Description

Technical Field

[0001] The invention relates to the technical field of curtain walls, in particular to a steel energy-saving curtain wall structure. Background Art

[0002] Steel curtain wall, also known as steel structure curtain wall, is a modern building curtain wall system supported by a steel structure system and composed of a variety of materials such as glass, aluminum alloy, stone, etc. At present, energy-saving curtain wall profiles of steel square tubes + aluminum-plastic co-extruded parts + nylon 66 composite PU foam insulation core are mostly used to form steel energy-saving curtain walls to meet the requirements of ultra-low energy consumption and energy-saving specifications, reduce carbon emissions and save costs.

[0003] At present, the curtain wall panels and steel structures are mostly sealed by sealing strips or sealants, but these two sealing methods have the following defects:

[0004] 1. The sealing method using sealing strips has fixed specifications and is difficult to apply to curtain walls of different sizes. Moreover, after long-term use, the strips may age, become loose or droop, affecting the sealing effect.

[0005] 2. When using sealant to seal, it is difficult for workers to effectively fill and seal the gaps with sealant where the gaps are small. In addition, the sealant is prone to aging and cracking after long-term use, which affects the sealing effect. Summary of the invention

[0006] Based on this, it is necessary to provide a steel energy-saving curtain wall structure to address the problem that the steel energy-saving curtain wall structure has poor sealing effect and is difficult to ensure its long-term operation.

[0007] A steel energy-saving curtain wall structure comprises a steel square tube, an aluminum-plastic co-extruded frame, a nylon composite polyurethane foam insulation core, an aluminum-plastic co-extruded board, a curtain wall board and a foamed plastic insulation board, wherein the aluminum-plastic co-extruded frame is fixedly connected to one end of the steel square tube, the nylon composite polyurethane foam insulation core is fixedly connected to one end of the aluminum-plastic co-extruded frame, the aluminum-plastic co-extruded board is fixedly connected to one end of the nylon composite polyurethane foam insulation core, the foamed plastic insulation board is plugged into one end of the aluminum-plastic co-extruded frame, the curtain wall board is arranged between the foamed plastic insulation board and the aluminum-plastic co-extruded board, a bearing device is arranged between the foamed plastic insulation board and the aluminum-plastic co-extruded board, and the curtain wall board is plugged into the inner side of the bearing device.

[0008] Furthermore, the supporting device includes an installation frame, evenly distributed sealing mechanisms and evenly distributed adjustment mechanisms. The installation frame is clamped between the foamed plastic insulation board and the aluminum-plastic co-extruded board, the curtain wall panel is inserted into the inner side of the installation frame, and two relatively vertical inner walls of the installation frame are provided with transverse grooves, and the inner bottom wall of the installation frame is provided with installation cavities that are connected to the two transverse grooves. The sealing mechanism is embedded and installed in the interior of the installation cavity, and the two ends of the sealing mechanism respectively penetrate into the interior of the two transverse grooves, and the adjustment mechanism is installed in the interior of the sealing mechanism.

[0009] Furthermore, the sealing mechanism includes an extrusion airbag, two box-shaped airbags, a rubber storage bag and a needle. The extrusion airbag is embedded and installed inside the installation cavity, and the two ends of the extrusion airbag respectively penetrate into the interior of the two transverse grooves. The two box-shaped airbags are respectively fixedly connected and connected to the two ends of the extrusion airbag, the rubber storage bag is fixedly connected to the inner top wall of the box-shaped airbag, the interior of the rubber storage bag is filled with sealant, and the needle is fixedly connected to the inner bottom wall of the rubber storage bag.

