Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention covers a gap between two building frames installed so as to form a corner portion orthogonally facing each other, such as a wall frame and a ceiling frame, a wall frame and a wall frame, and a wall frame and a floor frame. It relates to an expansion joint covered with a material.
[0002]
[Prior art and its problems]
In general, in an expansion joint, a support member is fixed to each of the building bodies facing each other with a gap therebetween, and a cover material for closing the gap is attached to this support member via a holder. Since the cover material is relatively displaced due to settlement, temperature change, and the like, the cover material must be changed correspondingly.
[0003]
However, the conventional holder has not always been able to reliably cope with the displacement of the building frame. In particular, a smooth response was insufficient for movements in which the building frames were separated from each other and approached.
[0004]
On the other hand, as an expansion joint for covering a gap between two building frames installed so as to form a corner portion orthogonally to each other with a cover material, conventionally, the above-mentioned cover material is always connected to the above-mentioned via a spring material. A device that urges in a direction to close the gap is known (for example, see Patent Document 1).

Japanese Patent No. 3063028 (full text, FIGS. 1 to 37)
[0006]
[Problems to be solved by the invention]
However, in a configuration in which the cover material is simply urged by the spring material, the cover material is limited to a range in which the spring material can expand and contract. Therefore, when the building frame is largely displaced, especially when the two building frames are separated from each other and the gap becomes large, the amount of displacement of the spring cannot keep up with this, and it may not be possible to cope well.
[0007]
An object of the present invention is to provide an expansion joint that can solve the above-mentioned problems and can reliably cope with a large displacement of a building frame.
[0008]
[Means for Solving the Problems]
In order to solve the above problem, an expansion joint according to the present invention is an expansion joint that covers a gap between two building bodies installed so as to form a corner portion orthogonally to each other with a cover material. In the building frame, a cover material covering the gap between the two frames is supported so as to be slidable toward and away from the other building frame, and the cover material is provided between the one building frame and the cover material. A pressing means for pressing the tip of the material so as to contact the other building body is provided.
[0009]
It is preferable that the pressing means is formed by connecting the crossed links in a pantograph shape so as to be extendable and contractible, and is urged by a spring in the extension direction.
[0010]
It is preferable to arrange a cushioning material between the tip of the cover material and the other building frame.
[0011]
It is preferable that one end of the pressing means in the expansion / contraction direction is attached to the cover material, and the other end is attached to the one building frame or a support member fixed to the building frame.
[0012]
Preferably, the pressing means is provided on the back side of the cover material.
[0013]
It is preferable that a rail receiver is fixed to the one building frame, and the cover member includes a slide rail slidable in the direction of approaching and separating from the other building frame along the rail holder.
[0014]
The rail receiver may be formed to have a dovetail cross section, the slide rail may be slidably engaged inside the rail receiver, and a bearing may be mounted between the slide rail and the rail receiver.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
1 is a plan view of the expansion joint, FIG. 2 is a side view thereof, FIG. 3 is a cross-sectional view taken along line XX of FIG. 1, and FIG. 4 is a cross-sectional view taken along line YY of FIG. In the figure, reference numeral 1 denotes a wall frame, and 2 denotes a ceiling frame. The wall skeleton 1 and the ceiling skeleton 2 are building skeletons that are installed so as to be orthogonal to each other with a gap S therebetween so as to form a corner portion. Note that the building frame may be a wall frame and a floor frame, a wall frame and a wall frame, a ceiling frame, a roof frame, or the like as long as the building frame is installed so as to form a corner portion.
[0016]
Between the wall frame 1 and the ceiling frame 2, a cover member 3 for closing the gap S is attached. The cover member 3 is formed by fixing a panel 6 made of metal or the like to a lower surface of a frame body in which a frame member 4 having a substantially U-shaped cross section (and a reinforcing member 5 having a U-shaped cross section) is assembled in a square shape. One cover member 3 is formed by combining the cover members 3a and 3b. Further, slide rails 8 project from inner vertical surfaces 7 of the frame members 4 on both sides of the cover members 3a and 3b that are perpendicular to the gap S.
[0017]
Note that a cushioning material 9 made of an elastic material such as rubber is attached to a tip of the cover member 3 on the side of the wall frame 1.
