Definitions
- the invention relates to a self-advancing support and sliding formwork for introducing an in-situ concrete lining of the type specified in the preamble of claim 1.
- Such support and sliding formwork can usually be used optionally in continuous, discontinuous or batch-wise concreting operations.
- formworks which consist of elements which can be folded or lowered and which rest on a ' supporting frame ' which can be moved along the longitudinal axis of the tunnel * .
- This formwork has the disadvantage that the associated formwork and set-up work is very time-consuming and costly.
- tunnel or tunnel construction or chimney construction require concrete formwork that can slide forward continuously or discontinuously on the one hand and that on the other hand can be converted to a batching concreting operation without any effort, e.g. if special reinforcements are to be installed in sections of the track that are subject to particularly high pressure or if recesses for niches, cross passages etc. are to be made.
- the object of the invention is to propose a self-advancing support and sliding formwork of the type specified in the preamble of claim 1, which, in conjunction with a free choice between a continuous, discontinuous or batch-wise concreting operation, drives the formwork in all three operating modes under the usual ones operating conditions occurring without any external support of the tensile or compressive forces is required for this, ie to create formwork that is self-advancing in all three operating modes.

- Fig. 6 shows an embodiment in which the
- Sliding formwork is formed in two parts in the form of a progressive expansion formwork and a similar subsequent support formwork;
- Fig. 7 is a cross-sectional view of a
- Fig. 8 is a schematic cross-sectional view of another embodiment of the hydraulic support of the formwork elements.
- a formwork body 10 is provided which is divided into a plurality of formwork segment groups 12, 22 and 32 lying axially parallel alongside one another in the circumferential direction.
- Each formwork segment 14 comprises a formwork element in the form of a formwork sheet 16, which is attached to the concrete and which can be inflated via hydraulically actuated transmission elements, which in the embodiment shown in FIG. 5 are hoses 50, is connected to a supporting substructure in the form of a longitudinal beam 18.
- the longitudinal beams 18 in turn are supported on support frames, of which the frontmost support frame 40 is shown in FIGS. 1 and 2, while further support frames 42 and 44 are shown in FIGS. 3, 4 and 6.
- the supporting and sliding formwork also includes an end formwork 34 which closes the front of an annular space which between the outer wall of the building or an outer formwork attached there , e.g. an outer .Concrete shell around the formwork body 10 is formed.
- the front formwork 34 is supported on the support frame 40, which is the foremost in the forward direction, by means of a hydraulically variable support guide 70.
- the individual formwork segments 14 are longitudinally displaceable relative to their adjacent formwork segments, while each formwork sheet 16 is variable in height with respect to its longitudinal beam 18.
- Sealing elements which are arranged along the longitudinal sides of the formwork sheets 16 between them, seal the above-mentioned annular space, i.e. they prevent concrete from escaping into the interior of the formwork body 16.
- the formwork sheet 16 and the associated longitudinal beam 18 of each formwork segment 14 are coupled to one another in the longitudinal direction so as not to be displaceable, while the hydraulic transmission elements in the form of the expandable hoses 50 for each formwork segment
- ER S ATZBLATT 14 are arranged between the formwork sheet 16 and the longitudinal beam 18.
- formwork segments 14 are combined to form different formwork segment groups 12, 22, 32.
- As many formwork segment groups 12, 22, 32 are provided for each sliding formwork as there are support frames 40, 42, 44.
- Each of the formwork segment groups 12, 22, 32 is firmly connected to another of the support frames 40, 42, 44 and is slidably mounted on the remaining support frame.
- each formwork segment group forming approximately 1/3 of the formwork skin in the embodiment shown.
- Some of the factors influencing this choice are the expected frictional forces in the respective areas of the formwork skin and / or the frictional forces that are effective on the formwork segments when these are to be advanced from the rest position.
- HE 6 shows a two-part design of a sliding formwork in the form of a progressive expansion formwork 2 and a similar supporting formwork 4.
- the formwork segments 14 of the two formworks 2 and 4 are arranged in alignment in the longitudinal direction.
- five groups of expandable hoses 50 are provided which are arranged parallel to one another and which are accommodated on the back of the associated formwork sheet 16 or 16a in associated chambers which are separated by separating webs 20 or 20a are limited.
- the separating webs 20 and 20a engage between and around the hoses 50.
- the outer dividing webs 20a are of elongated design and engage as lateral holding elements around the associated longitudinal member 18, so that they cause a transverse displacement between the formwork sheet 16 or 16a and the longitudinal member 18 prevent.
