Abstract
Description
Technical Field
[0001] The invention relates to the field of building thermal insulation, and in particular to an installation structure for an ecological plant fiber fire-resistant inner-embedded framed outer window suitable for ultra-low energy consumption buildings. Background Art
[0002] Ultra-low energy buildings improve the thermal insulation performance of the building's exterior envelope, which is a necessary means to reduce building energy consumption. Ultra-low energy buildings can achieve indoor comfort while reducing heating energy consumption by more than 90%, and air conditioning energy consumption in summer by more than three quarters, thereby greatly alleviating the pressure to reduce greenhouse gas emissions. For example, the prior art CN207377454U discloses an embedded venetian blind structure suitable for ultra-low energy buildings with good thermal insulation and good structural properties, including a venetian blind, wherein the venetian blind is a Z-shaped aluminum alloy venetian blind or a rolled venetian blind, and the venetian blind is embedded in the outer insulation layer of the wall through a venetian blind box cover; the lower part of the venetian blind box cover has a venetian blind side rail bracket, and the inner side of the venetian blind side rail bracket has an insulating gasket near the end. The utility model provides an embedded venetian blind structure suitable for ultra-low energy consumption buildings. Through the use of heat insulation gaskets and the pre-compression expansion sealing tape and silicone sealant sealing treatment on the outer insulation layer, the venetian blind structure has better thermal insulation effect and high structural strength. However, there are still some problems in the installation of external windows, which account for more than one-third of the energy consumption in the external enclosure structure: first, there is no Class A flame-retardant embedded auxiliary frame on the market, which causes most passive house projects to adopt external hanging installation, which is complicated in process and high in cost; second, the external windows are installed before the external insulation materials, which makes the external windows very easy to be damaged during the construction process; third, the connection structure between the auxiliary frame and the external windows and window sills of different materials is not universal and inconvenient for construction.
[0003] The ecological plant fiber fire-resistant embedded frame exterior window installation structure provided by this technology solves the above problems. The straw produced by crops in my country every year is one of the important sources of greenhouse gases. Whether the straw is returned to the field as fertilizer or burned, it will produce greenhouse gases such as carbon dioxide and methane. If high-quality panels are produced using straw as raw material, not only will the greenhouse gases produced by the rotting and burning of straw be eliminated, but also high-quality products will be provided to society. The present invention is an ecological plant fiber fire-resistant exterior window frame made of plants such as straw as raw materials. The fireproof grade is not less than B1 and can reach A2. It has small deformation and is waterproof. It can fully meet the requirements of exterior window frames for ultra-low energy consumption buildings. Summary of the invention
[0004] In order to solve the problems existing in the existing practices, the present invention provides an installation structure of an ecological plant fiber fire-resistant embedded frame external window suitable for ultra-low energy consumption buildings, comprising a base wall, an ecological plant fiber fire-resistant embedded frame, an external window, a waterproof vapor barrier film, an insulation layer, a pre-compression expansion sealing tape, an outdoor metal window sill, and fixing screws.
[0005] This construction method realizes the external window frame structure, which can be installed after the insulation project is completed. The inner opening size matches the door and window opening size, and the external window can be replaced and removed without affecting the building's exterior wall structure. Compared with the traditional ultra-low energy consumption building installation method, it not only realizes that the external window can be built into the window opening, but also saves the waterproof breathable membrane, thereby greatly reducing the construction difficulty and construction cost.
[0006] The thermal insulation layer covers to the edge of the attached frame; the pre-compression expansion sealing belt is placed on the light-facing baffle at the overlap of the outer window and the attached frame, and the width of the pre-compression expansion sealing belt is not less than 15mm; the outer window is placed on the inner side of the ecological plant fiber fire-resistant embedded attached frame, and one side of the waterproof vapor barrier membrane is bonded to the outer window and the other side is bonded to the ecological plant fiber fire-resistant embedded attached frame, and the bonding width is not less than 2cm; the window sill is connected to the attached frame by screws.
[0007] Furthermore, the ecological plant fiber fire-resistant auxiliary frame has a combustion performance level of not less than B1, is set by nails or anchors and is placed at the lower part of the outer window with a depth of not less than 12 mm; further, the lower frame of the outer window is extended by more than 12 mm from the auxiliary frame; compared with the existing practice, the present invention has the following beneficial effects:
[0008] 1. The combustion performance level of the ecological plant fiber fire-resistant embedded frame is not less than B1 level and can reach A2 level;
[0009] 2. The fire-resistant embedded frame of ecological plant fiber is moisture-resistant and does not deform;
[0010] 3. The ecological plant fiber fire-resistant embedded frame can be nailed or anchored, easy to cut, and convenient to process on the construction site;
[0011] 4. The compressive strength of the ecological plant fiber embedded fire resistant frame is above 20MPa;
[0012] 5. The ecological plant fiber fire-resistant embedded frame can be precisely processed in the factory, avoiding the difficulty of processing the exterior windows caused by the large error between the door and window opening size and the design size caused by the construction;
[0013] 6. The structure of the outer window, pre-compression expansion sealing strip and attached frame can prevent the intrusion of storm and rainwater;
[0014] 7 The exterior windows can be replaced and removed without affecting the exterior wall structure of the building;
[0015] 8 The window sill can be directly anchored with the ecological plant fiber fire-resistant exterior window frame, solving the problem of difficult fixing and installation of the window sill in the project;
[0016] 9 The ecological plant fiber fire-resistant inner-embedded framed outer window installation structure and construction method avoids the use of traditional waterproof vapor permeable membranes, saving engineering costs;
[0017] 10 The ecological plant fiber frame converts straw into high-performance building materials, playing an important role in reducing CO2 emissions from straw and other plants. BRIEF DESCRIPTION OF THE DRAWINGS
