Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, specifically to a fireproof and heat-insulating curtain wall. Background Technology

[0002] A curtain wall is a non-load-bearing exterior wall covering of a building. It is hung up like a curtain, hence the name "curtain wall". It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings, and usually needs to have fireproof and heat insulation functions.

[0003] For example, patent application number CN201110167229.0 discloses a fireproof device for external thermal insulation materials of high-rise building curtain walls. The device includes external decorative materials, an insulation layer, and a building structural wall. Several airflow baffles are installed between the external decorative materials and the insulation layer, with each pair of upper and lower airflow baffles forming a closed space. The airflow baffles are movable fireproof thin plates that can be placed flat or tilted. A longitudinal main gas pipeline is installed between the external decorative materials and the insulation layer, passing through each layer of airflow baffles. Transverse branch gas pipelines are installed in each closed space, each connected to the main gas pipeline. Control valves and nozzles are installed on the branch gas pipelines. This device uses airflow baffles to divide the hollow structure inside the high-rise building curtain wall material into many closed spaces, avoiding the chimney effect during a fire. Simultaneously, flame-retardant gas is sprayed into the corresponding closed spaces through the branch gas pipelines, effectively reducing the rate of combustion spread of the insulation material or suffocating the flames.

[0004] However, in the current fireproof and heat-insulating curtain wall structure, the wall structure is relatively simple, and the decorative colors and styles on the outside of the curtain wall are also monotonous. When a fire breaks out, it cannot automatically extinguish the fire or prevent the spread of the fire.

[0005] Therefore, a fireproof and heat-insulating curtain wall is needed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings and defects of the prior art and provide a fireproof and heat-insulating curtain wall that enables the intermediate wall blocks and end wall blocks to be assembled and connected to each other, and can also increase the decorative effect. In the event of a fire, the sealing plate can be cracked to allow tap water and nitrogen to spray out, effectively blocking the spread of fire or automatically extinguishing the fire.

[0007] The objective of this invention is achieved through the following technical solution:

[0008] A fireproof and heat-insulating curtain wall is assembled from multiple intermediate wall blocks and end wall blocks.

[0012] As a preferred technical solution of the present invention, the upper end of the outer heat insulation plate is provided with a long slot, the bottom end of the long slot is provided with a connecting hole, and the connecting hole penetrates the outer heat insulation plate. The strip-shaped plug is engaged in the long slot, and the inner tube is inserted into the connecting hole.

[0013] As a preferred embodiment of the present invention, both ends of the heat insulation plate frame of the intermediate wall block are provided with assembly grooves, and a connecting pipe A and a lower insert block are provided in the assembly groove at one end of the heat insulation plate frame. The two connecting pipes A are respectively connected to the gas chamber and the liquid chamber. The connecting pipes A are fixed between the three lower insert blocks. A connecting sleeve A and an upper insert block are provided in the assembly groove at the other end of the heat insulation plate frame. The two connecting sleeves A are respectively connected to the gas chamber and the liquid chamber. The connecting sleeve A is fixed between the three upper insert blocks.

[0014] As a preferred technical solution of the present invention, when assembling the two sets of intermediate wall blocks, the connecting tube A of one set of intermediate wall blocks is inserted into the connecting sleeve A of the other set of intermediate wall blocks, and the lower insert and the upper insert are respectively inserted into the corresponding assembly slots.

[0015] As a preferred embodiment of the present invention, the outer end of the connecting tube A is provided with three sets of annular grooves, and a rubber sealing ring is fitted inside the three sets of annular grooves.

[0016] As a preferred technical solution of the present invention, one end of the heat insulation plate frame of the end wall block is provided with a through-hole cavity, one end of the through-hole cavity is provided with the gas cavity and the liquid cavity, a connecting pipe B or a connecting sleeve B is provided in the through-hole cavity, and the connecting pipe B or the connecting sleeve B has an L-shaped structure. One end of the connecting pipe B or the connecting sleeve B is connected to the gas cavity and the liquid cavity, and the other end of the connecting pipe B or the connecting sleeve B extends to the outside of the heat insulation plate frame.

