Description

  The present invention relates to a fence configured by disposing a panel between a plurality of support columns erected on an installation surface, and in particular, considering expansion and deformation of the panel due to changes in the outdoor environment such as temperature. Related to the fence.

  Fences that are installed outdoors such as around a house are supported so that the end of the panel can move in the longitudinal direction with respect to the column. According to this type of fence, movement along the longitudinal direction of the panel is not restrained by the support column. For this reason, even when the temperature rises and the panel extends in the longitudinal direction, the end of the panel moves appropriately with respect to the column, and the appearance such as the middle part of the panel being curved in the out-of-plane direction There is no risk of incurring quality problems (for example, see Patent Document 1).

  In the fence configured as described above, even when the panel is deformed in the out-of-plane direction by applying an external force to the panel finding surface, the end of the panel moves in the longitudinal direction with respect to the support column. For this reason, depending on the amount of deformation of the panel, there is a possibility that the end of the panel falls off the support column.

  Here, when the panel is deformed, whether or not the end of the panel falls off the column greatly affects the distance from the end surface of the panel to the place where the panel is supported by the column (hereinafter referred to as “hanging allowance”). Is done. In other words, if a large allowance between the end of the panel and the support is ensured, it is possible to prevent the end of the panel from falling off the support even when the panel is greatly deformed.

  However, the margin between the end of the panel and the column is greatly influenced by conditions such as the size of the column to be applied, the interval between columns, or the location where the fence is installed, and cannot always be secured large. . In particular, in a column that supports two panels with the end surfaces facing each other, it is necessary to secure a space between the end surfaces of the panels so as to absorb expansion deformation, so that the size that can be secured as a hanging margin is significantly limited. In other words, even when a relatively small external force is applied, the end of the panel may easily fall off.

  In view of the above circumstances, the present invention can cope with the expansion and deformation of the panel accompanying a change in the temperature, and even when the hanging margin between the end of the panel and the column cannot be sufficiently secured, It aims at providing the fence which can prevent the situation where an edge part falls from a support | pillar reliably.

  In order to achieve the above object, a fence according to the present invention is a fence configured by disposing a panel across a plurality of support columns erected on an installation surface, and is located at an end of the panel. The column is allowed to move when the end of the panel moves in the direction of increasing the opposing area with respect to the column, and the end of the panel is decreased in the direction of decreasing the opposing area. In the case of movement, an engagement member is provided that contacts the panel and restricts relative movement with the panel.

  According to the present invention, when an external force is applied to the panel and the panel is deformed and the end of the panel moves in the direction of dropping from the column, the engaging member is engaged with the panel, and the end of the panel is dropped from the column. Directional movement is limited.

  According to the present invention, in the fence described above, the panel is formed with a concave portion on a prospective surface thereof to form the engaging portion, and the engaging member has a protrusion at a portion corresponding to the concave portion of the panel.

  According to the present invention, when the end portion of the panel moves in the direction of dropping from the column, the engaging portion of the concave portion provided on the prospective surface of the panel and the engaging portion of the projecting portion provided on the engaging member are in contact with each other. The movement in the direction in which the end portion of the panel falls off the column is limited.

  According to the present invention, in the fence described above, the engagement portion is formed by forming a protrusion on the prospective surface of the panel, and the engagement member has a portion corresponding to the protrusion of the panel. The engagement portion is formed by forming a recess, and the panel is supported by the column in a state where the protrusion of the panel is accommodated in the recess of the engagement member.

  According to the present invention, when the end portion of the panel moves in the direction of dropping from the support column, the engaging portion of the protrusion provided on the prospective surface of the panel and the engaging portion of the recess provided on the engaging member contact each other. The movement in the direction in which the end portion of the panel falls off the column is limited.

  According to the present invention, in the fence described above, the panel is formed with a concave portion on a surface of the panel to form the engaging portion, and the engaging member has a protrusion at a portion corresponding to the concave portion of the panel. The engagement portion is formed by forming the protrusion, and the panel is supported by the column in a state where the protrusion of the engagement member is accommodated in the recess of the panel.

