Description

[Detailed description of the invention] There have been many types of steel slope frames used to stabilize slopes. However, these slope frames have many types of slope frame materials, and in particular they use joint fittings, so assembly work is complicated and difficult, and when the slope is not a single plane due to curved parts etc. Many of these have drawbacks, such as not being able to be easily installed to match the slope, and the slope frame partially overlapping the slope, creating a kind of waste.

The present invention does not have the above-mentioned drawbacks, and relates to a slope frame that can be assembled into multiple shapes using a steel sheet material manufacturing method. When making a slope frame material by bending one side with an arc of a quarter circle so that the direction changes at right angles, one type is bent upward, and the other type is a corrugated steel sheet. Two types of slope frame materials are made by keeping them in the same direction and bending them downward, and these two types of slope frame materials are used in combination to assemble the slope frame.

A slope frame material bent upward can be rotated 180 degrees so that its end points downward, so there are cases where slope frames are assembled using this method. In this case, the corrugation of the corrugated steel plate is in the opposite direction to that of the slope frame material, which was bent downward from the beginning (see the cross-sectional view of each corrugated steel plate shown in Figure 4), and the directionality of the waves is different in both cases and is the same. Since this is not a slope frame material in the shape of , basically two types of slope frame materials bent in two directions, upward and downward, are used and assembled to form a slope frame.

Hereinafter, the configuration of the present invention will be explained based on the embodiments shown in the drawings.

About the part from approximately the center to one side of a corrugated steel plate of a predetermined length that is straight in the length direction and has corrugations in the width direction with holes for bolt holes and drainage holes for assembly and connection as necessary. When making a slope frame material by bending the end part in a right angle direction leaving a straight part 1 of a certain length including the overlapping joint part with an arc of a quarter circle, the corrugated steel plate is Two types of L-shaped steel plate materials are made by aligning the molds in the same direction, one type having an upwardly bent circular arc portion 2, and the other type having a downwardly bent circular arc portion 3 (see Figure 1). ).

Two types of slope frame materials (L
As shown in Fig. 2, the first slope frame using a combination of shaped steel plate material) is a slope frame material 4 (hereinafter referred to as the downward frame material) which is bent downward from the lowest step on the slope surface. wave at the joint part of the end on the side that is not bent when viewed from approximately the center of The molds are stacked and joined together with tightening bolts 6, and then the downward facing frame material 4 and the upward facing frame material 5 are alternately used in combination and joined in the same way, resulting in exactly continuous wave shapes. Assemble on the frame.

Next, a slope frame having a continuous wave shape is assembled on the upper stage, and the wave shapes of the lower stage and the upper stage are matched, and the slope frames are connected with tightening bolts 7.

Thereafter, using the same method, the necessary number of consecutive wave-shaped slope frames are stacked to form the entire slope frame.

The slope frame members located at each side edge of the slope frame are connected not only to the adjacent slope frame members on the right or left, but also to the slope frame members located at the upper or lower level and joined at the edge. Assemble by overlapping the joint parts of the upper and lower tiers and connecting them with tightening bolts. At the joint between the lower and upper tiers, be sure to arrange the slope frame members so that the corrugations of the downward and upward frame members overlap ( (See Figure 3).

Moreover, the slope frame members located at the side ends of this slope frame are connected to the slope frame members at the side ends of the upper or lower tier, respectively, and have a closed shape. To achieve this closure, as shown in Fig. 3, a slope frame material 4 of the same shape as that of the slope frame material 4 at the side end is placed over the slope frame material 4 so that the wave shapes match, and the direction of the frame materials is adjusted. Then, the leading end of the frame member is connected to the leading end of the upper frame member 5. The slope frame members for this closed connection need not be shorter than the slope frames at other intermediate positions, so that when connected at the normal end positions, an extra portion 8 appears. Therefore, like the slope frame material at the left end of the second row from the bottom in FIG. In order to avoid any problems, it is necessary to shorten the excess portion 8 by connecting it through a connecting bolt hole located further from the end than in the normal case.

At the joint between the slope frame members where the surplus portion 8 appears, the corrugated steel plates are stacked with their corrugations alternately facing in opposite directions (see Figure 4), but at other joints and At the joint between the lower stage and the upper stage, the corrugations of the corrugated steel plates are oriented in the same direction and overlapped (see Fig. 5).

The slope frame in the form of stacking continuous wave shapes assembled in this way can be easily assembled by joining the slope frame materials one by one on the slope, or by assembling two or more in advance. It is also possible to carry it onto the slope and then assemble it further, giving flexibility in assembly, and the shape of each part separated by the slope frame is the same except for the side edges,
The slope frame is placed in a well-balanced manner in terms of slope protection.

