Description

Technical Field

[0001] This application relates to the field of curtain wall insulation technology, and in particular to a thermal break insulation system for building curtain walls. Background Technology

[0002] Traditional residential curtain wall insulation systems typically involve installing a layer of insulation board on the wall. The insulation board is made of inorganic lightweight aggregate, which makes it highly brittle.

[0003] When installing insulation boards, the process typically involves first applying a layer of adhesive mortar to the exterior wall surface, then attaching the insulation boards to the mortar. After attachment, a second layer of adhesive mortar is applied to the side of several insulation boards facing away from the wall, connecting them into a single unit. A mesh fabric is then attached over this second layer, and reinforcing nails are driven through the mesh fabric, penetrating the insulation boards and embedding them into the exterior wall. Finally, another layer of mortar is applied over the mesh fabric to complete the insulation board installation. When installing curtain walls, the operator installs a framework on the exterior wall, then installs the curtain wall panels onto the framework, completing the curtain wall insulation system.

[0004] When installing insulation boards, nails need to be driven into the mesh fabric. During nailing, the nails penetrate the insulation board and are embedded within the exterior wall to improve the stability of the insulation board on the exterior wall. However, due to the inherent brittleness of the insulation board, it is prone to cracking and damage during nailing, affecting its performance. Summary of the Invention

[0005] To reduce the problem of cracking during nailing in the installation of insulation boards, which affects their normal use, this application provides a thermal break insulation system for building curtain walls.

[0006] The thermal break insulation system for building curtain walls provided in this application adopts the following technical solution:

[0007] A thermal break insulation system for building curtain walls includes keels for connecting to the wall, a plurality of insulation board modules disposed between two adjacent keels, the insulation board modules being adhered to the wall, a plurality of crossbars detachably disposed between two adjacent keels, the crossbars and the keels forming a receiving groove for accommodating the insulation board modules, a curtain wall panel disposed in each receiving groove, a limiting plate for limiting the position of the curtain wall panel disposed on the crossbars, and a pressure plate for pressing the insulation board modules against the wall disposed on the curtain wall panel.

[0008] By adopting the above technical solution, the operator adheres the insulation board module to the wall and installs horizontal bars on the keel. The horizontal bars and the corresponding keel form a receiving groove, which can limit the position of the insulation board module. The operator installs the curtain wall panel in the receiving groove and uses the pressure plate on the curtain wall panel to press the insulation board module against the wall. On the basis of completing the installation of the curtain wall panel, the insulation board module is further limited, reducing the possibility of damage to the insulation board module when nailing it, which would affect normal use.

[0009] Optionally, the keel is provided with a limiting groove on the side facing the receiving groove, and a protruding rib for inserting into the limiting groove is fixedly connected to the pressure plate. The curtain wall panel is provided with a push plate for preventing the protruding rib from disengaging from the limiting groove on the side facing the wall.

[0010] By adopting the above technical solution, when the operator presses the pressure plate against the insulation board module, the protrusion on the pressure plate is inserted into the limiting groove on the keel to prevent the insulation board module from detaching from the wall. When installing the curtain wall panel, the push plate on the curtain wall panel presses against the pressure plate. While pressing the pressure plate against the insulation board module, it also prevents the protrusion from detaching from the limiting groove. Through the interlocking effect between the protrusion and the limiting groove, the limiting effect on the insulation board module is improved.

[0011] Optionally, a mounting base for fixing the crossbar is fixedly connected to the side wall of the keel. The mounting base can limit the position of the insulation board module. A slot is opened on the side of the mounting base away from the wall, and an insert plate for inserting into the slot is fixedly connected to the crossbar. The insert plate and the crossbar are detachably connected through a connecting unit.

[0012] By adopting the above technical solution, mounting seats are fixedly connected to the opposite surfaces of adjacent keels. When the horizontal bars are not installed, the mounting seats limit the position of the insulation board curtain wall. When installing the horizontal bars, the insert plate is inserted into the slot to achieve the positioning of the horizontal bars. After the insert plate is inserted into the slot, it is fixed by the connecting unit, thereby improving the ease of installation of the horizontal bars between the keels.

