Abstract
Installing method of the integral sleeve of a kind of apparatus foundation T -bolt (diameter <= 48mm) includes the following steps--a: embedded software b: Line set of reference bus based on the installation of equipment foundation. c: The sub line is installed based on the center location of the sleeve. d: The support frame of T-bolt sleeve and eT-bolt sleeve is installed , tested and retested. The integral sleeve of installing method of T-bolt whose diameter is <= 48mm has the advantage of being reasonable design of installing steps and convenient to operate. Two sets of fixed supporting systems, which are mutually independent, are installed, wherein, one set is used as line set of reference bus for construction surveying, the other is used for support frame to fix the sleeve. Two sets of supporting systems are used to ensure the installation accuracy and measuring accuracy of the sleeve and the embedded accuracy of the T-bolt sleeve. Also the advantage of two sets fixed supporting systems is that the verticality of the sleeve installation is up to <=L/1000, that is, the levelness of anchoring surface is up to <=1/1000and the center deviation of sleeve is limited to 5mm.
Description
Technical field
The present invention relates to the sleeve installation method in a kind of apparatus foundation bolt Embedment Construction, specifically, it is a kind of integral sleeve installation method of the t type diameter of bolt≤48mm.
Background technology
The foundation bolt of partial metallurgical industrial equipment is detachable, i.e. foundation bolt is not directly to be anchored in base concrete, but it is anchored in t type bolt collar (" t type bolt collar " hereinafter referred to as " sleeve "), sleeve is together constructed with basis, directly it is anchored in basis, until installing equipment, ability by t type bolt insertion sleeve, during equipment replacement, can dismantle in sleeve by t type bolt.
T type bolt top is screw rod, and bottom is t type head, and configure with it is the sleeve with anchor plate, by the anchor force between t type head and anchor plate, to install fastening apparatus.Equipment install after profile as shown in figure 1, the figure of wherein black lines composition is the assembly that t type bolt and integral sleeve are constituted, during construction foundation of civil work, first that sleeve is pre-buried, t type bolt just anchors in sleeve in equipment erection stage.
Basic demand installed by t type bolt collar assembly: only works as t type head and the middle draw-in groove of anchor plate is identical good, the contact of anchoring face is tight, ability uniform force, if t type head and anchor plate are linear contact lay, when even only a little contacting, bolt local pressure, the life-span can be had a strong impact on.Perpendicularity that therefore sleeve is installed is necessary≤l/1000, namely the levelness of anchoring plate face necessary≤1/1000, bushing core deviation controls within 5mm (centre deviation of t type bolt is 2mm).The pre-buried precision therefore improving t type bolt collar is the key that t type bolt integral sleeve is installed.
Chinese patent cn102080417 b disclosed large-scale t type sleeve bolt split burial and construction method on May 23rd, 2012, including: embedded iron parts, installation bolt fixed mount above embedded iron parts are arranged on bed course；After confirming bolt-center control point position, anchor plate is welded on bolt fixed mount；Anchor box in anchor plate bottom welding；Bolt collar is lifted, by bolt collar with anchor plate group to accurately rear firm welding after checking anchor plate and anchoring box position again；Lifting t type shank of bolt, the t type head of t type shank of bolt is fixed with anchoring crab bolt, upper weld sleeve cap；Debris around cleaning bolt, check welding quality, bolt position are checked, construction finishes.Although this technical scheme has reached raising work efficiency, the purpose reducing supplies consumption and reducing construction cost, the pre-buried precision of its t type bolt collar is not fully up to expectations.
Therefore known t type sleeve bolt split burial and construction method has above-mentioned a variety of inconvenience and problem.
