Description
Technical Field
The invention relates to a method for manufacturing at least one section of a supporting structure of an escalator or a moving walkway, designed in particular as an arrangement for a continuously circulating step belt of an escalator or a continuously circulating pallet belt of a moving walkway. Such a section includes a first stringer, a second stringer, and connecting struts, wherein each connecting strut has a first end and a second end.
Background
Escalator support structures are known, for example, from document WO 2011/073708 a1 or from document CN 203903754U. In many escalators or moving walkways, the support structure consisting of L-shaped or U-shaped steel beams as stringers and connecting struts is welded together in a truss structure. Such a support structure has a high load capacity, which is necessary in particular to ensure safe operation of the escalator or moving walkway, even at full load of maximum load capacity. The disadvantage here is the heavy dead weight of the support structure itself. Furthermore, the construction of such a support structure for escalators or moving walkways is complicated and generally involves a large labour expenditure. Moreover, low manufacturing tolerances in the dimensions of the various components of the support structure (in particular in the connection struts) need to be observed, which further increases the costs of manufacturing such support structures.
Disclosure of Invention
Against this background, the problem addressed by the present invention is to improve a method for manufacturing at least one section of a supporting structure of an escalator or moving walkway. Advantageously, the improvement should allow for more economical manufacture of such support structures or sections thereof. Furthermore, such a support structure should advantageously achieve a lighter self-weight for substantially the same load capacity.
In order to solve this problem, a method for manufacturing at least one section of an escalator or moving walkway support structure, and a moving walkway or escalator support structure as claimed in the independent claims of the present application are proposed. Further advantageous features and embodiments of the invention are described in the dependent claims and in the description.
The proposed solution envisages a method for manufacturing at least one section of a support structure of an escalator or moving walkway, which support structure is designed as an arrangement of continuous-loop step belts, in particular for escalators, or continuous-loop pallet belts of moving walkways, wherein such a section comprises a first longitudinal beam, a second longitudinal beam and connecting struts, and wherein the connecting struts each have a first end and a second end. A first connection point is defined on the first stringer at which the first end of the connecting strut is connectable to the first stringer. Furthermore, a first receiving point is formed at the first connecting point for receiving the first end of the connecting strut. The receiving point can be embodied as a receiving opening, which is drilled in the stringer or cut out of the stringer, for example. In particular, the receiving points can also be constructed as recesses or indentations in the respective stringers.
Furthermore, the method according to the invention provides for the respective first end of the connecting strut to be inserted into the receiving point. That is, the receiving points are advantageously designed to correspond to the shape and size of the respective ends of the connecting strut, so that the connecting strut can be inserted into the receiving points, in particular by being pushed in, advantageously with little play. Advantageously, the receiving point and the respective end of the connecting strut are adapted to one another such that the connecting strut of the stringer inserted into the receiving point is retained in that receiving point (in particular in the case of connecting struts which need not be additionally supported).
Furthermore, the method according to the invention provides that the connecting struts are each fastened to the first longitudinal beam. The fastening of the connecting strut to the first longitudinal member is advantageously simplified because the connecting strut is inserted before into the first receiving point of the first longitudinal member. Furthermore, the length differences between the individual connecting struts, in particular between several millimeters and several centimeters between the individual connecting struts (which may be caused in particular by manufacturing tolerances), are homogenized by varying the insertion depth when the connecting struts are introduced into the receiving points. It is therefore proposed in particular that the shorter connecting struts are inserted more shallowly into the receiving points than the longer connecting struts.
The fixing of the connecting struts to the respective longitudinal girders may in particular be effected by friction locking, force locking, form-fitting and/or integrally bonded connection of the respective connecting struts to the respective longitudinal girders. In particular, it is proposed that the connecting struts are already fixed by insertion into the receiving points.
According to a particularly advantageous embodiment of the method, it is proposed that the fixing of the respective connecting strut to the respective longitudinal beam is done by welding the connecting strut to the longitudinal beam. Advantageously, the connecting struts are welded to the longitudinal girders at the locations where the connecting struts project from the receiving points, i.e. in particular in the region of the receiving points.