  According to the present invention, when the end portion of the panel moves in the direction of falling off from the support column, the engaging portion of the concave portion provided on the panel mounting surface and the engaging portion of the projecting portion provided on the engaging member contact each other. The movement in the direction in which the end portion of the panel falls off the column is limited.

  According to the present invention, in the fence described above, the engaging portion is formed in the panel by forming a concave portion in a finding surface facing the post, and the engaging member is formed in the concave portion of the panel in the post. The engaging portion is formed by protruding at a corresponding portion, and the panel is supported by the support column in a state where the protruding portion of the engaging member is accommodated in the concave portion of the panel.

  According to the present invention, when the end portion of the panel moves in a direction to drop off from the support column, the engaging portion of the concave portion provided on the panel surface and the engaging portion of the engaging member protruding from each other abut each other.

  Hereinafter, preferred embodiments of a fence according to the present invention will be described in detail with reference to the accompanying drawings.

(Embodiment 1)
FIG. 1 shows a fence according to Embodiment 1 of the present invention. The fence illustrated here is applied to a case where the fence is installed outdoors, for example, around a house, and partitions the internal area and the external area of the site. A plurality of fences standing vertically upward from the installation surface. The support column 10 is provided with a plurality of panels 20 arranged in parallel along the longitudinal direction of the support column 10. The column 10 is a columnar member having a rectangular cross section, and is disposed at a predetermined interval along the boundary of a region partitioned by a fence. The panel 20 is a long flat plate member formed by extrusion molding with a synthetic resin such as polystyrene. Although not clearly shown in the figure, in the first embodiment, the length of the panel 20 is set so that both ends of the panel 20 and the intermediate portion of the panel 20 can be supported by the support surface 11 of the support column 10, respectively. It is set.

  Between the intermediate portion of the panel 20 and the column 10 arranged corresponding thereto, a screw S is fastened to the support surface 11 of the column 10 via a screw insertion hole 21 formed in the panel 20, thereby 20 and the column 10 are connected in a state where relative movement is limited.

  On the other hand, a spacer (engaging member) 30 attached to the support surface 11 of the column 10 and the cover 40 are provided between the end of the panel 20 and the column 10 disposed corresponding to the end of the panel 20. The panel 20 is supported by the support column 10. As shown in FIG. 2A, the two panels 20 whose end faces face each other are in contact with each other even when the panel 20 is stretched and deformed along its longitudinal direction as the temperature rises. A gap d that does not allow is secured.

  As shown in FIG. 1, the spacer 30 is configured such that the protruding height of the support column 10 from the support surface 11 is substantially the same as the thickness of the panel 20 and has the same length as the width of the support surface 11. However, it arrange | positions over between the two panels 20 which an end surface opposes mutually. The spacer 30 is interposed between the panels 20 arranged side by side along the longitudinal direction of the column 10 by fastening screws S to the support surface 11 of the column 10 through screw insertion holes 31 provided at both ends. It is attached to the position to do. Surfaces (hereinafter referred to as “prospect surfaces”) that are positioned above and below the spacers 30 along the thickness direction of the panel 20 are in contact with the probable surfaces of the panels 20 that face each other. It functions to define and maintain the interval.

  The cover 40 is a flat plate member that is formed in a size that covers the end of the panel 20 and the spacer 30. The cover 40 is formed by fastening a screw S to the spacer 30 through a screw insertion hole 41 formed at a position corresponding to the spacer 30, so that the panel 20 is interposed between the support surface 11 of the support column 10 and the pair of upper and lower spacers 30. It is attached to the support | pillar 10 in the state which ensured the accommodation space which accommodates the edge part. In the cover 40, the finding surface facing the support surface 11 of the support column 10 is opposed in the state of being close to the find surface located at the end portion of the panel 20, and the end portion of the panel 20 is separated from the support surface 11 of the support column 10. When moving in a moving direction, it functions to abut and limit its movement.

