Description

Technical Field

[0001] The invention belongs to the technical field of roof thermal insulation, and in particular relates to a roof waterproof thermal insulation structure and a construction method thereof. Background Art

[0002] Roof insulation technology is an important means to improve energy efficiency and living comfort in buildings. It mainly includes the use of various insulation materials and construction methods to achieve the thermal protection function of the roof.

[0003] Roof insulation technology plays an important role in modern construction projects. It not only helps to improve the energy efficiency of buildings, but also improves the quality of indoor environment. By rationally selecting insulation materials, optimizing design, strict construction management and regular maintenance and inspection, the performance of the roof insulation system can be fully utilized to provide residents with a more comfortable and energy-saving living environment.

[0004] Problems with existing technologies:

[0005] Today's roof insulation technology mostly uses insulation materials installed on the roof. However, in the hot summer, excessive insulation will cause the indoor environment to be stuffy and cause a burden on the air conditioning system. In addition, although the insulation layer can effectively reduce heat loss and keep the roof dry all year round, it may also cause some potential problems. For example, the insulation material has good thermal insulation performance in a dry state, but when the material is damp, the presence of moisture in its pores will significantly increase the thermal conductivity, thereby reducing the insulation effect. Especially in the case of a closed insulation layer, if the moisture content of the insulation material is not controlled during construction, it may cause the moisture inside the insulation layer to evaporate, causing bubbling in the waterproof membrane, and then leading to local leakage. After the insulation material is deformed, the part that adheres to the roof will also cause damage to the roof structure. Summary of the invention

[0006] The purpose of the present invention is to provide a roof waterproof and heat-insulating structure and a construction method thereof, which can achieve roof insulation and effectively improve the heat insulation performance of the roof to cope with changes in ambient temperature.

[0009] The adjustment bracket comprises a plurality of mounting frames which are continuously spliced ​​and installed, a first movable connecting member is installed on a single mounting frame, a second movable connecting assembly corresponding to the first movable connecting member is installed on another mounting frame corresponding to the first movable connecting member, and at least two bearings and bearing seats are arranged on the two opposite mounting frames;

[0010] At least two second movable connection components are fixedly installed at the bottom of a single thermal insulation board, and two first movable connection members are slidably installed corresponding to the second movable connection components.

The motor is fixedly installed on the side of the positioning plate, and the adjustment bracket and the positioning plate are both installed on the roof.

[0014] The slide groove and the top of the second movable connection component are both fixed to the bottom of the insulation board, and both sides of the top of the first movable connection component are provided with protrusions for coupling and sliding installation inside the slide grooves on both sides.

[0015] The bearing and the bearing seat are fixedly installed inside the mounting frame or at the intersection of two adjacent mounting frames by bolts. At least two of the bearings and the bearing seats are used to fix the central axis of the rotation of the rotating shaft. The mounting frame is adapted to be equipped with a second movable connection component and a first movable connection member and an accommodating adjustment sleeve. The first movable connection member, the second movable connection component and the inner wall of the accommodating adjustment sleeve are clearance-matched.

[0016] A plurality of collars are arranged on the outer side of the eccentric wheel, and the eccentric wheel is rotatably mounted inside the first movable connecting member or the second movable connecting assembly through the collars.

[0017] A roof waterproof thermal insulation board is installed on the top of the roof waterproof thermal insulation structure, comprising a plurality of groups of spliced ​​thermal insulation boards and an isolation space formed by the thermal insulation boards and the roof;

[0018] The insulating empty layer is vertically raised and lowered at both sides of the heat-insulating plate by means of the adjusting brackets on both sides of the same group, so that the inclination angle of the heat-insulating plate is changed, and the insulating empty layer is opened and closed.

[0019] A mounting plate is also arranged between the thermal insulation board and the adjustment bracket, and clamping strips for coupling with the two ends of the thermal insulation board are arranged on the inner sides of the two ends of the mounting plate.

[0020] A slot is provided between adjacent insulation boards, and a filling ring that fits the inner wall is inserted into two adjacent slots. A connecting strip is inserted into the filling ring through interference fit, and both ends of the connecting strip are fixed to the two ends of the mounting plate by screws.

[0021] The opening height of the clamping groove outside the thermal insulation board is smaller than the vertical height of the clamping groove inside the thermal insulation board.

