[0023] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0024] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a protective edge groove structure for waterproof membrane is used to protect the reserved edge of the waterproof membrane when it is installed to the edge position. It includes a protective body 1 formed by folding it in half. The protective body 1 includes an upper protective sheet 2 and a lower protective sheet 3 formed by folding it in half. A groove 4 is formed between the upper protective sheet 2 and the lower protective sheet 3 for placing the reserved edge of the waterproof membrane. The two ends of the two protective bodies 1 can be spliced together to form a whole.
[0025] This utility model proposes a protective edge-guarding groove structure for standardized waterproof membranes. Its main function is to protect the pre-reserved edges of the waterproof membrane during installation. The protective body 1 is a folded, integrally formed component, resulting in better structural integrity, reducing potential seams, and improving the protective effect.
[0026] The protective body 1 is folded in half to form an upper protective sheet 2 and a lower protective sheet 3. The upper protective sheet 2 and the lower protective sheet 3 are the main components of the protective body 1, and together they form the space for placing the reserved edge of the waterproof membrane.
[0027] A groove 4 is formed between the upper protective sheet 2 and the lower protective sheet 3. This groove 4 is specifically designed to accommodate the reserved edge of the waterproof membrane. By placing the reserved edge of the waterproof membrane in the groove 4, the edge of the waterproof membrane can be effectively protected, preventing it from being damaged by external factors or affecting its waterproof performance.
[0028] The two ends of the two protective main bodies 1 can be spliced together to form a whole. In practical applications, the length of the protective structure can be extended as needed, and multiple protective main bodies 1 can be spliced together to meet the protection requirements of edges of different lengths, thereby improving the versatility and flexibility of the structure.
[0029] When the waterproof membrane is installed to the edge, the reserved edge portion of the waterproof membrane is placed into the groove 4 formed between the upper protective sheet 2 and the lower protective sheet 3 of the protective body 1. Due to the presence of the groove 4, the reserved edge of the waterproof membrane can be stably fixed therein, preventing it from moving at will or being scratched or bumped by external objects.
[0030] The upper protective sheet 2 and the lower protective sheet 3 protect the reserved edges of the waterproof membrane placed in the slot 4. The upper protective sheet 2 prevents falling debris from damaging the edges of the waterproof membrane, while the lower protective sheet 3 prevents the edges of the waterproof membrane from directly contacting the ground or other substrates, reducing the impact of friction, moisture, and other factors on the waterproof performance of the edges of the waterproof membrane.
[0031] When the edge requiring protection is long, the ends of two protective bodies 1 can be spliced together. The spliced protective bodies 1 form a continuous whole, providing comprehensive and effective protection for the long, reserved edge of the waterproof membrane, ensuring that the waterproof performance of the entire edge area is unaffected. Splicing methods can include common methods such as snap-fit, plug-in, and adhesive, depending on the design requirements, as long as the spliced structure is stable and secure.
[0032] Combination Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, one end of the protective body 1 is provided with a splicing protrusion 5, and the other end of the protective body 1 is provided with a splicing groove 6 that matches the splicing protrusion 5. The two protective bodies 1 are connected and spliced into a whole by inserting the splicing protrusion 5 into the splicing groove 6.
[0033] Specifically, a splicing protrusion 5 is provided at one end of the protective body 1. The splicing protrusion 5 protrudes outward from the end of the protective body 1, and its shape and size are carefully designed to ensure a stable and reliable connection with the splicing groove 6. A splicing groove 6 is provided at the other end of the protective body 1, and the splicing groove 6 matches the splicing protrusion 5. The splicing groove 6 is a recessed structure opened at the end of the protective body 1, and its internal shape and size match the external shape and size of the splicing protrusion 5, so that the splicing protrusion 5 can be smoothly inserted into it.
