Description

The present invention relates to an attachment structure for a plate material using a zipper gasket for building for fixing a plate material such as a glass plate or an outer wall plate in a building.

  Conventionally, as shown in FIG. 4, a rubber body 5 is formed with a plate material fitting groove 2 into which an end of a glass plate (plate material) 1 is fitted and a zipper groove 4 into which a zipper 3 is fitted. An architectural zipper gasket is known in which an anchor 8 that is fitted into the mounting groove 7 of the concrete portion 6 is projected (for example, Patent Document 1).

In this construction zipper gasket, the anchor 8 is fitted into the mounting groove 7 of the concrete portion 6, so that a plurality of anchor lips 9 formed on both the inner and outer sides of the anchor 8 are elastically pressed against the inner surface 10 of the mounting groove 7. Then, the rubber body 5 is fixed to the concrete portion 6, and the under lip (contact portion) 11 on the inner side of the rubber body 5 is brought into contact with the surface 12 on the inner side in the vicinity of the mounting groove 7 in the concrete portion 6. An under lip (contact portion) 13 on the external OUT side of the main body 5 is brought into contact with the surface on the external OUT side 14 near the mounting groove 7 in the concrete portion 6. Further, by inserting the zipper 3 into the zipper groove 4 of the rubber main body 5, the portion near the plate material insertion groove 2 in the rubber main body 5 is pressed against the side surface of the glass plate 1, and the glass plate 1 is fixed to the rubber main body 5. At the same time, the end of the glass plate 1 is sealed.

A structure is disclosed.

Japanese Patent Laying-Open No. 2004-036805 (FIG. 1) Japanese Utility Model Laid-Open No. 4-130611 (Summary, FIG. 1)

  By the way, in the zipper gasket for construction, from the viewpoint of the design of the frame window part (window part such as the outer wall of the building), the distance L1 from the groove width center of the plate material fitting groove 2 to the outer end face 6A of the concrete part 6 is set. There is a demand for reducing the size of the glass plate 1 as close as possible to the outer end surface 6A of the concrete portion 6 and finishing the entire outer wall surface including the window portion as flat as possible.

  However, if the distance L1 is decreased in order to bring the glass plate 1 closer to the outer end surface 6A of the concrete portion 6, the mounting groove 7 is located on the groove width center line of the plate material fitting groove 2 when the distance L1 is reduced. Similarly, the distance L2 from the center of the groove width to the outer end surface 6A of the concrete portion 6 is also reduced.

  Since the concrete part 6 is composed of a precast concrete panel formed in a window frame shape, shrinkage occurs during solidification in the process of molding the concrete part 6, and this shrinkage causes a corner part 7 </ b> A of the mounting groove 7. , 7B, stress concentration occurs. Further, when the distance L2 becomes small and the distance L3 from the outer corner portion 7A to the outer end surface 6A of the concrete portion 6 becomes too small, the desired strength of the edge portion 7X outside the mounting groove 7 is obtained. Otherwise, there is a risk that a crack may occur from the corner portion 7A toward the end edge portion 7X, or the end edge portion 7X may fall off. Accordingly, the minimum values of the distances L2 and L3 are restricted in order to secure the strength of the edge portion 7X and prevent the occurrence of cracks and chipping. For this reason, the conventional architectural zipper gasket having a cross-sectional structure in which the mounting groove 7 is provided directly above the anchor 8 satisfies the design requirement of bringing the glass plate 1 as close to the outer end surface 6A of the concrete portion 6 as possible. I can't.

  On the other hand, the distances L2 and L3 are maintained at the minimum value or more by making the cross-sectional structure in which the distance L1 is made smaller by biasing the position of the plate material mounting groove 2 to the outside OUT side than the position of the anchor portion 8. Even if it is possible to prevent the edge 7X from cracking or chipping in the state and the glass plate 1 is brought close to the outer end surface 6A of the concrete portion 6 to satisfy the design requirements, The balance of the cross-sectional structure suitable as a gasket and the stability on the glass plate 1 support are impaired.

On the other hand, in the conventional structure in which one anchor portion 8 is fitted and fixed in one mounting groove 7, when a positive pressure P1 on the external OUT side is loaded on the glass plate 1, the external OUT side When the contact portion 13 may be deformed so as to be turned up from the surface 14 on the outside OUT side in the vicinity of the mounting groove 7 in the concrete portion 6 and on the contrary, negative pressure P2 on the IN side is applied to the glass plate 1 The inner IN side contact portion 11 may be deformed so as to be turned up from the inner IN side surface 12 in the vicinity of the mounting groove 7 in the concrete portion 6. The water stoppage is impaired and intrusion of rainwater or the like is caused.
In addition, in the mounting structure of the above-mentioned patent document 2, it is made to approach the outdoor side surface of an outer wall panel using an embedded metal. However, in such a structure, an embedded metal must be used in addition to the gasket. It becomes complicated.

