Description

Technical Field

[0001] The invention relates to the field of construction, in particular to a novel assembled building roof structure. Background Art

[0002] The use of prefabricated panels to build houses is a common construction method and can be widely used in the fields of oil and gas industry, shipbuilding industry, power plants, chemical plants, water treatment plants, etc. to manufacture partitions, containers, storage tanks and other equipment.

[0003] This versatility makes precast panels widely used in various fields. Compared with comprehensive cast roofs, they have the advantages of convenient and fast construction and low price.

[0004] However, due to the natural defects of concrete structure, it is easy to crack and leak after a long period of use, and water vapor is easily accumulated in the precast panels of the floor. If the water vapor cannot be discharged in time, it will easily damage the structure of the precast panels, turning the concrete into powder and slag, and easily causing the steel layer to rust. The traditional precast panel structure cannot discharge the invading water in time.

[0005] In view of this, the present invention proposes a novel assembled building roof structure to solve the above technical problems. Summary of the invention

[0006] In order to solve the deficiencies of the prior art, the present invention provides a novel assembled building roof structure, which can effectively discharge the water that has penetrated therein.

[0007] The present invention provides a novel assembled building roof structure, comprising a supporting prefabricated plate, wherein the supporting prefabricated plate comprises a main supporting layer, a first waterproof layer is applied to the upper end of the main supporting layer, and a multi-layer grid-shaped steel bar structure is fixedly arranged in the main supporting layer; The lower end of the main support layer is fixedly connected with a thermal insulation layer by bolts, and the lower end of the thermal insulation layer is coated with a second waterproof layer. A ventilation device is arranged in the thermal insulation layer, and the ventilation device comprises an air inlet pipe, an air outlet pipe and a water vapor release pipe. The air inlet pipe and the air outlet pipe are respectively inserted into the thermal insulation layer from one end of the thermal insulation layer, and the overlapping parts of the air inlet pipe and the air outlet pipe are evenly arranged with water vapor release pipes in rows, the two ends of the water vapor release pipe are respectively fixedly connected to the air inlet pipe and the air outlet pipe and communicated with each other, and water vapor release grooves are evenly opened circumferentially on the water vapor release pipe, and one end of all the air inlet pipes exposed from the thermal insulation layer is fixedly connected to the air inlet main pipe and communicated with the same, and one end of all the air outlet pipes exposed from the thermal insulation layer is fixedly connected to the air outlet main pipe and communicated with the same.

[0008] Particularly, a humidity sensor is fixedly installed in the water vapor release pipe.

[0009] An air flow sensor is fixedly installed in the water vapor discharge pipe.

[0010] The assembled building roof structure also includes an alarm display terminal, which displays the specific location of each water vapor release pipe and displays the data of the humidity sensor and the data of the ventilation volume sensor in each water vapor release pipe on the water vapor release pipe where the pipe is located.

[0011] Particularly, a first conductive layer with a circular cross section is disposed in both the air inlet pipe and the air outlet pipe, and a resistance heating layer with a circular cross section connected to the first conductive layer is disposed in the water vapor release pipe.

[0012] In particular, a second conductive layer is arranged on the outside of the resistance heating layer in the water vapor release pipe, the middle of the second conductive layer is disconnected, the second conductive layers on both sides of the water vapor release pipe are respectively connected to the first conductive layers in the air inlet pipe and the air outlet pipe, an insulating layer is arranged between the second conductive layer and the resistance heating layer, a wiring tube is fixedly sleeved in the middle position of the water vapor release pipe, the wiring tube is T-shaped, a wiring head is fixedly arranged in the vertical section of the wiring tube, and the two wiring heads are respectively connected to the second conductive layers on the left and right sides of the water vapor release pipe through wires.

[0013] In particular, the lower end of the vertical section of the wiring tube is fixedly connected to a hanging rod by bolts, and a wire head fixedly connected to two wire heads is fixedly installed in the hanging rod. The middle of the hanging rod is hollow, and two wires connected to the two wire heads are arranged in the middle of the hanging rod. A fixed support is fixedly installed at each of the four corners of the lower end of the hanging rod.

[0014] The thickness of the first waterproof layer and the second waterproof layer are both mm.

[0015] The insulating layer is made of rubber.

