Description

REMOVABLE JOINT SYSTEM BY STAPLES FOR BEAMS PROFILE METAL CLASSES FITTED BY THE TOP

SECTOR OF THE TECHNIQUE

The present invention relates to a removable joining system of type 1 metal profiles, applied to the manufacture and assembly of removable and reconfigurable metal structures. by using standard steel profiles.

BACKGROUND OF THE INVENTION

At present, practically all the unions used in the manufacture of metal structures with standard steel profiles, use the welding joint or the classic screw connections.

In the first case, the welded joints have the great disadvantage that they are not removable or reconfigurable; its dismantling generally implies its destruction, with the inconvenience that this entails.

Classic screw connections, on the other hand, need a previous preparation of the profiles to be joined. Operations involving plate welding, stiffening of profile souls, drilling of profiles, etc. are necessary. This type of manufacturing is generally carried out for very specific configurations, so it is only useful for cases that were designed.

In summary, with the unions currently used in the manufacture of metallic structures, welding and cranked joints, there is no possibility of reconfiguring the structure taking advantage of all the components of the system, including the profiles to be joined.

A removable system for type 1 metal profiles, in which no previous preparation of the profiles is necessary, is the one that uses joining clips. The use of these clips as a mooring of the profiles is frequent in profiles of profiles. In addition, it must be taken into account that for the connections of the profiles, depending on the design and the method of execution of the joint, different types of resulting behavior can be achieved. of the Union. It can behave as an articulated, rigid or semi-rigid joint, depending on the bending moment it is capable of transmitting.

With the use of staples, which are shown below, it is sought that the union of different sizes of standard profiles I be possible, more specifically in the case of beam-beam joints flush with the top, without requiring previous preparation operations on the profiles and allowing the joints obtained to be completely removable and reusable. The only operation necessary to perform, using joining systems with fixing clips, washers and standard screws, is the cutting of the profiles to the necessary extent. In addition, with the use of the proposed staple system, an articulated or rigid / semi-rigid knot can be conceived easily and reversibly, depending on the moment that is capable of transmitting / absorbing the profiles involved in the joint.

There are currently disclosures of removable joint systems for standard type 1 steel profiles, such as ES2432915B2. However, when it comes to beams flush at the top, there is no known system that meets the following characteristics: a) that does not need prior preparation of the profiles to be joined, b) that is completely removable and reconfigurable, e) that the same elements used for the union are valid for different sizes of profiles 1, d) that allows to regulate the height exactly to keep the beams flush with the top.

DESCRIPTION OF THE INVENTION

To solve the drawbacks described above, the present invention (Figure 1) consists in the use of a main support plate (1, see Figure 2) and a secondary support plate (2, see Figure 3). Both plates are provided with torn ones (3,4) that make it possible to join different sizes of standard I profiles.

To make the joining of the profiles, in addition to the main support plate is needed

(1) and the secondary support plate (2), fixing clips (5, see Figure 1) with their thymes (6), nuts (7) and corresponding washers (8). With this system you

would make the connection of the beam-beam type flush at the top, using to

it standardized metal profiles of type l.

The tears (3) on the main support plate (1) and the tears (4) on the plate

Secondary support (2), allow the adjustment of the staples and their lomillería. in both

Wing sides of different sizes of profiles to be joined (see Figure 4).

The main support plate (1, see Figure 2) that is attached to the main beam (9) is

provided with side flanges (10) that are welded in the center of the plate by thin sheets (17) and these side flanges are torn

(11), which allow the height to be adjusted for different sizes of metal profiles,

when this plate is mounted on the secondary support plate (2) (see Figure 5). This assembly is possible because the secondary support plate (2, see Figure 3) is

provided with flanges (13), in which some drills (14) have been made, which allow using clamps (15), nuts (20) and washers (22), the attachment to the plate main support (1) through the torn ones (11). Other adjustment loins (16), which are placed in the threads (21) of the

main support plate (1), allow to push the tabs (13) of the support plate

secondary (2) and, as a consequence, accurately adjust the height of the beam

secondary (12) with respect to the main beam (9) (see Figure 6).

When the main beam (9) and the secondary beam (12) are flush with precision from the top, the tightening bolts (15), nuts (20) and

washers (22) (see Figure 6).

To prevent torsional stresses in the main beam (9), the

stresses due to the secondary beam (12), are transmitted through the thin sheets (17) of the main support plate (1, see Figure 2). which are centered on the core of the main beam (9) (see Figure 5). Because you are

Thin sheets (17) are easily deformable, allowing not to transmit

F1ector moments from the secondary beam (12) to the main beam (9), which would involve torsional stresses in the main beam (9).

For cases in which if you want to transmit the bending efforts of the beam secondary (12) to the main beam (9), the stiffening knives (18) would be placed on the holes (19) of the main support plate (1) (see Figure 6).

PREFERRED EMBODIMENT OF THE INVENTION

Below is a description of the embodiment of the invention, making reference to the numbering adopted in the figures.

First, the main support plate (1) is placed under the main beam (9) and the plate is attached to the wings of the copper using the corresponding clips (5) and their corresponding screws (6), nuts (7) and washers (8). ) (see Figure 7).

To solve this assembly, a clip (5) is fastened with its hardware (6) and once the size of the corresponding profile wing is adjusted, it is placed under the nut

(7) flat washer (8) support. All this is careful to leave the main support plate (1) aligned with the wings of the profile and bringing the screws (6) of the fixing clips (5) to the edge of the profile to the maximum. This operation is repeated on each tear (3) and once done, firmly tighten all screws (6).

(16).

Then we place the secondary support plate (2) under the secondary beam (12) and the plate is tied to the wings of the profile following the same operations as in the previous case (see Figure 8).

The next step is to approach the two beams, with their corresponding plates mounted

and when the tears (11) of the main support plate (1) are aligned, with the

10 holes (14) of the secondary support plate (2) (see Figure 5), the clamping screws (15) are inserted; through the holes (14) and torn (11), but they are left loose to be able to adjust the height with other adjustment knives (16). Once

the main beam (9) and the secondary beam (12) are flush with precision from the top, the clamping screws (15) are firmly tightened (see Figure 6). fifteen

Then, if we want the secondary moments of the secondary beam to be transmitted

(12), which is transformed into torsion on the main beam (9), the stiffening screws (18) are introduced on the holes (19) of the main support plate (1) (see Figure 6).
