Description

Technical Field

[0001] This application relates to the technical field of curtain walls, and specifically to a curtain wall structure with good heat insulation performance. Background Art

[0002] A curtain wall is an exterior wall enclosure structure of a building, which has the characteristic of not bearing weight and is hung like a curtain, so it is also called a "curtain wall" or a "suspended wall". It is a lightweight wall with a decorative effect commonly used in modern large-scale and high-rise buildings. It is composed of a panel and a support structure system, and can have a certain displacement ability relative to the main structure or have a certain deformation ability by itself, but it does not bear the building exterior enclosure structure or decorative structure acting on the main structure.

[0003] In order to achieve heat insulation, the existing curtain walls adopt a double-layer curtain wall structure during installation. A thermal buffer zone is formed through the air interlayer between the inner and outer curtain walls, which can effectively reduce the influence of outdoor temperature fluctuations on the indoor temperature and improve the heat insulation effect. Its structure is a fixed connection method to ensure airtightness. Once damaged during use, the whole piece needs to be replaced, resulting in a relatively high maintenance cost. Moreover, the sealed installation of the double-layer curtain wall requires more sealing strips and support structures, and the installation cost is also relatively high.

[0004] Therefore, this application provides a curtain wall structure with good heat insulation performance to solve the above problems. Utility Model Content

[0005] This application provides a curtain wall structure with good heat insulation performance, aiming to solve the problem that the existing heat-insulating curtain walls with a double-layer curtain wall structure installed in a closed manner have relatively high installation and maintenance costs as mentioned in the background art.

[0006] To achieve the above object, this application provides the following technical solution: A curtain wall structure with good heat insulation performance, including a support member and a heat insulation board.

[0007] The support member is an outer frame filled with heat insulation material. First sealing strips and second sealing strips are symmetrically arranged on the inner side of the outer frame. Placement grooves matching the heat insulation board are opened on the mutually approaching surfaces of the first sealing strip and the second sealing strip. There are two heat insulation boards, which are respectively embedded in the two placement grooves. And a warm edge strip is arranged at the corresponding edge positions between the two heat insulation boards. A clamping frame is buckled on the outer frame and contacts the surface of the second sealing strip away from the heat insulation board. In this way, through the outer frame filled with heat insulation material, the embedding of the heat insulation board, the setting of the warm edge strip, and the buckling of the clamping frame, a multi-layer heat insulation structure is formed and sealed between the double-layer heat insulation boards, effectively reducing heat transfer and improving the heat insulation performance of the curtain wall. Compared with the traditional double-layer curtain wall structure, the single-layer structure reduces the number of sealing strips and support structures, thereby reducing the installation cost. And due to the buckling method of the clamping frame and the outer frame, it can be disassembled for replacement and maintenance when damaged locally, reducing the maintenance cost.

[0008] Preferably, there are clamping columns at positions corresponding to the four corners of the inner side of the outer frame, and clamping holes are opened at positions corresponding to the clamping columns on the clamping frame, and the clamping holes are equipped with hole plugs, so that the clamping frame can be firmly fixed on the outer frame, thereby improving the stability of the entire curtain wall structure. Through the simple cooperation of the clamping columns and the clamping holes, the clamping frame can be quickly installed and disassembled, which reduces the complexity and difficulty of installation, improves construction efficiency, and facilitates disassembly and maintenance.

[0009] Preferably, the side surface of the clamping column has a rubber ring with an outer diameter slightly larger than the inner diameter of the clamping hole, and the elasticity of the rubber ring is utilized to make the clamping column and the clamping hole closer, thereby improving the sealing performance and friction force.

[0010] Preferably, the filling material in the outer frame is polyurethane foam, which has multiple functions such as thermal insulation, heat insulation, sound insulation, fire prevention, and moisture resistance. It has high foaming properties, good sealing properties, and high bonding strength. It can effectively improve the thermal insulation performance of doors and windows and reduce the thermal conductivity of the profile.

[0011] Preferably, two handle grooves are symmetrically provided on the inner side of the card frame to facilitate applying force to the card frame during disassembly.

[0012] Preferably, the outer frame is equipped with an assembly frame for assembling multiple groups of the outer frames, so that the curtain wall structure can be assembled when dealing with a large area of ​​wall.

[0013] Preferably, the assembly frame is provided with a clearance groove, a filling piece is buckled on the clearance groove, and the assembly is assembled in a detachable installation manner to facilitate disassembly during subsequent maintenance.

[0014] Preferably, the filling piece includes a rubber strip for filling the make way groove and a flange fixed on the rubber strip away from the make way groove for limiting the outer frame on the inner side of the assembly frame. The rubber strip in the filling piece has good sealing properties, can effectively fill the gap between the outer frames, prevent air and moisture penetration, and improve the thermal insulation performance and durability of the curtain wall structure.

[0015] The curtain wall structure with good thermal insulation performance forms a multi-layer insulation structure by filling the outer frame with insulation material, embedding the insulation board, setting the warm edge strip and buckling the card frame, and forms a seal between the double-layer insulation board, which effectively reduces heat transfer and improves the thermal insulation performance of the curtain wall. Compared with the traditional double-layer curtain wall structure, the single-layer structure reduces the number of sealing strips and supporting structures, thereby reducing the installation cost; and due to the buckling method of the card frame and the outer frame, they can be disassembled for replacement and maintenance in the event of local damage, thereby reducing the maintenance cost.

