Description

Article 30, Paragraph 2 of the Patent Act applies 24th "Earthquake Disaster Countermeasures Technology Exhibition" Yokohama - Natural Disaster Countermeasures Technology Exhibition -, February 6, 2020

The present invention relates to a fence structure and a fence material constituting the fence structure.

Concrete block walls and wet concrete walls, which are cast concrete on-site, have traditionally been used as walls to prevent people from entering and exiting, as well as to block the field of view, and are built at boundaries between adjacent homes and between homes and roads. Fences are often used. Furthermore, in recent years, dry concrete walls have been used in which precast concrete panels are manufactured in a factory and transported to the site for construction.

However, since concrete block walls are constructed by placing reinforcing bars vertically and horizontally and stacking blocks while filling them with mortar, it requires a great deal of time and effort on site. In addition, in the case of wet concrete walls, reinforcing bars are assembled vertically and horizontally, formwork is set up to sandwich the reinforcing bars, concrete is poured into the formwork, and the formwork is removed after the concrete has hardened and dried. The work required a great deal of time and effort. On the other hand, in the case of dry-type concrete walls, it is possible to shorten the construction period by eliminating the time required to harden and dry the concrete on site, but it is also possible to reduce the construction period by transporting heavy precast concrete panels and constructing them on site. There was a problem in that it required several transport vehicles and cranes, as well as a large number of workers.

In addition, in areas where large transport vehicles or cranes cannot enter, such as areas where surrounding roads are narrow or surplus site area is small, wet concrete walls that require large formwork or large precast concrete panels are installed. There was a problem that dry concrete walls using concrete could not be constructed.

Furthermore, in the case of concrete block walls and concrete walls, various standards such as the spacing of reinforcing bars, the height and thickness of the wall, and the depth of foundation penetration are stipulated by law in order to maintain a specified strength to prevent collapse. However, there are many old fences remaining across the country that do not meet the current standards. In recent years, due to the severe damage caused by a series of large-scale earthquakes, old fences that do not meet current standards are required to be dismantled or removed and replaced with new ones. Due to the problems mentioned above in the construction of fences, the reality is that no progress has been made in rebuilding the fences. If a new fence could be built with less labor and time, even when the road width or site is narrow, it would be possible to encourage the replacement of fences.

On the other hand, metal or wooden fences (mesh, fence, board fence) do not require much labor or time and can be constructed even when the road width or site is narrow. There is a reason that customers who want a solid feel do not like it.

Therefore, in the past, the present applicant has developed a fence structure that can be constructed with reduced labor and time even when the road width or site is narrow, and also gives a sense of solidity, and a fence for constructing the fence. We have proposed and implemented a new material (see Patent Document 1). This fence material consists of a fence panel unit in which the opening of an aluminum frame is covered with covering plates from both sides, and a through hole that passes through a pair of horizontal members that make up the frame. It is equipped with a long bar-shaped member. By stacking multiple fence panel units in the height direction so that the central axes of their respective through holes are on the same line, and burying the lower ends of the long rod-shaped members inserted into the through holes in the foundation, the fence structure is created. Constructed.

The fence material of Patent Document 1 has a hollow structure and is lightweight, and can be manufactured in advance at a factory and transported by a small number of workers, so there is no problem even if the construction site is small, saving labor and time. It is possible to construct a fence structure by reducing the Furthermore, since it is not obvious from the outside that the wall material has a hollow structure, it is possible to construct a wall structure that gives a sense of solidity.

The present invention was developed in the process of research to increase the variation of fence structures and fence materials based on the same concept, and based on the applicant's idea that fences should have fire resistance and higher mechanical strength. It was made by

JP2018-135703

As described above, the present invention can be constructed with reduced labor and time even when the road width or site is narrow, gives a sense of solidity, and has excellent fire resistance and mechanical strength. It is an object of the present invention to provide a high wall structure and a wall material constituting the wall structure.

