Description

  The present invention relates to an improvement of a fence used as a fence for a general house or as a fence for a condominium or a general house, such as a terrace or a roof, and realizes a structure in which the design is not limited by the pitch of the columns. .

  6 to 11 show two examples of fences used as fences for ordinary houses or as fences for terraces and rooftops. These fences 1 and 1a are constructed on the upper surface of the base 2 such as a relatively low waist or bank made of concrete blocks (for example, in the case of a fence) or reinforced concrete (for example in the case of a fence). In order to construct the fences 1, 1 a, a plurality of support columns 3, 3 a are fixed to the upper surface of the base 2 in the vertical direction at intervals in the horizontal direction, and the plurality of support columns 3, 3 a A handrail 4 is stretched over the upper end.

  In the case of the structure of the first example shown in FIGS. 6 to 8, the upper surfaces of the lower frames 5, 5 and the lower surface of the handrail 4 spanned between the lower end portions of the intermediate columns 3 and 3. A plurality of ribs 6 and 6 are stretched between them. On the other hand, in the case of the structure of the second example shown in FIGS. 9 to 11, a plurality of ribs 6 and 6 are spanned between the lower surface of the upper frame 7 and the upper surface of the lower frame 5a. Both end portions of the plurality of panel units 8, 8 are supported and fixed to the support columns 3a, 3a by brackets 9, 9, respectively.

  In any structure, the design of the fences 1 and 1a is greatly influenced by the presence of the columns 3 and 3a, as is apparent from FIGS. On the other hand, the interval (pitch) between the columns 3 and 3a is generally made as wide as possible within a range that can secure the necessary and sufficient strength for the fences 1 and 1a. Therefore, in the case of the conventional structure, the design of the fences 1 and 1a is limited based on the presence of the support columns 3 and 3a.

  On the other hand, Patent Document 1 describes a fence 1b having a structure as shown in FIGS. In the fence 1b of the third example of the conventional structure, a single lower frame 10 is hung between the support columns 3 and 3 between the support columns 3 and 3 in the middle of the support columns 3 and 3 at a position slightly above the upper surface of the base 2. It is fixed to pass. In addition, one upper frame 11 is fixed between the upper ends of the columns 3 and 3 so as to span between the columns 3 and 3 and in parallel with the lower frame 10. ing. The lower frame 10 holds the lower edge portions of the plurality of panel units 12 and 12, and the upper frame 11 holds the upper edge portions of the panel units 12 and 12.

  In the case of such a structure described in Patent Document 1, the fence 1b is taken from the outside (from the side opposite to the side where the support columns 3 and 3 are installed), as is clear by comparing FIGS. ) The pillars 3 and 3 are not noticeable when viewed. Therefore, the degree of freedom in design of the fence 1b is improved regardless of the interval (pitch) between the adjacent columns 3 and 3. However, there is room for improvement in terms of facilitating construction work or repair work. This is because it is necessary to engage and disengage the upper edge of the plurality of panel units 12 and 12 constituting the fence 1b with the upper frame 11 simultaneously. is there.

  That is, each of the panel units 12 and 12 is supported at the upper edge by being held by the upper frame 11. In a state before the upper frame 11 is installed, it is difficult for the panel units 12 and 12 to stand independently in the vertical direction simply by holding their lower end edges on the upper surface of the lower frame 10. Therefore, in order to hold the upper edge of each panel unit 12, 12 by the upper frame 11, the panel unit 12, 12 is positioned in the same plane, 12 is required to cover the upper frame 11. It is difficult to perform such work by one worker. Further, when one of the plurality of panel units 12 and 12 is damaged and replaced, when the upper frame 11 is removed, the upper frame 11 supports the upper edge of each. The supporting force of the upper edge of all the panel units 12 and 12 made is lost. As a result, the panel units 12 and 12 are not positioned in the vertical direction, so that it is difficult for one worker to replace the damaged panel unit as in the case of new construction work. .