[0013] Optionally, the keel has a groove on the side away from the wall, and the curtain wall panel has a folded edge for inserting into the groove.

[0014] By adopting the above technical solution, the folded edges on both sides of the curtain wall panel are inserted into the groove, reducing the occurrence of edge warping of the curtain wall panel.

[0015] Optionally, the keel is provided with a reinforcing plate for pressing the curtain wall panels on both sides, and slots are provided on both sides of the groove. The side of the reinforcing plate facing the keel is provided with a locking block for inserting into the slot.

[0016] By adopting the above technical solution, when installing the reinforcing plate, the clips on the reinforcing plate are inserted into the slots to fix the position of the reinforcing plate on the keel. The reinforcing plate presses the curtain wall panel onto the keel, thereby improving the installation stability of the curtain wall panel on the wall.

[0017] Optionally, two pressure plates are provided in the receiving groove, and the pressure plates in the same receiving groove correspond one-to-one with the keel. A support rod is provided between the two pressure plates. Both ends of the support rod are fixedly connected to end plates for abutting against the pressure plates. A stud is fixedly connected to the pressure plate at the position corresponding to the end plate. A locking groove is opened at the lower end of the end plate for the stud to be inserted. A nut for pressing the end plate is threaded on the stud.

[0018] By adopting the above technical solution, the operator installs pressure plates at the positions corresponding to the two keels in the installation groove. The pressure plates abut against the insulation board module, and the protruding edges are inserted into the limiting grooves. Then, the operator installs a support rod between the two pressure plates, with studs passing through the locking grooves on the end plates and fixed with nuts. The support rod restricts the relative movement of the two pressure plates, ensuring that the protruding edges on both pressure plates remain inserted into the corresponding limiting grooves, thus maintaining the limiting effect of the pressure plates on the insulation board module.

[0019] Optionally, a sleeve is fixedly connected to one end of the nut facing the end plate. The sleeve is fitted onto the stud. A through hole is provided on the end plate for the sleeve to pass through. The diameter of the through hole is larger than the width of the locking groove.

[0020] By adopting the above technical solution, a sleeve is installed on the nut and inserted into the through hole, making it difficult for the stud to come out of the locking groove, thus improving the connection stability between the support plate and the pressure plate.

[0021] Optionally, the support rod is provided with a first snap-fit ​​plate, and a first hook groove is formed between the first snap-fit ​​plate and the support rod. The first hook groove is set upward. A second snap-fit ​​plate is provided on the side of the curtain wall panel facing the wall, and a second hook groove is formed between the second snap-fit ​​plate and the curtain wall panel. The second hook groove is set downward. The first hook groove and the second hook groove can be inserted into each other.

[0022] By adopting the above technical solution, the first hook groove and the second hook groove can be inserted into each other.

[0023] The first and second hook slots can be inserted into each other, thereby improving the stability of the curtain wall panel installation on the wall.

[0024] Optionally, the mounting base is provided with a first positioning groove, and the insert plate is provided with a second positioning groove for aligning with the first positioning groove. The first positioning groove and the second positioning groove form a positioning hole, and a positioning block for inserting into the positioning hole is fixedly connected to the curtain wall panel.

[0025] By adopting the above technical solution, when installing the curtain wall panel, the curtain wall panel is first inserted into the receiving groove so that the positioning hole is aligned with the positioning block. Then, the operator slides the curtain wall panel so that the positioning hole on the curtain wall panel is inserted into the positioning hole. This improves the connection stability between the curtain wall panel and the mounting base, and also improves the connection stability of the crossbar on the mounting base.

[0026] In summary, this application includes at least one of the following beneficial technical effects: the insulation board module is adhered to the wall corresponding to the receiving groove, and then the curtain wall panel is installed. The insulation board module is pressed against the wall by the pressure plate on the curtain wall panel. On the basis of completing the installation of the curtain wall panel, the insulation board module is further limited, reducing the possibility of damage to the insulation board module when nailing it, which would affect normal use.

