Abstract

A system for applying a building material, including: a movement device for modifying a site of application in a space; a first component of the building material; a second component of the building material; a mixer for mixing the first component and the second component, the mixer including a drive module with a first coupling element and a mixing chamber module with a second coupling element, the drive module and the mixing chamber module being detachably embodied, and the drive module and the mixing chamber module being actively interconnected in an application state of the system by means of the coupling elements.

First claim

The invention claimed is:

1. A system for applying a building material, the system comprising:
a movement device for changing a site of application within a space;
a first component of the building material;
a second component of the building material; and
a mixer for mixing the first component and the second component,
wherein the mixer includes a drive module with a first coupling element and a mixing chamber module with a second coupling element,
the drive module and the mixing chamber module are configured to be separable from one another by the coupling elements,
the drive module and the mixing chamber module are operatively connected together by the coupling elements when the system is in an application state,
the mixing chamber module includes a drum module and a shaft module configured to be separable from one another,
the shaft module includes the second coupling element, a proximal closure, and an agitating shaft, the agitating shaft being operatively connected to the second coupling element,
at least one of (i) the agitating shaft is fitted with pins on a first portion, and (ii) the agitating shaft has on a second portion a conveying element which is operatively connected to the agitating shaft and to the second coupling element, and
the first component includes a pumpable concrete and the second component includes an accelerating admixture.

2. The system as claimed in claim 1 , wherein the mixer is arranged on a head of the movement device so that the mixer is situated in a region of the site of application.

3. The system as claimed in claim 1 , wherein the drive module is arranged on the movement device, and the mixing chamber module is separated from the movement device when it is in a state separated from the drive module.

4. The system as claimed in claim 1 , wherein the first coupling element and the second coupling element each comprise a toothing, and the drive module and the mixing chamber module are operatively connected together mechanically in the application state.

5. The system as claimed in claim 1 , wherein the drum module includes a drum with at least one inlet, one outlet, and a distal closure.

6. The system as claimed in claim 5 , wherein at least one of (i) the drum of the drum module is in one piece and (ii) the drum of the drum module is tubular.

7. The system as claimed in claim 5 , wherein at least one of the proximal closure and the distal closure include a protection plate on a side which faces toward the drum.

8. The system as claimed in claim 5 , wherein the drum includes at least one first inlet and one second inlet in a first end region of the drum, and the outlet is arranged in a second end region of the drum.

9. The system as claimed in claim 1 , wherein at least on of (i) the conveying element is a screw conveyor, and (ii) the conveying element is configured to be removable from the agitating shaft.

10. The system as claimed in claim 1 , wherein the drive module includes a support device which is connected to a distal closure in the application state, and the distal closure has at least one bearing for the agitating shaft.

11. The system as claimed in claim 1 , wherein the agitating shaft is fitted with pins on the first portion.

12. The system as claimed in claim 1 , wherein the agitating shaft has on the second portion the conveying element which is operatively connected to the agitating shaft and to the second coupling element.

13. A mixer for use in a system comprising:
a drive module with a first coupling element; and
a mixing chamber module with a second coupling element,
wherein the drive module and the mixing chamber module are configured to be separable from one another by the coupling elements, and the drive module and the mixing chamber module are operatively connected together by the coupling elements when the system is in an application state,
the mixing chamber module includes a drum module and a shaft module configured to be separable from one another,
the shaft module includes the second coupling element, a proximal closure and an agitating shaft, the agitating shaft being operatively connected to the second coupling element,
at least one of (i) the agitating shaft is fitted with pins on a first portion, and (ii) the agitating shaft has on a second portion a conveying element which is operatively connected to the agitating shaft and to the second coupling element, and
the mixer is configured to mix a first component including a pumpable concrete and a second component including an accelerating admixture.
