Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a body joint device (expansion joint) that connects adjacent bodies via a body gap and can follow the body fluctuation caused by an earthquake or the like to absorb this body fluctuation, and in particular, a single cover. The present invention relates to a single-piece frame joint device for closing a frame gap with a material.
[0002]
[Prior art and problems to be solved by the invention]
In this type of frame joint device, that is, a single-layer type frame joint device that covers the frame gap with a single cover material, conventionally, both sides of the cover material that are movably fixed via a spring material or the like. There are two types, a fixed type and a one-side fixed type in which one of the cover materials is fixed movably with a spring material and the other is free.
[0003]
As shown in FIG. 19, for example, in the case of a body joint device that closes the gap S between the housings Q and R in which the wall surfaces are substantially flush with each other, as shown in FIG. A holder material 101 having a long hole 101a that is long in the hand direction (the direction in which the housing faces) is disposed across the housing gap S and projects into the housing gap S from the wall surfaces Q1 and R1 on both sides. A bolt 104 with a coil spring 103 is attached to the bolt support members 102 and 102 so as to be extendable in the depth direction of the housing gap, and the bolt head 104a of the bolt 104 is slidably inserted into the elongated hole 101a of the holder material 101. When the housings Q and R change in the short direction of the housing gap, the bolts 104 and 104 slide in the long hole 101a to absorb the housing variation. Skeleton fitting device 100 comprising configured so as to absorb the precursor varies depending expansion bolts 104 accompanied by expansion and contraction of the coil spring 103 and 103 has been known.
[0004]
Further, as shown in FIG. 20, in the case joint apparatus for closing the case gap V between the cases T and U formed by intersecting the wall surfaces T1 and U1 from the wall surface side, the length is long in the short direction of the case gap. A holder material 111 having a hole 111a and a non-long bolt insertion hole 111b provided on the bottom surface is disposed so as to straddle the gap V of the casing, and a coil spring is applied to the bolt support member 112 protruding from the wall surface T1 of the casing T into the casing gap V. A bolt 114 with 113 is mounted so as to be extendable in the depth direction of the housing gap, and the bolt head 114a of this bolt 114 is slidably inserted into the elongated hole 111a of the holder material 111, while the housing U is opened from the wall surface U1 of the housing U. A bolt 116 is attached to a bolt support member 115 projecting into the gap V, and a bolt head 116a of this bolt 116 is inserted into the insertion hole 111b of the holder material 111 between the housings. When it is inserted and engaged so as to be stretchable in the depth direction, and the case fluctuates in the short direction of the case gap, the bolt 114 slides in the long hole 111a to absorb the change in the case, and when the case fluctuates in the depth direction of the case gap, There has been known a frame joint device 110 configured to absorb the variation of the frame by expansion and contraction of the bolt 114 accompanied by expansion and contraction of 113.
[0005]
In any of these frame joint devices 100 and 110, the longer width of the long gap provided in the bottom surface of the holder material can be increased to increase the follow-up width with respect to the variation in the width direction of the frame gap. However, in this case, in order to increase the fluctuation following width in directions away from each other, the holder material must be enlarged and the width of the holder material stacked on the wall surface of the housing must be increased. This is not only inefficient in terms of cost, but also deteriorates the design, and further causes the problem that the support portion that supports the holder material must be strengthened in response to the increase in size of the holder material.
Further, in order to increase the following width in the frame gap depth direction, it is necessary to increase the length of the bolts 104 and 116. However, the frame joint devices 100 and 110 have the bolts 104 and 116 in the frame gaps S and V, respectively. Therefore, the thickness of the wall of the housing must be sufficiently larger than the length of the bolts 104 and 116. That is, the following width in this direction cannot be increased in any environment, and the spring strength of the coil springs 103 and 114 has a problem that the spring strength tends to decrease with time.
[0006]
On the other hand, as shown in FIG. 21, as the one-side-fixed type housing joint device, the base end side portion of the holder material 121 arranged so as to straddle the housing gap S can be rotated with respect to one housing Q. The housing joint device 120 having a configuration in which the front end side is in contact with the housing wall surface R1 in a free state is known.