[0010] In one of the embodiments, the squeezing force of the curtain wall panel penetrating into the installation frame is used to expand the box-shaped airbag, so that the gap between the curtain wall panel and the installation frame is sealed. There is no need for the staff to perform the sealing operation separately, so as to reduce the installation burden of the staff. At the same time, the lateral expansion and sealing of the box-shaped airbag can also compensate for the size error, so as to improve the sealing between the curtain wall panel and the installation frame. Moreover, since the box-shaped airbag is always hidden between the curtain wall panel and the installation frame, the probability of the box-shaped airbag being exposed to wind and sun is effectively reduced, so as to reduce the aging rate of the box-shaped airbag. Moreover, when the box-shaped airbag expands, it can also drive the needle to pierce the plastic storage bag, so that the sealant firmly bonds the curtain wall panel and the box-shaped airbag together, which effectively reduces the probability of gaps between the curtain wall panel and the box-shaped airbag, and further improves the sealing effect between the curtain wall panel and the installation frame.

[0011] Furthermore, the regulating mechanism comprises an elastic hose, which is fixedly connected to the interior of the extrusion airbag, and both ends of the elastic hose respectively penetrate into the interiors of the two box-shaped airbags, and the interior of the elastic hose is filled with water.

[0012] In one of the embodiments, an elastic hose and an elastic liquid storage bag filled with water are used. When the box-shaped airbag is in a high temperature environment, the water can lower the temperature inside the box-shaped airbag, effectively reducing the probability of the box-shaped airbag relaxing and expanding. In a sub-zero environment, the water increases the squeezing force on the nitrogen by freezing, and the nitrogen squeezes and expands the box-shaped airbag, so that the box-shaped airbag always remains firm. This effectively reduces the probability of the box-shaped airbag being affected by thermal expansion and contraction, and further improves the sealing effect between the curtain wall panel and the mounting frame.

[0013] Furthermore, the number of the needles is not less than ten, and the needles are arranged directly below the plastic storage bag.

[0014] In one embodiment, this can increase the channel for the sealant to flow out, thereby accelerating the utilization rate of the sealant.

[0015] Furthermore, an adjustment plate is fixedly connected to the inner bottom wall of the box-shaped airbag, and the puncture needle is fixedly connected to the top of the adjustment plate.

[0016] In one embodiment, this can drive all the needles to operate synchronously to avoid the possibility that a certain needle punctures the box-shaped airbag due to deviation.

[0017] Furthermore, the opposite ends of the needle and the adjustment plate are each provided with a liquid conducting channel, and two adjacent liquid conducting channels are connected.

[0018] In one embodiment, this can increase the flow path for the sealant to flow out, further accelerating the utilization rate of the sealant.

[0019] Furthermore, the inner top wall of the box-shaped airbag is fixedly connected to a protection box, and the plastic storage bag is fixedly connected to the inner top wall of the protection box.

[0020] In one embodiment, this can prevent the puncture needle from penetrating the plastic storage bag and then puncturing the box-shaped airbag, further ensuring the integrity of the box-shaped airbag.

[0021] Furthermore, the interiors of the extruded airbag and the box-shaped airbag are both filled with nitrogen.

[0022] In one of the embodiments, nitrogen is used as the filling gas. This not only reduces the probability of the filling gas reacting with the surrounding structure, but also when the flame burns the extrusion airbag or the box-shaped airbag, the nitrogen can isolate the surrounding oxygen, which can increase the burning difficulty of the flame to achieve the effect of extinguishing the fire.

[0023] Furthermore, both ends of the elastic hose are fixedly connected and communicated with an elastic liquid storage bag, and the interior of the elastic liquid storage bag is filled with water.

[0024] In one embodiment, this can increase the indirect contact area of ​​water with the box-shaped airbag.

[0025] Furthermore, the diameter of the elastic hose is smaller than the inner diameter of the connection point between the extrusion airbag and the box-shaped airbag, and the shape of the elastic liquid storage bag is rectangular.

[0026] The above-mentioned steel energy-saving curtain wall structure utilizes the extrusion force of the curtain wall panel deep into the installation frame to expand the box-shaped airbag, so that it seals the gap between the curtain wall panel and the installation frame, and there is no need for the staff to perform the sealing operation separately, so as to reduce the installation burden of the staff. At the same time, the lateral expansion and sealing of the box-shaped airbag can also make up for the size error between the curtain wall panel and the installation frame, so as to improve the sealing degree between the curtain wall panel and the installation frame. Moreover, since the box-shaped airbag is always hidden between the curtain wall panel and the installation frame, the probability of the box-shaped airbag being exposed to wind and sun is effectively reduced, so as to reduce the aging rate of the box-shaped airbag. Moreover, when the box-shaped airbag expands, it can also drive the needle to pierce the plastic storage bag, so that the sealant firmly bonds the curtain wall panel and the box-shaped airbag together, which effectively reduces the probability of a gap between the curtain wall panel and the box-shaped airbag, and further improves the sealing effect between the curtain wall panel and the installation frame.

