Description

Technical Field

[0001] The present application belongs to the technical field of building waterproof construction, and in particular relates to a waterproof connection structure. Background Art

[0002] Before the implementation of the "General Specification for Waterproofing of Buildings and Municipal Engineering", a basement pre-laid with a layer of waterproofing membrane can meet the requirements of first-level waterproofing. Among them, when the waterproofing membrane is thrown, because one side of the pre-laid waterproofing membrane sheet faces the brick membrane, it cannot form a bond with the side mold (brick membrane). Usually, the pre-laid waterproofing membrane is mechanically fixed at the 10-20mm overlap edge every 40-60cm, and then the adjacent membrane is laid, and the nail holes are covered by the adjacent membrane to avoid the risk of leakage in the mechanically fixed parts.

[0003] After the implementation of the "General Specification for Waterproofing of Buildings and Municipal Engineering", it is required that when pre-laid waterproofing membranes are used for waterproofing of basements, a waterproof layer needs to be added under the waterproof layer formed by the waterproofing membranes. If the original practice is still adopted, that is, the pre-laid reverse-adhesive waterproofing membranes are used on the basement floor and the waterproofing membranes are constructed by the external anti-sticking method on the side walls, the waterproofing membranes of the floor need to be thrown to the side walls first, and the joints with the waterproofing membranes of the side walls need to be constructed. However, the pre-laid waterproofing membranes at the joints of the floor cannot be bonded to the brick membrane and the side walls. Therefore, it is necessary to fix the waterproofing membranes of the floor to the side walls by mechanical fixing methods such as steel nails, but mechanical fixing will damage the lower waterproof layer, reduce the waterproofing effect of the waterproofing membranes, and increase the risk of leakage at the joints. At the same time, the pre-laid waterproofing membranes reserved at the joints of the floor cannot be directly attached to the side walls, which increases the difficulty of construction. The joints where the waterproofing membranes of the bottom plate overlap the side walls are the most likely places for basement leakage. Therefore, it is necessary to strengthen the waterproofing treatment of the most likely places for leakage. Utility Model Content

[0053] In an embodiment of the present application, the third waterproof membrane is arranged in an interlaced and stacked manner with the first waterproof membrane and the second waterproof membrane, and the fourth waterproof membrane at least covers a portion of the second waterproof membrane, thereby enhancing the connection strength between the first waterproof component and the second waterproof component and forming a complete waterproof layer of three interlaced and stacked layers, thereby improving the waterproof effect and reducing the risk of leakage of the waterproof layer.

[0054] like Figure 4 As shown, in this embodiment, the length of the connecting portion of the first waterproof roll material may also be less than the length of the connecting portion of the second waterproof roll material. It can be understood that the length of the connecting portion of the first waterproof roll material is greater than the length of the connecting portion of the second waterproof roll material, which can form a complete waterproof layer of three mutually staggered layers.

[0055] In some embodiments, Figure 4 As shown, the overlapping lengths of the connecting portion 3a of the first waterproof roll 31 and the third waterproof roll 41, the overlapping lengths of the connecting portion 3a of the second waterproof roll 32 and the third waterproof roll 41, and the overlapping lengths of the connecting portion 3a of the fourth waterproof roll 42 and the second waterproof roll 32 are all ≥150mm, so that the first waterproof component and the second waterproof component are fully staggered and stacked to form a double-layer connection structure. While enhancing the connection strength, a thicker thickness and multiple waterproof connections are formed, thereby enhancing the waterproof effect and service life of the waterproof layer, and preventing the thickness of the waterproof layer from being concentrated at the connection position.

