Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of waterproof construction, and specifically relates to a waterproof layer protection structure. Background Art
[0002] Currently in the construction field, the construction sequence of underground waterproofing projects is bottom slab waterproofing layer construction → basement side wall waterproofing layer construction → basement top slab waterproofing layer construction. After the construction of the basement side wall waterproofing layer is completed, it needs to be turned up to the top slab, leaving a gap of not less than 300mm wide. When constructing the top slab waterproofing, the top slab waterproofing layer is overlapped with the gap during laying and turned down to the side wall with a width of not less than 300mm and closed with the side wall waterproofing layer to form an integral waterproof membrane layer.
[0003] After the side wall waterproofing layer is completed, a space for overlapping and turning down needs to be reserved when backfilling, resulting in a 300mm wide space on the top of the side wall that is not backfilled and hidden, and is exposed for a long time. At the same time, the construction of the top slab waterproofing layer requires the removal of the basement side wall frame to replace the space for waterproofing layer construction. During the removal of the frame and backfilling, the waterproofing layer is often not effectively protected, resulting in large-scale damage to the waterproofing layer at the corner, which makes it impossible to effectively close the waterproofing layer during subsequent construction, thus affecting the integrity of the waterproofing layer and reducing the quality of the waterproofing layer. Summary of the invention
[0004] The purpose of this application is to provide a waterproof layer protection structure to achieve waterproof layer protection for the external corners, thereby ensuring the integrity of the waterproof layer and the quality of waterproof construction.
[0005] In order to achieve the above-mentioned object, the present application provides a waterproof layer protection structure on one hand, the waterproof layer protection structure comprising:
[0006] A flexible isolation layer covering the outer side of the waterproof layer turned up along the side wall to the top plate;
[0007] a casting layer, located above the top plate and covering the flexible isolation layer; and
[0008] The protection plate includes a horizontal plate portion extending in the left-right direction and a vertical plate portion extending in the up-down direction, wherein the horizontal plate portion covers the casting layer, and the vertical plate portion covers the flexible isolation layer located outside the side wall.
[0009] In some specific embodiments, the flexible isolation layer may include a non-woven fabric layer; and / or the waterproof layer includes a waterproof roll.
[0010] In some specific embodiments, the protection plate may include a hard plastic plate; and / or, the protection plate may be L-shaped.
[0011] In some specific embodiments, the protection plate may be bonded to the casting layer.
[0012] In some specific embodiments, the casting layer may include a mortar layer.
[0013] In some specific embodiments, the thickness of the casting layer may be greater than or equal to 3 mm.
[0014] In some specific embodiments, a sealing structure may be provided between an edge portion of the waterproof layer on the top plate and the top plate.
[0015] In some specific embodiments, the extended end of the casting layer extends in a direction away from the waterproof layer, and the bottom of the extended end of the casting layer can be connected to the top plate.
[0016] In some specific embodiments, the distance between the edge of the waterproof layer on the top plate and the extended end of the casting layer may be greater than or equal to 40 mm.
[0017] In some specific embodiments, the flexible isolation layer located outside the side wall extends downward and forms a lift-off section extending out of the lower end of the protection plate; and / or,
[0018] The protection plate further includes an inclined plate portion connected to the transverse plate portion, and the inclined plate portion extends downward in a direction away from the waterproof layer.
[0019] Through the above technical scheme, after the construction of the side wall waterproof layer is completed, a flexible isolation layer is laid on the waterproof layer at the external corner to perform the first soft protective film protection, and then a casting layer is arranged above the flexible isolation layer to form a second rigid protective layer for the waterproof layer above the top plate, and then a protective plate is covered on the casting layer and on the outside of the flexible isolation layer on the side wall, thereby forming a complete protective structure that can resist the squeezing of heavy objects and the trampling of pedestrians, protect the waterproof layer from damage, and protect the external corner from damage, thereby ensuring the integrity of the waterproof layer and the quality of the waterproof construction.

[0031] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.
[0032] In current construction, awareness of protective measures for external corners is very weak. In the prior art, wooden boards are usually temporarily placed or a layer of colored strips are laid at the external corners. During cross-operation, the wooden boards or colored strips are easily displaced and damaged, and the waterproof layer at the external corners cannot be effectively protected, which eventually causes damage to the waterproof layer, which may even be beyond repair when the damage is severe.
