Steel structural concrete-based pre-cast bolt positioning device

Abstract

The invention discloses a steel structural concrete-based pre-cast bolt positioning device. The device consists of an upper template, a lower template and a bolt sleeve, wherein the upper template and the lower template are rectangular, and the lengths of corresponding edges of the upper template and the lower template are equal to each other; the upper side and the lower side of the bolt sleeve are welded to the upper template and the lower template respectively; the inner diameter of the bolt sleeve is 5 millimeters larger than the diameter of a pre-cast bolt; bolt holes are formed at the connecting positions between the upper template and the bolt sleeve as well as the lower template and the bolt sleeve; the diameter of each bolt hole is 1 millimeter larger than that of the pre-cast bolt; and a feeding hole is correspondingly formed in the middle of the upper template and the lower template. In the steel structural concrete-based pre-cast bolt positioning device, the upper template, the lower template and the bolt sleeve are utilized, the pre-cast bolt is fixed on the positioning device in advance through the positioning between the upper template and a concrete-based steel mold, and the steel structural concrete-based pre-cast bolt positioning device is detached after concrete casting is finished, so that the accurate positioning of the pre-cast bolt in an independent foundation can be greatly improved, and geometric tolerance can be controlled to be + / -2mm.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to concrete pouring auxiliary equipment, in particular to a steel structure concrete foundation embedded bolt positioning device. Background technique: [0002] In the prior art, in the installation of steel columns in common steel structure buildings, the precise positioning of embedded bolts is a construction problem that has plagued the installation quality and progress of steel columns for a long time. During the process of pouring and mixing the embedded bolts, there are many reasons that will cause the embedded bolts to deviate from the installation position, such as: pouring of concrete, insertion of vibrating rods, deformation (collision) of fixing bolts, and deformation of concrete formwork. Displacement, etc. will affect the displacement of the embedded bolts in the independent concrete foundation, and it is difficult to detect when the concrete is poured, and if it is found out ...
