[0002] With the development of the construction industry, the requirements for the fire resistance and thermal insulation performance of building materials are increasing. Fire-resistant insulation boards are often used as exterior wall insulation components in building exterior wall insulation systems.

[0003] In existing technologies, the fire-resistant insulation boards used in traditional exterior walls generally employ insulation materials such as polystyrene (EPS) and polyurethane (PU), which, while possessing good insulation performance, have poor fire resistance. They are prone to combustion and release harmful gases in fires, seriously threatening the safety of buildings and failing to meet usage requirements. Therefore, it is particularly important to develop a composite insulation material that possesses both excellent insulation performance and effective fire resistance. To this end, an A-grade fire-resistant composite insulation board is proposed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 The image shows a Class A fireproof and heat-insulating composite board.

[0026] Example 1 includes a composite panel body 100 and a shaping frame 200. The two sides of the composite panel body 100 are parallel bevels. By setting the two sides of the composite panel body 100 as parallel bevels, the contact area when two adjacent composite panel bodies 100 are spliced ​​is larger, thus making the positioning of the two adjacent composite panel bodies 100 more accurate, and the mating surfaces between them tighter, resulting in higher airtightness. The composite panel body 100 includes at least a second fireproof insulation layer 104. The shaping frame 200 is disposed inside the composite panel body 100 and is used for shaping the composite panel body 100. The second fireproof insulation layer 104 is a B1-grade polystyrene board. Polystyrene board is used as the second fireproof insulation layer 104. The second fireproof insulation layer 104 is assembled to the middle of the shaped frame 200. The thickness of the second fireproof insulation layer 104 can be set according to specific usage requirements. However, the front and rear ends of the shaped frame 200 need to be exposed. Then, concrete mortar is sprayed on both sides of the second fireproof insulation layer 104. The concrete mortar is tightly wrapped with the shaped frame 200, so that the two sides of the second fireproof insulation layer 104 form two thin reinforced concrete plates. This makes the composite board body 100 have high strength, good stability, reasonable structure and controllable quality, providing good fireproof insulation for the building exterior wall.

[0027] The shaped frame 200 includes two wire mesh frames 201 and multiple trapezoidal frames 202. The two wire mesh frames 201 are arranged in parallel front and rear, and the multiple trapezoidal frames 202 are fixedly arranged horizontally between the front and rear wire mesh frames 201. By forming the shaped frame 200 with trapezoidal frames 202 and wire mesh frames 201, the multiple horizontally spaced trapezoidal frames 202 can be used to shape and support the second fireproof insulation layer 104, thereby enhancing the strength of the second fireproof insulation layer 104. In conjunction with the wire mesh frames 201 on the front and rear sides of the trapezoidal frames 202, the overall strength of the composite panel body 100 is higher, thus exhibiting high strength and crack resistance.

[0028] Example 2: Based on Example 1, the composite panel body 100 further includes two first fireproof and heat-insulating layers 101. The two first fireproof and heat-insulating layers 101 are respectively fixedly installed on the front and back sides of the second fireproof and heat-insulating layer 104. The first fireproof and heat-insulating layers 101 are Class A rock wool boards. By eliminating the need for sprayed concrete mortar on the front and back sides of the second fireproof and heat-insulating layer 104, and instead using two first fireproof and heat-insulating layers 101 assembled on the front and back sides of the second fireproof and heat-insulating layer 104, the high fire resistance of the first fireproof and heat-insulating layer 101 made of rock wool board and the high heat-insulating performance of the second fireproof and heat-insulating layer 104 can be utilized to make the composite panel body 100 have good fireproof and heat-insulating performance, thereby enhancing the fireproof and heat-insulating performance of the building exterior wall. At the same time, the composite panel body 100 is prefabricated, making the overall construction more convenient.

[0029] Furthermore, the composite panel body 100 also includes two sound insulation layers 102, which are fixedly disposed between the second fireproof insulation layer 104 and the first fireproof insulation layer 101, respectively. Both sides of the sound insulation layer 102 are provided with corrugated surfaces 103. The corrugated surfaces 103 not only increase the contact area and improve the bonding strength between the sound insulation layer 101 and the second fireproof insulation layer 104, but also enhance the noise reduction effect. By adding a sound insulation layer 102 between the first fireproof insulation layer 101 and the second fireproof insulation layer 104, and using existing sound insulation or sound absorption materials for the sound insulation layer 102, the finished composite panel body 100 can have a good noise reduction effect, improve the sound insulation and noise reduction performance of the building, and thus improve the quality of the composite panel body 100 as a building exterior wall panel.

[0030] Example 3: Based on Example 1 or Example 2, auxiliary pads 300 are fixedly embedded on both the front and back sides of the composite panel body 100. Four auxiliary pads 300 are located on the outer wall of the same side of the composite panel body 100 and are arranged in a rectangular array at intervals at the corners of the outer wall of the composite panel body 100. The side of the auxiliary pad 300 away from the composite panel body 100 is provided with an inwardly recessed auxiliary groove. The auxiliary groove is used to assist in the hoisting of the composite panel body 100. By arranging four auxiliary pads 300 in a rectangular array on the front and back of the composite panel body 100, and cooperating with the auxiliary groove on the auxiliary pad 300, the composite panel body 100 can be transported by using the auxiliary groove on the auxiliary pad 300 to cooperate with the hook of the hoisting equipment. This makes it convenient for the hook to be positioned with the composite panel body 100 through the auxiliary groove, thus facilitating the overall hoisting of the composite panel body 100 and improving the convenience of the assembly and transportation of the composite panel body 100.

[0031] The auxiliary groove includes a circular through hole 301 and a partially spherical through hole 302. The circular through hole 301 is located on the side of the auxiliary pad 300 away from the composite board body 100. The partially spherical through hole 302 communicates with the circular through hole 301 and extends inward to the auxiliary pad 300. The inner diameter of the partially spherical through hole 302 is larger than that of the circular through hole 301. By utilizing the partially spherical through hole 302 in the auxiliary groove, the depth of the auxiliary pad 300 at the position of the partially spherical through hole 302 is greater, thus creating a depth difference with the position of the circular through hole 301. This provides a limiting and locking position when the end of the hook extends into the partially spherical through hole 302. This design makes the positioning between the hook on the hoisting equipment and the auxiliary pad 300 more stable, which not only makes the positioning of the hook on the composite panel body 100 more convenient, but also improves the stability of the hoisting process. In addition, the auxiliary pad 300 and the auxiliary groove on it can also be used to connect two adjacent composite panel bodies 100 after they are spliced ​​together. The connection is achieved by using a connecting plate with two ball-head protrusions on one side. The ball-head protrusions are inserted into the incomplete spherical through hole 302 from the circular through hole 301 for positioning, thereby fixing the connecting plate to the composite panel body 100. This allows the two adjacent composite panel bodies 100 to be locked in place, enhancing the stability of the assembly between the two adjacent composite panel bodies 100.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
