Abstract

PURPOSE:To prevent the slackening and coming-off of main frame from connectors by loading of covering soil by a method in which a projected lever is provided to the downside of the cover of a connector connecting the main frames in a hatched form, and holes are projectionally provided in the connector of the main frame. CONSTITUTION:The upper vertical wall 4 of the main body of a main frame 2 is cut off on both ends of the main frame 2, and a hole 65 is instead drilled in the upside of the main body 3. Also, projected levers 66 are formed on the downside of the cover 13 of a connector to connect the main frames 2 in a hatched form. The main frames 2 are placed crosswise on a slope, the cover 13 is made to cover the main frames 2, and the projected levers 66 of the cover 13 are inserted into the holes 65 of the main frames 2. The main frames 2 can thus be prevented from slackening and separating from the connector 2 even when burdened with covering soil.

Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an improvement of a non-drainage frame that prevents collapse of sloped surfaces, which are often found in cut-throughs for railways, roads, etc., and in residential development sites.

(Background technology) Sloped surfaces found in cut-outs, etc. are widely protected by covering them with grass, etc. to prevent them from collapsing due to rainfall after construction. It is also practiced to install a framework on the surface of the slope that protects the slope until it grows and functions as a reinforcing frame even after the growth.

Such a framework can be made of synthetic resin or metal, for example.
A member 1.1 having an abbreviated cross-section as shown in the figure is made, and a large number of the members 1.1 are connected with bolts and nuts to construct a base mesh-shaped framework on an inclined surface as shown in Fig. 2. This is to suppress the surface of the inclined surface.

However, when preventing the slope from collapsing using such a conventional framework, the following disadvantages occur. In other words, since such a framework is simply fixed to the surface of the slope and suppresses the linear 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 the mountain water 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 likely to corrode, and if they corrode, the framework will gradually float on the slope. -, resulting in an unstable state W: where the object simply rests on the inclined surface. Furthermore, since the framework is visible on the ground surface, even if grass or the like grows on a slope, the grass will grow avoiding the framework and the existence of the framework will be visible when viewed from a distance. Therefore, the slope looks artificial, and under special conditions such as natural parks, the aesthetic appearance may be spoiled, which is not desirable.

In order to eliminate such inconveniences, the inventor first connected a large number of main frame members of a certain length with vertical walls on two sides of the main part having a rectangular cross section in a diagonal lattice shape using first connectors. , this first connector has a flow path that introduces moisture flowing down the side of the main frame material into the inside, and the second connector connected to the lower end of the lowermost main frame material allows moisture to flow down inside this main frame. A non-drainage frame for preventing collapse on an inclined surface having an opening for discharging moisture outside the inclined surface was invented (Japanese Patent Application No. 57-77505-Q).

First, to explain in detail the non-collapsing non-drainage frame between the starters, Figures 3 and 4 show that it is used for the frame between the starters to prevent collapse of sloped surfaces and also to remove moisture from the surface layer of several surfaces. The main frame material 2 for discharging is shown. The main frame material 2 has vertical walls 4 formed on two sides of a main part 3 having a rectangular cross section, and a partition wall 5 is formed on the inside of the main part 3 to partition the inside of the main part 3 into upper and lower parts for reinforcement. ing. Both ends of the vertical wall 4 formed on the two sides 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.

The anti-collapse non-drainage frame related to the front space is constructed by forming the main frame material 2 formed in this way into a diagonal lattice shape by tightening the first to sixth connectors 6 to 11, as shown in FIG. A large number of them are connected and buried in the surface layer of the slope so that the upper surface of the standing wall 4 is almost in line with the ground surface. After rain #! The moisture accumulated inside the body surface is removed from the upper surface of the main frame material 2.2 (the side located on the F side of the slope).
It flows toward the connection part of each main frame member 2.2, flows into the main part 3 from this connection part, flows inside this main part 3, and is discharged to the outside of the inclined surface. Therefore, -1 of main frame material 2.2
- The connecting tool installed at the place where the moisture gathered on the side has the function of connecting the main parts 3.3 of the main frame members 2.2, as well as the function of capturing moisture contained in the surrounding soil to the inside. It has both functions.

