Description

Technical Field

[0001] The utility model belongs to the technical field of wall connection, in particular to an external wall brick-disassembly-free connection piece. Background Art

[0002] Exterior wall non-removal bricks are a new type of building material. This brick is different from traditional exterior wall tiles. This brick does not need to be removed again after installation, so it is called non-removal bricks.

[0003] This type of wall is usually composed of a combination of multiple walls, including a solid coating layer, a finishing layer, a plaster layer, an insulation layer and an exterior wall structure. These walls can be combined through expansion screws to form a demolition-free wall.

[0004] It has been found through long-term use and observation that the existing wall connectors need to embed screws deep into the wall when fixing and connecting the wall, because the wall has many layers, and then uniformly fix and connect the layers of the wall to reduce the possibility of the wall falling off during long-term use.

[0005] To this end, the utility model provides an external wall brick-removal-free connector. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the utility model describes an external wall non-removal brick connector, comprising a threaded nail body; an expansion sheet is provided on the outside of the threaded nail body; the expansion sheet is arranged in multiple stages; a self-tapping head is fixedly connected to the bottom of the threaded nail body; the self-tapping head is arranged in a conical shape; a gasket is arranged in the middle of the threaded nail body; the gasket is arranged in an annular shape and contacts the middle of the threaded nail body. Through the above structure, the solid coating layer, the finishing layer, the plaster layer, the insulation layer and the external wall structure can be fixed and connected, thereby realizing the non-removal process of the external wall. By connecting the wall body through multiple such connectors, the risk of the wall body breaking and falling off during long-term use is reduced.

[0008] Preferably, a plurality of slots are provided in the middle of the expansion sheet; the plurality of slots are equidistantly distributed along the length of the expansion sheet; the ends of the plurality of slots are fixedly connected with lift pieces; the lift pieces and the slots are in the same horizontal plane. Through the above structure, multiple lift pieces can cooperate with the expansion sheet to expand, thereby achieving fixation of multi-layer walls, further enhancing the fixation of the walls, and further reducing the risk of wall falling off.

[0009] Preferably, a rubber pad is fixedly connected to the top of the gasket; the radius of the rubber pad is the same as the radius of the top of the threaded nail body. Through the above structure, the rubber pad with greater friction is in direct contact with the threaded nail body, thereby reducing the difficulty in fitting caused by sliding between the gasket and the threaded nail body due to the smaller friction between the threaded nail body and the gasket when the threaded nail body is rotated.

[0010] Preferably, the side walls of the plurality of lift pieces are fixed with a plurality of serrations; the plurality of serrations are evenly distributed along the length of the lift piece. Through the above structure, the plurality of serrations can be combined with the lift piece to connect the wall, thereby reducing the situation where the lift piece is too smooth on the side and becomes loose inside the wall.

[0011] Preferably, a plurality of leakage holes are provided in the middle of the expansion piece; the plurality of leakage holes are equidistantly distributed along the length of the expansion piece and are staggered with the slot. The above structure can reduce the occurrence of blockage inside the expansion piece caused by excessive accumulation of debris inside the expansion piece.

[0012] Preferably, the bottoms of the plurality of lift pieces are all fixedly connected with fixing hooks; the fixing hooks are arranged facing the outside of the expansion piece, and through the above structure, the connection between the lift piece and the wall is further increased.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. The utility model discloses an external wall non-dismantling brick connector, which can fix and connect the solid coating layer, the finishing layer, the plaster layer, the insulation layer and the external wall structure, thereby realizing a non-dismantling process of the external wall. By connecting the wall with a plurality of such connectors, the risk of the wall breaking and falling off during long-term use is reduced.