Japanese Patent Laid-Open No. 11-125037

  In view of the circumstances as described above, the present invention was invented to realize a fence structure in which the design is not easily influenced by the interval (pitch) of the support columns and the construction work and the repair work can be performed by a small number of people. is there.

Each of the fences of the present invention includes a plurality of support columns, a single lower frame, a single upper frame, and a plurality of panel units in the same manner as the fence described in Patent Document 1 described above. Prepare.
Each of these columns is fixed in the vertical direction with a space in the horizontal direction.
Further, the lower frame is spanned between the intermediate portions of the respective struts so as to protrude to the front side with respect to the respective struts, and has a cross-sectional shape with an upper opening.
The upper frame is spanned between the upper portions of the support columns so as to protrude to the front side of the support columns, and has a cross-sectional shape with an open bottom.
Further, each of the panel units is held by a lower end edge of the panel unit on the lower frame and an upper end edge of the panel unit on the upper frame.
In particular, in the fence of the present invention, the upper frame is spanned between the upper ends of the columns, with the front half projected from the columns to the front side. Moreover, the cross-sectional shape of this front half is an open shape at the bottom.
Further, an upper collar and a lower collar are respectively provided at the upper edge and the lower edge of each panel unit. Of these, the upper arm is held by the front half of the upper frame. On the other hand, the lower collar has a lower support provided in a state in which the upper surface side end portion and the rear surface side end portion of the lower surface thereof are in contact with the lower frame, respectively , with the upper portion opened to the lower frame. It is held in the holding groove.
Further, the upper collar and the lower collar are coupled and fixed to the upper frame and the lower frame, respectively, by fixing screws.

  Note that the front side of each support column is a side that places importance on the design as a fence, and generally speaking, it means the road side in the case of a fence and the outdoor side in the case of a fence. In addition, the single lower frame and the upper frame mean that the lower edge and the upper edge of the plurality of panel units are supported by a single lower frame and an upper frame, respectively. Naturally, the total length of these lower and upper frames is limited in consideration of transportation (in consideration of the truck bed length). Therefore, when constructing a fence exceeding 3 m or 5 m for small-scale construction, and when constructing a fence exceeding 10 m for large-scale construction, naturally, the lower frame and the upper frame are long. It consists of a plurality of frame members connected in series in the vertical direction. Even in this case, if the edge portions of a plurality of panel units are supported for each frame member, the condition that the number of the lower frame and the upper frame is one is satisfied.

When carrying out the present invention, for example, as in the invention described in claim 2, the upper holding groove provided in the upper frame in a state of opening downward to hold the upper edge of each panel unit. the depth to these and consuming margin regarding the vertical direction of the upper edge of each panel unit, a vertical direction about the consuming cost and total depth or more of the lower edge and the lower frame of each panel unit . Then, by ensuring the depth of the upper holding groove portion in this way, each panel unit is built (in a so-called “Kendon type”) between the lower frame and the upper frame installed in advance, and further, both the frames to be held between the adjacent.

Alternatively, as in the invention described in claim 3, the upper frame, constituted by a coupling portion and a coping portion. Binding portion of this, together with the coupled fixed to the upper end of each strut, and that the upper edge of each panel unit to screwed. In addition, the top portion of each panel unit can be attached to and detached from the coupling portion in a state where the upper end edge portion of each panel unit is coupled and fixed to the coupling portion. Cover the part.

According to the fence of the present invention configured as described above, the design can be hardly affected by the interval (pitch) between the columns . Moreover, according to the second and third aspects of the invention, construction work and repair work can be performed by a small number of people.
First, since each panel unit is built between the upper and lower frames provided between the columns so as to protrude to the front side of the columns, most of the columns are made up of the panels. It hides behind the unit and does not appear on the front side that emphasizes the design (not noticeable). Therefore, when considering the design of the fence, it is not necessary to associate the width and pitch of each panel unit with the pitch of each column. As a result, the degree of freedom in design design is improved.
Under Further, even if any structure as claimed in claim 2, in which the upper edge of each panel unit, independently for each respective panel unit, was stretched between advance between each strut It can be built between the frame and the top frame. For this reason, construction work and repair work can be performed by a small number of people.

