Abstract

The utility model belongs to the technical field of main basic steel grating technique and specifically relates to a novel main steel grating plate bearing structure that becomes, including distributing a plurality of concrete piers, a plurality of steel grating plates of arranging into the array in the main oil tank that becomes, its characterized in that: in the array formed by arranging the concrete piers, the center row spacing is 5/96-1/16 of the width of the main transformer oil pool, and the center row spacing is 3/44-1/10 of the length of the main transformer oil pool; four corners of each steel grating plate are placed on 4 adjacent concrete piers. Compared with the prior art, the utility model cancels the method of embedding the channel steel in the concrete pier, and reduces the construction difficulty of the embedded channel steel; the embedded channel steel is cancelled, and the steel grating plate is placed in a form of the encrypted concrete pier, so that the engineering cost is reduced.

Description

Novel main steel grid plate supporting structure that becomes

Technical Field

The utility model belongs to the technical field of the basic steel grating technique that becomes, specifically speaking is a novel main steel grating board bearing structure that becomes.

Background

At present, referring to fig. 1 to 2, the existing main steel grating arrangement form of a transformer substation:

building concrete piers 2 through which long channel steel 2-1 is embedded longitudinally and transversely on a main transformer oil pool 1, wherein the top elevation of the channel steel 2-1 is flush with the concrete piers, and a steel grating plate is placed on the embedded channel steel;

in the oil sump 1 that becomes the owner, avoid the position that becomes the owner and become the basis, indulge transverse separation 1 meter and set up a concrete mound, because concrete mound 2 is smaller, and the size is 200mm (length) 200mm (width) 200mm (height), still need pre-buried channel-section steel 2-1 that leads to long when the pouring, the construction degree of difficulty is very big, and channel-section steel 2-1 also is difficult to make level, and it is leading to long channel-section steel to all pre-buried to indulge transversely, and the expense is also high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the pre-buried shortcoming of arranging the system that the construction degree of difficulty is big, the channel-section steel is difficult for making level, the expense is high of concrete mound and channel-section steel among the traditional owner basic structure that becomes, providing a novel owner who reduces the construction degree of difficulty and expense become steel grid plate bearing structure.

In order to realize above-mentioned purpose, design a novel main steel grid plate bearing structure that becomes, including distributing a plurality of concrete piers, a plurality of steel grid plate that arrange into the array in main oil sump, its characterized in that:

in the array formed by arranging the concrete piers, the center row spacing is 5/96-1/16 of the width of the main transformer oil pool, and the center row spacing is 3/44-1/10 of the length of the main transformer oil pool;

four corners of each steel grating plate are placed on 4 adjacent concrete piers.

Furthermore, the center line spacing between two adjacent rows of concrete piers on the frontmost side and the center line spacing between two adjacent rows of concrete piers on the rearmost side are respectively less than or equal to the center line spacing between adjacent concrete piers on the other middle lines.

Further, the center row distance between two leftmost columns of adjacent concrete piers and the center row distance between two rightmost columns of adjacent concrete piers are respectively less than the center row distance between the other middle columns of adjacent concrete piers.

Furthermore, corresponding side walls of a plurality of concrete piers positioned at the outermost side are attached to the inner wall of the main transformer oil pool.

Compared with the prior art, the utility model cancels the method of embedding the channel steel in the concrete pier, and reduces the construction difficulty of the embedded channel steel; the embedded channel steel is cancelled, and the steel grating plate is placed in a form of the encrypted concrete pier, so that the engineering cost is reduced.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and examples.

Example 1

Referring to fig. 3 to 4, a novel main transformer steel grating plate supporting structure comprises a plurality of concrete piers and a plurality of steel grating plates which are arranged in an array, in this example, a main transformer oil pool which is 11000mm long and 9600mm wide is taken as an example, wherein corresponding side walls of a plurality of concrete piers 2 which are positioned at the outermost side are attached to the inner wall of the main transformer oil pool 1, the row spacing of the concrete piers in the array which are arranged is the same as the original row spacing, namely, the center distance from the center of the left side wall and the center of the right side wall of the main transformer oil pool to the nearest concrete pier 2 is respectively 200mm, and the center row spacing (unit: mm) of the other middle rows of concrete piers is 750, 1000, 1100, 900, 1100, 1000, 75 and 75 in sequence; the line spacing is more dense than before, and is respectively: the center distances from the centers of the front and rear side walls of the main transformer oil pool 1 to the nearest concrete piers 2 are respectively 200mm, and the center line distances (unit: mm) of the other middle concrete piers are as follows: 500. 500, 600, 500, 600, 500;

the four corners of each of said steel grid plates are then placed on the adjacent 4 concrete piers 2.

In practical use, a pebble layer with the thickness of 250mm is paved on the steel grating plate.
