Technical Field

[0001] The utility model belongs to the technical field of construction safety facilities, in particular to a bridge construction safety protection structure. Background Art

[0002] Roads and bridges are indispensable in people's lives and bring convenience to people. When constructing roads and bridges, protective equipment is needed to protect the construction site.

[0003] At present, the existing specific way to protect the construction site is: the workers place guardrails one by one on the construction site to enclose the construction site for protection. Most guardrails are placed directly on the ground, and a few guardrails are fixed to the ground by anchors to protect the construction site.

[0004] In the current existing technology, when protecting the construction site, since the guardrails are placed one by one by the workers at the construction site, most of the guardrails are placed directly on the ground and there is no connection between the guardrails, resulting in poor stability of the guardrails. When subjected to external forces, the guardrails will be dispersed, causing the protection site to be destroyed, thereby affecting the protection effect. In addition, when the existing guardrail structure is impacted by the human body, the impact on the human body is strong, and it is easy to cause injuries to people. The setting of the guardrail has the opposite effect. Therefore, in view of the above problems, it is urgent to propose a safety protection device. Utility Model Content

To this end, the utility model proposes a bridge construction safety protection structure, which solves the problem that the guardrail in the prior art has poor stability and has a strong impact on the human body when hit.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a bridge construction safety protection structure is provided, comprising a support assembly and a protection assembly, wherein the protection assembly comprises a frame and a protection net, wherein the frame is open on one side, and the protection net is covered and installed at the opening of the frame;

[0007] The support assembly includes a support rod, an insertion rod and a fixing member, wherein the fixing member is used to be installed on the construction bridge deck, one end of the support rod is connected to the fixing member, and the other end of the support rod is connected to the insertion rod;

[0008] A slot corresponding to the insertion rod is provided on one side of the frame away from the protective net, and one end of the insertion rod away from the support rod is plugged into the slot. Connecting components are installed at the edges of both ends of the frame, and the connecting components are used to connect adjacent frames together.

[0009] As a further technical solution of the utility model, the connection assembly includes a collar and a docking rod, the collar and the docking rod are respectively installed at the edges of both ends of the frame, and the docking rod is an inverted L-shaped structure.

[0010] As a further technical solution of the utility model, the inner diameter of the collar is equal to the cross-sectional diameter of the docking rod.

[0011] As a further technical solution of the utility model, a accommodating cavity is provided in the frame body, and the accommodating cavity is filled with an elastic buffer layer, one side of the elastic buffer layer is in contact with the protective net, and the other side of the elastic buffer layer is in contact with the bottom of the accommodating cavity.

[0012] As a further technical solution of the utility model, an elastic connection layer is provided at the connection between the insertion rod and the slot, and the elastic connection layer is fixedly sleeved on the insertion rod.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. In the present invention, the protective net of the protective assembly can more gently buffer the impact from the external environment, avoiding the occurrence of a large reaction force on the impacted object or human body, resulting in damage to the object or injury to the human body.

[0016] 2. In the utility model, the support rod is conveniently fixed on the construction bridge deck by the fixing parts, so that the protection component can be placed on the construction bridge deck more stably, avoiding the unfavorable situation that the protection component is displaced after being hit, resulting in the protection component being unable to provide good protection for personnel or vehicles. By using the connecting parts, on-site construction personnel can more conveniently connect multiple protection components together, so that multiple protection components can work together to form a protection system to better resist impacts from the external environment.

[0017] 3. In the utility model, the insertion rod in the support assembly can cooperate with the card slot of the protection assembly, so that the protection assembly and the support assembly are tightly connected.