In order to solve the above problems, the fence structure according to the present invention has the following features:
``A panel core material in which a cylindrical portion is joined to an aluminum honeycomb structure, and an aluminum covering plate material that covers at least the surface of the panel core material where the cells of the honeycomb structure are open. Multiple fence panel units are equipped with
stacked in the height direction on the base part so that the central axes of each of the cylinder parts are on the same line,
A long rod-shaped member having a male screw formed at least at an upper end is inserted into the cylinder portion of each of the plurality of fence panel units,
The lower end of the elongated rod-like member is buried in the foundation, and a female screw member is screwed into the male thread at the upper end of the elongated rod-like member, so that the plurality of fence panel units are embedded in the foundation. "is fixed to".

A "honeycomb structure" is a structure consisting of a large number of cylindrical cells partitioned by partition walls, and the shape of the cells can be polygonal, such as hexagonal, quadrangular, or triangular.

When constructing a wall structure with this configuration, first, the foundation is formed by pouring concrete, etc. At that time, a vertical hole is formed in the base portion at a position corresponding to the cylindrical portion of the fence panel unit. A plurality of fence panel units are stacked in the height direction on the base portion formed in this manner. At this time, the wall panel units are stacked so that the central axes of the cylindrical portions are on the same line. As a result, the cylindrical portions of each of the fence panel units communicate with each other.

A long rod-like member is inserted into the communicating cylinder section from above the uppermost wall panel unit to the lowermost wall panel unit, and its lower end is inserted and buried in the vertical hole of the base section. Then, the female screw member is screwed into the male screw at the upper end of the long rod-shaped member and tightened. As a result, the fence structure of this configuration is constructed in which a plurality of fence panel units are fixed to the base portion in a so-called "skewered" state by the long rod-shaped members.

The fence structure of this configuration is constructed using fence panel units as structural units, and the fence panel units can be manufactured in advance at a factory. In addition, multiple fence panel units stacked in the height direction are fastened to the foundation by long rod-shaped members and female screw members, so it is necessary to secure the fence panel units together by welding, gluing, etc. do not. Therefore, the fence structure can be constructed with reduced labor and time.

The honeycomb structure that constitutes the panel core material of the fence panel unit is a structure with many voids and is lightweight because it is made of aluminum. In addition, since the cylindrical portion that constitutes the panel core material together with the honeycomb structure has a hollow structure, it is lightweight. In addition, the covering plate material that covers at least the surface of the panel core material where the cells of the honeycomb structure are open is also made of aluminum. Therefore, since each fence panel unit is lightweight, it can be manually transported by one or two workers depending on the size setting. Therefore, even in construction sites where the road width or site area is narrow and large transport vehicles or cranes cannot access, it is possible to construct a fence structure without any problems. Furthermore, since each fence panel unit is lightweight, even if the fence collapses due to an earthquake or the like, damage can be kept to a minimum, and it can be easily removed and transported by hand.

In addition, when viewed from the side covered with the covering plate material, neither the honeycomb structure with many voids nor the hollow cylinder part is visible, and the thickness is greater than that of a net or fence, giving it a solid feel. You can build a fence that gives you.

In addition, since both the honeycomb structure and the covering plate material are made of aluminum, and aluminum is a material recognized as a noncombustible material, a noncombustible wall structure can be achieved. Previously, those skilled in the art did not have the attitude to make exteriors such as fences and gates nonflammable. On the other hand, the applicant believes that the exterior also needs to have a "disaster prevention" perspective, and believes that for disaster prevention, it is necessary to have not only earthquake resistance but also fire resistance. This method adopted the method of constructing the structure from noncombustible materials.

Furthermore, the panel core material of the fence panel unit has a honeycomb structure made of metal (made of aluminum). A honeycomb structure is a structure in which many partition walls are joined at many contact points, and has extremely high mechanical strength. Therefore, by having a metal honeycomb structure, it is possible to build a solid wall structure that will not deform or break even if it is violently vibrated due to an earthquake or exposed to strong winds such as a typhoon. can.

In addition to the above configuration, the fence structure according to the present invention has the following features:
"The cylindrical part has a square cylindrical outer cylinder and a cylindrical inner cylinder fixed to the inside of the outer cylinder,
The elongated rod-shaped member may be inserted into the inner cylinder.

