Description

Technical Field

[0001] This application relates to the field of building materials technology, and more specifically, to a waterproof felt board for exterior walls. Background Technology

[0002] In modern architecture, to ensure the insulation, waterproofing, and moisture-proofing of building exterior walls, waterproof felt boards are typically installed. These boards are mostly made of rock wool fibers or glass wool, and after pressing, a waterproofing material is applied to their surface. This process protects the exterior walls from leaks caused by prolonged exposure to the elements. However, existing waterproof felt boards are usually installed by screws or adhesives, with workers joining adjacent boards together to minimize gaps and ensure overall waterproofing. However, due to the varying standards of board processing, a complete seal between boards is difficult, creating gaps that allow rainwater to erode the exterior wall and compromise waterproofing. Therefore, waterproof adhesive or foam is typically used to fill these gaps. However, manual application of waterproof adhesive makes it difficult to determine if the sealant is completely filled; if not, rainwater can still seep in through the gaps.

[0003] Therefore, a special waterproof felt board for exterior walls is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a waterproof felt board for exterior walls, comprising: a felt board body, the felt board body having a rectangular structure, having a first side and a second side connected together, and a third side and a fourth side connected together; a first connecting strip fixed to the third side and the fourth side, extending along the third side and the fourth side; a second connecting strip fixed to the first side and the second side, extending along the first side and the second side; the first connecting strip having two oppositely arranged side plate portions, with an adhesive injection groove formed between the two side plate portions; the second connecting strip having a fixing plate portion fixed to the felt board body, and a connecting insert plate fixedly connected to the fixing plate portion and extending along the fixing plate portion, with an adhesive injection hole provided on the side plate portion, the connecting insert plate being inserted into the adhesive injection groove to connect the two felt board bodies.

[0006] When installing two felt board bodies, the first and second connecting strips are used. The corresponding second connecting strips are inserted into the glue injection groove to connect them. Glue is then introduced into the glue injection groove through the glue injection hole to seal the gap and make it waterproof.

[0007] Furthermore, the glue injection holes are located on the side panel away from the exterior wall surface. There are two glue injection holes, which are respectively located at the middle of the third and fourth sides. The glue injection groove is slidably connected with two sets of sliding buckles that slide along the third and fourth sides respectively. Each set of sliding buckles has two buckles, which are located on both sides of the glue injection hole.

[0008] The sliding buckle is designed so that when glue is introduced into the glue injection groove, it will push the sliding buckle, causing it to move and limit the two felt board bodies to ensure a stable connection.

[0009] Furthermore, the connecting plate includes a first part extending along the first side and a second part extending along the second side. Both the first part and the second part can be connected to connecting blocks located on both sides. The connecting blocks are provided with buckle grooves, and the sliding buckle is embedded into the buckle groove for limiting.

[0010] By using the connecting block and the locking groove, when the glue in the injection groove is completely filled, the sliding buckle will be pushed, causing the sliding buckle to be embedded in the locking groove for limiting.

[0011] Furthermore, the sliding buckle includes a plate portion and an embedded portion fixed to the plate portion. The plate portion is slidably disposed in the glue injection groove. When the connecting plate is inserted into the glue injection groove, the sliding buckle fits against the connecting plate, and the embedded portion is directly opposite the buckle groove.

[0012] With the set plate and the embedded part, when glue is introduced into the glue injection groove, the glue will push the plate, causing the sliding buckle to move.

[0013] Furthermore, a sliding groove is provided in the first connecting strip, and a sliding strip is fixedly provided on the sliding buckle, which is embedded in the sliding groove and slides.

[0014] With the sliding bar and sliding groove set, when the sliding buckle slides, the sliding bar will slide within the sliding groove.

[0015] Furthermore, an elastic element is provided inside the sliding groove, and the two ends of the elastic element are fixedly connected to the sliding strip and the side wall of the sliding groove, respectively.

[0016] The elastic element is designed to position the sliding buckle on both sides of the glue injection hole. At the same time, when the connecting plate and the connecting block are inserted into the glue injection groove, the sliding buckle and the connecting block are staggered to avoid obstruction.

[0017] Furthermore, a sealing head is installed at the injection hole, and a spring is connected between the sealing head and the side plate. The two ends of the spring are fixedly connected to the sealing head and the side plate, respectively.

[0018] With the addition of a sealing head and a spring, when glue is being filled into the glue injection tank through the injection hole, the sealing head will not block the glue. When no more glue is being filled, the sealing head will prevent the glue from flowing out.

[0019] Furthermore, a transparent observation window is provided on the side panel, located at the sliding track of the sliding buckle, allowing observation of the position of the sliding buckle.

[0020] The observation window allows you to observe the position of the sliding buckle and, based on that position, the glue filling area in the glue injection tank, thus determining whether the filling is complete.

[0021] The beneficial effects of this application are as follows:

[0022] 1. When installing two felt board bodies, the corresponding connecting plates are inserted into the glue injection groove through the first and second connecting strips to connect them. Glue is then introduced into the glue injection groove through the glue injection hole to seal the gap and waterproof the area.

[0023] 2. The sliding buckle is designed so that when glue is introduced into the glue injection groove, it will push the sliding buckle, causing it to move and embed into the buckle groove for limiting, thus ensuring a stable connection.