[0036] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0037] This application discloses a thermal break insulation system for building curtain walls. For example... Figure 1-2 The building curtain wall thermal break insulation system includes several keels 1 fixedly connected to the exterior wall of the building. The cross-section of each keel 1 is rectangular, and each keel 1 is vertically arranged with adjacent keels 1 spaced apart. Several mounting seats 11 are welded and fixedly connected to the opposite surfaces of two adjacent keels 1. The mounting seats 11 on the same side wall of the keel 1 are evenly spaced along the length of the keel 1. The mounting seats 11 on the opposite surfaces of two adjacent keels 1 correspond one-to-one, and a crossbar 13 is detachably fixedly connected between two corresponding mounting seats 11. Two adjacent crossbars 13 and two corresponding keels 1 form a receiving groove 3. An insulation board module 31 is placed in the receiving groove 3 and is adhered to the wall surface by cement mortar. The receiving groove 3 is also provided with a curtain wall panel 33. The curtain wall panel 33 is located on the side of the insulation board module 31 away from the wall. The side of the curtain wall panel 33 facing the wall is provided with a pressure plate 32 for pressing against the insulation board module 31. The side of the crossbar 13 away from the wall is fixedly connected with a limiting plate 15 for preventing the curtain wall panel 33 from leaving the receiving groove 3. The limiting plate 15 is located on the side of the curtain wall panel 33 away from the wall, so as to achieve the effect of fixing the curtain wall panel 33.

[0038] like Figure 2-3The mounting base 11 has a slot 12 on the side facing away from the wall, and a plate 14 for inserting into the slot 12 is fixedly connected to the crossbar 13. The mounting base 11 is provided with a connecting unit 2 for confining the plate 14 within the slot 12. The connecting unit 2 includes a tube 21. Both the mounting base 11 and the plate 14 have insertion holes 22 for inserting the tube 21. When the plate 14 is inserted into the slot 12, the insertion holes 22 on the mounting base 11 are aligned with the insertion holes 22 on the plate 14, and the tube 21 can be directly inserted into each insertion hole 22. One end of the tube 21 is provided with a protruding ring 23 for preventing itself from detaching from the insertion hole 22. The protruding ring 23 abuts against one side of the mounting base 11. A fastening bolt 24 passes through the insertion hole 22 of the mounting base 11 facing away from the protruding ring 23. The fastening bolt 24 is inserted into the tube 21 and threadedly connected to the tube 21, thereby fixing the position of the crossbar 13 on the mounting base 11.

[0039] like Figure 4-5 A limiting strip 35 is fixedly connected to the side of the keel 1 away from the wall. The limiting strip 35 has a wing plate 36 integrally formed along the width direction of the corresponding keel 1, and the wing plate 36 forms a limiting groove 37 with the corresponding keel 1. The two limiting grooves 37 corresponding to the same keel 1 are arranged opposite each other and located on both sides of the width direction of the keel 1, and the length direction of the limiting groove 37 is parallel to the length direction of the keel 1. Two pressure plates 32 are provided in the receiving groove 3. The pressure plates 32 correspond one-to-one with the corresponding keel 1. The pressure plates 32 are long strips with an L-shaped cross-section. The length direction of the pressure plates 32 is parallel to the length direction of the keel 1. The pressure plates 32 are located between the two mounting seats 11 of the corresponding keel 1, and both ends of the pressure plates 32 abut against the side of the corresponding mounting seat 11 facing the receiving groove 3. One of the outer side walls of the pressure plate 32 abuts against the insulation board module 31, and the other outer side wall of the pressure plate 32 abuts against the corresponding keel 1. A protruding rib 34 is fixedly connected to the outer side wall, and the protruding rib 34 is inserted into the limiting groove 37.

