It is to be noted herein that various modifications and changes in form and detail with respect to the embodiments may be made without departing from the general inventive concept.

Fig. 1c and 3c schematically show two embodiments of a tube member 1, 1', respectively, which can be used for manufacturing beams and columns, respectively, of a building. The pipe elements 1, 1' according to the invention may, however, not be limited to the production of beams and columns, but may in principle also be used for the production of other elements in the civil engineering and construction sector, such as walls and the like. The pipe member 1, 1 'of the present invention may generally comprise a pipe 2, 2' and a reinforced concrete structure 3 arranged outside thereof. The pipes 2, 2' may be steel pipes. The tubes 2, 2' may also be made of other suitable materials without the need for welding.

As can be seen from fig. 1a, the cross beam tube 2 of the tube member 1 according to the first embodiment may be an elongated hollow profile. The cross member tube 2 can have two openings which are open at the end.

The cross-beam tube 2 can have a rectangular shape or a rectangular cross section. The dimensions of the rectangular cross-section may be, for example, width x height 150mm x 300 mm. In other embodiments, the crossbeam tubing 2 may have a circular cross-section or other polygonal cross-section.

The cross member tube 2 can be provided with through holes 4 at its two end sections 10, 11, which through holes 4 can be configured to be penetrated by screws 5 (for example screws or bolts) or rivets, by means of which the cross member tube 2 can be screwed or riveted to a connecting piece (not shown) which can be inserted or slipped with its two end sections into or onto the interior or exterior of the cross member tube 2 and the column tube 2' (see fig. 3a), respectively. In other embodiments, the cross-member tube 2 can be welded at its end to the column tube 2 'or connected to the column tube 2' in other mechanical connections, while the through-hole 4 can be unnecessary.

Fig. 1b shows a reinforcement cage 6 arranged outside the cross-beam tube 2. The rebar frame 6 can include longitudinal rebar 7 extending substantially parallel to the longitudinal direction of the beam tube 2 and transverse rebar 8 oriented perpendicular to the longitudinal rebar 7. The transverse reinforcement bars 8 may be fixed, e.g. welded, around the longitudinal reinforcement bars 7 to form a secure reinforcement frame 6.

In the illustrated embodiment, the rebar frame 6 can cover substantially exactly the entire length of the beam tube 2. Whereas in case the column tube 2' to be connected has a joint 9 (see fig. 3a), the reinforcement frame 6 may protrude beyond the two end sections 10, 11 of the beam tube 2 in the longitudinal direction, so that after connection with the joint 9, the reinforcement frame 6 may also cover the joint 9, so that concrete may also be introduced on the joint 9 to form the reinforced concrete structure 3.

The arrangement of the reinforcing cage 6 on the cross-beam pipes 2 can be done at the factory, whereby the amount of work at the construction site can be reduced.

Fig. 1b also shows a positioning device 12 (hereinafter "positioning device 12") fixed to the outer surface of the beam tube 2, the positioning device 12 being capable of positioning the longitudinal bars 7.

Referring to the perspective view of the positioning device 12 shown in fig. 2, the positioning device 12 may be configured as a hollow plate having a central opening 13, the size and shape of the central opening 13 may correspond to the size and shape of the outer surface of the cross beam tube 2, such that the positioning device 12 may be fitted over the outer surface of the cross beam tube 2 with the central opening 13. The fixing of the positioning device 12 to the outer surface of the cross-beam tube 2 can be performed by welding, but other suitable mechanical connection means, such as gluing, are also conceivable. After fixing, the faces of the hollow plates may be substantially perpendicular to the longitudinal direction of the cross-beam tube 2.

The positioning means 12 may be provided with through holes 14, each through hole 14 allowing one longitudinal reinforcement 7 to pass through. In the embodiment shown in fig. 2, the hollow plate is provided with four through-holes 14 on two opposite sides thereof, respectively, in succession. The number and arrangement of the through holes 14 on the positioning device 12 may vary according to actual needs. The axis of the through-opening 14 can be oriented perpendicular to the plate surface of the positioning device 12, whereby the longitudinal reinforcement 7 passing through the through-opening 14 can be oriented parallel to the longitudinal axis of the cross-member tube 2.

