Integrated type double-self-locking intelligent informatization steel support and loading and detaching method thereof

Abstract

The invention discloses an integrated type double-self-locking intelligent informatization steel support and a loading and detaching method thereof. An oil cylinder is arranged in a first end of a cylinder body, an oil pressure sensor, a displacement sensor and a hydraulic lock are arranged on the oil cylinder, an opening is formed in a second end of the cylinder body, a middle main stress plate is axially arranged in the opening, the two sides of the middle main stress plate and the inner wall of the cylindrical opening are integrally welded, first ends of supporting rods at an adjustable end are connected with connecting plates respectively, the connecting plates are connected with the oil cylinder, second ends of the supporting rods clamp force bearing plates respectively, supporting sliding shoes are connected with the force bearing plates through bolts, the supporting rods clamp the middle main stress plate respectively, and the force bearing plates are aligned with the middle main stress plate. Along with loading extending of the oil cylinder, the supporting sliding shoes extend to the outer portion of the cylinder body in the extending direction of the middle main stress plate, a steel wedge is detachably inserted and supported between the middle main stress plate and the force bearing plates, and along with unloading retracting of the oil cylinder, the supporting sliding shoes retracts to the cylinder body in the extending direction of the middle main stress plate.

Description

technical field [0001] The invention relates to the construction field, in particular to an integrated double self-locking intelligent information steel support and its loading and dismounting method. Background technique [0002] Steel supports are generally inclined connecting members, the most common ones are herringbone and cross shapes, and the cross-sectional forms can be steel pipes, H-shaped steel, angle steel, etc., and their function is to enhance the stability of the structure. When it comes to braces, it generally refers to the round steel that binds the purlins. To put it bluntly, it is a thick steel bar, which is also to enhance the stability of the purlins, so that the purlins are not easy to be unstable and damaged under certain external forces. The cross-sectional form of the purlin generally has H-shaped steel, C-shaped, Z-shaped, etc., and its function is to reduce the span of the roof panel and fix the roof panel.

Problems solved by technology

However, in practical applications, this kind of steel support also exposes its insurmountable shortcomings: during the installation process of the support, the prestressing process requires the cooperation of a crane and two loading jacks, and there is no data collection record for the pressurization value. The value depends on the experience and responsibility control of the operator, and there are many construction techniques and a long time; in addition, during the demolition process, due to the long-term stress and deformation of the steel wedge, it is difficult to dismantle, or even impossible to dismantle. Due to the excavation and deformation of the foundation pit, the axial force attenuation of some supports will o
