Description

  The present invention relates to a waterproofing gasket for a lower part, a sealing structure for an outer wall joint using the same, and a sealing method for an outer wall joint.

  Patent Document 1 listed below discloses a seal structure for an outer wall joint using a fixed gasket. Briefly, a fixed gasket is attached to a horizontal joint formed between the upper end of the lower floor outer wall and the lower end of the upper floor outer wall, and the surface side is filled with an irregular sealing material. ing. The lower end portion of the fixed gasket is a flat surface. After the flat surface is bonded to the upper end surface of the lower floor outer wall, the upper floor outer wall is attached. At this time, the self-weight of the outer wall of the upper floor acts on the hollow seal portion of the fixed gasket and elastically deforms it to obtain a predetermined seal pressure.

  By the way, when building a building with a lower roof part, it takes about one to two weeks until the rain closing work is completed after the roof construction of the lower roof part is done and the joint seal is put out. If there is rainfall during the period, there is a risk that rainwater may infiltrate from the joints on the outer wall of the rising part near the wall of the lower house. For this reason, conventionally, as an example, rainwater is prevented from entering by temporarily stretching a sheet on the outer wall joint, but the work efficiency is lowered.

Therefore, if the outer wall horizontal joint can be easily sealed using a fixed gasket during the above construction period, the work of stretching or peeling the sheet can be eliminated, but the outer wall horizontal joint can be easily sealed. Moreover, it is difficult to ensure good sealing performance. For example, even if it is going to apply the sealing structure of the outer wall joint part described in the said patent document 1, after attaching a lower floor outer wall, a fixed gasket is attached to the upper end part of a lower floor outer wall with an adhesive agent, and an upper floor outer wall is attached after that. It must be attached so that the seal portion of the fixed gasket is elastically deformed by a predetermined amount, which restricts the construction procedure of the outer wall panel and complicates the operation.

As a result, the horizontal joint 98 is closed and sealed by the gasket bodies 106 and 110, and the draining portions 108 and 112 are suspended from the lower ends of the front surfaces of the gasket bodies 106 and 110. The upper end portion of the roofing plate side roofing portion 50A of the roofing 50 is also sealed.

  Next, as shown in FIG. 12C, after the curing is completed, joint sealing work is performed. That is, the lower roof waterproof gaskets 100 and 104 are removed from the horizontal joint 98. The detached waterproofing gaskets 100 and 104 are collected and repeatedly used at the subsequent sites. When hitting joint seals, the roof construction has already been completed. Then, after the rain water drainer 56 and the decorative sheet metal 58 are respectively attached, the irregular sealing material 60 is applied to the horizontal joint 28. Therefore, in the case of this method, the lower roof waterproof gaskets 100 and 104 do not function as a backup material for the irregular sealing material 60, but the lower roof waterproof gaskets 100 and 104 can be used repeatedly. That's it.

  As described above, also in the present embodiment, the upper end portion of the waterproof base material 34 and the upper end portion of the roofing plate-side roofing portion 50A of the roofing 50 are covered by the lower roof waterproof gaskets 100 and 104, as in the first embodiment described above. In addition, since the horizontal joint 98 is sealed by the gasket bodies 106 and 110, rainwater does not enter from the horizontal joint 98 even if there is rain during curing.

  Moreover, by performing construction as in the present embodiment, the lower roof waterproof gaskets 100 and 104 can be mounted after the horizontal joint 98 is formed by the outer wall finishing material 30 and the waterproof base material 34. The outer wall work can be carried out independently of the waterproof gaskets 100 and 104. Therefore, work efficiency is good. Further, since the lower roof waterproof gaskets 100 and 104 can be attached to the horizontal joint 98 from the outdoor side, the work can be easily performed.

  Accordingly, according to the waterproof gasket 100, 104 for the lower roof portion and the sealing structure for the outer wall joint portion using the same and the sealing method for the outer wall joint portion using the same according to the present embodiment, it is possible to carry out the rain finishing work after the outer wall work is completed by a simple work. It is possible to prevent rainwater from entering through the outer wall side joints near the wall of the lower roof 90 during the construction period up to.

  In particular, in the present embodiment, since the lower roof waterproof gaskets 100 and 104 are removed from the horizontal joint 98 after being cured and used repeatedly, cost reduction can be achieved.

  In addition, even if the lower roof portion 116 of the lower roof portion 114 as shown in FIG. 13 is a gable type, the shape of the lower waterproof gasket 104 is a mountain shape in accordance with the shape of the corner portion 120 of the horizontal joint 118. Then, it can be applied in the same way.

[Fourth Embodiment]
Next, with reference to FIG. 14, a fourth embodiment of a waterproofing gasket for a lower part according to the present invention, a sealing structure for an outer wall joint using the same, and a sealing method for the outer wall joint will be described.