[0033] In view of this, if Figure 1 and Figure 2 As shown, the utility model provides a novel waterproof layer protection structure, which includes a flexible isolation layer 21, a casting layer 22 and a protection plate 23. The flexible isolation layer 21 covers the outer side of the waterproof layer 13 turned up along the side wall 11 to the top plate 12, the casting layer 22 is located above the top plate 12 and covers the flexible isolation layer 21, and the protection plate 23 includes a horizontal plate portion 231 extending in the left-right direction and a vertical plate portion 232 extending in the up-down direction, the horizontal plate portion 231 covers the casting layer 22, and the vertical plate portion 232 covers the flexible isolation layer 21 located on the outer side of the side wall 11.
[0034] In this way, after the waterproof layer is constructed at the external corner, a flexible isolation layer 21 is laid on the outer side of the waterproof layer 13 extending horizontally and the waterproof layer 13 extending vertically at the external corner, so as to form the first soft protective film for the waterproof layer 13 at the external corner. A casting layer is cast on the flexible isolation layer 21 extending horizontally at the external corner to form a rigid protective layer. Then, a protective plate 23 is added on this basis, and the horizontal plate portion 231 of the protective plate 23 covers the casting layer 22, and the vertical plate portion 232 covers the flexible isolation layer 21 located on the external side wall 11, so as to form a fixed and complete protective measure. The waterproof layer protection structure is used as a buffer layer for the top plate concrete, which can prevent friction damage to the waterproof layer 13 caused by people and various facilities during cross-operation, thereby improving the reliability of the waterproof layer 13.
[0035] Specifically, Figure 1 As shown, on the positive corner of the basement, the waterproof layer 13 includes a waterproof roll, which extends upward along the side wall of the basement and reserves a sling, and the sling of the waterproof roll is turned up to the top plate 12 of the basement, that is, the waterproof roll includes a side wall roll portion and a sling laid on the outside of the side wall 11. The flexible isolation layer 21 is made of flexible material and includes a transverse isolation portion extending in the transverse direction and a vertical isolation portion extending in the vertical direction. The transverse isolation portion of the flexible isolation layer 21 covers the sling of the waterproof roll, and the vertical isolation portion of the flexible isolation layer 21 covers the outside of the side wall roll portion of the waterproof roll, thereby forming a flexible protective film for the waterproof layer 13. The casting layer 22 is formed by casting, and the casting layer 22 is cast on the transverse isolation portion of the flexible isolation layer 21, so as to protect the waterproof layer 13 and prevent large and heavy objects and sharp objects from damaging the waterproof layer 13 during cross-operation. The horizontal plate portion 231 of the protection plate 23 covers the casting layer 22, thereby further strengthening the protection of the waterproof membrane from being swayed. The vertical plate portion 232 of the protection plate 23 covers the flexible isolation layer 21 located on the outside of the side wall 11, which can protect the side wall membrane portion of the waterproof membrane and avoid damage to the waterproof layer 13 when the external frame is removed and backfilled on the side wall.
[0036] Optionally, the waterproof layer 13 may be a single-layer structure or a multi-layer structure. When the waterproof layer 13 is a multi-layer structure, in addition to the waterproof coiled material, it may also include a waterproof coating layer and other structures.
[0037] In some specific embodiments, the flexible isolation layer 21 may include a flexible material layer such as a non-woven fabric layer or a woven fabric layer, thereby achieving the purpose of flexible isolation.
[0038] In some specific embodiments, Figure 1As shown, the protection plate 23 is L-shaped and is inverted on the outer corner, so that it can be attached to the vertical isolation part of the casting layer 22 and the flexible isolation layer 21 for protection. The plate surface of the protection plate 23 can be a smooth plate surface, so that it has better adhesion with the flexible isolation layer 21, and can also reduce friction with the upper object to reduce lateral force.
[0039] Optionally, the protection plate 23 may be a solid plate or a hollow plate with a buffer compartment, etc. The protection plate 23 is made of a hard material to form a rigid protection layer for the waterproof layer 13. The protection plate 23 may be a single-layer plate structure or a multi-layer composite plate body.
[0040] Optionally, the protection plate 23 may be a prefabricated part and include a hard plastic plate, which has corrosion resistance and can be reused, which is more energy-saving and environmentally friendly for project construction. Alternatively, the protection plate 23 may also be a steel plate or a wooden plate.
[0041] In some specific embodiments, the protection plate 23 is bonded to the casting layer 22, so that the protection plate 23 can be fixed on the casting layer 22 to prevent the protection plate 23 from slipping and shifting. Figure 1 As shown, the protection plate 23 and the casting layer 22 can be bonded by a plurality of self-adhesive strips 25. Alternatively, the protection plate 23 and the casting layer 22 can be bonded by applying an adhesive layer.
