Description

[Detailed Description of the Invention] (Technical Field) The present invention provides a connection tool that can be used to prevent collapse of sloped surfaces and constitute a drainage frame that is often found in cut-outs for railways, roads, etc. and residential development sites. The present invention relates to a method of fixing on top of a vehicle and a fixing device for direct use in carrying out this method.

(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
Make members 1 and 1 with an abbreviated cross-section as shown in the figure, and connect a large number of the members 1 and 2 with bolts and nuts to construct a base mesh-shaped framework on an inclined surface as shown in Figure 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 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 prone to corrosion, and when they corrode, the framework gradually floats onto the slope. It simply climbs up the slope.
This results in an unstable situation where it is only listed in second place. 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. The surface looks artificial, which is undesirable under special conditions such as natural parks, as it impairs the aesthetic appearance.

In order to eliminate this inconvenience, the inventor of the invention first connected a number of main frame members of a certain length each having a vertical wall 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 of the main frame material into the inside, and the second connector that is connected to the bottom end of the main frame material at the lowest end has a flow path that introduces moisture that has flowed down the main frame Murayama. He invented a collapsing and drainage frame for sloped surfaces that has an opening for draining water to the outside of the sloped surface (Japanese Patent Application No. 77505/1983).

First, to explain in detail the collapse prevention/drainage frame for the first mover, Figures 3 and 4 show that it is used for the first mover frame to prevent collapse of sloped surfaces and also to remove moisture from the surface layer of line surfaces. The main frame material 2 for discharging 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.

The anti-collapse/drainage frame for the first use is constructed by connecting a large number of the main frame members 2 formed in this manner in a diagonal lattice shape using 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. After rain, the moisture accumulated in the slope is guided by the upper side of the main frame member 2.2 (the side surface located above the slope) and flows toward the connection part of each main frame member 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 in the place where the moisture guided on the upper side 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 with each other. It also has a water-capturing function that draws the moisture contained in the water inside.

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 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 on the outer peripheral edge of the substrate 14 at intervals, so that 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 lower 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 for inserting the main portion 3 is formed between the second vertical walls 16.17. In addition, the board 1

The insertion part 19.19 is used. Further, between the left and right third standing walls 18.18, a plurality of prisms 21.21 are formed symmetrically with respect to the standing wall 20 at the center of the upper edge.
A curved flow path is provided between the two. On the other hand, as shown in FIGS. 1O to 12, the lid 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 with the first connector 6 in contact with 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 a part of the main part 12 is bent. Prevents the provided curved flow path from being blocked. The main frame member 2 shown in FIGS.

34 is inclined by 45 degrees with respect to the standing walls 32 and 33, and the main frame member 2 is disposed in the inclined direction between the standing walls 35 and 36 formed parallel to each other and spaced apart from each other on the upper surface of the substrate 31. .2 second insertion part 37.37 for inserting the lower end of the
are provided for each. 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 protrusions 43. 43 to form a curved flow path. Furthermore, a weir plate portion 44.44 that does not reach the opposing vertical wall 32.32 is formed on the upper side of the end of the lowermost standing wall 33.33 near the center, and a weir plate portion 44.44 is formed between the two weir plate portions 44.44. A U-groove portion 45 is provided extending downward. The bottom surface of this U-groove portion 45 is inclined upwardly with respect to the top surface of the substrate 31.

The main portion 1 of the first connector 6 described above is located in the center of the board 31.
2, a circular tube portion 46 vertically passes through this substrate 31.
is formed. On the other hand, as shown in FIGS. 15 and 16, the lid body 30 attached to the main part 29 has a hanging wall 47. 48.49 is formed on the edge portion of the substrate 50, aligned with the vertical wall 4.4 on the upper surface of the main frame member 2.2 connected to the second connector consisting of the lid body 30 and the main portion 29. A vertical wall 51 is formed. Further, the lower end edge of the lower hanging wall 47 has an arcuate cross section, and the U groove portion 45 of the main portion 29 described above
A cover piece 52 is formed to cover the upper side. Further, at the center of the lower surface of the board 50, a vertical pillar 4 at the center of the upper edge of the main portion 29 is provided.
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 part 29 and the lid body 30 formed in this way can be assembled as shown in FIGS. , this main frame material 2.
All that is required is to insert the ends of 2 into the four insertion parts 34 and 37 of the main part 29 and cover the lid 30 from above.

