Description

[Detailed description of the invention] [Field of industrial application] This invention is an improvement of an exterior wall waterproofing body used for waterproofing the upper end of the finishing mortar layer at the upper edge of the exterior wall of a building and the joints of the building wall. This is related to.

[Conventional technology]

As shown in Fig. 7, a conventional external wall waterproofing body of this kind has a holder c fixed to the upper end surface of a finishing mortar layer a with a fixing device b such as an anchor bolt, and a drainer cover d
After connecting the connecting side ends of the drainer covers d and d to each other, the joints between the drainer covers d and the rising wall a and the building wall e are filled with sealants f. It had a structure consisting of:

[Problem that the invention attempts to solve]

However, with this structure, there is a gap between the draining covers d and d, so unless the spacing between the draining covers d and d is made close to each other through the sealing material, rainwater will enter from between the two. Therefore, not only skill is required for positioning the draining cover d, but also a great deal of labor and time is required for other operations such as filling the sealing material. Further, there was a problem in that the waterproofness of the connecting portion was reduced due to the expansion and contraction of the draining cover.

[Means for solving problems]

This idea was made with the intention of solving the above problem, and it includes a long draining cover for waterproofing the joint between the building wall and the finishing mortar layer on the roof of a building, and a long draining cover that connects the draining covers to each other. An external wall waterproof body comprising a connecting holder, the holder being inserted into a groove horizontally provided in the joint part at the inner end of the horizontal plate part fixed to the upper end of the rising wall. A vertical wall is formed with a locking protrusion, and a hanging piece is provided at the outer end to hang down from the outer surface of the finished mortar layer, and a notch of an appropriate width is provided at the center of the horizontal plate. along the groove, an elastic protrusion whose tip is in close contact with the lower surface of the horizontal piece of the cover, and a plurality of weir lines substantially perpendicular to the elastic protrusion within the notch. The drain cover has a horizontal piece and a vertical piece to surround the outer surface of the holder, and an end of the horizontal piece engages with the locking protrusion. The present invention proposes an outer wall waterproof body in which an upper locking groove is formed, and a lower locking line is formed at the lower end of the vertical piece to engage with the lower end of the hanging piece.

〔composition〕

This invention will be explained below based on FIGS. 1 to 6.

Figures 1 and 2 show a perspective view and a cross-sectional view showing how the external wall waterproofing body of this invention is installed, and show the projecting edge of the upper end of the building wall A on the roof of the building, etc.
This is a case where it is used for waterproofing the joint between A' and the finishing mortar layer B. In this case, the outer wall waterproofing body is composed of elongated draining covers 1, 1... and these draining holders 2, and the holder 2 is, as shown in FIGS. 2 and 3, The finishing mortar layer B is installed horizontally on the upper end of the building wall A at the inner end of a horizontal plate portion 4 which is fixed to the upper end surface of the layer B by a fixing device 3 such as an anchor bolt. A standing wall 5 to be inserted into the groove 16 and a locking protrusion 6 protruding in an approximately L shape are formed on the building wall side of the upper end of the standing wall 5, and the horizontal portion 6' of the locking protrusion 6 is directed outward. A water return piece 8 is formed that hangs downward from the tip of the horizontal piece 7 extending toward the horizontal plate part 4, and at the other end, that is, the outer end of the horizontal plate part 4, a water return piece 8 is formed that hangs down from the outer surface of the finishing mortar layer B. It is formed by forming a hanging piece 9,
Moreover, the upper surface of the horizontal plate part 4 has an elastic protrusion 11 having a cutout part 10 in the center thereof and extending in the direction along the groove 16, that is, in the longitudinal direction of the draining cover 1.
11, protrudingly provided in a slightly inclined manner. In this case, a case is shown in which two elastic protrusions 11 are formed, but it is not necessarily necessary to provide two, and the same effect can be obtained by forming at least one. Also, the horizontal plate part 4
Anchor bolt mounting holes 12, 1 drilled in
Reference numeral 2 is a long hole extending in the width direction of the finishing mortar layer B, allowing for some adjustment of the installation.

Notch 10 of holder 2 configured as described above
is fitted with a draining plate 14 having a plurality of parallel weir lines 13, 13, . The end portion is fixed to the horizontal plate portion 4 of the holder 2 by a fastener 15 such as a blind rivet, and the outer hanging portion 1
4' is locked onto a step 9' formed on the hanging piece 9 of the holder 2, and the outer surfaces of the hanging piece 9 and the hanging part 14' are flush with each other, but this is not necessarily the case. The fastener 15 may be used for the
There is no need to provide

On the other hand, as shown in FIG. 4, the draining cover 1 has a horizontal piece 1a and a vertical piece 1b to surround the outer surface of the horizontal plate part 4 and the hanging piece 9 of the holder 2, and has a horizontal piece 1a and a vertical piece 1b. At the end of the holder 2
An upper locking recessed line 1c that engages with the locking protrusion 6 of the holder 2 is formed, and a lower locking line 1d that engages with the lower end of the hanging piece 9 of the holder 2 is formed at the lower end of the vertical piece 1b. It consists of

In order to install the exterior wall waterproofing body of this invention, which consists of the draining cover 1, holder 2, and draining plate 14 configured as described above, as shown in FIG.
First, the holder 2 with the draining plate 14 fitted in the notch 10 in advance is fixed to an appropriate location of the finishing mortar layer B with a fixing device 3 such as an anchor bolt, and then the connecting side of the adjacent draining cover 1 is fixed. After the upper locking groove 1c is engaged with the locking protrusion 6 of the holder 2, the lower locking groove 1d is inserted into the hanging piece 9 of the holder 2.
by engaging the lower ends of the horizontal pieces 1a of the adjacent draining covers 1, 1 in a snap-like manner,
After connecting the elastic ridges 11 of the holder 2 in close contact with each other and interposing the back-up material 17 at the joint between the upper surface of the upper locking groove 1c of the draining cover 1 and the building wall A, the seal is sealed. Filling with material 18 completes the installation work.

As shown in FIG. 6, if a retaining wall 1e is provided upright on the upper surface of the upper locking groove 1c of the draining cover 1, the back-up material 17 can be reliably supported by the retaining wall 1e. In addition, the sealing material 18
It is possible to improve the waterproofness of the sealing material 18, and even if the sealing material 18 is damaged, it is possible to prevent rainwater from entering.

[Effect of idea]

As explained above, according to the exterior wall waterproofing body of this invention, the draining cover can be connected by snap-like engagement with the holder fixed to the upper end surface of the finished mortar layer, and the draining cover The elastic protrusions provided on the holder can be attached to the lower surface in close contact with each other, and the holder is integrally fitted with a draining plate having a plurality of weir lines extending in a direction orthogonal to the elastic protrusions. Therefore, it can be easily installed without requiring any skill, and the waterproofness can be improved.In addition, the sealing material only needs to be filled in one place, which can reduce the number of construction steps and significantly reduce costs. In addition, rainwater that enters between the draining covers can be blocked by the weir strips of the draining plates and can be drained to the outside, which improves the structure of the building. The service life can be greatly increased, and excellent effects such as the draining cover not rattling or falling off due to wind pressure etc. can be obtained, and its utility value is remarkable.
