BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame-to-frame connection structure, and more particularly to a frame-like connection structure comprising a vertical frame and a horizontal frame for mounting a window or a door.

[0002]

2. Description of the Related Art Conventionally, a frame for mounting a window or a door of a building is constructed by welding a material such as steel or stainless steel at a construction site to a predetermined size and assembling it on a skeleton side or at a factory. 2. Description of the Related Art A vertical frame, a horizontal frame, and a connector for a frame are created as a set and assembled at a building site.

[0003]

The method of assembling by welding on site has the disadvantage that the material is denatured by heat, the material itself discolors and the appearance is impaired.
In particular, in recent years, materials obtained by laminating a decorative material such as PVC sheet on a steel plate have been frequently used, and joining by welding has become inconvenient from the viewpoint of protecting the laminate sheet. I have.

The method of manufacturing a frame and a connector at a factory and assembling the frame at the site does not apply heat to the material, but the above-mentioned drawbacks have been solved. However, the assembling strength and stability, reliability, Alternatively, satisfactory results have not always been obtained from the viewpoint of workability. As an example,
As shown in FIG. 5, hollow paths 5, 5 are formed in the metal frames 2, 4 along the longitudinal direction thereof, and connecting pieces A are provided in both hollow paths.
After screwing a screw screwed into the connecting piece A, the frame is connected by pressing one side of the connecting piece A against the inner wall 6 of the frame. 49-45381). This is an effective one that can assemble a rectangular frame simply by performing a simple operation of screwing screws at the construction site, but the engagement between the frame body and the connection piece is one side of the connection piece and the frame body Although it is performed only by frictional engagement of one inner wall surface, it can be effectively used as a connecting means of a lightweight frame such as an aluminum sash, but a steel frame for door attachment. However, as a joining means for a large and heavy building as described above, it is difficult to apply the joining means because the holding strength of the joint is not sufficient.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned disadvantages of the conventional frame connecting means, and to provide a frame connecting structure which has sufficient joining force and strength while facilitating assembly work on site. The purpose is to get.

[0006]

In order to solve the above-mentioned problems and achieve the object, the present invention provides a frame having a hollow portion,
From a connecting member inserted into both hollow portions of two adjacent frame members, a fixing member inserted between the frame member and the connecting member, and an expanding member for expanding a gap between the connecting member and the fixing member. A frame connecting structure in which the gap between the connecting member and the fixing member is enlarged by the action of the expanding member, whereby the two frictionally engage with the frame, thereby connecting the adjacent frames. Is disclosed.

It is preferable to form the frame, the connecting member, and the fixing member by processing a steel plate, but it is not necessarily limited thereto, and a light alloy such as stainless steel or a resin such as hard synthetic resin may be used. Materials can also be used. Connecting member,
The fixing member may be a plate-shaped member, but a member formed by appropriately processing a so-called U-shaped steel in which a side portion along a long piece is bent is particularly preferable from the viewpoint of strength.

As the expanding member for enlarging the gap between the connecting member and the fixing member, a screw member screwed to the fixing member can be used, but the screw member may be a thumb screw.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the accompanying drawings. FIG. 1 shows a state in the middle of assembling the frame using the frame connecting structure according to the present invention, and FIG. 2 shows a state after the assembly. The horizontal frame 10 and the vertical frame 20 have substantially the same cross-sectional shape, and the door contact portions 12 and 22 (FIG. 4) are provided substantially at the center of the inner surfaces 11 and 21 when attached to the building frame.
) Are provided in the longitudinal direction. Both sides of the inner surfaces 11 and 21 are bent at right angles to the outer rising portions 13,
23, and further bent inward to form the inner surfaces 11, 2
Outer surfaces 14, 24 parallel to 1 and inner surfaces 11, 2
After being bent toward 1 to form the inner rising portions 15 and 25, the inner surfaces 11 and 21 are further bent inward at positions separated from the inner surfaces 11 and 21 by a fixed distance h <b> 1 and h <b> 2 to support the inner surfaces 11 and 21 in parallel. The plane portions 16 and 26 are configured. FIG.
As shown in (1), the front end portions of the support flat portions 16 and 26 are opposed to each other with a certain interval, and form openings S1 and S2.

That is, the frame shown in this embodiment is
It has a hollow portion on both sides in the longitudinal direction and an opening at the center, and has a pair of supporting flat portions parallel to the inner surface on both sides of the opening. In addition, notches 18 and the like are provided at the ends so that the joints at both ends can be fitted and sealed with each other and joined in a good-looking state when assembled.