Next, as shown in parts d and e of Fig. 5, the main frame members 2 and 2 arranged in the diagonal direction are connected to the main frame members 2 and 2 arranged in the vertical direction on the inclined surface. The third connector 8.8 can be used by simply changing the orientation of the second connector 7 described above. First, rotate the second connector 7 clockwise from the orientation shown in Figure 13. If used with the connector rotated 90 degrees to
If used in a rotated state, they can be used as the connectors shown in section e in Figure 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 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 19th to 20th
The third connector 8 can also be formed by attaching a lid 56 as shown in FIGS. 21 and 22 to the main portion 55 as shown in the drawings.

Next, as shown in part f in FIG.
As shown in FIGS. 23 to 25, an insertion portion 58, 58 is formed on the upper surface of the circular tube portion 57 in a substantially perpendicular direction into which the main portion 3 of the main frame member 2 is inserted. This fourth connector 9 is
Since it simply locks the upper end of the main frame member 2.2,
A lid is not required.

Furthermore, the fifth connector 10 used at both upper corners in FIG. The above-mentioned fourth connector 9
Configure in the same way as . 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 like two sides and the first to sixth connectors 6 to 11 are joined to form a drainage frame 28 as shown in FIG. To do this, a large number of first connectors 6.6 are placed on the inclined surface, and the water extraction part of the main part 12 (the part of the curved flow path consisting of the square columns 21.21) 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 2h 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 two sides of 8 with stakes 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 10.11 as described above, or the end openings of the main frame member 2 are closed without providing any connectors. .

Once the drainage frame 28 has been fixed to the upper surface of the slope in this way, cover the drainage frame 28 with a top until the upper end surface of the vertical wall 4 of the main frame material 2 is in line with the ground surface. , the entire drainage frame 28 is buried in the surface layer of the slope. At this time,
Put crushed stone around the water extraction part (a curved channel made of square columns, etc., or a net) provided in the third connection to prevent the water passage that makes up this water catchment part from becoming clogged. .

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 main frame member 2.2 runs along the upper side of the main frame member 2 and reaches the connecting portion 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 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 then flows into the main frame material 2. It flows further downward inside the . 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 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 what is visible on the surface of the slope is only 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 troubles arise.

That is, each of the first to sixth connectors 6 to 11 is fixed on the slope by a stake, but the remaining connectors 6.7.8.11 except the fourth and fifth connectors 9.10 are Lid body 13.30.56
The main part 12. of each connector 6.7.8.11 has a
After fixing 29.55 on the slope with stakes, each main part 1
The lid 13.30.56 must be fixed to 2.29.55 with adhesive. As described above, it is troublesome to fix the lid body with adhesive after fixing the main part with stakes, and in addition, at civil engineering work sites, there are many opportunities for dirt to adhere to the adhesive surface. If it adheres, it is not preferable because adhesion will not be carried out well.

(Objective of the present invention) The present invention solves the above-mentioned inconveniences and provides a fixing method that can easily and reliably fix a drain frame connector to an inclined surface, and a device that can be used directly to carry out the method. is intended to provide.

(Structure of the present invention) a. Structure of the fixing method The method of fixing the connector for a non-collapse non-drainage frame on an inclined surface according to the present invention is to first place the main part of the connector to be fixed on the inclined surface. After this, a pile with a flange in the middle and a male thread on the upper side and a sharp end on the lower end is inserted from above into the circular pipe part provided by penetrating the base plate of the main part. The main part is fixed on the slope by driving it into the slope, and then a lid having a circular hole in the base plate is placed over the main part, and at the same time, the upper end of the male thread on the top of the pile is inserted through the circular hole into the upper surface of the lid. protrude, screw the nut onto the end of this male thread,
Make sure the lid does not come off from the main part.

b. Structure of fixing device The fixing jig for the connection device for the drainage frame to prevent collapse on an inclined surface of the present invention includes a stake for fixing the connection device to the inclined surface;
It consists of an auxiliary tool used when driving the pile.

The piles are made of metal or hard synthetic resin.
A flange with a larger diameter than the circular pipe part provided on the main part of the connecting device to be fixed in the middle is formed, and the part below this flange is made sufficiently longer than the circular pipe part mentioned in "2" and its lower end is sharpened. The end and above the flange is a male thread.