[First example of embodiment]
1 to 4 show a first example of an embodiment of the present invention corresponding to claims 1 and 2 . The fence of this example includes a plurality of support columns 13, 13, one lower frame 14, one upper frame 43, and a plurality of panel units 15, 15.
Each of the columns 13 and 13 is spaced apart from each other in the horizontal direction (left and right in FIGS. 1, 2, and 4) on the upper surface of the concrete base 2, such as a relatively low waist or bank. It is fixed in the vertical direction (vertical direction). In the case of this example, each of the struts 13 and 13 has a steel or stainless steel and tubular internal strut 16 with its lower end embedded in and fixed to the base 2, and the internal strut 16 is not rattled. The outer support column 17 is made of an aluminum alloy extruded mold and fitted to the inner support column 16 by rivets.

  In addition, the lower frame 14 is positioned between the lower end portions of the middle portions of the support columns 13 and 13 from the front side of the support columns 13 and 13 (on the side that emphasizes the design as a fence. 2, the lower side of FIG. 2, and the left side of FIG. 3). For this reason, in the case of this example, a horizontal T-shaped mounting bracket 18 is screwed and fixed to the surface side near the lower end of the middle portion of each of the columns 13 and 13, and the lower frame is mounted on the upper surface of the mounting bracket 18. 14 is supported and fixed. The lower frame 14 is made of an aluminum alloy extruded mold and has a cross-sectional shape with an upper opening. In the case of this example, a pair of horizontal plate portions 19 and 19 projecting in a direction approaching each other from the same height position of both inner side surfaces of the lower frame 14 are provided at the middle portion in the vertical direction of the lower frame 14. The lower plate holding groove 20 for holding the lower edge of each of the panel units 15 and 15 is formed above the horizontal plate portions 19 and 19.

  The upper frame 43 is stretched between the upper ends of the columns 13 and 13 so as to protrude to the front side of the columns 13 and 13. For this reason, in the case of this example, the central portion of the flat support plate 21 is fixed to the upper end portions of the columns 13 and 13 by a plurality of tapping screws 22 and 22. The length dimension of the support plate 21 with respect to the length direction of the upper frame 43 (the left-right direction in FIGS. 1, 2, 4 and the front-back direction in FIG. 3) Is also big. Accordingly, both end portions in the length direction of the support plate 21 protrude from both side surfaces of the support columns 13 and 13. The upper frame 43 is formed by a plurality of set screws 23, 23 inserted through both ends in the length direction of the support plate 21 from below, and the upper end portions of the support columns 13, 13 through the support plate 21. Is supported and fixed.

In this way, the front half of the upper frame 43 supported and fixed to the upper ends of the columns 13 and 13 protrudes (overhangs) from the columns 13 and 13 to the front side. And the upper holding groove part 24 which the lower part opened is provided in the lower surface of the said upper frame 43 in the part protruded to the front side rather than these each support | pillars 13 and 13. FIG. In the case of this example, the depth H ₂₄ of the upper holding groove 24 is made sufficiently larger than the depth required to hold the upper edge of each panel unit 15, 15. Specifically, the depth H ₂₄ is defined by the vertical allowance H _H between the upper edge of each panel unit 15, 15 and the upper holding groove 24, and the lower end of each panel unit 15, 15. The depth is equal to or greater than the total sum of the vertical allowances H _L between the edge and the lower frame 14 (H ₂₄ ≧ H _H + H _L ). Then, by securing the depth H ₂₄ of the upper holding groove portion 24 in this way, the panel units 15 and 15 are built between the lower frame 14 and the upper frame 43 that are installed in advance. These frames 14 and 43 can be held between each other.

