Description

A multi-function beam clamp

The present invention relates to a multifunctional beam clamp, and more particularly, to a multifunctional beam clamp which can be clamped to various angular supports while being firmly coupled to beams installed at various angles, .

Generally, beams of H-shaped or I-shaped steel are used as main frames for supporting buildings in various industrial sites or construction sites.

After the beam is installed, the ceiling panel is slab or wall formed outwardly of the beam, and various piping pipes, wires or ducts installed in the building are installed inside the ceiling panel.

A beam clamp is applied as a connecting member to fix such facilities along the beam.

Since the clamp of the prior art is horseshoe-shaped, the beam is inserted into the open end side, and the clamping force of the bolt As shown in Fig.

However, such prior art beam clamps have problems in that when the impact or vibration from the outside is transmitted to the beam or beam clamp, the bolt fastening force is gradually weakened and the coupling force with the beam is lowered. Since the hanger can be mounted only in the direction perpendicular to the beam, there is a closed end where the beam is installed, that is, depending on the vertical or horizontal or inclined structure, a different clamping means must be used.

Hereinafter, a preferred embodiment of a multifunctional beam clamp according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a multifunctional beam clamp according to the present invention. As shown in FIG. 1, the present invention mainly includes a body 10, a first hanger 20, and a second hanger 30.

The body 10 includes the upper body 11, the lower body 12, the shaft bolt 13, the nut 14 and the adjustment bolt 15 in combination.

The upper body (11) and the lower body (12) are provided so as to open in the mutually facing directions in the upper part and the lower part.

That is, the upper body 11 and the lower body 12 have a shape such that the inside thereof is opened in a direction opposite to each other, while the outer circumferential edges protrude at a predetermined height so as to face each other.

A plurality of reinforcing protrusions 110 and 120 are formed on the upper surface of the upper body 11 and the lower surface of the lower body 12 corresponding to each other.

A shaft bolt 13 is vertically penetrated to be axially engaged with the upper body 11 and the lower body 12 at a middle portion between the upper body 11 and the lower body 12, 13 to fasten the nut 14 such that the upper body 11 and the lower body 12 are interconnected.

The guide protrusions 121 are formed at the upper ends of the outer circumferences on both sides so that the width between both side surfaces is smaller than the width of the upper body 12 at the rear of the lower body 12 to which the shaft bolts 13 are connected, A guide hole 111 through which the guide protrusion 121 can pass is formed in the upper body 11 on the same vertical line.

The adjustment bolt 15 is screwed vertically through the lower body 12 at the rear of the same horizontal line as the shaft bolt 13 so that the adjustment bolt 15 contacts the upper body at the upper end.

On the other hand, the teeth 112 and 122 are formed symmetrically with respect to each other on the outer peripheral edge section of the front side facing the shaft bolt 13 connecting the upper body 11 and the lower body 12 .

Therefore, the upper body 11 and the lower body 12 are formed to have the same size in which the front teeth forming the teeth 112 and 122 are mutually symmetrical with respect to the portion where the shaft bolts 13 are coupled, The width of the rear portion of the lower body 12 is smaller than that of the upper body 11, and the length of the rear end portion of the lower body 12 is also short.

2, the bolts 13 of the upper body 11 and the lower body 12 penetrate the bolts 13 and the bolts 13 of the bolts 13 oppose the bolts 14, So that the uneven surface 16 is formed.

At this time, the uneven surface 16 has a shape in which the inclined surfaces for gradually increasing the height in the direction of rotation in one direction are continuously formed at a certain angle. The uneven surface 16 (see FIG. 1) formed on the upper body 11 and the lower body 12 Is formed to be opposite to the uneven surface 16 formed on the nut 14 in the inclined plane forming direction.

The upper body 11 and the lower body 12 of the body 10 are connected with the bolts 13 by a combination of the nuts 14 and the adjusting bolts 15, The teeth 112 of the upper body 11 and the teeth 122 of the lower body 12 are formed so that the teeth 112 and 122 are formed at the front and the guide holes 111 and the guide protrusions 121 are formed at the rear. The configuration for firmly fixing the beam to one side of the flange surface of the beam is incompatible with the configuration of the applicant's original invention (Patent Application No. 2013-0036090).

In this configuration, hanger of various shapes is connected to the lower end portion of the shaft bolt 13 so that facilities such as pipes or wiring pipes or ducts are connected.

However, the present invention is characterized in that facilities formed in various directions in the above-described configuration are stably supported by the first hanger (20) and the second hanger (30).

The first hanger (20) of the present invention is configured to be able to rotate at various angles at the tip of the lower body (12).

3 is an exploded perspective view illustrating a first hanger of a multifunctional beam clamp according to the present invention.

1, the first hanger 20 includes a hanger shaft 21, a connecting band 22, and a first bolt 23.

