Description

Technical Field

[0001] This application relates to the technical field of building roof waterproofing and heat insulation, and in particular to a roof waterproofing and heat insulation structure. Background Art

[0002] Roof waterproofing and heat insulation is an important technical link in the construction industry. With the improvement of building energy conservation requirements and the enhancement of environmental protection awareness, the requirements for roof waterproofing and heat insulation performance are becoming increasingly strict. Moreover, the waterproofing and heat insulation of the roof are related to the comfort of the top-floor users. When people buy a house, they will also focus on understanding the waterproofing and heat insulation of the building's top floor.

[0003] And as buildings are getting taller and taller, the intensity of sunlight on the top floor is also higher. As a result, the indoor temperature of the top-floor residents remains high in the hot summer. The usage of refrigeration equipment such as air conditioners increases, and the temperature is difficult to drop in a short time. The electricity consumption also continues to increase, which also leads to fewer and fewer people willing to buy top-floor houses. At present, the common roof waterproofing and heat insulation technologies on the market mainly include traditional asphalt waterproofing membranes, polyurethane spray foam, extruded polystyrene insulation boards, etc. These technologies have their own emphases in waterproofing and heat insulation, but generally have problems such as complex construction, insufficient durability, and poor environmental performance. After long-term use, problems such as leakage and decline in heat insulation performance are likely to occur. In recent years, new materials such as nano-insulating coatings and phase change materials have gradually been applied to the field of roof waterproofing and heat insulation, but there are still limitations such as high cost and difficult construction. Moreover, subsequent repair and maintenance are relatively difficult, time-consuming, and costly. Noise will also be generated during the repair and maintenance process, and the necessary waterproofing and heat insulation functions of the top-floor housing residents' roofs cannot be guaranteed during the repair period. Therefore, a roof waterproofing and heat insulation structure is proposed in view of the above related technical problems. Summary of the Invention

[0004] In order to improve the above problems, this application provides a roof waterproofing and heat insulation structure.

Moreover, its water storage area can automatically discharge water, and the stored water can be recycled. When starting the heat insulation retractable winding box, the sunshade and heat insulation rolling curtain is moved along the rolling curtain track in the rolling curtain guiding box and covers the water storage area. At the same time, it can be sent to the main body of the building roof through the water pump via the water inlet pipe, and heat insulation and heat absorption effects are achieved through water storage. The depth of water storage is monitored by a liquid level gauge, and the environmental detection sensor monitors the light, outdoor temperature, and outdoor air humidity in real time, so as to control the opening and closing of the sunshade and heat insulation rolling curtain according to the outdoor weather environment. And in not-too-hot weather, water storage can be not carried out, or the water on the roof can be discharged from the drain pipe through an electromagnetic drain valve.

[0013] Preferably, a plurality of through drainage holes are arranged on the rolling curtain board. The rolling curtain board is filled with heat preservation cotton, and the outer side of the rolling curtain board is wrapped with a heat preservation board. The outer side of the rolling curtain board is sprayed with a waterproof layer.

[0014] By adopting the above technical solutions, the artificial cost of laying the heat insulation structure is reduced by prefabricating sun protection equipment in the factory. Moreover, the prefabricated sun protection equipment is convenient for installation and construction, and is more convenient for later maintenance and repair, with higher durability. And it can be recycled after the building exceeds its service life and can be reused repeatedly. According to the roof structure, the customized heat insulation retractable winding box is installed and connected to the main body of the building roof, and then according to the weather conditions, the water tank sealing plate group can be selected for installation. The area that does not require heat insulation can be divided according to the layout of the room for use as a drying area. The heat preservation board outside the rolling curtain board and the heat preservation cotton inside it are both used for heat preservation and insulation to prevent a large amount of evaporation of the stored water caused by the heat of light, and the waterproof layer on its surface is used to prevent rainwater or evaporated water droplets from damaging the heat preservation board.

[0015] Preferably, a rolling curtain track is arranged inside the rolling curtain guiding box, and an upper traction conveyor belt and a lower traction conveyor belt are arranged inside the rolling curtain guiding box.

