Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is intended to easily insert a transverse bar through a crotch of a yoke when a tubular reinforced concrete wall such as a silo is constructed by a sliding formwork method. And an apparatus for assembling a transverse streak carried out using the apparatus. [Conventional technology and its problems] Conventionally, when constructing a tubular reinforced concrete wall body by a sliding formwork method, assembling the horizontal bar for the wall body, the reinforcing bar for the horizontal bar that has been processed into a predetermined shape in advance along the wall body. Since it is inserted into a narrow gap between the crotch of a plurality of provided yokes and the vertical line of the wall body and moved to a predetermined position, at least three rebar workers are required even if the rebar is thin. Is. In recent years, an example of an apparatus for moving the tip end of the coil reinforcing bar along a guide rail provided penetrating the inseam of the yoke can be seen, but the coil reinforcing bar is more expensive than ordinary steel bars, and the tubular wall body is A large number of composite silos and the like require as many sets of devices as the number of tubular walls, which is uneconomical. The present invention has been made in view of such a situation, and an object thereof is to provide a simple device and be able to assemble the horizontal bar reliably and promptly by a small number of reinforcing workers. [Means for Solving the Problems] The present invention has been made in order to achieve the above-mentioned object, and in the construction of a tubular reinforced concrete wall body using the sliding formwork method, the sliding formwork has an arc shape. The hanger rails 10 which are arranged at regular intervals in the longitudinal direction of the hanger rail and which extend through the crotch of the yoke 7 projecting above the sliding formwork and which are provided along the upper part of the wall body form an annular planar shape. A plurality of hanger 11 is provided at the lower end of the bar, and a plurality of clamps 12 for temporarily fixing reinforcing bars are provided.
The loop runner 1 is hung by a circular hanger rail 10 by means of a ring and has the same circumferential length as the hanger rail 10.
3 and the side of the loop runner in contact with the loop runner 1
The gist of the present invention is to include a rotor 15 such as a roller or a gear that interlocks with the rotation of the main shaft of the electric motor 14 that moves the motor 3 in the circumferential direction. [Operation] In order to assemble the horizontal bars, the reinforcing bars that have been processed into a predetermined shape are placed horizontally on the work floor near the wall, and the tip of the reinforcing bars is fixed to the clamp 12 at the lower end of the hanger 11, and the reinforcing bars are fixed. If you push the rear part of, the tip moves along with the hanger 11 along the hanger rail 10 and goes under the crotch of the nearest yoke. , After fixing the rear end part with other multiple clamps and moving the rebar to the desired position, push it against the vertical bar to make it adhere, and while tightening and fixing the intersection with the vertical bar with iron wire etc. Remove the clamp.
In this way, the horizontal lines are assembled. This series of work can be carried out by one reinforcing bar worker. [Embodiment] The present invention will be described below based on the illustrated embodiment. In FIG. 1, 1 is wall concrete being constructed by a sliding formwork method, 2 is horizontal wall reinforcement for wall, 3 is horizontal reinforcement 2 for wall and sliding formwork provided along the wall, 4 Is a work floor connected to the upper side of the formwork, 5 is a vertical line extending from the inside of the wall, 7 is a yoke fixed to the sliding formwork 3, 8 is a rod built vertically from the lower end of the wall, 9 is this rod 8
Shown is a center hole type jack which is supported and raised by 10 and 10 is a hanger rail of the device according to the present invention. 6
Reference symbol a indicates a reinforcing bar for the horizontal bar suspended by the clip 12 and the hanger 11 on the hanger rail, and 6b indicates a state where the reinforcing bar is tightly fixed to the vertical bar. The hanger rail 10
Is provided so as to pass through the crotch of the yoke along the upper side of the wall body and is joined and supported by the yoke. Hanger 11 Hanger is rail 1
The wheels 11a incorporated inside the 0 easily travel in the length direction of the hanger rail (hereinafter referred to as the rail direction),
You can move. Since the sandwiching metal fitting 12 for temporarily fixing the reinforcing bar and the like is suspended by the pin 11b at the lower end of the hanger 11, it can freely rotate in a plane orthogonal to the rail direction. The above-mentioned hanger rail 10, a plurality of clip fittings 12, wheel 1
In order to assemble a horizontal bar using a device composed of a hanger 11 equipped with 1a, a reinforcing bar preliminarily processed into a predetermined shape is placed horizontally on the work floor near the wall body, and the tip of the reinforcing bar is attached to the hanger 11. By fixing it to the clamp 12 at the lower end and pushing the rear part of the reinforcing bar, this tip moves with the hanger 11 along the hanger rail 10 and goes through the crotch of the nearest yoke,
After further pulling this tip part and passing through the inseam of the next yoke, sequentially fix the middle part and the rear end part of the reinforcing bar with a plurality of other clamps and move the reinforcing bar to the desired position,
The metal fittings are sequentially removed while pressing the vertical bars to make them adhere to each other and tightly fixing the crossing section with the vertical bars using an iron wire or the like, but the above series of operations can be carried out by a single reinforcing bar worker. FIG. 3 shows a different embodiment. In FIG. 3, reference numeral 10 denotes a circumferential hanger rail provided through the crotch of the yoke along the upper side of the cylindrical wall body, and 13 is made of strip steel and is composed of a plurality of hangers 11. A loop runner is shown that is suspended and has a plurality of clip members 12 joined to its lower end.
The loop runner 13 is provided by a roller type rotor 15 that is in close contact with the loop runner portion and is rotated by the electric motor 14.
Automatically moves below the hanger rails 10. An apparatus is used which is composed of the circular hanger rail 10, the loop runner 13, a plurality of hangers 11, the sandwiching metal 12 and the electric motor 14 for automatically moving the loop runner in the rail direction, and the rotor 15 connected to the electric motor 14. In order to assemble the horizontal reinforcing bar, the reinforcing bar preliminarily processed into a predetermined shape is placed horizontally on the work floor near the wall, and the tip of the reinforcing bar is sandwiched between the metal fittings 1
When fixed to 2, the electric motor 14 is energized, the rotor 15 is rotated, and the loop runner 13 is laterally moved in conjunction with this, the reinforcing bar is pulled in from the tip portion to the inseam of the yoke, and a plurality of other nips are sequentially inserted. The metal fitting 12 fixes the middle portion and the rear end portion of the reinforcing bar, and when the reinforcing bar moves to a desired position, the electric motor 14 is stopped and the loop runner 13 is stopped, and the reinforcing bar is pushed to be closely attached to the vertical bar. While tightly fixing the crossing portion with the streak using a steel wire or the like, the sandwiching metal fitting 12 is sequentially removed. For example, when the horizontal stirrup of one circumference is assembled with four rebars,
Since the four iron wires can be simultaneously moved to desired positions by power, it is possible to save a great deal of labor. The present invention can be applied not only to a cylindrical wall body such as a silo but also to a case where a polygonal tubular wall body is constructed by a sliding formwork method. [Effects of the Invention] According to the present invention, therefore, the horizontal bar assembly work, which conventionally required a team of three or more workers, can be performed by one person, and the vertical bar falls to the outside of the wall body. It has a number of advantages such as the ability to prevent