An advantageous modification of the method according to the invention proposes to determine a second connection point on the second stringer, at which second connection point the second end of the connecting strut is connected to the second stringer. Furthermore, it is proposed to form a second receiving point, in particular a second receiving opening, at the second connecting point for receiving the second end of the second strut. The respective second end of the connecting strut is then inserted into the second receiving point. After this, the connecting struts are each fixed to the second longitudinal beam. If the connecting struts project from the first longitudinal beam by different distances such that the connecting struts have different heights when measured from the first longitudinal beam, these distances can advantageously be homogenized by introducing the connecting struts into the second receiving points at different depths. In particular, it is proposed that the first longitudinal beam and the second longitudinal beam are oriented parallel to each other. Advantageously, this modification of the method further simplifies the manufacture of the section of the moving walkway or escalator support structure.
Specifically, it is proposed to use vertical connecting struts and diagonal connecting struts as the connecting struts. The vertical connecting struts are oriented perpendicular to the first stringer and perpendicular to the second stringer and are secured to the first stringer and the second stringer, and the diagonal connecting struts are oriented diagonally between and secured to the first stringer and the second stringer. This advantageously creates a truss structure with particularly good stability at the sections. In particular, it is proposed that the vertical connecting struts and the diagonal connecting struts are arranged between the first longitudinal beam and the second longitudinal beam such that the vertical connecting struts and the diagonal connecting struts form a zigzag structure. Other advantageous embodiments provide that the vertical connecting strut and the diagonal connecting strut are inserted together into a corresponding receiving point, which is therefore designed to receive one end of the vertical connecting strut and one end of the diagonal connecting strut. Advantageously, the respective receiving point is designed such that it is designed for receiving at least two connecting struts. The receiving points can be designed in particular as receiving points with different contours in specific regions, so that connecting struts with different cross sections can be inserted together, preferably with a substantially exact fit, into the receiving points provided for this purpose.
When using vertical connecting struts and diagonal connecting struts, it is furthermore particularly proposed to define a third connecting point on the respective vertical connecting strut, wherein the first end of the respective diagonal connecting strut can additionally be connected to the vertical connecting strut at this third connecting point. A third receiving point, in particular a third receiving opening, is then formed at the third connecting point of the vertical connecting strut for receiving the first end of the diagonal connecting strut. The respective first ends of the diagonal connecting struts are additionally inserted into these third receiving points of the vertical connecting struts. In particular, it is proposed to first insert a vertical connecting strut with a third receiving point into the corresponding receiving point of the longitudinal beam. This is preferably done in that the respective receiving point of the longitudinal beam together with the respective receiving point of the vertical connecting strut forms a receiving point for the end of the diagonal connecting strut. Advantageously, the ends of the diagonal connecting struts are then inserted into the formed receiving points. After this, the diagonal connecting struts are preferably fixed, preferably in the region of the formed receiving points, to the vertical connecting struts and to the longitudinal girders.
When using vertical connecting struts and diagonal connecting struts as connecting struts, a further advantageous modification of the method according to the invention proposes to determine a fourth connection point on the respective vertical connecting strut at which the second end of the respective diagonal connecting strut can additionally be connected to the vertical connecting strut. A fourth receiving point, in particular a fourth receiving opening, is then formed at the fourth connecting point of the vertical connecting strut for receiving the second end of the diagonal connecting strut and the second end of the diagonal connecting strut is additionally inserted into the fourth receiving point of the vertical connecting strut. In this way, the stability of the section to be manufactured is advantageously further increased. Furthermore, the section is thus configured symmetrically with respect to the first longitudinal beam and symmetrically with respect to the second longitudinal beam. Advantageously, this further reduces the possibility of errors being generated during the manufacture of the section.
As a further advantageous modification of the method according to the invention, it is proposed that the third receiving point and/or the fourth receiving point of the vertical connecting strut are/is constructed such that they each form, together with one of the receiving points of the stringers, a common receiving point for receiving the respective end of the diagonal connecting strut. Advantageously, the construction of the sections of the support structure is made easier in this way. In addition, the stability or load capacity of the support structure assembled from such sections can be further enhanced in this way.