[0016] Beneficial effects of the present invention: (1) In the present invention, by arranging a thermal insulation layer at the lower end of the main supporting layer, the indoor temperature can be effectively insulated. At the same time, air flow can be injected into the air inlet pipe through the air inlet pipe. The air inlet pipe is arranged on the outside of the frame structure of the building. The air flow in the air inlet pipe enters the air outlet pipe through the water vapor discharge pipe and is finally discharged through the air outlet pipe. The air outlet pipe is arranged in the middle position of the floor frame structure. At the same time, water vapor will enter the water vapor discharge pipe through the water vapor discharge groove, so that the thermal insulation layer can be kept in a dry state. Due to its own gravity and the phenomenon of leaching in concrete, the water will gradually enter the thermal insulation layer and finally enter the water vapor discharge pipe to be discharged. The above technical means can effectively prevent water from accumulating in the concrete, thereby preventing it from eroding and damaging the concrete structure and steel structure in the main supporting layer.

[0017] (2) In the present invention, when the air flows through the water vapor release pipe, the humidity sensor will measure the air humidity in the water vapor release pipe where it is located. When the humidity in a certain water vapor release pipe is significantly greater than the air humidity in other water vapor release pipes, or when the water vapor release pipe reaches the upper humidity limit, it will remind the homeowner that the air humidity there is relatively high and there may be a water leak in the house. At the same time, the air flow sensor will measure the air flow in the water vapor release pipe. The interior of the thermal insulation layer is a foamed structure. Only when the thickness of the thermal insulation layer is thicker can it show good airflow blocking ability. When the air flow of one of the water vapor release pipes is significantly less than the air flow of the other water vapor release pipes, it indicates that the main support layer at the upper end of the water vapor release pipe has cracked.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 12 As shown, the present invention provides a novel assembled building roof structure, including a supporting prefabricated panel 1, characterized in that the supporting prefabricated panel 1 includes a main supporting layer 11, a first waterproof layer 12 is applied to the upper end of the main supporting layer 11, and a multi-layer grid-shaped steel bar structure is fixedly arranged in the main supporting layer 11; The lower end of the main support layer 11 is fixedly connected with a heat-insulating layer 13 by bolts, and the lower end of the heat-insulating layer 13 is coated with a second waterproof layer 14. A ventilation device 2 is provided in the thermal insulation layer 13, and the ventilation device 2 includes an air inlet pipe 21, an air outlet pipe 22 and a water vapor release pipe 23. The air inlet pipe 21 and the air outlet pipe 22 are respectively inserted into the thermal insulation layer 13 from one end of the thermal insulation layer 13, and the overlapping parts of the air inlet pipe 21 and the air outlet pipe 22 are evenly arranged with water vapor release pipes 23 in rows, and the two ends of the water vapor release pipe 23 are respectively fixedly connected to the air inlet pipe 21 and the air outlet pipe 22 and communicate with each other, and water vapor release grooves 231 are evenly opened circumferentially on the water vapor release pipe 23, and one end of all the air inlet pipes 21 exposed from the thermal insulation layer 13 is fixedly connected to the air inlet main pipe 3 and communicated with it, and one end of all the air outlet pipes 22 exposed from the thermal insulation layer 13 is fixedly connected to the air outlet main pipe 4 and communicated with it.

[0023] It should be noted that, in existing buildings, the use of prefabricated panels as supporting structures between floors is a common construction method. Compared with the full pouring of the roof, it has the advantages of convenient and fast construction and low price. However, due to the natural defects of the concrete structure, after a long period of use, it is easy to crack and leak, and water vapor is easy to accumulate in the prefabricated panels of the floor. If the water vapor cannot be discharged in time, it is easy to damage the structure of the prefabricated panels, making the concrete powdery and slag-like, and easily causing the steel layer therein to rust. In the present invention, by providing an insulation layer 13 at the lower end of the main support layer 11, the room can be effectively insulated, and at the same time, air can be injected into the air intake pipe 21 through the air intake main pipe 3. The air inlet pipe 3 is arranged on the outside of the frame structure of the building. The airflow in the air inlet pipe 21 enters the air outlet pipe 22 through the water vapor discharge pipe 23, and is finally discharged through the air outlet pipe 4. The air outlet pipe 4 is arranged in the middle position of the floor frame structure. At the same time, water vapor will enter the water vapor discharge pipe 23 through the water vapor discharge groove 231, so that the insulation layer 13 can be kept in a dry state. Due to its own gravity and the gross leaching phenomenon in the concrete, the moisture will gradually enter the insulation layer 13, and finally enter the water vapor discharge pipe 23 to be discharged. The above-mentioned technical means can effectively prevent moisture from accumulating in the concrete, thereby preventing it from eroding and damaging the concrete structure and the steel structure in the main support layer 11.

[0024] like Fig.11 As shown, a humidity sensor 232 is fixedly installed in the water vapor release pipe 23.

