Abstract

PURPOSE:To raise the efficiency of construction work by a method in which auxiliary reinforcing bars set around coil bar are coupled by inverted V-shaped couplers, a formwork is attached to L-shaped hooks provided on both sides of the coupled portion, and cement mortar is poured into the formwork. CONSTITUTION:A round coil bar 2a is extended vertically on a slope 1, and a round coil bar 2b extended sidewards is set crossly and fixed to the slope 1 by anchoring bars. Three sets of auxiliary reinforcing bars 9 coupled to the inside of left, right, and middle circles of several sets of couplers 8 are welded to coil bars 2a and 2b inserted from above. The vertical hole of a formwork 10 is fitted on left- and right-handed L-shaped hooks formed on both ends of the coupler 8 to form left- and right-handed formworks 10 which are erected. Cement mortar is poured into the formworks 10 and hardened, and the formworks 10 are removed. The efficiency of the construction work can thus be raised.

Description

DETAILED DESCRIPTION OF THE INVENTION The invention with its industrial application relates to a method of constructing a concrete lattice frame for reinforcing a slope.

Conventional technology In the past, when constructing a concrete lattice frame for reinforcement on a slope, reinforcing frame members made of precast concrete members or steel members were placed on the slope and assembled. In order to save labor during construction, coil reinforcements are arranged in a lattice pattern on the slope, and mortar is sprayed using a formless frame.

Problems to be Solved by the Invention However, when coiled reinforcement is arranged on a slope, reinforcing reinforcing bars are placed on the top and both sides of the coiled reinforcement and tied together with binding bars, which makes the binding work time-consuming. In addition, when concrete is sprayed onto the coil reinforcement, the concrete flows out on both sides, and the concrete has to be cut in a half-hardened state, which requires time and effort.

In order to solve these problems, the present invention uses an inverted V-shaped locking tool to lock the auxiliary reinforcing bars placed around the outer circumference of the coiled reinforcing bars with an inverted V-shaped locking tool, without tying them with binding bars. This is a method of constructing a concrete lattice frame on a slope by installing L-shaped hooks on both sides of the tool and pouring mortar into the formwork while attaching the formwork. The present invention is characterized in that it is easy to connect the reinforcing bars and the auxiliary reinforcing bars, and the sprayed mortar does not flow out, making it possible to streamline the construction of concrete lattice frames for reinforcing slope surfaces.

A foolproof way to solve problems Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

A large number of circular coiled wires 2a are arranged on the slope surface 1 at appropriate intervals on the left and right while extending in the vertical direction, and oval shaped coiled wires 2b are extended in the horizontal direction and intersect with the coiled wires 2a in a lattice pattern. While being placed on the slope surface 1, the left and right sloped rods 4 are latched to the slope surface 1 with anchor reinforcements, and the left and right sloped rods 4, 4 are installed diagonally downward to the left and right from the central circular arc portion 3a that fits with the auxiliary reinforcing bars.
, 4, with the openings facing each other at the lower positions of the left and right circular arc parts 3.
b, 3c are curved and arm rods are protruded diagonally upward from the outer surfaces of the left and right circular arc parts 3b, 3c to form a left-right type hook 5 for locking the formwork.
a, 5b are curved to receive the lower end of the formwork at the lower end of the left and right inclined rods 4, 4.

6b are protruded and are vertically opposed to the left and right type hooks 5a and 5b, and the left and right type hooks 5a and 5b, and the left and right type receivers 6a and 6b.
A notch 7 for driving is provided on the lower surface of the auxiliary reinforcing bar, and a large number of auxiliary reinforcing bar locking tools 8 are formed, and a central circular arc portion 3a of the auxiliary reinforcing bar fastening tool 8 is provided.
, while fitting the auxiliary reinforcing bars 9 into the left and right circular arc parts 3b, 3C, an arbitrary number of auxiliary reinforcing bars 9 are engaged with the auxiliary reinforcing bars 9, and the coiled reinforcing bars 2a, 2b are arranged in a grid pattern on the slope surface 1. Three sets of auxiliary reinforcing bars 9 locked with auxiliary reinforcing bars 8 are inserted from the top surface, and the auxiliary reinforcing bars 9 are crimped on the top surface and both sides of the coil bar.
Opposed left and right hooks 5 a of each auxiliary reinforcing bar locking device 8
+ 5 b and left and right mold receivers 6a and 6b with left and right formwork 10
．． 10, and mortar 11 is placed in the left and right formworks 10110. In addition, 12 in the figure
indicates a vertical hole in the formwork.

Effects: The coil strips 2a are arranged vertically on the slope 1, and the coil strips 2a are arranged vertically on the slope 1.
The coiled wires 2b are arranged in the horizontal direction so as to intersect with the curved line a, and the coiled wires 2a and 2b are arranged in a lattice pattern on the slope surface 2, while being locked by anchor wires. Then, the central circular arc portion 3a and the left and right circular arc portions 3 of several sets of auxiliary reinforcing bar locking devices 8
b, 3 sets of auxiliary reinforcing bars 9 locked in 3c are inserted upward into the vertical coil bars 2a and the horizontal coil bars 2b, and the auxiliary reinforcing bars 9 are crimped on the top and both sides of the coil bars with one touch. In this case, long auxiliary reinforcing bars 9 are used for the vertical coiled reinforcing bars 2a, and short auxiliary reinforcing bars 9 are used for the horizontal coiled reinforcing bars 2b. On both sides of each auxiliary reinforcing bar locking device 8, the left and right formworks 10.10 are formed with vertical holes 12 to be fitted with the left and right hooks 5a and 5b, and the vertical holes 12 are fitted into the left and right hooks 5a and 5b. After that, shift the left and right formworks 10.10 downward to stop the lower ends of the left and right formworks 10.10 in the left and right mold supports 6a and 6b, and stand the left and right formworks 10.10 on both sides of the coil strips 2a and 2b arranged in a grid pattern. The mortar 11 is then poured into the interior. After the mortar 11 has hardened, left and right hooks 5a and 5b and left and right mold receivers 6 protrude outside the left and right formworks 10 and 10.
While hitting a and 6b with a hammer, insert the left and right formwork 1.
0.10 is removed.

Therefore, in the construction method of the present invention, the coil reinforcement 2a,
Since the auxiliary reinforcing bar locking device 8 is used to connect the auxiliary reinforcing bar 2b and the auxiliary reinforcing bar 9, the hooks 5a, sb of the auxiliary reinforcing bar locking device 8 can be left and right without requiring any effort.

Since the left and right formwork 10°10 can be installed using the left and right mold supports 6a and 6b, a square and aesthetically pleasing concrete lattice frame can be constructed on the slope without mortar flowing out.
This provides the remarkable effects described above.
