Description

  The present invention relates to a water stop staple used for fixing a lath to a base material constituting a wall structure and a wall structure using the water stop staple.

  Japanese Patent Laying-Open No. 2004-293042 (Patent Document 1) describes a wall structure in which a moisture-permeable waterproof sheet is stretched by driving staples on the outdoor side of a base material.

In this wall structure, waterproofing of the base material is realized by a moisture-permeable waterproof sheet stretched by staple driving. However, since the insertion hole is formed in the moisture-permeable waterproof sheet by driving the staple, there is a possibility that moisture penetrates between the leg portion of the staple and the moisture-permeable waterproof sheet between the insertion hole.
JP 2004-293042 A

  The present invention has been made in view of the above-described problems existing in the prior art, and the object of the present invention is to provide a leg portion of a staple that has been driven into an object and the leg portion that has been driven. An object of the present invention is to provide a water-stopping staple that prevents moisture from the outside from penetrating between the insertion hole of the formed object and a wall structure using the water-stopping staple.

The still water staple of the present invention that achieves the above object is
A staple having a water stop,
The water stop portion is in a state of being externally fitted to each leg portion of the staple,
Of the tip side portion of the water stop portion, the portion surrounding at least each leg portion is made of an elastic material that can press-contact the surface of the object in a watertight manner when the staple is driven into the object,
In a state in which the staple is driven into the object and the tip side portion of the water stop portion is in pressure contact with the surface of the object, the water stop portion and the staple are watertight.

  When this water-stopping staple is driven into an object, a portion made of an elastic material that surrounds each leg portion of the water-stopping portion that is externally fitted to each leg portion of the staple is formed on the surface of the object. Weld in a watertight manner. In this state, the water stop portion and the staple are watertight.

  Therefore, it is possible to prevent moisture from the outside from penetrating between the leg portion of the staple driven into the object and the insertion hole of the object formed by driving the leg portion.

  In addition, a water stop part shall consist of rubber-like elastic materials.

  In the water-stopping staple of the present invention, an integral water-stopping member made of a rubber-like elastic material is externally fitted to both leg portions of the staple, and at least the tip side portion of the portion surrounding each leg portion constitutes the water-stopping portion. It is preferable to do.

  The pressing of the water-stopping member toward the object by the staple in the state of being driven into the object cannot always be said to be uniform in the circumferential direction around the legs of the staple, based on the shape of the staple. Since the water-stopping member made of rubber-like elastic material is integrated, the deformation of the entire water-stopping member is suppressed, and the pressure contact with the surface of the object at the tip side of the water-stopping part is made as even as possible in the circumferential direction. It is possible to perform the watertight pressure contact with respect to the surface of the object of the portion made of an elastic material surrounding each leg portion in the tip side portion of the water stop portion.

  In this water-stopping staple, in the state where the staple is driven into the object and the tip side portion of the water-stopping portion is in pressure contact with the surface of the object, the connecting portion that connects both the leg portions of the staple serves as the water-stopping member. It can be pressed to the side.

  In this case, in a state where the staple is driven into the object and the tip side portion of the water stop portion is in pressure contact with the surface of the object, the connecting portion that connects both the leg portions of the staple presses the water stop member toward the object side. Therefore, the deformability of the entire water stop member can be further suppressed, and the pressure contact with the surface of the object of the tip side portion of the water stop portion can be equalized in the circumferential direction. Among these, the watertight pressure contact with the surface of the object of the portion made of an elastic material surrounding each leg portion can be more reliably performed.

  In addition, these water-stopping staples are opened in the portion between the two leg portions of the staple in the tip-side portion of the water-stopping member in the direction orthogonal to the surface constituted by the staple connecting portion and the leg portion. It is preferable to have a groove-shaped part.

  In this case, since the cross-sectional area (cross section parallel to the surface of the object) is reduced by the groove-like portion on the side of the water stop member that is in pressure contact with the object, deformation of the tip side portion of the water stop portion is facilitated and pressure contact A pressure increases and the watertightness between a target object and a water stop part improves. Further, by positioning the lath linear member or the like to be fixed to the object with staples in the groove-like portion, the wire or the like can be reliably fixed without impairing the water-stopping property.

  Further, the still water staple according to the present invention has a pressing portion made of a rigid material fitted to the base side of both legs of the stable, and a pair of the pressing portions of the both legs of the stable on the tip side of the pressing portion. It is preferable that the water stop portions are respectively fitted.

