[0001] The utility model relates to the technical field of building safety construction, in particular to a safety protection structure for an edge opening at a building construction site. Background Art

[0002] Safety protection equipment must be installed at edge openings during construction to avoid safety accidents. Edge opening protection generally uses expansion bolts to anchor the half-moon clamps to the walls on both sides of the edge opening, and then the two ends of the protective steel pipe are respectively fastened to the half-moon clamps on both sides of the edge opening for edge protection. During the installation of the edge opening safety protection device, the use of expansion bolts will cause damage to the wall, and when dismantling it, the expansion bolts need to be installed before the bolts can be removed, which will cause secondary damage to the appearance of the wall in the process.

[0003] Therefore, it is necessary to provide a new safety protection structure for edge openings on construction sites to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a safety protection structure for edge openings at a construction site.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0026] Please refer to Figures 1 to 4 , a safety protection structure for the edge and hole of a building construction site provided by an embodiment of the present utility model, the safety protection structure for the edge and hole of the building construction site includes: a sphere 1, a base 2 and an erection assembly 4.

[0027] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , a retaining rod 5 is fixedly installed at the top of the sphere 1, a base 2 for supporting the sphere 1 is installed at the bottom of the sphere 1, and the sphere 1 is connected to the base 2 through a threaded rod 31. Specifically, a threaded hole B2a is provided on the base 2, a cutting plane 11 is provided at the bottom of the sphere 1, and a threaded hole A1a is provided at the center of the cutting plane 11. A connecting plate 3 is fixedly sleeved in the middle of the threaded rod 31. One side of the connecting plate 3 of the threaded rod 31 is threadedly connected to the threaded hole A1a, and the other side of the connecting plate 3 of the threaded rod 31 is threadedly connected to the threaded hole B2a.

[0028] It should be noted that: the sphere 1 and the base 2 adopt a split structure and are threadedly connected by the threaded rod 31, thereby reducing the difficulty of manufacturing and handling the round stone pier. At the same time, for the problem of damage to the base 2 of the common round stone pier, in this application, the base 2 can be quickly removed and replaced with a new base 2, avoiding the problem that many integral round stone piers need to be replaced due to damage to the bottom; and the sphere 1 and the base 2 are combined to form a structure for blocking the edge and hole of the building construction site. The retaining rod 5 at the top can effectively increase the blocking range of the sphere 1 and will not damage the two side walls of the edge and hole at the same time;

[0029] In this embodiment: the base 2 can be made of wood material to reduce its installation difficulty, and the thread directions of the threaded rods 31 on both sides of the connecting plate 3 can be set in opposite directions.

[0030] In an embodiment of the present utility model, please refer to Figure 2 and Figure 4 , a mounting component 4 for mounting the sphere 1 is installed on the base 2, and the mounting component 4 includes a rotating disk 41. A connecting ring 42 is fixedly fitted on the rotating disk 41, and a plurality of arc-shaped plates 43 which are annularly distributed and rotatably connected are installed on the connecting ring 42. Specifically, a plurality of grooves are formed on the side of the connecting ring 42, and a rotating shaft is installed in each groove. One end of the arc-shaped plate 43 is sleeved on the rotating shaft and rotatably connected to the rotating shaft. A rotating roller 44 which is rotatably connected is installed at the end of each arc-shaped plate 43, and the lower plate wall of each arc-shaped plate 43 is elastically connected to the corresponding position of the rotating disk 41 through a spring 45;

[0031] The rotating disk 41 is rotatably installed on the base 2, and the through cavity opened in the connecting ring 42 is coaxially arranged with the threaded hole B2a opened in the base 2. A plurality of arc-shaped chutes 1b which are annularly distributed and arranged along the outer arc wall of the sphere 1 are formed at the intersection of the section plane 11 and the sphere 1. The arc-shaped plate 43 and the arc-shaped chute 1b are mutually matched, and the rotating roller 44 at the end of the arc-shaped plate 43 is rollingly arranged in the arc-shaped chute 1b.

[0032] It should be noted that: each arc-shaped plate 43 on the connecting ring 42 can be abutted into the arc-shaped chute 1b opened on the outer arc wall of the sphere 1, and a plurality of arc-shaped plates 43 can protect the bottom of the whole sphere 1 in a "claw-shaped structure". When the arc-shaped plate 43 slides along the arc-shaped chute 1b, the arc-shaped plate 43 expands outwards and presses down the spring 45. On the one hand, the thread of the threaded rod 31 is protected, and on the other hand, the connection between the sphere 1 and the base 2 can be facilitated;

[0033] And in this embodiment: the connection method of the spherical stone pier is as follows:

[0034] Step 1: Thread the threaded rod 31 on one side of the connecting disk 3 with the threaded hole A1a until the connecting disk 3 is pressed onto the section plane 11 of the sphere 1;

[0035] Step 2: Align the threaded hole B2a opened in the base 2 with the threaded rod 31 on the other side of the connecting disk 3, and keep each arc-shaped plate 43 corresponding to the arc-shaped chute 1b one by one;

[0036] Step 3: Press the base 2 inward and rotate the base 2 so that the threaded hole B2a in the base 2 is threadedly connected to the threaded rod 31 on the other side of the connecting disk 3. At the same time, the arc-shaped plate 43 expands and slides outwards along the arc-shaped chute 1b until the connecting disk 3 is pressed onto the base 2.

[0037] In step three, since the rotating disk 41 is rotatably installed on the base 2, when the base 2 rotates, the rotating disk 41 can remain relatively stationary under the engagement of the arc-shaped plate 43 and the arc-shaped sliding groove 1b during the rotation of the base 2.

[0038] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
