Description

Technical Field

[0001] This utility model relates to the field of climbing formwork technology, specifically a hydraulic climbing formwork for bridges. Background Technology

[0002] Bridge construction often involves high-altitude operations such as high piers and continuous beams. Climbing scaffolds can be raised and lowered synchronously with the construction progress, providing a stable and safe operating platform for workers. This avoids the tediousness and risks of repeatedly setting up temporary scaffolds. Compared with traditional scaffolds, climbing scaffolds can precisely fit the shape of bridge piers, beams and other structures, reducing material waste. At the same time, they do not occupy ground space and are suitable for complex site environments in bridge construction.

[0003] The hydraulic climbing formwork installation first involves pouring the foundation section at the bottom of the pier and pre-embedding the attachment supports. Then, the main frame of the climbing formwork, hydraulic jacks, and the formwork system are assembled. After calibrating the verticality of the formwork, it is fixed to complete the initial installation. During operation, the concrete of the current section of the pier is poured first. After the strength reaches the standard, the hydraulic system is activated to make the climbing formwork climb up with the attachment supports. Once in place, the climbing formwork is locked. Then, the formwork is driven to rise synchronously with the climbing formwork to the next construction section. The positioning is calibrated again, and the concrete pouring and climbing are repeated until the pier construction is completed.

[0004] In existing climbing formwork devices, a ladder is usually set between the base and the operating platform. In order to reduce the weight by reducing the area of ​​the support plate in the middle of the ladder while ensuring use, the reduced support area will reduce the force of contact during use, thus reducing its practicality.

[0005] Therefore, a hydraulic climbing formwork for bridges is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A hydraulic climbing formwork for bridges, comprising a base, an operating platform on the top of the base; a ladder installed between the operating platform and the base; multiple support plates fixedly connected inside the ladder; extension plates rotatably connected to the ends of the support plates; the support plates and extension plates connected by torsion springs; a first magnet fixedly connected to the side wall of the extension plate; multiple handrails fixedly connected to the surface of the ladder; the handrails located on both sides of the ladder; a hydraulic system provided in the middle of the operating platform; by increasing the support area of ​​the support plates by adding extension plates, the contact area between the operator's feet and the support plates can be increased when climbing, making it more stable during climbing. At the same time, when not in use, the support plates and extension plates can be quickly folded together by rotating the extension plates to restore their original shape, thereby reducing the space occupied during storage.

[0008] Preferably, a pair of baffles are slidably connected to the bottom of the operating platform; a pair of second magnets are fixed to the side wall of the baffles; by adding baffles, the area above the operating platform that is not equipped with a protective net can be blocked, thereby reducing the impact of falling materials on the operating platform plane, thus protecting the operating platform and increasing the interception of falling materials.

[0009] Preferably, multiple elastic ropes are fixedly connected inside the handrail; a pair of fixed rods are fixedly connected in the middle of the ladder; the fixed rods and elastic ropes are arranged in an alternating manner; by adding elastic ropes and fixed rods, the convenience of climbing can be increased by the cooperation of elastic ropes and fixed rods, allowing for more contact points to be selected, thereby quickly contacting the force for climbing.

[0010] Preferably, the ladder sidewall is fixed with multiple hooks; the hooks are located on the inner side of the ladder; by adding hooks, tools can be stored in the middle position between the base and the operating platform, so that the operator can directly reach out and touch the tools, thereby increasing the convenience of access.

[0011] Preferably, a pair of limiting plates are fixed to the side wall of the extension plate; a limiting groove is formed in the middle of the limiting plate; by adding the limiting groove, the foot can be guided by the limiting groove when the foot is placed on the support plate and the extension plate, and at the same time the limiting groove can prevent the foot from extending too far, thereby increasing the contact balance of the foot on the support plate and the extension plate.

[0012] Preferably, anti-slip pads are fixed to the surfaces of both the support plate and the extension plate; the anti-slip pads are arranged oppositely on both sides of the support plate and the extension plate; by adding anti-slip pads, anti-slip can be increased when the feet and the support plate and the extension plate come into contact, so as to increase more traction points for the feet when climbing, and the opposite arrangement of the anti-slip pads can adapt to the left and right feet when the feet come into contact.