The hanger shaft 21 of the first hanger 20 is vertically penetrated from the upper portion of the lower body 12 and the upper end of the hanger shaft 21 is connected to the lower body 12 so as to be rotatable in the radial direction And a connecting band 22 is axially supported at a lower end of the hanger shaft 21 so as to be rotatable up and down by a first bolt 23 at a predetermined height.

In more detail, the hanger shaft 21 is made of a flat plate having a predetermined height and a predetermined thickness at the bottom, and holes having a predetermined diameter are formed horizontally through the flat plate.

The upper end of the connecting band 22 is connected to the hanger shaft 21. The connecting band 22 is formed by separating the upper end of the lower side having a triangle or circular shape into a predetermined width, The first bolt 23 is inserted into the hanger shaft 21 through the holes so as to form holes having the same size as the holes formed in the lower portion of the hanger shaft 21, And the connection band 22 are connected to each other.

At this time, a spiral is integrally formed at one end surface side hole of the connection band 22 which is in close contact with one side surface of the hanger shaft 21, so that the hanger shaft 21 and the hanger shaft 21 are fastened with the first bolt 23, The connecting band 22 can be stably connected or the nut can be fastened and connected.

The connecting band 22 can be moved in the vertical direction by the first bolt 23 axially coupled to the hanger shaft 21 in the horizontal direction while allowing the upper end of the hanger shaft 21 to rotate in the radial direction, So that the first hanger 20 can be rotated in any direction.

However, another connecting means such as a bolt is used to form a bolt fastening hole 24 at the lower end of the connecting band 22, or a separate hanger having a bolt formed at the upper end is connected.

The second hanger 30 is connected to the rear end of the upper body 11, unlike the first hanger 20 provided at the tip side of the lower body 12. [

4 is an exploded perspective view illustrating a second hanger of a multifunctional beam clamp according to the present invention.

As shown in the figure, the second hanger 30 has a configuration in which the upper end portion is bent in a horizontal direction.

That is, the second hanger 30 is formed as a horizontal bent portion 31 and a vertical bent portion 32 at the upper end portion.

The vertical bent portion 32 is vertically bent from the rear end of the horizontal bent portion 31 to the upper body 11 So that a part of the upper part is closely attached to the inner rear end surface of the lower body 12.

At this time, the adjustment bolt 15 screwed vertically through the lower body 12 causes the upper end portion to be closely attached to the bottom surface of the horizontal bent portion 32 of the second hanger 30. [

A hole is formed in the vertical bent portion 32 positioned at the rear of the lower body 12 while being closely attached to the rear end surface of the upper body 11 so that the outer peripheral edge of the rear end side of the upper body 11 can be horizontally passed through at the same time So that one end of the second bolt 33 is threaded so that a spiral is formed on the inner circumferential surface of the hole at the side of the vertical bent portion 32 of the hole and the lower vertical bent portion 32 of the hole screwed to the second bolt 33 Holes for allowing one end of the third bolt 34 to pass therethrough are formed.

Accordingly, the second bolt 33 is screwed into the hole forming the spiral in the vertical bent portion 32, but the third bolt 34 is fixed to the end portion passing through the vertical bent portion 32 by fastening the nut .

The lower surface of the vertical bending portion 32, which is in close contact with the upper body 11, is formed into a circular arc having a predetermined width. An angle adjusting hole 320 is formed in the circular arc surface, .

The third bolt 34 is connected to the angle adjusting hole 320 in the same manner as the second bolt 33 while the washer holder 35 is axially coupled to the third bolt 34 and the vertical bent portion 32 is coupled to the third bolt 34. [ The nut is fastened to an end portion of the through hole 320 through which the angle adjustment hole 320 passes.

It is more preferable that the arc-shaped plate surface extending to the lower portion of the upper body 11 is provided on the same vertical line as the outer peripheral surface of the rear end of the upper body 11.

The second bolt 33 and the third bolt 34 are screwed to the vertical bent portion 32 and the vertical bent portion 32 and the third bolt 34 are screwed to the head portion side of the second bolt 33 and the third bolt 34, 32 are spaced apart from each other by a width equal to or greater than the thickness of the plate material to be supported so that the both ends are bent.

Accordingly, the square tube or channel is fixed by the second holder 30, and in particular, the groove can be fixed to the beam 40 in the vertical direction.

The second bolt 33 and the third bolt 34 are axially fixed through a rectangular pipe or channel between the vertical bent portion 32 of the second holder 30 and the washer holder 35, In this case, the third bolt 34, which is pivotally supported through the angle adjusting hole 320 of the vertical bent portion 32, is rotated and fixed at a required angle in the angle adjusting hole 320, Ensure that square pipes and channels are secured securely.

The operation of the multifunctional beam clamp according to the present invention will now be described.

FIG. 5 is an assembled perspective view of a multifunctional beam clamp according to the present invention, and FIG. 6 is an assembled cross-sectional view of a multifunctional beam clamp according to the present invention.

