Description

  • The present invention relates to a formwork system, in particular for tunneling, comprising at least one support arrangement for supporting a formwork comprising a plurality of formwork elements, which formwork system has at least one control for the support of the formwork elements and the concrete supply for the space to be concreted.
  • Such a formwork system is for example from the European patent 2 626 509 , the DE 28 26 623 A1 , the JP 2008 088696 A , the DE 100 40 777 A1 or the JP 2 932323 B2 known.
  • From the JP 2009 155819 A is a formwork system, in particular for tunneling, known, which comprises at least one support assembly for supporting at least one formwork element, which formwork system further comprises at least one concrete pump, a plurality of concrete feeds to the shuttering element and at least one controller, wherein on the formwork element at least two pressure sensors vertically arranged at different positions and are connected to the control of the formwork system, which pressure sensors are designed to measure the pressure acting on the formwork elements pressure at at least two different heights of the formwork element, and that the control is designed, the pump operation in response to the signal of the pressure sensors to control. A formwork system with the features of the preamble of claim 1 is from the post-published EP 3,168,413 A1 known.
  • It is an object of the invention to develop the generic formwork system such that individual circumstances in the creation of a concrete wall, in particular a concrete vault can be better taken into account.
  • This object is achieved by a formwork system with the features of claim 1. This object is further achieved by a method having the features of claim 13. Advantageous developments of the invention are the subject of the associated dependent claims. Advantageous developments of the invention are also disclosed in the description and in the drawings.
  • According to the invention, at least two pressure sensors are arranged vertically in different positions on the shuttering element and / or on the support arrangement and connected to the control of the shuttering system. The pressure sensors are designed to measure the pressure acting on the formwork elements due to the concrete loaded in the formwork at at least two different heights of the formwork element. The control system is designed to control the concrete infeeds individually depending on the signal from the pressure sensors. In this way it is possible to detect the concrete pressure acting at different points on the formwork element or preferably a plurality of formwork elements and the control can compare pressure values measured with nominal values by the pressure sensors and individually control the concrete feed so that the concrete pressure at the different points of the concrete Shuttering elements set specifications. In this way, a concrete wall, in particular a concrete vault with predetermined homogeneous material properties in the entire wall or vault area can be produced.
  • According to the invention, the support assembly has at least one hydraulic support beam for supporting the formwork element and the controller is designed to control the force of the support beam in dependence on the pressure measured in the pressure sensors. The pressure can thus be regulated not only on the individual concrete supply, but also on the Abstützdruck means of the support beams. In addition, the pressure sensors need not be provided in the formwork itself, but may be disposed on the force receiving elements of the formwork elements, e.g. at the points where the support structure statically supports the formwork element. In particular, if the entire formwork consists of several formwork elements, as is customary in tunneling, one is able to accurately detect the pressure acting on the individual formwork elements pressure on the support points of the formwork elements and the concrete feeders and / or the supporting force of the hydraulic support beams to control or regulate accordingly.
  • In a technically simple embodiment, the pressure sensor is arranged at the connection point between the support beams and the formwork element and / or the support arrangement. Such an arrangement is easy to implement, e.g. by per se known force transducer.
  • Preferably, several, in particular a plurality of pressure sensors distributed over the formwork element arranged. Preferably, the pressure sensors are arranged uniformly over the entire surface of the wall and thus over the surface of the formwork elements, if several are used. On In this way, a very good pressure distribution of the concrete can be detected on the formwork and possibly readjusted.
  • According to the invention, the formwork system includes at least one vibrator, and the controller is designed to control the vibrator as a function of the pressure measured in the pressure sensors. In this way, in areas where the concrete pressure acting on the formwork is too low, it can be achieved by shaking the concrete in the areas that the concrete pressure increases. The vibrating device can be arranged, for example, in connection with the formwork elements. However, external vibrators can also be provided in connection with the concrete feeders, which influence the viscosity of the supplied concrete.
  • Preferably, a plurality of vibrators are arranged at different locations of the formwork element and the controller is designed to control the vibrator individually as a function of the signals of the pressure sensors. In this way, a predetermined pressure profile of the concrete can be achieved on the formwork elements, which leads to desired homogeneous strength properties of the created concrete wall over the surface. Preferably, the vibrators are arranged evenly distributed over the formwork elements. In this way, a uniform compression can be achieved over the surface of the formwork.
  • In an advantageous embodiment of the invention, the controller is designed to control the concrete pump in response to the signals of the pressure sensors. Thus, e.g. Different concrete pumps can be provided for different concrete feeds and the delivery pressure of the concrete pump can be influenced by the pressure exerted by the concrete on the formwork element.