[0056] In some embodiments, Figure 5As shown, the first waterproof assembly 3 includes a first waterproof roll 31 and a second waterproof roll 32; the first waterproof roll 31 covers the bottom surface 100 of the first building component 1, and at least partially extends to the outer surface 200 of the second building component 2, forming a connection portion 3a of the first waterproof roll 31; the second waterproof roll 32 covers the bottom surface of the first waterproof roll 31, covers the connection portion 3a of the first waterproof roll 31 and extends to the outer surface 200 of the second building component 2, forming a connection portion 3a of the second waterproof roll 32; the length of the connection portion 3a of the first waterproof roll 31 is The length is less than the length of the connecting portion 3a of the second waterproof roll 32; the second waterproof assembly 4 includes a third waterproof roll 41 and a fourth waterproof roll 42; the third waterproof roll 41 extends along the outer surface 200 of the second building component 2 from the far end facing away from the first building component toward the proximal end of the second building component, and at least covers a portion of the connecting portion 3a of the second waterproof roll 32, the fourth waterproof roll 42 covers the third waterproof roll 41 and extends in the direction of the second waterproof roll 32 away from the connecting portion 3a, and the fourth waterproof roll 42 is connected to the connecting portion 3a of the second waterproof roll 32.

[0057] In the embodiment of the present application, the length of the connection part of the second waterproof roll is made greater than the length of the connection part of the first waterproof roll, and the connection part of the second waterproof roll is connected to the outer surface of the second building component, that is, the connection part of the second waterproof roll is sandwiched between the second building component and the second waterproof assembly, so that the first waterproof assembly can be fixedly connected to the second building component, and the first waterproof assembly is at least partially covered by the second waterproof assembly to form a complete waterproof layer arranged in staggered layers, so as to improve the waterproof effect. Among them, the connection parts of the first waterproof roll and the second waterproof roll can be independently connected to the outer surface of the second building component to enhance the connection strength between the first waterproof roll and the second building component to varying degrees, and the first waterproof roll is covered and sealed by the second waterproof roll. The third waterproof roll covers the connection part of the second waterproof roll, and the fourth waterproof roll covers the third waterproof roll and covers the connection part connected to the second waterproof roll, which can further form a waterproof layer arranged in staggered layers with the first waterproof assembly, enhance the connection strength and waterproof performance between the second waterproof assembly and the first waterproof assembly, and improve the waterproof effect.

[0058] In some embodiments, Figure 5 As shown, the overlap length of the connecting portion 3a of the third waterproof membrane 41 and the second waterproof membrane 32, and the overlap length of the connecting portion 3a of the fourth waterproof membrane 42 and the second waterproof membrane 32 are both ≥150mm, so that the connecting portion of the first waterproof component and the second waterproof component can be fully staggered and overlapped, which can effectively improve the waterproof effect of the waterproof layer while enhancing the connection strength, and prevent the thickness of the waterproof layer from being concentrated and too thick at the staggered stacking position.

[0059] In an embodiment of the present application, the first waterproof membrane and the second waterproof membrane can be bonded together with the third waterproof membrane and the fourth waterproof membrane by a non-curing adhesive or a double-sided self-adhesive layer to ensure that the waterproof membrane on the outer facade of the second building component can be firmly bonded to form a complete waterproof layer.

[0060] It should be noted that due to Figures 2 to 5 All of them are schematic diagrams of the longitudinal section structure of the waterproof connection structure. Taking the overlap length of the connection part 3a of the third waterproof roll 41 and the first waterproof roll 31 as an example, the overlap length is only shown as the end overlap in the figure. In fact, the connection parts 3a of the third waterproof roll 41 and the first waterproof roll 31 should be fully spread on the outer surface 200 along the width of the outer surface of the second building component 2, and the third waterproof roll 41 covers part of the connection part 3a of the first waterproof roll 31, and the overlapping length in the longitudinal direction H is greater than or equal to 150mm. The same is true for other overlapping lengths, only the overlapping positions are different.

[0061] In some embodiments, the first waterproofing membrane 31 is a back-adhesive polymer self-adhesive film waterproofing membrane, and the second waterproofing membrane 32 is a pressure-sensitive reactive self-adhesive polymer waterproofing membrane. The pressure-sensitive reactive self-adhesive polymer waterproofing membrane can be fully adhered to the concrete cushion 14 under the first building component and the brick membrane 5 used to support the waterproofing membrane, so as to carry out the construction of the back-adhesive polymer self-adhesive waterproofing membrane, so that the first waterproofing membrane and the second waterproofing membrane form a first waterproof assembly that is completely and firmly connected to cover the bottom surface of the first building component and extend to the outer surface of the second building component through the dihedral angle α.

