Fixator for lifeline around foundation pit

Abstract

A fixing device for lifeline around a foundation pit comprises a lifeline body and is characterized in that the lifeline body is a vertical rod, the top end of the vertical rod is arranged to be a hook, a C-shaped ring limiting clamp is fixedly welded to the lower portion of the vertical rod and used for clamping a lifeline steel cable into a limiting bayonet, and the bottom end of the vertical rod is fixedly arranged in a top beam of the foundation pit. The fixing device for the lifeline around the foundation pit has the advantages that the vertical rod is simple in structure and convenient to manufacture, a safety buckle does not need to be unfastened when an operator passes through the position of the fixing device, and the potential safety hazard that the lifeline falls off from the fixing device is effectively reduced.

Description

Technical Field

[0001] The utility model belongs to the technical field of engineering protection, in particular to a lifeline fixer around a foundation pit. Background Art

[0002] During the construction of foundation pit support projects, a lifeline is usually set above the crown beam to effectively reduce the risk of falling for workers.

[0003] The lifeline is fixed above the crown beam through a fixture, and the operator is connected to the lifeline through a safety buckle. When the operator passes the fixed position, the safety buckle must be unfastened. During the period when the safety buckle is separated from the lifeline, the operator has no protective measures, which greatly increases the risk of falling.

[0004] Therefore, the known lifeline fastener structure has the above-mentioned inconveniences and problems. Utility Model Content

[0005] The purpose of the utility model is to provide a safe and reliable lifeline fixer around the foundation pit.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A lifeline fixer around a foundation pit, comprising a lifeline body, characterized in that:

[0008] The lifeline body is a vertical rod, the top of which is configured as a hook, a C-shaped ring limit card is welded below the vertical rod, the C-shaped ring limit card is used to clamp the lifeline steel cable into the limit card slot, and the bottom end of the vertical rod is fixed in the foundation pit crown beam.

[0009] The foundation pit perimeter lifeline fastener of the utility model can also be further implemented by adopting the following technical measures.

[0010] The aforementioned lifeline fixer around the foundation pit, wherein the vertical rod is perpendicular to the crown beam plane.

[0011] After adopting the above technical solution, the lifeline fixer around the foundation pit of the utility model has the following advantages:

[0012] 1. The vertical rod has a simple structure and is easy to manufacture;

[0013] 2. Operators do not need to remove the safety buckle when passing the fixture position;

[0014] 3. Effectively reduce the potential safety hazard of the lifeline fixing device falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a schematic diagram of the structure of a lifeline fixer according to an embodiment of the utility model;

[0016] Figure 2 The figure is a schematic diagram of the use state of the lifeline fastener according to the embodiment of the utility model. DETAILED DESCRIPTION

[0017] The present invention is further described below in conjunction with the embodiments and the accompanying drawings. Example

[0018] The utility model discloses a lifeline fixer for the periphery of a foundation pit, which comprises a lifeline body.

[0019] Please refer to Figure 1-Figure 2 The lifeline body of the lifeline fixture around the foundation pit of the utility model is a vertical rod 1, the top of the vertical rod is set as a hook 2, and a C-shaped ring limit card 6 is welded below the vertical rod. The C-shaped ring limit card is used to clamp the lifeline steel cable 3 into the limit card slot. The bottom end of the vertical rod is fixed in the foundation pit crown beam 4, and the lower part of the crown beam is a support pile 5. The vertical rod is perpendicular to the crown beam plane.

[0020] The construction process of the lifeline fixture around the foundation pit of the utility model is as follows:

[0021] (1) Select lifeline cables according to construction requirements;

[0022] (2) Reserve holes for the crown beam corresponding to the position of the fixator;

[0023] (3) After inserting the fastener into the reserved hole, inject the anchor glue and clip the lifeline cable into the limit slot to prevent the lifeline cable from detaching from the fastener.

[0024] The above embodiments are only for the purpose of illustrating the present invention, but not for limiting the present invention. A person skilled in the relevant technical field may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also belong to the scope of the present invention and should be defined by the claims.

Claims