[0018] By adopting the above technical scheme, the heat-insulating retractable winding machine box can be controlled to reel in the sun-proof heat-insulating roller blinds on rainy days. The water inlet pipe is connected to an external water source, and the external water source here can be a rainwater storage barrel on the roof, and can be connected to a drain pipe to achieve the environmental protection of recycled water. Since the upper and lower moving directions of the belt conveyor are opposite during the rotation, the steering drive shaft drives the transmission action at this time, so that the lower side of the upper traction conveyor belt and the upper side of the lower traction conveyor belt move in the same direction, thereby better pulling the traction slider to move.

[0019] 1. Compared with the prior art, the roof waterproof and heat-insulating structure achieves the effect of taking both waterproof and heat-insulating properties into consideration by laying the waterproof structure and the heat-insulating structure separately. The waterproof coating is applied two or three times on the building structure layer of the roof slab, and a waterproof membrane is laid on the waterproof coating. Then, a rigid protective layer is covered on the waterproof membrane. The sun-proof and heat-insulating roller shutter achieves the heat-insulating effect by pulling a sun-proof partition on the roof slab. The sun-proof and heat-insulating roller shutter and the roof slab form a shaded space similar to a bridge hole, and water can be released under the sun-proof and heat-insulating roller shutter to achieve further cooling and heat-insulating effects.

[0020] 2. Compared with the prior art, this kind of roof waterproof and heat-insulating structure reduces the labor cost of laying the insulation structure through factory prefabricated sun-proof equipment, and the prefabricated sun-proof equipment is easier to install and construct, easier to maintain and repair in the later stage, more durable, and can be recycled after the building exceeds its service life, and can be used repeatedly. According to the roof structure, the customized insulation retractable and unreeling reel chassis is installed and connected to the main body of the building roof, and then the water tank sealing plate group is installed according to the weather conditions. According to the layout of the room, the area that does not require insulation can be divided to facilitate its use as a drying area. The insulation board outside the rolling shutter board and the insulation cotton inside it are both used for thermal insulation. The heat from the sunlight causes a large amount of evaporation of the stored water, and the waterproof layer on its surface is used to prevent rain or evaporated water droplets from damaging the insulation board.

[0021] 3. Compared with the prior art, for this roof waterproof and heat insulation structure, the heat insulation structure can be automatically adjusted according to the environment to ensure the comfort of users' residence. It is convenient to retract and extend, and has high safety. Moreover, its water storage area can automatically drain water, and the stored water can be recycled. When starting the heat insulation retractable box, the sunscreen and heat insulation rolling curtain is moved along the rolling curtain track of the rolling curtain guiding box and covers the upper part of the water storage area. At the same time, it can be sent to the main body of the building roof through the water pump via the water inlet pipe, and heat insulation and heat absorption effects can be achieved through water storage. The depth of water storage is monitored by a liquid level gauge, and the light, outdoor temperature and outdoor air humidity are monitored in real time by environmental detection sensors. Thus, the opening and closing of the sunscreen and heat insulation rolling curtain are controlled according to the outdoor weather environment. In relatively not too hot weather, water storage can be not carried out, or the water on the roof can be discharged from the drain pipe through an electromagnetic drain valve. When it is rainy, the heat insulation retractable box can be controlled to retract the sunscreen and heat insulation rolling curtain. The water inlet pipe is connected to an external water source, and here the external water source can be a rainwater storage bucket on the roof and can also be connected to the drain pipe to achieve the environmental protection of recycled water use.

Detailed implementation mode

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] The following is combined with the attached Figures 1 - 11 , and the present application will be further described in detail.