[0017] As a preferred embodiment of the present invention, the connecting tube B is provided with a circular slot at the outer end of the heat insulation plate frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. This invention uses a multi-layered structure to assemble and connect wall blocks, and then splices several wall blocks together to form a curtain wall, which can enhance the decorative effect. In addition, two closed cavities for storing fire extinguishing materials are set in the heat insulation plate frame in the middle of the wall blocks. The closed cavities can be connected to the outside through the cooperation of pipes and holes. The holes are then blocked with plastic sealing plates. In the event of a fire, the sealing plates can be burned and cracked, allowing the materials in the closed cavities, such as tap water and nitrogen, to be sprayed out, thereby effectively preventing the spread of fire or automatically extinguishing the fire.

[0021] 2. This invention sets up intermediate wall blocks and end wall blocks according to different areas of the curtain wall. Both ends of the intermediate wall blocks need to be connected, so connecting pipes are placed at both ends of the insulation board frame. The outer ends of the end wall blocks do not need to be connected; therefore, a through-hole is set inside the insulation board frame facing the outer end of the end wall block, and an L-shaped connecting pipe is then installed to the side end of the insulation board frame, allowing the side ends of the end wall blocks to be connected. This does not affect the appearance of the curtain wall and allows the gas chambers and liquid chambers of the curtain wall to communicate with each other, making filling more convenient. Furthermore, the intermediate wall blocks and end wall blocks have the same structural composition, ensuring that the wall blocks have the same thickness, resulting in higher flatness of the assembled curtain wall.

[0036] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] like Figure 1-12 As shown, the specific implementation process of the present invention is as follows: A fireproof and heat-insulating curtain wall is assembled from multiple intermediate wall blocks and end wall blocks. Each intermediate wall block and end wall block includes a flame-retardant decorative panel 1, an outer heat insulation panel 3, a heat insulation panel frame 4, an inner heat insulation panel 5, and a heat insulation board 6, ensuring that the wall blocks have the same thickness and the assembled curtain wall has high flatness. The outer heat insulation panel 3 and the inner heat insulation panel 5 are respectively fixedly connected to both ends of the heat insulation panel frame 4 to play a double-layer heat insulation role. The flame-retardant decorative panel 1 is then connected to the outer end of the outer heat insulation panel 3, and a flame-retardant decorative strip 2 is provided between the flame-retardant decorative panel 1 and the outer heat insulation panel 3, which can not only improve the decorative effect of the intermediate wall blocks and end wall blocks, but also have strong fire resistance. Finally, the heat insulation board 6 is connected to the inner end of the inner heat insulation panel 5 to achieve the purpose of heat insulation.

[0040] The heat insulation frame 4 includes a sealing partition 401 that divides the interior of the frame into a gas chamber 402 and a liquid chamber 403. These two chambers can hold fire-extinguishing gases and liquids, such as nitrogen and water. A flame-retardant decorative strip 2 is connected to both the gas chamber 402 and the liquid chamber 403. A sealing plate 204 is positioned at the upper end of the flame-retardant decorative strip 2, exposed outside the flame-retardant decorative panel 1. In the event of a fire, the sealing plate 204 can be broken, allowing nitrogen in the gas chamber 402 and water in the liquid chamber 403 to be ejected, thus preventing the fire from spreading or automatically extinguishing it.

