Description

  The invention according to the present application relates to a base member for a plate-like ridge.

  Conventionally, a fence has been installed at the boundary with a neighboring land such as a detached house or an apartment for the purpose of protecting the privacy by blocking the view from the neighbor. It is preferable not to provide a ventilation region (gap hole or the like) as much as possible as the rod used for such a purpose, and conventionally, a block rod formed simply by stacking hollow blocks has been used. However, in such a structure, the number of hollow blocks to be stacked increases as the height of the ridge increases. Therefore, the block fence has problems that increase the construction cost and prolong the construction period.

  Therefore, at present, for such a problem, for example, a plate-like ridge disclosed in Patent Document 1 has been used. The plate-shaped basket disclosed in Patent Document 1 is obtained by installing a panel body on a cubic concrete block for foundation. The foundation concrete block disclosed in Patent Document 1 has a height of 400 mm, a width of 1000 mm, a depth of 120 mm to 140 mm, a weight of 12 kg to 13 kg, and is lightweight and excellent in workability. It can be installed at low cost.

  However, if the concrete block for foundation disclosed in Patent Document 1 has a ventilation area (gap hole) as much as possible for the panel body to be installed in order to improve the blindness, a strong wind suddenly blows. At that time, a great load is applied to the panel body. For example, when the foundation concrete block is installed in an environment where wind pressure of wind speed of 30 to 38 m / s is applied, the concrete block part holding the panel body may be cracked and the panel body may not be held, The concrete block for foundation itself may fall over. Here, the influence of the wind can be reduced as the ratio of the above-described ventilation region provided in the panel body is increased. However, a complete blinding effect cannot be obtained unless the ratio of the ventilation region in the entire panel body is made as close as possible to 0%.

  In contrast to the above-described problem, Patent Document 2 discloses that a blindfold panel that does not break due to the influence of wind power is “between a plurality of rectifying plates that extend along the depth direction when the wind passage direction is the depth direction. 1st rectification | straightening which is a blindfold panel which has the several ventilation path formed, Comprising: Each rectification | straightening board inclines by the predetermined angle to one side of the depth direction on the basis of the top part located in the depth dimension of a blindfold panel And a second rectifying unit extending at a predetermined angle to the other side in the depth direction with the top as a reference, and the plurality of rectifying plates have a constant interval in a direction along a plane orthogonal to the depth direction. Are arranged on the imaginary line connecting the extended ends of the first rectifying unit and the second rectifying unit in the other adjacent rectifying plates, or on the other rectifying plate side adjacent to the virtual line. Adopt the configuration set to There has been disclosed. The blindfold panel disclosed in Patent Document 2 has a structure in which a ventilated path that is bent or curved so that the adjacent ground cannot be visually recognized is provided in a wide area, so that the influence of wind is reduced while sufficiently protecting privacy. Is possible. However, the blindfold panel disclosed in Patent Document 2 is difficult to cope with in a strong wind region where a strong wind with a wind speed of about 30 to 38 m / s is blown because the wind pressure applied to the current plate increases. Furthermore, the blindfold panel disclosed in Patent Document 2 has a complicated structure, which increases the number of parts and requires time and labor to assemble, resulting in an increase in product cost, which is not preferable from a cost standpoint. .

  The present invention has been made paying attention to these conventional problems, and even when a plate-shaped ridge that is closed and has no air permeability is installed, an environment in which wind with a wind speed of 30 to 38 m / s is blown. An object of the present invention is to provide a base member for plate-like ridges that does not fall over or break for a long time.

  Therefore, as a result of intensive studies, the inventors of the present invention have come up with the idea of solving the above-described problems by adopting the plate-shaped saddle foundation member described below.

  The base member for a plate-like scissors according to the present invention is a base member for the plate-like scissors that fixes the plate-like scissors in the vertical direction, and extends in the horizontal direction from the wall portion extending in the vertical direction and the lower end of the wall portion. The extending bottom plate portion is integrally formed in an L-shaped cross section, and the wall portion has a column mounting hole for inserting and holding a column extending from the lower end of the plate cage on the upper end surface, The extending length from the wall portion is 70 cm or more.

  As for the base member for plate-shaped eaves which concerns on this invention, it is preferable that the minimum thickness around the said support | pillar attachment hole is 4.5 cm or more.

  It is preferable that the base member for plate-like ridges according to the present invention is a concrete structure obtained by a precast method.

