Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a double girder retaining wall for stabilizing slopes such as earth retaining.

[Problems to be solved by the invention]

Up until now, several well-structured retaining walls that are constructed by assembling concrete members by using piece blocks, reinforcing bars, etc. for connection have been developed, but it takes time and effort for construction because it requires piece blocks, reinforcing bars, etc. Also, the accuracy of assembly is required.

For this reason, the applicant of the present application filed Japanese Utility Model Application No. 60-165571 (actual fairness 2
-11476), a device in which a rubber packing is interposed between a horizontally continuous long member and a small member stacked so as to intersect with the long member is disclosed.

However, if the width of the rubber packing is wide, when the left and right ends of the longitudinal member are slightly tilted up and down, there is a problem that the tilt cannot be allowed to be too large.

An object of the present invention is to provide a cross girder retaining wall that is easy to assemble, absorbs vertical displacement of longitudinal members and errors in member accuracy, and also absorbs vibrations such as earthquakes to prevent damage to members. To do.

[Means for solving problems]

The narrow rubber packing of the retaining wall of the double girder assembly according to the present invention is used.

In this invention girder set retaining wall, a plurality of horizontally continuous precast concrete longitudinal members are arranged in front and rear, and a plurality of precast concrete forehead members are appropriately separated in a direction intersecting with the front and rear longitudinal members. Arranged and alternately stacking the longitudinal member and the small member, to form a cross girder-like retaining wall, above and below the end of the longitudinal member, at a position slightly apart from the tip, long in the direction orthogonal to the longitudinal direction. The rectangular rubber packing whose long side is equal to the width of the longitudinal member is positioned, and the rubber packing is interposed between the upper and lower edge members and the longitudinal member for assembly.

〔Example〕

The present invention will be described below with reference to the drawings showing an embodiment.

The cross girder retaining wall A is constructed by alternately arranging the small member 1 and the longitudinal member 2 made of precast concrete in a cross girder shape.

As shown in FIG. 1, the fore edge member 1 is formed by vertically arranging the engaging portions 1a on the upper and lower surfaces of both ends, and is arranged in the fore edge direction of the double girder retaining wall A, that is, in the direction perpendicular to the longitudinal direction. The engaging portion 1a has a concave portion 1 having a shape in which the convex portion 2a of the longitudinal member 2 is fitted.
b is formed.

Similarly, as shown in FIG. 1, the longitudinal member 2 is formed by horizontally projecting a convex portion 2a having a shape that fits into the concave portion 1b of the locking portion 1a of the edge member 1 on one side surface of both ends. It is arranged in the longitudinal direction of the wall A.

A method of assembling both members formed as described above will be described with reference to FIG.

First, the small members 1 are arranged on the basic concrete 3 at intervals in the vertical direction of the slope, and the both ends of the longitudinal members 2 and 2 are placed on the both ends of the small members 1 and 1 over them. , Recess 1
The b and the convex portion 2a are fitted together. At this time, the convex portions 2a, 2a of the longitudinal members 2, 2 adjacent to each other are connected to the concave portion 1b so as to be fitted therein.

Further, the edge member 1 is placed on the upper surface of the longitudinal members 2, 2 straddling both ends thereof, with the concave portion 1b of the lower surface thereof fitted to the convex portion 2a.

As described above, the edge member 1 and the longitudinal member 2 are alternately stacked, and the rubber packing 4 is interposed at the intersection of the edge member 1 and the longitudinal member 2. The rubber packing 4 has a rectangular shape whose long side is equal to the width of the longitudinal member 2, and the rubber packing 4 is positioned above and below the left and right ends of the longitudinal member 2. The rubber packing 4 is arranged so that its longitudinal direction is orthogonal to the longitudinal direction of the longitudinal member 2.
Further, the rubber packing 4 is located at a position slightly apart from the tip of the longitudinal member 2.

An embodiment in which the rubber packing 4 is arranged is shown in FIGS. FIGS. 4 to 6 show the case where rubber packings 4 and 4 are arranged above and below adjacent longitudinal members 2 and 2, respectively, on the left and right sides of the concave portion 1b of the foraminous member 1 in parallel with the longitudinal direction of the foraminous member 1. The packings 4 and 4 are placed, and the rubber packings 4 and 4 are placed near the ends of the upper surfaces of the longitudinal members 2 and 2 so as to be orthogonal to the longitudinal direction of the longitudinal members 2 and 2.

If the end portions of the longitudinal members 2 and 2 are assembled on the rubber packings 4 and 4 of the edge member 1 respectively, the rubber packings 4 and 4 are located above and below the left and right end portions of the longitudinal member 2, respectively. ,
Moreover, the rubber packings 4 and 4 are arranged so as to be orthogonal to the longitudinal direction of the longitudinal member 2.

FIGS. 7 to 9 show an embodiment in which the rubber packing 4 is arranged at the end of the longitudinal member 2 located at the end, and the rubber packing 4 is parallel to the longitudinal direction of the formal member 1 corresponding to the concave portion 1b of the formal member 1. The rubber packing 4 is placed on the rubber packing 4, and the rubber packing 4 is placed on the end of the longitudinal member 2 in correspondence with the convex portion 2a. The end portion of the longitudinal member 2 is put on the rubber packing 4 of the forehead member 1 so as to be assembled. In this way, the rubber packing 4 is located above and below the end of the longitudinal member 2, and the rubber packing 4 is attached to the longitudinal member 2.
Are arranged so as to be orthogonal to the longitudinal direction of the.

In the above manner, the small member 1 and the long member 2 are alternately stacked and arranged in the shape of a cross girder so as to be continuous in the longitudinal direction of the long member 2, and the inside surrounded by the members 1 and 2 is filled with the interlocking stone 5, Two
The girder retaining wall A shown in the figures and 3 is constructed.

In this way, the rubber packing 4 is provided between the edge member 1 and the longitudinal member 2.
In the case of interposing, the manufacturing error t between the adjacent longitudinal members 2 and 2 can be absorbed and the edge member 1 can be placed on the longitudinal members 2 and 2 without rattling, as shown in FIG.

Further, as shown in FIG. 11, even if the longitudinal member 2 is tilted α, the narrow rubber packings 4 and 4 are vertically arranged so as to be orthogonal to the longitudinal direction, and are located at a position slightly apart from the tip. As a result, the free soil having the inclination α of the longitudinal member 2 can be made larger, and the longitudinal member 2 can be prevented from being damaged.

[Effect of device]

This invention has the above-mentioned structure, uses a rectangular rubber packing that is long in the direction orthogonal to the longitudinal direction and has a long side equal to the width of the longitudinal member, and a small edge member at a position slightly apart from the tip of the longitudinal member. Since the conventional packing is shared by the adjoining longitudinal members because it is interposed between the longitudinal member and the longitudinal member, separate packings are used in the present invention. Therefore, it easily deforms in response to the inclination or dimensional error of the longitudinal member,
Moreover, the error can be absorbed, and the vibration can be absorbed surely.