In the embodiment shown in fig. 2, the positioning device 12 may be a hollow plate of one-piece construction. When the positioning device 12 is attached to the cross-beam tube 2, the hollow plate can be fitted over a desired portion of the outer surface of the tube from one end of the tube and fixed.

In some embodiments, the positioning device 12 may also be a hollow plate constructed in multiple pieces, for example comprising two half-plates, which may be combined into one hollow plate. In some embodiments, the positioning device 12 may be any individual sheet, such as a rectangular sheet. These half plates or plates may not necessarily be placed on the cross beam tube 2, but may be moved directly from the side of the cross beam tube 2 and fixed to the outer surface of the cross beam tube 2.

In some embodiments, the positioning device 12 may be a block having a greater thickness with respect to the plate described above.

A plurality of positioning means 12 can be used in general to position the longitudinal bars 7 on their own, based on their long length. That is, the same longitudinal reinforcement 7 can be passed through two or more positioning devices 12, which positioning devices 12 can be arranged at a distance from each other in the longitudinal direction of the crossbeam tubing 2. In the embodiment shown in fig. 1b, two positioning devices 12 can be fixed to the longitudinal inside of the two end sections 10, 11 of the crossbeam tubing 2.

A tube member 1 for manufacturing a beam of a building, schematically shown in fig. 1c, can be seen, which may comprise a beam tube 2 and a reinforced concrete structure 3 arranged outside the beam tube 2. The reinforced concrete structure 3 may be formed by introducing concrete into the steel framework 6 shown in fig. 1 b.

As can be seen from fig. 1c, concrete can be introduced only between the two positioning devices 12 on the cross-beam tube 2, while no concrete can be introduced yet on the two end sections 10, 11 of the cross-beam tube 2. The introduction of concrete between the two positioning devices 12 can be done at the factory. This not only prevents the subsequent connection of the cross member tube 2 to the column tube 2' at the construction site with the end sections 10, 11 from being hindered by concrete, but also reduces the amount of work at the construction site. Whereas the introduction of concrete on the end sections 10, 11 can take place at the construction site after the connection with the pillar tube 2' has been completed.

In some embodiments, the cross beam tubes 2 can be subsequently welded to the column tubes 2' at the job site, so that concrete can be introduced at the factory over a greater length of the cross beam tubes 2, only at the locations at the two ends of the cross beam tubes 2 that are subsequently used for welding, without introducing concrete.

The thickness of the introduced concrete can be greater than the height of the positioning device 12 in the radial or transverse direction on the outer surface of the cross-beam tube 2, so that after the introduction of the concrete over the entire outer surface of the cross-beam tube 2, the positioning device 12 can be completely submerged by the concrete. If the locating means 12 were exposed to the exterior of the concrete, the aesthetics of the finished beam would be compromised and the locating means 12 would be susceptible to corrosion.

As can be seen from fig. 3a, the pillar tube 2' can also be an elongated hollow profile. The pillar tube 2' can have a rectangular shape or a rectangular cross section. The dimensions of the rectangular cross-section may be, for example, width x length 150mm x 300 mm. The pillar tube 2 'can have at least one opening which is open at the upper end side and via which concrete can be poured or introduced into the pillar tube 2', for example on the construction site.

The pillar tube 2' can have a rectangular shape or a rectangular cross section. In other embodiments, the pillar tube 2' may have a circular cross-section or other polygonal cross-section.

The column tube 2' may be provided with one or more joints 9 at approximately the middle for connecting the beam tube 2. The dimensions of the joint 9 may be, for example, width x height x length 150mm x 300mm x 450 mm. The joint 9 can also be considered as part of the pillar tube 2'. The joint 9 may also be formed from tubing. In the embodiment shown in the figures, four joints 9 are arranged one after the other at 90 ° angles on the four side walls of the pillar tube 2'. The number of joints 9 can vary with the number of subsequent total beam tubes 2 to be joined of the column tubes 2'. The joint 9 may extend perpendicular to the column tube 2 'and be fixed at one end to the column tube 2', which may be done at the factory by welding or other mechanical connection means. While the other end of the joint 9 may be open and may be used for connection with the beam tube 2 at the construction site, for example via the above mentioned connection. The joint 9 can be provided with a through-opening 4 for a screw 5 or rivet at its free end section in order to be fixed to the connecting piece.