[0042] Optionally, since both the casting layer 22 and the protection plate 23 have a certain thickness, when the casting layer 22 and the protection plate 23 are laid on the flexible isolation layer 21, they will be higher than the top plate 12 by a certain distance, that is, a small step is formed. Construction personnel or equipment are likely to kick or hit the small step when passing by, which not only poses certain safety hazards, but also causes a certain displacement of the waterproof layer protection structure, which is not conducive to the protection of the waterproof layer 13. To this end, the protection plate 23 of the present application may also include an inclined plate portion (not shown in the figure) connected to the horizontal plate portion 231, which extends downward in a direction away from the waterproof layer 13, so that an inclined transition structure can be formed between the waterproof layer protection structure and the top plate 12, so as to reduce the impact on the passage of construction personnel and equipment, and make the waterproof layer protection structure safer and more reliable. In addition, the inclined plate portion of the protection plate 23 can also enhance the fixing effect between the protection plate 23 and the casting layer 22, and further prevent the protection plate 23 from sliding and displacing.
[0043] In some specific embodiments, the casting layer 22 may include a mortar layer; or, the casting layer 22 may include a concrete layer; or, the casting layer 22 may also include a composite casting layer consisting of a mortar layer and a concrete layer, etc.
[0044] In some specific implementations, the thickness of the casting layer 22 is greater than or equal to 3 mm; preferably, the thickness of the casting layer 22 is greater than or equal to 5 mm, so that the casting layer 22 can be guaranteed to have sufficient structural strength.
[0045] In some specific embodiments, a sealing structure 24 is provided between the edge of the waterproof layer 13 on the top plate 12 and the top plate 12, so as to prevent sand or other small debris from entering the gap between the waterproof layer 13 and the top plate 12. Figure 1 As shown, the sealing structure 24 can be formed by filling the node sealing paste, or the sealing structure 24 can also be formed by brushing an adhesive layer, etc.
[0046] In some specific embodiments, the extended end of the casting layer 22 extends in a direction away from the waterproof layer 13, and the bottom of the extended end of the casting layer 22 is connected to the top plate 12. In this way, the extended end of the casting layer 22 can be connected and closed with the top plate 12, which can prevent sand or other small debris from entering the gap between the casting layer 22 and the top plate 12, and can also fix the casting layer 22, making the waterproof layer protection structure safer and more reliable.
[0047] In some specific embodiments, the distance between the edge of the waterproof layer 13 on the top plate 12 and the end surface of the extended end of the casting layer 22 may be greater than or equal to 40 mm. Preferably, the distance between the edge of the waterproof layer 13 on the top plate 12 and the end surface of the extended end of the casting layer 22 may be greater than or equal to 50 mm. In this way, the fixation of the casting layer 22 is better.
[0048] In some specific embodiments, the flexible isolation layer 21 located outside the side wall 11 extends downward and forms an open section extending out from the lower end of the protection plate 23. Since the open section extends downward from the lower end of the protection plate 23, when backfilling, the backfill material can be prevented from entering the gap between the side wall lower protection structure 14 and the side wall 11. In addition, during subsequent construction, it is only necessary to find this open section from the side wall and open it by "reverse method" to disassemble the waterproof layer protection structure, making the construction more convenient.
[0049] It should be noted that in the present application, unless otherwise specified, directional words such as "inside" refer to a position relatively close to the basement room, and "outside" refers to a position relatively far from the basement room.
[0050] The following is an example of the construction steps of the waterproof layer protection structure of the utility model:
[0051] 1. Perform sealing treatment on the joints of the waterproof layer 13;
[0052] 2. Lay the flexible isolation layer 21, ensuring that the flexible isolation layer 21 is flat and completely covers the waterproof layer 13;
[0053] 3. Pour a 5mm thick pouring layer 22 on the upper area of the waterproof layer 13. The pouring layer 22 expands 50mm outward to connect and close with the top plate 12, and maintains it to prevent cracking;
[0054] 4. After the pouring layer 22 hardens, affix the double-sided self-adhesive tape 25, lay the protection plate 23 (prefabricated part) and affix it firmly.
[0055] To sum up, the waterproof layer protection structure of the utility model adopts a casting layer and a protection plate as a protective layer of the waterproof layer, which can avoid friction damage to the waterproof layer caused by people and various facilities during cross-operation. On the other hand, it can be used as a buffer layer for the top plate concrete to improve the reliability of the waterproof layer. At the same time, since the protection plate made of hard plastic material has the characteristics of corrosion resistance, it can be reused, which is more energy-saving and environmentally friendly for project construction.
