Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame structure, particularly to a frame structure in which two frames of the same shape are joined at an oblique angle of 45°.

Each frame joint has at least one flange.

This joining method involves providing a protrusion on the plate surface welded onto the flange of each frame joint close to the end of the frame joint where the diagonal joint is formed, and a first recess on one side. A pair of clamping plates having a second recess on the other side are positioned.

The sides of the first recess press against the protrusion, and the second recess presses against the surface of the frame joint adjacent to said flange and adjacent to the end of the joint forming the diagonal joint. The structure is such that it can be pressed.

Such an arrangement forces the clamping plate towards the flange, thereby pressing the projections together.

The present invention also provides a frame structure consisting of a pair of identically shaped frames positioned at an oblique angle of 45 degrees.

Each joint has at least one protrusion on the plate surface on the flange of each frame joint adjacent its end.

The clamping plate has two recesses at each of its two opposite ends, one first recess being located on both sides of the protrusion so as to press against the protrusion, and the other second recess having: Press against the surface of the frame joint proximate the flange and proximate the end of the joint forming the diagonal joint.

The clamping plate thus tends to be compressed between the projections and the frame surface, thereby pressing the projections inwardly towards each other.

If a diagonal joint is used to connect two frame joints each with two flanges, two flat clamping plates are required to connect each flange.

The two clamping plates can be effectively combined with a resilient cover member that engages the edges of each frame joint at a diagonal joint.

As a result, the cover members are gripped at each end by the clamping plates such that the entire length of the cover member presses against the frame joints and ensures uniform seating of the longitudinal joints between these frame joints. Strengthen the entire length.

Furthermore, the present invention can be applied to two joints.

That is, each joint has only one flange, and only one flat clamping plate is used with a resilient cover member, which is secured to one end by the clamping plate.

The remainder of this cover piece rests loosely on the edge of the frame joint adjacent to the diagonal joint.

Preferably, the cover member is separated from two flanges joined together by a longitudinally extending convex curve.

In this embodiment, the clamping plate is more securely engaged with the cover member, and the elasticity of the cover member is more effective.

Hereinafter, embodiments of the present invention will be described in detail based on the accompanying drawings.

Reference numerals 1 and 1a designate identical frame joints of door frames that are joined to each other by diagonal joints 2 at an angle of 45°, for example.

The plate 5 is fixed by spot welds 4 to the flange 3 of the joint 1 (see FIG. 1).

The plate 5a is likewise fixed to the flange 3a of the joint 1a by means of spot welds 4.

The plates 5 and 5a lie flat on the flanges 3, 3a, except for their edges 6 and 6a.

Further, its ends are each narrower in width and have shoulders 7,
7' and 7a,? 'a' and are forcibly pushed in, and remain in proper positions on the aforementioned flanges 3, 3a, respectively.

In this way, a cavity is created that allows the joint to be suspended by one or more hooks during manufacture.

At the diagonal joint 2, the adjacent edges of the plates 5 and 5a form teeth 8, 9, respectively, so that when the frame joints 1, 1a are joined diagonally, the teeth 8, 9 mesh precisely.

The spaces shown between the teeth 8, 9 are only shown for clarity on the drawings.

The teeth 8, 9 prevent relative movement of the frame joint 1.1a.

The plates 5 and 5a are each provided with a protrusion 10.10a, and when the joints 1 and 1a are joined together, the protrusion 10.10a is located in a line perpendicular to the diagonal joint 2 and is symmetrical to the joint 2. It is configured to be located at

The tightening plate 11 has legs 13 and 13a, and extends from one side to form a trapezoidal cutout first recess 12, and the opposite side has a right-angled cutout with an apex of 174 circles. A second recess 14 is formed.

The clamping plate 11 has a projection 10, 10a located in the first recess 12 and engaging a respective leg 13.13a;
The curved portion 15 of the cover member 16 received in the second recess 14 is fastened flat onto the plates 5, 5a covering the flanges 3.3a of the joint portions 1 and 1a.

The cover part 16 has a flange 17.17a which engages a corresponding web 18=18a of the frame joint 1, 1a.
are provided on both sides of the curved portion 15.

Cover member 16 extends lengthwise along diagonal joint 2 between webs 18 and 18a.

In FIG. 1, only the second flange 19 of the joint 1 is visible.

The plates 20 and 20a are fixed by spot welds 4 at the second flanges 19.19a of the joints 1 and 1a.

Like the plates 5, 5a, the frames 20 and 20a also have edges 21 and 21a, respectively.

The edges 21, 21a are formed between the shoulders 22, 22' and 22a, 22'a, respectively, and have a narrow width.

The plates 20 and 20a have protrusions 23 and 23a1 and teeth 24 and 25, respectively.

These teeth 24 and 25 correspond to the teeth 8 and 9 of the plates 5 and 5a.
Similarly, they are each made to engage with each other.

The tightening plate 26 corresponding to the tightening plate 11 has a diagonal joint 2.
It is there to fix the second flanges 19, 19a on the top.

This clamping plate 26 includes legs 28 and 28a, and defines a first recess 27 cut out in a trapezoidal shape L1 between which the recess 27 is formed.
A second recess 29 is formed on the opposite side.

The tightening plate 26 has protrusions 23 and 2 located in the first recess 27.
3a is adapted to rest flatly on the frame 20.20a, with the legs 28 and 28a pressing the protrusions 23, 23a inwardly into each other.

The second recess 29 accommodates the curved part 15 of said cover part 16, whose flanges 17 and 17a join the opposing webs 18 and 18a of the joint parts 1 and 1a. .

The clamping plates 11 and 26 are the clamping plates 11.2 of the joints 1 and 1a.
The flanges 3 and 3a1 or 19 and 19 facing the flange 6 are pulled together at a predetermined position, and not only are they diagonally joined at this flange position, but also this tightening plate 11.2
The tension generated at 6 has the effect that the cover member 16 is strongly pressed at each end against the webs 18 and 18a of the joints 1 and 1a.

This effect is further enhanced when the cover member 16 is made of a slightly elastic material, but the tightening plates 11 and 26
Under the influence of the pressure at the respective ends caused by the flanges 17 and 17a of the cover member 16
The material is made of a material that is mechanically hard enough to join the webs 18 and 18a of 1a and 1a.

As a result, the diagonal joint 2 extending between the webs 18 and 18a is fixed in place on the webs 18, 18a without any other special means.

A slightly resilient cover member 16 holds the clamping plate 11.26 in the clamped position.

This is because the repulsive force of the cover member 16
1.26 as protrusions 10, 10a and 23, 23a, respectively
This is because it is pushed towards the

Other additional means of joining the joints may be modified without departing from the spirit and scope of the invention.
