Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pre-

The present invention relates to a pre-cast panel connection structure of a large double wall,

It is easier to connect the connections of large and double wall inner and outer precast panels used to build thick and high concrete retaining walls and the vertical joints where these double wall and double wall meet. To a pre-cast panel connection structure of a large double wall which can improve workability and reduce a construction cost.

DOUBLE-WALL, which is generally applied to the construction of concrete retaining walls, is a structure in which reinforcing steel reinforcing materials such as truss joints are embedded and arranged at regular intervals inside a pair of inner and outer precast panels of 6-7 cm thickness .

The double wall is formed by embedding one end of the connecting stiffener in one precast panel and then inverting it using an inverter so that the other end of the connecting stiffener is embedded in the unreinforced concrete of the opposite panel It is solidified and completed in one body.

The reinforced concrete reinforced concrete reinforcement is reinforced in the hollow part between the inner and outer precast panels, and then the concrete is poured into the reinforced concrete. When cured, it has the same structure and performance as the cast concrete slabs of the same thickness, and is mainly applied to the bearing walls of residential buildings and retaining walls of underground structures. In Korea, the number of attempts to apply doublewall to the construction of large concrete retaining walls in wastewater treatment plants such as underground water storage facilities and semiconductor factories has been increasing.

Therefore, in order to improve the workability, to shorten the construction period, and to reduce the construction cost from the production at the factory to the completion of the retaining walls at the factory, the large double walls are used for connection of inner and outer precast panels, Many researches have been made on a connection method that can more easily make the reinforcing joining of the vertical joint between the double walls.

In one example, in connecting a large double wall and a double wall continuously,

1, a large double wall made up of inner and outer precast panels 21 is assembled in the field, and a wire mesh (not shown) is prepared in advance in the inner side of the vertical joining portion of the adjacent large wall precast panel 21, (25) are continuously inserted to reinforce the break of the reinforcing bars between the large double wall and the double wall by lap joints, and then the concrete is poured and filled in the space between the inner and outer precast panels (21) .

However, since such a conventional large double wall must undergo a process in which a worker inserts the wire mesh 25 into each narrow gap of the vertically joined portion of the continuously assembled inner and outer precast panel 21, And it takes a long time, which is a major cause of a significant decrease in productivity.

Also, in order to combine the inner and outer precast panels during manufacture, transport, and assembly in such a way that they do not separate when handling, and to withstand the side pressure at the time of pouring concrete after assembling, Since a lightweight steel truss-linkage reinforcement is installed between the precast panels, one end of the connecting stiffener is embedded in one of the precast panels at the time of fabrication, and then the inverted stiffener is turned upside down with the inverters, Since the other preheating member is hardened in a state where the other end of the one connecting stiffener is buried and the outer precast panel is integrated,

The manufacturing process is very complicated, and concrete curing is time-consuming, and high production costs are required.

The present invention has been made in view of the above-described problems of the conventional large-size double wall pre-cast panel connection structure,

It is an object of the present invention to improve the pre-cast panel connection structure of a large double wall,

It is possible to more easily connect the inner and outer precast panels of the large double wall and the vertical joint between the double wall and the double wall to secure the joint performance of the reinforcing bar to improve the workability and reduce the construction cost To be able to.

To this end,

In the present invention, a joint having a step in each of inner and outer precast panels constituting a double wall is embedded in a wire mesh formed at both left and right ends, respectively,
In the large double wall assembly, in a state in which one end portion of the wire mesh protruding left and right from the adjacent precast panel is overlapped with the other side end portion of the adjacent another wire mesh due to the step difference,
Due to the concrete being filled, the adjacent double walls are firmly integrated with each other,

delete

The workability can be improved, the construction period can be shortened and the construction cost can be greatly reduced,

When the inner and outer precast panels are manufactured, the connecting stiffener is poured into concrete with the use of concrete instead of the lightweight steel truss, and the outer precast panel and the connecting stiffener are simultaneously poured,

It is not necessary to first fabricate and invert one side precast panel,
The connecting stiffener is hardened in a state in which the connecting stiffener is firstly embedded in one precast panel for the installation of the connecting stiffener and then the other end of the connecting stiffener is buried in the unreinforced concrete of the opposite precast panel, Without this,

It is possible to more easily and quickly connect the internal and external precast panels and the connecting stiffener integrally to greatly reduce the installation cost.

The pre-cast panel connection structure of the large double wall of the present invention,
In the large double wall assembly, in the adjacent pre-cast panel, one end of the wire mesh projected to the left and the right is overlapped on the other side edge of the adjacent another wire mesh due to the step difference, So that they are firmly integrated with each other,

The workability can be improved, the construction period can be shortened and the construction cost can be greatly reduced,

The inner and outer precast panels and the connecting stiffeners are simultaneously cast into concrete at the same time without having to pre-fabricate and invert the one precast panel at the time of manufacturing the inner and outer precast panels,

It is possible to connect the internal and external precast panels more simply and quickly, thereby greatly reducing the cost of the construction.