[0040] like Figure 2 and Figure 6Multiple support rods 4 are provided between the two pressure plates 32. The length direction of the support rods 4 is parallel to the length direction of the crossbar 13. The multiple support rods 4 are spaced apart along the length direction of the pressure plates 32 in the receiving groove 3. The support rods 4 abut against the inner wall of the pressure plates 32 away from the insulation board module 31. Both ends of the support rods 4 are fixed to the end plates 41 for abutting against the pressure plates 32. The end plates 41 press the pressure plates 32 tightly against the corresponding keel 1 and prevent the protrusions 34 from sliding out of the limiting grooves 37. A stud 42 is vertically fixedly connected to the inner wall of the pressure plate 32 away from the protruding ridge 34. A locking groove 43 is opened at the lower end of the end plate 41 for the stud 42 to pass through. The stud 42 is inserted into the locking groove 43. A nut 44 is threadedly connected to one end of the stud 42 that passes through the locking groove 43. A sleeve 45 is fixedly connected to one end of the nut 44 facing the end plate 41. The sleeve 45 is sleeved on the stud 42. A through hole 46 is opened on the end plate 41 for the sleeve 45 to be inserted. The diameter of the through hole 46 is larger than the groove width of the locking groove 43.

[0041] like Figure 6-8 A first snap-fit ​​plate 5 is fixedly connected to the side of the support rod 4 facing away from the wall. The first snap-fit ​​plate 5 is located above the support rod, and a first hook groove is formed between the first snap-fit ​​plate 5 and the support rod 4, with the opening of the first hook groove facing upwards. A second snap-fit ​​plate 52 is fixedly connected to the side of the curtain wall panel 33 facing the wall. The cross-section of the second snap-fit ​​plate 52 is L-shaped, and a second hook groove is formed between the second snap-fit ​​plate 52 and the curtain wall panel 33, with the opening of the second hook groove facing downwards. The operator can slide the curtain wall panel 33 upwards and downwards, so that the second hook groove and the first hook groove interlock, improving the connection stability of the curtain wall panel 33 on the wall.

[0042] like Figure 8 Two push plates 38 are fixedly connected to the side of the curtain wall panel 33 facing the wall. The push plates 38 are long strips, and the length direction of both push plates 38 is parallel to the length direction of the horizontal bar 13. The sides of the push plates 38 abut against the inner side wall of the pressure plate 32 away from the insulation board module 31, and both ends of the push plates 38 abut against the inner side wall of the corresponding pressure plate 32 away from the keel 1, thereby restricting the movement of the curtain wall panel 33 along the length direction of the horizontal bar 13.

[0043] like Figure 3 and Figure 8A positioning block 6 is fixedly connected to the lower surface of the push plate 38 at the lower end of the curtain wall panel 33. A first positioning groove 61 is opened at the upper end of the mounting base 11, and the first positioning groove 61 is open away from the groove wall of the keel 1. A protrusion 62 is fixedly connected to the upper end of the insert plate 14. When the insert plate 14 is inserted into the corresponding slot 12, the protrusion 62 is located on the side of the mounting base 11 away from the keel 1. A second positioning groove 63 is opened on the protrusion 62, and the second positioning groove 63 is open towards the side of the mounting base 11. When the insert plate 14 is inserted into the corresponding slot 12, the first positioning groove 61 and the second positioning groove 63 are aligned and form a positioning hole for the positioning block 6 to be inserted. The positioning block 6 is inserted into the positioning hole to limit the movement between the crossbar 13 and the mounting base 11, and further improve the connection stability of the crossbar 13 on the mounting base 11.

