[0014] The technical solutions 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 utility model, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] Specific implementation method 1: Figure 1-3 As shown, this embodiment describes a construction scaffold connector for a building project, comprising a connecting device 1 and a fixing device 2. The connecting device 1 includes a sleeve 11. The sleeve 11 is threaded on the outside, and a boss 12 is fixedly connected to the outer circumferential surface of the sleeve 11. The inner diameter of the sleeve 11 is larger than the outer diameter of the pipe 3. Since the sleeve 11 needs to be adjusted on the pipe 3, the inner diameter of the sleeve 11 is larger than the outer diameter of the pipe 3, making it easier to insert the pipe 3 into the sleeve 11. The diameter of the boss 12 is equal to the inner diameter of the pipe 3.

[0016] The fixing device 2 includes a connecting ring 21, which is threadedly connected to the outer side of the sleeve 11. An annular groove 24 is provided at the upper end of the connecting ring 21, and a sliding block slidably engaged therewith is disposed within the annular groove 24. An arc block 22 is fixedly connected to the upper end of the sliding block. An arc groove 23 is provided at the upper end of the arc block 22. An L-shaped connecting rod 25 is fixedly connected to the lower end of the connecting ring 21. A pad 26 is fixedly connected to the upper end of the horizontal end of the connecting rod 25. Movement of the connecting ring 21 drives the pad 26 and the arc block 22 to move, thereby clamping the corresponding pipe 3, increasing friction and reducing shaking.

[0017] There are four protruding columns 12 , and the angle between adjacent protruding columns 12 is 120°.

[0018] The pad 26 is triangular in shape, and the inclined surface of the pad 26 is arranged on a side away from the pipe 3 .

[0019] The inclined surface of the pad 26 and the side close to the pipe 3 are both provided with anti-skid measures. The anti-skid measures can be provided with anti-skid pads on the inclined surface of the pad 26 and the side close to the pipe 3, or anti-skid grooves on the inclined surface of the pad 26 and the side close to the pipe 3.

[0020] There are at least six connecting rods 25 and cushion blocks 26. A plurality of connecting rods 25 can be placed against the outer circumferential surface of the pipe fitting 3 to avoid positional deviation during installation.

[0021] There are two fixing devices 2 , which are located above and below the boss 12 respectively.

[0022] The diameter of the arc groove 23 is the same as the outer diameter of the pipe 3, so that the contact area between the arc groove 23 and the outer circumferential surface of the pipe 3 is larger.

[0023] The working principle of the present invention is as follows: when using the device, first, the connecting rings 21 on the two fixing devices 2 are connected to the sleeves 11 respectively through threads, and the sleeves 11 are put on the vertical pipe fittings 3 for installing the scaffold, and then the sleeves 11 are adjusted to the appropriate position of the vertical pipe fittings 3, and the horizontally arranged pipe fittings 3 are put on the bosses 12 at the corresponding positions, and then the connecting rings 21 are rotated to make the two connecting rings 21 move toward each other. During the movement of the connecting rings 21, the corresponding connecting rods 25 are driven to move, and then the pads 26 are driven to move into the sleeves 11. The pads 26 are triangular. As the pads 26 move, the gap between the sleeves 11 and the pipe fittings 3 is filled by the pads 26, and the friction between the pads 26 and the sleeves 11 and the pipe fittings 3 gradually increases, thereby limiting the movement of the vertical pipe fittings 3 relative to the sleeves 11.

[0024] During the movement of the connecting ring 21, the arc block 22 is also driven to move, so that the arc block 22 gradually approaches the transversely arranged pipe fitting 3. When the connecting ring 21 drives the pad 26 to move to the appropriate position, the inner wall of the arc groove 23 on the arc block 22 also abuts against the outer circumferential surface of the transversely arranged pipe fitting 3, thereby increasing the friction between the transversely arranged pipe fitting 3 and the inner wall of the arc groove 23, clamping the transversely arranged pipe fitting 3 and reducing its relative shaking.

[0025] The novel method connects the horizontal and vertical pipes 3 by means of a fixing device, without the need for bolts, and the individual fixing devices 2 are larger than bolts, thereby reducing the risk of loss and saving maintenance costs.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other configurations without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations coming within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference signs in the claims should not be construed as limiting the claim to which they relate.

[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