The utility model discloses in, stand tubular product 2' and crossbeam tubular product 2 can be connected with any suitable mechanical connection mode. Thus, the joint 9 is not necessary for connection. For example, the joint 9 can be dispensed with when the cross-beam tube 2 is welded directly to the column tube 2'.

Fig. 3b shows a reinforcement cage 6 arranged on the outside of the column tube 2'. The placement of the rebar frame 6 can be done at the factory. The arrangement of the reinforcing steel frames 6 can be referred to the description of the reinforcing steel frames 6 on the cross beam pipe 2 in fig. 1 b. In the illustrated embodiment, the joint 9 may not be provided with the reinforcing frames 6, but may be covered with the reinforcing frames 6 extended from both ends of the cross-beam tube 2 after being connected to the cross-beam tube 2 at a construction site. Of course, it is also conceivable to arrange its own reinforcement cage 6 on the connection 9, as long as it does not interfere with the subsequent connection of the connection 9 to the cross-member tube 2.

The arrangement of the reinforcing bar frame 6 on the column pipe 2' can also be done at the factory, thereby reducing the amount of work at the construction site.

It can also be seen from fig. 3b that three of the above-mentioned positioning devices 12 are fixed on the upper half of the column tube 2 'at longitudinally spaced intervals, and two of the positioning devices 12 are fixed on the lower half of the column tube 2' at longitudinally spaced intervals to position the longitudinal reinforcing bars 7, but the number of the positioning devices 12 can be changed according to the actual situation.

For the positioning device 12 used for the pillar tube 2', reference is made to fig. 2 and the related description.

A tube member 1' for manufacturing a column, schematically shown in fig. 3c, can be seen, which may comprise a column tube 2' and a reinforced concrete structure 3 arranged outside the column tube 2 '. The joints 9 may be left without the reinforced concrete structure 3 for subsequent connection to the beam tube 2. Furthermore, the upper end section 15 of the pillar tube 2' can also be provided without the reinforced concrete structure 3 for subsequent connection to other pillar tubes.

As with the cross member 1, with the column member 1', the introduction of concrete into the reinforcing steel frame 6 can be done at the factory, whereby the amount of work at the construction site can be reduced. Whereas the introduction of concrete on the joint 9 and on the upper end section 15 can take place at the construction site after the connection has been completed.

As with the cross-member tube 2, the thickness of the concrete introduced into the column tube 2 'can be greater than the radial or transverse height of the positioning device 12 on the outer surface of the column tube 2'.

The tubing members 1, 1' shown in fig. 1c and 3c can be made at the factory. After they have been transported to the construction site, they are connected to each other in a suitable manner and concrete is poured into the interior of the pipes 2, 2' and outside the connection joints to form the beams and columns of the building.

Fig. 4a shows a first variant of the column tube 2' from fig. 3a in a perspective view. In a first variant, the pillar tube 2' can also have a rectangular shape or a rectangular cross section. Unlike the upright tube 2' shown in fig. 3a, the dimensions of the rectangular cross section can be, for example, 150mm by 600mm or 900mm wide by long. The column tube 2' can thus have two opposite, laterally larger or wider side walls 17, through which the reinforcement 16 can be passed at the same time and can be fixed, for example welded, to them. The rebar 16 may be oriented substantially perpendicular to the two sidewalls 17. The reinforcement 16 can be slightly higher in height than the upper surface of the joint 9 on the same side wall 17 and can be in transverse position between the two side walls 18 of the joint 9 and the two narrower side walls 19 of the pillar tube 2'. Subsequent to installation of the floor slab (not shown), the rebar 16 can assist in bearing the weight of the floor slab, as the floor slab can distribute its weight to both the beams and the rebar 16. In the illustrated embodiment, a respective reinforcement 16 can be arranged in a transverse position between the two side walls 18 and the two side walls 19, for example in the middle thereof. However, the number of the reinforcing bars 16 is not limited thereto, but may be determined according to the distance between the side walls 18 and the corresponding side walls 19.

