Definitions
- the system is substantially based on or supported by a set of metal double T beams, which will be referred to as lightweight and heavyweight, of the type made up of the joining of a double C-section profile having bent flanges joined by their respective webs, which are parallel, opposing and spaced from one another by reinforcing cross-members which are transversely welded equidistantly spaced from one another.
- a set of metal double T beams which will be referred to as lightweight and heavyweight, of the type made up of the joining of a double C-section profile having bent flanges joined by their respective webs, which are parallel, opposing and spaced from one another by reinforcing cross-members which are transversely welded equidistantly spaced from one another.
- beams are combined with a series of accessories carrying out different functions of building, trussing, shoring, scaffolding, and for other purposes in any type of construction or building processes, whether public or private, providing simple solutions for very diverse and complicated building cases, consisting of metal beams made of galvanized sheet or sheet treated against oxidation due to their broadest outdoor function, which beams preferably must be highly stress resistant in any working direction and they must also be resistant to the loads they are to withstand, which in this case are average and heavy loads, and preferably, the lighter and more lightweight the more recommendable they are.
- the aforementioned beams are doubly lightened in the web of each side and at the head in transverse coincidence with the separations between webs.
- it is the same profile inverted, opposing at their webs and joined by welded reinforcing cross-members, with a special profile and arranged with proportional equidistance to the length of the beam.
- the calculation of the dimensions, of the section of the sheets, of the arrangement and diameter of the lightening holes and of the assembly holes will depend on a series of advantages with respect to weight, use of material and use of the beam constituting a novelty in the structural systems of this type which have been used or known until now as the most current and relevant systems.
- At least two systems can be pointed out in relation to this type of beams for forming truss structures, one corresponding to the British company SGB FORMWORK, known as Mk II Soldier System, and another one corresponding to the company RMD IBERICA, S.A., known as Super Slim or Slimshor.
- Both of them are made up of double T beams formed by two C-shaped profiles with bent flanges, joined at their respective webs by means of reinforcing cross-members.
- the first ones have diamond-shaped openworkings with rounded vertexes in their webs with a very small equidistance and broad span having intercalated blade-shaped ribs parallel to the sides of each openworking and having in the center thereof one or two boreholes, depending on the section, in this case aligned according to the vertical axis.
- the second ones have aligned, circular-shaped openworkings, with somewhat less of a span in relation to the section which is about 40% and having circumscribed boreholes arranged in an orthogonal formation with respect to the central openworking.
- the web has reinforcements in the area including the openworking and the boreholes. This arrangement of boreholes is made on two first end openworkings and alternating every three openworkings in the rest.
- connectors which at most consist of eight connections, making it unfeasible to bend the horizontal shaft of the truss of the structure, which logically has certain resistance conditions.
- the invention is based on Spanish patent ES 2244253 A1 , belonging to the same applicant as the present and of the inventor Mr. Julio Barba Castro, relating to a: SYSTEM OF LIGHTWEIGHT TRUSS STRUCTURES FOR FORMING, SHORING, SCAFFOLDING OR THE LIKE, dated 19/06/2002 , anticipating the mentioned document D1 and in which the lightweight beam of the set of beams of the current invention is substantially the same as this one with advantageous changes in the positioning, location and measurements of the different elements forming this structure and in the development of a related beam, which is a heavy beam or is a beam for withstanding heavy loads, which is itself reinforced with other identical beams joined to one another, having the same basic structure and especially the equivalent means for the joints or connections in the trussing of the structures to one another and with others in different combinations for the purposes laid out in the title of these patents.
- EP 1 566 504 A1 discloses a system of truss structures according to the preamble of claim 1.
- the invention attempts to rationalize and make use of the working moments of said beams so as to adjust them such that, when combined to one another, it is not necessary to use excessively large beams in relation to the average, high and very high stress and loads they must withstand in this case; for that purpose two beams having different sections and spans but which are directly complementary to one another have been provided so that they can be combined or connected using virtually ambivalent parts and means; which beams are very specific and lightened such that according to the calculation performed they effectively carry out the working task they must carry out.
- the new development offered by the beams of the invention in both their versions are defined by a series of lightening holes arranged with the same strategy as in the aforementioned earlier patent of the same inventor for the coupling of a group of additional complements making it a single known beam which, with smaller dimensions and thicknesses in relation to existing beams, better defines their resistant capabilities as the lightening holes are understood as being merely functional and not primarily esthetic or commercial.
