Embodiment 1

[0035] The installation method of the integral sleeve of the equipment foundation T-bolt diameter ≤ 48mm of the present invention adopts a process flow: measuring and setting out → pre-embedded iron parts on the cushion layer → bottom steel bar construction → installing the center line frame → installing the T-bolt sleeve Support frame→T-bolt sleeve installation→superior reinforcement construction→T-bolt sleeve retest→pour concrete→T-bolt sleeve retest again.

[0036] The integral sleeve installation method of the equipment foundation T-bolt diameter ≤ 48mm of the present invention comprises the following steps:

[0037] a. Pre-embedded (pre-installed) iron parts:

[0038] According to the center position of the sleeve on the design drawing, pre-embed the iron parts on the foundation floor cushion. If it is on the top plate of the foundation, pre-install iron parts on the formwork. When using steel formwork, it is fixed by welding, and when using wooden formwork, it is connec...

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 [0001] The invention relates to a sleeve installation method in the pre-embedded construction of equipment foundation bolts, in particular to an integral sleeve installation method with a T-shaped bolt diameter ≤ 48mm. Background technique [0002] The anchor bolts of some metallurgical industrial equipment are detachable, that is, the anchor bolts are not directly anchored in the foundation concrete, but anchored in T-bolt sleeves ("T-bolt sleeves" hereinafter referred to as "sleeves") , The sleeve is constructed together with the foundation, directly anchored in the foundation, and the T-bolts are inserted into the sleeve when the equipment is installed, and the T-bolts can be removed from the sleeve when the equipment is replaced. [0003] The upper part of the T-shaped bolt is a screw, and the bottom end is a T-shaped head. It is equipped with a sleeve with an anchor plate, and the fastening device is installed by the anchoring force between the T-shaped ...
