Description

The present invention relates to a fence structure, a fence material constituting the fence structure, and a method for constructing a fence using the fence material.

Conventionally, concrete block fences and wet concrete where concrete is cast on-site have been used as fences that are installed at the boundary between adjacent houses and the boundary between houses and roads to prevent others from entering and exiting and to block the view. Fences are often used. In recent years, dry concrete fences, in which precast concrete panels are manufactured at a factory and transported to the site for construction, have also been used.

However, since the concrete block wall is constructed by arranging reinforcing bars vertically and horizontally and stacking blocks while filling with mortar, it takes a lot of time and effort to work on site. Also, in the case of wet concrete fences, the site where the formwork is installed so as to sandwich the reinforcing bars after assembling the reinforcing bars vertically and horizontally, the concrete is poured into the formwork, and the concrete is hardened and dried before the formwork is removed. It took a lot of time and effort to work in. On the other hand, in the case of a dry concrete fence, although it is possible to save the time to harden and dry the concrete on site and shorten the construction period, it is large because it transports heavy precast concrete panels and constructs them on site. There was a problem that it required a large number of workers as well as a transport vehicle and a crane.

In addition, wet concrete fences that require large formwork and large precast concrete panels are used in places where large transport vehicles and cranes cannot enter, such as places where the surrounding road width is narrow or where the surplus site area is small. There was a problem that the dry concrete fence using the above could not be constructed.

Furthermore, in the case of concrete block walls and concrete walls, various standards such as the spacing between reinforcing bars, the height and thickness of the fence, and the depth of foundation penetration are required by law in order to maintain the prescribed strength to prevent collapse. However, there are a large number of old fences nationwide that do not meet the current standards. In recent years, due to the enormous damage caused by large-scale earthquakes, old fences that do not meet the current standards are required to be dismantled and removed and replaced with new fences. Due to the above-mentioned problems in the construction of fences, the fact is that the reconstruction of fences has not progressed. If a new fence can be constructed by reducing labor and time, even if the road width and site are narrow, it is considered that the rebuilding of the fence will be promoted.

On the other hand, metal or wooden fences (fences, board fences) can be constructed without much labor and time, even if the road width or site is narrow, but the fence feels profound. There is a circumstance that it is not liked by consumers who seek.

Therefore, in view of the above circumstances, the present invention can reduce labor and time to construct a fence structure even when the road width and the site are narrow, and provide a fence structure that gives a profound feeling. An object of the present invention is to provide a fence material to be constructed and a method for constructing a fence using the fence material.

In order to solve the above problems, the wall structure according to the present invention is
"Aluminum frame having a pair of upper and lower horizontal members and a pair of vertical members connecting the horizontal members, a pair of covering plate materials covering the openings of the frame from both sides, and a pair of the horizontal members. Multiple wall units that are wider than they are tall, with through holes that penetrate each material on the same axis.
In a state where each of the through holes is stacked on the foundation portion in the height direction so as to be on the coaxial line.
A long rod-shaped member having a male screw formed at least at the upper end is inserted into the through hole of each of the plurality of fence units.
The lower end of the long rod-shaped member is embedded in the foundation portion, and the female screw member is screwed into the male screw at the upper end of the long rod-shaped member, so that the plurality of fence units are formed in the foundation portion. It is "fixed".

The wall structure of this configuration can be constructed by the following construction method. That is,
"A foundation portion having a vertical hole is formed at a position corresponding to the through hole, and the base portion is formed.
After stacking a plurality of the fence units on the foundation portion in the height direction,
The long rod-shaped member is inserted into the through hole of each of the plurality of fence units from above the uppermost fence unit, and the lower end thereof is inserted into the vertical hole.
By embedding the lower end of the long rod-shaped member in the vertical hole, the long rod-shaped member is fixed to the base portion, and the female screw is attached to the male screw at the upper end of the long rod-shaped member from above the fence unit on the uppermost stage. It is a construction method of "screwing a screw member".

In the above, the "width" refers to the length in the direction in which the fence extends along the boundary between the two regions when the two regions are divided by the fence.

The fence structure of this configuration is constructed with the fence unit as a constituent unit, and the fence unit can be manufactured in advance at the factory. Further, since the plurality of fence units stacked in the height direction are fastened by the long rod-shaped member and the female screw member and fixed to the base portion, it is not necessary to fix the fence units to each other by welding or adhesion. Therefore, it is possible to construct a fence structure by reducing labor and time.

