JPH11350840A - Water stopping method for multiple window sash vertical frame joint part - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent generation of leakage of rain water by providing a water stopping member constructed of a plate shaped core material and nonvulcanization butyl rubber covering the material at a joint upper part between adjacent unit sash vertical frames, and filling the outer circumference thereof with water resistant mortar. SOLUTION: A plurality of unit sashes 1 each of which comprises two vertical frames 2, one upper frame 3 and one lower frame are connected laterally, and the both frames 2, 2 are connected by a joint part 4 to each other. A joint water stopping member 5 is constructed of a core member 6 made of steel plate and nonvulcanization butyl rubber 7 coverting the whole of the member 6 and has a proper viscousity, rigidity and elasticity. The member 5 is pressed against the joint part 4 between the frames 2, 2 and adhered thereto. A gap between the upper frame 3 of the sash 1 and a wall 11. Since the rubber 7 has sticking property a water stopping mortar 9 is surely brought into contact therewith. Accordingly, prevention of leakage of water is assured, and displacement caused by an earthquake is absorbed and breakage of window pane as well as buckling of the sash 1 can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for stopping water at a joint of a vertical frame in a window sash.

[0002]

2. Description of the Related Art Conventionally, a vertical frame 2,
A metal backing plate or a resin lid was attached to the upper part of the joint 4 between the two.

[0003]

However, the metal backing plate and the lid made of resin have poor integration due to the difficulty in adhering the waterproof mortar, and as a result, the joint between the backing plate and the lid and the sash is poor. There was a fear that rainwater leaked due to a gap in the part.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The present invention improves the reliability of the water stopping performance at the upper part of the joint of a sash when attaching a window sash to a concrete wall. To provide a method for stopping water at a vertical frame joint of a continuous window sash.

[0005]

In order to achieve the above-mentioned object, a method for stopping water at a vertical window joint of a window sash according to the present invention is to provide a plate-like structure at the upper part of a joint between vertical frames of adjacent unit sashes. Is to install a waterproof material for joints in which the core material is coated with non-vulcanized butyl rubber, and to fill the waterproof mortar around the waterproof material and the unit sash.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. <B> Joint part 4 of continuous window sash 10 The continuous window sash 10 is a window frame in which two or more single sashes 1 are continuous horizontally. Each single sash 1 is a unitized sash 1 composed of two vertical frames 2, an upper frame 3, and a lower frame. The plurality of unit sashes 1 are connected to a concrete wall 1
Incorporate in 1. Then, the vertical frames 2 and 2 of the adjacent sashes 1 and 1 are connected to each other by a hardware (not shown) at the joint 4 (B in the figure). A joint water-stopping material 5 described later is installed on the upper part of the joint portion 4.

<B> Waterproofing Material 5 for Joint The waterproofing material 5 for joint is formed by forming a steel plate having a rectangular flat surface as a core material 6 and coating the whole with a non-vulcanized butyl rubber 7. Therefore, it has appropriate viscosity, rigidity and elasticity. The core member 6 may be a hard vinyl chloride resin plate or the like instead of the steel plate.

The size of the waterproofing material 5 for the joint is slightly larger than the expected size (D) of the unit sash 1 and the size (B) of the joint 4 respectively. The specific plane size b × d of the water stopping material 5 is a length of one side b = B + 20
mm, and the length d of the other side is about d = D + (2 to 5 mm).

The water-stopping material 5 for a joint has a simple structure, is easy to process and manufacture, and is suitable for mass production, and is excellent as a weather-resistant member.

[0010] By attaching a release paper 8 to at least the surface of the water-stopping material 5, the water-stopping material 5 can be cured to prevent adhesion and the like during handling such as transportation, storage, and construction.

<C> Water stopping method of the joint part 4 The joint water stopping material 5 is installed on the upper part of the joint part 4 between the vertical frames 2 and 2 of the adjacent unit sashes 1 and 1. At that time, the waterproof material 5 may be installed at the stage of the sash 1 being laid, or may be installed after the sash 1 is installed in the wall 11. In the latter case, the vertical frame 2,
Since there is a sufficient gap between the top end of the wall 2 and the lower surface of the wall 11, the waterproof material 5 is inserted horizontally into this gap, and installed and attached to the top ends of the vertical frames 2 and 2. . That is, since the water-stopping material 5 is made of the non-vulcanized butyl rubber 7 having adhesiveness and is larger than the dimension (B) of the joint part 4 and the expected dimension (D) of the sash 1, the non-vulcanized butyl rubber 7 is formed. Can be easily adhered by pressing the water-stopping material 5 so as to bite into the edge of the top end of the vertical frames 2 and 2. Thereby, compared to the conventional installation method using a metal backing plate or a resin lid,
Construction can be performed much more easily and reliably.

Next, the release paper 8 on the surface of the installed water-stop material 5
After removing the waterproof mortar 9 around the unit sash 1
Fill. That is, the gap between the upper frame 3 of the sash 1 and the wall body 11 is densely filled with the waterproof mortar 9. Thereby, since the non-vulcanized butyl rubber 7 of the water blocking material 5 has adhesiveness, the waterproof mortar 8 is securely adhered. In addition, 12 in the figure is a vertical frame 2,
Reference numeral 13 denotes a window glass.

[0013]

Since the present invention has been described above,
The following effects can be obtained. At the upper part of the joint between the vertical frames of the window unit sash, a water-stopping material for a joint made by coating a plate-shaped core material with non-vulcanized butyl rubber is installed,
By filling the waterproofing material and the waterproof mortar around the unit sash, <a> compared to the conventional waterproofing method using a metal backing plate or a resin lid, the construction is simpler and more reliable, Reliability is improved. <B> The water-stopping material has excellent adhesion to the vertical frame, and the unified vulcanized butyl rubber and the waterproof mortar are more integrated, so the continuity of the water-stopping is achieved. Thus, the prevention of water leakage at the upper part of the joint is ensured. <C> For non-vulcanized butyl rubber absorbs expansion and contraction due to expansion and contraction due to the temperature of the sash and displacement of the joint of the sash vertical frame due to external force such as an earthquake, forced force is generated in the sash. There is no. As a result, buckling of the sash, breakage of the window glass, and the like are eliminated.
