Abstract

PROBLEM TO BE SOLVED: To provide a frame structure and a member for connecting ends of a frame capable of manufacturing the frame easily and inexpensively and saving labor in construction work. SOLUTION: A member for connecting ends of frame 9 is screw-fitted on a longitudinal end face 6 of a rigid frame 5a by a countersunk head screw 7. A body 1 is provided with a fitting 2, and an upper frame 4a is provided on it. The vertical frame 5a is inserted between the upper frame 4a and the body 1. At this time, since a wedge-shaped elastic piece 11 of the member for connecting ends of frame 9 is bent to have an elastic force and the longitudinal end face 6 of the vertical frame 5a is pressed on an orthogonal end face 12 of the upper frame 4a by this elastic force without causing a clearance, the work for removing warp of the frame becomes unnecessary, and this member for connecting ends of frame can be manufactured easily and inexpensively. Moreover, a screw becomes unnecessary to fix the orthogonal end face 12 and the longitudinal end face 6 of each frame 4a, 5a at the time of construction at site, thereby saving labor in the construction work.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure in which a longitudinal end face and an orthogonal end face of each frame attached to a fitting frame such as a sash, a door, etc. are fixed to the frame, and a frame end connecting member.

[0002]

2. Description of the Related Art As a conventional metal frame structure, there has been known a metal frame structure in which longitudinal end faces in the longitudinal direction of left and right vertical frames are fixed to the end faces perpendicular to the longitudinal ends of upper and lower frames. For example, as shown in FIG. 6, the upper frame 4a and the vertical frame 5a are formed by bending a metal plate into a substantially L-shape. An L-shaped connection metal fitting 22 is welded or bonded to the longitudinal end of the upper frame 4a so as to be flush with the orthogonal end surface 12 of the upper frame 4a.
With the longitudinal end face 6 of the vertical frame 5a in contact with the orthogonal end face 12 of the upper frame 4a, the vertical frame 5a is connected to the L-shaped connecting bracket 22.
Are connected by screws 23.

[0003]

The above-mentioned conventional picture frame is:
Since the metal plate is manufactured by bending, there is a warp as shown by a two-dot chain line in FIG. Due to this warp, when the frames are connected to each other with a screw, the end joints do not adhere to each other and a gap is formed, which has a problem in the function of the frame as a decorative article. In order to prevent the gap at the time of fixing the torso, it is necessary to remove the warp from the frame at the time of manufacturing the frame, resulting in an increase in cost. In addition, welding or bonding is required to provide an L-shaped connection metal fitting for connecting each frame with a screw on the frame, so that there is a problem that the manufacturing of the frame is troublesome and expensive. Furthermore, although the frame structure is assembled on-site, the operator must tighten the screws so that the joints of each frame are securely contacted with no gap at the time of this construction, which makes the installation difficult. There is. Also, when assembling the frame at the opening of the frame (wall) at the site, it is difficult to tighten the screw if this screw is located directly opposite the opening of the frame when screwing the end face of each frame to the end face However, there is a problem that the work cannot be easily performed. An object of the present invention is to make the frame easy and inexpensive, to save labor for the construction work, and to prevent a gap from being formed between the end faces when the end faces of the frame are fixed by piercing.

[0004]

In order to solve the above-mentioned problems, according to the present invention, there is provided a frame structure in which an orthogonal end surface of a first frame and a longitudinal end surface of a second frame are longitudinally connected.
The second frame is urged against the orthogonal end surface of the first frame in the first frame direction to bring the end surface into a crimped state (claim 1).

[0005] In the frame structure according to the first aspect,
A frame end connecting member for connecting the respective end faces of the first frame and the second frame to the end of the frame is provided with a mounting piece mounted on the back surface of the second frame and a compression piece interposed between the mounting piece and the frame. An elastic piece is provided which presses the longitudinal end face of the second picture frame to the orthogonal end face of the first picture frame without any gap by an elastic force (claim 2).

More specifically, the elastic piece is formed in a wedge shape that tapers toward the fitting. Further, the elastic piece is provided with a filler hole (claim 4). Preferably, the width of the arm in the direction in which the fitting is projected on the outer periphery of the hole for the filler of the elastic piece is reduced in the direction in which the fitting is projected toward the fitting (claim 5).

Further, the mounting piece is formed so as to be able to be clamped by a clamping portion provided at a longitudinal end of the second frame.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 3 based on one corner where the ends of an upper frame and a vertical frame (right) are butt-connected. The same is true for the upper frame and the left vertical frame, and the lower frame and the left and right vertical frames at the ends. A fitting 2 is attached to an opening 1 a of a frame (wall) 1, and a frame 3 is provided on the indoor side of the fitting 2. Picture frame 3
Is composed of upper and lower frames 4a and 4b as first frames and left and right vertical frames 5a and 5b as second frames. Each of the frames 4a, 4b, 5a, 5b is formed by bending a metal plate material into a substantially L-shaped cross section as shown in FIGS. A flat head screw 7 is provided on the longitudinal end face 6 of the vertical frame 5a in the longitudinal direction.
A screw accommodation hole 8 capable of accommodating the head is formed. A frame end connecting member 9 is screwed to a longitudinal end surface (upper end surface) 6 of the vertical frame 5a on the side opposite to the frame 1 by a countersunk screw 7 inserted into a screw receiving hole 8.