  On the other hand, between the end portion of the panel 20 and the spacer 30, engagement surfaces (engagement portions) 20A and 30A that can contact each other are provided. In the first embodiment, as shown in FIG. 2A, the concave portion 22 is formed on the prospective surface of the panel 20, and the protrusion 32 is integrally formed on the prospective surface of the spacer 30. By accommodating the protrusions 32 of the spacer 30 in 22, flat engagement surfaces 20 </ b> A and 30 </ b> A that can contact each other are provided between the recesses 22 and the protrusions 32. The recess 22 provided on the panel 20 and the protrusion 32 provided on the spacer 30 are each formed in a rectangular shape in cross section when viewed from the direction of finding, but the protrusion 32 is formed in the longitudinal direction of the panel 20 inside the recess 22. The recess 22 is formed in a large size with respect to the protrusion 32 so that it can move relative to the protrusion 32.

  Here, when the protrusions 32 of the spacers 30 are accommodated in the recesses 22 of the panel 20, the two sets of surfaces can come into contact with each other in each recess 22. That is, the area (hereinafter simply referred to as “opposing area”) of the portion where the end portions of the panel 20 face each other with respect to the support column 10 is reduced between the concave portion 22 of the panel 20 and the protrusion 32 of the spacer 30. There are surfaces 20A and 30A that contact each other when moving in the direction, and surfaces 20B and 30B that contact each other when the end of the panel 20 moves in a direction that increases the opposing area with respect to the support column 10. . However, the engagement surfaces referred to in the first embodiment are the surfaces 20A and 30A that come into contact with each other when the end portions of the panel 20 move with respect to the support column 10 in the direction of reducing the opposing area. In the following, in order to distinguish between the two, the surfaces that abut each other when the end of the panel 20 moves in the direction of increasing the opposing area with respect to the column 10 are referred to as non-engaging surfaces 20B and 30B. To do.

  As apparent from FIG. 2A, the distance between the engagement surface 20A of the panel 20 and the engagement surface 30A of the spacer 30 is the non-engagement surface 20B of the panel 20 in a normal state. And the distance between the non-engaging surface 30B of the spacer 30 is set to be smaller. The distance secured between the non-engaging surface 20B of the panel 20 and the non-engaging surface 30B of the spacer 30 is the same as that of the non-engaging surface 20B of the panel 20 even when the panel 20 is extended and deformed as the temperature rises. The spacer 30 is set so as not to contact the non-engaging surface 30B of the spacer 30.

  According to the fence configured as described above, when the panel 20 is extended and deformed as the temperature rises, that is, as shown in FIG. Move in the direction in which the opposing areas increase, the engagement surface 20A of the panel 20 and the engagement surface 30A of the spacer 30 move in a direction away from each other. As described above, a sufficient gap is secured between the end faces of the panels 20 and between the non-engaging surface 20B of the panel 20 and the non-engaging surface 30B of the spacer 30. Therefore, even when the temperature rises and the panel 20 extends in the longitudinal direction, the end portion of the panel 20 is appropriately moved with respect to the support column 10 so that the deformation of the panel 20 in the longitudinal direction is not hindered. There is no risk of incurring problems in appearance quality such as the panel 20 between the columns 10 being curved in the out-of-plane direction.

  On the other hand, when the end of the panel 20 moves in the direction of decreasing the facing area with respect to the support column 10, the engagement surface 30A of the spacer 30 and the panel 20 are engaged as shown in FIG. The surface 20A comes into contact with each other, and the movement of the end portion of the panel 20 with respect to the column 10 is physically restricted. Therefore, even when the opposing area (hanging allowance) between the end of the panel 20 and the column 10 cannot be sufficiently secured due to the fence installation situation, it is possible to reliably prevent the end of the panel 20 from falling off the column 10 due to external force. It becomes possible to do.

  Therefore, even when the end of the panel 20 moves in the direction of decreasing the facing area with respect to the column 10 to the portion constituting the engagement surface 20A of the panel 20 and the portion constituting the engagement surface 30A of the spacer 30. If the load-bearing performance is secured so that it can withstand without breakage, a stable and stable quality can be secured as a fence.

