The present invention relates to a method of coupling and disassembling a beam structure using a clip, and more specifically, to combine a predetermined beam structure by using a clip inserted into the flange of the first beam to support the second beam or shelf structure. Or a method of disintegrating.

In modern architecture, beam is an indispensable building material, and is commonly used as a framework for pillars, beams, ceiling slabs, and wall construction.

The prior meaning of such a beam is a general term for structural rolled steel having a longer length than a cross section by rolling to form a constant cross section, and has a merit of obtaining a high strength force with a small cross section.

Therefore, it is used for a wide variety of uses in framing or civil works of large structures such as buildings and ships, and various kinds thereof are also referred to and classified as H beams, L beams, c beams, and I beams according to the cross-sectional area. . Taking a double H beam as an example, it is one of the most widely used types in which a web is connected to a part of two flanges, which are a pair of planes arranged side by side based on the shape of a cross section.

On the other hand, in general construction, the beam providing the skeletal structure is often arranged to cross in a vertical and horizontal direction, in particular, by crossing the separate beam or shelf structure between a plurality of upright beams to utilize as a work stand or a separate step by the operator. After using the equipment as a supporter, the demolition method is also frequently used if its role is fulfilled.

However, such a process of intersecting and fixing a separate beam between a plurality of upright beams represents a very troublesome, dangerous, unnecessary cost and time consuming problem.

That is, the third beam at a desired position between the first and second beams by a lifting means such as a tower crane, typically to cross secure the separate third beam between any two upright first and second beams. In the state of lifting and supporting the worker by directly welding at the height of the height (fixed) or fixed to the ground, or by welding the bracket to the joint of the first and second beams and the third beam on the ground, respectively, the first and second The two beams are erected, and likewise, the worker fastens the bolts and the like at a height while the third beam is lifted and supported by a lifting means such as a tower crane.

Therefore, the worker has to carry out welding or bolting one by one, which wastes time and manpower. Also, when the third beam is fixed at a high position from the ground, the worker has to work at a high place for a long time. The risk is also very large.

In addition, the process is more complicated when the third beam cross-fixed between the first and second beams is removed through the above method, and the above problems are repeated again in the process of cutting the welding part or loosening the bolts one by one. Done.

Accordingly, the present invention has been made to solve the above problems, effectively cross-fixing another beam to an upright beam or to mount a separate shelf structure or effectively the effort and effort required for its disassembly process Its purpose is to present specific measures that can save money, save time and money, and enable safer and more convenient work.

In order to achieve the above object, the present invention provides a clip main body in which the second and third planar portions at both ends are bent in the same direction with respect to an intermediate first planar portion, and interposed on inner surfaces of the second and third planar portions, respectively. A method of joining a beam structure using clips including first and second leaf springs and a locking end projecting outwardly from the third planar portion, the method comprising: a) the first and second flanges on the inner and outer surfaces of an upright first beam; Inserting one or more clips so that the two leaf springs are in close contact with each other; b) providing a beam structure coupling method using a clip comprising the step of supporting a portion of the second beam or shelf structure on the engaging end provided in the at least one clip.

The present invention also provides a method of decomposing a beam structure coupled by the method according to the above description, comprising the steps of: a) lifting and removing the second beam or shelf structure; b) providing a method of disassembling a beam structure using a clip, wherein each of the at least one clip is detached from a flange of the first beam.

In this case, the clip further includes a detachable wire fixed to the second leaf spring one point in close contact with the outer surface of the flange, and a detachable groove provided through the third planar portion to expose the detachable wire to the outside. B)) pulling the detachable wire away from the third planar portion; and b '') removing the clip out of the flange.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 and 2 are respectively a perspective view and an exploded perspective view of the beam fixing clip 2 (hereinafter simply referred to as clip 2) according to the present invention, which is at least one fixed to any beam by It provides a stage on which another beam or other shelf structure can be mounted. In this case, the shelf structure is used to include all elements, such as plywood, which are fixed in a direction crossing the upright beam so that a worker or a separate equipment can be supported.

To this end, there are two main parts to be considered, firstly, the clip 2 according to the present invention is tightly fixed to an arbitrary beam so that it can sufficiently bear the load of another beam or shelf structure mounted on itself. The second is to provide a stable stage on which another beam or shelf structure can be mounted.

