Description

Technical Field

[0001] This utility model relates to the technical field of building insulation structures, specifically a large-mold built-in external wall insulation structure. Background Technology

[0002] With the continuous development of modernization, adding insulation boards to the exterior walls of buildings is very important. In summer, insulation boards can insulate against the outside temperature, keeping the interior temperature constant. In winter, they also insulate against the cold outside air, maintaining a constant interior temperature. Adding insulation boards to the exterior of buildings can improve the comfort of living, reduce energy waste, and make the environment more low-carbon and environmentally friendly.

[0003] Large-formwork built-in external wall insulation systems are a common type of building insulation system. By using pre-embedded anchors or wire mesh frames to cast the insulation board into the concrete wall in a single pour, a composite insulation structure is formed. This avoids the risks of hollowing and detachment associated with traditional external insulation layers. Furthermore, the insulation board and concrete are tightly bonded, resulting in excellent seismic performance and adaptability to structural deformation requirements in high-rise buildings and high wind pressure environments. However, existing large-formwork built-in external wall insulation systems typically use obliquely inserted wire mesh frames to fix the insulation layer to the concrete layer. This fixing method still carries a certain risk of detachment, and during concrete pouring, the concrete may impact the connecting rods, causing the insulation layer to shift and ultimately resulting in uneven external walls. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a large-formwork built-in external wall insulation structure to solve the problem that the current large-formwork built-in external wall insulation structure may cause the insulation layer to fall off or shift during concrete pouring.

[0005] The technical solution adopted by this utility model is a large-formwork built-in external wall insulation structure, including an outer formwork, an inner formwork, and an insulation layer and a concrete pouring layer located between the outer formwork and the inner formwork. A connecting component is connected to the insulation layer, the connecting component penetrates the concrete pouring layer, and the end of the connecting component abuts against the inner formwork.

[0006] The above structure has the following beneficial effects:

[0007] 1. The connecting component runs through the entire concrete pouring layer, which can increase the connection area between the connecting component and the concrete pouring layer, thereby making the connection between the insulation layer and the concrete pouring layer more reliable and stable, and reducing the risk of the insulation layer falling off the concrete pouring layer.

[0008] 2. The connection between the end of the connecting component and the inner formwork allows the connecting component and the insulation layer to be supported by the inner formwork during pouring, so that the insulation layer and the connecting component will not be displaced due to the impact of concrete during pouring, and the insulation layer will remain flat after the concrete is poured.

[0009] Preferably, the connecting assembly includes an "L"-shaped connecting steel bar and a connector for fixing the connecting steel bar. The connector is a cylindrical sleeve, and a limiting end is provided at the end of the connector facing the outer template.

[0010] The setting of the limiting end can limit the position between the connector and the insulation layer, so that the limiting end is tightly attached to the side of the insulation layer. At the same time, the "L" shape of the connecting steel bar can also limit the position by the mutual abutment between the bent section of the connecting steel bar and the limiting end, thereby making the connection between the connector and the insulation layer stable.

[0011] Preferably, the limiting end has a first groove.

[0012] The first groove opened on the limiting end can be used to accommodate the bent end of the connecting steel bar, preventing the connecting steel bar from protruding on the limiting end, and making it easier to apply a mortar leveling layer or decorative layer to the outside of the insulation layer later.

[0013] Preferably, the insulation layer has a second groove for accommodating the limiting end.

[0014] The second groove has the same dimensions as the limiting end, allowing the limiting end to be fitted into the second groove and ensuring that there are no protrusions on the outer surface of the insulation layer. This further facilitates the subsequent application of a mortar leveling layer or decorative layer to the outside of the insulation layer.

[0015] Preferably, the connecting assembly further includes a foot pad installed at the end of the connecting steel bar.

[0016] Foot pads can cover the ends of the connecting steel bars, preventing the connecting steel bars from transferring external heat into the room and thus creating thermal bridging.

