Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a building insulation curtain wall. Background Technology

[0002] A building curtain wall refers to the non-load-bearing exterior wall cladding of a building, typically composed of panels (glass, metal, stone, ceramic, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, glass ribs, etc.). A building curtain wall is an exterior envelope or decorative structure composed of a supporting structural system and panels, capable of some displacement relative to the main structure, and does not share the loads of the main structure. It is a non-load-bearing, curtain-like structure, hence also called a suspended wall, and is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It is a building envelope structure composed of a structural frame and inlaid panels, which does not bear the loads or actions of the main structure.

[0003] In existing metal panel curtain walls, the insulation layer is generally combined with the metal panel. Since the metal panel curtain wall is suspended from the exterior wall by a structure, the addition of the insulation layer makes the metal curtain wall too heavy, which is inconvenient to install. The insulation layer is also prone to falling off, causing safety accidents. In addition, the existing metal curtain walls have poor waterproof and fireproof effects, which can cause the insulation layer to age prematurely, reduce its service life, and reduce the insulation effect. Utility Model Content

[0004] This utility model provides a building insulation curtain wall that solves the problems of poor installation stability, easy detachment, poor insulation effect, and poor waterproof and fireproof effect of traditional metal plate curtain wall insulation layers.

[0005] This utility model provides a building thermal insulation curtain wall, including a curtain wall body, an insulated wall on the front of the curtain wall body, a keel steel frame on the outside of the insulated wall, a metal panel on the outside of the keel steel frame, the insulated wall being assembled from multiple insulation boards, and two horizontal positioning plates at the upper and lower ends of each insulation board, each positioning plate being connected to a positioning component on the side wall of the curtain wall body.

[0006] Furthermore, the positioning component includes a fixing plate, pre-embedded screws, and fixing nuts. An installation groove is provided on the side wall of the curtain wall body, and multiple pre-embedded screws are fixedly installed in the installation groove. Multiple bolt holes are provided on the fixing plate. Each pre-embedded screw passes through the corresponding bolt hole and the fixing plate is fixed in the installation groove by the fixing nut. The positioning plate extends into the installation groove and is welded and fixedly connected to the fixing plate.

[0007] Furthermore, the outer end face of the positioning plate is provided with a threaded hole, a positioning screw is provided in the threaded hole, and a limiting plate is sleeved on the positioning screw.

[0008] Preferably, a first heat insulation board is provided between two vertically adjacent heat insulation boards, and two second heat insulation boards are provided on both sides of each heat insulation board. The heat insulation board is made of PVC, and the heat insulation board is made of polyurethane composite board.

[0009] Furthermore, the keel steel frame includes keel vertical beams and keel horizontal beams. Two adjacent keel vertical beams are connected by multiple keel horizontal beams. Each keel vertical beam is connected to each of the positioning plates in the same vertical direction. Two limiting plates are provided at the outer end of each positioning plate. The keel vertical beam is fixed between the two limiting plates by bolts.

[0010] Preferably, sound insulation cotton, waterproof cloth, and fireproof layer are sequentially arranged on the outer wall of each insulation board, and waterproof adhesive strips are arranged in the joint between two adjacent insulation boards.

[0011] As can be seen from the above technical solutions, this utility model provides a building insulation curtain wall. Compared with the prior art, the beneficial effects of this utility model are: 1. The insulation board is fixed to the side of the curtain wall body using positioning plates. The keel steel frame is fixed to the outside of the insulation wall using positioning plates. The metal panel is stably supported by the keel steel frame. The insulation wall, keel steel frame, and metal panel are stably fixed to the side of the curtain wall body using positioning plates and positioning components. The insulation board has good installation stability, which can prevent the insulation board from falling off, increase the service life of the insulation board, and the curtain wall body has good insulation effect and safety. 2. The sound insulation cotton, waterproof cloth, fireproof layer, and thermal insulation board are restrained to the side of the curtain wall body by the limiting disc on the positioning screws, preventing the thermal insulation board, sound insulation cotton, waterproof cloth, and fireproof layer from falling off. The sound insulation cotton can reduce external noise, the waterproof cloth can waterproof the curtain wall body and prevent deformation and damage when the curtain wall body is subjected to external forces, and the waterproof strip can enhance the waterproof function of the waterproof cloth. In the event of a fire, the fireproof layer can isolate the thermal insulation board, sound insulation cotton, and waterproof cloth.

