Problems solved by technology
The unevenness of the bottom of the tank will affect the quality of the anti-corrosion lining in the subsequent process
[0003] There are many parts and components in the foundation construction of the bottom of conventional tanks, and the unified adjustment of the flatness of the entire long I-beam several meters long during construction is not only labor-intensive, but also the flatness error of the installation is difficult to control

Embodiment Construction
[0015] The following combination figure 1 and figure 2 The present invention is further described.
[0016] The construction method of the foundation structure at the bottom of a large-scale anti-corrosion tank is characterized in that the steps are:
[0017] a) According to the width requirements of the steel floor 6 to be laid, pre-embedded screw rods 1 are arranged in pairs, directly welded on the foundation steel bars, and after checking that the angle and elevation are correct, the concrete foundation is poured to fix the position of the pre-embedded screw rods 1;
[0018] b) An upper nut 4 and a lower nut 2 are placed at the end of the exposed part of the pre-embedded screw 1, and an adjustment steel plate 3 is placed between the upper nut 4 and the lower nut 2, and the height of the lower nut 2 is finely adjusted in turn until the adjustment The height of the upper surface of the steel plate 3 meets the technical requirements of the drawings, the lower nut 2 and the ...

The invention relates to a construction method of bottom plate foundation architecture of a large desulfurization anti-corrosion storage tank or storage case. The method includes the steps that: a) screws are uniformly arranged in pair, welded, fixed and embedded according to width requirement of a steel bottom plate to be paved; b) the end part of the exposed part of the embedded screws is provided with upper nuts and lower nuts; wherein an adjusting steel plate is arranged between the upper nuts and the lower nuts, and the lower nuts are sequentially finely adjusted until the height of the upper surface of the adjusting steel plate accords with drawing technical requirements; c) grating strips are fixed on the adjusting steel plate by welding; d) concrete foundation is formed below the grating strips by final grouting, and a storage tank bottom plate is paved on and is fixedly connected with the reticular grating strips by welding. The invention has the beneficial effects that: standard height of the adjusting steel plate can be conveniently adjusted by sequentially finely adjusting the lower nuts at the end part of the embedded screws, further flatness error of the whole grating plate mesh can be controlled, the problem that the flatness of the case and tank bottom plate exceeds standard is effectively overcome, and thread adjustment is convenient and accurate.
Description
technical field [0001] The invention belongs to the technical field of tank manufacturing for desulfurization equipment, and relates to a base structure of a large-scale storage tank or a base plate of a storage tank, in particular to the base of a large-scale tank that requires anti-corrosion treatment with high requirements on the quality of the base plate. method of construction of the structure. Background technique [0002] Usually, the bottom foundation structure of large-scale anti-corrosion tanks is to use I-shaped steel or channel steel as the longitudinal and horizontal grid-like separation of the entire bottom surface. The beams are welded and fixed in sections, and the lower edge of the I-beam of the floor beam is fixedly connected with the civil concrete casting layer below the bottom of the storage tank through embedded screws. The bottom plate is laid on the bottom plate beam and fixed by welding, and finally the anti-corrosion rubber lining is made inside th...
