DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] A roof compartment seam leak-proof structure is arranged below the compartment seam 1 to prevent rainwater from leaking into the inner side of the roof through the compartment seam 1. By pre-burying the leak-proof structure below the compartment seam 1, the flatness of the roof structure can be ensured, thereby improving the practicality and aesthetics of the roof.

[0024] The leak-proof structure includes a filling layer 2, an exhaust piece 3 and a leak-proof component 4. The leak-proof component 4 is arranged below the compartment seam 1, the filling layer 2 is filled in the compartment seam 1, and the exhaust piece 3 is connected to the leak-proof component 4. When the compartment seam 1 leaks, the leaked water flows into the leak-proof component 4, and the leak-proof component 4 prevents the leaked water from further penetrating into the roof. Then, the water vapor in the leak-proof component 4 is discharged out of the leak-proof structure through the exhaust piece 3 to prevent the water vapor from accumulating in the leak-proof component 4, thereby further improving the leak-proof performance at the compartment seam 1.

[0025] The filling layer 2 is asphalt. After the construction of the compartment joint 1 is completed, the compartment joint 1 is filled with an asphalt solution to prevent rainwater from accumulating in the compartment joint 1. At the same time, the inner wall of the compartment joint 1 can be bonded to prevent rainwater from leaking into the roof structure through the gap between the compartment joint 1 and the filling layer 2.

[0026] The anti-leakage component 4 includes a support belt 4-3 and a guide member 4-4. The guide member 4-4 is arranged on the support belt 4-3 and is installed through the support belt 4-3. A guide groove 4-1 is formed in the guide member 4-4. The guide groove 4-1 is arranged below the compartment seam 1. The leaked rainwater is collected through the guide groove 4-1 to prevent the leaked rainwater from further leaking. The exhaust member 3 is connected to the guide groove 4-1. The water vapor in the guide groove 4-1 is discharged out of the anti-leakage structure through the exhaust member 3, thereby preventing rainwater from accumulating in the guide member 4-4.

[0027] The support belt 4-3 is cast by concrete mortar. When the support belt 4-3 is cast, a mounting structure for installing the guide member 4-4 is reserved to facilitate the subsequent fixing of the guide member 4-4 on the support belt 4-3. A guide slope 4-2 is provided on the top of the support belt 4-3. The guide slope 4-2 is inclined to facilitate guiding the liquid on the support belt 4-3 to the guide member 4-4.

[0028] A PVC pipe with a diameter of Ø40 is split longitudinally to form a semicircular guide member 4-4. The support belt 4-3 is set slightly higher than the guide member 4-4. A waterproof membrane 8 with a width of 10 cm is pasted between the guide slope 4-2 and the edge of the guide member 4-4 to facilitate the diversion of rainwater into the guide member 4-4.

[0029] The guide groove 4-1 of the guide member 4-4 is filled with a filler 5, and the filler 5 is made of gravel with a diameter less than 1.5 cm, and the height of the filler 5 is 0.4-0.8 cm less than the height of the guide groove 4-1. Through the setting of the filler 5, water vapor can adhere to the surface of the filler 5, thereby increasing the contact area between water and air, facilitating the evaporation of water vapor, and then discharged out of the leak-proof structure through the exhaust member 3.

[0030] The leak-proof structure includes a support member 6, which is M-shaped. A support groove 6-1 is provided in the middle of the support member 6. During the construction of compartment concrete, a flexible insulation strip is placed in the support groove 6-1, so that a compartment seam 1 is formed after the compartment concrete construction is completed.

[0031] In some preferred embodiments, a certain gap is provided between the bottom of the support groove 6-1 and the filler 5. During the construction of the compartmented concrete, part of the concrete is filled under the support groove 6-1. On the one hand, it can prevent the asphalt solution from flowing into the diversion groove 4-1 during the pouring process. On the other hand, the concrete can prevent rainwater from directly flowing into the diversion groove 4-1.

[0032] Connecting feet 6-2 are provided on both sides of the support member 6, and the support member 6 is fixed on the top of the anti-leakage component 4 through the connecting feet 6-2. In this embodiment, the connecting feet 6-2 are parallel to the transition layer, and the connecting feet 6-2 on both sides of the support member 6 face opposite directions, so as to facilitate the placement of the support member 6 on the transition layer.