[0044] like Figure 5 The limiting strip 35 has a groove 7 on the side away from the keel 1. The length direction of the groove 7 is parallel to the length direction of the keel 1. Each of the two groove walls of the groove 7 has a slot 72, and the length direction of the slot 72 is parallel to the length direction of the groove 7. The groove 7 and the slot 72 form a T-shaped sliding groove. The curtain wall panel 33 extends to the corresponding groove 7 on both sides along the length direction of the horizontal bar 13. The curtain wall panel 33 also has a folded edge 71 on both sides along the length direction of the horizontal bar 13, which is embedded in the groove 7 but does not extend to the slot 72. A reinforcing plate 73 is provided on the side of the limiting strip 35 away from the keel 1. The reinforcing plate 73 is located on the side of the curtain wall panel 33 away from the limiting strip 35. Two locking blocks 74 are fixedly connected to the side of the reinforcing plate 73 facing the groove 7 for insertion into the slot 72. The slot 72 and the block 74 work together to fix the position of the reinforcing plate 73 on the limiting strip 35. Since the reinforcing plate 73 is located on the side of the curtain wall panel 33 away from the limiting strip 35, the reinforcing plate 73 limits the curtain wall panel 33 on both sides along the length of the horizontal bar 13, thereby further improving the connection stability of the curtain wall panel 33 on the wall.

[0045] The implementation principle of this application embodiment is as follows: When the operator is carrying out curtain wall construction, first install the keel 1 on the exterior wall of the building. The keel 1 can be fixed to the wall by expansion bolts. Adjacent keels 1 form several receiving grooves 3 under the spacing of the mounting seats 11. The operator installs the insulation board module 31 in the receiving grooves 3. During the installation of the insulation board module 31, the operator first applies cement mortar to one side of the insulation board module 31, and then attaches the insulation board module 31 to the corresponding wall surface in the receiving groove 3. Subsequently, the operator installs the pressure plate 32 in the receiving groove 3, so that the pressure plate 32 is located between the two mounting seats 11 of the same keel 1, and one side of the pressure plate 32 abuts against the insulation wall panel, and the protrusion 34 on the pressure plate 32 is inserted into the limiting groove 37. Then, by installing the support rod 4, the two pressure plates 32 are fixed, and the protrusion 34 on the pressure plate 32 is kept in the state of being inserted into the limiting groove 37, thus achieving the initial fixation of the insulation board module 31.

[0046] Before installing the curtain wall panel 33, the horizontal bar 13 below the curtain wall panel 33 should be installed first. After the horizontal bar 13 is installed, positioning holes are formed at the upper end of the horizontal bar 13 corresponding to the two mounting seats 11. When installing the curtain wall panel 33, the push plate 38 of the curtain wall panel 33 is set towards the receiving groove 3, and the push plate 38 with the positioning block 6 is set downward. The operator inserts the curtain wall panel 33 into the receiving groove 3, so that the two folded edges 71 of the curtain wall panel 33 along the length direction of the horizontal bar 13 are inserted into the groove 7. The push plate 38 abuts against the inner side wall of the pressure plate 32 away from the insulation board, and the second snap-fit ​​plate 52 is located above the corresponding first snap-fit ​​plate 5, and the positioning block 6 is located above the corresponding positioning hole.

[0047] The operator then slides the curtain wall panel 33 downwards, causing the first snap-fit ​​plate 5 and the second snap-fit ​​plate 52 to snap together. The positioning block 6 is inserted downwards into the positioning hole, achieving initial fixation of the curtain wall panel 33 on the wall and completing the final fixation of the insulation board module 31. The operator then installs the horizontal bar 13 at the upper end of the curtain wall panel 33, and uses the limiting plates 15 on the upper and lower horizontal bars 13 to position the curtain wall panel 33, achieving further fixation of the curtain wall panel 33. Finally, the operator inserts the reinforcing plate 73 into the T-shaped groove, so that the reinforcing plate 73 presses the side of the curtain wall panel 33 with the folded edge 71 against the limiting strip 35, achieving the final fixation of the curtain wall panel 33.

[0048] The installation of the insulation board module 31 and the curtain wall is completed in the above manner, avoiding the step of drilling holes in the insulation board module 31, thereby reducing damage to the insulation board and solving the problem that drilling holes in the insulation board causes cracking of the insulation board and affects its normal use.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