[0062] In some embodiments, Figure 1 As shown, at the connection of the dihedral angle α between the first building component 1 and the second building component 2, a first additional roll material layer 7 is arranged on the outside of the first waterproof component 3. The first additional roll material layer 7 protects the first waterproof component 3 at the dihedral angle from being damaged under pressure or external force.

[0063] In some embodiments, the first additional roll material layer 7 is evenly arranged at the dihedral angle connection, respectively, on the outer side of the first waterproof component of the first building component and the second building component, so as to fully protect the first waterproof components on both sides of the dihedral angle. Exemplarily, the total width of the first additional roll material layer 7 is 500 mm, the width on the side of the supporting brick membrane 5 is ≥ 250 mm, and the width on the side of the concrete cushion layer 14 is ≥ 250 mm.

[0064] In some embodiments, Figure 1As shown, a horizontal seam 9 is formed in the second building component 2 during the construction process, and a second additional roll material layer 10 is arranged between the outer surface 200 of the second building component 2 corresponding to the horizontal seam 9 and the first waterproof roll material 31, so as to seal the horizontal seam along the length direction of the horizontal seam through the second additional roll material layer to prevent external leakage water from entering the room through the horizontal seam.

[0065] It should be noted that the height of the horizontal seam 9 in the second building component 2 can be higher or lower than the position where the first waterproof component and the second waterproof component are interlaced and stacked, and correspondingly, the first waterproof roll 31 can be lower or higher than the second additional roll 10 covering the corresponding position of the horizontal seam 9, and extend to connect to the outer surface of the second building component. Or it can be located at the position where the first waterproof component and the second waterproof component are interlaced and stacked, which is suitable for the horizontal seam 9 to be located at the position where the first waterproof component and the second waterproof component are interlaced and stacked, and the first waterproof roll 31 can cover the second additional roll 10 at the corresponding position of the horizontal seam 9 and extend to connect to the outer surface of the second building component.

[0066] In some embodiments, the second additional roll material layer 10 is evenly arranged along the outer surface 200 of the second building element 2 and perpendicular to the longitudinal direction H of the horizontal seam 9 to ensure that the second additional roll material layer 10 is evenly distributed along the longitudinal direction of the horizontal seam, effectively blocking the horizontal seam position to prevent water from penetrating into the room. Exemplarily, the total width of the second additional roll material layer 10 is ≥500mm, the width along the longitudinal direction H on the upper side of the horizontal seam 9 is ≥250mm, and the width on the lower side of the horizontal seam 9 is ≥250mm.

[0067] In some embodiments, the connection portion 3a of the first waterproof membrane 31 is mechanically fixed to the outer surface 200 of the second building component 2. Exemplarily, the top of the connection portion 3a of the first waterproof membrane 31 connected to the second building component 2 can be further fixedly connected to the second building component 2, i.e., the outer surface of the side wall, using screws or pressure strips or pneumatic nails to enhance the connection strength between the first waterproof membrane and the second building component 2. Exemplarily, at the 1 to 5 cm edge position where the connection portion 3a of the first waterproof membrane 31 is connected to the outer surface of the second building component 2, the first waterproof membrane is mechanically fixed using screws or pressure strips every 40 to 60 cm along the width direction of the first waterproof membrane. The width direction is perpendicular to Figure 1 The longitudinal section (i.e. the direction perpendicular to the viewing plane) is understood that the connecting portion of the first waterproof membrane can also be bonded to the outer surface of the second building element using a non-curing adhesive or a double-sided self-adhesive layer.

[0068] In some embodiments, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the joint 3a of the fourth waterproof membrane 42 and the second waterproof membrane 32 is sealed and connected using a sealant to seal the joint of the waterproof membrane to form a complete water-proof layer and improve the water-proof effect.