[0012] 3. By installing a first insulation board and a second insulation board around the insulation board, heat loss within the building can be effectively reduced, and fires caused by excessively high local temperatures of the insulation board can be prevented. Attached Figure Description

Detailed Implementation

[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] Example 1: See Figure 1-5 A building insulation curtain wall includes a curtain wall body 1, an insulation wall 2 on the front of the curtain wall body 1, a steel frame 3 on the outside of the insulation wall 2, and a metal panel 4 on the outside of the steel frame 3. The insulation wall 2 is assembled from multiple insulation boards 21. Each insulation board 21 has two horizontal positioning plates 22 at its upper and lower ends. Each positioning plate 22 is connected to a positioning component 23 on the side wall of the curtain wall body 1. The positioning plates 22 fix the insulation board 21 to the side of the curtain wall body 1, fix the steel frame 3 to the outside of the insulation wall 2, and stably support the metal panel 4. The insulation wall 2, steel frame 3, and metal panel 4 are stably fixed to the side of the curtain wall body 1 by the positioning plates 22 and positioning components 23. The insulation board has good installation stability, prevents the insulation board from falling off, increases the service life of the insulation board, and the curtain wall body 1 has good insulation effect.

[0018] For details, see Figure 4 , 5The positioning component 23 includes a fixing plate 231, pre-embedded screws 232, and fixing nuts 233. An installation groove 11 is provided on the side wall of the curtain wall body 1. Four pre-embedded screws 232 are fixedly installed in the installation groove 11. One end of each pre-embedded screw 232 is fixed in the concrete of the curtain wall body 1, and the other end extends into the installation groove 11. The fixing plate 231 is vertically installed in the installation groove 11. Multiple bolt holes are provided on the fixing plate 231. Each pre-embedded screw 232 passes through the corresponding bolt hole and the fixing plate 231 is fixed in the installation groove 11 by fixing nuts 233. The positioning plate 22 extends into the installation groove 11 and is welded and fixedly connected to the fixing plate 231.

[0019] For details, see Figure 4 , 5 A horizontal threaded hole is provided in the middle of the outer end face of the positioning plate 22. A positioning screw 24 is provided in the threaded hole. A limiting plate 25 is fitted on the positioning screw 24. The positioning screw 24 is an internal hexagon screw. The limiting plate 25 on the positioning screw 24 can restrict the insulation board 21 to the side of the curtain wall body 1 to prevent the insulation board 21 from falling off. The positioning screw 24 is threadedly connected to the threaded hole on the positioning plate 22. On the one hand, compared with the traditional dovetail nail that penetrates the insulation board 21 and enters the curtain wall body 1 to fix the insulation layer, it is not necessary to pierce the insulation board 21, and the structure of the insulation board 21 will not be damaged. The fixed insulation board 21 has better stability.

[0020] Preferably, see Figure 2 A first heat insulation board 26 is fixedly installed in the gap between two vertically adjacent heat insulation boards 21, and two second heat insulation boards 27 are fixedly installed on both sides of each heat insulation board 21. The heat insulation board 21 is made of PVC, and the heat insulation board 26 is made of polyurethane composite board. By setting the first heat insulation board 26 and the second heat insulation board 27 around the heat insulation board 21, the heat loss in the building can be effectively reduced, and the local temperature of the heat insulation board 21 can be prevented from becoming too high and causing a fire.

