Description

{Water Stop Plate for Concrete Walls}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waterproof plate for preventing intrusion of water from outside against a concrete concrete wall. In particular, the present invention relates to a watertight plate that is embedded in a concrete wall to prevent water from intruding from one side wall surface of the concrete wall to the opposite side wall surface.

Fig. 1 and Fig. 2 show the numerical values introduced in Korean Patent Registration No. 10-0975649.

1 and 2 includes a body portion 20, a lower end portion 50, a waterproof portion 40, and a side support portion 30.

A protrusion 22 is formed at one end of the body 20 and an engaging groove 25 is formed at the other end of the protrusion 22. The protrusion 22 is fixed to the protrusion 22, And it is installed for waterproofing of the concrete laminated boundary.

The lower end portion 50 is inserted into and fixed to the inner side of the first-stage concrete laminated portion 71 which is extended to the lower side of the predetermined length and filled between the dies 60 before hardening.

The waterproof portion 40 is formed by extrusion molding integrally with the body portion 20 and extending upward to be disposed across the lower portion of the two-stage concrete laminated portion. Stage concrete laminating unit (not shown) is installed between molds (not shown) newly installed on both sides of the first-stage concrete laminating unit 71 in a state where the lower end portion 50 is inserted and fixed in the first-stage concrete laminating unit 71, At this time, the waterproof portion 40 is disposed upright on the lower portion of the two-stage concrete laminated portion.

The above-mentioned conventional waterproofing plate may have a problem that the fastening between the waterproofing plates is interrupted between the waterproof plate and the waterproof plate during the weak concrete wall curing process.

In addition, there is a problem in that water can penetrate between the water surface plate and the water surface plate, failing to achieve a full index function.

It is an object of the present invention to provide a new structure of a water resistance plate capable of effectively preventing intrusion of water at a portion thereof while further strengthening the fastening between the water resistance plate and the water resistance plate.

The water resistance plate of one embodiment includes a body portion, an insertion portion, and a fastening groove portion.

The body portion includes a lower body portion and an upper body portion. The lower body part is embedded in the lower layer concrete wall, and the upper body part is embedded in the upper layer concrete wall.

The interstices between the lower concrete wall and the upper concrete wall allow water to penetrate from the outside of the concrete wall to the interior, preventing the penetration of water because the body is embedded between the layers.

The lower body part is inserted before the lower concrete wall is hardened and is buried as the lower concrete wall is hardened. Then, an upper layer of concrete wall is formed. As the upper layer of concrete wall is hardened, the upper body portion is embedded in the upper layer of concrete wall.

The body portion may have a thin plate shape, and may include ribs formed continuously along the longitudinal direction on at least one side of both sides thereof. These ribs may be formed on each side of the body portion at regular intervals from top to bottom.

The insertion portion is integrally formed continuously in the longitudinal direction at one end of the body portion. The insert also has a plate shape, which may be made of the same height and thickness as the height and thickness of the body portion. Or may be plate-shaped and made to a height and thickness less than the height and thickness of the body portion.

The side surface of the insertion portion can also be formed in the same manner as the above-described ribs. And, at least one rib may be continuously formed from the body portion to the insertion portion.

And the other end of the body portion is integrally formed with a fastening groove portion having an insertion groove into which the insertion portion can be inserted. The inserting portion of the other diaphragm plate is inserted and fastened to the fastening groove portion, so that the diaphragm plate and the diaphragm plate are fastened together.

When a rib is formed in the insertion portion, the insertion groove includes a groove shape corresponding to such a rib.

The height and thickness of the fastening groove portion may be equal to or greater than the height and thickness of the body portion.

The cross-sectional area of the insert can be more than 2/3 of the cross-sectional area of the body, and since it is inserted in such a wide range, not only the fastening force between the steel plate and the steel plate becomes strong, but importantly, Increase.

Particularly, the structure of the plate-like insertion portion extending upward and downward at the boundary portion between the lower body portion and the upper body portion, which can be called the boundary of the layer, and the fastening groove portion into which such insertion portion is inserted, And is very effective in preventing water intrusion.

At least one projection may be formed on one side of the insertion portion, and a latch groove may be formed on the inner side surface of the coupling groove, that is, the inner surface of the insertion groove, into which the projection is inserted while the insertion portion is inserted. At this time, the thickness of the insertion portion including the projection may be larger than the insertion groove thickness of the coupling groove portion. Thus, when the insertion portion is inserted into the insertion groove, the insertion groove can be resiliently opened, and the insertion groove can be restored to its original shape when the projection is inserted into the latching groove.

On the other hand, a water expansion index material can be installed in the insertion groove of the fastening groove portion.

