Abstract
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
The invention belongs to desulphurization plant case jar manufacturing technology field, relate to a kind of large-scale storage tank or storage tank mat foundation structure, relate in particular to the job practices of foundation structure of the demanding need of mat foundation quality requirement, particularly planeness being made the Large Box jar of anti-corrosion treatment.
Background technology
Usually, large anticorrosion erosion case pot bottom foundation structure is the vertical, horizontal clathrate to be made with i iron or channel-section steel in whole bottom surface separate, as vertically with the long i iron of whole piece as floor beams, side laterally is welded to connect fixing with short channel-section steel and vertical long i iron segmentation, fixedly connected with the civil engineering concrete casting cast layer of storage tank pot bottom below by pre embedded bolt in the lower edge of floor beams i iron.Base plate is laid on the floor beams and welding is fixed, and makes the anticorrosion rubber lining in case jar inside at last, or coated glass scale clay.The out-of-flatness of case pot bottom will influence the quality of subsequent handling Corrosion resistant linings.
Conventional case pot bottom foundation construction component are various, and the long i iron of several meters long whole piece is unified in the construction adjusts not only labour intensity height of flatness, and the flatness error of installing is difficult to control.
Summary of the invention
The objective of the invention is in order to overcome the disadvantage of prior art, provide a kind of embedded part structure succinct, regulate light accurately, can effectively control the job practices of base foundation structure of the case jar of the flatness error that base plate installs.
For achieving the above object, the technical scheme of employing is: the job practices of bottom foundation architecture of large desulfurization anti-corrosion case and tank is characterized in that: step is:
A) by the width requirement of steel sole plate to be laid, the uniform pre embedded bolt that is provided with directly is welded on the reinforcement foundation in pairs, checks that the errorless back pouring of angle absolute altitude concrete basis makes described pre embedded bolt fixed-site;
B) the exposed part end of pre embedded bolt is equipped with top nut and lower nut, be equipped with the adjustment steel plate between described top nut and the lower nut, finely tune each lower nut successively, meet the drawing technical requirements until described adjustment steel plate upper level, described lower nut and described pre embedded bolt spot welding are fixed, and tighten the top nut location;
C) on described adjustment steel plate, arrange the grid lath, prescind described pre embedded bolt and exceed grid lath upper surface portion, the grid lath is fixing with the welding of adjustment steel plate, be connected into netted integral body by welding manner between the grid lath, thereby reach the flatness error of controlling whole grid expanded metals effectively;
D) final grouting concrete basis, described grid lath below, netted described grid lath upper berth is established the case tank bottom and is welded to each other and is connected and fixed.
Described pre embedded bolt is the L sigmoid.
The invention has the beneficial effects as follows: L type pre embedded bolt and to adjust the steel plate combined member uniform and symmetrical, can adjust the absolute altitude of steel plate easily and contain the drawing technical requirements by finely tuning lower nut successively to according with.Threaded adjusting is light accurately and since the design arrangement of grid lath be horizontal, indulge mode, be netted, so and then can control the flatness error of whole grid expanded metals, effectively overcome problems such as case tank bottom flatness exceeds standard.
Description of drawings
Fig. 1 is a Large Box tank bottom structure chart;
Fig. 2 is the B-B cross-sectional view of Fig. 1.
Among the figure, 1, pre embedded bolt; 2, lower nut; 3, adjust steel plate; 4, top nut; 5, grid lath; 6, base plate.
The specific embodiment
The invention will be further described below in conjunction with Fig. 1 and Fig. 2.
The job practices of large anticorrosion erosion case pot bottom foundation structure, it is characterized in that: step is:
A) by the width requirement of steel sole plate to be laid 6, pre embedded bolt 1 is set in pairs, directly is welded on the reinforcement foundation, check that the errorless back pouring of angle absolute altitude concrete basis makes described pre embedded bolt 1 fixed-site;
B) the exposed part end of pre embedded bolt 1 is equipped with top nut 4 and lower nut 2, be equipped with between described top nut 4 and the lower nut 2 and adjust steel plate 3, finely tune lower nut 2 successively and regulate height, meet the drawing technical requirements until described adjustment steel plate 3 upper level, lower nut 2 is fixed with pre embedded bolt 1 spot welding, tightens top nut 4 location;
C) on described adjustment steel plate 3, arrange grid lath 5, prescind described pre embedded bolt 1 and exceed described grid lath 5 upper surface portion, grid lath 5 is fixing with 3 welding of adjustment steel plate, be connected into netted integral body by welding manner between the grid lath 5, thereby reach the flatness error of controlling whole grid expanded metals effectively;
D) final grouting concrete basis, described grid lath 5 below, treat that case jar body installs after, last install bin tank bottom 6.For the flatness of finally guaranteeing case tank bottom 6 reaches technical requirements, lay and be welded to connect fixed base plate 6 on the netted described grid lath 5, strict order according to past both sides from the center, base plate 6 and flase floor bar 5 are fused.
For convenient pre-buried in having the concrete civil engineering layer of reinforcing bar, described pre embedded bolt 1 is the L sigmoid.
