The frame body also has a panel fixed thereto.

Description

The present invention relates to a structure for mounting a panel such as a solar panel or an advertising panel, and more particularly to a structure of a slope installation type rack and its installation method.

  Various methods have been proposed for effectively using natural slopes or slopes (called slopes) formed by building residential land, roads, railways, dams, and the like. Since there is a risk of collapse on such slopes, measures for preventing collapse, such as a ground anchor method, a rock bolt method, and a slope spray method, must be taken unless the slope is gentle. However, many of these are not measures to prevent slope failure, but in reality, the only effective way to effectively use the slope is to improve aesthetics by applying vegetation. Not implemented.

  On the other hand, the inclination angle varies depending on the slope, but the slope facing south is often suitable for installing solar panels. Also, slopes often have a high appealing effect when advertising billboards are installed.

  For example, solar panels have recently become widespread in ordinary households and are expected to be useful energy supply means in the future. And since it is inevitably installed toward the sun, it is convenient if the slope can be used.

In addition, if an advertising panel can be installed on the slope, it can be installed in multiple stages other than the method of arranging a plurality of sheets in a horizontal direction. Combining this makes a very innovative advertising tool.

JP 2010-138630 A

However, as mentioned above, there are many measures to prevent collapse in general, but if heavy objects such as solar panels or advertising panels are installed there, this causes the slope There is a risk of collapse. For example, if two solar panels (modules) having a size of about 1.3 square meters are made into one array, the total weight per unit exceeds 70 kg. From the viewpoint of power generation capacity and effective use of slopes, solar panels should be installed as many as possible (if possible, so as to fill the entire slope). Installation on a slope may cause the slope to collapse.

  Accordingly, the present inventors have finally made the present invention as a result of intensive studies in view of the above-mentioned points. The feature of the present invention is that the structure of the slope mounting base is fixed to the rectangular outer frame. A frame body made of a crosspiece and a grout-type anchor bar inserted into an upper and lower through-hole formed in the crosspiece, and a panel is fixed to the frame body Or a ladder-shaped frame body in which a plurality of horizontal beam members are spanned over a plurality of vertical beam members, and a grout-type anchor bar inserted into the upper and lower through holes provided in the frame body. The panel is fixed to the frame body, and with respect to the installation method, a hole is made in the inside from the slope, and the grout is injected together with the insertion of the anchor bar. After curing It is an installation method of a slope installation stand that connects and fixes the end of an anchor bar to a frame body, and the frame body is composed of a combination of a rectangular outer frame and a crosspiece, or a combination of a vertical crosspiece and a horizontal crosspiece, The anchor bar is fixed to the frame body after being inserted into the upper and lower through holes provided in the frame body.

  That is, the present invention uses a “anchor construction” technique, which is one of the construction methods for suppressing slope failure, to install panels such as solar panels and advertisement panels, which are difficult to install by common sense, into slopes. It can be safely and securely installed on the top. This will open up a road for further effective use on slopes that were previously only used to raise the landscape by vegetation.

  Here, the “frame body” is composed of a rectangular outer frame and a crosspiece (the rectangle includes a square as a matter of course), or is composed only of a crosspiece (a plurality of vertical crosspieces and horizontal crosspieces are bridged) There are two types of things. In addition, the rectangular outer frame and crosspieces are divided into a rectangular outer frame with a crosspiece and a rectangular outer frame with a crosspiece. In the present invention, there are three types. The structure is proposed.

  In the case where a crosspiece is arranged inside a rectangular outer frame, the rectangular outer frame is the main component that touches the slope when the slope is installed (the crosspiece portion may also touch the slope). This structure is close to the bearing plate in the anchor work, has a high bearing effect, and can be expected to prevent slope collapse.

  In the case where a crosspiece is arranged at the bottom of the rectangular outer frame, it is the crosspiece that touches the slope when installing the slope, and the rectangular outer frame is separated from the slope, so there is some unevenness on the slope. However, it is possible to expect the effect that it is easy to install at the designed angle, that is, it is easy to reduce the leveling work.

  Furthermore, since it is easy to increase the separation distance from the slope by providing a spacer under the crosspiece, the leveling operation itself may be omitted in the case of a slope that is flat to some extent. In this case, the spacer may be fixed to the crosspiece, or a detachable structure may be adopted.

  In the case where a frame body is formed by integrating a plurality of vertical beam members and horizontal beam members without having a rectangular outer frame, an effect of facilitating panel arrangement can be expected.

  Although there is no particular limitation on the material of the frame body and the like, the frame body may play the role of a bearing plate in the “bearing type anchor” referred to as an anchor work, and accordingly, appropriate strength and area are required.