  Even if the plate-shaped saddle foundation member according to the present invention is installed with a plate-like saddle that is closed on the entire surface, it may fall over a long period of time in an environment where a wind with a wind speed of 30 to 38 m / s is blown. There is no damage. Therefore, the base member for plate-like scissors according to the present invention can be suitably used for the purpose of preventing wind damage (including salt damage) in addition to the purpose of protecting privacy in a strong wind region.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The plate-shaped ridge foundation member 1 according to the present invention is a plate-shaped ridge foundation member that fixes the plate-shaped ridge in the vertical direction. This base member 1 for plate-like ridges is formed by integrally forming a wall portion 3 extending in the vertical direction and a bottom plate portion 2 extending in the horizontal direction from the lower end of the wall portion 3 into an L-shaped cross section. is there. The base member 1 for a plate-like ridge according to the present invention has such a shape, so that it can stably stand on the ground without using separate foundation concrete, etc., and increase the efficiency of construction work. I can do it. At this time, the wall part 3 and the bottom board part 2 are not specifically limited regarding the shape, For example, it can be made into rectangular plate shape. Furthermore, since the base member 1 for plate-like ridges according to the present invention has an L-shaped cross section, by placing earth and sand on the bottom plate part 2 in the construction state, misalignment or overturning due to earth pressure Can be more effectively prevented.

  Here, it is preferable that the base member 1 for plate-like ridges according to the present invention is a concrete structure obtained by a precast method. The base member 1 for plate-like ridges according to the present invention is excellent in strength and durability by integrally forming the wall portion 3 and the bottom plate portion 2 by a precast method, and is strong against the plate-like ridge 50, for example. Even if a wind blows or a person leans on the plate-like ridge 50, it becomes difficult to break or fall. And the foundation member 1 for plate-like gutters according to the present invention is integrally formed by a precast method, so that there is no need for on-site concrete placing work or concrete curing period, and the construction work can be carried out efficiently and the weather. It is not influenced by. That is, the base member 1 for plate-like ridges according to the present invention is a concrete structure obtained by a precast method, and can be easily arranged using a small construction machine or the like. Since skilled workers and special equipment are not required, the construction period and construction cost are not increased.

  By the way, concrete hardens when cement and water in the cement paste, which is a binder, chemically react to form glassy crystals, and is strongly affected by temperature and humidity during the curing process. Therefore, it is important to consider these environmental conditions when manufacturing a concrete product excellent in quality and durability. In addition, in order to produce a concrete product with excellent quality, it is necessary to carefully perform operations such as tapping to increase the density of concrete near the upper surface where moisture has increased in the placing process, and in the curing process, In order to protect the surface from drying and freezing, it is necessary to block the outside air and prevent the lack of water necessary for cement hydration. If these steps are not performed carefully, the concrete product will be cracked and the strength and durability will be inferior. However, in this respect as well, the base member 1 for plate-like ridges according to the present invention is manufactured by a precast method. A series of operations up to the installation can always be performed under the same conditions, and high quality can be stably maintained.

  Furthermore, the base member 1 for plate-like ridges according to the present invention can be manufactured and stored in advance in a factory or the like by being manufactured by a precast method, and the labor of workers can be dispersed. Moreover, the base member 1 for plate-like ridges according to the present invention is for plate-type ridges by containing a reinforcing material such as plate-like or bar-like steel materials or synthetic resin fibers in the mold in the concrete placing step. The strength of the base member 1 can be improved and the durability can be further improved.

  And in the base member 1 for plate-like ridges according to the present invention, the wall 3 has a column attachment hole 5 for inserting and holding a column 51 extending from the lower end of the plate-like ridge 50 on the upper end surface. Since the plate-like ridge 50 fixed to the plate-like ridge base member 1 according to the present invention is composed of a closed surface, the effect of preventing privacy protection can be sufficiently obtained while being low-cost. preferable. Here, the plate-like ridge 50 can be formed of a closed surface by installing a single plate or a plurality of plates with almost no gap. That is, the closed surface means that the ratio of the through-holes (ventilation regions) such as the gap holes in the entire surface (the entire surface including the frame when the plate-shaped rod 50 has a frame) is 0. % Or infinitely close to 0%. The material of the plate-like ridge 50 is not particularly limited, and a material such as aluminum can be appropriately employed. Temporarily, since the plate-shaped reed 50 is made of frosted glass, light can be taken in appropriately while blocking transparency, so that there is no shortage of sunlight. In addition, the plate-like wall 50 is made of a material having excellent transparency such as glass, so that an outdoor air conditioner outdoor unit, etc., is secured while ensuring a seaside view in a house near the coast. It can also be used for the purpose of preventing salt damage caused by corrosion.

