Description

Technical Field

[0001] This utility model relates to the field of cap beam construction technology, and in particular to an adjustable pile-slab bridge cap beam support structure. Background Technology

[0002] A cap beam is a horizontal beam installed on top of the piers of a bridge frame to support, distribute, and transfer the loads of the superstructure. Its main function is to support the superstructure and transfer all loads to the substructure. In pile-slab bridge construction, the cap beam, as a key component connecting the piles and the upper beams, directly impacts the project quality and construction efficiency during its construction process.

[0003] For example, Chinese Patent No. CN222648591U discloses a bridge cap beam construction clamp support structure, relating to the field of bridge cap beam construction technology. It includes a bridge mechanism comprising a pier, with clamp one and clamp two fixedly installed on the side of the pier. Support rod one is fixedly installed on both sides of clamp one, and support rod two is slidably installed on the inner sides of both support rods one. Support blocks are fixedly installed on both sides of clamp two, and connecting rods are rotatably installed on the inner sides of both support blocks via connecting shafts. Support plates are rotatably installed on the ends of both connecting rods away from the support blocks via connecting shafts. Crossbeams are slidably installed on the upper sides of both support plates, and slider one and slider two are slidably installed on the upper sides of the support plates. This utility model utilizes a designed hydraulic rod structure. The hydraulic rod is fixed to the sides of slider one and slider two via a fixing frame structure. The hydraulic rod achieves extension and retraction via a variable-voltage motor, thereby achieving the effect of pushing the slider structure.

[0004] However, the height of the crossbeams of the aforementioned support structure depends entirely on the installation position of the clamps on the piers. The crossbeams themselves do not have the ability to adjust longitudinally. When the design height of the cap beam changes or the support elevation needs to be finely adjusted during construction, the clamps need to be removed and repositioned for installation. This not only increases the safety risks of working at heights, but also leads to repeated construction procedures, extended construction period, and seriously affects construction efficiency.

[0023] Example 1: This utility model embodiment provides an adjustable pile-slab bridge cap beam support structure, such as... Figures 1-5 As shown, it includes: two semi-circular clamps 1, which are symmetrically installed on the outside of the pier column 2. The front and rear ends of the semi-circular clamps 1 are respectively provided with first connecting ears 3. The first connecting ears 3 between the two semi-circular clamps 1 are connected by first fasteners. An arc-shaped hole 4 is provided inside the semi-circular clamp 1. The upper end of the arc-shaped hole 4 is connected to the top of the semi-circular clamp 1. An arc-shaped plate 5 is slidably arranged inside the arc-shaped hole 4. A support plate 6 is fixedly arranged on the upper end of the arc-shaped plate 5. The support plate 6 is used to support the precast cap beam 7. A fixing plate 8 is provided on the outer wall of the semi-circular clamp 1. A hydraulic rod 9 is provided on the upper end of the fixing plate 8. The upper end of the hydraulic rod 9 is connected to the lower surface of the support plate 6. The front and rear ends of the arc plate 5 are respectively provided with second connecting ears 10, and the second connecting ears 10 between the two arc plates 5 are connected by second fasteners; A first reinforcing plate 11 is provided on the lower surface of the fixing plate 8. The upper end of the first reinforcing plate 11 is connected to the lower surface of the fixing plate 8, and the side wall of the first reinforcing plate 11 is fixedly connected to the outer wall of the semi-circular clamp 1. A second reinforcing plate 12 is provided on the lower surface of the support plate 6. The upper end of the second reinforcing plate 12 is connected to the lower surface of the support plate 6, and the side wall of the second reinforcing plate 12 is fixedly connected to the outer wall of the arc plate 5. Several second reinforcing plates 12 are provided, and the several second reinforcing plates 12 are distributed in a ring array along the outer wall of the arc plate 5.

