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 technology) In order to prevent sloped surfaces found in cut-outs and the like from collapsing due to rain, etc. after construction, the surface is often covered with grass or the like to protect the surface. 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 synthetic resin or metal, for example, with a first
As shown in the figure, members 1 and 1 having a cross-section with a cross-section are made, and a large number of the members 1.1 are connected with bolts and nuts, and a framework with a base pattern as shown in Fig. 2 is made on an inclined surface. This structure suppresses 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. In addition, the intersection of the framework (the second
Part a) in the diagram is identified with respect to the slope using wooden stakes, U-shaped metal rods, etc., but since the intersection is the part where rainwater that falls on the slope is most likely to accumulate as it is guided by the framework. The wooden stakes, U-shaped metal rods, etc. mentioned above corrode easily, and when they corrode, the framework gradually floats up onto the slope, leaving it in an unstable state where it simply rests on the slope. I end up. Furthermore,
Because the framework is visible on the ground surface, even if grass grows on a slope, the grass will grow avoiding the framework, and the existence of the framework can be seen when viewed from a distance, so it is difficult to avoid slopes. The surface looks artificial, which is undesirable under special conditions such as natural parks, as it impairs the aesthetic appearance.

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 non-drainage frame that prevents collapse on an inclined surface and has an opening for discharging water to the outside of the inclined surface (Japanese Patent Application No. 77505, No. 1977).

First, to explain in detail the anti-collapse non-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 extract 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 directly opposite the connection described later.

In the collapse-prevention drainless frame body according to the previous invention, the main frame members 2 formed in this manner are connected in large numbers in a diagonal lattice shape by first to sixth connectors 6 to 11, as shown in FIG. Then, standing wall 4
It is buried in the surface layer of a slope so that its top surface is almost flush with the ground surface. The moisture accumulated in the sloped grapes after rain is guided by the upper fabric of the main frame material 2.2 (the side surface located on the north side of the slope surface) and flows toward the connection part of each main frame material 2.2, It 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 connection tool installed at the place where the moisture guided on the two sides of the main frame material 2.2 collects has the function of connecting the main parts 3.3 of the main frame material 2.2, as well as the function of connecting the main parts 3.3 of the main frame material 2.2. It also has a water-capturing function that draws moisture contained in the soil into the soil.

That is, the first connector 6 that connects the main frame members 2.2 disposed in the construction direction in an X-shape is connected to the main part 12 as shown in FIGS. 6 to 9 and as shown in FIGS. It consists of a lid body 13 as shown. A circular tube portion 15 is formed in the center of the 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 at intervals on the outer peripheral edge of the substrate 14, and the main portion 3 of the main frame member 2 described above can be inserted between each vertical wall. It has become. That is, a first chevron-shaped vertical wall 16 is formed on the lower edge of the substrate 14 (the second part is shown in FIG. 7), and second chevron-shaped vertical walls 17 and 17 are formed on both left and right edges, respectively. An insertion portion 19.19 into which the main portion 3 is inserted is formed between the second vertical walls 16.17. In addition, the board 1
A third standing wall 18.18 parallel to the second standing wall 17.17 is formed on both the left and right sides of the second part of 4, and the main part 3 is also inserted between the second and third standing walls. Insert part 19.19 for
It is said that Further, between the left and right third standing walls 18.18, a plurality of square columns 21.21 are formed symmetrically with respect to the standing wall 2o at the center of the upper edge.
A curved flow path is provided between 8 and 8. 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. It forms hanging walls 23, 24, 25. Each hanging wall 23, 24, 25 is a vertical wall 1 of the main part 12.
6.It is fitted externally to the upper ends of 17 and 18, and this vertical wall 1
It is formed lower than 6.17.18. Further, an X-shaped vertical wall 26 is formed on two sides of the base plate 14 of the lid body 13, and a column 27 is suspended from the lower surface. The vertical wall 26 on the upper surface aligns with the 1γ wall 4.4 on the L side of the main frame member 2 connected to the first connector 6 and serves to connect this vertical wall 4.4, and serves to connect the pillar 27 on the lower surface. , the upper surface is - of the main part 12.
If the first connector 6 is buried in the ground by contacting the lower edge of the i'Z wall 20 in the center of the section, the upper part of the main section 12 will bend due to the earth pressure. This prevents the JIiii curved flow path provided in the pipe from being blocked. The first connecting device 6 consisting of the main portion 12 and the lid body 13 formed in this way connects the third
~The main frame material 2゜2 shown in Figure 4 is
In order to make a shape connection, it is sufficient to simply insert the ends of the main frame member 2 into the four insertion portions 19, 19 of the main part 12 and cover the lid body 13 from above.

