Description

Technical Field

[0001] This utility model relates to the field of girder clamp construction technology, and in particular to a safe operating platform for girder clamp construction. Background Technology

[0002] The cap beam clamp is an important temporary support structure for bridge cap beam construction. Made of high-strength steel, it consists of two semi-circular clamps connected by high-strength bolts, securing the bridge pier column. This allows the pier column to bear the construction load of the cap beam, avoiding the drawbacks of traditional ground support methods. During implementation, the pier column parameters are accurately measured to customize the clamp. A crane is used to lift the semi-circular clamps to their positions around the pier column. The bolt tightening torque is adjusted to ensure a tight fit between the clamp and the pier column, relying on friction to bear the load. After installation, the clamp's levelness, verticality, and bolt tightness are rigorously checked to ensure a secure and stable installation, providing reliable support for the cap beam construction.

[0003] The construction of the cap beam involves a lot of high-altitude work and poses significant safety risks. Therefore, it is essential to build a safe operating platform. The safe operating platform for the cap beam clamp construction is built based on the clamps. The platform frame is welded with steel sections and reliably connected to the clamps to ensure overall stability.

[0004] Patent document CN212077651U discloses a cap beam clamp installation device, including a base, a support seat, and lifting rings. The base has a through hole adapted to the outer periphery of the cap beam clamp, the support seat is disposed on the outer periphery of the base, and the lifting rings are disposed on the top of the support seat, with at least two lifting rings. The clamp can be placed on the base, and the cap beam clamp installation device can be lifted and installed onto the corresponding position of the pier using a lifting device via the lifting rings. A person can stand on the base to install the clamp on the base onto the pier, and then rotate the cap beam clamp installation device to align the clamp with the installation space before lifting and removing the device. This utility model solves the problem of inconvenient clamp installation, provides workers with a safe and reliable operating platform, and ensures the safety of clamp installation.

[0005] In the prior art of the aforementioned patent, most operating platforms are of a fixed height. After the operating platform is set up, in subsequent work, a concrete pouring mold needs to be installed between two base columns, and then concrete is poured into the mold. Before the concrete is demolded, it needs to be watered and cured. The cap beam is relatively high, so workers need to stand at a high position to cure the concrete. The original operating platform cannot meet the needs of subsequent work, causing inconvenience to the subsequent curing process. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7A safety operating platform for beam capping construction includes two base columns 1, with a clamp body 102 fixedly installed on each of the two base columns 1. An operating platform body 2 is fixedly installed on the top of each of the two base columns 1, and the operating platform body 2 is fixedly connected to the clamp body 102. Two side railings 3 and a main railing 4 are provided on the operating platform body 2. A rotating shaft 6 is rotatably installed on the top of each of the two main railings 4. A protective plate 7 and a bearing plate 8 are fixedly installed on each of the two rotating shafts 6, and the protective plate 7 and the bearing plate 8 are vertically arranged. The inner side of the main fence 4 is provided with an overlapping component; the specific overlapping and connection methods of the operating platform body 2 and the clamp body 102 are all existing technologies, so they will not be described in detail. When workers need to cure concrete from a height, the bearing plate 8 can be rotated into the interior of the operating platform body 2 by flipping the rotating shaft 6. The bearing plate 8 is limited by the overlapping block 12. The protective plate 7 replaces the original position of the bearing plate 8, thereby protecting the bearing plate 8. The height of the protective plate 7 meets the normal safety requirements and can prevent workers from falling.

[0027] As a preferred technical solution in this embodiment, one of the side fences 3 is provided with a safety door 5; the safety door 5 can be opened and locked normally, and can facilitate the staff to enter the operating platform body 2 through the externally set ladder cage.

[0028] As a preferred technical solution in this embodiment, overlapping plates 9 are fixedly installed on the outer sides of both main fences 4. The two protective plates 7 are initially overlapped at the top of the overlapping plates 9. The two bearing plates 8 are initially positioned above the main fences 4 and are used to protect the operating platform body 2. In the initial state, the protective plates 7 are horizontal outside the operating platform body 2, and the bearing plates 8 are vertical for protection. At this time, the internal space of the operating platform body 2 is not affected by the bearing plates 8 and the protective plates 7, which can meet the normal operation requirements.

[0029] As a preferred technical solution in this embodiment, the overlapping component includes a sliding groove 10 formed on the inner wall of the two main fences 4. A slider 11 is slidably installed inside the sliding groove 10, and an overlapping block 12 is fixedly installed on the slider 11. The overlapping block 12 is initially positioned at both ends of the sliding groove 10 to prevent it from affecting the operation. When it is necessary to flip the bearing plate 8, the overlapping block 12 is slid to the middle position of the sliding groove 10. Both the overlapping block 12 and the slider 11 are high-strength die-cast cylinder parts, which can meet the weight of the bearing plate 8 and the workers. The bearing plate 8 is relatively heavy, and there is no risk of tipping over when the workers stand on it. No specific fixing mechanism is required to fix it; it can be overlapped on the overlapping block 12. If safety is to be ensured, it can be bound to the main fence 4 with steel cables.

[0030] As a preferred technical solution in this embodiment, the slider 11 and the slide groove 10 are adapted to each other. The width of the side of the slider 11 near the inner side of the slide groove 10 is greater than the width of the side of the slider 11 near the outer side of the slide groove 10. The cross-section of the slider 11 is an isosceles trapezoid. The opening of the slide groove 10 is adapted to the slider 11. The slider 11 and the slide groove 10 adopt a mortise and tenon joint-like connection, which can enhance the stability and structural strength of the connection between the slider 11 and the slide groove 10. Lubricating oil needs to be added between the slider 11 and the slide groove 10 regularly to facilitate the smooth sliding of the slider 11.

[0031] As a preferred technical solution of this embodiment, the top of the bearing plate 8 is provided with a plurality of drainage holes 13, and the top of the bearing plate 8 is provided with an anti-slip layer 14; when standing on the bearing plate 8 to cure the concrete by spraying water, the leaked water leaks out through the drainage holes 13, and the anti-slip layer 14 can further increase the anti-slip performance and safety.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
