[0022] The utility model embodiment discloses a roof deformation joint waterproof structure.

[0023] The utility model provides a roof deformation joint waterproof structure as shown in Figures 1-4, comprising a wall 1, a waterproof structure layer 2, a cover plate 7 and a cross-shaped connecting rod 8, the two ends of the wall 1 are fixedly connected with the waterproof structure layer 2, the surfaces of the waterproof structure layers 2 at both ends are fixedly connected with a base 3, the side walls of the base 3 at both ends are provided with rolling grooves 4, and a plurality of slide plates 5 are slidably connected between the rolling grooves 4, the tops of the bases 3 at both ends are fixedly connected with L-shaped positioning plates 6, the side walls of the L-shaped positioning plates 6 at both ends are slidably connected with the cover plates 7 through a buffer mechanism, the tops of the cover plates 7 are fixedly connected with a plurality of cross-shaped connecting rods 8, the other end of each cross-shaped connecting rod 8 passes through the side wall of the slide plate 5, the rod wall of each cross-shaped connecting rod 8 is clamped with a first spring 9, the other end of the first spring 9 is fixedly connected to the slide plate 5, the waterproof structure layer 2 is provided, so that the deformation joint between the wall bodies 1 is waterproof, the L-shaped positioning plate 6 is provided to be positioned with the cover plate 7 through the buffer mechanism to prevent the cover plate 7 from being installed. Move left and right, and use the cross-shaped connecting rod 8 set at the bottom of the cover plate 7 to clamp the first spring 9 through the rod wall, so that when the top of the cover plate 7 is affected by snow or other objects, the force can be evenly dispersed to the slide plate 5 and the base 3 through the cross-shaped connecting rod 8 and the first spring 9. The buffer mechanism is set so that when the wall 1 shakes, the cover plate 7 and the base 3 play a buffering role, and no deformation will occur, thereby solving the problem of deformation and eventual breakage of the connection between the base and the cover plate caused by house shaking and snow accumulation during long-term use.

[0024] In order to play a buffering role at the connection between the base and the cover plate, as shown in Figure 1-3, the buffer mechanism includes a positioning block 10, a second spring 11 and a U-shaped plate 12. The inner side walls at both ends of the cover plate 7 are fixedly connected with a plurality of positioning blocks 10, each positioning block 10 is fixedly connected with a plurality of second springs 11, and the other end of each second spring 11 is fixedly connected with a U-shaped plate 12. One end of the U-shaped plate 12 passes through the positioning block 10, and each positioning block 10 is slidably connected to the L-shaped positioning plate 6. The second spring 11 and the U-shaped plate 12 arranged in the cavity of the positioning block 10 are used to play a buffering role at the connection between the base and the cover plate to prevent deformation.

[0025] In order to waterproof the deformation joint in the wall 1, as shown in Figures 1 and 4, the waterproof structural layer 2 includes a waterproof membrane 13 and a Z-shaped waterproof corner code 14. The walls 1 at both ends are fixedly connected with the waterproof membrane 13, and the two ends of the waterproof membrane 13 are fixedly connected with the Z-shaped waterproof corner code 14. One end of the Z-shaped waterproof corner code 14 at both ends is fixedly connected to the base 3. The waterproof membrane 13 set on the surface of the deformation joint in the wall 1 and the Z-shaped waterproof corner code 14 at both ends are used to waterproof.

[0026] In order to play a buffering role between the walls 1, as shown in Figure 1, a filling layer 15 is fixedly connected between the side walls of the walls 1 at both ends. The filling layer 15 is a polyurethane foam layer. The filling layer 15 of polyurethane foam arranged in the deformation joint between the side walls of the wall 1 plays a certain buffering role.

[0027] In order to follow the movement when the wall 1 swings or is squeezed, as shown in Figures 1 and 2, both ends of the side walls of each slide plate 5 are rotatably connected with balls 16, and the balls 16 at both ends are rollingly connected to the rolling groove 4. By using the balls 16 arranged at both ends of the slide plate 5, when the wall 1 swings or is squeezed, the balls 16 drive the cover plate on the slide plate 5 to follow the movement in the rolling groove 4, thereby playing a certain shock-absorbing role.

[0028] Finally, in order to prevent mutual wear and corrosion of metals during long-term use, as shown in Figures 1-4, the other end of each U-shaped plate 12 is fixedly connected to a rubber plate 17, and the rubber plate 17 arranged at the other end of the U-shaped plate 12 is used to prevent mutual wear and corrosion of metals during long-term use.

[0029] Working principle:

[0030] During installation, a layer of waterproof membrane 13 is first laid on the deformation joint in the wall 1, and Z-shaped waterproof angle codes 14 are fixedly installed at both ends of the waterproof membrane. The base 3 is fixedly installed on the top of the Z-shaped waterproof angle codes 14 at both ends, and the slide plate 5 is installed in the rolling groove 4 at both ends through the rolling groove 4 opened on the base 3. The ball bearings 16 arranged at both ends of the slide plate 5 drive the cover plate on the slide plate 5 to follow the movement in the rolling groove 4 when the wall 1 swings or squeezes, thereby playing a certain shock-absorbing role. An L-shaped positioning plate 6 is fixedly installed at one end of the base 3 at both ends, and the limiting blocks 10 on the inner walls at both ends of the cover plate 7 are plugged from one end of the L-shaped positioning plate 6. The positioning block 10 and the cover plate 7 are positioned by the L-shaped positioning plate 6, so as to facilitate installation by tools such as self-tapping screws. The second spring 11 and the U-shaped plate 12 arranged in the cavity of the positioning block 10 are used to align the base 3 and the cover plate 7. The connection between the two acts as a buffer to prevent deformation. The cross-shaped connecting rod 8 arranged at the bottom of the cover plate 7 is connected with the first spring 9 through the rod wall. When the top of the cover plate 7 is subjected to accumulation of snow or other objects, the force can be evenly dispersed to the slide plate 5 and the base 3 through the cross-shaped connecting rod 8 and the first spring 9, thereby solving the problem of deformation and eventual breakage of the connection between the base and the cover plate caused by house shaking and snow accumulation during long-term use.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
