Description

  The present invention relates to an expansion joint device for connecting a plurality of fence members to absorb and maintain the connection when an external force is applied to each fence member to generate a displacement. It can cope with displacement.

  When an external force is applied to a building with a different structure, such as an adjacent building, due to vibration, temperature change, non-uniform subsidence (non-uniform subsidence), earthquake, etc. May cause trouble in use. For example, there is a fence that spans adjacent buildings, and when earthquake motion is transmitted to this part, the vibration characteristics of one building and the other building are different, so the movements that occur in each fence differ, and the fences interfere with each other. There is a risk of crashing or damage.

  In such a case, conventionally, a method has been adopted in which a column is installed in each building with an expansion joint sandwiched, a short panel member is fixed to the column, a gap is formed between the panel members, and a displacement is accommodated. It was. However, when the support is installed across the expansion joint, the sense of unity as a design is lost, the landscape image of the installation location is impaired, and the function as a fence and the security function are weakened. The above problem is not limited to fences that extend between adjacent buildings, but also applies to fences or similar structures that are installed on the ground as so-called exteriors.

  For example, Japanese Patent Application Laid-Open No. 2003-247278 was found when prior art related to the above problem was investigated. This relates to an expansion handrail of a seismic isolation building, and has an arrangement in which the expansion handrail is attached by a free hinge of a general part handrail, and the expansion handrail and the general part handrail have the same structure. However, even if there is no sense of design discomfort due to the above configuration, the expansion handrail is attached to the handrail of the general part in a cantilevered manner, so that the strength is insufficient and the construction object is considered to be limited.

  Japanese Patent Application Laid-Open No. 9-317118 discloses that a first handrail and a second handrail are connected to each other, the first handrail is rotatable to a structure, and the second handrail is a guide member. It can be slidably mounted along and can absorb the difference between the respective displacements. However, since the second handrail is fixed to the building, the first handrail is attached to the building so as to be cantilevered and swingable. For this reason, there exists a problem similar to the said invention, and since it attaches directly to the adjacent part of a building, it is difficult to apply, for example about the fence installed so that a building may be surrounded.

  In particular, when the influence of uneven ground subsidence or earthquake motion is applied to a building, the displacement includes not only the X-Y plane but also the Z-axis, that is, the vertical (vertical) component. On the other hand, Japanese Patent Laid-Open No. 11-324267 is known to have a displacement followability in the vertical direction, but the invention of the same number only combines one handrail member with a column by pin connection. . Therefore, it cannot be said that it corresponds to the displacement of the horizontal plane caused by the vertical displacement and may not be able to follow the vertical displacement, but its limit is very low, and if it exceeds the limit, it easily breaks It is guessed.

JP 2003-247278 A JP-A-9-317118 JP-A-11-324267

  The present invention has been made in view of the above circumstances, and the problem is that in fences configured by connecting a plurality of fence members, an external force is applied to each fence member, and in the plane and in the vertical direction (vertical direction). An expansion joint device is provided that can absorb the displacement and maintain the connection even when the displacement occurs. Another object of the present invention is an expansion joint device that is suitable for fences installed so as to surround a building without impairing the landscape image, and in particular, can exhibit an effective intrusion prevention function required for the fences. Is to provide.

  In order to solve the above-described problems, the present invention provides an expansion joint that is constructed by connecting a plurality of fence members to absorb and maintain a connection when an external force is applied to each fence member. About the apparatus, the 1st support | pillar installed in the 1st support | pillar installed in the 1st support | pillar, the 2nd support | pillar installed in the 2nd installation proof, the 1st support | pillar at the base end, and the 1st A second guide member that has a tip part that overlaps with the tip part of the fence member and a connecting part of the fence member, is attached to the second support column at the base end part, a vertical guide part that has a long groove in the vertical direction, and left and right parts A horizontal guide portion having a long groove in the direction, and either one of the vertical guide portion or the horizontal guide portion is provided on the tip end side of the first fence member, and either of the vertical guide portion or the horizontal guide portion is provided. Or the other side is provided on the tip side of the second fence member, As an arrangement configuration in which the long groove in the lower direction and the long groove in the left-right direction intersect, a movable shaft that can move in the vertical and horizontal directions along the two long grooves is disposed at the intersection of the two long grooves, and the movable shaft is coupled to the means. As a measure, the first fence member and the second fence member are configured to be connected so that the movement in the vertical and horizontal directions between the first installation location and the second installation location can be absorbed. It is.

