Description

Technical Field

[0001] This utility model relates to the field of thermal insulation structure technology, specifically a composite prefabricated thermal insulation structure. Background Technology

[0002] Precast composite slab insulation structure usually refers to a precast component in which the insulation layer is tightly bonded to the structural layer of the composite slab through special processes and materials during the production of composite slabs, forming an integral whole.

[0003] The thermal insulation layer of the prefabricated composite slab insulation structure can effectively reduce heat transfer and improve the energy efficiency of the building. The thermal insulation layer is tightly bonded to the structural layer of the composite slab, which can improve the durability and service life of the components.

[0004] During the installation of precast composite insulation structures, seams inevitably exist between insulation boards. A significant amount of indoor heat is lost through these seams, reducing the insulation effect. Furthermore, rainwater may enter the insulation layer through gaps and holes at the seams. Once rainwater enters, it increases the humidity of the insulation material, increasing its thermal conductivity and reducing its insulation performance. Long-term water accumulation can also lead to mold and rot in the insulation material.

[0005] Therefore, a composite slab prefabricated thermal insulation structure is proposed to address the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated thermal insulation structure for composite panels to solve the problems that once rainwater enters, it will increase the humidity of the insulation material, increase its thermal conductivity, reduce its thermal insulation performance, and cause the insulation material to mold and rot if water accumulates for a long time.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A prefabricated composite slab insulation structure includes a protective layer for protecting the insulation material and structural layer, a structural layer for supporting the insulation material, and a connector for connecting the insulation material and structural layer. The structural layer is adhesively fixed to the inner side of the protective layer, and the connector is adhesively fixed to the inner side of the structural layer. An insulation board is fixedly fixed to the inner side of the connector, and a sealing device is fixedly connected to one side of the inclined edge of the insulation board. The insulation board includes a foam board, and a waterproof layer is adhesively fixed to the outer side of the foam board. The sealing device includes an installation block with an injection hole at its upper end, a connecting pipe fixedly connected to its lower end, a limit post fixedly connected to its lower end, and a sealing hole on the outer side of the limit post. Another protective layer has an installation groove on one side of its inclined edge, and another protective layer has a limit groove on one side of its inclined edge.

[0010] As a further optimization of this utility model, one end of both the foam board and the waterproof layer is set as an inclined plane, the center points of the foam board and the waterproof layer are located on the same vertical line, and the foam board and the waterproof layer are parallel to each other.

[0011] As a further optimization of this utility model, the mounting block and the mounting groove are respectively disposed on one side of the two inclined surfaces of the protective layer, the inner side of the mounting block is hollow, the mounting block and the mounting groove are interlocked with each other, and both the mounting block and the mounting groove are disposed at the upper end of the inclined surface of the protective layer.

[0012] As a further optimization of this utility model, the following features are provided: a plurality of connecting pipes and limiting posts are provided, and the connecting pipes and limiting posts are evenly and equidistantly distributed on one side of the inclined surface of the protective layer. The inner sides of the connecting pipes and limiting posts are hollow. The mounting block, connecting pipes and limiting posts are interconnected, and the inner side of the limiting posts is filled with sealant.

[0014] As a further optimization of this utility model, the cross-sectional shape of the limiting groove and the limiting post is semi-circular. The limiting grooves are evenly and equidistantly distributed on one side of the inclined surface of another protective layer. The limiting grooves are parallel to each other. The limiting post is installed inside the limiting groove by extrusion.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the sealant is squeezed out of the sealing hole and filled through the compression of the limiting post and the limiting groove, forming a highly efficient sealing structure. This effectively prevents rainwater and air from leaking out from the joint, ensuring the waterproof, moisture-proof, and airtight performance of the entire thermal insulation structure. It further protects the internal thermal insulation material. The waterproof layer prevents external moisture from penetrating into the foam board, avoiding a decrease in thermal insulation performance due to moisture, and also preventing moisture accumulation.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A prefabricated composite slab insulation structure includes a protective layer 1 for protecting the insulation material and structural layer 2, a structural layer 2 for supporting the insulation material, and a connector 3 for connecting the insulation material and structural layer 2. The structural layer 2 is fixedly connected to the inner side of the protective layer 1 by adhesive. The connector 3 is fixedly connected to the inner side of the structural layer 2 by adhesive.

The insulation board 4 includes a foam board 41. A waterproof layer 42 is fixedly connected to the outer side of the foam board 41 by adhesive. The sealing device 5 includes an installation block 51. An injection hole 52 is opened at the upper end of the installation block 51. A connecting pipe 53 is fixedly connected to the lower end of the installation block 51. A limit post 54 is fixedly connected to the lower end of the connecting pipe 53. A sealing hole 55 is opened on the outer side of the limit post 54. An installation groove 56 and a limit groove 57 are opened on one side of the inclined edge of another protective layer 1.