In particular, a method is therefore proposed in which a first receiving point is inserted into a first longitudinal beam and a second receiving point is inserted into a second longitudinal beam. Furthermore, a third receiving point and a fourth receiving point are inserted at the ends of the vertical connecting struts, respectively. After that, the end of the vertical connecting strut at which the third receiving point is located is inserted into the first receiving point of the first longitudinal beam each time. Advantageously, this is achieved in that the vertical connecting strut is oriented perpendicular to the first longitudinal beam and the first receiving point of the first longitudinal beam forms a right-angle receiving point together with the third receiving point of the vertical connecting strut. Preferably, the vertical connecting strut is then fixed, preferably by welding, to the first longitudinal beam. The first ends of the diagonal connecting struts are then each inserted into a right-angled receiving point formed by the first vertical connecting strut and the first longitudinal beam. Advantageously, the diagonal connecting strut is oriented such that the second end of the diagonal connecting strut is inserted into the fourth receiving point of the further vertical connecting strut. Preferably, the diagonal connecting struts are then connected, preferably by welding, to the vertical connecting struts and to the first longitudinal girders. After that, a second longitudinal beam with a second receiving point is placed on the second end of the vertical connecting strut with a fourth receiving point, wherein the second ends of the diagonal connecting struts are each inserted into the fourth receiving point, so that the second ends of the connecting struts are inserted into the second receiving point. Advantageously, the second stringer is then oriented parallel to the first stringer. The diagonal connecting struts and the vertical connecting struts are then connected, in particular welded, in particular by welding, to the second longitudinal member in the region of the second receiving point of the second longitudinal member.
According to an advantageous embodiment of the method, it is thus proposed that the diagonal connecting struts and the vertical connecting struts are fixed together, in particular by welding. In this way, stability and load capacity are advantageously further increased.
A further advantageous embodiment of the invention proposes to determine a fifth connection point on the first longitudinal beam of the first section and on the first longitudinal beam of the second section, respectively. At these fifth connection points, the first end of the further connecting struts, in particular the vertical connecting struts and/or the diagonal connecting struts, can be connected to the first longitudinal girder of the first section and the second end can be connected to the first longitudinal girder of the second section. For this purpose, after the fifth connection points have been determined, first of all fifth receiving points, in particular fifth receiving openings, are formed at these fifth connection points of the first longitudinal beam of the first section for receiving the first ends of the further connecting struts. Furthermore, a fifth receiving point, in particular a fifth receiving opening, is formed at the fifth connecting point of the first longitudinal beam of the second section, for example by using a suitable cutting method or chip-removing method, for receiving the second end of a further connecting strut. In a further method step of this advantageous embodiment of the method according to the invention, the respective first end of a further connecting strut is inserted into the built-up fifth receiving point of the first longitudinal beam of the first section. Furthermore, the respective second ends of these connecting struts are inserted into the fifth receiving point of the first longitudinal beam of the second section. Furthermore, it is proposed in particular to fasten the connecting struts to the first longitudinal beam of the first section and to fasten the connecting struts to the first longitudinal beam of the second section, preferably in the region of the respective receiving point.
As a further particularly advantageous step of the method according to the invention, it is proposed that the distance between the stringers of a section, in particular the distance between the first and second stringers of a section, is adjusted by the insertion depth of the connecting struts located between these stringers into the respective receiving points. The receiving point can be designed in particular such that it is a bore hole which passes completely through the receiving opening of the respective longitudinal beam, in particular of the respective longitudinal beam. It is therefore advantageous for the respective ends of the respective connecting struts to be inserted into the respective receiving points according to the required length in order to achieve the desired distance between the stringers of the segments. Preferably, the stringers are oriented parallel to each other. It is therefore advantageous that the distance between the stringers of a section can be adjusted independently of the length tolerance of the connecting struts to be arranged between the stringers, at least within certain limit values. In this way, advantageously, the manufacture is more economical, since greater length tolerances, in particular length tolerances of a few millimetres (for example length tolerances up to 20 millimetres), are allowed in the manufacture of the connecting strut. This further results in a reduction of scrap during manufacturing.
According to a further particularly advantageous embodiment of the invention, it is proposed to use hollow profiles, in particular square tubes, as first longitudinal beams and/or second longitudinal beams and/or connecting struts. It is particularly preferred to use square tubes as the first longitudinal beam, as the second longitudinal beam and as the connecting struts. However, a variant of the invention is proposed, in which a metal profile, in particular a profile steel, is used as the first longitudinal member and/or the second longitudinal member and/or the connecting struts, so that the receiving point is always built up on a surface section of the metal profile. Such metal profiles or profiled bars are in particular familiar profiles for steel beams, for example in particular T-profiles, L-profiles or U-profiles. On the contrary, however, the use of hollow profiles, such as in particular square tubes, has weight advantages. For the same choice of material and the same stability, it is therefore advantageously possible to manufacture corresponding square tubes instead of metal profiles such as L-profiles or U-profiles with a smaller material thickness and thus a reduced weight.
