Description

Technical Field

[0001] The present invention relates to the field of assembled exterior walls, and in particular to an assembly exterior wall installation method. Background Art

[0002] Prefabricated building walls, also known as exterior wall decorative panels, have the properties of beautification, heat insulation and thermal insulation.

[0003] Exterior wall panels are fixed to the wall using specific threaded anchor nails or expansion nails (hereinafter referred to as fixing nails). Publication (announcement) No. CN102877622A, published on January 16, 2013, discloses a mounting structure for exterior wall panels. Therefore, exterior wall panels offer the advantages of fast installation efficiency and quick subsequent repair and replacement.

[0004] Since these fixing nails are fixed by nut design, the head cap position of the fixing nail will become loose due to external forces such as wind, earthquake and resonance after fixation, so there may be a risk of the exterior wall decorative panels falling off. Summary of the Invention

[0005] The present invention aims to provide a method for installing an assembled exterior wall to prevent the fixing nails from loosening and the exterior wall from falling off.

[0006] To achieve the above object, the present invention adopts the following technical solution: a method for installing an assembled exterior wall, comprising the following steps:

[0007] S01. Drill a hole in the wall in advance, and then insert the expansion sleeve into the hole;

[0008] S02. Prepare a base plate. The base plate has a fixing hole. A floating plate is slidably connected to the fixing hole. A plurality of strip plates arranged in a circular array are also provided in the fixing hole. One end of each strip plate is connected to the inner wall of the fixing hole, and the other end of each strip plate is connected to the floating plate. The strip plates are spirally arranged along the length of the fixing hole to form an inner hole. A fixing nail is inserted through the inner hole for fixing. The fixing nail is then threadedly assembled with the expansion sleeve.

[0009] S03. Press the head cap of the fixing nail onto the floating plate. The floating plate is pushed and moves, and the strip plate is pressed and rotates and contracts in a spiral direction to surround the fixing nail.

[0010] The beneficial effects of this program are:

[0011] 1. During the installation process, the head cap of the fixing nail presses on the floating plate, the floating plate is pushed and moved, and the strip plate is pressed and rotated in the spiral direction to embrace the fixing nail, so that the clamp forms an anti-slip effect on the fixing nail.

[0012] 2. In the prior art, the fixing hole is usually designed to be a conical surface to achieve a clamping effect during the rotation of the fixing nail. However, during the use of the exterior wall, due to the interference of external forces such as wind, earthquake and resonance, the fixing nail will also loosen outward under the action of external forces due to the outward inclination of the conical surface of the fixing nail, thereby losing the clamping effect; while in this solution, the strip plate is set to be spiral. When the head cap of the fixing nail presses on the floating plate, it drives the floating plate to rotate in a direction perpendicular to the axis of the fixing hole. The floating plate drives the strip plate to twist (rotate and shrink), causing the inner hole to shrink, so as to achieve the effect of embracing the fixing nail. During the process, the inner side of the strip plate is always parallel to the axis direction of the fixing hole, and will not push the fixing nail to loosen outward, so as to achieve the effect of preventing the nut position of the fixing nail from loosening and the exterior wall from falling off.

[0013] 3. As multiple strip boards work together to embrace the fixing nails, even if some strip boards are damaged in disasters such as earthquakes, the remaining strip boards can still embrace the fixing nails to prevent the nuts from loosening and the exterior wall from falling off.

[0014] Preferably, as an improvement, the strip plate is provided with a groove that mates with the thread of the fixing pin. This arrangement, through the provision of the groove, allows the fixing pin and the strip plate to be more tightly coupled, thereby enhancing the effect of securing the fixing pin. During rotation, the fixing pin contacts the groove, pushing the strip plate to rotate and retract, preventing the strip plate from getting stuck and unable to rotate and retract.