[0024] The working principle and beneficial effects of the above technical solution are as follows: During installation, the two semi-circular clamps 1 are first symmetrically installed at a preset height on the pier column 2, and then fastened to the first fastener through the first connecting ear 3. The first connecting ear 3 is provided with an installation hole. The first fastener includes a first bolt and a first nut. The first bolt passes through the installation holes of the two first connecting ears 3. Then, the first nut is installed on the first bolt to complete the fixation, so that the two semi-circular clamps 1 are spliced ​​and fixed to the outside of the pier column 2. Next, the hydraulic rod 9 is activated. The hydraulic rod 9 is fixedly set on the upper surface of the fixing plate 8. The fixing plate 8 is fixedly set on the outer wall of the semi-circular clamp 1. Rod 9 uses existing engineering hydraulic push rods. Activation of hydraulic rod 9 drives support plate 6 upwards. Based on the installation elevation requirements of the precast cap beam 7, the height of support plate 6 is precisely adjusted by the extension length of hydraulic rod 9 until a preset position is reached. This preset position is the installation position of the precast cap beam 7. At this point, the upper surface of support plate 6 can contact the lower surface of the precast cap beam 7. As support plate 6 moves upwards, it drives arc plate 5 to slide upwards along the arc-shaped hole 4 inside the semi-circular clamp 1. Through the sliding cooperation between arc plate 5 and arc-shaped hole 4, the support plate 6 remains horizontal throughout its upward movement, improving its stability. For stability, once the height of the support plate 6 is adjusted to the preset position, the two arc plates 5 are fastened together by the second connecting ears 10 at both ends of the arc plate 5 and the second fasteners. The second connecting ears 10 have second connecting holes. The second fasteners include a second bolt and a second nut. The second bolt passes through the mounting holes of two adjacent second connecting ears 10, and then the second nut is installed on the second bolt to complete the fixation. This, together with the semi-circular clamp 1, bears the vertical force. Finally, the precast cap beam 7 is hoisted onto the upper surface of the support plate 6, and the support plate 6 completes the support work for the precast cap beam 7. During construction, if adjustment is required... The height of the precast cap beam 7 can be adjusted by the extension and retraction of the hydraulic rod 9. During the adjustment process, it is not necessary to disassemble the semi-circular clamp 1. This not only enables rapid adjustment of the height of the support plate 6, improving construction efficiency, but also reduces the number of high-altitude work steps and improves construction safety. A first reinforcing plate 11 is provided on the lower surface of the fixed plate 8, which can enhance the connection between the fixed plate 8 and the outer wall of the semi-circular clamp 1 and improve the reliability of the fixed plate 8. Several second reinforcing plates 12 are provided on the lower surface of the support plate 6. Preferably, there are four second reinforcing plates 12 arranged in a ring array, which can enhance the support performance of the support plate 6.

[0025] Example 2: Based on the above embodiment 1, a semi-circular hole is provided on the side of the support plate 6 near the pier 2, and the diameter of the semi-circular hole is larger than the diameter of the pier 2.

[0026] The working principle and beneficial effects of the above technical solution are as follows: a semi-circular hole is provided on the inner side of the support plate 6. The semi-circular hole can be adapted to the shape of the pier 2, avoiding interference between the support plate 6 and the pier 2. The diameter of the semi-circular hole is larger than the diameter of the pier 2, preventing the edge of the support plate 6 from scratching the surface of the pier 2 during the height adjustment process, avoiding deformation of the support plate 6 due to contact with the pier 2, and extending the service life of the support plate 6.

[0027] Example 3: Based on Example 1 or 2, such as Figures 2-5 As shown, a first anti-slip plate 13 is installed on the side of the semi-circular clamp 1 near the pier 2.

[0028] The working principle and beneficial effects of the above technical solution are as follows: The first anti-slip plate 13 is made of rubber material with a high coefficient of friction. The thickness of the first anti-slip plate 13 is preferably 9mm-13mm. The shape of the first anti-slip plate 13 is adapted to the inner wall of the semi-circular clamp 1. The first anti-slip plate 13 is bonded to the inner wall of the semi-circular clamp 1 by high-strength structural adhesive. The surface of the first anti-slip plate 13 is provided with anti-slip texture. When the semi-circular clamp 1 is fixed to the outside of the pier 2 by the first connecting ear 3 and the first fastener, the inner wall of the first anti-slip plate 13 contacts the outer wall of the pier 2. This not only prevents the semi-circular clamp 1 from directly contacting the pier 2 and damaging the outer wall of the pier 2, but also prevents the support structure from sliding down or rotating laterally along the pier 2, thus improving the stability of the installation of the semi-circular clamp 1.

