DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 3 As shown, a parapet wall node structure for preventing leakage of an exterior wall comprises a first insulation board 1 and a second insulation board 2 fixedly mounted on a wall body on one side of the parapet wall by means of pins 3, the first insulation board 1 being arranged at a corner of the parapet wall, a plurality of second insulation boards 2 being arranged at an end of the first insulation board 1 away from the corner of the parapet wall, and the second insulation board 2 and the first insulation board 1, as well as two adjacent second insulation boards 2, are connected by means of a quick splicing mechanism, a waterproof layer 4 is arranged on the surfaces of the first insulation board 1 and the second insulation board 2, and the waterproof layer 4 is located at one end of the corner of the parapet wall, close to the parapet wall and extending to the wall body on the other side.

[0025] By arranging the first insulation board 1, the second insulation board 2 and the waterproof layer 4 on the wall of the parapet, the first insulation board 1 and the second insulation board 2 can effectively prevent thermal expansion and contraction, and at the same time, the waterproof layer 4 can effectively prevent water accumulation in the wall and wall erosion.

[0026] The first insulation board 1 and the second insulation board 2 are provided with pin holes 5, and the pins 3 are connected to the wall after passing through the pin holes 5. The first insulation board 1 and the second insulation board 2 can be firmly fixed to the parapet by the cooperation between the pins 3 and the pin holes 5.

[0027] The quick splicing mechanism includes a groove 6 arranged at one end of the first insulation board 1 and the second insulation board 2 opposite to the parapet corner, a hanging plate 7 rotatably installed in the groove 6, and an "L"-shaped hanging rod 8 rotatably installed at one end of the first insulation board 1 and the second insulation board 2 facing the parapet corner. The hanging rod 8 is hung on the front side of the hanging plate 7 through the front end to lock the first insulation board 1 and the second insulation board 2 and the two adjacent second insulation boards 2.

[0028] When performing the splicing operation between the first insulation board 1 and the second insulation board 2, and between two second insulation boards 2, the second insulation board 2 is directly pushed forward so that the front end of the hanging rod 8 is inserted into the groove 6 and finally hung on the front side of the hanging board 7, and the splicing operation is achieved using the hanging rod 8 and the hanging board 7.

[0029] Specifically, the two ends of the hanging plate 7 are respectively in contact with the inner walls on both sides of the groove 6, the hanging plate 7 is rotatably installed in the groove 6 through the first rotating shaft 9, and the hanging rod 8 is rotatably installed at the front end of the second insulation plate 2 through the second rotating shaft 10, and the first rotating shaft 9 is located on the left side of the second rotating shaft 10 in the width direction. The hanging plate 7 rotates forward through the right end so that a channel for the displacement of the hanging rod 8 is formed between its two ends and the side walls of the groove 6.

[0030] During the process of inserting the hanging rod 8 into the groove 6, the front end face of the hanging rod 8 contacts the rear side face of the hanging plate 7. Since the right end of the hanging plate 7 is tilted forward, the hanging rod 8 moves to the right along the rear side face of the hanging plate 7. At the same time, the hanging rod 8 pushes the right end of the hanging plate 7 to rotate forward. After that, the hanging rod 8 enters the front side of the hanging plate 7 along the channel between the right end of the hanging plate 7 and the right inner wall of the groove 6. Then, the second insulation plate 2 is pulled backward so that the hanging rod 8 can be hung on the front side face of the hanging plate 7.

[0031] A clamping block 11 is provided on the front side of the hanging plate 7, and a "V"-shaped clamping groove is formed between the clamping block 11 and the front side of the hanging plate 7. When the front end of the hanging rod 8 is located in the clamping groove, it is parallel to the splicing direction of the first insulation board 1 and the second insulation board 2. When the hanging rod 8 moves to the front side of the hanging plate 7 and then moves backward, the hanging rod 8 enters between the clamping block 11 and the hanging plate 7. The hanging plate 7 is subjected to the pressure of the hanging rod 8 and its own eccentricity, and its two ends are stably supported on the side wall of the groove 6, so that the hanging rod 8 is suspended, and then the second insulation board 2 is fixed by the pin 3, so that the first insulation board 1 and the second insulation board 2, and the two second insulation boards 2 are connected through the quick splicing mechanism.

[0032] The front inner wall surface of the groove 6 is provided with a left side slope 12 and a right side slope 13 whose left end is inclined forward. The right side end of the right side slope 13 is connected to the front end of the right side inner wall surface of the groove 6, the right side end of the left side slope 12 is located behind the left side end of the right side slope 13, and the right side end of the left side slope 12 is located on the right side of the block 11.

[0033] When the hanging rod 8 passes over the hanging plate 7 from the right side to the front of the hanging plate 7, the hanging rod 8 moves on the right inclined surface 13 so that its front end swings to the left. After the hanging rod 8 moves backward, the hanging rod 8 can enter between the block 11 and the hanging plate 7 more smoothly. When removing the connected first insulation board 1 and the second insulation board 2, and removing the two connected second insulation boards 2, first remove the pin 3, then directly push the second insulation board 2 forward, and the hanging rod 8 moves forward and then moves on the left inclined surface 12. The left inclined surface 12 allows the hanging rod 8 to move to the left inner wall surface of the groove 6. At this time, the hanging rod 8 is located on the left side of the rotating shaft in the width direction. In the subsequent process of pulling the second insulation board 2 backward, the hanging rod 8 directly squeezes the left end of the hanging plate 7 backward, so that when the hanging plate 7 rotates, a channel for the hanging rod 8 to leave the groove 6 is formed between the left end of the hanging plate 7 and the left inner wall of the groove 6, so that quick disassembly can be achieved.

[0034] The first insulation board 1 and the second insulation board 2 are sleeved, and two adjacent second insulation boards 2 are sleeved. Specifically, the rear ends of the first insulation board 1 and the second insulation board 2 are both provided with a first through groove, and the front end of the second insulation board 2 is provided with a second sleeve groove 21 for sleeved on the outside of the first sleeve groove 20, and during the splicing process, the second sleeve groove 21 is always sleeved outside the first sleeve groove 20. By utilizing the clearance fit between the first sleeve groove 20 and the second sleeve groove 21, thermal expansion and contraction can be more effectively prevented.

[0035] A trapezoidal baffle 14 is fixedly arranged in the groove 6. The baffle 14 is located between the first rotating shaft 9 and the right end of the hanging plate 7 in the length direction of the hanging plate 7, and a rear pull spring 15 is arranged between the hanging plate 7 and the baffle 14. The rear pull spring 15 applies a backward pulling force to the right end of the hanging plate 7, so that the two ends of the hanging plate 7 are stably supported on the side wall of the groove 6. The angle between the waist edge and the top edge of the baffle 14 is an obtuse angle, so that the waist edge of the baffle 14 facing the notch of the groove 6 is a slope surface. When the hanging rod 8 contacts the waist edge of the baffle 14 facing the notch of the groove 6, it is guided to the right.

[0036] The outside of the waterproof layer 4 is provided with a slope layer 16 inclined toward one side of the parapet corner, and a protective layer 17 is provided outside the slope layer 16. The protective layer 17 is used to more effectively protect the parapet. At the same time, the setting of the slope layer 16 allows the water on the wall to converge in a preset direction for rapid drainage. Specifically, it also includes a drain pipe 18, the inner end of the drain pipe 18 extends to the lower end of the protective layer 17, and the outer end of the drain pipe 18 is located outside the parapet and is connected to a delivery pipe 19. With this setting, the accumulated water will converge to one side of the drain pipe 18 more quickly and be quickly discharged.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