[0021] For details, see Figure 1 , 2 The keel steel frame 3 includes keel vertical beams 31 and keel horizontal beams 32. Adjacent keel vertical beams 31 are connected by multiple keel horizontal beams 32. Each keel vertical beam 31 is connected to each positioning plate 22 in the same vertical direction. Two limiting plates 33 are provided at the outer end of each positioning plate 22. The keel vertical beam 31 is fixed between the two limiting plates 33 by bolts. Specifically, the keel vertical beam 31 includes multiple segmented vertical beams. Adjacent segmented vertical beams are connected by connecting beams. The upper and lower ends of the connecting beams are inserted into the interiors of the adjacent segmented vertical beams for positioning and fixing. The connecting beams are fixedly connected to the two limiting plates 33 by bolts.

[0022] Preferably, see Figure 3Each insulation board 21 has a sound insulation cotton 211, a waterproof cloth 212, and a fireproof layer 213 sequentially installed on its outer wall. The sound insulation cotton 211 is made of polyester fiber, and the waterproof cloth 212 is made of polyvinyl chloride (PVC) waterproof cloth. A waterproof adhesive strip 214 is installed in the joint between two adjacent insulation boards 21. The sound insulation cotton 211, waterproof cloth 212, and fireproof layer 213 are glued and fixed to each other with adhesive or other bonding materials. The sound insulation cotton 211, waterproof cloth 212, and fireproof layer 213 are sequentially fixed to the outer surface of the insulation board 21. Finally, the sound insulation is secured by the limiting plate 25 on the positioning screw 24. The insulation board 211, waterproof cloth 212, fireproof layer 213, and insulation board 21 are confined to the side of the curtain wall body 1 to prevent the insulation board 21, sound insulation cotton 211, waterproof cloth 212, and fireproof layer 213 from falling off. The sound insulation cotton 211 can reduce noise from outside the building. The waterproof cloth 212 can waterproof the curtain wall body and prevent the curtain wall body from deforming and being damaged when subjected to external forces. The waterproof strip 214 can increase the waterproof function of the waterproof cloth 212. In the event of a fire, the fireproof layer 213 can isolate the insulation board 21, sound insulation cotton 211, and waterproof cloth 212.

[0023] Optionally, the surface of the metal panel 4 is coated with anti-corrosion paint to prevent the metal panel 4 from being corroded by rainwater.

[0024] In the application of this utility model, firstly, an installation groove 11 is opened on the outer side wall of the curtain wall body 1. Then, holes are drilled in the installation groove 11, and pre-embedded screws 232 are inserted into the drilled holes for fixation. Then, the fixing plate 231 is fixed in the installation groove 11 by fixing nuts 233. Next, the positioning plate 22 is welded and fixedly connected to the fixing plate 231. Then, the insulation board 21 is attached to each positioning plate 22 and fixed to the curtain wall body 1. Then, sound insulation cotton 211, waterproof cloth 212, and fireproof layer 213 are fixedly installed on the outer side of each insulation board 21. At the same time, the first heat insulation board 26 and the second heat insulation board 26 are fixed to the bottom and sides of each insulation board 21. The positioning plate 27 is then inserted into the threaded hole on the outer end face of the positioning plate 22 by the positioning screw 24. The sound insulation cotton 211, waterproof cloth 212, fireproof layer 213, and heat insulation board 21 are fixed and restricted to the side of the curtain wall body 1 by the limiting plate 25. After the heat insulation construction is completed, two limiting plates 33 are welded and fixed on the outer end face of the positioning plate 22. The keel vertical beam 31 is fixedly connected to the two limiting plates 33 by bolts, and the keel horizontal beam 32 is welded and connected between two adjacent keel vertical beams 31. After the keel steel frame 3 is installed, the metal panel 4 is finally fixed on the outside of the keel steel frame 3. The curtain wall has good heat insulation effect, stable structure, and good safety.