[0027] At the same time, an elastic hose and an elastic liquid storage bag filled with water are used. When the box-shaped airbag is in a high temperature environment, the water can lower the temperature inside the box-shaped airbag, effectively reducing the probability of the box-shaped airbag relaxing and expanding. In a sub-zero environment, water increases the squeezing force on the nitrogen by freezing, and the nitrogen then squeezes and expands the box-shaped airbag, so that the box-shaped airbag always remains firm, which effectively reduces the probability of the box-shaped airbag being affected by thermal expansion and contraction, and further improves the sealing effect between the curtain wall panel and the installation frame, which can improve the overall thermal insulation performance of the curtain wall, effectively reduce the heat load loss due to temperature difference heat transfer and the load intensity of solar radiation, and improve the energy efficiency of the building.

[0043] Combine the following Figure 1 - Figure 7 The steel energy-saving curtain wall structure of the present invention is described.

[0044] In one embodiment, a steel energy-saving curtain wall structure includes a steel square tube 100, an aluminum-plastic co-extruded frame 200, a nylon composite polyurethane foam insulation core 300, an aluminum-plastic co-extruded plate 400, a curtain wall panel 500 and a foam plastic insulation panel 700, wherein the aluminum-plastic co-extruded frame 200 is fixedly connected to one end of the steel square tube 100, the nylon composite polyurethane foam insulation core 300 is fixedly connected to one end of the aluminum-plastic co-extruded frame 200, the aluminum-plastic co-extruded plate 400 is fixedly connected to one end of the nylon composite polyurethane foam insulation core 300, the foam plastic insulation panel 700 is plugged into one end of the aluminum-plastic co-extruded frame 200, the curtain wall panel 500 is arranged between the foam plastic insulation panel 700 and the aluminum-plastic co-extruded plate 400, a bearing device 600 is arranged between the foam plastic insulation panel 700 and the aluminum-plastic co-extruded plate 400, and the curtain wall panel 500 is plugged into the inner side of the bearing device 600;

[0045] Existing aluminum alloy energy-saving curtain wall profiles usually use nylon 66 as a thermal break bridge for the outdoor glass support plate. Due to the strength requirements of the curtain wall, its length cannot be too large. This type of thermally-broken aluminum structure is more suitable for 75% energy-saving building curtain walls. When used with high energy-saving requirements, the glass curtain wall often fails to meet the energy-saving requirements. Therefore, the use of nylon composite polyurethane foam insulation core 300 helps to improve the energy-saving coefficient of the curtain wall; at the same time, the use of aluminum-plastic co-extruded micro-foam material helps to soundproof the entire curtain wall, especially the use of steel square tube 100 has better strength and longer fire resistance, which well solves the needs of green building and ultra-low energy consumption building passive curtain wall designers. The structural production process scheme of the energy-saving curtain wall profile of the present invention using steel square tube 100 + aluminum-plastic co-extruded frame 200 + nylon composite polyurethane foam insulation core 300 can meet the requirements of ultra-low energy consumption and energy-saving specifications, reduce carbon emissions, and save costs;