[0007]
The frame joint device 120 can be freely changed in both the width direction of the frame gap and the lengthwise direction of the frame gap by making the front end side of the holder material 121 free. Moreover, since it can follow by rotation of the holder material 121 with respect to the depth direction of a housing gap, even if a housing changes to which direction, it can follow corresponding to this.
However, in order that the frame joint device 120 can follow a large variation in the width direction of the frame gap, the holder material 121 and the cover material 124 must be made larger and the width overlapping the wall surface R1 must be increased. As in the case of the above-described housing joint devices 100 and 110, problems arise in efficiency, design, and strength.
[0008]
Therefore, in order to solve such a conventional problem, the present invention can increase the following width in the lateral direction of the gap between the casings, in particular, the following width in the separation direction, and yet does not need to increase the size of the apparatus itself. It is intended to provide a frame joint device.
[0009]
[Means for Solving the Problems]
In order to solve such a problem, the present invention provides a single-piece frame joint device for connecting adjacent frames via a frame gap, a holder material disposed across the frame gap, and the holder material A slide material that is slidably disposed, a holder material stopper that urges the holder material in a restoring direction while rotatably attaching the proximal end side of the holder material to one housing, and a proximal end side of the slide material A one-piece frame joint device comprising: a slide material stopper that rotatably attaches to the other housing and urges the slide material in a restoring direction; and a cover material that covers the holder material and covers the housing gap. It was decided to compose.
[0010]
In the frame joint device having such a configuration, since one end of the holder material is free and the slide material is slidably disposed in the holder material, the adjacent frames vary in the short direction of the gap between the frames. In such a case, the change in the housing can be absorbed by the sliding of the slide material. In addition, the follow width at that time can follow the separation direction as long as the holder material and the slide material are superposed, and conversely, the tip of the holder material or the slide material is the housing in the proximity direction. It is possible to follow until it stops touching.
In addition, since the base end side of the holder material and the slide material are each rotatably attached to one housing and biased in the restoring direction, it is assumed that the housing repeatedly fluctuates so as to deviate from each other in the housing gap depth direction. However, it is possible to absorb this following the body fluctuation.
Moreover, in the normal state, the housing joint device of the present invention accommodates large housing fluctuations without increasing the size of the device itself because the slide material is accommodated in the holder material. It is also excellent in strength.
Furthermore, since the base end sides of the holder material and the slide material are fixed to the housing, even when a plurality of housing joint devices are arranged in parallel, it is possible to provide consistency to the operation of each housing joint device. The adjacent housing joint device does not collide and break.
[0011]
In the above configuration, the “holder material stopper” and the “slide material stopper” An elastic member is rotatably connected to the frame fixing plate via the shaft portion and the bearing portion. Can be configured. If it is such a structure, an elastic member can be axially fixed with respect to a housing, and a holder material or a slide material can be stopped rotatably via this elastic member.
[0012]
In that case, The length of the shaft part of the elastic member Holder material stopper and Slide material stopper By forming the elastic member longer than the length of at least one of the bearing portions and making the elastic member movable in the axial direction, it is possible to follow the fluctuation of the casing in the longitudinal direction of the casing gap.
[0013]
In addition, it is preferable to use an elastic member having a configuration in which two torsion springs are connected by a linear member. Although the elastic member is not limited to a spring having such a structure, since it has two torsion springs, the spring strength is higher than that of a torsion spring with one torsion spring or a coil spring. It is difficult to weaken, and it can also contribute to the follow-up operation in the longitudinal direction of the housing gap by the deformation of the linear member.
[0014]
In the configuration of the holder material stopper and the slide material stopper described above, the means for allowing rotation is not limited to such a configuration, and the holder material or the slide material may be fixed with the pin as an axis. It is also possible to configure.
[0015]
On the other hand, the holder material stopper and the slide material stopper At least one of Is Rod A slide receiving portion disposed along the longitudinal direction of the housing gap, a slide body that is slidably disposed in the slide receiving portion and includes an elastic member locking portion, and an elastic member may be used. If comprised in this way, a holder material or a slide material can be largely slidable to a housing gap | interval longitudinal direction. With respect to the case fluctuation in the longitudinal direction of the case gap, when the case joint apparatus is installed between the wall surfaces, this direction becomes the vertical direction. Even if a large earthquake is assumed, the fluctuation range is slight. However, when the frame joint device is disposed between the ceiling surfaces of the building, it is necessary to assume a large fluctuation range because this direction is a direction extending horizontally. Therefore, the configuration in which the holder material or the slide material can be largely slid in the longitudinal direction of the housing gap as described above is particularly effective as the configuration of the roof-type housing joint device disposed between the roofs of the buildings.
