Description

Technical Field

[0001] The utility model belongs to the technical field of building accessories, and particularly relates to a rotatable parapet protection device and a protection structure containing the device. Background Art

[0002] In construction, edge protection of openings is extremely important and is an important measure to ensure the safety of construction operators, especially the edge protection of roof parapets.

[0003] A roof refers to the surface of a building's roof, while a parapet is a low wall surrounding the roof. When the parapet's height is less than 1.2m, edge protection and safety belt mounting points must be installed during roof edge work. Traditional construction methods, such as those described in Chinese patent applications CN211714555U and CN209211864U, require pre-embedded wall ties during the pouring phase or drilling holes in the wall after it is formed for connection, with subsequent removal or sealing and reinforcement. This complex and time-consuming construction method is not easily reproducible and poses the risk of damaging the wall, compromising the roof's waterproofing and rigidity.

[0004] Chinese patent application CN214462437U discloses an adjustable hanging bracket for a hanging basket that can be mounted on a parapet. The bracket is inserted vertically into the upper end of the parapet through a slot formed by the hanging beam, the front bracket, and the rear bracket. The clamping is achieved by tightening the screw on the rear bracket so that its free end is pressed against the side of the wall. The rear bracket and the screw are only subjected to force at a single point at the threaded connection, resulting in insufficient stability. However, as a hanging bracket for the hanging basket, it is also balanced overall by pre-buried expansion screws, matching wall connectors, and steel wire ropes. If used as an intermediate connector between the guardrail on the parapet and the parapet, its applicability and stability in connection with the wall need to be improved and perfected.

[0024] To avoid single-point stress on the clamping frame 2 connected to the fastening screw 3 through the internal threaded hole and to improve operating temperature resistance, an adjustment plate 5 is provided between the two clamping frames 2, parallel to the clamping surface. Two adjustment screws 51 are vertically fixed to the side of the adjustment plate 5 facing the fastening screw 3. The free ends of the two adjustment screws 51 slide through the corresponding clamping frame 2 and are respectively threadedly connected to the outer side of the clamping frame 2 with adjustment nuts 52. The two adjustment screws 51 are spaced apart vertically, and the fastening screw 3 is located between the two adjustment screws 51.

[0025] When the protective device of the embodiment is used on the wall, please refer to Figure 1 、 Figure 2 A parapet protection structure includes a parapet 6, and a plurality of the above-mentioned turnover parapet protection devices are arranged at intervals at the upper end of the parapet 6 along the extension direction of the parapet 6. Figure 2 Two are shown, with the connecting beam 1 located at the top of the parapet 6, the clamping frame 2 connected with the fastening screw 3 and the adjusting pressure plate 5 located on the outside of the parapet 6, the adjusting pressure plate 5 abuts against the outer side of the parapet 6, and the other clamping frame 2 abuts against the inner side of the parapet 6; the fastening screw 3 is screwed in so that its inner end abuts against the adjusting pressure plate 5, and the adjusting nut 52 abuts against the outer side of the clamping frame 2; the upper end of the sleeve steel pipe 4 is opened and a vertical pole 7 is inserted, and the fastening screw 41 abuts against the vertical pole 7, and each vertical pole 7 is connected together to several horizontal horizontal poles 8 at vertical intervals to form a guardrail, which is detachably connected by fasteners.

[0026] The protective device of the embodiment can be securely attached to the top of the parapet 6 and, by connecting the vertical rods 7 and horizontal crossbars 8, forms a guardrail. It has a simple structure and is easy to use. Both the device and the guardrail are detachable, simplifying the construction process, reducing material consumption, and facilitating turnover and reuse. An adjustable pressure plate 5 is added to the device to improve connectivity with the clamping frame 2 and further ensure operational stability.

[0027] The free end of the adjusting screw 51 is threadedly connected to two adjusting nuts 52 .

[0028] In this way, the adjusting nut 52 closest to the clamping frame 2 can be adjusted to abut against the outer side of the clamping frame 2 first, and then the outer adjusting nut 52 can be screwed in until it abuts against the adjusting nut 52 near the clamping frame 2 to prevent loosening. Similarly, the clamping nut 31 is threadedly connected to the rod section of the fastening screw 3 on the outer side of the clamping frame 2.

