Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to members used in the parallel girder construction method, and more specifically, it enables protection of curved slopes, and also protects the slopes in the girder direction (direction perpendicular to the slope). The present invention relates to members used in the double-crossing method, which can be easily installed in multiple rows.

[Conventional technology]

The parallel girder method uses horizontal members along the slope (hereinafter referred to as beam members) and members perpendicular to the slope (hereinafter referred to as girder members).
This is a construction method that protects the slope by constructing a girder system on the slope. This double girder construction method has been used for a long time and can stably create slopes such as rock-filed embankments.
This construction method has excellent properties, such as being able to be constructed rationally using lightweight materials, having good water permeability, and easily constructing slopes with good adaptability to ground subsidence in a short construction period.

Conventionally, the members used in the double-crossing method were concrete rod-shaped members with notched grooves at the ends, which were assembled into double-crossings and connected with bolts and nuts (for example, Utility Model Publication No. 49-114702), without the use of bolts and nuts. In addition, those with an engagement connection using an inset method (for example, Utility Model Application No. 53-16608, Utility Model Application No. 55-76247)
etc. are used.

The types of double-crossings used in the double-crossing method are those in which four members are assembled into a rectangular parallelepiped structure and are simply placed side by side along the slope, or the beams along the slope of the double-crossing are installed in multiple parallelepipeds. It is known that the parallel beams are connected in the horizontal direction by having a length that spans the span, and by disposing the beams in alternating positions forward and backward and up and down. In addition, parallel crossers are also used where long cross beams are arranged in the direction of the crossbeams and supporting crossbeams are provided in the direction of the crossbeams in order to ensure the stability of the slope as necessary.

[Problem that the invention attempts to solve]

Conventional parallel grid members using bolts and nuts have the disadvantage of being time-consuming to install.

If it is necessary to increase the dimension of the parallel girder in the row direction, it is necessary to use a separate girder material that is long in the row direction.

A parallel grid in which parallel crossers are arranged laterally along a slope provides a tight connection in the horizontal direction, but it is difficult to use when the slope is curved.

There are other problems.

The object of the present invention is to provide a parallel cross frame member that has improved the above-mentioned drawbacks of the conventional parallel cross frame, and to further enhance the advantages of the double cross construction method.

The present invention provides a cross-girder method member that can easily form and protect a slope with a curved slope foot, and can easily construct an arbitrary number of multiple cross-link girders in the girder direction. be.

[Means for solving problems]

The feature of this invention to achieve the above purpose is that horizontal connected beams along the slope and girders perpendicular to the slope are combined into a parallel girder, and these are stacked in the height direction. In the cross member forming a surface, the cross member has a unit length, and the engagement groove with the beam material carved near both ends has a groove width parallel to the center and widened at both ends. It is possible to construct a curved slope by forming a curved slope, and the beam material for multiple consecutive installations in the girder row direction is a unit length beam material with an H-shaped cross section. Two rows of notches, in which the engagement grooves of the front and rear girder members engage, are formed at the positions of one quarter and three quarters of the length of the member from the longitudinal ends of the blades of both flanges with an H-shaped cross section. This is a member for the parallel girder construction method that can be installed multiple times in the girder direction, and is characterized by having a recessed part.

The length of the girder material is set to be the unit length of the girder, and the side walls of the engagement grooves with the beam material carved near both ends of the girder material are chamfered so that the girder can be distorted into a diamond shape. It is now possible to construct curved slopes.

[Effect]

In the case of the double stringer construction method member of the present invention, when multiple double stringers are installed in parallel in the row direction, the beam material has two rows of locking parts that are respectively locked by the front and rear stringer members, and these locking parts are There are two rows of notches recessed in the blades of both flanges of the mold cross section, and by locking the girder material in these locking portions, it is possible to freely connect the cross girder materials in multiple rows in the girder row direction. .

In other words, when this beam material is used, a.
By repeating this process, any number of parallel grids can be connected in the row direction. Therefore, even if the ground on the slope to be protected is extremely uneven, or includes valleys or streams, it is possible to arbitrarily construct parallel grids in these depressions.
Stable slope protection can be provided. In this case, there is no need to separately manufacture a long beam member as in the past.

(b) By using one type of beam material and tapering the side surfaces of the girder grooves, it is possible to construct a parallel girder along a curved slope. This allows it to be easily adapted to roads in mountainous areas and curved slopes such as rivers.

The beam material 1 can easily be made of the same members and arranged in series in the beam direction as necessary, and does not require many types of members.

Furthermore, since a long member is not required, it is easy to increase the bending rigidity. Therefore, even in the case of the above-mentioned continuous arrangement, there is an advantage that no separate design is required at all.

The girder 1 has chamfers 7 on the side walls of the grooves 6 that engage the beams 2 and 3, so that the angle of the engagement with the beams 2 and 3 is not limited to a right angle but can be changed. Therefore, in combination with limiting the girder material 1 to a unit length, the well girder using the member of the present invention can be constructed with a slope on a curve, and is compatible with the geographical conditions, geological conditions, and other natural conditions of the construction location. It is possible to design and construct the most rational slope according to the conditions and conditions of use.

When multiple parallel beams are installed in the row direction, a beam member 2 having, for example, an H-shaped cross section is used, which has two rows of locking portions for locking the front and rear stringers, respectively. The beam 2 has a groove 8 that engages with the beam 1. This beam material 2
Therefore, the parallel girders of the present invention can be arranged in multiple rows in an arbitrary number in the row direction, and the length of the girder material can be limited to one type, which is rational.
