Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a support structure for attaching a window frame to a wall member.

(Conventional Technology) In Japan, where earthquakes occur frequently, earthquake resistance technology for buildings is extremely advanced. As buildings become taller in recent years, more advanced technologies than ever have been developed or are being awaited.

Window frames that form part of a building are no exception. One of the technical issues regarding this window frame is the support structure technology for the window frame relative to the wall member. In other words, even if a building is distorted due to vibrations caused by an earthquake, the window frame should not be distorted, or the distortion of the window frame should be kept to a minimum to prevent damage to the window frame or window glass. This is a technique for how to attach a window frame to a wall member.

The drawings of FIGS. 7 and 8 show the support structure for the upper part of the conventional window frame, and this structure will be outlined below.

In the figure, reference numeral 10 is a window frame made of aluminum sash, and this window frame 10 is arranged in a rectangular hole 30 that is larger than the window frame 10 formed in the wall member 20. A window bracket 40 having an L-shaped cross-section is fixed to the upper part of the indoor side of the window frame 10, and a wall bracket 50 having an L-shaped cross-section is fixed to the indoor side of the wall member 20 located above the window frame 10. is fixed. Then, the horizontal portion 4 of the window bracket 40
0a and the horizontal portion 50a of the wall bracket 50 are arranged to face each other, and these horizontal portions 40a, 50
A sliding plate 61 is sandwiched between a.

Further, the horizontal portion 50a and the sliding plate 61 of the wall bracket 50 are provided with round holes, and the horizontal portion 40a of the window bracket 40 is provided with a long hole extending in the left-right direction in FIG. . Further, the bolt 71 (connecting tool) inserted from the wall bracket 50 side into the washer 82 and the above-mentioned round hole and elongated hole passes through another sliding plate 62 and washer 81 arranged on the window bracket 40 side. It is screwed into a nut 72 (coupling tool). The sliding plates 61 and 62 are made of a material with a small coefficient of friction, such as stainless steel or Teflon (trade name).

Further, the lower part of the window frame 10 is fixed to a lower wall member via a bracket.

When a building shakes sideways due to an earthquake,
A relative horizontal displacement occurs between the wall member 20 located above and the wall member located below the window frame 10.
At that time, the bolt 71 is attached to the window bracket 40.
The sliding plate 6 is inserted between the horizontal part 50a of the wall bracket 50 and the washer 81 and the horizontal part 40a of the window bracket 40.
1 and 62 are interposed, so the window bracket 4
0 moves horizontally relative to the wall bracket 50. As a result, the window frame 10 can theoretically move together with the lower wall member without being restrained by the upper wall member 20, and the distortion of the window frame 10 caused by the relative displacement of the upper and lower wall members 20 can be reduced. Prevented.

(Problems to be Solved by the Invention) However, in the conventional window frame support structure described above, although the friction coefficient of the sliding plates 61 and 62 is small, there is no surface contact with the horizontal portion 40a of the window bracket 40. Therefore, the frictional resistance is relatively large. or,
It is difficult to adjust the fastening force of the bolts 71 and nuts 72 at each support portion of the window frame 10, and there are support portions that are extremely difficult to slip.

As a result, there was a risk that the window frame 10 would actually be restrained by the upper wall member and deformed, leading to damage.

(Means for solving the problem) This invention was made to solve the above problem, and its gist is that wall brackets are installed on the wall members located above and below the window frame. is,
In a window frame support structure in which a window bracket provided on the window frame opposite to the wall bracket is supported by the wall bracket via a connector, at least one of the upper and lower wall brackets The window frame support structure is characterized in that a bearing is disposed between the window bracket and the window bracket facing the window frame.

(Function) Since the bearing is interposed between the wall bracket and the window bracket, the frictional resistance between them is extremely small, and the relative horizontal movement of the wall bracket and window bracket is performed very smoothly.
Furthermore, the fastening force of the connector has almost no effect on the frictional resistance.

Therefore, even if the wall members located above and below the window frame are displaced relative to each other due to an earthquake, the window frame can smoothly move horizontally relative to at least one of the upper and lower wall members. Deformation and damage to the window frame can be prevented by not receiving much horizontal force from the members.

(Example) Hereinafter, an example of this invention will be described based on the drawings from FIG. 1 to FIG. 6.

FIG. 5 shows a window frame 10 attached to a wall member 20.
6 is a schematic sectional view of the same. The window frame 10 has a frame 11 made of aluminum sash, and a window glass 12 is attached to the frame 11.

The window frame 10 is placed in a rectangular hole 30 that is larger than the window frame 10 formed in the wall member 20, and the window frame 10 is attached to the wall member 20a such as a slab board located above with three supports. 100, and is also supported by three supporting parts 101 on the lower wall member 20b.

The support part 100 at the upper part of the window frame 10 is constructed as shown in FIGS. 1 to 3.

A head portion of a bolt 91 is slidably inserted into a groove portion 11a formed on the indoor side of the frame 11 in the upper part of the window frame 10. Further, a window bracket 40 having an L-shaped cross section is arranged on the indoor side of the frame 11.
The vertical portion 40b of the bolt 91 and the washer 92,
It is fixed to the frame 11 with nuts 93.