  Each of the panel units 15 and 15 is installed between the upper holding groove portion 24 and the lower holding groove portion 20 as described above, in the same manner as a general sliding door type sliding door shoji or glass shoji. It is built in a certain Kendon style. In the case of this example, each of the panel units 15, 15 is formed by surrounding the rectangular glass panel 25 around the upper periphery 26, the lower end 27, and the left and right ends 28, 28. Each of the panel units 15 and 15 holds the lower collar 27 positioned at the lower edge of the panel unit 15 in the lower holding groove 20 and the upper collar 26 constituting the upper edge of the panel unit 15. It is built between the lower frame 14 and the upper frame 43 while being held in the upper holding groove portion 24.

  At the time of erection work, first, the panel unit 15 is moved from the front side between the lower frame 14 and the upper frame 43 in a state where the panel units 15 are inclined one by one in the direction toward the back side. . Then, the upper collar 26 is caused to enter the upper holding groove 24, and the panel unit 15 is oriented in the vertical direction while pushing the upper collar 26 to the back of the upper holding groove 24. As a result, in the state where the upper collar 26 has reached the inner end of the upper holding groove 24, the lower collar 27 is positioned directly above the lower holding groove 20, so that the panel unit 15 is lowered, The lower collar 27 is inserted into the lower holding groove 20. In this state, the upper edge of the panel unit 15 is held by the upper frame 43 and the lower edge of the panel unit 15 is held by the lower frame 14. Therefore, in this state, the lower frame 14 and the lower rod 27 are connected to the upper frame 43 and the upper rod 26 by the fixing screws 29 and 29 inserted through the lower frame 14 and the upper frame 43 from the back side. Are fixedly coupled to each other. As a result, the panel unit 15 cannot be removed from the surface side of the fence. When constructing a fence, these series of operations are performed for each panel unit 15. When any panel unit 15 is removed from between the upper frame 43 and the lower frame 14 for repair or the like, the above operation is performed in reverse order. In the case of the structure of this example, when a certain panel unit 15 is attached / detached, the other panel unit 15 is not inclined or detached, so that any work can be performed with a small number of people (minimum number of people). , Even one person is possible).

According to the structure of the present example configured as described above, the design is not easily affected by the interval (pitch) between the support columns 13, 13, and the construction work and the repair work can be performed by a small number of people.
First, each of the panel units 15 and 15 is provided between the upper frame 43 and the lower frame 14 provided between the support columns 13 and 13 so as to protrude to the front side of the support columns 13 and 13. Therefore, most of the columns 13, 13 are hidden behind the panel units 15, 15, and do not appear on the front side where the design is regarded as important. Therefore, when considering the design of the fence, it is not necessary to associate the width and pitch of the panel units 15 and 15 with the pitch of the support columns 13 and 13. As a result, the degree of freedom in design design is improved. For example, FIG. 4 shows a case where a design in which the saddle members 6 and 6 constituting the conventional structure shown in FIGS. 6 to 11 are installed between adjacent panel units 15 and 15 is configured. Yes. Even when such a design is constructed, even if the pitch of the columns 13 and 13 is left as they are, the design does not give a sense of incongruity.

[Second Example of Embodiment]
FIG. 5 shows a second example of an embodiment of the present invention corresponding to claims 1 and 3 . In the case of this example, the upper frame 30 is constituted by a coupling portion 31 and a headboard portion 32, both of which are made of an extruded material of an aluminum alloy. The coupling portion 31 includes a horizontal plate portion 33 and a rising plate portion 34 that is bent upward from the surface side of the fence (left side in FIG. 5) among both end edges of the horizontal plate portion 33. Of these, the horizontal plate portion 33 is coupled and fixed to the upper end portion of each column 13 by tapping screws 22 and 22. On the other hand, the cross section of the half portion on the surface side of the fence is configured so that the cap 32 can be engaged with and disengaged from the coupling 31 and is engaged (coupled) to form the upper frame 30. The bottom is open.