[0022] A construction method for a roof waterproof and heat-insulating structure, using the roof waterproof and heat-insulating structure and the roof waterproof and heat-insulating board, comprises the following steps:

[0023] S1. Locate the roof punching position according to the length and width of the insulation board and the length of the mounting frame;

[0024] S2. Install and splice the mounting frame using expansion bolts;

[0025] S3, installing a first movable connection piece and a second movable connection assembly at corresponding positions on the pre-assembled insulation board, and sleeve an upper cover for buckling on the top of the mounting frame on the first movable connection piece and the second movable connection assembly;

[0026] S4, when penetrating the rotating shaft, the bearing and the bearing seat are sleeved at the position of the bearing accommodating sleeve on the corresponding mounting frame, and a plurality of first movable connecting members or a plurality of second movable connecting components are installed through the rotating shaft, and the rotating shaft is a single-section or multi-section threaded assembly structure;

[0027] S5. Install the prefabricated and assembled insulation board on the mounting frame, and fix the upper cover and the mounting frame;

[0028] S6. The same end of the multiple rotating shafts is sleeved with the positioning plate, the transmission wheel, the end bearing and the bearing seat in sequence, and the motor is installed with bolts;

[0029] S7, connecting the output end of the motor to the plurality of transmission wheels using a transmission belt transmission sleeve;

[0030] S8. Debug and adjust the bracket to adjust the flip angle of the insulation board, and the installation is completed.

[0031] The technical effects achieved by the present invention are:

[0032] According to the present invention, when a plurality of thermal insulation boards are in a closed splicing state, an insulating space layer is formed between the plurality of thermal insulation boards and the roof. When the thermal insulation performance of the thermal insulation boards is difficult to meet the use requirements, the thermal insulation boards can be prevented from directly transmitting the temperature to the roof. When the temperature under sunlight is high, air flow can be achieved through the set insulating space layer, so that the temperature between the thermal insulation board and the roof can be quickly dissipated. By adjusting the bracket to drive the thermal insulation board to tilt or continuously fan, the air flow speed inside the insulating space layer can be made faster.

[0033] According to the present invention, when the altitude of the sun decreases, the temperature generated by its irradiation on the ground will also decrease. At this time, the heat dissipation of the ground temperature is slow, and the temperature of the roof cannot be quickly diffused, causing stuffiness in the house. By adjusting the bracket to drive the thermal insulation board to tilt, the heat inside it can be quickly diffused through the tilt of the thermal insulation board, thereby increasing the cooling speed of the roof.

[0034] The present invention adjusts the heat preservation board to a closed state. When the weather is hot, the heat preservation board is turned over to allow the heat to directly irradiate the roof. When the temperature drops, the heat preservation board is turned over to make the inside of the isolation space layer in a closed state. The roof is insulated by the heat preservation board to avoid heat loss. In rainy and snowy weather, the heat preservation board is in a normally closed state to achieve a heat preservation effect.

[0050] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0051] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] In addition, the waterproofing mentioned in the present application does not mean preventing all rainwater from scouring and rainwater leakage through the insulation board 1 in the present application, but through the setting of the insulation board 1, a waterproofing effect can be achieved on rainwater directly scouring the roof.

[0053] Embodiment 1:

[0054] like Figure 4-7As shown, a roof waterproof and heat-insulating structure includes a plurality of adjustment brackets 4 for adjustably mounting a plurality of mutually spliced ​​insulation panels 1, the adjustment brackets 4 include a plurality of continuously spliced ​​mounting frames 41, a first movable connecting member 42 is mounted on a single mounting frame 41, a second movable connecting member 43 corresponding to the first movable connecting member 42 is mounted on another corresponding mounting frame 41, and no less than two bearings and bearing seats 47 are arranged on the two opposite mounting frames 41.

[0055] Among them, multiple adjustment brackets 4 are arranged in parallel, and the assembly length of the mounting frame 41 can be adapted to its length according to the roof waterproofing requirements, and is used to fix the bottom corners of the mounting frame 41 through expansion bolts. The setting spacing needs to at least meet the overall support requirements of the adjustment bracket 4.

[0056] Furthermore, the correspondence between the first movable connection member 42 and the second movable connection component 43 is that they are fixedly installed on the bottom surface of the insulation board 1 and are both located on parallel lines, or the insulation board 1 can change its inclination angle through a lifting and lowering. The number of the first movable connection member 42 and the second movable connection component 43 installed is set to at least one group, and one group includes a first movable connection member 42 and a second movable connection component 43. However, considering that in actual use, the insulation board 1 is affected by wind, rain or other natural meteorological factors, there are certain requirements for the installation stability of the insulation board 1. Therefore, the first movable connection member 42 and the second movable connection component 43 are set to at least two groups, and both are fixedly installed at the top foot position at the bottom of the insulation board 1.

