[0002] In order to achieve the goal of energy conservation and carbon reduction, higher requirements are put forward for the energy-saving efficiency of buildings. However, gaps are often formed between the external doors and windows and the main structure of the current projects, and the air tightness and thermal insulation cannot meet the requirements of ultra-low energy consumption, near-zero energy consumption, and zero energy consumption buildings;

[0003] For example, a door and window installation structure of "CN104314421B" includes a sub-frame and a door and window outer frame, characterized in that the sub-frame is installed on the wall, a jack structure is installed between the sub-frame and the door and window outer frame, and the jack structure applies uniform pressure toward the center around the door and window outer frame to fix it. The door and window installation structure of the present invention does not need to drill holes on the door and window outer frame, which saves the time of drilling process, makes the door and window installation method simpler, makes the up and down and left and right adjustment of the door and window easier, improves the installation accuracy of the door and window, and after the door and window are installed, there are no screw holes in the inner viewing frame, making the door and window more beautiful;

[0004] However, in the prior art, when doors and windows are installed, the gaps between the doors and windows and the main structure are often not sealed tightly, which makes it difficult for the airtightness to meet the requirements of ultra-low energy consumption and near-zero energy consumption buildings. In addition, the commonly used steel auxiliary frames have a large heat transfer coefficient and can easily form cold and hot bridges, causing the thermal insulation performance of the doors and windows to deteriorate, making it impossible to meet the requirements of ultra-low energy consumption and near-zero energy consumption. Summary of the invention

[0005] In view of the above existing problems, the present invention is proposed.

[0006] The purpose of the present invention is to solve the problem in the prior art that when steel auxiliary frames are installed on doors and windows, the heat transfer coefficient is large, a cold and hot bridge is easily formed, and the thermal insulation performance of the doors and windows is deteriorated.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] On the one hand, the present invention provides a low-energy door and window installation structure that can improve air tightness, which includes an installation frame arranged at a designated installation position on the ground, the inner side of the installation frame is used for sealing and assembling connection with the door and window frame, the outer side of the installation frame is used to abut against an outdoor external beam, a floor is arranged above the ground, an insulation board is arranged between the installation frame and the door and window frame, the installation frame is assembled and connected to the door and window frame through expansion bolts, a first waterproof and air-proof membrane is arranged on one side of the installation frame located indoors and on the other side connected to the door and window frame, one side of the first waterproof and air-proof membrane is assembled and connected to the ground, the floor and the bottom of the door and window frame, a second waterproof and air-proof membrane is arranged on one side of the installation frame located outdoors, the second waterproof and air-proof membrane is assembled and connected to the ground and the floor, an airtight layer is arranged between the insulation board and the door and window frame, an L-shaped steel plate is arranged on the ground close to the outdoor side of the installation frame, the L-shaped steel plate is assembled and connected to the ground and the installation frame respectively through fixing nails, and the L-shaped steel plate is located between the floor and the door and window frame.

[0009] Furthermore, the installation frame is an anticorrosive wooden auxiliary frame with a width of 100 mm and adapted to the door and window frame, and the insulation board is a high-strength polyurethane heat-insulating and moisture-proof pad with a thickness of 10 mm. By setting the base installed with the door and window frame to an anticorrosive wood structure, on the one hand, the wood has a good thermal insulation effect, and the indoor and outdoor temperatures are difficult to form a thermal bridge effect through the anticorrosive wood. On the other hand, the excellent corrosion resistance of the anticorrosive wood prolongs the life of the base, and has excellent dimensional stability to prevent deformation of doors and windows. The high-strength polyurethane heat-insulating and moisture-proof pad can further improve the installation effect of doors and windows. It has extremely high compression and bending resistance, low thermal conductivity, only 0.02~0.03W / m·K, is an excellent thermal insulation material, can significantly reduce the thermal bridge effect, the material structure is closed-cell foam, does not absorb water or has an extremely low moisture absorption rate, effectively prevents performance degradation caused by moisture penetration, and the material has good stability.

[0010] Furthermore, the airtight layer and the end surface of the second waterproof and air-blocking membrane are connected by a sealant sealing assembly, and the sealant is located between the inner side of the L-shaped steel plate and the insulation board. The provided sealant is used to seal the airtight layer and the second waterproof and air-blocking membrane.

[0011] Furthermore, the second waterproof and air-blocking membrane is laid on the outer wall of the outer beam, one end of the second waterproof and air-blocking membrane is located on the side of the outer beam close to the installation frame, and the other end extends to the side of the installation frame close to the outdoors and is assembled and connected to the outer side of the L-shaped steel plate. By laying the second waterproof and air-blocking membrane in this way, in combination with the set air-tight layer and sealant, it can be difficult for outdoor water vapor to pass through the sealant, air-tight layer and air-blocking membrane and contact the installation frame.

