The technical solution adopted for the present invention to solve the technical problems is:
High-strength bolt hole group steel structure member makes pre-assembly method, and described steel structure member comprises steel column main part, bracket, girder steel and support, and the method comprises the following steps:
S1, be placed on pre-assembling platform by straight for steel column main part;
S2, the bracket blanking as a whole that girder steel and its two ends are connected with steel column main part, then bore template is utilized to carry out the boring of bolt hole group in the junction of girder steel and bracket, again according to drawing requirement cutting girder steel and bracket, the girder steel after then connecting cutting with bolt and bracket form girder steel assembly;
S3, the bracket blanking be as a whole connected with steel column main part with its two ends will be supported, then bore template is utilized to support the boring carrying out bolt hole group with the junction of bracket, support and bracket according to drawing requirement cutting, the support after then connecting cutting with bolt and bracket form supporting component again;
S4, according to arrangement diagram, steel column main part and girder steel assembly and supporting component to be pre-installed, measure the physical dimension of prepackage errorless after, carry out welding of steel column main part and bracket;
S5, after the bracket of all absolute altitudes has welded with steel column main part, bracket and girder steel, bolt between bracket and support are removed.
By technique scheme, step S1 is specially: more piece steel column main part is divided into two rows are straight to be placed on pre-assembling platform, the gap of reserved 5mm between the adjacent steel column main part of every two joint, and the spacing between two row's steel column main parts are fixed by behind designing requirement location.
By technique scheme, described pre-assembling platform is made by H profile steel, and it is highly greater than the height of bracket, and length and width are greater than length and the width of steel column main part.
By technique scheme, described bracket, girder steel and support are made by H profile steel.
The beneficial effect that the present invention produces is: by the bracket of each junction of steel column main part and girder steel, bracket and support Whole blanking respectively, and the boring of High-strength bolt hole group is carried out by bore template, can effectively ensure that aperture size is consistent, and then improve the perforated percentage of high-strength bolt, minimizing is done over again, simultaneously, assemble while can realizing steel structure member by the method, weld simultaneously, improve make efficiency, play very large positive role to raising labour productivity and reducing energy consumption.
