Description

Technical Field

[0001] The invention relates to the field of steel structure connectors, and in particular to an H-shaped steel beam locking structure and a locking method thereof. Background Art

[0002] H-shaped steel is widely used in constructing steel structure buildings due to its strong stress-bearing effect, and H-shaped steel is mainly used for main beams or supporting beams. The H-shaped steel has two parallel flange plates and a web plate vertically connecting the two flange plates, so that its cross-section is H-shaped.

[0003] In steel structures with larger spans, H-shaped steel beams need to be butt-jointed and fixed. Traditionally, multiple steel plates are placed flat against the flanges and webs of the steel beams, and then several screws are passed through the flanges and webs to fix the connected steel plates. This method requires more screws to be assembled on site on each surface of the H-shaped steel connection, which takes a long time to butt joint. In addition, more nail holes are opened on the surface of the flanges and webs, which causes certain damage to the structure of the H-shaped steel and reduces its strength. Summary of the invention

[0004] In order to make up for the deficiencies of the existing technical problems, the purpose of the present invention is to provide an H-shaped steel beam locking structure and a locking method thereof, which are used to solve the problem that traditional H-shaped steel beam docking requires bolts at each connection, resulting in a long construction time and the structural strength of the steel beam is destroyed.

[0011] Preferably, a U-shaped pasting plate is provided on the inner side of the gusset plate, and two groups of sliding columns are fixed to the inner wall of the gusset plate. The sliding columns are slidably plugged into the pasting plate, and the screw rod passes through the pasting plate. The contact cylinder and the contact rod contact the pasting plate, so that the pasting plate is flush with the docking position of the H-shaped steel web.

[0012] Preferably, the right-angled bends of the two gusset plates have L-shaped hook plates in opposite directions, and the hook plates are interlocked to lock the two gusset plates to clamp the H-shaped steel.

[0013] Preferably, the inner side edge of the hook plate is a beveled edge, so that the width of the end of the hook plate gradually increases in the direction of connecting to the buckle plate.

[0030] The technical solutions in the embodiments 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 present invention, rather than all the embodiments.

[0031] like Figure 1 , Figure 2 As shown, the H-shaped steel beam locking structure has two gusset plates 1, both sides of the gusset plates 1 are bent 90° to form a right-angled bend, and the edge of the right-angled bend is integrally fixed with an L-shaped hook plate 11, and the end faces of the H-shaped steel beam are butted, and the two gusset plates 1 are symmetrically arranged on the left and right sides of the H-shaped steel beam, and the hook plates 11 connected to the two gusset plates 1 are in opposite directions, and the two gusset plates 1 are staggered and buckled on both sides of the H-shaped steel beam respectively, and the right-angled bend is flat against the outer surface of the flange plate, and then the two gusset plates 1 are moved toward the butt joint of the H-shaped steel beam, so that the L-shaped hook plates 11 on the edges of the two gusset plates 1 are buckled with each other, so that the two gusset plates 1 are locked and tightly embraced in the left and right directions, and the butt locking of the H-shaped steel beam is pre-fixed, which is convenient for construction personnel to free their hands for subsequent locking work.

[0032] like Figure 2As shown, the inner side of the hook plate 11 is a beveled side, so that the width of the end of the hook plate 11 gradually increases in the direction of connecting to the buckle plate 1, making it easier for the hook plates 11 to buckle and gradually tighten with each other.

[0033] like Figure 4 , Figure 5 As shown, a cross rod is arranged on the inner side of the two gusset plates 1, and the cross rod is composed of two cross-distributed support rods 2. A rotating shaft passes through the intersection of the support rods 2 and is rotatably connected to the gusset plates 1, and the rotation point is located at the center of the inner surface of the gusset plates 1. The ends of the support rods 2 are rotated to install nuts 21, and two fastening screws 6 are symmetrically arranged on the outer side of each right-angle bend. The two fastening screws 6 are respectively aligned with the flange plates of the two butted H-shaped steel beams, and the fastening screws 6 are passed through the right-angle bend, the flange plates and the nuts 21 are threadedly connected. By tightening the fastening screws 6, the nuts 21 are tightly attached to the inner surface of the flange plates, and the four supporting ends of the two support rods 2 support the flange plates of the butted H-shaped steel beams, thereby realizing the upper and lower, front and back connection and locking of the two H-shaped steel beams.

[0034] like Figure 6 As shown, the locking of the two buckle plates 1 in the left and right directions is achieved by four tension screws in addition to the snap-fitting hook plates 11. The tension screws include a feeler cylinder 5 and a feeler rod 51 of the same diameter. The ends of the feeler cylinder 5 and the feeler rod 51 have hexagonal stops. The feeler cylinder 5 and the feeler rod 51 are penetrated from the outside to the inside of the buckle plates 1 on both sides and then aligned. The ends of the feeler rod 51 are fixed with a screw rod 52 of reduced diameter. The screw rod 52 penetrates the web and is threadedly connected to the feeler cylinder 5, so that the two buckle plates 1 are locked in the left and right directions, and at the same time, the locking strength of the buckle plates 1 and the H-shaped steel beam in the front and rear directions is increased.

[0035] like Figure 4 As shown, two positioning holes 22 are symmetrically provided on the surface of each support rod 2. When the screw 6 is threadedly locked into the nut 21, the crossing angle of the two support rods 2 is fixed. At this time, the four positioning holes 22 are aligned with the four tension screws. When the tension screws are installed, the feeler tube 5 and the feeler rod 51 are adapted to be inserted into the aligned positioning holes 22, thereby increasing the locking strength of the crossing angle of the support rod 2, so that the crossing rod can provide stable supporting strength for the butted H-shaped steel beam.

[0036] like Figure 4 , Figure 5 , Figure 6As shown, a U-shaped pasting plate 3 is provided on the inner side of the buckle plate 1, and two groups of sliding columns 4 are fixed on the inner wall of the buckle plate 1. The sliding columns 4 are slidably plugged with the pasting plate 3, so that the buckle plate 1 can move left and right. The surface of the buckle plate 1 has four through holes for positioning and tensioning screws. The diameter of the through holes is larger than the diameter of the screw rod 52 and smaller than the diameter of the contact tube 5 and the contact rod 51. When the two buckle plates 1 are locked with the tensioning screws, the screw rod 52 passes through the through holes on the surface of the pasting plate 3 and is connected with the contact tube 5. The ends of the contact tube 5 and the contact rod 51 are against the pasting plate 3, so that the pasting plate 3 is against the docking position of the web plate, and the upper and lower surfaces of the pasting plate 3 are flat against the docking position of the flange plate, thereby realizing the docking reinforcement of the inner side of the H-shaped steel beam.

[0037] like Figure 3 , Figure 4 As shown, the inner side of the right-angle bending part of the buckle plate 1 is provided with a buckle groove 12. When the buckle plate 1 is clamped on both sides of the H-shaped steel beam, the buckle groove 12 is adapted to be clamped on the edge of the H-shaped steel flange plate, which is used to increase the anti-deformation strength between the parallel flange plates, thereby improving the overall locking strength of the H-shaped steel beam alignment part.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