  The fences in the present invention are configured by connecting a plurality of fence members, and specifically, the fences are configured as a minimum set of the first fence member and the second fence member. The first fence member is attached to the first support column, and the second fence member is attached to the second support column. The first support column is installed at the first installation site, and the second support column is installed at the second installation site. The first installation site is, for example, one of the adjacent buildings, The installation location is, for example, the other of the adjacent buildings. Moreover, since this invention can be applied also to the fence installed in the ground as an external structure or a similar structure, the 1st installation location and the 2nd installation location are adjacent in the same ground. It can be said that two installation locations also apply. In short, the joint device of the present invention is applied to all cases where the joint device is installed across or across different installation locations.

  The apparatus of the present invention has a vertical guide portion having a long groove in the vertical direction and a horizontal guide portion having a long groove in the left-right direction. The vertical guide part absorbs the displacement of the component in the Z axis, that is, the vertical direction, and the horizontal guide part absorbs the displacement in the XY plane. Either one of the vertical guide portion or the horizontal guide portion is provided on the distal end side of the first fence member, and either one of the vertical guide portion or the lateral guide portion is provided on the distal end side of the second fence member. Shall. Further, as an arrangement configuration in which the vertical groove of the vertical guide member and the horizontal groove of the horizontal guide member intersect each other, it can move in the vertical and horizontal directions along the two long grooves at the intersection of the two long grooves. A movable shaft shall be arranged. Then, the first fence member and the second fence member are connected so that the movable shaft can be used as a coupling means to absorb the movement in the vertical and horizontal directions between the first installation location and the second installation location. Configure.

  The vertical groove of the vertical guide member and the horizontal groove of the horizontal guide member intersect with each other, and a single movable shaft is arranged at the intersecting portion of the long groove, so that the movable shaft receives an external force and moves up and down. It moves freely in the long slot in the direction and the long slot in the left and right direction, and absorbs complex external force. In addition, the movable shaft is a coupling means for the vertical guide member and the horizontal guide member, and the flat element to which no external force acts functions as a part of fences configured by connecting a plurality of fence members. Further, the vertical guide member and the horizontal guide member can be formed to have arbitrary dimensions as long as they can fit within the width in the left-right direction of the first fence member and the second fence member. The amount corresponding to can be set large.

  In the joint device of the present invention, the first fence member and the second fence member are overlapped on the left and right at the respective distal end portions, and the first fence member and the second fence are overlapped at the overlapping portion. The member can be translated while maintaining linearity, and in the overlapping portion of the first fence member and the second fence member, either of the other fence members with respect to the tip of one of the fence members By having a bent portion shifted forward and backward by the amount of overlap of the fence member on the tip end side, an absorption space in the left-right direction is formed between the tip portion and the bent portion of the first fence member. Such provision is one desirable configuration. Thereby, since an action line can be guide | induced in a straight line shape about the external force of the left-right direction applied to the joint apparatus of this invention, a 1st fence member and a 2nd fence member do not bend by receiving an external force.

  Moreover, the front-end | tip part of the 1st fence member has reached the approximate center part of the space | interval of a 1st support | pillar and a 2nd support | pillar, and the front-end | tip part side of a 2nd fence member is the front-end | tip of a 1st fence member. A position that is longer than the section side and extends to a position that exceeds the center section, a vertical guide section is provided at a position that is approximately one half of the height at the tip of the first fence member, and a position that exceeds the center section The horizontal guide portion is provided at a position substantially half the height on the tip end side of the second fence member extending in the vertical direction so that the vertical guide portion and the horizontal guide portion are the first support column and the second support column. It is also a desirable configuration aspect to provide a cross at approximately the center of the distance between the two. The configuration in which the vertical guide portion and the horizontal guide portion cross each other at the substantially central portion of the distance and height between the first support column and the second support column is only one place between the first and second support columns. However, if the expansion joint device is provided at one location, the processing of the external force will be simplified and it will be easier to absorb the displacement. Moreover, you may comprise the expansion joint apparatus which couple | bonds a 1st fence member and a 2nd fence member with two or more, In that case, the integrity of fence members gives priority to the absorbability of a displacement. It will be. However, this is a matter that can be appropriately set in accordance with the installation portion and purpose within the scope of the present invention.