As shown in FIGS. 1 and 2, the frame end connecting member 9 includes a mounting piece 10 mounted on the back surface of the longitudinal end face 6,
The elastic piece 11 extends obliquely downward continuously from the mounting piece 10 and is integrally formed with the elastic piece 11 having a wedge shape. Elastic piece 1
1 is a vertical frame 5a for connecting the frame edge connecting member 9 as described later.
When the vertical frame 5a is assembled between the frame 1 and the end face of the upper frame 4a, the vertical frame 5a is interposed in a compressed state between the vertical frame 5a and the frame 1.
Has an elastic force capable of pressing the longitudinal end surface 6 of the vertical frame 5a without any gap. In addition, the frame 3 is attached to the elastic piece 11 by the frame 1.
Filler holes 13 are provided to prevent the flow of the filler to be filled between the frame 3 and the frame 1 when attached to the frame 2 and the fitting 2. The arms 14a, 14b, and 14c, which form the filler holes 13 and are arranged in parallel in the direction in which the fittings are projected, become wider in the viewing direction in order as the distance from the fitting 2 increases, and as shown in FIG. With the middle part of the frame pressed against the edge 1c of the frame 1,
The elastic force of the elastic piece 11 acting on the end of the frame 3 is made substantially constant irrespective of the pressure contact position between the edge 1c and the inclined side 15 when the a and 4a are fixed at the end of the body.

The attachment of the frame 3 to the frame 1 and the fitting 2 is as follows.
After the fitting 2 is attached to the skeleton 1, the upper frame 16 of the fitting 2
An upper frame 4a is screwed and fixed to an L piece 17 attached to a longitudinal middle portion of the frame, and a frame end connecting member 9 is attached between the upper frame 4a and the frame 1 toward the fitting 2. Push 5a. Then, the elastic piece 11 is bent and compressed between the vertical frame 5a and the frame 1 as shown in FIG.
Generates an elastic force for pressing the longitudinal end face 6 of the upper frame 4a to the orthogonal end face 12 of the upper frame 4a. The elastic force urges the longitudinal end face 6 toward the orthogonal end face 12 to fix the upper frame 4a and the vertical frame 5a to the trunk. You. In this state, the vertical frame 5a is screwed into the L piece 17 provided at the longitudinal middle portion of the vertical frame 18 of the fitting 2 from the inside with a flathead screw, and is welded and fixed to an anchor (not shown) provided on the frame 1 as is well known. You. The attachment position of the L piece 17 to the fitting frame is such that when the L piece 17 and each frame are screwed together, the tightness of the elastic piece 11 prevents the close contact between the longitudinal end face 6 and the straight end face 12 due to the elastic force of the elastic piece 11. Can be installed where it cannot be. Then, the decorative board 19 is provided on the skeleton 1 side, and the construction work is completed. At this time, a filler (mortar) may be filled between the frame 1 and the frame 3, but the flow of the filler between the frame 1 and the frame 3 may be prevented by the filler hole 13 provided in the elastic piece 11. Instead, the periphery of the frame end connecting member 9 is also filled with the filler.

When the frame 3 is assembled, the elastic piece 11
Has a wedge shape, so that it can be easily pushed in, and the orthogonal end face 12 and the longitudinal end face 6 are crimped by the elastic force of the frame end connecting member 9, so that screwing is not required, and the construction work becomes easy. . Since the elastic piece 11 has a wedge shape, the frame edge connection member 9 is common to frames having different expected dimensions.
The end faces 6, 12 of the picture frames 4a, 5b are connected by the elastic force of the elastic pieces 11 being compressed, so that even if the relief dimension L between the frame 1 and the fitting 2 is different, Can be used. Further, since the screw is not fixed, even if the screw faces the opening surface 1b of the frame 1 and it is difficult to tighten the screw as in the related art,
The torso can be fixed easily. Further, the frame end connecting member 9 is long in the direction in which the fitting 2 is viewed, and the longitudinal end surface 6 of the vertical frame 5 is fixed in the direction of the torso when the mounting surface 10a is long in the direction in which the mounting piece 10 is viewed.
Therefore, even if each frame is warped, the longitudinal end face 6 and the orthogonal end face 12 of each frame can be pressed without gap.

FIG. 5 shows another embodiment.
A part of an end portion of the longitudinal end face 6 of the vertical frame 5 is formed in a holding piece 20, and a mounting piece 1 is provided between the back surface of the longitudinal end face 6 and the holding piece 20.
0 to form a holding portion 21 capable of holding the holding portion 21.
The mounting piece 20 is sandwiched between them. In this embodiment, no screw is required for mounting the frame end portion connecting member 9, and the connection between the vertical frame 5 and the frame end portion connecting member 9 is simplified.

[0013]

As described above, according to the present invention, when the orthogonal end face of the first picture frame and the longitudinal end face of the second picture frame are torso-fixed, a picture frame end connecting member is provided on the longitudinal end face of the second picture frame.
The frame end connecting member is interposed between the second frame and the frame in a compressed state, and the orthogonal end face and the longitudinal end face are brought into close contact with each other by the elastic force of the frame end connecting member. The work of assembling the picture frame is easier than in the case of
On-site construction time is reduced. In addition, the frame end connecting member has a length in the direction in which the fittings are projected, and the longitudinal end face is pressed by a long surface in the projected direction of the mounting piece, so that the orthogonal end face and the longitudinal end face are closely adhered to each other irrespective of the warpage of the frame. In addition, it is possible to prevent a decrease in the performance of the frame. In addition, this eliminates the need to remove the warpage of the frame and to provide an L-shaped connecting bracket when manufacturing the frame, which simplifies the manufacturing of the frame and reduces the cost.
