Technical Field
[0001] The present invention relates to the field of building technology and the field of passive door and window thermal bridge breaking structures, and in particular to a passive door and window thermal bridge breaking structure of a perlite composite board system. Background Art
[0002] Perlite insulation composite panels are widely used in various construction fields and are a promising and growing industry. The dominant use of perlite mines at home and abroad is to produce expanded perlite and its products. At present, the annual output of perlite exterior wall insulation panels in my country has exceeded 6 million m 3 , accounting for approximately 7% of my country's annual insulation production, making it the most widely used lightweight insulation material in China. However, due to its material properties, it is prone to water seepage and airtightness issues at the interface with passive doors and windows. Furthermore, due to the more complex thermal insulation structure of passive doors and windows, the quality of passive doors and windows is generally much higher than that of ordinary doors and windows, and therefore the load-bearing capacity requirements of the wall are also higher. The strength of existing perlite insulation composite panels is generally not enough to directly meet the requirements of passive door and window installation.
[0003] Therefore, a passive door and window thermal bridge breaking structure of a perlite composite board system with simple structure, reasonable design, energy saving and high efficiency is invented. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems of fixing and thermal bridge breaking of the passive door and window installation structure of the above-mentioned perlite composite panel system, and provide a passive door and window thermal bridge breaking structure with simple structure and reasonable design, which can also solve the problems of water seepage and airtightness at the junction of the perlite composite panel system door and window and the exterior wall. Specifically, it is a passive door and window thermal bridge breaking structure of the perlite composite panel system.
[0005] The technical solution of the present invention is achieved through the following measures: a passive thermal bridge structure for doors and windows using a perlite composite panel system, wherein steel columns are pre-embedded at the upper and lower openings of the window of the perlite thermal insulation composite panel, a sub-frame is fixed to the steel columns, and a layer of U-shaped mesh is placed on the outer side of the perlite thermal insulation composite panel when plastering to reduce the risk of cracking at the upper and lower openings of the window in the future. The gap between the sub-frame and the window frame is filled with foamed polyurethane, a waterproof vapor-permeable membrane is attached between the outer side of the window and the perlite thermal insulation composite panel, and a waterproof vapor-blocking membrane is attached between the inner side of the window and the perlite thermal insulation composite panel, one end of which is attached to the window frame and the other end is attached to the perlite thermal insulation composite panel; the junction between the window frame and the perlite thermal insulation composite panel is tightly sealed with sealant; a finished drip line is formed at the lower end of the outer side of the perlite thermal insulation composite panel; a finished window sill is installed on the outer side of the window lower opening, the finished window sill is flanged on three sides, and a pre-compression expansion sealing strip is pre-installed on the outermost end of the finished window sill during installation; and an indoor window sill is installed on the indoor side of the window lower opening.
[0006] The perlite thermal insulation composite board is a Class A fireproof composite thermal insulation board, with a layer of galvanized steel wire mesh on each of the left and right sides, followed by a perlite board of a certain thickness, and a polystyrene board on the innermost side.
[0007] The sub-frame is a high-strength solid wood sub-frame with high strength and good thermal insulation effect.
[0008] The technical solution of the present invention has the following positive effects: the pre-embedded steel columns in the perlite thermal insulation composite panels solve the problem that traditional perlite thermal insulation composite panels cannot be installed with passive doors and windows due to insufficient strength; and the doors and windows and the indoor and outdoor sides of the perlite thermal insulation composite panels are sealed inside and outside with two adhesive airtight films, which can well ensure that the building's airtightness meets the requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION
[0010] like Figure 1 As shown, a passive door and window thermal bridge breaking structure of a perlite composite board system includes a steel column 1, a U-shaped net 2, a finished product drip line 3, a waterproof vapor permeable membrane 4, a sealant 5, a perlite thermal insulation composite board 6, a sub-frame 7, a waterproof vapor barrier membrane 8, a foamed polyurethane 9, a pre-pressed expansion sealing tape 10, a finished window sill 11, and an indoor window sill 12. Steel columns 1 are pre-embedded at the upper and lower openings of the window of the perlite thermal insulation composite board 6, and the sub-frame 7 is fixed on the steel column 1. A layer of U-shaped net 2 is placed when plastering the outer side of the perlite thermal insulation composite board 6. The gap between the sub-frame 7 and the window frame is filled with foamed polyurethane 9. The outer side of the window is connected to the window frame. A waterproof vapor-permeable membrane 4 is pasted between the perlite thermal insulation composite panels 6, and a waterproof vapor-blocking membrane 8 is pasted between the inner side of the window and the perlite thermal insulation composite panel 6, one end of which is pasted on the window frame and the other end is pasted on the perlite thermal insulation composite panel 6; the junction between the window frame and the perlite thermal insulation composite panel 6 is tightly sealed with a sealant 5; the lower end of the outer side of the perlite thermal insulation composite panel 6 is made into a finished drip line 3; a finished window sill 11 is installed on the outdoor side of the window bottom opening, and the finished window sill 11 is flanged on three sides. A pre-compression expansion sealing belt 10 is set in advance at the outermost end of the lower side of the finished window sill 11 when installing; an indoor window sill 12 is installed on the indoor side of the window bottom opening.
[0011] Placing a layer of U-shaped mesh 2 on the outside of the perlite thermal insulation composite board 6 when plastering can effectively reduce the cracking problem of the upper and lower openings of the windows in the later stage;
[0012] The gap between the sub-frame 7 and the window frame is filled with foamed polyurethane 9 to prevent indoor and outdoor air from convecting through the tiny gap and causing the risk of condensation indoors;
[0013] The lower end of the outer side of the perlite thermal insulation composite board 6 is made into a finished drip line 3 to prevent water such as rainwater from entering the interior of the building, protect the perlite thermal insulation composite board 6 from rainwater erosion, and prevent the perlite thermal insulation composite board 6 from moisture, leakage and mold;
[0014] The pre-compression expansion sealing strip 10 is installed at the outermost end of the lower side of the finished window sill 11. The pre-compression expansion sealing strip 10, due to its unique expansion performance, can generate pressure between the window sill after installation, thereby achieving a sealing effect. This can effectively prevent problems such as water leakage, wind blowing, and noise during use of the building.
[0015] A waterproof vapor-permeable membrane 4 is pasted between the outside of the window and the perlite thermal insulation composite board 6, and a waterproof vapor-blocking membrane 8 is pasted between the inside of the window and the perlite thermal insulation composite board 6; the two airtight films can reduce the air exchange between indoor and outdoor, and the airtight film can prevent outdoor pollutants from entering the room, while reducing moisture penetration, thereby improving indoor air quality and preventing moisture problems;
[0016] The steel columns 1 are pre-embedded at the upper and lower openings of the window of the perlite thermal insulation composite panel 6, and the sub-frame 7 is fixed on the steel columns 1, and then the doors and windows are fixed to the sub-frame 7. Firstly, by pre-embedding the steel columns 1 at the upper and lower openings of the window of the perlite thermal insulation composite panel 6 in advance, the problem of insufficient strength of the perlite thermal insulation composite panel 6 making it difficult to install passive doors and windows is solved. Secondly, the sub-frame 7 is installed before the doors and windows are installed, which can effectively protect the doors and windows from the impact of subsequent decoration construction and extend their service life.
