TECHNICAL FIELD
[0001] The application relates to the technical field of composite felt sheets, in particular to a special anti-cracking composite felt sheet for outer walls. BACKGROUND
[0002] Composite felt sheets are usually attached to the outer walls of buildings to improve the heat and sound insulation performance of the outer walls and prevent water seepage. In buildings, in order to prevent water leakage, waterproof treatment is usually performed on the outer walls, and the most common method is to lay felt sheets on the walls. In actual scenarios, due to the large area of the walls, multiple felt sheets are usually needed to be spliced together to form a whole. The splicing is usually connected by adhesion. However, since the adhesion is mostly overlapping, the adhesion part is prone to come off when a pulling force is generated, resulting in cracking at the adhesion part and affecting the waterproof performance.

[0039] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
[0040] Reference Figures 1-7The utility model provides a special anti-cracking composite felt piece for outer wall, including: felt piece main body 10, first edge 11, second edge 12, third edge 13, fourth edge 14, connecting strip 15, recessed strip 16, slot 17, limiting protrusion 18, limiting groove 19, glue injection block 20, glue injection port 21. Felt piece main body 10 is the felt piece of multilayer composite (the specific composite structure can refer to the Chinese patent document with the publication number CN214563541U), and the felt piece main body 10 is rectangular structure, has adjacent first edge 11 and second edge 12, and adjacent third edge 13 and fourth board, when two felt pieces are spliced, the first edge 11 of a felt piece is connected with the third edge 13 of another felt piece or the second edge 12 of a felt piece is connected with the fourth edge 14 of another felt piece. The connecting strip 15 is fixedly connected on the first board and the second edge 12, and the recessed strip 16 is fixedly connected on the third edge 13 and the fourth board. The recessed strip 16 is provided with the slot 17 for the insertion of the connecting strip 15. The upper and lower ends of the connecting strip 15 are provided with the limiting protrusion 18 extending along the connecting strip 15, and the upper and lower sidewalls of the slot 17 are provided with the limiting groove 19 for the embedding of the limiting protrusion 18. When the connecting strip 15 is embedded in the recessed slot 17, the limiting protrusion 18 is embedded in the limiting groove 19.
[0041] Two recessed strips 16 are connected with glue injection block 20 at one end close to each other, two recessed strips 16 are connected through glue injection block 20, and glue injection port 21 is formed in glue injection block 20. Two upper and lower glue injection blocks 22 are arranged in glue injection port 21, and two glue injection blocks 22 are arranged at the positions of the upper slot 17 and the lower slot 17 respectively. The installation hole 23 is formed in the glue injection block 22, and the glue injection nozzle 31 is rotatably connected in the glue injection port 21 and passes through the installation hole 23.
[0042] Two side walls of the slot 17 are provided with a channel 24 for the glue to flow into, and the inner cavity 25 is provided in the glue distribution block 22. The channel 24 on the upper slot 17 extends to the inner cavity 25 of the upper glue distribution block 22 and communicates with the inner cavity 25. The channel 24 on the lower slot 17 extends to the inner cavity 25 of the lower glue distribution block 22 and communicates with the inner cavity 25. The glue can flow into the channel 24 through the inner cavity 25. The glue injection nozzle 31 is a cylindrical structure, and two glue supply holes 26 are provided on the side wall of the glue injection nozzle 31. The through hole 27 is provided on the side wall of the mounting hole 23 and communicates with the inner cavity 25. The two glue supply holes 26 are respectively consistent with the two through holes 27 in height. The glue injection nozzle 31 is rotated to make one glue supply hole 26 coincide with one through hole 27, or the other glue supply hole 26 coincide with the other through hole 27. The limiting protrusion 18 is smaller than the limiting groove 19 in cross section. When the limiting protrusion 18 is embedded in the limiting groove 19, the glue injection space for the glue to flow is formed. When the glue flows into the inner cavity 25 of the glue distribution block 22 through the through hole 27, the glue flows into the limiting groove 19 through the channel 24. At this time, the glue injection space for the glue to flow is formed between the limiting protrusion 18 and the limiting groove 19. The glue flows in the glue injection space until the glue injection space is filled. The opening of the channel 24 is located in the glue injection space.
[0043] The upper end of the glue injection nozzle 31 penetrates the glue injection block 20 and is fixedly connected with the rotating knob 28. The positioning protrusion 29 is fixedly connected to the side wall of the glue injection nozzle 31. The positioning groove 30 is provided on the side wall of the mounting hole 23. The positioning protrusion 29 is embedded in the positioning groove 30. The glue injection nozzle 31 is rotated to make the positioning protrusion 29 move in the positioning groove 30. The positioning protrusion 29 has two limit positions in the positioning groove 30. When the positioning protrusion 29 abuts against the side wall of the positioning groove 30, when it is in one limit position, one glue supply hole 26 coincides with one through hole 27. When it is in the other limit position, the other glue supply hole 26 coincides with the other through hole 27. It is convenient to position.
[0044] Working process or use method:
[0045] 1. When the felt pieces need to be spliced, the connecting strip 15 is inserted into the slot 17. At this time, the limiting protrusion 18 is also embedded in the limiting groove 19. When the two slots 17 on one felt piece are connected with the connecting strip 15, the connecting strip 15 and the slot 17 are glued by injecting glue into the glue injection nozzle 31.
[0046] 2. When the glue is injected into the glue injection nozzle 31, the glue injection nozzle 31 is located in one limit position. One glue supply hole 26 coincides with the through hole 27 on the lower glue distribution block 22. At this time, the glue flows into the inner cavity 25 of the lower glue distribution block 22 through the through hole 27, and then flows into the lower limiting groove 19 through the channel 24, and fills the glue injection space formed by the lower limiting groove 19 and the limiting protrusion 18.
[0047] 3. After the glue is injected into the lower limiting groove 19, rotate the glue injection nozzle 31 to another extreme position, so that a glue supply hole 26 coincides with the through hole 27 on the upper glue distribution block 22, and continue to inject glue so that the glue fills the glue injection space formed by the upper limiting groove 19 and the limiting protrusion 18, thus completing the splicing of the felt sheet.
