[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0022] See also Figure 1 , Figure 2 and Figure 3 The dangerous building reinforcement support device of the utility model includes a bottom frame 14 fixed to the ground, a fixed support frame is installed at the front of the bottom frame 14, a lifting support frame is installed on the fixed support frame, the height of the fixed support frame cannot be changed, and the height of the lifting support frame can be adjusted by lifting and lowering. The fixed support frame and the lifting support frame together constitute a front support frame, and the front support frame is integrated with the wall of the dangerous building.

[0023] The fixed support frame includes a left column 4 and a right column 11 opposite to each other, each of which is provided with a support beam slide groove 19, and a plurality of lower link beams 12 are installed between the two. A connecting plate 8 is installed on the outer side of both the left column 4 and the right column 11, and a connecting hole is provided on the connecting plate 8. When fixedly connected to the wall, long bolts drilled through the holes in the wall pass through the connecting holes on the connecting plate 8.

[0024] In this embodiment, the bottom frame 14 includes a rectangular frame body, connecting blocks are provided on both sides of the front part of the frame body and convex ridges are provided on the front part of the connecting blocks, the lower ends of the left column 4 and the right column 11 are welded and fixed to the connecting blocks on this side and the convex ridges are embedded in the lower end of the support beam slide groove 19, and the lower ends of the left column 4 and the right column 11 are flush and higher than the bottom surface of the bottom frame 14.

[0025] By embedding the convex ridge at the front of the connecting block into the lower end of the supporting beam slide groove 19, the structural strength of the connection between the lower end of the column and the bottom frame 14 is improved. By making the lower end of the column higher than the bottom surface of the bottom frame 14, a rectangular notch is formed between the lower part of the fixed support frame and the front part of the bottom frame 14. In this way, when the reinforcement support device is installed and used between the wall and the ground, the notch can prevent the reinforcement support device from directly contacting the corner of the wall, which significantly improves the stability of the reinforcement support device.

[0026] The lifting support frame includes a relative left lifting support beam 5 and a right lifting support beam 7, and a plurality of upper connecting beams 6 are installed therebetween. The lower portion of the left lifting support beam 5 is located in the support beam slide groove 19 of the left column 4, and the lower portion of the right lifting support beam 7 is located in the support beam slide groove 19 of the right column 11. Check assemblies are installed between the left lifting support beam 5 and the left column 4, and between the right lifting support beam 7 and the right column 11.

[0027] The upper connecting beam 6 combines the left lifting support beam 5 and the right lifting support beam 7 into a whole, and the left lifting support beam 5 can be lifted and moved in the left support beam slide 19, and the right lifting support beam 7 can be lifted and moved in the right support beam slide 19, so as to realize the lifting and lowering adjustment of the lifting support frame. By setting a check assembly, after the lifting and lowering adjustment of the lifting support frame is completed, the left lifting support beam 5 and the left column 4, and the right lifting support beam 7 and the right column 11 can be automatically maintained at the current set position.

[0028] A connecting plate 8 is provided on the outer side of the left lifting support beam 5 and the right lifting support beam 7. The connecting plate 8 is provided with a connecting hole. When fixedly connected to the wall, long bolts that penetrate the holes drilled in the wall pass through the connecting holes on the connecting plate 8.

[0029] In this embodiment, guide bars 18 are provided on the inner sides of both the left lifting support beam 5 and the right lifting support beam 7, and guide grooves 20 penetrating the support beam slide groove 19 are provided on the left column 4 and the right column 11, and the guide bars 18 are located in the guide grooves 20 on this side. By providing the guide bars 18 and the guide grooves 20, the stability of the left lifting support beam 5 in the left support beam slide groove 19 and the right lifting support beam 7 in the right support beam slide groove 19 is improved.