In addition, the fence unit has a hollow structure in which the frame is covered with a covering plate material from both sides, and the frame is made of aluminum and is lightweight, so depending on the size setting, one or two workers can manually carry it. It is possible. Therefore, even at a construction site where the road width and site area are narrow and large transport vehicles and cranes cannot enter, the fence structure can be constructed without any problem.

Further, although the fence unit constituting the fence structure is a hollow structure, it cannot be seen from the appearance that it is a hollow structure, and since it is thicker than the fence, it is possible to construct a fence that gives a profound feeling. In addition, since the fence unit, which is a constituent unit, has a width longer than the height, it gives a feeling of spreading in the lateral direction, resulting in a solid and solid fence structure.

Next, the "fence material" according to the present invention is
"Aluminum frame having a pair of upper and lower horizontal members and a pair of vertical members connecting the horizontal members, a pair of covering plate materials covering the openings of the frame from both sides, and a pair of the horizontal members. Multiple wall units that are longer than the height and have through holes that penetrate each material on the same axis.
A long rod-shaped member having a thickness longer than the total height of the plurality of fence units and being inserted into the through hole and having a male screw formed at least at the upper end.
It includes a female screw member to be screwed into the male screw. "

This is a fence material that constitutes the above-mentioned fence structure and is used in the above-mentioned method for constructing a fence. Further, the "fence material" according to the present invention has, in addition to the above configuration,
"The fence unit further has a positioning member attached to the outer surface of each of the pair of upper and lower cross members at the same position in the lateral width direction.
Each of the positioning members has a length in the depth direction equal to half the length in the depth direction of the cross member, and one of the upper and lower pairs of the cross members is positioned along the long side on the inner side in the depth direction. with member is attached, the other of the upper and lower pair of transverse members, wherein the positioning member is mounted along the front long side in the depth direction "Ru der ones.

Here, the "depth direction" refers to the direction connecting one area and the other area when the two areas are divided by a fence, in other words, the thickness direction of the fence.

In this configuration, when stacking a plurality of fence units in the height direction, the positioning member of the lower fence unit and the positioning member of the upper fence unit are brought into contact with each other to stack the plurality of fence units straight upward. Can be easily performed.

As described above, as an effect of the present invention, a fence structure that can be constructed even when the road width or the site is narrow by reducing labor and time, and a fence structure that gives a profound feeling, is configured. It is possible to provide a fence material to be used and a method for constructing a fence using the fence material.

Hereinafter, a fence structure according to an embodiment of the present invention, a fence material constituting the fence structure, and a method of constructing a fence using the fence material will be described with reference to FIGS. 1 to 7.

First, the fence material will be described mainly with reference to FIGS. 1 and 2. The fence material of the present embodiment includes a plurality of fence units 1, a long rod-shaped member 31, a female screw member 32, and a cover member 40.

The fence unit 1 includes a frame 10 having horizontal members 11a and 11b and vertical members 12, a pair of covering plate members 20 covering the openings of the frame 10 from both sides, and penetrations formed in the horizontal members 11a and 11b. The holes 15 and the positioning members 17a and 17b attached to the outer surfaces of the cross members 11a and 11b are mainly provided.

Specifically, as shown in FIG. 1, the frame 10 is composed of a pair of parallel horizontal members 11a and 11b at the top and bottom and a plurality of vertical members 12 connecting the pair of horizontal members 11a and 11b in the orthogonal direction. The horizontal members 11a and 11b and the vertical members 12 are made of aluminum. The cross members 11a and 11b are long members having a U-shaped cross section, the upper cross member 11a has a U-shaped opening facing downward, and the lower cross member 11b has a U-shaped opening facing upward. And are connected by a vertical member 12. In each of the cross members 11a and 11b, two ribs 11r parallel to the major axis direction protrude on the inner surface of the middle portion of the U-shape.

The vertical member 12 has a square tubular shape with a square cross section, and one side of the square has a length equal to the distance between one of the pair of side walls in the U shape of the horizontal members 11a and 11b and the rib 11r closer to the side wall. Is. Therefore, by fitting and welding the upper end and the lower end of the vertical member 12 between the side wall and the rib 11r in the U-shape of each of the upper and lower horizontal members 11a and 11b, two rows of vertical members 12 are formed in the depth direction. The cross members 11a and 11b can be connected by positioning. Here, a case where a pair of horizontal members 11a and 11b are connected by a total of 12 vertical members 12 in a total of 12 vertical members 12 in the width direction and 2 rows in the depth direction of the horizontal members 11a and 11b is illustrated.