Advantageously, by constructing the receiving points in the stringers and introducing the respective ends of the connecting struts into the receiving points according to the invention, it is advantageously ensured that the length of the square tube can have large tolerances even when the first and second stringers of the section are oriented parallel to one another. The different lengths of the connecting struts are advantageously compensated for by appropriately varying the insertion depth in the receiving point. In particular when using square pipes as stringers, it is proposed to insert an accommodation opening as an accommodation point into one wall of the square pipe. Advantageously, the receiving opening is inserted such that its opening contour is adapted to the end of the connecting strut to be inserted, in particular such that the respective end of the connecting strut can be inserted into the receiving point. In an advantageous variant embodiment of the invention in which the receiving points are also inserted into the vertical connecting struts, it is likewise proposed in particular to insert the receiving points, in particular as receiving openings, or as indentations starting at the respective ends of the square tubes, or as receiving points of cutouts starting at the respective ends of the square tubes into the walls of the respective square tubes.
In particular, it is also proposed to complete the fixing of the connecting struts by welding. Advantageously, this fixing by welding is facilitated by the prior introduction or insertion of the connecting struts to the respective receiving points. In particular, it is proposed that the sections are produced such that the longitudinal beams form a self-supporting plug connection with the connecting struts inserted into the receiving points, which is already held without welding. Advantageously, the welding is performed along the respective housing points into which the respective connecting struts are inserted. The gap between the receiving point and the connecting strut inserted into the receiving point is preferably no greater than a few millimeters, particularly preferably no greater than 2 millimeters.
Advantageously, the moving walkway or escalator support structure according to the invention has a modular design consisting of a plurality of sections. Advantageously, first, sections can be manufactured that are easy to transport. Advantageously, these sections can then be brought to the location where the moving walkway or escalator is to be erected and assembled there into a corresponding support structure. In the case of escalators, it is proposed in particular that the respective end sections (i.e. the entrance and exit of the escalator) are formed by sections which are each formed by at least two support structure sides. It is also advantageous if the support structure connecting the ends (i.e. the middle piece of the support structure) is made up of a section which is formed by at least two support structure sides.
Unless explicitly required, it is stated that the disclosed method steps need not be performed in the order of presentation. Conversely, the steps of the proposed method can be permuted in a technically meaningful manner (i.e. in a manner which is technically possible). Thus, for example, it goes without saying that the determination of the first connecting point is always done before the first receiving point is built up, whereas the determination of the second connecting point on the second longitudinal beam can of course take place before the determination of the first connecting point on the first longitudinal beam.
Furthermore, it is specified that the use of the ordinal numbers (for example "first accommodation point" and "second accommodation point") for the elements relating to the support structure is used to distinguish the corresponding elements and does not constitute any order. These serial numbers do not constitute any fixed number. Thus, the first longitudinal beam may for example comprise several first accommodation points and also several fifth accommodation points. In particular, the first stringer may have a first receiving point and a fifth receiving point, and the stringer need not have a second receiving point and/or a third receiving point and/or a fourth receiving point.
The moving walkway or escalator support structure proposed further as a solution to the aforementioned problems, in addition to the method according to the invention, is in particular a moving walkway or escalator support structure manufactured according to the method of the invention. In particular, the moving walkway or escalator support structure according to the invention comprises longitudinal beams and connecting struts. The stringers and connecting struts are connected together such that they form a support structure floor and support structure sides. The support structure floor is advantageously connected to the support structure side. The moving walkway support structure according to the invention or the escalator support structure according to the invention comprises at least one section comprising a first longitudinal beam, a second longitudinal beam and connecting struts each having a first end and a second end. The first longitudinal beam has first receiving points, wherein the first ends of the connecting struts are each inserted into the first receiving points. The connecting strut is fixed to the first longitudinal beam. The receiving point can be embodied here as a receiving opening, in particular a bore or a cutout or a recess. The support structure is particularly intended to accommodate a component of a moving walkway or escalator, such as particularly a continuously circulating step belt or a continuously circulating pallet belt. Furthermore, each support structure is specifically designed for placing a balustrade with a handrail. The receiving point of the stringer can be embodied as a receiving opening, in particular a bore or a cutout or a recess. In particular, it is proposed that the receiving points are advantageously configured to correspond to the shape and size of the respective end of the connecting strut, so that the connecting strut is advantageously inserted into the connecting strut with little play, in particular advantageously as a plug connection. Advantageously, in particular in the case of connecting struts which are not additionally supported or do not need to be additionally supported, the respective receiving point and the respective end of the connecting strut are adapted to one another in such a way that the connecting strut inserted into the receiving point is held by the longitudinal beam at this receiving point.