The content for satisfying the first of the first can be confirmed through the structure of the clip (2) according to the present invention, assuming that the part to which the clip (2) is fitted, for example, the flange of the beam, it is inserted from the end of the closely In order to be secured, the clips 2 according to the invention are bent in the same direction from their both edges about the middle first planar portion 12 so as to be in close contact with the inner and outer surfaces of the flange respectively; First and second leaf springs 22 and 24 interposed between the clip body 10 having the flat portions 14 and 16 and the inner surfaces of the second and third flat portions 14 and 16 facing each other, respectively. It includes, and from the third planar portion 16 of the clip main body 10 in close contact with the flange outer surface of the double beam, the locking end 30 that can be supported by another beam or other shelf structure is projected outwardly It is characterized by.

More specifically, the clip 2 according to the present invention has a cross-sectional shape perpendicular to the longitudinal direction of the shape of a c-shape in which one direction is opened. 12) the second and third planar portions 14 and 16 are in close contact with the ends of the flanges, and the restoring force is to be brought into close contact with each other by the inner and outer surfaces of the flanges. In this case, in order to obtain a stronger restoring force, the clip body 10 is preferably made of carbon steel or alloy steel having a relatively high carbon content. As a result, the clip 2 according to the present invention is fitted from the flange outer side of the beam to be wrapped around the corresponding part. It shows form.

A first leaf spring 22 is interposed between the second flat portion 14 of the clip body 10 and the inner surface of the flange, and a second leaf spring is disposed between the third flat portion 16 and the outer surface of the flange. 24 are interposed therebetween. In this case, the second planar portion 14 and the third planar portion 16 are bent at an angle so as to be perpendicular to each other from the first planar portion 12 of the clip body 10, and Along the ends of the second and third planar portions 14 and 16, first and second locking jaws 15 and 17 that are bent in a direction facing each other may be provided, through which the first leaf spring ( 22 is compressed at both ends by the connection points of the first and second planar portions 12 and 14 and the first engaging jaw 15, and the second leaf spring 24 is connected to the first and third planar portions 12. Both ends are compressed by the connection point of the (16) and the second locking step (17).

As a result, the first and second leaf springs 22 and 24 exert elastic force to push away from each other.

Accordingly, when the clip 2 is fitted to the flange of the beam, two kinds of forces are applied to fix the part closely, so that the second and third planar portions 14 and 16 of the clip body 10 are brought close to each other. Is the restoring force and the elastic force that the first and second leaf springs 22 and 24 are to be separated from each other.

In this case, the first and second leaf springs 22 and 24 may each have a curved shape so as to be in close contact with the inner and outer surfaces of the flange one or more times, thereby increasing the contact area with respect to the flange and thus causing the clip 2 to slip. The phenomenon can be prevented. In this case, in particular, the curved shapes of the first and second leaf springs 22 and 24 are preferably mutually symmetrical with respect to the flange of the beam as shown in the drawing, which is expected to have a stronger elastic and frictional force, This is to reduce the effort required in removing (2).

In other words, the clip 2 according to the present invention is another feature that has a configuration that can reduce the effort required for its removal, for this purpose, among the second leaf spring (24) interposed to the flange outer surface side for this purpose The detachable wire 44 is fixedly coupled to the point of direct contact with the flange outer surface, and the detachable groove 42 is attached to the third flat portion 16 of the clip body 10 to expose the detachable wire 44 to the outside. ) Is provided.

In more detail, the first and second leaf springs 22 and 24 of the clip 2 according to the present invention are bent to be in close contact with the inner and outer surfaces of the flange at least once, and the curved shapes thereof The first and second leaf springs 22 and 24 are in close contact with each other in the same position with respect to the inner and outer surfaces of the flange of the beam. In addition, the fixing wire 44 is fixedly coupled to a point in which the double plate spring 24 is in direct contact with the outer surface of the flange, and then a detachable groove (3) in the third flat portion 16 of the clip body 10 corresponding thereto. 42 is provided to expose the detachable wire 44. When the clip 2, which is pre-coupled to the flange of the beam, is removed if necessary, the third planar portion of the clip body 10 ( 16, the curved shape of the second leaf spring 24 is modified by pulling the detachable wire 44 exposed to the outside through the detachable groove 42 provided in the same manner as the first leaf spring 22. It can be deformed into a curved shape, whereby the elastic force of the first and second leaf springs 22 and 24 applied to the flange of the beam can be relatively reduced, making it easier to remove the clip.

