft 152 extend to the outside of the outer cover 151 and are fixedly connected to the two turntables 7.

[0060] The first bevel gear 153 is coaxially fixedly mounted on the drive shaft 152 and located inside the outer cover 151. The second bevel gear 154 is rotatably mounted inside the outer cover 151 and meshes with the first bevel gear 153. The handwheel 155 is rotatably mounted on the outer cover 151 via a bearing, and the shaft of the handwheel 155 is fixedly connected to the second bevel gear 154. A scale 16 is engraved on the outer side wall of the connecting rod 8 along its circumferential direction.

[0061] After the support frame 1 is installed, first adjust the connecting rod 8 by sliding it within the turntable 7 according to the scale 16, so that when the connecting rod 8 rotates, the fixing rod 9 can rotate to the bottom of the cap beam. Then, rotate the locking member 10 to fix the connecting rod 8. The construction worker rotates the handwheel 155, which drives the two turntables 7 to rotate synchronously via the second bevel gear 154, the first bevel gear 153, and the drive shaft 152. The turntables 7, through the connecting rod 8, move the fixing rod 9 to the bottom of the cap beam, positioning the fixing rod 9 directly above the hook 6. At this point, rotating the locking member 10 unlocks the connecting rod 8. Under the influence of gravity, the connecting rod 8 slides downwards within the turntable 7, causing the fixing rod 9 to slide into the hook 6. Then, rotating the locking member 10 again fixes the connecting rod 8, completing the installation of the fixing rod 9. This eliminates the need for manual rotation of the connecting rod 8, making the installation of the fixing rod 9 more convenient and precise.

[0062] After the fixing rod 9 is installed, the guardrail 2 is installed on the support frame 1. The guardrail 2 has a clearance opening to allow the drive shaft 152 to pass, so that the guardrail 2 will not interfere with the drive shaft 152 after it is installed on the support frame 1.

[0063] 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.
