Problems solved by technology

[0005] However, in the actual construction process, there are manufacturing errors in the dimensions of the various components of the connecting device, the on-site operating environment is complex, and the technical level of the construction personnel is uneven. It is often impossible to align the bolts and nuts, resulting in the inability to fasten some bolts and nuts
In this case, the stress on each joint in the connecting device (that is, the joint between the bolt and the nut) is uneven; the bolts at the joint with a greater force may deform, fall off, or break and other abnormal phenomena, resulting in the The initial support of the device cannot effectively withstand the pressure of the surrounding rock or soil, which poses a threat to the construction safety of the underground project
[0006] To sum up, the existing connecting device has the problem that the actual bearing capacity of the primary support including the connecting device is insufficient

Abstract

The invention discloses a rotary fastener type connecting device comprising a pair of rotary fastening plates. At least two L-shaped upper rotary fasteners are arranged on a lower plate surface of an upper rotary fastening plate in the pair of rotary fastening plates; each L-shaped upper rotary fastener comprises a first portion perpendicular to the lower plate surface of the upper rotary fastening plate and a second portion parallel to the lower plate surface of the upper rotary fastening plate; at least two lower rotary fasteners are arranged on an upper plate surface of a lower rotary fastening plate in the pair of rotary fastening plates; the lower rotary fasteners face the clearance between the upper rotary fasteners; the upper rotary fastening plate is rotationally connected with the rotary fastening plate, and each lower rotary fastener is clamped between the second portion of each L-shaped upper rotary fastener and the lower plate surface of the upper rotary fastening plate. In the rotary fastener type connecting device, contact areas between the upper rotary fasteners and the lower rotary fasteners are large and equal; therefore, the upper rotary fasteners or the lower rotary fasteners can be prevented from deforming, falling off or breaking and the like, and further the rotary fastener type connecting device has enough bearing capacity in preliminary bracing.

Description

technical field [0001] The invention relates to the field of civil engineering construction, in particular to a turn-buckle connection device. Background technique [0002] With the development of my country's economy and society, urban rail transit, railways, highways, municipal facilities and other infrastructures have been extensively built. At present, various underground works such as underground excavation and tunnels in the above-mentioned projects are often constructed by "shallow buried underground excavation method". [0003] During the construction process of the "shallow burial and underground excavation method", the construction of primary support is required. Primary support usually consists of a steel grid arch and shotcrete on its foundation. Wherein, the steel bar grid arch frame is assembled by a plurality of steel bar grid sections through connecting devices. [0004] In order to quickly construct the initial support, the existing connection device usua...
