Description

Technical Field

[0001] The utility model relates to the technical field of building waterproofing, and more specifically to a molded waterproof additional layer. Background Art

[0002] Building waterproofing projects involve many parts of buildings (structures), such as basements, walls, floors, walls, roofs, etc. Its function is to prevent the leakage of rainwater and water for production and life and the erosion of groundwater within the designed durability of the building or structure, ensure that the building structure and internal space are not damaged, and provide people with a comfortable and safe living space environment.

[0003] Waterproofing membranes are factory-made, uniformly thick, and flexible waterproof materials that can be rolled into rolls. They are a key component of building waterproofing materials, accounting for approximately 80% of all building waterproofing materials. Currently, they primarily include three categories: traditional asphalt waterproofing membranes, polymer-modified asphalt waterproofing membranes, and synthetic polymer membranes. The latter two types offer superior overall performance and are the newer waterproofing membranes currently being widely promoted.

[0004] Relevant regulations require that single-layer or laminated waterproofing membranes must be supplemented with additional layers at corners, rainwater inlets, and pipe bases to enhance waterproofing performance. These additional layers are typically made of the same or compatible materials to strengthen the waterproofing layer.

[0005] The current waterproof additional layer method of membrane waterproofing is: clean and polish the nodes to make it easier to lay the membrane there; cut and fold the membrane to make its shape match the shape of the node; lay the cut membrane to make it bonded reliably to form an additional waterproof layer.

[0006] The shortcomings of the current waterproof additional layer practice are: the cleaning and polishing of the nodes are not thorough, leaving hidden dangers for the next step of folding, cutting and paving; the folding and cutting of the membrane are not accurate, and do not fully match the shape of the nodes, leaving hidden dangers for paving; the carcass is disconnected at the cut, the waterproof membrane is discontinuous, and the broken parts are filled with adhesives, and the interface becomes a leakage hazard; the node cleaning and polishing, and the folding and cutting of the membrane are all done manually on site, and the accuracy cannot be guaranteed. Finally, the bonding and paving effect of the waterproof additional layer cannot be guaranteed, leaving a leakage hazard. Utility Model Content

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] Figure 1 Schematic diagram of the structure of the molded waterproof additional layer according to Example 1 of the present utility model;

[0040] like Figure 1 As shown, the molded waterproof additional layer proposed in this embodiment can be used as a waterproof additional layer for the parts of the building to be waterproofed, and can also be used as a shaped covering layer at other locations for waterproofing of rolled materials.

[0041] The additional waterproof layer is an important component of building waterproofing projects. It is mainly used to enhance the waterproof performance of building structures and ensure that the building is not affected by water erosion during long-term use. The additional waterproof layer is usually an additional layer of material added on top of the main waterproof layer. Its purpose is to improve the durability and reliability of the waterproof layer. Depending on the specific construction conditions, some additional layers can be laid on the top of the leveling layer and then attached to the waterproof layer, while some additional layers can be laid on top of the waterproof layer. In both cases, the flat waterproof membrane must be cut and laid. The membrane sometimes does not adhere tightly to the inner and outer corners, resulting in hollowing. It is inevitable to lay joints, which will cause leakage risks. This molded waterproof additional layer is a one-piece cover layer without joints and can be laid in one go.

[0042] According to the "General Specification for Waterproofing of Buildings and Municipal Engineering," additional layers of waterproofing should be applied to flooded areas such as gutters, eaves, skylights, rainwater pipes, and pipe wells extending from the roof. Areas where it's difficult to apply a single sheet of waterproofing material—corners, intersections between facades and planes, rainwater (downspout) outlets, pipe roots, column heads, foundation piers, expansion joints, roof vents, and other locations—need to be reinforced with additional layers of waterproofing. This waterproofing layer can more effectively prevent water infiltration, improving the safety and durability of the building.

[0043] The molded waterproof additional layer includes a molded additional layer having the same outer dimensions as the part to be waterproofed, and the molded additional layer completely covers the waterproof part. The surface of the molded additional layer in contact with the waterproof part is a sticky adhesive surface, which has adhesive properties and can completely adhere the molded additional layer to the waterproof part. The surface of the molded additional layer facing away from the waterproof part is a non-sticky anti-stick surface, which has anti-stick properties and can prevent foreign objects from adhering to this surface.

[0044] Modified additional layers are manufactured in various shapes and styles to suit the specific dimensions of the various waterproofing locations on the construction site. These additional layers are directly bonded to the waterproofing areas, eliminating the need for cutting or folding. This allows for quick and easy installation, seamless construction, and strict waterproofing. A waterproof binder can also be used to assist in the bonding of the additional layers.

[0045] In a specific embodiment of the present invention, the molded additional layer and the waterproof layer at the waterproof portion are made of the same coiled material.

[0046] During construction, the additional layer is generally required to use the same or compatible materials as the waterproof layer. The additional layer is formed according to the material of the membrane to be laid for the waterproof layer.

[0047] In a specific embodiment of the present invention, when the roll material of the waterproof layer is an asphalt waterproof roll, the molded additional layer includes a molded asphalt waterproof roll, the surface in contact with the waterproof part is the asphalt surface of the asphalt waterproof roll, and the surface away from the waterproof part is the surface of the asphalt waterproof roll covered with anti-sticking material.

[0048] The material of asphalt waterproofing membrane is base paper, fiber fabric or fiber felt as the matrix, the heated and melted asphalt is evenly spread on the matrix, the matrix is ​​dipped in asphalt, and then powdered, granular or flaky anti-sticking material is evenly sprinkled on the surface of the undried asphalt-impregnated matrix as a covering layer.

