Description
Technical Field
[0001] This utility model belongs to the field of building hole protection technology, specifically, it relates to a protective device for pre-reserved holes in building construction. Background Technology
[0002] In the field of building construction, whether it is pile foundation engineering or building construction engineering, pre-reserved holes or site holes after the completion of procedures are extremely common.
[0003] Currently, when protecting circular holes, a pair of semi-circular protective frames are typically laid above the hole and then joined together to completely cover it. However, the varying sizes of pre-drilled holes necessitate the preparation of protective frames of different sizes, leading to complex inventory management and high storage costs. Furthermore, as the purpose and size of the holes change at different stages of construction, the existing covers become unsuitable and must be custom-made, resulting in significant material waste and low construction efficiency.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] To address the current problem of protecting circular holes, the common practice is to lay a pair of semi-circular protective frames above the hole and then join them together to completely cover it. However, the varying sizes of pre-drilled holes necessitate the preparation of protective frames of different sizes, leading to complex inventory management and high storage costs. Furthermore, as the purpose and size of the holes change at different stages of construction, the existing covers become unsuitable and must be custom-made, resulting in significant material waste and low construction efficiency. The basic concept of the technical solution adopted in this utility model is as follows: A protective device for reserved holes in building construction includes a first protective frame and a second protective frame, wherein an adjustment and adaptation mechanism and a warning mechanism are installed on the first protective frame and the second protective frame. The adjustment and adaptation mechanism includes a winding frame connected to the outer wall of one side of the second protective frame. The winding frame has a winding shaft inside, and the outer wall of the winding shaft has a protective net wound up and stored. The protective net can be matched with the first and second protective frames to adapt to reserved holes of different sizes. The warning mechanism includes a warning sign installed at the top of the winding frame, which is used to warn construction workers in the surrounding area.
[0006] In a preferred embodiment of this utility model, the adjustment and adaptation mechanism includes a rotating groove formed in the inner wall of the winding frame, a coil spring connected to the inner wall of the rotating groove, the inner outer wall of the coil spring away from the rotating groove being connected to the outer wall of one end of the winding shaft, the protective net being connected to the outer wall of one side of the first protective frame at the end away from the winding shaft, and a handle being connected to the outer wall of the winding frame.
[0007] In a preferred embodiment of the present invention, the warning mechanism includes a fixing block connected to the top of the winding frame. The outer wall of the fixing block has a groove, and the inner wall of the groove has a rotating hole. A torsion spring is connected to the inner wall of the rotating hole. A rotating shaft is connected to the end of the torsion spring away from the inner wall of the rotating hole. One end of the warning sign is connected to the outer wall of the rotating shaft.
[0008] In a preferred embodiment of the present invention, the outer walls of the first protective frame and the second protective frame are provided with threaded holes, and a threaded rod is threadedly connected to the inner wall of the threaded hole. A rotating handle is connected to the outer wall of one end of the threaded rod, and a pressing plate is rotatably provided on the outer wall of the end of the threaded rod away from the rotating handle.
[0009] In a preferred embodiment of this utility model, a baffle is rotatably provided on the top surface of the winding frame.
[0010] In a preferred embodiment of this utility model, the extrusion plate is configured as an arc, and there are two extrusion plates, which are respectively disposed on the first protective frame and the second protective frame.
[0011] In a preferred embodiment of this utility model, there are two warning signs, which are symmetrically distributed on the top surface of the winding frame.
[0012] In a preferred embodiment of this utility model, the outer wall of the warning sign is made of reflective material.
[0013] Compared with the prior art, the present invention has the following advantages: This invention utilizes a first and second protective frame in conjunction with a retractable protective net to provide flexible protection for holes of different sizes. During use, the unfolded width of the protective net can be adjusted, and its position is fixed by a compression mechanism, effectively covering holes of varying sizes and significantly enhancing its adaptability. The protective net retracts and expands with a coil spring, making operation simple and quick. It eliminates the need for multiple sizes of protective frames, greatly reducing storage costs and improving construction efficiency and device reusability.
[0014] This invention features a clever combination of a baffle and a warning sign. After the protective cover is installed, simply moving the baffle releases the restriction on the warning sign, allowing it to unfold to a vertical position under the action of a torsion spring, promptly alerting nearby personnel to stay away and effectively improving the safety of the construction area. When not in use, the warning sign can be pressed down and fixed in place by the baffle. The overall structure is compact, significantly reducing space occupation, facilitating storage and handling, and is easy to operate.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0019] like Figures 1 to 4 As shown, a protective device for reserved holes in building construction includes a first protective frame 1 and a second protective frame 2. An adjustment and adaptation mechanism 31 and a warning mechanism 32 are installed on the first protective frame 1 and the second protective frame 2. The adjustment and adaptation mechanism 31 includes a winding frame 311 connected to the outer wall of one side of the second protective frame 2. A winding shaft 313 is provided inside the winding frame 311, and a protective net 314 is wound up and stored on the outer wall of the winding shaft 313. The protective net 314 can be fitted with the first protective frame 1 and the second protective frame 2 to accommodate reserved holes of different sizes. The hole and warning mechanism 32 include a warning sign 324 set at the top of the take-up frame 311. The warning sign 324 is used to warn the surrounding construction personnel. The adjustment and adaptation mechanism 31 includes a rotating groove opened in the inner wall of the take-up frame 311. A coil spring 312 is connected to the inner wall of the rotating groove. The inner outer wall of the coil spring 312 away from the rotating groove is connected to the outer wall of one end of the take-up shaft 313. The protective net 314 is connected to the outer wall of one side of the first protective frame 1 at the end away from the take-up shaft 313. A handle 315 is connected to the outer wall of the take-up frame 311.