[0015] 2. The utility model discloses an external wall brick connector that does not require disassembly, which can achieve fixation of multi-layer walls by allowing multiple sections of warping pieces to cooperate with expansion pieces, thereby further enhancing the fixation of the wall and further reducing the risk of the wall falling off.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 4 As shown, an external wall non-removal brick connector described in an embodiment of the utility model includes a threaded nail body 1; an expansion piece 12 is provided on the outside of the threaded nail body 1; the expansion piece 12 is arranged in multiple stages; a self-tapping head 13 is fixedly connected to the bottom of the threaded nail body 1; the self-tapping head 13 is arranged in a conical shape; a gasket 14 is provided in the middle of the threaded nail body 1; the gasket 14 is arranged in an annular shape and contacts the middle of the threaded nail body 1. When working, the external wall structure, thermal insulation layer, plaster layer, finishing layer and overall reinforcement coating are arranged in sequence. When the arrangement is completed, the threaded nail body 1 can be installed on the surface of the overall reinforcement coating. At this time, as the threaded nail body 1 is placed on the surface of the overall reinforcement coating, the threaded nail body 1 is twisted. As the threaded nail body 1 is twisted, the expansion piece 12 contacts the overall reinforcement coating. At this time, as the threaded nail body 1 is continuously twisted , the expansion sheet 12 will destroy the overall reinforcement coating, finishing layer, plaster layer, insulation layer and exterior wall structure in turn. At this time, as the expansion sheet 12 destroys these wall surfaces, the expansion sheet 12 will also extend to the inside of the wall along with the threaded nail body 1. At this time, the gasket 14 and the overall reinforcement coating are in contact. At this time, as the threaded nail body 1 rotates and the wall restricts the expansion sheet 12, the thread in the middle of the threaded nail body 1 will open the expansion sheet 12 and then form a barb. At this time, the threaded nail body 1 can be fixed to the inside of the wall. At the same time, multiple threaded nail bodies 1 can be used to fix multi-layer walls. Through the above structure, the solid coating, finishing layer, plaster layer, insulation layer and exterior wall structure can be fixed and connected, thereby realizing the demolition-free process of the exterior wall. The wall is connected by multiple connecting parts, which reduces the risk of fracture and shedding of the wall during long-term use.

[0024] like Figures 1 to 3As shown, a plurality of slots 2 are provided in the middle of the expansion piece 12; the plurality of slots 2 are equidistantly distributed along the length of the expansion piece 12; the ends of the plurality of slots 2 are fixedly connected with flaps 21; the flaps 21 and the slots 2 are in the same horizontal plane. During operation, as the threaded nail body 1 is rotated, the threaded nail body 1 and the expansion piece 12 are extended to the inside of the wall. At this time, as the threads in the middle of the threaded nail body 1 continuously contact the inner wall of the expansion piece 12, the flap 21 in the middle of the expansion piece 12 will expand as the expansion piece 12 expands. At this time, the plurality of flaps 21 and the expansion piece 12 can be expanded at the same time, and then the multi-layer wall can be fixed. Through the above structure, the multi-section flaps 21 can cooperate with the expansion piece 12 to expand, thereby realizing the fixation of the multi-layer wall, further enhancing the fixation of the wall, and further reducing the risk of the wall falling off.

[0025] like Figure 1 and Figure 4 As shown, a rubber pad 3 is fixed to the top of the gasket 14; the radius of the rubber pad 3 is the same as the radius of the top of the threaded nail body 1. During operation, as the top of the threaded nail body 1 is rotated, when the threaded nail body 1 and the top of the gasket 14 come into contact, the gasket 14 can cooperate with the threaded nail body 1 and the expansion sheet 12 to fix the threaded nail body 1 inside the wall. At this time, the rubber pad 3 is installed on the top of the gasket 14, and then the top of the rubber pad 3 is brought into contact with the threaded nail body 1, so as to increase the friction between the gasket 14 and the threaded nail body 1. Through the above structure, the rubber pad 3 with large friction is brought into direct contact with the threaded nail body 1, thereby reducing the slippage between the gasket 14 and the threaded nail body 1 due to the small friction between the threaded nail body 1 and the gasket 14 when the threaded nail body 1 is rotated, thereby reducing the difficulty in fitting caused by the small friction between the threaded nail body 1 and the gasket 14.

[0026] like Figures 1 to 4 As shown, the side walls of the plurality of lift pieces 21 are fixed with a plurality of saw teeth 4; the plurality of saw teeth 4 are equidistantly distributed along the length of the lift piece 21. When working, as the plurality of lift pieces 21 are expanded and extended to the inside of the wall, the plurality of saw teeth 4 on the side of the lift piece 21 will move with the expansion of the lift piece 21. At this time, the plurality of saw teeth 4 will also extend to the inside of the wall and then come into contact with the wall. Through the above structure, the plurality of saw teeth 4 can be connected to the wall in conjunction with the lift piece 21, thereby reducing the situation in which the side of the lift piece 21 is too smooth and causes it to become loose inside the wall.

