Abstract

The invention provides a connection device with adjustable length, which includes two sets of clamps and an adjusting device, the adjusting device is arranged on the opposite inner side of the two sets of clamps, and the clamps include a clamping plate, an adjusting bolt and a fixing plate. The adjusting bolt is placed on the outer panel of the clamping plate, and the fixing plate is arranged on the top of the adjusting bolt. The side is provided with an accommodating hole, and a spring is arranged in the accommodating hole, and the spring is connected to the telescopic mandrel, and the extension direction of the opposite side of the fixed rod is provided with a structural hole cooperating with the telescopic mandrel. The invention has the beneficial effects of simple structure and convenient operation, which not only saves cost, but also has relatively high connection strength.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, in particular to a connection device with adjustable length. Background technique [0002] At present, the widely used concrete cast-in-place formwork support system is constructed by using wooden squares as keels and steel pipes as supports. The use of this wooden keel structure requires a large workload, time-consuming and laborious, and low construction efficiency. At the same time, iron wires, iron nails and other auxiliary materials are seriously wasted, and the wooden keel basically cannot be reused. In recent years, a formwork support composite structure has appeared, which replaces the wooden square with a steel keel. It is composed of a plurality of square tubular main keels and sub keels arranged in parallel in the longitudinal and transverse directions on the same plane, and is formed by an angle slot plate placed on the side of the main keel. With this steel ...
