Description

Technical Field

[0001] This utility model relates to the field of prefabricated sandwich composite wall technology, and in particular to a prefabricated sandwich composite wall with a fireproof structure. Background Technology

[0002] Composite panel walls, also known as sandwich panels or sandwich wall systems, are a type of wall system consisting of two outer panels and a core material in the middle. This wall structure is widely used in the construction industry due to its efficient heat insulation, sound insulation performance, and rapid installation characteristics.

[0003] Patent CN208815709U discloses a composite material insulation board wall. It includes an insulation board body, a connecting layer fixedly connected to the top of the insulation board body, rubber tubes fixedly connected at equal intervals to the center of the top inner side of the connecting layer, the bottoms of multiple rubber tubes connected to the top of the insulation board body, sponge rings fixedly connected around the circumference of the inner cavity of the rubber tubes, soft cotton blocks fixedly connected to both sides of the inner side of the rubber tubes, and first springs fixedly connected at equal intervals to the bottom of the inner side of the rubber tubes. The wall constructed using this patent, when impacted, first strikes the connecting layer, and then the sponge rings inside the rubber tubes weaken the impact, thus reducing the impact force. However, since the insulation board body and its upper structure are mostly made of flammable materials, in the event of a fire, the flammable materials such as the insulation board body will burn rapidly, causing flames to penetrate the wall and spread the fire quickly from one room or area to another. Furthermore, the wall may collapse due to burning, affecting nearby vegetation and buildings, posing a significant safety hazard.

[0004] Therefore, there is a need to provide a prefabricated sandwich composite wall with a fire-resistant structure, in which the composite wall has high-temperature fire resistance through ceramic fiber boards. Utility Model Content

[0005] To overcome the shortcomings of existing patents where the insulation board body and its upper structure are mostly made of flammable materials, in the event of a fire, the flammable materials such as the insulation board body will burn rapidly, causing the flames to penetrate the wall and spread the fire quickly from one room or area to another. Furthermore, the wall may collapse due to burning, affecting nearby vegetation and houses, posing a great safety hazard. This utility model provides a prefabricated sandwich composite wall with a fireproof structure, which uses ceramic fiberboard to give the composite wall a high-temperature fireproof function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a prefabricated sandwich composite panel wall with a fireproof structure, comprising a first composite panel wall, a second composite panel wall, and connecting plates. The second composite panel wall is disposed on the first composite panel wall, and connecting plates are fixedly connected to both the first and second composite panel walls. The feature is that it further comprises ceramic fiber boards and fasteners. Two ceramic fiber boards are disposed on both the first and second composite panel walls. Multiple sets of second slots are formed on the first and second composite panel walls, with two slots in each set symmetrically positioned vertically. The second composite panel wall is inserted into the second slots. A set of fasteners is symmetrically and slidably disposed on both the left and right sides of the first and second composite panel walls, with two fasteners in each set, and the fasteners are inserted into adjacent ceramic fiber boards.

[0007] As a preferred technical solution of this utility model, it also includes a first elastic element and a locking block. Two locking blocks are slidably arranged on the connecting plate. The locking blocks are connected to the connecting plate by the first elastic element. Two first locking grooves are opened on the connecting block.

[0008] As a preferred technical solution of this utility model, it also includes a trapezoidal block, a limiting block, and a second elastic element. Two trapezoidal blocks are fixedly connected to the first composite panel wall, and two limiting blocks are slidably arranged on the trapezoidal blocks. The limiting blocks are inserted into the second composite panel wall, and a second elastic element is connected between the limiting blocks and the trapezoidal blocks.

[0009] As a preferred technical solution of this utility model, it also includes a U-shaped mounting plate, a first reinforcing frame and a second reinforcing frame. The U-shaped mounting plate is fixedly connected to both the first composite panel wall and the second composite panel wall. The first reinforcing frame is fixedly connected to the upper U-shaped mounting plate and is located inside the first composite panel wall. The second reinforcing frame is fixedly connected to the lower U-shaped mounting plate and is located inside the second composite panel wall. The first reinforcing frame and the second reinforcing frame are snapped together.

[0010] As a preferred technical solution of this utility model, the sound insulation board is fixedly connected to both the first composite board wall and the second composite board wall.

[0011] As a preferred technical solution of this utility model, it also includes a filling groove on a ceramic fiber plate located above the second composite wall.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By installing ceramic fiber boards on the first composite wall and the second composite wall, and then inserting clips into the ceramic fiber boards, multiple ceramic fiber boards are used to form a fire wall, which serves as a fireproof structure. Moreover, the ceramic fiber boards are made of ceramic fibers, which are suitable for heat insulation in extreme high-temperature environments and can withstand temperatures up to 1260℃ or even higher. Thus, when encountering flames, they can slow down the burning speed and prevent the spread of fire.

[0013] 2. By placing the first composite panel wall and the second composite panel wall on the same horizontal line, and then pushing the two composite panel walls towards each other, the locking block on the second composite panel wall is locked into the first locking groove of the first composite panel wall, thereby installing the two composite panel walls together, simplifying the installation process.

[0014] 3. By lifting the first composite panel wall above the second composite panel wall, aligning the limiting block on the first composite panel with the locking hole on the second composite panel wall, and then moving the first composite panel downward, the limiting block and trapezoidal block are locked into the second composite panel wall. This also allows the first composite panel to be quickly fixed to the second composite panel wall, thereby improving work efficiency and shortening the construction cycle.

