Description

Technical Field

[0001] This utility model relates to the field of extruded polystyrene (XPS) board technology, specifically to a splicing XPS board for green building. Background Technology

[0002] In the construction industry, with the global emphasis on energy conservation, emission reduction, and sustainable development, the concept of green building is gradually gaining popularity. Building insulation, as a crucial link in achieving building energy conservation, relies heavily on innovation in materials and construction technologies. Traditional building insulation materials, such as polystyrene foam boards, have advantages such as high strength, low water absorption, and good thermal insulation performance, and are widely used in the field of building insulation. However, while extruded polystyrene boards have certain advantages in insulation performance, they also have many limitations in practical applications. For example, these materials are usually used in whole blocks, which are large in size and easily damaged by collisions and compression during transportation and installation, increasing material waste and prolonging the construction period. Furthermore, whole-block insulation materials are difficult to adjust flexibly and install precisely when dealing with complex building structures, easily resulting in gaps, reduced insulation effectiveness, and affecting the overall aesthetics of the building. Utility Model Content

[0004] This utility model provides a splicing extruded polystyrene board for green buildings, which solves the problems of traditional extruded polystyrene boards being easily damaged by collisions during transportation and installation, and the difficulty in accurately positioning and installing traditional extruded polystyrene boards during splicing.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a splicing extruded polystyrene (XPS) board for green building, comprising several sets of XPS board units, with two or four adjacent sets of XPS board units being fixedly connected by connectors, and the several sets of XPS board units being laid flat on the same plane. Each XPS board unit includes an XPS pad layer, two outer frames, and two locking blocks. The two outer frames are symmetrically distributed and are respectively inserted into the outer side of the XPS pad layer from opposite sides. Locking blocks are inserted and fixedly connected to the joints of two adjacent outer frames, so that the two outer frames cover and fix the outer wall of the XPS pad layer.

[0007] Preferably, the outer frame includes a U-shaped frame, a positioning strip, two combined grooves, and two positioning grooves. The positioning strip is formed at the center of the inner sidewall of the U-shaped frame and is used to connect with the extruded pad layer. The two combined grooves are formed on the two end faces of the U-shaped frame and are used to engage with the locking block for secure connection. The two positioning grooves are formed on the two end corners of the U-shaped frame and are used to engage with the locking connection of the connector.

[0008] In a further preferred embodiment, the extruded pad layer is configured as a rigid foam plastic board formed by extrusion. The extruded pad layer includes an upper pad layer, a lower pad layer, and a middle pad layer. The lower pad layer is disposed between the upper pad layer and the middle pad layer, and the lower pad layer is fixedly connected to both the upper pad layer and the middle pad layer. Grooves that cooperate with positioning strips are formed between the lower pad layer, the upper pad layer, and the middle pad layer.

[0009] In a further preferred embodiment, the connector includes a double positioning block, wherein two adjacent sets of the outer frames are connected by the double positioning block, and the double positioning block is inserted into and secured to the adjacent positioning slots in the two sets of outer frames.

[0011] (III) Beneficial Effects

[0012] Compared with the prior art, this utility model provides a spliced ​​extruded polystyrene board for green building, which has the following beneficial effects:

[0013] The assembly design of the outer frame and locking blocks in the extruded polystyrene (XPS) board unit not only enhances the structural strength of the XPS board unit but also provides excellent protection for the XPS padding layer, reducing the impact of external environmental factors on the XPS padding layer and minimizing collision damage during transportation. Furthermore, by using connectors between two or four adjacent XPS board units for positioning and securing, several XPS board units can be laid out flat on the same plane. This connection method effectively enhances the connection strength between XPS board units, ensuring the overall stability of the assembled XPS board structure and preventing loosening or displacement. Simultaneously, locking blocks are inserted at the joints of adjacent outer frames for secure connection, allowing the two outer frames to tightly cover and fix the outer wall of the XPS padding layer, further reducing the formation of splicing gaps, effectively preventing heat transfer, and thus improving the thermal insulation performance of the XPS board.

Detailed Implementation

[0019] 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.

[0020] Example 1

[0021] Please see Figures 1 to 3 A type of interlocking extruded polystyrene board for green building includes several sets of extruded polystyrene board units. Adjacent sets are fixedly connected by a double positioning block 40, and the sets of extruded polystyrene board units are laid flat on the same plane.

[0022] In this embodiment, the extruded polystyrene (XPS) board unit includes an XPS pad 10, two outer frames 20, and two locking blocks 30. The two outer frames 20 are symmetrically distributed and are inserted into the outer side of the XPS pad 10 from opposite sides. Locking blocks 30 are inserted and secured to the joints of two adjacent outer frames 20, thus fixing the two outer frames 20 to cover the outer wall of the XPS pad 10. The two outer frames 20 and the two locking blocks 30 are pre-assembled on the outer side of the XPS pad 10, and the two outer frames 20 serve to cover and protect the XPS pad 10.

[0023] In this embodiment, the extruded padding layer 10 includes an upper padding layer 11, a lower padding layer 12, and a middle padding layer 13. The lower padding layer 12 is disposed between the upper padding layer 11 and the middle padding layer 13, and is fixedly connected to both the upper padding layer 11 and the middle padding layer 13. Grooves are formed between the lower padding layer 12 and the upper padding layer 11 and the middle padding layer 13 to engage with the outer frame 20. The extruded padding layer 10 can be made entirely of extruded rigid foam plastic board.

[0024] In this embodiment, the outer frame 20 includes a U-shaped frame 21, a positioning strip 22, two combination grooves 23, and two positioning grooves 24. The positioning strip 22 is formed at the center of the inner sidewall of the U-shaped frame 21 and is used to connect with the extruded pad 10. That is, during the assembly of the outer frame 20, the positioning strip 22 on the inner side of the U-shaped frame 21 can be inserted into the groove between the lower pad 12 and the upper pad 11 and the middle pad 13, and the assembly is completed after the U-shaped frame 21 abuts against the extruded pad 10. The two combination grooves 23 are respectively formed on the two end faces of the U-shaped frame 21. The shape of the gap between adjacent combination grooves 23 on the two U-shaped frames 21 is adapted to the shape of the locking block 30, so that the combination groove 23 can be used to engage with the locking block 30 to lock together, completing the installation of the outer frame 20 on the outside of the extruded pad 10.

[0025] In this embodiment, the shape of the double positioning block 40 used in the connector is the same as the gap shape of the combination between the adjacent positioning slots 24 in the two sets of outer frames 20. After the double positioning block 40 is inserted into the adjacent positioning slots 24 in the two sets of outer frames 20 and is fixedly connected with them, the two adjacent sets of outer frames 20 located on the outer edge in several sets of extruded board units can be positioned and assembled by the double positioning block 40.

[0026] Example 2

[0027] See Figure 4 The difference between this embodiment and Embodiment 1 is that, in addition to the double positioning block 40, the connector also includes a quadruple positioning block 50. The shape of the quadruple positioning block 50 is the same as the shape of the gap between the adjacent positioning slots 24 in the four sets of outer frames 20. After the quadruple positioning block 50 is inserted into the adjacent positioning slots 24 in the four sets of outer frames 20 and locked in place, the adjacent four sets of outer frames 20 on the inner side of the several sets of extruded board units can be positioned and assembled by the quadruple positioning block 50.

[0028] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as bonding, welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, bonding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