[0030] As a further implementation of the above technical solution: the protective layer 1, structural layer 2, connector 3 and thermal insulation board 4 are all set with one end as an inclined plane, the protective layer 1, structural layer 2, connector 3 and thermal insulation board 4 have the same shape, the upper ends of the protective layer 1, structural layer 2, connector 3 and thermal insulation board 4 are all set on the same horizontal plane, and the protective layer 1, structural layer 2, connector 3 and thermal insulation board 4 are parallel to each other. This arrangement can achieve a tight connection of components, reduce the generation of gaps, and thus improve the integrity of the entire thermal insulation structure.

[0031] As a further implementation of the above technical solution: the limiting groove 57 and the limiting post 54 are semi-circular in cross-section. The limiting groove 57 are evenly and equidistantly distributed on one side of the inclined surface of the other protective layer 1. The limiting grooves 57 are parallel to each other. The limiting post 54 is installed inside the limiting groove 57 by extrusion. The limiting groove 57 and the limiting post 54 can achieve precise splicing and stable connection of the two protective layers 1 through extrusion, thereby enhancing the sealing effect.

[0032] As a further implementation of the above technical solution: one end of both the foam board 41 and the waterproof layer 42 is set as an inclined surface, the center points of the foam board 41 and the waterproof layer 42 are located on the same vertical line, the foam board 41 and the waterproof layer 42 are parallel to each other, the foam board 41 provides thermal insulation performance, and the waterproof layer 42 prevents moisture from penetrating into the foam board 41. The two work together to maintain the thermal insulation effect and extend the service life of the thermal insulation board 4.

[0033] As a further implementation of the above technical solution: a number of connecting pipes 53 and limiting posts 54 are provided. The connecting pipes 53 and limiting posts 54 are evenly and equidistantly distributed on one side of the inclined surface of the protective layer 1. The inner side of the connecting pipes 53 and limiting posts 54 is hollow. The mounting block 51, the connecting pipes 53 and the limiting posts 54 are connected. The inner side of the limiting posts 54 is filled with sealant. The connecting pipes 53 and the limiting posts 54 cooperate with each other, so that the sealant can effectively fill the gaps when the protective layer 1 is spliced, thereby enhancing the sealing performance.

[0034] As a further implementation of the above technical solution: a number of sealing holes 55 are provided. The vertical cross-section of the sealing holes 55 is trapezoidal. The sealing holes 55 are symmetrically arranged with the vertical line of the limiting post 54 as the axis. The sealing holes 55 are evenly and equidistantly distributed on the outside of the limiting post 54. The sealing holes 55 are parallel to each other. When the limiting post 54 is squeezed, the sealing hole 55 can make the sealant evenly squeezed out to fill the splicing gap and enhance the sealing effect of the splicing of the protective layer 1.

[0035] As a further implementation of the above technical solution: the mounting block 51 and the mounting groove 56 are respectively set on one side of the slope of the two protective layers 1. The inner side of the mounting block 51 is hollow. The mounting block 51 and the mounting groove 56 are interlocked with each other. The mounting block 51 and the mounting groove 56 are both set at the upper end of the slope of the protective layer 1. The interlocking of the mounting block 51 and the mounting groove 56 provides preliminary positioning and stable connection for the splicing of the two protective layers 1, which helps to ensure the sealing effect.

[0036] Workflow: First, the protective layer 1, structural layer 2, connector 3, and thermal insulation board 4 are fixedly connected by adhesive. Then, another protective layer 1 with mounting groove 56 and limiting groove 57 is prepared. Sealant is then injected through injection hole 52 into mounting block 51, connecting pipe 53, and limiting post 54, filling the inside of limiting post 54 with sealant. Next, the protective layer 1 with sealing device 5 is spliced ​​with the protective layer 1 with mounting groove 56 and limiting groove 57. When the two protective layers 1 are spliced, the mounting block 51 in sealing device 5 interacts with the mounting groove 56 on the other protective layer 1. The inner side of mounting block 51 is hollow, and the outer side of mounting block 51 and the inner side of mounting groove 56 interlock, both located on the inclined surface of protective layer 1. At the upper end, this process initially determines the splicing position of the two protective layers 1. The limiting post 54 is installed inside the limiting groove 57 by extrusion, so that the two protective layers 1 are further fixed and positioned in the splicing direction. During the process of the limiting post 54 being extruded into the limiting groove 57, the sealant is squeezed and squeezed out through the sealing hole 55 on the outside of the limiting post 54. The squeezed sealant fills the gap between the limiting post 54 and the limiting groove 57, the gap between the mounting block 51 and the mounting groove 56, and other small gaps in the splicing surface of the two protective layers 1, thereby completing the splicing and sealing of the two protective layers 1, realizing the assembly of the entire composite slab prefabricated thermal insulation structure, effectively ensuring the sealing between the thermal insulation structures, and preventing the insulation material from becoming moldy and rotting.
