Technical Field

[0001] The utility model belongs to the technical field of roof waterproofing, and particularly relates to a combined roof waterproof layer structure. Background Technique

[0002] Combined roof waterproofing refers to transferring a large amount of on-site operation work in traditional construction methods to the factory. Components and fittings for roof waterproofing are processed and manufactured in the factory, transported to the construction site, and assembled and installed on-site through reliable connection methods to form a roof waterproofing structure.

[0003] Currently, for the roof waterproofing structure, the processed waterproof base plates are laid on the roof as required, and the laid waterproof base plates are fixed through fixing parts, and the gaps at the fixed parts are sealed to prevent the accumulated water on the surface of the waterproof layer from seeping and leaking. However, when the waterproof base plates on the roof are accumulated with water on the surface for a long time during rainy weather, the accumulated water on the surface of the waterproof layer is prone to erode the waterproof layer on the surface of the waterproof base plate, resulting in the accumulated water on the surface of the waterproof base plate seeping into the building structure of the roof and affecting the waterproof performance of the roof. Content of the Utility Model

[0004] The purpose of the utility model is to provide a combined roof waterproof layer structure to solve the problems raised in the above background technique.

[0006] A waterproof base plate, connecting plates are respectively connected to both sides of the waterproof base plate, and adjacent two groups of connecting plates are fixed through fixing parts. By placing the positioning plate of the fixing part at the connection of two waterproof base plates, two bolts arranged on the surface of the positioning plate penetrate through the connecting plates and are screwed with nuts in the fixing plate.

[0007] A hydrophobic component, the hydrophobic component is arranged in the waterproof base plate. Through the first waterproof layer of the hydrophobic component, the water seeping into the waterproof base plate is drained into the drainage groove, so that the drain pipe connected to the bottom of the drainage groove discharges the water out of the waterproof base plate.

[0008] Preferably, the waterproof base plate comprises a concrete protective layer, the first waterproof layer is arranged at the bottom of the concrete protective layer and is inclined, a plurality of support columns are connected between the first waterproof layer and the concrete protective layer, and second waterproof layers are symmetrically arranged on both sides of the concrete protective layer.

[0009] Preferably, the drainage groove is arranged in one of the second waterproof layers, and a heat preservation layer is arranged at the bottom of the second waterproof layer.

[0012] Preferably, the nut is arranged in the fixing plate, and the bolt passes through the mounting hole in the connecting plate and is screwed with the nut.

[0013] Preferably, a sealing gasket is provided at the connection between the positioning plate, the fixing plate and the connecting plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] When the surface of the roof waterproof substrate is accumulated with water for a long time and seeps into the concrete protective layer, the first waterproof layer at the bottom of the concrete protective layer can timely drain the infiltrated water into the drainage groove and discharge it through the drain pipe, thereby greatly reducing the damage of the accumulated water to the waterproof substrate, significantly improving the waterproof performance of the roof, reducing the damage to the roof building structure caused by leakage, and prolonging the service life of the roof.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides a combined roof waterproof layer structure as Figures 1-3 shown, including:

[0023] A waterproof base plate 1, with connecting plates 2 respectively connected to both sides of the waterproof base plate 1. Adjacent two groups of connecting plates 2 are fixed by fixing parts. By placing the positioning plate 3 of the fixing part at the connection of two groups of waterproof base plates 1, two bolts 4 arranged on the surface of the positioning plate 3 penetrate through the connecting plate 2 and are screwed with nuts 6 in the fixing plate 5;

[0024] A hydrophobic component, which is arranged in the waterproof base plate 1. Through the first waterproof layer 7 of the hydrophobic component, the water seeping into the waterproof base plate 1 is drained into the drainage groove 8, so that the drain pipe 9 connected to the bottom of the drainage groove 8 discharges the water out of the waterproof base plate 1.

[0025] The waterproof base plate 1 includes a concrete protection layer 10. The first waterproof layer 7 is arranged at the bottom of the concrete protection layer 10 and the first waterproof layer 7 is arranged in an inclined shape. A number of support columns 17 are connected between the first waterproof layer 7 and the concrete protection layer 10. Second waterproof layers 11 are symmetrically arranged on both sides of the concrete protection layer 10. Both the first waterproof layer 7 and the second waterproof layer 11 are ethylene propylene diene monomer (EPDM) waterproof coiled materials, which have good waterproof performance and can prevent rainwater from penetrating. And the support columns 17 between the first waterproof layer 7 and the concrete protection layer 10 play a role of support and reinforcement between the first waterproof layer 7 and the concrete protection layer 10, preventing the waterproof base plate 1 from deforming or collapsing due to its own weight or external force.