The multifunctional beam clamp of the present invention is configured to be fixed to one side of an I beam or H beam as in the prior invention of the present invention.

7, the upper body 11 and the lower body 12 are connected to each other by the bolts 13 and the nut 14, and the adjusting bolt 15 is attached to the lower body 12 Conclude.

The beam 40 is inserted between the upper body 11 and the teeth 112 of the lower body 12 to the cross bar 41 on one side of the H beam and the nut 14 is operated, The teeth 112 of the upper body 11 and the lower body 12 are brought into contact with the upper and lower surfaces of the crosspiece 41. [

That is, when the rear adjustment bolt 15 is rotated to one side in a state in which one side upper surface and the lower side of the beam crossbar 41 are simultaneously in contact with the teeth 112 of the upper body 11 and the lower body 12 The adjusting bolt 15 screwed to the lower body 12 is raised toward the upper body 11 and pushes up the rear of the upper body 11. [

The distance between the teeth 112 and 122 of the upper body 11 and the teeth 112 and 122 of the lower body 12 in contact with the beam crossbar 41 on the opposite side of the adjusting bolt 15 with respect to the position where the shaft bolt 13 is engaged, The pressure is applied in the direction in which it is further narrowed, so that the coupling force with the cross bar 41 is increased.

Particularly, since the upper and lower bodies 11 and 12 are formed on the same vertical line with the teeth 112 and 122 formed on the mutually facing outer circumferential end faces, the pressing force applied while being in close contact with the crosspiece 41 is more concentrated The coupling force with the cross bar 41 can be further increased.

When the upper surface of the upper body 11 in close contact with the upper end of the adjustment bolt 15 is pushed up by the rotation operation of the adjustment bolt 15 as described above, the adjustment bolt 15 The gap between the upper body 11 and the lower body 12 is further increased so that the teeth 112 and 122 of the upper body 11 and the lower body 12 corresponding to the portion to which the adjustment bolt 15 is connected are formed The gap between the upper end side body 11 and the lower body 12 becomes gradually narrower.

Therefore, when the adjusting bolt 15 is rotated in one direction, the body body 10 is made stronger by the indentations 112 and 122 of the upper body 11 and the lower body 12, So that it can be fixed to the cross bar 41.

The fixing of the body 10 by the leverage can not only improve the coupling force with the cross bar 41 as described in the foregoing description of the invention, but also allow the teeth 112, So that the bonding force between the two substrates can be stably maintained.

The shaft bolt 13 of the body 10 thus coupled is screwed to various holders having a nut hole at the lower end thereof to allow various wires and pipes or ducts to be installed in the holder.

Also, since the body 10 can be fixed to a vertical beam, a horizontal beam, or a truss beam having a predetermined inclination angle such as a ceiling, it is possible to realize the height of piping and wiring, or a more various construction angle.

8, when the body 10 is fixed to the truss beam 40 having a predetermined angle of inclination, the shaft bolt 13 of the present invention is supported by the lower body 12 The first hanger 20 can freely rotate in the radial direction of the hanger shaft 21 and the connecting band 22 connected to the hanger shaft 21 can rotate at a predetermined angle in the vertical direction as shown in FIG. It is possible not only to support various shapes of holders supported through the bolts for fastening the bolts 22 of the band 22 at various angles, but also to support the pipes to be piped and wired at various angles at desired angles There is a number.

Therefore, since the holder for towing the structure can be fixed at various angles by the first hanger 20 in the beam clamp of the present invention, it is not necessary to prepare various kinds of clamps according to the forming angle of the beam 40.

The axial bolt 13 connecting between the upper body 11 and the lower body 12 is formed so as to intersect with the beam 40 even when the body 10 is to be fixed to the beam 40 having a predetermined inclination angle. The support angle of the structure is very limited by the shaft bolt 13, but the first hanger 20 can be formed in a more diverse angle with respect to the hanger shaft 21 with respect to the connecting band 22, It is possible to form a pipe or a wiring with a more various angle.

In addition, piping or the like may be formed in a direction perpendicular to the body 10, and such piping support is difficult to stably support through the first hanger 20 due to interference with the body 10, As shown in FIGS. 10 and 11, by using the second hanger 30. FIG.

The second hanger 30 is configured such that a square channel is fixed in a direction perpendicular to the body 10 at a rear side of the body 10 so that various piping and the like can be formed through the square channel.

As described above, according to the present invention, the piping or wiring can be formed in various angles and directions in the body 10 fixed to the beam, so that the state of the piping or wiring in the building can be further simplified, .

The body 10 can be stably installed even by inclined beams of the ceiling and even if the body 10 is inclined, the first hanger 20 and the second hanger 30 can horizontally or vertically Or wiring, but also the piping or wiring is concentrated on the beam clamp of the present invention, thereby minimizing the installation space and greatly improving the appearance.
