Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a device for protecting the edge of a temporary opening on a bridge top plate. Background Art

[0002] In bridge construction, in order to improve the bearing capacity and bending resistance of the bridge and meet construction requirements, box girder structures are often used in bridge construction. The box girder is a beam-type component with a hollow cross-section. Its upper structure consists of a top plate, a bottom plate and webs on both sides. These components together form one or more closed or semi-closed spaces, namely "boxes". The independent spaces separated by the webs in the box girder section are box chambers. Box girders have been widely used in bridge engineering due to their good stress-bearing performance and construction convenience.

[0003] During the construction of a bridge, it is often necessary to reserve an opening on the top plate when pouring to facilitate subsequent construction. Steel bars will extend from the edge of the reserved opening. In order to ensure the safety of people going up and down, the steel bars extending from the opening will be set upwards. Edge protection is required around the reserved opening to protect the safety of people.

[0004] At present, traditional edge protection of openings generally adopts the method of setting up edge guardrails or laying formwork covers. When setting up edge guardrails, it is often necessary to drive expansion bolts into the bridge deck, causing damage to the concrete structure. At the same time, the cost of edge protection is high and it is inconvenient to install and remove. When using formwork covers, there are upward steel bars at the opening, so traditional formwork covers can only be placed on the steel bars, which is unstable and easy to fall. In addition, the bridge deck needs to be watered for maintenance, which can easily cause damage to the formwork covers. In addition, these two methods are not convenient for construction workers to enter and exit the box room. Utility Model Content

[0005] In order to solve the problem of personnel entry and exit in the background technology, the present application provides a temporary opening edge protection device for the bridge top plate.

[0006] This application provides a temporary opening edge protection device for a bridge top plate, which adopts the following technical solutions:

[0007] A device for protecting the edges of temporary openings on a bridge top plate comprises a protective base plate arranged on the bridge opening, the protective base plate being provided with an inlet and outlet for facilitating entry and exit of personnel and cooperating with the bridge opening, side plates being arranged upwardly around the protective base plate, the side plates being provided with an escape space for evading steel bars, and a cover plate for closing the escape space being movably connected to a side of the side plate away from the base plate.

[0008] By adopting the above technical solution, construction workers can easily enter and exit the entrance using the movable cover plates. The side plates effectively enclose an avoidance space for steel bars, making the installation of protective devices more convenient. At the same time, the side plates and cover plates can effectively prevent debris from falling into the hole, thereby improving construction safety.

[0009] Preferably, universal wheels are provided at the bottom of the side panels.

[0010] By adopting the above technical solution, it is easy to move and can be transferred to other sections of the bridge opening protection at any time.

[0011] Preferably, the universal wheel is rotatably connected to the base plate, and the universal wheel can be rotated outward by 180°, at which time the protective base plate abuts against the bridge deck.

[0012] By adopting the above technical solution, the universal wheel is rotated 180° so that the protective bottom plate contacts the bridge deck, which allows the device to be placed more stably on the bridge deck and further improves safety by completely sealing the opening on the bridge.

[0013] Preferably, the cover is provided with a handle for convenient opening and closing of the cover.

[0014] By adopting the above technical solution, the design of the handle enables construction workers to easily open and close the cover, thereby improving operational efficiency.

[0015] Preferably, the cover plate is rotatably connected to the side plate.

[0016] By adopting the above technical solution, a flip-type opening and closing is achieved, which is convenient for construction workers to enter and exit. The flip-type design allows the cover to be easily opened and closed.

[0017] Preferably, sliding members are horizontally provided on the two side panels that are arranged opposite to each other, and the cover plate forms a sliding fit with the sliding members.

[0018] By adopting the above technical solution and setting the sliding member, a push-opening and closing method is provided for the cover, so that the cover can be slid open or closed as needed.

[0019] Preferably, the cover plate is also provided with an observation window for observing the interior of the chamber.

[0020] By adopting the above technical solution, the design of the observation window enables construction workers to observe the situation inside the box at any time, thereby improving the convenience and safety of construction.

[0021] Preferably, the side panels are further provided with ventilation holes for ventilation.

