Description

Technical Field

[0001] This invention relates to the field of civil engineering technology, and in particular to an airtight adjustable thermal insulation structure and method for connecting prefabricated composite walls with thermally broken doors and windows. Background Technology

[0002] Prefabricated passive buildings, with their advantages of rapid construction and energy efficiency, are gradually becoming a key development direction in the industry. Passive windows and doors, as an important component of buildings, are crucial influencing building energy efficiency and indoor environmental quality due to their airtightness.

[0003] Currently, the installation of prefabricated composite wall doors and windows mostly employs two airtightness measures, similar to external insulation structures: sealing with sealant on the exterior and caulking with elastic materials on the interior. For passive buildings, airtightness requirements are even higher, leading to the development of three- or four-layer composite airtightness designs. However, these designs often involve adding an airtight membrane at the same location where existing airtight measures already exist at the connection between the door / window frame and the wall. A true three-layer airtight structure design adds sealing material between the door / window frames, resulting in even better airtightness. However, due to improper construction or subsequent degradation of airtightness, it is difficult to repair and is therefore rarely used. Summary of the Invention

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0035] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides an airtight adjustable thermal insulation structure for connecting prefabricated composite walls and thermally broken doors and windows. It includes a composite wall body 1, an assembly groove 101 on the composite wall body 1, a fixing base 3 in the assembly groove 101, and a door and window body 2 installed on the fixing base 3.

[0036] The fixed base 3 is provided with an installation groove 301 on the side facing the door and window body 2. The installation groove 301 is provided with a heat insulation component 4, and the heat insulation component 4 is sealed and fitted to the bottom of the door and window body 2.

[0037] The mounting slot 301 is also equipped with a built-in adjustment component 5, which is connected to the insulation component 4 and is used to adjust the sealing tightness of the insulation component 4.

[0038] In summary, when the airtightness does not meet the requirements or needs to be increased during construction or operation, the inflatable insulation component 4 can be inflated to improve airtightness, thus strengthening airtightness measures without removing doors and windows. This extends the repair time for door and window airtightness measures to some extent and reduces operating costs.

[0039] like Figure 4 As shown, in one optional embodiment: the thermal insulation component 4 includes an inflatable sealing tube 403, which is disposed in the mounting groove 301; a silicone rubber sealing strip 402 is disposed on the outer periphery of the sealing tube 403, and a memory foam strip 401 is disposed on the side of the silicone rubber sealing strip 402; both the silicone rubber sealing strip 402 and the memory foam strip 401 are configured to fit tightly against the bottom of the door and window body 2.

[0040] Specifically, an inflatable, sealed rubber tube 403 is used to expand and press the gap between the fixed base 3 and the door / window body 2. A memory foam strip 401 is used, which can automatically return to its original shape after being compressed, and maintain the sealing effect for a long time. It can be dynamically adjusted according to factors such as indoor and outdoor air pressure difference and temperature changes. A silicone rubber sealing strip 402 is used to ensure the airtightness of the gap between the fixed base 3 and the door / window body 2.

[0041] like Figure 4 As shown, as an optional embodiment, the sealing tube 403 is configured to expand in an inflated state to increase the sealing and compression effect on the gap between the door / window body 2 and the composite wall 1.

[0042] Specifically, ensure the airtightness between the main body of the door and window 2 and the composite wall 1.

[0043] like Figure 4 As shown, as an optional embodiment, the memory foam strip 401 is made of memory foam material that can automatically recover its shape after being compressed.

[0044] It is worth noting that the memory foam material is prepared by reacting an amino-based epoxy foam blowing agent, isophorone diamine, and epoxidized tung oil anhydride, wherein the mass ratio of the amino-based epoxy foam blowing agent, isophorone diamine, and epoxidized tung oil anhydride is 1-3:3-4:10-13.

[0045] Specifically, it can automatically return to its original shape after being compressed, and maintain a long-term sealing effect by dynamically adjusting according to factors such as indoor and outdoor air pressure differences and temperature changes to achieve the best airtight effect.

[0046] like Figure 4 As shown, as an optional embodiment, the built-in adjustment component 5 includes an inflatable bladder 502 and an air guide tube 501. The inflatable bladder 502 is installed in the mounting groove 301, and the air guide tube 501 is connected between the exhaust port of the inflatable bladder 502 and the sealing tube 403 for introducing the gas in the inflatable bladder 502 into the sealing tube 403.

