Description

Technical Field

[0001] This utility model belongs to the field of cap beam lifting construction technology, and specifically relates to a cap beam lifting construction device. Background Technology

[0002] A cap beam is a horizontal beam installed on top of a 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 horizontal beam installed on the pier or on the piles. Its main function is to support the superstructure of the bridge and transfer all the load to the substructure.

[0003] Application No. 202120852822.8 provides a bridge pier construction device, which uses a detachable connection method to connect the driving component to the fixed platform, so as to realize the quick disassembly between the driving component and the fixed platform, thereby facilitating the disassembly of the driving component after the bridge pier construction is completed, and facilitating the repair and replacement of the driving component when it is damaged.

[0004] However, when installing jacks on existing piers, most of them are installed on the clamps. Due to the shape of the clamps and the cap beam, a maximum of four jacks can be installed on the top of the clamps. This results in a small number of jacks on a single pier to lift the cap beam, causing the jacks to be subjected to greater force, affecting the stability of the cap beam lifting, and making it less practical. Utility Model Content

[0005] To address the issue of insufficient jack quantity in existing technologies, this invention provides a girder lifting construction device. This device utilizes mounting components in conjunction with jacks to achieve the effect of installing multiple jacks on a single fixed platform. The specific technical solution is as follows: A girder lifting construction device includes: a pier column; a fixed platform is fitted onto the outer wall of the pier column; two mounting components are symmetrically installed on the top of the fixed platform; multiple top grooves are equidistantly spaced on the top of each mounting component; jacks are installed within these top grooves; an outer groove is formed on the outer wall of each mounting component; a bolt is installed at the bottom inner part of the outer groove, and the bolt engages with the fixed platform; a girder mold is installed at the output end of each jack.

[0006] Preferably, the bottom of the mounting component has two symmetrical bottom grooves, a connecting cylinder is hinged in the bottom groove, and a sliding groove is provided at the end of the connecting cylinder away from the hinge, and an inner sliding rod is slidably connected in the sliding groove.

[0007] Preferably, two outer blocks are symmetrically installed on the outer wall of the fixed platform, and hanging rings are installed on both sides of the outer wall of the outer blocks; a hook is installed at the end of the inner slide rod away from the connecting cylinder, and the hooks correspond one-to-one with the hanging rings, and the hooks are adapted to the hanging rings.

[0008] Preferably, a limiting groove is formed on the inner wall of the slide groove, and a limiting block is slidably connected in the limiting groove, the limiting block being connected to the inner slide rod.

[0009] Preferably, the inner slide rod has multiple slots equidistantly provided on the outer wall of the side away from the limiting groove, and the connecting cylinder has a threaded hole on the outer wall of the connecting cylinder. The threaded hole is located on the side close to the hook, and a bolt is threaded into the threaded hole. The bolt is adapted to the slot.

[0010] Preferably, a side groove is formed on the side wall of the bottom groove, and a baffle is slidably connected in the side groove, the baffle being located below the connecting cylinder.

[0011] In addition, the cap beam lifting construction device in the above-mentioned technical solution provided by this utility model may also have the following additional technical features: a through hole is provided at the bottom of the side groove, and a slidable block is connected in the through hole.

[0012] In the above technical solution, the toggle block is connected to the baffle.

[0013] Compared with the prior art, the beneficial effects of this girder lifting construction device are as follows: The device uses bolt one to fix the installation component to the fixed platform, and then installs jacks sequentially in the top groove, increasing the number of jacks to reduce the pressure on a single jack and improve the stability of the girder lifting. By sliding the lever, the baffle enters the side groove, and then the connecting cylinder is rotated, sliding the inner sliding rod to a suitable length. The hook is then hung on the hanging ring, and bolt two is inserted into the threaded hole and tightened, allowing bolt two to enter the corresponding slot, thus fixing the position of the connecting cylinder and the inner sliding rod. This improves the support of the connecting cylinder and the inner sliding rod for both ends of the installation component, making it highly practical. Attached Figure Description

Detailed Implementation

[0019] The following are specific implementation cases and appendices. Figures 1-5 This utility model will be further described below, but it is not limited to these embodiments. This utility model provides a technical solution: a cap beam lifting construction device, comprising: a pier 1, a fixed platform 2 fitted onto the outer wall of the pier 1, the fixed platform 2 using a clamp structure, the clamp being made of two semi-circular arc steel plates and connected and clamping the pier 1 by high-strength bolts, thereby generating friction to balance the upper load; the tightening torque of the clamp bolts should meet the calculated requirements; to improve the friction between the pier 1 and the clamp, and to protect the surface of the pier 1, a 10 mm rubber pad is placed between the pier 1 and the clamp. Install clamps at designated locations; two mounting pieces 3 are symmetrically installed on the top of the fixed platform 2. Multiple top grooves 4 are equidistantly opened on the top of the mounting pieces 3. Jacks 5 are installed in the top grooves 4. An outer groove 6 is opened on the outer wall of the mounting piece 3. The outer groove 6 is located at the center of the mounting piece 3. A bolt 7 is installed at the bottom of the inner side of the outer groove 6. The bolt 7 cooperates with the fixed platform 2 and fixes the mounting piece 3 to the fixed platform 2 through the bolt 7; a cap beam mold 8 is installed at the output end of the jack 5; in order to make the pier 1 and the cap beam mold 8 fit tightly, the top of the pier 1 needs to be roughened. The roughening should be done to expose the concrete aggregate, and then it should be washed clean with water.