  In this case, in a state where the staple is driven into the object and the tip side portion of the water stop portion is in pressure contact with the surface of the object, the connecting portion that connects both the leg portions of the staple is one pressing portion made of a rigid material. The pair of water stop portions respectively fitted to the both leg portions of the staple are pressed against the object side, so that the pressure contact with the surface of the object at the tip side portion of both water stop portions is equalized. It is possible to make the watertight pressure contact with the surface of the object of the portion made of an elastic material surrounding each leg portion of the tip side portion of the water stop portion even more reliably.

The wall structure of the present invention is a wall structure comprising a base material, a waterproof sheet covering the base material, and a lath fixed by staples driven into the base material from the waterproof sheet,
The staple is the waterstop staple according to any one of claims 1 to 5, and is made of an elastic material that surrounds each leg portion of the distal end side portion of the waterstop portion that is externally fitted to each leg portion of the staple. This portion is characterized in that it is pressed against the surface of the waterproof sheet in a water-tight manner, and a water-tight shape is formed between the water stop portion and the staple.

  In this wall structure, moisture from the outside is prevented from penetrating between the leg portion of the staple for fixing the lath to the base material and the insertion hole of the waterproof sheet by the leg portion. It is prevented that the waterproof function of the sheet is impaired.

  According to the water-stopping staple of the present invention, when the water-stopping staple is driven into an object, it is made of an elastic material that surrounds each leg portion of the tip-side portion of the water-stopping portion that is externally fitted to each leg portion of the staple. This part is in watertight pressure contact with the surface of the object. In this state, the water stop portion and the staple form a watertight state. It is possible to prevent moisture from the outside from penetrating between the insertion hole of the object formed in this way.

  According to the wall structure of the present invention, it is possible to prevent moisture from the outside from penetrating between the leg portion of the staple for fixing the lath to the base material and the insertion hole of the waterproof sheet by the leg portion. This prevents the waterproof function of the waterproof sheet from being impaired.

  Embodiments of the present invention will be described with reference to the drawings.

  1 to 5 show an example of an embodiment of the present invention. FIG. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is a bottom view, FIG. 4 is a right side view, and FIG. It is a use state sectional view.

  The water stop staple W is formed by fitting a water stop member R to a staple S made of a metal wire (a stopper made of a substantially U-shaped wire, not necessarily made of metal).

  The staple S includes a linear connecting portion SC and a pair of leg portions SL extending in parallel in one direction from both ends thereof.

  The water stop member R is a rectangular plate-shaped body made of synthetic rubber (an example of a rubber-like elastic material), and the central part of one side of the square (in this case, the long side) is a groove-like part G having a cross-sectional arc shape. Is formed. The side having the groove-like portion G is the tip side, and the substantially side is the base side.

  Both the leg portions SL of the staple S pass through both end portions in the longitudinal direction from the base portion side to the distal end side in the thickness direction of the water blocking member R (but not limited to this). Before the water-stopping staple W is driven into the base material B (before use), the distal ends of both leg portions SL protrude from the water-stopping member R, and most of the base side is located in the water-stopping member R, and the connecting portion SC is entirely formed. It is a state in contact with or close to the base side of the water stop member R. It should be noted that the connecting portion SC of the staple S before use is in a state where it is in contact with or close to the base side of the water-stopping member R, and that the leading ends of both legs SL protrude from the water-stopping member R. I don't need it.

  The tip side portion of the water blocking member R is separated on both sides in the longitudinal direction by the groove portion G between the both leg portions SL. Both side portions of the groove-like portion G in the water stop member R constitute a water stop portion RP that surrounds each leg portion SL of the staple S.

  In order to fix the lath A to the base material B (an example of the object. In general, the surface of the object is substantially flat) covered with the waterproof sheet P as shown in FIG. When the water-stopping staple W is driven into the base material B from the leading ends of both leg portions SL so that the linear material is positioned in the groove-like portion G, the entire connecting portion SC connecting the both leg portions SL of the staple S and the base The waterproof member R is compressed between the waterproof sheets P covering the material B. As a result, the distal end surface of the water stop member R (that is, each water stop portion RP) surrounding each leg portion SL of the staple S comes into watertight contact with the surface of the waterproof sheet P covering the base material B, and both legs of the staple S The portion SL and the through hole of the water blocking member R through which they penetrate also form a watertight state. Therefore, moisture from the outside is formed between the leg portion SL of the staple S driven into the base material B covered with the waterproof sheet P and the insertion hole of the waterproof sheet P formed by driving the leg portion SL. Is prevented from penetrating. In particular, the groove-shaped portion G reduces the cross-sectional area of the portion of each water stop portion RP that is in pressure contact with the waterproof sheet P, thereby facilitating deformation of the tip side portion of the water stop portion RP and increasing the pressure of the pressure contact. The water tightness between the object and the water stop part RP is improved. Further, since the linear material of the lath A is positioned in the groove-shaped portion G, the lath A can be reliably fixed without impairing the water stoppage due to the pressure contact of the water stop portion RP to the waterproof sheet P.