[0013] The advantages of this utility model are:

[0014] 1. The hydraulic climbing formwork for bridges described in this utility model increases the support area of ​​the support plate by adding an extension plate, which increases the contact area between the operator's feet and the support plate when climbing, making it more stable during climbing. At the same time, when not in use, the support plate and the extension plate can be rotated to restore the formwork, and the support plate and the extension plate can be quickly attached together for folding, thereby reducing the space occupied during storage.

[0015] 2. The hydraulic climbing formwork for bridges described in this utility model can block areas on the upper part of the operating platform that are not equipped with protective netting by adding baffles, thereby reducing the impact of falling materials on the operating platform plane and protecting the operating platform, and increasing the interception of falling materials.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6As shown in the embodiment of this utility model, a bridge hydraulic climbing formwork includes a base 1, with an operating platform 11 on the top of the base 1; a climbing ladder 12 is installed between the operating platform 11 and the base 1; multiple support plates 13 are fixedly connected inside the climbing ladder 12; extension plates 14 are rotatably connected to the ends of the support plates 13; the support plates 13 and the extension plates 14 are connected by torsion springs; a first magnet 15 is fixedly connected to the side wall of the extension plate 14; multiple handrails 16 are fixedly connected to the surface of the climbing ladder 12; the handrails 16 are located on both sides of the climbing ladder 12; the... A hydraulic system 17 is installed in the middle of the operating platform 11. During operation, the base 1 and the operating platform 11 are hoisted to the beam / column and connected via existing embedded parts and wall-mounted devices. After connection, the hydraulic system 17 controls the bidirectional drive component to move the entire structure along the guide rail, thus achieving elevation. When using the hydraulic system 17, an operator must supervise the process. The operator must first move from the base 1 to the operating platform 11 via the ladder 12. During movement, the extension plate 14 is rotated to extend the extension plate. The plate 14 rotates and opens, widening the support plate 13. After widening, the first magnet 15 gradually comes into contact with the support plate 13, attracting it and thus fixing the extension plate 14. After fixing, it can contact the armrest 16 for gripping. After gripping, it can gradually climb upwards. During climbing, the increased support area formed by the support plate 13 and the extension plate 14 increases the contact area, thereby increasing stability. When not in use for a long time, the extension plate 14 can be rotated closer to the support plate 13. This separates the first magnet 15 from the support plate 13. After separation, the extension plate 14 will return to its original position due to the force of the torsion spring and move closer to the support plate 13. By increasing the support area of ​​the support plate 13 by adding the extension plate 14, the contact area between the operator's feet and the support plate 13 can be increased when climbing, making it more stable during climbing. At the same time, when not in use, the extension plate 14 can be rotated to contact the support plate 13 and return to its original position, and the support plate 13 and the extension plate 14 can be quickly attached together for folding, thereby reducing the space occupied during storage.

[0027] like Figures 1 to 5As shown, a pair of baffles 2 are slidably connected to the bottom of the operating platform 11; a pair of second magnets 21 are fixed to the side wall of the baffles 2; during operation, when the operator controls the hydraulic system 17 on the operating platform 11, the pair of baffles 2 can be pushed outward, thereby gradually extending to the end of the operating platform 11. After extending, they can provide a barrier for the operating platform 11, thereby blocking falling materials from the outside and reducing the amount of falling materials entering the operating platform 11. When the operating platform 11 is pushed to the end, the second magnets 21 will magnetically attract the frame, fixing it in place; by adding baffles 2, the area on the upper part of the operating platform 11 without a protective net can be blocked, reducing the impact of falling materials on the plane of the operating platform 11, thereby protecting the operating platform 11 and increasing the interception of falling materials.

[0028] like Figures 2 to 4 As shown, multiple elastic ropes 3 are fixedly connected inside the handrail 16; a pair of fixed rods 31 are fixedly connected to the middle of the ladder 12; the fixed rods 31 and the elastic ropes 3 are arranged in an alternating manner; during operation, the handrail can come into contact with the elastic ropes 3 when climbing, and the elastic ropes 3 will form a pulling force with the hand after contact, making it more stable when climbing. At the same time, the elastic ropes 3 and the fixed rods 31 are arranged in an alternating manner to form multiple force points, so that there are more contact positions when climbing; by adding elastic ropes 3 and fixed rods 31, the climbing is more convenient through the cooperation of elastic ropes 3 and fixed rods 31, so that there are more contact positions to choose from, thereby quickly contacting the force for climbing.