[0033] In some replaceable embodiments, the connecting foot 6-2 is arc-shaped, which can increase the effective contact area between the connecting foot 6-2 and the transition layer, thereby increasing the stability of the support member 6, and the arc-shaped connecting foot 6-2 can be pressed under the steel cage of the compartment concrete layer 7, so as to fix the position of the support member 6 and ensure that the compartment seam 1 is in a straight state after the construction of the compartment concrete layer 7 is completed.

[0034] The roof includes a cast-in-place floor 9, a transition layer and a compartment concrete layer 7. The transition layer is arranged on the cast-in-place floor 9, the leak-proof structure is arranged above the transition layer, the compartment concrete layer 7 is cast above the leak-proof structure, and compartment seams 1 are formed between adjacent compartment concrete layers 7.

[0035] The transition layer from the cast-in-place floor 9 to the compartment concrete layer 7 includes a waterproof layer 10, an isolation layer 11, an insulation layer 12 and a leveling layer 13 in sequence, which play a role in waterproofing and heat-insulating the cast-in-place floor 9.

[0036] The exhaust component 3 includes an exhaust connecting pipe 3-1 and an exhaust pipe 3-2. The exhaust connecting pipe 3-1 is cross-shaped and is pre-buried in the intersection of the compartment seam 1. The end of the exhaust connecting pipe 3-1 is connected to the end of the guide member 4-4 to facilitate the water vapor in the leak-proof component 4 to flow into the exhaust connecting pipe 3-1. The exhaust pipe 3-2 is connected to the exhaust connecting pipe 3-1 to discharge the water vapor in the leak-proof component 4 to the outside of the roof compartment seam through the exhaust pipe 3-2.

[0037] In some preferred embodiments, a rain shield pipe 3-3 is provided on the top of the exhaust pipe 3-2. Both ends of the rain shield pipe 3-3 are tapered openings. The middle diameter of the rain shield pipe 3-3 is smaller than the opening diameter of the rain shield pipe. When air flows into the middle of the rain shield pipe 3-3 through the opening of the rain shield pipe 3-3, the air flow rate is increased, thereby facilitating the discharge of water vapor in the exhaust component 3. In order to prevent rainwater from entering the rain shield pipe 3-3, shielding covers 3-4 are respectively provided at both ends of the rain shield pipe 3-3.

[0038] A construction method for a roof compartment seam leak-proof structure comprises the following steps: S1, after the construction of the cast-in-place floor 9 is completed, a layer of waterproof coating is applied on it to form a waterproof layer 10, and after the waterproof layer 10 is dried, a thick film isolation layer 11 is laid on it, and after the mortar hardens, an insulation board is laid to form an insulation layer 12, and then a cement mortar leveling layer 8 is constructed on the insulation layer 12. After the mortar of the leveling layer 8 hardens, a 6mX6m grid is popped out with an ink line as the setting position of the leak-proof component 4; S2, fix the mold for casting the support belt on the ink line, and cast the support belt through mortar. During the hardening process of the support belt, split the PVC pipe with a diameter of Ø40 in the longitudinal direction to form a semicircular guide member 4-4, and fix the guide member 4-4 on the support belt; S3, paste a 10cm wide waterproof membrane at the junction of the support belt and the guide piece to prevent rainwater from seeping into the gap between the support belt and the guide piece; S4, placing an exhaust member at the intersection of the guide members, connecting the guide members through the exhaust member, and placing a filler 5 in the guide member, wherein the height of the filler 5 is 0.4-0.8 cm less than the height of the guide groove 4-1; S5, placing a support member on top of the support belt, with the spacing between the support members 6 being 40-60 cm, and placing a flexible insulation strip in the support groove 6-1 of the support member 6, with the width of the flexible insulation strip being substantially the same as the width of the support groove 6-1; S6, placing steel cages on both sides of the support belt, the steel cages are used to increase the strength of the compartment concrete after solidification, and the connecting legs of the support are fixed under the steel cages; S7, compartment concrete construction is performed above the transition layer. After the compartment concrete construction is completed, the flexible insulation strip is removed to form compartment gaps between the compartment concretes, and a filling layer is injected into the compartment gaps.