In addition, when the main objective is to assemble the slope frame easily and easily, such as on a curved part where the slope has a small curvature, all the slope frames in the first stage should be made of upward-facing frame members, i.e. , frame materials of the same shape alternately rotated 180 degrees and connected are used for each tier, and two types of slope frames are used in combination alternately for each tier, and the left and right sides of each tier are used alternately. With the exception of some parts, the corrugations of the corrugated steel plates at the joints between adjacent slope frame members are set in opposite directions as shown in Figure 4 to avoid meshing and to create a loose state. It can also be assembled.

For the second slope frame, first make a set of four of the same slope frame members with only the downward facing frame members 4, and in each pair, the joints of the slope frame members are waved to each other as shown in Figure 5. The corrugated steel plates are stacked in the same direction and assembled using the tightening bolts 6 to form a nearly square shape, but the corners are rounded due to the location of the arcs of the slope frame material. Assemble the ring-shaped slope frame 9 (6th
(see figure), then a ring-shaped slope frame 10 is assembled in the same direction as when using the downward-facing frame members, using only the upward-facing frame members 5 that are different from this as a set of four. Furthermore, assemble the required number of these two types of ring-shaped slope frames, and on the slope, the straight line part between the rounded corners of the ring-shaped slope frames should be at 45 degrees to the horizontal line. The ring-shaped slope frames are arranged in combination so that they touch different types of frames on the top and bottom, left and right, and the points between the adjacent ring-shaped slope frames are placed at the rounded corners where they touch each other. are connected with tightening bolts to form the required overall slope frame (see Figure 7).

In this way, with slope frames that are assembled by connecting ring-shaped slope frames, it is necessary to first assemble the slope frames in a ring shape in advance, and then connect them further on the slope to assemble the entire slope frame. However, at the joints between slope frame members and between ring-shaped slope frames, the fifth
As shown in the figure, since the corrugated steel plates are assembled with the corrugations in the same direction and interlocked, this is extremely beneficial for the stability of the slope frame, and even if the slope changes in slope or has a curved part. , and can be easily assembled to suit this.

In addition, the first stage is made up of only the ring-shaped slope frame 9 assembled with downward-facing frame materials, and the second stage is made only with the ring-shaped slope frame 10 assembled only with upward-facing frame materials. By changing the type of the ring-shaped slope frame on the left and right, the corrugations of the corrugated steel plates are turned in opposite directions to create a loose connection between the left and right ring-shaped slope frames, as shown in Figure 4, and It is also possible to slightly increase the finished assembled dimensions of the waveforms by the amount that the corrugations do not overlap. In this case, a slope frame that is a combination of ring-shaped slope frames yields a slope with a slightly larger area than a slope frame that uses the same number of slope frame members and combines them in a continuous wave shape. However, as shown in Figure 7, the shape of each part of the slope divided by the slope frame is a ring-shaped part surrounded by four frame members facing the same direction and a ring-shaped slope frame. There are two types: a portion surrounded by each outer periphery.

Whether it is a type of slope frame made by stacking continuous wave-shaped slope frames or a type of slope frame that connects ring-shaped slope frames, most of the joints between the slope frame materials and the connection parts of the slope frames are Alternatively, if all of the corrugated steel plates are assembled so that the corrugations of the corrugated steel plates are in the same direction and overlapped, as shown in Figure 5, the slope frame members will have a large contact area with each other and will be in an interlocking state. Therefore, it is extremely useful for stability as a slope frame.

No matter which shape of slope frame is assembled, if necessary, an outer frame made of corrugated steel plate is attached to the bottom or side edges of the slope frame, overlapping the corrugated shape of the slope frame.
It is also possible to improve the dimensional accuracy when assembling the slope frame and to make the assembled slope frame as a whole stronger.

As explained above, the slope frame according to the present invention uses an L-shaped steel plate material made by bending a directional corrugated steel plate upward so that the bent portion has a circular arc, and an L-shaped steel plate material made by bending a directional corrugated steel plate in the same way downward. basically 2
It can be assembled into various shapes, and the combination and assembly method can be selected as appropriate, such as by changing the orientation of the corrugated steel plate at joints and joints to suit the conditions that best suit the slope. In any of these assemblies, it is possible to join or connect by simply tightening the connecting bolt holes of the slope frame material directly with bolts, without using any special fittings. The work is extremely simple and easy, which shortens the construction period and reduces construction costs, and it can be easily and adequately applied to slopes with changing slopes or slopes on curved sections. It is a slope frame with many excellent features, such as being able to be assembled easily and being highly stable and strong.