Four protrusions 41 are formed in parallel on the upper and lower surfaces of the horizontal portion 40a of the window bracket 40, respectively. A long hole 42 is formed along the longitudinal direction of the projection 41 between the second and third projections 41 and 41 from the indoor side. Also, between the first and second protrusions 41, 41 from the indoor side, and between the third and fourth protrusions 41, 41
Support plates 43, 43 are slidably arranged between them, respectively, and long holes having an arcuate cross section are formed in these support plates 43 at predetermined intervals. A roller bearing 60 is housed in each of the long holes. Note that the roller bearing 60 is made of stainless steel, for example.

Further, on the indoor side of the wall member 20a, a wall bracket 50 having an L-shaped cross section has its vertical portion 50b connected to the wall member 2.
0a and is fixed by a bolt 94 and washer 95. The wall bracket 50 is arranged with its horizontal portion 50a facing the horizontal portion 40a of the window bracket 40, and the bottom surface of the horizontal portion 50a of the wall bracket 50 is connected to the roller bearing 6.
It is in contact with 0. In this horizontal part 50a, a long hole 51 for mounting adjustment is connected to a long hole 42 of the window bracket 40.
It is provided in a direction perpendicular to the

Furthermore, the horizontal portion 50a of the wall bracket 50
A stopper plate 73 and a washer 82 having a U-shaped cross section are arranged on the upper side. Stopper plate 7
A long hole 73b for mounting adjustment corresponding to the long hole 51 of the wall bracket 50 is provided in the horizontal portion 73a of No. 3, and two stopper claws 73c extend downward from both ends of the horizontal portion 73a. There is.
These stopper claws 73c are located between the first and second projections 41 and 41 from the indoor side provided on the upper surface of the horizontal portion 40a of the window bracket 40.
and is located between the third and fourth protrusions 41, 41.

Further, another stopper plate 74 similar to the stopper plate 73 and a washer 81 are arranged below the horizontal portion 40a of the window bracket 40.
However, the horizontal part 74 of this stopper plate 74
A is provided with a round hole 74b instead of a long hole. The horizontal portion 74a of the stopper plate 74 abuts against a roller bearing 60 disposed on the lower surface side of the horizontal portion 40a of the window bracket 40,
Each stopper claw 74c extends downward from both ends of 4a.
are positioned between the protrusions 41 provided on the lower surface of the horizontal portion 40a of the window bracket 40.

Then, the bolt 71 is inserted through the washer 82, the long hole 73b of the stopper plate 73, the long hole 51 of the wall bracket 50, the long hole 42 of the window bracket 40, the round hole 74b of the stopper plate 74, and the washer 81. , is screwed into the nut 72. In this embodiment, a bolt 71 and a nut 72 constitute a connector.

Note that sealing materials 81 and 82 are sandwiched between the frame 11 of the window frame 10 and the wall member 20a.

Further, the support portion 101 on the lower side of the window frame 10 has brackets 40, 50, bolts, and nuts, but does not have a bearing 60 or stopper plates 73, 74. In addition, in the central support part 101, the window bracket 40 has a round hole instead of a long hole, through which a bolt is inserted, and the lower wall member 20b
Movement of the window frame 10 is prohibited. Moreover, in the left and right support parts 101, window brackets 40
has a long hole and is designed to absorb thermal expansion of the window frame 10.

In the above configuration, the window frame 10 is connected to the lower wall member 2

It can be moved horizontally very smoothly.

That is, the bolt 71 moves integrally with the wall member 20a together with the wall bracket 50, both stopper plates 73 and 74, and the nut 72, but this bolt 71 is horizontally movable within the elongated hole 42 of the window bracket 40. Therefore, the window frame 10 can move horizontally relative to the wall member 20a.

In particular, the horizontal portion 40a of the window bracket 40,
Since the roller bearing 60 is arranged between the horizontal part 50a of the wall bracket 50 and the stopper plate 74 and is in rolling contact, the frictional resistance between them is extremely small (μ=
0.11 to 0.025), the window bracket 40 can be smoothly moved relative to the wall bracket 50. Further, in each support part 100, the bolt 7
1. Even if there is a difference in the fastening force of the nut 72,
Since the effect on frictional resistance is very small, the ease of movement in each support portion 100 does not change.

Therefore, due to the earthquake, the wall members 20a, 20b
is relatively displaced, the window frame 10 is not restrained by the upper wall member 20a and is moved to the lower wall member 20b.
Since the window frame 10 can be moved smoothly by following the movement of the window frame 10, the window frame 10 is not deformed or is only slightly deformed, and the window frame 10 and the window glass 12 are not damaged. . As a result, even if an earthquake occurs, the waterproofness of the window frame 10 will not deteriorate.

Note that FIG. 4 shows a front view of the support portion 100 when the window frame 10 is horizontally moved relative to the wall member 20a. At this time, each stopper plate 7
The stopper claws 73c and 74c of 3 and 74 hook one end of the support plate 43 disposed on the upper and lower surfaces of the horizontal portion 40a of the window bracket 40, and prevent the support plate 43 and the roller bearing 60 from popping out. .

This invention is not limited to the above-mentioned embodiments, and various embodiments are possible. For example, the bearing may be a ball bearing. Further, this invention may be applied to the support portion between the lower wall member and the window frame, or to the support portion between both the upper and lower wall members and the window frame. Furthermore, it can also be applied to support window frames that have windows that can be opened and closed; in this case, damage to the opening/closing mechanism provided in the window frame is prevented, and the opening and closing of windows can be ensured even in the event of an earthquake. It's safe.
