Description

A kind of cross steel pipe concrete profiled pile of assembling type steel structure

Technical field

The utility model relates to a kind of cross steel pipe concrete profiled piles of assembling type steel structure, belong to assembling type steel structure Architectural Equipment technical field.

Background technique

In recent years, under the background of national supply side reform, variety steel ratio, assembled steel knot is continuously improved in iron and steel enterprise The residential housing of structure is also grown rapidly.In assembling type steel structure building, because of the construction of steel pipe concrete profiled pile Simply, shearing resistance, tension, antidetonation and other effects preferably, are relatively mostly used.Especially with cross abnormity made of square tubes soldering The problem of column, effective solution building vertical column prominent metope, steel pipe concrete profiled pile is widely popularized.

Currently, cross steel pipe concrete profiled pile mostly uses multiple square tubes straight in assembling type steel structure architectural process It connects welding or square tube, rectangular tube and U-shaped steel is directly welded, as shown in attached drawing 1,2,3,7,8,9, wherein attached drawing 7 is four U Fashioned iron is respectively welded on four sides of a square tube, and attached drawing 8 is three sides that three U-shaped steels are respectively welded at a rectangular tube On, attached drawing 9 is the centre for two long sides that two U-shaped steels are respectively welded at a rectangular tube.These three Combination Welding mode structures At cross steel pipe concrete profiled pile have the following problems: (1) steel consumption is big, and especially multiple square tubes are directly welded It connects, plate is caused to be overlapped；(2) weld seam quantity is more, deformation is serious；(3) pore quantity after welding is more, is five in attached drawing 7, attached It is four in Fig. 8, attached drawing 9 is three, leads to the filling complexity of later process concrete, is easy to appear filling defect, of poor quality etc. Quality problems.

Therefore, the manufacturing process of the concrete filled steel tube shape tube in improvement assembling type steel structure building, raising construction quality, Building cost is saved, just at the critical issue for promoting assembling type steel structure architectural development.

Utility model content

The utility model aim is to provide a kind of cross steel pipe concrete profiled pile of assembling type steel structure, can reduce steel The usage amount of material, the pore quantity after reducing weld seam quantity and welding, guarantees the filling quality of concrete, solves in background technique There are the problem of.

The technical solution of the utility model is:

A kind of cross steel pipe concrete profiled pile of assembling type steel structure, include two U-shaped steels and an open rectangle pipe, The open rectangle pipe be the centre of a long side of rectangular tube be equipped with a gap matched with the width of U-shaped steel, one A U-shaped steel is welded on the gap of a long side of open rectangle pipe, another U-shaped steel is welded on another of open rectangle pipe In long side, section constitution is cross.

The U-shaped steel and open rectangle pipe are cold-rolled forming section or hot-rolled steel section.

The beneficial effects of the utility model are:

(1) saving steel consumption 20%, reduces building cost；

(2) weld seam quantity reduces 40% or more, and the deformation of member is small, and postwelding quality is high；

(3) pore quantity after welding is reduced to two by original three to five, reduces the filling number of concrete, Construction period has been saved, labor intensity of workers is reduced, while it is filling to can be avoided the cavity occurred in concrete pouring process Defect is conducive to improve concrete filling quality.

Specific embodiment

Below in conjunction with attached drawing, by example, the utility model is described in further detail.

Referring to attached drawing 2,6,10, a kind of cross steel pipe concrete profiled pile of assembling type steel structure, comprising two U-shaped steels and One open rectangle pipe 7, the open rectangle pipe 7 are to be equipped with the width of one with U-shaped steel in the centre of a long side of rectangular tube The gap matched is spent, a U-shaped steel is welded on the gap of a long side of open rectangle pipe 7, another U-shaped steel is welded on In another long side of open rectangle pipe 7, section constitution is cross.

Specific embodiment:

In the present embodiment, referring to attached drawing 6, open rectangle pipe 7 is to be equipped with one in the centre of a long side of rectangular tube The gap matched with the width of U-shaped steel, a U-shaped steel are welded on the gap of a long side of open rectangle pipe 7, another U-shaped steel is welded in another long side of open rectangle pipe 7, and section constitution is cross, and the pore quantity after welding is two.

Welding uses submerged-arc welding, and weld seam is one of molding, is not necessarily to bevel, forms relative to gas shield welding three, molding It is high-efficient, and each weld seam can be welded using downhand welding, it is low to worker's technical requirements.Pore quantity after welding is two, The filling number that concrete can be reduced, has saved construction period, is conducive to improve concrete filling quality.

In addition, the cross steel pipe concrete profiled pile of assembling type steel structure can also use U-shaped steel 2, angle referring to attached drawing 11 Steel 5 and W fashioned iron 6 weld, and referring to attached drawing 4,5, angle steel 5 is right angle equal leg angle, and the interior angle of W fashioned iron 6 and outer angle beta are 90 degree, Angle steel 5 and W fashioned iron 6 are that steel plate cold bending forms, and the two sides of W fashioned iron 6 are respectively welded on two right-angle sides of angle steel 5, two U Fashioned iron 2 is respectively welded at the outside of two right-angle sides of angle steel 5, and section constitution is cross, and the pore quantity after welding is three.

The above-mentioned cross steel pipe concrete profiled pile of assembling type steel structure leads to section transverse strength when pore quantity is very few When inadequate, it can be compensated using the method for increasing fashioned iron thickness.
