[0002] The light steel keel is a new type of building material, which has the effects of light weight, high strength, earthquake resistance, sound insulation, constant temperature, etc. At the same time, it also has the advantages of short construction period and simple construction. Therefore, the light steel keel is widely used in places such as airport terminals, amusement parks, shopping malls, factories, interior decoration settings, ceilings, etc. During the erection of the light steel keel, sometimes two light steel keels need to be connected in a vertical state, especially at the top and side connections of buildings, and the vertical connection between the horizontal support keel and the vertical support keel. In these vertical connections, the common connection method is generally to directly use fastening bolts for connection, which can also achieve a good connection effect.

[0003] However, using fastening bolts for connection will cause the positions of the horizontal keel and the longitudinal keel to be unable to be adjusted flexibly. When there is a deviation in the opening of the bolt holes, it is necessary to re-open the holes for installation, and the actual connection is rather troublesome.

[0004] Therefore, it is necessary to provide a new vertical connection structure of light steel keels to solve the above technical problems. Content of the Utility Model

Specific embodiments

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Please refer to Figure 1-Figure 7 . The vertical connection structure of the light steel keel includes: a transverse keel 1 and a longitudinal keel 2. The top of the longitudinal keel 2 extends into the transverse keel 1 and contacts the inner wall of the top of the transverse keel 1. A first clamping plate 3 and a second clamping plate 4 are fixedly installed on the inner wall of the top of the transverse keel 1. A through groove 5 is formed in the first clamping plate 3, a blind groove 6 is formed in the second clamping plate 4, and a same plug-in board 7 is arranged in the through groove 5 and the blind groove 6. The plug-in board 7 penetrates through the longitudinal keel 2 and is slidably connected with the longitudinal keel 2, so that the longitudinal keel can be restricted within the transverse keel 1. In order to fix the longitudinal keel 2 at a specified position, a plurality of retaining sunk holes 8 are formed at the bottom of the plug-in board 7. A C-shaped mounting bracket 11 is fixedly installed on the outer wall of one side of the longitudinal keel 2. A guiding slide bar 12 is slidably installed on its top. The top of the guiding slide bar 12 is fixedly installed with a connecting piece 13. Two plug pins 14 are fixedly installed on the top of the connecting piece 13. The tops of the two plug pins 14 both extend into the corresponding retaining sunk holes 8. By means of the plugging connection between the two, the longitudinal keel 2 is reliably fixed within the transverse keel 1.

[0024] In the above method, in order to ensure that the bolt 14 can be firmly inserted into the retaining sunk hole 8, a wedge-shaped linkage block 15 is fixedly installed at the bottom end of the guiding slide bar 12. The wedge-shaped linkage block 15 is a common wedge-shaped structural part on the market and has a bevel edge. A return spring 16 is sleeved on the guiding slide bar 12. Its top end is fixedly connected to the inner wall of the top of the C-shaped mounting frame 11, and its bottom end is fixedly connected to the wedge-shaped linkage block 15. A fastening screw rod 17 is threadedly installed on one side of the C-shaped mounting frame 11 away from the longitudinal keel 2. A guiding slide plate 18 is rotatably installed at one end of the fastening screw rod 17 close to the longitudinal keel 2. The guiding slide plate 18 abuts against the bevel edge of the wedge-shaped linkage block 15. Through the close abutment between the guiding slide plate 18 and the wedge-shaped linkage block 15, the bolt 14 is continuously and stably inserted into the retaining sunk hole 8. In addition, a spring washer 19 is sleeved on the fastening screw rod 17, and an anti-slip screwing head is fixedly installed at one end of the fastening screw rod 17 away from the longitudinal keel 2. Both sides of the provided spring washer 19 abut against the anti-slip screwing head and the outer wall of one side of the C-shaped mounting frame 11 respectively. The spring washer 19 can provide a thread pre-tightening force for the fastening screw rod 17 so that it will not easily rotate and loosen. Two limiting cross bars are fixedly installed on one side of the C-shaped mounting frame 11 away from the longitudinal keel 2. Both ends of the two limiting cross bars close to the longitudinal keel 2 are fixedly connected to the guiding slide plate 18. In this way, when the fastening screw rod 17 is rotated, the guiding slide plate 18 can only move linearly.

[0025] In this method, in order to fix the plug-in board 7 on the first clamping board 3 and the second clamping board 4, a cross platform 9 is fixedly installed on one side of the first clamping board 3 away from the second clamping board 4. A half-thread screw rod 10 is slidably installed thereon. The half-thread screw rod 10 penetrates through the plug-in board 7 and is slidably connected to the plug-in board 7. A nut is threadedly sleeved on the half-thread screw rod 10, and the nut contacts the top of the plug-in board 7, thereby forming a fixing function.

[0026] In this method, in order to ensure that the plug-in board 7 does not loosen, a rectangular sliding opening is formed on the longitudinal keel 2. The plug-in board 7 penetrates through the rectangular sliding opening and contacts the inner wall of the rectangular sliding opening.

[0027] The working principle of the vertical connection structure of the light steel keel provided by the present utility model is as follows:

[0028] In the initial state, the transverse keel 1 and the longitudinal keel 2 have not been installed yet, and the guiding slide plate 18 and the wedge-shaped linkage block 15 do not contact, that is, the return spring 16 is in its original state;

[0029] When it is necessary to install the transverse keel 1 and the longitudinal keel 2, first screw the nut on the half-thread screw 10 and remove it from the horizontal platform 9. At this time, the plug-in plate 7 loses its fixing effect, and then it is pulled out from the through groove 5 and the blind groove 6. Then, the top of the longitudinal keel 2 is inserted into the transverse keel 1 and contacts the top inner wall of the transverse keel 1. Then, the plug-in plate 7 is inserted into the through groove 5, passes through the rectangular sliding opening on the longitudinal keel 2, and finally inserted into the blind groove 6. Then, the half-thread screw 10 is screwed on. At this time, the first step of installing the longitudinal keel 2 is completed.

[0030] Then, the longitudinal keel 2 is moved to the designated installation position, and the latch 14 is aligned with the corresponding retaining countersunk hole 8. Then, the fastening screw 17 is turned clockwise, and the guide slide 18 moves toward the wedge-shaped linkage block 15. When it contacts the oblique edge of the wedge-shaped linkage block 15, it pushes the wedge-shaped linkage block 15, causing the wedge-shaped linkage block 15 to move upward with the guide slide 12 until the anti-slip screw is tightened. At this time, the two latches 14 are respectively inserted into the corresponding retaining countersunk holes 8. At this point, the final installation operation of the longitudinal keel 2 is completed.

[0031] In later use, the pin 14 can be brought out of the retaining countersunk hole 8 by rotating the fastening screw 17 counterclockwise, and its specific installation position can be adjusted by moving the longitudinal keel 2, which is more flexible to use.

[0032] Compared with the related art, the vertical connection structure of the light steel keel provided by the utility model has the following beneficial effects:

[0033] The utility model provides a vertical connection structure of a light steel keel. By arranging a plug-in plate 7 that passes through the longitudinal keel 2 and a plurality of retaining countersunk holes 8 opened at the bottom of the plug-in plate 7, the installation position between the longitudinal keel 2 and the transverse keel 1 can be flexibly adjusted according to actual needs. The utility model has strong applicability. Moreover, when dismantling the longitudinal keel 2, it is only necessary to remove the half-thread screw 10, then pull out the plug-in plate 7, and finally rotate the fastening screw 17 to bring the pin 14 out of the retaining countersunk hole 8. The dismantling work is relatively simple and convenient for people to use and operate.
