Description

Technical Field

[0001] The utility model relates to the technical field of roof structures, and more specifically, particularly to a roof anti-leakage structure for building construction projects. Background Art

[0002] In building construction, roof waterproofing is a very important construction link, and the quality of roof construction can directly affect the use function of the building. In the construction of roof waterproofing and thermal insulation, it is necessary to strengthen the construction quality control and strengthen the house leakage treatment, so as to ensure the use function of the building and extend the service life of the building. However, the building insulation layer does not have the effect of waterproofing. However, waterproofing and thermal insulation have always been "inseparable", especially in roof construction. How to do a good job of roof waterproofing and thermal insulation is related to the protection function of the overall structure of the house and can play a good role in protecting its service life.

[0003] In the prior art, from the perspective of roof structure, the waterproof layer is made on the thermal insulation layer, which is called the straight laying method. The waterproof layer is made on the thermal insulation layer to take into account the water absorption problem of the thermal insulation material. Once the waterproof layer is damaged, the thermal insulation material absorbs moisture and causes water seepage, thereby reducing the thermal insulation performance of the thermal insulation material and reducing the life of the thermal insulation material. If there is more rainfall in the rainy season, the damage is more serious. How to protect the thermal insulation layer after the waterproof layer is damaged is a technical problem that needs to be solved urgently. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a roof anti-leakage structure for building construction projects, which can still have a hydrophobic effect after the waterproof layer is damaged, so that the thermal insulation layer is not damaged.

[0005] The roof anti-leakage structure for building construction projects includes a thermal insulation layer, a slope and leveling layer, a waterproof layer and a surface layer arranged in sequence from top to bottom, and also includes a hydrophobic layer arranged between the thermal insulation layer and the slope and leveling layer, the hydrophobic layer is used to isolate the water that penetrates after the waterproof layer is damaged and discharge the water through a rainwater pipe; the hydrophobic layer includes a water guide plate, a support block and a cross plate arranged in sequence from bottom to top, the water guide plate is arranged above the thermal insulation layer, a plurality of water guide grooves connected to the upper end surface thereof are opened at equal intervals in the water guide plate, the support blocks are arranged on both sides of the water guide grooves, the cross plate is arranged on the upper end surface of the support block, the water guide grooves are connected to the water inlet end of the elbow, and the water outlet end of the elbow is located above the water inlet end of the rainwater pipe.

[0006] Furthermore, the water guide plate and the support block, the support block and the transverse plate, and the two transverse plates are bonded together by adhesive.

[0007] Furthermore, the slope of the water guide trough is consistent with the slope of the slope and leveling layer, and the lowest point is located close to the rainwater pipe.

[0008] Furthermore, a slope and leveling layer is arranged on the transverse plate, the waterproof layer is laid on the slope and leveling layer, and the end of the waterproof layer is sealed.

[0009] Furthermore, the cross section of the support block is an isosceles trapezoid.

[0010] Furthermore, the transverse plate is a stainless steel plate with holes, the support block is hollow inside and is made of stainless steel, and the water guide plate is a stainless steel plate.

[0011] Furthermore, the hydrophobic layer also includes a first filter plate arranged on the water guide groove, a second filter plate is arranged between two adjacent support blocks, and activated carbon is filled between two adjacent support blocks.

[0012] Furthermore, a baffle is connected between two adjacent support blocks and close to one side of the parapet.

[0013] Furthermore, the parapet is provided with a first opening and a second opening, the water inlet end of the elbow is respectively connected to the first opening and the second opening, and the water inlet end of the elbow located in the first opening passes through the water guide groove near the first opening.

[0014] Furthermore, the slope and leveling layer is constructed by making arc corners only at the corners.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the utility model, when the waterproof layer is damaged, moisture penetrates from the damaged part through the slope and leveling layer and enters into the hydrophobic layer. After entering into the hydrophobic layer, it first enters into between two adjacent support blocks through the pores on the horizontal plate. Since the support blocks are isosceles trapezoids and the inclined surface is close to the water guide groove, the moisture enters into the water guide groove along the inclined surface. The water in the water guide groove flows to the connection with the elbow and is finally discharged from the rainwater pipe, thereby isolating the moisture and preventing the moisture from contacting with the thermal insulation layer and damaging the thermal insulation layer.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment:

[0027] like Figure 1-5 As shown, the roof anti-leakage structure for building construction projects includes an insulation layer 1, a slope and leveling layer 2, a waterproof layer 4 and a surface layer 5 arranged in sequence from bottom to top, wherein a hydrophobic layer 3 is arranged between the insulation layer 1 and the slope and leveling layer 2, and the waterproof layer 4 is a waterproof membrane. When the waterproof membrane is damaged, the hydrophobic layer 3 can isolate moisture to prevent water from corroding the insulation layer 1, and can evacuate water to the rainwater pipe 6 and then discharge it.

