Specific Embodiments

[0019] The following are specific embodiments of the present invention in combination with the drawings, and the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0020] Embodiment

[0021] As Figures 1-3 shown, an adjustable fastener for steel structures includes a clamping plate A 1 and a clamping plate B 2. A connecting part 3 is provided between the clamping plate A 1 and the clamping plate B 2. A pressing plate 4 is provided at one end of the clamping plate A 1. There is a certain gap between the clamping plate A 1 and the clamping plate B 2. A clamping plate A 5 is provided at the end of the pressing plate 4 far from the clamping plate A 1. A clamping plate B 6 is provided at the extending end of the clamping plate B 2 far from the connecting part 3. Locking grooves 7 are formed on both the clamping plate A 1 and the clamping plate B 2, and the two locking grooves 7 are arranged corresponding to each other.

[0022] The connecting part 3 is arc-shaped. A channel 8 is provided on the connecting part 3, and the connecting part 3, the clamping plate A1, and the clamping plate B2 are of an integrally formed structure. The clamping plate A1 and the clamping plate B2 form a connecting structure at a certain angle through the arc-shaped connecting part 3. When in use, the fastener can make the clamping plate A1 and the clamping plate B2 have a certain bending strength through the connecting part 3. After the clamping plate A1 and the clamping plate B2 are subjected to pressure, they can produce a certain amount of stretching and compression deformation.

[0023] The clamping plates A5 and B6 have the same structure. There are included angles 9 between the clamping plates A5 and B6 and the pressing plate 4 and the clamping plate B2 respectively, and the angle of the included angle 9 is less than 90 degrees. The clamping plates A5 and B6 respectively correspond to the two side edges of the steel structure member to achieve the effect of clamping and fixing.

[0024] On the side of the pressing plate 4 away from the clamping plate A1, there are a plurality of circular protrusions 10. A positioning hole 11 is provided among the plurality of circular protrusions 10. The pressing plate 4 is perpendicular to the clamping plate A1. By the pressing plate 4 and the clamping plate B2 respectively clinging to two adjacent sides of the steel structure, a plurality of pressure points are formed between the plurality of circular protrusions 10 and the steel structure to generate a certain frictional force to prevent slipping, and a locking screw is inserted into the positioning hole 11 and the reserved hole on the steel structure to achieve further locking and fixing.

[0025] At both the upper and lower ends of the two locking grooves 7, there are an extrusion groove one 12 and an extrusion groove two 13 respectively. The extrusion groove one 12 and the extrusion groove two 13 are arranged in pairs opposite to each other. A limiting block 14 is also provided in the locking groove 7, and the limiting block 14 extends inwards. The extrusion groove one 12 and the extrusion groove two 13 are respectively formed by extruding from the outside to the inside of the clamping plate A1 and the clamping plate B2, which can limit the deformation amount after the clamping plate A1 and the clamping plate B2 are extruded inwards. During installation, the clamping plate A1 and the clamping plate B2 are locked by inserting a positioning bolt into the locking groove 7. Among them, the positioning bolt can be limited by the limiting block 14 to play a role in preventing loosening.

[0026] When in use, the adjustable fasteners can be used in a pairwise mirror image manner. Two steel structure members are placed closely and side by side. Two fastener bodies are respectively installed on both sides of the two steel structure members. The pressing plate 4 and the clamping plate B2 respectively cling to two adjacent sides of one of the steel structure members. The included angle between the clamping plate A1 and the clamping plate B2 can be adjusted according to the rectangular size of the steel structure member for adaptation, and the clamping plates A5 and B6 are clamped to the edges of the other two sides of the steel structure member. Subsequently, a locking screw is inserted into the positioning hole 11 on the pressing plate 4 and the reserved hole on the steel structure to achieve pre-fixing. Finally, a long-strip fastener connecting fitting and two positioning bolts are used to connect the two mirror-installed fasteners into one body, and horizontal or vertical locking and fixing between the two steel structure members is achieved according to the installation requirements of the steel structure member.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
