Description

Technical Field

[0001] This utility model relates to the technical field of safety protection equipment, specifically to an integrated device for edge protection and maintenance of bridge cap beam formwork. Background Technology

[0002] Fall protection nets, as essential safety equipment for high-altitude operations, are widely used on various construction sites to effectively prevent injuries from falling personnel and objects. During elevated bridge construction, T-beams, as the main supporting components of the bridge, are the first to be constructed. Typically, fall protection nets are installed on top of the T-beams after hoisting and during the installation of column formwork. T-beams consist of piers and cap beams. Furthermore, in current construction processes, especially during cap beam construction, continuous curing of the cap beams is required after pouring and before the formwork is removed. Therefore, it is necessary to avoid the impact of high temperatures from the sun on curing. The specific method is to cover the cap beams with a curing cover or membrane. However, adding a curing cover or membrane not only increases production costs but also consumes time and labor, affecting the construction progress. Utility Model Content

It can combine construction protection and cap beam maintenance, which can not only save construction time, but also effectively reduce construction costs.

[0021] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0022] See Figures 1-5 In one embodiment of this utility model, a bridge cap beam formwork edge protection and maintenance integrated device includes: a protective component 1 and multiple flip seats 2. The multiple flip seats 2 are all located at the lower end of the protective component 1. In implementation, the flip seats 2 are fixedly installed at the edge of the top of the cap beam formwork (not shown in the figure). The protective component 1 can be flipped up and down relative to the cap beam through the flip seats 2. That is, when construction protection is required, the protective component 1 is fixed on the upper side of the cap beam, which strengthens the safety protection during the cap beam pouring construction process and ensures the safety of workers working at height. When the cap beam needs to be maintained, the protective component 1 covers the side of the cap beam by falling naturally, which minimizes the impact of direct sunlight and exposure on the cap beam, improves the initial setting quality of the beam, and reduces the thermal shrinkage crack rate of the beam, thus achieving the purpose of maintenance and ultimately improving the quality of the project.

[0023] Specifically, the protective component 1 consists of a frame and a protective net 13. The frame includes vertical bars 11 arranged longitudinally and horizontal bars 12 arranged laterally. The protective net 13 is located inside the frame. In this embodiment, the protective net 13 not only plays a role in safety protection but also in maintenance. Based on this, the protective net 13 is composed of a rigid metal mesh and a soft shade net superimposed and bonded together. It can be understood that the metal mesh and the shade net are of the same size.

[0024] In one embodiment, the mesh count of the shade net can be selected according to actual needs and environment. For example, in low-temperature environments, a 40-mesh or 60-mesh shade net can be used, while in high-temperature environments, an 80-mesh or 100-mesh shade net can be used to cope with strong direct sunlight.

[0025] In one embodiment, the metal mesh can be a perforated metal mesh with closely spaced openings that can block and reflect most of the sunlight.

[0026] To achieve the purpose of flipping up and down, the flipping seat 2 includes a fixed plate 21, two support arms 22, a rotating shaft 23, a connecting rod 24, and a connecting seat 25. The two support arms 22 are fixedly mounted on the front end of the fixed plate 21 and are arranged along the left and right directions of the fixed plate 21. The rotating shaft 23 is rotatably mounted between the support arms 22, and the axis of the rotating shaft 23 is parallel to the main end face of the fixed plate 21. It can be seen that the length direction of the rotating shaft 23 is consistent with the length direction of the fixed plate 21. One end of the connecting rod 24 is fixedly connected to the outer periphery of the rotating shaft 23 and the connecting rod 24 is located between the two support arms 22. The connecting seat 25 is fixedly mounted on the other end of the connecting rod 24. Under the action of external force, the connecting seat 25 can be flipped up and down relative to the fixed plate 21 through the rotating shaft 23. In the initial state, the main end face of the connecting seat 25 is flush with the upper end face of the fixed plate 21. In this embodiment, after installation, the connecting seat 25 is fixedly connected to the vertical rod 11 of the frame by screws. After connection, the vertical rod 11 is perpendicular to the main end face of the connecting seat 25. During implementation, the fixing plate 21 is fixed to the structural component at the top of the cap beam by bolts.

[0027] In one embodiment, the flip seat 2 further includes a pin 27. The connecting seat 25 and the fixing plate 21 are both provided with corresponding through holes. When construction protection is required, the protective component 1 needs to be located on the upper side of the flip seat 2 and fixed. At this time, the main end face of the connecting seat 25 is flush with the upper end face of the fixing plate 21. By inserting the pin 27 into the through holes on the connecting seat 25 and the fixing plate 21, the connecting seat 25 and the fixing plate 21 are fixed relative to each other, so that the protective component 1 is kept in a vertical position to achieve the purpose of protection.

[0028] In one embodiment, the flipping seat 2 further includes two auxiliary wheels 26, both of which are sleeved on the rotating shaft 23 and located between the two support arms 22. The outer edge of the auxiliary wheel 26 slides against the fixed plate 21. The auxiliary wheel 26 can share the load-bearing pressure of the rotating shaft 23, making the stability of the flipping seat 2 more reliable.

[0029] Please see Figure 5 This is the usage state of the integrated protection and maintenance device. During use, multiple integrated protection and maintenance devices can be set according to the length of the cap beam template 3. The multiple integrated protection and maintenance devices are distributed at intervals to ensure sufficient coverage of the outer perimeter of the cap beam template 3. It should be noted that the two cap beam templates 3 facing each other are connected and fixed by tie bolts.

[0030] This technical solution, by movably placing the protective component on the top edge of the cap beam formwork, strengthens safety protection during the cap beam pouring process and ensures the safety of workers operating at heights when construction protection is required. When the cap beam needs curing, the protective component is flipped over after pouring and before the formwork is removed, allowing it to fall naturally and cover the side of the cap beam, minimizing the impact of direct sunlight and exposure. This method is convenient and quick. By combining construction protection and cap beam curing, not only is construction time saved, but construction costs are also effectively reduced.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
