Abstract

A method and a device for controlling the delivery rate of a concrete pump for filling a formwork arrangement with a pumpable filling compound as a function of curing-relevant material and environmental parameters, after which the installed filling compound sets within the formwork arrangement, comprising the following steps: determining a permissible climbing speed for filling the formwork arrangement with the filling compound on the basis of the material and ambient parameters, measuring the static filling compound pressure acting on the formwork arrangement during filling, and calculating the permissible delivery rate of the concrete pump as a function of the determined permissible rate of ascent and the measured static filling compound pressure at the formwork arrangement.

First claim

The invention claimed is:

1. A method for controlling the delivery rate of a concrete pump for filling a formwork arrangement with a pumpable filling compound as a function of curing-relevant material and environmental parameters, afterwhich the installed filling compound sets within the formwork arrangement comprising:
determining a permissible rate of ascent for filling the formwork arrangement with the filling compound on the basis of the material and ambient parameters,
measuring the static filling compound pressure acting on the formwork arrangement during filling,
calculating the permissible delivery rate of the concrete pump as a function of the determined permissible rate of ascent and the measured static filling compound pressure at the formwork arrangement.

2. The method according to claim 1 , wherein the material and environment parameters are selected from a parameter group comprising: filling compound formulation data, formwork dimension data, or outside temperature.

3. The method according to claim 2 , wherein the filling compound formulation is provided on the basis of available construction planning information of a construction planning database.

4. The method according to claim 3 , wherein a material-specific temporal curing characteristic is or can be derived from the filling compound formulation data.

5. The method according to claim 2 , wherein the information resulting from the formwork dimension data is provided on the basis of available construction planning information from the construction planning database.

6. The method according to claim 5 , wherein the information includes a section-by-section concreting height, concreting area, and wall thickness.

7. The method according to claim 2 , wherein the outdoor temperature is measured via a temperature sensor at a construction site or is provided by a public weather database.

8. The method according to claim 1 , wherein the measurement of the static filling compound pressure acting on the formwork arrangement during filling is carried out by a measuring sensor system arranged in the region of the formwork arrangement.

9. A device for carrying out the method according to claim 1 , comprising:
an analysis unit for determining a permissible rate of ascent for filling the formwork arrangement with the filling compound on the basis of the material and ambient parameters,
a measuring sensor system for measuring the static filling compound pressure acting on the formwork arrangement during filling,
an evaluation unit for calculating the permissible delivery rate of the concrete pump as a function of the permissible rate of ascent determined by the analysis unit and the static filling compound pressure at the formwork arrangement measured by the measuring sensor system.

10. The device according to claim 9 , wherein the measuring sensor system arranged in the region of the formwork arrangement for measuring the static filling compound pressure is configured as a measuring bracket with an integrated pressure or tension measuring sensor overlapping opposite outer formwork surfaces.

11. The device according to claim 9 , wherein the measuring sensor system arranged in the region of the formwork arrangement for measuring the static filling compound pressure is configured as a strain gauge arrangement applied to at least one formwork part or as an inserted pressure sensor.

12. The device according to claim 9 , wherein the analysis unit is connected to a central contruction planning database which contains data records with the required contruction planning information from which the filling compound formulation data and/or the formwork dimension data are derived.

13. The device according to claim 9 , wherein the measuring sensor system arranged on the shuttering arrangement is at least partially wirelessly connected to a computer unit for transmitting the measuring signals, in which computer unit the analysis unit with connected construction planning database and/or the evaluation unit are integrated.

14. The device according to claim 9 , wherein the pumpable filling compound is an in-situ concrete.

15. The device according to claim 9 , wherein it is connected to a pump control unit for transmitting the calculated pump output for the purpose of correspondingly controlling the concrete pump.

16. A non-transitory machine readable medium storing a computer program with program code means for carrying out the steps according to claim 1 , if the computer program is executed on an analysis unit and evaluation unit or a computer unit of a device.
