Description
Technical Field
The utility model relates to a layering section bar.
Background
The gap that exists between the section bar inside casing that cavity glass and be used for installing cavity glass among the PVC door and window is the main reason that causes PVC door and window ventilative, though the glass sealing strip can play sealed effect, but current glass sealing strip is installed in the clearance between layering and glass more, and most exposes in the section bar outside, is very easily ageing along with the extension of live time, and the elasticity reduces after the glass sealing strip ageing, and sealed effect worsens. Therefore, the sealing effect between the hollow glass and the section bar in the existing PVC door and window is poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is to solve the poor problem of sealed effect between cavity glass and the section bar among the current PVC door and window, provides a layering section bar with reentrant corner sealing strip.
The utility model is composed of a pressing strip and a concave sealing strip;
a first sealing strip mounting groove is formed in the upper portion of the inner side of the pressing bar, a convex strip is arranged in the middle of the inner side of the pressing bar, and a second sealing strip mounting groove is formed in the lower surface of the convex strip; the lower part of layering is provided with the card strip, and reentrant corner sealing strip one end is installed in second sealing strip mounting groove, and the length of reentrant corner sealing strip is greater than second sealing strip mounting groove and the distance between the card strip bottom.
The utility model discloses principle and beneficial effect do:
the utility model discloses in the layering section bar with reentrant corner sealing strip, the layering realizes fixed mounting in the layering mounting groove of PVC door and window section bar through card strip joint. The inside corner sealing strip that the sand grip lower part set up is set up between layering and cavity glass, and general layering mounting groove sets up in the inside of section bar inner frame, therefore, after the card strip joint is in the layering mounting groove of PVC door and window section bar, the inside corner sealing strip with the lower terminal surface parallel and level of card strip takes place to buckle by the space restriction, and closely laminates with cavity glass and the section bar inside casing of installation on the section bar inside casing, realizes sealing the inside corner that forms between cavity glass and the section bar inside casing that is used for installing cavity glass. Because the reentrant corner sealing strip sets up inside door and window section bar, and not direct contact external environment, so have longer life. The reentrant corner sealing strip is crooked by space restriction emergence, compares with the form of relying on self elastic seal, and is inseparabler with the laminating of adjacent component, so has better sealed effect.
Drawings
FIG. 1 is a view of a door or window equipped with a batten profile having a female-corner weather strip in example 1;
FIG. 2 is a schematic structural view of a bead 1 in the bead section with a female-corner sealing strip in example 1;
fig. 3 is a schematic structural view of the inside corner sealing strip 2 in the molding strip with the inside corner sealing strip in example 1.
The specific implementation mode is as follows:
the technical scheme of the utility model is not limited to the specific implementation modes listed below, and also comprises any reasonable combination between the specific implementation modes.
The first embodiment is as follows: the pressing strip section with the internal corner sealing strips in the embodiment is composed of a pressing strip 1 and internal corner sealing strips 2;
a first sealing strip mounting groove 11 is formed in the upper portion of the inner side of the pressing strip 1, a convex strip 12 is arranged in the middle of the inner side of the pressing strip 1, and a second sealing strip mounting groove 13 is formed in the lower surface of the convex strip 12; the lower part of layering 1 is provided with card strip 14, and 2 one ends of reentrant corner sealing strip are installed in second sealing strip mounting groove 13, and the length of reentrant corner sealing strip 2 is greater than second sealing strip mounting groove 13 and the distance between the 14 bottoms of card strip.
In the pressing strip section with the internal corner sealing strips in the embodiment, the pressing strip 1 is clamped in the pressing strip mounting groove of the PVC door and window section through the clamping strip 14 to realize fixed mounting. The internal corner sealing strip 2 arranged at the lower part of the convex strip 12 is arranged between the pressing strip 1 and the hollow glass, and a common pressing strip mounting groove is arranged in the section bar inner frame, so that after the clamping strip 14 is clamped in the pressing strip mounting groove of the PVC door and window section bar, the internal corner sealing strip 2 which is parallel and level to the lower end face of the clamping strip 14 is bent under the limitation of space and is tightly attached to the hollow glass and the section bar inner frame which are arranged on the section bar inner frame, and the internal corner formed between the hollow glass and the section bar inner frame for mounting the hollow glass is sealed. Because the internal corner sealing strip 2 is arranged inside the door and window profile and does not directly contact the external environment, the service life is longer. The inside corner sealing strip 2 is bent due to the limitation of space, and is more tightly attached to an adjacent member than a form of elastic sealing by itself, so that a better sealing effect is achieved.
The second embodiment is as follows: the first difference between the present embodiment and the specific embodiment is: the section of the internal corner sealing strip 2 is rectangular. Other steps and parameters are the same as in the first embodiment.
The third concrete implementation mode: the first difference between the present embodiment and the specific embodiment is: one end part of the internal corner sealing strip 2 is provided with a tenon 21, and the tenon 21 is installed in the second sealing strip installation groove 13. Other steps and parameters are the same as in the first embodiment.
The fourth concrete implementation mode: the first difference between the present embodiment and the specific embodiment is: the main body of the pressing strip 1 is a strip-shaped section bar provided with a cavity. Other steps and parameters are the same as in the first embodiment.
The fifth concrete implementation mode: the first difference between the present embodiment and the specific embodiment is: the clamping strip 14 is clamped in a pressing strip mounting groove of the PVC door and window profile. Other steps and parameters are the same as in the first embodiment.
Example 1:
the embodiment is described with reference to fig. 1 to 3, and the batten profile with the internal corner sealing strip of the embodiment is composed of a batten 1 and an internal corner sealing strip 2;
a first sealing strip mounting groove 11 is formed in the upper portion of the inner side of the pressing strip 1, a convex strip 12 is arranged in the middle of the inner side of the pressing strip 1, and a second sealing strip mounting groove 13 is formed in the lower surface of the convex strip 12; the lower part of layering 1 is provided with card strip 14, and 2 one ends of reentrant corner sealing strip are installed in second sealing strip mounting groove 13, and the length of reentrant corner sealing strip 2 is greater than second sealing strip mounting groove 13 and the distance between the 14 bottoms of card strip.
The section of the internal corner sealing strip 2 is rectangular; a tenon 21 is arranged at one end part of the internal corner sealing strip 2, and the tenon 21 is arranged in the second sealing strip mounting groove 13; the main body of the pressing strip 1 is a strip-shaped section bar provided with a cavity; the clamping strip 14 is clamped in a pressing strip mounting groove of the PVC door and window profile.
The batten profile with the internal corner sealing strip of the embodiment can seal the internal corner formed between the hollow glass and the inner frame of the profile for mounting the hollow glass, and has longer service life.
