Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Technical Field of the Invention] The present invention is directed to the use of waterproof roofing from the upper end of a waterproof roofing raised as a parapet of a concrete flat roof, or from the upper end of a waterproof layer such as a tile attached to an external wall surface. Regarding temporary water stoppage to prevent rainwater from penetrating into the building structure.

[Technical background of the invention and its problems]

Until now, in order to prevent rainwater from penetrating into the structure from the upper end of the waterproof roofing set up on the parapet, it has been possible to form small grooves horizontally on the inner wall of the parapet. After inserting the upper end of the waterproof roofing,
The rising part was covered with waterproof mortar or asphalt, but in more delicate cases, bricks were added to the rising part of the waterproof layer and stacked with mortar to the bottom of the Kasagi to stop rainwater from flowing from the top of the rising part. was. On the other hand, for external walls of buildings that have been coated with a waterproof layer using magnetic tiles, waterproof mortar, or various resin-based spray paints, if gaps or cracks occur at the top of the waterproof layer, water will leak through the underside of the eaves of the building. Because rainwater sometimes seeps into the structure through gaps and cracks, a downward wall or groove was formed at the tip of the eaves to block the water from flowing down.

However, in reality, it is extremely troublesome to form horizontal small grooves on the parapet as described above, and the wooden frame for forming the small grooves gets buried in the parapet, making it impossible to remove the wooden frame and making it waterproof. Poor construction work was carried out in which the roofing was erected and hidden with waterproof retaining, or the top end of the waterproof layer was only covered with mortar or mortar and bricks without creating a small groove.As a result, the gap between the cap and the waterproof retaining was If gaps or cracks were formed in the roofing, rainwater could seep into the backside of the waterproof layer from the top of the waterproof roofing, impairing the durability of the roofing structure. In addition, in order to prevent rainwater from flowing down the eaves, it is difficult to assemble the formwork before pouring concrete, and the wooden frame that forms the groove is embedded in the formwork after the formwork is removed. Many of them were omitted because they were not removable, or they did not have sufficient water-stopping function. As a result, rainwater permeates through gaps and cracks at the top of the exterior walls, causing tiles and waterproof coatings to peel off, which is not only aesthetically pleasing, but also has the major drawback of accelerating the deterioration of the building blocks. In addition, repair work for buildings with defective construction is extremely difficult and must be carried out frequently until the causes of rainwater infiltration are completely removed, resulting in enormous costs and labor. Ta.

[Purpose of the invention]

The present invention was made based on the above-mentioned circumstances, and an object of the present invention is to provide a water stop plate that is easy to construct and can completely prevent rainwater from penetrating from the ends of the waterproof layer.

[Summary of the invention]

The outline of the waterstop plate according to the present invention for achieving the above object is that a plurality of lowering pieces are provided in parallel to the width direction of the horizontal substrate on the lower surface of a strip-shaped horizontal substrate to form a downward groove,
The present invention is characterized in that an appropriate number of anchors are protruded from the upper surface of the horizontal substrate at appropriate intervals.

[Embodiments of the invention]

An embodiment of the water stop plate according to the present invention will be described in detail with reference to the drawings. In the first embodiment shown in FIG. Five parallel downward grooves 3 are formed by the adjacent lower pieces 2, 2 and the horizontal substrate 1, which are provided in parallel over the entire length. Under the lowering piece 2 at one side end, an extension piece 2'' is provided which is inclined diagonally downward on the side of the groove 3 and bent directly downward in the middle. A large number of figure-7 anchors 4 with bifurcated tips are protruded from the outer surface of one end having the extension piece 2', and the entire structure is made of synthetic rubber or aluminum with high moisture permeation resistance and excellent corrosion resistance. It is made of alloy or stainless steel.

As shown in FIG. 2, the water stop plate of the above embodiment is attached to the lower part of the inner wall of the relatively short parapet 10. As shown in FIG. 11
Temporarily fix it to the formwork 17 with nails 18, etc., and then pour concrete so that the extension piece 2' becomes the inner wall surface of the parapet 10.

Fixedly installed on the parapet IO. In this way, several parallel concave grooves 3 are formed on the lower surface of the cap 11 downward and perpendicular to the extending direction of the cap 11. Then, the rising upper end of the waterproof layer 12 is inserted into the concave groove 3 on the one end side having the extension piece 2' and filled with mortar 14, and furthermore, bricks 13 are piled up inside with mortar 14 to form the horizontal substrate 1. A waterproof layer presser 15 is formed up to the lower surface. In the parapet 10 formed in this way, rainwater is blocked by the concave @ 3 and the hanging piece 2 on the back of the wing, and falls onto the floor without running through the back of the wing. In addition, the waterproof layer 12
Since the upper end is embedded in the downward groove 3 on the one end side,
Even if a gap or crack is created between the waterproof layer retainer 15 and the lower surface of the cap 11, rainwater will not penetrate to the upper end of the waterproof layer 12.

Next, the second embodiment shown in FIG. 4 is a water stop plate used for a tall parapet 10', in which the width of the horizontal board 1 is narrowed and the hanging pieces 2 are only two pieces at both ends. A concave groove 3 is provided, and an extension piece 2'' that slopes diagonally and hangs downward is integrally molded under one of the lowering pieces 2 as in the first embodiment, and the upper surface of the horizontal board 1 and the extension piece 2 are integrally molded. A large number of anchors 4 having an inverted triangular cross-sectional shape are continuously formed in the longitudinal direction on the outer surface of one end side having a diameter 2'.As shown in FIG. A groove 3 that opens diagonally downward is provided on the inner wall surface of an appropriate height.The upper end of the waterproof layer 12 is inserted into the groove 3 and filled with mortar 14.
Furthermore, the entire parapet 10'' is covered with a waterproof coating 16, so that even if the waterproof coating 16 on the upper part of the parapet 10' is cracked, rainwater will not penetrate beyond the waterproof layer 12 into the frame. .

Next, the third and fourth embodiments shown in FIGS. 5 and 6 are buildings having a waterproof layer 12 on the outside wall 20 of the building frame with porcelain tiles, waterproof mortar, or resin-based spray paint. In this example, the water stop plate according to the present invention was fixed to the back side of the eaves 21 that protruded outward from the upper end of the outer wall 20 during the building frame, and the water stop plate was fixed to the outside surface of the parapet 10 and the eaves 21. Rainwater flowing down the raised bottom of the lower end is blocked by the plurality of lowering pieces 2 and grooves 3, and the waterproof layer 12 of the outer wall 20 is protected.

〔Effect of the invention〕

As described above, the water stop plate at the end of the waterproof layer according to the present invention blocks rainwater with the lower piece and the downward groove, so no rainwater penetrates into the back side of the upper end of the waterproof layer, which improves the durability of the building frame. There is no damage to the material, and it can be installed simply by temporarily fixing it to the formwork when constructing the framework of a parapet or eaves.Furthermore, since the grooves, which can easily cause strength problems, are formed with the inventive material, it is durable. It's also aesthetically pleasing.
