JP 2000-120215 A

In order to prevent the leakage of the enclosure, it is desirable to adopt a double or triple waterproof structure. However, if such a double or triple waterproof structure is used, the construction and structure become complicated and the cost is high. There was a problem of becoming.
The present invention aims to solve the above problems.
Conventionally, base materials such as field boards and concrete usually have a waterproof layer formed on the upper surface. However, if the base material contains moisture, moisture confined under the waterproof layer will be lost. It evaporates and this pressure causes the waterproof layer to swell. Therefore, if the outer plate is simply pasted on the base material, the waterproof layer is peeled off or cracked from the swollen portion, causing water leakage. For this reason, the waterproof work can be performed only when the base material is dry in fine weather. In addition, before the waterproofing work, a pretreatment for removing dirt and dust on the surface of the base material is required.
Another object of the present invention is to provide a waterproof outer shape that eliminates the problem of swelling of the waterproof layer and that has increased strength against wind pressure.

In order to achieve the above object, the present invention is a waterproof enclosure used for a roof or an outer wall, wherein a plurality of locations are provided by a base material and a plurality of adjacently arranged fasteners such as screws on the base material. A base metal plate fixed to the base metal plate, a plurality of adjacent base plates disposed on the base metal plate, and each lower surface is bonded to the upper surface of the base metal plate with an adhesive, and adjacent joint portions are partially bonded with an adhesive Overlap at least the lower part of the overlapped part is covered with a finish waterproof metal plate fixed to the base material via the base metal plate with a fastener such as a screw, and the joint of the finish waterproof metal plate And a band plate material fixed on the seam by an adhesive.
Further, the present invention is characterized in that the adhesive is a silicone-based waterproof adhesive.
In the present invention, both the upper part and the lower part of the overlapping part of the finished waterproof metal plate are fixed to the base material via the base metal plate by a fastener, and the band plate material is fastened to the overlapping part. The seam is fixed to the seam from above, and the seam and the head of the fastener are closed by the band plate material.
Further, the present invention is characterized in that a waterproofing agent is applied to the head of the fastener for fixing the base metal plate to the base material and the periphery thereof.
Further, the present invention is characterized in that the strip material is composed of a synthetic resin film.

  The present invention can provide an envelope having a simple structure and excellent waterproofness.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 shows an exploded external view of an enclosure 2 made of a roof. A base material 4 made of a material such as plywood or hard wood wool cement board or concrete is supported on a beam (not shown), and a base metal plate 6 made of a steel plate or the like is disposed on the base material 4. ing.

A plurality of portions of the base metal plate 6 are fixed to the base material 4 by fasteners 8 such as screws and anchor bolts. A silicon-based waterproof sealant 10 is applied around the fastening portion of the base metal plate 6 by the fastener 8 so as to cover the head of the fastener 8 and the fastening portion is waterproofed. . A silicon waterproof adhesive 12 is applied to the entire surface of the base metal plate 6, and a plurality of finished waterproof metal plates 14 made of steel plates are adhered to the surface of the waterproof adhesive applied so as to partially overlap each other. ing.

The overlapping portion G of the two adjacent waterproof metal plates 14 and 14 is bonded to each other by the silicone waterproof adhesive 15, and the overlapping portion G is fixed to the base material 4 by fasteners 16 such as screws at a plurality of locations. Has been. It straddles the seam T along the side edge 14a of the other finish waterproof metal plate 14 on the upper side disposed on the surface of one finish waterproof metal plate 14 of the two adjacent finish waterproof metal plates 14, A thin strip material 18 made of a synthetic resin film or the like is disposed in a region extending over the entire length of the joint T including the head of the fastener 16.

The strip 18 is fixed on the region including the seam T and the region including the head of the fastener 16 by an adhesive 20 such as a silicone waterproof adhesive. The base metal plate 6 on the base material 4 is also composed of a plurality of metal plates and is arranged adjacent to each other in a partially overlapping state. The adjacent arrangement configuration of the base metal plate 6 is the same as the adjacent arrangement configuration of the finish waterproof metal plate 14, the overlapping portion is bonded with an adhesive, and the overlapping portion is fixed to the base material 4 with screws.

When the overlapping portion of the base metal plates 6 and the overlapping portion of the finish waterproof metal plates 14 are positioned on the same line in the upper and lower sides, the overlapping portion of the two overlapping portions swells greatly. The overlapping portion of the metal plate 6 and the overlapping portion G of the finish waterproof metal plate 14 are shifted from each other so as not to overlap each other.

  In the envelope, the base metal plate 6 made of a steel plate is fixed to the base material 4 with a fastener 8, and the base metal plate 6 and the base material 4 constitute a strong base. Therefore, not only the problem of the swelling of the waterproof layer in the conventional waterproof construction can be solved, but also the strength against wind pressure can be increased.

  In this embodiment, the structure in which the base metal plate 6 is fixed to the base material 4 with the fastener 8 and the waterproofing agent 10 is applied to the head of the fastener 8 constitutes a primary water stop, and the base metal plate 6 The structure in which the adhesive 12 is applied to the surface of the substrate, the finish waterproof metal plate 14 is bonded thereto, and the overlapping portion is fixed to the base material 4 with the fastener 16 constitutes secondary water stop. Moreover, the structure which adhere | attached the strip | belt board material 18 to the joint T comprises the tertiary water stop, and the outer enclosure in this embodiment implement | achieves the triple waterproof structure by these structures.

  FIG. 3 shows another embodiment of the present invention. The overlapping portion G of the finish waterproof metal plates 14 and 14 is fixed to the base material 4 at the lower portion by the fastener 16 and the upper portion is waterproofed by silicon. It is bonded to the lower finish waterproof metal plate 14 via an adhesive 20.

That is, the upper finish waterproof metal plate 14 is not fixed to the base material 4 by the fastener. In the overlapping portion G of the finish waterproof metal plates 14, 14, the strip plate material 18 is disposed over the entire length across the joint T. 14 and 14 are bonded to the overlapping portion G and the vicinity thereof. Other configurations are the same as those of the embodiment shown in FIGS.

It is an explanatory exploded perspective view of the enclosure concerning the present invention. It is sectional drawing of a waterproof envelope. It is sectional drawing of the enclosure which shows other embodiment of this invention.
