Abstract

(57) [Summary] [Purpose] A legal framework structure that enables simple, safe, and robust construction of legal frameworks on the surface of embankments and slopes. [Structure] A vertical frame is provided with a core wire inside, and the end of the core wire is 6-1.
It is a secondary product made of concrete of a fixed length and protruding by 6 cm, and it is assumed that the secondary products are successively connected in the height direction of the slope to be continuous, and a plurality of the vertical frames are juxtaposed at regular intervals to be adjacent to each other. The horizontal frame for connecting the frames is characterized in that it is constructed by mortar spraying after assembling and assembling the connecting portions in the horizontal direction of the vertical frame.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a legal framework structure constructed in civil engineering work.

[0002]

[Prior art]

 Slope protection work is performed as earth retaining work on the surface of embankments such as levees and slopes of cut mountains.This involves hitting a number of anchor bars at regular intervals at the site and at the same time attaching each anchor bar. The rebar is assembled by connecting it with the rebar, and then mortar is sprayed on the spot.

[0003]

[Problems to be solved by the device]

 In the above work, there are problems that it takes a long period of time and costs increase because all the steps from driving the anchor bar to assembling the bar are carried out on site. It is also considered that the law block produced in a certain shape is transported to the site and anchored, but there are various problems in the transportation of the block and the placement on the site. The present invention is intended to partially solve the above problems.

[0004]

[Means for Solving the Problems]

 The vertical frame of the present invention is a secondary product made of concrete of a certain length in which a core wire has been previously put inside the factory and the end of the core wire is projected by 6 to 16 cm, which are sequentially connected in the height direction of the slope. The horizontal frame connecting the adjacent vertical frames by arranging a plurality of the vertical frames in parallel at a fixed interval after assembling the connecting points in the horizontal direction of the vertical frame, It is composed by spraying mortar. The vertical frame having a width of 10 cm to 20 cm and a length of 70 cm to 190 cm is excellent in handling and workability.

[0005]

[Operation] The vertical frames are arranged side by side at regular intervals in the height direction of the slope, and the core wires protruding upward are joined to each other, and the anchor is driven into the ground at that location. And fix it on the slope. Next, a horizontal frame for connecting the vertical frames arranged side by side is formed by assembling reinforcing bars between the connection points of the vertical frames and then spraying the part with mortar.

【Example】

 FIG. 1 is a perspective view of a vertical frame 1 used in the present invention, which is a secondary product made of concrete and is manufactured at a factory. Reference numeral 2 is a core wire projecting from the main body by about 6 to 16 cm, and is used for joining as described below. The vertical frame 1 is a rectangle having a length of 10 cm to 20 cm and a length 1 of 70 cm to 190 cm, which is excellent in handling and workability.

FIG. 2 is a construction state diagram, 3 is a slope, and the vertical frames 1, 1 ... The joining is performed by joining the core wires 2 protruding from the longitudinal edge of the vertical frame body to each other. Further, the adjacent vertical frames at the joints of the cores are connected to each other by another core 4 and an anchor 5 of a certain length is driven into the soil at this portion to secure the whole structure. Is done as is done.

Then, when the above work is completed, the mortar spraying work is performed with the core wire 4 of the horizontal frame as the center, and the mortar spraying is performed by the conventional method. The horizontal frame 6 is formed by spraying the entire mortar including the joints of the provided vertical frames with a constant thickness.

[0009]

[Effect of device]

 The present invention is implemented as described above, in which only a vertical frame having a certain standard size is manufactured in a factory, and this is transported to the site and joined at a constant interval, and the vertical frame has a length of 70 cm to 190 cm. Since it is a rod body, it is easy to transport and handle, and the vertical frame can be easily formed on site by using the protruding core wire.

On the other hand, in the horizontal frame, another core wire is used to connect another core wire connecting part and another adjacent core wire connecting part of the vertical frame, and the part is anchored to fix the whole frame. At the same time, since the mortar is sprayed to the slope centering on each core wire, including the joints between the horizontal and vertical frames, the adhesion with the slope is sufficiently ensured and the overall stability is stable. It will have a strong legal framework.
