In recent years, reforms that have less economic burden than rebuilding buildings have been reviewed. For example, in addition to renovation of wallpaper and floors, sash reforms that can be expected to improve soundproofing performance and heat insulation performance are also actively implemented. It has become like this.
However, when remodeling the sash, the thickness and spacing of the new sash door to be replaced may be different from those before the renovation that was installed. There is a risk of failure such as not meeting the door-to-door spacing of the door, or the windbreak hitting the end face of the new sash door, and the sash frame must also be of a size that fits the new sash door. The sash frame must be replaced with a new one.
According to the conventional sash installation structure described above, the outer periphery of the sash frame is firmly fixed to the housing around the opening of the building with mortar or the like, so in order to replace the sash frame, the concrete or mortar on the outer periphery is beaten. There is a problem in that work is required, which takes time, money, and noise.
In order to solve such problems, it is possible to leave the installed sash frame as it is and install a new sash frame with a smaller size inside, but in that case, the sash opening area However, it is slightly smaller than the opening area before renovation, and lacks openness, which is unfavorable in terms of aesthetics.

  Accordingly, an object of the present invention is to provide a sash installation structure and a sash that can solve the above-mentioned problems and can easily replace the sash frame while maintaining the openness of the sash opening.

  A first characteristic configuration of the present invention is a sash installation structure in which a sash frame is installed along the inner periphery of a building opening, wherein a base frame is installed along the inner periphery of the building opening, An upper frame member, a lower frame member, and a pair of vertical frame members constituting the sash frame are disposed inside the opening of the sash frame, and each frame member is fixed to the base frame in a disconnected state. By the way.

According to the second characteristic configuration of the present invention, in addition to achieving the above-described operational effects of the first characteristic configuration of the present invention, each frame member is detachably fixed to the base frame. Therefore, each frame member can be removed from or attached to the base frame as necessary. That is, at the time of the sash renovation work as described above, it is possible to replace each frame member with a new one, or to replace only a part of the frame members.
Therefore, it is possible to satisfactorily perform maintenance including sash reform.

  A third characteristic configuration of the present invention is a sash that can be installed along an inner periphery of a building opening, and a base frame that can be installed along the inner periphery of the building opening, and an inner periphery of the opening of the base frame. The sash frame is configured to include an upper frame member, a lower frame member, and a pair of vertical frame members, and the frame members are not connected to each other. In the state of being fixed to the base frame.

According to the third characteristic configuration of the present invention, even when replacing with a new sash frame, for example, remodeling, the work is performed with a simple effort of replacing each frame member while leaving the base frame. be able to.
Therefore, it is not necessary to grind the concrete and mortar on the outer periphery of the frame, and it is possible to reduce the labor for replacing the sash frame, speed up the replacement work, reduce the replacement cost, and prevent the generation of noise accompanying the work.
Moreover, it can prevent that a sash opening becomes narrow and can also maintain the openness of a sash opening.

  Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the parts indicated by the same reference numerals as those in the conventional example indicate the same or corresponding parts.

A base frame 3 is installed along the inner periphery of the building opening 2, and a sash frame 1 is fixed inside the opening of the base frame 3.

In the present embodiment, the building B is exemplified by an apartment house such as a condominium. For example, the base frame 3 fixed to a building opening 2 such as a normal window or a sweep window with a mortar or the like. The sash frame 1 is attached via
In the embodiment, the base frame 3 is an old sash frame left as a base frame while being fixed to the building opening 2 in the past sash reform.
The current sash frame 1 is configured so that it can be replaced with a new one at a future sash reform.

