Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a roof interlayer water vapor exhaust device and a construction method. Background Art

[0002] Concrete roof insulation layer is easy to store water. In summer, when the temperature is high, water changes into water vapor. The water vapor cannot be discharged, which easily causes the concrete protective layer of the roof to arch and crack. In the current construction project, the roof contains a waterproof layer, an isolation layer, an insulation layer, and a concrete protective layer. There is water accumulation or water stains in the layers above the waterproof layer and below the concrete protective layer that cannot be completely removed, and there are cracks in the concrete protective layer, which causes rainwater to enter. When the temperature is too high in summer, water turns into water vapor, which easily causes the concrete protective layer to arch and crack. If this continues, it may affect the service life of the roof waterproof layer and cause roof seepage. Therefore, the water vapor in it needs to be discharged. The current roof ventilation groove method is to fill pebbles between the insulation boards and cover the top with waterproof membrane. The construction speed is slow, the material procurement is difficult, the construction is inconvenient, and the cost is high. The roof ventilation device can be produced with stainless steel plates, galvanized plates, and PVC materials to ensure its strength. The manufacturer can produce in batches, which is convenient for procurement, convenient for on-site transportation, and simple on-site assembly. The clean energy of solar power generation is used to accelerate the discharge of water vapor in the breathable layer. It is beautiful after installation, and the construction saves labor and material costs.

[0003] Therefore, the ventilation system and construction method for building roofs can effectively remove water vapor in the building insulation layer to prevent the concrete protective layer of the roof from arching and cracking due to the inability to remove water vapor. The invention aims to make the construction of the roof ventilation system convenient and fast, use solar clean energy, speed up the discharge of interlayer water vapor, reduce the risk of cracking and repair, and effectively save costs.

[0004] At present, the installation and construction methods of building roof ventilation systems are to fill the insulation layer and insulation board with pebbles and other materials. Water vapor flows from the gaps between the pebbles to the risers, and the risers are naturally discharged. The risers are fixed with mortar. When pouring the roof concrete protective layer, if the workers are not careful, the risers are prone to tilt, and concrete is easy to flow into the pipes and cause blockage.

Through the design of the threaded column and the support plate, precise height adjustment is achieved, the adaptability of the system is enhanced, the on-site installation process is simplified, and the construction efficiency is improved. At the same time, the threaded column and the rough surface support plate ensure the stability and anti-displacement ability of the system, avoiding the situation that the vertical pipe in the traditional breathable groove is often skewed or blocked when pouring the concrete protective layer due to loose mortar fixation.

[0027] 3. The present invention not only provides power for the exhaust blades by introducing solar panels, but also embodies the concept of green building as an application of environmentally friendly energy. The solar panels are connected to the fan blades through wires to form a small independent power supply system, which utilizes free solar energy resources and reduces the long-term operating cost of the system.

The present invention sets a convex block with a wide bottom and narrow top structure inside the ventilation pipe head, and its four sides are sloped, which helps to guide and lift the water vapor flow, reduce air flow conflicts, and improve exhaust efficiency. In addition, ventilation holes are opened on both sides of the horizontal ventilation groove pipe to ensure that water vapor can smoothly enter the system. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to solve the problem of water vapor accumulation in the existing roof insulation layer causing structural roof damage, inconvenient dehumidification operation and high cost, please refer to Figure 1-4 , this embodiment provides the following technical solutions:

[0036] A roof interlayer water vapor exhaust device includes a breathable pipe head 1, which is arranged at the intersection of each dividing seam. Four notches 9 are arranged in the horizontal direction of the breathable pipe head 1, and the two ends of the horizontal breathable groove tube 2 are respectively connected to the notches 9 on the adjacent breathable pipe heads 1.

[0037] The top surface and two side surfaces of the horizontal ventilation groove tube 2 are closed, and the bottom surface of the horizontal ventilation groove tube 2 is open. Ventilation holes 10 for allowing water vapor to pass through are opened on both sides of the horizontal ventilation groove tube 2. The height of the horizontal ventilation groove tube 2 matches the insulation board.

[0038] The horizontal ventilation tube 2 is located between the insulation boards. The top of the horizontal ventilation tube 2 is covered with a waterproof coiled material, which extends beyond the two sides of the horizontal ventilation tube 2 by a certain distance.

[0039] The interior of the air pipe head 1 is hollow and a riser interface 8 is provided on the top. The top of the riser interface 8 is connected to the exhaust riser 3. A bend 4 is provided on the top of the exhaust riser 3. The bend 4 is bent 180 degrees. One end of the bend 4 is connected to the exhaust riser 3, and the other end is connected to the straight pipe 5. A fan blade 11 is provided inside the straight pipe 5. A solar panel 6 is installed on the top of the bend 4, and the solar panel 6 is connected to the fan blade 11 through an electric wire 7.