  In order to enable the coupling portion 31 and the headboard portion 32 to be engaged and disengaged, in the case of this example, a fixed side locking piece 35 bent to the surface side of the fence is provided at the upper end edge of the rising plate portion 34. Forming. On the other hand, a detachable side locking piece 36 is formed at the center of the lower surface of the headboard portion 32, and a screw receiving piece 37 is formed on the inner surface of the back side end portion (right end portion in FIG. 5) of the fence. When the coupling portion 31 and the headboard portion 32 are coupled, the fixed side locking piece 35 and the headboard portion 32 are displaced from the front surface side of the fence with respect to the coupling portion 31. The detachable side locking piece 36 is engaged, and the lower surface of the screw receiving piece 37 is brought into contact with the upper surface of the back side end portion of the coupling portion 31. Then, the screw 38 inserted through the lower end of the coupling portion 31 from below is screwed into the screw receiving piece 37 and further tightened.

  On the other hand, as in the case of the first example of the above-described embodiment, the lower frame 39 is supported and fixed to a portion near the lower end on the surface side of each column 13 via the mounting bracket 18. The shape of the lower frame 39 is slightly different from the first example of the above embodiment based on the difference in the coupling structure with each panel unit 15a described below. In particular, a horizontal plate portion 40 is provided at the upper end portion of the lower frame 39 and on the end portion on the side of each support column 13 for screwing a connecting screw with each panel unit 15a.

  Each panel unit 15a has an upper collar 26a and a lower collar 27a constituting both upper and lower edges thereof coupled and fixed to the upper frame 30 and the lower frame 39 by fixing screws 29a and 29a, respectively. ing. In this case, the detachable side collar 41 formed at the upper end on the back side of the upper collar 26a and the fixed side collar 42 formed at the middle part on the front surface side in the vertical direction of the rising plate 34 are engaged to The panel unit 15a is prevented from falling in a direction away from the columns 13 even before the fixing screw 29a is tightened.

  When constructing the structure of the present example as described above, the upper edge portion of each panel unit 15a is formed in the joint portion 31 in a state before the head portion 32 is joined and fixed to the joint portion 31. The upper collar 26a is fixedly coupled to the lower frame 39 with the lower collar 27a constituting the lower edge of each panel unit 15a. In this operation, first, each panel unit 15a is brought closer from the front side between the coupling portion 31 and the lower frame 39 in a state where each panel unit 15a is inclined in the direction toward the back side as it goes downward. Then, the lower collar 27a is caused to enter the lower holding groove 20a opened on the upper surface of the lower frame 39, and the panel unit 15a is moved in the vertical direction while pushing the lower collar 27a into the lower holding groove 20a. Turn to. Then, the panel unit 15a is lowered in a state where the detachable side collar 41 enters between the fixed side locking piece 35 and the fixed side collar 42.

As a result, the fixed side collar part 42 and the detachable side collar part 41 are engaged with each other, and at the same time, the lower surface of the front and rear side edges of the lower collar 27a and the upper surfaces of the horizontal plate parts 19 and 40 Are in contact with each other. In this state, the panel units 15 a are supported without falling between the coupling portion 31 and the lower frame 39 constituting the upper frame 30. Therefore, in this state, the fixing screw 29a inserted through the upper side of the upper side of the upper collar 26a from the front side is screwed into the rising plate portion 34 and further tightened, and the end of the lower side of the lower collar 27a is moved upward. The fixing screw 29a inserted through is screwed into the horizontal plate portion 40 and further tightened. Finally, the headboard portion 32 is coupled and fixed to the coupling portion 31 by engaging the fixing pieces 35 and 36 with each other, and screwing and tightening the screws 38. In this state, the upper edge of each panel unit 15a is covered with the headboard 32. In addition, these panel units 15a cannot be removed from the surface side of the fence. When constructing a fence, the above-described series of operations excluding the operation of attaching the cap 32 is performed for each panel unit 15a, and finally the cap 32 is mounted. Further, when removing any panel unit 15a from between the upper frame 30 and the lower frame 39 for repair or the like, the above operation is performed in reverse order after removing the headboard portion 32. Also in the case of the structure of this example, when one panel unit 15a is attached / detached, the other panel unit 15a is not tilted or detached, so that any work can be performed with a small number of people (at least Limited to one person). Even in the structure of this example, for example, the design as shown in FIG. 4 can be configured (the degree of freedom in design design is high).