[0017] Preferably, the connecting steel bar is also connected to an adjusting rod, the end of the connecting steel bar is provided with an external thread, and the adjusting rod is provided with an internal thread for connecting with the external thread.

[0018] The length of the connecting steel bar can be adjusted by connecting the adjusting rod, so as to flexibly adjust the length of the connecting component according to the thickness of the concrete pouring layer, ensuring that the end of the connecting component can stably abut against the inner formwork. At the same time, the connecting steel bar and the adjusting rod are connected by threads, and the length of the connecting component can be adjusted more flexibly by adjusting the screwing in of the threads.

[0019] Preferably, the outer side of the connector is frustum-shaped, and the diameter of the end of the connector away from the limiting end is smaller than the diameter of the end of the connector near the limiting end.

[0020] The frustum-shaped connector can be inserted into the insulation layer more easily, reducing labor intensity.

[0021] Preferably, the outer side of the connector is provided with a plurality of first limiting protrusions, and the side of the first limiting protrusion away from the limiting end is an inclined surface.

[0022] The first limiting boss allows the connector to be inserted into the insulation layer, preventing the connector from easily detaching from the first limiting boss. At the same time, the side of the first limiting boss away from the limiting end is inclined, which also allows the connector to be easily inserted into the insulation layer. This ensures both convenient and quick construction and a stable connection.

[0023] Preferably, a second limiting boss is provided in the second groove, and the side of the second limiting boss away from the second groove is an inclined surface.

[0024] The second limiting boss can limit the bent end of the connecting steel bar, preventing the connecting steel bar from easily leaving the second groove, further ensuring the safe and stable connection between the connecting steel bar and the connector, thereby improving the connection stability between the insulation layer and the concrete pouring layer; at the same time, the upper surface of the second limiting boss is inclined, which can also guide the bent end of the connecting steel bar, so that the bent end of the connecting steel bar can smoothly enter the second groove.

[0033] The components include: outer formwork 11, inner formwork 12, insulation layer 20, second groove 21, concrete pouring layer 30, connecting component 40, connecting steel bar 41, bending end 411, connector 42, limiting end 421, first groove 422, first limiting boss 423, second limiting boss 424, locking plate 43, foot pad 44, adjusting rod 45, locking nut 46, and wire mesh frame 50. Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] According to the instruction manual Figure 1-3 As shown, this utility model provides a large-formwork built-in external wall insulation structure, including an outer formwork 11, an inner formwork 12, and an insulation layer 20 and a concrete pouring layer 30 located between the outer formwork 11 and the inner formwork 12. The insulation layer 20 is also equipped with a connecting component 40 for connecting the insulation layer 20 and the concrete pouring layer 30. The end of the connecting component 40 penetrates the concrete pouring layer 30 and abuts against the inner formwork 12.

[0037] The connector 42 includes a connector 42 and an "L"-shaped connecting steel bar 41. The connector 42 is a cylindrical sleeve, and a limiting end 421 is provided at the end of the connector 42. The limiting end 421 is flared and is used to abut against the outer side of the insulation layer 20. The connecting steel bar 41 is inserted in the middle of the connector 42, and the "L"-shaped bent end 411 of the connecting steel bar 41 abuts against the limiting end 421. The end of the connector 42 away from the limiting end 421 is also connected to a locking disc 43 by a thread. The locking disc 43 abuts against the inner side of the insulation layer 20. A foot pad 44 is also installed at the end of the connecting steel bar 41. In this embodiment, the foot pad 44 is made of plastic. The foot pad 44 can effectively isolate heat from being transferred through the connecting steel bar 41 and reduce the thermal bridging effect.