Next, as shown in FIG. 5, main frame members 2.2 are arranged horizontally to form the lower side of the drainage frame body 28, which is formed by connecting a large number of main frame members 2.2 in a shoulder grid pattern. The second connector 7 used for connecting the lower end of the main frame member 2.2 arranged by tilting the screw 4 (portion C in Fig. 5) is a main frame member 2.2 as shown in Figs. part 29 and a lid body 30 as shown in FIGS.
team up with The main portion 29 is formed symmetrically as shown in FIG. 13, and is horizontally arranged between vertical walls 32 and 33 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 part 34.34 for inserting the end of the main frame member 2.2 is inserted into the vertical wall 32.33 at 4.
A groove for inserting the lower end of the main frame member 2.2 arranged in an inclined direction between vertical walls 35, 36 formed parallel to each other and spaced apart from each other on the upper surface of the substrate 31 at an angle of 5 degrees. Two insertion portions 37, 37 are provided, respectively. Protrusions 38 and 39 are formed at slightly different positions on opposing sides of the horizontal standing wall 32 and the inclined standing wall 35 formed adjacent to the upper 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 32.35, and prevents the bent flow path from being blocked due to the bending of the vertical walls 32.35.

Moreover, a plurality of standing pillars 41.42 are formed between the standing walls 36.36 formed near the center of the uppermost part, and a protrusion 43 formed on the 1-side surface of these standing pillars 41.42 and the above-mentioned standing wall 36.36. .43 to form a curved flow path.

Furthermore, a weir plate portion 44.44 that does not reach the opposing vertical wall 3.2.32 is formed on the upper side of the center end of the lowermost wall 33.33, and this art platform plate portion 44.44 A U-groove portion 45 is provided extending downward from between.

The bottom surface of this U-groove portion 45 is inclined so as to be ˜1 upward relative to the top surface of the substrate 31. In the center of the board 31,
Similar to the main part 12 of the first connector 6 described above, this board 3
A circular tube portion 46 is formed that vertically passes through the tube 1 . On the other hand, as shown in FIGS.
5.36 hanging wall 47.48.49 fitting over the upper edge
is formed on the edge of the main frame member 2. which is connected to the second connector consisting of the lid body 30 and the main part 29.
A standing wall 51 is formed that matches the standing wall 4.4 on the −L plane of No. 2. 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 . Further, a post 53 is formed at the center of the lower surface of the substrate 50, above the vertical pillar 41 at the center of the upper edge of the main portion 29, and abuts against the side surface of the terminal to prevent the vertical pillar 41 from being deformed. The second connector 7 consisting of the main portion 29 and the lid body 30 formed in this way is assembled as shown in FIGS. 17 and 18, but in order to connect the main frame member 2.2,
The ends of this main frame material 2.2 are inserted into the four insertion portions 3 of the main part 29.
4. Just insert it into 37 and cover the attracting body 30 from above.

Next, as shown in parts d and e of Fig. 5, a third part is connected to the main frame member 2.2 disposed in the diagonal direction to the main frame member 2.2 disposed in the vertical direction on the inclined surface. The connector 8.8 can be exactly the same as the second connector 7 described above, just by changing the orientation. In other words, if the second connector 7 is rotated 90 degrees clockwise from the orientation shown in Figure 13, it can be used as the connector d in Figure 5 when also rotated 90 degrees counterclockwise. If used, they can each be used as a connector for the part e in FIG. However, in this case, the end opening 54 (FIG. 18) of the tubular passage formed between the U groove 45 of the main portion 29 and the cover 52 of the lid 30 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 fourth connector 9 that connects the upper ends of the main frame members 2 and 2 at the upper end of the drain frame 28 is connected as shown in FIGS. 23 to 25. , an insertion portion 58.58 into which the main portion 3 of the main frame member 2 is inserted is formed substantially perpendicularly to the upper surface of the circular tube portion 57. Since this fourth connector 9 simply locks the −L end of the main frame member 2.2,
A lid is not required.

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 of the series. 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, a large number of main frame members 2.2 configured in a series and the first to sixth connectors 6 to 11 are joined to form a drainage frame 28 as shown in FIG. In this case, a large number of first connectors 6, 6 are placed on the inclined surface, and the bolted part of the main part 12 (the part of the curved flow path consisting of the prisms 21 and 21) is located above the inclined surface. The main frame member 2.2 is fixed by a stake passing through the circular pipe portion 15 of the main portion 12, and the main frame member 2.2 is hung between the connectors 6.6. In addition, the lower part of the drainage frame 28 has 13th to 18th
The second connector 7 as shown in the figure is similarly fixed with a stake penetrating the circular tube part 46, and the first and second insertion parts 34, 37
Insert the end of the main frame material 2 into. When the entire drainage frame 28 is buried on an inclined surface, the opening 54 of the second connector 7 can be directly brought out of the inclined surface, or the end of another pipe can be connected to this opening 54, and this pipe can be connected to the opening 54. The water sent to the second connector 7 through the drain is discharged to the outside of the inclined surface. Furthermore, the drainage frame body 2
The third connector 8 is similarly fixed to the left and right sides of the frame 8 with stakes, and the end of the main frame member 2 is inserted. In addition, the drainage frame 2
A fourth connector 9 is fixed to the upper side of 8 with a stake to lock the upper end of the main frame member 2. Furthermore, the four corners of the drain frame 28 are also connected to the fifth and sixth connectors 10111 as described above, or the end openings of the main frame member 2 are closed without any connectors.

