Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials technology, and in particular to a composite heat-insulating and fireproof insulation board. Background Technology
[0002] Composite thermal insulation and fireproof panels are widely used in building exterior walls, industrial plants, cold storage facilities, and other places, offering excellent thermal insulation, heat preservation, and fire resistance. These panels are typically composed of multiple functional materials, and through a rational structural design, they achieve high thermal resistance, superior fire resistance, and stable structural strength. While ensuring the energy efficiency of buildings, they also improve the overall safety level and service life, meeting the comprehensive requirements of modern buildings for energy conservation, environmental protection, and fire resistance.
[0003] Currently, common composite thermal insulation and fireproof insulation boards typically employ a multi-layered composite structure. The core insulation layer consists of materials such as polyurethane, phenolic foam, rock wool, and glass wool, while the outer layer is combined with structural materials such as cement substrate, metal plate, or inorganic board, and integrally formed through bonding or mechanical bonding. These boards possess excellent thermal insulation, fire resistance, and mechanical properties, and are widely used in energy-saving and fire-resistant systems for industrial buildings, public facilities, and residential exterior walls. However, in actual installation, traditional insulation boards mostly rely on bonding, bolting, or simple butt joints for connection, resulting in low splicing efficiency, significant susceptibility to manual installation accuracy, and difficulty in achieving reliable sealing at the joints. Therefore, a composite thermal insulation and fireproof insulation board is proposed to address these issues. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a composite heat-insulating and fireproof insulation board, which aims to improve the problem that the connection methods of traditional insulation boards in the prior art mostly rely on bonding, bolt fixing or simple butt joint methods, resulting in low splicing efficiency and installation accuracy being greatly affected by manual labor.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A composite heat-insulating and fireproof insulation board, comprising,
[0007] A baseboard is disposed in the middle of the insulation board;
[0008] A heat-insulating core layer is disposed above the base plate;
[0009] A covering layer is disposed below the base plate;
[0010] The slot and the tongue are respectively provided on opposite sides of the insulation board;
[0011] A sealing strip is provided between the slot and the tongue to seal the connection.
[0012] As a further description of the above technical solution:
[0013] The heat insulation core layer is made of foamed ceramic material.
[0014] As a further description of the above technical solution:
[0015] The cladding layer is made of metal sheet.

[0020] As a further description of the above technical solution:
[0021] The base plate, the heat insulation core layer, and the cover layer are connected by a high-temperature adhesive.
[0022] This utility model has the following beneficial effects:
[0023] In this invention, the cooperation between the latch and the slot allows adjacent insulation boards to be quickly assembled, simplifying the installation process and improving construction efficiency. At the same time, a silicone sealing strip is embedded between the slot and the latch. During the installation process, the sealing strip is pressed simultaneously to fill the gaps between the boards, effectively improving the airtightness of the joint, preventing air and moisture penetration, further enhancing the fire resistance of the connection, and preventing flames or high-temperature gases from spreading along the joint.

[0029] 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.
[0030] Reference Figures 1-3 This utility model provides an embodiment of a composite heat-insulating and fire-resistant insulation board, comprising: a base plate 1, disposed in the middle of the insulation board, used to provide mechanical support and stability for the overall structure, ensuring the shape retention of the board during long-term use; a heat-insulating core layer 2, disposed above the base plate 1, the heat-insulating core layer 2 being made of foamed ceramic material, possessing excellent thermal insulation and high-temperature resistance, effectively blocking heat conduction, and also possessing certain fire-resistant properties, which can delay the spread of fire in a fire; a facing layer 3, disposed below the base plate 1, the facing layer 3 being made of metal plate, enhancing the impact resistance and protection of the overall structure, while improving the durability of the insulation board; a slot 4 and a latch. 5. The latches 5 are respectively set on opposite sides of the insulation board. The latches 5 are inserted into the slots 4 on the adjacent insulation board. Through the cooperation between the latches 5 and the slots 4, the effect of quick installation and stable splicing is achieved, which improves construction efficiency and reduces thermal bridging. The sealing strip 6 is set between the slots 4 and the latches 5 to seal the connection. The sealing strip 6 is made of silicone material and has excellent high temperature resistance and aging resistance. It can prevent air penetration and moisture ingress, effectively improving the airtightness and fire resistance of the board connection. The base board 1, the heat insulation core layer 2 and the cover layer 3 are connected by high temperature adhesive to ensure that the functional layers are firmly bonded and maintain the stability and functional integrity of the overall structure in high temperature environment.
[0031] Working principle: When laying the insulation boards, the tongue of one insulation board is inserted into the groove 4 of the adjacent board to lock them together. This plug-in method simplifies the installation process, improves construction efficiency, and ensures a tight fit between the boards, reducing gaps. A silicone sealing strip 6 is embedded between the groove 4 and the tongue 5. During the locking process, the sealing strip 6 is pressed simultaneously to fill the joint gap. This method improves the airtightness of the joint, preventing air and moisture penetration, and also enhances the fire resistance of the connection area, preventing the spread of flames or heat through the joint. During installation, the base board 1 provides overall mechanical support to prevent board deformation. The insulation core layer 2 faces upward to block heat conduction and insulate against high temperatures. The top layer 3 faces downward to improve impact resistance and durability. Through the cooperation of these three components, the system remains stable and does not easily delaminate under high temperature or fire conditions.
[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.
