Detailed Description

The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Compare in circular steel pipe, the I-steel structure is special, and the clamping is fixed more difficult, has designed this I-steel 800's high-efficient connector link in order to solve this problem. Fig. 1-3 illustrate a high efficiency connector buckle for i-beams, comprising: a connecting piece 100, two fasteners 200, a clamping piece 300 and a connecting screw rod 400. The connecting member 100 has two oblong holes 110 at both ends, the two oblong holes 110 extend in the same line, and the connecting member 100 has a first threaded hole 120 in the middle. The two fasteners 200 are connected to the two oblong holes 110 by bolts, one end of each fastener 200 has a pressing plate 210 protruding toward the connecting member 100, and the two pressing plates 210 are disposed opposite to each other and can press the inner side of the flange of the i-beam 800. The clamping plate 300 is used for fixing external steel, and the clamping plate 300 is provided with a second threaded hole 321. Both ends of the connection screw 400 are connected to the first and second screw holes 120 and 321, respectively.

When the connecting buckle is used, the connecting piece 100 and the I-beam 800 to be connected are vertically placed, the I-beam 800 is placed between the two buckling pieces 200, the buckling pieces 200 are moved towards the middle of the I-beam 800 along the two oblong holes 110 respectively, the two buckling pieces 200 are closed towards the I-beam 800 until the I-beam cannot move further, two bolts on the buckling pieces 200 are screwed, and therefore the pressing plate 210 is pressed on the inner side of a wing plate of the I-beam 800, and the buckling pieces 200 are fixed with the I-beam 800 at the moment. The steel to be connected is then connected to the jaw member 300, thereby achieving the connection of the outer steel with the i-beam 800. The distance between the i-beam 800 and the external steel can be adjusted as required by using the connection screw 400. The connecting buckle is stable in connection, detachable and convenient to use.

In order to improve the structural strength of the connecting member 100, in the present embodiment, the connecting member 100 is a U-shaped steel structure, the connecting member 100 includes a bottom plate 130 and two side plates 140, and the oblong hole 110 and the first threaded hole 120 are opened on the bottom plate 130. U shaped steel structure compares in dull and stereotyped structure, and structural strength obviously promotes. In this scheme, install gasket 700 between the nut of bolt and bottom plate 130, gasket 700 mainly used makes bottom plate 130 atress more even.

In order to facilitate the operation of the connection buckle, the two side plates 140 at the two ends of the connection piece 100 are provided with inclined surfaces 141, the inclined surfaces 141 extend in a direction approaching the bottom plate 130 toward the middle of the connection piece 100, and the buckle 200 presses on the inclined surfaces 141. Compared with the design without the inclined plane 141, after the inclined plane 141 is designed, only two bolts on the connecting piece 100 need to be continuously screwed, and the two connecting pieces 100 automatically approach to the middle i-shaped steel 800 along the inclined plane 141 until the fastening is completed.

In order to prevent the two fasteners 200 from rotating in the process of moving towards the middle, so that the pressing plate 210 and the wing plate of the i-beam 800 are offset, in the present embodiment, the side of the fastener 200 opposite to the pressing plate 210 is provided with a guide plate 220, both ends of the guide plate 220 are provided with steps 221, and the steps 221 are disposed on the two inclined surfaces 141. The two steps 221 have a limiting function, so that the fastener 200 can only move along the groove extending direction of the U-shaped steel.

In order to improve the structural strength of the latch 200, the other two sides of the latch 200 have a connection plate 230 connecting the guide plate 220 and the pressing plate 210. The connecting plate 230, the pressing plate 210 and the guide plate 220 enclose the periphery of the latch 200, thereby enhancing the bending resistance of the latch 200.

In order to reduce the friction between the fastener 200 and the inclined surface 141, so that the fastener 200 can smoothly move along the inclined surface 141 during the process of tightening the bolt, the surface of the step 221 contacting the inclined surface 141 is an arc-shaped surface (not shown).

In addition, the efficient connector link for the h-beam further comprises a first round nut 500, two ends of the connecting screw 400 are provided with clamp springs 410, and the first round nut 500 is located at the outer side of the connecting piece 100 and pressed on the bottom plate 130. The first round nut 500 can fix the positional relationship of the connector 100 and the connection screw 400.

The outer peripheral surface of the connecting screw 400 is provided with a limiting plane 420, the first circular nut 500 is provided with two limiting holes 510, cotter pins 520 are inserted into the two limiting holes 510, and the cotter pins 520 are matched with the limiting plane 420. The cotter pin 520 is matched with the limit plane 420 to prevent the first round nut 500 from rotating accidentally, thereby preventing the nut from loosening.

In this scheme, splint spare 300 includes first splint 310 and second splint 320, and the centre of first splint 310 has dodges the hole 311, and second screw hole 321 is located the centre of second splint 320 for the high-efficient connector link of I-steel still includes the circular nut of second 600, and the circular nut of second 600 passes dodges the hole 311 and presses in second splint 320, and the both ends of first splint 310 and second splint 320 are connected through the screw. The external steel material targeted in this embodiment is a plate-shaped steel material, and therefore, the plate-shaped steel material can be fixed well by sandwiching the plate-shaped steel material between the two clamping plates. When it is required to connect two i-beams 800, the clamping plate 300 can be replaced by the connecting member 100 and two clasps 200.

In order to facilitate the rotation of the first and second

circular nuts

500 and 600 using a tool, the first and second

circular nuts

500 and 600 each have a clamping plane 610 on the outer peripheral surface thereof.