[0029] like Figure 3 As shown, the ladder 12 has multiple hooks 4 fixed to its side wall; the hooks 4 are located on the inner side of the ladder 12; during operation, since the base 1 needs to gradually rise during use, the tools needed can be lifted up by the hooks 4 and placed there so that they are not placed on the ground of the base 1, thereby saving space of the base 1; by adding hooks 4, the tools can be stored in the middle position between the base 1 and the operating platform 11, so that the operator can directly reach out and touch the tools, thereby increasing the convenience of picking them up.

[0030] like Figures 3 to 4As shown, a pair of limiting plates 5 are fixedly connected to the side wall of the extension plate 14; a limiting groove 51 is formed in the middle of the limiting plate 5; during operation, when the foot and the support plate 13 are in contact with the extension plate 14, the end of the foot can move directly into the limiting groove 51, thereby positioning the foot between the support plate 13 and the extension plate 14 when in contact with the support plate 13 and the extension plate 14, thus quickly positioning the foot on the support plate 13 and the extension plate 14 and increasing the contact between them; by adding the limiting groove 51, the foot can be guided by the limiting groove 51 when placed on the support plate 13 and the extension plate 14, and at the same time, the limiting groove 51 can prevent the foot from extending too far, thereby increasing the contact balance of the foot on the support plate 13 and the extension plate 14.

[0031] like Figures 3 to 4 As shown, anti-slip pads 6 are fixed to the surfaces of both the support plate 13 and the extension plate 14. The anti-slip pads 6 are arranged oppositely on both sides of the support plate 13 and the extension plate 14. During operation, when the foot contacts the support plate 13 and the extension plate 14, the anti-slip pads 6 are squeezed by weight. During the compression, the anti-slip pads 6 will expand and contract, increasing the contact area with the foot and thus increasing the friction between them. This increases friction and reduces slippage when the support plate 13 and the extension plate 14 are under force. By adding anti-slip pads 6, anti-slip can be increased when the foot contacts the support plate 13 and the extension plate 14, providing more points of force for the foot during climbing. At the same time, the opposite arrangement of the anti-slip pads 6 can adapt to the left and right feet when the foot contacts them.

[0032] Working principle: During use, the base 1 and operating platform 11 are hoisted to the side of the beam and column and connected through existing embedded parts and wall-mounting devices. After connection, the hydraulic system 17 controls the bidirectional drive component to move the entire assembly on the guide rail, thereby climbing. When using the hydraulic system 17, an operator needs to supervise. When moving, the operator must first move from the base 1 to the operating platform 11 via the ladder 12. During movement, the extension plate 14 is rotated to open it, widening the support plate 13. After widening, the first magnet 15 gradually contacts the support plate 13, attracting it and thus lifting it. The extension plate 14 is fixed in place, and after fixing, it can contact the handrail 16 for gripping. After gripping, it can be gradually raised. During the raising, the support area formed by the support plate 13 and the extension plate 14 increases, which increases the contact area and thus increases stability. When not in use for a long time, the extension plate 14 can be rotated to move closer to the support plate 13, thereby separating the first magnet 15 from the support plate 13. After separation, the extension plate 14 will return to its original position due to the force of the torsion spring. When the operator operates the hydraulic system 17 on the operating platform 11, a pair of baffles 2 can be pushed outward, thereby gradually extending out of the end of the operating platform 11. The operating platform 11 can be blocked by external objects, reducing the amount of material falling onto it. When the operating platform 11 is pushed to the end, the second magnet 21 will magnetically attract the frame, fixing it in place. During climbing, it can contact the elastic rope 3, which will create a pulling force between the rope and the hand, making it more stable during climbing. The elastic rope 3 and the fixing rod 31 intersect to form multiple force points, increasing the number of contact points during climbing. Since the base 1 needs to gradually rise during use, tools can be hoisted using the hook 4 for placement. The foot is positioned on the ground of the base 1, thus saving space in the base 1; when the foot contacts the support plate 13 and the extension plate 14, the end of the foot can move directly into the limiting groove 51, thereby positioning the foot between the support plate 13 and the extension plate 14 when in contact with the support plate 13 and the extension plate 14, thereby quickly positioning the foot on the support plate 13 and the extension plate 14 and increasing the contact between them; when the foot contacts the support plate 13 and the extension plate 14, the anti-slip pad 6 will be squeezed by the weight, and the anti-slip pad 6 will expand and contract during the compression, thereby increasing the contact area with the foot and increasing the friction between them, thereby increasing friction and reducing slippage when the support plate 13 and the extension plate 14 are under force.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