In this configuration, the cylinder portion has a double structure of an outer cylinder and an inner cylinder, and the outer cylinder has a rectangular cylinder shape. Therefore, if the aluminum honeycomb structure is made into a rectangular parallelepiped, it will be easier to firmly connect it to the cylindrical part, and the shape of the panel core material consisting of the honeycomb structure and the cylindrical part will be suitable as the core material of the wall structure. Easy to arrange into a rectangular parallelepiped shape. In addition, a cylindrical inner tube is fixed inside the outer tube, and a long rod-like member is inserted through this inner tube, so the square tube-shaped outer tube can be sized to match the honeycomb structure. On the other hand, the cylindrical inner cylinder can be sized to match the length of the long rod-like member, thereby making it possible to reduce wobbling of the long rod-like member.

In addition to the above configuration, the fence structure according to the present invention has the following features:
"A joint layer made of an elastic material is formed between the plurality of wall panel units stacked in the height direction."

As the "elastic material" forming the joint layer, rubber or resin gel can be used. Here, as the "rubber", it is possible to use rubbers with high shock absorbing properties and vibration absorbing properties, such as urethane rubber and silicone rubber, which are generally referred to as "vibration isolating rubbers". "Resin gels" include isobutylene resin gels, urethane resin gels, silicone resin gels, styrene resin gels, etc., which are generally referred to as "earthquake resistant gels" and have excellent shock absorption and vibration absorption properties. A highly sticky resin gel can be used. In addition to a material that has already been gelled, the resin gel may be a fluid when filled between the fence panel units, and may be gelled afterwards to form a joint layer.

In this configuration, since a joint layer made of an elastic material is formed between the stacked fence panel units, the fence as a whole can be elastically deformed even if the fence panel units themselves are rigid bodies. This makes it possible to construct a wall structure with high vibration damping properties.

In addition, although gaps inevitably occur between the fence panel units, the formation of the joint layer eliminates these gaps, resulting in a wall structure that has water-stop properties. For example, even if the installation surface of the fence is submerged in water due to a flood, it is possible to reduce the risk that water will infiltrate into buildings such as houses surrounded by the fence.

Next, the "fence material" according to the present invention is
``A panel core material in which a cylindrical portion is joined to an aluminum honeycomb structure, and an aluminum covering plate material that covers at least the surface of the panel core material where the cells of the honeycomb structure are open. A plurality of fence panel units equipped with
a long rod-like member that is longer than the total height of the plurality of fence panel units, has a thickness that allows it to be inserted into the cylindrical portion, and has a male screw formed at at least one end;
a female screw member screwed into the male screw;
"It is equipped with the following."

This is the fence material used to construct the fence structure described above. By using the fence material of this configuration, it is possible to construct a fence structure that exhibits the above-mentioned effects.

As described above, the effects of the present invention are that even if the road width or site is narrow, it can be constructed with less labor and time, gives a sense of solidity, and has excellent fire resistance and mechanical strength. It is possible to provide a fence structure with a higher height and a fence material constituting the fence structure.

EMBODIMENT OF THE INVENTION Hereinafter, the fence structure which is a specific embodiment of this invention, and the fence material which comprises this fence structure are demonstrated using drawings.

First, the fence material will be explained mainly using FIGS. 1 and 2. The fence material of this embodiment includes a plurality of fence panel units 1, a long bar-shaped member 31, a female screw member 32, and a cover member 40. Here, the direction from one of the two regions partitioned by the fence to the other is referred to as the depth direction, and the length of each member constituting the fence panel unit 1 in the depth direction is referred to as "thickness." In addition, a direction perpendicular to both the depth direction and the height direction will be referred to as the width direction.

The fence panel unit 1 includes a panel core material and a covering board material. The panel core material includes a honeycomb structure 10 made of aluminum and a cylindrical portion 11 made of aluminum. In this embodiment, one panel core material includes three honeycomb structures 10 and two cylindrical portions 11. The honeycomb structure 10 is a rectangular parallelepiped. The cylindrical portion 11 has a double structure consisting of a rectangular outer tube 11a and a cylindrical inner tube 11b, and the thickness and height of the outer tube 11a are equal to the thickness and height of the honeycomb structure 10, respectively. The outer diameter of the inner cylinder 11b is slightly shorter than the widthwise length of the inner peripheral surface of the outer cylinder 11a, and the inner cylinder 11b is fixed to the inner peripheral surface of the outer cylinder 11a while being fitted into the center of the outer cylinder 11a. There is.

