Abstract
Description
Technical Field
[0001] This utility model relates to the field of basement roof slab technology, specifically to an installation structure for a waterproof basement roof slab. Background Technology
[0002] The primary function of basement roof waterproofing is to prevent moisture from seeping into the basement, avoiding structural dampness and corrosion, and ensuring the building's durability. Through a multi-layered structure including waterproofing and structural layers, it prevents the penetration of moisture from the soil, rainwater, or groundwater, protecting the equipment, finishes, and structure inside the basement. If the roof is used for planting or vehicular traffic, the waterproofing system must also include drainage and protective layers to ensure timely drainage of accumulated water and prevent damage from plant roots, meeting the needs of different usage scenarios and providing a reliable waterproof barrier for the basement.
[0003] The existing Chinese utility model patent with publication number CN222120491U discloses a waterproof structure for a basement roof slab. This structure includes a second lower support layer, with a first lower support layer positioned above it. The first lower support layer is formed by alternating arrangements of first and second support pieces, which are mirror images of each other and both have an S-shape. This utility model addresses the problem that existing basement roof waterproofing structures primarily rely on a fine aggregate concrete protective layer and a thick cement mortar protective layer for support. This double-layer structure results in a thicker basement roof slab, affecting the interior height. Furthermore, the double-layer support structure fails to block external noise transmission, leading to excessive noise levels inside the basement due to weak sound insulation.
[0004] Currently, the installation structure of the waterproof basement roof slabs in use still has the following problems:
[0005] Because basement roofs are usually covered with green belts, and the bottom of these green belts contains soil, which can not only store water but also slow down water loss, basement roofs are constantly under damp soil, making them highly susceptible to water seepage. Utility Model Content
[0006] The purpose of this utility model is to provide an installation structure for a waterproof basement roof slab to solve the problems mentioned in the background art.
[0007] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:
[0008] This utility model provides an installation structure for a waterproof basement roof slab, including a waterproof roof slab, a grid plate, and an isolation plate. The bottom of the grid plate is in contact with the upper surface of the waterproof roof slab, and a circular hole-shaped isolation plate is installed above the grid plate. The waterproof roof slab has a groove spaced in the middle, and the top of the waterproof roof slab is designed at an angle. A fiber reinforcement layer is installed at the bottom of the waterproof roof slab, and multiple sets of thickened plate layers are installed at intervals in the middle of the fiber reinforcement layer. The thickened plate layers are horizontally located below the groove in the middle of the waterproof roof slab.
[0009] The isolation plate includes an inner groove formed inside a circular hole. A waterproof base plate is installed at the bottom of the inner groove with a thickened layer. The surface of the waterproof base plate is coated with asphalt material with a thickened layer. An arc plate is installed on the inner edge of the inner groove. A partition plate is installed on the top of the arc plate. Both the arc plate and the partition plate have tiny holes on their surfaces.
[0010] Preferably, the upper end of the isolation plate is equipped with a wire mesh plate, and the bottom of the grid plate is arranged with support columns that are connected to the top of the waterproof roof plate, and the top height of the support columns is on the same horizontal line.
[0011] Preferably, an isolation layer is installed at the bottom of the fiber-reinforced layer, and the isolation layer is located above the concrete top slab, the thickness of which is twice that of the isolation layer.
[0012] Preferably, the two sides of the arc plate abut against the inner edge of the inner hole groove, and the positions of the inner hole groove and the square groove in the middle of the grid plate correspond one-to-one.
[0013] Preferably, the grid plate has a plurality of conical grooves arranged in the middle, and the conical grooves are located in the middle of the square grooves inside the grid plate. A second waterproof base plate is installed in the upper middle part of the conical grooves. Guide posts are installed on the edge of the second waterproof base plate, and the bottom of the guide posts is interconnected with the drainer.
[0014] Preferably, the guide post is hollow in the middle, and the surface of the drainer is located at the lower edge of the inner groove.
[0015] Preferably, the support columns are distributed on both sides of the waterproof roof slab, and the middle of the grid plate is directly connected to the middle of the waterproof roof slab.
[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:
[0017] 1. When the basement roof slab is installed, the inner grooves inside the isolation board can retain rainwater from the roots of the plants above. The edges of the inner grooves allow the plant roots to grow horizontally, reducing the chance of plant roots penetrating the waterproof roof slab. In addition, two sets of waterproof base plates are set below the inner grooves, which can improve the waterproof effect above the roof slab. At the same time, the setting of the arc plate and guide column facilitates the drainage of excess water inside the inner grooves from above, reducing the water storage of plant roots, reducing the load on the waterproof roof slab, and improving the safety of the waterproof roof slab structure.