[0049] The additional layer is made of the material of the asphalt waterproof membrane and bonded to the waterproof part. Compared with the additional layer of the asphalt waterproof membrane cut on the surface, it has better waterproof performance.

[0050] The polymer modified asphalt waterproof membrane can also be used to make an additional layer that is formed in one piece and bonded to the waterproof part.

[0051] In a specific embodiment of the present invention, the molded additional layer includes a molded synthetic polymer waterproof membrane, and the surface that contacts the waterproof portion is the adhesive surface of the synthetic polymer waterproof membrane. The adhesive surface can be configured as a cold-bonding surface, a self-adhesive surface, or a hot-air welding surface.

[0052] The material of synthetic polymer waterproof membrane is synthetic rubber, synthetic resin, or a mixture of synthetic rubber and synthetic resin as the base material. Appropriate amounts of chemical additives and fillers are added to the base material, mixed evenly and fully, and then pressed into a flat surface.

[0053] The additional layer is made of a one-piece synthetic polymer waterproof membrane and bonded to the waterproof part. Compared with the additional layer of synthetic polymer waterproof membrane laid on the cut surface, it has better waterproof performance.

[0054] In one embodiment of the present invention, the areas to be waterproofed may include horizontal and vertical downspouts, pile heads, foundation piers, exterior column heads, and exterior column bases. The formed additional layer completely covers the internal and external corners of the waterproof area and extends to the wall at the internal and external corners. The edges of the additional layer should meet the requirement to cover the wall, and the extension width of the additional layer is generally 250 mm.

[0055] In a specific embodiment of the present invention, taking a square horizontal drain outlet as an example, a horizontal drain outlet refers to a drain outlet whose drain outlet is horizontal or approximately horizontal with the ground. Figure 1 As shown, the formed additional layer includes a square cylindrical paving layer 11 with the same internal shape and size as the downspout, the front and rear ends of the square cylindrical paving layer 11 are open, a bottom paving layer 12 is provided at the front end of the lower side wall of the square cylindrical paving layer 11, and a wall paving layer 13 is provided at the outer periphery of the front end of the square cylindrical paving layer 11, and the wall paving layer 13 is vertically connected to the bottom paving layer 12.

[0056] During paving, the square tube paving layer 11 is bonded to the inner wall of the downspout, the bottom paving layer 12 is bonded to the bottom surface outside the water inlet end of the downspout, and the wall paving layer 13 is bonded to the wall surface outside the water inlet end of the downspout. The front end of the square tube paving layer 11 is the water inlet end, and the rear end is the water outlet end.

[0057] The formed additional layer is laid just on the square-mouthed horizontal drain outlet. The corners should be close to the negative and positive corners of the base layer, and it should be fully adhered to without any hollowing or twisting.

[0058] The area of ​​the wall paving layer 13 and the bottom paving layer 12, and the length of the square tube paving layer 11 should meet the waterproof requirements.

[0059] The processing method of the molded waterproof additional layer can be as follows:

[0060] Because the processed material needs to be shaped, this molded waterproofing additional layer can be produced using a mold. A mold is fabricated based on the dimensions of the area to be waterproofed. The mold includes an inner mold and an outer mold. A baffle is installed at the edge of the outer mold, which fits snugly within the inner mold and fits snugly within the inner mold. The baffle closes the gap between the outer and inner molds. The processed material, which is the roll material of the waterproofing layer in the area to be waterproofed, is attached to the outer mold. Through the extrusion and shaping process between the inner and outer molds, the processed material is formed into a molded additional layer that matches the shape of the outer mold. Both the outer and inner molds are stainless steel.

[0061] The outer and inner molds have the same shape, and the inner mold can be inserted into the outer mold. A gap exists between the two molds to accommodate and extrude the material being processed. Extrusion and external heating of the inner and outer molds can shape the material. Other processes can also be used, such as rolling, hot melting, and banburying. The outer mold's shape and dimensions can match the outer dimensions of the waterproofing area. The resulting additional layer will have the same dimensions as the area to be waterproofed, allowing it to fit snugly over the area, ensuring a tight waterproofing effect. The extended length of the edges of the inner and outer molds should be determined based on the waterproofing construction requirements.

[0062] When the membrane material is asphalt waterproofing membrane, the processing material is attached to the outer mold, including: using base paper, fiber fabric or fiber felt as a carcass, covering and fixing the carcass to the inner surface of the outer mold; adding heated and melted asphalt into the outer mold and evenly applying it to the carcass, impregnating the carcass with asphalt, and then evenly spreading powdered, granular or flaky anti-sticking material on the asphalt-impregnated surface as a covering layer. The inner mold is inserted deeper into the outer mold, the inner mold squeezes the processing material, and the outer surfaces of the inner and outer molds are heated to fuse the carcass, asphalt and covering layer together.

[0063] When the membrane is a synthetic polymer waterproof membrane, the processing material is attached to the outer mold. This includes: a base material of synthetic rubber, synthetic resin, or a mixture of synthetic rubber and synthetic resin, chemical additives and fillers are added to the base material, and then injected into the outer mold. The inner mold is inserted into the outer mold, extruding the base material. The outer surfaces of the inner and outer molds are heated to form the base material. The base material can also be shaped by calendering in the outer mold.

If the upper opening is an inverted cone, the upper cylindrical layer 22 also has an inverted cone shape.

[0068] The formed additional layer is laid just on the round-mouth vertical drain outlet. The corners should be close to the negative and positive corners of the base layer. It should be fully adhered and there should be no hollowing or twisting.