[0016]
In addition, as the above-mentioned “holder material”, for example, the other side of the cover material contact surface is formed in an approximately U-shaped cross section, and the U-shaped slide fits along the longitudinal direction. It can comprise so that a part may be provided. On the other hand, as the “slide material”, a wall portion is continuously provided in the longitudinal direction of the slide material body, and an elastic member is engaged with the wall portion. Elastic member locking part It can comprise so that it may provide.
[0017]
In the present invention, the “body gap short direction” means the direction in which the chassis faces, and the “frame gap depth direction” means the depth of the chassis gap when the cover material of the chassis joint device is viewed from the front. It means the direction to go back and forth. The “frame gap longitudinal direction” means a direction along the edge of the frame gap in which the frame joint device is disposed, in other words, a direction orthogonal to both the width direction of the frame gap and the depth direction of the frame gap.
[0018]

Are bent to form linear shaft portions 15d and 15d, and end portions of these shaft portions 15d and 15d are bent to form retaining portions 15e and 15e. If the torsion spring has two torsion springs 15a, the spring strength is high and the spring force can be exerted without losing large housing fluctuations.
[0025]
As shown in FIG. 6, the elastic member 15 has shaft portions 15 d and 15 d inserted into bearing portions 13 and 13 of the housing fixing plate 14, while a latching arm portion 15 b is engaged with the holder material 2. 7A and 7B, the base end side of the holder material 2 is fixed to the housing A so as to be rotatable. At this time, when the tip end side of the holder member 2 is rotated in the direction of opening outward, as shown in FIG. 7A, for example, as shown in FIG. 7A, the torsion springs 15a and 15a are repelled. A force is applied to bias the holder material 2 in a restoring direction.
[0026]
As shown in FIGS. 4 and 5, the slide member 3 includes a long rectangular plate-like slide member body 3 a that can be slidably fitted into the slide fitting portion 7 of the holder member 2, and the slide member.

The length of the slide material 3 is not particularly limited, but about half of the holder material 2, in other words, about half of the short width of the case gap C, the change of the case in the short direction of the case gap in both directions. Can be absorbed in a well-balanced manner, and sufficient strength can be secured.
[0027]
The slide material 3 is slidably fitted into the slide fitting portion 7 of the holder material 2 (slidably inserted from the end of the holder material 2), and the slide material stopper 5 is attached. The base end side is rotatably attached to the housing B.
[0028]
Here, as shown in FIG. 3, the slide member stopper 5 includes a housing fixing plate 20 having a bearing 19 and an elastic member 21.
[0029]
The frame fixing plate 20 is provided with cylindrical bearings 22 and 22 at both ends along one side edge of the rectangular plate 20a, and a fixing member 23 such as a bolt is driven into the plate 20a to the wall surface B1. Overlaid and fixed.
[0030]
The elastic member 21 is a double torsion spring formed by bending a metal wire, and includes two coiled torsion springs 21a and 21a extending from the inner ends of the torsion springs 21a and 21a. The wire members are connected in a V shape to form the latching arm portion 21b, and the fixed arm portions 21c and 21c are extended from the outer end portions of the torsion springs 21a and 21a, and the ends of the fixed arm portions 21c and 21c are extended. The portions are bent to form linear shaft portions 21d and 21d, and the ends of the shaft portions 21d and 21d are further bent to form retaining portions 21e and 21e.
[0031]
The shaft portions 21d and 21d of the elastic member 21 are inserted into the bearing portions 22 and 22 of the housing fixing plate 20, while the latching arm portion 21b is engaged with the engagement groove portion 17 of the slide member 3 to slide the slide member. 3 is attached to the housing B so as to be rotatable. At this time, when the slide member 3 is rotatably attached via the elastic member 21, for example, when the tip end side of the slide member 3 is rotated in the opening direction, the repulsive force of the torsion springs 21a and 21a acts. The slide member 3 is urged in a restoring direction.