[0018] 2. During the installation of the basement roof slab, a thickened slab layer is installed at intervals on top of the fiber-reinforced layer, located below the groove. The groove in the middle of the waterproof roof slab facilitates the downward flow of water from both sides, reducing the amount of rainwater stored above the waterproof roof slab. The thickened slab layer protects the area below the groove, reducing the chance of rainwater seepage below the groove. At the same time, a thickened concrete slab is set at the bottom of the waterproof roof slab. The concrete slab has good density, which can reduce the chance of steel reinforcement corrosion and prevent aging and cracking. Attached Figure Description

Detailed Implementation
[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0028] Please see Figures 1-4 An installation structure for a waterproof basement roof slab includes a waterproof roof slab 1, a grid slab 3, and an isolation slab 4. The waterproof roof slab 1 has a groove spaced in the middle, and the top of the waterproof roof slab 1 is designed to be slanted. A fiber reinforcement layer 11 is installed at the bottom of the waterproof roof slab 1. Multiple sets of thickened plate layers 12 are installed in the middle of the fiber reinforcement layer 11, and the thickened plate layers 12 are horizontally located below the groove in the middle of the waterproof roof slab 1.
[0029] For details, please refer to the following: Figure 4 As shown, an isolation layer 13 is installed at the bottom of the fiber-reinforced layer 11, and the isolation layer 13 is located above the concrete top slab 14, the thickness of which is twice that of the isolation layer 13.
[0030] The installation structure of the waterproof basement roof slab of this utility model has a sloping top design for the waterproof roof slab 1, which facilitates the flow of rainwater or water droplets stored above, thereby reducing the water storage capacity of the waterproof roof slab 1. At the same time, the thickened plate layer 12 below is located below the groove in the middle of the waterproof roof slab 1, which thickens the bottom of the groove for waterproofing, reducing the possibility of rainwater seeping into the waterproof roof slab 1 when flowing through the groove. In addition, the isolation layer 13 and the thickened concrete roof slab 14 can not only bear more load, but also prevent and make the roof slab structure of the basement firm and tight.
[0031] For details, please refer to the following: Figure 3 As shown, the bottom of the grating plate 3 is in contact with the upper surface of the waterproof top plate 1. Several conical grooves 31 are arranged in the middle of the grating plate 3, and the conical grooves 31 are located in the middle of the square grooves inside the grating plate 3. A second waterproof bottom plate 32 is installed in the upper middle of the conical grooves 31. A guide post 33 is installed on the edge of the second waterproof bottom plate 32, and the bottom of the guide post 33 is interconnected with the drainer 34.
[0032] In this embodiment, the guide post 33 is hollow in the middle, and the surface of the drainer 34 is located at the lower edge of the inner groove 41.
[0033] The installation structure of the waterproof basement roof slab of this utility model has a grid plate 3 that allows water from above to fall directly into the groove in the middle of the waterproof roof slab 1. The conical groove 31 allows the water droplets that condense above to slide down the inclined surface of the cone by gravity, fixing the position of the water droplets and preventing the water droplets from increasing on the surface area of the waterproof roof slab 1. At the same time, it can drain water quickly. The water stored inside the conical groove 31 is discharged to the top of the isolation plate 4 through the hollow guide column 33 and the drainer 34. The isolation plate 4 is located on the shallow surface of the green belt, which is conducive to the rapid evaporation of water from the plant roots.
[0034] For details, please refer to the following: Figure 2 As shown, a circular hole-shaped isolation plate 4 is installed above the grating plate 3. The isolation plate 4 includes an inner hole groove 41 opened inside the circular hole. A waterproof base plate 44 is installed at the bottom of the inner hole groove 41 with a thickened layer. The surface of the waterproof base plate 44 is coated with asphalt material with a thickened layer. An arc plate 42 is installed on the inner edge of the inner hole groove 41. A partition plate 43 is installed on the top of the arc plate 42. Both the arc plate 42 and the partition plate 43 have tiny holes on their surfaces.
[0035] In this embodiment, the two sides of the arc plate 42 and the inner edge of the inner hole groove 41 abut against each other, and the positions of the inner hole groove 41 and the square groove in the middle of the grid plate 3 correspond one-to-one.
[0036] For details, please refer to the following: Figure 1 As shown, a wire mesh plate 5 is installed on the upper end of the isolation plate 4, and support columns 2 connected to the top of the waterproof roof plate 1 are arranged at the bottom of the grid plate 3. The top height of the support columns 2 is on the same horizontal line. The support columns 2 are distributed on both sides of the waterproof roof plate 1, and the middle of the grid plate 3 is directly connected to the middle of the waterproof roof plate 1.
[0037] The installation structure of the waterproof basement roof slab of this utility model includes a wire mesh plate 5 that provides a foundation for plant roots to climb. Plant roots grow along the wire mesh plate 5, which reduces the ability of plant roots to penetrate above the waterproof roof slab 1. At the same time, the edge of the inner groove 41 allows plant roots to grow laterally, which also reduces the ability of plant roots to penetrate above the waterproof roof slab 1, thus improving the waterproof performance of the waterproof roof slab 1 during use. The tiny holes on the surface of the arc plate 42 and the partition plate 43 facilitate the drainage of water inside the inner groove 41, and the holes can reduce soil erosion by the roots. The waterproof bottom plate 44 reinforces the waterproof effect at the bottom of the inner groove 41, providing initial waterproof isolation for plant roots.
[0038] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model 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 utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
