Problems solved by technology

At present, there are few engineering structure laboratories with pedestals in the country, and there is no special tool for adjusting the flatness of the loading hole of the pedestal. Basically, inefficient tools such as square steel pipes, wooden sticks, or jacks are used, which are laborious and labor-intensive and the effect is relatively poor.

Abstract

The invention provides a pedestal loading hole lifting tool which comprises a main screw, a cross rod, a first hook mechanism, a second hook mechanism and a supporting mechanism. The cross rod is provided with an embedded nut, the main screw is connected to the embedded nut in a threaded mode, the two ends of the cross rod are connected to one end of the first hook mechanism and one end of the second hook mechanism respectively, the lower end of the main screw is connected to the supporting mechanism, and the supporting mechanism is used for pushing and supporting a loading hole bottom template. The pedestal loading hole lifting tool has the advantages of being high in efficiency, low in cost and easy and convenient to manually operate.

Description

technical field [0001] The invention relates to a lifting tool for a loading hole of a pedestal. Background technique [0002] The reinforced concrete pedestal is an important facility for pseudo-static or pseudo-dynamic tests of various structural materials, structural components and structural systems in the engineering structure laboratory. The flatness of the hole is the key link to ensure the quality of construction. At present, there are few engineering structure laboratories with pedestals in the country, and there is no special tool for adjusting the flatness of the loading hole of the pedestal. Basically, inefficient tools such as square steel pipes, wooden sticks, or jacks are used, which is laborious and labor-intensive and the effect is relatively poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lifting tool for the loading hole of the pedestal, which has the advantages of high efficiency, low...