  Furthermore, the process of providing the concave portion 22 on the prospective surface of the panel 20 may be performed in a factory where the panel 20 is manufactured in advance, but can be easily performed on site using a hand tool as appropriate. Accordingly, even when it is necessary to cut the panel 20 to a desired length at the fence installation site, the recess portion 22 can be newly provided and the protrusion 32 of the spacer 30 can be accommodated thereafter. Excellent workability in

  In the first embodiment described above, the engaging portions 30A are provided on the upper and lower prospective surfaces of the spacer 30 and the engaging portions 20A are provided on the upper and lower prospective surfaces of the panel 20, but this is not necessarily the case. Not exclusively. For example, the engaging portion may be provided only on the prospective surface located above the spacer 30 and the engaging portion may be provided only on the prospective surface located below the panel 20. It is also possible to provide the engaging portion only on the prospective surface located at the top and the engaging portion only on the prospective surface located above the panel 20.

  In the first embodiment described above, the protrusion 32 is formed integrally with the spacer 30, but what is the spacer 30 such as fastening a screw on the prospective surface of the spacer 30 or projecting a pin? You may make it provide a protrusion in another body.

(Embodiment 2)
FIG. 3 shows a fence according to the second embodiment of the present invention. The fence illustrated here is for outdoor use installed by supporting a panel on a column like the first embodiment, and the first embodiment is a configuration of an engaging portion provided between the panel and the spacer. Is different. In the following, description will be made with a focus on differences from the first embodiment, and the same components as those in the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

  As shown in FIG. 4A, in the fence according to the second embodiment, the projections 121 are formed on the prospective surface of the panel 120, the recesses 131 are formed on the expectation surface of the spacer 130, and the recesses 131 of the spacer 130 are formed. By accommodating the protrusions 121 of the panel 120, an engagement portion 120A and an engagement surface (engagement portion) 130A that can contact each other are provided between the protrusion 121 and the recess 131. As the protrusion 121 provided on the prospective surface of the panel 120, as shown in FIG. 3, the head of the screw S that has been fastened is illustrated, but the protrusion 121 may be formed integrally with the panel 120, The protrusion 121 may be provided by protruding a pin instead of the screw S. The recess 131 provided in the spacer 130 is formed to have a large dimension relative to the protrusion 121 so that the protrusion 121 provided on the panel 120 can move relatively along the longitudinal direction of the panel 120. In the second embodiment as well, the engagement portion 120A and the engagement surface 130A are portions that abut each other when the end portions of the panel 120 move in the direction of decreasing the opposing area with respect to the support column 10. is there. In the following, when the end portions of the panel 120 move in the direction of increasing the opposing area with respect to the support column 10, the portions that are close to each other are referred to as the non-engaging portion 120B and the non-engaging surface 130B to distinguish between the two. I decided to. Further, as shown in FIG. 4A, in the normal state, the distance between the engaging portion 120A of the panel 120 and the engaging surface 130A of the spacer 130 is the non-engaging portion 120B of the panel 120. The distance is set smaller than the distance between the non-engagement surface 130B of the spacer 130 and the spacer 130 as in the first embodiment.

  According to the fence configured as described above, the panel 120 is extended and deformed as the temperature rises, and as shown in FIG. In the case of moving in a direction to increase the distance, the engagement portion 120A of the panel 120 and the engagement surface 130A of the spacer 130 move in a direction away from each other. Accordingly, even when the temperature rises and the panel 120 extends in the longitudinal direction, the end of the panel 120 is appropriately moved with respect to the support column 10 so that the deformation of the panel 120 in the longitudinal direction is not hindered. There is no possibility of incurring problems in appearance quality such as the panel 120 between the columns 10 being bent out of plane.

  On the other hand, when the end of the panel 120 moves with respect to the support column 10 in the direction of decreasing the facing area, the engagement surface 130A of the spacer 130 and the panel 120 are engaged as shown in FIG. The portion 120A comes into contact with each other, and the movement of the end portion of the panel 120 relative to the support column 10 is physically restricted. Therefore, even when the opposing area (hanging allowance) between the end portion of the panel 120 and the support column 10 cannot be sufficiently secured due to the fence installation situation, it is possible to reliably prevent the end portion of the panel 120 from dropping from the support column 10 due to external force. It becomes possible to do.

  Therefore, even when the end of the panel 120 moves in the direction of decreasing the facing area with respect to the column 10 to the portion constituting the engagement surface 120A of the panel 120 and the portion constituting the engagement surface 130A of the spacer 130. If the load-bearing performance is secured so that it can withstand without breakage, a stable and stable quality can be secured as a fence.