[0018]
Next, a hanging member 10 is suspended from a lower portion of the ceiling frame 2, and a support member 11 having an L-shaped cross section provided at a right angle to the gap S is fixed to a lower end of the hanging member 10. Two pairs of support members 11 are arranged corresponding to the slide rails 8 of the two large and small cover members 3a and 3b. The intermediate portions of the two pairs of support members 11 are connected via connection support members 11a corresponding to the respective cover members 3a and 3b.
[0019]
As shown in detail in FIGS. 4 and 5, a dovetail-shaped rail receiver 13 is fixed to a vertical surface inside each support member 11 along its longitudinal direction, and a slide rail 8 is provided inside the rail receiver 13. It is slidably engaged. Note that a bearing 14 is mounted between the rail receiver 13 and the slide rail 8.
[0020]
With the above configuration, the slide rail 8 is slidably provided on the rail receiver 13, whereby the cover member 3 is slidably supported in the approaching / separating direction with respect to the wall frame 1. The rail receiver 13 and the slide rail 8 are provided on the back side of the cover member 3.
[0021]
Next, pressing means 15 is provided between the wall frame 1 and the cover member 3 to press the front end of the cover member 3 so as to contact the other building frame.
[0022]
The pressing means 15 is formed by connecting the crossed links 16 in a pantograph-like manner so as to be expandable and contractible, and is disposed on the back side of the cover member 3. One end 15a of the pressing means 15 in the direction of expansion and contraction is attached to the frame member 4 on the tip end side of the cover member 3, and the other end 15b is attached to a connection support member 11a fixed to the ceiling frame 2. In addition, the said other end may be comprised so that it may attach to ceiling skeleton 2 via a suitable metal fitting. Further, the one end may be attached to the frame member 4 on the side opposite to the front end side of the cover member 3.
[0023]
The pressing means 15 has a shape in which three rhombuses are continuous, and a spring member 17 is mounted on a diagonal line of each rhombus portion, and the pressing means 15 is urged in the extension direction by the spring force of the spring material 17. Therefore, the front end cushioning material 9 of the cover material 3 is pressed so as to always contact the wall frame 1.
[0024]
In the above configuration, the cover member 3 is normally spring-biased in the extension direction, and the tip cushioning member 9 is pressed so as to always contact the wall frame 1. Thereby, the gap S between the wall frame 1 and the ceiling frame 2 is closed by the cover material 3.
[0025]
By the way, since the building frame is relatively displaced by vibration, uneven settlement, temperature change, etc., the ceiling frame 2 is relatively displaced in the vertical or horizontal direction with respect to the wall frame 1.
[0026]
The displacement in the vertical direction can be handled by the tip of the cover member 3 sliding along the wall surface of the wall frame 1.
[0027]
On the other hand, when displacing in the horizontal direction, the wall frame 1 and the ceiling frame 2 approach or separate from each other. When approaching each other, the tip of the pantograph-shaped pressing means 15 is pressed by the wall frame 1, the pressing means 15 is deformed and reduced as indicated by the dotted line in FIG. 6, and the spring material 17 is extended. When they are separated from each other, the wall body 1 is separated, so that the pressing means 15 is deformed and expanded as shown by the dotted line in the figure, and the spring material 17 is contracted. In any case, the slide rail 8 of the cover member 3 slides along the rail receiver 13 of the support member 11, and the front end of the cover member 3 is always in contact with the wall frame 1 by the pressing force of the pressing means 15. Even when the building frame is rapidly displaced and the tip of the cover member 3 strongly hits the wall frame 1, the shock absorbing member 9 is attached to the tip of the cover member 3, so that the impact is reduced and the cover is covered. The deformation of the material 3 can be favorably prevented.
[0028]
As described above, even when the wall frame 1 and the ceiling frame 2 are relatively displaced, the cover member 3 always closes the gap S between the two frames by the pressing means 15, but the pressing means 15 is particularly formed in a pantograph shape. Therefore, the range of variation at both ends is larger than the range of expansion and contraction of the spring member 17 itself. In other words, the pressing means 15 expands and contracts longer than the range of expansion and contraction of the spring member 17. can do.
[0029]
Further, since the cover member 3 is composed of two types of large and small cover members 3a and 3b, the two types of cover members 3a and 3b can be combined according to the size of the ceiling frame 2.
[0030]
Further, since a bearing is mounted between the slide rail 8 and the rail receiver 13, the slide is performed lightly and smoothly.
[0031]
Note that the pressing means 15 is not necessarily limited to the above-described structure. For example, as shown in FIG. 7, one diamond may be formed by the link 16.
