During the installation process, it is necessary to build a construction protection frame on the outside of the main building to facilitate the hoisting and installation of the external wall panels. The existing construction protection frame structure is: a steel frame is hung on the outer beam, and each frame is set at intervals of 1.8m.

[0024] The present invention is further described below through specific implementation modes.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, the green assembled building exterior wall panel construction protection device of the present invention comprises a cantilever frame 1, a walking board 2, a longitudinal protection net 3 and a connecting piece 4. The cantilever frame 1 is fixed to the outside of the building beam, the walking board 2 is fixed above the cantilever frame 1, the longitudinal protection net 3 is located on the outside of the walking board 2, and the upper and lower ends of the longitudinal protection net 3 are connected to the adjacent upper and lower cantilever frames 1, and the adjacent upper and lower cantilever frames 1 are connected by the connecting piece 4. The upper and lower cantilever frames 1 are connected by the connecting piece 4 to reduce the torque borne by the end of the cantilever frame 1, thereby improving the bearing capacity of the cantilever frame 1.

[0027] The connecting member 4 is an inclined rope, and the upper and lower ends of the inclined rope are respectively connected to the adjacent cantilever frame 1. The inclined rope has good tensile resistance and occupies a small space, which can increase the activity space of the operator compared with the rod.

[0028] The upper end of the inclined rope is fixedly connected to the middle of the adjacent upper cantilever frame 1, and the lower end is fixedly connected to the outer end of the adjacent lower cantilever frame 1. The upper end of the inclined rope is connected to the middle and the position inside the middle of the cantilever frame 1, and the lower end is fixed to the end of the cantilever frame 1. Since the inner side of the cantilever frame 1 is provided with a triangular stabilizing structure, it serves as the upper suspension point of the inclined rope and has good stability. The lower fixing point of the inclined rope and the cantilever beam is located at the outer end of the cantilever beam, so that the inclined rope pulls the cantilever beam upward at a certain inclination angle, thereby improving the bearing capacity of the cantilever beam.

[0029] like Figure 2 The cantilever frame 1 includes a longitudinal rod 11, a transverse rod 12, an oblique support rod 13 and a longitudinal support rod 14. The longitudinal rod 11 is fixed to the building beam by bolts. One end of the transverse rod 12 is connected to the longitudinal rod 11. The two ends of the oblique support rod 13 are respectively connected to the bottom of the longitudinal rod 11 and the transverse rod 12. The longitudinal support rod 14 is fixed between the transverse rod 12 and the oblique support rod 13. The inner section of the transverse rod 12 and the longitudinal rod 11 and the oblique support rod 13 form a stable structure. The outer side of the transverse rod 12 extends outward to form a suspension beam. The function of the suspension beam is to lay a protective net on the suspension beam to provide additional safety protection in the event that the longitudinal protective net 3 is broken. The lower end of the inclined rope is connected to the end of the outwardly extending suspension beam, and the upper end is connected to the middle of the cantilever frame 1. A trapezoidal structure is formed between the inclined rope and the upper and lower transverse rods 12, which provides a stable structure while reducing the intrusion of the inclined rope into the space above the walking board 2, providing sufficient operating space for operators.

[0030] The top of the oblique support rod 13 is fixedly connected to the middle of the cross bar 12. The oblique support rod 13 is provided with a lower hanging ear 15 with adjustable position, and the inclined tie rod is provided with a plurality of mounting holes for adjusting the position of the lower hanging ear 15. The lower hanging ear 15 is fixed in the mounting hole of the oblique support rod 13 by bolts, and the end of the cross bar 12 is fixed with an upper hanging ear 16, and the upper and lower ends of the oblique rope are connected to the lower hanging ear 15 and the upper hanging ear 16 respectively. Since the lower hanging ear 15 is adjustable on the oblique support rod 13, its position can be adjusted according to the load requirements. When the load is higher, the upper hanging ear 16 is moved inward to reduce the torque of the load on the cantilever frame 1, thereby improving the bearing capacity of the protective device. Therefore, the upper hanging point of the oblique rope can be adjusted according to the load requirements. The upper and lower hanging points of the oblique rope are connected to the upper and lower hanging ears through a basket screw and a tensioner. The tensioner can adjust the length of the oblique rope to adapt to the position of the upper hanging ear. After adjusting to the appropriate position, the oblique rope is adjusted to a suitable tension by loosening the basket screw.

[0031] The cross-sections of the longitudinal rod 11 and the oblique support rod 13 are T-shaped. The T-shaped cross-section can improve the bending resistance of the rod.

[0032] A longitudinal protection rope is arranged between adjacent cantilever beams, and the upper and lower ends of the longitudinal protection rope are respectively fixedly connected to the cantilever beams, and the longitudinal protection net 3 is fixed on the longitudinal protection rope, and a transverse protection net is fixedly arranged under the walking board 2. Compared with the traditional rod as the framework, the longitudinal protection rope is used as the framework of the longitudinal protection net 3, which can significantly reduce the weight and cost of the protection device; the transverse protection net covers the entire cantilever beam in the transverse direction, and the protection net on the cantilever beam can provide additional safety protection.

[0033] The protective device further comprises a transverse transport guide rail 5, which is arranged below the cantilever frame 1 and close to the side of the building beam. The transverse transport guide rail 5 is connected to the cantilever frame 1 through a reinforcing connector 4, and a hoisting hoist is arranged on the transverse transport guide rail 5. The transverse transport guide rail 5 is used to transport the building exterior wall panels. Since the cantilever frame 1 and the inclined rope occupy very little space, the building exterior wall panels can be conveniently transported in the protective device.

[0034] The installation method of the green prefabricated building exterior wall panel construction protection device includes the following steps:

[0035] Step a, fixing the cantilever frame 1 to the outside of the building beam by bolts;

[0036] Step b, laying a transverse protection net on the cantilever beam;

[0037] Step c, installing the walking board 2 above the horizontal protection net;

[0038] Step d. Install the lower hanging ear 15 on the inclined support rod 13 as required, install the inclined rope between the upper hanging ear 16 and the lower hanging ear 15, and adjust the length or tension by a turnbuckle or a tensioner; the tensioner and the turnbuckle can be used together, the tensioner is used to adjust the length of the wire rope to an appropriate length so that it fits the installation position of the lower hanging ear 15, and the turnbuckle is used to adjust the tension.

[0039] Step e, installing longitudinal protection ropes between the cantilever beams;

[0040] Step f: Install the longitudinal protection net 3 on the longitudinal protection rope, and install the transverse transport rail 5 under the cantilever beam. The construction materials hoisted by the hoisting hoist can be transported along the transverse transport rail 5. Since the inclined rope occupies little space, sufficient transportation and installation space is provided.

[0041] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