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. It consists of 4 bodies 13 like this. A circular tube portion 15 is formed in the center of the substrate 14 constituting the main portion 12, and extends vertically through the substrate 14.The outer periphery of the substrate 14 is spaced apart from each other. A plurality of standing walls 16, 17, and 18 are formed, and the main portion 3 of the main frame member 2 described above can be inserted between each standing wall. That is, the lower edge of the substrate 14 (upper and lower are the seventh
According to the diagram. ) is formed with a first chevron-shaped vertical wall 16, and second chevron-shaped vertical walls 17 and 17 are formed on both left and right edges, respectively.
The space between the first and second vertical walls 16.17 is an insertion portion 19.19 into which the main portion 3 is inserted. In addition, the substrate 14
A third standing wall 18.18 parallel to the second standing wall 17.17 is formed on both left and right sides of the upper part of the The insertion portion is 19.19. Furthermore, between the third standing wall 18.18 on the left and right,
- A plurality of square columns 21.21 are formed symmetrically with respect to the standing wall 20 at the center of the L edge, and a compatible wall 18.18
A curved flow path is provided between the two. 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 16 of the main part 12.
．． 17.It is fitted externally to the upper end of 18, and this vertical wall 16
．． It is formed lower than 17.18. Furthermore, the lid body 1
An X-shaped standing wall 26 is formed on the upper surface of the substrate 14 of No. 3, and a support 27 is suspended from the lower surface. The vertical wall 26 on the upper surface aligns with the vertical wall 4.4 on the upper surface of the main frame member 2 connected to the first connector 6 and serves to connect this vertical wall 4.4, and the support column 27 on the lower surface When the first connector 6 is buried in the ground so that it comes into contact with the lower edge of the vertical wall 20 in the center of the main part 12, the vertical wall 20 is bent by the earth pressure and the upper part of the main part 12 is bent. Prevents the curved flow path from being blocked1
to The main frame member 2.2 shown in FIGS. 3 and 4 is connected to an X-shape as shown in part b of FIG. To connect to
The ends of the main frame material 2 are inserted into the four insertion portions 19 of the main portion 12.
19 and then cover it with the lid I3.

Next, as shown in FIG. 5, main frame members 2.2 are arranged horizontally to form the lower side of a water-catching frame 28 which is formed by connecting a large number of main frame members 2.2 in a diagonal grid pattern. 2 and the lower end of the main frame 2.2 arranged at an angle (part C in Figure 5)
The second connecting tool 7 used for has been done. 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 north surface of the substrate 31. The first insertion portions 34.34 for inserting the ends of the main frame member 2.2 are placed on the upper surface of the substrate 31 at an angle of 45 degrees with respect to the vertical wall 32.33, and spaced apart from each other in parallel to each other. The second insertion part 3 is for inserting the lower end of the main frame member 2.2 arranged in the inclined direction between the vertical walls 35 and 36 formed by opening.
7.37 respectively. A horizontal standing wall 32 and an inclined standing wall 3 formed adjacent to two sides of the substrate 31
Protrusions 38 and 39 are formed at slightly different positions on the side surfaces facing each other, and a curved flow path is formed between the compatible walls 32 and 35. A spacer 40 is inserted between the compatible walls 32.35, and prevents the above-mentioned curved wave path from being blocked by 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 protrusions 43 formed on the two sides of the standing walls 36. .43 to form a curved flow path.

