Abstract

PROBLEM TO BE SOLVED: To provide a three way frame and an assembling method thereof capable of simply and quickly correcting its mounting posture by a proper posture in the case there is an inclination in the mouning posture of the three way frame when construction is executed. SOLUTION: A three way frame 1 built up a column material formed in a U-shape is mounted to the frontage 3 for a gateway of a building by making the frontage downward. Expansible adjusting fixtures 4 are arranged to at least one side of both ends of the upper end face and lower end face of the three way frame 1, and the posture of the three way frame 1 is adjusted by adjusting the length of each of the adjusting fixtures 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an assembling method for assembling a gate-shaped three-way frame for holding a door on an inner surface of a doorway for entrance and exit made of concrete or the like when constructing an apartment house or the like. It is about the three-way frame.

[0002]

2. Description of the Related Art Conventionally, when constructing an apartment house such as an apartment building, as shown in FIG. Is held. This three-way frame 5
Is formed in a U-shape in which the opening is directed downward by the left and right and upper column members 5a, 5a, 5b, and is slightly smaller than the inner surface dimension of the frontage.
The gap between the inside of the frontage and the inside of the frontage is hidden by a decorative surface plate.

[0003]

However, in the above conventional means, if there is an error in the inner surface finishing dimension of the frontage 3 or the dimension of the three-sided frame 5, the posture of the three-sided frame when the three-sided frame is assembled is changed. It may not be correctly assembled due to tilting or distortion. In such a case, conventionally, the position of the three-sided frame is corrected by driving a gap such as a wedge into an appropriate position between the three-sided frame and the inner surface of the frontage, but the operation is very troublesome and takes time. There is a limit to the range of correction.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a three-sided frame which can be easily and promptly corrected to an appropriate position when such a three-sided frame is inclined to be mounted, and a method of assembling the three-sided frame. It is assumed that.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the method of assembling the three-sided frame according to the present invention, the pillar 1a,
A three-sided frame 1 in which 1a and 1b are assembled in a U-shape has an opening 2
When mounting on the entrance 3 of the building with the wall facing downward, the extendable adjustment fittings 4 are arranged on at least one of the upper end face and the lower end face of the three-way frame 1 to adjust the length of the adjustment fittings. Thus, the posture of the three-sided frame 4 is appropriately adjusted.

Further, in the present invention, the left and right column members 1a, 1a
And the upper pillar 1b are connected in a gate shape to provide a U-shaped three-sided frame 1 with the opening 2 facing downward.
The present invention provides a three-way frame having adjustable fittings 4...

Adjustment bracket 4 attached to the three-sided frame 1
Is preferably attached to both the upper end surface and the lower end surface of the three-way frame 1, but may be either one of them. Also pillar material
It may be attached to the intermediate outer surface of 1a, 1a.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. 1 to 4, reference numeral 1 denotes a three-sided frame according to the present invention, in which an opening 2 is turned downward by connecting left and right wooden pillars 1a, 1a and an upper pillar 1b in a gate shape. The composition is in the shape of a letter. Adjustable fittings 4 that can be adjusted to expand and contract are attached to both ends of the upper end surface and both end portions of the lower end surface of the three-way frame 1.

In the embodiment shown in FIG. 2, for example, the adjusting metal fitting 4 is a cylindrical nick nut 6 embedded in the three-way frame 1.
And a bolt member 7 which is screwed into the screw hole 6a of the dovetail nut 6. A flat receiving plate 9 is provided at the tip of the bolt member 7 via a rotating portion 8. The rotating portion 8 is preferably formed with a hexagonal outer peripheral surface with which a tool such as a spanner is engaged, but may be formed with a knurled circular shape. Further, it is preferable to provide an engaging projection 9a for preventing rotation on the upper surface of the receiving plate 9.

According to the present invention, when building a condominium such as an apartment, as shown in FIG. 3, the above-described three-way frame 1 is formed on the inner surface of the doorway 3 constructed of concrete or the like. The three-sided frame 1 is fixed to the inside of the frontage by extending and contracting the upper and lower adjustment fittings 4. At this time, if the three-way frame 1 and the frontage 3
In the case where the three-sided frame is inclined due to the relative dimensional error as shown in FIG. 4, it is possible to easily correct the posture as shown in FIG. 4 by adjusting the respective adjustment brackets 4. it can.

Adjusting bracket 4 attached to the three-sided frame 1
Is preferably attached to both the upper end face and the lower end face of the three-sided frame 1, but may be provided only on one of them, for example, only on the lower end face as shown in FIG. Further, as shown in FIG. 6, the column members 1a may be attached to the intermediate outer surfaces of the column members 1a. In this case, it is effective to correct the outwardly curved warpage of the pillars 1a, 1a.

The adjusting bracket 4 may be of any structure as long as it is in the gap between the three-way frame 1 and the frontage and can extend and contract its length. For example, as shown in FIG. 7, it is also possible to configure a turnbuckle system using upper and lower bolt members 10, 10 having different screw directions and a rotating member 11 for screwing the same. In this case, it is preferable that the receiving plate 12 of the lower bolt member 10 is screwed to the three-way frame 1 as shown in FIG. 7, but the upper and lower receiving plates 12, 12 are the same as shown in FIG. Thus, it may be formed in a flat plate shape so that it can be attached and detached between the three-way frame 1 and the inner surface of the frontage 3. As a result, the necessary number of adjustment fittings 1 can be arranged at a desired position.

As shown in FIG. 9, for example, as a detachable adjustment fitting, a cylindrical member 13 having a screw hole is projected from a receiving plate 14, and a bolt member 15 is screwed into a screw hole of the cylindrical member. Alternatively, a receiving plate 17 may be provided at the end of the bolt member 15 via a rotating portion 16 with which a spanner or the like is engaged.

Although one embodiment of the present invention has been described above, the present invention is not necessarily limited to only the structure of the embodiment, but has the constituent elements and achieves the object of the present invention. Needless to say, the present invention can be appropriately modified and implemented within a range in which the effects can be obtained.

[0015]

As described above in detail, according to the present invention, the length of the adjusting bracket is adjusted even when the three-way frame is mounted in an inclined position due to a relative dimensional error between the three-way frame and the frontage. Thus, the posture can be easily and appropriately corrected, and thereby, a large number of three-sided frames can be correctly assembled in the interior construction work of an apartment house or the like in a short time. In addition, since the three-way frame is firmly fixed to the inner surface of the frontage by the extension of the adjustment fitting, there is a remarkable effect that the work of attaching the three-way frame becomes easy.
