Description

Technical Field

[0001] This application belongs to the technical field of thermal engineering, and particularly relates to a double-wing folding plate fixing structure applicable to a light furnace wall. Background Art

[0002] In the field of boiler engineering design and construction, the thermal insulation design of boilers and its implementation effect are directly related to the overall thermal efficiency and operation economy of the boiler system, especially playing a crucial role in controlling heat loss and maintaining good sealing performance. With the continuous growth of the demand for boiler capacity in modern industry, the complexity of the boiler thermal insulation structure has also increased accordingly. Especially when dealing with large boilers, the on-site workload of thermal insulation design nodes has increased significantly, posing more severe challenges to construction efficiency and cost control.

[0003] In order to achieve efficient thermal insulation and take into account the aesthetics of the boiler appearance, the common practice is to lay color steel plates outside the thermal insulation layer. This measure can not only effectively resist the erosion of the external environment on the thermal insulation material but also significantly improve the overall visual texture of the boiler. However, in traditional design schemes, the furnace wall thermal insulation nails are mainly fixed to the wire mesh laid on the surface of the furnace wall through a layer of self-locking pressure plate. Although this fixing method is stable, when fixing the color steel plate subsequently, it is often necessary to additionally install stay plates, connecting flat steels or use complex angle steel ring structures, which not only increases the material cost but also makes the construction process cumbersome and prolongs the project cycle.

[0004] In view of the above background, there are urgent problems to be solved in the current boiler thermal insulation design and construction, that is, how to design an innovative thermal insulation and color steel plate fixing structure to effectively reduce material consumption, simplify on-site installation steps while ensuring thermal insulation effect and appearance aesthetics, thereby significantly reducing production costs and shortening the construction cycle.

[0028] Among them, the double-wing folding plate 1 includes an upper wing plate 11, a web 12, and a lower wing plate 13. The double-wing folding plate 1 is bent from a steel plate and integrally formed.

[0029] The double-wing folding plate 1 is used to connect the color steel plate 5 on the outer side of the furnace wall and can also fixedly install the thermal insulation nail 2 of the furnace wall. The double-wing folding plate 1 is connected to the color steel plate 5 on the outer side of the wall with self-drilling screws 4 and is connected to the thermal insulation nail 2 of the furnace wall with a double-layer self-locking pressure plate 3.

[0030] Specifically, in the order from inside the furnace to outside the furnace, one end of the insulating nail 2 is welded to the inner steel plate 6 of the furnace wall, and it sequentially passes through the thermal insulation material, the inner pressing plate of the double-layer self-locking pressing plate 3, the web 12 of the double-wing folding plate 1, and the outer pressing plate of the double-layer self-locking pressing plate 3. The inner pressing plate of the double-layer self-locking pressing plate 3 and the insulating nail 2 are used to compact the thermal insulation material inside the furnace wall, and the insulating nail 2 provides support for the double-wing folding plate 1. The inner pressing plate of the double-layer self-locking pressing plate 3, the outer pressing plate of the double-layer self-locking pressing plate 3 and the insulating nail 2 cooperate with each other to firmly fix the web 12 of the double-wing folding plate 1 and increase the rigidity of the double-wing folding plate 1 at the same time.

[0031] It should be noted that the web 12 is bent towards the inside of the furnace to provide space for laying the color steel plate 5 and leave a construction position for the connection of the wing plates (upper wing plate 11, lower wing plate 13) and the color steel plate 5. Specifically, during on-site construction, the color steel plate 5 can be fixed to the upper wing plate 11 and the lower wing plate 13 of the double-wing folding plate 1 at the trough position with self-locking screws 4. Through the connection function of the double-wing folding plate 1 and the strengthening function of the insulating nail 2, the outer wall color steel plate 5 can be laid and fixed while fixing the thermal insulation material, thus saving production and manufacturing costs, simplifying the construction at the construction site, and shortening the construction period.

[0032] As an example, please refer to Figure 2 As shown, the pitch of the arrangement of the insulating nails 2 is about 300 - 400 mm, which plays a role in fixing and strengthening the double-wing folding plate 1.

[0033] In summary, a double-wing folding plate fixing structure applicable to a light furnace wall provided by an embodiment of the present application can compact the thermal insulation material by using the inner pressing plate of the double-layer self-locking pressing plate 3 and the insulating nail 2. The double-layer self-locking pressing plate 3 and the insulating nail 2 can connect the double-wing folding plate 1 and the insulating nail 2, and then the self-locking screw 4 is used to fix the laid color steel plate 5 on the double-wing folding plate 1. This structure can utilize the supporting functions of the insulating nail 2 and the double-layer self-locking pressing plate 3 to fix the outer wall color steel plate 5 while fixing the insulating nail 2 and pressing the thermal insulation material tightly, without the need to additionally arrange bracing plates and connecting flat steels for fixing the color steel plate 5. Therefore, it can save costs, is convenient for construction, and the double-wing folding plate 1 is integrally bent from a steel plate, and the integral forming manufacturing process is simple.
