Abstract
The utility model discloses a large pipe truss for marine and offshore engineering. The large pipe truss comprises cross rods and inclined brace rods, wherein the cross rods and the inclined brace rods are supported by pile legs. The large pipe truss is characterized in that the intersecting positions of various rods are connected through short pipe joints; each short pipe joint comprises a main circular pipe segment and a branch pipe segment, the main circular pipe segment is in cup joint onto one pile leg or one cross rod, and the branch pipe segment extends outwards from the outer column surface of the main circular pipe segment and is used for cup joint with other intersected rods. Due to the short pipe joints, the truss structure is simplified, and further the installation of the pipe truss is simplified. The manufacturing precision and the construction speed of the pipe truss are greatly increased, the construction difficulty is reduced, and the cost is significantly controlled.
Description
Technical field
The present invention relates to, more particularly, relate to the improvement of the Large Tube truss structure in boats and ships and ocean engineering.
Background technology
Under prior art, in boats and ships and the construction of ocean engineering product, having part-structure is Large Tube truss structure.The installation of Large Tube truss and location, construction key point is to pass through mutually (note: pipe tube head and other seams that pipe outer tube wall is angled to be produced while being connected, tube and tube is non-to be run through) while managing connection, installation bedding-in and the welding of intersecting mouth.Due to the restriction of technical merit and working accuracy, zero finishing, when intersecting mouth is installed, cannot be accomplished in camp site at present, need to be according to the on-the-spot secondary bedding-in of positioning gap.Therefore in work progress, Major Difficulties is as follows: 1, aerial bedding-in difficulty; 2, the bad control of locating data; 3, the welding of aerial intersecting mouth difficulty.
The way of prior art be by main tubular construction directly stand, sealing, in intersecting mouth position, burn postive stop baffle, connection pipe directly closes up, after locating by postive stop baffle, on-the-spot bedding-in intersecting mouth, high-altitude bedding-in is more difficult, gap is also difficult to ensure card, final welding is difficult especially, and welder's qualification requirement is quite high, flaw detection and also corresponding increasing of construction cost.
Summary of the invention
The present invention is directed to the problem in the past existing, truss structure is split as to several plane frameworks, the source nipple (typical node) of 500～1000 length on each plane framework band, by the use of source nipple, make the assembling of truss structure on ground, to complete all plane frameworks, plane framework is located to sealing, finally with straight tube, connect the source nipple on plane framework, complete finishing operation, therefore reduce assembly cost, reach the object of simplifying assembling procedure.
In order to achieve the above object, the invention provides a kind of Large Tube truss for boats and ships and ocean engineering, comprise the cross bar and the hound that by spud leg, are supported, the position that various rod members pass through is mutually connected by source nipple; Described source nipple comprises a main pipe section being socketed on spud leg or cross bar, and a pipeline section that passes through mutually rod member for being socketed other of the outside expenditure of described main pipe section outer cylinder.
Under optimal way, the position of passing through mutually at described spud leg and cross bar, the main pipe section of described source nipple is the pipe part being socketed on spud leg, the pipeline section that the corresponding part that is socketed on described cross bar is described source nipple.
In addition, a pipeline section for described source nipple connects branched pipe, for being socketed the hound of Large Tube truss.
The present invention, by the use of source nipple, has simplified truss structure, and its beneficial effect is,
1. simplify the installation of pipe truss (as single-point support, jacket etc.);
2. truss point of attachment is disconnected, by space mounting, become level land and install, then assemble;
3. aloft work is converted into non-aloft work, is convenient to precision and controls, improve safety, reduce Large-scale Hoisting operation.
The present invention has increased substantially precision and the speed of application of pipe truss fabrication, has reduced difficulty of construction, has obtained significant control on cost, at boats and ships and ocean engineering market, is worthy to be popularized.

The specific embodiment
As shown in Figure 6, a kind of schematic diagram of implementing structure of Large Tube truss of the present invention, improvement of the present invention is, the position that spud leg, cross bar or hound pass through is mutually connected by source nipple.As Figure 1-4, source nipple comprises a main pipe section (shown in Fig. 1) being socketed on spud leg or cross bar, and a pipeline section 8 that passes through mutually rod member for being socketed other of the outside expenditure of described main pipe section 7 outer cylinders.
Wherein, the position of passing through mutually at spud leg and cross bar, the main pipe section of source nipple is the pipe part being socketed on spud leg, the pipeline section that the corresponding part that is socketed on cross bar is source nipple.
In Fig. 4, when source nipple is positioned at junction, spud leg end, the end of its main pipe section is sealing end.In addition, the pipeline section of source nipple as required, can connect the branched pipe of socket hound, as the branched pipe 9 in Fig. 3.
In Fig. 7, provided the occupation mode of source nipple, number in the figure B is docking port, and label C is intersecting mouth.Fig. 8 has shown the installation clamping fixture structure of source nipple, and in figure, label 1 is spud leg; Column and stull that label 2 is positioner structure, be intended to support pile leg structure; Label 3 is ground muscle, and label 4 is cement flooring.
The present invention, by the improvement of structure, can be split as truss structure several plane frameworks, the source nipple (typical node) of 500～1000 length on each plane framework band.On ground, assembled after all plane frameworks, plane framework has been located to sealing, finally with straight tube, connected the source nipple on plane framework, completed finishing operation.Specific construction flow process is as follows:
1, according to constructional feature and actual production place, split structure.
2, make jig frame special, assembling plane framework (as shown in Figure 5).
3, typical node location, makes location tire according to gross data, by total station data, monitors and jig frame special is spacing completes assembling.
4,, after plane framework completes, the group position of halting, connects the typical node on plane framework with straight tube.
5, integral manufacturing completes.
By the enforcement to above-mentioned flow process, and each link data is monitored in real time, comprise the source nipple on plane framework, during final assembling, only weld the straight choma seam of straight tube and source nipple, difficulty of construction and construction volume reduce greatly, precision is also easily controlled, and key point is to control well the data of the source nipple on plane framework.
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; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
