[Structure] In a sealing material 16 that covers joints such as gaps in wall surfaces of buildings and is attached to wall surfaces, etc., the sealing material 16 is formed in advance to a width that covers the joints 14, and the joint surfaces 16A and 16B at both ends are inclined end surfaces. Alternatively, it is characterized in that it is formed on a non-linear end face to increase the joint area of the end portion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint sealing material.

[0002]

[Prior art]

 Conventionally, a construction method has been adopted in which a paste-like amorphous sealing material is filled in the gaps between various members, the gaps between the building frame and the sash, the concrete joints, and the like. In this case, since the sealing material is in the form of an amorphous paste, after the filling, a curing period is allowed to cure and the sealing is completed. The sealing material also serves as a cushioning material for waterproofing and airtightness, or for absorbing expansion and contraction of the used member. Silicone, urethane, polysulfide, etc. are used as the main component of the sealing material.

[0003]

[Problems to be solved by the device]

 However, as described above, the sealing method in which the paste-like sealing material is filled at intervals requires a curing period until the paste-like sealing material is solidified. In particular, when the construction period is limited, sufficient curing may not be possible and the sealing function may deteriorate. Further, if dust or the like adheres to the surface of the sealing material or the surface is scratched during the time until the sealing material filled in the gap dries, it is not preferable in appearance. In addition, if the paste-like sealing material adheres to the surrounding members and becomes dirty, or if the surface of the sealing material becomes uneven due to air bubbles, the commercial value will be impaired. In addition, on-site sealing has the disadvantage that it is difficult to calculate the process because the efficiency of the finished product varies greatly depending on the skill of the worker. Therefore, a method of simply covering the gap between the walls and the gap between the building frame and the sash with a standard product can be considered, but in this case the sealing material has a specified length, so how should the seam be made? The question is whether to do it or not. Then, this invention aims at providing the sealing material of the joint which can raise the strength of a joining part.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has the following configuration. That is, in a sealing material that is affixed to cover joints such as gaps between structural members such as buildings and civil engineering structures, it is formed to have a width that covers joints in advance, and the joint surfaces of both ends are inclined end surfaces or It is characterized in that it is formed on a non-linear end face to increase the joint area at the end.

[0005]

[Action]

 The operation will be described. A sealing material is attached so as to cover the joints on the wall surface of a building, and the end faces to be joined are attached with an adhesive or the like. In this way, the joint area of the joint surface at both ends is increased, and the joint surface exists in a direction different from the direction in which the joint is deformed. Does not come off.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a front view showing a state in which a sealing material is provided on the joints of the body. FIG. 2 is a cross-sectional view of the joint portion of the sealing material. Joints 14 are present on the skeleton 12. The joint 14 is generally filled with a sealing material from the outside and waterproofed. The sealing material 16 of this embodiment is sufficiently wider than the width of the joint 14 and has a predetermined length. The one end surface 16A of the sealing material 16 is composed of horizontal portions 16a and 16b having different heights and an inclined portion 14c that connects the horizontal portions 16a and 16b at an angle. On the other hand, the other end surface 16B of the sealing material 16 is formed in a shape that fits into the one end surface 16A.

Since the sealing material 16 is attached so as to straddle the joint 14, the sealing material 16 is attached after the adhesive 18 is applied to the edge of the skeleton 12 with the joint 14. In order to connect the other sealing material 16 to the attached sealing material 16, the adhesive 20 is applied to one end face 16A of the attached sealing material 16 and the other sealing material 16 is applied to this one end face 16A. The end faces 16B are abutted on each other and attached to the body 12. As described above, before the sealing material 16 is attached to the skeleton 12, a pretreatment is performed. For example, an inspection of the size of the joint 14, the type of coating on the inner surface of the joint 14, the lack of the joint 14, and the like, and the degree of drying of the base are performed. In addition, the edge of the frame 12 with the joint 14 is cleaned and inspected for dust, oil, rust, and other mortar.

In the embodiment shown in FIG. 1, even if the joint 14 is opened in the left-right direction in the drawing, since the adhesive surface does not exist in a straight line in the direction in which the joint 14 is opened, only the adhesive 20 is stretched. Instead, the sealing material 16 also absorbs the elongation. For example, as shown in FIG. 5, when the layer of the adhesive 20 exists linearly in the width direction (opening direction of the joint 14), when the joint 14 tries to open in the left-right direction, it follows that. The sealing material 16 also extends to the left and right, but the layer of the adhesive material 20 that is linear in the width direction has a different elongation rate from the sealing material 16, and only the layer of the adhesive material 20 that has a relatively low elongation rate breaks without stretching. There is a risk. However, in the embodiment of FIG. 1, when the joint 14 is opened in the horizontal direction in the drawing, the layer of the adhesive 20 and the sealing material 16 are always present in the opening direction of the joint 14 (dotted line X in FIG. 1). , Y, and Z), even if the elongation rate of the adhesive material 20 for adhering the sealing material 16 is small, it is absorbed by the sealing material 16.

The shape of the one end surface 16A and the other end surface 16B of the sealing material 16 does not have to be the shape of the above-mentioned embodiment, and the point is to increase the joining area for joining the one end surface 16A and the other end surface 16B of the sealing material 16. Just do it. For example, as shown in FIG. 3, it comprises horizontal portions 16a, 16b having different heights and a vertical portion 16d vertically connecting the horizontal portions 16a, 16b. Further, as shown in FIG. 4, the one end surface 16A and the other end surface 16B of the sealing material 16 may be an oblique joint surface.

The sealing material 16 may be in a paste-like semi-dry state on the adhesive surface side covering the joint 14, and may be in a dry state on the surface side. That is, the sealing material 16 has a hardening gradient in the thickness direction. For this reason, it is necessary to cover the paste-like adhesive surface side of the sealing material 16 with release paper or the like so as not to dry it. By doing so, the construction work on site is extremely easy. Although various explanations have been given with reference to the preferred embodiments of the present invention, the present invention is not limited to the above embodiments, and many modifications can be made without departing from the spirit of the invention. Is.

[Effect of device]

 The sealing material according to the present invention has the following remarkable effects. (1) Since the area of the joint surface at the end of the sealing material is large and is larger than the area cut in the width direction of the sealing material, sufficient strength can be secured at the joint portion. (2) Therefore, peeling of the joint portion of the sealing material can be prevented. (3) In addition, even if the joint part is deformed and a force is applied to the joint part of the sealing material, the adhesive material layer does not exist linearly in the width direction of the joint, so that the sealing material absorbs the deformation of the joint. Become.