A plurality of through holes 15 are formed in each of the pair of cross members 11a and 11b. The number of through holes 15 of the upper cross member 11a and the number of through holes 15 of the lower cross member 11b are the same, and they are on the coaxial line, that is, on a virtual straight line in the vertical direction. Further, the through hole 15 is formed in the horizontal members 11a and 11b at a position away from the portion where the vertical member 12 is connected. Here, a case where one cross member 11a, 11b has three through holes 15 is illustrated. The through hole 15 has a size through which the long rod-shaped member 31 passes.

The positioning members 17a and 17b are attached to the upper cross member 11a at a plurality of positions on the upper surface of the middle portion of the U-shape, and the positioning members 17a and 17b are attached to the lower surface of the middle portion of the U-shape with respect to the lower cross member 11b. It is attached in multiple places. Each of the positioning members 17a and 17b is a rectangular flat plate, and the length in the depth direction is equal to half the length in the depth direction of the cross members 11a and 11b. The positioning members 17a and 17b are attached along one of a pair of long sides in the middle portion of the U-shape of the cross members 11a and 11b. The long side along which the positioning member 17a attached to the upper cross member 11a is along and the long side along which the positioning member 17b attached to the lower cross member 11b is along are the cross members 11a and 11b. Sides on different sides in the depth direction of. For example, when the upper positioning member 17a is along the long side on the back side in the depth direction, the lower positioning member 17b is along the long side on the front side in the depth direction. Further, the upper positioning member 17a and the lower positioning member 17b are attached to the same position in the lateral width direction of the fence unit 1.

There is a pair of covering plate materials 20 for each frame 10, and they are attached from both sides of the frame 10, that is, from the back side and the front side in the depth direction. Each covering plate material 20 has a size that covers the entire frame 10 including the opening of the frame 10. The covering plate material 20 is supported on the side wall of the upper cross member 11a by the hook-shaped attachment 19a bent downward, and the lower cross member 11b is supported by the hook-shaped attachment 19b bent upward. It is supported by the side wall of. The upper attachment 19a protrudes from the spacer material 18 attached to the outer surface of the side wall of the upper cross member 11a. The spacer material 18 is for forming a ventilation space between the covering plate material 20 and the vertical material 12.

As the covering plate material 20, a ceramic-based, metal-based, or resin-based decorative plate can be used. Further, when finishing the appearance like a single wall surface, such as painting the entire wall surface of the wall surface after constructing the wall structure, a base plate can be used as the covering plate material 20. When covering both sides of the frame 10 with the covering plate material 20, the hollow space inside the frame 10 may be filled with a soundproofing material.

Here, the fence unit 1 is rectangular when viewed from the front, and its width is longer than its height. Specifically, the fence unit 1 of the present embodiment has a height of about 46 cm, a width of about 280 cm, and a length (thickness) of about 15 cm in the depth direction. For example, if the height is 30 cm to 60 cm, the width is 200 cm to 350 cm, and the length in the depth direction is 10 cm to 30 cm, one or two workers can manually carry one fence unit 1. Cheap.

The long rod-shaped member 31 may have a male screw formed at least at the upper end, but in the present embodiment, a bolt having a male screw formed over the entire length is used. This is a glass fiber reinforced plastic bolt that is sometimes used as a rock bolt in the mountain construction method, and has the advantages of high tensile strength, light weight, and no rust or corrosion. The long rod-shaped member 31 of the present embodiment is a bolt having a diameter of 32 mm, which is quite thick. On the other hand, the female screw member 32 has a screw groove on the inner peripheral surface for screwing with the male screw of the long rod-shaped member 31, and the outer peripheral surface is formed in a shape that meshes with the fastening tool.

The construction of the fence structure using the fence material having the above structure will be described mainly with reference to FIGS. 3 to 6. First, concrete is cast along the line for constructing the fence (the line that should be the boundary between the two areas) to form the foundation portion 50. At that time, by embedding the sleeve 51 in the base portion 50, a bottomed vertical hole 55 opened upward is formed in the base portion 50. The distance between the sleeves 51 (the distance between the vertical holes 55) is the same as the distance between the through holes 15 in the lateral width direction of the fence unit 1, and the size of the sleeve 51 (the size of the vertical holes 55) is such that the long rod-shaped member 31 can be inserted. The size.

