The installation speed of steel structure warehouse is fast and
equally reliable

Steel structure is a structural composed of steel materials,
which is one of the main building structure types. Steel structure warehouses installation quickly ,
the structure is mainly composed of steel beams, steel columns, steel trusses
and other components made of shaped steel and steel plate, etc., and usually
welded, bolted or riveted joints are used between each member or component ,
because of its light weight and simple construction, is widely used in large
factory buildings, venues, super high-rise and other fields.

1. Before the steel structure is installed, all kinds of records
and reports should be checked, such as quality certificate of components,
material test report, non-destructive inspection report of welding seam, etc.,
and the appearance of components should be checked to see if they conform to the
design requirements, and the problems should be corrected
immediately.

2. The installation flow chart of the steel structure is drawn
and installed according to the flow chart. The precision of all anchor bolts
should be checked before installation, and the spatial position and design
drawing should be corrected timely to ensure the accuracy of anchor
bolts.

3. The mounting sequence of the components should be carefully
designed to form a rigid body as soon as possible so that the installation can
be continued in a stable state, and also to eliminate errors in the installation
of the steel structure.

4. Component assembly should undertake the necessary checking
calculation. The lateral stiffness of small component measures should be taken
to avoid the distortion and damage.

5. In the process of columns or steel structure installation,
beam and steel support should be installed in a timely manner, temporary fixed
cable wind rope should be added when necessary.

6. It should pay attention to controlling the influence of
temperature difference on the perpendicularity of components for the
installation of steel column, adjust the lateral quantity to the
perpendicularity of the first determined standard column, and check other
columns.

7. When the column is installed, the positioning axis of each
column must be directly drawn from the control axis on the ground, and the top
axis of the column of the next column shall not be used as the positioning axis
of the upper column.

8. Steel structure installation spot welding environment,
welding position, high altitude, air temperature and humidity adverse effects
for susceptible to weld defect, therefore, must take appropriate measures to
overcome the impact of these unfavorable factors. The unqualified weld rework
repair is not allowed to exceed twice.

9. High strength bolts using torque wrench must be correction
calibration before use, should check after use, once found that the torque error
exceed the permitted range, the twist of the wrench bolt were all
unqualified.

The high-strength bolts should be tested after final screw, and
the nuts can be tested one by one by means of small hammering. Torque should
also be sampled check.

10. After the Steel structure installation is completed, and
correct after correction, it should do the second grouting in time for the space
between the column bottom and top of the base to make sure the surface contact
base plate and foundation top tight.

11. After completion of the whole steel structure installation,
it should be according to “the steel structure engineering construction quality
acceptance standard “(GB 50205-2001) requirements for acceptance.