A particularly advantageous modification of the moving walkway or escalator support structure according to the invention provides that the second longitudinal beam has a second receiving point into which the respective second end of the connecting strut is inserted. The connecting strut is secured to the second beam. In particular, it is provided that the connecting struts are welded to the respective longitudinal girders at the respective receiving points. Furthermore, as a variant, it is proposed to fix the connecting struts by friction locking, force locking and/or form-fitting connection, in particular screw connection. Furthermore, it is proposed in particular that the first longitudinal beam of the section and the second longitudinal beam of the section are oriented parallel to one another.
As a particularly advantageous embodiment of the invention, a vertical connecting strut and a diagonal connecting strut are provided as connecting struts, wherein the vertical connecting strut is oriented perpendicularly to the first longitudinal beam and perpendicularly to the second longitudinal beam and is fastened to the first longitudinal beam and the second longitudinal beam, and the diagonal connecting strut is oriented diagonally between and fastened to the first longitudinal beam and the second longitudinal beam. In particular, the arrangement of the stringers and connecting struts is such that a truss structure is formed. This provides particularly good stability on such sections. In particular, it is proposed that the vertical connecting struts and the diagonal connecting struts are arranged between the first longitudinal beam and the second longitudinal beam such that the vertical connecting struts and the diagonal connecting struts form a zigzag structure. A further advantageous embodiment provides that the vertical connecting strut and the diagonal connecting strut are inserted together into a corresponding receiving point, wherein such a receiving point is thereby designed for receiving one end of the vertical connecting strut and one end of the diagonal connecting strut.
An advantageous modification of the moving walkway or escalator support structure according to the invention proposes that the first number of vertical connecting struts have a third accommodation point, wherein the first ends of the first number of diagonal connecting struts additionally insert into the third accommodation point of the vertical connecting strut. Preferably, the first number of vertical connecting struts is equal to the first number of diagonal connecting struts. In this way, the stability of the support structure is advantageously further enhanced.
Furthermore, the second number of vertical connecting struts of the advantageously moving walkway or escalator support structure has a fourth receiving point, wherein the second ends of the second number of diagonal connecting struts additionally insert into the fourth receiving point of the vertical connecting strut. In particular, it is proposed that the second number of vertical connecting struts is equal to the second number of diagonal connecting struts. Further examples suggest that the first number of vertical connecting struts is equal to the second number of vertical connecting rods.
Advantageously, the third receiving point and/or the fourth receiving point of the vertical connecting strut are/is designed such that they each form, together with one of the receiving points of the longitudinal beams, a common receiving point into which the respective end of the diagonal connecting strut is inserted. Advantageously, this further enhances the stability or load carrying capacity of the support structure assembled from such segments.
In particular, a moving walkway or escalator support structure is proposed, in which a first accommodation point is inserted into a first longitudinal beam and a second accommodation point is inserted into a second longitudinal beam. Furthermore, respective third and fourth accommodation points are inserted at the ends of the vertical connecting struts. The end of the vertical connecting strut at which the corresponding third receiving point is located is inserted into the first receiving point of the first longitudinal beam. Advantageously, the vertical connecting strut is oriented perpendicular to the first longitudinal beam, while the first receiving point of the first longitudinal beam and the third receiving point of the vertical connecting strut always form a right-angled receiving point. Furthermore, the first end of the diagonal connecting strut is always inserted into the right-angled receiving point formed by the first vertical connecting strut and the first longitudinal beam. The diagonal connecting strut is oriented such that the second end of the diagonal connecting strut is inserted into a further receiving point formed by the second receiving point of the second longitudinal beam and a fourth receiving point of a further vertical connecting strut. Preferably, the diagonal connecting struts are always connected, preferably by welding, to the respective vertical connecting struts and to the respective longitudinal girders.