Therefore, the object of the present invention is to bring the plate material as close to the outer end surface of the concrete portion as possible and satisfy the design requirements of the frame window portion, while ensuring the support property of the plate material, It is providing the attachment structure of the board | plate material using the zipper gasket for construction which can raise.

  In order to achieve the above-mentioned object, a building zipper gasket according to the present invention has a rubber body formed with a plate material fitting groove into which an end portion of a plate material is fitted and a zipper groove into which the zipper is fitted, and the rubber body is made of concrete. An anchor to be fitted in the mounting groove of the portion is protruded, and the anchor is fitted in the mounting groove, so that the rubber body is fixed to the concrete portion, and on both the inside and outside of the anchor The contact portion of the rubber main body is in contact with both inner and outer surfaces of the concrete portion in the vicinity of the mounting groove, and the zipper is inserted into the zipper groove of the rubber main body, thereby inserting the plate material in the rubber main body. In an architectural zipper gasket in which a portion in the vicinity of a groove is pressed against a side surface of a plate material, the anchor is located at a position separated in the thickness direction of the plate material as a first anchor. And over portion and the second anchor portion is provided generally parallel to each other.

  According to this building zipper gasket, the first anchor portion and the second anchor portion are provided substantially in parallel with each other, so that the position of the plate material fitting groove is biased toward the outer OUT side anchor portion. Even if the distance from the center of the groove width of the plate material fitting groove to the outer end surface of the concrete part is reduced, the balance of the cross-sectional structure and the plate material support suitable as a zipper gasket for construction can be achieved even if the plate material is brought closer to the outer end surface of the concrete part The upper stability can be maintained, and the plate material is brought close to the outer end surface of the concrete portion, and the entire outer wall surface is finished to be almost flat, thereby satisfying the design requirements of the frame window portion.

In addition, since the two anchor portions are provided, the cross-sectional area of each of the two anchor portions is reduced as compared with the structure having only one anchor portion, and the groove width of the mounting groove is reduced. And / or the depth of the groove can be set small. Therefore, even if the distance from the center of the groove width of the mounting groove to the outer end surface of the concrete portion is reduced, the distance from the corner portion outside the mounting groove to the outer end surface of the concrete portion is ensured corresponding to the smaller groove width. Thus, the strength of the edge portion outside the mounting groove can be ensured. Further, if the depth of the groove is reduced, it can be ensured without reducing the strength of the edge portion.
Further, in the present zipper gasket for construction, it is not necessary to separately provide a member such as an embedded hardware for supporting the gasket on the concrete portion, the mounting structure is simplified, and the construction can be performed easily.

In this architectural zipper gasket around the plate Hamakomimizo, provided with the first anchor portion inboard, Ru providing the second anchor portion outboard.

  In this case, since the two anchor portions are provided at such positions, the deformation of the gasket can be suppressed even when a positive pressure or a negative pressure is applied to the plate material. That is, it is possible to suppress the deformation such that the contact portion turns up and floats from the surface near the mounting groove in the concrete portion, thereby increasing the water stoppage.

  By doing in this way, a board | plate material can be brought close to the outer end surface of a concrete part, and the request | requirement on a design can be satisfied. Also, by providing two mounting grooves, the groove width and / or depth of each of the two mounting grooves is set to be smaller than that of a structure in which only one mounting groove is provided. So, even if the distance from the groove width center of the mounting groove to the outer end surface of the concrete part is reduced and the plate is brought closer to the outer end surface of the concrete part, the corner part outside the mounting groove corresponds to the smaller groove width. Increases the distance from the outer end surface of the concrete part to improve the filling of the concrete into the relevant part (the part from the outer corner of the mounting groove to the outer end face of the concrete part) when manufacturing a concrete panel And the intensity | strength of an outer edge part can be ensured similarly to a mounting groove. Moreover, if the depth of the groove is reduced, the strength of the edge portion can be further ensured.

  Furthermore, in the mounting structure of the present plate material, a drainage passage that opens the interior of the plate material insertion groove to the outside of the concrete portion may be provided in the rubber body and the concrete portion, and a hose may be inserted into the drainage passage.

  As described above, according to the present invention, since the first anchor portion and the second anchor portion are provided substantially parallel to each other, the position of the mounting groove is biased toward the anchor portion on the external OUT side. By providing it, the plate material can be brought close to the outer end surface of the concrete part to satisfy the design requirements, and the balance of the cross-sectional structure suitable as a zipper gasket for construction and the stability on the plate material support can be maintained. it can. Moreover, when a positive pressure or a negative pressure is applied to the plate material, it is possible to suppress the deformation such that the contact portion of the rubber main body is turned up from the surface in the vicinity of the mounting groove of the concrete portion, thereby increasing the water-stopping property.