[0046] The staff needs to weld the steel square tube 100 in advance to form a keel frame for installing the curtain wall, and then lock the keel frame on the outer wall of the building through expansion bolts, and then fix the aluminum-plastic co-extruded frame 200 to the outside of the steel square tube 100 with screws. When the aluminum-plastic co-extruded frame 200 is installed. The staff then slides the foamed plastic insulation board 700 into the corresponding groove on the aluminum-plastic co-extruded frame 200, and then fixes the nylon composite polyurethane foam insulation core 300 and the aluminum-plastic co-extruded board 400 together through screws and nuts, and then slides the corresponding installation frame 610 into the corresponding groove between the foamed plastic insulation board 700 and the aluminum-plastic co-extruded board 400. When the three adjacent installation frames 610 together form a U-shape, the staff can slide the curtain wall panel 500 between the three installation frames 610, and finally slide another installation frame 610 between the unfixed side of the curtain wall panel 500 and the aluminum-plastic co-extruded board 400. At this time, the curtain wall panel 500 can be stably installed, and then the staff installs the corresponding number of curtain wall panels 500 on the outer wall of the building in the above manner.

[0047] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the bearing device 600 includes a mounting frame 610, evenly distributed sealing mechanisms 620 and evenly distributed adjusting mechanisms 630. The mounting frame 610 is clamped between the foamed plastic insulation board 700 and the aluminum-plastic co-extruded board 400. The curtain wall panel 500 is plugged into the inner side of the mounting frame 610. Two relatively vertical inner walls of the mounting frame 610 are provided with transverse grooves 611. The inner bottom wall of the mounting frame 610 is provided with mounting cavities 612 that are connected to the two transverse grooves 611. The sealing mechanism 620 is embedded and installed in the interior of the mounting cavity 612. The two ends of the sealing mechanism 620 respectively penetrate into the interior of the two transverse grooves 611. The adjusting mechanism 630 is installed in the interior of the sealing mechanism 620.

[0048] The box-shaped airbag 622 is inflated by the extrusion force of the curtain wall panel 500 deep into the installation frame 610 to seal the gap between the curtain wall panel 500 and the installation frame 610. The staff does not need to perform the sealing operation separately, so as to reduce the installation burden of the staff. At the same time, the lateral expansion and sealing of the box-shaped airbag 622 can also make up for the size error, so as to improve the sealing degree between the curtain wall panel 500 and the installation frame 610. In addition, since the box-shaped airbag 622 is always hidden between the curtain wall panel 500 and the installation frame 610, the sealing degree between the curtain wall panel 500 and the installation frame 610 is improved. This effectively reduces the probability of the box-shaped airbag 622 being exposed to wind and sun, thereby reducing the aging rate of the box-shaped airbag 622; and while the box-shaped airbag 622 is expanding, it can also drive the needle 624 to pierce the plastic storage bag 623, so that the sealant firmly bonds the curtain wall panel 500 and the box-shaped airbag 622 together, which effectively reduces the probability of a gap between the curtain wall panel 500 and the box-shaped airbag 622, and further improves the sealing effect between the curtain wall panel 500 and the mounting frame 610.

[0049] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the sealing mechanism 620 includes an extrusion airbag 621, two box-shaped airbags 622, a rubber storage bag 623 and a needle 624. The extrusion airbag 621 is embedded and installed in the interior of the installation cavity 612. The two ends of the extrusion airbag 621 respectively penetrate into the interior of the two transverse grooves 611. The two box-shaped airbags 622 are respectively fixedly connected and connected to the two ends of the extrusion airbag 621. The rubber storage bag 623 is fixedly connected to the inner top wall of the box-shaped airbag 622. The interior of the rubber storage bag 623 is filled with sealant. The needle 624 is fixedly connected to the inner bottom wall of the rubber storage bag 623.

[0050] The number of the needles 624 is not less than ten, and the needles 624 are arranged directly below the rubber storage bag 623; the inner bottom wall of the box-shaped airbag 622 is fixedly connected with an adjustment plate 625, and the needles 624 are fixedly connected to the top of the adjustment plate 625; the opposite ends of the needles 624 and the adjustment plate 625 are provided with liquid guide channels 626, and two adjacent liquid guide channels 626 are connected; the inner top wall of the box-shaped airbag 622 is fixedly connected with a protective box 627, and the rubber storage bag 623 is fixedly connected to the inner top wall of the protective box 627; the interior of the extrusion airbag 621 and the box-shaped airbag 622 are filled with nitrogen, and the design of using nitrogen as the filling gas can not only reduce the probability of the filling gas reacting with the surrounding structure, but also when the flame burns the extrusion airbag 621 or the box-shaped airbag 622, the nitrogen can also separate the surrounding oxygen, which can increase the burning difficulty of the flame to achieve the effect of extinguishing the fire.