[0032]
In addition, in the slide material stopper 5, as shown in FIG. 19 The length of is more appropriately than the length of the shaft portion 21d of the elastic member 21. Short Formed (2h in the figure) Just shorter It is formed. ), Shaft portion 21d The It is movable in the axial direction.
[0033]
The cover material 6 hangs down along both lateral edges of the covering surface portion 6a having a short width longer than the short width of the housing gap C and a long width long along the gap C. 6b and 6b are formed, and a gasket 25.25 made of an elastic member such as rubber is attached to the lower side of the lower edge of the side surfaces 6b and 6b.
The cover material 6 is fixed by overlapping the covering surface portion 6a on the cover material contact surface 2a and driving a fixing member such as a bolt into the overlapping portion.
[0034]
Next, the operation of the housing joint device 1 will be described.
[0035]
As shown in FIGS. 9B and 9C, when the casings A and B change in the shorter direction of the gap between the casings, the slide member 3 slides in the holder member 2 to absorb the change in the casing. it can.
At this time, as shown in FIG. 9B, when the casings A and B change in the direction in which they approach each other, it is possible to follow until the tip of the wall portion 3b of the slide member 3 comes into contact with the casing A. Therefore, the following width in this direction can be further increased by cutting out the tip of the wall 3b (the hatched portion in the figure) of the slide member 3.
On the other hand, as shown in FIG. 9C, when the casings A and B fluctuate in a direction away from each other, the holder material 2 and the slide material 3 are superposed even if the slide material 3 is pulled out from the holder material 2. As long as the slide material main body 3a of the slide material 3 is fitted in the slide fitting portion 7 of the holder material 2, as long as the slide material main body 3a is fitted, it is possible to follow the housing fluctuation. That is, the maximum follow-up is possible by the length of the slide member 3. However, if the length of the slide member 3 is made too long, the following width when the casings A and B change in the proximity direction becomes narrow. Therefore, the length of the slide member 3 is preferably set to the length of the holder member 2 or It is set to be about half of the short width of the housing gap so that about half of the housing gap can be absorbed in any direction. In that case, the following width can be further expanded by cutting the tip of the wall 3a of the slide member 3 as described above.
[0036]
As shown in FIGS. 10 (A) and 10 (B), when the housings A and B change in the housing gap depth direction, both the holder material 2 and the slide material 3 are on the base end side via the elastic members 15 or 21. Is fixed to the housings A and B so that the housings A and B can be moved so as to protrude outwards without any limitation. can do. Moreover, since both the holder material 2 and the slide material 3 are urged in the restoring direction via the elastic members 15 or 21, the cases A and B always follow even if they repeatedly fluctuate in the depth direction of the case gap. Can vary.
[0037]
Although not shown in the figure, when the casings A and B change in the length of the gap between the casings (vertical direction in this example), the shaft portion 21d of the elastic member 21 in the bearing portion 22 in the slide member stopper 5 is provided. Is movable in the vertical direction, and the fixed arm portions 21c, 21c of the elastic member 21 are deformed to absorb the variation in the casing in this direction. Even in the case of a large earthquake, the vertical fluctuation range of the frame is small compared to the horizontal fluctuation range, and it is sufficient to be able to follow this extent.
Further, in the case of this embodiment, the housing B side can be changed in the bearing housing gap direction by the movement of the shaft portion in the bearing portion, while the housing A side is provided with the locking walls 14b and 14b so as to sandwich the holder material 2 therebetween. And since it is comprised so that it may not change to this direction, the tracking operation | movement of this direction between the adjacent frame connection apparatuses 1 and 1 can be given consistency, and it does not collide with each other.

A slide fitting portion 37 having a U-shaped cross section facing the opening edge is provided so as to interpose the portion 39. The holder member 32 is not provided with the engaging groove 8 unlike the holder member 2.
[0040]
As described above, the holder material 32 is disposed so as to straddle between the wall surfaces D1 and E1 across the housing gap F, and only the base end side is fixed to the housing by the holder material stopper 34, and the distal end side is the housing. On the other hand, it is in a free state without stopping.
