Description

The present invention relates to a building joinery in which a joinery frame is attached to an opening of a building wall .

As joinery, it is common to attach construction details such as doors and shoji to the joinery frame.
On the other hand, as a building wall, a wooden building wall using a wood-based material and a non-wooden building wall using a concrete-based material such as an RC, a PC plate, or an ALC plate are known.
In the case of the wooden building wall, nails can be driven into the building wall. Therefore, it is common to mount the fitting frame by nailing.
In the case of the non-wooden building wall, since it is impossible to drive nails into the building wall, it is common to attach the joinery frame other than by nailing.
For this reason, there are problems such as high cost because the joinery frame requires two types, one for wooden construction that is attached by nailing and the other for non-timber construction that is attached by other than nailing.

In order to solve this problem, various joinery frames that can be attached to both a wooden building wall and a non-wooden building wall have been proposed.
For example, as disclosed in Patent Document 1, an auxiliary frame is attached to the inner peripheral surface of the opening of a non-wooden building wall, and a wooden joinery frame is attached to the auxiliary frame.

The upper frame 30, the lower frame 31, and the left and right vertical frames 32 are framed, the attachment pieces are removed, and the joinery frame 3 to which the anchors are respectively attached is formed.
That is, the attachment piece may be removed before or after the frame, and the anchor may be attached before or after the frame.

A step of inserting the joinery frame 3 into the opening 2 and providing it in the opening 2.
Connecting the joinery frame 3 and the building wall 1 by welding the weld bars 7 to the welded parts 6 and the anchors.
A step of providing a sealing material between the outdoor portion of the joinery frame 3 and the inner peripheral surface of the opening 2 of the building wall 1.

As such, by connecting the building wall 1 and the joinery frame 3 provided in the opening 2 thereof directly by the connecting means 4 and removing the attachment pieces of the joinery frame 3, the joinery frame 3 is removed. The wooden frame 3 can be attached to the opening 2 of the non-wooden building wall 1 without enlarging the opening 2 of the building wall 1.
Moreover, since it is only necessary to provide a sealing material between the inner peripheral surface of the opening 2 and the outdoor portion of the outer peripheral surface of the fitting frame 3, the sealing work is simple.
In addition, since the attachment piece is removed, the joiner frame 3 to which the anchor is attached is inserted into the opening 2 and the welding bar 7 is welded to the anchor and the welded portion 6, the joinery frame 3 is opened to the opening of the building wall 1. The work of attaching to the part 2 is simple.

Since the connecting means 4 is composed of an anchor, a welded part 6 and a welding bar 7, since the structure is simple and the cost is low, the building joinery can be made inexpensive.
Further, since the anchor is fixed to the joinery frame 3 with screws, the anchor can be attached to the joinery frame 3 made of aluminum and welded to the opening 2 as described above.

As shown in FIG. 2, the upper inner surface 2a of the opening 2 has a step so that the indoor portion is positioned higher than the outdoor portion, and the welded portion 6 is exposed to the indoor portion. It is.
Since it is like this, since the vertical dimension between the outer surface 30a of the upper frame 30 and the indoor side part of the upper inner surface 2a is larger than the vertical dimension between the outdoor part and the outer surface 30a of the upper frame 30, The work of welding the welded portion 6 and the weld bar 7 from the inside can be easily performed, and the sealing width can be reduced by reducing the seal width by the upper sealing material 10.

The welded part 6 is a reinforcing bar called a reinforcing bar as shown in FIGS. 2 and 3 and is embedded in the building wall 1 so that a part thereof is exposed on the inner surface.
For example, one side portion 6a that faces in the out-of-plane direction (prospective direction), the other side portion 6b, and an intermediate portion 6c that goes in the in-plane direction (finding direction) have a substantially crank shape, and the one side portion 6a is formed on each of the inner surfaces 2a and 2b. , 2c are embedded so as to be exposed in the inwardly recessed portion 2d.
Since it is like this, the welding reinforcement 7 can be welded to the to-be-welded part 6 in the inward recessed part 2d, and the welding part can be prevented from projecting from the inner surface, so the dimension between the inner surface and the outer surface of the joinery frame 3 can be reduced. It can be made smaller.

As shown in FIGS. 4 and 5, the upper anchor 5 has an attachment portion 5 a and a weld portion 5 b, and the attachment portion 5 a is in contact with the outer surface 30 a of the upper frame 30 and is fixed by screws 50.
The screw 50 is prevented from projecting to the inner surface 30b of the upper frame 30.
For example, as shown in FIG. 2, the portion of the upper frame 30 to which the screw 50 is screwed is formed into a shape having a double wall and a hollow portion, and the screw 50 protrudes into the hollow portion.

