Abstract

PURPOSE:To obtain a beautiful grid frame which can be easily processed and assembled by a method in which an U-shaped continuous steel wire-formwork made of one metal wire is set in a grid form on slope and concrete is placed to form a cast-in-place concrete grid frame. CONSTITUTION:Continuous steel wire-formworks 6a are set bilaterally at intervals in the vertical direction of slope 7. T-shaped anchors are driven into the slope 7 from the inside of the formwork 6a by hooking T-shaped anchors on both ends of an upper horizontal lever 8 and coupled with a trench formwork edge plate 5 on upper both ends of the formworks 6a to fix it to the slope 7. In the same way even for the lateral direction, continuous steel wire- formworks 6b are set in a grid form with the formworks 6a, and a reinforcing plate 14 consisting of joint plates 13 of bent plates 12 with many air holes 11 is set on the joint outside of the formworks 6a and 6b. The plates 13 are coupled with the edge plate 5 by hook 16 and cement mortar is packed into the formworks 6a and 6b and the late 14 and hardened for reinforcement.

Description

[Detailed Description of the Invention] Industrial Field of Application This invention uses continuous steel wire formwork and continuous steel wire formwork for constructing concrete lattice frames on nine sides rising from roads, residential areas, etc. This is related to the construction method used.

Conventional technology In the past, when reinforcing a slope in civil engineering work, precast concrete members were attached in a lattice pattern, or formwork was assembled on the slope in a lattice pattern and reinforcing bars were placed inside. This is a concrete lattice frame filled with cement concrete or mortar and cast on site. However, when using formwork, it takes a lot of effort to assemble and remove the formwork, so in recent years, square or circular coil bars have been arranged in a lattice pattern on the slope surface, and cement concrete or mortar can be used without a formwork. A construction method for spraying has also been developed.

Problems to be Solved by the Invention However, when cement concrete or mortar is sprayed onto coil bars without a frame, the cement concrete or mortar that flows out on both sides of the coil bars must be cut when the coil bars are in a semi-hardened state. However, there were drawbacks such as the time required for finishing and the appearance of the hardened concrete lattice frame was poor.

In order to solve these problems, the present invention has developed a continuous steel wire formwork formed into a U-shape using one continuous metal wire, and a continuous steel wire formwork that is assembled on a slope in a lattice pattern. This is a construction method in which a concrete lattice frame is cast on-site while being filled with concrete or mortar, and the continuous steel wire formwork is easy to process, requires no effort to assemble parts, and the finish of the concrete lattice frame is aesthetically pleasing. This is a characteristic feature.

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

A U-shaped frame in which a metal wire 1 such as a steel wire or iron wire is sequentially bent into a parallel meandering shape 2 to form a band 3 that continues in the left and right direction, and the front and rear ends of the band 3 are bent upward. A large number of continuous steel wire forms 6 of appropriate height and length are formed on the upper edge of the groove 4, and continuous steel wire forms 6a are placed vertically on the slope surface 7 at appropriate intervals on the left and right sides. A T-shaped anchor 10 with hooks 9 provided at both ends of the upper transverse rod 8 is placed on the slope surface 7 within the continuous steel wire form 6a.
The hooks 9 at both ends of the upper horizontal rod 8 are hooked to the groove frame edge plates 5 at the upper ends of both sides of the continuous steel wire formwork 6a, and the continuous steel wire form is inserted in the horizontal direction at the interval between the continuous steel wire formworks 6a in the vertical direction. Frame 6
b, and both ends of the continuous steel wire formwork 6b are joined to both sides of the vertical continuous steel wire formwork 6a in a lattice pattern, and the T-shaped anchors 1o are attached to the slope surface 7 within the horizontal continuous steel wire formwork 6b. The hooks 9 at both ends of the upper horizontal rod 8 are hooked to the edge plate 5 of the grooved formwork, and a large number of air vent holes 11 are formed at the same height as the continuous steel wire formwork 6.
The reinforcing plate 14, which is made by bending both ends of the perforated plate 12 in the same direction at an angle of about 45 degrees to form the joint plate 13, is connected to the continuous steel wire form 6a in the vertical direction and the continuous steel wire form in the horizontal direction. Joint plates 1 at both ends of each reinforcing plate 14 are arranged on the outer surface of the joint with 6b.
3 and continuous steel wire formwork 6a.

Continuous steel wire formwork 6a assembled in a lattice shape by locking the grooved frame edge plate 5 of 6b with the upper end hook 16 of the hooked anchor 15 driven into the slope surface 7 within the continuous steel wire formworks 6a, 6b, 6
This is made by filling and hardening cement concrete or mortar inside b and the reinforcing plate 14. In addition, 17 in the figure
indicates reinforcing bars.

Functions and Effects The continuous steel wire form 6 of the first invention sequentially bends the metal wire 1 with a diameter of 1 to 3 mm into a parallel serpentine shape 2 to form a band 3, and then bends the metal wire 1 upward from the position where the front and middle are divided into three equal parts. A U-shaped frame 4 is formed by bending the U-shaped frame 4, and a grooved frame edge plate 5 is fitted in order to align the upper ends of the U-shaped frame 4. The gap between the metal wires 1 bent into a parallel meandering shape 2 is about 5 to 10 mm, and the cement concrete or mortar filled inside gradually flows out from the gap between the metal wires 1 and the metal wires 1. It is coated and hardened, so it will not flow out in a mountain shape like when cement concrete or mortar is sprayed onto the coil wire.

Since the continuous steel wire form 6 is made of metal wire 1 such as steel wire or iron wire, it is easy to process, lightweight, and has good transportability and workability. In the slope reinforcement method of the second invention, in which a concrete lattice frame is cast in situ on the slope surface 7 using continuous steel wire formwork 6, continuous steel wire formwork 6 is placed on the slope surface 7 in the vertical direction.
After placing reinforcing bars 17 in the continuous steel wire form 6a, the T-shaped anchor 10 is driven into the slope surface from within the continuous steel wire form 6a. The continuous steel wire form 6a is attached to the slope surface 7 by hooking the hooks 9 at both ends of the upper horizontal rod 8 to the groove form frame edge plates 5 at the upper ends of both sides of the continuous steel wire form, and then the left and right continuous steel Linear frame 6a
Continuous steel wire forms 6b are arranged in the horizontal direction at intervals of and joined to both sides of the vertical continuous steel wire form 6a in a grid pattern,
After arranging reinforcing bars 17 inside, T-shaped anchors 1o are driven in, and a horizontal continuous steel wire form 6b is attached to the slope surface 7.
A reinforcing plate 14 is arranged on the outer surface of the joint between the continuous steel wire forms 6a and 6b in the vertical and horizontal directions, and an anchor 15 with a hook is driven into the slope surface 7, and the upper end hook 16 is used to attach the reinforcing plate 14 to the continuous steel wire form. 6a and 6b, and a continuous steel wire formwork 6a is attached to the slope surface 7.

6b are attached in a grid pattern, into which cement concrete or mortar is poured.

The continuous steel wire forms 6a and 6b are formed by bending the metal wire 1 into a parallel serpentine shape 2, and freely adapt to the unevenness of the slope surface 7 while adhering closely to the slope surface 7. The purpose can be achieved, and some of the cement concrete and mortar poured inside will flow out from the gap between the metal wires 10, but it is best to finish by smoothing it with an appropriate tool such as a plastering trowel before it hardens. A square, aesthetically pleasing concrete lattice frame can be constructed on the slope 7, and there is no need to cut out spilled cement concrete or mortar, streamlining construction and reinforcing the slope as a strong concrete structure. etc., the above-mentioned remarkable effects can be achieved.
