Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double wall structure and a double wall structure using the double wall structure and the double wall structure,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a double wall structure using a double wall structure and a double wall structure, And a method of constructing a double wall structure using a double wall structure.

1 is an attempt at constructing a conventional wall structure in connection with the present invention.

It can be seen that the wall structure is composed of a bottom plate 10, a wall 20 and an upper plate 30.

The bottom plate 10 is usually constructed so as to have a predetermined thickness due to the installation of the site concrete 15 and is usually constructed by placing the concrete between the lower portions of both walls after the two walls 20 are first installed do.

The wall 20 is constructed as a retaining wall in which a wall 22 is hinged to a bottom plate 21 in the case of FIG. 1. In this case, the connection reinforcement 14 and the coupler 16 form a bottom plate 10 and the wall 20 are integrated with each other.

The wall 20 is constructed in such a manner that a plurality of wall segments are connected to each other in the construction direction (longitudinal direction) of the box structure.

In this case, the method of connecting the wall in the longitudinal direction is usually connected by various connecting means such as a shear key, a connecting bolt and a nut.

However, the most important point in connection of these longitudinal walls is whether or not the connection performance of the wall segments can be sufficiently secured and whether the workability can be improved by minimizing the number of wall segments installed in the manufacturing and transportation range.

First, in the case of the connection performance, since a plurality of wall segments are connected to each other even if a plurality of connection methods are used, a large number of connection parts can not be formed. Therefore, even if quality control is performed well, In practice, quality control is inevitably difficult, which means that in the longitudinal direction, a number of wall segments can not but have a limitation in structurally integrating one another.

In addition, a large number of wall segments are manufactured in advance in a factory. The closer the distance from the construction site to the construction site, the easier the transportation, the better the workability and the economical efficiency.

Normally, although the height of a plurality of segments is limited, a length of about 1m to 2m in the longitudinal direction is made with reference to about 3m to 5m, and a method of connecting them is adopted. However, as the length of one wall segment becomes longer, the weight becomes larger as the length of the wall segment becomes longer. Therefore, the size of the wall segment that can be transported and constructed is limited in consideration of transportation constraints and site construction.

In addition, when the wall segments are pre-cast, the connecting method with the bottom plate 10 adopts a hinge method. In this case, the wall segments are supported on the bottom plate so that the connection between the bottom plate and the wall segments is limited. The bending moment due to the self weight of the upper plate and the earth pressure can not but be concentrated on the wall segment and the bottom plate, so that the thickness of the wall segment is inevitably increased.

Although the connection between the bottom plate and the wall segment can be adopted in any way, the wall segment is made in a precast manner, so that the bottom plate and the method of strengthening the bolt are not disadvantageous in terms of cost and workability. I will not.

In addition, although the connection part is inevitably formed in the longitudinal connection with the wall segment, there is a problem in that it is not easy to secure the actual watertightness even if the connection part is actually used in the negative part.

Further, the top plate 30 can be installed by using a pre-casting method or a casting method such as a two-wall type, depending on the site conditions. In the precast upper plate 32, a prestress is introduced As shown in FIG. At this time, the precast upper plate 32 is installed on the upper part of the wall, and then the concrete is put in place by the concrete 33 placed on the site.