[0034] When two protective bodies 1 need to be spliced into a whole, align the end of one protective body 1 with the splicing protrusion 5 with the end of the other protective body 1 with the splicing groove 6. Then, align the splicing protrusion 5 with the splicing groove 6 and slowly insert the splicing protrusion 5 into the splicing groove 6. During the insertion process, because the shapes and sizes of the splicing protrusion 5 and the splicing groove 6 match, a certain amount of friction and locking force will be generated between them, allowing the splicing protrusion 5 to be tightly embedded in the splicing groove 6.
[0035] Once the splicing protrusion 5 is fully inserted into the splicing groove 6, the two protective bodies 1 are joined together as a single unit via a snap-fit connection. This splicing method utilizes the mechanical engagement between the splicing protrusion 5 and the splicing groove 6, giving the assembled structure a certain degree of stability and robustness. Under normal use, the assembled protective bodies 1 will not easily separate, effectively withstanding external pressure and tension, ensuring the integrity and functionality of the entire protective structure.
[0036] Combination Figure 4 , Figure 5 , Figure 8 As shown, the upper protective plate 2 has matching upper extension block 7 and lower extension block 8 at both ends, and the two protective bodies 1 are spliced together into a whole by the upper extension block 7 and lower extension block 8.
[0037] Specifically, one end of the upper protective sheet 2 is provided with an upper extension block 7, which extends outward from that end of the upper protective sheet 2. The upper extension block 7 has a certain shape, size, and thickness, and its shape and size design must meet the requirements of matching and overlapping with the lower extension block 8 to ensure the stability and sealing of the two protective bodies 1 when spliced. The material of the upper extension block 7 is the same as that of the upper protective sheet 2, ensuring the material consistency and structural strength of the overall structure.
[0038] The other end of the upper protective sheet 2 is provided with a lower extension block 8, which is also a structure extending outward from this end of the upper protective sheet 2. The shape, size, and thickness of the lower extension block 8 are adapted to the upper extension block 7, so that it can be tightly overlapped with the upper extension block 7 when the two protective bodies 1 are spliced. The connection between the lower extension block 8 and the upper protective sheet 2 is stable, ensuring that it will not easily fall off after splicing.
[0039] When it is necessary to splice two protective bodies 1 into a whole, first bring the two protective bodies 1 close together, so that the end of one protective body 1 with the upper extension block 7 is opposite to the end of the other protective body 1 with the lower extension block 8.
[0040] Place the upper extension block 7 on the lower extension block 8, or place the lower extension block 8 on the upper extension block 7, to complete the overlapping action. Since the upper extension block 7 and the lower extension block 8 match each other, a contact surface is formed during the overlapping process. This overlapping method can prevent large gaps from appearing after the two protective bodies 1 are spliced.
[0041] By overlapping and splicing the upper extension block 7 and the lower extension block 8, the two protective main bodies 1 are connected into a whole. This splicing method is simple and easy to implement, while ensuring that the spliced structure has a certain degree of stability and sealing. In practical applications, such as when protecting the edges of waterproof membranes, the spliced overall structure can effectively block external moisture, dust, etc. from entering, providing reliable protection for the edges of the waterproof membrane and ensuring the normal use and waterproof performance of the waterproof membrane.
[0042] Combination Figure 4 , Figure 5 , Figure 8 As shown, a lower protrusion 71 is provided on the outer bottom of the upper extension block 7, and a lower groove 72 is formed on the inner bottom of the upper extension block 7. An upper protrusion 81 matching the lower groove 72 is provided on the outer top of the lower extension block 8, and an upper groove 82 matching the lower protrusion 71 is formed on the inner top of the lower extension block 8. The two protective bodies 1 are connected and spliced into a whole by the lower protrusion 71 and the upper groove 82 and the upper protrusion 81 and the lower groove 72 through the slot.
[0043] Specifically, the lower extension block 7 has a raised structure located on the outer bottom of the upper extension block 7. The shape of the lower protrusion 71 must match the upper groove 82 to achieve a tight fit. The lower groove 72 is a recessed area on the inner bottom of the upper extension block 7. The lower groove 72 fits into the upper protrusion 81 on the top of the lower extension block 8, thus playing a role in positioning and fixing during assembly.