[0027] like Figures 1 to 3As shown, a plurality of leakage holes 5 are provided in the middle of the expansion sheet 12; the plurality of leakage holes 5 are equidistantly distributed along the length of the expansion sheet 12, and are staggered with the notch 2. During operation, as the expansion sheet 12 extends to the interior of the wall, debris inside the wall will enter the interior of the expansion sheet 12 through the notch 2 and the crack on the surface of the expansion sheet 12. As the amount of debris increases, the interior of the expansion sheet 12 may be clogged. At this time, by providing a plurality of leakage holes 5 on the surface of the expansion sheet 12, a portion of the debris inside the expansion sheet 12 may flow out from the middle of the leakage holes 5. Through the above structure, the accumulation of excessive debris inside the expansion sheet 12, which may cause the interior of the expansion sheet 12 to be clogged, may be reduced.

[0028] like Figure 3 As shown, the bottoms of the plurality of lift pieces 21 are all fixedly connected with fixing hooks 6; the fixing hooks 6 are arranged facing the outside of the expansion piece 12. When working, by setting the fixing hooks 6 at the ends of the lift pieces 21, when the lift pieces 21 expand, the fixing hooks 6 will also be synchronously inserted into the interior of the wall. Through the above structure, the connection between the lift pieces 21 and the wall is further increased.

[0029] like Figure 2 As shown, the middle thread of the screw body 1 contacts the inner wall of the expansion piece 12. Through the above arrangement, when the screw body 1 rotates, the expansion piece 12 is driven to expand, so that the expansion piece 12 is deformed inside the wall to achieve the fixation of the multi-layer wall.

[0030] During operation, the exterior wall structure, thermal insulation layer, plaster layer, finishing layer and overall reinforcement coating are arranged in sequence. When the arrangement is completed, the threaded nail body 1 can be installed on the surface of the overall reinforcement coating. At this time, as the threaded nail body 1 is placed on the surface of the overall reinforcement coating, the threaded nail body 1 is twisted. As the threaded nail body 1 is twisted, the expansion sheet 12 contacts the overall reinforcement coating. At this time, as the threaded nail body 1 is twisted, the expansion sheet 12 will successively destroy the overall reinforcement coating, the finishing layer, the plaster layer, the thermal insulation layer and the exterior wall structure. At this time, as the expansion sheet 12 destroys these wall surfaces, the expansion sheet 12 will also extend to the wall surface along with the threaded nail body 1. , at this time, the gasket 14 and the overall reinforcement coating are in contact with each other. At this time, as the screw nail body 1 rotates and the wall restricts the expansion piece 12, the thread in the middle of the screw nail body 1 will stretch the expansion piece 12 and then form a barb. At this time, the screw nail body 1 can be fixed to the inside of the wall. At the same time, the fixation of the multi-layer wall can be achieved through multiple screw nail bodies 1. As the screw nail body 1 is rotated, the screw nail body 1 and the expansion piece 12 are extended to the inside of the wall. At this time, as the thread in the middle of the screw nail body 1 continuously contacts the inner side wall of the expansion piece 12, the flap 21 in the middle of the expansion piece 12 will expand with the expansion of the expansion piece 12. The screw body 1 is expanded and expanded, and then the multiple flaps 21 and the expansion piece 12 can be expanded at the same time, and then the multi-layer wall is fixed. As the top of the screw body 1 is rotated, when the screw body 1 and the top of the gasket 14 are in contact, the gasket 14 can cooperate with the screw body 1 and the expansion piece 12 to fix the screw body 1 inside the wall. At this time, the rubber pad 3 is installed on the top of the gasket 14, and then the top of the rubber pad 3 is in contact with the screw body 1, so as to increase the friction between the gasket 14 and the screw body 1. As the multiple flaps 21 are expanded and extended to the inside of the wall, the multiple serrations 4 on the side of the flap 21 will be The expansion piece 21 moves with the expansion, and the multiple saw teeth 4 will also extend to the inside of the wall and then come into contact with the wall. As the expansion piece 12 extends to the inside of the wall, the debris inside the wall will enter the inside of the expansion piece 12 through the slot 2 and the crack on the surface of the expansion piece 12. As the amount of debris increases, the inside of the expansion piece 12 may be blocked. At this time, multiple leakage holes 5 are provided on the surface of the expansion piece 12, so that part of the debris inside the expansion piece 12 can flow out from the middle of the leakage hole 5. A fixing hook 6 is provided at the end of the expansion piece 21. At this time, as the expansion piece 21 expands, the fixing hook 6 will also be synchronously inserted into the inside of the wall.