The two cylindrical portions 11 are each fixed to the honeycomb structure 10 while being sandwiched between the adjacent honeycomb structures 10. One panel core material formed by joining the honeycomb structure 10 and the cylindrical portion 11 is a rectangular parallelepiped in which the height is greater than the thickness and the length in the width direction is greater than the height. The honeycomb structure 10 is joined to the cylindrical portion 11 with the axial direction of the cells aligned with the depth direction.

The covering board material includes a pair of first covering board materials 21 each covering a pair of side surfaces where the cells of the honeycomb structure 10 are open in the panel core material, and a pair of first covering board materials 21 that respectively cover the pair of side surfaces where the cells of the honeycomb structure 10 are open in the panel core material. There are a pair of second covering plates 22 covering the side surfaces, respectively, and a pair of third covering members covering the upper and lower surfaces of the panel core material, respectively. The first covering plate material 21, the second covering plate material 22, and the third covering plate material 23 are all made of aluminum.

The third covering plate material 23 has a flat rectangular tube shape with an opening in the width direction and a low height, and its thickness and length in the width direction are equal to the thickness and length in the width direction of the panel core material, respectively. Screw receiving grooves 23g each having a C-shaped cross section and extending in the width direction are formed on the inner peripheral surface of the third covering plate material 23 on the front side and the rear side in the depth direction. A pair of third covering plates 23 are placed on an extension line of the central axis of the inner cylinder 11b, with one placed on the top surface of the panel core material and the other in contact with the bottom surface of the panel core material. , a circular hole 23b is provided therethrough.

The second covering plate material 22 is a rectangular flat plate, the length of one pair of sides is equal to the thickness of the panel core material, and the length of the other pair of sides is equal to the height of the panel core material and each of the pair of third covering board materials 23 is equal to the sum of the heights of With one of the pair of third covering plates 23 placed on the upper surface of the panel core material and the other in contact with the lower surface of the panel core material, each of the pair of second covering plates 22 is placed in the width direction of the panel core material. A pair of second covering plates 22 and a pair of third covering plates 23 are formed by driving screws that are brought into contact with the end faces of and passed through the second covering plate material 22 into the screw receiving grooves 23g of the third covering plate material 23. , and the panel core material are integrated.

The first covering plate material 21 is a rectangular flat plate, the length of one pair of sides is equal to the length in the width direction of the panel core material, and the length of the other pair of sides is the height of the panel core material and the length of the third covering board material 23 is equal to the sum of their respective heights. In the panel core material to which the pair of second covering board materials 22 and the pair of third covering board materials 23 are fastened, the first covering board material 21 is fixed to the front side and the rear side in the depth direction, respectively. be done.

As a result, the outer surface of the rectangular parallelepiped panel core material formed by joining the honeycomb structure 10 and the cylindrical portion 11 is covered with the first covering board material 21, the second covering board material 22, and the third covering board material 23. A fence panel unit 1 is formed. The fence panel unit 1 is lightweight because all of its constituent materials are made of aluminum. For example, if the size of the fence panel unit 1 is 30 cm to 60 cm in height, 150 cm to 350 cm in width, and 10 cm to 30 cm in thickness, one or two people can work on one wall panel unit 1. Easy to transport by hand.

Note that the outer surface of the first covering board 21 can be painted using a paint that is a certified fire-retardant material that does not reduce the fire-retardant performance of the first covering board 21 made of a noncombustible material.

The long rod-shaped member 31 only needs to have a male thread formed at least at its upper end, but in this embodiment, a bolt is used that has a male thread formed over its entire length. This bolt is made of glass fiber reinforced plastic and has the advantages of high tensile strength, light weight, and no rust or corrosion. The long rod-shaped member 31 of this embodiment is a fairly thick bolt with a diameter of 32 mm. The diameters of the hole 23b and the inner tube 11b in the fence panel unit 1 are each slightly larger than the diameter of the long rod-shaped member.

On the other hand, the female screw member 32 has a thread groove on its inner circumferential surface that engages with the male screw of the long rod-shaped member 31, and its outer circumferential surface is formed in a shape that engages with a fastening tool such as a wrench.