[0044] The lower extension block 8 is located at the other end of the upper protective sheet 2 and works in conjunction with the upper extension block 7 to complete the splicing of the two protective bodies 1. Through its special structure, it achieves a slot connection with the upper extension block 7.
[0045] The upper protrusion 81 is located on the top outer side of the lower extension block 8, corresponding to the lower groove 72 at the bottom of the upper extension block 7. The shape and size of the upper protrusion 81 match the lower groove 72, allowing it to be accurately inserted into the lower groove 72 during splicing, thus enhancing the splicing strength.
[0046] The upper groove 82 is formed on the top inner side of the lower extension block 8 and is adapted to the lower protrusion 71 at the bottom of the upper extension block 7. The shape, size and depth of the upper groove 82 are precisely designed to ensure that the lower protrusion 71 can be smoothly inserted into it to achieve a stable slot connection.
[0047] When it is necessary to splice two protective bodies 1 into a whole, bring the two protective bodies 1 close together, so that the end of one protective body 1 with the upper extension block 7 is opposite to the end of the other protective body 1 with the lower extension block 8.
[0048] Align the upper extension block 7 and the lower extension block 8 roughly so that the lower protrusion 71 corresponds to the upper groove 82 and the upper protrusion 81 corresponds to the lower groove 72.
[0049] Applying a certain pressure to the two protective bodies 1 causes the lower protrusion 71 to gradually embed into the upper groove 82, while the upper protrusion 81 also gradually inserts into the lower groove 72. Since the shapes and sizes of the lower protrusion 71 and the upper groove 82, as well as the upper protrusion 81 and the lower groove 72, match each other, a certain friction and clamping force will be generated during the engagement process, so that the upper extension block 7 and the lower extension block 8 are tightly connected together.
[0050] The two protective bodies 1 are spliced into a single unit through the interlocking connections between the lower protrusion 71 and the upper groove 82, as well as between the upper protrusion 81 and the lower groove 72. This interlocking connection method offers high stability and reliability, effectively preventing the two protective bodies 1 from loosening or separating after splicing. In practical applications, such as when protecting the edges of waterproof membranes, the spliced integrated structure provides reliable protection for the edges of the waterproof membrane, preventing external moisture, dust, and other contaminants from entering, thus ensuring the normal use and waterproof performance of the waterproof membrane.
[0051] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protective body 1 is a 1m*1m square piece that is folded in half to form a 0.5m*1m U-shaped slot structure.
[0052] Specifically, the protective body 1 is initially composed of a square piece with a size of 1 meter (1M) × 1 meter (1M). The square piece has a specific material, and the choice of material will be determined according to the actual use scenario and protection requirements. For example, it may use materials with certain strength, flexibility and corrosion resistance to ensure that the structure can maintain the stability and functional integrity during subsequent folding and use.
[0053] Fold this 1m x 1m square piece in half. The fold is made along one edge of the square, changing its shape. The folded piece forms a 0.5m x 1m U-shaped slot structure. Here, 0.5m refers to the width of the U-shaped slot structure in the folding direction; since the original 1m wide square is folded, the width becomes half of its original size; 1m maintains the original length of the square before the fold. The U-shaped slot structure has an opening perpendicular to the folded edge, creating a space inside that can accommodate other objects. For example, when used to protect the edges of waterproof membrane, the edge of the waterproof membrane can be placed inside this U-shaped slot.
[0054] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, double-sided adhesive strips are affixed to the top and bottom of the long side and the short side openings of the slot 4 of the protective body 1. The reserved edge of the waterproof membrane is inserted into the slot 4 and fixed by the double-sided adhesive strips.
[0055] Specifically, the slot 4 has a certain length, width, and depth to accommodate the reserved edge of the waterproof membrane. The slot 4 has a long side and two short sides, which together form the opening of the slot, making it easy to insert the reserved edge of the waterproof membrane.