A further particularly advantageous embodiment of the moving walkway or escalator support structure according to the invention comprises a plurality of sections, wherein the first longitudinal beam of the first section forming at least part of the side of the first support structure and the first longitudinal beam of the second section forming at least part of the side of the second support structure have a respective fifth accommodation point. The respective first end of the further connecting strut is inserted into a fifth receiving point of the first longitudinal beam of the first section. Furthermore, the respective second ends of these connecting struts are inserted into the fifth receiving point of the first longitudinal beam of the second section. Furthermore, it is provided that the connecting strut is fixed to the first longitudinal beam of the first section and the connecting strut is fixed to the first longitudinal beam of the second section to form a third section constituting at least a part of the support structure floor. It is therefore advantageous that the moving walkway or escalator support structure according to the invention has a modular design.
According to a particularly advantageous supporting structure of the moving walkway or escalator, the longitudinal beams and/or the connecting struts are hollow beams, in particular square tubes. In this way, the support structure advantageously has a high stability. Such a support structure also advantageously has less dead weight for the same stability when compared to the use of profiled steel (e.g., L-beams or U-beams).

Detailed Description
Fig. 1 shows an exemplary embodiment of a section 1 of an escalator structure manufactured by a method according to the invention. The section 1 comprises a first longitudinal beam 2, a second longitudinal beam 3 and connecting struts 4, 5. The segment 1 has as connecting struts vertical connecting struts 4 and diagonal connecting struts 5. The vertical connecting struts 4 are oriented perpendicular to the first longitudinal beam 2 and perpendicular to the second longitudinal beam 3. The diagonal connecting strut 5 is oriented diagonally between the first longitudinal beam 2 and the second longitudinal beam 3. Preferably, hollow profiles are used as longitudinal beams and connecting struts.
In the exemplary embodiment shown in fig. 1, the first 2 and second 3 stringers are square tubes each having four equally wide sides and a first perimeter, the cross-sectional surface of the stringer is therefore substantially square, for example, a square tube of this type for the stringer has the dimensions 60 × 60 × 4, i.e. 60mm (mm: mm) width per side and 4mm thickness per side in the exemplary embodiment 2290mm length.
For example, such a square tube for the vertical connecting strut 4 may have dimensions of 30 × 30 × 2, i.e., 30mm in width for each side and 2mm in thickness for each side.
A flat steel profile is used as diagonal connection strut 5 in this exemplary embodiment, for example, this flat steel profile for a diagonal connection strut can have the dimensions 10 × 60 × 1450, i.e. the thickness of this flat steel profile is 10mm, the width of the side of this flat steel profile is 60mm and the length of this flat steel profile is 1450 mm.
In order to produce a section 1, which can in particular form a section of an escalator support structure side, it is proposed to define a first connecting point on the first longitudinal beam 2 and a second connecting point on the second longitudinal beam 3. At a first connecting point of the first longitudinal beam 2, a first end 6 of the connecting strut 4, 5 is later connected to the first longitudinal beam 2. At a second connection point of the second longitudinal beam 3, the second end 7 of the connecting strut 4, 5 is later connected to the second longitudinal beam 3.
After the connection points have been determined, first receiving points 8, 8' are formed at the first connection points. Second receiving points 9, 9' are formed at the second connecting points.
In the exemplary embodiment shown in fig. 1, the receiving opening is inserted as a first receiving point 8, 8 'into the first longitudinal beam 2 at the determined first connecting point and as a second receiving point 9, 9' into the second longitudinal beam 3 at the determined second connecting point by means of a cutting process. It can therefore be said that the first connecting point marks the position in the first longitudinal beam 2 at which the first receiving point 8, 8' should be constructed. It can therefore be said that the second connection point marks the position in the second longitudinal beam 3 where the second receiving point 9, 9' should be built.
The receiving points 8, 8 ', 9' are configured to receive the ends 6, 7 of the connecting struts 4, 5. In the exemplary embodiment shown in fig. 1, the configuration of the receiving points 8, 8 ', 9', in particular the form of the opening contour of the receiving points 8, 8 ', 9', is done in particular depending on whether a single connecting strut or two connecting struts together are to be inserted into the respective receiving point. Thus, in the exemplary embodiment shown in fig. 1, it is provided that the first end 6 of only one vertical connecting strut 4 is to be inserted into the receiving point 8', which can be seen at the bottom on the left side of fig. 1. This receiving point 8 'is therefore a receiving point with a substantially square profile, wherein the opening area is only slightly larger than the cross-sectional area of the vertical connecting strut 4, so that the vertical connecting strut 4 has been retained by the first longitudinal beam 2 as a result of the insertion of the first receiving point 8'. Conversely, the further first receiving point 8 in the first longitudinal beam 2 is designed such that the first end 6 of the vertical connecting strut can be inserted therein and additionally the first end 6 of the diagonal connecting strut 5 can also be inserted therein. These first receiving points 8 are therefore constructed such that, like the receiving points 8', they have a receiving opening of substantially square profile for receiving one end 6 of the vertical connecting strut 4 and subsequently a rectangular receiving opening of substantially rectangular profile for receiving one end 6 of the diagonal connecting strut 5. The configuration of the first receiving point 8 can be seen in particular in fig. 2, in which fig. 2 the cut-out 25 in fig. 1 is enlarged. Analogously to the first receiving points 8, 8 ', second receiving points 9, 9' are formed in the second longitudinal beam 3.