After the foundation portion 50 is formed, the first-stage fence unit 1 is placed on the foundation portion 50. At this time, the position of the through hole 15 of the fence unit 1 is made to coincide with the position of the vertical hole 55 of the base portion 50. As the first-stage fence unit 1, a unit that does not have the lower positioning member 17b is used.

Next, the second-stage fence unit 1 is stacked on the first-stage fence unit 1. In the first-stage fence unit 1, the positioning member 17a is attached to the upper surface of the upper cross member 11a, and in the second-stage wall unit 1, the positioning member 17b is attached to the lower surface of the lower cross member 11b in the lateral width direction. It is installed in the same position. The lengths of the upper and lower positioning members 17a and 17b in the depth direction are half the lengths of the cross members 11a and 11b in the depth direction, and the lengths of the upper and lower positioning members 17a and 17b are different from each other with respect to the cross members 11a and 11b in the depth direction. It is attached along the long side. Therefore, as shown in FIGS. 4B and 4C, the lower fence unit 1 and the upper fence unit 1 are aligned in the horizontal width direction, and the upper and lower positioning members 17a and 17b are brought into contact with each other to bring the fences into contact with each other. Unit 1 can be stacked directly above.

Similarly, the fence units 1 are stacked in the height direction by the number corresponding to the desired height of the fence. Here, the case where three fence units 1 are stacked is illustrated. The uppermost fence unit 1 does not need the upper positioning member 17a, but there is no problem even if it has the upper positioning member 17a.

When a predetermined number of fence units 1 are stacked in the height direction, the through holes 15 of the fence units 1 and the vertical holes 55 of the foundation portion 50 are in communication with each other. Therefore, the long rod-shaped member 31 is inserted into the through hole 15 from above the uppermost fence unit 1, and the lower end of the long rod-shaped member 31 is inserted into the vertical hole 55 of the base portion 50. In this state, the vertical hole 55 is filled with concrete. The long rod-shaped member 31 is fixed to the foundation portion 50 by the hardened concrete filling layer 59. At the stage of performing this work, if the first-stage fence unit 1 is in a state before one of the pair of covering plate materials 20 is attached, the work of filling the vertical hole 55 of the foundation portion 50 with concrete is performed. , It can be performed through the hollow space inside the frame 10, and the work is easy. Similarly, the long rod-shaped member 31 is inserted into all the through holes 15 (here, three places) and fixed to the base portion 50.

The length of the long rod-shaped member 31 is based on the sum of the heights of a predetermined number of fence units 1 stacked in the height direction, the depth of the vertical holes 55 of the base portion 50, and the sum of the heights of the female screw members 32. , Set a little longer. Since the upper end of the long rod-shaped member 31 whose lower end is fixed to the base portion 50 protrudes above the uppermost fence unit 1, the female screw member 32 is fastened to the male screw of this portion. At that time, a washer-shaped flat plate may be interposed between the upper surface of the uppermost fence unit 1 (the upper surface of the upper cross member 11a) and the female screw member 32.

By tightening the female screw member 32 to the long rod-shaped member 31, a plurality of fence units 1 stacked in the height direction are fastened and firmly fixed to the base portion 50.

After tightening the female screw member 32 to all the long rod-shaped members 31, the cover member 40 is attached from above the uppermost fence unit 1. The cover member 40 is a long member having a cap-shaped cross section, and has the same length in the lateral width direction as the fence unit 1. On the upper surface of the uppermost fence unit 1, a plurality of intermediate members 47 are fixed at a position where the upper end of the long rod-shaped member 31 does not protrude, and then the cover member 40 is placed and fixed on the intermediate member 47. As a result, the long rod-shaped member 31 and the female screw member 32 protruding from the upper surface of the uppermost fence unit 1 are in a state of being shielded by the cover member 40, which improves the appearance and allows rainwater to enter the through hole 15. Inflow is prevented.

