Embodiment 1

[0027] see now figure 2 with figure 2 , figure 2 for figure 1 The sectional view of A-A in, image 3 for figure 1 Sectional view of B-B in middle.

[0028] The fine-tuning method of the pre-embedded large overweight bolt sleeve group fixing frame of the present invention, the bolt sleeve group fixing frame includes a fixed bracket and a movable fixed frame, the fixing bracket is a box-shaped double-barrel structure, and four vertical poles are provided, and the vertical poles are channel steel 1. The channel steel is provided with a number of bolt holes 3 from bottom to top, so that the screw rod or fixing steel bar can penetrate through the holes when fixing later. The fine-tuning method of the pre-embedded large super-heavy bolt sleeve group fixing frame of the present invention comprises the following steps:

Abstract

The invention discloses a method for finely adjusting a fixing frame of a pre-buried large overweight bolt sleeve group. The method is characterized by comprising the following steps of: a, manufacturing a movable fixing frame matched with a fixing bracket according to the fixing bracket on the basis of burying the original fixing frame; b, positioning according to design, and arranging a movablebracket on transverse angle steel added at the bottom of the fixing frame; c, after binding reinforcing steel bars, finally stretching and moving an adjustable support and a sleeve body through a chain block; and d, after the positioning requirement of design precision is met, inserting a bolt or a long reinforcing steel bar of a corresponding specification into an adjusted bolt hole for fixing, so that the sleeve group is fixed with the fixing frame. The method for finely adjusting the fixing frame of the pre-buried large overweight bolt sleeve group has the advantages that: the added movablebracket has a simple structure and is convenient to manufacture; and a movable base of the sleeve is added by using the movable bracket on the basis of burying the original fixing frame, so that thefine adjustment function of the sleeve is convenient to implement, the sleeve can be well positioned accurately, the fine adjustment operation environment is good, time and labor are saved, and the engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for fine-tuning a fixed frame of a pre-embedded bolt sleeve, in particular to a method for fine-tuning a fixed frame of a pre-embedded large overweight bolt sleeve group. Background technique [0002] In the construction of industrial plants, mine development and other projects, the concrete pouring process often encounters the technical problems of precise fixing in advance and pre-embedding large bolt sleeve groups (single sleeve weight is more than 100 kg). For such engineering projects, the design diameter of the reinforcement itself is relatively large and the spacing is relatively dense. The bolts are used to fix the equipment installation in the later stage and bear the dynamic load of the equipment. . [0003] The common pre-embedded fixing bolt sleeve method adopts profiles such as angle steel and channel steel, and designs and sets up the sleeve pre-embedded fixing frame according to the weight of the sleeve...
