[0021] In order to make the above objects, features and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below. The technical features in each embodiment of the present application can be combined accordingly without conflict.
[0022] As shown in Figure 1 As a preferred embodiment of the present application, the present embodiment provides a single-layer thermal insulation cotton roof structure without steel wire mesh support, which comprises a sliding support 1, a profiled plate 3, a thermal insulation layer 4, a fixing member 5, a connecting member 6 and a purlin 7. Since glass silk cotton has a low thermal conductivity, it can effectively insulate heat transfer and achieve the purpose of thermal insulation, and has excellent elasticity. Therefore, the thermal insulation layer 4 in the present embodiment adopts glass silk cotton. The connecting member 6 can adopt a building foam double-sided tape. The building foam double-sided tape has strong flexibility and excellent sealing performance. During construction, the thermal insulation layer 4 is ensured to be fully attached to the building foam double-sided tape, which can effectively avoid gas release and atomization, provide good sealing effect and improve the thermal insulation effect of the thermal insulation layer 4. In addition, the building foam double-sided tape has high adhesive strength, large peeling force and strong initial adhesion, which can effectively and durably adhere the thermal insulation layer 4 and reduce the falling speed of the thermal insulation layer 4. The purlin 7 can adopt steel or wood. In the present embodiment, the purlin 7 adopts a profiled steel structure, which has high strength and stability. The connecting member 6 is adhered to the surface of the flange of the purlin 7, the thermal insulation layer 4 is laid on the purlin 7 and is adhered and fixed to the purlin 7 through the connecting member 6, and the construction is relatively simple. During construction, the two sides of the fixed thermal insulation layer 4 are aligned with the purlin 7, and the entire thermal insulation layer 4 should be kept in tension to make it flat and not falling in appearance. This prevents the thermal insulation layer 4 from gradually falling with the passage of time, affecting the thermal insulation effect and the overall aesthetic appearance of the roof. Here, the building foam double-sided tape is used to adhere and fix the thermal insulation layer 4 instead of the ordinary single-layer thermal insulation cotton roof structure supported by a steel wire mesh, and there is no need to weld pegs on the purlin 7 for fixing the steel wire mesh, thereby improving the construction convenience.
[0023] In the structure provided in the present embodiment, in order to further reinforce the fixing degree between the thermal insulation layer 4 and the purlin 7, the sliding support 1 is arranged at the position where the thermal insulation layer 4 is located on the purlin 7. As shown in Figure 2As shown, the sliding support 1 comprises a base 101, an upper support 102, a sliding rod 103 and a sliding sheet 104. The base 101 is a quadrilateral with one side open, and a mounting hole is formed on the bottom plate of the base 101, which is in direct contact with the thermal insulation layer 4. The fixing member 5 passes through the mounting hole to fix the sliding support 1 and the thermal insulation layer 4 on the purlin 7 through the thermal insulation layer 4. In this embodiment, the fixing member 5 is a self-tapping screw, which does not need to be pre-drilled and tapped, and can complete drilling, knocking and tightening at one time, greatly saving the installation time and improving the work efficiency. In other embodiments, the fixing member 5 can also be a common screw nut, which is pre-drilled on the purlin 7, and the sliding support 1 is fixed on the purlin 7 through the cooperation of the screw and the nut. The two ends of the open side of the base 101 are respectively horizontally fixedly connected with the upper supports 102, and the upper surface of the upper support 102 is a smooth horizontal surface, which is in direct contact with the profiled sheet 3. The two ends of the sliding rod 103 are horizontally fixed to the middle positions of the two ends of the open side of the base 101, and the sliding sheet 104 is sleeved on the sliding rod 103, and the sliding sheet 104 and the sliding rod 103 are in sliding connection, and the sliding sheet 104 is further provided with a bayonet, which is used for engaging and fixing with the profiled sheet 3.