[0041] like Figure 3 , 4 As shown, the flame-retardant decorative panel 1 has an inverted U-shaped structure, and semi-circular locking protrusions 101 are provided at both ends of the inner side of the flame-retardant decorative panel 1. At the same time, semi-circular grooves 301 are provided at both ends of the outer heat insulation plate 3, so that the flame-retardant decorative panel 1 can be inserted into the outer heat insulation plate 3 by engaging the locking protrusions 101 and the semi-circular grooves 301. In addition, a long strip-shaped stepped locking hole 102 is provided on the inner side of the upper end of the flame-retardant decorative panel 1, so that the upper end of the flame-retardant decorative strip 2 can be locked and fixed in the stepped locking hole 102, making assembly more convenient.

[0042] like Figures 2-3 As shown in Figures 7 and 8, the upper end of the flame-retardant decorative strip 2 is provided with a stepped locking block 201, and the lower end of the flame-retardant decorative strip 2 is provided with a strip-shaped insert 202. During assembly, the stepped locking block 201 is engaged in the stepped locking hole 102 of the flame-retardant decorative panel 1, and the strip-shaped insert 202 is inserted into the long slot 302 at the upper end of the outer heat insulation panel 3. The stepped locking block 201 and the strip-shaped insert 202 are integrally injection molded structures, which are simple in structure, easy to assemble, and have high structural stability. Then, through holes 205 are provided on the flame-retardant decorative strip 2. In this embodiment, nine sets are provided. The through holes 205 penetrate the stepped locking block 201 and the strip-shaped insert 202, forming... The circuit is in the conductive state, and a retaining ring 206 is provided at the upper end of the through hole 205. The sealing plate 204 is fixedly connected to the upper end of the retaining ring 206 using internal hexagonal self-tapping screws. A rubber ring is pasted on the inner side to facilitate the sealing of the outer end of the through hole 205 through the sealing plate 204. The lower end of the through hole 205 is connected to an inner tube 203. After assembly, the inner tube 203 connects the gas chamber 402 and the liquid chamber 403 of the heat insulation frame 4. The outer side of the sealing plate 204 is a plastic plate. In the event of a fire, the sealing plate 204 can be burned and cracked, causing the nitrogen in the gas chamber 402 and the tap water in the liquid chamber 403 to spray out, thereby preventing the spread of fire or automatically extinguishing the fire.

[0043] like Figure 5 , 6As shown, the upper end of the outer heat insulation plate 3 is provided with a long slot 302, and two long slots 302 are provided, corresponding to the upper ends of the gas chamber 402 and the liquid chamber 403 respectively. A connecting hole 303 is provided at the bottom end of the two long slots 302. The connecting hole 303 needs to penetrate the outer heat insulation plate 3 so as to communicate with the gas chamber 402 and the liquid chamber 403. During assembly, the strip-shaped insert 202 at the lower end of the flame-retardant decorative strip 2 is engaged in the long slot 302, and the inner insert tube 203 is inserted into the connecting hole 303, so that the fire extinguishing material in the cavity can flow out through the cooperation of the tube and the hole to extinguish the fire.

[0044] like Figures 1-9 As shown, this is a structural schematic diagram of the middle wall block. The sealing partition 401 of the heat insulation plate frame 4 directly divides the interior into two parts: a gas chamber 402 and a liquid chamber 403. Assembly grooves 404 are provided at both ends of the heat insulation plate frame 4. A lower insert block 405 and a connecting tube A406 are sealed and inserted in the assembly groove 44 at one end of the heat insulation plate frame 4, and an upper insert block 407 and a connecting sleeve A408 are sealed and inserted in the assembly groove 404 at the other end. In this embodiment, three sets of lower insert blocks 405 and upper insert blocks 407 are provided, and two sets of connecting tubes A406 and connecting sleeves A408 are provided. The connecting tubes A406 and connecting sleeves A408 are connected to the gas chamber 402 and the liquid chamber 403, respectively. The three sets of lower insert blocks 405 and upper insert blocks 407 respectively clamp the connecting tubes A406 and connecting sleeves A408 in the middle position. When assembling the two sets of intermediate wall blocks, the connecting tube A406 of one set of intermediate wall blocks is inserted into the connecting sleeve A408 of the other set of intermediate wall blocks, and the lower insert 405 and the upper insert 407 are respectively inserted into the corresponding assembly slots 404, so that the outer end is neat and flat after the curtain wall is assembled as a whole. In addition, three sets of annular grooves are provided at the outer end of the connecting tube A406, and rubber sealing rings are fitted in the three sets of annular grooves respectively. The three sets of rubber sealing rings can be used to seal the connection. After the two sets of intermediate wall blocks are assembled and connected, the connecting tube A406 and the connecting sleeve A408 can be sealed to prevent gas or tap water from flowing out.

