Description

Technical Field

[0001] The present invention relates to the technical field of building thermal insulation, and more particularly to a connection node between a PEC wall and an energy-saving window. Background Art

[0002] Cold bridges and thermal bridges mainly refer to the situation when the building's outer envelope structure conducts heat with the outside world. Since the heat transfer coefficient of certain parts of the envelope structure is significantly greater than that of other parts, heat is concentrated and transferred quickly from these parts, thereby increasing the building's air conditioning, heating load and energy consumption.

[0003] The cold bridge and thermal bridge effects caused by the thermal insulation structure of the house, the door and window frames, are much higher than those caused by other parts. Since the door and window frame structure is relatively complex and has high requirements for materials, it is difficult for general materials to take into account thermal insulation, durability and ease of use at the same time. In general house construction, especially prefabricated house construction, the cold bridge and thermal bridge effects in the door and window frames are serious, which leads to a decrease in the thermal insulation performance of the house, a large amount of energy is wasted, and it is not conducive to the promotion of prefabricated house construction. In addition, since the existing door and window frame materials are basically different from the wall materials, the expansion and contraction of different materials are different at different temperatures. The existing connection structure between the door and window frames and the wall will cause gaps to form between the door and window frames and the wall. Even if the structural glue is filled in time, it will loosen after long-term use, causing direct exchange of air between indoor and outdoor, resulting in a decrease in the thermal insulation performance of the house. Summary of the Invention

[0004] To address this problem in practical applications, the present invention aims to propose a connection node between a PEC wall and an energy-saving window. The specific solution is as follows:

[0005] A connection node between a PEC wall and an energy-saving window comprises a wall, a window and a connection assembly, wherein the wall is provided with an installation space for installing the window, the window comprises a window sash body and a window frame, the connection assembly is arranged between the window frame and the wall so that the window frame can be installed on the wall, the connection assembly comprises a first stop block, an insulation block and a water retaining angle aluminum, the first stop block is placed in the installation space and is fixedly connected to the wall close to the outside, the insulation block is fixedly arranged on the side of the first stop block facing away from the wall, the window frame comprises a first fixing portion and a second fixing portion, a fixed space for locking the insulation block is formed between the first fixing portion and the second fixing portion, a water retaining angle aluminum is provided on the side of the insulation block close to the room, the water retaining angle aluminum is fixed on the wall, and the water retaining angle aluminum itself is bent so that one side abuts the insulation block and the other side abuts the wall.

[0006] Through the above technical solution, the window frame is fixedly installed on the wall using the fixed space formed by the first fixing part and the second fixing part, and then the window sash body is installed on the window frame to complete the connection between the window and the wall. The heat preservation block is used to reduce the indoor heat dissipated from the window and the wall to the outside, thereby maintaining the indoor temperature. Then, the water retaining angle aluminum is set on the side of the heat preservation block close to the indoor side, and one side of the water retaining angle aluminum abuts on the heat preservation block and the other side abuts on the wall, thereby strengthening the sealing effect of the wall edge gap, preventing the indoor heat preservation efficiency from decreasing, and improving the overall heat preservation performance of the building. In addition, the structural design of the present invention is reasonable, which is convenient for orderly installation and avoids cross installation to prolong the construction period.

[0007] Furthermore, a side of the second fixing portion facing away from the window frame is bent in a direction close to the first fixing portion to form a limiting angle.

[0008] Through the above technical solution, the limiting angle is used to prevent the unstable connection between the window frame and the wall when the insulation block is fixed in a fixed space. The limiting angle forms a limiting effect in the direction along which the window frame moves away from the wall, thereby enhancing the stability of the connection between the window frame and the wall.

[0009] Furthermore, an expansion piece is provided between the insulation block and the water retaining angle aluminum, and the expansion piece abuts against the wall.

[0010] Through the above technical solution, when there is moisture between the window and the wall, the expansion piece absorbs water and expands to dry the moisture, thereby preventing the moisture from affecting the connection between the window and the wall, such as metal rusting and reduced insulation effect.

[0011] Furthermore, a sealing strip is provided on a side of the expansion member facing away from the wall, and the sealing strip is provided between the insulation block and the water retaining angle aluminum.

[0012] Through the above technical solution, the sealing strip is used to strengthen the tightness of the connection between the wall and the window, thereby improving the overall thermal insulation performance of the building.

[0013] Furthermore, a second stopper is provided on the side of the water retaining angle aluminum facing away from the heat preservation block, and the second stopper is fixed on the first stopper.

[0014] Through the above technical solution, the second block is used to enhance the stability of the water retaining angle aluminum, and the second block can be used to block the connection between the window and the wall, thereby improving the overall aesthetics of the interior of the building.

[0015] Furthermore, a decorative window molding is provided on the side of the wall close to the interior, and the decorative window molding abuts against the second stopper.

[0016] Through the above technical solution, the edges of the installation space are hemmed with decorative window moldings to improve the overall aesthetics of the building.

[0017] Furthermore, a flashing plate is provided on the wall, which is fixedly installed in the wall and arranged on both sides of the window in the height direction. The flashing plate extends out of the wall in the outdoor direction and bends downward in the height direction to form a drainage portion.

[0018] With this technical solution, the flashing plate drains outdoor rainwater away from the window, preventing it from flowing vertically from the wall onto the window and soaking the window or the connection between the window and the wall. Furthermore, draining rainwater away from the window prevents it from wetting the window and obstructing the view from inside.

[0019] Furthermore, the side of the flashing plate facing away from the wall abuts against the window frame.

[0020] Through the above technical solution, the tightness of the connection node between the wall and the window is improved, and rainwater is prevented from soaking the connection node between the window and the wall.

[0021] Furthermore, the sealing strip is provided at the junction of the flashing plate and the window frame.

[0022] Through the above technical solution, the sealing strip is used to strengthen the tightness of the connection between the wall and the window, thereby improving the overall thermal insulation performance of the building.

[0023] Furthermore, an insect-proof net is provided in the wall, and the insect-proof net is arranged close to the flashing board.

[0024] Through the above technical solution, since the mesh of the insect-proof net is small, most pests cannot drill through the insect-proof net to enter the room, thereby improving the hygiene of the building interior and preventing pests from penetrating into the wall and causing damage to the wall.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) The window frame is fixedly installed on the wall using the fixed space formed by the first fixing part and the second fixing part, and the window sash body is then installed on the window frame to complete the connection between the window and the wall. The heat preservation block is used to reduce the indoor heat dissipated from the window and the wall to the outside, thereby maintaining the indoor temperature. Then, a water-retaining angle aluminum is provided on the side of the heat preservation block close to the indoor temperature, with one side of the water-retaining angle aluminum abutting against the heat preservation block and the other side abutting against the wall, thereby strengthening the sealing effect at the edge gap of the wall, preventing the indoor heat preservation efficiency from decreasing, and improving the overall heat preservation performance of the building. In addition, the structural design of the present invention is reasonable, which is convenient for orderly installation and avoids cross-installation to prolong the construction period.

[0027] (2) The limiting angle is used to prevent the connection between the window frame and the wall from being unstable when the insulation block is fixed in a fixed space. The limiting angle forms a limiting effect in the direction of the window frame away from the wall, thereby enhancing the stability of the connection between the window frame and the wall;

[0028] (3) Use flashing to drain outdoor rainwater away from the window, preventing it from flowing vertically from the wall onto the window and soaking the window or the connection between the window and the wall. Furthermore, draining rainwater away from the window prevents it from wetting the window and preventing the view outside from being obscured. BRIEF DESCRIPTION OF THE DRAWINGS