[0016] The curtain wall structure with good thermal insulation avoids a large number of customized parts or special materials that may be required in traditional methods by introducing assembly frames and filling parts, thereby reducing production costs and avoiding the cost of overall replacement during later maintenance, thereby reducing maintenance costs.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Example 1

[0029] This embodiment provides a curtain wall structure with good thermal insulation properties, such as Figures 1-3 As shown, the curtain wall structure with good thermal insulation performance includes support members and insulation panels 2.

[0030] The support member is an outer frame 1 filled with heat-insulating material. On the inner side of the outer frame 1, a first sealing strip 4 and a second sealing strip 5 are symmetrically arranged. On the mutually approaching sides of the first sealing strip 4 and the second sealing strip 5, placing grooves 41 matching the heat-insulating plate 2 are provided. There are two heat-insulating plates 2 which are respectively installed in the two placing grooves 41. And at the positions corresponding to the edges between the two heat-insulating plates 2, a warm edge strip 3 is provided. A clamping frame 6 which contacts the side of the second sealing strip 5 away from the heat-insulating plate 2 is buckled on the outer frame 1.

[0031] During use, the first sealing strip 4, the first heat-insulating plate 2, the warm edge strip 3, the second heat-insulating plate 2 and the second sealing strip 5 are sequentially placed in the outer frame 1. Then the clamping frame 6 is buckled on the outer frame 1 and the first sealing strip 4, the first heat-insulating plate 2, the warm edge strip 3, the second heat-insulating plate 2 and the second sealing strip 5 are pressed tightly. Wherein the two heat-insulating plates 2 are respectively embedded in the placing grooves 41 of the first sealing strip 4 and the second sealing strip 5. Thus, the gap between the outer frame 1 and the heat-insulating plate 2 is isolated and sealed by the first sealing strip 4. The periphery of the two heat-insulating plates 2 is isolated and sealed by the warm edge strip 3 between the two heat-insulating plates 2, so that an airtight layer is formed between the two heat-insulating plates 2. At the same time, the gap between the clamping frame 6 and the heat-insulating plate 2 is isolated and sealed by the second sealing strip 5. The whole is kept sealed and the joints are isolated by the heat-insulating material. Thus, it has a good heat preservation effect, replaces the installation of the double-layer curtain wall, saves the installation cost. At the same time, because it has a detachable support structure, the later replacement and maintenance can be carried out by disassembling and replacing local parts, reducing the maintenance cost.

[0032] Specifically, at the positions corresponding to the four corners on the inner side of the outer frame 1, there are all clamping posts 11. At the positions corresponding to the clamping posts 11 on the clamping frame 6, clamping holes 61 are all provided. And the clamping holes 61 are equipped with hole plugs 7. When the clamping frame 6 is placed on the outer frame 1, the clamping holes 61 on the clamping frame 6 will correspond to the clamping posts 11 on the outer frame 1. By inserting the clamping posts 11 into the clamping holes 61, the firm connection between the clamping frame 6 and the outer frame 1 is realized. Then the hole plugs 7 are inserted into the clamping holes 61 to ensure the closed heat preservation performance and beauty.

[0033] Furthermore, on the side of the clamping post 11, there is a rubber ring 111 whose outer diameter is slightly larger than the inner diameter of the clamping hole 61. When the clamping post 11 is inserted into the clamping hole 61, the gap between the two is filled by the rubber ring 111 to ensure sealing and improve the heat preservation effect.

[0034] It should be noted that the filling material in the outer frame 1 is polyurethane foam. Polyurethane foam has multiple functions such as heat preservation, heat insulation, sound insulation, fire prevention and moisture proof. It has high foaming property, good sealing performance and large bonding strength, and can effectively improve the heat insulation performance of the doors and windows and reduce the heat conduction coefficient of the profiles.

[0035] Furthermore, on the inner side of the clamping frame 6, two handle grooves 62 are symmetrically provided. During disassembly, the handle grooves 62 are used as the hand landing points, and then force is applied to pull the clamping frame 6 off the outer frame 1, thus saving effort.

[0036] Example 2

[0037] Unlike Example 1, when encountering a large area of ​​construction wall, the single curtain wall structure will increase the difficulty of production due to its large size, increase the production cost, and the maintenance cost of later damage is also greater. Figure 4 and Figure 5 As shown, the outer frame 1 is equipped with an assembling frame 8 for assembling multiple groups of outer frames 1. The assembling frame 8 has a clearance groove 81, and a filling piece 9 is buckled on the clearance groove 81.

[0038] The filling member 9 includes a rubber strip 91 for filling the clearance groove 81 and a flange 92 fixed to a side of the rubber strip 91 away from the clearance groove 81 for limiting the outer frame 1 on the inner side of the assembly frame 8 .

[0039] During assembly, first determine the required number and arrangement of outer frames 1 according to the size and shape of the wall, then install the outer frames 1 one by one on the assembly rack 8, and fill the gaps and limit the fixation through the clearance grooves 81 and the filling pieces 9. Finally, after all the outer frames 1 are assembled, a complete and stable curtain wall structure is formed. The assembly rack 8 provides a stable framework, so that multiple outer frames 1 can be combined into an integral curtain wall structure in a certain arrangement. The clearance grooves 81 opened on the assembly rack 8 are to adapt to and accommodate the gaps or special shapes between the outer frames 1, ensuring that the assembled curtain wall structure is flat and seamless. The specific operations are as follows.

[0040] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