[0024] In the structure provided in this embodiment, as shown in Figure 1 and Figure 3 A plurality of profiled sheets 3 are covered on the thermal insulation layer 4, and the two sides of each profiled sheet 3 are bent. The bent plates are overlapped and then engaged by special tools along the length direction. The bent part of the profiled sheet 3 and the bayonet on the sliding sheet 104 of the sliding support 1 are also fixed by the overlapping and engagement of the plates. According to different requirements of wind pressure resistance, the engagement angle is divided into 180°, 270° and 360° engagement, and the specific angle depends on the tightness of the engagement. The greater the engagement angle, the higher the wind resistance. The lower surface of the bent part of the profiled sheet 3 is in direct contact with the upper surface of the upper support 102 of the sliding support 1. Since the profiled sheet 3 is directly exposed to the open air environment, it will expand and contract with the change of air temperature. Since the sliding sheet 104 on the sliding support 1 can displace a certain distance on the sliding rod 103, the profiled sheet 3 has the compensation function of thermal expansion and cold contraction, which can avoid the accumulation of pressure caused by temperature change, so as to prevent the profiled sheet 3 from being pulled apart and cracked, and protect the integrity of the structure. The profiled sheet 3 connected by the sliding support 1 can also increase the wind resistance, especially when the plate and the support are engaged to 360 degrees. The middle horizontal part of the profiled sheet 3 which is not bent is in direct contact with the thermal insulation layer 4. The profiled sheet 3 protects the thermal insulation layer 4 from being affected by the external environment, such as wind, rain and sunlight, prolongs the service life of the thermal insulation layer 4, and the composite use of the profiled sheet 3 and the thermal insulation layer 4 can increase the structural strength of the roof and improve the overall load-bearing capacity, while reducing the heat transfer and improving the heat insulation performance of the building.
[0025] In the structure provided by the embodiment, whether to install the waterproof and breathable layer 2 can be selected according to actual needs. If the production environment in the house has low waterproof and moisture-proof requirements or is in a dry area, the waterproof and breathable layer 2 can not be set to reduce the construction cost of the roof. If the production environment in the house has high waterproof and moisture-proof requirements or is in a humid area, the waterproof and breathable layer 2 can be installed to protect the thermal insulation layer 4 from external water vapor and effectively discharge the moisture in the roof structure, and the waterproof and breathable layer 2 can also play a role in insulation to a certain extent. As shown in FIGS. 6 and 7, if the waterproof and breathable layer 2 needs to be installed, the waterproof and breathable layer 2 is laid horizontally on the thermal insulation layer 4 after the thermal insulation layer 4 is laid, and the sliding support 1 is installed on the waterproof and breathable layer 2. The sliding support 1 is fixedly connected with the purlin 7 by the fixing member 5 penetrating through the waterproof and breathable layer 2 and the thermal insulation layer 4. Then the profiled sheet 3 is laid on the waterproof and breathable layer 2, and the profiled sheet 3 directly contacts with the waterproof and breathable layer 2. The splicing between each profiled sheet 3 and the fixing method between the profiled sheet 3 and the sliding support 1 are the same as those of the fixing method when the waterproof and breathable layer 2 is not installed, which will not be described here. Figure 3 and Figure 4
[0026] The embodiment also provides a method for constructing a single-layer thermal insulation cotton roof without steel mesh support, and the steps of the method include the following steps.
[0027] Firstly, before the connecting member 6 is bonded to the upper flange surface of the purlin 7, it is ensured that the upper flange surface of the purlin 7 is clean and dry to ensure the bonding effect of the connecting member 6. After the connecting member 6 is bonded to the purlin 7, the connecting member 6 is uniformly pressed to ensure that the adhesive tape fully contacts with the upper flange surface of the purlin 7, and the adhesive tape is allowed to fully play the role of viscosity after being bonded for a period of time.
[0028] After being rested for a period of time, the thermal insulation layer 4 is laid on the purlin 7. During the laying process, the thermal insulation cotton 4 should be aligned and tensioned to make the thermal insulation cotton 4 flat in appearance. The thermal insulation layer 4 should be fully attached to the connecting member 6, so that the connecting member 6 can pull the tensioned thermal insulation layer 4 to prevent the thermal insulation layer 4 from sagging after being bonded and to ensure the bonding and fixing effect.
[0029] After the thermal insulation layer 4 is laid, the waterproof and breathable layer 2 is laid on the thermal insulation layer 4.
[0030] After the waterproof and breathable layer 2 is laid, the sliding support 1 is arranged on the waterproof and breathable layer 2. The waterproof and breathable layer 2 and the thermal insulation layer 4 are fixed on the purlin 7 by the fixing member 5 penetrating through the waterproof and breathable layer 2 and the thermal insulation layer 4 in cooperation with the sliding support 1.
[0031] Finally, lay the profiled sheet 3 on the waterproof and breathable layer 2, the bending part of each profiled sheet 3 is fixed by the way of interlocking seam along the length direction, the profiled sheet 3 and the sliding support 1 are also fixed by the way of interlocking seam, the angle of interlocking can be adjusted according to the actual construction requirement.
[0032] The above-mentioned embodiment is only a preferred scheme of the present application, but it is not used to limit the present application. The ordinary skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all technical schemes obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present application.
