Description

[Detailed description of the invention] (Industrial field of application) This invention is applied to joints of a retaining wall constructed on a slope for the purpose of retaining earth, etc. It is related to.

(Problem to be solved by the invention) Piece blocks, reinforcing bars, etc. are usually used to connect the two types of concrete members that make up the parallel retaining wall in an integral manner. The reality is that this has become complicated and requires high assembly precision.

This idea was made based on these circumstances, and attempts to simplify the joint by making the concrete members fit into each other.

(Means for Solving the Problems) In the present invention, the joint part has a structure in which the ends of two types of members fit into each other, thereby eliminating the need for a connecting member and simplifying the joint structure.

The two types of concrete members are the edge members and the longitudinal members that make up the parallel retaining wall, and are placed perpendicularly to each other.
stacked alternately.

An engaging portion and a locking portion having a recess are provided upright on the horizontal surface of the end of the edge member, while a convex portion is provided horizontally protruding from one side of the end of the elongated member. The convex portion has a shape that fits into the recess of the edge member, and one of the two longitudinal members arranged in conjunction with each other fits into the recess of one of the edge members.

(Example) The present invention will be described below based on drawings showing an example.

The joint structure A of this invention is made by fitting the ends of one precast concrete edge member 1 and two longitudinal members 2, 2, which make up the double girder retaining wall B, into each other. .

As shown in Fig. 3, the double-legged retaining wall B is constructed by alternately stacking the edge members 1 arranged vertically to the slope and the longitudinal members 2 arranged horizontally upward. The joint structure A is formed from an edge member 1 end portion arranged at intervals and a longitudinal member 2, two end portions successively installed on the end portion.

As shown in FIG.
On A, a locking part 1B and an engaging part 1C are erected facing each other, and a convex part 2b is provided on one side of the end of the longitudinal member 2, 2.
2b is horizontally protruded. The locking portion 1B has a convex portion 2.
A recessed portion 1b is formed in which the portions b and 2b are connected and fitted.

On the horizontal surface 1A of this edge member 1, as shown in FIG.
is fitted and placed in the recess 1b to form the joint structure A.

(Effects of the invention) As described above, in this invention, one edge member and two longitudinal members fit together to form a joint part, so no special connecting member is required, and it is simply It is possible to construct a retaining wall with double-sided girders by simply piling them up, making it possible to simplify the structure of the joints and simplify the construction.
