Description

Technical Field

[0001] This utility model relates to the field of thermal insulation technology, specifically to a low-energy composite thermal insulation board. Background Technology

[0002] Insulation boards, simply put, are boards used for insulating buildings. They are rigid foam plastic boards made from polystyrene as the main raw material, along with other raw materials and polymers. The mixture is heated and mixed while a catalyst is injected, and then extruded and molded. They are commonly used in the construction industry and have thermal insulation, moisture-proof, and sound-insulating properties.

[0003] In existing technologies, 1. Vacuum insulation boards are used directly as insulation boards, but the breakage rate is extremely high; 2. Vacuum boards are combined with insulation slurry protective layers, which reduces the breakage rate, but the insulation effects of the two materials are very different, and cold bridging is prone to occur. The design correction coefficient is large, and the overall performance is poor, which limits the application of the product; 3. Traditional extruded polystyrene boards are difficult to meet increasingly higher energy-saving requirements when used alone. Utility Model Content

[0004] To address the problems existing in the prior art, a low-energy composite insulation board is provided. This device utilizes extruded polystyrene board as the base plate, which greatly reduces cold bridges and increases the overall strength of the insulation board. The vacuum insulation board as the core material significantly improves the insulation performance. The application of insulation mortar not only enhances the overall performance of the insulation material but also effectively protects the vacuum insulation board.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] This utility model proposes a low-energy composite insulation board, including an extruded polystyrene board, a vacuum insulation board attached to one side of the extruded polystyrene board, and an insulation mortar attached to the periphery of the vacuum insulation board; the vacuum insulation board is located between the extruded polystyrene board and the insulation mortar, and the insulation mortar wraps around the vacuum insulation board to isolate the vacuum insulation board from the outside world.

[0007] Preferably, the extruded polystyrene board and the thermal insulation slurry are staggered.

[0008] Preferably, one end of the extruded polystyrene board has an inwardly recessed portion, and the other end of the extruded polystyrene board has an outwardly protruding portion that fits into the adjacent recessed portion.

[0009] Preferably, a multi-vacuum insulation board is laminated to a single extruded polystyrene board as the substrate, with gaps between adjacent vacuum insulation boards filled with insulating slurry.

[0010] Preferably, a plurality of connecting frames are provided in the gap, and the two sides of the connecting frames are respectively connected to two adjacent vacuum insulation panels.

[0011] Preferably, it also includes a connector that can be inserted into the pre-embedded hole in the extruded polystyrene board, wherein the connector has a through hole for the tie bolt to pass through.

[0012] Preferably, a pair of retaining plates are provided on each side of the connector, and the two pairs of retaining plates are symmetrically arranged along the connector. The pair of retaining plates and the connector form a vacuum plate retaining groove into which the vacuum insulation panel is embedded.

[0013] Preferably, the thermal insulation mortar is embedded with a wire mesh, and the connector has a wire slot that can engage the wire mesh.

[0014] Preferably, the connector is connected to a support plate that can fit the extruded polystyrene board, and the support plate and the connector are threaded together.

[0015] Preferably, a decorative layer is attached to the outer side of the thermal insulation mortar.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model combines extruded polystyrene board with vacuum insulation board, which greatly improves the thermal insulation effect of the materials. The thermal insulation mortar on the outside not only improves the overall performance of the insulation board, but also protects the vacuum insulation board.

Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] Example 1

[0036] like Figures 1-8As shown, this embodiment proposes a low-energy composite insulation board, including an extruded polystyrene board 2, a vacuum insulation board 3 attached to one side of the extruded polystyrene board 2, the extruded polystyrene board 2 being bonded to the vacuum insulation board 3 through an adhesive layer 21, and an insulation slurry 1 being attached to the periphery of the vacuum insulation board 3. The extruded polystyrene board 2 can be replaced with polystyrene board, PU board, or other insulation materials.

[0037] Vacuum insulation board 3 and extruded polystyrene board 2 can be combined with insulation mortar 1 by pouring, bonding or other methods. Vacuum insulation board 3 is located between extruded polystyrene board 2 and insulation mortar 1. Insulation mortar 1 wraps around vacuum insulation board 3, thereby isolating vacuum insulation board 3 from the outside world.

[0038] Using extruded polystyrene board 2 as the core material and vacuum insulation board 3 as the core material greatly improves the thermal insulation effect of the material. The thermal insulation mortar 1 set on the outside improves the overall performance of the thermal insulation material and also protects the vacuum insulation board 3 well. Using extruded polystyrene board 2 with good thermal insulation effect as the base plate greatly reduces the cold bridge effect and improves the overall thermal insulation performance.

[0039] The extruded polystyrene board 2 and the thermal insulation mortar 1 are staggered. One end of the extruded polystyrene board 2 forms an inward recess, and the other end of the extruded polystyrene board 2 forms an outward protrusion that fits into the adjacent recess. This enables the fitting between two adjacent low-energy composite insulation boards and the assembly of adjacent low-energy composite insulation boards. Using this method, adjacent low-energy composite insulation boards can be aligned to form a complete thermal insulation wall.

