Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lath with a force skeleton for holding a mortar on a base by tensioning the base on which the mortar is applied and reinforcing the mortar to prevent cracks from occurring.

[0002]

2. Description of the Related Art When a lath with a force bone, which is provided with a force bone orthogonal to a lath, is stretched on a base on which mortar is applied, the applied mortar is held on the base. The solidified mortar can be reinforced to prevent the occurrence of cracks.

[0003] However, since the conventional braced lath is stretched almost flatly on the base, it cannot be said that the effect of holding and reinforcing the mortar is necessarily sufficient.

In order to improve these points, if the force bone in one direction of the force bones in two directions orthogonal to each other in the lath with force bone is formed so as to be slightly floating from the lath surface, The lath can be maintained in a state of being slightly floated from the base by tensioning the force bones in one direction so as to abut on the base over the entire length. However, since the force bones in the one direction contact the base over the entire length and the portion of the lath along the force bones is close to the base, the effect of reinforcing the mortar and preventing cracks from occurring in the portion along the force bones is not sufficient. It was sufficient, and the effect of reinforcement and prevention of cracks was not sufficient as a whole.

The present invention has been made in view of the above-mentioned problems existing in the prior art, and its purpose is to make the lath and the braced force almost uniform by stretching it on the base to which mortar is applied. It is generally held in a state of floating from the base,
Another object of the present invention is to provide a lamina with a force bone that can effectively reinforce the entire painted mortar and effectively prevent the occurrence of cracks.

[0006]

Means for Solving the Problems In the lath with a force bone of the present invention which achieves the above object, two or more first force bones that do not intersect with each other and two or more second force bones that do not intersect with each other are provided. Is a lath with force bones attached to a lath in a state where the first force bones and the second force bones intersect with each other, and all or part of an intersection portion of the first force bones and the second force bones. In, the first force bone and the second force bone both project from one surface of the lath at a substantially constant height to form a projecting intersection, and each projecting intersection contacts a flat surface. In the case where the lath and the first force bone and the second force bone are held, the lath and the first force bone are held in a state of being floated from the flat surface thereof except for the projecting intersection.

When each projecting intersection is brought into contact with the base on which the mortar is applied and the lath with a force bone is stretched over the base, both the first force bone and the second force bone are at the protrusion intersecting point. Since it protrudes from one surface at a substantially constant height, both the lath and the first force bone and the second force bone are held in a state of being floated from the base except for the protruding intersection.

Therefore, when mortar is applied to the base and the lath with strength bones is embedded in the mortar, the lath and the first strength bone and the second strength strength except for the protruding intersection are located at the middle position of the thickness of the mortar. Since the bone can be located, the entire mortar is effectively reinforced by the lath and the first and second force bones, respectively. Therefore, the occurrence of cracks in the mortar can be very effectively prevented.

By fixing the first dynamic bone and / or the second dynamic bone to the substrate by stapling (stitching) at each projecting intersection, the lath and the first dynamic bone and the second dynamic bone are removed except for the projecting intersection. The lathe with a force bone can be stretched on the base while both are floating from the base. Even when the first force bone and / or the second force bone is fixed to the base by staples in the vicinity of each projecting intersection, it is possible to avoid the first force bone or the second force bone from being largely bent. The lath with force bones can be stretched on the base in a state in which both the lath and the first force bone and the second force bone are floating from the base except for the projecting intersection.

As the first strength frame and the second strength frame, a steel wire rod having higher rigidity and strength than the wire rod forming the lath can be used, and the shape thereof is generally linear. is there. The first force bone and the second force bone are preferably orthogonal to each other, but are not necessarily limited to orthogonal.
The first force bone and the second force bone are attached to the lath in parallel to the plane formed by the lath, and the direction crossing the direction of the linear material forming the lath (which linear shape It is preferable that the direction intersects with the direction of the material at a large angle.

Examples of lath include metal lath, wire lath, expanded metal, welded wire mesh, diamond wire mesh,
A crimp wire net, an upper wire net, a flat lath, a corrugated lath and the like can be used.

It is preferable that each of the first force bone and the second force bone that forms the protruding intersection portion is protruded from one surface of the lath in a substantially U-shape. In this case, of the first force bone and the second force bone that are parallel to the surface formed by the lath, the portions that form the projecting intersecting portion are such that the bases at both ends are substantially upright from one surface of the lath. Each of the protrusions protrudes to form a rising portion, and the compatible upper portions are bent inward at right angles to each other at a substantially constant height position to form a horizontal portion parallel to one surface of the lath. Therefore, when each projecting intersection is brought into contact with the base and the braced lath is stretched over the base, almost the entire length of at least one horizontal portion abuts the surface of the base, and the compatible upper part is Since it is almost perpendicular to both the surface and the surface formed by the lath, the base portion is curved or inclined with respect to the surface of the base or the surface formed by the lath. When the mortar is applied from the top of the braced frame stretched over the mortar, the mortar tends to spread sufficiently and fully around the upper part and the horizontal part (excluding the base contact part).