[0020] As a preferred option, the bottom of the mounting component 3 is symmetrically provided with two bottom grooves 9, and a connecting cylinder 10 is hinged in the bottom groove 9. The hinge ends of the two connecting cylinders 10 are located on opposite sides of the two bottom grooves 9 respectively. A sliding groove 11 is provided at the end of the connecting cylinder 10 away from the hinge, and an inner sliding rod 12 is slidably connected in the sliding groove 11.

[0021] As a preferred option, two outer blocks 14 are symmetrically installed on the outer wall of the fixed platform 2. The outer blocks 14 are located at the top of the outer arc of the clamp. Hanging rings 15 are installed on both sides of the outer wall of the outer blocks 14. A hook 13 is installed at the end of the inner slide rod 12 away from the connecting cylinder 10. The hook 13 corresponds to the hanging ring 15 one by one. The hook 13 and the hanging ring 15 are adapted to each other. The connection between the connecting cylinder 10 and the clamp is completed by hanging the hook 13 on the hanging ring 15.

[0022] As a preferred option, a limiting groove 16 is provided on the inner wall of the slide groove 11, and a limiting block 17 is slidably connected in the limiting groove 16. The limiting block 17 is connected to the inner slide rod 12. By setting the limiting groove 16 and the limiting block 17, the inner slide rod 12 can slide linearly in the slide groove 11, thus preventing the inner slide rod 12 from rotating.

[0023] As a preferred option, furthermore, multiple slots 18 are equidistantly provided on the outer wall of the inner slide rod 12 on the side away from the limiting groove 16. The multiple slots 18 are arranged along the direction of the inner slide rod 12. A threaded hole 19 is provided on the outer wall of the connecting cylinder 10. The threaded hole 19 and the slot 18 are located in the same direction. The threaded hole 19 is located on the side close to the hook 13. A bolt 20 is internally threaded into the threaded hole 19. The bolt 20 is adapted to the slot 18.

[0024] As a preferred option, a side groove 21 is provided on the side wall of the bottom groove 9, and a baffle 22 is slidably connected in the side groove 21. The baffle 22 is located below the connecting cylinder 10. The baffle 22 slides into the bottom groove 9 to block the connecting cylinder 10 and prevent the connecting cylinder 10 from rotating downward and extending out of the bottom groove 9.

[0025] As a preferred embodiment, the bottom of the side groove 21 is provided with a through hole, and a lever 23 is slidably connected in the through hole. The lever 23 extends out of the bottom of the mounting part 3 and is connected to the baffle 22. By sliding the lever 23, the baffle 22 is slidable, and the position of the baffle 22 is adjusted.

[0026] The piers, fixed platforms, jacks, and cap beam molds in this case are existing technologies. The piers, fixed platforms, jacks, and cap beam molds all have the same structure and connection method as those in the cited documents. As long as the piers, fixed platforms, jacks, and cap beam molds meet the requirements of this case, they are acceptable.

[0027] Working principle: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. After installation, first check the installation, fixation, and safety protection of this utility model before use. Before use, the construction of the cap beam is divided into various forms depending on the support frame used, such as the ground support method, the clamp method, and the star-shaped rod method. High piers generally use the clamp method and the star-shaped rod method, while low piers with higher foundations generally use ground supports. Before support, various support frames need to be designed and calculated to meet the construction bearing capacity requirements. During use, the fixed platform 2 is installed on the pier column 1, and the mounting part 3 is placed on top of the fixed platform 2. The outer groove 6 is aligned with the top hole of the fixed platform 2, and bolts 7 are used to secure it. The mounting component 3 is fixedly connected to the fixed platform 2. Then, the user slides the lever 23, causing the lever 23 to drive the baffle 22 to slide. The baffle 22 disengages from the bottom groove 9 and enters the side groove 21. The user rotates the connecting cylinder 10 and slides the inner slide rod 12 outward, hooking the hook 13 of the inner slide rod 12 onto the corresponding hanging ring 15. Then, the second bolt 20 is inserted into the threaded hole 19 and rotated, tightening the second bolt 20 into the corresponding slot 18, fixing the positions of the connecting cylinder 10 and the inner slide rod 12, thereby improving the support of the connecting cylinder 10 and the inner slide rod 12 for both ends of the mounting component 3. Subsequently, the user installs the jack 5 in the top groove 4 in sequence and sets the cover beam mold 8 at the output end of the jack 5, thereby controlling the lifting operation of the cover beam mold 8.