[0057] Therefore, please refer to Figure 8-11 At least two second movable connection components 43 are fixedly installed at the bottom of a single insulation board 1, and two first movable connection members 42 are slidably installed corresponding to the second movable connection components 43. Eccentric wheels 421 are rotatably installed at the bottom of the second movable connection components 43 and the first movable connection members 42, and the eccentric wheel 421 is penetrated by an eccentric hole 422 at a position offset from the center. The eccentric hole 422 is used for coupling and plugging a rotating shaft 48, and the rotating shaft 48 is connected through a transmission by a set motor 3.

[0058] The initial positions of the two second movable connection components 43 and the eccentric hole 422 at the bottom of the first movable connection member 42 are located at opposite sides of the center of the eccentric wheel 421 .

[0059] According to the above structure, its working principle is:

[0060] When the motor 3 drives the two rotating shafts 48 synchronously, the rotating shafts 48 respectively drive the two corresponding eccentric wheels 421 to rotate, so that the second movable connection component 43 and the first movable connection component 42 move in a vertical direction, driving the inclination angle of the thermal insulation board 1 to change.

[0061] For details, please refer to Fig.11 In the embodiment, under the premise that the position of the rotating shaft 48 is fixed, when the rotating shaft 48 rotates, it drives the two relative eccentric wheels 421 to rotate, so that the eccentrically arranged eccentric wheels 421 drives the first movable connection member 42 or the second movable connection member 43 to move up and down in the vertical direction. In addition, during the movement, in order to avoid the change in the spacing, a group of slide grooves 44 are set, and the slide grooves 44 and the top of the second movable connection member 43 are fixed to the bottom of the insulation board 1. Both sides of the top of the first movable connection member 42 are provided with protrusions for coupling and sliding installation inside the slide grooves 44 on both sides. When the insulation board 1 tilts, the spacing between the first movable connection member 42 and the top of the second movable connection member 43 changes. Through the sliding installation of the slide grooves 44 and the top of the first movable connection member 42, the adaptability problems between the two first movable connection members 42 and the second movable connection member 43 are avoided.

[0062] According to the above structure, the insulation principle is:

[0063] When multiple insulation boards 1 are in a closed splicing state, an insulating space layer is formed between the multiple insulation boards 1 and the roof. When the insulation performance of the insulation board 1 is difficult to meet the use requirements, the insulation board 1 can be prevented from directly transmitting the temperature to the roof. By setting the insulating space layer, when the temperature of sunlight is high, the ground temperature is generally measured to be not less than 38°C. At this time, air flow can be achieved through the set insulating space layer, so that the temperature between the insulation board 1 and the roof can be quickly dissipated. By adjusting the bracket 4 to drive the insulation board 1 to tilt or continuously fan, the air flow speed inside the insulating space layer can be faster.

[0064] However, after the sun's altitude decreases, the temperature generated by its irradiation on the ground will also decrease. At this time, the ground temperature dissipates heat slowly, and the roof temperature cannot spread quickly, causing stuffiness in the house. By adjusting the bracket 4 to drive the insulation board 1 to tilt, the heat inside it can be quickly diffused through the tilt of the insulation board 1, thereby increasing the cooling speed of the roof.

[0065] In addition, when it is winter when the perceived temperature is relatively cold, or when it is at high latitudes or high altitudes, the thermal insulation board 1 is adjusted to a closed state, and closed positioning plates 2 are provided on the sides of multiple thermal insulation boards 1. When the weather is hot, the thermal insulation board 1 is flipped over to allow heat to directly irradiate the roof. When the temperature drops, the thermal insulation board 1 is flipped over to allow the interior of the isolation layer to be closed. The thermal insulation board 1 is used to insulate the roof to avoid heat loss. When it is rainy or snowy, the thermal insulation board 1 is in a normally closed state to achieve a thermal insulation effect.

[0066] In order to meet the automatic adjustment requirements of the above-mentioned various conditions, the automatic adjustment of the inclination of the thermal insulation board 1 can be achieved by installing and setting a temperature sensor, a rain sensor, and a humidity sensor.

[0067] Further references Figure 4-7 A positioning plate 2 is installed on one side of the multiple spliced ​​insulation boards 1, and the positioning plate 2 is perpendicular to the installation direction of the multiple adjustment brackets 4. The motor 3 is fixedly installed on the side of the positioning plate 2, and the adjustment bracket 4 and the positioning plate 2 are both installed on the roof.

[0068] Furthermore, the bearings and bearing seats 47 are fixedly installed inside the mounting frame 41 or at the junction of two adjacent mounting frames 41 by bolts. At least two bearings and bearing seats 47 are used to fix the central axis of rotation of the rotating shaft 48 to achieve the positioning of the rotating shaft 48. The mounting frame 41 is adapted to be equipped with a second movable connection component 43 and a first movable connection component 42, and an accommodating adjustment sleeve 45 is provided. The first movable connection component 42, the second movable connection component 43 and the inner wall clearance of the accommodating adjustment sleeve 45 are matched.