[0038] In this embodiment, a first groove 422 for accommodating the bent end 411 of the connecting steel bar 41 is also provided on the limiting end 421. The first groove 422 is a rectangular groove, and the bent end 411 of the connecting steel bar 41 can be embedded in the first groove 422. At the same time, a second groove 21 for accommodating the limiting end 421 is also provided on the insulation layer 20. The shape and size of the second groove 21 are the same as those of the limiting end 421. With the setting of the first groove 422 and the second groove 21, the bent end 411 of the connecting steel bar 41 is hidden in the first groove 422. At the same time, the connector 42 is hidden in the insulation layer 20 through the second groove 21. This allows the outer side of the insulation layer 20 to be tightly attached to the outer template 11. On the one hand, this ensures that the insulation layer 20 remains flat under the limiting of the outer template 11. On the other hand, it also facilitates the subsequent application of a mortar leveling layer or a decorative layer on the outer side of the insulation layer 20.

[0039] Several first limiting protrusions 423 are also provided on the outer side of the connector 42. The outer surface of the first limiting protrusion 423 is a slope, and the side of the first limiting protrusion 423 facing the limiting end 421 is a limiting surface, so that the cross section of the first limiting protrusion 423 is triangular, thereby enabling the connector 42 to be smoothly inserted into the insulation layer 20. At the same time, under the action of the limiting surface of the first limiting protrusion 423, the connector 42 will not easily fall off from the insulation layer 20.

[0040] Its working principle is as follows: When installing the large-formwork built-in external wall insulation structure, first insert the connector 42 into the insulation layer 20, so that the limiting end 421 is embedded in the second groove 21 on the insulation layer 20, and connect the locking plate 43 to the connector 42, so that the insulation layer 20 is clamped between the locking plate 43 and the limiting end 421. Then insert the connecting steel bar 41 into the connector 42 and push the bent end 411 into the first groove 422. Then install the inner formwork 12 and make the connecting steel bar 41 abut against the inner formwork 12. After all the connectors 42 of the insulation layer 20 are connected, the outer formwork 11 is installed on the outside of the insulation layer 20. Then the concrete pouring layer 30 can be poured. After the concrete pouring layer 30 is completely solidified, remove the inner formwork 12 and the outer formwork 11 to complete the installation of the large-formwork built-in external wall insulation structure.

[0041] Example 2

[0042] According to the instruction manual Figure 4 As shown, the difference between this embodiment and embodiment 1 is that an adjusting rod 45 is also connected to the end of the connecting steel bar 41 away from the bending end 411, and an external thread is provided at the end of the connecting steel bar 41. At the same time, an internal thread for connecting with the external thread is provided on the adjusting rod 45. In this embodiment, a foot pad 44 is installed at the end of the adjusting rod 45.

[0043] To improve the installation stability of the adjusting rod 45, a locking nut 46 is installed at the external thread of the connecting steel bar 41. The adjusting rod 45 is locked by the locking nut 46 to prevent the adjusting rod 45 from loosening.

[0044] The working principle of this embodiment is that the length of the entire connecting assembly 40 can be adjusted by adjusting the adjusting rod 45 to ensure that the end of the connecting assembly 40 can stably abut against the inner template 12, thereby improving the stability of the connecting assembly 40 during the concrete pouring process.

[0045] Example 3

[0046] According to the instruction manual Figure 5-7 As shown, a second limiting boss 424 is installed in the second groove 21. The second limiting boss 424 is made of elastic plastic material, and the side of the second limiting boss 424 away from the second groove 21 is an inclined surface.

[0047] The working principle of this embodiment is as follows: when connecting the connecting steel bar 41 and the connector 42, the connecting steel bar 41 is inserted into the connector 42, and the bent end 411 of the connecting steel bar 41 is embedded in the second groove 21. The inclined surface of the second limiting boss 424 can guide the connecting steel bar 41. When the connecting steel bar 41 is pushed, the second limiting boss 424 undergoes elastic deformation, thereby allowing the connecting steel bar 41 to enter the gap between the second bosses. The second limiting boss 424 can limit the bent end 411 of the connecting steel bar 41 that has entered the second groove 21, preventing the connecting steel bar 41 from separating from the connector 42.