[0026] The drainage groove 8 is arranged in one of the second waterproof layers 11. A heat preservation layer 12 is arranged at the bottom of the second waterproof layer 11, and a wear-resistant layer 13 is arranged at the bottom of the heat preservation layer 12. The heat preservation layer 12 is a rock wool board. Through the heat preservation layer 12, the heat transfer between the roof and the interior can be reduced, improving the heat preservation performance of the roof. And the wear-resistant layer 13 is a rubber board, which is used to protect the waterproof layer and the heat preservation layer 12 above it from being worn by external factors.

[0027] Positioning blocks 14 are arranged on the surfaces of the connecting plates 2, and positioning grooves 15 are arranged on the surfaces of the positioning plate 3 and the fixing plate 5. The positioning blocks 14 are inserted into the positioning grooves 15.

[0028] The nut 6 is provided inside the fixing plate 5. The bolt 4 passes through the mounting hole in the connecting plate 2 and is screwed to the nut 6. Both the nut 6 and the bolt 4 are made of stainless steel to avoid rusting when getting wet. And during subsequent regular inspections, the connection part of the nut 6 and the bolt 4 can be regularly inspected to prevent loosening.

[0029] Sealing gaskets 16 are provided at the connection parts of the positioning plate 3 and the fixing plate 5 with the connecting plate 2. The sealing gaskets 16 can enhance the sealing performance of the connection parts and prevent water from entering.

[0030] For this combined roof waterproof layer structure, by correctly laying two groups of waterproof substrates 1 on the roof, placing the positioning plate 3 and the fixing plate 5 on the top and bottom of the connecting plate 2 of the two groups of waterproof substrates 1, the positioning blocks 14 on the surface of the connecting plate 2 are inserted into the positioning grooves 15 on the surfaces of the positioning plate 3 and the fixing plate 5 for correct positioning, which is convenient for subsequent installation. Then, two groups of bolts 4 on the surface of the positioning plate 3 pass through the mounting holes on the connecting plate 2 and are screwed to the nuts 6 inside the fixing plate 5, thus completing the installation and fixation of the two groups of waterproof substrates 1. And sealing gaskets 16 are provided at the connection parts of the positioning plate 3 and the fixing plate 5 with the connecting plate 2, which can enhance the sealing performance of the connection parts and prevent water from entering. Also, the second waterproof layers 11 symmetrically arranged on both sides of the waterproof substrate 1 can be connected or overlapped at the connection part to cover the connection part. When rainwater contacts the connection part, it will first encounter the obstruction of the second waterproof layer 11, increasing the difficulty of rainwater penetration. Sealant strips can also be pasted or embedded along the gap at the connection part of the two groups of waterproof substrates 1 to ensure that the sealant strips are closely fitted with the waterproof substrates 1 to form a continuous sealing band to block rainwater penetration and further enhance the waterproof effect. And at the connection part between the waterproof substrate 1 and the wall at the corner, materials such as sealant or waterproof tape can also be used to fill and seal the gap at the corner to further enhance the waterproof effect.

[0031] The waterproof substrate 1 includes structures such as a concrete protection layer 10, a first waterproof layer 7, and a second waterproof layer 11. During normal use, the first waterproof layer 7 and the second waterproof layer 11 jointly function to prevent external rainwater from penetrating into the roof building structure. And when it rains and there is water accumulation on the roof, if a small amount of rainwater seeps through the surface of the concrete protection layer 10 into the first waterproof layer 7 of the waterproof substrate 1, due to the inclined setting of the first waterproof layer 7, the infiltrated water will be drained into the drainage groove 8. A drain pipe 9 is connected to the bottom of the drainage groove 8. The drain pipe 9 can be connected to an external diversion pipe when laying the waterproof substrate 1, so that the water in the drain pipe 9 can be discharged outside the waterproof substrate 1 through the diversion pipe, thus avoiding long-term accumulation of water in the waterproof substrate 1 from eroding the waterproof layer and effectively preventing water from penetrating into the building structure of the roof.

[0032] The thermal insulation layer 12 can play a role in heat insulation, reducing the heat exchange between indoors and outdoors, improving the thermal insulation performance of the roof. The wear-resistant layer 13 at the bottom of the thermal insulation layer 12 can resist the wear of the waterproof layer structure caused by external factors and extend the service life of the entire waterproof layer structure.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