[0020] Furthermore, threaded holes are provided on the outer walls of the first protective frame 1 and the second protective frame 2. A threaded rod 316 is threadedly connected to the inner wall of the threaded hole. A rotating handle 317 is connected to the outer wall of one end of the threaded rod 316. An extrusion plate 318 is rotatably provided on the outer wall of the end of the threaded rod 316 away from the rotating handle 317.
[0021] Furthermore, the extrusion plate 318 is set with an arc shape, and there are two extrusion plates 318. The extrusion plates 318 are respectively set on the first protective frame 1 and the second protective frame 2, so as to fit the hole wall as much as possible, thereby achieving close compression and limiting, and improving the limiting stability.
[0022] The warning mechanism 32 includes a fixing block 321 connected to the top of the take-up frame 311. The outer wall of the fixing block 321 has a groove, and the inner wall of the groove has a rotating hole. A torsion spring 322 is connected to the inner wall of the rotating hole. A rotating shaft 323 is connected to the end of the torsion spring 322 away from the inner wall of the rotating hole. One end of the warning sign 324 is connected to the outer wall of the rotating shaft 323. A baffle 325 is rotatably provided on the top surface of the take-up frame 311.
[0023] Furthermore, there are two warning signs 324, which are symmetrically distributed on the top surface of the winding frame 311, so that they can provide warnings on both the left and right sides, thereby increasing the warning range.
[0024] Furthermore, the outer wall of warning sign 324 is made of reflective material, so that it can reflect light in the nighttime environment as long as there is light shining on it, thus promptly reminding construction workers.
[0025] The implementation principle of the pre-reserved hole protection device in this embodiment is as follows: The first protective frame 1 and the second protective frame 2 can be covered on the pre-reserved hole to protect it. When the hole area is large, the first protective frame 1 is first covered on the hole. Then, the rotating handle 317 is rotated to drive the threaded rod 316 to rotate. As the threaded rod 316 rotates, the extrusion plate 318 moves into the frame and then abuts against the hole wall extending from the hole, thereby covering and limiting the first protective frame 1. Then, the handle 315 is pulled to drive the winding frame 311 to move away from the first protective frame 1. As the winding frame 311 moves, the second protective frame 2 moves synchronously. Since the first protective frame 1 is limited to the hole wall at this time, the protective net 314 wound on the winding shaft 313 will be extended when the winding frame 311 is pulled, thus protecting the gap between the first protective frame 1 and the second protective frame 2. During the extension of the protective netting 314, the winding shaft 313 will rotate. As the winding shaft 313 rotates, the coil spring 312 will rotate, which can adapt to some holes of different sizes, thereby improving the applicability of the device. This eliminates the need to prepare multiple protective frames of different sizes, thereby reducing storage costs and improving construction efficiency. Once the protection is no longer needed, the rotating handle 317 can be released to move the extrusion plate 318 away from the outer wall of the hole, releasing the limit of the first protective frame 1 and the second protective frame 2. Then, the first protective frame 1 and the second protective frame 2 can be pulled upwards, and then the handle 315 can be gradually released. The return rotation of the coil spring 312 can drive the winding shaft 313 to reset and rotate, thereby winding the protective net 314 into the winding frame 311.
[0026] After the first protective frame 1 and the second protective frame 2 are installed, the baffle 325 can be moved. At this time, the outer walls of both ends of the baffle 325 will move away from the top surface of the left and right warning signs 324. In this way, the warning signs 324 will lose their blocking limit. Then, the rotation of the torsion spring 322 will drive the rotating shaft 323 to rotate. The rotation of the rotating shaft 323 will drive the warning signs 324 to rotate upward until they are relatively perpendicular to the fixing block 321. In this way, the warning signs 324 can be used to warn the surrounding construction personnel that they should stay away from the area and not approach. When not in use, simply rotate the warning signs 324 on both sides downwards to align with the top surface of the retractable frame 311, until the baffle 325 is rotated so that the bottom surface is aligned with the top surface of the warning sign 324. At this point, the warning sign 324 will rotate upwards due to the rebound of the torsion spring 322, causing its top surface to press tightly against the bottom surface of the baffle 325, thus creating a certain frictional limiting resistance. This reduces the overall volume and makes it easier to store and retract.