 A plurality of frame bodies may be connected in one row. As a form of connection, a single frame body may be connected via a separate connection tool, and among the rectangular outer frames constituting the frame body, the vertical outer frame portion is connected to be rotatable. A method may be used, or other methods may be used.

  In the case of a ladder structure that combines a vertical beam and a horizontal beam without a rectangular outer frame, the frame at the optimum position (usually the highest position) has the effect of simplifying the connecting work. Only the body is grouted (described later), and the lower frame body can be installed with an anchor bar without injection of cement milk or other grout, or the lower frame body can be used without an anchor bar. Can be used. As a result, the construction period and cost can be significantly reduced.

  There is no particular limitation on the structure of the crosspiece. In the case of a frame body having a rectangular outer frame, a cross-shaped structure having one vertical beam and one horizontal beam is generally used. However, if the size and weight of the panel to be installed are large, the number of the frames can be increased. good. Note that the “bar material” is usually arranged in the vertical and horizontal directions, but in the present invention, the concept of the bar material includes the one that connects the diagonal lines of the rectangular frame.

  The frame body is provided with upper and lower through holes. This through hole is for inserting the anchor bar. It is preferable that the structure is reinforced so that the strength is not lowered by providing the through hole. The position of the through hole is not particularly limited, but basically it is preferably on the longitudinal center line of the frame body in terms of balance, and particularly in the center of the frame body is preferable in terms of the bearing effect.

  The anchor bar inserted through the through-hole uses the one used in anchor work (ground anchor work or lock bottle work) that is one of the countermeasures against steep slope collapse. In the present specification, this is called a grout-type anchor bar. This involves injection of cement milk, cement mortar, or synthetic resin instead of this (referred to as “grouting” in the present specification), and a part or the whole of the anchor bar embedded in the ground by injection is used as a fixing body. Function.

  The diameter and length of this anchor bar are the natural characteristics such as the topography (gradient) of the slope to be installed, geology (soil and rock), weather (design temperature, design snowfall, design rainfall and design wind receiving), In addition, the present invention is not particularly limited because it is determined as appropriate according to the situation of the slope collapse prevention measures that have already been taken prior to the installation of the slope installation stand of the present invention.

  In addition, since the slope installation stand of the present invention itself uses the “anchor construction” technology, it seems that the slope collapse prevention function of a certain degree is naturally exhibited, but the object of the present invention using the grout type anchor bar is to It is to be held on the slope by itself (that is, not depending on other forces). In that sense, the strength required for the anchor bar portion in the case of anchor work is also necessary in the present invention. That is not to say. The same applies to the strength required for the grout to be injected.

  Moreover, although this invention utilizes an anchor construction technique, it is not an anchor construction itself. The anchor method is a construction method whose main purpose is to fix the mass or soft rock of the base rock surface layer at the interface (slip surface), and the presence of the mass and soft rock is essential. However, the purpose of the present invention is to safely and reliably install the panel on the slope, and the presence of a clot or the like is not a requirement. Accordingly, the present invention can be applied to a slope where the rock surface is exposed.

  A “panel” is fixed to the frame body. As long as the panel is a plate-like material, it can be used for any purpose. However, a solar panel is particularly preferable because it is installed on a slope and effectively uses the slope.

  In the photovoltaic power generation system, the phrase “panel” refers to “module” (a module in which a plurality of solar cells are arranged and protected with a resin or a reinforced panel to be specialized for outdoor use). In many cases, a plurality of modules connected in a line is called an “array”. In the present invention, “panel” means this “array” when referring to a solar panel.

  The panel may be fixed to the frame body. However, the panel may be pivotably mounted so that the panel can rotate with respect to the frame body, and the inclination from the horizontal plane may be freely changed.

  When the slope of the slope for installing the slope installation stand of the present invention is equal to the inclination angle of the solar panel, the installation angle of the stand is equal to the angle of the solar panel. However, when the slope of the slope and the slope angle of the solar panel to be installed are different, it is desirable to adjust this. In such a case, the array can be arranged on the frame (which is arranged along the slope) so that the angle can be changed. The angle changing mechanism in this case is not limited at all.

When the angle can be changed, it is easy to stand a vertical advertising panel on the slope. If there is a slope at the height to look up and there is a sign there, it is very easy to catch your eyes.

  In the gantry structure, the present invention provides a frame body composed of a rectangular outer frame and a crosspiece fixed to the frame, and a grout-type anchor bar inserted into the upper and lower through holes formed in the crosspiece. A ladder-shaped frame body in which a panel is fixed to the frame body, or a plurality of horizontal beam members spanning a plurality of vertical beam members, and the frame It is composed of a grout-type anchor bar that is inserted into the upper and lower through-holes provided in the body, the panel being fixed to the frame body, and the installation method from the slope to the inside A method of installing a slope mounting base in which a hole is made in the pier and a grout is injected at the same time as the insertion of an anchor bar, and the end portion of the anchor bar is connected and fixed to the frame body during or after curing. Is The anchor bar is fixed to the frame body after being inserted into the upper and lower through-holes provided in the frame body. The invention is characterized by points, and is an extremely advanced invention having the following effects.

(1) The gantry has a structure consisting of a rectangular outer frame and crosspieces, or a vertical crosspiece and horizontal crosspieces. There is no need.
(2) Since the gantry is fixed to the slope with a grout-type anchor bar, the risk of slope collapse does not increase even when a large number of solar panels are installed. On the contrary, it is reinforced and the risk is reduced.
(3) Effective use of slopes that have been less useful up to now can be achieved.
(4) Panels can be installed regardless of the geology and angle of the slope that is the installation surface.
(5) Installation is possible even from the shoulder (upper part of the slope).

  FIG. 1 shows an example of a slope installation base 1 (hereinafter referred to as the present invention base 1) according to the present invention. As is apparent from the figure, the frame 1 of the present invention includes a frame body 4 composed of a rectangular outer frame 2 and a cross-shaped crosspiece 3 disposed below the rectangular outer frame 2, and an anchor bar 5 separate from the frame body 4. It is comprised by these. In addition, although the panel 6 is installed in this invention mount frame 1, the drawing is abbreviate | omitted in this figure.

  The size of the rectangular frame 2 is 1680 mm long × 1882 mm wide. In this example, L-shaped stainless steel is used as the material, but aluminum or iron may be used. Since it is installed outdoors, when iron is used, it is preferable to apply a rust prevention treatment by painting or the like. The same applies to the members constituting the rectangular outer frame 2 or the metal fittings for connecting the rectangular outer frame 2 and the crosspiece 3, and those that are not easily corroded or rust-proof are used. The total weight of the rectangular frame 2 and the crosspiece 3 (that is, the weight of the frame body 4) is about 37 kg.

The crosspiece 3 has a thickness of about 50 mm and is arranged in a cross shape, and a through hole 31 is provided at an intersection of the cross. The place where the through hole 31 is installed is preferably closer to the center of the frame body 4 if the slope collapse suppression effect is important. On the other hand, when importance is attached to the stability of the gantry 1 according to the present invention, the through hole 31 is preferably provided above the position of the center of gravity of the frame body 4 so as not to be rotated by wind or other external force. In other words, the optimum position for the through hole 31 may be selected as appropriate.
In this example, the cross-shaped portion of the crosspiece 3 is in contact with the slope during installation, and the rectangular outer frame 2 is separated from the slope by the thickness of the crosspiece 3 (50 mm in this example). Become.

  The anchor bar 5 is a steel material that is inserted through a through hole 31 formed in the crosspiece 3 of the frame body 4, and in this example, a steel bar having a length of 3000 mm was used. This anchor bar 5 uses what is conventionally used for “anchor construction” which is a construction method for suppressing slope failure. In this example, deformed steel bar D19 (SD345) is used. This has an ultimate pull-out force of about 94.2 KN, and is a common steel bar in anchor work. Since there are various types of anchor bars depending on the grade of the slope or the soil quality, the appropriate selection is made according to the situation at the site.

  The anchor bar 5 is inserted into the through hole 31 and fixed to the crosspiece 3. This fixing is performed by a method in which a screw groove is provided in the end portion of the anchor bar 5 and the screw groove portion protruding from the through hole 31 is tightened with a nut 51 (actually, metal fittings such as washers and washers are also used for drawing. (Omitted). The nut 51 is exposed as it is in the example of FIG. 1, but is preferably covered with a bag cap 52 as shown in FIG. In this example, the nut 51 has a function of complementing the misalignment between the through-hole 31 and the anchor bar 5, but a normal nut may be used (not shown).

  As described above, the frame body 4 of this example is provided with the crosspiece 3 at the lower part of the rectangular outer frame 2, so when this is installed, the thickness of the crosspiece 3 from the slope (50 mm in this example) Will be separated. Moreover, since it is not a frame but a cross-shaped portion that contacts the slope, it can be installed without any trouble even if the slope is slightly undulated. For example, if a large piece of rock appears on the ground surface, and you only have to remove or cut this rock for complete leveling, you will need a piece of equipment. However, in the case of the present embodiment, even if there is a rock exposed portion, it can be installed without hindrance if its height is small. Moreover, if the spacer 32 is provided under the crosspiece 3, the whole crosspiece 3 will rise further and it can respond to a bigger undulation. An example is shown in FIG.