  In the second embodiment described above, the engaging portions 130A are provided on the upper and lower prospective surfaces of the spacer 130 and the engaging portions 120A are provided on the upper and lower prospective surfaces of the panel 120. Not exclusively. For example, the engaging portion may be provided only on the prospective surface located above the spacer 130 and the engaging portion may be provided only on the prospective surface located below the panel 120. The engaging portion may be provided only on the prospective surface located at the top, and the engaging portion may be provided only on the prospective surface located above the panel 120.

(Embodiment 3)
FIG. 5 shows a fence according to Embodiment 3 of the present invention. The fence illustrated here is an outdoor one installed by supporting a panel on a column, as in the first embodiment.

  The fence of the third embodiment is the same in that the middle portion of the panel 20 and the column 10 disposed corresponding to the middle portion of the panel 20 are fastened with screws S. The panel 20 is supported on the column 10 by a bracket (engagement member) 230 between the portion and the column 10 disposed in correspondence therewith. The bracket 230 is separated from the front end of the support portion 232, a cover portion 231 that covers the finding surface of the panel 20, a pair of support portions 232 that are bent from the upper and lower end portions of the cover portion 231 and covers the prospective surface of the panel 20. And a pair of mounting portions 233 bent in the direction to be integrally formed. The bracket 230 has a mounting interval between a plurality of panels 20 arranged in parallel in the longitudinal direction of the column 10 by fastening screws S to the support surface 11 of the column 10 through screw insertion holes 234 provided in the mounting portion 233. And the state is maintained, and when the end portion of the panel 20 moves in a direction away from the support surface 11 of the support column 10, it functions to abut and limit the movement.

When the protrusion 235 is provided on the support portion 232 of the bracket 230, as shown in the figure, by forming a recess from the outer surface of the support portion 232, the portion facing the prospective surface of the panel 20 can be projected. good. Although not clearly shown in the figure, the recess 22 provided in the panel 20 is larger than the protrusion 235 so that the protrusion 235 of the support portion 232 can move relatively along the longitudinal direction of the panel 20 inside the recess 22. Dimensions are formed. In the third embodiment as well, the engagement surface 20A and the engagement protrusion 230A are portions where the end portions of the panel 20 abut against each other when the end portions of the panel 20 move with respect to the support column 10 in the direction of decreasing the opposing area. It is.

  According to the fence configured as described above, when the panel 20 expands and deforms as the temperature rises, and the end of the panel 20 moves in a direction that increases the opposing area with respect to the support column 10, The engagement surface 20A of the panel 20 and the engagement protrusion 230A of the bracket 230 move in a direction away from each other. Therefore, even when the temperature rises and the panel 20 extends in the longitudinal direction, the end portion of the panel 20 is appropriately moved with respect to the support column 10 so that the deformation of the panel 20 in the longitudinal direction is not hindered. There is no risk of incurring problems in appearance quality such as the panel 20 between the columns 10 being curved in the out-of-plane direction.

  On the other hand, when the end of the panel 20 moves in the direction of decreasing the facing area with respect to the support column 10, the engagement protrusion 230A of the bracket 230 and the engagement surface 20A of the panel 20 come into contact with each other. The movement of the end of the panel 20 with respect to the column 10 is physically restricted. Therefore, even when the opposing area (hanging allowance) between the end of the panel 20 and the column 10 cannot be sufficiently secured due to the fence installation situation, it is possible to reliably prevent the end of the panel 20 from falling off the column 10 due to external force. It becomes possible to do.

  Therefore, when the end of the panel 20 moves in a direction to reduce the facing area with respect to the column 10 to the part constituting the engagement surface 20A of the panel 20 and the part constituting the engagement protrusion 230A of the bracket 230. However, if the load-bearing performance is ensured so that it can be resisted without being damaged, a stable and constant quality as a fence can be secured.

