Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite integrated panel technology, and more specifically, to a polyurethane cast composite integrated panel. Background Technology
[0002] The main material of polyurethane cast composite panels is polyurethane foam, a material with low thermal conductivity that effectively reduces heat transfer. Furthermore, these panels are lightweight, high-strength, environmentally friendly, energy-saving, and easy to install, making them widely applicable in the construction industry.
[0003] Existing composite panels are usually bonded to each layer only with adhesive, which requires manual application. However, manual application can result in uneven application, with some areas having too much adhesive and others not being bonded at all. This leads to poor bonding and shortens the lifespan of the composite panel. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a polyurethane cast composite integrated panel, which aims to improve the existing composite integrated panels that are usually only bonded to each layer with adhesive, which requires manual application. However, manual application can result in uneven application, with some areas having too much adhesive and others not being bonded, leading to poor bonding and shortening the service life of the composite integrated panel.
[0005] This utility model is implemented as follows:
[0006] This application provides a polyurethane cast composite integrated panel including a composite integrated panel connecting assembly.
[0007] The composite integrated panel connecting assembly includes a base plate, a first receiving groove, a protrusion, a sealing plate, a groove, a waterproof layer, a second receiving groove, and a polyurethane casting layer. The first receiving groove is formed on the top of the base plate. Multiple protrusions are provided in the first receiving groove. The sealing plate is provided in the first receiving groove. The bottom of the first receiving groove is formed with a groove corresponding to the protrusion. The waterproof layer is provided in the second receiving groove on the top of the sealing plate. The polyurethane casting layer is provided on top of the waterproof layer.
[0008] In a preferred embodiment of this utility model, a connecting column is fixedly provided inside the second receiving groove, and multiple connecting columns are provided.
[0009] In a preferred embodiment of this utility model, the bottom of the waterproof layer is provided with connecting holes, and the number and position of the connecting holes correspond to the connecting posts.
[0010] In a preferred embodiment of this utility model, the top of the waterproof layer is further provided with a T-shaped groove, and multiple T-shaped grooves are provided.
[0011] In a preferred embodiment of this utility model, the bottom of the polyurethane casting layer matches the T-groove.
[0012] In a preferred embodiment of this utility model, a top sealing frame is provided on the top of the polyurethane casting layer.
[0013] In a preferred embodiment of this utility model, both the top sealing frame and the bottom plate are provided with perforations on their periphery, and through nails are provided inside the perforations.
[0014] In a preferred embodiment of this utility model, a decorative panel is fixedly adhered to the top of the top sealing frame.
[0015] Beneficial Effects: This utility model proposes a polyurethane cast composite integrated panel. During assembly, environmentally friendly adhesive is first poured into the first receiving groove, ensuring even distribution. Then, the groove on the bottom of the sealing plate is aligned with the protrusion and pressed down, bonding the sealing plate to the base plate. The protrusion and groove reinforce the connection. Next, the waterproof layer is bonded to the sealing plate in the same way. The first and second receiving grooves eliminate the need for manual application, ensuring a strong connection between the panels. Polyurethane is then poured onto the waterproof layer, completely filling the T-grooves and further strengthening the composite panel. Finally, the top sealing frame is fixed to the base plate with through-bolts, encasing the entire composite panel and extending its service life. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Please see Figures 1-5 This utility model provides a technical solution: a polyurethane cast composite integrated panel includes a composite integrated panel connecting component 100. The composite integrated panel connecting component 100 improves upon the existing composite integrated panel method, which typically uses adhesive to bond each layer, requiring manual application. However, manual application can result in uneven application, with some areas having excessive adhesive while others are poorly bonded, leading to inadequate bonding and a shortened lifespan of the composite integrated panel.
[0025] Please see Figures 1-5 The composite integrated panel connecting assembly 100 includes a base plate 110, a first receiving groove 120, a protrusion 130, a sealing plate 140, a groove 150, a waterproof layer 160, a second receiving groove 170, and a polyurethane casting layer 180. The base plate 110 has a first receiving groove 120 on its upper surface. Multiple protrusions 130 are disposed within the first receiving groove 120. The sealing plate 140 is disposed within the first receiving groove 120. A groove 150 corresponding to the protrusion 130 is formed at the bottom of the first receiving groove 120.
[0026] Please see Figures 1-5A waterproof layer 160 is disposed within a second receiving groove 170 at the top of the sealing plate 140. Multiple connecting columns 171 are fixedly disposed inside the second receiving groove 170. A polyurethane casting layer 180 is disposed on top of the waterproof layer 160. Connecting holes 161 are provided at the bottom of the waterproof layer 160, with the number and position of the connecting holes corresponding to the connecting columns 171. A T-slot 162 is also provided at the top of the waterproof layer 160, with multiple T-slots 162. The bottom of the polyurethane casting layer 180 matches the T-slot 162.
[0027] Please see Figures 1-5 A top sealing frame 181 is provided on the top of the polyurethane casting layer 180. Perforations 111 are provided on the periphery of both the top sealing frame 181 and the base plate 110. Through nails 112 are provided inside the perforations 111. A decorative panel 182 is fixedly adhered to the top of the top sealing frame 181. The decorative panel 182 serves to beautify the environment.
[0028] Working Principle: This utility model proposes a polyurethane cast composite integrated panel. During assembly, firstly, environmentally friendly adhesive is poured into the first receiving groove 120, ensuring even distribution. Then, the groove 150 at the bottom of the sealing plate 140 is aligned with the protrusion 130 and pressed down, bonding the sealing plate 140 to the base plate 110. The protrusion 130 and groove 150 reinforce the connection. Next, the waterproof layer 160 is bonded to the sealing plate 140 in the same manner. The first and second receiving grooves 120 and 170 eliminate the need for manual application, ensuring a strong connection between the panels. Polyurethane is then poured onto the waterproof layer 160, completely filling the T-groove 162 and further strengthening the composite panel. Finally, the top sealing frame 181 is fixed to the base plate 110 using through nails 112, encapsulating the entire composite panel and extending its service life.
[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
