DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Embodiment 1:

[0024] like Figure 1-4 As shown, a demolition protection device for the renovation of the exterior facade of a house comprises a mounting rod 1 which can be connected to the required connection position of the exterior facade of the house, brackets 2 are welded and fixed on both sides of the front end of the mounting rod 1, a frame 3 is installed between the brackets 2, a protective net 4 is installed inside the frame 3, a frame-type bearing platform separated from the bracket 2 is provided at the bottom of the bracket 2, a space is reserved between the bearing platform and the bottom of the bracket 2, the bottom of the protective net 4 can be tied to the corresponding position on the bearing platform by a pull rope, and thereby a supporting portion in contact with the bottom of the protective net 4 is formed on the top of the bearing platform, a stretching assembly is connected between the bearing platform and the bracket 2, a sleeve 9 is provided on the side of the bracket 2 away from the protective net 4, a pull shaft 10 which can elastically slide in the vertical direction is provided in the sleeve 9, and the bottom end of the pull shaft 10 is fixedly connected to the bearing platform.

[0025] In this embodiment, the supporting platform includes mutually perpendicular and cross-distributed supporting transverse plates 6 and supporting longitudinal plates 7. The number of supporting transverse plates 6 and supporting longitudinal plates 7 can be adjusted according to the required coverage range of the protective net 4. The supporting transverse plates 6 are connected to the bottom of the supporting longitudinal plates 7, and the supporting transverse plates 6 are fixed together with several supporting longitudinal plates 7 by screws.

[0026] At the same time, the four corners of the bottom of the protective net 4 can be tied to the corresponding positions on the supporting horizontal plate 6 by pulling ropes, and the top of the supporting vertical plate 7 is fitted with the bottom of the protective net 4, so as to unfold the bottom of the protective net 4, and the supporting horizontal plate 6 and the supporting vertical plate 7 under this structure can cooperate with each other to provide good stable support for the bottom of the protective net 4, thereby ensuring that the inside of the protective net 4 can stably and effectively receive falling objects.

[0027] like Figure 3 As shown, the bottom ends of the adjacent pull shafts 10 on the same side are commonly connected to a connecting strip 5, which is used to connect to all or part of the supporting cross plates 6 in the load-bearing platform, and the connection between the supporting cross plates 6 and the connecting strips 5 is fixed with screws.

[0028] like Figure 1As shown, a first boss is provided at the top of the pull shaft 10, and the diameter of the first boss is larger than the diameter of the pull shaft 10, so that a first spring 8 is sleeved between the first boss and the sleeve 9. When the protective net 4 is impacted by falling objects, it will directly act on the supporting horizontal plate 6 and the supporting longitudinal plate 7. When the connecting strip 5 generates a pulling force on the bottom end of the pull shaft 10, the pull shaft 10 moves along its axial direction inside the sleeve 9 and compresses the first spring 8, so that the distance between the bearing platform and the bracket 2 can be lengthened, and the bearing platform will be pulled under the elastic force of the first spring 8, so that the impact force of the falling objects in the protective net 4 can be reduced under the elastic force of the stretching component, so as to achieve a stable support effect for the protective net 4 and the falling objects inside it.

[0029] The sleeve 9 is symmetrically welded and fixed on the side surfaces of the front and rear side regions of the bracket 2 to ensure the connection stability of the supporting transverse plate 6 and the supporting longitudinal plate 7 .

[0030] In this embodiment, the frame 3 and the bracket 2 are connected by bolts.

[0031] Embodiment 2:

[0032] On the basis of the connection between the frame 3 and the bracket 2 in the first embodiment, a reinforcement shaft 11 is added to make the connection between the two more stable, so that after the bracket 2 is fixed to the frame 3 by a plurality of bolts, the reinforcement shaft 11, the reinforcement sleeve 12 and the reinforcement member 13 are connected with each other to play a good reinforcement role and prevent the bolts at the connection between the bracket 2 and the frame 3 from loosening.