[0026] A roof waterproof and heat insulation structure includes a main body 1 of a building roof, a water tank sealing plate group 2 and a heat insulation retractable box 3. Referring to Figure 1 and Figure 3 , the main body 1 of the building roof includes a roof floor slab 11, a roof floor slab 12 and a protective wall 13, and both the water tank sealing plate group 2 and the heat insulation retractable box 3 are connected between the water supply and drainage protection wall 12 and the protective wall 13, and a water inlet pipe 121 is connected to one side of the water supply and drainage protection wall 12; Among them, rolling curtain guide boxes 34 are connected to the inner sides of both the water supply and drainage retaining wall 12 and the protective retaining wall 13. A cleaning machine box 33 is provided below the heat insulation retractable machine box 3, and the two groups of rolling curtain guide boxes 34 are connected to both ends of the cleaning machine box 33. A sun protection and heat insulation rolling curtain 4 is connected inside the heat insulation retractable machine box 3. The sun protection and heat insulation rolling curtain 4 includes a traction pull plate 41 and multiple groups of rolling curtain plates 42; the main body of the building roof 1 is a flat-roof type roof, which can be a high-rise or a villa building. The roof structure is composed of a roof floor slab 11, a roof floor slab 12, and a protective retaining wall 13. Moreover, the roof structure also includes other building walls, stairwells, and conventional equipment such as lightning protection equipment buildings, which will not be elaborated here. And among them, the water tank sealing plate group 2 is arranged on the side close to the stairs. When the stairwell is on the central axis of the roof, at this time, the structures of the main body of the building roof 1 can be arranged symmetrically on both sides of the stairwell to ensure the waterproof and heat insulation functions of the entire roof. The sun protection and heat insulation rolling curtain 4 achieves the heat insulation effect by pulling a sun protection partition on the roof floor slab 11. And the sun protection and heat insulation rolling curtain 4 and the roof floor slab 11 form a shaded space similar to a bridge opening, and water can be discharged below the sun protection and heat insulation rolling curtain 4 to achieve a further cooling and heat insulation effect. The heat insulation retractable machine box 3 is used to retract and extend the sun protection and heat insulation rolling curtain 4, and when there is a power outage, the sun protection and heat insulation rolling curtain 4 can be manually retracted and extended through the traction pull plate 41.

[0027] Refer to Figure 3 and Figure 4, the roof floor slab 11 includes a building structure layer 111 and a rigid protective layer 114. A waterproof coating 112 is applied to the top of the building structure layer 111. A waterproof coiled material 113 is laid between the waterproof coating 112 and the rigid protective layer 114. A liquid level gauge 15 and an electromagnetic drain valve 14 are connected to the inner wall of the water supply and drainage retaining wall 12, and a drain pipe 141 is connected to the electromagnetic drain valve 14; the building structure layer 111 of the roof floor slab 11 is a reinforced concrete structure of the building foundation, mainly playing the role of load-bearing and protection. The waterproof coating 112 is one of rubber-based waterproof coatings, synthetic resin-based waterproof coatings, and water emulsion-type waterproof coatings, and the waterproof coating 112 needs to be brushed two to three times. The waterproof coiled material 113 is an asphalt-based coiled material, further enhancing the waterproof ability of the roof. The rigid protective layer 114 is a layer of concrete covered on the waterproof coiled material 113. The water inlet pipe 121 is connected to an external water source, and the external water source here can be a rainwater storage bucket on the roof and can be connected to the drain pipe 141 to achieve the environmental protection of recycling water. It is sent to the main body 1 of the building roof through the water inlet pipe 121 by a water pump and achieves the effect of heat insulation and heat absorption through water storage. The depth of water storage is monitored by the liquid level gauge 15. When it is the rainy season or the temperature is relatively low at night in summer, through the monitoring of the liquid level gauge 15, the water on the roof is discharged from the drain pipe 141 by the electromagnetic drain valve 14. Since the temperature at night in summer is relatively high, the remaining water that has not been drained can also be evaporated dry, thus ensuring the dryness of the roof and preventing the roof from being soaked in water for a long time.

[0028] Refer to Figure 1 and Figure 2 , one end of the rolling curtain guide box 34 extends to the inside of the water tank sealing plate group 2. The water tank sealing plate group 2 is inserted between the water supply and drainage retaining wall 12 and the protective retaining wall 13. The water tank sealing plate group 2 includes multiple connecting plug plates 21. Symmetrically arranged splicing plug plates 211 are provided on both sides of the connecting plug plate 21, and multiple connecting plug plates 21 are connected to each other by splicing the splicing plug plates 211 in a pairwise manner; the water tank sealing plate group 2 is a device used to seal the main body 1 of the building roof when storing and discharging water, which can prevent the stored water from entering the stairwell and prevent people from entering the water storage area. It can also divide the area that does not require heat insulation according to the layout of the room for use as a drying area. The connecting plug plate 21 is made of lightweight plastic material, which is convenient for manual handling and installation. It is manually installed before water storage and can be removed when it is not hot to ensure the normal use of the main body 1 of the building roof.

