Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spacer, particularly a spacer suitable for holding wire lath to be embedded in mortar for reinforcement when spraying mortar onto a slope or the like.

Conventionally, this type of spacer was made by crossing vertically and horizontally,
It is known that concrete products hold metal wires that serve as reinforcing bars. However, since some of them are formed in a ring shape, they tend to fall over and it is difficult to maintain the metal wires at regular intervals. In addition, some are designed to hold the metal wires in the cross direction at the intersection of the metal wires, but this spacer is adapted to the case where the metal wires in the cross direction are fixed by welding etc. The metal wires that are bent and tangled like wire lath are deformed,
In the case of relative movement, it is impossible to accommodate this, and therefore no holding work can be performed, and even if the metal wire is held forcibly, the spacer may be deformed or damaged as it attempts to restore its deformed state. There was a risk that the person would be forced to leave or be forced to leave.

The purpose of this invention is to be able to hold metal wires such as wire laths at a constant distance from a slope, etc., and to prevent metal wires such as wire laths from being bent and entwined and deformed or moving relative to each other. The object of the present invention is to provide a spacer that can be held reliably to prevent deformation, damage, detachment, etc., and that can improve workability.

In order to achieve the above object, the present invention includes a columnar body molded from synthetic resin, a leg portion at one end, and first and second metal wire holding portions at the other end of the columnar body.
The first metal wire holding part has an insertion opening that follows the holding groove on the opposite side from the leg part, and the holding groove is formed to have approximately the same diameter as the metal wire, and the second metal wire holding part has an insertion opening that follows the holding groove. The holding groove has an insertion opening following the holding groove in a direction perpendicular to the insertion opening of the first metal wire holding part, and the holding groove is formed to be wider than the diameter of the metal wire between the insertion opening side and the inner back side. ,
These first and second metal wire holding parts have stepped parts,
In addition, the holding grooves are arranged so that their axes intersect on an extended line.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. The spacer of the present invention is molded from synthetic resin, and as shown in FIGS. 1 to 3, a leg portion 2 is integrally provided at one end of a rectangular columnar body 1. This leg part 2 consists of leg pieces 3 that protrude symmetrically on both sides of the columnar body 1, and leg pieces 4 that protrude in the orthogonal direction from the middle part of each leg piece 3. An arcuate notch 5 is formed. A plate-shaped arm member 6 is integrally provided at the other end of the columnar body 1, and on both sides of this arm member 6, first and second metal wire holding portions 7, located on both sides of the columnar body 1, are provided. 8 are integrally provided. These first and second metal wire holding parts 7, 8
has a step, and the first metal wire holding portion 7 has a pair of holding pieces 10 and 11 protruding from a raised base 9.
Each retaining piece 10, 11 has a retaining groove 1 inside its base side.
2 is formed, and in this holding groove 12, an insertion opening 13 is formed by continuing on the side opposite to the leg part 2 and being inclined so that the facing surface gradually becomes wider as it reaches the open end side, and the inner end of the insertion opening 13 A locking portion 14 is formed in the. The holding groove 12 is formed to have an arcuate cross section so as to tightly hold the metal wire. Each holding piece 1
A cutout 15 having an arcuate cross section is formed along the holding groove 12 on the outside of the base of the holding piece 10, 11.
It is made easy to expand elastically. The second metal wire holding part 8 has a pair of holding pieces 16 from the arm member 6,
17 protrudes in a direction perpendicular to the holding pieces 10 and 11. A holding groove 18 is formed on the inner side of the base side of each holding piece 16, 17, and in this holding groove 18, the opposing surface continues outward in the direction perpendicular to the insertion port 13 and slopes so that it gradually becomes wider as it reaches the open end side. An insertion opening 19 is formed, and a locking portion 20 is formed at the inner end of the insertion opening 19. The holding groove 18 is the fourth
As is clear from the figure, the cross section is approximately elliptical with the long axis between the insertion port 19 side and the inner depth, that is,
It is formed to have a deeper depth than the holding groove 12, and the insertion port 19 is opened in a direction perpendicular to the insertion port 13. This second metal wire holding part 8 is formed into a bifurcated shape with a notch 21 formed in the center of both holding pieces 16 and 17, and can be easily expanded elastically by shortening each holding piece 16 and 17. That's what I do. These first and second metal wire holding parts 7 and 8 are arranged so that the axes of the respective holding grooves 12 and 18 intersect with each other at an acute angle of about 80 degrees on an extended line.

Next, how to use the present invention will be explained. Second
As shown in the figure, the wire lath 22 is placed along the slope 25 to be protected. Then, the holding groove 12 of the metal wire holding portion 7 is elastically fitted into the metal wire 23 of the wire lath 22 through the insertion opening 13. Next, the spacer is moved along the holding portion of the metal wire 23 to the side where it intersects with the metal wire 24, and the holding groove 18 of the second metal wire holding portion 8 is elastically inserted into the folded portion of the metal wire 23 through the insertion opening 19. It fits perfectly. At this time, the second metal wire holding section 8
As described above, the holding groove 18 has a substantially oval cross section and a deep depth, so even if the metal wire 23 is deformed during the bending process, the metal wire 23 can be easily removed by a worker riding on the wire lath 22. Even if 23 is deformed or moved relative to each other, it can be held securely. By attaching the spacer of the present invention to a desired location on the wire lath 22 in this manner, it is possible to maintain a constant distance between the wire lath 22 and the slope 25. Mortar is then sprayed onto the slope 25, and the wire lath 22 is buried in the mortar.

In addition, in the embodiment, the first metal wire holding part 7
Although the holding pieces 10 and 11 are made to be easily elastically deformed by the notches 15, the second metal wire holding part 8
The notch 21 may be formed in the middle part of the holding pieces 16 and 17 as shown in FIG. Similarly to the metal wire holding portion 7 of No. 1, notches may be formed on the outside of the base of the holding pieces 10 and 11 to facilitate elastic deformation.

As is clear from the above description, according to the present invention, the columnar body is molded from synthetic resin, has a leg portion at one end of the columnar body, and has first and second metal wire holding portions at the other end of the columnar body. , the first metal wire holding part has an insertion opening following the holding groove on the opposite side of the leg part, and the second metal wire holding part has an insertion opening following the holding groove in the insertion opening of the first metal wire holding part. The first and second metal wire holding parts have a step and are arranged so that the axes of both holding grooves intersect on the extension line. By elastically fitting the holding groove of the second metal wire holding portion onto the metal wire, the metal wire can be held at a constant interval on a slope or the like. Also the second
The holding groove of the metal wire holding part is formed to be wider depending on the diameter of the metal wire between the insertion opening side and the inner back side, so it is especially suitable for metal wires such as wire laths made by bending and entangling the metal wires. The metal wire can be held reliably in response to deformation or relative movement. Therefore, there are advantages such as being able to prevent deformation, damage, detachment, etc., and improve workability.
