Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a sealing structure for a gap between an inner wall and an outer window. Background Art

[0002] The application of strip windows in the construction field is becoming more and more widespread, especially in public buildings such as hospitals, commercial offices, and hotels. Strip windows are mostly used for exterior windows of buildings and are installed on the facade. The upper and lower horizontal frames are fixed on the main structure. Usually, there is a gap between them and the inner wall after installation. Considering the fire protection requirements and the requirements of sound insulation of adjacent rooms, the gap between the inner wall and the outer window needs to be sealed. At this stage, the commonly used sealing methods are fireproof rock wool sealing or laying autoclaved fly ash sand bricks. Fireproof rock wool has a poor plasticity effect after sealing due to its soft material, and it cannot be processed after sealing on the side close to the glass. The rock wool will be photocopied from the outside of the outer window, which looks bad. There are two methods of sealing with autoclaved fly ash sand bricks: laying before the installation of the strip window or laying after installation, but both have defects. If masonry is carried out before the strip window is installed, the facade close to the glass side can be decorated after masonry to ensure the visual effect of the outside of the window. However, if the glass is thick, the installation of the glass cannot be guaranteed. If masonry is carried out after the strip window is installed, there is also a situation where the side close to the glass cannot be processed after being blocked, resulting in poor appearance.

[0003] The utility model aims to solve the deficiencies of the prior art and provides a sealing structure for the gap between an inner wall and an outer window.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a sealing structure for a gap between an inner wall and an outer window, the outer window being a strip-shaped window profile and a strip-shaped window glass installed in the strip-shaped window profile, and a sealing structure is provided for the gap between the strip-shaped window glass and the inner wall, including: a sealing box, the sealing box including: a flame retardant box, the flame retardant box being formed by nailing four flame retardant boards together, the flame retardant box having gypsum boards fixed on the other three sides except one side against the wall with self-tapping screws, the gypsum board having a finishing layer on the side close to the strip-shaped window glass, the sealing box being glued to the side of the inner wall close to the strip-shaped window glass with foam glue, back pressure gaps being provided on both sides of the foam glue, anti-cracking mortar leveling layers being provided on both sides of the sealing box, a wire mesh being hung at the junction of the sealing box and the inner wall, indoor finishing layers being provided on both sides of the sealing box and the inner wall, and the gap between the sealing box and the strip-shaped window glass being filled with glass glue.

[0005] Furthermore, the thickness of the blocking box is equal to the thickness of the inner wall, the height of the blocking box is equal to the height of the outer window, and the width of the blocking box is equal to the distance between the inner wall and the outer window scaled down by 5 mm.

[0006] Furthermore, the thickness of the flame retardant board is 15 mm, and the flame retardant board is painted with anti-corrosion and fire-retardant paint.

[0007] Furthermore, the gypsum board is a paper-faced gypsum board with a thickness of 9.5 mm.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1 and 2As shown, a sealing structure for the gap between an inner wall and an outer window is provided, wherein the outer window is a strip-shaped window profile 1 and a strip-shaped window glass 2 installed in the strip-shaped window profile 1, and a sealing structure is provided for the gap between the strip-shaped window glass 2 and the inner wall 3, including: a sealing box, wherein the sealing box includes: a flame retardant box 4, wherein the flame retardant box 4 is formed by nailing four flame retardant boards together, and the flame retardant box 4 is fixed with gypsum boards 5 on the other three sides except the side against the wall with self-tapping screws, and the gypsum board 5 is made into a finishing layer 6 on the side close to the strip-shaped window glass 2, and the sealing box is glued to the side of the inner wall 3 close to the strip-shaped window glass 2 with foam glue 7, and back pressure gaps are provided on both sides of the foam glue 7, and anti-cracking mortar leveling layers 8 are provided on both sides of the sealing box, a wire mesh 9 is hung at the junction of the sealing box and the inner wall 3, and an interior finishing layer 10 is provided on both sides of the sealing box and the inner wall 3, and the gap between the sealing box and the strip-shaped window glass 2 is filled with glass glue 11. The blocking box is made of rigid materials and is installed after being confirmed to be intact. The blocking box is pasted with foam glue 7 to ensure its firm installation. The wire mesh 9 is used to avoid cracking of the blocking part. The anti-cracking mortar leveling layer 8 is used to ensure that both sides of the blocking box are consistent with the indoor wall.

[0019] The thickness of the blocking box is equal to the thickness of the inner wall 3 , the height of the blocking box is equal to the height of the outer window, and the width of the blocking box is equal to the distance between the inner wall 3 and the outer window reduced by 5 mm.

[0020] The thickness of the flame retardant plate is 15 mm, and the flame retardant plate is painted with anti-corrosion and fire-retardant paint.

[0021] The gypsum board 5 is a paper-faced gypsum board with a thickness of 9.5 mm.

[0022] The finishing layer 6 is made by applying two coats of putty and two layers of tough paint. The purpose is to achieve a better effect of photocopying the exterior window facade after the plugging box is installed. Suitable finishing layer 6 can be selected according to demand, and is not limited to the tough paint described in the present invention.

[0023] The foam glue 7 has a back pressure of 20 mm on both sides.

[0024] The interior finishing layer 10 is made by applying two coats of putty and two layers of tough paint, or by using bamboo fiberboard.

[0025] The construction method of this utility model is as follows: After the strip window profile 1 is installed, the verticality of the strip window profile 1 is adjusted, the strip window glass 2 is installed, and after adjustment and fixing, a blocking box is fabricated. The size of the blocking box is determined based on the thickness of the interior wall 3, the height of the exterior window, and the distance from the interior wall 3 to the exterior window. The blocking box is fabricated using flame-retardant board and gypsum board 5, and then a finishing layer 6 is fabricated. Before installing the blocking box, ensure that the finishing layer 6 on the side closest to the strip window glass 2 is intact. Use foam glue 7 to adhere the blocking box to the gap between the interior wall 3 and the exterior window to ensure a secure and vertical installation. Ensure that a 5mm gap is left between the blocking box and the strip window glass 2 after installation. After the sealing box is installed, the foam glue 7 is back-pressed and leveled with an anti-cracking mortar leveling layer 8. When leveling, a wire mesh 9 is hung at the junction of the sealing box and the wall. After leveling, the interior finishing layer 6 is constructed. Finally, the 5mm gap reserved between the sealing box and the strip window glass 2 is glued with glass glue 11, and the glue must be straight and smooth.

[0026] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
