In this state, as shown in FIGS. 3 and 4, the outer peripheral surface of the exposed body portion 2 is flush with the outer peripheral surface of the building member A ₁ , so that the appearance of this portion is enhanced and the hollow seal material S Each fitting portion 3 provided at the center of the longitudinal direction of ₁
To be fitted to the inlet portion of each hollow portion of the two building elements A ₁ to be connected, to stabilize the state the fitting of the hollow sealing member S ₁ for each building element A _1.

When the hollow seal material S ₁ is fitted in the hollow portion of the building member A ₁ , the core material C ₁ is fitted in the hollow portion, and the hollow seal material S ₁ is attached to the hollow portion side. Since it is not deformable, as shown in FIG. 9, the tip portion of each annular seal lip 4 is elastically deformed and the inner peripheral surface 10 (FIG. 8 and FIG. 8) of the hollow portion of the building member A _{1 is} deformed. (See FIG. 9), the connecting portions of the two building members A ₁ are overlapped and sealed. In the first embodiment, a cutout 1a is provided at the bottom of one part of the main body ₁ of the hollow seal material S ₁ which is divided into two parts in the longitudinal direction, and the seal lip 4 of this part is missing. However, since the position is at the bottom of the building member A ₁ , the sealing property is hardly affected.

A pair of bolt fittings 9 are provided in the longitudinal direction at the bottom of the building member A ₁ , and the heads 8a of the connecting bolts 8 are fitted to the bolt fittings 9 in a hanging state. ing. As shown in FIG. 2 and FIG. 3, a connecting plate portion 6a constituting a mounting portion 6 of the core material C ₁ via four connecting bolts 8 in which a head portion 8a is fitted to the bolt fitting body 9 And the building member A ₁ are integrally connected. The connecting bolt 8 is
It is inserted into the long hole 6c provided in the connecting plate portion 6a. Therefore, in the first embodiment, the building element A ₁ of two said are connected together via a core material C ₁ needed to seal the connection of building elements A ₁ of two, Two building members A ₁
There is an advantage that the connection can be made at the same time as the sealing of the connection part.

As shown in FIG. 2, the building member A
_A liner fitting body 11, a gasket fitting body 12, etc. are integrally provided on the inclined surface of the outer end provided on the upper surface of ₁ .
The liner 13 and the gasket 1 fitted in these parts
4, the peripheral edge of the window glass G arranged in an inclined state is sandwiched, but this structure itself is not directly related to the present invention.

In addition, the second shown in FIG. 10 to FIG.
The examples serve only to illustrate the sealing principle of the invention. The connecting portion of the rectangular tubular building member A ₂ is sealed by the hollow seal material S ₂ and the core material C ₂ . As shown in FIG. 10, the hollow sealing material S ₂ is entirely formed of an elastic material and has a rectangular tubular shape corresponding to the shape of the inner peripheral surface of the building member A ₂ . Main body 21 of hollow sealing material S ₂
An annular exposed body portion 22 is provided at a central portion in the longitudinal direction of, and fitting portions 23 are provided in a stepped shape on both sides thereof,
Further, a plurality of seal lips 24 are provided in the portion extending from each fitting portion 23 to both ends of the main body portion 21. In the hollow portion of the hollow seal material S _{2 having} such a shape, a rectangular cylindrical core material C
₂ is fitted.

Then, as shown in FIG. 11, one part of the hollow seal material S _{2 which} is divided into two parts at the central part in the longitudinal direction is fitted into one hollow part of the _two building members A ₂ , and
The other part is fitted into the other hollow part of the _two building members A ₂ . Thus, the hollow sealing member S with the end faces of the building element A ₂ abuts against the end faces of the exposed body section 22 provided in _2, the hollow sealing member S ₂ each fitting portion 23 provided in
Is fitted into the entrance of the hollow portion of each building member A ₂ (see FIGS. 12 to 14). Just as in the first embodiment, the hollow sealing material S ₂ cannot be deformed to the hollow portion side because the core material C ₂ is fitted in the hollow portion, so that the hollow sealing material S ₂ cannot be deformed. _{When 2} is fitted into the hollow portion of the building member A ₂ , each seal lip 24 provided on the outer peripheral surface of the main body portion 21 elastically deforms to elastically contact with the inner peripheral surface 30 of the building member A ₂ so that two The connecting portion of the building member A ₂ is multiply sealed by a plurality of seal lips 24.

As described above, according to the present invention, by making the outer shape of the hollow sealing material correspond to the shape of the hollow portion of the building member,
The present invention is not limited to the hollow building members A ₁ and A ₂ described above, and can seal the connecting portions of various building members. Although the core material is hollow in any of the above-described embodiments, it may be solid.

[0018]

According to the present invention, a plurality of seal lips provided on a hollow seal material are constructed by fitting a hollow seal material having a core material fitted in the hollow portion into each hollow portion of two building members. Since it has a structure in which it is elastically contacted with the inner peripheral surface of the member and seals in a dry type, unlike a wet type seal structure that uses a sealing material, it is possible to maintain high sealing performance for a long period of time and deteriorate due to aging. In addition, the time for curing and curing is unnecessary, and the construction period can be shortened.