7 and 8 show a fence according to Embodiment 4 of the present invention. The fence illustrated here is an outdoor one installed by supporting a panel on a column like the first embodiment, and the configuration of the engaging portion is different from the first embodiment. In the following, description will be made with a focus on differences from the first embodiment, and the same components as those in the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

  In the fence according to the fourth embodiment, the recesses 321 are formed on the panel 320 and the finding surface facing the support surface 11 of the column 10 and the finding surface facing the cover 40, respectively, and the inside of the support surface 11 of the column 10 and the cover 40 is formed. Protrusions 310 and 410 are provided on the surface, respectively, and the protrusions 310 and 410 are accommodated in the recesses 321 of the panel 320, so that they can be brought into contact with each other between the protrusions 310 and 410 and the recesses 321 ( Engagement portions) 310A, 410A, 320A. The recesses 321 provided on the finding surface of the panel 320 have a groove shape formed along the longitudinal direction of the support column 10 and open to both the upper and lower prospective surfaces of the panel 320. The protrusions 310 and 410 provided on the support surface 11 of the support column 10 and the inner surface of the cover 40 may be formed integrally with the support column 10 and the cover 40, or by attaching a separately formed member. It may also be configured. In the fourth embodiment, protrusions 310 and 410 are configured by attaching a prismatic member formed separately to the support surface 11 of the support column 10 and the inner surface of the cover 40. As shown in FIG. 8, the recess 321 provided in the panel 320 has a large dimension with respect to the protrusions 310 and 410 so that the protrusions 310 and 410 can move relatively along the longitudinal direction of the panel 320. It is formed. In the fourth embodiment, the engagement surfaces 310A, 410A, and 320A are surfaces that come into contact with each other when the end portions of the panel 320 move with respect to the support column 10 in the direction of decreasing the opposing area. . In the following, when the ends of the panel 320 move with respect to the support column 10 in the direction of increasing the opposing area, the surfaces that contact each other will be referred to as non-engaging surfaces 310B, 410B, and 320B to distinguish them from each other. And In the normal state, the distance between the engagement surface 320A of the panel 320 and the engagement surfaces 310A and 410A of the support column 10 and the cover 40 is such that the non-engagement surface 320B of the panel 320, the support column 10 and the cover 40. The distance between the non-engaging surfaces 310B and 410B is set to be smaller than that of the first embodiment. Reference numeral 330 in FIG. 7 abuts against the prospective surface of the panel 320, thereby defining and maintaining the mounting interval of the plurality of panels 320 arranged in parallel along the longitudinal direction of the support column 10. It is a spacer that functions as follows.

  According to the fence configured as described above, the panel 320 expands and deforms as the temperature rises, and when the end of the panel 320 moves in a direction that increases the opposing area with respect to the support column 10, The engagement surface 320A of the panel 320 and the engagement surfaces 310A and 410A of the support column 10 and the cover 40 are moved away from each other. Therefore, even when the temperature rises and the panel 320 extends in the longitudinal direction, the end portion of the panel 320 is appropriately moved with respect to the support column 10 so that the deformation of the panel 320 in the longitudinal direction is not hindered. There is no risk of incurring problems in appearance quality such as the panel 320 between the columns 10 being bent out of plane.

  On the other hand, when the end of the panel 320 moves in a direction that reduces the facing area with respect to the support column 10, the engagement surfaces 310A and 410A of the support column 10 and the cover 40 and the engagement surface 320A of the panel 320 are in contact with each other. As a result, the movement of the end portion of the panel 320 with respect to the column 10 is physically limited. Therefore, even when the facing area (hanging allowance) between the end of the panel 320 and the column 10 cannot be sufficiently secured due to the fence installation situation, it is possible to reliably prevent the end of the panel 320 from falling off the column 10 due to external force. It becomes possible to do.

  Therefore, the end portion of the panel 320 reduces the facing area to the portion constituting the engaging surface 320A of the panel 320 and the portion constituting the engaging surfaces 310A and 410A of the support column 10 and the cover 40. If the load-bearing performance is ensured so that it can be resisted without breakage even when moving, a stable and constant quality as a fence can be secured.

  In the above-described fourth embodiment, the engagement surfaces 310A and 320A are provided between the support surface 11 of the support column 10 and the finding surface of the panel 320, and between the inner surface of the cover 40 and the finding surface of the panel 320. Since the engagement surfaces 410A and 320A are provided on the upper surface, it is possible to set the load-bearing performance relating to the dropping of the panel 320 higher, but either between the support column or the cover. You may make it provide.