The cover member 40 is an elongated member having a U-shaped cross-sectional outline that opens downward, and the width of the opening is slightly larger than the thickness of the fence panel unit 1. In this embodiment, the cover member 40 is also made of aluminum.

Next, construction of the fence structure of the first embodiment using the fence material having the above configuration will be explained mainly using FIG. 3. First, concrete is poured along the line on which the fence is to be constructed (the line that should be the boundary line between the two areas) to form the foundation 90. At this time, by embedding a sleeve (not shown) in the base part 90, a bottomed vertical hole that opens upward is formed in the base part 90. The interval between the vertical holes is the same as the interval between the inner cylinders 11b in the width direction of the wall panel unit 1 (equal to the interval between the holes 23b), and the size of the vertical hole is large enough to allow the elongated rod-shaped member 31 to be inserted.

Once the base portion 90 is formed, the first stage fence panel unit 1 is placed on it. At this time, the positions of the inner tube 11b and hole 23b of the fence panel unit 1 are made to match the positions of the vertical holes of the base part 90.

On top of the first-stage fence panel unit 1, the second- and subsequent-stage fence panel units 1 are stacked until they reach the desired height as a fence. Here, the case where three fence panel units 1 are stacked is illustrated. In all the fence panel units 1 stacked in the height direction, the positions of the inner cylinders 11b and the holes 23b are matched.

When a predetermined number of fence panel units 1 are stacked in the height direction, the inner tubes 11b and holes 23b of all the fence panel units 1 are in communication with the vertical holes of the base 90. Therefore, the long rod-like member 31 is inserted into the hole 23b and the inner cylinder 11b from above the top wall panel unit 1, and the lower end of the long rod-like member 31 is inserted into the vertical hole of the base portion 90. In this state, the long rod-shaped member 31 is fixed to the foundation 90 by filling the vertical hole with concrete.

The length of the long rod-shaped member 31 is determined from the sum of the heights of a predetermined number of fence panel units 1 stacked in the height direction, the length buried in the base part 90, and the sum of the height of the female screw member 32. Set it to be slightly longer. The upper end of the elongated rod-shaped member 31 whose lower end is fixed to the base part 90 projects above the uppermost fence panel unit 1, so the female screw member 32 is fastened to the male screw of this part. At this time, a washer may be interposed between the upper surface of the uppermost wall panel unit 1 and the female screw member 32. By tightening the female screw member 32 to the long rod-shaped member 31, the plurality of fence panel units 1 stacked in the height direction are fastened and firmly fixed to the base portion 90.

After tightening the female screw members 32 to all the long rod-like members 31, the cover member 40 is attached from above the top wall panel unit 1. As a result, the elongated bar-shaped member 31 and the female screw member 32 protruding from the top surface of the uppermost wall panel unit 1 are shielded by the cover member 40, resulting in a good appearance and the holes 23b and internal threads. Rainwater is prevented from flowing into the tube 11b.

Through the operations described above, the fence structure of this embodiment is constructed by stacking the fence panel units 1 in the height direction and connecting them in the width direction. The fence panel unit 1 can be manufactured in advance at a factory. In addition, since the plurality of fence panel units 1 stacked in the height direction are fastened to the foundation 90 by the long bar-shaped members 31 and the female screw members 32, it is necessary to fix the fence panel units 1 to each other. do not. Therefore, compared to conventional concrete block walls and wet concrete walls, the wall structure can be constructed with significantly less labor and time.

In addition, the fence panel unit 1 is extremely lightweight because all of its constituent members are made of aluminum, and the panel core material is formed from a honeycomb structure 10 with many voids and a cylindrical portion 11 that is hollow. It is. By setting the above-mentioned size, it is possible for one or two workers to transport it manually. Therefore, even in construction sites where the road width or site area is narrow and large transport vehicles or cranes cannot access, it is possible to construct a fence structure without any problems. Furthermore, since each of the fence panel units 1 is lightweight, even if the fence collapses due to an earthquake or the like, damage can be kept to a minimum, and it can be easily removed and transported by hand.

Furthermore, the honeycomb structure 10, which is the structure of the panel core material, has many voids, so it greatly contributes to making the fence panel unit 1 lightweight. This structure resists stress acting from multiple directions and has extremely high mechanical strength. Therefore, it is possible to construct a strong wall structure that will not deform or break even if it is violently vibrated due to an earthquake or exposed to strong winds such as a typhoon.