[0040] Or such as Figure 3 As shown, Figure 3 This is a top view of the entire utility model. Figure 3 Both ends of the thermal insulation mortar 1 and the extruded polystyrene board 2 are beveled. During assembly, the beveled sides fit together, which enables better cooperation between the two low-energy composite insulation boards.

[0041] A single extruded polystyrene board 2 serves as the substrate, on which several vacuum insulation boards 3 are bonded. Gaps are provided between adjacent vacuum insulation boards 3, and these gaps are filled with thermal insulation mortar 1. The thermal insulation mortar 1 encapsulates the several vacuum insulation boards 3, thereby better protecting the vacuum insulation boards 3. The thermal insulation mortar 1 is made of a special non-combustible material.

[0042] The outer side of the thermal insulation mortar 1 is covered with a decorative layer 10, which can be aluminum single panel, ceramic thin panel, rock slab, real stone paint, etc. The decorative layer 10 also has the function of thermal insulation. The decorative layer 10 is formed in one piece, which can save construction time and solve the problem of the difficulty in realizing the diversity of building facades.

[0043] Several connecting frames 4 are provided in the gap. The two sides of the connecting frame 4 are connected to two adjacent vacuum insulation panels 3 respectively. The connecting frame 4 includes several connecting ribs 41. The connecting frame 4 has a hollow structure. The connecting ribs 41 are used to connect the entire connecting frame 4, reducing the overall weight of the connecting frame 4 and making it easier to process and install. The connecting frame 4 is an optional structure and can be installed according to actual needs.

[0044] By using extruded polystyrene board 2 as the back panel and vacuum insulation board 1 as the core material, the thermal insulation effect of the board is greatly improved, the cold bridge is reduced, and the energy-saving design correction coefficient can be greatly reduced from the traditional 1.25-1.5 to 1.05-1.15.

[0045] In terms of overall integrity, traditional slurry-coated vacuum boards are discontinuous blocks that rely solely on the slurry coating for strength, resulting in poor overall integrity and a flexural strength that barely meets current national standards. In contrast, this application utilizes the inherent superior overall shape of the extruded polystyrene board 2, combined with an outer protective layer, to achieve better overall integrity of the board, with the overall flexural strength exceeding current standards by more than 50%.

[0046] In addition, the thickness of the outer thermal insulation mortar 1 is 20-30mm, the thickness of the extruded polystyrene board 2 is 30-50mm, and the thickness of the vacuum insulation board 3 is designed according to energy-saving design requirements. It can meet the design and construction requirements of various conventional building projects, low-energy consumption projects, passive house projects, low-carbon, near-zero-carbon, and zero-carbon building projects, as well as special needs projects in extremely cold and extremely hot regions.

[0047] Example 2

[0048] Reference Appendix Figures 9-12 In this embodiment, the connecting frame is replaced by the connecting piece 5, which also includes the connecting piece 5 that can be inserted into the pre-embedded hole of the extruded polystyrene board 2. The connecting piece 5 has a through hole 52 for the tie bolt 9 or other tie member to pass through. Since the connecting piece 5 can be inserted into the pre-embedded hole of the extruded polystyrene board 2, the connection between the extruded polystyrene board 2 and the vacuum insulation board 3 can be realized by using the connecting piece 5, without the need for subsequent additional opening, which facilitates subsequent assembly and molding.

[0049] A pair of clamping plates 6 are provided on each side of the connector 5. The two pairs of clamping plates 6 are symmetrically arranged along the connector 5. The pair of clamping plates 6 and the connector 5 form a vacuum plate slot 61 into which the vacuum insulation panel 3 is embedded. A connector 5 is provided with a total of four clamping plates 6. The clamping plates 6 and the connector 5 can be integrally cast to achieve the connection of the vacuum insulation panels 3 on both sides.

[0050] The insulation mortar 1 is embedded with a wire mesh 8, and the connector 5 has a wire slot 51 that can engage the wire mesh 8. The wire mesh 8 can be replaced with galvanized welded wire mesh or mesh cloth, thereby strengthening the overall strength of the insulation mortar 1 and increasing its overall flexural strength. One side of the connector 5 protrudes outward and can be anchored into the concrete, so that the insulation board can play a certain role in protection and connection when used as an outer formwork.

[0051] The connector 5 is connected to a support plate 7 that can fit the extruded polystyrene board 2. The support plate 7 has an internal thread 71 on its inner side, and the connector 5 has an external thread 53 on its outer side through threading, so as to realize the threaded connection between the support plate 7 and the connector 5. The cross-section of the support plate 7 is circular or polygonal, and the support plate 7 supports the extruded polystyrene board 2.

[0052] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