[0012] Furthermore, the airtight layer includes a sealing layer and an adjusting layer, wherein the adjusting layer is arranged on the inner side of the sealing layer, the adjusting layer is assembled and connected with the mounting frame and the insulation board, the adjusting layer is arranged as a hollow structure, and one end of the adjusting layer is arranged to supply air through an air pump. Through the arranged adjusting layer, when air leakage occurs between the door and window frame and the ground due to aging of the sealant after long-term use, the air pump can be used to supply air into the adjusting layer to fully fill the gap between the mounting frame and the door and window frame, thereby ensuring the airtight effect, wherein the sealing layer is an EPDM airtight material.

[0013] Furthermore, a pressure sensor is provided at the lower part of the interior of the door and window frame, and the output end of the pressure sensor extends to above the insulation board. The upper end of the adjustment layer is connected to the output end of the air pump through a connecting pipe. The air pump is located inside the door and window frame. A controller is provided on the door and window frame. The controller has a built-in single-chip microcomputer. The pressure sensor is electrically connected to the air pump through the single-chip microcomputer. When the pressure sensor detects that the pressure value of the airtight layer on the door and window frame decreases, the detected value can be transmitted to the single-chip microcomputer, and the single-chip microcomputer converts it into an electrical signal and transmits it to the air pump. The air pump is started to inflate the adjustment layer until a predetermined pressure value is reached. The pressure sensor model can be BMP280, the single-chip microcomputer model can be ESP32, and the air pump is a micro pump body, and its model can be XN-03.

[0014] Furthermore, one end of the connecting tube is connected to the air pump through a fixed tube, and a one-way mechanism is provided in the fixed tube, and the one-way mechanism includes a spring, a support plate, a piston and a fixed shaft. The fixed tube is a structure that is wide at one end and narrow at the other end, and the one-way mechanism is arranged in the narrow tube. One side of the support plate is assembled and connected to the fixed shaft through a spring, and one end of the fixed shaft is assembled and connected to the piston, and the piston is arranged toward the end of the wide tube. The support plate is an annular structure and is assembled and connected to the inner wall of the fixed tube, and a T-slot is provided in the fixed shaft. When the air pump inflates the fixed tube, the gas passes through the center position of the support plate and the surrounding of the spring from the T-slot into the position between the fixed shaft and the piston, and more gas is squeezed in the fixed tube, pushing the fixed shaft and the piston to move toward the wider end, and the spring is stretched until the piston completely detaches from the narrow tube. At this time, the gas can be discharged from the T-slot and enter the wide tube from the edge of the piston, thereby entering the regulating layer through the connecting tube. When there is no gas filling, the spring pulls back to drive the piston to shrink into the narrow tube to achieve a gas blocking effect and avoid air leakage.

[0015] Furthermore, a mounting plate is provided on one end of the adjusting layer connected to the mounting frame and the L-shaped steel plate, and a through groove which is not connected to the interior of the adjusting layer is provided at the center of the mounting plate. The through groove is used for passing a fixing nail, and the fixing nail is prevented from piercing the adjusting layer and causing air leakage.

[0016] Furthermore, a leveling layer is laid on the top of the outer beam, and a gasket is provided on one side of the L-shaped steel plate connected to the leveling layer and the mounting frame. The gasket is a polyurethane gasket, and the fixing nails are low thermal conductivity fixing nails. The gasket and the low thermal conductivity fixing nails can effectively avoid the formation of a thermal bridge effect on the L-shaped steel plate and the fixing nails.

[0017] In another aspect, the present invention provides a method for installing a low-energy-consumption door and window installation structure capable of improving air tightness, comprising:

[0018] Step S1: before installation, lay a second waterproof and air-tightening membrane on the outer wall of the outer beam in advance, and reserve a section on the upper end of the second waterproof and air-tightening membrane, assemble the installation frame at the reserved door and window installation positions on the ground and the wall, and lay the reserved section of the second waterproof and air-tightening membrane evenly on the upper end of the outer beam and the side wall of the installation frame, and lay the second waterproof and air-tightening membrane on both sides and the top of the installation frame and the wall;

[0020] Step S3, laying one end of the first waterproof and air-isolating membrane below on the upper side of the heat insulation board close to the indoor side, the other end of the first waterproof and air-isolating membrane is attached to the indoor side of the installation frame and extends to the indoor floor, and the first waterproof and air-isolating membrane is laid on both sides and the upper side of the installation frame and the wall;

[0024] The beneficial effects of the present invention are:

[0025] 1. The present invention adopts high-strength polyurethane heat-insulating and moisture-proof pads and anti-corrosion wood to solve the problem of hot and cold bridges in door and window frames, and adopts EPDM airtight materials, air-isolating membranes and other materials to ensure the airtightness of door and window frames, which can greatly improve the airtightness and thermal insulation of doors and windows, and avoid the formation of cold bridges at the junction of doors and windows and walls.

[0026] 2. The present invention can effectively avoid the formation of a thermal bridge effect on the L-shaped steel plate and the fixing nails by providing a gasket and fixing nails with a low thermal conductivity coefficient.
