Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a splicing fence for bridge construction. Background Technology

[0002] During the construction of bridges, it is necessary to install fences in certain areas. This not only serves as a warning but also prevents some people and vehicles from passing through.

[0003] Patent CN222847932U discloses a safety fence, belonging to the field of public safety facilities technology. The bottom of the vertical barrier is fixed to the center of an anti-push-over seat, with two parts of the anti-push-over seat on either side of the vertical barrier. The vertical barrier is connected to a connecting ring via a hook with a bent head. The frame of the anti-push-over seat can be trapezoidal or triangular, with the larger end facing the crowd. Although this fence is manufactured in sections, transportation, installation, and dismantling are quick and convenient, suitable for various linear layouts. When a person steps on one part of the anti-push-over seat, the fence cannot be pushed down or disassembled because there is another part of the anti-push-over seat on the other side. It can be freely turned and installed, making it a safe and reliable safety isolation product that saves a significant amount of law enforcement and maintenance personnel. It is an important isolation facility for safety isolation, security, and explosion prevention in various large-scale event sites, tourist attractions, accident scenes, and densely populated places such as train stations and airports. However, some drawbacks still exist:

[0004] Whether it's a fence or a frame, the overall structure is quite large, making it inconvenient to transport and store. Moreover, the large size of the fence and frame makes installation and dismantling difficult due to their weight. In particular, since the fence and frame are fixed structures, they cannot be flexibly added or reduced according to the length requirements of the construction. Utility Model Content

[0005] The purpose of this utility model is to provide a splicing fence for bridge construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a splicing fence for bridge construction, including a base and a connecting seat fixedly welded to the upper end of the base.

[0026] Example 1

[0027] like Figure 1-3As shown, this utility model provides a technical solution: including a base 1 and a connecting seat 2 fixedly welded to the upper end of the base 1. The connecting seat 2 is provided in two sets, and a connecting groove 7 is opened at the upper end of both sets of connecting seats 2. Both ends of the connecting groove 7 are open structures. A first protective plate 3 is slidably embedded in the connecting groove 7. A fixing bolt 8 threaded through the connecting seat 2 is used to fix the first protective plate 3.

[0028] The connecting seat 2 is a hollow trapezoidal structure, and a groove with an inwardly concave structure is opened in the middle of the bottom end of the connecting seat 2.

[0029] The bottom surface of the connecting seat 2 is welded with anti-slip strips 9, and the anti-slip strips 9 are arranged on the front and back sides of the groove.

[0030] In this embodiment, the protective plate can be detached from the connecting seat. After disassembly, each component is small in size and dispersed in weight, which solves the problems of inconvenient transportation and difficult storage caused by the large overall size and heavy weight of traditional fences, and greatly reduces the transportation space occupation rate and storage cost.

[0031] Example 2

[0032] like Figure 1-5 As shown, this utility model provides a technical solution: including a first protective plate 3 and a second protective plate 6, the inner ends of the two first protective plates 3 are provided with a second protective plate 6, the second protective plate 6 is provided in multiple sets, the upper and lower inner ends of the first protective plate 3 and the second protective plate 6 are provided with mounting grooves 10, and a connecting plate 11 is slidably embedded in the mounting grooves 10.

[0033] The first protective plate 3 and the second protective plate 6 are spliced ​​together by the connecting plate 11, and both the first protective plate 3 and the second protective plate 6 are fixedly connected to the connecting plate 11 by bolts 5.

[0034] The tops of the first protective plate 3 and the second protective plate 6 are arc-shaped, and their inner end faces are fitted together.

[0035] The first protective plate 3 and the second protective plate 6 have the same area, and both have multiple equally spaced strip grooves 4 in the middle.

[0036] The top and bottom ends of the strip groove 4 are closed structures, while the front and rear ends of the strip groove 4 are open structures.

[0037] In this embodiment, both protective panels are modularly spliced ​​through connecting plates, requiring no complicated tools and with a simple operation process. Compared with traditional large fences, it effectively reduces the manpower burden during installation and disassembly, improves construction efficiency, and allows for flexible increase in the number of second protective panels according to the protection length requirements of on-site construction, adapting to protection areas of different spans.

[0038] Working principle:

[0039] When in use, place the base 1 stably in the designated position, ensure that the anti-slip strip 9 at the bottom of the connecting seat 2 is in close contact with the ground, keep the two sets of connecting seats 2 parallel and facing each other, slide the two first protective plates 3 into the connecting groove 7, and fix the first protective plates 3 to the connecting seat 2 by fixing bolts 8.

[0040] According to the required protection length, take the corresponding number of second protective plates 6, slide the connecting plate 11 into the mounting grooves 10 on the upper and lower sides of the first protective plate 3 and the second protective plate 6, so that the inner end faces of the first protective plate 3 and the second protective plate 6 are in contact, and then fix the adjacent protective plates with bolts 5. If it is necessary to extend the fence, increase the number of second protective plates 6.

[0041] After installation, the fence forms a continuous protective barrier through the first protective plate 3 and multiple sets of second protective plates 6, achieving isolation and warning of the bridge construction area and preventing non-construction personnel and vehicles from accidentally entering.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