Water outside the concrete wall may enter through the space between the inner surface of the insertion groove and the insertion portion. At this time, the water expansion index material expands and blocks the gap, thereby further enhancing the index function.

The water resistance plate of the embodiment of the present invention performs an exponential function on the interstices between the concrete walls, achieves a more firm connection between the waterproof plates, and effectively prevents water from entering through the clearance between the waterproof plates and the waterproof plates.

Figures 1 and 2 illustrate the prior art.
3 shows a water resistance plate of an embodiment of the present invention.
Fig. 4 shows how the diaphragm of Fig. 3 is combined with another diaphragm.

3 and 4, a description will be given in detail of the plate of the embodiment.

The diaphragm includes a body portion 130, an insertion portion 150, and a fastening groove portion 160.

The body portion 130 includes an upper body portion 110 and a lower body portion 120. The lower body portion 120 is a portion that is inserted into the upper portion of the lower-layer concrete wall before it is hardened and then embedded together with the solidified concrete wall.

When the lower-layer concrete is hardened, an upper-layer concrete wall is formed. For this purpose, a mold for an upper-layer concrete wall is installed above the lower-layer concrete wall, and the upper body portion 110 is embedded and hardened together with the concrete do.

Since the upper body portion 110 is embedded in the upper-layer concrete wall and the lower body portion 120 is embedded in the lower-layer concrete wall, the penetration of water through the interstices between the upper and lower layers is blocked by the body portion 130.

The lower part of the lower body part 120 is made thinner toward the end, so that it is possible to more easily accomplish the operation of inserting the lower body part 120 into the lower concrete wall.

The insertion portion 150 is formed at one end of the body portion 130 and continuously extends from the body portion 130 in the longitudinal direction thereof. In this embodiment, the insertion portion 150 has a height and a thickness equal to that of the body portion 130 and is continuously extended.

The insertion portion 150 may be formed to be smaller than the height and the thickness of the body portion 130, unlike the present embodiment.

In some embodiments, the height of the insertion portion 150 is less than the height and the thickness of the body portion 130, but the height of the insertion portion 150 may be made three times or more larger than the thickness.

The insertion portion 150 may be formed to have a sufficient height from the boundary between the lower body portion 120 and the upper body portion 110 to the upper portion and the lower portion. Since the interlayer gap will be located in the vicinity of the boundary between the lower body part 120 and the upper body part 110, an exponential function can be effectively performed by extending the upper and lower parts sufficiently.

A plurality of ribs 111 to 112 and 121 to 123 are continuously formed on both sides of the body part 130 along the longitudinal direction. At least a part of the ribs 111, 121, And both sides are continuously extended.

On the opposite side of the insertion portion 150 of the body portion 130, the coupling groove 160 is positioned.

The coupling groove 160 is formed with an insertion groove 161 into which the insertion portion 150 can be inserted.

The insertion groove 161 includes a groove shape corresponding to the ribs 111 to 112 and 121 to 123 so that the ribs 111 to 112 and 121 to 123 of the insertion portion 150 can be inserted.

In this embodiment, the height and thickness of the coupling groove 160 are larger than the height and thickness of the body 130, but when the size of the insertion part 150 is made small, the size of the coupling groove 160 is made small Can be. It is preferable that the inserting portion 150 is formed to be sufficiently long in the vertical direction at the boundary between the lower body portion 120 and the upper body portion 110 in order to effectively achieve the exponential function of the interlayer gap between the walls Do.

The shape of the insertion groove 161 of the coupling groove 160 is the same as the shape of the outer shape of the body 130 or the insertion portion 150. [

A protrusion 151 is formed on a side surface of the insertion portion 150 and a locking groove 162 into which the protrusion 151 can be inserted is formed in the coupling groove 160 .

In this embodiment, the latch groove 162 is formed to pass from the inner surface of the insertion groove 161 to the outer surface of the coupling groove 160.

The thickness of the insertion portion 150 including the projection 151 is larger than the thickness of the corresponding portion of the insertion groove 161 so that the insertion groove 150 is formed in the insertion groove 161 when the insertion portion 150 is inserted into the insertion groove 161 of the fastening groove portion 160. [ And the elasticity of the protrusion 151 is restored to its original thickness as soon as the protrusion 151 is inserted into the latch groove 162. [

In the present embodiment, the water expansion index member 170 is provided in the insertion groove 161. In order to prevent water from entering into the gap in the state where the insertion part 150 is inserted into the insertion groove 161, the water expansion index material 170 may be installed in the insertion groove 161, Strengthen.

The water expansition index material 170 is a material which expands as it comes into contact with water, and its description is well known, and thus a detailed description thereof will be omitted.