[0024] 3. The observation window allows you to observe the glue filling range in the glue injection tank by checking the position of the sliding buckle, thus ensuring complete filling. Attached Figure Description

[0041] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0042] Reference Figure 1-7 A waterproof felt board for exterior walls includes: a felt board body 10, a first side 11, a second side 12, a third side 13, a fourth side 14, a side panel 15, a fixing plate 16, a first connecting strip 17 and a second connecting strip 18, a connecting insert plate 21, and an injection hole 23. The felt board body 10 is a felt board made of rock wool fiber or glass wool, and has a rectangular board structure. The felt board body 10 is laid on the exterior wall for waterproofing. The felt board body 10 has connected first side 11 and second side 12, as well as connected third side 13 and fourth side 14. When laying the felt board body 10, for two felt board bodies 10 arranged side to side, the fourth side 14 of the left felt board body 10 is pressed against the first side 11 of the right felt board body 10; for two felt board bodies 10 arranged vertically, the second side 12 of the upper felt board body 10 is pressed against the third side 13 of the lower felt board body 10, and they are spliced ​​together. A first connecting strip 17 is fixed to the felt board body 10, extending along the third side 13 and the fourth side 14 to form an L-shape. Similarly, a second connecting strip 18 is also fixed to the felt board body 10, extending along the first side 11 and the second side 12. The first connecting strip 17 has two opposing side plate portions 15, forming an injection groove 19 between them. The main bodies of the first connecting strip 17 and the second connecting strip 18 can be made of rigid plastic. The second connecting strip 18 includes a fixing plate portion 16 fixed to the first side 11 and the second side 12, and a connecting insert plate 21 is fixedly disposed on the fixing plate portion 16. When two felt board bodies 10 are joined, the connecting insert plate 21 is inserted into the corresponding injection groove 19 for connection.

[0043] Two glue injection holes 23 are provided on the side panel 15 away from the exterior wall, respectively aligned with the middle positions of the third side 13 and the fourth side 14. After the connecting plate 21 is inserted into the glue injection groove 19, glue is injected into the glue injection groove 19 through the glue injection holes 23, causing the glue to gradually flow from the glue injection holes 23 to both sides until the entire glue injection groove 19 is filled. To ensure that the glue fills the entire glue injection groove 19, two sets of sliding buckles 24 are slidably arranged within the glue injection groove 19, sliding along the third side 13 and the fourth side 14 respectively. Each set of sliding buckles 24 has two buckles, located on either side of the glue injection hole 23. When glue is injected from the glue injection hole 23, the glue pushes the sliding buckles 24. The sliding buckle 24 includes a plate portion that slides within the glue injection groove 19 and an embedded portion fixed to the plate portion. When the glue flows to the board section, it causes the sliding buckle 24 to move away from the glue injection hole 23. An observation window 26, made of transparent plastic, is provided in the area of ​​the side panel 15 away from the glue injection hole 23. The observation window 26 is located along the sliding path of the sliding buckle 24, allowing observation of the position of the sliding buckle 24. An indicator strip 30 is fixedly connected to the sliding buckle 24, and the indicator strip 30 has an indicator area, which is observed through the observation window 26. When the glue completely fills the glue injection tank 19, the sliding buckle 24 moves, and the indicator area of ​​the indicator strip 30 can be observed through the observation window 26, ensuring complete glue filling.

[0044] The connecting plate 21 has a first part on the first side 11 and a second part on the second side 12. Connecting blocks 22 are fixedly connected to both ends of the first part and the second part. The connecting blocks 22 are provided with buckle grooves 25, so that when the glue injection groove 19 is completely filled, the insert of the sliding buckle 24 will be inserted into the buckle groove 25, thereby limiting the two felt board bodies 10.

[0045] A sliding strip 27 is fixed to the sliding buckle 24, and a sliding groove 28 is provided on the first connecting strip 17. The sliding strip 27 is slidably disposed in the sliding groove 28, and an elastic element 29, which can be a spring, is provided in the sliding groove 28. The two ends of the elastic element 29 are fixed to the sliding strip 27 and the side wall of the sliding groove 28, respectively. When the connecting plate 21 and the connecting block 22 are inserted into the glue injection groove 19, the sliding buckle 24 and the connecting block 22 are misaligned to avoid obstruction.

[0046] A sealing head 31 is provided at the glue injection hole 23. A spring 20 is connected between the sealing head 31 and the side plate 15. The two ends of the spring 20 are fixedly connected to the sealing head 31 and the side plate 15 respectively. When glue is filled into the glue injection groove 19 through the glue injection hole 23, the sealing head 31 will not block the glue. When no more glue is filled, the sealing head 31 will block the glue from flowing out.

[0047] Working process or usage method:

[0048] 1. When it is necessary to lay waterproof felt boards on the exterior wall, the felt board bodies 10 are joined together for support. For two felt board bodies 10 arranged left and right, the fourth side 14 of the left felt board body 10 is close to the first side 11 of the right felt board body 10; for two felt board bodies 10 arranged top and bottom, the second side 12 of the upper felt board body 10 is close to the third side 13 of the lower felt board body 10, and they are spliced ​​together.

[0049] 2. Waterproof glue or waterproof foam agent is filled into the glue injection groove 19 through the glue injection hole 23. When the waterproof glue fills the position of the sliding buckle 24, it will push the sliding buckle 24 to move. Then, the indicator bar 30 moves to the position of the observation window 26 by moving the sliding bar 27 and the sliding groove 28 to the left and right. By observing the indicator area of ​​the indicator bar 30, when the entire indicator area can be observed, the glue injection groove 19 is completely filled.

[0050] 3. As the sliding buckle 24 moves, the insert part will be inserted into the buckle groove 25, thereby limiting the connection between the two felt board bodies 10, ensuring the connection strength between the felt board bodies 10, and further improving the stability of the installation.