Further, this pile driving auxiliary tool is formed into a bottomed cylindrical shape having an inner diameter smaller than the outer diameter of the flange and larger than the male threaded part, and a circular hole deeper than the length of the male threaded part. ing.

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

26 and 27 show the fixing device of the present invention, FIG. 26 is a side view of the stake 59 and the nut 61, and FIG. 27 is a side view of the auxiliary tool 60 used when driving the pile. It is.

Pile 59 made of hard synthetic resin or metal such as iron
is a male thread 6 extending upward from the center of two sides of the flange 63 provided at the upper end of the pile portion 62 with the lower end 62a as a sharp end.
There are 4. Of this pile 59, the length of the pile part 62 is formed to be sufficiently longer than the length of the circular pipe part provided in the main part of the connector to be fixed, and the pile part 62 is inserted into this circular pipe part. However, the flange 63 prevents entry into this circular pipe portion. The male screw 64 has a shape H in which the lower surface of the flange 63 is in contact with one end surface of a circular tube formed in the main part of the connector to be fixed, and the other end is attached to a lid body that covers this main part. Form the length so that it slightly protrudes from the top surface. The nut 61 is provided with a screw hole in the center thereof into which the male screw 64 is screwed. Since this nut 61 is not strongly screwed into the male screw 64, it does not need to be a hexagonal nut that can be turned with a spanner. This makes it easy to turn.

Further, the auxiliary tool 60 used when driving the pile 59 into the slope is formed in the shape of a cylinder with a bottom as a whole, and the depth of the circular hole 65 into which the male screw 64 described in -1- can be freely inserted is as follows. It is slightly deeper than the length of this male thread 64. A locking portion 66 is provided on the outer peripheral surface of this auxiliary tool 60, and one end of the locking portion 66 is connected to the other end of a chain or the like, which is connected to a worker's belt or the like. This chain is made to have a sufficient length so that the operation of driving a pile 59, which will be described later, can be performed with both ends of the chain connected.

Among the connectors fixed on the slope using such a fixing device, the main part has the same structure as the main part of the connector used for the non-collapsing non-drainage frame of the previous invention, but the lid 13 (Although only the lid 13 for the first connector is illustrated, the second,
The same applies to the third and sixth connectors 7.8 and the IT lid 30.56. ), as shown in FIG. 28, a circular hole 67 is bored through which the male screw 64 at the top of the pile 59 can be inserted.
A part of the vertical wall 26 formed on the upper surface of this lid body 13 is used to form a circular hole 6.
The parts around 7 are excluded.

Using the fixing device configured as described in 2 below,
The procedure for fixing the collapse-preventing non-drainage frame connector, which has a circular hole in the lid, on the inclined surface is as follows.

First, place the main part 12 of the connecting tool 6 at a predetermined location on the slope, insert the stake part 62 of the stake 59 into the circular tube part 15 of the main part 12 from above, and stick the lower end 62a into the slope. . Next, the auxiliary tool 60 shown in FIG. Drive it into the inclined surface until it comes into contact with the upper end surface of the circular tube part 15. As a result, the main part 12 is fixed on the inclined surface. Next, the auxiliary tool 60 is removed from the male screw 64, and the lid body 13 is placed over the main part 12.
The two ends of the male screw 64 are made to protrude from the circular hole 67 to the two sides of the lid body 13, and the upper end of the male screw 64 is screwed into the number nut 61, as shown in FIG. This prevents the lid 13 from coming off from the main portion 12 by holding it against the upper surface of the lid 13.

Since the NAND 61 only needs to prevent the lid 13 from coming off when the anti-collapse non-drainage frame is installed on an inclined surface, it is not necessary to strongly tighten the NAND 61 to the male screw 64.

In addition, although the above-mentioned explanation was performed only about the first connection tool 6, it can be performed in exactly the same way about fixing of the other connection tool which has a lid body.

(Effects of the present invention) The method and fixture for fixing the connection tool for a non-collapsing non-drainage frame on an inclined surface according to the present invention are configured and implemented as described above. The connecting tool can be easily and reliably fixed.

In addition, an auxiliary tool 60 is provided to drive the pile 59 constituting the fixing device, and force is applied to the flange 63 of the pile 59 through this auxiliary tool 60 when driving the pile. When driving piles, crush the top end of the male screw,
It won't be difficult to screw together the rear glass.