[0025] like Fig.11 As shown, an air flow sensor 233 is fixedly installed in the water vapor release pipe 23.

[0026] As shown in the figure and Fig.12As shown, the prefabricated building roof structure also includes a display alarm terminal, which displays the specific position of each water vapor release pipe 23, and displays the data of the humidity sensor 232 and the data of the ventilation sensor in each water vapor release pipe 23 on the water vapor release pipe 23 where it is located.

[0027] When the airflow passes through the water vapor release pipe 23, the humidity sensor 232 will measure the air humidity in the water vapor release pipe 23 where it is located. When the humidity in a certain water vapor release pipe 23 is significantly greater than the air humidity in other water vapor release pipes 23, or when the water vapor release pipe 23 reaches the upper humidity limit, it will remind the homeowner that the air humidity there is relatively high, and there may be a water leak in the house. At the same time, the air flow sensor 233 will measure the air flow in the water vapor release pipe 23. The interior of the thermal insulation layer 13 is a foamed structure. Only when the thickness of the thermal insulation layer 13 is relatively thick will it show a good airflow blocking ability. When the air flow of one of the water vapor release pipes 23 is significantly less than the air flow of the other water vapor release pipes 23, it indicates that the main support layer 11 at the upper end of the water vapor release pipe has cracked. At the same time, the above unexpected situation will be fed back to the homeowner in a timely manner on the display alarm terminal. At the same time, the location of the house damage can be quickly found through the display alarm terminal, and the house can be repaired quickly.

[0028] like Fig. 9 , Fig.10 and Fig.11 As shown, the air inlet pipe 21 and the air outlet pipe 22 are both provided with a first conductive layer 5 with a circular cross section, and the water vapor release pipe 23 is provided with a resistance heating layer 6 with a circular cross section connected to the first conductive layer 5 .

[0029] The first conductive layer 5 in the air inlet pipe 21 and the air outlet pipe 22 is exposed at the ports of the air inlet pipe 21 and the air outlet pipe 22 where the thermal insulation layer 13 is exposed. The first conductive layer 5 in the air inlet pipe 21 is connected to the live wire, and the first conductive layer 5 in the air outlet pipe 22 is connected to the neutral wire. The water vapor can be heated by the resistance heating layer 6, which has many advantages. On the one hand, it can accelerate the evaporation of water vapor, and at the same time, it can also improve the sensitivity of the humidity sensor 232 to water vapor detection. It can also be used for auxiliary heating in winter to keep the room warm.

[0030] like Figure 8 , Fig. 9 and Fig.11As shown, a second conductive layer 7 is provided on the outer side of the resistance heating layer 6 in the water vapor release pipe 23, and the middle of the second conductive layer 7 is disconnected. The second conductive layers 7 on both sides of the water vapor release pipe 23 are respectively connected to the first conductive layer 5 in the air inlet pipe 21 and the air outlet pipe 22, and an insulating layer 61 is provided between the second conductive layer 7 and the resistance heating layer 6. A wiring tube 234 is fixedly sleeved in the middle position of the water vapor release pipe 23, and the wiring tube 234 is T-shaped. A wiring head 235 is fixedly provided in the vertical section of the wiring tube 234, and the two wiring heads 235 are respectively connected to the second conductive layers 7 on the left and right sides of the water vapor release pipe 23 through wires.

[0031] Through the above technical solution, the circuit layout can be completed when the assembled building roof structure is laid out, eliminating the need to rearrange the indoor circuit.

[0032] like Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the lower end of the vertical section of the wiring tube 234 is fixedly connected to the hanging rod 8 by bolts, and the hanging rod 8 has a wire head 81 fixedly installed therein which is connected to two wire heads 81. The middle of the hanging rod 8 is hollow, and two wires connected to the two wire heads 81 are arranged in the middle of the hanging rod 8. A fixed support 82 is fixedly installed at each of the four corners of the lower end of the hanging rod 8.

[0033] The house can be directly suspended from the ceiling by means of the fixed support 82, and the ceiling can be installed by bolts through the fixed support 82. Meanwhile, the ceiling can be completed by means of wires without affecting the layout of the circuit.

[0034] The thickness of the first waterproof layer 12 and the second waterproof layer 14 are both 3 mm.

[0035] If the waterproof layer is too thin, it will not achieve good waterproof and vapor-tight effect. If the waterproof layer is too thick, it will not only increase the construction cost, but also cause the surface of the waterproof layer to become uneven during the construction process.

[0036] The insulating layer 61 is made of rubber.

[0037] Rubber is relatively cheap and has good insulating effect.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