  • Preferably, the at least one concrete pump is connected via at least one distributor device with a plurality of concrete feeders. In this case, the controller is designed to control the distributor device as a function of the signals from the pressure sensors in order to achieve a homogeneous, predetermined pressure profile and thus desired material properties of the concrete wall created.
  • Preferably, the controller has a screen for displaying the formwork elements and the pressure values measured there. In this way, an operator can see which pressure values have been recorded on different parts of the formwork elements and can immediately detect whether the concrete has been supplied in a predetermined manner to the space behind the formwork elements. This is e.g. In the construction of a tunnel vault is extremely important because it must be ensured that the concrete at all points beyond the formwork elements consistently fills the gap between a tunnel wall and the formwork elements and thus is able to meet the required strength properties of the tunnel arch.
  • In an advantageous development of the formwork system according to the invention this has at least four formwork elements, which are supported by at least four support beams against the support assembly. Such an arrangement is thus useful for a tunnel vault, the four formwork elements more or less the form the upper semicircle of the tunnel arch. Preferably, the four formwork elements are curved for this purpose and form a vaulted area for a tunnel arch.
  • Since a tunnel formwork is usually very long, the formwork system according to the invention preferably has a plurality of horizontally arranged one behind the other support arrangements with their own formwork elements. The controller is then designed to control the pressurization of the formwork elements of the individual support arrangements individually as a function of the pressure values of the pressure sensors. In this way, a homogeneous tunnel formwork over a greater length can be produced in one operation, over the area a very good homogeneity of the concrete wall is achieved.
  • In a method according to the invention which uses the formwork system according to the invention, a concrete wall is constructed in which the pressure acting on the formwork element pressure is determined at different locations by means of pressure sensors and the at least one concrete pump and / or the concrete feed is controlled in response to the signals of the pressure sensors or be. In this way, care can be taken by the individual control of the concrete feed or the concrete pump (s) that a uniform pressure profile or a predetermined pressure profile over the surface of the formwork elements is achieved, which brings tunnel vault with required strength properties with it.
  • By the signals of the pressure sensors and vibrators or distribution devices can be controlled between the concrete feeders so as to fill the concrete supply to the individual points between a tunnel wall and the formwork elements as evenly and homogeneously.
  • In addition to the signals of the pressure sensors, the signals of other sensors such as e.g. Temperature sensors, optical sensors or chemical sensors for the control of the support assembly, the individual concrete feeders and the vibrators are used.
  • By means of the invention, the properties of the concrete filled into the formwork can thus be ascertained, evaluated and utilized for the control of the concrete feeders, support arrangement and vibrating devices. For better operation, the controller preferably has a screen, which represents the formwork system area, as well as a Betonfüllanzeige for the different areas of the formwork elements. The measured forces are preferably via software evaluated and displayed digitally and visually. Preferably, the controller has an interface for controlling other components, such as a vibrator, as well as for loading the data on external media or on an additional PC. Due to the detected signals of the pressure sensors, the compression control can take place automatically beyond the formwork elements.
  • By means of the invention, a counter-check is made to the static calculation of the shuttering process. The safety for the formwork system as well as for the persons who operate the formwork system is considerably increased. Homogeneous and better tunnel walls are achieved, which optimizes concreting processes. The invention achieves the creation of standards compliant concrete walls and vaults. The outputs of the controller can also be used for safety systems, if voltage overshoots or pressure peaks at individual points of the formwork elements should be detected. The invention contributes to the quality assurance of the building.
  • An essential aspect of the invention is that on the targeted control of the concrete pump and / or the concrete supply and / or the at least one vibrating the compression processes of the concrete beyond the formwork elements can be controlled specifically and individually, thus desired material properties of the finished concrete wall or achieve the finished concrete vault.
  • It is obvious to a person skilled in the art that the individual components of the invention can be provided simply or multiply, or they can also be designed as an integrated unit or distributed at several locations. The controller may include multiple computers distributed throughout the length of the tunnel. Similarly, a tunnel formwork system usually has a plurality of formwork elements, e.g. four formwork elements distributed over the vault sector and three to six support assemblies in a row, each with four formwork elements, so that in total the system preferably has between ten and fifty formwork elements.
