Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof membrane technology, specifically to a waterproof membrane with reinforcing ribs to prevent deformation. Background Technology
[0002] In the construction industry, waterproofing membranes refer to thin sheets or rolls of key polymer synthetic materials (commonly such as HDPE, PVC, EVA, TPO, etc.) laid on the base layer of a building structure (such as foundation slabs, basement side walls, roofs, etc.) to isolate groundwater, rainwater, or moisture penetration and form a continuous, sealed waterproof layer. Through physical barriers and its excellent impermeability, it effectively protects the building structure from water erosion and prevents leakage. It is an important component in ensuring the quality and durability of waterproofing projects and often forms a waterproofing system together with structural self-waterproofing.
[0003] Chinese utility model patent CN215106138U discloses a waterproof protective panel for buildings, which includes "a bottom panel, a waterproof layer, an anti-corrosion layer, a structural layer and a top panel laid from bottom to top, wherein the structural layer is provided with reinforcing ribs; and the waterproof layer is also provided with a flow guiding structure"; however, this waterproof panel still uses the traditional arrangement of horizontal and vertical reinforcing bars, which is insufficient in tensile strength under long service time or heavy load, easily leading to deformation of the waterproof panel, and in severe cases, it may break. Utility Model Content
[0004] The purpose of this invention is to provide a waterproof membrane with reinforcing ribs to prevent deformation, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof board with reinforcing ribs to prevent deformation, comprising an upper structure, an intermediate layer at the lower part of the upper structure, and a bottom structure at the lower part of the intermediate layer; the upper structure includes a protective layer, the intermediate layer includes a waterproof layer, a leveling layer at the lower end of the waterproof layer, and a thermal insulation layer at the lower end of the leveling layer; the bottom structure includes a structural layer, wherein several transverse reinforcing bars are fixedly installed in both the upper and lower layers of the structural layer, and several longitudinal reinforcing bars are fixedly installed in both the upper and lower layers of the structural layer; the transverse and longitudinal reinforcing bars are connected by wire binding to form a mesh structure; several connecting reinforcing ribs are welded between the transverse and longitudinal reinforcing bars in the upper and lower layers; several edge reinforcing ribs are welded around the transverse and longitudinal reinforcing bars in the two layers; and the bottom structure is integrally cast concrete.
[0006] The beneficial effects of this utility model are as follows: by setting connecting reinforcing bars between the transverse and longitudinal reinforcing bars of the two layers, the two layers of steel mesh are connected to form a spatial structure. By setting edge reinforcing bars around the perimeter, a triangular stable structure is formed around the perimeter. This can enhance the tensile strength of the waterproof membrane during actual use, thereby preventing deformation of the waterproof membrane, improving the tensile strength of the waterproof membrane, and improving the practicality of the waterproof membrane.
[0007] To accelerate drainage efficiency:
[0008] The protective layer is further configured such that a plurality of water-guiding grooves are provided inside the protective layer, and the water-guiding grooves are divided into two sides and arranged alternately from the middle.
[0009] By adopting the above technical solution, the structure is divided into two parts from the middle, and several sloping water guide channels are set up on each side to guide the water flow to one side of the protective layer for drainage, preventing water from accumulating on one side of the protective layer. The water guide channels on both sides are staggered and do not communicate with each other, which speeds up the drainage efficiency.
[0010] To expedite the drainage of accumulated water:
[0011] Further configuration: Several drainage outlets are provided on both sides of the upper structure, and the positions of the drainage outlets correspond to those of the water guide channel.
[0012] By adopting the above technical solution, each water guide channel is connected to a drain outlet on its side, so that each drain outlet has independent drainage capacity and the drainage efficiency is accelerated.
[0013] To prevent water accumulation from eroding the outer wall of the device:
[0014] A further feature is provided: a drain extension pipe is fixedly installed on the outside of each drain outlet.
[0015] By adopting the above technical solution, a drainage extension pipe is installed on the outside of the cabinet drainage outlet to increase the drainage distance and prevent water from flowing down the outer wall of the device, eroding the outer surface of the device, and reducing the service life of the device.
[0016] To achieve the strength of the strengthening device:
[0017] Further configuration: the interior of the waterproof layer is provided with several waterproof membranes, the interior of the leveling layer is fixedly installed with wire mesh, and the interior of the insulation layer is fixedly installed with polyurethane foam board.
[0018] By adopting the above technical solutions, the waterproof membrane can prevent water from seeping into the lower layer, the wire mesh can enhance the strength of the leveling layer and prevent the leveling mortar from cracking, and the leveling layer can facilitate better subsequent bonding of the waterproof membrane.
[0019] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] Please see Figures 1 to 4 The waterproof slab with reinforcing ribs to prevent deformation includes an upper structure 1, an intermediate layer 2 at the bottom of the upper structure 1, and a bottom structure 3 at the bottom of the intermediate layer 2. The upper structure 1 includes a protective layer 11, the intermediate layer 2 includes a waterproof layer 21, a leveling layer 22 at the bottom end of the waterproof layer 21, and an insulation layer 23 at the bottom end of the leveling layer 22. The bottom structure 3 includes a structural layer 31, with several transverse steel bars 32 and several longitudinal steel bars 33 fixedly installed in both the upper and lower layers of the structural layer 31. The transverse steel bars 32 and the longitudinal steel bars 33 are connected by wire binding to form a mesh structure. Several connecting reinforcing ribs 35 are welded between the transverse steel bars 32 and the longitudinal steel bars 33 in the upper and lower layers. Several edge reinforcing ribs 34 are welded around the two layers of transverse steel bars 32 and the longitudinal steel bars 33. The bottom structure 3 is integrally cast concrete.
[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the protective layer 11 has several water guide channels 12 inside, which are divided into two sides and arranged alternately.
[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, several drainage outlets 13 are provided on both sides of the upper structure 1, and the positions of the drainage outlets 13 correspond to the positions of the water guide channels 12.

[0033] The working process of this reinforced, deformation-resistant waterproof membrane is as follows:
[0034] First, the user binds the horizontal steel bars 32 and the vertical steel bars 33 of the upper and lower layers with wire. Then, the connecting reinforcing bars 35 are welded in the middle, and the edge reinforcing bars 34 are welded around the perimeter, connecting the traditional upper and lower layers of steel mesh into a three-dimensional structure, which enhances the overall tensile strength of the steel bars. Then, concrete is poured in one piece. After that, polyurethane foam board 26 is pasted on the upper part of the bottom structure 3 to form an insulation layer 23. Then, mortar is used for leveling, and wire mesh 25 is placed inside the leveling layer 22 to prevent the mortar from cracking. Then, waterproof membrane 24 is laid on the leveling layer 22 to form the leveling layer 22. Finally, the upper structure 1 is poured on the leveling layer 22, and the water source is guided by the water guide channel 12 inside, and finally discharged through the drainage extension pipe 14.