As shown in FIG. 4, the base frame 3 includes a pair of vertical frame members 3 </ b> A and 3 </ b> B located on both side edges of the building opening 2, an upper frame member 3 </ b> C located on the upper edge of the building opening 2, and the building The lower frame member 3D located at the lower edge of the opening 2 is fixed to the building in a state of being integrated in a frame shape.
In the state before the past reforming, for example, protrusions 4 such as blindfolds, rails, windbreaks, rain dizziness, etc. on the opening inner peripheral surfaces of the respective frame members 3A, 3B, 3C, 3D extend along the longitudinal direction. However, some of the protrusions have been removed prior to the previous renovation, and both the vertical frame members 3A and 3B and the upper frame member 3C are at both ends in the depth direction of the building opening 2. The protrusion 4 is left only at the edge. Further, regarding the lower frame member 3D, only the rail is removed.
Therefore, the recessed grooves D sandwiched between the two protrusions 4 remaining on both side edges in the depth direction of the building opening 2 are formed on the inner peripheral surfaces of the openings of the vertical frame members 3A and 3B and the upper frame member 3C. Has been.
The sash frame 1 is installed in the recessed groove D.

The sash frame 1 is provided along a pair of vertical frame members 1A and 1B that are positioned along the inside of the opening of the pair of vertical frame members 3A and 3B of the base frame 3, and along the inside of the opening of the upper frame member 3C. An upper frame member 1C to be positioned and a lower frame member 1D to be positioned along the inside of the opening of the lower frame member 3D are provided. And each frame member 1A, 1B, 1C, 1D is being fixed to the said base frame 3 so that attachment or detachment is possible in the state which is not connected, respectively.

The base frame 3 is fixed. Specifically, as shown in FIG. 1, the elongated member 5 is disposed on the bottom surface portion 3Da of the lower frame member 3D of the base frame 3 with respect to the rising wall 3Db portion of the lower frame member 3D. It is fixed with a horizontal screw. In addition, the lower frame member 1D of the sash frame 1 disposed on the long member 5 is fixed to the long member 5 with a short vertical screw that does not reach the bottom surface portion 3Da.
Since the lower frame members 1D and 3D are installed in a portion where water is particularly easy to contact as compared with other frame members, there is a high risk of water leakage to the building frame through the screw holes. By adopting the fixing structure, it is not necessary to provide a screw hole in the bottom surface portion 3Da of the lower frame member 3D, and it is easy to prevent water leakage.
The long member 5 has a function of receiving and supporting a load acting on the lower frame member 1D in addition to the function of screwing.

The lower frame member 1D has a bottom surface 1Da formed in a stepped shape that descends from the indoor side to the outdoor side, and a pair of rails 6A along the longitudinal direction are spaced apart in the opening depth direction. It is integrally formed.
In addition, the length of the lower frame member 1 </ b> D is set to a dimension that covers almost the entire length of the opening width of the base frame 3. And about both ends, it is comprised in the structure without the said rail 6A so that the lower end part of the said vertical frame members 1A and 1B can be installed in a mounting state.

As shown in FIG. 2, the vertical frame members 1 </ b> A and 1 </ b> B are formed in a groove-shaped cross section, and the groove bottom surface portions 1 </ b> Aa and 1 </ b> Ba are individually positioned on the front and back sides of the edge portion of the sash door S. A pair of wind shields 6B are integrally formed with an interval in the opening depth direction.
The lengths of the vertical frame members 1A and 1B are set to a size obtained by subtracting the height of the lower frame member 1D from the opening height of the base frame 3. And about a lower end part, the end surface process is carried out in the shape which follows the step shape of the said lower frame member 1D. And when installing inside the base frame 3, in the state which provided the sealing rubber G for seam stop water on the bottom face part 1Da of the edge part of lower frame member 1D (refer FIG. 4), it is vertical on it. By installing the frame members 1A and 1B so that the lower end surfaces of the frame members are pressed against each other, it is possible to improve the water stoppage of the joint portion between them.

As shown in FIG. 1, the upper frame member 1 </ b> C is formed in a groove-shaped cross section, and a pair of rails 6 </ b> A along the longitudinal direction is spaced apart in the opening depth direction on the groove bottom surface portion 1 </ b> Ca. Each is integrally formed.
Further, the length of the upper frame member 1C is set to a value obtained by subtracting the width of each of the vertical frame members 1A and 1B1D from the opening width of the base frame 3. And as shown in FIG. 4, the notch K which swallows the windshield 6B is formed in both ends separately.

Next, a method for reforming the sash frame 1 will be described in order.