Furthermore, a third connection point is defined on the vertical connecting strut 4 into which the receiving point 8 should be inserted. At these third connection points, which are determined at the respective first ends 6 of the vertical connecting struts 4, the first ends 6 of the diagonal connecting struts 5 will additionally be connected to the respective vertical connecting struts 4. For this purpose, a third receiving point is formed at the third connecting point. As shown in fig. 2 or fig. 3 and 4 (which respectively show a sectional illustration of the parts indicated in fig. 2), the third accommodation point 10 in this example is inserted as a cut-out having a substantially rectangular contour into one side of the respective first end 6 of the vertical connecting strut 4.
A fourth connection point is thus defined on the vertical connecting strut 4 into which the receiving point 9 should be inserted. The fourth connection points are respectively defined at the opposite sides of the vertical connecting strut 4 to the sides having the third connection points. At these fourth connection points, which are determined to be at the respective second ends 7 of the vertical connecting struts 4, the second ends 7 of the diagonal connecting struts 5 are additionally connected to the respective vertical connecting struts 4, respectively, according to the method described above. Analogously to the construction of the third receiving point 10, a fourth receiving point is constructed for this purpose at the second end 7 of the respective vertical connecting strut 4.
After the first and second longitudinal beams 2, 3 and the vertical connecting strut 4 have been provided with corresponding receiving points, the first end 6 of the vertical connecting strut 4 is inserted into the first receiving point 8, 8'. The vertical connecting struts 4 are held in the first receiving points 8, 8' by friction locking. The depth to which the vertical connecting struts 4 are inserted into the receiving points 8, 8 'determines how long the vertical connecting struts 4 protrude from the receiving points 8, 8'. Furthermore, those vertical connecting struts 4 which are inserted into the first receiving point 8 are inserted into the receiving points 8 in such a way that the third receiving points 10 of these vertical connecting struts 4 form together with the first receiving point 8 a common receiving point which is substantially at right angles. The first end 6 of the diagonal connecting strut 5 is then inserted into the receiving point formed by the first receiving point 8 and the third receiving point 10.
The insertion of the diagonal connecting struts 5 is done in such a way that the second ends 7 of the diagonal connecting struts 5 are inserted into the fourth receiving points 11 of the vertical connecting struts 4, respectively. By means of the insertion depth, it is possible to adjust how long the diagonal connecting struts 5 protrude from the respective receiving points. At least the first receiving point 8 and the third receiving point 10 are designed in such a way that the inserted diagonal connecting strut 5 is held by friction.
After the first end 6 of the vertical connecting strut 4 has been inserted into the first receiving point 8, 8 'and the first end 6 of the diagonal connecting strut 5 has been inserted into the first receiving point 8 and the third receiving point 10 and the second end 7 has been inserted into the fourth receiving point 11, the vertical connecting strut 4 and the second end 7 of the diagonal connecting strut 5 are inserted into the second receiving point 9, 9' of the second longitudinal beam 3. The second longitudinal beam 3 is oriented parallel to the first longitudinal beam 2. The second receiving point 9, 9' is designed in such a way that the second longitudinal beam 3 is frictionally held at the vertical connecting strut 4 and the diagonal connecting strut 5.
After the stringers 2, 3 and the connecting struts 4, 5 have been suitably oriented, the connecting struts 4, 5 are additionally fixed to the stringers 2, 3 in such a way that the vertical connecting struts 4 and the diagonal connecting struts 5 are welded to the first stringer 2 and the second stringer 3. Furthermore, the diagonal connecting struts 5 are welded to the vertical connecting struts 4. In the exemplary embodiments described above, the welding is done along the receiving points 8, 8 ', 9', 10, 11. The dimensions indicated at the beginning for the stringers 2, 3 and the connecting struts 4, 5 are described in the figures, which gives, for example, an outer spacing of 1080mm between the first stringer 2 and the second stringer 3.