Once the drain frame 28 has been fixed to the upper surface of the slope in this way, the drain frame 28 can be further fixed on top of the drain frame 28.

The drain frame 28 is entirely buried in the surface layer of the slope by covering the main frame 2 until the upper end surface of the vertical wall 4 coincides with the ground surface.

When the collapse-preventing non-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 flows down along the upper side of the main frame member 2 and reaches the connection part of this main frame member 2.2. As mentioned above, the first to third connectors 6 to 8 that connect the main frame material 2.2 have curved channels that take moisture flowing from above into the main frame member 2.2. The moisture flowing down the upper surface of the frame material 2 enters into the first to third connectors 6 to 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 collection is performed for each of the many connectors 6.7.8 that make up the drainage frame 28, and the collected moisture is collected in the main part 3 of the main frame material 2 and collected in the bottom It is discharged from the opening 54 of the second connector 7 to the outside of the inclined surface.

The collapse-preventing non-drainage frame for use on 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 discharged, and the main frame material 2
．． 2, which partitions the surface surface into a diagonal lattice pattern, has a great effect in preventing collapse, and the only thing visible on the surface of the slope is the top end of the vertical wall between the narrow main frame material and each connector. Therefore, once grass grows on the slope, the existence of the drainage frame becomes invisible, and it has various superior effects such as not spoiling the beauty of natural parks etc. During construction, the following problems arise.

That is, each of the first to third connectors 6.7. has a water catching function.
When burying water pipes 8, crushed stones should be placed around the water extraction parts in order to prevent the water extraction parts of each connector 6, 7 and 8, which are formed by vertical pillars and protrusions to form curved channels, from becoming clogged with earth and sand. must be invested. However, soil must be added to the area outside the water extraction area to improve the growth of the grass planted on the surface, making the work of burying the collapse prevention/drainage frame complicated.

(Objective of the present invention) In order to solve the above-mentioned disadvantages, the present invention is designed to prevent clogging even when soil is poured around the water extraction part, and to efficiently perform the work of burying the collapse prevention and drainage frame. The purpose is to provide connectors that can be used to

(Structure of the present invention) The collapsing-prevention drainless 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 having a water extraction part between which the inside and outside are communicated, and a lid that covers this main part, and the water extraction part of the main part is filled with a filter material.

(Action of the present invention) The collapsing prevention non-drainage frame connection tool for sloped surfaces of the present invention configured as described above has a connection tool on the outer surface of the main frame material, as in the case of the connection tool according to the previous invention. The water that flows down along the line is introduced inside through the extraction 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 extraction 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 the space between the first and second standing walls 16.17 is an insertion part 19.19 for inserting the main part 3 of the main frame material 2, and the board 1
A third standing wall 18.18 and a second standing wall 17.17 formed in parallel with the second standing wall 17.17 on both the left and right sides of the upper part of 4.
In the main part 3, a similar insertion part 19.19 is provided between the third vertical wall 18.18, and a water catching part 59 provided between the third vertical wall 18.18 is filled with a coarse fibrous filter material 60. ing. That is, on the upper edge of the flat plate portion located between the third vertical walls 18.18, there are a plurality of pillars 61. with a triangular cross section spaced apart from each other.

8 supports the filter material 6o so that it does not come out downward from between the third vertical walls 18, 18.

Since the collapse-preventing non-drainage frame connector for sloped surfaces of the present invention is constructed as described above, if it is to be buried underground, crushed stone is specially placed around the water extraction part 59. Even if you do not do so, this water will not enter the inside of the connector just by adding soil, and the water that collects near the water extraction part 59 along the upper side of the main frame material 2 will also pass through the filter material 6o. can be collected. In the illustrated embodiment, a plurality of through holes 64, 64 are formed in the portion of the substrate covered with the filter material 6o. This through hole 64.
A reference numeral 64 serves to introduce moisture that has not been completely extracted in the water capturing portion 59 and has entered the lower side of the connector into the inside of the connector.

(Effects of the present invention) Since the collapsing prevention non-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 explained in which a filter material was provided in the insertion part of the first connecting tool 6 that connects the main frame material in an X-shape. This is applied not only to the first connector 6 but also to the other second and third connectors 7.8 having water catching parts.