[0030] In this embodiment, the non-return assembly between the left lifting support beam 5 and the left column 4 includes a left rack 1 installed on the left lifting support beam 5 and a non-return device 3 installed on the left column 4; the non-return assembly between the right lifting support beam 7 and the right column 11 includes a right rack 9 installed on the right lifting support beam 7 and a non-return device 3 installed on the right column 11. Figure 3 As shown in the figure, the backstop 3 includes a backstop shaft seat respectively located on both sides of the support beam slide groove 19 and a backstop rotating shaft installed between the two backstop shaft seats, and a backstop locking plate is installed on the backstop rotating shaft. When the rack moves upward (called the forward tooth direction), the backstop locking plate is disengaged from between the teeth, so that the lifting support beam and the rack can be moved upward arbitrarily. When the rack moves downward (called the reverse tooth direction), the backstop locking plate is embedded between the teeth, so that the lifting support beam and the rack cannot be moved downward arbitrarily.

[0031] It can be imagined that when the lifting support beam and the rack need to be shifted downward, the non-return lock plate of the non-return device 3 can be manually disengaged from the teeth of the rack, and after adjusting the height to a suitable level, the non-return lock plate can be manually embedded between the teeth of the rack.

[0032] It also includes a telescopic support, which is used to support the front support frame. The upper end of the telescopic support is combined with one of the upper connecting beams 6, and the lower end is fixed to the ground.

[0033] In this embodiment, the telescopic support includes an upper support body 10, a lower support body 15 and a support rod 13 located therebetween. The upper end of the upper support body 10 is combined with the upper connecting beam 6, and a base plate 16 is installed at the lower end of the lower support body 15. An unthrough center hole is provided on the upper support body 10 and / or the lower support body 15, and the end of the support rod 13 is located in the corresponding center hole.

[0034] like Figure 1 As shown in , the upper connecting beam 6 is a round steel, and a semicircular groove is provided at the upper end of the upper support body 10. When the telescopic support is used to support the front guard frame, the middle of one of the upper connecting beams 6 falls into the groove at the upper end of the upper support body 10. Since the end of the support rod 13 falls into the non-through center hole on the upper support body 10 and / or the lower support body 15, the length of the telescopic support can be changed. After the reinforcement support device is installed in place, a welding machine is used to weld the upper support body 10 and the support rod 13, and the lower support body 15 and the support rod 13, so as to lock the telescopic support in the current support state.

[0035] In this embodiment, a corrugated pad 2 is also included, and the corrugated pad 2 is located between the wall and the fixed support frame and the lifting support frame. Figure 1As shown in , the corrugated pad 2 is formed by pressing a steel plate, and the overall structural strength is improved by setting a plurality of parallel right-angled corrugations. The corrugated pad 2 acts as a pad between the wall and the front support frame, and its significance is: under normal circumstances, the wall of the dangerous building has undergone a certain deformation and the surface is not flat. At this time, the front support frame cannot fit well with the wall. The corrugated pad 2 is set between the wall and the front support frame. When the long bolts that pass through the wall and the connecting plate 8 (the long bolts penetrate the corrugated pad 2) are tightened, the corrugated pad 2 itself can undergo a certain deformation, which can significantly improve the bonding effect between the reinforcement support device and the wall.

[0036] In this embodiment, a plurality of anchor holes are provided on the frame body of the bottom frame 14 , and anchor holes are provided on the bottom plate 16 of the telescopic support. The frame body of the bottom frame 14 and the bottom plate 16 are fixedly connected to the ground by ground anchors 17 .

[0037] Construction method:

[0038] At the construction site, the height of the reinforcement support device is adjusted and set according to the specific conditions of the dangerous building; after the height adjustment is completed, the drilling positions are marked on the wall of the dangerous building according to the positions of each connecting plate 8, and then holes are drilled on the wall using a drilling tool; a metal pad is set on the inner side of the wall, and long bolts are used to penetrate the connection holes on the metal pad, the drilled holes on the wall, the corrugated pad 2 and the connection holes on the connecting plate 8 and fasten them; the bottom frame 14 is fixedly connected to the ground using ground anchors 17;

[0039] Then install the telescopic support, combine the upper end of the telescopic support with the middle part of the upper connecting beam 6, let the bottom plate 16 of the lower end of the lower support body 15 fall on the ground and be fixedly connected to the ground with anchor nails 17, use hydraulic jacking tools to support the upper support body 10 and the lower support body 15, so that the telescopic support can generate appropriate jacking force for the front support frame, and then use a welding machine to weld the upper support body 10 and the support rod 13, and the lower support body 15 and the support rod 13.
