Abstract
The invention discloses an inclined support for a single-point mooring manifold platform main body, and each inclined support comprises a first section, a second section and closure plates on two ends; in order to solve the problem that the inclined support cannot be installed after a framework is formed, a first section Z-shaped interface and a second section Z-shaped interface are adopted, and an installation sequence for installing the second section after the first section is installed is adopted; the closure plates 3 are adopted, so that the phenomenon that the inclined support cannot be welded because of small space on the junction of a main framework can be solved; and the closure plates and a framework web form a closed space, so that the difficult links for filling sand and coating in the subsequent step of an open space can be saved. The inclined support is simple in structure and convenient to produce, and the problem that the weld seam is overlapped, the welding cannot be carried out because of small space and the inclined support cannot be installed can be effectively solved.
Description
Technical field
The present invention relates to structural framing in ocean engineering and strengthen the installation method supported, particularly a kind of installation method of single point mooring system manifold platform structure chassis body bearing diagonal.
Background technology
4 parts as shown in Figure 1, single point mooring system manifold platform structure framework is 9 meters of the length with anchoring pile skirt structure, wide 9 meters, the high approximately H structural steel frame structure of 3 meters, during duty, by four anchoring pile integral body, be positioned for a long time sea bed, piping 5 parts in seabed are played a supporting role.
Considering design, production task, buying, inventories and site operation needs, is first that the HE900B of 4 parts and HE600B big frame assembly welding is complete in a lot of situations, last welded H 200B type steel support.In this case, the situation that there will be type steel support to install.Particularly the structure of this framework+support there will be the H structural steel frame web of square shape the phenomenon overlapped to occur with hypotenuse H shape steel web weld seam, and because the space angle at welding line joint place is too little, and can't welding or can't complete the complete penetration (see figure 2).
Summary of the invention
The present invention has overcome deficiency of the prior art, a kind of installation method of single point mooring system manifold platform structure chassis body bearing diagonal is provided, being intended to strengthen supporting for the HE200B hypotenuse in H structural steel frame structure provides a kind of joint style, and after capturing the main frame moulding, H shaped steel is strengthened supporting a kind of method that HE200B is assembled, thereby reach the purpose of optimizing structure, conveniently making.
In order to solve the technical problem of above-mentioned existence, realize above-mentioned purpose, the present invention adopts following technical proposals:
A kind of installation method (see figure 4) of single point mooring system manifold platform structure chassis body bearing diagonal, it comprises following concrete steps:
(i) bearing diagonal comprises that 1,2 section and two ends are provided with shrouding 3, and at first a kind of joint style is provided, and increases thick high-strength plate is installed, and makes the shrouding of subframe intersection form enclosure space in order to avoid follow-up sanding is sprayed and exerts an influence with the framework web;
(ii) according to web and the flange plate of zigzag otch cutting HE200B H shaped steel, making 1,2 segment interfaces is zigzag; During installation, the erection sequence of 1,2 section is first after 1 section 2 sections, first by 1 section location of HE200B, because the top flange plate of H shaped steel is less than the lower wings listrium, can't install from top for 2 sections, location upwards need be installed in its bottom from framework, last complete penetration.
The invention provides a kind of joint style, the high-strength plate 3(peculiar to vessel that has increased suitable thickness of slab is shown in Fig. 3).In addition, in the situation that main frame assembles is complete, because HE200B web catercorner length is greater than the framework catercorner length, can't install for whole, HE200B is cut according to zigzag, substep is installed on main frame, and is welded (see figure 4).The connection of above-mentioned all parts all connects with welding manner.
Owing to adopting technique scheme, joint form provided by the invention and bearing diagonal installation method compared with prior art have such beneficial effect:
The present invention is simple in structure, easy to make, can effectively ensure the quality of products, and reduces costs.
The accompanying drawing explanation
Fig. 1 is manifold main platform body structural representation;
Fig. 2 is initial joint design schematic diagram;
Fig. 3 is the improved structure of connector schematic diagram of Fig. 2;
Fig. 4 is that HE200B strengthens supporting the installation method schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail:
As shown in Figure 1, manifold platform main frame is that the H shaped steel by several specifications is spliced, and wherein main frame is comprised of subframe again.
Specifically, as shown in Figure 4, after being formed by the H shaped steel subframe frame of HE600B, need to install the HE200B bearing diagonal.For avoiding weld seam to overlap, need to do two work before the location and installation bearing diagonal: (i) increase the thick high-strength plate of 30mm is installed, make subframe intersection form enclosure space in order to avoid follow-up sanding spraying is exerted an influence, as Fig. 3; (ii) cut web and the flange plate of HE200B H shaped steel according to the zigzag otch.Should be first by 1 section location of HE200B during installation, because the top flange plate of H shaped steel is less than the lower wings listrium, the B section can't be installed from top, location upwards need be installed in its bottom from framework, last complete penetration.
Can well solve three difficult problems according to above-mentioned steps: the problem that weld seam overlaps, narrow space can't welding and HE200B can't install.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
Claims (1)
1. the installation method of a single point mooring system manifold platform structure chassis body bearing diagonal, it comprises following concrete steps:
