Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an improvement in a connecting tool constituting a collapsing prevention/drainage frame for sloped surfaces, which are often found in cut-throughs for railways, roads, etc., and in residential development sites.

(Background Art) In order to prevent sloped surfaces found in cut-outs and the like from collapsing due to rain or the like after construction, it is widely practiced to protect the surface by covering the surface with grass or the like. At the same time, a framework is installed on the surface of the slope to protect the slope until grass or the like grows and to function as a reinforcing frame even after the grass grows.

Such a framework is made of, for example, a member 1 made of synthetic resin or metal and having a substantially H-shaped cross section as shown in FIG.
1, a large number of the members 1 and 1 are connected with bolts and nuts, and a grid-like framework as shown in FIG. 2 is constructed on an inclined surface to suppress the surface of the inclined surface.

However, when preventing the slope from collapsing using such a conventional framework, the following problems occur. In other words, since such a framework is simply fixed to the surface of a slope and presses down on the surface, it is not possible to drain away the moisture that accumulates within the slope after rain, and it is not effective in preventing collapse. Can not do it. In addition, to prevent the framework from floating up from the slope, the intersection part of the framework (section a in Figure 2) is fixed to the slope using wooden stakes, U-shaped metal rods, etc. This is the part where rainwater that falls on the slope is guided by the framework and accumulates most easily, so the wooden stakes and U-shaped metal rods mentioned above are susceptible to corrosion, and when they corrode, the framework gradually floats onto the slope. This results in an unstable situation where the object simply rests on the slope. Furthermore, since the framework is visible on the ground surface, even when grass, etc. grows on a slope, the grass will grow avoiding the framework,
The presence of the framework can be seen when viewed from a distance, giving the slope an artificial appearance, which is undesirable under special conditions such as natural parks, as it spoils the aesthetics.

In order to eliminate such inconveniences, the present inventor first connected a large number of main frame members each having a fixed length with vertical walls on the upper surface of the main part having a rectangular cross section in a diagonal lattice shape using first connectors. The first connector has a flow path that introduces moisture that has flowed down the side surface of the main frame material into the inside, and the second connector that is connected to the lower end of the main frame material at the lowest end has a flow path that introduces moisture that has flowed down inside this main frame material. He invented a collapsing and drainage frame for sloped surfaces that has an opening for discharging water to the outside of the sloped surface (Japanese Patent Application Laid-open No. 77505/1983).

First, to explain in detail the anti-collapse and drainage frame of the earlier invention, Figures 3 and 4 show that it is used in the frame of the earlier invention to prevent collapse of a sloped surface and also to drain water from the surface layer of the surface. The main frame material 2 is shown. The main frame material 2 has a vertical wall 4 formed on the upper surface of a main part 3 having a rectangular cross section, and a partition wall 5 is formed inside the main part 3 to partition the inside of the main part 3 into upper and lower parts for reinforcement. . Both ends of the standing wall 4 formed on the upper surface of the main part 3 are slightly cut off so that both ends of the main part 3 can be inserted into a connector to be described later.

In the collapse prevention/drainage frame body according to the previous invention, the main frame member 2 formed in this manner is as shown in FIG.
A large number of connecting devices 6 to 11 are connected in a diagonal grid pattern, and the vertical wall 4 is buried in the surface layer of the slope so that the upper surface of the vertical wall 4 substantially coincides with the ground surface. After rain, the moisture that accumulates inside the slope is guided by the upper side of the main frame members 2, 2 (the side located above the slope) and flows toward the connecting part of each main frame member 2, 2. , flows into the main part 3 from this connecting part, flows inside this main part 3, and is discharged to the outside of the inclined surface. For this reason, the main frame material 2,
The connecting tool installed at the place where the moisture guided on the upper side of 2 gathers has the function of connecting the main parts 3 of the main frame members 2, 2, and also draws the moisture contained in the surrounding soil inside. It also has a water capture function.

That is, the first connector 6 that connects the main frame members 2, 2 disposed diagonally in an X-shape has a main part 12 as shown in FIGS. 6 to 9 and a main part 12 as shown in FIGS. 10 to 12. It consists of a lid body 13 like this. A cylindrical portion 15 is formed in the center of a substrate 14 constituting the main portion 12, and extends through the substrate 14 in the vertical direction. A plurality of vertical walls 16, 17, and 18 are formed on the outer peripheral edge of the substrate 14 at intervals, and the main portion 3 of the main frame member 2 described above can be inserted between each vertical wall. It's summery. That is, a first chevron-shaped vertical wall 16 is placed on the lower edge of the substrate 14 (the top and bottom are as shown in FIG. 7), and a second chevron-shaped vertical wall 1 is placed on both left and right edges.
7 and 17, respectively, and the first and second standing walls 1
The space between 6 and 17 is defined as insertion portions 19 and 19 into which the main portion 3 is inserted. Further, third standing walls 18, 18 parallel to the second standing walls 17, 17 are formed on both left and right parts of the upper part of the substrate 14, and the main part 3 is also formed between the second and third standing walls. Insertion part 1 for insertion

A plurality of square pillars 21, 21 are formed between 8 and 18 symmetrically with respect to a vertical wall 20 at the center of the upper edge, and a curved flow path is provided between the compatible walls 18, 18. . On the other hand, as shown in FIGS. 10 to 12, the lid body 13 attached to the main part 12 has first to third parts spaced apart from each other at the upper, lower, left, and right edges of the substrate 22. Hanging walls 23, 24, and 25 are formed. Each of the hanging walls 23, 24, 25 is fitted onto the upper end of the vertical walls 16, 17, 18 of the main portion 12, and is formed lower than the vertical walls 16, 17, 18. Further, an X-shaped vertical wall 26 is formed on the upper surface of the base plate 14 of the lid body 13, and a column 27 is suspended from the lower surface. Top standing wall 26
The pillars 27 on the lower surface align with the vertical walls 4, 4 on the upper surface of the main frame member 2 connected to the first connector 6 and serve to connect these vertical walls 4, 4, and the support columns 27 on the lower surface have their upper surfaces connected to the main part 1.
When the first connector 6 is buried in the ground by contacting the lower edge of the vertical wall 20 at the center of the upper part of the main part 12, the vertical wall 20 is bent by the earth pressure, and the bend provided at the upper part of the main part 12 is bent. This prevents the flow path from being blocked. By the first connector 6 consisting of the main portion 12 and the lid body 13 formed in this way. The main frame material 2 shown in Figures 3 and 4,

Next, as shown in FIG. 5, a large number of main frame members 2, 2
The main frame members 2, 2 arranged horizontally and the lower ends of the main frame members 2, 2 arranged at an angle are connected to form the lower side of the drainage frame body 28, which is formed by connecting the main frame members 2, 2 in a diagonal grid pattern. The second connector 7 used for the part (c part in Figure 5) has a main part 29 as shown in Figures 13-14.
and a lid body 30 as shown in FIGS. 15-16 are combined to form a structure as shown in FIGS. 17-18. The main portion 29 is formed symmetrically as shown in FIG. 13, and has standing walls 3 formed parallel to each other at intervals in the horizontal direction of the drawing on the upper surface of the substrate 31.
The first insertion portions 34, 34 for inserting the ends of the main frame members 2, 2 horizontally arranged between the substrate 31 Second insertion portions 37, 37 are provided on the upper surface for inserting the lower end portions of the main frame members 2, 2, which are arranged in an inclined direction between the vertical walls 35, 36 formed parallel to each other and spaced apart, respectively. It is set up. Protrusions 38 and 39 are formed at slightly different positions on opposing side surfaces of a horizontal standing wall 32 and an inclined standing wall 35 formed adjacent to the top surface of the substrate 31, and between the compatible walls 32 and 35. It forms a curved flow path.
A spacer 40 is inserted between the compatible walls 32 and 35, and prevents the bent flow path from being blocked by the vertical walls 32 and 35 being bent. In addition, the vertical walls 36, 36 formed near the top center
A plurality of standing pillars 41, 42 are formed between them, and a curved flow path is formed between these standing pillars 41, 42 and protrusions 43, 43 formed on the upper surfaces of the standing walls 36, 36. There is. Furthermore, weir plate portions 44, 44 that do not reach the opposing vertical walls 32, 32 are provided on the upper surfaces of the ends of the vertical walls 33, 33 closest to the center.
A U-groove portion 45 is provided extending downward from between the two weir plate portions 44, 44. The bottom surface of this U-groove portion 45 is inclined upwardly with respect to the top surface of the substrate 31. In the center part of the board 31, like the main part 12 of the first connector 6 described above,
A circular tube portion 46 is formed to vertically penetrate this substrate 31. On the other hand, the lid 30 attached to the main portion 29 is attached to the main portion 29 as shown in FIGS.
A base plate 50 consisting of the lid body 30 and the main portion 29 is mounted on the upper surface of the base plate 50, which has hanging walls 47, 48, 49 formed on the edge portions, which fit around the upper edge portions of the vertical walls 32, 33, 35, 36. A standing wall 51 is formed that aligns with the standing walls 4, 4 on the upper surfaces of the main frame members 2, 2 connected to the two connectors. Furthermore, a cover piece 52 having an arc-shaped cross section and covering the upper side of the U-groove portion 45 of the main portion 29 is formed at the lower end edge of the lower hanging wall 47 . Also,
The central part of the lower surface of the board 50 is in contact with the lower side of the upper end of the vertical column 41 at the center of the upper edge of the main part 29, and this vertical column 4
A strut 53 is formed to prevent deformation of 1.
The second connector 7 consisting of the main portion 29 and the lid 30 formed in this way is assembled as shown in FIGS. 17 and 18, but in order to connect the main frame members 2, It is only necessary to insert the ends of the main frame members 2, 2 into the four insertion parts 34, 37 of the main part 29 and cover them with the lid 30 from above.

Next, as shown in parts d and e in FIG. Connector 8,
8 can be used exactly the same as the second connector 7 described above by simply changing the direction. That is,
Rotate the second connector 7 clockwise 90 degrees from the direction shown in Figure 13.
If it is rotated 90 degrees, it can be used as the connector for section d in Figure 5, and if it is rotated 90 degrees counterclockwise, it can be used as the connector for section e in Figure 5. can. However, in this case, the U groove part 45 of the main part 29 and the cover piece 5 of the lid body 30
the end opening 54 of the tubular passageway formed between the
(Fig. 18) is closed. In this case, moisture flowing down the main frame member 2 in the vertical direction does not flow into the U-groove portion 45 because of the weir plate portion 44. However, if the third connector 8 is not shared with the second connector 7 but has a separate shape, the main part 55 as shown in FIGS. The third connector 8 can also be formed by attaching a lid 56.

Next, as shown in part f in Fig. 5, the drainage frame 28
The fourth connector 9 that connects the upper end parts of the main frame members 2, 2 at the upper end parts is, as shown in FIGS. 23 to 25,
Insertion parts 58, 58 into which the main part 3 of the main frame member 2 is inserted are formed substantially perpendicularly to the upper surface of the circular tube part 57. This fourth connector 9 is simply the main frame member 2,
Since the upper end of 2 is only locked, a lid is not necessary.

Furthermore, the fifth connector 10 used at both corners of the upper end in FIG. It has the same structure as the fourth connector 9. Further, the sixth connector 11 used at both corners of the lower end in FIG. 5 can be configured in substantially the same manner as the second connector 7 by making the insertion portions have different angles.

Next, to construct the drainage frame 28 as shown in FIG. 5 by joining the large number of main frame members 2, 2 configured as described above and the first to sixth connectors 6 to 11, , a large number of first connectors 6, 6 on the inclined surface, the main part 1
The water catching part 2 (the part of the curved flow path made up of the square pillars 21, 21) is positioned above the slope and fixed by a stake passing through the circular pipe part 15 of the main part 12, The main frame members 2, 2 are stretched between the connectors 6, 6. In addition, a first
The second connector 7 as shown in FIGS.
The ends of the main frame member 2 are inserted into the second insertion portions 34 and 37. The opening 54 of this second connector 7 is connected to the drain frame 28.
When the entire structure is buried on a slope, the water can be taken directly out of the slope, or the end of another pipe can be connected to this opening 54, and the incoming water sent to the second connector 7 through this pipe can be drained directly to the outside of the slope. Make sure to drain off the slope. Furthermore, the third connector 8 is similarly fixed to the left and right sides of the drainage frame 28 with stakes, and the ends of the main frame member 2 are inserted. Additionally, a fourth connector 9 is provided on the upper side of the drain frame 28.
are fixed with stakes to lock the upper end of the main frame material 2. Furthermore, the four corners of the drainage frame 28 are also provided with the fifth and fourth corners as described above.
Either it is connected to the sixth connectors 10 and 11, or the end opening of the main frame member 2 is closed without providing any connectors.
Once the drainage frame 28 has been fixed to the upper surface of the slope in this way, furthermore, on top of this drainage frame 28,
The entire drainage frame 28 is buried in the surface layer of the slope by covering it with soil until the upper end surface of the vertical wall 4 of the main frame material 2 is flush with the ground surface.

When the collapse prevention/drainage frame for sloped surfaces of the previous invention in which each component is joined in this way is buried in the surface layer of the slope, some of the moisture contained in the ground is present in the surface layer of the slope. The material flowing down flows down along the upper side of the main frame member 2 and reaches the connecting portion between the main frame members 2, 2. As mentioned above, the first to third connectors 6 to 8 that connect the main frame members 2 and 2 have curved flow paths that take moisture flowing from above into the main frame members. The moisture flowing down the upper surface of the frame material 2 enters into the first to third connectors 6 and 8, and further flows into the inside of the main part 3 of another main frame material 2, and the moisture flows down the upper surface of the main frame material 2. It flows further down the inside. This moisture is collected by a large number of connectors 6 that constitute the drainage frame 28,
This is done every 7 and 8 times, and the collected moisture is transferred to the main frame material 2.
The liquid is collected in the main part 3 and discharged out of the inclined surface through the opening 54 of the second connector 7 located at the bottom.

The anti-collapse/drainage frame for sloped surfaces according to the previous invention is configured and operates as described above, so that moisture accumulated within the sloped surface due to rainfall can be efficiently drained, and the main frame material 2, 2 partitions the surface surface into a diagonal lattice pattern, which has a great effect in preventing collapse, and what is visible on the surface of the slope is the upper end of the vertical wall between the narrow main frame material and each connector. Because it is only a slope, the existence of the drainage frame becomes invisible after grass grows on the slope, and it has various excellent effects such as not spoiling the beauty of natural parks etc. During construction, the following troubles occur during construction.

That is, when burying each of the first to third connectors 6, 7, and 8 having a water-capturing function, each of the connectors 6, 7, and 8, which has a curved flow path formed by an upright pillar or protrusion, is buried. In order to prevent the water area from becoming clogged with sediment, crushed stone must be placed around this water catchment area. However, soil must be added to the areas outside the water-catching area to help the grass grown on the surface grow, making the work of burying the collapse-prevention/drainage frame tedious.

(Object of the present invention) In order to solve the above-mentioned disadvantages, the present invention
To provide a connecting tool that does not cause clogging even when soil is thrown around a water catching part and enables efficient work of burying a collapse prevention/drainage frame body.

(Structure of the present invention) The collapsing prevention/drainage frame connector on an inclined surface of the present invention includes a plurality of insertion portions into which the ends of the main frame material constituting the frame can be inserted, and a plurality of insertion portions. It consists of a main part provided with a water catching part that allows communication between the inside and the outside, and a lid that covers this main part, and the water catching part of the main part is filled with a filter material.

(Action of the present invention) The collapsing prevention/drainage frame connector for sloped surfaces of the present invention configured as described above has a structure that connects to the outer surface of the main frame material as in the case of the connector according to the previous invention. The water that flows down along the line is introduced inside through the water catchment part and flows into the inside of another main frame material, but it will not get clogged even if you put regular soil around the water catchment part.

(Embodiments of the present invention) Next, the present invention will be explained in more detail while explaining the illustrated embodiments.

Figures 26 and 27 show the present invention applied to a first connector for connecting main frame members in an X-shape. It is a bottom view. Similar to the main body of the first connector in the previous invention shown in FIGS. 6 to 9, a first chevron-shaped vertical wall 16 is provided on the lower edge of the substrate 14, and a second chevron-shaped vertical wall 17 is provided on both left and right edges. 17 respectively, and a main frame material 2 is formed between the first and second vertical walls 16 and 17.
The second standing wall 1 is provided on both the left and right parts of the upper part of the board 14.
Third standing wall 18, 18 formed parallel to 7, 17
A similar insertion portion 1 is also provided between the and second standing walls 17, 17
In the main part 3 with 9 and 19, the third standing wall 1
A water catching portion 59 provided between 8 and 18 is filled with a coarse fibrous filter material 60. That is,
A plurality of pillars 61, 61 having a triangular cross section are formed at intervals at the upper edge of the flat plate portion located between the third standing walls 18, 18.
A sheet-shaped filter material 60 is filled in a space surrounded by the filter material 61 and the third vertical walls 18, 18 in a rounded manner. 62 is this filter material 60
The filter material 60 is a column located inside the column, and the filter material 60 is
This filter material 60 is supported so that it is not crushed. In addition, 63 is the third standing wall 18, 1 on the left and right.
8 supports the filter material 60 so that it does not slip out downward from between the third vertical walls 18, 18.

Since the collapsing prevention/drainage frame connector for sloped surfaces of the present invention is constructed as described above, if it is to be buried underground, special crushed stone should be placed around the water catchment portion 59. Even if you do not add soil, this water will not enter the inside of the connector just by adding soil.
Moisture that collects in the vicinity of can also be effectively collected through the filter material 60. In the illustrated embodiment, a plurality of through holes 64, 64 are formed in the portion of the substrate covered with the filter material 60. The through holes 64, 64 serve to introduce moisture that has not been completely captured by the water capturing portion 59 and has entered the lower side of the connector into the inner side of the connector.

(Effects of the present invention) Since the collapsing prevention/drainage frame connector on a slope according to the present invention is configured and used as described above, the area around the water catching part of the connector when buried on a slope is Burying work can be carried out efficiently without the hassle of putting crushed stone only in the ground.

(Application example) In the above-mentioned embodiment, an example was described in which a filter material was provided in the water catching part of the first connector 6 that connects the main frame material in an X shape, but the present invention This method is applied not only to the first connector 6 but also to the other second and third connectors 7 and 8 having water catching parts.