[0047] Specifically, when the airbag 502 is pressed, the airbag 502 guides the gas into the sealing tube 403 through the air guide tube 501, thereby inflating the sealing tube 403. This causes the sealing tube 403 to compress the silicone rubber sealing strip 402, thereby ensuring that the silicone rubber sealing strip 402 and the memory foam strip 401 are in full contact with the door and window body 2.

[0048] like Figure 4 As shown, in one optional embodiment, the built-in adjustment assembly 5 further includes a rotating shaft 506 with a cross groove, a reciprocating cam 504, an adjustment seat 505, and an adjustment plate 503. The rotating shaft 506 is rotatably mounted in the mounting groove 301. The reciprocating cam 504 is fixedly sleeved on the rotating shaft 506. The adjustment seat 505 slides with the contour of the reciprocating cam 504 and can reciprocate in the vertical direction under its drive. The adjustment plate 503 is mounted on the adjustment seat 505 and is set corresponding to the airbag 502 for reciprocating pressing of the airbag 502 when the adjustment seat 505 moves.

[0049] Specifically, first, adjust the rotating shaft 506 so that the rotating shaft 506 drives the reciprocating cam 504 to rotate, so that the reciprocating cam 504 drives the adjusting plate 503 to move back and forth in the vertical direction through the adjusting seat 505, so that the reciprocating adjusting plate 503 repeatedly presses the inflatable bag 502.

[0050] like Figure 2As shown, in one optional embodiment: the upper end face of the fixed base 3 is respectively recessed with an adjustment hole 302 and an exhaust hole 303. The inner side wall of the adjustment hole 302 is rotatably engaged with the top end of the rotating shaft 506, and the inner side wall of the exhaust hole 303 is connected to the air inlet pipe provided on the inflatable bladder 502.

[0051] Specifically, the rotating shaft 506 is set inside the adjustment hole 302 to facilitate the adjustment of the rotating shaft 506, and the vent hole 303 is provided for replenishing air to the inflatable bladder 502.

[0052] like Figure 4 As shown, as an optional embodiment, an installation plate 6 is also provided in the installation groove 301, and the installation plate 6 is fixed to the memory foam strip 401 by a snap-fit ​​structure provided thereon.

[0053] Specifically, this facilitates the fixing of the memory foam strip 401.

[0054] like Figure 4 As shown, in one optional embodiment, the memory foam strip 401 has multiple through holes 404, and the mounting plate 6 has multiple threaded holes. Fasteners can pass through the through holes 404 and connect with the threaded holes to help fix the memory foam strip 401 and the door and window body 2.

[0055] Specifically, it facilitates the fasteners to pass through the bottom of the door / window body 2 and the through hole 404 to the threaded hole on the mounting plate 6 for threaded connection, so as to achieve the installation and fixation of the door / window body 2.

[0056] An airtight adjustable thermal insulation structure and method for connecting prefabricated composite walls and thermally broken doors and windows includes the following steps:

[0057] Step S1: Open an assembly groove 101 on the precast composite wall 1 that matches the size of the fixing base 3;

[0058] Step S2: Install and fix the fixing base 3 in the assembly slot 101;

[0059] Step S3: Install the insulation component 4 and the built-in adjustment component 5 into the mounting slot 301 of the fixed base 3, and ensure that the built-in adjustment component 5 and the insulation component 4 are effectively connected;

[0060] Step S4: Install the door and window body 2 onto the fixed base 3, and initially fix it by connecting it with the threaded holes on the mounting plate 6 using fasteners;

[0061] Step S5: Operate the built-in adjustment component 5 to adjust the sealing state of the insulation component 4, so that it applies pressure evenly around the perimeter of the door and window body 2 to form a continuous airtight barrier.

[0062] Step S6: Apply silicone weather-resistant sealant to the joints between the main body 2 of the door and window and the fixed base 3, and between the fixed base 3 and the composite wall 1.

[0063] Step S7: After installation, perform an airtightness test, and make fine-tuning of the seal at specific locations using the built-in adjustment component 5 based on the test results.
