Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to rigid thermal insulation roof components. Background Technology

[0002] Rigid insulated roofs refer to roofs that use rigid materials as insulation and waterproofing layers. Rigid insulated roof components are generally suitable for roof waterproofing projects with a waterproofing grade of III, as well as general industrial and civil buildings where the requirements for roof insulation performance are not particularly high. For buildings with small roof structural deformation and small temperature changes, the use of rigid insulated roof components can achieve good insulation results.

[0003] In the actual installation process of rigid insulated roofs, the insulation material is often directly laid or simply bonded to the roof structure. During long-term use, the insulation material is prone to displacement, loosening, or even falling off due to external environmental factors (such as temperature changes, wind and rain erosion, and building structure settlement). Furthermore, because aerated concrete blocks are relatively brittle, the connection strength is insufficient under single bolted connections. In addition, there are gaps between the insulation materials in traditional insulated roof components, which allow heat to easily transfer and reduce the overall insulation effect. Therefore, it is necessary to provide rigid insulated roof components that use steel structures as insulation material fasteners to ensure the stability of the insulation material installation. At the same time, the surface of the insulation material fasteners should be completely covered with insulation filler to ensure the tightness of the insulation structure. Utility Model Content

[0022] In the following description, embodiments of the rigid thermal insulation roofing component of this invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a rigid thermal insulation roofing component according to an embodiment of the present invention, comprising a leveling layer 2 laid on top of a roof structural layer 1; two steel structural beams 3 are laid on top of the leveling layer 2, and the steel structural beams 3 are fixedly connected to the top of the roof structural layer 1 by pre-embedded bolts; multiple thermal insulation and aerated concrete blocks 4 are laid on top of the leveling layer 2; multiple steel structural longitudinal beams 9 are arranged between the two steel structural beams 3; the thermal insulation and aerated concrete blocks 4 are located between the steel structural beams 3 and the steel structural longitudinal beams 9; and the front and rear sides of the steel structural longitudinal beams 9 are... All are connected by threaded bolts 10. The steel longitudinal beams 9 and steel transverse beams 3 are fixedly connected by bolts 10. The use of the steel longitudinal beams 9 and bolts 10 limits and fixes the adjacent two insulated aerated blocks 4, thereby improving the neatness and firmness of the insulated aerated blocks 4 after installation. The inner cavity of the steel longitudinal beams 9 and steel transverse beams 3 is filled with polyurethane foam filler 11. Threaded pins 5 are installed through the front and rear sides of the insulated aerated blocks 4. Threaded pins 5 are installed through the front and rear sides of the steel transverse beams 3. Multiple arc-shaped grooves 6 are provided to accommodate threaded pins 5. Nuts 7 are threadedly connected to the surface of the threaded pins 5 and are pressed against the surface of the steel structure beam 3. An expansion structure 8 is provided on the surface of the threaded pins 5. The expansion structure 8 includes an expansion sleeve 81 fitted onto the surface of the threaded pins 5. Multiple expansion slots 82 are provided on the surface of the expansion sleeve 81. A conical extrusion head 83 is fixedly connected to the end of the threaded pins 5 away from the nut 7. Mounting holes that fit the expansion sleeve 81 are provided on both the front and rear sides of the thermal insulation gas block 4. Multiple anti-detachment protrusions 84 are fixedly connected to the surface of the expansion sleeve 81. Through the setting of the expansion structure 8, the expansion joint 82 and the conical extrusion head 83 work together to expand the expansion sleeve 81 internally. At the same time, with the cooperation of the anti-detachment protrusions 84, the expansion sleeve 81 can be stably installed inside the thermal insulation gas block 4, thereby improving the stability of the thermal insulation gas block 4 after installation. A waterproof layer 12 is laid on the top of the thermal insulation gas block 4, and a protective layer 13 is laid on the top of the waterproof layer 12.

[0024] Working Principle: In use, the user lays a leveling layer 2 on top of the roof structural layer 1, then fixes the steel structural beams 3 to the top of the leveling layer 2 using pre-embedded bolts. The steel structural longitudinal beams 9 are laid between adjacent steel structural beams 3 and connected and fixed using bolts 10. Holes are drilled on the front and rear sides of the insulation and aerated concrete block 4, and expansion sleeves 81 are hammered into the holes. The insulation and aerated concrete block 4 is then laid on top of the leveling layer 2, allowing the threaded pin 5 to engage in the inner cavity of the arc-shaped groove 6. The nut 7 is then screwed onto the surface of the threaded pin 5. Rotating the nut 7 causes the threaded pin 5 to pull. During this pulling process, the threaded pin 5... The expansion sleeve 81 slides and drives the conical extrusion head 83 into the inner cavity of the expansion sleeve 81, which compresses the inner cavity of the expansion sleeve 81, causing the expansion joint 82 to expand. As a result, the expansion sleeve 81 expands its inner diameter, causing the anti-detachment protrusion 84 to be tightly pressed into the pre-drilled hole in the thermal insulation aerated block 4. This allows the expansion sleeve 81 and the threaded pin 5 to be installed and fixed, forming a stable connection with the steel structure beam 3. Then, polyurethane foam filler 11 is filled into the inner cavity of the steel structure beam 3 and the steel structure longitudinal beam 9. After the polyurethane foam filler 11 has completely solidified, a waterproof layer 12 is laid on top of the thermal insulation aerated block 4 and the polyurethane foam filler 11, and a protective layer 13 is set on top of the waterproof layer 12.

[0025] In summary, this rigid thermal insulation roofing component, through the combined use of the roof structure layer 1 and the leveling layer 2, provides a stable installation platform for the thermal insulation aerated concrete block 4. With the combined use of the steel structure beam 3, threaded pins 5 and nuts 7, the thermal insulation aerated concrete block 4 is stably installed on the top of the leveling layer 2, thus achieving the purpose of stable and reliable installation and tight insulation.