  Although the water stop member R is made of synthetic rubber, the entire water stop member R including both the water stop portions RP through which both the leg portions SL penetrate is formed integrally, and the water stop member R is waterproofed by the entire connecting portion SC. Since it is pressed against the sheet P, the deformability of the entire water-stopping member R is suppressed, and the distal end surface of the water-stopping member R surrounding each leg portion SL is as circumferential as possible with respect to the surface of the waterproof sheet P. In a state of equalization, it is more reliably pressed in a watertight manner.

  Thus, a base material B, a waterproof sheet P covering the base material B, and a finishing material such as mortar fixed by water-stopping staples W driven on the base material B from the waterproof sheet P are applied. The waterproof function of the waterproof sheet P is impaired by preventing penetration of moisture from the outside between the leg portion SL of the staple S and the insertion hole of the waterproof sheet P formed by the leg portion SL. A wall structure is obtained that is prevented from being damaged.

  FIG. 6 is a front view of another example of the embodiment of the present invention.

  The water stop member R in this case is a pair of cylindrical bodies made of synthetic rubber, and both leg portions SL of the staple S penetrate each water stop member R from the base side in the axial direction to the tip side. In this case, each water stop member R constitutes a water stop portion RP. Before the water-stopping staple W is driven into the base material B (before use), the distal end side of both leg portions SL protrudes from the water-stopping member R, and most of the base side is located in the water-stopping member R, and the connecting portion SC is water-stopping. It is a state in contact with or close to the base side of the member R. It should be noted that the connecting portion SC of the staple S before use is in a state where it is in contact with or close to the base side of the water-stopping member R, and that the leading ends of both legs SL protrude from the water-stopping member R. I don't need it.

  In order to fix the lath A to the base material B (object) covered with the waterproof sheet P, the water stop staple W is placed on both leg portions so that the linear material of the lath A is positioned between the water stop portions RP. When driven into the base material B from the leading end side of the SL, each water-stopping member R is compressed between the connecting portion SC that connects both the leg portions SL of the staple S and the waterproof sheet P that covers the base material B. As a result, the distal end surface of the water stop member R (that is, each water stop portion RP) surrounding each leg portion SL of the staple S comes into watertight contact with the surface of the waterproof sheet P covering the base material B, and both legs of the staple S The portion SL and the through hole of the water blocking member R through which they penetrate also form a watertight state. Therefore, moisture from the outside is formed between the leg portion SL of the staple S driven into the base material B covered with the waterproof sheet P and the insertion hole of the waterproof sheet P formed by driving the leg portion SL. Is prevented from penetrating.

  FIG. 7 is a front view of still another example of the embodiment of the present invention.

  In this case, one thin plate-like or rod-like pressing portion E made of a rigid material (for example, synthetic resin, metal, ceramics, etc.) is fitted to the base side of both legs SL of the stable S, and the stable S A pair of cylindrical water-stop portions C made of synthetic rubber joined to the pressing portion E is fitted to the distal end side of the pressing portion E in both leg portions SL. That is, both leg portions SL of the stable S pass through both end portions of the pressing portion E, respectively, and further pass through a pair of cylindrical water-stop portions C in the axial direction. The water stop portion C is joined to the pressing portion E on the entire surface on the base end side. In addition, as for this press part E and the water stop part C, it is desirable to join like this example.

  When the still water staple W is used, in the state where the staple S is driven into the base material B and the tip side portion of the water stop portion C is in pressure contact with the surface of the base material B, the connection is made to connect both the leg portions SL of the staple S. The part SC presses the pair of water stop parts C respectively fitted to the leg parts SL of the staple S to the base material B side as uniformly as possible through one pressing part E made of a rigid material. Therefore, the pressure contact with the surface of the base material B of the front end side portions of the both water stop portions C can be equalized, and the elastic member surrounding each leg SL among the front end side portions of the water stop portions C is made. The watertight pressure contact with the surface of the partial base material B can be more reliably performed.

  It should be noted that the dimensions, number, material, shape, relative arrangement, etc. of the component parts in the description of the above embodiments are limited to the scope of the present invention unless otherwise specified. It is not intended to be limiting, but merely an illustrative example.

  For example, in the still water staple according to the present invention, the tip side portion of the water stop portion does not necessarily need to be in close contact with each leg portion, and is in a state of surrounding each leg portion at an interval, for example, in an annular shape. It can also be pressed. In this case, in a state in which the staple is driven into the object and the front end side portion of the water stop portion is in pressure contact with the surface of the object, for example, the water stop portion and the staple are watertight in the base side portion. is required.
