Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a device for attaching a beam to a steel column to form a weight rack.

(Prior art) Heavy racks support heavier objects such as mechanical parts than ordinary lightweight racks, so the columns and continuous beams between the left and right columns are made of hollow square steel or other material with high strength. At the same time, a wide-area end plate is used at the end of the beam to eliminate wobbling and increase stability at the attachment part of the beam to the column, and to enable secure attachment. Concatenation is in progress. However, with conventional beam attachment devices, the common method was to weld the end plates to both ends of the beam, but once the end plates were welded to both ends of the beam, they could not be removed, making transportation difficult. In such cases, the end plate protrudes at a right angle and gets in the way, which is inconvenient because it becomes bulky.Also, when painting, there are many protruding parts, which is troublesome, and furthermore, there is an effect of distortion due to welding. This not only reduces the strength of the joint, but also causes the welded part to easily separate due to the heavy support load.

(Technical Problem) Therefore, in the present invention, when attaching a beam to a support that constitutes a heavy rack, an end plate can be easily attached to the end of the beam without any welding at the assembly site, and To provide a heavy rack that can be quickly and reliably assembled without welding, is easy to assemble and disassemble, and has excellent strength.

(Technical Means) In order to solve the above-mentioned technical problem, the present invention is a heavy rack in which beams are installed between opposing left and right steel columns of hollow rectangular or square shape, and the beams are installed in rows on the outer surface of the columns. A fitting member having a mounting piece to the beam is integrally provided on an end plate having a locking pawl facing inward and downward that engages with a hollow box-shaped beam. It fits into the end opening, and the beam and the fitting member are removably fastened together with screws.

(Operation) The above technical means operates as follows. When the end plate 4 is applied so that the fitting member 3 fits into the one end opening 2d of the beam 2, the mounting piece 3
a, 3b, 3c engage with the upper side 2a of the beam 2 and the front and rear sides 2b, 2c so as to support them from the inside, and each mounting hole 5 provided on the upper side, front and rear sides and the mounting pieces 3a, 3b of the fitting member 3 , 3c are aligned with each other, and by screwing the screws 7 into these holes and tightening them, the end plate 4 is integrally attached to the end of the beam 2 in a state in which it largely protrudes vertically.

An end plate can be attached to the other end of the beam 2 using screws in the same manner as described above.

When attaching the beam 2 to the support column 1, place the end plate 4 attached to the end of the beam so that it matches the corner of the support column 1, and apply force to push it down. The end plate 4 can be tightly attached to the support column 1 by engaging with one of the engaging pieces 9 arranged in a row on the rear surface of the support column so as to wedge the end plate 4.

The end plate 4 is provided with at least two locking claws 8 on the upper and lower sides so as to be engaged with the corresponding engagement holes 9 at the same time.

By doing this, when assembling the heavy rack, it is carried disassembled to the site, and the end plates 4 are attached to both ends of the beam 2, so that the assembly can be easily and quickly done using only screws without welding. I can do it.

(Effects) As described above, the present invention separates the end plate 4 and the beam 2, and at least inserts the end plate 4 into the end opening 2d of the beam 2, and at least the upper side 2a of the beam and both the front and rear sides 2b, 2c. A fitting member 3 formed integrally with mounting pieces 3a, 3b, and 3c that engage and support the beam 2 and the fitting member 3 from the inside is attached by welding, and each mounting piece 3a, 3 of the beam 2 and the fitting member 3
b and 3c are configured to be removably fastened with screws 7, respectively, so when assembling the heavy rack, the strut, beam, and end plate are transported to the site in a disassembled state, and the end is inserted into the end opening of the beam. By fitting the fitting member fixed to the plate and fastening it with screws, it can be assembled easily and quickly without any welding work, and it can be attached to the support via the end plate with a large joint surface. Therefore, it can be installed strongly and stably in all directions, including up and down, front and back, left and right. In particular, the fitting member that fits into the end opening of the beam and is attached with screws is fastened to the three mounting pieces 3a, 3b, and 3c with screws so as to engage and support the upper side and both front and rear sides of the beam from the inside. As a result, the stability in the longitudinal and lateral directions is significantly improved, and it is possible to easily and inexpensively provide a strong, durable weight rack that does not wobble.

(Example) Although the pillar 1 is made of steel and has a square cross section, it can also be a hollow rectangular cylinder.

The beam 2 is made of steel and has a hollow box shape or, as shown in the illustrated example, a stepped hollow box shape with high bending strength.

The end plate 4 has two sides 4a, 4b formed into a right-angled L shape so as to fit into the corner of the support 1, with the fitting member 3 provided on one side 4a and the locking claw 8 provided on the other side 4b.

The fitting member 3 is made by bending both ends and the upper part of a flat steel plate at right angles to form an upper mounting piece 3a, a front and rear mounting piece 3b,
3c is integrally formed, and a long hole 19 is provided in the substrate surface 3d. Connect the board surface 3d to the end plate 4
are fixed together by welding 10 against one side 4a. Welding 10 is performed to weld the joint between the inner edge of the elongated hole 19 and the end plate 4. It can also be done by spot welding.

Among the mounting pieces 3a, 3b, and 3c of the fitting member 3, the lower mounting piece facing the upper mounting piece 3a is not provided because it is sufficient to support the load applied to the beam with the upper mounting piece 3a, but if necessary, There is no harm in setting it up. Further, the upper mounting piece 3a is provided at a position offset to the rear from the center in order to correspond to a stepped hollow box-shaped beam, but in the case of a box-shaped beam with a rectangular cross section without steps, it is provided at the center.

Figure 4 shows the framework of the heavy rack.A beam 2 is installed between the left and right columns 1, 1, and a lattice material 1 consisting of horizontal members and diagonal members is installed between the front and rear columns 1, 1'.
2 and 13 are attached to connect the four pillars into an integral structure, and a shelf board (not shown) is attached within the framework to form a weight rack.