FIG. 3 shows the connecting member 30, the fixing member 40, and the expanding member 50 according to the present invention. The connecting member 30 is preferably formed of a steel plate,
1 and rising portions 32 formed at the left and right longitudinal ends, and are bent at a connection angle of a frame to be connected, usually 90 degrees. The height of the rising portion 32 and the lateral width of the flat portion 31 are such that the right and left rising portions 32 can be fitted together with the rising portions of the fixing member 40 described later into the hollow portions formed on the above-mentioned both sides of the frame bodies 10 and 20. Dimensions. The rising portion 32 may have an extending portion 33 as shown in FIG. 3, or may have the same height as the whole. The thickness of the flat portion 31 is such that the flat portion 31 and the fixing member 40 can be fitted into the space h1 between the flat portion 11 and the support flat portion 16 of the frame body while maintaining a predetermined play gap. And

The fixing member 40, like the connecting member 30, is preferably formed of a steel plate, and includes a flat portion 41 and rising portions 42 formed at left and right longitudinal ends. The height of the rising portion 42 and the width of the flat portion 41 are the same as those of the rising portions 32, 32 of the connecting member 30 described above.
In the state where the frame member 1 is fitted together with the connecting member 30.
The dimensions are such that they can be inserted into the hollow portions formed on both sides of 0 and 20. The rising portion 42 of the fixing member 40
May have the extension 43, and may have the same height as a whole. Further, a screw hole 44 for screwing a later-described expanding member is formed in the flat portion 41. In this embodiment, two pieces are provided.

In this embodiment, the expanding member 50 is shown as a bolt that is screwed into the screw hole 44 formed in the fixing member 40 described above. Next, an operation procedure for joining and fixing the frame using this device will be described. First, one of the vertical frame and the horizontal frame (in the following description, the vertical frame 2
One of the bent sides of the connecting member 30 is inserted into the hollow portion of 0). Next, the fixing member 40 is inserted into the space between the supporting flat portion 26 of the frame and the connecting member 30 with the expanding member 50, that is, the bolt 50 temporarily fixed to the fixing member 40. Since there is an opening S2 between the parallel supporting flat portions 26, the bolt can pass through the opening and the fixing member 40 can enter the hollow portion of the frame. After the connecting member and the fixing member are positioned at a predetermined position with their ends substantially coincident with each other, the bolt 50 is rotated to allow the bolt to enter inward. Since the tip of the bolt comes into contact with the flat portion of the connecting member, the connecting member 30 and the fixing member 40 separate in directions opposite to each other as the bolt enters (see FIG. 4). Frame 2
0, the connecting member 30 and the fixing member 40 can be moved to some extent, but the bolts are screwed in such a state that they cannot be separated from each other. Then, the hollow portion of the horizontal frame 10 is inserted and pushed in until the ends of both frames reach the desired positions.

In this embodiment, the notch 1 formed in the above-mentioned horizontal frame is raised by slightly raising the horizontal frame 10 and then further pushing it in, and then further pushing it down.
As shown in FIG. 2, a part of the vertical frame enters the inside of the frame 8, and a good-looking joint in which the joints are completely fitted can be obtained. In this state, the fixing member 40 is fitted into the horizontal frame in the same manner as in the case of the vertical frame, and the bolt is screwed into a temporary fixing state.
By repeating this method also at the joint portion of another frame, a rectangular frame having three or four sides is formed. Finally, by further screwing the bolts at the joints, for example, in the vertical frame 20, the connecting member 30 abuts on the inner surface 21 side of the vertical frame, the fixing member 40 abuts on the support plane portion 26, and the two members are mutually connected. The frictional force between them secures them integrally and securely.

Although the frame has been described as having the door abutment 12 on its inner surface, the inner surface may be a simple plane depending on the place where the frame is used. Also, the cross-sectional shape of the frame is not limited to this shape, as long as the connecting member and the fixing member can be integrally fitted with a certain play and have an opening through which the expanding member can pass. All goals are achieved. Further, such a cross-sectional shape does not need to be the same shape over the entire length of the frame body, and it is sufficient if the cross-sectional shape is at least at the joining end where the connecting member is inserted. Further, fine irregularities may be provided on each or one of the surfaces where the frame body and the connecting member or the fixing member frictionally engage with each other to enhance the fixing force.

[0016]

[Effect of the Invention] Since the present invention has the above-described structure, it can be assembled at a factory and brought to a construction site by simple work. With the simple operation of expanding the gap between the frame member and the fixing member, the connecting member and the fixing member are friction-joined to the inner surface at two locations of the frame body to be joined, so that reliable joining strength can be obtained. In addition, the connecting member is a solid U-shaped steel having no screw holes and the like, and can provide sufficient mechanical strength to the joint portion of the frame, and is used as a joining member of the frame supporting a heavy object such as a door. Especially effective.