[0015] Preferably, as an improvement, the floating plate includes a first plate member, a second plate member, and an elastic connector. The first plate member and the second plate member are maintained at a predetermined distance by the elastic connector. The first plate member is provided with a limiter capable of limiting the rotation of the first plate member perpendicular to the length direction of the fixing hole. The strip plate is connected to the second plate member. In this arrangement, if the first plate member is not restricted from rotating, then, after being disturbed by external forces such as wind, earthquake, and resonance, the first plate member and the head cap of the fixing nail will rotate together, accelerating the loosening of the fixing nail. In this solution, however, the rotation of the first plate member is restricted, and the friction between the first plate member and the head cap of the fixing nail is utilized to prevent the fixing nail from loosening after rotation. Moreover, because the first plate member and the second plate member are connected by the elastic connector, the first plate member does not hinder the rotation of the second plate member and the strip plate.

[0016] Preferably, as an improvement, the elastic connector includes a plurality of arched members and push rods, the arched members being arranged in a circular array on the second plate, and the push rods being arranged in a circular array on the first plate. The push rods and arched members abut against each other, and the ends of the push rods are tilted in a clockwise or counterclockwise direction. In this arrangement, when the head caps of the fixing pins are pressed against the first plate, the first plate, via the push rods, pushes the second plate in a clockwise rotation, thereby driving the strip plates to rotate and contract.

[0017] Preferably, as an improvement, the end of the push rod is tilted away from the axis of the fixing hole, and the first plate has a plurality of perforations arranged in a circumferential array, through which the arched member can pass. With this arrangement, when the first plate pushes the second plate to its limit position, the push rod pushes up the arched member, which then passes through the perforations, filling the space between the head cap of the fixing nail and the fixing hole, thereby clamping the head cap of the fixing nail and preventing the head cap from falling off.

[0018] Preferably, as an improvement, one end of the substrate is provided with a tenon, and the other end of the substrate is provided with a tenon groove, and the shapes of the tenon and the tenon groove cooperate with each other. In this way, the tenon and the tenon groove cooperate with each other to achieve connection between adjacent substrates.

[0019] Preferably, as an improvement, slots are provided on both sides of the tenon, and pins are slidably provided on the inner walls of both sides of the tenon slot. The shapes of the pins and the slots match each other, and the pins are provided with a toothed plate, which is meshed with a gear. A pull rope is also included, one end of which is connected to a strip plate, and the other end of the pull rope is connected to the gear. When the strip plate rotates and contracts, the pull rope pulls the gear to rotate, and the gear drives the pins through the toothed plate to insert into the slots. This arrangement has the following effects:

[0020] 1. When the strip plate rotates and contracts, the pull rope pulls the gear to rotate, and the gear drives the pinion to insert into the slot through the tooth plate to achieve the connection between adjacent base plates.

[0021] 2. The loosening of the fixing nails is not easy to detect, but in this solution, once the bolts are loose, the pull rope will inevitably loosen, thereby loosening the connection between the tenon and the mortise, so that maintenance personnel can find the problem in time and replace the base plate in time; if the fixing nails are completely loosened, the base plate will lose stability and flip over and fall, which is difficult to remedy.

The limiting portion 212 can limit the rotation of the first plate 21 perpendicular to the length direction of the fixing hole 11, as shown in FIG. Figure 4 As shown, the right end of the strip plate 3 is welded to the second plate 22 .

[0036] The elastic connecting member includes a plurality of arched members 51 and a push rod 52, such as Figure 2 As shown, the arched members 51 are arranged in a circumferential array on the right side of the second plate 22. The arched members 51 are made of rubber. The push rods 52 are welded in a circumferential array on the left side of the first plate 21. The push rods 52 and the arched members 51 are offset against each other. Figure 5 As shown, the end of the push rod 52 is tilted in the clockwise direction, and the end of the push rod 52 is tilted in the direction away from the axis of the fixing hole 11. The length of the push rod 52 can be adaptively set according to actual conditions to promote the rotation of the second plate 22. A plurality of clockwise elliptical through-holes 211 are arranged in a circular array on the first plate 21, and the arched member 51 can pass through the through-hole 211. The number and position of the arched member 51, the push rod 52 and the through-hole 211 correspond one to one.

[0037] The upper end of the base plate 1 is provided with a tenon 12, and the lower end is provided with a tenon groove 13. The shapes of the tenon 12 and the tenon groove 13 match each other.
