DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a vertical joint sealing material of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of the conventional vertical joint sealing material of the present invention cut along the line AA in FIG. 5, similarly to FIG. FIG. 2 is a cross-sectional view, FIG. 2 is a partially cutaway front view of the vertical joint sealing material according to the present invention, and FIG. 3 is a perspective view of the vertical joint horizontal end sealing material according to the present invention. FIG. 4 is a perspective view showing a state in which the vertical joint horizontal edge sealing material of the present invention is mounted on the vertical joint that intersects with a roof protruding from the outer surface of the house outer wall panel.

The essential parts of the vertical joint sealing material of the present invention shown in FIGS. 1 to 4 are, for example, natural rubber, ethylene-propylene solid rubber material, ethylene-propylene A sponge rubber material, a styrene-based, olefin-based, vinyl chloride-based, urethane-based thermoplastic elastomer material, or a rubber-like elastic material such as a thermoplastic elastomer foam material, and has a generally elongated cross-sectional shape of an anchor. Gasket vertical joint primary sealing material VS
₁ and a round bar-shaped vertical joint secondary sponge sealing material VS _2S made of sponge rubber or resin sponge material.

Further, the features of the vertical joint sealing material of the present invention include a flat plate portion PL having a substantially L-shaped side surface, a sponge portion SP layered on the side surface of the flat plate portion PL, and the flat plate portion. by simple insertion operations on the longitudinal joint VJ vertical joint horizontal end seal member VH _S consisting comprises a standing lowered positioning unit ST from the horizontal extension end vicinity of PL, the longitudinal joint secondary sponge seal The vertical joint VJ in the vicinity of the intersection while securely pressing the lower end surface and the rear side surface of the material VS _2S.
The purpose is to provide a good seal.

Furthermore, the longitudinal joint sealing material of the present invention, said plate PL and the positioning portion ST of the longitudinal joint horizontal end seal member VH _S is, since a hard resin or a metal flat plate, the longitudinal flexural rigidity is reinforced grout horizontal end seal member VH _S, the inserted for joint width is relatively narrow to improve the insertion positioning accuracy with respect to the longitudinal joint VJ not easy, water cut of the intersection It has a reinforcing effect. The vertical joint secondary sponge sealing material VS _2S is not limited to a round bar shape in cross section, but may be changed to a rectangular shape. the lower end surface and a rear side opposite to each crimping surfaces of the rising and horizontal area in the wood VH _S is, as long as it has a sustainable sufficient crimping state shape.

The above-mentioned longitudinal joint primary sealing material VS ₁ , longitudinal joint 2
Typical attachment methods: Sponge sealant material VS _2S and vertical joint horizontal end seal member VH _S is as follows.
First, a notch concave portion 7 which intersects with the vertical joint VJ at a predetermined width is previously formed in the outer surface of the residential outer wall panel OW, and the respective residential outer wall panels OW are assembled to form the vertical joint VJ. I do. Thereafter, the roof part 1 is attached to a predetermined position, and a lower holding edge 4 is disposed below the notch recess 7 so as to hold the rain hold 6 of the roof part 1. Another sealing material 3 is filled on the upper surface of the holding edge material 4.

Next, the longitudinal joint JV pressed the vertical joint horizontal end seal member VH _S to block across lacks the cut of the positioning portion ST which is lowered from the vicinity its horizontal extension end by combining with the outermost surface and visually recess 7, determine the press-fit position relative to the longitudinal joint JV of the longitudinal joint horizontal end seal member VH _S. Thereafter, the longitudinal joint horizontal end seal member VH said longitudinal joint secondary sponge seal material while bonding the lower end surface and the rear side of the longitudinal joint secondary Sponge sealant VS _2S to the rising and horizontal area in _S VS _2S Into the specified position, and finally the vertical joint 1
Press-fitting the next seal material VS _1. When the insertion of the entire vertical joint sealing material is completed, the upper holding edge 2
The outer surface of up coated with a thin iron plate 5, filling the sealing material 3 in the horizontal extended tip portion of the longitudinal joint horizontal end seal member VH _S.

The vertical joint horizontal end sealing material VH _S attached as described above has a cutting dimension in which the sponge portion SP has a cutting dimension generated by an on-site aligning operation of the lower end surface of the vertical joint secondary sponge sealing material VS _2S . Even if there is a variation, each crimping surface is elastically deformed to an extent necessary for sealing, thereby preventing infiltration of the dive RW from the intersection and its vicinity, thereby preventing infiltration into the housing room.

[0019]

The above-described vertical joint sealing material of the present invention has the following novel effects. That is, the vertical joint sealing material of the present invention is the vertical joint sealing material for sealing the vertical joint of the housing outer wall panel that intersects with the roof protruding from the outer surface of the housing outer wall panel. The vertical joint sealing material is composed of the vertical joint primary sealing material, the vertical joint secondary sponge sealing material, and the vertical joint horizontal end sealing material, and further, the vertical joint horizontal end sealing material has side surfaces. Comprises the flat plate portion formed in a substantially L-shape, the sponge portion layered on a side surface of the flat plate portion, and the positioning portion lowered from near a horizontal extension end of the flat plate portion. Therefore, good waterproofness can be ensured by a simple operation of inserting the vertical joint horizontal end sealing material into the vertical joint at the intersection and the vicinity thereof.

Further, in the vertical joint sealing material of the present invention, since the flat portion and the positioning portion of the vertical joint horizontal end sealing material are made of a hard resin or metal flat material, The bending rigidity of the sealing material is reinforced, the positioning accuracy of the insertion work with respect to the vertical joint is improved, and the lower end surface and the rear surface of the secondary sealing material of the vertical joint are reliably brought into contact with each other, so that the water stopping property of the intersection is provided. It has become possible to achieve a reinforcing effect.