[0051] When the staff inserts the curtain wall panel 500 into the installation frame 610, the curtain wall panel 500 squeezes the squeezing airbag 621 passing by, and the nitrogen inside the squeezing airbag 621 is squeezed into the box-shaped airbag 622. At this time, the box-shaped airbag 622 expands and squeezes the box-shaped airbags 622 on both sides and the facing curtain wall panel 500 along the transverse groove 611, which can effectively block the gap between the curtain wall panel 500 and the installation frame 610. In addition, since the box-shaped airbag 622 can expand around along the transverse groove 611, it can make up for the sealing error, so as to improve the sealing degree between the curtain wall panel 500 and the installation frame 610. In addition, since the box-shaped airbag 622 is always hidden between the curtain wall panel 500 and the installation frame 610, it effectively reduces the probability of the box-shaped airbag 622 being exposed to wind and sun, so as to reduce the aging rate of the box-shaped airbag 622.

[0052] During the expansion of the box-shaped airbag 622, the box-shaped airbag 622 simultaneously drives the rubber storage bag 623 and the needle 624 to approach each other. After the needle 624 penetrates into the interior of the rubber storage bag 623, during the subsequent squeezing of the rubber storage bag 623 by the box-shaped airbag 622, the sealant inside the rubber storage bag 623 quickly splashes out along the hole on the surface of the rubber storage bag 623 punctured by the needle 624, which can quickly fill the gap between the box-shaped airbag 622 and the curtain wall panel 500 until the sealant solidifies. At this time, the sealant can fix the box-shaped airbag 622 and the curtain wall panel 500 together, thereby improving the sealing effect between the curtain wall panel 500 and the mounting frame 610.

[0053] like Figure 4 and Figure 7As shown, the adjustment mechanism 630 includes an elastic hose 631, which is fixedly connected to the inside of the extrusion airbag 621, and the two ends of the elastic hose 631 respectively penetrate into the inside of the two box-shaped airbags 622, and the inside of the elastic hose 631 is filled with water; the two ends of the elastic hose 631 are fixedly connected and connected to the elastic liquid storage capsule 632, and the inside of the elastic liquid storage capsule 632 is filled with water; the diameter of the elastic hose 631 is smaller than the inner diameter of the connection between the extrusion airbag 621 and the box-shaped airbag 622, and the shape of the elastic liquid storage capsule 632 is rectangular;

[0054] By using an elastic hose 631 filled with water and an elastic liquid storage bag 632, when the box-shaped airbag 622 is in a high temperature environment, the water can lower the temperature inside the box-shaped airbag 622, effectively reducing the probability of the box-shaped airbag 622 relaxing and expanding. In a sub-zero environment, water increases the squeezing force on the nitrogen by freezing, and the nitrogen then squeezes and expands the box-shaped airbag 622, so that the box-shaped airbag 622 always remains firm, which effectively reduces the probability of the box-shaped airbag 622 being affected by thermal expansion and contraction, and further improves the sealing effect between the curtain wall panel 500 and the mounting frame 610.

[0055] When the temperature of the nitrogen inside the box-shaped airbag 622 is higher than the temperature of the water inside the elastic liquid storage bag 632, the water can absorb the nitrogen and the temperature of the surface of the box-shaped airbag 622, which can reduce the probability of over-expansion of the box-shaped airbag 622. When the ambient temperature is below zero, the water inside the elastic hose 631 and the elastic liquid storage bag 632 freezes. Since the volume of frozen water is larger than the volume of liquid water, the elastic hose 631 and the elastic liquid storage bag 632 expand and squeeze the nitrogen in the opposite direction, which can reduce the probability of contraction of the box-shaped airbag 622, so as to ensure that the box-shaped airbag 622 can always seal the gap between the curtain wall panel 500 and the mounting frame 610.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