Although the honeycomb structure 10 with many voids is used as the panel core material, the outer surface of the panel core material is covered with the first covering plate material 21 and the second covering plate material 22. Therefore, from the outside, it is indistinguishable from a solid fence structure, and since it is thicker than fences made of netting or fences, it is possible to construct a fence that gives a sense of solidity.

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

In addition, the constituent members of the fence panel unit 1 (honeycomb structure 10, cylinder part 11 (outer cylinder 11a and inner cylinder 11b), first covering board material 21, second covering board material 22, and third covering board material 23) Since everything is made of aluminum, it is possible to build a non-combustible fence structure.

Further, since the outer cylinder 11a of the cylinder part 11 has a rectangular cylinder shape and has the same thickness and height as the rectangular parallelepiped honeycomb structure 10, the workability of joining the cylinder part 11 and the honeycomb structure 10 is good. At the same time, the panel core material formed by joining the cylindrical portion 11 and the honeycomb structure 10 can be arranged into a clean rectangular parallelepiped with no irregularities on the outer surface.

Further, the cylindrical portion 11 has a cylindrical inner tube 11b, and the diameter of the inner tube 11b is set slightly larger than the diameter of the long rod-like member, so that the long rod-like member inserted through the inner tube 11b is It has the advantage of no rattling.

Next, the fence structure of the second embodiment will be described mainly using FIG. 4. The same components as those of the first embodiment will be denoted by the same reference numerals, and detailed explanation will be omitted. The wall structure of the second embodiment differs from the first embodiment in that a joint layer 52 is provided between the wall panel units 1 stacked in the height direction.

The joint layer 52 is formed of an elastic material such as rubber or resin gel. Here, a case where the joint layer 52 is formed of a sheet-like rubber 51 is illustrated as an example. The sheet-like rubber 51 can have the same length and thickness in the width direction as the fence panel unit 1, and can have a height of 5 mm to 20 mm. The sheet-like rubber 51 has a through-hole 51b formed in a position corresponding to the hole 23b of the fence panel unit 1 and the inner cylinder 11b, and is large enough to allow the elongated rod-shaped member 31 to be inserted therethrough.

When stacking a plurality of fence panel units 1 in the height direction, the rubber 51 is sandwiched between the fence panel units 1, and the lower end of the long rod-shaped member 31 inserted through the hole 23b, inner cylinder 11b, and through hole 51b is used as the base. By embedding it in the section 90, the fence structure of the second embodiment is constructed, which includes the joint layer 52 between the plurality of fence panel units 1 stacked in the height direction.

In the fence structure of the second embodiment, even if the fence panel unit 1 itself is a rigid body, the elasticity of the joint layer 52 allows the fence as a whole to be elastically deformed, making it possible to construct a fence structure with high vibration damping properties. . In particular, in this embodiment, the elongated rod-shaped member 31 is a bolt made of glass fiber reinforced plastic and is elastically deflectable, so that it can be elastically deformed so that the entire wall is deflected.

In addition, since the wall structure of the present embodiment includes the joint layer 52, there is no gap between the wall panel units 1 stacked in the height direction, so that the wall structure has water-stopping properties. Therefore, even if the installation surface of the fence is submerged in water due to a flood or the like, it is possible to reduce the risk of water infiltrating into buildings such as houses surrounded by the fence. In other words, the wall structure of the present embodiment is a highly disaster-prevention wall structure that not only has excellent vibration damping properties (earthquake resistance) and fire prevention properties, but also has water-stop properties.

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 can be made without departing from the gist of the present invention. and design changes are possible.

For example, the number of wall panel units 1 stacked in the height direction, and the number of honeycomb structures 10 and cylindrical portions 11 per wall panel unit 1 are not limited to the above numbers.

Furthermore, in the above example, a case where a sheet-like elastic material (rubber 51) is sandwiched between the fence panel units laminated in the height direction to form the joint layer 52 is illustrated, but the joint layer 52 is formed between the fence panel units 1. The joint layer 52 made of resin gel can be formed by filling the resin with the desired properties and then gelling it.