  Since the present invention is configured as described above, in a fence configured by connecting a plurality of fence members, as an arrangement configuration in which a long groove in the vertical direction intersects with a long groove in the left-right direction, the intersection of the two long grooves In addition, since a movable shaft that can move in the vertical and horizontal directions along the two long grooves is arranged, even when external force is applied to each fence member to cause displacement in the plane and in the vertical direction, this is absorbed and connected. There is an effect that an expansion joint device capable of maintaining the above can be provided. Further, according to the present invention, an expansion joint device that is suitable for fences installed so as to surround a building without impairing a landscape image, and in particular, that can exhibit an effective intrusion prevention function required for the fences is provided. be able to.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of an expansion joint device 10 in a fence according to the present invention. A first support column 13 is installed at a first installation location 11 and a second support column 12 is installed at a second installation location 12. 14 is shown as being installed. The first installation location 11 is, for example, one of the adjacent buildings, and the second installation location 12 is, for example, the other of the adjacent buildings, and there is a space or space 34 between them. It is assumed that the first and second installation locations 11 and 12 can vibrate independently. The said 1st installation location 11 and the 2nd installation location 12 are not restricted to a building, For example, the location set to two arbitrary points on the ground may be sufficient.

  The support columns 13 and 14 in the embodiment are bilaterally symmetric as shown in FIG. 1 and the like, and the mounting positions and the like are different on the left and right as shown, but what should be provided is the same on the left and right. Therefore, the left and right members will be described separately with reference to L, R, etc., if necessary. In each figure, the building member side mounting pieces 15L and 15R and the joint side mounting pieces 16L and 16R are attached to the left and right with a slight difference in the upper and lower sides on the upper portions of the left and right support columns 13 and 14, respectively. The member side mounting pieces 17L and 17R and the joint side mounting pieces 18L and 18R are provided at substantially the same position on the left and right. In addition, the support | pillars 13 and 14 are made to incline inside so that it may turn over in the support | pillar top parts 13a and 14a, and this is improving the crime prevention function.

  Building member side fence members 35L, 35R are attached to the building member side attachment pieces 15L, 15R, 17L, 17R on the upper, lower, left, and right sides by attachment means 19L, 19R indicated by bolts (FIGS. 2 to 4). Further, the first fence member 21 and the second fence member 22 are respectively attached to the joint-side attachment pieces 16L, 16R, 18L, and 18R on the upper, lower, left, and right sides by attachment means 20L and 20R indicated by the same bolting. ing. The attachment means 19L, 19R, 20L, and 20R maintain the alignment of the first fence member 21, the second fence member 22, and the building member side fence members 35L and 35R in a straight line.

  Since the expansion joint apparatus 10 in the embodiment is installed as a part of a fence installed in a building, the building side of the building member side mounting pieces 17L and 17R is installed in the above building. Means the fence side. Therefore, the joint side of the joint side attachment pieces 18L and 18R means the side of the joint member of the expansion joint device 10 of the present invention (a plurality of fence members constituting fences in the device of the present invention). The support columns 13 and 14 are installed on the mounting portions 11a and 12a of the first installation location 11 and the second installation location 12 in the support base portions 13b and 14b. However, when the first installation location 11 and the second installation location 12 are two arbitrary locations on the ground, the columns 13 and 14 are installed on the attachment portions 11a and 12a at the respective positions. Anyway, the said 1st fence member 21 and the 2nd fence member 22 are fixed to the support | pillars 13 and 14, and maintain linearity with the building member side fence members 35L and 35R in that state. Yes.

  The first fence member 21 according to the present invention has such a length that the tip portion reaches the substantially central portion of the distance between the first support column 13 and the second support column. As for the fence member 22, the front-end | tip part is longer than the front-end | tip part side of the 1st fence member 21, and is extended even to the position exceeding the said center part (FIG. 1, FIG. 2). That is, the first fence member 21 and the second fence member 22 overlap each other on the front end side, and in the overlapping part of the first fence member 21 and the second fence member 22, A bent portion 14c formed in a crank shape is formed on the distal end side of the other fence member 22 with respect to the distal end portion of the other fence member 21 by being shifted forward and backward by an overlap amount. With the above configuration, an absorption space S in the left-right direction is formed between the distal end portion 13c of the first fence member 13 and the bent portion 14c of the second fence member 14 (FIGS. 2 and 7). ).

