Description

[Detailed Description of the Invention] The present invention relates to a corner bead that can absorb impact force and maintain rigidity.

Conventionally, corner beads were attached to columns and walls to protect their corners, but the corner beads were attached to anchors before joining the finished mortar wall to the surface of the concrete base of the column or wall. was embedded in the concrete base of the column or wall, and after fixing the corner bead body to the anchor, mortar was poured to join the finished wall to the concrete base of the column or wall.

By the way, when embedding this anchor, it is necessary to temporarily fix the anchor by welding it to the reinforcing bars buried in the concrete base, and therefore the concrete must be lifted to expose the reinforcing bars from the concrete base. However, the welding work was troublesome and the workability was poor.

In addition, since the corner bead body is directly covered with the corner of a pillar or wall, the corner bead body cannot absorb the impact force when people or objects collide with it, which may result in unexpected personal injury or property damage. The bead itself was also severely damaged.

Therefore, this idea consists of a horizontal board fixed to the corner of the concrete base of a column or wall using fixing devices such as screws, and both ends of the horizontal board protruding upward in a direction approximately perpendicular to the horizontal board. two side parts formed, a groove formed between the two side parts, a flat main body part formed by bending the upper ends of the two side parts outward in a substantially horizontal direction, and the flat main body part. A corner bead comprising an elastic corner bead main body having a hat-shaped cross section and a wing part having a cushion part attached to the lower surface thereof, and a joint part closing the groove formed in the corner bead main body. By providing this, it is an object of the present invention to obtain a corner bead that can be easily attached to a corner portion of a pillar or the like, improves workability, absorbs impact force, and has rigidity.

An embodiment of the present invention will be explained below with reference to the drawings. In FIG. 1, reference numeral 1 denotes the base of a column made of reinforced concrete with reinforcing bars 2 buried therein, and a finishing wall 3 made of mortar is joined to the surface of the column 1 except for the corner portion 4 of the concrete base 1. As a result, a space 5 is formed on the surface of the corner 4, which is surrounded by the corner 4 and the end surfaces 3a and 3b of the wall.

A corner bead main body A made of synthetic resin and having an elastic hat-shaped cross section is attached in this space 5. The specific structure of this corner bead main body A will be explained. This corner bead main body has a horizontal base plate 6 fixed to the corner part 4 of the concrete base 1 with fixing devices such as screws, and has both ends of the horizontal base plate 6 vertically upwardly protruding from each other. When two side parts 7a and 7b are formed,
An elongated groove 8 is inevitably formed between the side plates 7a and 7b. Further, both side plates 7a,
The upper end of 7b is bent outward in a substantially horizontal direction to form flat main body parts 9a, 9b, and the tips of these flat main body parts 9a, 9b are bent to form wing parts 10a, 10b.
Cushion portions 11a and 11b are attached to the lower surface thereof to press against the wall surface of the finished wall 3.

The joint material B, which is fitted into the groove 8 of the corner bead main body A and plays the role of closing the groove 8 and hiding fasteners such as screws, is made of rubber or soft synthetic resin and maintains harmony with the color tone of the colored interior. The pillars can also be made to stand tall or coated with fluorescent paint to help identify them even in the dark.

To attach the corner bead main body A having the above structure to the corner 4 of a column, first align the horizontal substrate 6 of the corner bead main body A to the corner 4 of the concrete base 1, and then attach the horizontal substrate 6 to the corner 4 of the concrete base 1. Screw 1
2 to the corner portion 4. Next, the joint material B is fitted into the groove 8 formed in the corner bead main body A to complete the installation.

FIG. 2 shows another embodiment of the present invention, in which a rising piece is formed integrally with the corner bead main body, and this rising piece is used to form a space in which the corner bead main body is accommodated. The corner bead main body and the member for forming the space are used together, thereby eliminating the waste of separately preparing each, and providing a beautiful wall finish.

Its structure includes a joint piece C1 which is integrally joined to the flat plate-like substrate 6 of the corner bead main body A and is also joined to the corner part ₄ of the concrete base 1, and a piece rising from both ends in a shape that spreads toward the end. In addition to coupling C ₂ , the wing part 10 of the corner bead body
Cushion part 11 attached to a, 10b
A, 11b are brought into contact with the rising piece _C2 , thereby eliminating the gap between them and the wall surface of the finished wall 3. In order to join the corner bead main body A, in which the rising piece C ₂ and the joining piece C ₁ are integrally attached, to the corner part 4 of the concrete base 1, the joining piece C ₁ is
is fixed to the corner portion 4 together with the flat substrate 6 of the corner bead main body A using screws 12, and then mortar is poured into the gap formed between the rising piece _C2 and the surface 1a of the concrete base for finishing. This is what forms the wall 3, and the corner bead body A
is attached to the corner portion 4, and a space 5 is formed in which the corner bead main body A is housed. That is, since the corner bead main body A is provided with the rising piece _C2 for forming the space 5, the corner bead main body A and the member for forming the space 5 can be used together, eliminating the waste of preparing each separately. Moreover, since the wall can be finished using this rising piece _C2 as a reference, the wall can be finished easily and beautifully.

This corner bead body A and rising piece C ₂
There is no problem even if it is a separate body.

As described above, according to the present invention, since the main part of the corner bead body that comes into contact with people or objects is made into a flat plate shape, bending stress is concentrated due to impact. The side plates can absorb a moderate amount of impact force applied to the flat main body and maintain rigidity, preventing damage to the corner bead body and preventing the corner bead body from colliding with the body even if a person collides with it. The percentage of accidents is small, and property damage is also avoided.

In addition, since the concave groove can be closed in the joint material, fixing tools such as screws are hidden and the appearance is not spoiled, and since the joint material can be colored, it is possible to maintain harmony with the color tone of the room, and the joint material can be colored with fireflies. If you apply luminous paint, you can identify the existence of pillars etc. even in the dark.

Furthermore, since the corner bead main body is directly fixed to the corner of a pillar or the like using a fixing device such as a screw, it has advantages such as being strong and easy to install.