- the object of the present invention is a system of truss structures according to claim 1.
- the object of the invention is to allow their use in any sector requiring structural solutions of the type comprised in the title of the invention, no matter how complex they may be, not necessarily having to manufacture said structures for exclusive use in this job.
- they are especially intended for trussing formwork boards, for forming scaffolding structures, for shoring frameworks or others such as timbering, stiffeners and the like in which, reinforcing means such as simple braces are additionally provided for spacing between beams having little span or combined with jacks having tensioning members for reinforcement between beams with a spacing having a large span.
- the lightweight and heavyweight beams according to the invention share the same lightening holes with the same size (60 mm) in the webs of each of them, there being one centered lightening hole in the first case and axially aligned lightening holes in the second case, preferably three in number in relation to the width of the beam.
- the difference is minimal according to very different stress load functions and in a complementary order they act as a very versatile and resistant purlin which, since they share the same distances between axes in the head end plates at the beginning and end of the beam as those distances between the webs and flanges or side soles for either beam, can be combined together perfectly and accessories can be interchanged which in this case would become common to the two beams.
- the invention consists of developing two hollow double T beams having purlins made up of 5 and 6 mm thick C-shaped profiles respectively, with bent flanges acting as soles and planar webs separated by corresponding equidistantly spaced reinforcing cross-members and having two versions of different widths, the smallest one being 47.62% smaller, which will be referred to as the lightweight beam and, the larger beam will be referred to as the heavyweight beam. Both beams are of the same height, i.e.
- Both the lightweight and heavyweight beams also have the same developments and equivalent distribution and size in relation to their means of lightening their complementary and anchoring means, and they are completely identical in relation to the fixing holes, even in relation to the orthogonal arrangement around the nodes of the reinforcing cross-members.
- the lightening holes are equal circular vertical openworkings of 60 mm in diameter in the webs of the beams, but they vary in number, and the fixing or anchoring holes are preferably equal to 18 mm in diameter and the lightening and anchoring holes of the end plates are also equal in both beams, 50 mm in diameter, and the fixing holes are preferably 20 mm for the heavyweight beam and 18 mm for the lightweight beam, the distribution of the first holes being formed by pairs which are equidistant between centers at the same distance of 110 mm, and intercalating sets of pairs which may vary in number depending on the length of the beam, bearing a set of four circumscribed fixing holes distributed in orthogonal position in relation to the lightening holes in both beams, to the nodes of the cross-members and of the lightening holes of the head end plates which also have an equal equidistant spacing between centers, as previously mentioned, of 110 mm in both cases, and they define a regular square perimeter around the lightening hole.
- the aforementioned head end plates of the beams according to the invention are rectangular and adapted to the transversal section of the heavyweight and lightweight beams respectively. Each one has its respective portions but they have an equal section in both cases, and the plate of the heavyweight beam is preferably 18 mm thick and the plate of the lightweight beam is preferably 15 mm thick, the distribution of the lightening holes and fixing boreholes being the same, the one with the largest diameter being located in the center and the other four with the smaller diameter orthogonally circumscribing the center one, there being an equal distance between centers (110 mm), with the particularity that the plate of the heavyweight beam has preferably three axially and horizontally aligned lightening holes and the plate of the lightweight beam has preferably one in the center.
- Said heavyweight and lightweight beams are arranged according to the invention in different lengths, preferably in five lengths, four of them being comprised between 2500 mm and 500 mm, decreasing by 500 mm; a fifth one being half the length of the latter (250 mm) and final sixth one being 44% of the previous one, being a part for compensating measurements when double connectors are alternated with single connectors in the same structure since they have the same length as the separation between axes of the fixing holes (110 mm).
- the aforementioned known connectors are essential elements for carrying out any structure; they are defined by plates in a hexahedral arrangement in a simple case, with just as many connections for the beams and for the plates in the parallelepiped arrangement of double connectors, for a larger number of connections for the beams forming two joined bodies equivalent to two single connectors in which the head end plates have the same lightening holes with a larger diameter and the fixing with a smaller diameter in the same equidistant arrangement as in the case discussed in the background of the patent belonging to the applicant of this invention.
- the connectors internally incorporate on the lightening holes having the smaller diameter respective fixing nuts for fixing the different joining members of the corresponding beams. These nuts allow the direct threading of the joining members by turning them in either direction, according to their position, to secure the screwing.