  FIG. 4 shows another example of the present invention relating to the frame body 4, and in this example, the crosspiece 3 is installed inside the rectangular outer frame 2. In the case of such a structure, since the slope is largely pressed, a bearing effect close to that of the bearing plate in the anchor work can be expected, and the slope collapse preventing effect is also great. Of course, the flatness of the slope is required as compared with the previous example, but if it is flat, the adhesion to the slope is high, and it can be said that the strength (particularly the strength against wind and load) is excellent.

  Next, FIG. 5 shows an example in which a plurality (three in the figure) of the frame bodies 4 are connected in the vertical direction. The continuous arrangement was performed by connecting each frame body 4 in a rotatable manner with a connecting metal fitting 7. The reason why the rotation is possible is to enable follow-up even if there is some undulations on the slope, but it is not necessary to be able to be actuated in the case of a slope that is originally flat, for example. If a predetermined number of frame bodies 4 are connected in advance by the connecting bracket 7, the installation work at the site becomes simple.

  When the frame body 4 is installed in such a manner, depending on the state of the slope (inclination angle, soil quality, etc.), grout such as cement milk is poured into the drilling holes for all anchor bars 5 Installation is possible without doing. Also in this example, grout such as cement milk is poured into the drilled hole only to the anchor bar 5 of the frame body 4 at the highest position on the slope, and the other frame body 4 simply attaches the anchor bar 5 to the earth. The structure is just inserted deep inside. Further, in this example, the length of the anchor bar 5 is drawn with the length of the anchor bar 5 attached to the grout being equal to the length of the anchor bar 5 that is not, but if the strength can be maintained, the anchor without the grout is attached. The bar 5 may be short (on the order of a float) or may be omitted. An example of this short anchor bar 5 is depicted in FIG.

6 (a) and 6 (b) show still another example of the present invention for the structure of the frame body 4. The frame body 4 in this example includes two vertical bars 33 and a large number (in the figure). Twelve horizontal crosspieces 34 are integrated together. That is, it does not have a member called the rectangular outer frame 2.
In this example, the panel 6 (not shown in FIG. 1 (a)) is fixed to a pair of crosspieces 34, and a structure in which five panels 6 can be installed on one frame 1 of the present invention. (That is, 2 × 5 = 10 are directly involved in fixing the panel 6 out of 12 in total). Since it is such a structure, it is suitable for installation of many panels.
Further, in this example, it is assumed that one anchor bar 5 is provided in each of the upper and lower portions, and the through-holes 31 for that purpose are one arranged on the further outside of the ten that are involved in fixing the panel 6. A fixing block 35 is provided in each gap portion. In this example, two anchor bars 5 are provided, but the lower anchor bar 5 may be omitted depending on the situation at the site (not shown).

Furthermore, regarding the structure of the vertical beam member 33, a structure as shown in FIG. 7 may be adopted.
That is, the vertical beam member 33 is divided into lengths slightly longer than the height of the individual panels 6 to be installed, and the separated vertical beam members (unit beam members) are opposed to each other. In this structure, the end portions are nested, and these are connected by the shaft pin 8. As a whole, the frame body 4 of this example has a ladder-like structure.

  The details of the method of installing the frame body 4 on the slope using the anchor bar 5 are not limited. However, grout injection is essential (in the case of a ladder, at least one location is essential). Therefore, a hole is drilled to a predetermined depth at the site where the slope is installed, a hose is inserted into this hole, a grout is inserted with the anchor bar 5 inserted into the hole, and anchors are secured with nuts 51 and other fixing brackets. Basically, the bar 5 and the frame body 4 are fastened together. Other methods may be used as long as grout can be injected into the hole.

  A panel 6 (sunlight panel) is installed on the frame body 4. An example of this panel 6 is shown in FIGS. Each panel 6 is an array composed of 5 × 10 modules 61, and two panels 6 are fixed on the crosspiece 3 of the frame body 4. Further, in the case of (a), the panel 6 is integrally fixed to the frame body 4, but in the case of (b), the panel 6 is rotatably attached to the frame body 4. Thereby, even if a slope is a gentle slope, the inclination of the panel 6 can be enlarged, and it can be made into the perpendicular direction depending on the case. The rotation mechanism is not limited to the illustrated example, and may be various.