In particular, with longer stringers 2, 3 and a greater number of connecting struts 4, 5, it is proposed to design the section 1 shown in fig. 1 to be correspondingly larger. Neither connecting strut 4, 5 needs to be fastened to the longitudinal beam 2, 3 in a strictly zigzag arrangement (as shown in the exemplary embodiment shown in fig. 1). Nevertheless, such a zigzag arrangement still constitutes a particularly advantageous embodiment. Further advantageous embodiments of the invention propose that the section 1 shown in fig. 1 is expanded by being placed along the sides and connected (preferably by welding) to further sections to form the support structure sides. In this case, the section 1 constitutes a section of the side of such a support structure.
It is furthermore provided that, starting from two sections 1 manufactured according to the invention (as shown in the example in fig. 1), these sections are connected by means of further connecting struts to form a larger section of the supporting structure of the escalator or moving walkway. For this purpose, a fifth connection point is respectively defined on the first longitudinal beam 2 of the first section 1 and on the first longitudinal beam of the second section (not shown in fig. 1 to 4). At these fifth connecting points, the first end of the later further connecting strut will be connected to the first longitudinal beam 2 of the first section 1 and the second end thereof will be connected to the first longitudinal beam of the second section. For this purpose, a fifth receiving point 12 (indicated by a dashed line in fig. 1) is first formed at the determined fifth connecting point of the first longitudinal beam 2 of the first section 1. Preferably, these fifth receiving points 12, like the first receiving points 8, 8' in the first stringer 2, are inserted into the first stringer as receiving openings by means of a cutting method, so that they are adapted to receive the first ends of the further connecting struts. In a corresponding manner, a fifth connection point is built up at the fifth connection point of the first longitudinal beam of the second section to accommodate the second end of the further connecting strut. The first ends of the connecting struts are then each inserted into a fifth receiving point 12 of the first longitudinal beam 2 of the first section 1. The connecting strut, which is inserted with its first end into the receiving point 12, is held by the receiving point by means of a friction lock. The second ends of the connecting struts are then each inserted into a fifth receiving point of the first longitudinal beam of the second section.
After the first longitudinal beam 2 of the first section 1 and the first longitudinal beam of the second section have been oriented parallel to one another, the connecting struts are fixed by welding at the first longitudinal beam 2 of the first section 1 and at the second longitudinal beam of the second section. In this way, the third section is thus constructed according to one embodiment of the method of the invention. The first section 1 and the second section 2 here form the moving walkway or escalator structure side, while the third section forms the moving walkway or escalator support structure floor.
Fig. 5 shows an exemplary embodiment of an escalator support structure 20 according to the present invention. The exemplary embodiment of the escalator support structure 20 shown in fig. 5 includes a lower end member 27, an intermediate member 26, and an upper end member 28. By means of the end pieces 27, 28, the escalator support structure 20 is arranged at the floor of the building 24 by means of the end supports 23. Further, the escalator structure 20 comprises stringers 2, 3 and connecting struts 4, 5 connected together to form a support structure floor 21 and support structure sides 22. The support structure side portions 22 of the end pieces 27, 28 and the middle piece 26 are manufactured according to one variant of the method of the invention. That is, the escalator support structure has multiple sections that are connected (preferably by welding) together to form the support structure.
The section, for example the support structure side 22 of the middle part 26, comprises a first longitudinal beam 2, a second longitudinal beam 3 as well as a vertical connecting strut 4 and a diagonal connecting strut 5. As already discussed, for example, with reference to fig. 1, the connecting struts 4, 5 each have a first end and a second end, and the connecting struts 4, 5 are inserted into the receiving points of the stringers via the first and second ends and are fixed to the respective stringers. The different arrangements of the vertical connecting struts 4 and the diagonal connecting struts 5 for the support structure sides 22 should be construed as arrangements or order of arrangement of the connecting struts may vary without departing from the scope of the invention.
In particular, it may be provided that the support structure floor 21 may be manufactured as a third section from two support structures 22 as a first section and a second section, as already explained. However, as shown in fig. 5, the vertical connecting struts 4 can also be placed conversely between the support structure sides 22 as support structure floor 21 and for example welded to the connecting struts 4, 5 of the support structure sides 22.
The exemplary embodiments shown in the figures and described in connection with the figures are intended to illustrate and not to limit the invention.
