[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment 1

[0025] Referring to the drawings Figure 1 The present embodiment provides an elastic sealing assembly type building waterproof joint component, which comprises a filler block 1, a mounting plate 9, a slot expansion piece and a rubber pad 11. In the present embodiment, the filler block 1 is made of PVC plastic. The upper and lower sides of the filler block 1 are provided with rubber pads 11. In the present embodiment, the rubber pads 11 are fixed to the upper and lower sides of the filler block 1, and can be fixed to the filler block 1 by pasting or screwing.

[0026] The filler block 1 has two strip-shaped grooves 7 formed on one side wall thereof along the length direction thereof. The distance from the upper groove 7 to the upper surface of the filler block 1 and the distance from the lower groove 7 to the lower surface of the filler block 1 are both less than 1 cm, and the distance between the two grooves 7 is not less than 3 cm. That is, the thickness of the filler block 1 between the two strip-shaped grooves 7 is relatively thick, and the thickness of the filler block 1 on the two sides is relatively thin. Since the middle part of the filler block 1 is relatively thick and the two sides are relatively thin, when the interference-fitted component is inserted into the groove 7, the filler block 1 will expand to the two sides and compress the rubber pad 11.

[0027] The mounting plate 9 has two slot expansion pieces provided on the side wall thereof and interference-fitted with the two strip-shaped grooves 7, respectively. Since the slot expansion piece and the strip-shaped groove 7 are tightly fitted, when the slot expansion piece is inserted into the strip-shaped groove 7, the filler block 1 will expand to the two sides and compress the rubber pad 11.

[0028] The notch expansion piece in the embodiment includes a plug-in plate 8 and arc-shaped protrusions 10 arranged on the surface of the plug-in plate 8, and the plug-in plate 8 is fixed on the side wall of the mounting plate 9. The thickness of the notch expansion piece is greater than the height of the groove 7, and the specific matching amount can be designed according to requirements.

[0029] In use, the mounting plate 9 is first placed into the prefabricated wallboard joint, and the notch expansion piece faces outward during placement. Then, the groove 7 on the filling block 1 with the rubber pad 11 is aligned with the notch expansion piece, and is knocked into the prefabricated wallboard joint. During the knocking process of the filling block 1, the notch expansion piece is gradually inserted into the strip-shaped groove 7, so that the filling block 1 is expanded to the two sides, and the rubber pad 11 is compressed, so that the joint assembly is tightly matched with the prefabricated wallboard joint.

[0030] When the temperature is low, the filling block 1 shrinks due to cold, and the compression force on the rubber pad 11 decreases. Therefore, the rubber pad 11 that was originally compressed will rebound and expand, thereby compensating for the shrinkage of the filling block 1 and preventing gaps from occurring between the filling block 1 and the inner wall of the prefabricated wallboard joint due to shrinkage of the filling block 1. This effectively prevents water from entering the prefabricated wallboard joint due to shrinkage of the filling block 1, thereby improving the waterproof effect of the joint assembly.

[0031] Embodiment 2

[0032] Referring to the accompanying Figures 2-3 As shown in the drawings, the elastic sealing assembly type building waterproof joint assembly in the embodiment is further provided with a trapezoidal rain shield 2 based on the embodiment 1. The angle of the upper and lower inclined surfaces of the trapezoidal rain shield 2 is less than 45°, and the angle of the upper and lower inclined surfaces of the trapezoidal rain shield 2 in the embodiment is 30°. The trapezoidal rain shield 2 is fixed on the side wall of the filling block 1 away from the groove 7. The abutting surface of the trapezoidal rain shield 2 and the filling block 1 can completely cover the filling block 1, that is, the size of the abutting surface of the trapezoidal rain shield 2 is greater than that of the filling block 1 and can completely cover the filling block 1. The trapezoidal rain shield 2 is uniformly provided with fixing holes 3, and screws are used to fix the trapezoidal rain shield 2 on the surface of the wall through the fixing holes 3.

[0033] Since the trapezoidal rain shield 2 can completely cover the filling block 1, it can effectively prevent rainwater from flowing to the prefabricated wallboard joint. In addition, the inclined surfaces on both sides of the trapezoidal rain shield 2 can guide rainwater, so that the rainwater can flow away from the surface of the trapezoidal rain shield 2.

[0034] In the embodiment, the trapezoidal rain baffle 2 is provided with a plurality of groups of drainage blocks 4 longitudinally and spaced apart on the side wall away from the filler block 1, and a plurality of first drainage grooves 5 are longitudinally arranged on the drainage blocks 4. The length of the drainage block 4 is equal to the width of the outer side of the trapezoidal rain baffle 2. The angle of the upper and lower inclined surfaces of the drainage block 4 is 30°. The inclined surface at the upper end of the drainage block 4 is arranged to increase the inertia of the downward rainwater. A plurality of second drainage grooves 6 are longitudinally and spaced apart on the side wall of the trapezoidal rain baffle 2 away from the filler block 1. The drainage blocks 4 and the second drainage grooves 6 are alternately arranged. Through the arrangement of the first drainage grooves 5 and the second drainage grooves 6, the rainwater can be quickly drained, which is beneficial to the quick drainage of the rainwater on the surface of the trapezoidal rain baffle 2.

[0035] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