[0029] Example 4: Based on any one of Examples 1-3, such as Figures 2-5 As shown, a first threaded hole is provided on the upper part of the outer wall of the semi-circular clamp 1. One end of the first threaded hole is connected to the inside of the arc-shaped hole 4. A first screw 14 is provided in the first threaded hole. The first screw 14 is threadedly connected to the first threaded hole. The end of the first screw 14 away from the arc-shaped plate 5 extends to the outside of the first threaded hole and is fixedly provided with a first rotating wheel 15.

[0030] The working principle and beneficial effects of the above technical solution are as follows: After the height of the support plate 6 is adjusted, the first rotating wheel 15 is rotated. The rotation of the first rotating wheel 15 drives the first screw 14 to rotate in the first threaded hole, so that the first screw 14 is screwed into the arc-shaped hole 4 until the end of the first screw 14 is tightly abutted against the outer wall of the arc-shaped plate 5, thereby forming a lateral clamping and positioning of the arc-shaped plate 5, thereby limiting the radial and axial displacement of the arc-shaped plate 5, preventing the arc-shaped plate 5 from shaking in the arc-shaped hole 4, improving the stability of the arc-shaped plate 5, enhancing the anti-overturning ability of the support structure, and enabling the arc-shaped plate 5 to support the support plate 6, further improving the support capacity of the support plate 6; the first rotating wheel 15 is rotated in the opposite direction, so that the first screw 14 is separated from the outer wall of the arc-shaped plate 5, and the height of the support plate 6 can be lowered by retracting the hydraulic rod 9, which is simple to operate.

[0031] Example 5: Based on any one of Examples 1-4, such as Figures 2-5 As shown, a second threaded hole is provided at the upper position of the arc plate 5. The second threaded hole penetrates the arc plate 5. A second screw 16 is provided in the second threaded hole. The second screw 16 is threadedly connected to the second threaded hole. The end of the second screw 16 away from the pier 2 extends to the outside of the second threaded hole and is provided with a second rotating wheel 17. The second screw 16 extends to the inner side of the arc plate 5 near the pier 2 and is fitted with a second anti-slip plate 18.

[0032] The working principle and beneficial effects of the above technical solution are as follows: Initially, the second anti-slip plate 18 is not in contact with the outer wall of the pier 2. After the height of the support plate 6 is adjusted, the second rotating wheel 17 is rotated first. The rotation of the second rotating wheel 17 drives the second screw 16 to rotate in the second threaded hole. The second screw 16 drives the second anti-slip plate 18 to move closer to the pier 2. The second anti-slip plate 18 is made of wear-resistant rubber. When the second anti-slip plate 18 abuts against the outer wall of the pier 2, the rotation of the second rotating wheel 17 is stopped. Through the contact between the second anti-slip plate 18 and the pier 2, the second connecting ear 10 and the second fastener can lock the arc plate 5 and the pier 2. To prevent the arc-shaped plate 5 from sliding down along the arc-shaped hole 4, the second anti-slip plate 18 abuts against the pier column 2, based on the lateral positioning of the first screw 14, which can further restrict the vertical displacement of the arc-shaped plate 5. Even if the hydraulic rod 9 has a slight tendency to settle, the arc-shaped plate 5 can form a reverse constraint through the friction between the second anti-slip plate 18 and the outer wall of the pier column 2, reducing the degree of settlement of the support plate 6 and further improving the stability of the support plate 6. Rotating the second rotating wheel 17 in the opposite direction drives the second screw 16 to rotate, which can separate the second anti-slip plate 18 from the outer wall of the pier column 2. At this time, the height of the support plate 6 can be adjusted by the hydraulic rod 9, ensuring construction efficiency.