[0028] like Figure 1-5As shown, the hydrophobic layer 3 includes a water guide plate 31, a support block 32 and a cross plate 33 arranged in sequence from bottom to top, the water guide plate 31 is arranged above the thermal insulation layer 1 and connected to the thermal insulation layer 1 by an adhesive, a plurality of water guide grooves 311 connected to the upper end surface of the water guide plate 31 are evenly spaced on the water guide plate 31, a plurality of support blocks 32 are evenly spaced on the upper end surface of the water guide plate 31, the support blocks 32 are arranged on both sides of the water guide groove 311 and there is a water guide groove 311 between two adjacent support blocks 32, the cross section of the support block 32 is an isosceles trapezoid and the lowest point of the inclined surface is located above the water guide groove 311, and the cross plate 33 is arranged on the upper end of each support block 32 The horizontal plate 33 is a stainless steel plate with holes, the supporting block 32 is hollow inside and is made of stainless steel, the water guide plate 31 is a stainless steel plate, the water guide plate 31 and the supporting block 32, the supporting block 32 and the horizontal plate 33, and the two horizontal plates 33 are all bonded by adhesive; the water guide groove 311 is connected to the water inlet end of the elbow 7, and the water outlet end of the elbow 7 is located above the water inlet end of the rainwater pipe 6. A slope and leveling layer 2 is arranged on the horizontal plate 33, the slope of the water guide groove 311 is consistent with the slope of the slope and leveling layer 2, and the lowest point is located near the rainwater pipe 6, and a waterproof layer 4 is laid on the slope and leveling layer 2, and the end of the waterproof layer 4 is sealed with sealing paste. When the waterproof layer 4 is damaged, moisture penetrates from the damaged part through the slope and leveling layer 2 and enters the hydrophobic layer 3. After entering the hydrophobic layer 3, it first enters between two adjacent support blocks 32 through the pores on the cross plate 33. Since the support block 32 is an isosceles trapezoid and the inclined surface is close to the water guide groove 311, the moisture enters the water guide groove 311 along the inclined surface. The water in the water guide groove 311 flows to the connection with the elbow 7 and is finally discharged from the rainwater pipe 6, isolating the moisture and preventing the moisture from contacting the insulation layer 1 and damaging the insulation layer 1.

[0029] like Figure 1-5 As shown, the hydrophobic layer 3 also includes a first filter plate 34 arranged on the water guide groove 311, the first filter plate 34 is a perforated stainless steel plate and is welded on the water guide groove 311, and a second filter plate 35 is arranged between two adjacent support blocks 32, the second filter plate 35 is a perforated stainless steel plate and is welded between the two support blocks 32. In this embodiment, two second filter plates 35 are arranged between two adjacent support blocks 32, and activated carbon 36 is filled between two adjacent support blocks 32. By setting the activated carbon 36, a small amount of moisture that enters between the two support blocks 32 after the waterproof layer 4 is damaged can be adsorbed, the moisture can be preliminarily isolated, and the hydrophobic pressure of the water guide groove 311 can be relieved. In this embodiment, the activated carbon 36 is a columnar activated carbon with a diameter of 10 mm, and the hole diameters of the first filter plate 34 and the second filter plate 35 are less than 10 mm.

[0030] like Figure 4 , Figure 5As shown, a baffle 37 is connected between two adjacent support blocks 32 near the parapet 8. The baffle 37 is attached to the parapet 8 and the upper end surface is flush with the upper end surface of the support block 32. The baffle 37 can isolate the water between the two adjacent support blocks 32 to prevent it from eroding the parapet 8.

[0031] like Figure 1-5 As shown, the parapet 8 is provided with a first opening 81 and a second opening 82, which need to be reserved in advance during pouring, and the two water inlet ends of the elbow 7 are respectively connected to the first opening 81 and the second opening 82, and the end of the elbow 7 connected to the second opening 82 passes through the waterproof layer 4 and the surface layer 5. It is necessary to pay attention to leaving openings in the waterproof layer 4 and the surface layer 5 during construction.

[0032] like Figure 1-6 As shown, the opening size of the water guide groove 311 is the same as the first opening 81, and the water inlet end of the elbow 7 located in the first opening 81 penetrates into the water guide groove 311 near the first opening 81, so that the water in the hydrophobic layer 3 can be discharged, and the two adjacent water guide grooves 311 are connected, and a slope with a slope is set at the connecting point, and the slope of the connecting point is the same as the design slope of the roof drainage, and the slope direction is also the same, so that the water in the water guide plate 31 can be discharged from the water guide groove 311 connected to the elbow 7.

[0033] like Figure 1-5 As shown, when the slope and leveling layer 2 is constructed to the corners, it is made into an arc angle to facilitate the laying of the waterproof layer 4.

[0034] like Figure 1-5 As shown, in this embodiment, the insulation layer 1 is a 120mm thick cement polystyrene insulation board, the slope and leveling layer 2 uses 1:6 cement slag with a lowest thickness of 30mm and a slope of 2%, vibrated and compacted, the surface is smoothed, and leveled with 20mm thick 1:2.5 cement mortar, the surface layer 5 is 70mm thick fine stone concrete, the water guide plate 31 is a 50mm thick stainless steel plate, the support block 32 is 50mm high, and the cross plate 33 is 10mm thick. Before laying the insulation layer 1 on the floor slab 9, it is necessary to level it, level the uneven and cracked areas first, and block the walls at the leaking areas.

[0035] The working principle of the roof anti-leakage structure for building construction projects in this embodiment is: when the waterproof layer 4 is damaged, moisture penetrates from the damaged part through the slope and leveling layer 2 and enters the hydrophobic layer 3. After entering the hydrophobic layer 3, it first enters between the two adjacent support blocks 32 through the pores on the cross plate 33. Since the support block 32 is an isosceles trapezoid and the inclined surface is close to the water guide groove 311, the moisture enters the water guide groove 311 along the inclined surface. Since the two adjacent water guide grooves 311 are connected, and a sloped inclined surface is set at the connecting part, and the slope of the connecting part is the same as the designed slope of the roof drainage, and the slope direction is also the same, the water in the water guide plate 31 can be discharged from the water guide groove 311 connected to the elbow 7, and finally discharged from the rainwater pipe 6, isolating the moisture, preventing the moisture from contacting the thermal insulation layer 1 and damaging the thermal insulation layer 1, so that the present structure can still have a hydrophobic effect after the waterproof layer is damaged, so that the thermal insulation layer 1 is not damaged.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