[0015] 4. By connecting the first and second reinforcing frames, the U-shaped mounting plate, the first and second reinforcing frames form a triangular stable structure, thereby enhancing the support capacity and overall stability of the composite panel wall. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0024] Example 1: A prefabricated sandwich composite panel wall with a fireproof structure, see reference. Figures 1-5 As shown, the system includes a first composite panel wall 1, a second composite panel wall 2, and a connecting plate 201. The second composite panel wall 2 is installed on the first composite panel wall 1. The connecting plate 201 is fixedly connected to the middle of both the first composite panel wall 1 and the second composite panel wall 2. The connecting plate 201 is made of fireproof material. The system also includes ceramic fiber board 6 and fasteners 7. Ceramic fiber board 6 is symmetrically installed vertically on the front side of both the first composite panel wall 1 and the second composite panel wall 2. A set of second slots 601 is symmetrically opened vertically on both the left and right sides of both the first composite panel wall 1 and the second composite panel wall 2. There are two second slots 601 in the set of second slots 601, which are symmetrical vertically. The second composite panel wall 2 is inserted into the second slots 601. A set of fasteners 7 is symmetrically slidably installed vertically on both the left and right sides of both the first composite panel wall 1 and the second composite panel wall 2. There are two fasteners 7 in the set of fasteners 7, which are inserted into the adjacent ceramic fiber board 6.

[0025] See Figure 5 As shown, it also includes a sound insulation board 14. The sound insulation board 14 is fixedly connected to the rear side of both the first composite board wall 1 and the second composite board wall 2.

[0026] See Figure 1 and Figure 2 As shown, it also includes a filler groove 15 on a ceramic fiber board 6 located above the second composite wall 2.

[0027] When using precast sandwich composite wall panels to construct walls, cement is first applied to the surfaces of the second composite wall panel 2 that need to contact the first composite wall panel 1. Then, the first composite wall panel 1 is placed on the second composite wall panel 2, allowing the cement to bond the two composite walls together. Ceramic fiberboards 6 are installed on the first and second composite walls 1 and 2, and clips 7 are inserted into the ceramic fiberboards 6, so that multiple ceramic fiberboards 6 form a fire wall, thus serving as a fireproof structure. The ceramic fiberboards 6 are made of ceramic fibers and are suitable for heat insulation in extreme high-temperature environments, capable of withstanding temperatures up to 1260℃ or even higher. This allows them to slow down the burning rate and prevent the spread of fire when exposed to flames. Filling the filling groove 15 with cement can reinforce two adjacent ceramic fiberboards 6. The sound insulation board 14 enables the wall to have sound insulation function after construction.

[0028] Example 2: Based on Example 1, refer to Figures 1-3As shown, it also includes a first elastic element 3 and a locking block 4. The locking block 4 is symmetrically and slidably arranged on the left side of the connecting plate 201. The first elastic element 3 is connected between the locking block 4 and the connecting plate 201. The first locking groove 5 is symmetrically opened on the right side of the connecting block.

[0029] See Figure 4 As shown, it also includes a trapezoidal block 8, a limiting block 9, and a second elastic element 10. The bottom of the first composite wall 1 is symmetrically and fixedly connected with trapezoidal blocks 8. The lower left and right sides of the trapezoidal block 8 are slidably provided with limiting blocks 9. The limiting blocks 9 are inserted into the second composite wall 2. The limiting blocks and the trapezoidal blocks 8 are connected by the second elastic element 10.

[0030] When the composite wall needs to be constructed horizontally, the first composite panel wall 1 and the second composite panel wall 2 are placed on the same horizontal line, and then the two composite panel walls are pushed towards each other, so that the locking block 4 on the second composite panel is engaged in the first locking groove 5 of the first composite panel wall 1, thereby installing the two composite panel walls together and simplifying the installation process. When the composite wall needs to be constructed vertically, the first composite panel wall 1 is lifted above the second composite panel wall 2, so that the limiting block 9 on the first composite panel is aligned with the locking hole on the second composite panel wall 2, and then the first composite panel is moved downward, so that the limiting block 9 and the trapezoidal block 8 are engaged in the second composite panel wall 2. The second elastic element 10 deforms accordingly, thereby quickly fixing the first composite panel to the second composite panel wall 2, thus improving work efficiency and shortening the construction cycle.

[0031] See Figure 5 and Figure 6 As shown, it also includes a U-shaped mounting plate 11, a first reinforcing frame 12, and a second reinforcing frame 13. The U-shaped mounting plate 11 is fixedly connected to the middle of both the first composite panel wall 1 and the second composite panel wall 2. The first reinforcing frame 12 is welded to the upper rear side of the upper U-shaped mounting plate 11 and is located inside the first composite panel wall 1. The second reinforcing frame 13 is welded to the lower rear side of the lower U-shaped mounting plate 11 and is located inside the second composite panel wall 2. The first reinforcing frame 12 and the second reinforcing frame 13 are snapped together. The first reinforcing frame 12, the second reinforcing frame 13, and the U-shaped mounting plate 11 form a triangular structure to enhance the support capacity.

[0032] When the first composite panel wall 1 and the second composite panel wall 2 are installed together, the first reinforcing frame 12 and the second reinforcing frame 13 are engaged to form a triangular stable structure, thereby enhancing the support capacity and overall stability of the composite panel wall.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