  • The following expressions are used synonymously: vibrator - vibrator; Pressure transducer - pressure sensor; Temperature sensor - temperature sensor

  • Fig. 1 shows a tunnel formwork system 10 according to the invention, which is located in a broken tunnel vault 12. The tunnel formwork system 10 according to the invention comprises a support arrangement 14 for supporting a formwork 15, which consists of articulated interconnected formwork elements 16-26 whose outer side is slightly curved and the tunnel vault 12 assigns. Between the outside of the formwork elements 16-26 and the tunnel vault or the Tunneln 12 a void 28 is formed, which is filled with concrete 13. The support assembly 14 includes hydraulic support beams 30 to support the formwork members 16-26 with a predetermined pressure against the filled concrete 13. The formwork system 10 according to the invention is controlled by a central controller 32, which preferably has a screen 34 for displaying the formwork system of the associated measured values. The formwork system 10 further comprises a concrete feed pump 36 with a manifold 38 and concrete pipes 40, which run to individual concrete feeders 42, which in the Fig. 2 and 5 are shown in more detail. The central controller 32 is connected to pressure sensors 44, as well as with temperature sensors or Ultrasonic transducer 46, which detect both the pressure acting on the formwork elements 16-26 pressure due to the filled concrete and the temperature of the concrete, so as to give the central control 32 feedback, on the one hand on the density and the degree of filling of the concrete in the space between the Outside of the formwork elements 16-26 and the tunnel wall 12 as well as the chemical reaction in the setting of the concrete, which is associated with a heat generation or a change in density. By detecting the temperature or the density, it is thus easy to determine how far the setting reaction precedes. Optionally, for this purpose, the controller is also connected to a concrete analysis device 48, which evaluates, for example, the setting behavior of a concrete sample and possibly its strength in order to conclude conclusions about the strength and the concrete between the formwork elements 16-26 and the tunnel wall can.
  • The controller 32 is of course connected to the concrete pump 36, as well as to the distribution device 38. Furthermore, the controller preferably has a USB port 50, as well as a wireless port 52, such as Wi-Fi® or Bluetooth®. By the in Fig. 1 shown detection of the temperature density and pressure conditions, it is the formwork system possible to control the individual concrete feeders 42 and / or the hydraulic supports 30 such that on the one hand the concrete flows in a desired manner and is compressed, as well as the predetermined pressure conditions correspond to to ensure a desired quality of concrete formwork.
  • Fig. 3 also shows the formwork system 10 Fig. 1 , here the connection of the central controller 32 with vibrators 54 is shown. The central controller 32 can individually control the individual vibrators 54 as a function of the sensor values in order to effect a targeted compaction of the concrete in the different regions of the tunnel wall 12, in order to ensure as homogeneous a concrete quality as possible over the entire tunnel wall 12.
  • Fig. 4 shows the connection of the central controller 32 with mirror difference sensors 56, which may be, for example, pressure sensors, optical sensors, thermal sensors, ultrasonic sensors or chemical sensors. These mirror-difference sensors 56 are uniformly distributed over the outside of the formwork elements 16-26. In this way, it is easily possible, a different level h1, h2 of the concrete 13 on the two sides of the To detect the tunnel wall and to ensure by individual control of the concrete feeders 42 and vibrator 54 that the filling level is even on both sides or is compensated.
  • Fig. 5 shows the connection of the central controller 32 with the individual concrete feeders 42. By controlling the concrete pump 36 and the manifold 38 and other unillustrated distribution elements, such as shut-off valves, it is possible to supply the concrete specifically to the individual concrete feeders 42 so as to be homogeneous To reach concrete feed. Ideally, the supply of concrete via the relatively evenly distributed concrete feeders 42 in conjunction with a corresponding operation of the vibrators 54 made Fig. 3 ,
  • Fig. 6 shows the connection of the central controller 32 with pressure transducers 58, which extend evenly over the upper portion of the tunnel formwork, ie on the upper formwork elements 20-24, so that it can be verified by this arrangement of pressure sensors 58, whether the concrete 13 between the tunnel wall 12 and the outside of the formwork elements 16-26 is actually completely filled, which is reflected in corresponding pressure values. These pressure sensors can also be designed as hydraulic cylinders that deliver a controllable support pressure for the formwork elements. These pressure sensors 58 can therefore also be used for pressure control of the support pressure of the formwork elements 20 to 24.
  • Finally shows Fig. 7 a plan view of the formwork system according to the invention according to the Fig. 1-6 , but in isolation, ie not in operating position in a tunnel vault 12.
  • Fig. 8 shows a formwork system 60 for the production of straight walls. The formwork system 60 includes a support assembly 62, a central controller 32 with a display 34, a concrete pump 36, possibly a manifold, not shown, optionally a concrete analyzer 48 and a number of planar formwork members 72-78 arranged one above the other and side by side are so as to form a wall of desired size. The controller is connected via a first control line 80 with concrete feeders 82. Via a second control line 84, the controller 32 is connected to a temperature sensor or ultrasonic sensor 86. Via a third control line 88 and a fourth control line 90, the controller 32 is connected to pressure transducers 92. To this The central controller 32 detects the pressure conditions as well as the temperature conditions on the concrete 13 side facing the formwork 71, which is formed from the individual shuttering elements 72-78.
  • Fig. 9 shows the formwork system 60 Fig. 8 in supervision. It should be noted here that in the figures identical or functionally identical parts are provided with identical reference numerals.
