DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0021] Reference Figure 1-5 A steel structure connection device for construction engineering, comprising a support column 1, an I-beam 2 and a clamping device 4, the outer wall of the support column 1 is provided with a through hole 12, and the inner wall thereof is welded with a reinforcing plate 11, the support column 1 is respectively fixed with a mounting frame 3 by bolts, the I-beam 2 is plugged into the mounting frame 3, a plug column 33 and a latch 34 are plugged into the top of the mounting frame 3, two plug columns 33 are symmetrically distributed along the latch 34, and a transverse clamping hole 21 is provided inside the I-beam 2; the support column 1 is used to provide a support point and a mounting point for the installation of the I-beam 2, and the mounting frame 3 is used to limit the installation of the I-beam 2;

[0022] The clamping device 4 includes a bidirectional screw rod 41 and a clamping plate 42. The two clamping plates 42 respectively pass through the through holes 12 and contact the inner walls of the support column 1 and the mounting frame 3. The bidirectional screw rod 41 passes through the support column 1 and is threadedly connected to the two clamping plates 42. A clamping block 421 is welded to the end of the two clamping plates 42 on one side close to each other, and the clamping block 421 is plugged into the clamping hole 21; the bidirectional screw rod 41 is used to drive the two clamping plates 42 to move closer to or away from each other, so that the clamping plates 42 are in contact with or away from the I-beam 2, so as to achieve fixed installation of the I-beam 2 or facilitate disassembly.

[0023] A vertical insertion hole 22 is opened inside the I-beam 2, and the pin 34 passes through the installation frame 3 and is inserted into the insertion hole 22; after the clamping plate 42 and the clamping block 421 lock the I-beam 2, the pin 34 is used to auxiliary fix the I-beam 2. After the clamping block 421 is plugged into the clamping hole 21, the plug column 33 can be inserted in the middle of the clamping plate 42 and the installation frame 3; when the clamping plate 42 contacts the I-beam 2, pressure can be applied to the plug column 33 to push it into the inner cavity of the installation frame 3 and place it in the middle of the clamping plate 42 and the inner wall of the installation frame 3 to prevent the end of the clamping plate 42 from separating from the I-beam 2, causing the installation of the I-beam 2 to become loose and affect the stability of the steel structure installation. A connecting plate 31 is welded to the top and bottom of the installation frame 3, and the connecting plate 31 is fixedly connected to the support column 1 by bolts. A triangular plate 32 is fixed to the angle between the installation frame 3 and the support column 1 by bolts.

A baffle 13 is welded to the outer wall of the support column 1, and the baffle 13 can contact the end of the I-beam 2. The use of the baffle 13 can leave a gap between the I-beam 2 and the support column 1, so as to facilitate the movement of the plug column 33 in the gap, so as to limit or release the restriction state of the clamping plate 42.

[0024] Working principle: first place the clamping device 4 horizontally inside the support column 1, then use bolts to assemble and fix the mounting frame 3, connecting plate 31, triangular plate 32 small accessories and the support column 1 in advance, transport the support column 1 and the I-beam 2 installed with the mounting frame 3 to the assembly site together, fix the support column 1 vertically on the ground, and then insert the two I-beams 2 horizontally into the two mounting frames 3. At this time, you only need to rotate the two-way screw rod 41, and the two-way screw rod 41 drives the two clamping plates 42 to approach each other, so that the clamping block 421 is inserted into the inside of the clamping hole 21, and then insert the column 33 vertically from the top of the mounting frame 3 into the middle of the clamping plate 42 and the inner wall of the mounting frame 3, and then insert the pin 34 from the top of the mounting frame 3 into the inside of the socket 22, so that the installation and fixation of the I-beam 2 can be completed quickly to improve the assembly efficiency of the steel structure.