In the lath with a force bone of the present invention, the first force bone and the second force bone are located on one side and the other side of the lath to sandwich the lath. The second force bone may be joined (preferably welded) at all or a part of the intersection of the two.

In this case, for example, either one of the first force bone and the second force bone is horizontally arranged in a predetermined manner, a lath is arranged in parallel therewith, and the other force bone is placed on the lath. Are arranged in a predetermined manner, all or a part of the intersection of the first force bone and the second force bone is welded, and further, all or a part of the intersection portion is pressed to form the first force bone and the second force bone. Both of the braces may be formed at a projecting intersection projecting from one surface of the lath at a substantially constant height.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings.

All the drawings relate to a lath with a force bone as an example of an embodiment of the present invention. FIG. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is a right side view, and FIG. 1 is an enlarged cross-sectional view of a main portion of a brim of a protruding intersection in a portion A of FIG. 1 in a plan view, and FIG. Is.

This lath with a skeletal structure is manufactured as follows. First, the first force bone 10 in the lateral direction in FIG.
Are placed in parallel at equal intervals, and the flat lath 12 of the diamond-shaped mesh 12a is placed on the first force bone 10 in parallel to the first force bone 10. On the flat lath 12, the second force bones 14 in the longitudinal direction in FIG. 1 are placed in parallel at equal intervals, and the first force bones 10 and the second force bones 14 are welded at all the intersections. Then, all the intersections of the first dynamic bone 10 and the second dynamic bone 14 are pressed to form the first dynamic bone 10 and the second dynamic bone 1.
4 of the flat lath 12 are formed at a projecting intersection 16 which projects from the back surface of the flat lath 12 at a substantially constant height. The first strength frame 10 and the second strength frame 14 are made of steel wire rod having higher rigidity and strength than the wire rod forming the flat lath 12.

The portions of the first force frame 10 and the second force frame 14 which form the projecting intersections 16 are made to project from the back surface of the flat lath 12 in a substantially U shape. That is, the portions of the first force bone 10 and the second force bone 14 that form the projecting intersecting portion 16 have the base portions at both ends protruding in a substantially upright shape to form the rising portions 10a and 10a and the rising portions 14a and 14a, respectively. The rising portions 10a and 10a and the rising portions 14a and 14
Each of a has a horizontal portion 10b and a horizontal portion 14b that are bent inward at right angles to each other at substantially constant height positions and are parallel to the back surface of the flat lath 12.

The horizontal portion 10b of the first force bone 10 at each projecting intersection 16 is brought into contact with a base (not shown) to be coated with mortar, and the first force bone 10 and / or the second force bone 10 at each projecting intersection 16 is contacted. By fixing the force bones 14 to the base with staples (not shown), the flat lath 12 and all the first force bones 10 and the second force bones 14 except the projecting intersecting portions 16 are applied to the base under force. A lath with bones can be stretched on the base. Therefore, when mortar is applied to the underlayer and the lath with strength bone is embedded in the mortar, the flat lath 12 excluding the projecting intersection 16 and the first strength bone 10 and the first strength bone 10 Since the two force bones 14 can be located, the entire mortar is effectively reinforced by the flat lath 12 and each of the first force bone 10 and the second force bone 14. Therefore, the occurrence of cracks in the mortar can be very effectively prevented.

The first dynamic bone 10 and the second dynamic bone 14 are arranged in parallel with the short and long diagonals of the rhombic mesh 12a of the flat lath 12, respectively, and therefore, in which direction the rhombic mesh 12a of the flat lath 12 is formed. The linear material also intersects the linear material at a large angle, which enhances the effect of reinforcing the mortar and preventing cracks.

The portions of the first force bone 10 and the second force bone 14 which form the projecting intersecting portions 16 project from the back surface of the flat lath 12 in a substantially U-shape, so that each projecting intersecting portion 16 is formed on the base. When the lath with a force bone is stretched over the base by contacting the bases, almost the entire length of the horizontal portion 10b of the first force bone 10 abuts on the surface of the base, and the rising portions 10a and 10a and the rising portion 1 are provided.
4a and 14a are substantially vertical to both the base surface and the back surface of the flat lath 12. Therefore, when the mortar is applied from above the lathe with tension bones stretched on the base, the mortar surrounds the rising portions 10a, 10a and the rising portions 14a, 14a and the horizontal portion 10b of the first strength bone 10 (the foundation portion (Excluding the contact portion) and around the horizontal portion 14b of the second force bone 14 easily and fully.

In addition, the description including the examples and the numerical ranges described for the present invention in the section of the means for solving the problems applies to the above description of the embodiments in principle.

[0023]

According to the lath with a force bone of the present invention, when each protruding crossing portion is brought into contact with a base to which mortar is applied and stretched on the base, all of the lath and the first force bone and the second force bone are obtained. However, except for the projecting intersection, it is held in a state of floating from the base. When mortar is applied on the base in that state and the lath with strength bones is embedded in the mortar, the lath excluding the protruding intersection and the first strength bone and the second strength bone are positioned at the middle position of the thickness of the mortar applied. Thus, the entire mortar can be effectively reinforced, and the occurrence of cracks can be prevented very effectively.