[0032]
Further, the cover member 3 is not necessarily limited to the one configured by the two types of cover members 3a and 3b. For example, as shown in FIG. 8, a single cover material 3 may be used. Also in this case, the support member 11 and the cover member 3 may be provided with the rail receiver 13 and the slide rail 8 that can sufficiently support the weight of the cover member 3. The pressing means 15 may have a suitable configuration and may be arranged in only appropriate rows. The rail receiver 13 may be attached to the reinforcing member 5 provided in the width direction of the cover member 3 together with the support member 11.
[0033]
Also in the above configuration, the cover member 3 is spring-biased in the extension direction, and the tip cushioning member 9 is pressed so as to always contact the wall frame 1. Thereby, the gap S between the wall frame 1 and the ceiling frame 2 is closed by the cover material 3.
[0034]
By the way, since the building frame is relatively displaced by vibration, uneven settlement, temperature change, etc., the ceiling frame 2 is relatively displaced in the vertical or horizontal direction with respect to the wall frame 1.
[0035]
The displacement in the vertical direction can be handled by the tip of the cover member 3 sliding along the wall surface of the wall frame 1.
[0036]
On the other hand, when displacing in the horizontal direction, the wall frame 1 and the ceiling frame 2 approach or separate from each other. When approaching each other, the tip of the pantograph-shaped pressing means 15 is pressed by the wall frame 1, and the pressing means 15 is deformed and reduced in the same manner as shown in FIG. 6, and the spring material 17 is extended. When separated from each other, the wall body 1 is separated, so that the pressing means 15 is similarly deformed and expanded, and the spring member 17 is contracted. In any case, the slide rail 8 of the cover member 3 slides along the rail receiver 13 of the support member 11, and the front end of the cover member 3 is always in contact with the wall frame 1 by the pressing force of the pressing means 15. Even when the building frame is rapidly displaced and the tip of the cover member 3 strongly hits the wall frame 1, the shock absorbing member 9 is attached to the tip of the cover member 3, so that the impact is reduced and the cover is covered. The deformation of the material 3 can be favorably prevented.
[0037]
As described above, even when the wall frame 1 and the ceiling frame 2 are relatively displaced, the cover member 3 always closes the gap S between the two frames by the pressing means 15, but the pressing means 15 is particularly formed in a pantograph shape. Therefore, the range of expansion and contraction is larger than the range of expansion and contraction of the spring member 17 itself, that is, the pressing means 15 expands and contracts longer than the range of expansion and contraction of the spring member 17. be able to.
[0038]
In the above-described embodiment, the relationship in the case where the two building frames are the wall frame 1 and the ceiling frame 2 has been described. However, the two building frames which are installed so as to form a corner portion orthogonally to each other are described. If so, the relationship between the wall frame 1 and the floor frame, or the relationship between the wall frame 1 and the wall frame 1 may be used.
[0039]
【The invention's effect】
According to the first aspect of the present invention, even when the two building bodies approach or separate from each other, the cover member is always in contact with the other building body by the pressing means. Will be blocked.
[0040]
According to the second aspect of the present invention, the pressing means is configured to connect the crossed links in a pantograph shape so as to be expandable and contractable, and to urge the spring in the extending direction. The range is larger than the range of expansion and contraction of the spring material itself, that is, since the pressing means expands and contracts longer than the range of expansion and contraction of the spring material, it is possible to sufficiently cope with the displacement of the building frame.
[0041]
According to the invention according to claim 3, since the cushioning material is arranged between the tip of the cover material and the other building skeleton, the shock when the building skeleton fluctuates is reduced, and the cover material and the building skeleton are reduced. Deformation and breakage can be prevented.
[0042]
According to the invention according to claim 4, one end of the pressing means in the expansion and contraction direction is attached to the cover material, and the other end is attached to the one building frame or a support member fixed to the building frame. It can expand and contract efficiently.
[0043]
According to the fifth aspect of the present invention, since the pressing means is provided on the back side of the cover material, the pressing means is not visible.
[0044]
According to the invention of claim 6, when the two building frames approach or separate from each other, the tip of the pantograph-shaped pressing means is pressed by the wall frame, the pressing means is deformed, and the spring material expands and contracts. In either case, the slide rail of the cover material slides along the rail receiver, and the tip of the cover material is always in contact with the wall frame by the pressing force of the pressing means.
[0045]
According to the invention according to claim 7, the slide rail can slide lightly and smoothly with respect to the rail receiver, and the cover member can quickly move in response to the displacement of the building frame.
