[0028] The present invention can be implemented with various modifications, and specific embodiments are illustrated in the drawings and described in detail. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0029] In describing each drawing, similar reference numerals have been used for similar components. In describing the present invention, detailed descriptions of related prior art are omitted if it is determined that such detailed descriptions could obscure the essence of the invention.

[0030] The present invention allows legs to be easily assembled to a tabletop and securely joined so that the legs can firmly support the tabletop.

[0031] The assembly table having a furniture fastening structure that combines vertical load, anti-shake, and durability according to the present invention is an assembly table in which a plurality of legs (20) can be detachably installed on the bottom surface of a top plate (10). As shown in FIG. 1, a top plate support frame (30) is further installed on the bottom surface of the top plate (10), and a bracket (40) connecting the legs to the top plate support frame is further installed on the upper end of the legs (20).

[0032] As shown in FIG. 10, the top plate (10) can be made in a square, rectangular, rhombus, circular, or elliptical shape, and depending on the shape of the top plate, the shape of the top plate support frame (30) installed on the bottom surface can also be different.

[0033] The above-mentioned top plate support frame (30) is made of a hollow tubular body, and the bracket is assembled at each end.

[0034] The above leg (20) was also made of a hollow tubular body to reduce weight.

[0035] The above leg (20) is an end portion that is supported on the ground at its lower end, and it is preferable to install an auxiliary foot at the lower end so that the hollow tubular end does not damage the ground on which the table is installed.

[0036] In addition, it is preferable that the above-mentioned leg (20) be composed of a body having a cross section that is square, square, rhombus, and circular.

[0037] As shown in FIG. 7, a bracket insertion groove (20g) is formed in the part facing the upper plate support frame at the top of the leg (20), so that the outer wall of the bracket (40) is fixed in close contact with this bracket insertion groove.

[0038] That is, the above bracket (40) has a cross-section “ A frame fixing groove (40g) is formed in the center, and the outer surface of the two side walls of the frame insertion groove is fitted into the bracket insertion groove (20g) formed in the leg.

[0039] The bracket, with both side walls fitted into the bracket insertion groove (20g), is fixed to the leg by welding the edges of the bracket insertion groove (20g).

[0040] The above bracket (40) is a coupling means for coupling the legs to the top plate and the top plate support frame, and as shown in FIGS. 6 and 7, a frame fixing groove (40g) into which the top plate support frame is fitted is formed so that the top plate support frame is fitted and coupled. (See FIGS. 1, 4 and 5)

[0041] Of course, as mentioned above, a bracket insertion groove (20g) is formed at the top of the leg (20) so that the outer wall of the frame fixing groove formed in the bracket is fitted and joined, and the leg is joined to the bracket.

[0042] As mentioned above, if the joint of the leg, which is connected by a bracket to the end of the top plate support frame fixed to the top plate, is weak, the leg may spread apart.

[0043] Accordingly, to strengthen the bonding force between the leg and the top plate or top plate support frame, the bracket (40) forms a frame fixing wing (42) with the end facing the leg bent toward the frame fixing groove, thereby forming a frame side wall insertion groove (42g) between the frame fixing wing and the side wall of the frame fixing groove.

[0044] That is, as shown in FIG. 4, when the two side walls of the end of the upper plate support frame are positioned to face the frame side wall insertion groove and pushed toward the center of the upper plate support frame, the two side walls of the upper plate support frame are fitted into the frame side wall insertion groove (42g), thereby more firmly connecting the bracket to the upper plate support frame.

[0045] The width of the frame fixing wing (42) is formed to be the same as the height of the hollow portion formed in the upper plate support frame, so that the frame fixing wing (42) is fitted into the upper support frame and securely connected.

[0046] In addition, a frame fixing projection (43) is formed at the end of the bracket (40) facing the upper plate support frame (30) and is bent toward the upper plate support frame, and is fixed by being inserted into a fixing hole formed in the upper plate support frame. (See FIGS. 5, 8, and 9)

[0047] Of course, as shown in FIG. 5, a hole is formed in the bottom of the frame fixing groove (40g) of the bracket, and the fixing screw is tightened so that the bracket is fixed to the top plate support frame, thereby increasing the bonding strength between the bracket and the top plate support frame.

[0048] In addition, on both side walls of the frame fixing groove formed in the bracket (40), a top plate fixing wing (41) that is bent horizontally with the top plate and fixed to the top plate may be formed.

[0049] The upper plate fixing wing (41) is installed in close contact with the bottom surface of the upper plate as shown in FIG. 1 and can be fixed by fixing screws, etc.

[0050] Accordingly, the prefabricated table of the present invention forms a right angle between the legs and the tabletop support frame installed on the underside of the tabletop, so that the legs can firmly support the tabletop, and also prevent the legs from bending as they support the force vertically (see FIG. 9).

[0051] The prefabricated table of the present invention configured as described above is used with the legs (20) assembled on the bottom surface of the tabletop as shown in FIGS. 1 and 2, and when not in use, the legs and brackets are separated as shown in FIG. 3 and stored between the tabletop support frames fixed to the tabletop, thereby reducing the space occupied by the entire disassembled prefabricated table.

[0052] The disassembled prefabricated table shown in Fig. 3 can be stored and transported by stacking it in multiple layers as shown in Fig. 13. Explanation of the symbols
