[0029] Combine the following Figure 1 and Figure 2 The utility model describes a high-strength ceiling keel fixing clamp.

[0030] like Figure 1 As shown, in one embodiment, a high-strength ceiling keel fixing clamp has a closed end and an open end, the closed end of the fixing clamp is slidably mounted on the main keel, and the open end of the fixing clamp is buckled on the triangular keel, including a first buckle plate 100, a second buckle plate 200, a fastening plate 300, a fastening bolt 400 and a reinforcement 500.

[0031] The first gusset plate 100 is arranged parallel to the ventral side of the main keel and is located on one side adjacent to the ventral side of the main keel.

[0032] Preferably, the first clasp plate 100 is closely connected to the outer wall of the ventral side of the main keel, and the bottom end of the first clasp plate 100 has a first clasp claw 110, and the inner side end of the first clasp claw 110 is processed into a round chamfer.

[0033] The second gusset plate 200 has a reinforcing channel 202, which is arranged parallel to the ventral side of the main keel and is located on a side away from the ventral side of the main keel.

[0034] Specifically, the reinforcing channel 202 is arranged corresponding to the ventral side of the main keel, the bottom end of the second buckle plate 200 has a second buckle claw 210, and the inner side end of the second buckle claw 210 is processed into a round chamfer.

[0035] One end of the fastening plate 300 is connected to the first pinch plate 100 , and the other end thereof is connected to the second pinch plate 200 .

[0039] The reinforcement member 500 has an upper support portion 501 and a lower support portion 503 and is installed in the reinforcement channel 202. The upper support portion 501 and the lower support portion 503 abut against the inner walls of the upper and lower sides of the main keel to support the upper side of the main keel.

[0040] Specifically, when the main keel and the triangular keel are fixedly connected, the triangular keel and the main keel are first placed vertically, and then the first gusset plate 100, the fastening plate 300 and the second gusset plate 200 connected as one body are first buckled onto the main keel, and then the positions of the first gusset plate 100, the fastening plate 300 and the second gusset plate 200 are adjusted so that the first buckle claw 110 and the second buckle claw 210 located on the same side abut against one side surface of the triangular keel, and then the first buckle plate 100, the fastening plate 300 and the second buckle plate 200 are pressed down. 0 and the second buckle plate 200, so that the first buckle claw 110 and the second buckle claw 210 on the other side are engaged with the other side surface of the triangular keel. Subsequently, the reinforcement member 500 is installed into the reinforcement channel 202, and the upper support part 501 and the lower support part 503 are adjusted so that the upper support part 501 and the lower support part 503 are respectively abutted against the upper and lower inner walls of the main keel, thereby achieving effective support for the upper side of the main keel and preventing the upper side of the main keel from being deformed by the fastening bolts 400.

[0041] The high-strength ceiling keel fixing clamp of this embodiment is formed by opening a reinforcement channel 202 on the second buckle plate 200 and installing a reinforcement member 500 in the reinforcement channel 202. The bottom height of the reinforcement member 500 is supported by supporting the lower support portion 503 of the reinforcement member 500 on the lower top of the main keel, and the upper side of the main keel is supported by the upper support portion 501 of the reinforcement member 500. This can prevent the upper side of the main keel from being deformed by the fastening bolts 400, effectively protect the main keel structure, and ensure the stable connection of the ceiling structure.

[0042] like Figure 2 As shown, in one embodiment, the reinforcement channel 202 includes a mounting channel 201 and a supporting channel 203 , and the inner end of the mounting channel 201 is in communication with the supporting channel 203 .

[0043] In this embodiment, the installation channel 201 is arranged along the length direction of the main keel, the support channel 203 is arranged perpendicular to the installation channel 201 , and the reinforcement member 500 enters the support channel 203 through the installation channel 201 .

[0044] In this embodiment, the reinforcement member 500 includes an adjustment handle 510, an adjustment screw 520, an upper support end block 530, and a lower support end block 540 (see Figure 1 ), the adjusting screw 520 is installed on the adjusting handle 510, the upper supporting end block 530 is installed on the top end of the adjusting screw 520, and the lower supporting end block 540 is installed on the bottom end of the adjusting screw 520.

[0045] Specifically, the width of the installation channel 201 along the height direction is greater than the sum of the thicknesses of the upper support end block 530, the adjustment handle 510 and the lower support end block 540, the width of the support channel 203 along the horizontal direction matches the widths of the upper support end block 530 and the lower support end block 540, and the adjustment screw 520 is installed at one end of the upper support end block 530 and the lower support end block 540 that is away from the main keel.

[0046] In this embodiment, the adjusting screw 520 includes an upper screw 522 and a lower screw 524. The upper screw 522 and the lower screw 524 are of equal length, and the spiral grooves of the two have opposite rotation directions. The upper screw 522 and the lower screw 524 are respectively fixedly mounted on the top and bottom of the adjusting handle 510.

[0047] In this embodiment, the upper support end block 530 is threadedly installed on the upper screw rod 522, and the lower support end block 540 is threadedly installed on the lower screw rod 524. The upper support end block 530 and the lower support end block 540 are symmetrically distributed above and below the adjustment handle 510.

[0048] In this embodiment, the upper support end block 530 has an upper support block 532 at the top of one end adjacent to the main keel, and the lower support end block 540 has a lower support block 542 at the bottom of one end adjacent to the main keel.

[0049] Specifically, when supporting the upper side of the main keel, first adjust the upper support end block 530 and the lower support end block 540 to fit respectively on the top and bottom of the adjusting handle 510, ensure that the upper support block 532 and the lower support block 542 are located on one side of the installation channel 201 adjacent to the main keel, and the upper screw 522 and the lower screw 524 are located on the other side of the installation channel 201, send the upper support block 532, the adjusting handle 510 and the lower support block 542 into the support channel 203 through the installation channel 201, rotate the adjusting handle 510, and the adjusting handle 510 drives the upper screw 522 and the lower screw 524 to rotate synchronously, so as to drive the upper support end block 530 to drive the upper support block 532, and drive the lower support end block 540 to drive the lower support block 542 to respectively contact the upper and lower sides of the main keel, thereby supporting the upper side of the main keel and preventing the upper side of the main keel from being deformed by being pressed.

[0050] In this embodiment, the nut side wall of the fastening bolt 400 has a plurality of groups of protrusions.

[0051] Specifically, when using fixing clamps to fix the main keel and the triangular keel, the fastening bolt 400 is generally tightened manually first. By adding multiple sets of protrusions to the side wall of the nut of the fastening bolt 400, the friction is increased, making it easier to manually pre-tighten the fastening bolt 400.

[0052] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