[0022] By adopting the above technical solution, the design of the ventilation holes helps to improve the construction environment and enhance the comfort of construction workers.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up entrances and exits and covers, it is convenient for construction workers to enter and exit the hole, and at the same time prevents people or debris from falling in, thereby improving construction safety;

[0025] 2. The handle, flip-top design, and sliding part design provide two ways to open and close the cover, and you can choose the appropriate method to use. The handle design makes the cover easier to operate when flipping or pushing and pulling. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0031] Example 1

[0032] An embodiment of the present application discloses a device for protecting the edge of a temporary opening in a bridge top plate.

[0033] Reference Figure 1 The top of the bridge is provided with a plurality of side panels 3, each of which is provided with a plurality of support members 3, and the support members 3 are provided with a plurality of support members 3.

[0034] Reference Figure 1 and Figure 2 Since the structures and connection methods of the four universal wheels 5 are the same, one of them is taken as an example for explanation.

[0035] Reference Figure 1 and Figure 2 The rotatable connection between the side panel 3 and the universal wheel 5 is provided with an abutment plate 51. The abutment plate 51 and the side panel 3 are rotated by a rotating hinge, and the universal wheel 5 is rotatably connected to the abutment plate 51. When in use, the abutment plate 51 forms an abutment fit with the protective bottom plate 1. At this time, the universal wheel 5 can act as a moving wheel. When the universal wheel 5 rotates outward 180°, the abutment plate 51 will release the abutment relationship with the protective bottom plate 1 and detach from the protective bottom plate 1. At this time, the protective bottom plate 1 can abut against the bridge deck, which increases the stability and safety of the device.

[0036] Reference Figure 1 and Figure 2 When the protective device needs to be transferred to other sections of the bridge opening for protection, the protective device is lifted onto the flat bridge surface, the universal wheel 5 is lowered, and the abutment plate 51 is abutted against the protective bottom plate 1 by relying on the protective device's own gravity, and the protective device is pushed to other bridge surfaces.

[0037] Reference Figure 1 The cover plate 4 is rotatably connected to the side of the side plate 3 away from the protective bottom plate 1 through a rotating shaft to achieve flexible opening and closing. In this embodiment, two cover plates 4 are set, and the two cover plates 4 are arranged opposite to each other to achieve flip-up opening and closing. Handles 42 are provided on the upper and lower sides of the cover plate 4. The setting of the handles 42 makes it convenient for workers to open and close the cover plate 4.

[0038] Reference Figure 1 An observation window 41 is also provided on the cover 4. The observation window 41 can be a small window made of transparent material, allowing construction workers to observe the internal situation of the box without opening the cover 4. Such a design can help construction workers understand the internal work progress or check possible problems without disturbing the internal environment of the box.

[0039] Reference Figure 1 The side panels 3 are also provided with a plurality of ventilation holes 31, which allow air to circulate, ensuring that the air inside the box is fresh and providing a more comfortable working environment for the construction workers. The size and number of the ventilation holes 31 can be designed according to actual needs to ensure sufficient air circulation.

[0040] The implementation principle of the embodiment of the present application is as follows: construction workers can easily open the flip-type cover 4 through the handle 42 to enter the hole for easy entry and exit; after completing the entry and exit, the construction workers only need to close the cover 4 to re-close the hole to ensure safety; at the same time, the universal wheel 5 with a brake allows the device to be easily moved to the required position and fixed, thereby improving construction efficiency and safety.

[0041] Example 2

[0042] The difference between the second embodiment and the first embodiment is that:

[0043] Reference Figure 3 The cover plate 4 is configured to be pull-out, and sliding members 6 are horizontally arranged on the outer walls of the two side plates 3 that are arranged opposite to each other. The cover plate 4 and the sliding members 6 form a sliding fit. In the embodiment of the present application, the sliding member 6 is configured to be a triangular steel, which is fixedly connected to the outer wall of the side plate 3. The upper surface of the triangular steel is at the same height as the upper end of the side plate 3, and the cover plate 4 and the triangular steel form a sliding fit.

[0044] The working principle of this embodiment of the application is as follows: Construction workers can easily pull the pull-out cover plate 4 from the triangular steel platform using handle 42, thereby opening the hole and facilitating entry and exit. After entering and exiting, construction workers simply push the cover plate 4 back into place to re-close the hole and ensure safety. Furthermore, universal wheels 5 with brakes allow the device to be easily moved to the desired location and fixed, improving construction efficiency and safety.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