Furthermore, the end of the standing wall 33.33 closest to the bottom -
Opposing stands on the upper side! A weir plate portion 44.44 that does not reach up to i 32.32 is formed, and a U-groove portion 45 is provided downward from between the pedestal plate portions 44.44. The bottom surface of this U-groove portion 45 is inclined so as to stand up against the top surface of the substrate 31. In the center part of the board 31, similar to the main part 12 of the first connector 6 described above.

A circular tube portion 46 is formed which penetrates this substrate 31 downwardly. On the other hand, the lid 30 attached to the main portion 29 is
As shown in FIGS. 15 and 16, each vertical wall 32.
33. Hanging wall 47 that fits over one end edge of 35.36.
A vertical wall 4 on the first side of the main frame member 2.2 that is connected to the second connector consisting of the lid body 30 and the main part 29 is attached to the first side of the substrate 50 having 48.49 formed on the edge. Standing wall 5 consistent with .4
1 is formed. 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 . In addition, the board 5
At the center of the lower surface of 0, there is a standing pillar 4 at the center of one side edge of the main part 29
A column 53 is formed that abuts the lower side of the upper end of the column 1 and prevents the column 41 from deforming.

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 member 2.2, this Main frame rate 2.2
It is sufficient to simply insert the ends of the main part 29 into the four insertion parts 34 and 37 and cover the lid 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 used while being rotated 90 degrees clockwise from the orientation shown in Figure 13, it will be used as the connector in section d in Figure 5, which is also rotated 90 degrees counterclockwise. If used in the above, it can be used as a connecting tool for part e in Fig. 5. However, in this case, the end opening 54 (FIG. 18) of the tubular passage formed between the U-groove portion 45 of the main portion 29 and the cover piece 52 of the lid body 30 is closed. In this case, moisture flowing through 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. It is also possible to cover the lid body 56 to form the third connector 8.

Next, as shown in part f in FIG. 5, the fourth connector 9 that connects one end of the main frame member 2.2 to the negative end of the drain frame 28 is shown in FIGS. 23 to 25. As shown in FIG. 2, 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 upper end of the main frame member 2.2, a lid is not necessary.

Furthermore, a fifth connecting tool 10 used at both upper corners of "Fig. 5"
This is constructed in the same manner as the fourth connector 9 described above, except that the angle formed by the two insertion portions into which the main portion 3 of the main frame member 2 is inserted is 45 degrees. 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, the drain frame 28 as shown in FIG. 5 is constructed by joining a large number of main frame members 2.2 and the first to sixth connectors 6 to 11, which are constructed in the manner described above. In this case, a large number of first connectors 6.6 are placed on the sloped surface, and the water extraction part of the main part 12 (the part of the curved flow path consisting of the prisms 21.21) is located above the sloped surface. It is fixed by a stake passing through the circular pipe part 15 of the part 12, and the main frame member 2.2 is passed between this connection A6.6. 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 water collection frame 28 is buried on a slope, the opening 54 of the second connector 7 can be directly brought out of the slope, or the end of another pipe can be connected to this opening 54. The water sent to the second connector 7 through the pipe 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 1O111 as described above, or the end openings of the main frame member 2 are closed without providing any connectors.

In this way, the drainage frame 28 is placed on the two sides of the inclined surface.
! Once this is determined, soil is further placed on top of this drainage frame 28 until the upper end of the vertical wall 4 of the main frame material 2 is flush with the ground surface, and the entire drainage frame 28 is placed on the surface of the slope. Bury it.

In this way, if the first drainage frame is buried in the surface layer of the slope, some of the moisture contained in the ground will be absorbed by the surface layer of the slope. The material present in the main frame material 2 flows down along the upper side of the main frame material 2 and reaches the connecting portion between the main frame materials 2, 2. As mentioned above, the first to third connectors 6 to 8 that connect the main frame material 2.2 have curved flow paths 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 member 2 and sent to the bottom It is discharged from the opening 54 of the second connector 7 to the outside of the inclined surface.