  The first fence member 21 is configured by combining a vertical beam 23 in the vertical direction arranged in the left and right direction and upper and lower horizontal beams 24A and 24B extending in the horizontal direction in a cross shape. The second fence member 22 is also basically configured by combining a vertical beam 25 in the vertical direction arranged in the left and right direction and upper and lower horizontal beams 26A and 26B extending in the horizontal direction in a cross shape (FIG. 11). (See also FIG. 14). The vertical bars 23 and 25 have top portions 23a and 25a inclined inward with respect to the straight main body portion. This top slope shape is the same as the side face shape of the support columns 13 and 14 (the top 25a of the second fence member is provided only in a part on the building member side). The horizontal rails 24A, 24B, 26A, and 26B are formed by arranging a T-shaped section material at the upper part and an inverted T-shaped member at the lower part (FIGS. 5 and 6). 5 and 6, reference numerals 27A, 27B, 28A, and 28B are reinforcing members made of I-shaped members, and are provided to reinforce the bent portion 14c.

  In the illustrated embodiment, a vertical guide portion 30 having a long groove 29 in the vertical direction and a horizontal guide portion 32 having a long groove 31 in the left-right direction are provided on the first fence member 21 side. As shown in detail in FIGS. 7 to 10, the vertical guide portion 30 is connected to the adjacent vertical members 23, 23 on the distal end side in the left-right direction of the first fence member 21 by welding or the like. (Fig. 7). The position of the vertical guide portion 30 is set to approximately one half of the height at the distal end portion of the first fence member 21. Further, the lateral guide portion 32 is attached to the two vertical members 25 and 25 by means of welding or the like at a position that is almost a half of the height on the distal end side of the second fence member 22. (FIGS. 7 and 8). Therefore, the vertical guide portion 30 and the horizontal guide portion 32 are configured to cross each other at substantially the center of the distance and height between the first support column 13 and the second support column 14.

  The vertical guide portion 30 shown in the embodiment is formed of a channel-shaped member having a U-shaped cross-sectional shape, and the horizontal guide portion 32 is formed of a horizontally long frame-shaped member and has bent portions at both ends, so that it is elongated. It is U-shaped. The vertical guide portion 30 and the horizontal guide portion 32 are attached to the first fence member 21 and the second fence member 22 in an arrangement in which each U-shape is back-to-back. The lengths of the long grooves 29 and 31 of the vertical guide portion 30 and the horizontal guide portion 32 are set to be approximately the same, and the half length of the long groove 31 is the left-right direction of the absorption space S. It is set shorter than the length. As an example, the lengths of the long grooves 29 and 31 of the vertical guide portion 30 and the horizontal guide portion 32 are plus or minus 300 mm on the basis of the positional relationship shown in FIG. 1, and a total of about 600 mm is absorbed. It is set to be possible.

  In this manner, the longitudinal groove 29 in the vertical guide portion 30 and the long groove 31 in the left-right direction of the lateral guide portion 32 are arranged to cross each other, and the movable shaft 33 is formed at the intersecting portion of the long grooves 29, 31. Be placed. The movable shaft 33 is composed of one bolt-shaped shaft in the illustrated example, and the shaft passes through the long grooves 29 and 31 and uses the required washer 34a, the spacer 34b and the nut 34c, and the first fence member 21. And the second fence member 22 are connected. As described above, the movable shaft 33 is configured to be movable in the vertical and horizontal directions along the long grooves 29 and 31. A slight gap g is provided between the vertical guide portion 30 and the horizontal guide portion 32.

  Next, the operation of the expansion joint device 10 in the fences of the present invention having the above-described configuration will be described with reference to the drawings. As shown in FIG. 1, the expansion joint device 10 of the present invention has a first support column 13 installed at a first installation site 11 and a second support column 14 installed at a second installation site 12. The first fence member 21 is attached to the support pillar 13 side, the second fence member 22 is attached to the second support pillar 14 side, and the first fence member 21 and the second fence member 22 are movable. Using the shaft 33 as a coupling means, the first installation location 11 and the second installation location 12 are connected so as to absorb the movement in the vertical and horizontal directions. Moreover, it is connected with the fence members 35L and 35R which are the fences of a building part in the location of the 1st support | pillar 13 and the 2nd support | pillar 14 installed in the 1st and 2nd installation location 11 and 12. When no external force is applied, the first fence member 21 and the second fence member 22 are connected to each other, so that the fence serves as a fence between buildings and plays a role in security and crime prevention.