- the invention also has adjustable jacks with a typical function of shoring of the beam structure, made up of the corresponding screw assembled in a support formed by a threaded cylinder resting on a rectangular plate with fixing boreholes and triangular reinforcing stiffeners for the cylinder and an end with an anchor for bracing the beams.
- Such anchor is assembled in the lightening holes with the larger diameter of the beams by means of a corresponding pin, threading and complementary side means. Therefore screw with a left-hand threading in one end and a right-hand threading on the other end allows installing the beam by opening or closing the diagonal by simply turning said beam.
- Another complementary means is also used with a typical function of bracing the beam structure for fixing a rod to the beam which is adjusted against the inner diameter of two parallel lightening holes with a larger diameter, and it is fastened by means of respective nuts above and below the wedge.
- the jack is completed with a diagonal reinforcement for the rod and a diagonal reinforcement for the jack.
- the former is a semi-cylindrical half-round part with a perpendicular borehole and milled sides in its perimeter and the other one is a disc-shaped part with a central concentric deep-drawing and a circular borehole also concentric to the deep-drawing.
- the former is arranged between parallel lightening holes with a larger diameter with the milling locked against its edges and being fastened by means of nuts, one above the wedge and another below it.
- the second one is assembled in said lightening holes on either side, used as a fastener for the pin and nuts passing through the anchor of the jack.
- the heavyweight beam is indicated with (1) and the lightweight beam with (1a), which beams have through lightening holes in their respective webs with a large diameter of 60 mm (23 - 23'), being located in two rows, paired and vertically opposing in the heavyweight beam (1), and in a single row and centered (34 - 34'), also vertically opposing and 60 mm in the lightweight beam (1a).
- Each one is surrounded by smaller holes (10) of 18 mm of diameter in both beams, preferably in an orthogonal arrangement, equidistant and on both coordinate axes, at a distance (x) ( Figure 7 ) of preferably 110 mm between axes, while the welding nodes of the reinforcing cross-members (29) are aligned with the longitudinal axes in the same orthogonal arrangement and housed in the spaces (20) and (30) of each beam and set in the in the slots (28) ( Figures 7 and 8 ) of the web of both beams, and they also have fixing holes (10) at a distance (x) between axes, also of 110 mm, the thicknesses of the sheet of beams (1) being 6 mm and the arrangement and housed in the spaces (20) and (30) of each beam and set in the in the slots (28) ( Figures 7 and 8 ) of the web of both beams, and they also have fixing holes (10) at a distance (x) between axes, also of 110 mm, the thicknesses of
- Such flanges (27) are also provided with corresponding fixing holes ( 100 ), with the same diameter of 18 mm and at the same distance (x) at 110 mm between axes.
- the reinforcing cross-members (29) are assembled in the openings or separations (20-30) of the beams (1) and (1a), being fastened in three slots (28) cut into each of the webs with 49 mm in length, with spaces of 77 mm, by means of 48 mm long embossments (28'), spaced transversely at distances of 78 mm, in which the embossments (28') are fixed by means of welding, forming nodes around which there are sets of fixing holes ( 101 ) in an equal orthogonal arrangement and separation (x) as the previous ones at 110 mm between axes and which, according to the length of the beams (1- 1a), are distributed as follows (shown in Figure 1a ):
- Beams (1) and (1a) are closed at their ends by means of the corresponding head plates (24) and (31) respectively, Figures 3 and 4 and Figures 9 and 10 also respectively.
- Said plates (24) have axially aligned central lightening holes (26) and plate (31) has a central lightening hole (35) equal to the previous ones, all having a large diameter of 50 mm and in the contour of these fixing holes there are other holes with a smaller diameter (25-36), respectively, in the same orthogonal distribution as in the webs of profiles (21-22) and (32-33) of the beams (1) and (1a) such that the distance (x) between the centers of the holes (25-36) is the same in the two plates (24) and (31) and that the diameter of the holes (25) in plate (24) is 20 mm and the diameter of the holes (36) in plates (31) is 18 mm.
- the vertical section is equal in both plates (24 and 31) and equivalent to the width (r) of the beams (1) and height of the beams (1a). Therefore, the horizontal section of said beams (1) and (1a) varies, such that the latter is (y) 47.62% (200 mm) of the first one, i.e. the first beam (1) is twice as long + 20 mm (w) (420 mm).
- the thickness of the longer plate (24) is 18 mm and the thickness of the shorter plate (31) is 15 mm.
