Abstract

The utility model discloses a supporting steel pipe reinforced vertically. The supporting steel pipe is characterized by comprising a vertical pipe in a shape of a prismatic straight pipe and fins fixed on an inner wall of the vertical pipe, and the outer edges of the fins are fixed with the inner wall in a sealing and matched mode. The fins are distributed along the length direction of the vertical pipe at intervals. By arranging the fins in an inner wall cavity of the vertical pipe, the deformation of the vertical pipe is restrained, and the integral stability and rigidity of the steel pipe are greatly improved.

Description

A kind of supporting steel pipe of vertical enhancing

Technical field

The utility model relates to the vertical support engineering equipment of constructive engineering template support system, more particularly, is a kind of steel pipe for vertical support.

Background technology

The more employing steel pipe support of formwork bracing system in construction work.Support the steel pipe of use and do not classified for building level and vertical direction used, and in actual conditions, vertical applied force is often much bigger than horizontal force, usually can not meet the demands while causing so the vertical press-bending of steel pipe stressed.This is also the major reason that causes a lot of template in construction process engineering collapse accidents.

Guarantee the rigidity of vertical supporting, if adopt existing shelf steel pipe support, inevitable requirement increases the setting of vertical steel pipe, and this not only increases the input of work progress, and can make the working space of construction reduce and increase difficulty of construction.Be used as vertical supporting if reelect the steel pipe of other model, can make like this material require of steel tube fastener arrange separately.Bring other design, Material Cost.By analyzing the phenomenon of vertical supporting steel pipe unstability in operation process, it is mainly because under Action of Gravity Field, and the steel pipe walls distortion increases.Thereby lead, make pipe deformation increase the rear flexural deformation that forms, reduce the support force at top after steel pipe bends.Thereby cause whole template system to destroy because of the vertical supporting unstability.The ultimate bearing capacity of steel pipe, because of not the reaching of distortion, therefore, is considered the compatibility with existing material, technique in other words, is necessary to invent a kind of sectional dimension identical with existing steel pipe, but the higher enhancing degree steel pipe of vertical bearing capacity.

The utility model content

For the problems referred to above, vertically to supporting steel pipe, bear hypodynamic defect for overcoming to have now, and be badly in need of the demand that possesses anti-pressure ability on the specification basis having now, the utility model proposes a kind of supporting steel pipe of vertical enhancing, its technical scheme is as follows:

A kind of supporting steel pipe of vertical enhancing, it comprises:

Vertical tube, its form is prismatic straight tube; And

Fin, be fixed in the inwall of described vertical tube, and its outer rim and the sealing of described inwall are fixed; This fin is spaced apart along this vertical tube length direction.

This programme has following improvement project:

In preferred embodiment, the sheet that described fin is annular, and perpendicular with the central axis of this vertical tube.

In preferred embodiment, described fin equidistantly distributes in this vertical tube.

In preferred embodiment, between described fin outer rim and vertical tube inwall, there is weld seam.

In preferred embodiment, also comprise layer protective layer, be covered in the outer wall of described outer tube.

The beneficial effect of this programme has:

1. by the inwall chamber at vertical tube, fin being set, thus the distortion of constraint vertical tube, and resistance to overturning and the rigidity of steel pipe are greatly improved.

2. outer tube has further been strengthened the ability of anti-deformation of vertical tube;

The accompanying drawing explanation

Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:

Fig. 1 is the schematic side view of the utility model embodiment mono-with section;

Fig. 2 is fin elevation embodiment illustrated in fig. 1;

Fig. 3 is the schematic side view of the utility model embodiment bis-with section;

Fig. 4 is embodiment illustrated in fig. 3 two front elevational schematic.

The specific embodiment

Embodiment mono-:

As depicted in figs. 1 and 2, the schematic diagram of the supporting steel pipe embodiment mono-of a kind of vertical enhancing of the utility model.It has a vertical tube 10, steel, prismatic straight tube form; Vertical tube 10 is that 6 meters its external diameters of long steel pipe are φ 50mm.

And fin 20, being fixed in the inwall of vertical tube 10, its outer rim and vertical tube 10 inwalls sealings are fixed; This fin 20 is spaced apart along these vertical tube 10 length directions.

The making flow process of the present embodiment is as follows:

1) material is prepared:

As Fig. 2, processing and fabricating fin 20(external diameter is 40mm, and internal diameter is 20mm, and thickness is 5mm); Processing and fabricating vertical tube 10 is for the steel plate of spiral welded, and width is 100mm, and thickness is 1.5mm, and length is depending on required wound steel pipe length, and the otch processing is carried out in two ends, guarantees to be rolled into after steel pipe in same cross section);

2) pipe crimping and welding:

The steel plate spiral is rolled into tubulose, and in bottom, Fig. 1 left end arranges first fin 20.And fin 20 is connected by side seam 21 with vertical tube 10 inwalls.Then adopt the helical coil seam spiral weld 11 to be fixed.Apart from the 292.5mm place, second fin 24 is set at distance first fin 20.And second fin 24 and vertical tube 10 inwalls are welded.All the other fins are analogized, and the equal interval 300mm of all the other fins.

Consider the spiral forming process of vertical tube 10, carry out the operation of side seam 21 and spiral weld 11 in the spiral pipe crimping.Guarantee that like this vertical tube 10 spirals are rolled into external diameter 43mm steel pipe, guarantee that all fins firmly are connected with the vertical tube inwall simultaneously.

Visible, by the inwall chamber at vertical tube 10, fin being set, thus the distortion of constraint vertical tube 10, resistance to overturning and the rigidity of steel pipe are greatly improved.

For the quality of the fin at the two ends that guarantee steel pipe, fin 20 indent 5mm, and with the steel pipe inner wall firm welding, except vertical weld 21, also have one section termination weld seam 22 to strengthen its firm degree.The centre of floor 20 has through hole 23, and tabular for annular flat, consumptive material is few, and radial force intensity is high.

Embodiment bis-:

As shown in Figure 3 and Figure 4, the schematic diagram of the utility model embodiment bis-.

Some similar embodiment one of the present embodiment structure, vertical tube 10, fin 20 and combination thereof, identical with embodiment mono-.Different, also there is an outer tube 30 in the present embodiment vertical tube 10 outsides, this outer tube 30 is to be fixed by the steel viscose glue, is socketed on the outer wall of vertical tube 10; The manufacturing process of this outer tube is as follows:

In the curling laminating of steel plate for outer wall of vertical tube 10, obtain the shape of outer tube 30; Its external diameter is 50mm; Simultaneously, this outer tube 30 has a vertical masonry joint 31, and this vertical masonry joint is carried out to weld job, and it is affixed, thereby promotes the quality of steel pipe.

Finally, the work such as top layer rust cleaning, slagging-off, polishing are carried out on the surface of right outer tube 30.And carry out the brushing operation of water pipe precaution layer 40 on surface.

To this whole this enhancing degree supporting steel pipe steel pipe, complete.It can give full play to the effect of the fin in the steel pipe inner wall chamber, reduces the deflection of steel pipe, thereby promotes the intensity of supporting steel pipe when supporting steel pipe, thereby realizes allowing the support system of template have higher vertical bearing capacity.

The above, it is only the utility model preferred embodiment, therefore can not limit according to this scope that the utility model is implemented, the equivalence of doing according to the utility model the scope of the claims and description changes and modifies, and all should still belong in the scope that the utility model contains.