The anti-collapse/drainage frame on the slope for starters is constructed and functions as described above, so that it can efficiently drain moisture that collects within the slope due to rainfall, and the main frame material 2
．． In addition to partitioning the surface surface into a diagonal lattice pattern by 2, the effect of collapse + h is large, and only the upper end of the vertical wall between the narrow main frame material and each connector is visible on the surface of the slope. Therefore, after grass grows on the slope, the existence of the drainage frame becomes invisible, and it has various excellent effects such as not damaging the beauty of natural parks etc. This will cause such inconvenience.

That is, the main frame material 2 constituting the drainage frame body is made of synthetic resin,
Since both ends of the main part 3 of the main frame material 2 are simply inserted into the insertion parts of each connector and connected, when the drainage frame is buried in the M114 surface, the four two sides of the main part 3 are When the load of covering soil is applied to the main frame member 2, the entire main frame member 2 is bent in an arc shape, and both ends of the main part 3 are pulled out from the insertion part of each connector. If the end of the main frame member 2 comes off from the connector in this way, it becomes impossible to drain moisture within the slope by the drainage frame and prevent the surface layer of the slope from collapsing.

(Objective of the present invention) In order to eliminate the above-mentioned disadvantages, the present invention has a structure on an inclined surface that prevents the upper frame member from bending and coming off from the connector even when a load is applied to the upper side surface of the main frame member. The purpose is to provide a non-drainage frame that prevents collapse.

(Structure of the present invention) The collapse-preventing non-drainage frame on an inclined surface of the present invention is arranged in a diagonal lattice shape in the drainage frame according to the previous invention which is constructed and operated as described in 5 above. Holes are bored on the upper surface of both ends of the main part 3 of the main frame material 2, and a protrusion that can freely enter into the hole is provided on the lower surface of the lid of each of the four connectors for connecting a large number of main frame materials 2.2. The main part 3 of each main frame member 2.2 forms a rod and is used when assembling the drainage frame.
A protrusion rod is inserted into the hole on the upper surface of both ends.

That is, at both ends of the main frame member 2, as shown in FIG. 26, the vertical walls 4 on the upper surface of the main portion 3 are cut off, and holes 65 are formed in the upper surface of the main portion 3 instead. On the other hand, on the lower surface of the lid of the connector that connects the ends of the main frame material 2, there are 27th to
As shown in Figure 29 (the illustrated example is the lid 13 for the first connector 6), the number of main frame members to be connected to this connector is the same (four in the case of the illustrated lid for the first connector). A protrusion 66.66 is formed. The position where this protrusion 66.66 is formed is the part located above the insertion part of the main part when the lid is placed on the main part of the connector, and when the lid is placed on the main part. Then, each of the protruding rods 66,66 enters the hole 65 in the upper surface of the end of the main part 3 of the main frame member inserted into each insertion part. Such engagement between the protrusion 66 and the hole 65 is performed not only in the first connector 6 but also in the second, third, and sixth connectors 7.8.11. Further, if necessary, the fourth and fifth connectors 9 and 10 provided on the upper side of the drain frame 28 are also covered with suitable lids and engaged with the holes in the ends of the main frame member.

In this way, in order to connect the ends of the main frame material to the lids of the respective connectors by IK coupling between the holes and the protrusions, a load due to the weight of the two sides of the main frame material 2 was applied. Even in such a case, the main frame member 2 does not bend in an arc shape, and the end of the main frame member 2 can be effectively prevented from being pulled out from the insertion portion of the connector.

(Effects of the present invention) The non-drainage frame for preventing collapse on sloped surfaces of the present invention is constructed as described in 2 below, so moisture accumulated within the sloped surfaces can be efficiently discharged and the collapse prevention effect is achieved. is large, and the frame body is rarely exposed on the slope, so when moss grows on the slope it looks unnatural and lines.In line with the effect of the previous invention, the main frame material is separated from the connector. There is no need to pull out the drain, improving the durability and reliability of the drainage frame.
