Abstract

The utility model relates to an engineering apparatus, in particular to a steel pipe grouping device of a pipe truss. The steel pipe grouping device comprises a lining pipe, a rib plate and a connection plate, wherein both ends of the lining pipe are welded and fixed after respectively extending to two to-be-assembled steel pipes of the pipe truss; the rib plate is welded on the side wall of the steel pipes of the pipe truss in the axis direction; and the connection plate is connected with both sides of the rib plate. When he steel pipe groups of the pipe truss can be assembled easily and conveniently only by mounting the lining pipes in the two steel pipes for welding and fixation and then connecting and fixing the rib plate by the connection plate. The lining plates are permanently placed inside the steel pipes so as to play a role in welding, backing and strengthening, thereby achieving reliable and stable connection. The thicknesses of the rib plate and the connection plate can be appropriately adjusted according to the diameters of the steel pipes. Accordingly, the steel pipe grouping device is economic, practical and convenient.

Description

Pipe truss steel pipe is to device

Technical field

The utility model relates to a kind of engineering equipment, relates in particular to a kind of device of truss steel pipe to usefulness that be used to manage.

Background technology

Along with China's constant development of economy, a large amount of venue engineerings such as airport terminal in all parts of the country, exhibition hall, sports palace successively start, the span of these venues is generally bigger, and in order to satisfy the requirement of longspan structure, the venue engineering often adopts the pipe trussed construction.Because of the pipe truss span is big, the engineering time is short, is convenient to produce in factory and is used widely.The span of pipe truss is generally bigger, in pipe truss fabrication process, often needs special facility to guarantee to manage carrying out smoothly of truss fabrication at present, and this special implement structure is complicated, manufacturing cost is higher.

Summary of the invention

At the problems referred to above, the purpose of this utility model be to provide a kind of simple in structure, easily make and pipe truss steel pipe that cost is low to device.

For achieving the above object, the technical scheme that the utility model is taked is: a kind of pipe truss steel pipe is to device, its difference is: it includes internal lining pipe, gusset, junction plate, welding was fixing after the internal lining pipe two ends were stretched in two pipe truss steel pipes that need assembly unit respectively, pipe truss steel pipe sidewall is welded with gusset along axis direction, and the gusset both sides all are connected with junction plate.

Described gusset is arranged to rare four, and every pipe truss steel pipe sidewall welds two gussets and evenly distribution at least, keeps being straight line with right gusset on two pipe truss steel pipes, and collinear gusset connects with junction plate on the different pipe truss steel pipes.

Described gusset, junction plate correspondence are provided with connecting hole, and the connection hole is fastening with Bolt Connection.

The utility model is in the steel pipe of mounting pipe truss during to assembly unit, and it is fixing only to need that internal lining pipe is installed in two steel pipes welding, connects fasteningly then with junction plate, gusset, installs simple and convenient, economical and practical; Internal lining pipe forever is stored in the effect that steel duct plays welding backing and reinforcing, makes connection reliable and stable; The thickness of gusset and junction plate can suitably be regulated according to the size of diameter of steel tube, and it is convenient to use.

Description of symbols among the figure: 1-pipe truss steel pipe, 2-internal lining pipe, 3-junction plate, 4-gusset, 5-bolt.

The specific embodiment

In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1 and Fig. 2:

A kind of pipe truss steel pipe of implementing by the utility model comprises internal lining pipe 2, gusset 4, junction plate 3 to device, internal lining pipe 2 external diameters are less than pipe truss steel pipe 1 internal diameter, earlier internal lining pipe 2 is enclosed in an end of the pipe truss one side steel pipe that needs assembly unit, the length that internal lining pipe 2 is entered is half of self, spot welding is fixed, and then will need the other end of the pipe truss opposite side steel pipe socket of assembly unit at internal lining pipe 2, the group of adjusting steel pipe is to gap and straightness accuracy, the gap of general both sides steel pipe remains on 5mm, is convenient to the weldquality grade and reaches one-level or secondary.After adjustment finishes, that internal lining pipe 2 is fixing with the welding of opposite side steel pipe.At least two gussets 4 of corresponding respectively welding on the steel pipe of both sides, gusset 4 is parallel to the axis direction setting of pipe truss steel pipe 1, and evenly distributing, it is stressed even to make, and keeps being straight line with right gusset 4 on two pipe truss steel pipes 1, then collinear gusset 4 usefulness junction plates 3 is connected.Ways of connecting adopts bolt 5 to connect, and gusset 4, junction plate 3 correspondences are provided with connecting hole, and the connection hole is fastening with bolt 5.Gusset 4 is total up to four in the present embodiment, and every side steel pipe welds two and evenly distribute, and so just makes when junction plate 3 bears any direction power, can both evenly share, and has improved the reliability that connects.

Internal lining pipe 2 plays the effect of welding backing in welding process, will forever be stored in the inside of steel pipe with the pipe truss after the welding, plays reinforcement effect.The thickness of gusset 4 and junction plate 3 can suitably be regulated according to the size of diameter of steel tube, to be suitable for different occasions.The group of same box section is suitable for too to the utility model.The utlity model has simple in structure, make and the low characteristics of cost easily.And economical and practical, help applying.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
