[0002] A positive roof is a roof structure in which a waterproof layer is installed above the insulation layer. The waterproof layer is installed on the outside for easy maintenance and does not require the use of hydrophobic insulation materials. The cost is relatively low. Due to the fact that a certain amount of water vapor will be generated between the waterproof layer and the insulation layer when they are in use, multiple exhaust pipes need to be installed on the roof panel when the positive roof is installed.

[0003] Most of the existing exhaust pipes are installed vertically on the roof panels. However, when it rains heavily, rainwater can easily enter the exhaust pipe and then enter between the insulation layer and the waterproof layer through the exhaust pipe. Under the influence of rainwater, the insulation performance of the insulation layer will be weakened. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: when encountering heavy rain, rainwater can easily enter the exhaust pipe, and then enter between the insulation layer and the waterproof layer through the exhaust pipe. Under the influence of rainwater, the insulation layer will weaken the insulation performance, and a positive steel roof PVC waterproof insulation structure is proposed.

[0012] Preferably, a plurality of connecting angle steels are fixedly mounted on the exhaust pipe, and the plurality of connecting angle steels are fixedly mounted on the roof panel by screw fasteners.

[0013] In the utility model, the beneficial effects are:

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3A positive steel roof PVC waterproof and thermal insulation structure, comprising a structural layer 1, a thermal insulation layer 2, a waterproof layer 3 and a roof panel 4, wherein the waterproof layer 3 is made of PVC waterproof coiled material, the thermal insulation layer 2, the waterproof layer 3 and the roof panel 4 are sequentially laid on the structural layer 1, and installation holes are opened on the waterproof layer 3 and the roof panel 4, and the two installation holes overlap each other;

[0021] An exhaust pipe 5 is vertically inserted into the mounting hole, a mounting block 6 is fixedly installed on the upper end of the exhaust pipe 5, a plurality of exhaust holes are opened on the side of the exhaust pipe 5, a rainproof pipe 7 is slidably sleeved on the mounting block 6, a connecting block 8 is fixedly installed on the upper end of the rainproof pipe 7, the connecting block 8 is mounted on the mounting block 6 through an elastic component, a water-absorbing cotton 9 is fixedly installed on the connecting block 8, a moving hole is opened on the connecting block 8, the elastic component includes a support rod 10 vertically fixedly installed on the mounting block 6 and a telescopic spring 11 sleeved on the support rod 10, the support rod 10 is slidably inserted in the moving hole, and the two ends of the telescopic spring 11 are fixedly connected to the mounting block 6 and the connecting block 8 respectively;

[0022] When encountering heavy rain, rain will drip on the absorbent cotton 9, and the weight of the absorbent cotton 9 will become heavier. At this time, the gravity of the absorbent cotton 9 will be greater than the elastic force of the telescopic spring 11, thereby driving the connecting block 8 and the rainproof pipe 7 to move vertically downward along the support rod 10. The telescopic spring 11 is compressed, and the rainproof pipe 7 will be sleeved on the exhaust pipe 5 after moving downward, thereby covering multiple exhaust holes. Under the protection of the rainproof pipe 7, rainwater can be prevented from passing through the exhaust holes into the exhaust pipe 5, reducing the impact of rainwater entering the insulation layer 2 on the roof insulation effect;

[0023] After the rain stops, under the sunlight, the amount of rain on the absorbent cotton 9 will gradually decrease, so that the gravity of the absorbent cotton 9 will become smaller. At this time, under the action of the elastic force of the telescopic spring 11, the connecting block 8 and the rainproof pipe 7 will be driven to move vertically downward, thereby exposing multiple exhaust holes to facilitate the exhaust of the exhaust pipe 5.

[0024] A plurality of support rods 12 are fixedly mounted on the connecting block 8, a conical bucket 13 is fixedly mounted on the upper end of the plurality of support rods 12, and the absorbent cotton 9 is located directly below the conical bucket 13. Under the action of the conical bucket 13, a large amount of rainwater can be collected on the absorbent cotton 9, ensuring that the absorbent cotton 9 can absorb more rainwater in the shortest time.

[0025] A sealing gasket is fixedly installed on the inner wall of the installation hole. The sealing gasket is made of rubber material and can prevent rainwater on the roof panel 4 from penetrating into the installation hole.

[0026] A plurality of L-shaped limit blocks 14 are fixedly mounted on the roof panel 4, and the plurality of limit blocks 14 are arranged in a circle around the exhaust pipe 5. One ends of the plurality of limit blocks 14 are all located below the rainproof pipe 7. When the rainproof pipe 7 moves downward, one end will contact with the plurality of limit blocks 14, thereby limiting the rainproof pipe 7 from moving further downward, ensuring that there is a gap between the lower end of the rainproof pipe 7 and the roof panel 4, thereby facilitating the gas discharged from the exhaust hole to pass through.

[0027] A plurality of connecting angle steels 15 are fixedly mounted on the exhaust pipe 5, and the plurality of connecting angle steels 15 are fixedly mounted on the roof panel 4 by screw fasteners. The exhaust pipe 5 can be mounted on the roof panel 4 by means of the plurality of connecting angle steels 15, which is convenient for connection and maintenance.

[0028] In the utility model, when encountering heavy rain, rainwater will drip onto the absorbent cotton 9, and the weight of the absorbent cotton 9 will become heavier. At this time, the gravity of the absorbent cotton 9 will be greater than the elastic force of the telescopic spring 11, thereby under the action of the elastic component, the connecting block 8 and the rainproof pipe 7 will be driven to move vertically downward. After moving downward, the rainproof pipe 7 will be sleeved on the exhaust pipe 5, thereby covering a plurality of exhaust holes. Under the protection of the rainproof pipe 7, rainwater can be prevented from passing through the exhaust holes into the exhaust pipe 5, thereby reducing the impact of rainwater entering the insulation layer 2 on the thermal insulation effect of the roof.

[0029] In general, in view of the technical problem: when encountering heavy rain, rainwater can easily enter the exhaust pipe 5, and then enter between the thermal insulation layer 2 and the waterproof layer 3 through the exhaust pipe 5. Under the influence of rainwater, the thermal insulation performance of the thermal insulation layer 2 will be weakened; adopt a technical solution: under the cooperation of the connecting block 8 and the elastic component, the rainproof pipe 7 is sleeved on the exhaust pipe 5, so as to cover multiple exhaust holes; because the implementation process of the technical solution is: when encountering heavy rain, rainwater will drip on the absorbent cotton 9, absorbent cotton 9 will absorb water, and the absorbent cotton 9 will absorb water. The weight of the cotton 9 will become heavier. At this time, the gravity of the absorbent cotton 9 will be greater than the elastic force of the telescopic spring 11, so that under the action of the elastic component, the connecting block 8 and the rainproof pipe 7 will be driven to move vertically downward. After moving downward, the rainproof pipe 7 will be sleeved on the exhaust pipe 5, thereby covering a plurality of exhaust holes. Under the protection of the rainproof pipe 7, rainwater can be prevented from passing through the exhaust holes into the exhaust pipe 5; therefore, the technical problem can definitely be solved, and the technical effect achieved is: reducing the impact of rainwater entering the insulation layer 2 on the thermal insulation effect of the roof.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
