Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cellular concrete,
The present invention relates to an anchor for cellular concrete fixed to a wall, a floor, a ceiling, or the like.

[0002]

2. Description of the Related Art Conventionally, an anchor for cellular concrete is tightened with screws or bolts as shown in FIG.
As shown in FIG. 11, a type in which the cylindrical expansion body 5 is expanded,
It has a cylindrical derivative 6, and is broadly divided into one that expands and fixes the lower expansion body 7.

[0003]

However, since cellular concrete is brittle, when the bolts and the like are tightened and the expanded body is expanded, the expanded body itself sinks into the cellular concrete, and furthermore, the area around the expanded body expands. Not only was it small and rattled, it was not possible to maintain the strength as an anchor, but there was also a danger that the mounting hardware would come off.

Therefore, the present invention solves the above-mentioned conventional problems and is easy to attach to cellular concrete.
It is another object of the present invention to provide a rattle-free anchor capable of firmly fixing a mounting hardware.

[0005]

According to the present invention, in order to achieve the above object, a notch 11 is provided at a rear portion of an anchor body 10 as shown in FIGS. 1 and 2, and a hole 12 for a set pin is provided. are doing.

The opening and closing body 13 which can be opened by the springs 18a and 18b shown in FIG.

A and 18b are fixed so that they can be opened and closed.

The opening and closing members 13a and 13b are shown in FIGS.
Attachment portions 14a and 14b are formed so as to be set in the semicircular groove portion 11 of the anchor main body so as to be settable in the semicircular center position, and have set pin holes 15a and 15b. .

As shown in FIG. 3, the opening / closing members 13a and 13b have sharp triangular projections 17a and 17b, which have been filed in Japanese Patent Application No. 11-147071, and 17
a, 17b can be engaged with each other,
a and 16b.

As shown in FIGS. 8 and 9, the tightening nut is integrated with the washer 31, the nut 32, and the file-like projection 30 which have already been submitted in Japanese Patent Application No. 11-147071, and embedded. It is formed as a fitting nut 33.

FIG. 5 is a front view of the opening / closing body portion. As shown in FIG. 4, the opening / closing bodies 13a and 13b
In order to increase the resistance of the pulling force, a semicircular shape is formed, and springs 18a, 18a are provided inside the mounting portions 14a, 14b.
b is provided, and is fixed to the groove 11 of the anchor main body 10 by the set pin 19.

[0011]

As shown in FIG. 4, the opening / closing members 13a and 13b are formed in a semicircular shape.
By tightening 1, not only does the opening and closing members 13a, 13b of the cellular concrete 3 cut into the inner surface, not only preventing the lateral runout but also increasing the resistance of the pulling force,

Since the opening / closing members 13a and 13b are formed in a semicircular shape, as shown in FIG. 5, they form a circle at the time of insertion and have little rattling with the mounting through hole.

As shown in FIG. 3, the opening and closing members 13a, 13
b has pointed triangular projections, 17a and 17b, and on the opposite side, 17a and 17b form inverted triangular portions 16a and 16b, which can mesh with each other, so that they can easily bite into the aerated concrete surface. It prevents idle rotation and serves as a lock.

As shown in FIG. 8 and FIG.
-147071 "of the opened and closed bodies 13a, 13b
Since the size can be set to about minus 10 mm depending on the distance L between the inner wall surface of the cellular concrete 3 and the inner wall 1, the strength of the anchor can be increased in proportion to the L size.

The embedding nut 33 is shown in FIGS.
As shown in FIG. 7, the washer portion 31 and the nut portion 32 are integrally formed, and the file-like projection 30 is formed on one side. Therefore, by tightening the nut portion 32, the cellular concrete surface 3 is formed into a file-like shape. The projections 30 themselves can be compassed while shaving, and since the file-shaped projections 30 are on one side, shaving powder is discharged from one side, so that the cellular concrete can be quickly scraped.

Further, the nut 32 is embedded in the same surface as the outer surface of the cellular concrete 3 and the anchor can be locked, so that the anchor can be fixed without rattling and the anchor and the mounting hardware can be stabilized. Sex is increased.

[0017]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

First, the anchor 1 is attached to the cellular concrete surface 3.
At the mounting position of 0, a through hole is provided using a drill or the like,
As shown in FIG. 5, the washer 20 and the nut 21 are temporarily tightened, and the opening / closing bodies 13a and 13b are inserted in a closed state.

As shown in FIG. 6, the opening and closing members 13a, 13b
When they pass through the through holes, they are opened by the springs 18a and 18b.

As shown in FIG. 7, by pulling the anchor body 10 forward, the triangular projections 17a, 17b of the opening / closing bodies 13a, 13b catch the inner surface of the cellular concrete, so that the washer 20 becomes easy to bite. When the nut 21 is fully tightened, the triangular projections 17a, 17b of the semicircular opening / closing bodies 13a, 13b catch the inner surface of the cellular concrete, so that the nut 21 is easily bitten, and the washer 20 and the nut 21 are fully tightened. Accordingly, the semicircular opening / closing bodies 13a and 13b bite into the cellular concrete surface 3.

After the final tightening, the nut 21 and the washer 20
, And as shown in FIG.
And tighten the book with a box wrench.

The integral embedding nut 33 has the file-like projections 30 formed on the back surface of the washer portion 31.
Since the surface of the cellular concrete 3 is formed with the file-like projections 30, the cellular concrete surface 3 is formed by tightening the embedding nut 33.
But you can compass while shaving.

As shown in FIGS. 8 and 9, the outer surface of the cellular concrete 3 and the top of the embedding nut 33 can be placed so as to be flush with each other.

FIG. 9 shows an anchor bolt 10 of the present invention using an integral embedding nut 33 which has been filed in Japanese Patent Application No. 11-147071 and attaching the mounting hardware 23 to the washer 2.
0, a state where the nut 21 is mounted.

[0025]

As described above, according to the present invention, the anchor is made to penetrate the cellular concrete 3 itself, and
Since 3a and 13b are opened, a great strength can be obtained in the inside of the conventional cellular concrete 3 far more than a structure having an expanded body.

The opening and closing member 13 is attached to the fragile cellular concrete 3.
Since the locking force is increased at a and 13b and the opening and closing members 13a and 13b are semicircular, it is possible to provide a stable anchor without rattling with the through-hole.

Further, with the integrated embedding nut 33, there is no backlash when mounting hardware, and the mounting strength can be reliably obtained.

[0028] Since a certain strength can be obtained for mounting, the work efficiency is remarkably improved.

Since the structure is made of metal and the penetration method is used, a great strength can be obtained. When mounting hardware, it can be used as a welding anchor without using the washer 20 and the nut 21.

If the rear part is a hollow surface because the mounting method is through penetration, it can be used for panels, blocks and various foam materials.