[0029] Refer to Figure 1 and Figure 6, on one side of the heat-insulating retractable box 3 close to the water supply and drainage retaining wall 12, a retractable motor 31 is connected, and one end of the output shaft of the retractable motor 31 is connected with a retractable shaft 311. One end of the sunshade and heat-insulating rolling curtain 4 is fixedly connected inside the retractable shaft 311. The retractable motor 31 drives the retractable shaft 311 to rotate, and during the rotation of the retractable shaft 311, the sunshade and heat-insulating rolling curtain 4 is driven to be retracted and rolled up.

The upper cleaning roller 331 and the lower water droplet scraper 332 are respectively attached to the upper and lower sides of the rolling curtain board 42. The retractable motor 31 can be controlled to open and close according to the monitoring data of the environmental detection sensor 32. The environmental detection sensor 32 includes an ultraviolet sensor for monitoring light, a temperature sensor for monitoring outdoor temperature, and an air humidity sensor for monitoring outdoor humidity, so as to control the opening and closing of the sunshade and heat-insulating rolling curtain 4 according to the outdoor weather environment. When the sunshade and heat-insulating rolling curtain 4 is retracted and rolled up, it first passes through the cleaning box 33, and the rolling curtain board 42 is in a flat state inside the cleaning box 33. The upper cleaning roller 331 is used to remove the dust on the top of the sunshade and heat-insulating rolling curtain 4 inside the cleaning box 33, and the lower water droplet scraper 332 can remove the water droplets adsorbed on the lower surface of the sunshade and heat-insulating rolling curtain 4 by evaporation.

[0031] Refer to Figure 7 and Figure 8 , both sides of the rolling curtain board 42 are connected with retractable connecting plates 44, and a retractable rotating shaft plate 441 is connected between two adjacent retractable connecting plates 44.

An elastic rubber strip connecting door piece 43 is connected between two rolling curtain boards 42. Two adjacent rolling curtain boards 42 are connected through the retractable connecting plates 44 and the retractable rotating shaft plate 441, and the rotation action is realized through the retractable connecting plates 44 and the retractable rotating shaft plate 441. The joint of two adjacent rolling curtain boards 42 is sealed by the elastic rubber strip connecting door piece 43. The connection methods between the rolling curtain board 42 and the retractable connecting plates 44 and the retractable rotating shaft plate 441, as well as the retractable connecting plates 44, the retractable rotating shaft plate 441 and the elastic rubber strip connecting door piece 43 are all common structures of existing rolling door panels, and will not be elaborated here. The driving side plate 45 can realize rapid telescopic movement through the traction sliders 451.

[0032] Refer to Figure 8 and Figure 9The rolling shutter plate 42 is provided with a plurality of drainage holes 46 which pass through from top to bottom. The rolling shutter plate 42 is filled with thermal insulation cotton 421, and the outer side of the rolling shutter plate 42 is wrapped with a thermal insulation board 422, and the outer side of the rolling shutter plate 42 is sprayed with a waterproof layer 423; the drainage holes 46 on the rolling shutter plate 42 are used for drainage facilities in rainy days and due to external damage and power outages to prevent a large amount of rainwater from accumulating on the rolling shutter plate 42, and the thermal insulation board 422 outside the rolling shutter plate 42 and the thermal insulation cotton 421 inside it are both used for thermal insulation to prevent the heat from sunlight from causing a large amount of evaporation of stored water, and the waterproof layer 423 on its surface is used to prevent rainwater or evaporated water droplets from damaging the thermal insulation board 422.

[0033] Reference Figure 5 and Figure 10 The roller shutter guide box 34 is provided with a roller shutter track 341, and the roller shutter guide box 34 is provided with an upper traction conveyor belt 35 and a lower traction conveyor belt 36, the winding connecting plate 44 extends into the roller shutter track 341, and the traction slider 451 is in contact with the upper traction conveyor belt 35 and the lower traction conveyor belt 36; the sun-proof and heat-insulating roller shutter 4 moves and slides in the roller shutter track 341 of the roller shutter guide box 34, and the traction slider 451 is pulled by the upper traction conveyor belt 35 and the lower traction conveyor belt 36 to slide, so as to ensure the automation of the retraction and release of the sun-proof and heat-insulating roller shutter 4, and the height of the traction slider 451 is less than the thickness of the roller shutter plate 42, so as to ensure that when the sun-proof and heat-insulating roller shutter 4 is rolled up, multiple groups of traction sliders 451 will not collide with each other.