[0029] During manufacturing, the connecting crossbeam 1 is constructed from a square steel tube of appropriate wall thickness, with the long side of its cross section positioned horizontally and larger than the outer diameter of the sleeve steel tube 4. The sleeve steel tube 4 is constructed from a construction steel tube one size larger than the uprights 7 to ensure the uprights 7 can fit within the inner bore of the sleeve steel tube 4. The lower end of the sleeve steel tube 4 is vertically welded to the center of the upper surface of the connecting crossbeam 1, with a length of 200mm. Considering the standard thickness of the parapet, the connecting crossbeam 1 is 320mm long. The clamping frames 2 are constructed from 40*40*4mm angle steel, with a length of 300mm. The upper ends of the two clamping frames 2 are vertically welded to the ends of the lower surface of the connecting crossbeam 1, with the outer side of one side of the angle steel forming the clamping surface. The sides of the two angle steels not forming the clamping surface are coplanar. The adjustment plate 5 is constructed from galvanized flat steel, with a length corresponding to the clamping frame 2, 300mm, and a width corresponding to one side of the angle steel.

[0030] Among them, three through holes are vertically spaced apart on one side of the angle steel connected to the fastening screw 3, centered in the width direction. Among them, the upper and lower through holes are 50 mm away from the corresponding ends of the angle steel respectively, and the adjusting screw 51 is welded to the adjustment pressure plate 5 and the distance from the end size corresponds to it, centered in the width direction; the other through hole is located in the middle of the upper and lower through holes. The lengths of the fastening screw 3 and the two adjusting screws 51 are both greater than 100 mm and slide through the through holes one-to-one, and the hole gap is controlled within 1 mm. A fixing nut 21 is welded and fixed to the angle steel.

The internal threaded hole of the fixing nut 21 is threaded with the fastening screw 3, and the fixing nut 21 is welded and fixed to the back of the clamping surface on the angle steel. The outer diameter of each screw is appropriate, and the overall structure satisfies that any part of the device can withstand an external force of 1 kN in any direction.

[0031] To facilitate understanding of the revolving parapet protection device of this embodiment, the use process is further described as follows:

[0032] Adjust the distance between the adjustment plate 5 and the opposite clamping frame 2 to the maximum to facilitate the parapet 6 to be stuck between the adjustment plate 5 and the opposite clamping frame 2; place a number of revolving parapet protection devices at equal intervals at the upper end of the parapet 6 along the extension direction of the parapet 6, with a spacing of ≤2m. The connecting beam 1 is placed on the top of the parapet 6, and the clamping frame 2 connected with the fastening screw 3 and the adjusting pressure plate 5 are located on the outside of the parapet 6. First, screw in the fastening screw 3 so that its inner end abuts against the adjusting pressure plate 5, and push the adjusting pressure plate 5 to abut against the outer side of the parapet 6, and the other clamping frame 2 naturally abuts against the inner side of the parapet 6; then screw in the adjusting nut 52 so that it abuts against the outer side of the outer clamping frame 2, thereby improving the connectivity between the adjusting pressure plate 5 and the clamping frame 2, forming a stable vertical connection that is not easy to overturn; then screw in the adjusting nut 52 on the outside of the adjusting screw 51 until it abuts against the adjusting nut 52 near the clamping frame 2, and screw in the clamping nut 31 on the outside of the fastening screw 3 until it abuts against the fixing nut 21 to prevent loosening. The open upper end of the sleeve steel pipe 4 is inserted into a vertical pole 7 (greater than 1m in length). Fastening screws 41 are used to tighten the vertical pole 7. Each vertical pole 7 is connected to several vertically spaced horizontal crossbars 8 to form a guardrail. The horizontal crossbars 8 are detachably connected to the vertical poles 7 using fasteners (not shown). The vertical spacing between the horizontal crossbars 8 is no greater than 600mm, and both ends extend beyond the vertical poles 7 by at least 100mm. During removal, the guardrail is removed in the reverse order of horizontal crossbars, vertical poles, and then the guardrail.