[0045] like Figures 10-12As shown, this is a structural schematic diagram of the end wall block. The sealing partition 401 of the heat insulation plate frame 4 has a "T" shaped structure, which divides the interior into three parts: a gas chamber 402, a liquid chamber 403, and a through-pipe chamber 409. The through-pipe chamber 409 is located at one end of the heat insulation plate frame 4, while the other end of the heat insulation plate frame 4 is also provided with an assembly groove 404. An L-shaped connecting pipe B410 or a connecting sleeve B411 is provided in the through-pipe chamber 409, and a corresponding connecting sleeve B411 or connecting pipe B410 should also be provided in the assembly groove 404. Therefore, two types of end wall blocks will appear. The first type has connecting pipes B410 installed in the through-hole 409 of the insulation plate frame 4. One end of the two connecting pipes B410 is connected to the gas chamber 402 and the liquid chamber 403 respectively, and the other end of the two connecting pipes B410 is exposed outside the insulation plate frame 4. The other end of the insulation plate frame 4 has connecting sleeves B411 and upper inserts 407 installed in the assembly groove 404 at the other end of the insulation plate frame 4. Three sets of upper inserts 407 are installed to clamp the two connecting sleeves B411 in the middle position, so that the two connecting sleeves B411 are connected to the gas chamber 402 and the liquid chamber 403 respectively. The first type is a connection between cavity 403 and the second type is a connection sleeve B411 installed in the through-hole cavity 409 of the heat insulation plate frame 4. One end of the two connection sleeves B411 is connected to the gas cavity 402 and the liquid cavity 403 respectively, and the other end of the two connection sleeves B411 is exposed outside the heat insulation plate frame 4. The other end of the heat insulation plate frame 4 is equipped with a connection insertion tube B410 and a lower insertion block 405 in the assembly groove 404 at the other end of the heat insulation plate frame 4. Alternatively, three sets of lower insertion blocks 405 are set to clamp the two connection insertion tubes B410 in the middle position, so that the two connection insertion tubes B410 are connected to the gas cavity 402 and the liquid cavity 403 respectively.

[0046] During assembly, the two types of end wall blocks are assembled. The connecting pipe B of the first type of wall block is sealed and inserted into the connecting sleeve B of the second type of wall block to achieve side-end connection of the end wall blocks. Three sets of rubber sealing rings are also provided on the connecting pipe B411. A circular slot 412 is also provided at the outer end of the connecting pipe B410 that protrudes from the heat insulation frame 4. During assembly, the outer ends of the connecting sleeves B411 are inserted into the circular slots 412 to achieve a tight connection. The end structure of one end of the end wall block is similar to that of the end of the middle wall block. Similarly, by using compatible intermediate wall blocks connected to the ends of the end wall blocks, the vertical connection is very convenient, enabling gas cavities and liquid cavities to communicate with each other. This allows for communication between gas cavities and liquid cavities throughout the curtain wall, facilitating the filling of nitrogen into the gas cavities and tap water into all the liquid cavities, filling them sequentially downwards. In the event of a fire, the sealing plate can be cracked, allowing the nitrogen in the gas cavities and the tap water in the liquid cavities to be ejected, thereby preventing the spread of fire or automatically extinguishing it.

[0047] The embodiments described above are merely illustrative of implementation methods of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