By the above work, the fence structure corresponding to the length of the fence unit 1 in the width direction is constructed. After that, by repeating the same work in the width direction, as shown in FIG. 7A, the fence units 1 are stacked in the height direction and the fence structure is continuously provided in the width direction. Will be built. In addition, a joint treatment may be performed in which a sealing material is filled between the fence unit 1 and the fence unit 1. When the covering plate material 20 is a base plate, finishing treatments such as coating, spray coating, and pasting of bricks and tiles are performed. As a result, it is possible to obtain a fence structure having an appearance of having a continuous single large wall surface while having a fence structure formed by a large number of fence units 1.

Further, as illustrated in FIG. 7B, by opening spaces in some places in the width direction of the fence structure, the fence structure can be made to have an appearance in which the planting P is a part of the fence. Alternatively, as illustrated in FIG. 7C, a columnar member 60 may be interposed between the fence structures in which the fence units 1 are stacked in the height direction. With such a structure, the planting P and the columnar member 60 become an accent of the fence structure, and while using the fence unit 1 whose length in the width direction is standardized, it is requested from the site area and the like. There is an advantage that it is easy to adjust the length of the fence structure in the width direction to match the length to be formed.

As described above, the fence structure of the present embodiment is constructed by stacking the fence units 1 in the height direction and connecting them in the width direction, and the fence unit 1 is manufactured in advance at the factory. be able to. Further, since the plurality of fence units 1 stacked in the height direction are fastened to the base portion 50 by being fastened by the long rod-shaped member 31 and the female screw member 32, the work of fixing the fence units 1 to each other is not required. Therefore, as compared with the conventional concrete block wall and wet concrete wall, the labor and time can be significantly reduced to construct the wall structure.

Further, the fence unit 1 has a hollow structure in which the frame 10 is covered with the covering plate material 20 from both sides, and the frame 10 is made of aluminum and is lightweight. In addition, depending on the size setting, one or two workers can perform it. It can be transported manually. Therefore, even at a construction site where the road width and site area are narrow and large transport vehicles and cranes cannot enter, the fence structure can be constructed without any problem.

Further, since the fence unit 1 is provided with a frame 10 having high mechanical strength in which the metal cross members 11 and 11b and the vertical members 12 are connected by welding, strong winds due to vibration due to an earthquake, a typhoon, or the like are provided. It is possible to construct a solid fence structure that does not deform or break even if it receives. In addition, in the present embodiment, the fence structure is extremely sturdy because three long rod-shaped members 31 having a diameter of 32 mm per length of about 280 cm in the width direction are passed through the three members.

In addition, since the frame 10 of the hollow structure fence unit 1 is made of aluminum and is extremely lightweight, damage can be kept small even if it collapses, and it can be easily removed and transported by hand. Can be done.

Further, although the fence unit 1 constituting the fence structure has a hollow structure, it cannot be seen from the appearance that it is a hollow structure, and the length (thickness) in the depth direction is larger than that of the fence, which gives a profound feeling. You can build a fence. In addition, since the fence unit, which is a constituent unit, has a width longer than the height, it has a fence structure that gives a feeling of spreading in the lateral direction and gives a solid and profound feeling.

Further, since the height of the fence can be changed depending on the number of fence units 1 stacked in the height direction, it is possible to construct a fence structure having a high degree of freedom in height.

Further, since the frame 10 is made of metal (aluminum), the nonflammable fence unit 1 can be obtained by using the covering plate material 20 as a ceramic or metal plate material. In this case, even in a fireproof area, a wall structure having a height of more than 2 m can be constructed.

Then, as the long rod-shaped member 31, a member made of a material that does not rust or corrode is used. In addition, by attaching the cover member 40 above the uppermost fence unit 1, rainwater is prevented from flowing into the through hole 15 through which the long rod-shaped member 31 is inserted. Therefore, the possibility that the wall structure will collapse or collapse due to the deterioration of the long rod-shaped member 31 over time is greatly reduced.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to the above embodiments, and as shown below, various improvements are made without departing from the gist of the present invention. And the design can be changed.

For example, the above settings such as the number of fence units 1 stacked in the height direction, the number of through holes 15 and the number of vertical members 12 per fence unit, and the like are merely examples. Further, in the above, the case where the vertical members 12 are provided in two rows in the depth direction of the frame 10 is illustrated, but the number of vertical members 12 may be one row or three or more rows. Further, as for the horizontal members, as long as one fence unit includes at least a pair of upper and lower horizontal members 11a and 11b, three or more horizontal members may be provided. In this case, the through hole 15 is provided so as to penetrate each of all the cross members on the coaxial line.
