[0026] On the outer side of the end face edge of the support frame 130 away from the pressing plate 110, a support ring 150 is provided, and a plurality of first reinforcing ribs 160 are fixedly arranged between the support ring 150 and the pressing plate 110; the operation stress area of the clamp is increased through the support ring, which is convenient for cooperating with external tools; the structural strength of this part can also be enhanced, and the overall structure is enhanced through the first reinforcing ribs to prevent damage due to stress and extend the service life.

[0027] Further, the support frame 130 includes a U-shaped support frame 131, and the support frame 131 is fixedly connected to the wall surface of the pressing plate 110 away from the clamping groove; the axis of the bending part of the support frame 131 coincides with the axis of the perforation 140; sufficient space is provided for the layout of the perforation, which is convenient for the penetration cooperation of external steel bars and also convenient for the installation of other structural components;

[0028] The support ring is arranged at the edge of one end of the support frame away from the pressing plate, and a plurality of first reinforcing ribs 160 are fixedly arranged on the outer wall of the bending part of the support frame 131; when the butterfly buckle is tightly installed, an external tool needs to be used to clamp the steel bar and pull it outwards. At this time, the bending part position of the support frame is used as the reverse stress point. The provided support ring can expand the cooperation area range, which is convenient for the operation of external tools and also strengthens the overall structure.

[0029] Furthermore, a second reinforcing rib 170 is fixedly provided in the middle of the outer wall of the bent portion of the support frame 131. The two ends of the second reinforcing rib 170 are respectively connected to the support ring 150 and the pressing plate 110. One end of the wall surface of the second reinforcing rib 170 away from the support ring extends to the end of the pressing plate 110, forming a first inclined surface 171, and the whole is in a triangular structure, which can further increase the structural strength, and can also extend the support range to the end of the pressing plate, facilitating the transmission and dispersion of force, and strengthening the overall fastening effect.

[0030] Furthermore, as Figure 2 shown, a reinforcing ring 132 is fixedly provided on the inner wall of the bent portion of the support frame 131. One end of the reinforcing ring extends to the pressing plate, and the other end is flush with the wall surface of the support ring; a notch 133 is provided on one side of the reinforcing ring 132 close to the opening of the support frame 131; this structural design can further strengthen the overall structural strength on the one hand, and on the other hand, it can be used as an extended part of the perforation, facilitating the threading and laying of steel bars, defining the mating part with the steel bars, and facilitating the mating connection between the butterfly buckle and the steel bars.

[0031] Furthermore, a second inclined surface 134 is provided at the end of the support frame 131 away from the second reinforcing rib 170. The second inclined surface extends to the end of the pressing plate away from the second reinforcing rib, and the whole is in a triangular structure, which can further increase the structural strength, and can also extend the support range to the end of the pressing plate, facilitating the transmission and dispersion of force, and strengthening the overall fastening effect.

[0032] Furthermore, as Figure 3 shown, the two ends of the pressing plate 110 are bent away from the support frame; two support plates 180 are fixedly provided on both sides of the wall surface of the pressing plate 110 away from the support frame. The two ends of the support plate 180 are provided with arc-shaped surfaces 181, and an arc-shaped clamping groove 120 is formed with the end of the pressing plate; the provided support plates can further strengthen the overall structural strength, and the clamping groove formed by the arc-shaped surfaces at the ends thereof and the bent ends of the pressing plate is arc-shaped, which can be better clamped on the outside of the pipe strip during construction, facilitating assembly and use.

[0033] Furthermore, a plurality of anti-slip grooves 190 are provided on both the arc-shaped surface 181 and the bent inner wall of the pressing plate 110, which can further increase the cooperation with the external pipe strip and strengthen the fastening effect.

[0034] Furthermore, a support block 182 is fixedly provided between the two support plates 180, and the support block 182 is fixedly connected to the pressing plate 110;

[0035] The perforation 140 penetrates through the center of the support block 182 to connect the two support plates, further strengthening the overall structural strength and preventing the support plates from being deformed and damaged due to force.

[0036] Furthermore, the perforation gradually expands from the end close to the pressing plate towards the direction away from the support frame, forming a flared opening at the port position, which is convenient for threading and matching with external steel bars and facilitates construction operations.

[0037] Furthermore, the fixture is an integrally formed cast iron structure, which is convenient for processing and production, and also ensures that it has sufficient structural strength, prevents easy damage, and extends the service life.

[0038] The present utility model also discloses a butterfly buckle for building construction, as Figure 4 shown, including a locking member 200, a torsion spring 300 and the fixture 100; circular holes 135 are provided on opposite side walls of the support frame 131 for passing and installing a support shaft 400. The support shaft is parallel to the card slot and is located on the side of the perforation away from the second reinforcing rib. The locking member and the torsion spring are installed on the support shaft. The torsion spring provides a locking force for the locking member, so that the teeth of the locking member abut against the steel bar to achieve an effective locking effect. It should be noted that the support shaft, the torsion spring and the toothed locking member are all common fittings in the field of steel bar butterfly buckles, and the cooperation with the fixture is also a conventional cooperation. The specific structure, connection method and usage method will not be elaborated.
