Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a guardrail device used for foundation pit observation. Background Art

[0002] In building construction, especially in high-rise building construction, the excavation of deep foundation pits is often involved. In order to accurately reflect the actual deformation degree and deformation trend of the building foundation, base and site under the influence of static loads or dynamic loads and environmental factors, it is necessary to start settlement observation from the foundation part at the bottom of the foundation pit. In order to prevent high-altitude fall accidents during the inspection process, the staff with the ruler need to suspend the installation belt for inspection. Since the safety belt hook embedded parts are arranged on the water retaining platform road near the foundation pit, as the inspection position changes, the safety belt needs to be frequently untied and buckled. The operation is cumbersome and brings certain inconveniences to the inspection work. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a guardrail device for foundation pit observation, which can specifically adopt the following technical solutions:

[0004] The utility model provides a guardrail device for foundation pit observation, comprising:

[0005] The brackets are set in pairs on the water retaining platform road near the foundation pit;

[0006] A main body guardrail is arranged between the brackets, the left and right ends of the main body guardrail are respectively connected to the brackets, and a concave window is provided on the top of the main body guardrail;

[0007] A movable guardrail is arranged in the recessed window and is hingedly connected to the main guardrail;

[0008] The locking mechanism is arranged between the movable guardrail and the main guardrail, and is used to lock the movable guardrail and the main guardrail so that they maintain a coplanar state.

[0009] The bracket consists of a counterweight base and a vertical pole extending upward.

[0010] The upright pole is connected to the main guardrail. When the movable guardrail is located in the recessed window, the main guardrail and the movable guardrail form a rectangular structure as a whole.

[0011] The recessed window is a rectangular structure symmetrically arranged along the central axis of the main guardrail. The bottom of the movable guardrail is hingedly connected to the main guardrail, and the top of the movable guardrail is flush with the top of the main guardrail.

[0012] The height of the movable guardrail is 1 / 3-1 / 2 of the height of the main guardrail, and the bottom of the movable guardrail is 1.1-1.3m above the ground.

[0013] The locking mechanism includes a latch lock buckle arranged on the top of the main guardrail and a latch hole correspondingly arranged on the movable guardrail.

[0014] The utility model provides a guardrail device for foundation pit observation, which has an ingenious structure and is easy to use. When the detection window is locked, it can be used as a common guardrail for daily safety protection of the foundation pit. When working, the inspector stands outside the guardrail and flips open the detection window. Then, they insert the measuring ruler through the detection window into the foundation pit to measure the foundation pit data. This operation effectively prevents the occurrence of accidents such as falling from heights by the inspector holding the steel ruler during foundation pit monitoring. The utility model is low-cost, easy to operate, highly feasible, and reusable, effectively ensuring the personal safety of foundation pit inspectors while improving the efficiency of foundation pit inspection.

[0018] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0019] like Figure 1-3 As shown, the guardrail device for foundation pit observation described in the present invention is composed of a bracket 1, a main guardrail 2, and a movable guardrail 3. Two brackets 1 are provided, spaced apart along the water retaining platform road adjacent to the foundation pit. Each bracket 1 is composed of a counterweight base 11 and an upwardly extending vertical pole 12. The main guardrail 2 is mounted between the two vertical poles 12. The main guardrail 2 is a rectangular structure with a recessed window at the top. The movable guardrail 3 is located within the recessed window.

[0020] In this embodiment, the recessed window is a rectangular structure symmetrically arranged along the central axis of the main guardrail 2. The movable guardrail 3 is a rectangular structure that matches the recessed window, with its bottom connected to the main guardrail 2 via a hinge 4 (i.e., hingedly connected to the concave surface of the recessed window). When the movable guardrail 3 is located within the recessed window, that is, when the main guardrail 2 and the movable guardrail 3 are arranged coplanar, their top surfaces are flush, forming an overall rectangular structure.

[0021] To maintain the coplanarity between the main guardrail 2 and the movable guardrail 3, a latch lock 51 is provided at the top of the main guardrail 2, and a corresponding latch hole 52 is provided in the movable guardrail 3, forming a locking mechanism 5. When the latch of the latch lock 51 is inserted into the latch hole 52, the main guardrail 2 and the movable guardrail 3 are locked, coplanar, and form a rectangular protective structure. This structure is used for daily protection outside of inspection work (to prevent pedestrians, objects, etc. from falling into the foundation pit).

[0022] When the latch of latch lock 51 is released from latch hole 52, the movable guardrail 3 can be manually tilted downward to expose the recessed window. At this point, the inspector, standing outside the guardrail, inserts a measuring tape through the recessed window into the foundation pit to perform data measurement. To change the measurement position, simply lock the current main guardrail 2 and movable guardrail 3, then follow the above steps to open the recessed window at the desired measurement location for data measurement.

[0023] In order to ensure the safety of the inspection personnel and facilitate the inspection work, the height of the above-mentioned movable guardrail 3 is usually 1 / 3-1 / 2 of the height of the main guardrail 2, and the bottom of the movable guardrail 3 is 1.1-1.3m above the ground.

[0024] The utility model can effectively ensure the safety of personnel around the foundation pit, and is convenient and quick when measuring the foundation pit, and effectively prevents the occurrence of accidents of personnel holding a steel ruler to monitor falling from a height.

[0025] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