[0041]
Here, as shown in FIGS. 12 to 15, the holder material stopper 34 includes a holder material mounting plate 43, a housing fixing plate 44, and an elastic member 45.
[0042]
As shown in FIG. 15, the holder material mounting plate 43 is cylindrical at both ends along one side edge (lower side edge in the figure) of the rectangular plate 43 a that matches the end opening of the holder material 32. Bearing portions 43b, 43b are provided, and one side edge in a direction intersecting with the plate bodies 43b, 43b is bent vertically and fitted into the space portion 39 and the slide fitting portion 37 in the holder material 32, respectively. Protruding pieces 43c, 43c provided with possible pieces are formed, and these protruding pieces 43c, 43c are inserted from the opening on the side of the housing D of the holder material 32, and bolts or the like are formed on the side surface of the holder material 32. A fixing member 46 is driven and fixed to the holder material 32.
[0043]
Further, as shown in FIG. 14, the housing fixing plate 44 is provided with cylindrical bearing portions 44b and 44b at both ends along one side edge of the rectangular plate portion 44a, and in the plate portion 44a, Locking walls 44c and 44c are erected at an interval at which the holder material 32 can be sandwiched, and the housing fixing plate 44 is piled on the wall surface D1 by driving a fixing member 46 such as a bolt into the plate body portion 44a. It is fixed.
[0044]
Further, the elastic member 45 is a double torsion spring similar to the elastic member 15, and as shown in FIG. 14, two coiled torsion springs 45a and 45a, a rectangular hooking arm portion 45b, and a fixed arm portion. 45c, 45c, shaft portions 45d, 45d, and retaining portions 45e, 45e, each torsion spring 45a is positioned outside the locking wall 44c of the housing fixing plate 44, and the shaft portions 45d, 45d are mounted on the housing fixing plate 44. The elastic member 45 is inserted into the bearing portions 44b and 44b so as to be pivotally supported with respect to the housing D, and the bearing portion 43a of the holder material mounting plate 43 having the latching arm portion 45b fixed to the holder material 32. 43a, the holder member 32 has its base end side rotatable relative to the housing D, and is restored when the holder member 32 is rotated by the repulsive force of the torsion springs 45a and 45a. It is biased to give a force in the direction.
[0045]
The slide material 33 and the slide material stopper 35 are configured in the same manner as the slide material 3 and the slide material stopper 5 described above.
[0046]
The cover material 36 is formed by forming a cross-covered surface portion 36b that covers the holder material stopper 34 by vertically bending one end in the short direction of the cover-surface portion 36a that covers the housing gap F. Both side edges in the short direction of the covering surface portion 36b are suspended to form side surface portions 36c, 36c, and gaskets 25, 25 made of an elastic member such as rubber are provided along the lower edge portions of the side surface portions 36c, 36c. The covering surface portion 36a is overlapped on the cover material abutting surface 32a and fixed by driving a fixing member such as a bolt into the overlapping portion.
[0047]
Similarly to the above-described frame joint device 1, the frame joint device 31 also has a structure in which the slide material 33 slides in the holder material 32 (protrusions are possible) when the frames D and E change in the width direction of the frame gap. Variations can be absorbed and the width of follow in this direction can be increased as well.
Further, even when the housings D and E change in the depth direction of the housing gap, even if any of the housings D and E changes so as to protrude outward, as with the housing joint device 1, the body D and E follow this without any limitation. Further, since both the holder material 32 and the slide material 33 are urged so as to be restored when they are rotated, it is assumed that the housings D and E have complicated and repeated fluctuations in the housing gap depth direction. However, it is always possible to follow this and to absorb this variation in the body.
Furthermore, even when the housings D and E change in the longitudinal direction of the housing gap (in the vertical direction in this example), as in the case of the housing joint device 1, the bearing portion of the slide member stopper 35 and the shaft portion of the elastic member The movement of the housing in this direction can be absorbed by the movement and deformation of the elastic member.

