A modular fastening connection as claimed in claim 1, wherein: the connecting assembly is characterized in that an adjusting groove (401) is formed in one end, connected with the rotating pin (5), of the connecting assembly (4), an H-shaped notch (402) is formed in one end, connected with the transverse steel beam, of the connecting assembly, and threaded holes are formed in the upper end face and the lower end face of the opening of the H-shaped notch (402).
6. A rapid assembling method of an H-shaped steel girder structure connecting node, for rapid assembling and fixing the H-shaped steel girder structure connecting node and adjusting an angle value α between a transverse steel girder and a longitudinal steel girder by using the combined fastening connector of claims 1 to 5, comprising the steps of:
determining a design elevation at a connecting node of an H-shaped steel beam structure, determining the installation position of a clamping assembly (1) of the combined fastening connecting piece according to a size value of the design elevation, and paying off the installation position;
secondly, according to paying-off positions, one clamping assembly (1) is placed at a groove on any side of the longitudinal steel beam, a limit bolt (201) is sequentially rotated according to the cross sequence of first up and then down, and the end part of the limit bolt (201) extrudes a wedge-shaped clamping block (202), so that the wedge-shaped clamping block (202) extends outwards out of a wedge-shaped groove (102) of the clamping assembly (1) to reliably contact with the outer wall of the longitudinal steel beam through a damping lug (203);
step three, installing the clamping assembly (1) on the other side to a paying-off position according to the method in the step two;
step four, connecting one end of a connecting component (4) with a clamping component (1) by using a fixing pin (6), adjusting the position of the connecting component (4) until the upper end surface of the connecting component is vertical to a longitudinal steel beam, rotating a driving rod (302) by a handle (303), and inserting a rotating pin (5) to connect the sliding component (301) with the connecting component (4) when the sliding component (301) moves in a cavity inside the clamping component (1) along the longitudinal steel beam stretching direction until the central axis of the mounting position of the rotating pin (5) is coincident with the central line of an adjusting groove (401) under the driving of the driving rod (302);
fifthly, continuing to rotate the handle (303) to enable the sliding piece (301) to move in the cavity inside the clamping assembly (1) along the extension direction of the longitudinal steel beam until the value of the included angle between the upper end surface of the connecting assembly (4) and the outer vertical surface of the longitudinal steel beam is equal to the designed value alpha of the angle between the transverse steel beam and the longitudinal steel beam;
step six, the transverse steel beams on two sides are sequentially inserted into the H-shaped notch (402) of the corresponding connecting assembly (4), the fixing mode between the transverse steel beams and the connecting assembly (4) is selected according to the design load of the transverse steel beams, and the transverse steel beams are fixed, so that the assembly of the connecting nodes of the H-shaped steel beam structure is completed.