  And in the base member 1 for plate-like ridges according to the present invention, the bottom board part 2 has a length extending from the wall part 3 of 70 cm or more. The base member 1 for plate-like ridges according to the present invention has an extension length from the wall portion 3 of the bottom base portion 2 (see reference sign X in FIGS. 2 and 4) of 70 cm or more. Makes it possible to be more stable and independent. Moreover, the base member 1 for plate-like ridges according to the present invention is installed by performing embankment such as earth and sand on at least the bottom plate portion 2 because the extension length from the wall portion 3 of the bottom plate portion 2 is 70 cm or more. By doing so, it is possible to use the plate-like reed having the whole surface closed and having no air permeability for a long period of time without any trouble in an environment in which a wind having a wind speed of 30 to 38 m / s is blown. For example, when a plate-like paddle 50 is used that is closed on its entire surface and has no air permeability, and earth and sand are filled on the bottom board portion 2, the length from the ground surface to the upper end of the plate-like paddle 50 is If it is 180 cm, no problem will occur even if it is used for a long time in a strong wind region where a strong wind with a wind speed of 30 to 38 m / s blows. In the above, it has been described that the embankment is performed on the side on which the bottom plate portion 2 is extended (the portion indicated by the reference numeral 100 above the imaginary line L of the installation surface height of the base member for plate-like ridges in FIG. 5). This embankment can also be performed on the side where the bottom board portion 2 is not extended (a portion indicated by reference numeral 101 above the imaginary line L of the installation surface height of the plate-shaped ridge foundation member in FIG. 5). The height of the embankment at this time can be made different between the side on which the bottom plate part 2 is extended and the side on which the bottom plate part 2 is not extended.

  Here, since the base member 1 for plate-like eaves according to the present invention is excellent in earthquake resistance and the like, it is also installed as a retaining wall for preventing the collapse of the ground on the back side by installing it on a land having a step. It can be suitably used. As shown in FIGS. 1 to 5, a drainage hole 4 can be provided in the plate-shaped gutter base member 1 used as a retaining wall. In addition, although the thickness of the base part 2 of the base member 1 for plate-shaped gutters which concerns on this invention is shown uniformly in FIGS. 1-5, weight is reduced and the transportability and workability | operativity are aimed at. At the same time, in order to reduce the material cost and reduce the product cost, the bottom plate portion 2 can be inclined on the upper surface so that the thickness thereof decreases from the wall portion 3 side toward the end portion side.

  Moreover, as for the base member 1 for plate-shaped eaves which concerns on this invention, it is preferable that the minimum thickness around the support | pillar attachment hole 5 is 4.5 cm or more. The base member 1 for a plate-like ridge according to the present invention has a column attachment hole 5 formed on the upper end surface (the upper surface of the wall portion 3), and the lower end portion of the column 51 of the plate-like ridge 50 in the column attachment hole 5 It is the structure which attaches the plate-shaped cage | basket 50 by inserting. Here, the base member 1 for the plate-like scissors according to the present invention has an upper end when the minimum thickness around the column mounting hole 5 (see symbol Y in FIGS. 2 and 4) is less than 4.5 cm. The strength in the vicinity of the column mounting hole 5 is inferior, which is not preferable. If the minimum wall thickness around the pillar mounting hole 5 is less than 4.5cm, the plate-shaped bowl will be used when sudden wind blows 30-38m / s or an adult with a weight of about 60kg leans. There is a risk that the foundation member 1 will be damaged.

  Further, the base member 1 for plate-like ridges according to the present invention has a minimum thickness of 4.5 cm or more around the column mounting hole 5 so that it does not have air permeability and has a length in the height direction of 180 cm. Even if a plate-shaped ridge 50 of the degree is attached, it can be used without being damaged in a strong wind region. Since the plate-like kite 50 is closed and has no air permeability, it does not escape from strong winds and receives wind pressure. However, even if the plate-shaped scissors 50 having a height of about 180 cm is installed in the base member 1 for the plate-shaped scissors according to the present invention by setting the minimum thickness around the support column mounting hole 5 to 4.5 cm or more, It can be used without being damaged for a long time in a strong wind region where a strong wind with a wind speed of 30 to 38 m / s blows.

  In addition, although the support | pillar mounting hole 5 is formed in the taper shape, the base member 1 for plate-shaped eaves shown in FIGS. 3-5 is plate-shaped on an upper end surface by making the support | pillar mounting hole 5 into such a shape. It becomes possible to easily insert the column 51 of the rod 50. A gap formed after inserting the column 51 of the plate-like rod 50 into the column attachment hole 5 can be filled with mortar or the like to firmly fix the column 51 to the plate-like rod base member 1.

  As mentioned above, although the base member 1 for plate-like ridges according to the present invention has been described, the foundation member 1 for plate-like ridges according to the present invention is not limited to the type of cement to be used, for example, Portland cement ( JIS R 5210), mixed cement, or the like can be used, and the size and type of aggregate such as sand and gravel to be added to the cement can be selected depending on the application. Moreover, the base member 1 for plate-like ridges according to the present invention can be appropriately set with respect to the water cement ratio in consideration of the purpose of use and requirements for use of the product, and the concrete curing method is also particularly limited. For example, room temperature curing, pressure curing, autoclave curing, etc. can be employed. The base member 1 for plate-like ridges according to the present invention is made of high-strength concrete having high strength, and thus has superior durability.
