DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint which is formed along a joint formed between joints of panel-shaped outer wall members which are preliminarily manufactured to a predetermined size for a building such as a prefab house. In particular, the present invention relates to a drainage guide material for a seal material which is improved so as to surely and relatively easily drain an outer wall joint portion formed by vertical joints and horizontal joints.

A conventional method of sealing the outer wall joint cross portion formed by the vertical joint portion and the horizontal joint portion is, for example, a method in which a plug member made of a foamed polyethylene material is fitted into a deep portion of the outer wall joint cross portion. , Sealing with a sealing material or caulking material (not shown), FIGS. 6 and 7
In general, dry sealing as shown in (1) has been widely used.

As shown in FIG. 6 and FIG.
The conventional sealing material 10 used for sealing has a waterproof

Consisted of

[0004] Incidentally, the outer wall joint second vertical joints located from the cross section CJ downward gasket VG ₂ is the sealing plate longitudinal joint gasket VG ₁ lower surface from the first of the SP material
In the same manner as described above. A vertical joint gasket VG ₁ for the longitudinal is fitted to joint VJ first in the outer wall joint cross section CJ, a plan view of the horizontal joint gasket LG extending across the inner portion of the longitudinal joint VJ As is apparent from FIG. 7, the first vertical joint gasket VG _{1, which} is usually formed from a synthetic rubber material such as chloroprene rubber, ethylene propylene rubber, or silicone rubber, or an olefin-based thermoplastic elastomer material, The first watertight seal member 11 was fitted on the outer opening side of the joint VJ, and the second watertight seal member 14 was pressed against the rear portion of the first watertight seal member 11.

[0005] The first water-stop sealing material 11 is formed in a plurality of pairs toward the opposite end faces of the outer wall members OW ₁₀ and OW ₁₁ which define the vertical joint VJ from the front end portion to the rear end portion of the central support portion 12. Of the second seal lip portion 13
Of the outer wall members OW ₁₀ , OW ₁₁
And a base 15 facing the side surface of the _one vertical frame member VF1 which defines the depth of the vertical joint VJ following the opposite end surface of the vertical joint VJ, and from the base 15 to the other vertical frame member V
It consisted by projecting the hollow seal portion 16 toward the side of F _2. Said first vertical joint gasket VG _1, the while blocking the vertical joints VJ, the sealing plate of the first water stop with respect to the upper surface of the SP which extends to also cover the lower end surface of the horizontal joint LJ The lower end face of the sealing material 11 is brought close to the predetermined distance, and the one vertical frame member VF ₁
By pressing the rear end of the first water-stop sealing material 11 against the tip of the second water-stop sealing material 14 to which the base portion 15 has been previously adhered and / or screwed to the side surface, A double water sealing means and an off-wall drainage means were formed.

On the other hand, the first vertical joint gasket VG ₁
The horizontal joint gasket LG which was also fitted along the horizontal joint portions LJ so as to bridge the upper surface of the sealing plate SP with the inner part than the first vertical joint gasket VG ₁ similarly to normal, chloroprene Rubber, ethylene propylene rubber,
A first water-stop seal member 17 formed of a synthetic rubber material such as silicone rubber or an olefin-based thermoplastic elastomer material, and a second stop provided adjacent to a rear portion of the first water-stop seal member 17. It consisted of a water sealing material 20.

And end faces formed by the lower end faces of the horizontal frame members LF ₁ and LF ₂ that define a part of the horizontal joint LJ).
The hollow seal portions 19 and 22 project from each other, and the base portions 18 and 21 are bonded and / or screwed in advance on the upper surface of the seal plate SP along the horizontal joint portions LJ. The double water sealing means was formed by pressing the upper peripheral surfaces of the hollow seal portions 19 and 22 of the first and second water-stop sealing materials 11 and 14 against the upper end surface of the horizontal joint LJ. . The innermost part of the seal plate SP was bent upward opposite to the outer end of the wall to prevent water leakage into the room.

[0008]

However, the conventional wet sealing method requires a lot of manpower and expertise in the on-site sealing of the outer wall members, and the sealing material causes water leakage due to deterioration with time. Meanwhile, the horizontal joint gasket LG constituting a conventional dry seal 10 is so traversing the longitudinal joint VJ in the back part than the longitudinal joint gasket VG ₁ wherein said first As apparent from FIG. 7, the vertical Joint VJ and vertical joint V
By setting the overall thickness or depth of J to be large, at least the vertical joint VJ at the outer wall joint cross portion CJ is set.
It was necessary to stop the water in the vicinity and drain the water outside the wall.

Therefore, the conventional dry outer wall joint cloth portion sealing method increases the material cost of the vertical and horizontal frame members VF ₁ , VF ₂ , LF ₁ , LF ₂ attached to the back side of each outer wall member, and increases the room cost. There was a disadvantage that the space was reduced.

[0010] The present invention solves the above-mentioned problems of the prior art, and makes it possible to reliably and easily water-stop and drain the outside wall of the outer wall joint cloth with a relatively compact structure. It is an object of the present invention to provide a part of drainage guide material.
