Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for reinforcing steel columns, carbon fibers, and other filaments on pillars of buildings, railway viaducts, piers of three-dimensional roads or bridges, and other structures. The present invention relates to a device for winding.

[0002]

2. Description of the Related Art A bobbin on which a wire is wound is supported by a pair of vertically spaced support plates, and the pair of support plates is formed so as to be movable up and down. A winding device for moving the bobbin in an annular groove provided on each of the facing surfaces has been proposed (Japanese Patent Publication No. 7-112585).

[0003]

In the above-mentioned wrapping device, the structure is complicated because the bobbin moves along the annular groove of the pair of support plates, and the upper and lower support plates for supporting the bobbin are complicated. Is required, so the number of parts is large.

[0004] The present invention provides an apparatus for winding a linear material around a column of a structure, which can have a simple structure and reduce the number of parts.

[0005]

According to the present invention, there is provided an apparatus for winding a linear material around a column of a structure according to the present invention, comprising a guide, a lifting frame, and a supporting means. The guide has a plurality of guide posts disposed around the post. The elevating frame has a circular inner peripheral surface, and a space is formed inside the inner peripheral surface in the radial direction, and can be moved up and down along the guide. The elevating frame has a main portion having a cutout capable of receiving the support in the space by being moved in one direction in the horizontal direction, and an auxiliary portion which is fitted into the cutout of the main portion and is detachably attached to the main portion. And The supporting means fixedly supports a bobbin around which the filament material is wound, and a restraint that imparts resistance to the filament material drawn from the bobbin, and on the inner peripheral surface of the lifting frame. Along the circumference.

The lifting frame is supported by a plurality of guide posts of the guide so as to be able to move up and down. At this time, the auxiliary part of the lifting frame is separated from the main part. Then, move the lifting frame together with the guide in one horizontal direction,
The column is received in the space of the lifting frame, and the auxiliary part is attached to the main part. When the bobbin and the restraint are moved in the circumferential direction by the support means while the lifting frame is raised along the guide, the wire is wound around the support at a required pitch while maintaining a constant tension. After winding the wire,
If necessary, a mortar or other coating material is sprayed on the column, or a mold is placed around the column to inject the coating material.

[0007] Since the lifting frame moves up and down along the guide and the supporting means fixedly supporting the bobbin and the restraint moves in the circumferential direction along the inner peripheral surface of the lifting frame, the entire apparatus is constructed. The structure is simple and the number of parts can be reduced.

[0008] Since the lifting frame has a circular inner peripheral surface and has a structure in which the column is received in a space radially inward of the inner peripheral surface, the column has a circular or square or rectangular cross section. Even in the case of a rectangular shape, the wire can be wound around the pillar without any trouble. In addition, in order to wrap the wire around the strut in a state where resistance is given to the wire by the restraint,
A constant tension can be introduced into the wire and a loose winding is possible.

The number of turns and the pitch can be arbitrarily selected by adjusting the elevating speed of the elevating frame and the moving speed of the support means in the circumferential direction. In this case, since any of the speeds can be automatically controlled, efficient construction can be performed with high accuracy.

In one preferred embodiment, the guide is
It is movable on a pair of rails disposed across the support, and the cutout of the main body portion of the elevating frame moves in a direction substantially orthogonal to the moving direction of the guide moving on the rail. It is open.

The guide post of the guide can be installed around the support and the lifting frame can be supported on the guide post so as to be able to move up and down. However, in order to improve the workability, the guide post is assembled at a position where the support is removed from the support and the lift is lowered. It is better to have the frame supported and carry the whole to the work site. A pair of rails and a guide movable on these rails are one means for that purpose. Since the cut of the main body of the lifting frame is opened in a direction substantially perpendicular to the direction of movement of the guide, the size of the cut can be kept to a minimum.

When the guide is movable on a pair of rails, the main body of the lifting frame has another cut, and the lifting frame fits into the another cut and is detachably attached to the main body. Can have another auxiliary part. The another cut is formed to allow the guide to move in the one direction across the support when the another auxiliary part is separated from the main part, and the guide is moved in the one direction. With this, the column is brought out of the space.

For example, when two piers are arranged,
After winding a wire on one pier and then trying to wind a wire on another pier, if there is only one cut in the elevating frame, the strut must be brought out of the space from this cut. No. With the strut outside, the cut of the lifting frame of the winding device is in the opposite direction to the other pier. Therefore, once the entire apparatus is disassembled, it is necessary to reassemble the elevating frame so that the cut end of the elevating frame is directed to another pier. By providing two cuts in the lifting frame, such inconvenience can be solved, and as a result, the workability in winding the wire material around a plurality of columns can be greatly improved.

In another preferred embodiment, the guide is supported on a carriage equipped with a crawler.

In order to improve the workability, a guide post is assembled at a position off the support to support the lifting frame,
It is another way to carry the whole thing to the work site.

It is preferable that the supporting means further includes a boom extending substantially in a vertical direction, and a sheave for guiding the linear material movable along the boom. Thereby, when the lift frame reaches the upper limit or the lower limit of the lift, the wire member is guided further upward or downward.

Although the range of elevation of the elevating frame is limited by the height of the guide, the pier has a higher girder portion,
Since there is a base portion lower than the ground, if the lifting frame moves up and down within the range of the height of the guide, it is impossible to wind a wire material around the girder portion or the base portion. This can be dealt with by further providing a boom and a sheave.

The four guide posts are arranged around the column so that the shape in plan view is square or rectangular. The guide posts are preferably movable on rails or mounted on crawlers.

The lifting frame may be in the form of an annular ring having a circular inner peripheral surface. A cut is made in a portion of the annular ring and when the lifting frame is moved laterally with respect to the post, the cut passes through the post and positions the post in a space inside the inner peripheral surface. Preferably another cut is provided on the opposite side of the cut. The lifting frame is attached to sprockets at four locations above and four locations below the guide, respectively, and is coupled to four chains extending over these sprockets to be lifted and lowered.

The supporting means has an annular turning ring movable in the inner peripheral surface of the elevating frame, and can be formed by attaching a bobbin and a restraint to the turning ring. The supporting means further comprises an arc-shaped turning member. It can be formed by attaching a bobbin and a restraint to a member.
