Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of an opening formed by using a sash on an outer wall of a house, and particularly relates to an opening structure that realizes a long life.
[0002]
[Prior art]
In houses using concrete panels (PC panels) or lightweight cellular concrete panels (ALC panels) on the outer wall, use the aluminum sash (building sash) provided for buildings when opening the outer wall. Is common. In particular, in the case where the opening is constituted by the outer wall and the building sash constituting the finished surface as it is, it can be finished by directly applying an atypical seal between them. However, this building sash has a problem that there are few types of products compared to the aluminum sash provided for wooden houses (housing sashes), such as lack of high thermal insulation specifications, and the housing sash for building sashes and residential sashes There is a problem in that the mounting method and the standard for dimension setting are different, and the sash for a house cannot be used for the house as it is.
[0003]
That is, in the sash for a wooden house, the width dimension is set on the basis of the internal dimension of the wooden pillar and is fixed directly to the pillar. On the other hand, in a house using a PC panel or an ALC panel on the outer wall, a sash for a building is used because it is difficult to fix and waterproof the wooden house sash.
[0004]
For this reason, proposals have been made to apply a wooden house sash to a house using a PC panel or an ALC panel on the outer wall. As one of them, an sash and an opening panel composed of a frame that supports the sash and is fixed to a beam constituting the steel frame are provided, and auxiliary frames are installed on the outer sides of the sash frame. There is a technology configured to use a sash that is distributed in the city by fixing and fastening to a frame and a sash frame (for example, Non-Patent Document 1).
[0005]
In the above technique, a frame made of a steel material is fixed to a beam, a supporting steel material is welded to the frame, and an auxiliary frame installed outside the outer peripheral portion of the sash is fixed to the supporting steel material. Therefore, the sash frame and the auxiliary frame installed outside the outer periphery of the sash frame function as a new sash frame, and by fixing this auxiliary frame to the frame, the sash frame is fixed so as to be pressed from the outside. ing. That is, the auxiliary frame functions as an auxiliary to the sash frame and is fixed to the frame by being integrated with the sash frame, and also has a function of finding because it is installed outside the sash frame. Therefore, it is not assumed that the sash is removed while leaving the auxiliary frame, and that the sash and the auxiliary frame are removed later.
[0006]
The auxiliary frame is made of aluminum and has a specification conforming to the specification of the sash frame, and the joint surface between the sash frame and the auxiliary frame is water-stopped with a fixed and non-standard sealing material. In addition, when water-stopping treatment is performed between the auxiliary frame and the outer wall, if the member constituting the outer wall is an ALC panel, fine irregularities are formed on the facet, so that the water-stopping treatment is performed with an amorphous seal material. It is common.

[Problems to be solved by the invention]
When a long life is to be realized in a house constructed by attaching a concrete-type outer wall panel to a steel frame, the aluminum sash achieves a life similar to that of the housing body in the opening constructed using an aluminum sash. There is a risk that it may not be possible. That is, in the aluminum sash, the vertical beam and the horizontal beam are not integrated by welding or the like, and the water stop treatment is performed by placing a sealing material on the contact surface between the vertical beam and the horizontal beam and tightening both. Done. However, as a material characteristic, the sealing material tends to be shorter in durability than the steel frame or the concrete-type outer wall panel.
[0009]
Since the auxiliary frame made of aluminum is basically manufactured based on the same specifications as the aluminum sash, the durability of the sealing material arranged between the vertical frame material and the horizontal frame material is a problem. There is a risk of becoming. When the sealing material between the vertical frame material and the horizontal frame material deteriorates, there is a risk that water may penetrate into the outer wall.
[0010]
For this reason, since the auxiliary frame covers the sash frame in the above house, it is necessary to replace both the aluminum sash and the auxiliary frame at an appropriate time (at least when the seal material reaches the end of life). In addition, when the sash breaks for some reason, when a new sash with improved performance including heat insulation performance is generalized, when changing the opening / closing type, design, color at the time of renovation, etc., it can be replaced I need it.
[0011]
In order to replace the aluminum sash with the auxiliary frame, the auxiliary frame must be removed from the outer wall, and when the auxiliary frame is replaced with the outer wall, the auxiliary frame has an atypical seal with the outer wall panel. There is a problem that both works are very troublesome because the material is applied and water-stopped.
[0012]
An object of the present invention is to provide an opening structure in an outer wall that can exhibit watertightness that can be sufficiently reliable over a long period of time.
[0013]
[Means for Solving the Problems]
In order to solve the above problems, an opening structure according to the present invention is an opening structure in which a sash is attached to a frame body in a concrete-based outer wall of a house, and the sash is an outer periphery of the sash frame. A flange is formed on the part, and the frame body is detachably attached to a coupling surface formed on a side surface for mating with a small edge surface of an outer wall and a sash formed on the inner side perpendicular to the coupling surface. anda mounting surface for the frame, the mounting surface and Togo surface section formed by the rectangular frame-like by welding by contact with each other end of L-shaped member The entire circumference is integrally formed, and a waterproof treatment is performed between the joint surface of the frame body and the edge surface of the outer wall, and the outer peripheral portion of the sash frame is formed on the mounting surface of the frame body. der which the sash mounted on the frame so fitted the flange is detachable .
[0014]
In the opening structure, since the frame body is integrally formed on the entire periphery, it is not necessary to perform a watertight treatment by disposing a sealing material at a connection portion of the members constituting the frame body. For this reason, the frame itself can exhibit high water tightness over a long period of time.
[0015]
In addition, since the frame has a mounting surface and a mating surface, it is possible to mount a sash such as a wooden housing sash using the mounting surface, and waterproof and watertight between the outer wall through the mating surface. Processing can be performed. In particular, since the frame body can exhibit highly reliable watertightness over a long period of time, there is no need for replacement, and good watertight performance can be maintained.
[0016]
In particular, the sash can be detachably attached to the attachment surface provided on the frame. For this reason, it is possible to replace only the sash while maintaining the attachment state of the frame to the outer wall. Therefore, it is possible to easily extend the life of the house by performing maintenance over time.