The welding part 7 is in contact with the surface (vertical surface) facing the up-down direction of the welded part 5b for welding.
The vertical dimension of the welded part 5b is larger than the vertical dimension of the mounting part 5a, and the contact length in the vertical direction between the welded part 5b and the weld bar 7 can be increased without increasing the vertical dimension of the entire upper anchor 5. is there.
For example, both side edges of the plate-like base piece 51 are bent upward to form a bent piece 52, the bent piece 52 is used as a welded portion 5b, and a hole 53 is formed in the base piece 51 as the attaching portion 5a. is there.
In FIG. 4, the hatched portion (all) of the upper mounting piece 33 is removed, and the outer surface 30a of the upper frame 30 is a flat surface without the upper mounting piece 33 as shown in FIG.

As shown in FIGS. 6 and 7, the lower anchor 8 has an indoor-side mounting portion 8a and an outdoor-side mounting portion 8b that are separated from each other in the out-of-plane direction, and an out-of-plane direction between the indoor-side mounting portion 8a and the outdoor-side mounting portion 8b. An intermediate welded portion 8c is provided, and the indoor side attached portion 8a and the outdoor side attached portion 8b are separated from each other in the out-of-plane direction of the lower frame 31 by screws 81. Each is fixed and attached.
In this embodiment, a part of the hatched portion of the lower mounting piece 34 is removed, and the remaining portion 34a of the lower mounting piece 34 is used as an outdoor mounted portion 31c to which the outdoor mounting portion 8b of the lower anchor 8 is attached.
The outdoor mounting portion 8b of the lower anchor 8 is in contact with the outdoor mounting portion 31c via a spacer 82 made of a heat insulating material, and is fixedly attached with a screw 81.

As shown in FIG. 2, the weld bar 7 is welded with its upper part in the longitudinal direction coming into contact with the vertical surface of the welded portion 8c in the vertical direction.
Since the welded portion 8c is separated from a portion of the lower frame 31 between the indoor-side mounted portion 31b and the outdoor-side mounted portion 31c, the welding bar 7 is connected to the welded portion 8c as shown in FIG. The vertical surface can be welded so as to protrude above the vertical surface, and the vertical length of the welding can be increased.

The lower anchor 8 is formed, for example, by bending a plate-like substrate 83 into a substantially crank shape, forming a hole 84 in the upper portion thereof to form the indoor mounting portion 8a, and forming a hole 84 also in the lower portion. The outdoor mounting portion 8b is provided.
The edge of the intermediate portion of the substrate 83 is bent into a bent piece 85, and the bent piece 85 is used as a welded portion 8c.

As described above, the lower anchor 8 is fixed to the lower frame 31 at two locations separated in the out-of-plane direction, and the welding bar 7 is welded in the middle of the two fixing portions in the out-of-plane direction. 7, the lower frame 31 can be firmly supported and attached to the lower inner surface 2 b of the opening 2 of the building wall 1.
That is, since the weight of the fitting is loaded on the attachment portion of the lower frame 31, it is desirable to attach and support it firmly.

As shown in FIGS. 8 and 9, the vertical anchor 9 has an attachment portion 9a and a welded portion 9b. The attachment portion 9a is fixedly attached to the vertical frame 32 with a screw 91 and welded to the welded portion 9b. 7 is welded as shown in FIG.

The attachment portion 9a is in contact with the remaining portion 35a and is fixed by a screw 91. The screw 91 is attached to the vertical frame 32. The inner surface 32b is not projected.

In this embodiment, as shown in FIGS. 4 and 8, the upper anchor 5 and the vertical anchor 9 are the same.
For example, a vertical piece 92 is integrally provided at the end of the attachment portion 5a (substrate 51) of the upper anchor 5, and a hole 93 is formed in the vertical piece 92 to form the attachment portion 9a of the vertical anchor 9. The welded part 5b (the bent piece 52) of 5 is used as the welded part 9b of the vertical anchor 9.

The welding bar 7 is a steel bar having a circular cross section that is bent into a substantially U shape.
Since it is like this, the space | interval of the welding part and each to-be-welded part 6 with each anchor can be made small. That is, if the weld bar 7 is in a straight line shape, the distance between the welded portion of the anchor and the welded portion 6 is increased. Therefore, the space | interval of the inner peripheral surface of the opening part 2 and the outer peripheral surface of the fitting frame 3 can be made small.
In addition, since the area which contacts the welding part of the anchor and the to-be-welded part 6 can be enlarged if the welding rod 7 is made into polygonal cross-sectional shape, it can weld firmly.

  After attaching the joinery frame 3 to the opening 2 of the building wall 1 as described above, the connecting means 4 is filled with mortar 13 between the inner peripheral surface of the opening 2 and the outer peripheral surface of the joinery frame 3. It is supposed to be buried.