[0034] Reference Figure 10 and Figure 11 An upper transmission roller 351 is provided in the upper traction conveyor belt 35, and a lower transmission roller 361 is provided in the lower traction conveyor belt 36, a steering transmission shaft 37 is provided between the upper transmission roller 351 and the lower transmission roller 361, and the output shaft of the winding and unwinding motor 31 is connected to the upper transmission roller 351 through a belt; the lower traction conveyor belt 36 is driven to rotate by the lower transmission roller 361, and the upper traction conveyor belt 35 is driven to rotate by the upper transmission roller 351, and the upper transmission roller 351 is driven to rotate by the winding and unwinding motor 31.

[0035] Reference Figure 10 and Figure 11, on the outer sides of the upper driving roller 351 and the steering transmission shaft 37, transmission gears 371 are sleeved through shaft keys, and the two groups of transmission gears 371 are meshed with each other. The steering transmission shaft 37 and the lower driving roller 361 are connected by a belt. During the rotation of the upper driving roller 351, the steering transmission shaft 37 is driven to rotate through the transmission gear 371. At this time, the rotation direction of the steering transmission shaft 37 is opposite to that of the upper driving roller 351, and the lower driving roller 361 can be driven to rotate by the steering transmission shaft 37 through the belt. Since the moving directions of the upper and lower surfaces of the belt conveyor are opposite during rotation, through the transmission action of the steering transmission shaft 37 at this time, the moving directions of the lower surface of the upper traction conveyor belt 35 and the upper surface of the lower traction conveyor belt 36 are the same, so as to better traction the traction slider 451 to move.

[0036] The working process of this application is as follows: First, apply two to three coats of waterproof coating 112 on the building structure layer 111 of the roof floor slab 11, lay waterproof coiled material 113 on the waterproof coating 112, then cover a layer of rigid protective layer 114 on the waterproof coiled material 113, and install and connect the customized heat insulation retractable box 3 on the main building roof 1 according to the roof structure. Then, select to install the water tank sealing plate group 2 according to the weather conditions; In hot weather, the connection plug plate 21 can be manually carried and installed, and the connection plug plates 21 are inserted and connected in sequence to form an enclosed structure with an open top on the main building roof 1. After the installation is completed, the heat insulation retractable box 3 can be started to move the sunshade and heat insulation rolling curtain 4 along the rolling curtain track 341 of the rolling curtain guide box 34 and cover it above the water storage area. At the same time, water can be sent to the main building roof 1 through the water inlet pipe 121 via a water pump, and heat insulation and heat absorption effects can be achieved through water storage. The depth of water storage is monitored by the liquid level gauge 15. The sunshade and heat insulation rolling curtain 4 and the roof floor slab 1 form a shaded space similar to a bridge hole, and further cooling and heat insulation effects can be achieved through the heat absorption effect of water storage; In daily life, the environmental detection sensor 32 monitors the light, outdoor temperature and outdoor air humidity in real time, so as to control the opening and closing of the sunshade and heat insulation rolling curtain 4 according to the outdoor weather environment. In weather that is not too hot, water storage can be not carried out, or the water on the roof can be discharged from the drain pipe 141 through the electromagnetic drain valve 14. When it is rainy, the heat insulation retractable box 3 can be controlled to retract the sunshade and heat insulation rolling curtain 4; The rewinding and unwinding motor 31 drives the rewinding and unwinding shaft 311 to rotate. During the rotation of the rewinding and unwinding shaft 311, the sunscreen and heat insulation rolling curtain 4 is wound up. At the same time, the rewinding and unwinding motor 31 drives the upper transmission roller 351 to rotate. During the rotation of the transmission roller 351, the steering transmission shaft 37 is driven to rotate through the transmission gear 371. At this time, the rotation direction of the steering transmission shaft 37 is opposite to that of the upper transmission roller 351.
