Problems solved by technology

Due to the influence of grinding precision, the joint surface between the flat backing plate and the foundation surface is incomplete, resulting in uneven contact and affecting the stability of the foundation. If you want to achieve better contact precision, you need a good fitter technician to do it. Serious grinding and adjustment requires a lot of time and technical strength
The slurry seat method is a common method for installing the backing plate of the existing equipment foundation. In the process of aligning the backing plate, tools such as rubber hammers are used to level the backing, which is easy to remove and difficult to install, and it is easy to cause rework, and damage to the backing Inaccurate control of slab elevation
The installation process of equipment without a backing plate is widely used abroad. Since there is no backing plate to support the equipment, the requirements for the grouting material at the bottom of the equipment are very high. The existing domestic quick-drying grouting materials are still difficult to meet the requirements of high-strength impact. rarely used

Embodiment Construction

[0018] The rapid construction method of the foundation pad of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] 1. Construction preparation

[0020] 1) Backing plate processing: Prepare necessary grouting materials, auxiliary materials and tools according to the size of the project and equipment installation requirements, select a flat backing plate that meets the specifications, and weld a piece of about 120*60*10mm steel plate, open a φ18mm round hole in the center of the steel plate, see Figure 1. Also can determine the size of the fixed steel plate that bottom adjusting bolt is used according to the actual size of backing plate.

[0021] 2) Determination of elevation: It is directly related to the installation height of the backing plate and the coordinate position of the equipment, and it is required to be easy to measure and adjust.

[0022] 3) Inspection of the foundation: the original secondary grouting la...

Abstract

It relates to the close binding of the bottom plate and the base of equipments in installation and maintenance. The screw adjusting method for basic overlay plate goes like this: a. overlay plate processing by welding a piece of steel plate for each of the four corners of the selected qualified flat overlay plate with holes in the middle of the steel plates. B. determining the height mark. c. inspect the basics by eliminating the original secondary grout blanket with the backbone of the first layer exposed and the distance between the lower surface of the flat overly plate and the original concrete layer 120-180mm. d. install the overlay plate by welding the angle steel to the backbone of the basics and welding the bolts on the flat overly plate after positioning based on the technical specifications of the flat overlay plate. E. installs the equipment. It can work a lot of work with simple process and within short time.

Description

technical field [0001] The invention belongs to the technical field of installation and maintenance engineering requiring the close combination of the equipment bottom plate and the foundation. Background technique [0002] The current equipment installation includes three methods: equipment installation backing grinding method, equipment installation seat slurry method and equipment installation without backing board. Due to the influence of grinding precision, the joint surface between the flat backing plate and the foundation surface is incomplete, resulting in uneven contact and affecting the stability of the foundation. If you want to achieve better contact precision, you need a good fitter technician to do it. Serious grinding and adjustment requires a lot of time and technical strength. The slurry seat method is a common method for installing the backing plate of the existing equipment foundation. In the process of aligning the backing plate, tools such as rubber ham...