[0040] Specifically, under sunlight, the solar panel 6 collects light energy and converts it into electrical energy, which is then conducted to the motor through the wire 7 to drive the fan blade 11 to rotate. The water in the insulation layer is converted into water vapor when the temperature is high, and flows into the horizontal ventilation groove pipe 2 through the air vent 10, and flows into the ventilation pipe head 1 along the horizontal ventilation groove pipe 2. Then, the water vapor flows out from the exhaust riser 3 and the bend pipe 4 under the lifting effect of the slope of the convex block 12, thereby achieving the effect of accelerating the conversion of water in the insulation layer into water vapor for discharge.

[0041] The air pipe joint 1 is made of galvanized material or PVC material, the exhaust riser 3 and the elbow 4 are galvanized pipes, stainless steel pipes or PVC pipes. The air pipe joint 1, the horizontal air trough pipe 2, the exhaust riser 3, the elbow 4 and the straight pipe 5 can be mass-produced and assembled after being transported to the site as semi-finished products.

[0042] The vent pipe head 1, the horizontal vent pipe 2, the exhaust riser 3, the elbow 4 and the straight pipe 5 can be connected by a socket connection, and the connection nodes are sealed with tape to prevent water vapor from overflowing.

[0043] In order to prevent the airflows entering the breathable pipe head 1 from four directions from merging to generate turbulence and interfere with the discharge of water vapor, a protrusion 12 is fixed at the center of the inner bottom surface of the breathable pipe head 1. The protrusion 12 and the breathable pipe head 1 are an integrated structure. The protrusion 12 is a structure that is wide at the bottom and narrow at the top. The four sides of the protrusion 12 are slopes. After the water vapor reaches the middle of the breathable pipe head 1, the four slopes of the protrusion 12 can lift the water vapor to form an upward airflow and then converge, thereby reducing airflow conflicts.

[0044] A threaded groove 13 is provided at the bottom center of the air pipe head 1, and the threaded groove 13 extends longitudinally inside the protrusion 12. The threaded groove 13 cooperates with the threaded column 14. A support plate 15 is fixed to the bottom end of the threaded column 14. The bottom of the support plate 15 is provided with a rough surface. When the height of the air pipe head 1 and the horizontal air groove tube 2 needs to be adjusted, the support plate 15 is screwed to adjust the screw-out length of the threaded column 14, and the support plate 15 is placed on the roof. The air pipe head 1 is supported by the support plate 15 and the threaded column 14. The rough surface of the support plate 15 can increase the friction between it and the roof to prevent sliding and displacement after installation.

[0045] A construction method for a roof interlayer water vapor exhaust device, used to realize a roof interlayer water vapor exhaust device, comprises the following steps:

[0046] Step 1: Place the vent pipe connector 1 at a designated location, and adjust the height of the vent pipe connector 1 by adjusting the screw-out length of the threaded column 14;

[0047] Step 2: Connect the horizontal ventilation trough 2 to the notch 9, lay the roof insulation board on both sides of the horizontal ventilation trough 2, and after the laying is completed, lay a layer of waterproof membrane on the horizontal ventilation trough 2, and the membrane extends 10 cm from both sides of the horizontal ventilation trough 2;

[0048] Step 3: Connect the exhaust riser 3 to the riser interface 8;

[0049] Step 4: After the roof concrete protective layer is poured, the elbow 4 is connected to the upper end of the exhaust riser 3;

[0050] Step 5: Connect the straight pipe 5 with the fan blade 11 to the other end of the curved pipe 4;

[0051] Step 6: Install the solar panel 6 on the upper side of the curved pipe 4;

[0052] Step 7: Connect the wire 7 to connect the solar panel 6 and the motor driving the fan blade 11.

[0053] Working principle: The ventilation pipe head 1 is set at the intersection of each partition seam, and is hollow inside and has four horizontal notches 9 for connecting the horizontal ventilation slot pipe 2. The horizontal ventilation slot pipe 2 is closed on the top and both sides, open on the bottom, and has ventilation holes 10 on the side, which matches the height of the insulation board, is located between the insulation boards, and is covered with waterproof membrane to prevent external moisture from penetrating.

[0054] When the temperature rises, the moisture in the insulation layer is converted into water vapor, enters the horizontal ventilation groove tube 2 through the air holes 10, and then flows along the groove tube into the ventilation pipe head 1. A convex block 12 with a lower wide and upper narrow structure is provided inside the ventilation pipe head 1, which helps to guide the airflow to flow upward, reduce airflow conflicts, and improve exhaust efficiency.

[0055] Then, the water vapor enters the exhaust riser 3 from the riser interface 8 at the top of the air permeable pipe head 1, and then is guided to the straight pipe 5 through the 180-degree curved pipe 4. The solar panel 6 is installed above the curved pipe 4 to collect sunlight and convert it into electrical energy, which is transmitted to the motor in the straight pipe 5 through the wire 7 to drive the fan blade 11 to rotate, generate suction force, and accelerate the discharge of water vapor.

[0056] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0057] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