That is, this frame joint device 51 is configured in the same manner as the above-described frame joint device 1 with respect to the holder material 52, the slide material 53, the holder material stopper 54 (not shown), and the cover material 56, and these are constituted by the wall surface A1 and Instead of being attached to B1, it is similarly attached to the ceiling surfaces A2 and B2. On the other hand, the frame joint device 1 comprises the frame fixing plate 20 and the elastic member 21 to constitute the slide material stopper 5 and fixed to the frame B. The slide member 3 is pivotally attached to the housing B via the elastic member 21 by pivoting the elastic member 21 on the plate 20, whereas the housing joint device 51 includes a housing B as shown in FIG. The slide receiving portion 5 is arranged from the slide receiving portion 61 arranged along the gap edge of the housing, the slide body 62 slidably arranged in the slide receiving portion 61, and the elastic member 63. The elastic member 63 is engaged with the slide body 62 slidably disposed in the slide receiving portion 61 so that the slide member 53 can be slid in the longitudinal direction of the housing gap via the elastic member 63. It is installed.
[0050]
Here, the slide receiving portion 61 is formed by providing a slide rail portion 61b having a U-shaped cross section along one side edge of the fixing surface portion 61a that is fixed to the ceiling surface B2 of the casing B, and is fixed to the fixing surface portion 61a. A fixing member such as a bolt is driven in to fix the fixing surface portion 61a on the ceiling surface B2, and the slide rail portion 61b is arranged so as to project into the gap along the frame gap edge of the frame B.
[0051]
The slide body 62 is provided with a fixed collar portion 62b erected along the longitudinal direction at the center of one side surface of a long rectangular slide plate body portion 62a that can be fitted into the slide rail portion 61b of the slide receiving portion 61. In addition, elastic member locking holes 62c and 62c are provided at both ends of the fixed hook portion 62b. The slide body 62 has a slide plate body portion 62a in the slide rail portion 61b of the slide receiving portion 61. It is slidably inserted.
[0052]
The elastic member 63 is a double torsion spring formed by bending a metal wire, and includes two coiled torsion springs 63a and 63a, which extend from the inner ends of the torsion springs 63a and 63a. The wire members are connected in a V shape to form the latching arm portion 63b, and the fixed arm portions 63c and 63c are extended from the outer end portions of the torsion springs 63a and 63a, and the ends of the fixed arm portions 63c and 63c are extended. The locking portions 63d and 63d are provided by bending the portion.
[0053]
Then, the latching arm portion 63b of the elastic member 63 is engaged with the engaging groove portion 53a of the slide member 53, while the engaging portions 63d and 63d are engaged with the elastic member engaging hole 62c of the slide body 62. The slide body 62 and the slide material 53 are connected, and the slide material 53 and the holder material 52 are slidable in the longitudinal direction of the housing gap.
[0054]
With this configuration, when the casings A and B change in the lateral direction of the casing gap, the slide member 53 slides in this direction in the holder member 52 in the same manner as the casing joint device 1 described above. When the housings A and B change in the longitudinal direction of the housing gap, the slide material 53 and the holder material 52 are moved through the slide body 62 that slides in the slide receiving portion 61. It can slide in the direction to absorb this body variation.
Furthermore, when the housings A and B change in the housing gap depth direction (in this example, the vertical direction), both the holder member 52 and the slide member 53 are attached to the base end side of the housings A and B via elastic members. Therefore, even if either of the casings A and B is moved upward, it can be rotated following this. In addition, since both the holder member 52 and the slide member 53 are urged in the restoring direction via the elastic member, even if the casings A and B are repeatedly fluctuated in the depth direction of the casing gap, they always follow the movement. Can be absorbed.

Example 4
As shown in FIG. 18, the frame joint device 71 is a frame joint device that connects the wall surfaces G3 and ceiling surfaces H2 of the adjacent frames G and H via the frame gap I. Similar to the above-described housing joint device 31, the holder material can be rotated with respect to the housing G by the holder material stopper 34 including the holder material mounting plate 43, the housing fixing plate 44, and the elastic member 45, and the holder material can be restored. On the other hand, in the same manner as the above-described housing joint device 51, the slide material stop portion 54 rotatably attaches the proximal end side of the slide material 53 to the housing H, and urges the slide material 53 in the restoring direction and the housing longitudinally. It can be formed to be slidable in the direction.
