Description

  The present invention relates to a watertight packing used when constructing an exterior panel or the like.

  Conventionally, as shown in FIGS. 2 (a) and 2 (b), a heat insulating panel A in which a heat insulating material is filled between two metal shells has been provided. As such a heat insulating panel A, for example, it is fitted to one of the upper end portion and the lower end portion of the panel body 4 of the heat insulating panel A in which the heat insulating material 3 is filled between the facing front skin 1 and the back skin 2. A recess 7 is formed on the other side, a fitting protrusion 8 is formed on the other side, side walls 11 and vertical joint pieces 12 are formed on both ends of the heat insulation panel A, and the front side skin 1 is placed on the back side on the upper end of the panel body 4. And is formed by providing a horizontal joint side wall 5 that is substantially orthogonal to the panel surface (see, for example, Patent Document 1). Reference numeral 16 denotes a fixing groove for driving a fixing tool such as a nail, a tex or a screw. Reference numeral 41 denotes a packing accommodated in the fitting recess 7.

  Said heat insulation panel A is arranged in parallel up and down, right and left, and the outer wall etc. of a house are formed. In this case, as shown in FIG. 15, the heat insulating panels A that are vertically adjacent to each other are connected by fitting the fitting concave portion 7 and the fitting convex portion 8. A horizontal joint 13 is formed. The heat insulation panels A adjacent to the left and right are juxtaposed with the surface of the panel body 4 being substantially flush with each other, and vertical joints are formed on the surface side of the vertical joint pieces 12 adjacent to the left and right. The horizontal joints 13 and the vertical joints are filled with a sealing material for sealing. Reference numeral 66 denotes a fixing tool that is driven into the wall base from the fixing groove 16.

  On the other hand, the sealing material may harden and deteriorate due to aging, and there is a risk that rainwater may enter due to cracks caused by expansion and contraction of the heat insulation panel A due to thermal expansion. Further, in the uneven fitting portion, due to thermal expansion, the inside of the fitting portion tends to be a negative pressure compared to the outside, moisture is likely to enter the inside of the uneven fitting portion, and further, the insulation panel A There was a tendency for rainwater to infiltrate along the side edges. For this reason, the internal heat insulating material 3 may be deteriorated early. In particular, in the connection location where the corner portions of the four heat insulation panels A are located, the four heat insulation panels A are individually vibrated or repositioned, and the sealing material at the corner portions is easily cracked, There is a possibility that the watertightness at the corner portion is likely to be easily damaged. Then, as shown in FIG. 16, in the corner part where the four heat insulation panels A gather, the watertight packing P was arrange | positioned in the back surface, and the construction for maintaining the watertightness of a corner part was performed. In FIG. 16, one of the four heat insulation panels A (upper right heat insulation panel) is not shown. In the figure, reference numeral 14 is a vertical joint, reference numeral 60 is a wall base such as a pillar, reference numeral 61 is a discard plate, reference numeral 62 is a vertical joint member, reference numeral 64 is a refractory material, reference numeral 65 is a waterproof packing, and reference numeral 67 is a backup material. Reference numeral 68 denotes a sealing material.

  However, as shown in FIG. 17, the water-tight packing P has a complicated shape, so that it is necessary to mold urethane rubber, ethylene propylene diene rubber (EPDM) or the like using an injection molding injection method. In addition, the production capacity is limited by the number of molding dies, and delivery time may be required. Furthermore, since the watertight packing P is provided on the left and right sides of the heat insulation panel A, two types of watertight packing P having a line-symmetric shape are required as shown in FIGS. 17 (a) and 17 (b). Therefore, there is a risk that the cost is increased due to the labor and time required for manufacturing and the increase in the number of parts.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a water-tight packing that can be simplified in shape and can reduce costs by suppressing an increase in the number of parts.

  In the watertight packing P of the present invention, the panel main body 4 is formed by filling the heat insulating material 3 between the front side skin 1 and the back side skin 2, and between the pair of concave side walls 7 a provided at the upper end of the panel main body 4. A watertight packing P used in the heat insulation panel A in which the fitting concave portion 7 is formed and the fitting convex portion 8 is formed in the lower end portion of the panel main body 4, so as to follow the surface of the upper end portion of the panel main body 4. A surface covering portion P1 to be formed and a back surface covering portion P3 extending above the surface covering portion P1 and formed so as to be foldable along the back surface of the recess side wall 7a are substantially constant over the entire length in the longitudinal direction. It is formed in the shape of a cross section.

In the present invention, the side surface covering portion P2 which is formed to be bent along the side end face of the insulating panel A is no extends to the side of the surface cover portion P1.

  In the present invention, the side end face of the heat insulating panel A is formed on the surface of the side wall 11 by providing the side wall 11 facing the side end face of the panel body 4 with the gap s therebetween. It is preferable to include a side wall back surface covering portion P4 that extends upward and is foldable along the back surface of the upper end portion of the side wall 11.

  Since the watertight packing P of the present invention has a substantially constant cross-sectional shape over the entire length in the longitudinal direction, it is easy to manufacture, and matches the shape of the heat insulating panel A by folding the back surface covering portion P3 from the front surface covering portion P1. Therefore, it is not necessary to prepare water-tight packings P having different shapes on the left and right sides of the heat insulation panel A, and the cost can be reduced by making the shape simple and suppressing an increase in the number of parts.

Furthermore, the surface of the side wall back surface covering portion P4 of the watertight packing P provided on the lower heat insulating panel A is in close contact with or close to the side end surface of the fitting convex portion 8 of the upper heat insulating panel A. And as shown in FIG. 12, in the watertight packing P of FIG. 1, especially the ridge waterproof part 51 of the surface covering part P1 can prevent distribution | circulation of rain water etc. in the fixed groove | channel 16, and can improve waterproofness. Moreover, in the watertight packing P of FIG. 6 as shown in FIG. 13, in addition to the effect which the thing of FIG. 1 has, the circulation of the rainwater etc. in the horizontal joint 13 is prevented in the side running prevention part 50 of the surface covering part P1, Waterproofness can be improved.

  As shown in FIG. 14, the horizontal joint 13 can be filled with a sealing material 69. This sealing material 69 is the same as the sealing material 68 filled in the vertical joint 14, and the sealing material 69 can be filled in the range of 10 to 30 mm from the end portion of the horizontal joint 13 communicating with the vertical joint 14. Therefore, in the place where the four heat insulation panels A are adjacent, the vertical joint 14 and the horizontal joint 13 become cross joints, and the sealing material 68 and the sealing material 69 are arranged in a cross shape. And the waterproofness of the connection part of the heat insulation panel A which adjoins with the sealing material 68 and the sealing material 69 can further be improved.

  In the connection structure of the heat insulation panel A using the watertight packing P according to the present invention, when the sealing material 68 is partially broken (for example, the sealing material 68 is cut about 110 mm in the vertical direction at the cross joint portion). Even in the case of the case, the water leakage was suppressed and the waterproof performance was high in all test steps (average pressure 540 to 2200 Pa) of the dynamic wind pressure water tightness test (JIS A1414).