In other embodiments, the rebar 16 may only pass through one sidewall 19, i.e., one end of the rebar 16 may be located inside the column tube 2'. The portion of the rebar 16 inside the column tube 2 'can be bent to more securely engage the concrete that is subsequently poured inside the column tube 2'.

Furthermore, referring to fig. 4b with the joint 9 hidden, inside the joint 9 there may be provided a reinforcement bar 20. The reinforcing bars 20 can be passed through both of the opposite side walls 17, 19 and can be fixed, e.g. welded, thereto. The rebar 20 can be oriented substantially perpendicular to the opposing sidewalls 17, 19. The reinforcement 20 may assist in the connection of the joint 9 to the column tube 2' in such a way that the reinforcement 20 may be coated and fixed by the concrete in the column tube 2' and the joint 9 after the concrete is poured inside both the column tube 2' and the joint 9. Thus, the joint 9 and the column tube 2 'can be connected not only by welding (i.e., one end of the joint 9 is welded directly to the side walls 17, 19 of the column tube 2'), but also by the reinforcing steel bar 20 and the concrete coated on the outside thereof.

The length of the reinforcement 20 exposed outside the column tube 2' may be less than the length of the joint 9, for example, one third of the length of the joint 9, i.e., not extending beyond the through hole 4, so as to prevent subsequent interference with connecting the joint 9 with the connecting member through the through hole 4.

In the illustrated embodiment, 3 reinforcing bars 20 are provided one above the other in each coupling 9, but other numbers and arrangements of reinforcing bars 20 are also contemplated.

In other embodiments, the rebar 20 may only pass through one side wall 17, 19, i.e., one end of the rebar 16 may be located inside the column tube 2'. The portion of the rebar 20 inside the column tube 2' can be bent to more securely engage the subsequently poured concrete.

Fig. 5a and 5b are second variants of the column tube 2' in fig. 3 a. Only the differences from the first modification will be described next, and the same parts will not be described again. In this second variant, two joints 9 can be provided on each side wall 17, 19 of the column tube 2' one above the other. The two joints 9 can be placed against each other and fixed, for example welded together. The column tube 2' can thus be connected with its two joints 9 to a respective cross-member tube 2 on each side wall 17, 19, thereby increasing the structural strength of the entire building. Other numbers and arrangements of the tabs 9 on each side wall 17, 19 are of course conceivable.

The utility model discloses in, the outside reinforced concrete structure 3's of tubular product component 1, 1' thickness can be in about 50mm-60 mm's within range, but is not limited to this, as long as can replace current fire prevention anticorrosive coating and play the fire prevention anticorrosion function can. The pipe members 1, 1' may also comprise an internally cast concrete or reinforced concrete structure (not shown). This internal casting may be done at the construction site, but in some embodiments it may also be done at the factory, which may be determined by the size and use of the pipe member itself.

The following summarily describes various possible advantages of the tubular component 1, 1' of the present invention, but without being limited thereto. In addition, each technical scheme of the utility model can only have some of the advantages; for any of these advantages, the various aspects of the present invention may have the advantage entirely or only to some extent.

Replace respectively in mill and job site in prior art to tubular product 2, 2 'outside application anticorrosive material and fire prevention material the utility model discloses in only need arrange reinforced concrete structure 3 to tubular product 2, 2' outside in the mill, reinforced concrete structure 3 can realize tubular product component 1, 1 ''s anticorrosive fire prevention function simultaneously, consequently can replace current fire prevention anticorrosive coating unexpectedly without problem. Furthermore, the arrangement of the reinforced concrete structure 3 outside the pipes 2, 2' is mostly completed in the factory, i.e. except for the connection node portion, and only concrete is easily applied to the outside of the connection node at the construction site. Therefore, the utility model discloses a tubular product component 1, 1' can reduce the work load of job site by a wide margin. In addition, compared with the existing fireproof anticorrosive coating, the reinforced concrete structure 3 is not easy to fall off from the outer surfaces of the pipes 1 and 1'. Finally, the arrangement of the reinforced concrete structure 3 has certain auxiliary reinforcement effect on the strength of the pipe members 1 and 1'.

Any of the elements, features and/or structural arrangements described herein may be combined in any suitable manner.

The particular embodiments disclosed above are illustrative only, as the invention may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein.