  When an external force is transmitted to the first installation location 11 and the second installation location 12 due to seismic motion or the like with respect to the expansion joint device 10 of the present invention, each attached to the first support column 13 and the second support column 14. The fence members 21 and 22 are displaced by an external force, and move relatively in the vertical and horizontal directions and in the front and rear direction. FIG. 11 shows a movement example 1 in which the first fence member 21 and the second fence member 22 are separated from each other left and right, and a space (or interval) 34 is widened. Shows a state where the second fence member 22 is raised and the positional deviation is caused. That is, according to the apparatus 10 of the present invention, the displacement on the horizontal plane (XY plane) and the vertical plane (Z-axis direction) is absorbed by the above movement. Taking the above-mentioned numerical value as an example, in FIG. 11, the first fence member 21 or the second fence member 22 moves about 300 mm in the vertical direction, and about 300 mm apart in the left-right direction. This is absorbed by the expansion joint device 10.

  FIG. 12 shows a movement example 2 opposite to that in FIG. 11. The first fence member 21 and the second fence member 22 approach each other, the space 34 is narrowed, and the first fence member is relatively moved. 21 shows a state in which the second fence member 22 has moved down and a positional deviation has occurred. By this movement, the displacement in the horizontal plane (XY plane) and the vertical plane (Z-axis direction) is absorbed, but the space 34 narrows so that a part 22 ′ of the second fence member 22 collides with the first installation location 11. It is necessary to consider the possibility of doing. Assuming such a case, in the present invention, the escape portion 22a corresponding to the part 22 'of the fence member 22 can be provided in advance, and the long groove in the left-right direction is taken into account in consideration of the size of the space 34. By determining the length of 31, collisions can be avoided or damage can be minimized. In the case of a general site, the necessity of providing a relief portion is determined according to the situation at the construction site.

  FIG. 13 illustrates displacement absorption for movement in only the left-right direction when an external force is transmitted to the first installation location 11 and the second installation location 12. FIG. 13B corresponds to FIG. 1 and shows a reference state in which the first fence member 21 and the second fence member 22 are not separated from each other and are not approached. 13A shows a separated state corresponding to FIG. 11, and FIG. 13C shows an approached state corresponding to FIG. 12, which is the expansion or narrowing of the positional relationship between the first fence member 21 and the second fence member 22. Therefore, since the absorption space S changes widely, it will be easily grasped visually. Further, it will be understood that the displacement in the left-right direction can be grasped as a relative movement of the second fence member 22 when the first fence member 21 is fixed in FIG.

  FIG. 14 illustrates displacement absorption with respect to movement when an external force in the front / rear and left / right directions is transmitted to the first installation location 11 and the second installation location 12. In FIG. 14B, the 1st fence member 21 and the 2nd fence member 22 approach, and the shift | offset | difference has arisen also in the front-back. That is, in FIG. 14A, the approach, that is, the lateral displacement and the longitudinal displacement are combined, and the device 10 of the present invention is displaced obliquely. However, even when such complicated movement is involved, According to the apparatus 10, the movable shaft 33 freely slides in the long grooves 29 and 31, and the absorption space S can be changed widely, so that deformation or breakage does not occur. FIG. 14B shows a state in which the first fence member 21 and the second fence member 22 are separated from each other and are also displaced in the front-rear direction. In this case, the same displacement absorption effect as when approaching can be obtained. Will be easily understood.

  The present invention is configured as described above, and when the seismic motion is transmitted to the fence portion provided between adjacent buildings, the vibration characteristics of one building and the other building are different, and the movements generated in each fence are different. However, between the first fence member 21 and the second fence member 22 installed in each building, there is a long groove 29 in the vertical direction of the vertical guide portion 30 and a long groove 31 in the horizontal direction of the horizontal guide portion 32. Since the intersecting arrangement is adopted and the movable shaft 33 movable in the vertical and horizontal directions is disposed and coupled to the intersecting portion of the long grooves 29 and 31, the displacement can be absorbed. Accordingly, it is possible to prevent the first and second fence members 21 and 22 from interfering with each other and colliding with each other or being damaged. It is suitable as an expansion joint device for fences such as buildings, and it is also possible to prevent damage to the fence itself by absorbing the displacement. Therefore, secondary damage due to falling components etc. is effectively prevented as a result of damage. .