In this case, the detachable wire 44 is fixedly coupled to the point of close contact with the inner surface of the flange of the beam in the first leaf spring 22, and the detachable groove 42 penetrates through the detachable groove 42 through the corresponding second flat portion 14. The same effect can be expected when the detachable wire 44 is exposed, but the detachable wire 44 is fixed to the second leaf spring 24 to be removed from the flange outer surface of the beam without any obstruction. The detachable groove 42 is positioned in the portion 16.

In addition, when referring to the drawings including the above description, the point where the second leaf spring 24 and the flange outer surface of the beam closely contact each other can easily be expected to exhibit a line shape, in which case the second leaf spring 24 ), A pair of wire holes 26 are perforated at two different points of the line shape closely contacted to the flange outer surface of the beam, and then both ends of the detachable wire 44 are bent into a hook shape. It can be easily fixed by being inserted into the wire hole 26.

3A and 3B are schematic diagrams illustrating a disassembly method of the clip according to the present invention, respectively. First, the flange of the second leaf spring 24 of the clip 2 mounted as shown in FIG. F) is pulled by the detachable wire 44 fixed to the point in close contact with the direct, as a result, the bending form of the second leaf spring 24 is deformed as shown in Figure 3b, the same bending as the first leaf spring 22 It shows shape.

Thereby, the pressure applied to the flange F of the beam is reduced, and the clip can be easily removed.

Referring again to FIGS. 1 and 2, the clip 2 according to the invention is tightly coupled to the flange of any beam to provide a stage on which another beam or a predetermined shelf structure can be mounted and supported. The locking end 30 protrudes outward from the third plane portion 16 of the clip body 10 positioned on the flange outer surface side of the beam, which extends the upper end of the third plane portion 16 to a predetermined length. It can be completed simply by bending it outward with respect to the flange.

At this time, the area and shape of the locking end 30 may be appropriately adjusted in consideration of the load and area of another beam-bearing shelf structure supported on the upper portion thereof, and although not separately shown in the drawings, the locking end ( It is also possible to fasten the bolt is inserted into another beam or shelf structure that is supported by mounting the bolt hole in the hole 30 on the support 30 from this of course.

4 is a process perspective view for explaining a method of combining and disassembling the beam using the clip 2 according to the present invention. For convenience, a middle of two upright first and second H beams H1 and H2 is illustrated. A case where another third H beam H3 is crossed at a point is shown.

As shown there is provided a pair of flanges F1, F2 facing each other from the first and second H beams H1, H2, respectively, and the first and second H beams H1, H2 facing each other. After fixing the clips 2 according to the present invention to the flanges (F1, F2) of each of the third H beam (H3) above the locking end 30 protruding from each other in the direction facing each other from these clips (2) Put on). The third H beam H3 may serve as a support for supporting a workbench or equipment when an operator steps on it, and when the third role is performed, the third H beam H3 may be disassembled in the reverse order of installation.

At this time, the disassembly method in more detail, as described above, pull the detachable wire 44 of the clip 2 away from the third planar portion 16 of the clip body 10 and then the entire clip 2 It is pulled out of each flange (F1, F2).

In the above drawings, although a total of eight clips 2 are used, four for each of the first and second H beams H1 and H2, the three H beams H3 mounted on and supported by the hanging ends 30 of the first and second H beams H1 and H2 are used. The number of clips 2 can be appropriately adjusted in consideration of the load or the area, and for the convenience of construction, a total of four clips at the top of the target positions of the first and second H beams H1 and H2, respectively, respectively. (2), and after fixing it, the 3rd H beam H3 is supported on these locking ends 30, and if necessary, the lower end of the target position of the 1st and 2nd H beam H1, H2 is respectively required. Of course, a total of four clips 2 each can be additionally inserted and reinforced.

In addition, the above drawings are only examples of the use of the clip 2 according to the present invention, as long as the object to which the clip 2 according to the present invention is fitted is provided with flanges F1 and F2 or corresponding elements. It will be apparent to those skilled in the art that there is no reason to be limited to the H beam, and that the support mounted by the clip according to the present invention also need not be limited to the H beam.

Using the clip according to the present invention as described above, it is possible to effectively reduce the effort and effort required when cross-fixing another beam to an arbitrary upright beam or mounting a separate shelf structure or its disassembly process This has the advantage of saving money and time and allowing safer and more convenient operation.

In other words, the clip according to the present invention does not require a welding or bolting process, so the overall process is very simple and can be performed with a small manpower in a short time.