[0069] Please refer to Figure 8 and Fig. 9 A plurality of collars 423 are provided on the outer side of the eccentric wheel 421. The eccentric wheel 421 is rotatably mounted inside the first movable connecting member 42 or the second movable connecting member 43 through the collars 423. The eccentric wheel 421 is tested for rapid rotation through the collars 423.

[0070] According to the structure in Example 1, the insulation board 1 includes but is not limited to heat-reflecting insulation boards, heat-absorbing insulation boards, and vacuum-insulating insulation boards. The heat-reflecting insulation boards use materials that can reflect sunlight or boards or coatings with reflective functions, while the heat-absorbing insulation boards can be solar panels or solar water heating pipes. The vacuum-insulating insulation boards can be an insulation board whose interior is set to be vacuum, or whose interior is connected to a vacuum device for vacuuming.

[0071] Embodiment 2:

[0072] When the material of the insulation board 1 is replaced with a heat-reflecting insulation board, heat isolation can be achieved. When the insulation board 1 is a heat-absorbing insulation board, such as a solar panel or a solar water pipe, heat isolation and absorption can be achieved, thereby improving the utilization of thermal energy and solar energy resources.

[0073] Please refer to Figure 1-3 A roof waterproof insulation board is installed on the top of the roof waterproof insulation structure, including a plurality of groups of spliced ​​insulation boards 1 and an isolation space formed by the insulation boards 1 and the roof.

[0074] Further, according to the above structure, the principle is:

[0075] The height of the insulation board 1 on both sides is vertically raised and lowered by the adjusting bracket 4 of the same group, so that the inclination angle of the insulation board 1 is changed, and the isolation layer is opened and closed, thereby realizing the control and adjustment of heat absorption and heat dissipation on the roof, avoiding the singleness of the fixed insulation layer, and avoiding direct damage to the roof after the insulation layer is damaged and deformed. The installation method of the adjusting bracket 4 in the present application can be to reserve a mounting hole on the roof for installing the adjusting bracket 4, or to install the adjusting bracket 4 by pouring a protruding cement block on the roof.

[0076] When installing the thermal insulation board 1, firstly, the thermal insulation board 1 can be directly installed on the top of the adjustment bracket 4, or a partition can be provided. The installation methods include but are not limited to adhesive installation and bolt fixing installation.

[0077] Furthermore, in the bolt-fixed installation method, specifically, a mounting plate 11 is arranged between the thermal insulation board 1 and the adjustment bracket 4 , and clamping strips 111 for coupling with the two ends of the thermal insulation board 1 are arranged on the inner sides of the two ends of the mounting plate 11 .

[0078] In addition, there are card slots 12 between adjacent insulation boards 1, and filling rings 13 that fit with the inner wall are inserted into the two adjacent card slots 12. A connecting strip 14 is inserted into the filling ring 13 through interference fit, and both ends of the connecting strip 14 are fixed to the two ends of the mounting plate 11 by screws 15.

[0079] In addition, the opening height of the slot 12 on the outside of the insulation board 1 is smaller than the vertical height of the slot 12 inside the insulation board 1, so that the connection between the connecting strip 14 and the slot 12 can be achieved. The specific shape of the slot 12 includes but is not limited to a strip structure of a prism or cylinder spliced ​​with a rectangular strip, and the vertical width of the prism and cylinder is greater than the rectangular strip structure.

[0080] A construction method for a roof waterproof and heat-insulating structure, using the roof waterproof and heat-insulating structure and the roof waterproof and heat-insulating board, comprises the following steps:

[0081] S1, locate the roof punching position according to the length and width of the insulation board 1 and the length of the mounting frame 41;

[0082] S2, installing and splicing the mounting frame 41 using expansion bolts;

[0083] S3, installing the first movable connecting member 42 and the second movable connecting assembly 43 at corresponding positions on the pre-assembled insulation board 1, and sleeve the upper cover for buckling on the top of the mounting frame 41 on the first movable connecting member 42 and the second movable connecting assembly 43;

[0084] S4, when the rotating shaft 48 is penetrated, the bearing and the bearing seat 47 are sleeved at the position of the bearing accommodating sleeve 46 on the corresponding mounting frame 41, and a plurality of first movable connecting members 42 or a plurality of second movable connecting members 43 are penetrated and installed, and the rotating shaft 48 is a single-section or multi-section threaded assembly structure;

[0089] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
