Installation method caresses foundation bolts in foundations for fixing machines and equipment

 

The invention relates to the field of construction, and in particular to methods of installation of anchor bolts in the Foundation for mounting of technological equipment, including machinery and equipment with dynamic loads. The method includes forming a well. What is new is the fact that before the concrete on the Foundation bolt is within its depth or partial depth concrete array at any cross section of the well worn with subsequent fixation sleeve of porous low permeability and ascepsymase with svezheokrashennym concrete material, for example polystyrene, and the strength of the material of the sleeve must be not less than 10% of the maximum load occurring during concrete placement. The technical result of the invention is to simplify the method of forming the enclosing well around the Foundation bolt. 1 Il.

There is a method of installation of Foundation bolts, providing for the installation of meters the pipe coaxial Foundation bolt with the purpose of education according to the height of the well for subsequent straightening inside bolt at the subsequent installation of equipment (Contin A. D., Gotz, M. A. and other Rational design of foundations for industrial buildings. L.-M. stroiizdat, 1964, Fig. 79, S. 181, Fig. 80, S. 182) [1].

A disadvantage of the known solutions lies in the complexity of this method and in a large consumption of metal for the device walling well.

There is a method of installation of Foundation bolts, including the formation of the well coaxially of the axis of the anchor bolt on the whole or part of the depth of Foundation bolt ("a Guide to mounting of technological equipment Foundation bolts". M, stroiizdat, 1979, Fig. 7-9, S. 11 and table. 10, S. 35) [2].

This method has the same disadvantages.

The aim of the invention is to simplify the method of forming the enclosing well around the Foundation bolt.

For this purpose, the known method of installation of Foundation bolts in the base for mounting machines and equipment, including the formation of the well, until the concrete on the Foundation bolt is within its depth or partial depth concrete array at any cross section of the well worn with subsequent fixation sleeve of porous low permeability and ascepsymase with svezheokrashennym concrete material, for example polystyrene, etc the surrounding when laying concrete.

The drawing shows a variant of the installation of Foundation bolts in the concrete Foundation for mounting machinery and equipment.

Installation of the Foundation bolt is as follows.

On the Foundation bolt 1 with a time releasing 2 and anchor plate 3 before concreting on the depth of the well 4 wear sleeve 5, with subsequent fixation of the coupler 6. Then make the concreting of the Foundation of the machine or equipment 7. The sleeve has dimensions of future well and is made of a porous permeable and ascepsymase with svezheokrashennym concrete material, for example polystyrene. The strength of the material of the sleeve must be not less than 10% of the pressure value from svezheulozhennogo concrete. Use bushings that are installed on the Foundation bolt, of a porous permeable and ascepsymase with svezheokrashennym concrete material allows, on the one hand, to form the well 4 of a given size around the Foundation of the bolt 1 in the array of Foundation 7, and, on the other hand, during the subsequent installation of equipment without much extra effort to ratulate Foundation bolt 1 or replace it if the sleeve 5 when the installation was set the mechanical effects, arise in its lateral displacement or pulling through, the sleeve 5 made of a solid porous material, easily destroyed and does not prevent movement of the bolt. 1. Optionally, in the process of straightening bolt products of destruction of the material of the sleeve can be purged with compressed air.
