Abstract
The invention relates to the technical field of large-scale metal storage tank mounting, in particular to a method for calculating the amounts of cross beams and upright posts of a large-scale metal storage tank floating pontoon bracket. The method comprises the following steps: I, the projected area A1 of the tank bottom of a large-scale metal storage tank is calculated out according to the radius of the large-scale metal storage tank, and the upper flat area of a platform of the floating pontoon bracket is A1; II, six cross beams are connected to the upper end of each upright post of the floating pontoon bracket in an isogonic manner, and both ends of each cross beam are connected with upright posts; III, the area of an equilateral triangle formed by three adjacent cross beams is A2; IV, the amount of upright posts required by the floating pontoon bracket is B1, wherein B1=A1/A2*1/2; V, the amount of cross beams required by the floating pontoon bracket is B2, wherein B2=A1/A2*3/2. The method has the advantages that the amounts of the cross beams and the upright posts of the large-scale metal storage tank floating pontoon bracket can be calculated out simply and accurately; the work efficiency is improved.
Description
Technical field:
The present invention relates to a kind of large-scale metal storage tank field engineering field, particularly a kind of crossbeam of large-scale metal storage tank pontoon support and the quantity computation method of column.
Background technology:
Large-scale vertical steel storage tank is the very important warehousing and transportation facilities of petroleum chemical industry, more and more for crude oil, finished product wet goods transmisson and storage project.The type of storage tank has a lot, widespread use be large-scale vertical steel cylinder shape Dome roof tank and floating roof tank.The construction of large-scale vertical External floating roof tank is main adopts upright method of hull section construction and upside-down construction, " interior framing scaffold upright method of hull section construction " construction is adopted to be construction method the most general during large-scale storage tank is installed, the installation of pontoon is particularly important, setting support platform is needed when pontoon is installed, pontoon rack platform is primarily of crossbeam and column composition, and its mounting process and tooling fixture huge number used, be difficult to calculate, the quantity that research correlation technique calculates crossbeam and column needed for large-scale storage tank pontoon rack platform tooling device is necessary.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of crossbeam of large-scale metal storage tank pontoon support and the quantity computation method of column, the method achieve and can calculate the crossbeam of large-scale metal storage tank pontoon rack platform and the quantity of column simply, exactly, increase work efficiency.Overcome the crossbeam of existing large-scale metal storage tank pontoon rack platform and column substantial amounts, be difficult to the deficiency that calculates.
The technical solution used in the present invention is: a kind of crossbeam of large-scale metal storage tank pontoon support and the quantity computation method of column, and the method step is as follows:
One, projected area A at the bottom of tank is calculated according to the radiuscope of large-scale storage tank
1, on pontoon rack platform, the area of plane is A
1;
Two, every root post upper end of pontoon support angularly connects 6 crossbeams, and every root crossbeam two ends all connect column;
Three, the area of equilateral triangle that 3 adjacent beams form is A
2;
Four, the quantity B of column needed for pontoon support
1be calculated as follows: B
1=A
1/ A
2× 1/2;
Five, the quantity B of crossbeam needed for pontoon support
2be calculated as follows: B
2=A
1/ A
2× 3/2.
The invention has the beneficial effects as follows: the present invention can calculate the crossbeam of large-scale metal storage tank pontoon rack platform and the quantity of column simply, exactly, increases work efficiency.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
Fig. 1 is column and the crossbeam connection diagram of pontoon rack platform.
Embodiment:
As shown in Figure 1, a kind of crossbeam of large-scale metal storage tank pontoon support and the quantity computation method of column, the method step is as follows:
One, projected area A at the bottom of tank is calculated according to the radiuscope of large-scale storage tank
1, on pontoon rack platform, the area of plane is A
1;
Two, every root post upper end of pontoon support angularly connects 6 crossbeams, and every root crossbeam two ends all connect column;
Three, the area of equilateral triangle that 3 adjacent beams form is A
2;
Four, according to metal lattice structural theory, every root post is connected with 6 crossbeams, then each column is that 6 crossbeams are common, therefore only has 1/6 to belong to this triangle, so each triangle has 3 × 1/6 columns, then and the quantity B of column needed for pontoon support
1be calculated as follows: B
1=A
1/ A
2× 1/2;
Five, the quantity B of crossbeam needed for pontoon support
2be calculated as follows: B
2=A
1/ A
2× 3/2.
The present invention uses when adopting " interior framing scaffold upright method of hull section construction " to construct mainly for large-scale storage tank.
Be understandable that, above about specific descriptions of the present invention, the technical scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