[0033] like Figure 1-2 As shown, the four corners of the top of the frame 3 are provided with reinforcement sleeves 12, and a reinforcement shaft 11 is inserted into the reinforcement sleeve 12. A slide groove 201 is opened in the bracket 2. The reinforcement shaft 11 can extend into the reinforcement sleeve 12 by passing through the slide groove on the bracket 2 to reinforce the connection between the frame 3 and the bracket 2.

[0034] like Figure 2 and 4 As shown, an elastically stretchable or shrinkable reinforcement piece 13 is connected between adjacent reinforcement shafts 11 in the same direction, a second boss is provided at the end of the reinforcement shaft 11 away from the frame 3, the diameter of the second boss is larger than the diameter of the reinforcement shaft 11, and the reinforcement piece 13 is connected with a collar 1304 on the shaft section between the second boss of the reinforcement shaft 11 and the bracket 2, the collar 1304 cooperates with the shaft body of the reinforcement shaft 11, so that the reinforcement piece 13 and the reinforcement shaft 11 can be detachably connected.

[0035] In this embodiment, the reinforcing member 13 is provided with a cylinder 1301 connected to the collar 1304, a limited cavity is provided inside the cylinder 1301, and a limited shaft 1302 is connected between the cylinders 1301 on adjacent sides, and a limit block is provided on the limit shaft 1302 to slide with the limit cavity. The limit blocks at both ends of the limit shaft 1302 can make it slide more stably in the limit cavity of the cylinder 1301, and prevent the cylinder 1301 and the limit shaft 1302 from falling off. At the same time, a second spring 1303 is provided on the outer sleeve of the limit shaft 1302, and the ends of the second spring 1303 are respectively connected to the outer end faces of the cylinders 1301 on both sides, so as to provide a stable connection to the reinforcing shaft 11 of the same group, and ensure the reinforcing effect on the bracket 2 when the reinforcing shaft 11 and the reinforcing sleeve 12 cooperate with each other.

[0036] See also Figure 1-4 The specific contents of the demolition protection device used in the renovation of the building facade are as follows:

[0037] First, the mounting rod 1 is used to fix the mounting rod 1 at a suitable position on the exterior facade of the house to be renovated, and then the frame 3 and the bracket 2 are fixedly connected by bolts so that the protective net 4 is horizontally placed between the brackets 2, and the protective net 4 is in a pulled and unfolded state between the brackets 2. When the protective net 4 is fixedly installed, the shaft section of the reinforcing shaft 11 close to the protective net 4 side is inserted into the reinforcing sleeve 12 to reinforce the connection between the frame 3 and the bracket 2, and before the reinforcing shaft 11 is inserted into the reinforcing sleeve 12, the reinforcing member 13 is pre-placed on the shaft section between the second boss of the same group of reinforcing shafts 11 and the bracket 2. At this time, the cylinders 1301 at both ends of the reinforcing member 13 can be moved and the length adjusted on the two ends of the limiting shaft 1302. Since the cylinder 1301 will synchronously drive the second spring 1303 to stretch when pulled, the cylinder 1301 can make the ring 1304 stably sleeved on the reinforcing shaft 11 under the elastic force of the second spring 1303, so as to stabilize the reinforcing shaft 11 installed in the same group.

[0038] When the protective net 4 is impacted by falling objects during the protection process, it will directly act on the supporting transverse plate 6 and the supporting longitudinal plate 7. After the supporting transverse plate 6 and the supporting longitudinal plate 7 are subjected to force, they will generate tension on the bottom end of the pull shaft 10 of the tensile component at the bottom end of the bracket 2 through the connecting strip 5. When the pull shaft 10 is subjected to force, it will move vertically inside the sleeve 9 and compress the first spring 8. In this way, the pull shaft 10 and the connecting strip 5 can provide elastic tension to the supporting transverse plate 6 and the supporting longitudinal plate 7 under the action of the first spring 8, and the supporting transverse plate 6 and the supporting longitudinal plate 7 can elastically support the protective net 4 to reduce the impact force of falling objects on the protective net 4, thereby completing a series of tasks.

[0039] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
