Technical Field

[0001] This utility model belongs to the field of spray-coated thermal insulation roofing technology, and in particular relates to spray-coated thermal insulation roofing. Background Technology

[0002] Polyurethane is an ideal choice for spray-coated roof insulation construction. It can be directly sprayed and foamed for roof substrates of various shapes, whether flat, vertical or top, and whether round, spherical or other irregular complex objects, without the need for expensive mold manufacturing costs.

[0003] The shape of the sprayed foam insulation layer is consistent with the shape of the roof substrate, which can effectively protect the internal core material. In order to enable the sprayed foam to adhere better to the roof substrate, a sprayed insulation roof is designed. This structure adds wire mesh to the roof substrate, which enables the foam to grip and adhere to the roof substrate, thus making the connection between the foam insulation layer and the roof substrate tighter. Utility Model Content

[0007] Preferably, the opposite ends of the round rods extend through the surface of the convex head and are welded with circular plates, and a rubber gasket is fixedly connected to the top of the inner cavity of the convex head.

[0008] Preferably, the surface of the positioning bolt is welded with a positioning hexagonal piece, and the surface of the positioning bolt is threaded, with the thread located below the positioning hexagonal piece.

[0009] Preferably, a limiting ring is welded to the surface of the threaded tube, and an annular groove is formed in the inner cavity of the positioning head.

[0010] Preferably, the surface of the limiting ring is rotatably connected to the inner cavity of the annular groove, and a hexagonal head is welded to the top of the threaded tube.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a convex head and a positioning bolt, and the positioning head and the threaded bolt work together to fix the wire mesh to the top of the building. Then, foam is sprayed onto the roof base layer. At the same time, the foam will cover the surface of the wire mesh, so that the foam sprayed onto the roof base layer can better adhere to the roof base layer, so that the connection between the foam insulation layer and the roof base layer is tighter.

The convex head 5 is located on the left and right sides of the wire mesh 2. The inner cavity of the threaded tube 4 is threadedly connected to the surface of the threaded bolt 6. The beveled head 10 is located below the semi-circular head 8. The opposite ends of the two round rods 9 are both inserted into the surface of the convex head 5 and welded with round plates 12. The top of the inner cavity of the convex head 5 is fixedly connected with a rubber gasket 13. The surface of the positioning bolt 7 is welded with a positioning hexagonal plate 14. By setting the positioning hexagonal plate 14, the positioning bolt 7 can be fixedly connected to the round hole at the top of the building body 1, so that the extreme position of the positioning bolt 7 can be limited, and the top of the positioning bolt 7 can be reserved with sufficient height to facilitate the subsequent connection of the convex head 5. The surface of the positioning bolt 7 is provided with threads 15. Example 2

[0025] Figure 1-5This invention illustrates a spray-coated thermal insulation roof according to an embodiment of the present invention, comprising: a wire mesh 2 disposed on the top of a building body 1; a positioning head 3 welded to the surface of the wire mesh 2, a threaded tube 4 rotatably connected to the inner cavity of the positioning head 3; a convex head 5 welded to the surface of the wire mesh 2; a circular hole opened in the top of the building body 1, a threaded bolt 6 threadedly connected to the inner cavity of the circular hole; a positioning bolt 7 fixedly connected to the inner cavity of the circular hole; the inner cavity of the convex head 5 slidably connected to the top of the positioning bolt 7; a semi-circular head 8 welded to the top of the positioning bolt 7; and two round rods slidably connected to the inner cavity of the convex head 5, with each of the two round rods 9 having a welded end to one of their opposite sides. A beveled head 10 is attached, and a spring 11 is welded between the beveled head 10 and the inner cavity of the convex head 5. The thread 15 is located below the positioning hexagonal plate 14. A limiting ring 16 is welded to the surface of the threaded tube 4. An annular groove is opened in the inner cavity of the positioning head 3, and the surface of the limiting ring 16 is rotatably connected to the inner cavity of the annular groove. A hexagonal head 17 is welded to the top of the threaded tube 4. By setting the hexagonal head 17, the friction between the operator's hand and the top of the threaded tube 4 can be increased when the operator is turning the threaded tube 4, making it easier to rotate the threaded tube 4 on the surface of the threaded plug 6.

[0026] Working Principle: In use, the user pre-fixes the positioning bolt 7 and the threaded tube 4 into the round holes opened on the top of the building body 1. Then, the convex head 5 is slidably connected to the surface of the positioning bolt 7. When the convex head 5 slides on top of the positioning bolt 7, the inclined head 10 inside the convex head 5 slides in opposite directions with its special shape and the cooperation of the semi-circular head 8. When the inclined head 10 slides below the semi-circular head 8, the rebound force of the spring 11 returns the inclined head 10 to its original position, thereby fixing the convex head 5 to the top of the positioning bolt 7, thus securing the wire mesh 2 to the building body 1. The force is applied to the positioning, and then the threaded tube 4, together with the positioning head 3, is slidably connected to the surface of the threaded bolt 6. Then, the hexagonal head 17 is turned to drive the threaded tube 4 to rotate in the inner cavity of the positioning head 3, thereby fixing the threaded tube 4 to the surface of the threaded bolt 6. This allows the wire mesh 2 to receive extended support on the top of the building body 1. Then, foam is sprayed onto the roof base layer, and the foam will cover the surface of the wire mesh 2, so that the foam sprayed onto the roof base layer can better adhere to the roof base layer, making the connection between the foam insulation layer and the roof base layer tighter.

[0027] In summary, this spray-coated thermal insulation roof, through the cooperation of the convex head 5 and the positioning bolt 7, and the positioning head 3 and the threaded bolt 6, can fix the wire mesh 2 to the top of the building body 1. Then, the foam is sprayed onto the roof base layer, and at the same time, the foam will cover the surface of the wire mesh 2. This achieves the purpose of making the foam sprayed onto the roof base layer better adhere to the roof base layer, so as to make the connection between the foam insulation layer and the roof base layer tighter.