[0056] Double-sided adhesive strips are affixed to the top and bottom of the openings on the long side and both short sides of the card slot 4. These double-sided adhesive strips have a certain width and length, and are typically made of a material with good adhesion, maintaining stable adhesion under various environments. The double-sided adhesive strips are tightly adhered to the top and bottom surfaces of the card slot openings, forming an adhesive layer used to secure the reserved edges of the waterproof membrane inserted into the card slot.
[0057] When it is necessary to protect the edges of the waterproof membrane, insert the reserved edge of the waterproof membrane into the slot 4 along the opening of the slot 4. Since the size of the slot 4 is adapted to the reserved edge of the waterproof membrane, the reserved edge of the waterproof membrane can smoothly enter the slot 4.
[0058] As the pre-existing edge of the waterproof membrane is inserted, it comes into contact with the double-sided adhesive strips attached to the top and bottom of the opening of slot 4. The adhesive properties of the double-sided adhesive strips immediately take effect, firmly adhering the pre-existing edge of the waterproof membrane to the slot 4. The double-sided adhesive strips are applied to both the top and bottom of the openings on the long side and both short sides of the slot, securing the pre-existing edge of the waterproof membrane from multiple directions and ensuring that it will not easily fall off from the slot 4.
[0059] With the double-sided adhesive strip securing it, the pre-reserved edge of the waterproof membrane is stably installed inside the slot 4. In this way, the protective body 1 can effectively protect the pre-reserved edge of the waterproof membrane, preventing it from being damaged by external factors, such as scratches and collisions, and avoiding deformation or loss of waterproof performance due to environmental factors such as wind and sun exposure, thereby ensuring the integrity and reliability of the entire waterproof system.
[0060] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protective body 1 is made of stainless steel.
[0061] Specifically, the entire protective body 1 is made of stainless steel. Stainless steel is an alloy material with many excellent properties. It is composed of elements such as iron, chromium, and nickel mixed in a certain proportion. Different element ratios and processing techniques will give stainless steel different properties. In this structure, the stainless steel material selected for the protective body 1 has been carefully chosen to meet specific usage requirements.
[0062] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the waterproof membrane is being installed, the edge of the waterproof membrane can be separated from the protective body 1 by tearing off the double-sided adhesive strip.
[0063] Specifically, during the initial construction preparation phase, the edges of the waterproof membrane and the protective body 1 are connected and fixed in a specific way. The protective body 1 is equipped with a structure for fixing the edges of the waterproof membrane. Double-sided adhesive strips, as the key connecting medium, are pre-installed at the contact points between the protective body 1 and the edges of the waterproof membrane, such as on suitable locations like the upper and lower surfaces of any slot openings on the protective body 1, to achieve a tight bond between the edges of the waterproof membrane and the protective body 1.
[0064] In the initial stage of waterproof membrane construction, the edge of the waterproof membrane is placed in the corresponding position on the protective body 1, ensuring full contact between the edge of the waterproof membrane and the double-sided adhesive strip adhered to the protective body 1. Due to the double-sided adhesiveness of the strip, the edge of the waterproof membrane and the protective body 1 are immediately bonded together, forming a relatively stable integral structure. This bonding method effectively fixes the edge of the waterproof membrane, preventing displacement or detachment during construction, and ensuring the quality and stability of the waterproof membrane construction.
[0065] When further construction work is required on the waterproof membrane (such as splicing it with other waterproof membranes, performing local repairs, etc.) or when the protective body 1 needs to be removed, the construction worker only needs to gently peel off the double-sided adhesive strip. Since the adhesion between the double-sided adhesive strip and the protective body 1 and the edge of the waterproof membrane is achieved through adhesive, the adhesion between the adhesive and the adhered objects is gradually overcome during the peeling process. As the double-sided adhesive strip separates, the adhesion between the edge of the waterproof membrane and the protective body 1 is broken, and the two are separated. This separation method is simple and convenient, does not cause significant damage to the waterproof membrane and the protective body 1, ensures the smooth progress of subsequent construction, and also facilitates the reuse of the protective body 1.
[0066] This invention represents a preferred embodiment of the present invention, but its scope of protection is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, shall be covered within the scope of protection of this invention.
