Description
Technical Field
[0001] This utility model relates to the field of building protection facilities, and in particular to a modular fiberglass guardrail that is easy to assemble. Background Technology
[0002] Fiberglass guardrails are safety protection facilities made primarily of fiberglass. They combine the strength of glass fiber with the corrosion resistance of plastic, and have advantages such as being lightweight, high-strength, corrosion-resistant, aging-resistant, easy to install and maintain. Therefore, they are widely used in various occasions requiring safety protection.
[0003] Chinese Patent Publication No. CN 100557175C discloses a combined fiberglass guardrail, comprising at least two guardrail panels. The guardrail panels are integrally formed from fiberglass and include a panel body, a first continuous post, a second continuous post, and a continuous crossbar. Both the first and second continuous posts are equipped with steel pipes for fixing, and the second continuous post has a connecting joint. The guardrail panels are fixedly connected at their connecting joints to form a single, integral guardrail.
[0004] The existing technical solutions described above have the following shortcomings: the railings are integrally molded from fiberglass, and if any part is damaged, the entire railing may need to be replaced, which could lead to high maintenance costs. Furthermore, the design of the integrated horizontal bars and posts may require specific tools or methods for installation, increasing the complexity and time involved. Both the first and second integrated posts contain steel pipes for fixing, which requires additional tools and steps during installation, further complicating the process. The connection method may not be flexible enough to adapt to different installation scenarios, leaving room for optimization. Therefore, a modular fiberglass guardrail that is easy to assemble is needed to address the aforementioned problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-assemble modular fiberglass guardrail is simple and quick to operate, greatly improving construction efficiency;
[0015] When assembling the guardrail, the posts are first connected to the base via threaded posts and grooves. The threaded posts are then screwed into the grooves, achieving a quick and secure connection between the posts and the base. Simultaneously, the crossbeams have connecting structures at both ends that mate with the posts, enabling rapid assembly via mortise and tenon joints. These joints include a first fixing hook and a first horizontal plate that latches onto the first fixing hook. When connecting the crossbeams to the posts, the second fixing groove and second fixing hook on the crossbeam mate with the first fixing groove and first fixing hook on the posts, achieving rapid assembly. The crossbeams also have multiple vertical mounting slots, with connecting clips corresponding to connecting chucks, clip shafts corresponding to connecting jaws, and positioning teeth corresponding to positioning slots. When connecting the railing to the crossbeams, the connecting clip at the bottom of the railing mates with the connecting chuck on the crossbeams, achieving rapid fixation of the railing. The operation is simple and convenient, allowing for quick assembly of components without external tools. The simple structure saves costs and facilitates mass production. Furthermore, individual components can be replaced after damage, enhancing the practicality and flexibility of the guardrails. Attached Figure Description
