Embodiment Construction

[0017] like figure 1 As shown, the fastener for the I-shaped steel roof of the present invention includes a first buckle 1 and a second buckle 2 that is compatible with the first buckle 1 . The first buckle 1 and the second buckle 2 are left-right symmetrical. Wherein, the first buckle 1 is substantially in a "T" shape, including a first straight side 31 and a first transverse side 41 connected to the middle of the first straight side 31 .

[0018] A first straight groove 32 extending on the first straight edge 31 is formed on the first straight edge 31 , and a first transverse groove 42 extending on the first lateral edge 41 is formed in the middle of the first lateral edge 41 . The left end of the first transverse groove 42 communicates with the first straight groove 32 and forms an included angle of 75 degrees, and the included angle can range from 72 degrees to 77 degrees. Wherein, the right end of the first transverse groove 42 is inclined upward. The first straight gr...

Abstract

The invention relates to a buckling member for an I-steel tent, which comprises a first buckling sheet and a second buckling sheet adaptive to the first buckling sheet. The first buckling sheet and the second buckling sheet are respectively provided with clamping grooves. The clamping groove on the first buckling sheet corresponds with the clamping groove on the second buckling sheet. The first buckling sheet and the second buckling sheet are respectively provided with screw holes. When the buckling member for the I-steel tent disclosed by the invention is used, I-steel as a tent leg and I-steel as a transverse beam are tightly clamped and fixed together through the first buckling sheet and the second buckling sheet; the two I-steels are firmly connected and fixed in the clamping grooves on the buckling sheets respectively; compared with the prior art, the connection through the buckling member is more firm; higher-intensity impact or vibration can be born; in the event of tunnelling and preventing gun, the I-steel tent cannot be collapsed and dismounted; and the buckling member for the I-steel tent disclosed by the invention is simple in structure and applied to large-range popularization.

Description

technical field [0001] The invention relates to a construction auxiliary device, in particular to a fastener for an I-shaped steel shed. Background technique [0002] It is very common to use I-beam shed support underground in mines, especially during the excavation process. The specific method is to use I-beams as beams and legs to build a scaffold, arrange multiple scaffolds according to certain rules, and support the excavation roadway, so as to protect the excavation face. [0003] The outriggers and beams of the traditional I-beam shed are connected and reinforced by braces. This connection is not strong enough to withstand high-intensity shocks or vibrations. Easy to collapse and disintegrate. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a fastener for an I-shaped steel shed that can securely connect the legs and the beam. [0005] The fastener for the I-shaped steel shed of the present invention incl...
