Embodiment Construction

[0027] figure 1 An installation tool 10 is shown for inserting an anchor rod 12. The anchor rod 12 is inserted into a borehole (not shown here) in a foundation and fixed in the foundation, for example, by means of a hardenable substance. Such hardenable substances include at least two chemical components that are injected into the borehole with or without mixing and react and harden with each other in the borehole, wherein a material bond is created between the base, the hardened substance and the anchor rod And / or form-locking connection. The anchor rod is screwed into a drilled hole filled with a hardenable substance to mix and harden the chemical components with each other. The anchor rod 12 may for example have a thread. However, it is also conceivable that other devices are provided on the anchor rod 12 to transmit the load, such as ribs or protrusions, or the anchor rod 12 is formed smoothly on the outside.

[0028] The installation tool 10 has a housing 14 including a c...

Abstract

The invention relates to a setting tool (10) for inserting an anchor rod (12) into a bore hole filled with a curable mass or filled with a cartridge containing a curable mass, comprising a housing (14), which has a receptacle (22) for the anchor rod (12), into which the anchor rod (12) can be inserted in the longitudinal direction (L) and in which the anchor rod can be fixed. According to the invention, at least one clamping element (28) is present, which is associated with the receptacle (22) and is tilted at an angle (alpha) from the longitudinal axis of the receptacle (22) and is supported in a guide in the receptacle (22) in such a way that the clamping element (28) can be moved from a receiving position, in which the anchor rod (12) can be inserted into the receptacle (22) in the longitudinal direction (L), to a clamping position, in which the anchor rod (12) is fixed in the receptacle (22) in the circumferential direction, by rotating the housing (14) relative to the anchor rod (12), a force- and form-closed connection thus being established between the anchor rod (12) and the setting tool (10). The setting tool can be released from the anchor rod by simply rotating the setting tool opposite the setting direction.

Description

Technical field [0001] The present invention relates to an installation tool for inserting an anchor rod into a borehole. The installation tool includes a housing. The housing has a receiving part for the anchor rod. The anchor rod is inserted in the direction and fixed in the receiving part. The invention also relates to a method for installing an anchor rod with such an installation tool. Background technique [0002] The installation tool is used to insert the anchor rod into a borehole in which the anchor rod is fixed by means of, for example, a hardenable substance such as a chemical mortar cylinder. These bolts are usually not used for a tool point, such as a hexagon, so the installation tool must act directly on the bolt. [0003] An installation tool is known from the prior art, for example, which is screwed onto the thread of such an anchor rod. However, with these installation tools, the anchor rod can only be rotated in one direction, because the installation tool is ...
