Of course, the device can also be used in the reinforcing scenes of other walls with collapse risks, such as courtyard enclosing walls with loose foundations, various dangerous walls with damaged earthquakes and the like, and when the walls are reinforced, the device can be used for a long time after being installed without being detached.
The reinforcing method for reinforcing the wall by adopting the wall reinforcing auxiliary device for building construction provided by the invention comprises the following steps: :
step 100: fixing the base plate 1 on the ground bearing a wall body to be reinforced through bolts, and keeping the distance between the base plate 1 and the wall surface within the range of 25-60 cm;
step 200: mounting the reinforcing plate 6 on the fixing plate 3, inserting the reinforcing plate 6 on the fixing plate 3 through the embedded groove 9a, and fixing the reinforcing plate 6 and the fixing plate with screws;
step 300: attaching the reinforcing plate 6 to a wall surface to be reinforced, keeping all the pressing plates 93 pressed on the wall surface, adjusting the telescopic mechanism, such as unscrewing the sliding rod 23 in the sliding sleeve 22 of the threaded fixing rod 25, so that the whole surface of the reinforcing plate 6 can be smoothly attached to the wall surface, then continuously adjusting the telescopic mechanism, pressing the supporting component (2) on the reinforcing plate (6) to reinforce the wall body, such as screwing the threaded fixing rod 25, so that the reinforcing plate 6 cooperates with the supporting component 2 and the substrate 1 to form a triangular supporting frame;
step 400: when the pressing force of the reinforcing plate 6 on the wall surface is adjusted, the rotating button 53 is rotated to drive the screw rod 51 to rotate, so that the threaded connecting block 52 slides downwards along the screw rod 51 for a certain distance, the pressing force of the reinforcing plate 6 on the wall surface is enhanced, the upper sliding rod 91c slides for a certain distance in the direction of the reinforcing plate 6 along the through hole formed in the erection plate 9b, and the pressure spring 92c stretches for a certain distance;
step 500: and after the wall body is dried and stable, unscrewing and taking down the bolt for connecting the substrate 1 and the ground, and taking the substrate 1 and the fixing plate 3 away.
When the top of the wall body inclines outwards due to an accident or accident, the wall body pushes the pressing plate 93, so that the pressing plate 93 drives the seesaw 92 to rotate, the pressing plate 94 presses the sodium azide in the telescopic sleeve 8, the sodium azide is pushed to impact and instantly generates a large amount of nitrogen to fill the air cushion 7 on the reinforcing plate 6, and the expanded air cushion 7 can effectively reduce the vibration and scattering phenomena generated after the wall body is strongly impacted or collapsed due to the accident.
The wall body reinforcing auxiliary device for building construction provided by the invention has the following principle:
fixing a base plate 1 on the ground of a wall surface to be fixed through bolts, keeping the distance between the base plate 1 and the wall surface at 25-60cm, inserting a reinforcing plate 6 on a fixing plate 3 through an embedded groove 9a, fixing the reinforcing plate 6 with screws, attaching the reinforcing plate 6 to the wall surface to be reinforced, keeping two pressing plates 93 pressed on the wall surface, loosening a sliding rod 23 in a sliding sleeve 22 of a thread fixing rod 25, enabling the whole plate surface of the reinforcing plate 6 to be smoothly attached to the wall surface, screwing the thread fixing rod 25 after finishing to enable the reinforcing plate 6 to form a triangular supporting frame by matching with a supporting component 2 and the base plate 1, rotating a rotating knob 53 to drive a screw rod 51 to rotate when adjusting the pressing force of the reinforcing plate 6 to the wall surface, enabling a thread connecting block 52 to slide downwards along the screw rod 51 for a certain distance, thereby enhancing the pressing force of the reinforcing plate 6 to the wall surface and enabling an upper sliding rod 91c to slide outwards along a through hole opened by an erection plate 9b, and the pressure spring 92c is stretched for a section, the supporting component 2 plays a supporting role for the reinforcing plate 6 when the wall surface inclines outwards, and the rotating button 53 can be rotated according to the toppling force of a specific wall surface, so that the supporting angle of the supporting component 2 can be flexibly adjusted to reinforce and support the wall body, when the top of the wall body is inclined outwards due to an accident, the wall body pushes the pressing plate 93, so that the pressing plate 93 drives the seesaw 92 to rotate, therefore, the pressing plate 94 presses the sodium azide in the telescopic tube 8, and the sodium azide which is severely impacted is rapidly decomposed to generate a large amount of nitrogen, the chemical equation is NaN 3-NaH + N2, a large amount of nitrogen is instantly generated to fill the air cushion 7 on the reinforcing plate 6, the expanded air cushion 7 can effectively reduce the impact force of the wall body after strong impact, meanwhile, the air cushion 7 expanded after the wall body collapses accidentally can cover part of the wall surface and scattered crushed materials, and the damage of the collapsed wall body to the ground is reduced.