- the groups of inflatable tubes 50 can themselves be subdivided into individual chambers.
- a hydraulic control arrangement 60 is provided, by means of which a preset pressure value can optionally be maintained in each of the hoses 50 or hose chambers.
- the hydraulic arrangement 60 comprises a hydraulic pump and for each hose 50 or chamber an associated pressure relief valve, the Opening pressure is adjustable,
- the formwork sheet 16a is biased by tension springs in a position radially retracted relative to the formwork skin. Furthermore, the formwork sheet 16a has an elastically flexible cover 17 on its side facing the formwork skin.
- an arbitrary support frame in FIG. 4a the middle support frame 42 with the help of the presses 52 arranged between the support frames 40, 42, 44 including the formwork segment group firmly connected to this support frame 42 (which is not shown in detail in the drawing) is) advanced by a preselected step length x.
- the inflatable hoses 50 of the assigned formwork segment group are switched to transport, i.e. the pressure prevailing in the inflatable hoses is kept at a preselected pressure value by means of assigned pressure limiting valves and the hydraulic pump provided in the hydraulic arrangement 60.
- the formwork sheets 16 and 16a adjacent to the concrete wall can react to changes in the course of the surface of the concrete wall, i.e.
- the rear support frame 44 with its associated formwork segment group and then the front support frame 40 with its associated formwork segment group are each reduced by
- the formwork is supported on an unspecified roadway by hydraulic support presses, which are not specified.
- the " pressure in these support presses is controlled so that unevenness in the roadway, as well as convergences or divergences of the roadway in relation to the longitudinal axis of the formwork are compensated by the corresponding support cylinders being retracted or extended accordingly.
- the front formwork 34 is sealed along the circumference of the annular space to be concreted by seals that are not shown. Furthermore, the front formwork 34 is guided by a pressure piston of the hydraulic support guide 70 which is longitudinally displaceable in a pressure cylinder. Since the support guide 70 is firmly attached to the foremost support frame 40 in the advancing direction, the relative position of the front formwork 34 can be kept guided in relation to the annular closed foremost cross section of the formwork skin, regardless of whether all formwork segment groups together form the front ring surface or one or more of the formwork segment groups have been advanced. In addition, the hydraulic guidance of the front formwork 34 allows the formwork body 10 with its formwork skin to be advanced within certain limits independently of the " introduction of the concrete into the annular space.
- the shuttering plates 16 can each Schalungssegmentgrup 'pe 12, 22 are subtracted 32 prior to their further advance of the concrete wall to prevent a frictional engagement.
- the forward movement of the entire support and sliding formwork can thus take place in partial sections, the individual formwork segments or formwork segment groups being pressed against the concrete wall again after advancing in order to be able to absorb the reaction forces which occur when the following formwork segment groups are advanced.
- the two-part design of the supporting and sliding formwork shown in FIG. 6 is suitable in such cases when the concrete section to be stripped does not yet have the required load-bearing capacity.
- the post-supporting formwork takes on the task of supporting until the required load-bearing capacity is reached in the assigned concrete section.
- the post-supporting formwork 4 is basically constructed in the same way as the advancing expansion formwork 2.
- the formwork segment groups of the expansion formwork 2 and the support formwork 4 are of course selected from one another such that they are aligned one behind the other and can advance in the longitudinal direction, so that no disadvantage
- the support formwork segments are advantageously removed from the concrete wall before the forward movement.
- they are equipped with tension springs in the embodiment shown in FIG. 7, which prestress the formwork sheet 16a on the associated longitudinal beam 18.
- the inflatable hoses 50 are switched to a lower pressure value or without pressure, the formwork sheets 16a are pulled back from the concrete wall by the tension springs.
- the formwork sheet 16a has a cover 17 made of elastically resilient material on its surface facing the concrete wall, which ensures that the supporting formwork segment supports the entire surface thereof even in uneven areas of the concrete.
- the supporting formwork segments with a smaller width than the actual formwork segments or, given a corresponding existing load-bearing capacity of the concrete, only certain areas, e.g. to support the ridge areas.
- Fig. 8 shows a further embodiment for hydraulic support of the formwork element.
- a flexible hose 55 is arranged between the opposite surfaces of the longitudinal beam 18 and the formwork sheet 16.
- the chamber delimited in this way is closed off along the longitudinal sides by longitudinal side webs 20a which are attached to the formwork sheet 16.
- the flexible hose 55 has only a sealing function.
- the pressure of the hydraulic fluid is taken up by the walls 16, 18 and 20a enclosing the chamber or the cavity.
