Fixing tool method for installing embedded bolt set

Abstract

The invention discloses a tool fixing method for installing an embedded bolt set, and relates to the technical field of embedded bolt fixing, and the method comprises the following steps: 1, processing a steel plate in a prefabrication workshop, and performing high-precision trepanning according to the position of the embedded bolt set, with the deviation of the trepanning position being-0.5 to + 0.5 mm; secondly, the first angle steel, the second angle steel and the reinforcing steel bars are pre-buried and fixed; thirdly, the steel plate with the bolt holes is placed on the first angle steel; and fourthly, before concrete pouring, bolts penetrate through the upper and lower steel plates, and nuts are used for fixing after the exposed length is adjusted. According to the fixing tool designed by the invention, the relative positions of the bolts of the bolt group are ensured through the high-precision perforated steel plate, so that the steel plate only needs to be measured and positioned once in the construction process, the field installation and measurement work is reduced, personal errors are avoided, the positioning precision is ensured, and the construction is more facilitated.

Description

technical field [0001] The invention relates to the technical field of pre-embedded bolt fixing, in particular to a fixing tooling method for installing a pre-embedded bolt group. Background technique [0002] Pre-embedded bolt construction is a key construction activity in concrete construction projects. As the rooting point of subsequent equipment, supports, etc., its installation accuracy determines whether subsequent installation activities can be carried out as required; [0003] Pre-embedded bolts need to be fixed and fine-tuned in advance before concrete pouring. When a group of pre-embedded bolts is constructed, in addition to the position of a single bolt, it is also necessary to ensure the relative position of the pre-embedded bolts in the group, which are generally fixed and positioned. The method is: use a steel frame to form a tooling skeleton to fix the embedded bolts, and the tooling skeleton can realize the rough positioning of the embedded bolts. By adding a...
